Abstract: Wireless communications systems and methods are provided. A method of wireless communication may include performing a first listen-before-talk (LBT) procedure associated with a channel, wherein a channel occupancy time (COT) for the channel is acquired based on the first LBT being successful, communicating a first communication signal in a first link direction during the COT, switching from the first link direction to a second link direction different from the first link direction, and communicating after the switching, a second communication signal in the second link direction without performing a second LBT.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for physical uplink control channel (PUCCH) resource configuration. In one aspect, a base station may schedule a user equipment (UE) for PUCCH transmission based on a time division orthogonal cover code (TD-OCC) or a set of TD-OCCs, a cyclic shift step size or a set of cyclic shift step sizes, a first symbol or a set of first symbols, or a cyclic shift set. The base station may distinguish communications from that UE based on the TD-OCC or set of TD-OCCs, the cyclic shift step size or set of cyclic shift step sizes, the first symbol or set of first symbols, or the cyclic shift set.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.
