Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.

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.

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: 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: Certain aspects of the present disclosure provide techniques for adaptive antenna mode switching. An example method performed by a wireless device includes reporting first capability information indicating that the wireless device supports a first antenna mode associated with a first number of receive antennas, detecting radio conditions that favor a second antenna mode associated with a second number of receive antennas, and performing one or more actions to cause a switch to the second antenna mode based on the detected radio conditions.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to mechanisms for enhancing pedestrian to vehicle (P2V) communications. For example, a pedestrian user equipment (P-UE) may detect a change in at least one of: location or motion of the UE adjust, based on the detection, behavior of one or more features of the UE related to P2V transmissions.

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.
