Abstract: Wireless communication systems and methods related to quality of service mapping, are provided. A first user equipment determines a sidelink radio bearer identifier (SLRB ID) for a quality of service (QoS) flow from a plurality of rules. The rules identify different characteristics of the QoS flow. The SLRB ID is inserted into a header of a packet in the QoS flow. The QoS flow is mapped to a radio bearer that is mapped to an L2 link with other radio bearers that are mapped to other QoS flows. The L2 link transmits the radio bearers to a second UE as part of a broadcast, groupcast or unicast sidelink communication. Based on the SLRB ID, the second UE identifies requirements of the QoS flow.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE), a system information block of type 21 (SIB21) from a network device. The SIB21 indicates a communication resource pool associated with a sidelink. The method further includes receiving one or more messages from the network device based on receiving the SIB21 and prior to communicating using the communication resource pool. The method further includes communicating, based on verifying an identity of the network device based on the one or more messages, via the sidelink using the communication resource pool and based on a vehicle-to-everything (V2X) wireless communication protocol.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.

Abstract: Techniques are provided for supporting sidelink communication between multiple user equipment (UEs), and which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects a first UE may establish a sidelink schedule with a second UE, wherein the sidelink schedule corresponds to at least a subset of communication resources indicated available to both the first and second UEs by one or more corresponding link availability schedules or the like. The two UEs may then establish a sidelink with the second UE in accordance with the sidelink schedule. Multiple sidelink schedules may be agreed upon in certain instances such that the UEs may dynamically switch from one schedule to another as desired.

Abstract: A transmitting device may determine a zone identifier (ID) for the transmitting device and transmit a message including the zone ID directly to at least one receiving device. In certain aspects, a relay device may be configured to receive the message comprising a first zone ID for a transmitting device, to determine whether to relay the message based at least on the first zone ID, and if the relay device determines to relay the message, to transmit a relayed message including information reflecting the first zone ID. In certain aspects, a receiving device may be configured to identify a message comprising information indicating a first zone ID for a transmitting device, to determine whether to decode data of the message based at least on the first zone ID for the transmitting device, and to decode or refrain from decoding the data of the message based on the determination.

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: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for types of traffic separately. A centralized scheduler in a centralized system or a set of access nodes (ANs) in a distributed system may allocate a portion of a set of resources for a first traffic type (e.g., control or data traffic). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given traffic type. The allocated resources may be repurposed for use by a different traffic type (e.g., data traffic resources may be repurposed an used for control traffic resources) in order to account for varying traffic conditions (e.g., unscheduled control traffic).

Abstract: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may transmit a sidelink request to a second UE. The sidelink request may indicate a set or a segment of the data resources. A second UE may transmit a positive sidelink response indicating that the set or the segment of resources is available for reservation, or may refrain from transmitting a positive sidelink response if the set or the segment of the data resources is unavailable for reservation. A third UE may transmit a negative sidelink response indicating that the set or the segment of the data resources is unavailable for reservation, or may refrain from transmitting a negative sidelink response if the set or the segment of the data resources is available for reservation. If the requested data resources are available, then the first UE may transmit a sidelink confirmation reserving the requested data resources.
