Abstract: Aspects of the disclosure relate to mechanisms for code block segmentation in a wireless communication network (e.g., a sidelink network). In some examples, a wireless communication device may reserve resources across two or more slots on a carrier for transmission of a transport block. The wireless communication device may then select code block parameters for segmenting the transport block into a plurality of encoded code blocks such that each encoded code bock is fully contained within a single slot. In some examples, the code block parameters may include a number of encoded code blocks and a respective size of each of the encoded code blocks.

Abstract: In an aspect, a vehicle apparatus of a vehicle obtains, based on sensor data from one or more vehicle sensors communicatively coupled to the vehicle, intra-lane position data relative to the vehicle, the intra-lane position data indicating at least one lateral distance between at least one side of a primary vehicle and at least one lane reference point. The vehicle apparatus transmits the intra-lane position data to one or more neighboring entities. In another aspect, a vehicle management device obtains intra-lane position data that indicates at least one lateral distance between at least one side of at least one observed vehicle of a plurality of neighboring vehicles and at least one lane reference point, and instructs at least one vehicle of the plurality of neighboring vehicles to perform one or more actions based on the intra-lane position data.

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: 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: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to methods for wireless communication. A transmitting device transmits a first portion of a control message to a receiving device. The first portion includes information for decoding a second portion of the control message and for decoding data. The transmitting device then transmits the second portion to the receiving device, the second portion including additional information for decoding the data. Thereafter, the first device transmits the data to the receiving device. The receiving device receives the first portion and the second portion, and decodes the received second portion based on the information included in the first portion. The receiving device then receives the data from the second device if the received second portion is able to be decoded. The receiving device decodes the received data based on the information included in the first portion and the additional information included in the second portion.

Abstract: Methods, systems, and devices for wireless communications are described. A device, which may be otherwise known as user equipment (UE) may support sidelink communications, for example, such as device-to-device (D2D) communications, vehicle-based communications, which may also be referred to as vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, and the like. To mitigate or decrease collisions or other interference on resources (e.g., time and frequency resources) used by other UEs in sidelink communications, a UE may determine a blind retransmission of a packet, determine that the packet satisfies one or more conditions based in part on the blind retransmission, and transmit feedback signal relating to the blind retransmission of the packet.

Abstract: Certain aspects of the present disclosure provide techniques for half-duplex handling with system-wide feedback resources. Embodiments include determining, for a first feedback resource corresponding to a first time period, that the wireless node has a scheduled feedback transmission and a scheduled feedback reception on shared frequency resources. Embodiments include selecting one of the scheduled feedback transmission or the scheduled feedback reception based on a rule. Embodiments include using the feedback resource to perform the selected one of the scheduled feedback transmission or the scheduled feedback reception.
