    Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate to Layer 1 or Layer 2 triggered mobility (LTM) using groups of candidate cells. Some aspects more specifically relate to performing LTM operations, such as measurement, reporting, or switching, for cells of an activated group of candidate cells for LTM. In some aspects, a user equipment (UE) may measure an activated group of candidate cells in accordance with the activated group of candidate cells being activated. For example, the UE may not measure candidate cells that do not belong to an activated group of candidate cells. In some aspects, the activated group of candidate cells may include a subset of all candidate cells configured for the UE. For example, the UE may perform measurement and reporting for the subset of candidate cells, instead of all candidate cells configured for the UE.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication, configuration, or adaptation of a triggering condition. The UE may evaluate a performance effect based, at least in part, on the triggering condition. The UE may initiate a handover procedure from a source cell to a target cell based, at least in part, on the performance effect. 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 configuration information that configures measurement of multiple candidate cells associated with a layer 1/layer 2 triggered mobility procedure. The UE may perform measurements associated with the multiple candidate cells based at least in part on the configuration information. The UE may transmit a layer 1 measurement report that reports the measurements associated with the multiple candidate cells based at least in part on differential reporting. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access channel (RACH) message to a first distributed unit (DU) via a cell supported by the first DU to support acquisition of timing advance (TA) information prior to switching to the cell. A second DU serving the UE may identify and indicate the TA information to the UE based on the UE transmitting the RACH message indicating a RACH preamble allocated to the second DU by a central unit (CU). The RACH preamble may be included in a set of preambles indicated to the CU by the first DU for TA information acquisition. Alternatively, the UE may be identified by the first DU based on a UE-specific RACH preamble, a RACH preamble, RACH occasion (RO) pair, or a request by the second DU to order the UE to transmit the RACH message.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication and more particularly to hybrid measurements and reporting for Layer 1 (L1)/Layer 2 (L2) triggered mobility (LTM). Some aspects more specifically relate to a UE performing filtered measurements of one or more LTM candidate cells. In some aspects, the hybrid measurements and reporting may be associated with measurements using Layer 3 type measurements and reporting using L1 type reports for LTM. In some aspects, one or more cells, from the one or more LTM candidate cells, may be selected (for example, by the UE or by a network node) for L1 measurement or reporting associated with the filtered measurement values. In some aspects, the UE may transmit an L1 measurement report indicating L1 measurement values of the one or more cells. A network node may perform one or more operations in response to the L1 measurement values.
