Abstract: Methods, systems, and devices for wireless communications are described that provide for determination of timing for application of a beam based on a beam switch indication and a switch of a bandwidth part (BWP) of a frequency bandwidth that is used for communications between a user equipment (UE) and a network entity. A UE may receive a beam switch indication to switch beamformed wireless communications from a first beam to a second beam. The UE may also determine that a BWP switch is to be performed prior to using the second beam, and may use the second beam and the new BWP based on a beam application time associated with the second beam, where the beam application time is based on a channel parameter (e.g., a sub-carrier spacing) of the first bandwidth part or the second bandwidth part.

Abstract: In some implementations, a user equipment (UE) may transmit, to a network entity, a report associated with a UE capability for supporting a common timing advance (TA) configuration, wherein the report indicates one or more of: a supported TA type that includes one of an independent TA or a common TA; or a quantity of timing advance groups (TAGs) for a carrier aggregation. The UE may receive, from the network entity, a TA configuration based at least in part on the report.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving a first control information message indicating a first transmission configuration indicator (TCI) codepoint mapped to one or more first TCI states. Additionally, the first control information message may activate a set of periodic occasions for communications with a first transmission and reception point (TRP), a second TRP, or both. After some time, the UE may receive a second control information message indicating a second TCI codepoint mapped to a single second unified TCI state and select a unified TCI state from the one or more first unified TCI states or the single second unified TCI state to apply to at least a portion of the communications.

Abstract: Apparatus, methods, and computer program products for dynamic switching between different UL timings for mDCI mTRP are provided. An example method may include receiving, from a network entity, a first timing advance (TA) group (TAG) configuration. The example method may further include receiving, from the network entity, a second TAG configuration. The example method may further include applying the first TAG configuration or the second TAG configuration based on a dynamic switch configuration representing a UL transmission alignment or non-alignment for a first TRP associated with the network entity or a second TRP associated with the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate, based at least in part on a multi-downlink control information (DCI)-based multi-transmit-receive-point (mTRP) configuration, with a first TRP in accordance with a first value, associated with the first TRP, of a timing parameter. The UE may communicate, based at least in part on the multi-DCI-based mTRP configuration, with a second TRP in accordance with a second value, associated with the second TRP, of the timing parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described for configuration of multiple transmission configuration indicator (TCI) states and selection of a particular TCI state or TCI states for different instances of scheduled periodic communications between a user equipment (UE) and one or more transmission-reception points (TRPs) or base stations. A UE may receive, from a network entity, control signaling identifying two or more TCI states that are to be applied to communications of one or more channels subsequent to a determined time. The network entity may also provide a periodic communication configuration with a series of resource allocations for periodic communications, and a selection indication for which of the two or more TCI states are to be selected for the periodic communications. The UE may communicate via the one or more channels according to one or more TCI states based on the selection indication.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a HARQ codebook for multi-TB transmission. A UE may receive, from a base station, DCI including at least one of a DAI indicator or a TB counter indicator, such that the UE may determine, based on the at least one of the DAI indicator or the TB counter indicator, a number of ACK/NACK bits for the HARQ codebook. The UE may transmit, to the base station, the HARQ codebook including the determined number of ACK/NACK bits.
