Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive control signaling indicating a beam group reporting configuration including a trigger condition for reporting channel state information (CSI) associated with multiple beam groups each including multiple beams. The UE may transmit a first uplink message including an indication that the trigger condition has been satisfied, and may transmit a second uplink message including a measurement report that includes CSI associated with at least a first beam group of the multiple beam groups, the first beam group being associated with satisfaction of the trigger condition. The UE may then receive, in response to the second uplink message, additional control signaling including beam information for communications between the base station and the UE, and may communicate with the base station in accordance with the beam information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of reference signals (RSs) that are associated with a reduced activation time. The UE may receive activation signaling identifying a transmission configuration indicator (TCI) state associated with an RS, of the set of RSs, to be activated for a communication. The UE may perform the communication using the identified TCI state, wherein the identified TCI state is activated within the reduced activation time after the activation signaling is received. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an activation command for a pathloss reference signal (PLRS). The UE may estimate a pathloss using the PLRS based at least in part on an applicable time for the PLRS that indicates a time at which the PLRS is to be ready for use in estimating the pathloss. Numerous other aspects are provided.

Abstract: In accordance with some embodiments, wireless communication for transmission of a beam failure recovery (BFR) MAC-CE is disclosed. A method performed on a user equipment (UE) includes detecting a beam failure of at least one beam of a beam group. The method further comprises triggering a BFR in response to the detection of the beam failure of the at least one beam of the beam group. In addition, the method includes generating a BFR medium access control-control element (MAC-CE) that includes BFR information associated with the beam group. Further, the method comprises transmitting the BFR MAC-CE that includes the BFR information associated with the beam group using a transmission resource.

Abstract: Devices and methods for wireless communication between a scheduled entity having a plurality of antenna elements operable as multiple antenna and a scheduling entity include signaling transmission configuration information (TCI) to a scheduled entity to define unified TCI states that indicate beam directions of multiple corresponding beams, signaling a unified TCI state to be used for an upcoming communication for the scheduled entity using two or more beams as indicated by the unified TCI state.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: An apparatus, e.g., a UE, is disclosed. The apparatus may transmit, to a serving cell, UE capability information for performing L1/L2 measurements of at least one target RS received from a non-serving cell and reporting measurement information. The apparatus may receive, based on the transmitted UE capability information, a configuration including a TCI state scheduling the UE to receive the at least one target RS from the non-serving cell based on at least one source RS associated with the TCI state, and to perform the L1/L2 measurements of the at least one target RS. The number of RS reported in the measurement report may be based on at least one of a UE capability, an indication received from the serving cell, a pre-configuration, or an indication received from the serving cell in which the indication is within the UE capability.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for signaling whether to generate cross-link interference (CLI) measurement reports based on a single CLI measurement occasion or based on multiple CLI measurement occasions. A network entity may indicate whether to generate a CLI measurement report based on a single most recent CLI measurement occasion or based on CLI measured over a number of CLI measurement occasions. The measuring user equipment (UE) may generate a CLI report based on a single most recent CLI measurement occasion or based on a statistical CLI measurement based on respective CLI measurements for each respective CLI measurement occasion of the number of CLI measurement occasions depending on the indication. The network entity may also indicate to the aggressor UE to repeat transmission of sounding reference signals using the same transmit beam during the CLI measurement occasions.
