Abstract: Methods, systems, and devices for wireless communications are described. In some examples, when a high subcarrier spacing (SCS) is used for sidelink communications, the user equipments (UEs) may use a modified sidelink slot structure for the sidelink communications. In one example, the slot structure may include at least two automatic gain control (AGC) symbols with at least one sidelink control channel symbol between the two AGC symbols. The UE may perform an AGC procedure during the two AGC symbols and the sidelink control channel symbol. In some examples, the slot structure may include bundled slots to minimize per slot overhead associated with AGC symbols and sidelink control channel symbols. For example, at a high SCS, the slot structure may include a first slot including multiple AGC symbols, Subsequent bundled slots may not include AGC symbols and/or sidelink control channel symbols.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes communicating control signaling scheduling a sidelink transmission via a physical sidelink channel, receiving, by a first user equipment (UE), the sidelink transmission including one or more reference signals from a second UE via the physical sidelink channel based on the control signaling, and monitoring the physical sidelink channel based on time synchronization, frequency synchronization, or both, determined using the one or more reference signals.

Abstract: Methods, systems, and devices for wireless communications are described for estimating one or more environmental factors at a first user equipment (UE). The one or more environmental factors may be based on estimates of a Doppler spread and a power delay profile (PDP) taken over a set of subsets of a time period, based on multiple signals received from a second UE or a base station over the time period. The first UE may estimate the Doppler spread and PDP for a channel over each of the set of subsets of the time period, and may combine the Doppler spread over the set of subsets and combine the PDP over the set of subsets. The first UE may use the combined Doppler spread and the combined PDP to determine one or more communication parameters for the channel.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for sharing detection of radio frequency interference among user equipments (UEs). If a first UE detects radio frequency interference affecting a vehicle-to-everything (V2X) link, the first UE may transmit a V2X message to a second UE indicating that the first UE detected the radio frequency interference. The second UE may adjust V2X communications in order to compensate for the radio frequency interference or modify radio frequency interference detection schemes.

Abstract: An apparatus for wireless communication includes a receiver and a transmitter that is configured to transmit a signal during a first slot. The signal has a power level that is associated with a transmission that is to occur during the first slot or during a second slot after the first slot. The signal is distinct from the transmission. The first slot and the second slot occur during a sub-frame time interval associated with a first cellular vehicle-to-everything (CV2X) wireless communication protocol, and the first slot and the second slot are associated with a second CV2X wireless communication protocol different than the first CV2X wireless communication protocol. The transmitter is further configured to perform the transmission during the second slot based on the power level.

Abstract: Methods, systems, and devices for wireless communications are described to support estimation of a transmission quality imbalance between a set of antennas of a first user equipment (UE). The first UE may use the estimated transmission quality imbalance to determine a transmission diversity scheme that may decrease the transmission quality imbalance. The first UE may determine the transmission quality imbalance between the set of antennas by estimating a reception quality imbalance between the set of antennas. The first UE may estimate the reception quality imbalance for multiple subsets of a time period and may combine the reception quality imbalance estimations for the multiple subsets. The combined reception quality imbalance estimations may represent the transmission quality imbalance between the set of antennas, which may be used to determine a transmission diversity scheme for communicating a transmission to a second UE or a base station.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first wireless device. The first wireless device may participate in a beam forming procedure with a second wireless device to evaluate a plurality of transmit (TX) and receive (RX) beam pairs. The first wireless device may select one of the TX and RX beam pairs based on the evaluation. The first wireless device may determine at least one cryptographic key based on channel parameters associated with a selected one of the TX and RX beam pairs. The first wireless device may use the at least one cryptographic key for communications with the second wireless device.
