Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first wireless device transmitting, to a third wireless device associated with a signal relaying device, a first message querying whether the third wireless device is able to establish a first communications link with a second wireless device. The first wireless device may receive, from the third wireless device, signaling indicative of whether the third wireless device is able to establish the first communications link with the second wireless device and communicate with the second wireless device via a second communications link using a signal relaying device of the one or more signal relaying devices associated with the third wireless device based on the signaling.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications between a first UE and a second UE. The method includes, at the first UE, receiving, from the second UE, a paging indication message on a sidelink channel, the paging indication message associating the first UE with one or more resources of a common resource pool that includes a plurality of resources for communication on the sidelink channel. The method further includes, based on the received paging indication message, monitoring the one or more resources for a message from the second UE.

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 discontinuous reception (DRX) configuration to be used by the UE for cellular communication with the base station, wherein the DRX configuration indicates a DRX cycle that includes an active time during which the UE is to monitor a physical downlink control channel (PDCCH) and an inactive time during which the UE is to refrain from monitoring the PDCCH; identify a time window for sidelink communication with another UE based at least in part on the DRX configuration; and communicate using one or more sidelink resources in the identified time window. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in a vehicle-to-everything (V2X) system may receive configuration information from an assisting node, such as a roadside unit (RSU), for calculating location information for a target UE in the V2X system. The assisting node may reflect one or more radar signals from the UE towards the target, and from the target back towards the UE according to the configuration information. That is, the assisting node may modify one or more waveform parameters of the reflection according to the configuration information. The UE may calculate location information for the target based on the reflection, such as by classifying the target as non-line-of-sight (NLOS) based on modified waveform parameters, location information of the assisting node, or both.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.
