    Abstract: Methods, systems, and devices for wireless communications are described to support transmitting a network coded combined message to a second wireless device that may have missed at least one sidelink message included in another network coded combined message. A first wireless device may identify that the sidelink messages are configured for network coding based on information associated with the sidelink messages. Control information associated with the network coded combined message may indicate that the network coded message is a network coded combined retransmission of the sidelink messages, and may further include information identifying the sidelink messages and devices that transmitted the sidelink messages. The first wireless device may combine the sidelink messages into the network coded combined message and may transmit the control information and the associated network coded combined sidelink message to the second wireless device, which may support decoding of one or more missed sidelink messages.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a sidelink bandwidth part configuration for a plurality of sidelink carriers, wherein the sidelink bandwidth part configuration configures one or more sidelink bandwidth parts for each sidelink carrier of the plurality of sidelink carriers. The UE may identify at least one selected sidelink carrier selected from the plurality of sidelink carriers and an active sidelink bandwidth part for each of the at least one selected sidelink carrier from the one or more sidelink bandwidth parts configured for the at least one selected sidelink carrier. The UE may communicate with another UE in the active sidelink bandwidth part on each of the at least one selected sidelink carrier. Numerous other aspects are described.

    Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for layer 2 relay user equipment (UE) mobility. A relay UE relays data between a first network entity and a remote UE based on a first configuration of the remote UE. The relay UE may receive, from the first network entity on a first connection, a handover request that includes a second configuration for a second network entity or a third configuration for the remote UE. The relay UE determines whether dual active protocol stack radio link control channels are configured for the remote UE based on the first configuration or the third configuration. The relay UE establishes a second connection with the second network entity based on the second configuration, and transmits, to the remote UE, a handover status indicating a result of establishing the second connection with the second network entity.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may establish, via a sidelink signaling interface, a unicast link between the remote UE and a relay UE; establish a connection with a base station via the relay UE, wherein a message associated with establishing the connection is communicated via the unicast link; establish one or more bearers based at least in part on a radio bearer configuration received from the base station via the connection; establish, with the relay UE, one or more sidelink access stratum entities for the one or more bearers using one or more sidelink radio resource control messages based at least in part on an access stratum configuration received from the base station via the connection; and receive or transmit control-plane or user-plane traffic via the one or more bearers.

    Abstract: Aspects of the disclosure relate to sidelink discontinuous reception (DRX) procedures for blind sidelink retransmissions. A first device may obtain a set of sidelink communication parameters that are associated with a second device. Based at least in part on the set of sidelink communication parameters, the first device may transmit to the second device a sidelink blind retransmission configuration. This configuration may include enablement of sidelink blind retransmission and/or establishment of a number of sidelink blind retransmissions. Other aspects, examples, and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine its position by receiving locations from one or more other UEs capable of network-based positioning. For example, a second UE may determine its location using network-based positioning and may transmit its location information to the first UE. The first UE may determine its location based on the received location information (e.g., by calculating a weighted average of different locations, by setting its location to be the same as the received location). In some cases, the first UE may receive location information from other UEs during or after a discovery process with other UEs. In some other cases, the first UE may receive messages (e.g., periodic safety messages) from the other UEs, and the messages may each include location information of the respective other UEs.
