Devices, systems and methods for collaborative wireless communication in a wireless network are described. One example method includes performing a bidirectional communication with a reference node in the source cluster, receiving, from a destination cluster comprising a second plurality of nodes, a probe generated using a phase associated with the destination cluster, estimating, based on a propagation delay of the probe, a delay parameter, generating, based on the phase associated with the destination cluster and the delay parameter, a channel estimate, and transmitting, to each of the second plurality of nodes, a common message generated using a phase value and a delay value, wherein the phase value and the delay value are derived based on the channel estimate, and wherein the destination cluster is remotely located from the source cluster.

A wireless communication system is provided for reducing the probability that latency before data transmission increases when a mobile station that is actually in sync is judged to be out of sync. A base station causes the timing calculation part to calculate the timing advance (TA) of a transmit timing from the m.sup.th mobile station; causes the timer adaptive control part to obtain the traveling speed or the time variation in TA of the m.sup.th mobile station and, adaptively determines and outputs as the timer update information the length of the m.sup.th first timer within an M number in total of synchronization timers and the length of the second timer of the m.sup.th mobile station and update the length of the m.sup.th first timer; and transmits from the downlink transmission part a downlink signal which contains timer update information.

A method of a terminal, according to an exemplary embodiment of the present disclosure, may comprise: receiving, from a base station, radio resource control (RRC) signaling including measurement gap configuration information (MeasGapConfig) including gap setup information (gapSAT) of synchronization signal blocks (SSBs); obtaining transmission position information of first SSBs and second SSBs transmitted in different positions based on gap configuration (GapConfig) of the gap setup information; receiving the first SSBs and the second SSBs through different beams from the base station based on the obtained transmission position information; and measuring reception powers of the received first SSBs and second SSBs.

An apparatus and method are provided for determining that a second sidelink synchronization reference user equipment extends synchronization coverage of a first sidelink synchronization reference user equipment; for determining a first synchronization error between the first sidelink synchronization reference user equipment and the second sidelink synchronization reference user equipment and a second synchronization error between the first sidelink synchronization reference user equipment and the apparatus; and for determining whether to operate the apparatus as a sidelink synchronization reference user equipment and extend the synchronization coverage of the first sidelink synchronization reference user equipment based on the first synchronization error and the second synchronization error.

The present subject matter relates to a method for operating a node of a communication system. The node is configured to support wireless backhauling in the communication system and support wireless access in the communication system. The method comprises: receiving from a node first data on a backhaul link and second data on an access link, determining transmit times of the first and second data using the received first data and second data, determining a timing error using the determined transmit times.

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides a method performed by a terminal in a wireless communication system and a device for performing same, the method comprising the steps of: measuring a first reference signal transmitted from a first transmission and reception point (TRP) of a base station, and measuring a second reference signal transmitted from a second TRP; calculating a time delay difference between the first reference signal and the second reference signal; receiving, from the base station, terminal report configuration information indicating a report on the time delay difference between the first reference signal and the second reference signal; transmitting information on the time delay difference between the first reference signal and the second reference signal to the base station on the basis of the terminal report configuration information; receiving, from the first TRP and the second TRP, reference signals compensated on the basis of the information on the time delay difference between the first reference signal and the second reference signal; and receiving downlink information from the first TRP and the second TRP on the basis of the compensated reference signals.
