Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a timing advance value to use for an uplink transmission based on a unified transmission configuration indicator (TCI) state associated with the uplink transmission. In some examples, the control signaling configuring a unified TCI state for an uplink transmission may indicate the timing advance value for the uplink transmission. In some examples, the UE may receive control signaling indicating an association between a set of timing advance values for the component carrier associated with a set of unified TCI states or a set of unified TCI groups, and the UE may determine the timing advance value for a given uplink transmission based on the TCI state or TCI group indicated for the uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node associated with a first transmit-receive point (TRP) identifier (ID) and a second TRP ID, an uplink repetition configuration comprising a first mapping between the first TRP ID and a first uplink repetition component and a second mapping between the second TRP ID and a second uplink repetition component. The UE may transmit a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping. The UE may transmit a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. 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 receive an indication of a pair of transmission configuration indication (TCI) states associated with a physical downlink shared channel (PDSCH). The UE may select, based at least in part on the indication, a default beam for receiving information via the PDSCH. 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 receive configuration information associated with a first sounding reference signal (SRS) resource set, including a first quantity of SRS resources, and a second SRS resource set, including a second quantity of SRS resources. The UE may receive downlink control information (DCI) scheduling a spatial division multiplexing communication, the DCI indicating a first one or more SRS resources, associated with a first set of layers, and a second one or more SRS resources, associated with a second set of layers, from the first SRS resource set and/or the second SRS resource set based on: a dynamic switching indicator, a first SRS resource indicator (SRI), a second SRI, the first quantity of SRS resources, the second quantity of SRS resources, and/or a maximum rank. Numerous other aspects are described.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or a component thereof. The apparatus may include a processing system configured to: determine a Power Management Maximum Power Reduction (P-MPR) value associated with an identifier (ID) of at least one of an antenna panel or a beam, and calculate an output power threshold associated with the ID of the at least one of the antenna panel or the beam based on the P-MPR value. The apparatus may further include a first interface configured to output data for transmission to a network node, the transmission being based on the output power threshold.

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.
