Aspects of the disclosure relate to a user equipment (UE) for establishing a sidelink communication channel and receive mapped channel state information-reference signals (CSI-RS) over a plurality of PSSCH resource blocks. The mapped CSI-RS may be interlaced with resource elements in at least a portion of the plurality of PSSCH resource blocks. The CSI-RS received over the plurality of PSSCH blocks is then processed to determine a channel quality of the sidelink channel from the portion of the plurality of PSSCH resource blocks including the mapped CSI-RS.

Interlaced sidelink data for communication

Methods, systems, and devices for wireless communications are described. The method includes a user equipment (UE) receiving signaling from a network entity that indicates a set of multiple node configurations for a set of multiple target nodes, receiving a command from the network entity to perform a node update procedure associated with the set of multiple node configurations, performing the node update procedure based on receiving the command, maintaining at least one of the set of multiple node configurations after performing the node update procedure, and communicating based on results of the node update procedure.

Maintaining configurations in conditional primary secondary cell group change

Aspects of the disclosure relate to mechanisms for enhancement in UE cell selection to prioritize cells supporting 5G New Radio (NR) in standalone mode (SA) and in non-standalone (NSA) mode. In some examples, a UE may identify a plurality of cells within an area including a location of the UE. Each cell supports at least one radio access technology (RAT) and at least one frequency. The UE may determine a selection order of the plurality of cells based on the supported RATs and frequency bands to prioritize cells supporting the latest RAT (e.g., 5G NR) and select a serving cell based on the selection order.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a radio resource control (RRC) setup procedure for a first subscriber identity module (SIM) of the UE and transmit a serving temporary mobile subscriber identity of the first SIM in association with an RRC setup procedure for a second SIM. Numerous other aspects are provided.

Association of multiple subscriber identity modules

Methods, systems, and devices for wireless communications are described that provide for interference-aware beam failure detection procedures. One or more beam failure parameters may be adjusted based on a likelihood of temporary interference being present for a communications beam. The beam failure parameters may include beam failure indication (BFI) counts or count thresholds that may be adjusted based on a likelihood of BFIs being the result of temporary interference. Additionally or alternatively, one or more measurement thresholds that trigger a BFI may be adjusted based on a likelihood of a presence of temporary interference.

Techniques for interference-based beam failure detection

Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive, from a network entity, a first sidelink grant for a transmission between the first UE and a second UE; communicate the transmission according to the first sidelink grant to the second UE; determine initiation of a sidelink round trip timer subsequent to communicating the transmission to the second UE; and initiate an inactive mode for the first UE based on a second grant not being received from the network entity before completion of a duration of a sidelink retransmission timer that was initiated upon completion of a duration of the sidelink round trip timer, the first UE being configured out of an ON duration of a discontinuous reception (DRX) cycle, and an inactivity timer expiring before completion of the duration of the sidelink retransmission timer.

Scheduling operation with mode-1 scheduling in sidelink and sidelink unlicensed operations

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a measurement configuration including trigger conditions for performance of handover procedures within a service-based wireless system. The UE may transmit a message indicating a satisfaction of a trigger condition to a source network entity, a mobility service offered by a service-based network, or both. After performance of a handover decision by the source network entity, the mobility service, or both, the mobility service may select a target network entity for the handover procedure. The mobility service may select a target network entity that supports at least one active core network service at the UE. The UE may then receive a handover command from the mobility service, and may perform a handover procedure to the target network entity.
