Abstract: A method includes cellular vehicle-to-everything (CV2X) allocation collision detection and reporting. An allocation collision detection module detects control channel allocations from transmitting user equipments (UEs) in each time period of a group of time periods. A quantity of detected control channel allocations is determined in each time period. A report is then built and transmitted to at least one of the transmitting UEs. The report indicates collisions in each time period, based on the quantity and a location of the detected control channels in each time period, as well as based on a type of UE interface.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to include procedures to selectively release a portion of hybrid automatic repeat request (HARQ) memory based on the priority of each component carrier of the first connection when performing a radio tune-away to a second connection. For example, the UE may determine the amount of memory space associated with the HARQ processes for the second connection and selectively release a portion of HARQ memory based on the priority of each component carrier of the first connection when the determined amount of memory space is greater than the empty space of the HARQ memory.

Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink (SL) channel selection coordination. A method that may be performed by a user equipment (UE) includes measuring, during a time period shorter than one slot, a channel condition of at least one first channel in a sidelink (SL) frequency band. The method further includes transmitting a signal on the at least one first channel or a second channel of the SL frequency band, wherein the at least one first channel or the second channel is chosen based on the channel condition.

Abstract: A method of wireless communication at a user equipment (UE) includes receiving a first collision report (s), each first collision report indicating at least one first monitored subset of sidelink resources that were monitored by a remote sidelink UE. The method also includes transmitting a second collision report indicating allocation collisions detected by the UE on a second monitored subset(s) of sidelink resources. Each of the second monitored subset(s) of sidelink resources differing from each of the first monitored subset(s) of sidelink resources indicated in the received first collision report(s). The second collision report further comprising an indication of each of the second monitored subset(s) of sidelink resources.

Abstract: Aspects of a methods, apparatus, and computer-readable medium for wireless communication at a wireless device are provided herein. The wireless device may receive a configuration for a resource pool for sidelink communication, the resource pool having a plurality of physical resource blocks (PRBs) including a first set of PRBs that are grouped in one or more sub-channels, each sub-channel having an equal number of PRBs, and a second set of PRBs that are not in the one or more sub-channels having the equal number of PRBs. The apparatus may transmit in the second set of PRBs. The second set of PRBs may not be monitored by a receiving device.

Abstract: Aspects of the disclosure relate to mechanisms for a vehicle-to-everything (V2X) device to prioritize communication from other nearby V2X devices and to selectively process packets from the other nearby V2X devices based on the assigned priorities. The V2X device may measure one or more performance factors of the V2X device, and select one or more other nearby V2X devices to receive and process packets therefrom based on the performance factors and the priorities assigned to the other V2X devices. The V2X device may then ignore any packets received from non-selected V2X devices to reduce and/or control the receive packet flow rate. The performance factors may further be utilized to control one or more transmission characteristics, such as the transmit power and transmit packet flow rate.

Abstract: This disclosure discloses various vehicle-to-everything (V2X) wireless communication processes that use switching diversity to improve coverage over that of a single transmit antenna. Switching diversity may be implemented by alternating the transmit antennas according to a certain switching pattern. A V2X device determines a pattern for alternating a plurality of antennas for transmitting data packets. The V2X device selects, based on the pattern, a first antenna of the plurality of antennas, and transmit a first packet of the data packets using the first antenna. The V2X device further select, based on the pattern, a second antenna of the plurality of antennas, and transmit a second packet of the data packets using the second antenna.
