Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may generate a pseudorandom noise (PN) sequence, modulate the PN sequence based at least in part on a modulation order parameter, and transmit the PN sequence in one or more symbols prior to transmitting sidelink data. The one or more symbols used to transmit the PN sequence may be used for automatic gain control (AGC) training at a receiving device. The user equipment may then transmit the sidelink data in a plurality of symbols that are subsequent in time relative to the one or more symbols used to transmit the PN sequence, and the receiving device may process the sidelink data based on the AGC training. Numerous other aspects are provided.

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: 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: Aspects of the disclosure relate to mechanisms for a user equipment for indicating resources having limited wireless wide area network (WWAN) transmission capability. In some examples, a user equipment indicates a sidelink transmission pattern to a WWAN, receives one or more uplink transmission grants for the WWAN based on at least the sidelink transmission pattern, and transmits at least one of first data to a second user equipment on a sidelink channel based on the sidelink transmission pattern or second data to the WWAN based on the one or more uplink transmission grants. In some examples, the user equipment transmits a sidelink transmission configuration to the WWAN, the sidelink transmission configuration including one or more sidelink transmission patterns. In some examples, the user equipment selects a sidelink transmission pattern from among the one or more sidelink transmission patterns based on expected sidelink transmissions.

Abstract: Various aspects described herein relate to techniques for resource configuration for random access in a wireless communication system (e.g., a cellular vehicle-to-everything (CV2X) communication system). In an aspect, the method includes identifying a set of one or more random access channel (RACH) resources and configuration, sending a first RACH message including the set, and receiving a second RACH message including a resource selected from the set.

Abstract: Certain aspects of the present disclosure provide techniques for assigning or adjusting a transmit-power control mode, or parameters of a transmit-power at a user equipment used in sidelink communications. In some examples, the disclosure describes determining a user equipment (UE) is connected to the BS, and configuring the UE to use a first transmit-power control mode for determining a transmit-power used for transmitting wireless data over a sidelink based on the BS being positioned indoors.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating a wakeup opportunity associated with receiving one or more messages from an application and may identify a mapping between an attribute of the signal and an identifier associated with the application. The UE may determine a wakeup procedure in response to receiving the signal based on the mapping between the attribute of the signal and the identifier associated with the application.
