Radio-unlicensed (NR-U) channel reservation at slot boundary

Abstract:

Wireless communications systems and methods related to channel reservations and channel monitoring in a channel shared by multiple network operating entities are provided. A first wireless communication device transmits a first configuration indicating a first set of channel monitoring occasions for a channel. Each channel monitoring occasion of the first set of channel monitoring occasions is aligned to a start of a transmission slot. The first wireless communication device transmits, based on a first listen-before-talk (LBT) in the channel, a first channel reservation signal to reserve a first transmission opportunity (TXOP) in the channel, the first channel reservation signal transmitted during a first channel monitoring occasion of the first set of channel monitoring occasions that is within the first TXOP. The first wireless communication device communicates, with a second wireless communication device, a first communication signal in the channel during the first TXOP.
