Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive configuration information, the configuration information indicating that a Layer 1 / Layer 2 (L1/L2) control signal is to be used to indicate when the network node is to: switch from additional transmission reception point (TRP) functionality to primary TRP functionality for a primary serving cell, or switch from a secondary serving cell to the primary serving cell and activate the primary TRP functionality. The network node may receive the L1/L2 control signal. The network node may activate, based at least in part on the L1/L2 control signal, the primary TRP functionality. Numerous other aspects are described.

Abstract: Aspects of the disclosure provide techniques for enabling cell synchronization and timing adjustment management in layer 1 and layer 2 (L1-L2) centric mobility applications. A user equipment (UE) communicates with a network entity using one or more cells of a plurality of cells that are configured for mobility operations using layer 1 and layer 2 (L1-L2) centric signaling. The plurality of cells are grouped into one or more timing adjustment groups (TAGs). The UE updates timing advance of the plurality of cells per group according to the one or more TAGs.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station, configuration information for a conditional handover, where the configuration information indicates an execution condition and one or more carrier aggregation configurations associated with one or more candidate base stations, and where the execution condition is based at least in part on at least one of a beam-based measurement or a cell-based measurement and at least one of special cells or secondary cells (SCells) associated with the one or more candidate base stations. The UE may transmit, to a candidate base station of the one or more candidate base stations, a message to initiate the conditional handover based at least in part on the execution condition having been satisfied. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive an indication that a transmission of first data is to be modified and that second data is to be transmitted in place of a portion of the transmission of the first data; and identify a single time at which the transmission of the first data is to be canceled and transmission of the second data can begin, based at least in part on capabilities of the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to long term sensing based inter-operator coexistence techniques for unlicensed high bands providing a measurement framework and candidate measurements, along with channel selection, per-beam channel deselection, and dynamic frequency selection. In one aspect, a network entity may determine that a non-coordinating node satisfies a communication presence threshold based on the at least one long term sensing measurement, and transmitting, to a user equipment (UE), an indication of a remedial action, or adjusting the communication channel based on the determination. In another aspect, a UE may obtain at least one long term sensing measurement, and transmit a long term sensing report including the at least one long term sensing measurement.
