    Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure one or more UEs for single frequency network (SFN) communications that provide concurrent communications with a first transmission-reception point (TRP) and a second TRP in a first active bandwidth part (BWP) using a first uplink carrier. In cases where the SFN configuration does not provide an indication of a spatial relation or a path loss reference signal that is associated with the first active BWP, the UE and the TRPs may determine an associated first spatial relation or first path loss reference signal for the SFN communications based at least in part on the first active BWP and the SFN configuration. The UE may transmit uplink SFN communications to one or more TRPs using a beam that is determined based on the first spatial relation or first path loss reference signal.

    Abstract: Methods, systems, and devices for wireless communications are described in which frequency selective precoding may be used for wireless transmissions. A transmitting device, such as a user equipment (UE), may have a set of allocated resources that include time domain resources and frequency domain resources, and different precoding may be applied to different portions of the frequency domain resources. The different precoding may be indicated in a resource grant that indicates multiple precoders that that are associated with different portions of frequency domain resources, such as different precoders that are associated with different reference signal resources sets that are associated with portions of the frequency domain resources. The indication of multiple precoders may be provided with an uplink grant to a UE that is associated with a single antenna panel at the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. A UE may cooperate with a group of one or more other UEs, where the UEs may each operate as a panel in a wireless communications system. To ensure updated information based on the cooperation status of the UE is provided to a network, the UE may receive one or more capability request messages from a base station. The UE may determine a group cooperation capability of the UE, based on a current group cooperation status of the UE. The group cooperation status may be based on the UE operating in cooperation with a group of UEs for communicating with the base station. The UE may then transmit, to the base station, one or more messages indicating the group cooperation capability of the UE.

    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.
