Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more measurements associated with a sidelink resource pool that includes one or more time and frequency resources allocated to sidelink transmissions to or from the UE. The UE may transmit, to an assisted UE, sidelink signaling that includes signaling to wake up the assisted UE and resource assistance information indicating the one or more measurements associated with the sidelink resource pool. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) establishes a radio resource control (RRC) connection for a communication session with a second UE, establishes a signaling radio bearer (SRB) for the communication session with the second UE on a first frequency band, sends, to the second UE over the SRB on the first frequency band, a first RRC message to establish a data radio bearer (DRB) for the communication session on a second frequency band, the first RRC message including one or more parameters for establishing the DRB on the second frequency band, and configures the DRB on the second frequency band based on the one or more parameters in the first RRC message and/or a device-to-device discovery procedure performed in the first frequency band.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

Abstract: A method, a computer-readable medium, and an apparatus for wireless communication at a first user equipment (UE). A channel state information (CSI) report trigger can be received from a second UE, and a channel state information reference signal (CSI-RS) can be received from the second UE in a same slot as the CSI report trigger. A CSI report can be transmitted to the second UE based on the CSI-RS, the CSI report including information identifying the CSI-RS on which the CSI report is based. The UE that triggered the CSI report can determine the CSI-RS on which the CSI report is based using the information included in the CSI report.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate a radio resource control (RRC) layer signaling procedure between the UE and a target UE, include an upper layer signaling message in an RRC message based in part on the RRC layer signaling procedure, and transmit the RRC message including the upper layer signaling message to the target UE. Alternatively, upper layer signaling messages may be transmitted separately before or after the RRC layer signaling procedure.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

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.
