[0028] The digital processing circuit 210 may be arranged to control operations of the communication control circuit 201, and perform digital processing for the communication control circuit 201. The (M+1) analog and RF circuits 220_0, 220_1, . . . , 220_(M1) and 220_M may be arranged to perform analog and RF processing on multiple analog and RF processing paths (e.g., the signal paths starting from the digital processing circuit 210, passing through the (M+1) analog and RF circuits 220_0, 220_1, . . . , 220_(M1) and 220_M as well as the (M+1) antenna tuners Tuner(0), Tuner(1), . . . , Tuner(M1) and Tuner(M), and reaching the (M+1) antennas ANT(0), ANT(1), . . . , ANT(M1)) for the communication control circuit 201. In addition, the switch circuit 230 may be arranged to provide multiple candidate paths between the (M+1) analog and RF circuits 220_0, 220_1, . . . , 220_(M1) and 220_M (or the (M+1) FE circuits 221_0, 221_1, . . . , 221_(M1) and 221_M thereof) and the (M+1) antenna tuners Tuner(0), Tuner(1), . . . , Tuner(M1) and Tuner(M), such as (M+1) connection paths at a time, for performing the antenna selection for the communication control circuit 201 under control of the digital processing circuit 210.

For better comprehension, the multiple predetermined antenna-tuning configurations may be regarded as multiple predetermined tuner states of the aforementioned any antenna tuner Tuner(m) for being selected, and the digital processing circuit 210 may select any tuner state from the multiple predetermined tuner states when there is a need. For example, the antenna tuning performed on the antenna ANT(m) by the antenna tuner Tuner(m) may comprise aperture tuning and impedance tuning, where the aperture tuning may be regarded as coarse tuning of the antenna tuning, and the impedance tuning may be regarded as fine tuning of the antenna tuning.

[0029] FIG. 3 illustrates an antenna tuning control scheme of the method according to an embodiment of the present invention. The aforementioned any antenna tuner Tuner(m) may be implemented by way of the antenna network 340 shown in FIG. 3, and the FE circuit 221_m that is currently coupled to the aforementioned any antenna tuner Tuner(m) via the switch circuit 230, such as any Tx and Rx FE circuit 221_m among the Tx and Rx FE circuits {221_m|m=0, 1, . . . , (M1)} or the Rx FE circuit 221_M, may be illustrated as the FE circuit 321 (labeled T/Rx for brevity). For example, the antenna network 340 may comprise at least one capacitor (e.g., one or more capacitors) such as the tunable capacitor C.sub.1, at least one inductor (e.g., one or more inductors) such as the tunable inductor L.sub.1, and at least one switch such as multiple switches, but the present invention is not limited thereto.

[0030] FIG. 4 illustrates a working flow of the method regarding a certain stage among multiple stages according to an embodiment of the present invention. The method can be applied to the aforementioned any wireless transceiver device such as the wireless transceiver device #n or any of the wireless transceiver devices 101, 102, etc. Taking the wireless transceiver device 101 as an example of the wireless transceiver device #n, the communication control circuit 121 within the wireless transceiver device 101 and the aforementioned at least one antenna of the communication control circuit 121 may be implemented by way of the communication control circuit 201 and the (M+1) antennas ANT(0), ANT(1), . . . , ANT(M1) and ANT(M) shown in FIG. 2, respectively, and the aforementioned any antenna tuner Tuner(m) therein may be implemented by way of the antenna network 340 shown in FIG. 3. In addition, the multiple stages may comprise an offline stage and a runtime stage, and the associated operations of the wireless transceiver device #n may comprise:

[0031] (1) during the offline stage, the wireless transceiver device #n may utilize the communication control circuit 201 within the wireless transceiver device #n to characterize antenna performance under different switch states and tuner states offline in order to obtain characterization data (e.g., an antenna characteristic Q.sub.j, k for an antenna ANT(j) with a corresponding antenna tuner Tuner(j) in a tuner state k among all tuner states {k} thereof), and setup one or more static switch state preferences based on the characterization data, where the communication control circuit 201 may be arranged to store the characterization data as predetermined characterization data in the storage device 131, for being retrieved and used as reference data in the runtime stage, and the one or more static switch state preferences may represent the likelihood that switch states will be chosen; and

