Title (EN) SPATIAL LISTEN-BEFORE-TALK (LBT) WITH CHANNEL VARIATION CONSIDERATION
(FR) ÉCOUTE AVANT DE PARLER (LBT) SPATIALE AVEC PRISE EN COMPTE D'UNE VARIATION DE CANAL
Abstract:
(EN) Wireless communications systems and methods related to considering channel variations for medium sharing in a spatial domain are provided. A first wireless communication device transmits one or more reservation response signals indicating spatial channel information in response to a reservation request for a transmission opportunity (TXOP) in a frequency spectrum. The first wireless communication device receives, from a second wireless communication device, a communication signal from a first spatial subspace during the TXOP based on the reservation request. In one embodiment, the first wireless communication device may repeat a transmission of the reservation response signal after transmitting a portion of the communication signal. In another embodiment, the first wireless communication device may include a channel variation parameter in the reservation response signal.
(FR) L'invention concerne des systèmes et des procédés de communication sans fil se rapportant à la prise en compte de variations de canaux pour le partage de supports dans un domaine spatial. Un premier dispositif de communication sans fil transmet un ou plusieurs signaux de réponse de réservation indiquant des informations de canal spatial en réponse à une demande de réservation pour une opportunité de transmission (TXOP) dans un spectre de fréquences. Le premier dispositif de communication sans fil reçoit, en provenance d'un second dispositif de communication sans fil, un signal de communication en provenance d'un premier sous-espace spatial durant la TXOP sur la base de la demande de réservation. Dans un mode de réalisation, le premier dispositif de communication sans fil peut répéter une transmission du signal de réponse de réservation après la transmission d'une partie du signal de communication. Dans un autre mode de réalisation, le premier dispositif de communication sans fil peut comprendre un paramètre de variation de canal dans le signal de réponse de réservation.
