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: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.

Abstract: Various aspects described herein relate to techniques for connection setup procedures in a wireless communication system (e.g., a vehicle-to-everything (V2X) communication system in millimeter wave). In an aspect, the method includes identifying information for V2X communications, and initiating a random access procedure based on the identified information. The method further includes identifying one or more random access channel (RACH) resources based on the information, identifying one or more RACH response resources based on the one or more RACH resources, and performing directional communications using at least the one or more RACH resources or the one or more RACH response resources.

Abstract: Various features and aspects related to methods and apparatus for interference detection, mitigation and/or avoidance using feedback signaling are described. In accordance with one aspect, a first device may transmit data to a second device in a first transmission slot. The first device may receive feedback from a third device including priority information corresponding to a link between the third device and a fourth device. The first device may determine whether to yield transmission of additional data to the second device during at least a second transmission slot based on the priority information.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating that a base station supports allocating resources for sidelink communications using a first radio access technology (RAT) and a second RAT that is different from the first RAT. The UE may transmit a sidelink information message to the base station using the first RAT that indicates that sidelink communications are to be performed using either the second RAT or both the first RAT and the second RAT. The UE may receive a configuration message from the base station that comprises an identifier for the sidelink communications and an indication of available sidelink resources. The UE may transmit, based at least in part on the configuration message, a request for resources within the available sidelink resources, the request indicating the identifier and a buffer status report (BSR).

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication with a network. In some aspects, the scheduled entity obtains data that is to be transmitted, wherein one or more frequencies are available for transmission of the data. The scheduled entity transmits, to a scheduling entity, a message that includes an amount of the data to be transmitted and a frequency parameter indicating at least one of the one or more frequencies to be used for the transmission of the data. The scheduled entity obtains, from the scheduling entity, a resource grant based on the message and transmits the data based on the resource grant. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication using a set of carrier frequencies. The UE may transmit a request to a base station for resources to use to perform the vehicle-based sidelink communications, the request comprising an indication of the profile, a reliability metric associated with the profile, and an identifier that identifies the set of carrier frequencies. The UE may receive one or more grants from the base station for semi-persistent scheduling resources allocated on the set of carrier frequencies in response to the request.

Abstract: Methods, systems, and devices for wireless communications are described. A method may include identifying, by a first user equipment (UE), a schedule associated with the first UE and a second UE of the group of UEs in direct communications with the first UE. The schedule may include an awake period reserved for directional communications between the first UE and the second UE. The first UE may manage the awake period reserved for the directional communications based on traffic information associated with the first UE, and may communicate with the second UE in accordance with the managing.

Abstract: Aspects of the disclosure relate to methods and apparatus for scheduling traffic between a transmitting device and a receiving device. A transmitting device negotiates with a receiving device to reserve a slot for communicating data with the receiving device and determines whether the transmitting device is a master or a slave with respect to the receiving device. If the transmitting device is the master, the transmitting device sends, at a beginning of the slot, a transmission priority (TxP) signal, wherein the TxP signal indicates that the transmitting device intends and has priority to transmit the data in the slot. The transmitting device then receives, from the receiving device, a clear-to-send (CTS) message in the slot based on the TxP signal, and transmits the data to the receiving device in the slot upon receiving the CTS message. Other aspects, embodiments, and features are also claimed and described.