[0032] (2) during the runtime stage, the wireless transceiver device #n may utilize the communication control circuit 201 within the wireless transceiver device #n to dynamically determine (or select) any action D(i) among multiple candidate actions {D(i)|i=1, 2, 3, 4} with joint considerations of antenna selection and tuning based on various types of indicators, etc., and perform the aforementioned any action D(i), in order to achieve the optimized system performance; where the multiple candidate actions {D(i)|i=1, 2, 3, 4} may also be referred to as the candidate actions {D1, D2, D3, D4} for brevity. For example, in the runtime stage, the communication control circuit 201 may operate according to the working flow shown in FIG. 4, and more particularly, execute Steps S05 and S10, execute a selected step among Steps S11 to S14, depending on the determined action D(i) such as one of the candidate actions {D1, D2, D3, D4}, and selectively execute at least one portion of steps (e.g., a portion of steps or all steps) among Steps S15 to S19. For example, the associated indicators involved with the method may comprise: [0033] (1) Performance indicators (or Performance): the throughput (T-put), the modulation and coding scheme (MCS), the resource block (RB) and the block error rate (BLER) regarding the antenna ANT(m); [0034] (2) Channel Quality indicators (or Channel Quality): the reference signal received power (RSRP), the transmission power (TxP), the power headroom report (PHR) and the signal-to-noise ratio (SNR) regarding the antenna ANT(m); [0035] (3) Antenna indicators (or Antenna): the impedance measurement(s) such as the measurement result(s) of the impedance of the antenna ANT(m); and [0036] (4) Application Processor (AP) Scenario indicators (or AP Scenario): one or more sensor readings of at least one sensor (e.g., gyroscope (gyro) sensor), and at least one Universal Serial Bus (USB) state such as at least one USB plug-in state regarding whether at least one USB port is plugged in; [0037] but the present invention is not limited thereto. In some examples, the associated indicators may vary.

[0038] In Step S05, the communication control circuit 201 (or the digital processing circuit 210) may collect at least the indicator(s) of each antenna ANT(m) among the (M+1) antennas ANT(0), ANT(1), . . . , ANT(M1) and ANT(M).

[0039] In Step S10, the communication control circuit 201 (or the digital processing circuit 210) may determine an action D(i) of a state change, with joint considerations of antenna selection and tuning, in order to look for the action D(i) with the largest system benefits based on at least one of the following: the collected indicators (e.g., the Performance indicators, the Channel Quality indicators, the Antenna indicators and the AP Scenario indicators), pre-defined antenna characteristics (e.g., the characterization data such as the antenna characteristic Q.sub.j, k for the antenna ANT(j) with the antenna tuner Tuner(j) in the tuner state k), and one or more switch state preferences. For example, the digital processing circuit 210 may obtain the pre-defined antenna characteristics by measuring the RSRP and/or the TxP of the tuner states of the antenna tuner Tuner(m), but the present invention is not limited thereto. In another example, the digital processing circuit 210 may obtain the pre-defined antenna characteristics by deriving from the measured data.

[0040] The one or more switch state preferences mentioned in Step S10 may comprise the one or more static switch state preferences, but the present invention is not limited thereto. For examples, the one or more switch state preferences may comprise the one or more static switch state preferences and/or one or more dynamic switch state preferences, where the one or more switch state preferences may have default values such as the one or more static switch state preferences, and the digital processing circuit 210 may update the one or more switch state preferences with one or more changing amounts {A} (e.g., increments or decrements) to dynamically adjust the one or more switch state preferences, which may be regarded as the one or more dynamic switch state preferences.

[0041] After executing Step S10, the communication control circuit 201 (or the digital processing circuit 210) may obtain the determined action D(i) such as one of the candidate actions {D1, D2, D3, D4}, and execute the corresponding step among Steps S11 to S14 to perform the corresponding antenna-related control operation, in order to remain no state change, change either the tuner state or the switch state, or change both of the tuner state and the switch state.

[0042] In Step S11, when the determined action D(i) is the determined action D1, the communication control circuit 201 (or the digital processing circuit 210) may remain both of the switch state and the tuner state unchanged (labeled Remain unchanged for brevity).

[0043] In Step S12, when the determined action D(i) is the determined action D2, the communication control circuit 201 (or the digital processing circuit 210) may change the switch state only.

