Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.

Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

Abstract: A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.

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: Features of the present disclosure implementing techniques that allow the user equipment (UE) to autonomously (e.g., without the network control) manage timing synchronization of a plurality of carriers using sidelink synchronization signal (SLSS) from one or more other UEs in order to identify a synchronization source. A synchronization source associated with a frequency carrier from a set of frequency carriers may be selected according to one or more SLSS sync source selection techniques or rules. For instance, the described solution may be utilized to enable UEs to autonomously perform V2X carrier aggregation (CA). In some examples, the synchronization carrier(s) to be searched may be determined based on the SLSS capability of the UE (e.g., transmission and reception of SLSS capabilities of the UE).

Abstract: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.

Abstract: Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.
