Abstract: Aspects of the disclosure relate to establishing connections between a user equipment (UE) and a base station via a communication link using multiple subscriptions. In an aspect, a UE configured to communicate using a first subscription and a second subscription may establish a first connection with a base station via a communication link using the first subscription of the UE and may establish a second connection with the base station via the communication link using the second subscription of the UE. The UE may further perform a second connection with the base station via the communication link using the second subscription of the UE.

Abstract: An apparatus is provided to perform listen before talk failure recovery and cancel a recovery response based on a trigger. The apparatus may monitor for a consistent listen before talk (LBT) failure for an uplink transmission to a base station, determine whether to perform a LBT recovery response based on the monitoring, detect a trigger, and cancel the LBT recovery response or resetting the monitoring based on the trigger.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for semi-persistent scheduling (SPS) and hybrid automatic repeat request (HARQ) feedback skipping for user equipment (UE)-initiated transmissions. A UE configured for extended reality (XR) operations and an SPS configuration including a plurality of SPS occasions, each SPS occasion configured with at least one downlink resource and at least one uplink resource, collects pose information related to at least one SPS occasion. The UE determines, based on the pose information, to skip at least one SPS occasion. The UE sends an indication of the determination to skip the at least one SPS occasion to a base station. The indication is transmitted in a preconfigured uplink resource or may be piggybacked in an uplink transmission. The base station may reallocate the resources configured for the at least one SPS occasion based on receiving the indication.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive a multi-opportunity grant from a network entity, the multi-opportunity grant indicating multiple listen-before-talk (LBT) opportunities for scheduling a transmission between the first UE and a second UE; perform a LBT procedure for one or more slots of a plurality of slots indicated by the multiple LBT opportunities; select a first slot of the plurality of slots corresponding to an earliest available LBT based on performing the LBT procedure; and communicate a transmission to the second UE during the transmission time interval (TTI) of the first slot.

Abstract: Methods, systems, and devices for wireless communications are described to enable abase station and a user equipment (UE) to identify and respond to communications in accordance with one or more communications services. For example, the base station and the UE may support communications in accordance with a wireless communications standard (e.g., third generation partnership project (3GPP) standard), in addition to supporting an additional communications service including one or more proprietary features. In some cases, the UE may transmit an indication to the base station, or the base station may otherwise determine, that the UE supports the proprietary features. Further, the base station may assign and transmit a unique radio network temporary identifier (RNTI) to the UE for the additional communications service (e.g., a proprietary RNTI). Accordingly, the UE and the base station may identify and use the proprietary RNTI when transmitting, receiving, decoding, and responding to proprietary communications messages.

Abstract: Wireless communications systems and methods related to providing subchannel selection or recommendation and/or channel state information (CSI) for sidelink communications (e.g., operating in mode-1 radio resource allocation (RRA) via a buffer status report (BSR) are provided. A first user equipment (UE) transmits, to a base station (BS), a BSR indicating subchannel information associated with one or more UEs. The UE receives, from the BS in response to the BSR report, a grant for transmitting a first sidelink transmission to a second UE of the one or more UEs. The UE transmits, to the second UE based on the grant, the first sidelink transmission.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QoS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a resource grant for at least one sidelink channel, wherein the resource grant indicates a first uplink resource for transmitting sidelink transmission acknowledgement messages and a second uplink resource for transmitting listen-before-talk statuses. The UE may transmit, to the base station and on the second uplink resource, an indication of at least one status associated with a listen-before-talk procedure used on the at least one sidelink channel. Numerous other aspects are provided.