[0044] In Step S13, when the determined action D(i) is the determined action D3, the communication control circuit 201 (or the digital processing circuit 210) may change the tuner state only.

[0045] In Step S14, when the determined action D(i) is the determined action D4, the communication control circuit 201 (or the digital processing circuit 210) may change both of the switch state and the tuner state.

[0046] In Step S15, the communication control circuit 201 (or the digital processing circuit 210) may collect the latest indicators based on the new state(s) to perform comparison versus the previous state(s). For example, if Step S12 is just executed before Step S15 is executed, the new state(s) may comprise the new switch state, and the previous state(s) may comprise the previous switch state. In another example, if Step S13 is just executed before Step S15 is executed, the new state(s) may comprise the new tuner state, and the previous state(s) may comprise the previous tuner state. In yet another example, if Step S14 is just executed before Step S15 is executed, the new state(s) may comprise the new switch state and the new tuner state, and the previous state(s) may comprise the previous switch state and the previous tuner state.

[0047] In Step S16, the communication control circuit 201 (or the digital processing circuit 210) may determine if the Performance indicator(s) (or the Performance) of the new state(s) meet expectation. If Yes, Step S17 is entered; if No, Step S18 is entered.

[0048] In Step S17, the communication control circuit 201 (or the digital processing circuit 210) may remain the new state(s) unchanged (labeled Remain unchanged for brevity).

[0049] In Step S18, the communication control circuit 201 (or the digital processing circuit 210) may restore the previous state(s).

[0050] In Step S19, the communication control circuit 201 (or the digital processing circuit 210) may selectively update the one or more dynamic switch state preferences. For example, the digital processing circuit 210 may adjust the one or more switch state preferences with the one or more changing amounts {4} on top of the one or more static switch state preferences based on the quality of previous decisions.

[0051] For better comprehension, the method may be illustrated with the working flow shown in FIG. 4, but the present invention is not limited thereto. According to some embodiments, one or more steps may be added, deleted, or changed in the working flow shown in FIG. 4. For example, after Step S19 is executed, the communication control circuit 201 (or the digital processing circuit 210) may re-enter a previous step (e.g., Step S05) to perform the operations of at least one partial working flow within the working flow shown in FIG. 4. For brevity, similar descriptions for these embodiments are not repeated in detail here.

[0052] FIG. 5 illustrates a 1T2R joint antenna selection and tuning architecture (e.g., the joint antenna selection and tuning architecture 200 shown in FIG. 2 in a special case of M=1) in at least one default state according to an embodiment of the present invention. In this joint antenna selection and tuning architecture, when M=1, the aforementioned any Tx and Rx FE circuit 221_m among the Tx and Rx FE circuits {221_m|m=0, 1, . . . , (M1)} and the Rx FE circuit 221_M may be respectively implemented as the Tx and Rx FE circuit 221_0 equipped with the transmitter Tx(0) (or Tx0) and the receiver Rx(0) (or Rx0) and the Rx FE circuit 221_1 equipped with the receiver Rx(1) (or Rx1), respectively labeled as {{Tx0, Rx0}, Rx1} for better comprehension. For example, the switch circuit 230 (labeled Switch for brevity) may be in a default switch state 0 thereof as illustrated with the Tx0/Rx0 path and the Rx1 path shown in FIG. 5, the antenna tuner Tuner(0) may be in a default tuner state 0 thereof, and the antenna tuner Tuner(1) may be in a default tuner state 0 thereof, where the aforementioned at least one default state may comprise the switch state 0 of the switch circuit 230, the tuner state 0 of the antenna tuner Tuner(0) and the tuner state 0 of the antenna tuner Tuner(1), but the present invention is not limited thereto. According to some embodiments, the aforementioned at least one default state, the switch state of the switch circuit 230, the tuner state of the antenna tuner Tuner(0), and/or the tuner state of the antenna tuner Tuner(1) may vary.

