Abstract: Various aspects of the present disclosure generally relate to wireless communication. A source user equipment (UE) may transmit, to a relay UE, information identifying that the relay UE is one of a plurality of relay UEs selected for cooperative relaying of a communication from the source UE to a destination UE. A channel between the source UE and the relay UE may be one of a plurality of channels comprising a channel between the source UE and each relay UE of the plurality of relay UEs. The plurality of relay UEs may be selected based at least in part on a degree of correlation of the channel between the source UE and the relay UE with at least one other channel of the plurality of channels. The UE may transmit the communication to the plurality of relay UEs for cooperative relaying to the destination UE. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a super slot configuration for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method of wireless communication by a user equipment (UE) includes obtaining a sidelink resource pool configuration including configuration of one or more super slots, wherein each super slot includes a plurality of slots contiguous in a time domain The UE may select one or more sidelink resource slots for sidelink transmissions in a sidelink resource pool and transmit an enhanced sidelink control information (eSCI) message in a first slot of a first super slot, wherein the eSCI message indicates a reservation of slots corresponding to the one or more sidelink resource slots. The UE may then send the sidelink transmissions on at least one slot of the reserved slots. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a secondary user equipment (UE), a first grant to conditionally transmit one or more data messages over a first set of resources upon completion of a detection procedure. The detection procedure may include monitoring a second set of resources for over-the-air (OTA) signals transmitted by a primary UE pursuant to a second grant, where the first set of resources at least partially overlaps the second set of resources. The UE may monitor for the OTA signals from the primary UE, determine that one or more conditions for transmission of the one or more data messages have been satisfied, and transmit the one or more data messages over the first set of resources.

Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first downlink control information (DCI) message indicating a first listen-before-talk (LBT) grant for accessing a sidelink channel, the first DCI being associated with a first search space of the UE. The UE may then receive a second DCI message indicating a second LBT grant for accessing the channel or an uplink channel, the second DCI being associated with a second search space of the UE and including an activation trigger for the first LBT grant of the first DCI. The UE may then perform a first LBT procedure to access the sidelink channel in accordance with the first LBT grant during a first channel occupancy time (COT). The UE may further perform a second LBT procedure to access the uplink channel during the first COT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.
