    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device allocated two sets of non-contiguous frequency domain resources may divide a set of modulation symbols associated with a codeword into two subsets of modulation symbols. The wireless device may map the two subsets of modulation symbols into two sets of pre-discrete Fourier transform (DFT) resource elements (REs). The wireless device may pad the pre-DFT REs according to a block based scheme or a comb based scheme. The wireless device may perform a first DFT on the first set of pre-DFT REs and a second DFT on the second set of pre-DFT REs to generate first and second sets of frequency domain samples. The wireless device may perform an inverse fast Fourier transform on the first and second sets of frequency domain samples to generate a time domain waveform that may have a low peak to average power ratio.

    Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARD) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to long term sensing based inter-operator coexistence techniques for unlicensed high bands providing a measurement framework and candidate measurements, along with channel selection, per-beam channel deselection, and dynamic frequency selection. In one aspect, a network entity may determine that a non-coordinating node satisfies a communication presence threshold based on the at least one long term sensing measurement, and transmitting, to a user equipment (UE), an indication of a remedial action, or adjusting the communication channel based on the determination. In another aspect, a UE may obtain at least one long term sensing measurement, and transmit a long term sensing report including the at least one long term sensing measurement.

    Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may configure power parameters for sidelink communications between user equipments (UEs). The power parameters may be configured based on the UEs operating within an AP service area. In some examples, an AP may transmit one or more signals to the first UE, and the first UE may determine the power parameters based on receiving the signals. Additionally or alternatively, the first UE may be configured to transmit one or more reference signals to the AP, and the AP may configure the power parameters based on receiving the reference signals. The first AP may indicate the power parameters in a sidelink configuration transmitted to the first UE. The first UE may communicate with the second UE on a sidelink channel in accordance with the sidelink configuration, which may improve efficiency and reliability of the sidelink communications.
