Abstract: A UE may identify, during a first DRX ON period immediately preceding an existing DRX OFF period, that a first condition is met. The UE may transmit, to a network node, and the network node may receive, from the UE, a request to extend the first DRX ON period based on the first condition being met. The network node may transmit, to the UE, and the UE may receive, from the network node, an indication of approval of the request to extend the first DRX ON period. The UE and the network node may delay a beginning of the existing DRX OFF period by a first time period based on the approval of the request to extend the first DRX ON period.

Abstract: Certain aspects of the present disclosure provide techniques for air interface and sidelink discontinuous reception alignment for inactive/idle user equipment. A method performed by a user equipment (UE) includes receiving, from a second user equipment at a first user equipment over a sidelink interface, discontinuous reception (DRX) configuration assistance information and transmitting, from the first user equipment to a network via an air interface, the DRX configuration assistance information. The method may further include receiving, from the network at the first user equipment via the air interface: modified air interface DRX configuration information for the first user equipment, and sidelink DRX configuration information for the first user equipment and the second user equipment, wherein the sidelink DRX configuration information is based on the DRX configuration assistance information; and transmitting, from the first user equipment to the second user equipment over the sidelink interface, the sidelink DRX configuration information.

Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node (e.g., a first user equipment (UE)) may determine a first sidelink discontinuous reception (DRX) priority assigned to the first network node, wherein the sidelink DRX priority is based on one or more criteria associated with the first network node. The first network node may communicate on a sidelink channel using a first set of one or more DRX configurations based on the first sidelink DRX priority assigned to the first network node, wherein the first set of one or more DRX configurations are at least partially aligned in time with a second set of one or more DRX configurations of a second network node (e.g., a second UE) assigned a second sidelink DRX priority that is equivalent to the first sidelink DRX priority. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may generate information indicating a reference signal and a measurement report for a first sidelink between the first UE and a second UE. The first UE may use the information for a second sidelink between the first UE and the second UE. Numerous other aspects are described.

Abstract: In accordance with some embodiments, wireless communication for transmission of a beam failure recovery (BFR) MAC-CE is disclosed. A method performed on a user equipment (UE) includes detecting a beam failure of at least one beam of a beam group. The method further comprises triggering a BFR in response to the detection of the beam failure of the at least one beam of the beam group. In addition, the method includes generating a BFR medium access control-control element (MAC-CE) that includes BFR information associated with the beam group. Further, the method comprises transmitting the BFR MAC-CE that includes the BFR information associated with the beam group using a transmission resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging message that indicates a set of resources corresponding to a channel state information (CSI)-reference signal (CSI-RS) associated with a plurality of refined sub-beams of a synchronization signal block (SSB) beam. The UE may transmit, in a transmission associated with a physical random access channel (PRACH), an indication of a selected sub-beam of the plurality of refined sub-beams. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may communicate (e.g., transmit, receive) a message indicating a relay UE for relaying wireless communications between the target UE and a base station. The relay UE is selected from a set of candidate relay UEs based on existing sidelink relay communication links at the relay UE, candidate target UEs associated with the relay UE, existing communication sidelinks between the target UE and the candidate relay UEs, or any combination thereof. The target UE may receive a first control signal indicating a sidelink relay communication link for communicating messages between the first UE and the base station via the relay UE, and receive a second control signal activating the sidelink relay communication link. The target UE may then communicate a message to or from the base station via the relay UE and the sidelink relay communication link.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.