[0053] The combination (k0, k1, k2) of the switch state k0 (e.g., any switch state k0 among the switch states {0, 1}) of the switch circuit 230, the tuner state k1 (e.g., any tuner state k1 among the tuner states {0, 1, . . . }) of the antenna tuner Tuner(0) and the tuner state k2 (e.g., any tuner state k2 among the tuner states {0, 1, . . . }) of the antenna tuner Tuner(1) may be regarded as a hybrid state (k0, k1, k2) of the 1T2R joint antenna selection and tuning architecture. When the digital processing circuit 210 determines the action D(i) as the determined action D1 in Step S10, the communication control circuit 201 may execute Step S11 corresponding to the determined action D1 keep staying in the current hybrid state (k0, k1, k2). When the digital processing circuit 210 determines the action D(i) as any determined action among the determined actions D2, D3 and D4 in Step S10, the communication control circuit 201 may execute the step corresponding to the aforementioned any determined action among Steps S12, S13 and S14, to make the 1T2R joint antenna selection and tuning architecture transit from one hybrid state (k0, k1, k2) to another hybrid state (k0, k1, k2). As shown in FIG. 5, the combination (0, 0, 0) of the switch state 0 of the switch circuit 230, the tuner state 0 of the antenna tuner Tuner(0) and the tuner state 0 of the antenna tuner Tuner(1) may be regarded as the hybrid state (0, 0, 0).

[0054] In Step S10, the digital processing circuit 210 may determine the action D(i) as the determined action D(i) among the determined actions D1, D2, D3 and D4 according to the collected indicators (e.g., the indicators collected in Step S05) obtained in the runtime stage and some other indicators obtained in the offline stage. Regarding any antenna ANT(j) among the antennas {ANT(m)|m=0, 1, . . . , (M1), M}, the indicators for determining the action D(i) in Step S10 may comprise one or a combination of the following: the antenna characteristic Q.sub.j, k for the antenna ANT(j) with the corresponding antenna tuner Tuner(j) in the tuner state k(e.g., the tuner state k(j+1) of the antenna tuner Tuner(j)), the switch state preference P.sub.k0 for the switch state k0, the PHR PHR.sub.j, the SNR SNR.sub.j and the RSRP RSRP.sub.j, but the present invention is not limited thereto. According to some embodiments, the indicators for determining the action D(i) in Step S10 may vary. In addition, the digital processing circuit 210 may perform at least one comparison operation (e.g., one or more comparison operations), and more particularly, compare at least one indicator among the indicators with at least one predetermined threshold of the aforementioned at least one indicator, in order to determine the action D(i). For example, the aforementioned at least one indicator may comprise the PHR PHR.sub.j, and the aforementioned at least one predetermined threshold may comprise the PHR threshold THD.sub.PHR. In a first comparison operation, the digital processing circuit 210 may compare the PHR PHR.sub.j with the PHR threshold THD.sub.PHR, for determining the action D(i) at least according to whether the PHR PHR.sub.j reaches (e.g., is greater than or equal to) the PHR threshold THD.sub.PHR. For another example, the aforementioned at least one indicator may comprise the SNR SNR.sub.j, and the aforementioned at least one predetermined threshold may comprise the SNR threshold THD.sub.SNR. In a second comparison operation, the digital processing circuit 210 may compare the SNR SNR.sub.j with the SNR threshold THD.sub.SNR, for determining the action D(i) at least according to whether the SNR SNR.sub.j reaches (e.g., is greater than or equal to) the SNR threshold THD.sub.SNR.

For example, the digital processing circuit 210 may determine the action D(i) as the determined action D3 in Step S10, and change the tuner state only in Step S13, and more particularly, change the tuner state based on the collected indicators, to make the 1T2R joint antenna selection and tuning architecture transit from the hybrid state (0, 0, 0) to the hybrid state (0, 1, 0).

For example, the digital processing circuit 210 may determine the action D(i) as the determined action D3 in Step S10, and change the tuner state only in Step S13, and more particularly, change the tuner state based on the collected indicators, to make the 1T2R joint antenna selection and tuning architecture transit from the hybrid state (0, 0, 0) to the hybrid state (0, 2, 0).

For brevity, similar descriptions for this embodiment are not repeated in detail here.

[0070] FIG. 13 illustrates a working flow of the method regarding the multiple stages (e.g., the offline stage and the runtime stage) according to an embodiment of the present invention.

