摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for SSB processing in a 5G-NR network, the processing circuitry is to decode a MIB and a SIB received from a gNB. An RRC IE within the SIB is obtained. The RRC IE includes a bitmap associated with an SSB transmission pattern, where a length of the bitmap indicates a number of beams used within a cell of the gNB. SSB indices corresponding to candidate SSB positions within a discovery reference signal (DRS) transmission duration are determined based on the number of beams. Synchronization with the cell of the to gNB is performed using SSBs received within the DRS transmission duration, the SSBs selected based on the determined SSB indices.

摘要： An apparatus for use in a base station includes processing circuitry coupled to a memory. To configure the base station for channel access in a New Radio (NR) unlicensed (NR-U) network operating in an unlicensed spectrum, the processing circuitry is to perform an LBT procedure for a transmission occasion of a plurality of transmission occasions within a Discovery Measurement Timing Configuration (DMTC) window of a communication channel in the unlicensed spectrum. The transmission occasion is configured within a slot of a plurality of slots forming the DMTC window. A Discovery Reference Signal (DRS) is encoded for transmission to a UE on the communication channel, based on the successful completion of the LBT procedure. The DRS includes a PSS, a SSS, and a PBCH. A RACH procedure is performed with the UE, the RACH procedure initiated based on the PSS, the SSS, and the PBCH.
