Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., a relay UE) may establish a relay connection for routing communications between a network entity (e.g., a base station) and a second UE (e.g., a remote UE). The relay connection may include a sidelink connection and an access link connection. The remote UE may transmit a request to the network entity via the relay UE. The request may include a relay service code associated with the sidelink connection, as well as a request for quality of service (QoS) support for the relay connection. Based on the request, the network entity may determine a QoS configuration for the relay connection. The network entity may indicate the QoS configuration to the UEs via the relay connection. The UEs may adjust parameters of the relay connection to meet the specifications of the QoS configuration.

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: Methods, systems, and devices for wireless communications are described. The described techniques provide for the configuration and operation of a multi-hop relay at different layers to enable a remote user equipment (UE) to act as a relay for a client UE that may be out of coverage of a network. For example, a network relay UE may establish a communication link with the network, and the network relay UE may transmit, to a remote UE, a relay configuration that authorizes the remote UE as a multi-hop relay to provide a connection to the network for one or more other UEs. The remote UE may transmit an acknowledgement to the network relay UE in response to receiving the relay configuration, and the remote UE may then transmit a relay discovery message including multi-hop relay information based on receiving the relay configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a sidelink connection with a second UE, where the sidelink connection is associated with a plurality of flows. The first UE may determine, based on monitoring each flow of the plurality of flows, a radio link status of the sidelink connection. The first UE may transmit, based on the determining, a non-access stratum layer message to the second UE based at least on the radio link status of the sidelink connection.

Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an TAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

Abstract: Techniques described herein provide for enhanced determination of a V2X communication range based on sensor information obtained at a V2X device. According to embodiments, a V2X device can obtain sensor information regarding a detected object and determine a communication range for a V2X message transmitted by the V2X device based on one or more detected properties of the detected object. The V2X message itself may contain information regarding the one or more detected properties of the detected object, as well as information indicative of the location of the V2X device and the determined communication range.

Abstract: Methods, systems, and devices for sidelink groupcast communications are described. A user equipment (UE) may transmit a beam training request to a base station to determine beams for use with other UEs in a sidelink groupcast communications group. The base station may receive the beam training request, identify wireless resources that a group of UEs may use to perform beam training, and may transmit a beam training grant to each UE of the group of UEs. The UE may transmit a number of training beams using the wireless resources provided in the beam training grant, and the other UEs may measure received signals on the wireless resources to identify one or more beams. Each UE may provide a beam training report to the base station. The base station, based on the beam training reports, may determine beams and resources for use in the groupcast sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A receiver user equipment (UE) may communicate with a transmitter UE in a sidelink channel to report a congestion index to the transmitter UE and/or additional transmitter UEs, where the transmitter UE(s) may then adjust one or more sidelink operation parameters based on the reported congestion index. In some cases, the transmitter UE may report the congestion index to an upper layer, to other transmitter UEs, to application layers, or a combination thereof. The transmitter UEs 115 and/or application layer may then adjust one or more sidelink transmission operation parameters based on the reported congestion index. For example, the transmitter UEs and/or application layer may adjust threshold values to lessen a number of retransmissions and lessen congestion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication using a set of carrier frequencies. The UE may transmit a request to a base station for resources to use to perform the vehicle-based sidelink communications, the request comprising an indication of the profile, a reliability metric associated with the profile, and an identifier that identifies the set of carrier frequencies. The UE may receive one or more grants from the base station for semi-persistent scheduling resources allocated on the set of carrier frequencies in response to the request.

Abstract: Methods, systems, and devices for wireless communications are described. A method may include identifying, by a first user equipment (UE), a schedule associated with the first UE and a second UE of the group of UEs in direct communications with the first UE. The schedule may include an awake period reserved for directional communications between the first UE and the second UE. The first UE may manage the awake period reserved for the directional communications based on traffic information associated with the first UE, and may communicate with the second UE in accordance with the managing. The awake period reserved for directional communications may include an awake period reserved for uni-directional communications or an awake period reserved for bi-directional communications.
