The present invention relates to a wireless communication system and particularly to a method and a device therefor, the method comprising the steps of: detecting an SSB, the SSB comprising 15 kHz-granularity-based offset information; determining, on the basis of the 15 kHz-granularity-based offset information, a subcarrier offset used to identify the frequency position of a CORESET linked to the SSB; and monitoring, on the basis of the subcarrier offset, the CORESET linked to the SSB.

In an embodiment, a method comprises: sending a message from a master unit of a distributed antenna system to a remote unit of the distributed antenna system, wherein the message includes a list of service frequencies and applied standards for a base station; sending a downlink signal generated based on a base station signal from the master unit to the remote unit; decoding the downlink signal based on the list of service frequencies and applied standards for the base station; extracting a base station clock signal from the decoded downlink signal; and synchronizing an internal clock of the remote unit to the base station clock using the extracted base station clock signal.

A method for adjusting a target clock of a wireless device and a wireless device thereof are provided. The method includes receiving two consecutive broadcast packets from a transmitter to obtain time information corresponding to each of the two broadcast packets; obtaining a time interval between the two broadcast packets according to the time information; and adjusting the target clock of the wireless device according to the time interval and a target value, to achieve the effect of automatically adjusting the target clock, the target clock being related to waking of the wireless device from a standby mode.

In performing wireless communication between terminals to perform time difference measurement and propagation time measurement, first and second terminals that transmit a signal at least once in attempting space-time synchronization are included. The first terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the second terminal, adds a positive or negative phase to the measured reception phase, and makes a report to the second terminal. The second terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the first terminal, and makes a report to the first terminal. The first and second terminals obtain a time difference or propagation time according to a reception phase measured by a local device and reported from a counterpart, and obtain additional information based on a phase reflected in the time difference or propagation time.

Various embodiments herein provide techniques for radio link monitoring (RLM) evaluation periods for in-sync and out-of-sync detection in new radio unlicensed (NR-U) spectrums. Additionally, embodiments provide techniques for reference signal time difference (RSTD) timing uncertainty configuration. Other embodiments may be described and claimed.

A UE receives second baseband signals carried on a second carrier frequency (f.sub.2) transmitted by at least one repeater. The second baseband signals carry data signals transmitted from a base station and are derived from first baseband signals carried on a first carrier frequency (f.sub.1) transmitted from the base station. The UE estimates CPEs in a first set of OFDM symbols based on PT-RSs included in the received second baseband signals. The PT-RSs are transmitted by the base station on the first carrier frequency (f.sub.1) and forwarded to the UE on the second carrier frequency (f.sub.2) through the at least one repeater. The UE detects the data signal based on the received second baseband signals and the estimated CPEs in the first set of OFDM symbols.

Auto-recovery from RF signal acquisition failure may be provided in a portable computing device. A field-calculated frequency-temperature (FT) curve is used to apply temperature compensation to a crystal oscillator associated with RF transceiver circuity of the device. In response to acquisition failure, it may be determined whether a deviation between the field-calculated FT curve and a factory-set FT curve exceeds threshold criteria. In response to acquisition success, the field-calculated FT curve may be refined based on frequency error information. However, in response to acquisition failure and a determination that the deviation exceeds the threshold criteria, information defining the field-calculated FT curve may be replaced with information defining the factory-set FT curve.

Synchronizing devices in a network. In one example, a first communication interface of a first communication device transmits a first message through a first communication path in a mesh network. The first communication path includes the first device, a second device, and a remote server. The first message includes a status of the first device. The first communication interface is switched to a sleep mode after transmission of the first message. Subsequently, the communication interface switches from the sleep mode to an awake mode. While the first communication interface is in the awake mode, the first communication interface transmits a second message through a second communication path in the mesh network. The second communication path includes the first device, a third device, and the remote server.

A clocked electronic device, such as a wireless magnetic resonance (MR) receive coil (20), comprises a wireless receiver or transceiver (30) configured to receive a propagation-delayed wireless clock synchronization signal (54) comprising first and second propagation-delayed carrier signals at respective first and second carrier frequencies separated by a frequency difference, a clock (60) comprising a local oscillator (62) driving a digital counter (64), and at least one electronic signal processing component (66) configured to perform clock synchronization. This includes determining a wrap count (k) from a phase difference (.sub.1) between phases of the first and second propagation-delayed carrier signals, unwrapping a wrapped phase (.sub.2,wrapped) of the propagation-delayed wireless clock synchronization signal using the wrap count to generate an unwrapped phase (.sub.2,wrapped), and synchronizing the clock using the unwrapped phase.

In one embodiment, a method comprises: detecting, by a constrained network device in a low power and lossy network, a loss of synchronization with a neighboring network device based on a determined absence of a prescribed transmission activity by the neighboring network device within a prescribed listening interval that is limited to a prescribed guard time according to a wireless time-slotted transmission protocol; and executing, by the constrained network device, localized sync recovery based on shifting a next listening interval to a shifted listening interval based on selectively shifting, based on a selected shift amount, the prescribed guard time of a corresponding next instance of the prescribed listening interval, enabling the constrained network device to recover synchronization with the neighboring network device based on detecting the prescribed transmission activity that is outside the prescribed listening interval and within the shifted listening interval.
