The present disclosure relates to the field of synchronising a radio frequency (RF) communication system based on the repeated transmission of data at the transmitter and the use of a method for the time synchronous averaging of this data at the receiver. The proposed communication technique uses the fact that the data signal is periodically repeated, without requiring the use of synchronisation data external to the data to be communicated. It enables phase and frequency synchronisation to be maintained when the received signals are very noisy, and even when they have a signal-to-noise ratio of less than 1 or even a negative signal-to-noise ratio (in dB). A significant improvement in the processing gain of the method for time synchronous averaging is advantageously achieved.

Implementations of advanced frequency synchronization in a mobile integrated access backhaul deployment are disclosed. An apparatus includes at least one processor, and at least one non-transitory memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform: estimate a change in a propagation delay at two time instants, measure a time period of the two time instants using a local clock of a network node, wherein the two time instants correspond to a known timing of a received signal, subtract the change of the propagation delay from the measured time period, calculate a difference between the subtracted time period and a known timing of the received signal; and convert the difference to a frequency offset value to synchronize downlink transmission frequency between the network node and a parent node.

In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for measuring one or more synchronization signal block (SSB) beams from a network entity; selecting a highest rated SSB beam from the one or more SSB beams based on one or more selection factors; transmitting, to the network entity, a beam report including an identification of the highest rated SSB beam; initiating a timer in response to transmitting the beam report; determining whether a media access control (MAC) control element (CE) is received from the network entity before expiration of the timer; and performing beam switching from a current SSB beam to the highest rated SSB beam based on a determination that the MAC CE is not received from the network entity before expiration of the timer.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Methods and apparatuses for transmitting synchronization signal in non-anchor carrier are disclosed. A method comprises transmitting a carrier configuration on an anchor carrier; and transmitting a synchronization signal in a non-anchor carrier based on the carrier configuration.

A method for operating a first device (100) in a wireless communication system is proposed. The method may comprise: a step of receiving information related to a sync resource from a base station (300); a step of receiving, from a second device (200), a first sidelink synchronization signal block (S-SSB) through a first resource; a step in which the first S-SSB comprises at least one symbol related to a sidelink primary synchronization signal (S-PSS), at least one symbol related to a sidelink secondary synchronization signal (S-SSS), and at least one symbol related to a physical sidelink broadcast channel (PSBCH); and a step of obtaining slot information related to the first S-SSB.

A communication control device according to one aspect of the present disclosure includes an acquisition unit, a determination unit, and a decision unit. The acquisition unit acquires a synchronization mode of a time division duplex related to a first wireless system. The determination unit determines whether or not interference occurs in a case where the first wireless system and a second wireless system perform wireless communication by the time division duplex in a shared frequency band The decision unit decides a synchronization mode to be used in the first wireless system on the basis of a result of the determination and a synchronization mode related to the first wireless system.

Methods and apparatus are provided for improving the resilience of a network of positioning-unit devices to failure of the reference device that controls the network timebase via timing information in its signal. In certain embodiments a predetermined one of the positioning-unit devices is configured to monitor the reference signal, assess serviceability of that signal and take control of the network if it determines that signal is unserviceable. Continuity of network synchronisation is thereby maintained despite the reference signal being unserviceable. Preferably the predetermined positioning-unit device is configured to obtain information on the reference signal from at least one other positioning-unit device for assessing reference signal serviceability. If the reference device recovers from a failure it can re-enter the network by synchronising its signal to a signal from one of the positioning-unit devices, and may then negotiate with the predetermined positioning-unit device to resume control of the network.

Various embodiments may provide systems and methods for managing transmit (TX) timing of data transmissions. The methods include applying a plurality of radio frequency (RF) channel factors related to data uplink transmissions by the wireless device to a TX timing model configured to provide as an output a TX timing for a data transmission to a base station and a number of carriers for sending the data transmission, and selecting a TX time and a number of carriers for sending a next data transmission to the base station based in part on the TX timing model output.

A self-synchronization sensor system is provided. A self-synchronization sensor system for tracking fast moving assets comprising a plurality of beacons with known coordinates in a tunnel communicating with said plurality of beacons periodically during a synchronization interval and adjusting a beacon interval for each of said plurality of beacons such that one or more beacon messages are transmitted in short time intervals to the plurality of beacons in close proximity. The synchronization interval comprising a plurality of time slots, a first beacon from the plurality of beacons assigned a first time slot from the plurality of time slots within the synchronization interval and launches an origin and a progression of time slot allocation of the plurality of time slots from the origin based on the communication between the plurality of beacons.
