Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicative of a subband full-duplex (SBFD) configuration associated with at least one flexible time resource semi-statically configured as an SBFD time resource. The UE may apply, in association with at least one of a slot format communication or the SBFD configuration, a directionality rule to the at least one flexible time resource to establish at least one directional format of the at least one flexible time resource, the directionality rule corresponding to an uplink transmission direction or a downlink reception direction, and the slot format communication indicating a slot format update instructing the UE to update a directionality associated with the at least one flexible time resource. The UE may communicate with a network node based on the at least one directional format. 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, from a serving cell, a physical downlink control channel (PDCCH) order initiating a random access procedure in a candidate cell. The UE may determine a timing delay associated with a timing difference between the serving cell and the candidate cell. The UE may transmit a physical random access channel (PRACH) communication to the candidate cell in accordance with the PDCCH order and the timing delay. 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 a physical downlink control channel (PDCCH) order that indicates to perform a random access channel (RACH) procedure that is associated with a candidate cell and is not associated with a configured random access response (RAR), the PDCCH order indicating a retransmission state associated with a physical random access channel (PRACH) message that is associated with the candidate cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform group-based reporting based on channel measurement resource (CMR) sets corresponding to a candidate cell. In some examples, the UE may transmit a group-based beam report indicating measurements for reference signals from the candidate cell that can be simultaneously received. For example, the UE may measure signal strengths associated with one or more reference signal pairs, where each reference signal pair includes a respective first reference signal from a first CMR set and a respective second reference signal from a second CMR set.

Abstract: A network node (first cell) may identify a configuration associated with one or more resources for an L1/L2 CLI measurement associated with a CLI between a first UE and a second UE. The network node (first cell) may transmit, for the first UE, the configuration associated with the L1/L2 CLI measurement via an RRC message or a DCI message. Based on the configuration, the first UE may identify reception timing for an L1/L2 CLI measurement associated with a CLI between the first UE and a second UE. The first UE may perform the L1/L2 CLI measurement associated with the CLI between the first UE and the second UE based on the identified reception timing.

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.
