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 disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: Methods and apparatuses for wireless communication are provided. The apparatus may be a user equipment (UE) integrated within a vehicle. In some aspects, the UE may receive sidelink control information (SCI) including at least one scheduling assignment and priority information. The UE may further select a transmission resource for transmission of data from a set of transmission resources based on one or both of the at least one scheduling assignment or the priority information. Additionally, the UE may transmit the data on the selected transmission resource. In some aspects, a UE may determine whether a priority level of data satisfies a priority level threshold. The UE may further transmit the data on the first transmission resource via a device-to-device (D2D) interface. Moreover, the UE may transmitting the data on at least one of the first transmission resource or a second transmission resource via a network entity interface.

Abstract: Various aspects of the disclosure relate to facilitating multiple hybrid automatic repeat request (HARQ) transmissions. For example, the teachings herein may be used for multiple HARQ transmissions in vehicle-to anything (V2X) communication or some other type of communication. The disclosure relates in some aspects to sending information indicative of the number of scheduling assignment (SA) symbols being sent by a device in conjunction with HARQ transmissions. The disclosure relates in some aspects to reserving resources for multiple HARQ transmissions and communicating an indication of the reserved HARQ resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment may determine a beam to be used to transmit a vehicle-to-everything (V2X) communication to a receiver UE; may determine one or more eligible resource blocks of the beam that are candidates for the V2X communication based at least in part on a schedule associated with the beam; may transmit, to the receiver UE, a proposed schedule that indicates the one or more eligible resource blocks of the beam that are candidates for the V2X communication; and may transmit the V2X communication to the receiver UE via the beam based at least in part on transmitting the proposed schedule. Numerous other aspects are provided.

Abstract: When a UE in a first cell operating at a first frequency attempts to discover another UE in a second cell operating at a second frequency, the UE in the first cell may need to constantly monitor communication on the second frequency to discover the UE in the second cell, which may not be desirable. According to an aspect of the disclosure, the apparatus receives, on a first frequency of a first channel from a first base station serving a first cell, discovery information associated with a second frequency of a second channel corresponding to a second cell, wherein the first frequency is a downlink (DL) frequency and the second frequency is an uplink (UL) frequency. The apparatus discovers, based on the received discovery information, one or more UEs on the second frequency of the second channel.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.
