Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communication system support communications between user equipment (UEs). In the examples, a UE may include two or more transmission reception points (TRPs) and may transmit two or more packets on partially or fully overlapping resources via individual TRPs of the two or more TRPs. The UE may identify a first data packet for transmission using a first spatial layer associated with a first TRP and a second data packet for transmission using a second spatial layer associated with a second TRP. The UE may map a portion of the first data packet to a set of resources of the second spatial layer and transmitting a control message indicating that the portion of the first data packet is mapped to the second spatial layer.

Abstract: Disclosed are techniques for non-line-of-sight (NLOS) target detection. In an aspect, a source vehicle receives, from a roadside unit (RSU), a notification that the RSU is capable of repeating radar signals transmitted by the source vehicle in NLOS directions from the source vehicle, receives, from an active radar repeater associated with the RSU, radar signals for a radar beam sweep in at least one NLOS direction from the source vehicle, receives an angle of each beam of the radar beam sweep, and performs target object detection based on the radar signals for the at least one NLOS direction and the angle of each beam of the radar beam sweep. Example architectures for the active radar repeater are also disclosed.

Abstract: The bandwidth of ranging signals used in ranging session in a distributed system are dynamically adjusted based on the accuracy of the ranging over multiple ranging sessions and optionally based on the probability of successful Listen Before Transmit (LBT) procedure over the multiple ranging sessions. The accuracy of the ranging may be determined, e.g., based on the variance of determined ranges over a number of ranging sessions, which may be compared to a threshold to indicate low accuracy ranging. The bandwidth of the ranging signals may be increased based on an indication of low accuracy ranging. If the ranging signals are broadcast on unlicensed spectrum using LBT procedures, the probability of successful LBT procedures by the initiator UE, the responder UEs, or all participating UEs may be used to determine whether bandwidth of the ranging signals should be decreased.

Abstract: Aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a peer-to-peer (P2P) communication is to be relayed based at least in part on a location of the UE and a range requirement associated with the P2P communication; and transmit the P2P communication, wherein the P2P communication includes an indication of whether the P2P communication is to be relayed. In some aspects, a UE may receive the P2P communication; determine whether to relay the P2P communication based at least in part on the indication and at least one of: a location of the UE, or a UE identifier, included in the P2P communication, that identifies the UE and is associated with a request for the UE to relay the P2P communication; and selectively relay the P2P communication based at least in part on determining whether to relay the P2P communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) with multiple transmission reception points (TRPs) (e.g., a multi-TRP UE) may receive sidelink control information including an interference measurement configuration indicating resources allocated for sidelink interference measurements across multiple TRPs. In some cases, the multi-TRP UE may decode the sidelink control information including the interference measurement configuration. The multi-TRP UE may receive one or more signals from a first UE, a second UE, or both. The multi-TRP UE may perform a sidelink interference measurement for each signal based on the interference measurement configuration. The multi-TRP UE may determine whether to process the signals in combination or separately across TRPs based on the sidelink interference measurements.

Abstract: Embodiments include methods performed by a processor of a wireless device for discontinuous reception. The processor may monitor for sidelink control signaling from a base station using a radio of the wireless device during a sidelink control signaling monitoring duration. The processor may receive sidelink control signaling that allocates a sidelink communication resource and schedules a sidelink communication. The processor may perform the scheduled sidelink communication based on the received sidelink control signaling. The processor may place the radio of the wireless device into a low power mode outside of the sidelink control signaling monitoring duration when no sidelink communication is scheduled.
