Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify a first channel group comprising a first radio bearer and a second channel group comprising a set of second radio bearers. In some examples, the first channel group further comprising a one-to-one mapping between the first radio bearer and a first channel of a backhaul network and the second channel group comprising a many-to-one mapping between the set of second radio bearers and a second channel of the backhaul network. The transmitting device may transmit a first packet on the first channel of the first channel group of the backhaul network, the first packet comprising a mapping indicator set to a first value and a first identifier associated with the first channel of the first channel group.

Abstract: Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a vehicle UE. For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted.

Abstract: Certain aspects of the present disclosure provide techniques for assigning or adjusting a transmit-power control mode, or parameters of a transmit-power at a user equipment used in sidelink communications. In some examples, the disclosure describes determining a user equipment (UE) is connected to the BS, and configuring the UE to use a first transmit-power control mode for determining a transmit-power used for transmitting wireless data over a sidelink based on the BS being positioned indoors.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) can transmit a device-to-device (D2D) communication. The D2D communication can include an application layer message and the application layer message includes one or more data elements related to a geo-fence for the UE.

Abstract: The present disclosure relates to methods and devices for group communication which may include a first UE and a set of UEs. In one aspect, the first UE may receive from each UE of the set of UEs a PDU including a header that includes a QoS level for the UE. The first UE can also determine a supported QoS level for the first UE. In another aspect, the first UE can set a transmission QoS level for the first UE to be a lowest QoS level of the determined supported QoS level and the QoS level from each UE of the set of UEs. In a further aspect, the first UE can transmit by multicast to the set of UEs a PDU based on the set transmission QoS level.

Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for access and backhaul links 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 given link type (e.g., access or backhaul). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given link type. The allocated resources may be repurposed for use by a different link type (e.g., access resources may be repurposed and used for backhaul resources) in order to account for varying traffic conditions.

Abstract: Aspects described herein relate to prioritizing certain types of uplink communications, which can include identifying a first priority level associated with sidelink traffic, identifying a second priority level associated with uplink traffic, determining, based at least in part on comparing the first priority level with the second priority level, whether to prioritize the sidelink traffic or the uplink traffic, and transmitting, based at least in part on determining whether to prioritize the sidelink traffic or the uplink traffic, at least one of the sidelink traffic or the uplink traffic.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may transmit a sidelink request to reserve a subset of data resources to a second UE, and may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The second UE may transmit a positive sidelink response if it is available for a data transmission. A third UE may transmit a negative sidelink response if it objects to the data transmission. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.
