Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit concurrent messages over a sidelink channel to another UE and over an uplink channel to a base station. The UE may transmit, to a base station, a report indicating a capability of the UE to concurrently transmit over a sidelink channel and an uplink channel. The UE may receive, from the base station and based on the report, a transmission configuration scheduling a concurrent sidelink and uplink transmission within a resource shared by the sidelink channel and the uplink channel. The UE may then transmit the concurrent sidelink and uplink transmission within the resource shared by the sidelink channel and the uplink channel based on the transmission configuration. The other UE and the base station may receive the concurrent sidelink and uplink transmission and may decode different layers of the transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating that a base station supports allocating resources for sidelink communications using a first radio access technology (RAT) and a second RAT that is different from the first RAT. The UE may transmit a sidelink information message to the base station using the first RAT that indicates that sidelink communications are to be performed using either the second RAT or both the first RAT and the second RAT. The UE may receive a configuration message from the base station that comprises an identifier for the sidelink communications and an indication of available sidelink resources. The UE may transmit, based at least in part on the configuration message, a request for resources within the available sidelink resources, the request indicating the identifier and a buffer status report (BSR).

Abstract: Aspects are provided of dedicated paging schemes for vehicle UEs to communicate with pedestrian UEs in V2P communication and that also allows pedestrian UEs to power-efficiently monitor for such V2P communications. A vehicle UE provides an indication of a V2P communication to a pedestrian UE in a resource from a plurality of resources. The vehicle UE then transmits a message to the pedestrian UE based on the indication. The pedestrian UE monitors the plurality of resources for the indication of the V2P communication from the vehicle UE. The pedestrian UE receives the indication of the V2P communication. The pedestrian UE then receives the message from the vehicle UE based on the indication.

Abstract: Aspects relate to wireless communication devices configured to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a first sidelink transmission, determine one or more sidelink resources for receiving a second sidelink transmission based at least in part on the resources used to transmit the first sidelink transmission, monitor the determined one or more sidelink resources, and receive via the transceiver the second sidelink transmission on the monitored one or more sidelink resources. According to another example, a wireless communication device can receive a first sidelink transmission, determine one or more sidelink resources for transmitting a second sidelink transmission based at least in part on the received first sidelink transmission, and transmit the second sidelink transmission on the one or more of the determined sidelink resources.

Abstract: Certain aspects of the present disclosure provide techniques for wireless in-vehicle networking. A method that may be performed by a device in a vehicle includes wirelessly transmitting a data packet directly via a first device-to-device (D2D) communication link to another device in the vehicle; monitoring for an acknowledgment (ACK) of the data packet; deciding whether to retransmit the data packet to the other device, based on the monitoring; and wirelessly transmitting the data packet to a transmission relay, wherein an intended destination of the data packet is the other device, wherein the monitoring for the ACK comprises monitoring for a first ACK from the other device and a second ACK from the transmission relay.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with one or more other UEs over a sidelink communications link, and may perform radio link monitoring (RLM) of the sidelink. A first UE may transmit, to a second UE, a first message in a first transmission time interval (TTI) via a sidelink communication link. The first UE may monitor the sidelink communications link during a second TTI subsequent to the first TTI for a feedback message from the second UE in response to the first message transmitted by the first UE. The monitoring may be a part of a RLM procedure for the sidelink communications link. The first UE may increment a counter based on or an unsuccessful receipt of the feedback message in the second TTI.

Abstract: A method of wireless communication wireless communication by an identifier-receiving user equipment (UE) includes measuring a received signal power of multiple resource UEs. The method also includes receiving a set of identifiers from an identifier-transmitting UE. The method further includes identifying a resource used by at least one of the multiple resource UEs for a future transmission from the identifier-receiving UE based on the measured received signal power and the received set of identifiers. The method still further includes scheduling the future transmission on the at least one identified resource.
