Abstract: 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.

Abstract: Methods and systems are disclosed for a UE to manage and measure intra-cell cross link interference (CLI) when served by a base station operating in full-duplex FDD. The signaling may indicate to a victim UE resources to measure to determine the level of CLI from aggressor UEs. The resources used for the CLI measurement may be resources not scheduled by the base station for use by the victim UE for downlink reception, but are scheduled for use by the aggressor UEs for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. The victim UE may report the CLI measurements to the base station for the base station to adjust scheduling of downlink resources to the victim UE. In one aspect, the signaling from the base station may indicate to the victim UE the locations of scheduled downlink symbols that may potentially be impacted by CLI.

Abstract: 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.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).
