Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first configuration for a physical uplink control channel (PUCCH) resource set, the first configuration associated with a first configured number of symbols for a PUCCH. The UE may receive, from the base station, an indication of a number of symbols to be used for transmitting the PUCCH, the indicated number of symbols being different from the first configured number of symbols. The UE may transmit the PUCCH using the indicated number of symbols. Numerous other aspects are provided.

Abstract: An apparatus, e.g., a UE, for resolution of conflicts between HD and FD configurations is disclosed. The UE receives a configuration indicating that a first set of symbols is configured for HD communication with at least one of D symbols, U symbols, or F symbols in which the F symbols are configured as D or U. The UE receives DCI scheduling FD communication including an FD transmission and an FD reception on a second set of symbols. The second set of symbols have a third set of symbols in common with the first set of symbols. The third set of symbols have conflicting HD and FD configurations. The UE cancels, based on the conflicting HD and FD configurations of the third set of symbols, at least one of the FD transmission or the FD reception in the third set of symbols.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications. An example method generally includes calculating a first power headroom report (PHR) for a half duplex (HD) operating mode, calculating a second PHR for a full duplex (FD) operating mode during which maximum uplink transmit power is subject to one or more self-interference constraints, determining whether to report the first PHR, the second PHR, or both, and reporting at least one of the first PHR or the second PHR to a network entity, in accordance with the determination.

Abstract: Aspects of the present disclosure can be implemented in a method for wireless communication by a first wireless node, such as a user equipment (UE) or network entity. The method generally includes identifying different patterns of phase tracking reference signal (PTRS) tones for receiving a PTRS, determining when to change at least one of the different patterns of the PTRS tones from one symbol to another, and monitoring for one or more symbols of the PTRS, from a second wireless node, according to the determination.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.

Abstract: Aspects of the present disclosure can be implemented in a method for wireless communication by a first wireless node. The method generally includes receiving, from a second wireless node, information regarding PTRS tones, designating one or more of the PTRS tones as ZP tones and one or more of the PTRS tones as NZP tones based, at least in part, on the information, and transmitting a PTRS on the NZP tones. In some cases, the first wireless node is a user equipment (UE) and the second wireless node is a network entity. In some cases, the first wireless node is a network entity and the second wireless node is a UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a timing for a reference signal measurement. The UE may measure, for a secondary cell activation procedure, a reference signal based at least in part on determining the timing for the reference signal measurement. Numerous other aspects are provided.

Abstract: In operation, the UE in the cell (SpCell/SCell) may be configured to operate with beam group specific BFRs, cell-level BFRs, or combinations of them under a beam failure configuration that is determined according to various rules. A method of wireless communication performed by a user equipment (UE) and a UE is disclosed. The method includes determining a beam failure configuration for a serving cell, the beam failure configuration including at least one of a beam failure parameter of a beam group or a beam failure parameter of a cell; and detecting, in the serving cell based at least in part on the beam failure configuration, a beam failure recovery (BFR) based at least in part on the beam failure configuration. The beam failure configuration is determined based on various rules that control the operation of the BFR.

Abstract: Certain aspects of the present disclosure provide enhancements to enable per transmission reception point (per-TRP or per beam group)-based beam failure recovery, and more particularly, techniques for TRP-specific beam failure recovery request (BFRQ). A method that may be performed by a user equipment (UE) includes communicating using beams associated with at least two beam groups, each associate with one of the TRPs, detecting a beam failure in a first one of the beam groups, and transmitting an indication of a BFRQ specific to a beam group in which the beam failure was detected.
