Abstract: Mechanisms for directional channel occupancy monitoring for a frequency band among multiple networks are provided. In one aspect, a method of wireless communication includes monitoring, in a shared frequency band in a plurality of beam directions, for signals associated with one or more wireless networks different from the first wireless network. The monitoring includes: detecting, in the shared frequency band and in at least a first beam direction of the plurality of beam directions, a first signal associated with a second wireless network; and up-dating a channel occupancy list to indicate that at least a portion of the shared frequency band is occupied in at least the first beam direction. The method also includes transmitting, in the shared frequency band, a second signal in a second beam direction of the plurality of beam directions based on the channel occupancy list.

Abstract: Wireless communications systems and methods related to multiplexing a sidelink-synchronization signal block (S-SSB) transmission with a physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) transmission for occupancy channel bandwidth (OCB) fulfilment are provided. A user equipment (UE) determines a multiplex configuration for multiplexing a sidelink transmission with a S-SSB transmission in a sidelink bandwidth part (BWP).

Abstract: Wireless communication systems and methods related to configuration for user equipment (UE)-initiated channel occupancy time (COT) in a frame-based equipment (FBE) mode are provided. A user equipment (UE) receives, from a base station (BS), a configuration for the UE to initiate a COT in an FBE mode. The configuration indicates a first FBE frame period. The UE initiates the COT in a first FBE frame having the first FBE frame period. The UE transmits, to the BS during the COT, an uplink communication signal.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode, at a layer two (L2) layer of the transmitting device, a set of service data units (SDUs) according to a set of network coding parameters to obtain a first set of protocol data units (PDUs). The transmitting device may transmit, to one or more receiving devices, the first set of PDUs. The transmitting device may receive, from a receiving device of the one or more receiving devices, a report indicating an SDU of the set of SDUs that was unsuccessfully received at the receiving device. The transmitting device may transmit, to the one or more receiving devices, based at least in part on the received report, a second set of one or more PDUs corresponding to at least the SDU of the set of SDUs.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using sidelink resources allocated in an unlicensed spectrum. A method that may be performed by a first UE includes establishing a connection with a second UE for sidelink communication in an unlicensed spectrum and communicating with the second UE via the connection using one or more sidelink sub-channels in the unlicensed spectrum according to a mapping between sidelink sub-channels and resource block (RB) sets of the unlicensed spectrum, wherein the unlicensed spectrum comprises a plurality of RB sets and one or more guard bands disposed between RB sets in the plurality RB sets.

Abstract: Aspects presented herein may enhance the determination of ED threshold to improve the channel access probability of the UE and the base station. In one aspect, a UE or a base station determines an ED threshold for a transmission, where the ED threshold is based on a characteristic of the transmission, a channel, or the UE/base station excluding a maximum transmit power of the UE or the base station. The UE or the base station determines whether an energy on the channel is less than the determined ED threshold. The UE or the base station transmits on the channel when the energy is determined to be less than the ED threshold.
