Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message indicating a configured grant-small data transfer (CG-SDT) group that includes the UE. The CG-SDT group is associated with a downlink beam of the base station and one or more CG-SDT occasions. The UE may transmit, to the base station and within the one or more CG-SDT occasions, an uplink communication, using an uplink beam of the UE corresponding to a downlink beam of the UE, where the downlink beam of the UE is associated with the downlink beam of the base station used for transmitting at least one of the configuration message, a paging message, or a reference signal. 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, from a base station in a full duplex mode, a first downlink transmission associated with a spatial filter. The UE may decode the first downlink transmission according to a default transmission configuration indicator (TCI) state that indicates the spatial filter. The default TCI state may be based at least in part on a first active TCI state for the full duplex mode. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for a first DL transmission on a first downlink (DL) resource on a carrier, the first DL resource being at a first frequency. The first DL resource may be at a first frequency. The first Tx power may have a power level configured based on a difference between the first frequency for the first DL resource and an uplink (UL) frequency region of the carrier. Then, the base station may transmit the first DL transmission using the first frequency and the first Tx power. Other aspects, embodiments, and features are also claimed and described.
