Abstract: Certain aspects of the present disclosure provide techniques for configuring user equipment (UE) beam switching in multiple transmission/reception points (multi-TRPs) communications. In particular, the present disclosure provides techniques for harmonizing downlink panel switching and uplink panel switching using transmission configuration indicator (TCI) codepoints, such that in some cases, a single downlink control information (DCI) may convey multiple TCI states for multiple panels or multi-TRPs. For example, a UE receives a first DCI indicating a first TCI codepoint from TCI codepoints activated by a media access control (MAC) control element (CE). The UE receives a second DCI scheduling an uplink transmission from the UE or a downlink transmission to the UE and conveying panel switching information. The UE processes the scheduled uplink transmission and/or downlink transmission based on one or more (joint) TCI states mapped to the first TCI codepoint and the panel switching information (e.g., dynamic switching bits).

Abstract: A configuration for dummy indications in DCI with a unified TCI indication. The apparatus receives, from a base station, DCI indicating a unified TCI state of a plurality of unified TCI states for one or more channels and a dummy indication related to a TCI indication field and a PDSCH schedule. The apparatus determines an action in response to the dummy indication. The apparatus communicates with the base station based on the action determined in response to the dummy indication. The apparatus, to determine the action in response to the dummy indication, may maintain the unified TCI state for the one or more channels based on the TCI indication field of the dummy indication.

Abstract: The aspects described herein may improve beam management at an apparatus (e.g., a UE) by allowing the apparatus to proactively transmit a beam report including information that may avoid a full beam failure recovery (BFR) procedure at the apparatus. The apparatus receives a set of beam failure detection reference signals and transmits a beam report indicating a partial beam failure when a radio link quality of at least a first beam failure detection reference signal in the set of beam failure detection reference signals is less than a quality threshold and a radio link quality of at least a second beam failure detection reference signal in the set of beam failure detection reference signals is greater than or equal to the quality threshold.

Abstract: Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include receiving, from a base station, at least one of a scheduling request (SR) configuration to indicate a request for a beam switch or a physical random access channel (PRACH) configuration representing a set of PRACH resources to indicate the request for the beam switch. The example method may further include transmitting, to the base station, a PRACH or an SR in a physical uplink control channel (PUCCH) that indicates the request for the beam switch for one or more downlink (DL) or uplink (UL) channels.

Abstract: Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include transmitting, to a base station, a channel state information (CSI) report associated with a beam switch. The example method may further include performing the beam switch based on the CSI report and an absence, for a period of time after transmission of the CSI report, of a downlink control information (DCI) including a transmission configuration indicator (TCI) indication.

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: 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.
