Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may determine a plurality of antenna configurations for a plurality of channel frequencies. The UE may determine a set of signal strengths for at least one beam received at one or more antenna configurations of the plurality of antenna configurations for at least one of the channel frequencies. The UE may select, based on the set of signal strengths, a first antenna configuration of the plurality of antenna configurations. After selection of the first antenna configuration, the UE may communicate with a base station, in one or more channel frequencies based on the first antenna configuration.

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.

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: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a limit on a number of resource blocks (RBs) permitted to be used for a vehicle-to-everything (V2X) transmission by the UE; may determine, based at least in part on the limit, one or more parameters for the V2X transmission, wherein the one or more parameters include at least one of a modulation and coding scheme (MCS) for the V2X transmission, a number of transport blocks (TBs) for the V2X transmission, a number of RBs per TB for the V2X transmission, or a retransmission configuration for the V2X transmission; and may transmit the V2X transmission based at least in part on the one or more parameters. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure implement techniques that allow a vehicle performing V2X communications to provide more accurate S-RSSI measurements and CBR calculations for use in channel selection and congestion control. Techniques may include measuring a sidelink received signal strength indicator (S-RSSI) for each of a plurality of sub-channels, determining one or more signal impairment adjustment factors based on the S-RSSI for each of the plurality of sub-channels, calculating a channel busy ratio (CBR) for the plurality of sub-channels based on the one or more signal impairment adjustment factors, and initiating communication with at least one of the plurality of sub-channels based on at least the CBR.

Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

Abstract: Cell reselection for transitioning a user device from a macro cell to a small cell may be performed by comparing a first reselection candidate small cell and a second reselection candidate small cell based on reselection criteria, and selecting a final reselection candidate based on the comparison.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive sidelink control information (SCI) associated with a remote vehicle; identify a threat metric associated with the remote vehicle based at least in part on one or more characteristics of the remote vehicle, wherein the one or more characteristics are determined based at least in part on vehicle information received in one or more transport blocks corresponding to prior SCI associated with the remote vehicle and received prior to the SCI; and process the SCI based at least in part on the threat metric. Numerous other aspects are provided.
