Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message (e.g., downlink control information (DCI), radio resource control) indicating a configuration for a signal, where the configuration may indicates whether the signal is associated with one or more unified transmission configuration indicator (TCI) states of a selected unified TCI codepoint. The UE may receive a first DCI message indicating a set of one or more activated TCI codepoints that are each associated with one or more TCI states, and receive a second DCI message indicating the selected unified TCI codepoint from the set of one or more activated TCI codepoints. The UE may apply a TCI state for communication of the signal in accordance with the configuration.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may be configured to support uplink power control for multiple random access channel (RACH) procedures. A medium access control layer entity at the UE may maintain multiple sets of counters and parameters for multiple simultaneous RACH procedures. In some cases, the UE may perform simultaneous RACH procedures with network entities associated with different timing advance groups, and the UE may associate the counters and parameters of the RACH procedure with the timing advance group. In other cases, the UE may associate the counters and parameters of the RACH procedure with multiple control resource set pool indexes which may correspond to multiple transmission reception points. Each set of counters may be associated with an uplink power control that the UE may use to determine the PRACH transmission power for each RACH procedure.

Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a multi-device aggregation (MDA) indication from a network entity. The MDA indication indicates an inclusion of the first UE in an aggregation of multiple UEs associated with an object. The UE then performs, based on the aggregation of the multiple UEs, an MDA operation via a physical (PHY) or medium access control (MAC) layer shared among the multiple UEs. The MDA operation includes one or more of beam management, channel state information (CSI) measurement or reporting, radio resource management (RRM), cell selection or reselection, or a positioning operation.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a user equipment (UE) may receive control information from a network entity that includes a configuration for self-interference channel state information (CSI) measurements and self-interference CSI reporting. The control information may additionally include configurations for interference measurements other than self-interference. The UE may perform one or more self-interference CSI measurements and other CSI measurements based on receiving the control information. In some examples, the one or more self-interference CSI measurements may be associated with one or more subbands based on the configuration for self-interference CSI measurements. The UE may transmit one or more CSI reports, including one or more CSI reports associated with self-interference, to a network entity based on performing the one or more CSI measurements.

Abstract: Method and apparatus for PUSCH selection for UCI multiplexing. The apparatus determines that a transmission of UCI would at least partially overlap in time with transmissions of a set of PUSCHs. The set of PUSCHs including a plurality of PUSCHs on a same CC that are at least partially overlapping in time. The apparatus selects one PUSCH of the set of PUSCHs for multiplexing the UCI. The selection of the one PUSCH being based at least partially on a group association between the UCI and each PUSCH of the set of PUSCHs, or one or more transmission parameters of each PUSCH of the plurality of PUSCHs. The apparatus multiplexes the UCI on the selected one PUSCH for simultaneous transmission.
