Abstract
(EN)
Wireless communications systems and methods related to communications with narrowband wireless communication devices over a wide frequency band are provided. A first wireless communication device transmits a first configuration indicating a first set of channel monitoring occasions for a first channel and a second set of channel monitoring occasions for a second channel. The first wireless communication device transmits, in the first channel based on at least a listen- before-talk (LBT) in the first channel, a first occupancy indication signal indicating a first transmission opportunity (TXOP) in the first channel. The first wireless communication device transmits, in the first channel based on the first configuration, a second occupancy indication signal associated with the first TXOP in the first channel during a channel monitoring occasion of the first set of channel monitoring occasions within the first TXOP.

L'invention concerne des systèmes de communication sans fil et des procédés se rapportant à des communications avec des dispositifs de communication sans fil à bande étroite sur une large bande de fréquences. Un premier dispositif de communication sans fil transmet une première configuration indiquant un premier ensemble d'occasions de surveillance de canal pour un premier canal et un second ensemble d'occasions de surveillance de canal pour un second canal. Le premier dispositif de communication sans fil transmet, dans le premier canal sur la base au moins d'une écoute avant transmission (LBT) dans le premier canal, un premier signal d'indication d'occupation indiquant une première opportunité de transmission (TXOP) dans le premier canal. Le premier dispositif de communication sans fil transmet, dans le premier canal sur la base de la première configuration, un second signal d'indication d'occupation associé à la première opportunité TXOP dans le premier canal pendant une occasion de surveillance de canal du premier ensemble d'occasions de surveillance de canal pendant la première opportunité TXOP.
