Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling L1 (physical layer) and L2 (medium access control (MAC) layer) inter-cell mobility. More specifically, rules and operations performed during L1/L2 based cell handover operations. In certain aspects, a user equipment (UE) is configured to receive, from a network entity of a source cell via at least one of L1 or L2 signaling, a handover command for the UE to handover from the source cell to a target cell. The UE may determine at least one transient period during which the UE is served by both the source cell and the target cell, and perform the handover while communicating with the source cell and target cell during the transient period.

Abstract: Method and apparatus to configure a UE to initiate a two-step RACH process to perform a PCI selection process using L1/L2 messaging. The apparatus determines at least one target PCI in preparation of performing a PCI selection procedure. The apparatus selects a first target PCI that meets a threshold to initiate the PCI selection procedure. The apparatus transmits a first random access response message to the first target PCI. The apparatus monitors for a second random access response message from the first target PCI.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device may transmit a random access channel (RACH) signal using a transmit beam of a set of transmit beams. The RACH signal may include a RACH preamble. The communication device may receive, based on the transmitted RACH signal, a receive beam of a set of receive beams. The communication device may determine a level of self-interference of the received beam. For example, the communication device may measure the level of self-interference of the received beam based on the transmitted RACH signal including the RACH preamble. The communication device may operate in a mode based on the determined level of self-interference.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for reducing path loss reference signal (PL RS) application time. An example method generally includes receiving signaling indicating activation of path loss (PL) reference signals (RSs), determining that the UE can reduce an application time for using the PL RS for uplink power control purposes, wherein the reduced application time is reduced relative to a non-reduced application time, and using PL RS measurements taken according to the reduced application time for uplink power control.

Abstract: A method of wireless communication is presented. The method includes receiving, at a user equipment (UE) from a base station, a measurement configuration comprising quasi-co-location (QCL) information for a serving reception beam. The method also includes measuring cross-link interference experienced on the serving reception beam. The method further includes transmitting the QCL information for the serving reception beam and a corresponding sounding reference signal-reference signal received power (SRS-RSRP) or cross-link information-received signal strength indicator (CLI-RSSI) to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate via control signaling a switching pattern for a bandwidth part (BWP) for communication between a user equipment (UE) and the base station. The switching pattern may include a set of slots associated with a full-duplex communications mode and a set of slots associated with a half-duplex communications mode. The UE and the base station may communicate in the half-duplex communications mode using the BWP, and the UE and the base station may communicate in the full-duplex communications mode using at least one of a first sub-BWP of the BWP for uplink signaling and a second sub-BWP of the BWP for downlink signaling. The base station may configure different resource allocations, operating parameters, and physical uplink control channel resources for the same configured transmissions or receptions for the half-duplex communications mode and the full-duplex communications mode.

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.
