Abstract: A base station of a network configures a first search space having a first search space identification (SearchSpaceId) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceId) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

Abstract: 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.

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: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station, and a processor communicatively coupled to the transceiver. The processor is configured to receive a configuration message from the base station and determine a first set of antenna ports based on the configuration message. The processor is further configured to perform channel estimation on the first set of antenna port and perform or refrain from performing channel estimation on a second set of antenna ports based on the configuration message. The first set of antenna ports and the second set of antenna ports are in a code division multiplexing (CDM) group.

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).
