Abstract: Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) establishes a radio resource control (RRC) connection for a communication session with a second UE, establishes a signaling radio bearer (SRB) for the communication session with the second UE on a first frequency band, sends, to the second UE over the SRB on the first frequency band, a first RRC message to establish a data radio bearer (DRB) for the communication session on a second frequency band, the first RRC message including one or more parameters for establishing the DRB on the second frequency band, and configures the DRB on the second frequency band based on the one or more parameters in the first RRC message and/or a device-to-device discovery procedure performed in the first frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), such as a pedestrian UE, may perform a discovery procedure with a second UE in a vehicle-to-everything (V2X) wireless communications environment that includes multiple other UEs in addition to the first UE and the second UE. The second UE may, for example, be a roadside UE configured to aggregate V2X messages for the first UE. The first UE may determine, based on performing the discovery procedure, a schedule for the first UE to use to receive bundled V2X messages from the second UE. The first UE may receive, from the second UE based on the determined schedule, a message indicating bundled information from multiple V2X messages received at the second UE from the multiple UEs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

Abstract: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

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.
