Abstract: Aspects are described for a user equipment (UE) comprising a first antenna panel and a second antenna panel to enable wireless communication with a first base station and a second base station respectively and a processor communicatively coupled to the first antenna panel and the second antenna panel. The processor is configured to determine that a total transmission power of the first antenna panel and the second antenna panel is greater than a threshold and determine a first back-off value for the first antenna panel and a second back-off value for the second antenna panel. The processor is further configured to generate a report that indicates the first back-off value and the second back-off value and transmit, via the first antenna panel or the second antenna panel, the report.

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: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

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.
