Abstract: Methods, systems, and devices for identification reinterpretation in sidelink control information (SCI) are described. A first user equipment (UE) may transmit to a second UE or device, on a sidelink channel, SCI. The SCI may include a partial source and destination identifier fields and may indicate to the second UE to apply a first interpretation of multiple different interpretations for the partial source identifier field and the partial destination identifier field. For example, the SCI may indicate to interpret the partial source identifier field and the partial destination identifier field in combination as a source identifier field, as a destination identifier field, or as a partial source identifier and a partial destination identifier. The UE may transmit a medium access control (MAC) packet including a MAC header with identifier fields set to be complementary to the SCI.

Abstract: A configuration for an originating wireless device to transmit one or more MAC-CEs, where each of the one or more MAC-CEs include information related to the number of MAC-CEs transmitted. The apparatus transmits at least one of a plurality of related MAC-CEs to a second wireless device based on a determination of at least a first path of a plurality of paths to transmit the at least one of the plurality of related MAC-CEs. The at least one of the plurality of related MAC-CEs indicates a number of the plurality of related MAC-CEs transmitted by the first wireless device. The apparatus monitors for a response MAC-CE from the second wireless device based on a transmission of the at least one of the plurality of related MAC-CEs. The response MAC-CE corresponds to an activation of the MAC-CE transmitted to the second wireless device.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving base station, a medium access control control element (MAC-CE) indicating activation or deactivation of a semi-persistent (SP) sounding reference signal (SRS)-for-positioning, wherein a reserved bit in the MAC-CE or a logical channel identifier (LCID) of a MAC subheader of the MAC-CE indicates the activation or deactivation of the SP SRS-for-positioning, and transmits the SP SRS-for-positioning on one or more SRS resources configured for the UE, the SP SRS-for-positioning having transmission parameters adopted from a spatial relation reference signal for the SP SRS-for-positioning.

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: A base station may transmit downlink control information messages (DCIs) that schedule multiple physical downlink shared channels (PDSCHs) in a single DCI (multi-PDSCH DCIs) to a UE. The base station may generate DCIs with multiple downlink association index (DAI) bitwidths. The base station generate a given DCI with a DAI bitwidth based on a DCI format of the DCI, based on whether the DCI is a multi-PDSCH DCI, based on a carrier that the DCI is transmitted on, or whether the base station is capable of scheduling the UE with multi-PDSCH DCIs in general. The UE may determine the DAI bitwidth of received DCIs and may determine whether any DCIs were missed based on the DAI and the bitwidth of the DAI.

Abstract: Certain aspects of the present disclosure provide techniques for network-assisted sidelink beam failure recovery. In certain aspects, a method performed by a base station may generally include receiving from a first UE a sidelink beam failure recovery (BFR) signal, indicating that a first communication link between the first UE and a second UE has failed; determining, based on the sidelink BFR signal, a set of resources for performing a sidelink beam failure recovery procedure to reestablish the first communication link between the first UE and the second UE; and transmitting information to the first UE and the second UE indicating the set of resources for performing the sidelink beam failure recovery procedure.

Abstract: A positioning signal processing method at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode, during which the user equipment is in an active mode monitoring for a positioning signal measurement trigger signal, and OFF times of the discontinuous reception mode, during which the user equipment is in an inactive mode; receiving a wake-up signal at the user equipment; and determining, at the user equipment, whether to measure a positioning signal based on whether the wake-up signal indicates to implement the active mode during a scheduled discontinuous reception mode ON time or to skip the scheduled discontinuous reception mode ON time.

Abstract: Aspects relate to a relay device detecting a change in a protocol data unit (PDU) session configuration that the relay device has established for a user equipment (UE) that accesses a network via the relay device. Upon detecting this change, the relay device signals an indication of the change to the UE. Aspects also relate to UE that is connected to a relay device and that reselects an interworking function (e.g., a non-3rd Generation Partnership Project interworking function (N3IWF)). In some examples, the UE receives an indication from the relay device that a serving relay PDU session configuration has changed and, in response, the UE selects a new interworking function.
