Abstract: Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.

Abstract: Certain aspects of the present disclosure provide techniques for detecting a potential collision between a scheduled uplink transmission and a synchronization signal block (SSB) and transmitting the scheduled uplink transmission. For example, in cases of inter-cell multi-transmission and reception points (multi-TRP), a user equipment (UE) may not be capable of simultaneously transmitting and receiving on the multiple serving cells. A first serving cell may indicate to the UE of SSB indices that are actually transmitted for a second serving cell. If there is a slot collision between one of the SSB to be transmitted and a scheduled uplink transmission, the UE may not be able to handle such collision. The present disclosure provides techniques for detecting a potential collision between a scheduled uplink transmission and one of the SSBs and transmitting the scheduled uplink transmission when one or more conditions are met.

Abstract: Method and apparatus for a unified TCI for DCI format 1_2. The apparatus receives an activation of a first number of activated TCI codepoints. The apparatus receives a DCI comprising one or more bits that indicate a TCI state associated with at least one DCI format. The one or more bits support a second number of codepoints that is less than the first number of activated TCI codepoints. The apparatus interprets the TCI state indicated by the one or more bits based on a type of the at least one DCI format and the second number of codepoints being less than the first number of activated TCI codepoints. The apparatus communicates based on an interpretation of the TCI state in the DCI

Abstract: Certain aspects of the present disclosure provide techniques for method for wireless communications by a user equipment (UE), generally including receiving, from a network entity, a configuration of one or more sounding reference signals (SRS) resources for codebook-based physical uplink shared channel (PUSCH) transmissions, transmitting a report indicating a capability index associated with at least one downlink reference signal, transmitting the one or more of the SRS resources with an updated number of SRS ports associated with the capability index, if spatial relation information of the one or more of the SRS resources is associated with the downlink reference signal, receiving, from the network entity, signaling scheduling the UE to transmit a PUSCH based on one of the SRS resources, and transmitting the PUSCH with a number of PUSCH ports according to the updated number of SRS ports.

Abstract: Certain aspects of the present disclosure provide techniques for indicating and determining whether one or more of multiple uplink transmissions scheduled by a common downlink control information (DCI) are based on a channel occupancy time (COT) initiated by the UE, a COT initiated by the network entity, or a combination of COTs initiated by the UE and network entity. The determination may be based on a direct indication in the DCI for one or more of the multiple uplink transmissions. The determination may also be based on determining the type of COT for the remaining uplink transmissions not directly indicated by the DCI. For example, the DCI may indicate a COT type for only a first one of the multiple uplink transmissions and the UE determines a COT type for the remaining uplink transmissions based on various conditions and criteria.

Abstract: In a method of wireless communication, a user equipment (UE) receives, from a base station (BS) in a first fixed frame period (FFP), downlink communication information (DCI), where the DCI indicates a scheduled uplink (UL) communication in a second FFP subsequent to the first FFP. The UE monitors for a downlink (DL) signal in the second FFP, and transmits, to the BS based on the monitoring and a first parameter indicating whether the scheduled UL communication is associated with a BS channel occupancy time (COT) or a UE COT, the scheduled UL communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect failure of a beam, where the beam is one of a first beam associated with a first transmit receive point (TRP) or a second beam associated with a second TRP. The UE may transmit a recovery request that indicates a new beam for a beam reset by the UE, where the new beam is associated with a first group of physical uplink control channel (PUCCH) resources for the first TRP if the beam is the first beam, or associated with a second group of PUCCH resources for the second TRP if the beam is the second beam. The UE may reset the UE to the new beam after receiving a response to the recovery request. Numerous other aspects are described.

Abstract: A UE receives, from a network node, a configuration for two uplink (UL) transmissions on a component carrier (CC); and transmits, to the network node and in response to at least one power headroom report (PHR) transmission condition, an indication that corresponds to two maximum permissible exposure (MPE) values associated with at least two sounding reference signal (SRS) resource sets, respectively, for the one or more simultaneous UL transmissions on the CC. The UE receives, from a network node, a configuration for a set of MPE indication parameters that is associated with a first MPE resource pool and a second MPE resource pool at the UE; and transmits, to the network node, an indication of values for the set of MPE indication parameters associated with the first MPE resource pool and the second MPE resource pool.
