Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an association between multiple phase tracking reference signal (PTRS) ports and multiple codewords that are to be used for an uplink communication that uses multiple antenna port groups, and transmit the uplink communication using the multiple codewords based at least in part on the association. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for reallocating padded acknowledgment resources. A user equipment (UE) may be configured to use resources allocated for acknowledgment feedback that may be otherwise associated with padded feedback bits for additional reporting bits. For example, if acknowledgment feedback includes at least one positive acknowledgment (ACK) bit, the UE may replace (for example, reallocate) one or more padded feedback bits with additional reporting bits. If the UE is unable to receive an instance of downlink control information (DCI), or if the UE unsuccessfully receives or decodes each scheduling unit scheduled by an instance of DCI, the UE may maintain padded feedback bits acknowledgment feedback. In various implementations, additional reporting bits may indicate one or more of a power headroom (PH) value, a modulation and coding scheme (MCS), a preferred beam configuration, or a maximum permissible exposure (MPE) value.

Abstract: To facilitate TCI state update and activation to provide common QCL information, methods, apparatuses, and computer-readable storage medium are provided. An example method includes transmitting, to a base station, an indication of a UE capability associated with a unified transmission configuration indicator (TCI) indication to one or more reference signals (RSs). The example method further includes communicating with the base station based in part on the UE capability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that beam switching without an explicit beam indication or activation is allowed. The UE may transmit a channel state information (CSI) report identifying a selected beam. The UE may selectively switch to the selected beam in accordance with the indication. Numerous other aspects are described.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for downlink control information format for indication of transmission configuration indication state. A user equipment may receive, from a base station, downlink control information (DCI); determining whether the DCI is used for beam indication with or without downlink assignment. The UE also may apply transmission configuration indication (TCI) states based on TCI codepoints in a TCI field of the DCI, when the DCI is used for beam indication. The base station may generate the DCI with information indicating whether the DCI is intended for beam indication with or without downlink assignment, in which the DCI includes the TCI codepoints to apply the TCI states at the UE when the information in the DCI indicates that the DCI is intended for beam indication. The base station may transmit, to the UE, the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam applicability report that indicates beam applicability information corresponding to one or more physical channels for a UE cooperation operation. The UE may communicate with at least one wireless communication device in the UE cooperation operation based at least in part on the beam applicability information. 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 generate a medium access control control element (MAC-CE) that indicates a power headroom level for each panel of multiple panels of the UE, which is configured for multi-panel operation. The UE may transmit the MAC-CE. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) to transmit a joint channel state information (CSI) report for both uplink beams and downlink beams and for a base station (BS) to receive the joint CSI report. The BS may configure the UE to measure metrics based on CSI reference signals (RS) or synchronization signal blocks (SSB). The UE may measure the CSI-RS or SSB to determine CSI metrics including at least one downlink metric and at least one uplink metric for at least one set of uplink panel identifiers (IDs). The UE may transmit the joint CSI report including the at least one downlink metric, the at least one uplink metric, and the set of uplink panel IDs associated with the at least one uplink metric.

Abstract: A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive, from a base station, a transmission configuration indication (TCI) including a global TCI state pool, the global TCI state pool including at least a first TCI state list corresponding to a physical channel, and configure the UE based on the first TCI state list. Further, the user equipment may determine channel information for the physical channel based on the configuring and a reference signal.