[0071] In Step S30, during the offline stage among the multiple stages, the wireless transceiver device 1200 (or at least one circuit therein, such as the processing circuit 1210, the communication control circuit 201 and/or the digital processing circuit 210) may store the pre-defined database 200 DB in the storage device 1230 within the wireless transceiver device 1200 under control of a manufacturing tool. For example, the manufacturing tool may represent a manufacturing tool device (e.g., a personal computer such as a desktop computer or a laptop computer) coupled to the wireless transceiver device 1200, but the present invention is not limited thereto. In some examples, the manufacturing tool may represent a manufacturing tool program module running on the processing circuit 1210 within the wireless transceiver device 1200.

[0072] In Step S31, during the runtime stage among the multiple stages, the communication control circuit 201 (or the digital processing circuit 210 therein) may dynamically determine any action D(i) of the state change among multiple actions {D(i)|i=1, 2, 3, 4} (e.g., the determined actions D2, D3 and D4) according to a set of runtime measurements and the pre-defined database 200 DB in the storage device 1230 within the wireless transceiver device 1200. For example, the operation of Step S31 may comprise the operation of Step S10 shown in FIG. 4, and more particularly, comprise the operations of Steps S05 and S10 shown in FIG. 4.

[0073] In Step S32, during the runtime stage, the communication control circuit 201 (or the digital processing circuit 210 therein) may perform the any action D(i) (e.g., the action D(i) that is just determined in Step S31) to selectively adjust the hybrid state (k0, k1, . . . , k(M+1)) of the wireless transceiver device 1200, such as the combination (k0, k1, . . . , k(M+1)) of the switch state k0 of the switch circuit 230 for the antenna selection within the communication control circuit 201 and at least one tuner state k(m+1) (e.g., the tuner states {k(m+1)|m=0, . . . , M}) of at least one antenna tuner Tuner(m) (e.g., the antenna tuners {Tuner(m)|m=0, . . . , M}) for the antenna tuning within the communication control circuit 201, for performing at least one adjustment among a switch state adjustment of the switch state k0 and a tuner state adjustment of the tuner state k(m+1). For example, the operation of Step S32 may comprise the operation of any step among Steps S11 to S14 shown in FIG. 4.

In addition, the pre-defined database 200 DB may comprise the characterization data that is obtained during the offline stage, wherein during the runtime stage, the communication control circuit 201 may dynamically determine the any action D(i) according to the set of runtime measurements and the characterization data. More particularly, the characterization data may comprise a set of antenna characteristics {Q.sub.j, k} (e.g., the antenna characteristic Q.sub.j, k for the antenna ANT(j) with the corresponding antenna tuner Tuner(j) in the tuner state k among all tuner states {k} thereof) corresponding to the switch state and tuner state characterization of the switch state k0 and the aforementioned at least one tuner state k(m+1). For example, the set of antenna characteristics may be measured and/or customized, and stored as at least one portion of the pre-defined database 200 DB. The set of antenna characteristics may comprise one or a combination of a RSRP measurement (e.g., a measurement result of the RSRP), a TxP measurement (e.g., a measurement result of the TxP), a total isotropic sensitivity (TIS) measurement (e.g., a measurement result of the TIS) and a total radiated power (TRP) measurement (e.g., a measurement result of the TRP) at each state among multiple hybrid states {(k0, k1, . . . , k(M+1))} (e.g., all hybrid states {(k0, k1, . . . , k(M+1))}) of the wireless transceiver device 1200. Additionally, the characterization data may further comprise at least one state preference of at least one state among all tuner and switch states (e.g., all switch states {k0} and all tuner states {{k1}, . . . , {k(M+1)}}), such as the switch state preference P.sub.k0 for the state k of the switch circuit 230 and the tuner state preference PT.sub.k(m+1) for the state k(m+1) of the antenna tuner Tuner(m), for controlling the likelihood of the aforementioned at least one state being selected during the runtime stage.

[0075] For better comprehension, the method may be illustrated with the working flow shown in FIG. 13, but the present invention is not limited thereto. According to some embodiments, one or more steps may be added, deleted, or changed in the working flow shown in FIG. 13. For example, after Step S32 is executed, the communication control circuit 201 (or the digital processing circuit 210) may execute at least one subsequent step in the runtime stage, where the aforementioned at least one subsequent step may comprise Steps S15 to S19 shown in FIG. 4. For brevity, similar descriptions for these embodiments are not repeated in detail here.
