Abstract: Certain aspects of the present disclosure provide techniques for channel access in an unlicensed spectrum. An example method of wireless communication by a user equipment includes receiving a resource grant indicating a plurality of resource candidates for an uplink signal. The method also includes sensing for energy, in response to the resource grant, over one or more of the resource candidates in a first sensing occasion before a transmission occasion of the uplink signal. The method further includes transmitting, during the transmission occasion, the uplink signal using a subset of the resource candidates selected based at least in part on energy sensed in the first sensing occasion.

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, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of multiple sets of linked physical downlink control channel (PDCCH) candidates if some PDCCH candidates of the multiple sets of linked PDCCH candidates occupy a same set of resources. In one aspect, the UE may select to monitor one of the PDCCH candidates that occupy the same set of resources in accordance with a prioritization rule. Upon selecting one of the PDCCH candidates that occupy the same set of resources for monitoring by the UE, the UE and the component of the BS may select a reference PDCCH candidate for one or more of the multiple sets of PDCCH candidates in accordance with a reference selection rule.
