In some aspects, a user equipment (UE) may transmit, and a network node may receive, capability information that indicates whether the UE supports Layer 1 or Layer 2 (L1/L2) inter-cell mobility. The network node may transmit, and the UE may receive, radio resource control signaling configuring one or more cells for L1/L2 inter-cell mobility based at least in part on the capability information. The network node may transmit, and the UE may receive, L1/L2 signaling triggering inter-cell mobility based at least in part on the capability information indicating that the UE supports L1/L2 inter-cell mobility. 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 to switch from a first transmission configuration indicator (TCI) state associated with a first cell to a second TCI state associated with a second cell. The UE may apply the second TCI state, including switching from a first bandwidth part (BWP) associated with the first cell to a second BWP associated with the second cell. For example, the UE may receive an indication to switch from the first BWP to the second BWP. Additionally, or alternatively, the UE may determine to switch from the first BWP to the second BWP based at least in part on the indication to switch from the first TCI state to the second TCI state. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive an indication of a configuration of one or more communication links associated with an enhanced duplex mode of at least one of the first wireless node or a second wireless node. The first wireless node may receive an indication of a random access channel (RACH) configuration associated with the second wireless node. The first wireless node may transmit a request to modify the RACH configuration, where the request to modify the RACH configuration is based at least in part on the configuration of the one or more communication links and the RACH configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for selecting a default beam for communications between a user equipment (UE) and network entity on a physical downlink shared channel (PDSCH). An example method generally includes receiving, from a network entity, configuration information, selecting a default beam based on the configuration information, wherein the default beam is selected for use across a plurality of time periods, and receiving a physical downlink shared channel (PDSCH) using the default beam across the plurality of time periods.

Abstract: Aspects described herein relate to beam sweep based semi-persistent signaling (SPS) or configured grant (CG) activation. In one aspect, a network entity may determine a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission. The network entity may further transmit an indication including the beam sweep pattern to a user equipment (UE). In another aspect, a UE may receive a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission from a network entity.

Abstract: Aspects relate to mechanisms for wireless communication devices to signal for dynamically updating the configuration of a sound reference signal (SRS) resource set. A user equipment (UE) receives from a base station, via at least one of a downlink control information (DCI) or a medium access control (MAC) control element (MAC-CE), a configuration of one or more sounding reference signal (SRS) resource sets for SRS transmission. The UE also receives an indication of an update of one or more parameters, via at least one of the DCI or the MAC-CE, for at least one SRS resource set of the one or more SRS resource sets. The UE further applies the update to at least one SRS transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station, a synchronization signal block (SSB) based at least in part on a determination that the SSB is included in a timing advance group (TAG) that includes a first subset of SSBs of a first set of SSBs associated with the first base station and a second subset of SSBs of a second set of SSBs associated with a second base station. The UE may communicate with the first base station based at least in part on the SSB. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for indicating an overlap of downlink transmissions with one or more random access channel occasions (ROs). A method that may be performed by a user equipment (UE) includes receiving signaling from a base station (BS) including an indication of whether one or more ROs will overlap with downlink transmissions in one or more periods of time, transmitting, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, and performing a RACH procedure with the BS based on the transmitted RACH preamble.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a configuration indicating whether a beam switching gap is expected at a first symbol position within a subframe of a physical channel for the UE, the first symbol position having a first cyclic prefix length that is longer than a second cyclic prefix length of a second symbol position within the subframe of the physical channel for the UE. The UE may determine whether a transmission includes a missing symbol for the beam switching gap based on the configuration and the symbol position of a symbol where a beam switch is scheduled.
