Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a size of sets of consecutive subcarriers on which channel-based tone reservation is to be applied for one or more communications. The UE may communicate the one or more communications having tone reservation applied to one or more sets of consecutive subcarriers. Numerous other aspects are described.

Abstract: A method detecting allocation collisions from transmitting user equipments (UEs) in sidelink channel resources. The colliding allocations are detected and the quantity of allocation collisions is determined. A collision report is transmitted to other sidelink UEs within the coverage zone. The collision report or collision notification provides an indication of sidelink resources having identified colliding allocations. The identified allocation collisions may be pruned to remove potentially intentional collisions before collision report transmission.

Abstract: Aspects relate to reconstructing a received non-linearly distorted (e.g., clipped) signal. A transmitting device may non-linearly distort a signal to be transmitted (e.g., by clipping peaks of the signal). This non-linear distortion may adversely affect decoding of the signal at a receiving device. To improve decoding performance at the receiving device, the transmitting device provides information regarding some of the non-linear distortion (e.g., information regarding a subset of the peaks that have been clipped) to the receiving device. The receiving device may reconstruct the signal based on this information (e.g., by reconstructing the subset of the peaks and adding the reconstructed peaks to the received clipped signal). In addition, the receiving device estimates the remaining non-linear distortion in the reconstructed signal (e.g., due to clipped peaks that were not indicated in the clipping information) by slicing the reconstructed signal and clipping the sliced signal, and provides a final reconstructed signal.

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.

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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for data aided phase tracking reference signals (PT-RSs); and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: Aspects are provided which allow a UE to apply a modified interference cleaning data to account for differences in interference between at least one pilot resource and at least one data resource, thereby improving data decoding performance of the UE. The UE receives at least one pilot resource and at least one data resources from a base station and identifies interference cleaning data based on the pilot resource. The UE then determines whether a first interference affecting the pilot resource is the same as a second interference affecting the data resource. When the first interference is the same as the second interference, the UE applies the interference cleaning data to the data resource. Otherwise, when the first interference is different than the second interference, the apparatus applies a modified interference cleaning data to the data resource.
