Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure for a first beam group in a cell including the first beam group and a second beam group. The UE may selectively transmit a beam failure recovery request for the first beam group based at least in part on a determination of uplink resource availability in the second beam group. Numerous other aspects are described.

Abstract: A network node may transmit an RS to a UE in a symbol or a slot. The RS may extend over a plurality of downlink subbands that have non-contiguous subcarriers in the symbol or the slot. At least two downlink subbands in the plurality of downlink subbands may be separated by an uplink subband in the symbol or the slot. The plurality of downlink subbands and the uplink subband may be associated with a subband full duplex operation at a network node. The RS may include a CSI-RS. The UE may measure the RS from the network node in the symbol or the slot. The UE may generate at least one CSI metric based on the measurement of the RS. The network node may receive a CSI report from the UE based on the RS and at least one CSI metric.

Abstract: A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.

Abstract: Apparatuses and methods for switching between SBFD and HD modes for different periodicities are described. An apparatus is configured to operate in a SBFD mode associated with a SBFD operation or a HD mode. SBFD operations are associated with SB sets and the HD mode is associated with time/frequency resource sets. The apparatus is configured to obtain first indications of a time/frequency location for each SB, or second indications of the time/frequency resources, and switch to operate in another of the SBFD or the HD mode based on the first or second indications. Another apparatus is configured to configure time/frequency locations for SBs of SBFD operations associated with SBFD modes and time/frequency resources of a HD mode, and transmit, for a UE, first indications of the time/frequency locations, or second indications of the time/frequency resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) receives an indication to use a transmission configuration indicator (TCI) state for receiving or transmitting a communication, the TCI state indicating non-serving cell information associated with a non-serving cell. The UE receives or transmits the communication based at least in part on the TCI state and a quasi co-location (QCL) chain rule applied for the TCI state that indicates the non-serving cell information. The QCL chain rule may indicate that a synchronization signal block (SSB) of the non-serving cell as a source reference signal provides QCL information for one or more signals of a first cell and that the one or more signals of the first cell as source reference signals provide QCL information for one or more channels or signals of a second cell. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) transmission that indicates a unified transmission configuration indicator (TCI), wherein the DCI transmission comprises a semi-persistent scheduling (SPS)-release DCI transmission releasing an SPS physical downlink shared channel (PDSCH) configuration. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK codebook, wherein the HARQ-ACK feedback comprises an acknowledgment (ACK) to indicate successful reception of the unified TCI in the DCI transmission or a negative acknowledgement (NACK) to indicate a failed reception of the unified TCI in the DCI transmission. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for determining an energy per resource element (EPRE) ratio for non-zero power (NZP) channel state information reference signals (CSI-RSs) when a device is measuring a wireless channel. A method that may be performed by a user equipment (UE) includes determining, based on an indication, an energy per resource element (EPRE) ratio for a non-zero power (NZP) channel state information reference signal (CSI-RS) resource; and measuring a channel based on the determined EPRE ratio and CSI-RS s associated with the NZP CSI-RS resource.
