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.

The invention relates to a method for allocating radio resources to a transmitting terminal for performing direct communication transmission over a direct link connection. The transmitting terminal receives a system information broadcast from the base station, which comprises information on a temporary transmission radio resource pool, indicating radio resources for performing a direct communication transmission, and comprises configuration information on the resource pool to limit the amount of time that the temporary radio resource pool is usable by the transmitting terminal.

A method of a user equipment (UE) operating with a new radio (NR) radio access technology (RAT). The method comprises receiving synchronization signals and a master information block (MIB) in a first bandwidth (BW) and receiving a physical downlink control channel (PDCCH) in a second BW, wherein the second BW is indicated by an offset in the MIB relative to the first BW and the PDCCH conveys a downlink control information (DCI) format that configures a reception of a first system information block (SIB).

A method is disclosed for determining an appropriate transmit power of a cell based on a desired coverage distance, comprising: initializing, at a cell, a cell reference signal transmit power at a high power level; broadcasting a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell; progressively lowering the cell signal power measure at the cell; broadcasting the lowered cell signal power measure; deriving a plurality of user equipment (UE) attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell; comparing the plurality of UE attach request distances against a maximum distance to obtain a number of UE attach requests received from UEs physically located beyond the maximum distance; and setting the cell reference signal transmit power based on the number of UE attach requests received from beyond the maximum distance, thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on UE attach requests received at the cell.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit beam information associated with a set of cells detected by the base station, wherein the beam information is transmitted to a target base station; and receive, based at least in part on transmitting the beam information to the target base station, one or more random access messages, wherein the one or more random access messages are transmitted by one or more other base stations, wherein the one or more other base stations are associated with one or more cells included in the set of cells detected by the base station. Numerous other aspects are provided.

A method of multiplexing logical channels (LCHs) in configured grants (CG) to enable faster transmission of high priority data in 5G New Radio-Unlicensed (NR-U) is proposed. Two options of imposing a CAPC-based restriction rule on multiplexing a low priority LCH with a high priority LCH are provided. In a first option, a threshold CAPC value is configured via RRC signaling. Data belonging to LCH having a priority lower than the CAPC threshold is not allowed to be multiplexed with data belonging to LCH having a priority higher than the CAPC threshold. In a second option, each CAPC has a flag indicating if the CPAC can have reduced priority via RRC signaling. If the flag is set for the CAPC, then data belonging to LCH assigned with the CAPC cannot be multiplexed with data belonging to lower priority LCHs.
