Title
(EN) NEW RADIO-UNLICENSED (NR-U) CHANNEL RESERVATION AT SLOT BOUNDARY
(FR) RÉSERVATION DE CANAL DE NOUVELLE RADIO SANS LICENCE (NR-U) AU NIVEAU D'UNE LIMITE DE CRÉNEAU
Abstract
(EN)
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.

L'invention concerne des systèmes et des procédés de communication sans fil relatifs aux réservations de canal et à la surveillance de canal dans un canal partagé par de multiples entités d'exploitation de réseau. Un premier dispositif de communication sans fil transmet une première configuration indiquant un premier ensemble d'occasions de surveillance de canal pour un canal. Chaque occasion de surveillance de canal du premier ensemble d'occasions de surveillance de canal est alignée avec un début d'un créneau de transmission. Le premier dispositif de communication sans fil transmet, sur la base d'un premier signal d'écoute avant de parler (LBT) dans le canal, un premier signal de réservation de canal afin de réserver une première opportunité de transmission (TXOP) dans le canal, le premier signal de réservation de canal transmis pendant une première occasion de surveillance de canal du premier ensemble d'occasions de surveillance de canal qui se trouve à l'intérieur de la première TXOP. Le premier dispositif de communication sans fil communique, avec un second dispositif de communication sans fil, un premier signal de communication dans un canal pendant la première TXOP
