Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

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: Various aspects pertain to ways to securing a peer-to-peer communication link that serves to relay transmissions to/from a managed mobile network node. A first user equipment may identify a second user equipment that can communicate via a peer-to-peer wireless interface and serve as a relay between the first user equipment and a managed mobile network node. A relay session key material may be obtained from the managed mobile network node. A peer-to-peer communication link between the first user equipment and the second user equipment may be established or modified by, for example, securing the peer-to-peer communication link based on the relay session key material. A protocol data unit session may be established, over the peer-to-peer communication link, between the first user equipment and the managed mobile network node for secured transmissions there between.

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 IAB 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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for retransmission of sidelink transmissions using network coding. A transmitting device transmits a transport block and a request for a NC encoding device to retransmit the transport block to a plurality of UEs. The NC encoding device transmits a packet encoding a plurality of transport blocks previously transmitted by one or more transmitting devices. The NC encoding device receives a plurality of acknowledgments (ACK) or negative acknowledgments (NACK) for the plurality of transport blocks from the plurality of UEs. The NC encoding device determines whether a respective transport block has satisfied an ACK condition based on the plurality of ACKs or NACKs from the plurality of UEs. The NC encoding device transmits an acknowledgment message to the one or more transmitting devices for at least the respective transport block.

Abstract: Methods, systems, and devices for sidelink wireless communications are described in which a user equipment (UE) engaged in sidelink communications may provide for radio link maintenance of the sidelink connection by initiating a maintenance procedure, such as a measurement procedure, when one or more conditions are detected. The one or more conditions may include a threshold time being exceeded since a data transmission via the sidelink connection, or a threshold time being exceeded since a successful reception of a sidelink transmission from another UE. An access stratum layer at the initiating UE may format a data packet in the absence of higher layer data to be transmitted via the sidelink connection to initiate the maintenance procedure.

Abstract: Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QoS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

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 wireless communications are described that provide for directional quality of service (QoS) targets of a user equipment (UE) for directional communications to multiple UEs in multiple directions. An application layer of the UE may provide data with multiple different directional QoS targets, that may be mapped to multiple QoS data flows that are each configured with different directional QoS targets such as direction and priority associated with the direction. The data may be duplicated for each of the multiple QoS data flows having different QoS parameters, and each QoS data flow may be transmitted in a different direction using a different beam.

Abstract: Methods, systems, and devices for wireless communications are described. Multiple transmitting user equipments (UEs) may send sidelink data transmissions. Receiving sidelink UEs may map sidelink feedback interlaces corresponding to detected sidelink data transmissions to sidelink feedback resources of a common sidelink feedback symbol according to an interlace mapping rule (e.g., defining which contiguous or non-contiguous frequency resources the UE is to use for transmitting sidelink feedback for the received sidelink data messages). The receiving UEs may map one or more replicas of initial interlaces of sidelink feedback resources to additional available resources of the sidelink feedback resources in the common feedback symbol.
