Abstract: Techniques for handling sidelink feedback signaling in situations where collisions would otherwise be experienced in a network communication link are shown and described. For example, sidelink feedback signaling handling techniques may provide for collision handling when sidelink HARQ is to be simultaneously transmitted with network communication radio interface uplink channel information (e.g., Uu HARQ, SR, CSI, etc.) on one or more Uu channel (e.g., PUSCH, PUSCH, etc.). In operation of sidelink feedback handling, a transmitter or intermediary UE of a sidelink communication link may decide whether and how to forward the sidelink HARQ to a corresponding base station. Other aspects and features are also claimed and described.

Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

Abstract: Certain aspects of the present disclosure provide techniques for distance-based HARQ feedback transmission. A method that may be performed by a user equipment (UE) includes monitoring for a data transmission from another UE, receiving an indication of a first zone identifier (ID), determining a nearest zone to the UE of multiple zones, wherein the multiple zones are determined based at least in part on the indication of the first zone ID, determining a distance between the UE and the other UE based on the first zone ID, wherein the determined distance comprises a distance between the UE and the nearest zone, and transmitting hybrid automatic repeat request (HARQ) feedback for the data transmission based at least on the distance.

Abstract: A method, a computer-readable medium, and an apparatus for V2V, V2X, or D2D communication may be a transmitting device configured to determine a source ID for communication over a link, to determine a destination ID for the communication over the link based on a type of the communication. The transmitting device may be further configured to transmit at least one control message over the link, where the control message(s) indicate the source ID and the destination ID. In certain aspects, a receiving device may be configured to receive the control message over the link, where the control message indicates the source ID and the destination ID. The receiving device may be configured to receive a data message over the link and to determine whether to attempt to decode the data message received over the link based on the source ID and the destination ID indicated in the control message.

Abstract: A device receives a coded message from a re-transmitting device designated by one or more devices for performing message re-transmission on their behalf. The coded message encodes a first message and a second message, where the receiving device has failed to receive at least the second message. The receiving device further receives a coding-based re-transmission indicator indicating that the coded message is configured as a coding-based re-transmission of two or more previously transmitted messages that are encoded together in the coded message. The receiving device recovers the second message by decoding the coded message. In another aspect, a re-transmitting device is designated by one or more devices for performing message re-transmission on behalf of the devices. The device generates a coded message that encodes a first and a second message; and transmits the coded message and an indicator indicating that the coded message is a coding-based re-transmission.

Abstract: A user equipment (UE) in a vehicle (V-UE) broadcasts multi-phased ranging signals with which other entities may determine the range to the V-UE. The multi-phased ranging signals may include a first message, which may be broadcast in the Intelligent Transport System (ITS) spectrum, includes ranging information, such as a source identifier, location information for the broadcasting V-UE, and an expected time of broadcast of the ranging signal. The ranging signal may then be broadcast at the expected time and may include the source identifier. A second message, which be broadcast in the ITS spectrum, may include clock error information for the V-UE. A receiving entity may determine the range to the V-UE based on the time of arrival of the ranging signal and the expected time of transmission, as well as the clock error information. The receiving entity may further generate a position estimate based on the received location information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may receive, for communication in a network, information identifying a channel access frame structure, wherein the channel access frame structure is associated with a plurality of transmission time intervals (TTIs) grouped into a single frame, and wherein resources of the plurality of TTIs are allocated for transmission of reservation signal based at least in part on prioritization information. The transmitter device may transmit, to a receiver device, a reservation signal using a resource of the plurality of TTIs to indicate use of a subsequent resource for a subsequent transmission based at least in part on the channel access frame structure and a prioritization of the subsequent transmission. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to mechanisms to provide physical sidelink feedback channel (PSFCH) negotiation during sidelink connection establishment. A first UE may determine one or more conditions for PSFCH communications via the sidelink session(s) with the second UE. If the second UE accepts the conditions provided, the first and second UEs complete the sidelink connection. Further, while the first UE has a sidelink communication session with the second UE, a third UE may initiate another sidelink connection with the first UE. The first UE may compare the priority of the proposed sidelink connection with the priority of the ongoing sidelink communication session with the second UE. If the second UE's priority is greater, the first UE will maintain the second UE's status. If less, the first UE may engage in a renegotiation with second UE for the ongoing sidelink communication session to update their PSFCH conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A device may determine a packet for transmission and determine whether to transmit a reservation signal prior to the transmission of the packet based in part on a condition. The condition may include, but is not limited to, a packet size, or a packet priority, or a combination thereof. According to the determination, the device may refrain from transmitting the reservation signal or allocate resources for the reservation signal from a same resource pool associated with the transmission of the packet or a dedicated resource pool according to a pre-reservation resource pattern.
