Various other embodiments are possible.

An electronic device includes a first antenna configured to process a first radio frequency (RF) signal within a first frequency band; a second antenna spaced apart from the first antenna configured to process a second RF within a second frequency band different from the first frequency band; a first radio frequency front end (RFFE) and a second RFFE configured to process a third RF signal within a third frequency band different from the first frequency band and the second frequency band; a communication processor electrically connected to the first switch and the second switch; and a memory operatively coupled to the communication processor and configured to store performance information having, at least, a first value indicating an efficiency of the first antenna when performing a first radio communication, and a second value indicating an efficiency of the second antenna when performing the first radio communication. The memory is configured to store instructions that, when executed, cause the communication processor to transmit or receive a signal within at least one of the first frequency band, the second frequency band or the third frequency band, and select an antenna to support the first radio communication among the first antenna and the second antenna based on the performance information having the first value or the second value. The first RFFE and the second RFFE support the first radio communication within the third frequency band.

Apparatus and methods for sounding reference signal (SRS) switching are provided. In certain embodiments, a controller internal to the power amplifier module initiates a sequence of instructions, in response to a single command, that cause the antenna switch to actuate for transmission of the sounding reference signal symbol to a second antenna. The user equipment notifies the base station associated with the mobile device to withhold blanking symbols before and after a sounding reference signal symbol.

An ultra-wideband (“UWB”) communication system comprising a transmitter having two transmit antennas and a receiver having a single receive antenna. Respective selected portions of the UWB signal are transmitted by the transmitter via each of transmit antennas is received at the receive antenna. By comparing the phases of the received signal portions, the phase difference of departure can be determined. From this phase difference and the known distance, d, between the transmit antennas, the Cartesian (x, y) location of the transmitter relative to the receiver can be directly determined.

Methods provide wireless communication using a plurality of Antenna Processing Units APUs distributed along a radio stripe and sharing a bus along the radio stripe. Access is provided to a plurality of APU activation/deactivation states for a respective plurality of environmental conditions, wherein each one of the plurality of APU activation/deactivation states defines APUs of the plurality of APUs that are activated and APUs of the plurality of APUs that are deactivated for the respective one of the plurality of environmental conditions. Responsive to detecting a first one of the plurality of environmental conditions, a first one of the plurality of APU activation/deactivation states corresponding to the first one of the plurality of environmental conditions is applied to activate a first subset of the APUs and to deactivate a second subset of the APUs, wherein the first and second subsets of APUs are mutually exclusive.

A terminal according to one aspect of the present disclosure includes a control section that, when spatial relation information is not configured for at least one SRS resource in one or more sounding reference signal (SRS) resource sets, uses, for a spatial relation for a target SRS resource in the one or more SRS resource sets, a reference signal for quasi-co-location (QCL) of a specific downlink resource, and a transmitting section that performs uplink transmission by using the spatial relation. According to one aspect of the present disclosure, it is possible to appropriately determine a reference signal for at least one of QCL and path loss calculation for uplink transmission.

The first configuration information is used to determine at least one Sounding Reference Signal (SRS) resource set group, each SRS resource set group in the at least one SRS resource set group includes at least one SRS resource set, and each SRS resource set in the at least one SRS resource set comprises at least one SRS resource. For multiple SRS resources in a same SRS resource set transmitted on a same slot, there is an interval of Y symbols between two adjacent SRS resources in the multiple SRS resources, and a value of Y is determined based on a subcarrier spacing of the SRS resources and/or a first capability of the first terminal.

An electronic device that uses an arbitrary transmit polarization is described. This electronic device includes: a first antenna having a first predefined polarization; and a second antenna having a second predefined polarization, where the second predefined polarization is different from the first predefined polarization. During operation, an interface circuit in the electronic device selectively transmits, from the first antenna, first wireless signals corresponding to the packet or the frame. Moreover, the interface circuit selectively transmits, from the second antenna, second wireless signals corresponding to the packet or the frame, where the second wireless signals have a same magnitude as the first wireless signals, and the second wireless signals are transmitted from the second antenna concurrently (or at the same time) as the first wireless signals are transmitted from the first antenna. Note that the interface circuit may dynamically modify the transmit polarization during the communication.
