Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a sidelink communication on a sidelink. The sidelink communication may include at least one of a grant, data received on a resource identified by the grant, a multi-stage grant, a multi-packet grant, or a relaying communication. The wireless communication device may transmit, on the sidelink after a time period since receiving the sidelink communication, a feedback message acknowledging receiving the sidelink communication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

Abstract: Methods, systems, and devices for wireless communications are described. A first relay user equipment (UE) may be configured to receive a first message including a cross-link interference (CLI) indication associated with CLI experienced by a first base station which is associated with signals transmitted by a second base station. The first relay UE may generate, in response to the first message, a second message including the CLI indication, and may transmitting the second message including the CLI indication. In some cases, the first relay UE may transmit the second message directly to the second base station. In additional or alternative cases, the first relay UE may transmit the second message to an additional relay UE for relay to the second base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a first base station or a base station component may receive an assistance information message associated with a sidelink discontinuous reception (DRX) configuration for communications between the first UE and a second UE. The first base station may transmit the assistance information message received from the first UE to a second base station or a second base station component. The first base station and the second base station may communicate with one another via a direct link or an interface, and the second base station may transmit an indication of the sidelink DRX configuration for the first UE to the first base station via the interface. The first base station may then transmit the sidelink DRX configuration to the first UE, along with an access link DRX configuration for the first UE.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support closed-loop transmit power control (TPC) for user equipment (UE) sidelink communications. TPC information may be provided, by a first UE receiving transmissions from a second UE, with respect to a sidelink implemented between the UEs. TPC information may be multiplexed with sidelink data traffic in a sidelink communication between UEs. The TPC information may include a TPC indicator and one or more TPC messages for providing TPC commands with respect to one or more sidelinks. The sidelink data traffic of some examples may include data-only traffic, such as semi-persistent scheduled (SPS) data traffic, that is decoupled from accompanying sidelink control information (SCI). Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first and second user equipment (UE) may perform a handshake procedure to establish a cooperation agreement designating one or more frequency and time resources which the first UE is to act as the proxy device for the second UE. For example, the first UE may receive a sidelink message directed to a second UE from a third UE. The first UE may determine to act as a proxy device for the second UE with respect to the sidelink message based on the sidelink message being received during a time resource designated for the first UE to act as the proxy device for the second UE. The first UE may proceed to transmit to the third UE feedback information associated with the sidelink message, and may transmit the sidelink message to the second UE on behalf of the third UE.

Abstract: Disclosed are techniques for performing positioning operations. In an aspect, a user equipment (UE) receives a downlink physical channel from a base station, the downlink physical channel received via one or more slots of one or more subframes of one or more radio frames, the downlink physical channel carrying user data and/or control information from the base station to the UE, receives, from the base station, an indication that the base station will transmit reference signals for positioning on the downlink physical channel, and performs a positioning measurement of a reference signal received on the downlink physical channel.
