Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, the present disclosure includes selecting, at a first device, a Random Access Channel (RACH) preamble identifier (ID) from a set of RACH preamble IDs based on a discovery procedure associated with a second device, wherein each RACH preamble ID from the set of RACH preamble IDs corresponds to at least one RACH preamble and is associated with the second device; and transmitting, from the first device, a RACH preamble associated with the selected RACH preamble ID to the second device.

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: Techniques are provided for supporting sidelink communication between multiple user equipment (UEs), and which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects a first UE may establish a sidelink schedule with a second UE, wherein the sidelink schedule corresponds to at least a subset of communication resources indicated available to both the first and second UEs by one or more corresponding link availability schedules or the like. The two UEs may then establish a sidelink with the second UE in accordance with the sidelink schedule. Multiple sidelink schedules may be agreed upon in certain instances such that the UEs may dynamically switch from one schedule to another as desired.

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, systems, and devices for wireless communication are described that provide for priority-based carrier selection in a system using multiple component carriers (CCs). A mapping may be provided that maps different applications that may be present at a user equipment (UE) to one or more CCs. Each application may have an associated application priority, and each carrier associated with an application may also have an associated CC priority. A UE may select a subset of CCs for a transmission based on the mapping between an application providing a packet for the transmission and the priority associated with each CC. A UE, when receiving transmissions, may identify one or more applications running at the UE and use the mapping to determine a subset of CCs to monitor for transmissions.

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 communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.
