Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) carried by a pedestrian (e.g., a P-UE) may receive control signaling that indicates a resource allocation for a sidelink channel for pedestrian to vehicle communications. The P-UE may transmit, within the resource allocation of the sidelink channel, a message that includes an identifier of the P-UE based on movement data of the P-UE being classified as pedestrian movement. The P-UE may monitor the sidelink channel for a collision warning message from a vehicle UE that includes the identifier of the P-UE based on transmitting the message. If the P-UE receives a collision warning message that includes its identifier, the P-UE may present an alert based on receiving the collision warning message.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for transmitting ranging signals in a vehicle-based communication system. The configuration may identify a plurality of channels to be used for the ranging signals and timing for the ranging signals. The wireless device may transmit the configuration to a receiver and transmit ranging signals based at least in part on the configuration. The receiver may use the ranging signals to determine a distance between the receiver and the wireless device. The receiver may use the determined distance to update positioning information or operate a motor vehicle.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a selection window after an arrival of a packet. The selection window may be selected based at least in part on a delay budget associated with the packet. The UE may determine, based at least in part on the selection window, a control exclusion zone value. The UE may perform, based at least in part on the control exclusion zone value, a resource selection associated with determining available resources for transmitting a set of transmissions associated with the packet. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a plurality of ratios of free resources in a historical time window using respective control exclusion parameters corresponding to the plurality of ratios of free resources. The UE may determine a particular control exclusion parameter based at least in part on a ratio of free resources, of the plurality of ratios of free resources, satisfying a threshold. The UE may select a resource for a future transmission based at least in part on the particular control exclusion parameter. The UE may reserve the selected resource. Numerous other aspects are provided.

Abstract: In a device to device (D2D) communication scenario such as vehicle to anything (V2X) communications, channel access of a device such as a user equipment (UE) may not be controlled by network devices. Using the disclosed channel access mechanism, a device may autonomously access a channel for transportation related communications. A device may determine to transmit a data packet in a portion of bandwidth. The device may select a listen before talk counter defining a time period to wait before beginning a transmission of the data packet. The device may sense the portion of bandwidth during the time period for transmissions of other UEs occupying frequency resource blocks within the portion of bandwidth. The device may select unoccupied frequency resource blocks within the portion of bandwidth based on the sensing. The device may transmit the data packet on the unoccupied frequency resource blocks after the period of time.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a peer device. The method generates control information to schedule peer-to-peer communication. The control information includes a first portion with a first set of data and a second portion with a second set of data. The method then transmits the first portion of the control information in a first stage using first time and frequency resources. The first portion indicates a control information format of the second portion. The method further transmits the second portion of the control information in a second stage using second time and frequency resources and the indicated control information format.

Abstract: The present disclosure relates to methods and devices for communication which may include a transmitting device and at least one receiving device. In one aspect, the transmitting device may determine a transmission configuration including one or more aggregated transmission intervals for communicating with the receiving device. The transmitting device may also indicate the transmission configuration to the receiving device. Additionally, the transmitting device can transmit at least one data packet to the receiving device based on the transmission configuration. Further, the transmission configuration can indicate a number of the one or more aggregated transmission intervals. In some aspects, the receiving device can determine a number of aggregated transmission intervals based on the indication. The receiving device can also decode the data packet based on the number of aggregated transmission intervals.

Abstract: Techniques are described for wireless communication at a wireless device. One method includes transmitting, during a TTI, a first message using a first MCS; and transmitting, during the TTI, a second message using a second MCS. The first message includes indications of a location, a heading, and a speed of the wireless device, and the second MCS is higher than the first MCS. Another method includes decoding a first message received during a TTI; performing a Doppler effect compensation for a second message based at least in part on the first message; and decoding the second message based at least in part on the Doppler effect compensation. The second message is also received during the TTI. The first message is decoded in accordance with a first MCS, and the second message is decoded in accordance with a second MCS, with the second MCS being higher than the first MCS.
