Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate timing alignment factors in support of timing alignment adjustments by a base station or one or more transmission reception points (TRPs). Such timing adjustments may be in the context of cooperative beamforming and may relate to the timing with which the TRPs transmit respective instances of downlink transmissions to the UE. In some cases, the UE may report absolute timing alignment factors to support such timing alignment adjustments. Additionally or alternatively, the UE may report relative timing alignment factors, for example compared to signals received from a reference TRP, to support such timing alignment adjustments.

Abstract: This disclosure provides systems, methods and apparatuses for a selection of one or more transmission and reception points (TRPs) within a multi-TRP system. In one aspect, a user equipment (UE) may transmit an indication of the selected TRPs and an indication of one or more beams that the selected TRPs may use to communicate with the UE based on a mismatch between a default operating frequency (DOF) of each TRP within the multi-TRP system and a DOF of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the TRPs within the multi-TRP system and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select to communicate with TRPs and select one or more ports that the selected TRPs may use to communicate with the UE based on the comparison.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: A sidelink user equipment (UE) receives a group wake-up signal (WUS) from a base station and decodes the group WUS based on zone identification (ID) information of the sidelink UE. A base station transmits a wake-up signal to a group of sidelink user equipments (UEs) and transmits zone ID information to the group. A group wake-up signal parameter is a function of the zone ID information. A base station generates a demodulation reference signal (DMRS) sequence, selects a port for a DMRS, and/or scrambles a control channel or a data channel based on a zone ID of a sidelink UE. A sidelink UE compares a zone ID of the sidelink UE with a zone ID of a neighbor UE and initiates a conditional handover to another cell when the zone ID of the sidelink UE differs from the zone ID of the neighbor UE.
