Title (EN) TECHNIQUES FOR TRANSMITTING CHANNEL USAGE BEACON SIGNALS OVER AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND
(FR) TECHNIQUES DE TRANSMISSION DE SIGNAUX DE BALISE D'UTILISATION DE CANAL SUR UNE BANDE DE SPECTRE DE RADIOFRÉQUENCES SANS LICENCE
Abstract:
(EN) Techniques are described for wireless communication. A first method includes winning a contention for access to an unlicensed radio frequency spectrum band, and transmitting at least a portion of a channel usage beacon signal (CUBS) over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted in a number of frequency interlaces of the unlicensed radio frequency spectrum band. A second method includes winning a contention for access to an unlicensed radio frequency spectrum band; determining whether the contention is won within a threshold time before a next symbol period boundary; and transmitting at least a portion of a CUBS over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted during a preamble including a fractional period of a first symbol period. The at least portion of the CUBS may be based at least in part on the determining.
(FR) Cette invention concerne des procédés de communication sans fil. Un premier procédé consiste à remporter un conflit d'accès à une bande de spectre de radiofréquences sans licence, et à transmettre au moins une partie d'un signal de balise d'utilisation de canal (CUBS) au-dessus de la bande de spectre de radiofréquences sans licence. Ladite/lesdites partie(s) du signal CUBS est/sont transmise(s) dans un certain nombre d'entrelacements de fréquence de la bande de spectre de radiofréquences sans licence. Un deuxième procédé selon l'invention consiste à remporter un conflit d'accès à une bande de spectre de radiofréquences sans licence; déterminer si le conflit d'accès est remporté à l'intérieur d'un intervalle de temps seuil avant une prochaine limite de période de symbole; et transmettre au moins une partie d'un signal CUBS sur la bande de spectre de radiofréquences sans licence. Ladite/lesdites partie(s) de signal CUBS est/sont transmise(s) au cours d'un préambule comprenant période fractionnaire d'une première période de symbole. Ladite/lesdites partie(s) de signal CUBS peut/peuvent être basée(s) au moins en partie sur la détermination.
