Abstract: Aspects relate to coordination of communication links associated with multiple subscriptions. For example, a base station may determine that a first communication link and a second communication link are established with a user equipment (UE) using a first subscription and a second subscription of the UE, respectively. At least one of the first communication link or the second communication link may be established between the UE and the base station. The base station may coordinate communication of information with the UE via at least one of the first communication link or the second communication link based on the determination. The base station may coordinate the communication of information by selecting, based on the information, one of: the first communication link and the second communication link for communicating the information, or the first communication link or the second communication link for communicating the information without utilizing the other communication link.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently identifying resources for transmitting one or more sidelink synchronization signal blocks (S-SSBs) in the shared spectrum or efficiently beam sweeping multiple S-SSBs in the shared spectrum. In one aspect, a user equipment (UE) may transmit an S-SSB in a sidelink bandwidth part (BWP) in the shared spectrum such that a lower edge of the S-SSB is aligned with or offset from a lower edge of the sidelink BWP. In another aspect, a UE may beam sweep S-SSBs in one or more S-SSB bursts in a S-SSB period to improve the chances that another UE may receive the S-SSBs. In yet another aspect, resources allocated for S-SSB transmissions may facilitate flexible S-SSB transmissions while minimizing gaps to prevent other UEs from incorrectly determining that a sidelink BWP in a shared spectrum is clear for transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relay user equipment (UE) establishes a sidelink with a remote UE to provide one or more UE-to-network relay services to the remote UE, monitors paging occasions (POs) in a first bandwidth part (BWP), receives a page from a serving base station during a PO in the first BWP, and forwards the page to the remote UE over the sidelink in an initial sidelink BWP. In another aspect, the relay UE receives downlink control information (DCI) from a serving base station for a downlink grant for the remote UE, receives downlink data for the remote UE from the serving base station, transmits sidelink control information (SCI) instructing the remote UE to switch from a first sidelink BWP to a second sidelink BWP, and forwards the downlink data to the remote UE over the second sidelink BWP of the sidelink.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications, for example, in unlicensed frequency bands. In some cases, a UE may log information associated with channel access failures on one or more frequency bands in shared spectrum and provide the information to a network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a configuration of sidelink synchronization signal block instances including a first quantity of sidelink synchronization signal block instances for each of a plurality of sidelink synchronization signal block periods. The UE may transmit a second quantity of sidelink synchronization signal block instances over a first sidelink synchronization signal block period. In some aspects, the UE may transmit a sidelink synchronization signal block burst using beams in a sidelink synchronization signal block period. The UE may identify a configuration for a set of resources of a sidelink beam selection resource pool based on transmitting the sidelink synchronization signal block burst. The UE may receive, from another UE over the set of resources, a control message including an indication of preferred beams. The UE may transmit the sidelink data to the other UE using the preferred beams.

Abstract: Certain aspects of the present disclosure provide techniques for paging in sidelink L2 relay scenarios. An example method generally includes connecting, via a sidelink, to a relay user equipment (UE) connected to a network entity; receiving, from a network entity via the relay UE, configuration information identifying a paging mode for the remote UE; and monitoring for paging from the network entity, in accordance with the identified paging mode.

Abstract: Certain aspects of the present disclosure provide techniques for system acquisition in sidelink relay scenarios. An example method for adaptive paging by a relay node generally includes connecting, via a sidelink, to a remote user equipment (UE) while the relay node is also connected to a network entity, receiving, from the network entity, system information block (SIB) information, and sending the SIB information to at least the remote UE.

Abstract: 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.

Abstract: Wireless communications systems and methods related to use of cyclic prefix (CP) extensions for channel occupancy time (COT) sharing among sidelink user equipment devices (UEs) are provided. A first UE detects a first sidelink transmission in a COT, the COT for sharing with multiple sidelink UEs including the first sidelink UE. The first UE may determine a CP extension length for transmitting a second sidelink transmission after the first sidelink transmission, where a gap duration between the first sidelink transmission and the second sidelink transmission satisfies a listen-before-talk (LBT) gap time threshold. The first UE may apply a CP extension having the CP extension length to the second sidelink transmission and transmit, to a second sidelink UE, the second sidelink transmission with the CP extension.
