摘要： A user equipment (UE) is configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, identify a collision between a cell-specific downlink reception and a cell-specific uplink transmission and implement a HD-FDD collision handling technique. A UE may also be configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, perform a first cell-specific uplink transmission at a first time and perform a first cell-specific downlink reception at a second time, wherein a guard period represents a time duration between the first time and the second time during which the UE is not to perform a second different cell-specific uplink transmission or a second different cell-specific downlink reception.

摘要： A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

摘要： A user equipment (UE) is configured to receive a synchronization signal block (SSB) transmission with a first subcarrier spacing (SCS) in an SSB burst window (SSBW), decode the SSB transmission to determine parameters for a control resource set 0 (CORESET #0) to be transmitted in the SSBW using a second SCS that is different from the first SCS, monitor physical downlink control channel (PDCCH) candidates in the determined CORESET #0 based on a mapping between the SSB transmission and the CORESET #0 and decode the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.
