Abstract
(EN)
Certain aspects of the present disclosure relate to a methods and apparatus for wireless communication. In one aspect, a method of communication over a wireless medium includes transmitting, from a first wireless device, a first communication reserving access to the wireless medium during a first time period. The method further includes transmitting or receiving a long term evolution unlicensed (LTE-U) transmission during the first time period. The method further includes detecting, prior to the first time period, an interfering WLAN transmission that will result in its transmitter and recipients not detecting the first communication. The method further includes transmitting, after the interfering WLAN transmission, a second communication reserving access to the wireless medium during a second time period at least partially overlapping the first.

Certains aspects de la présente invention concernent des procédés et un appareil pour la communication sans fil. Dans un aspect, un procédé de communication sur un support sans fil comprend la transmission, à partir d'un premier dispositif sans fil, d'une première communication réservant un accès au support sans fil pendant une première période de temps. Le procédé comprend en outre la transmission ou la réception d'une transmission par évolution à long terme non autorisée (LTE-U) pendant la première période de temps. Le procédé comprend en outre la détection, avant la première période de temps, d'une transmission WLAN de brouillage qui entraînera la non-détection de la première communication par son émetteur et ses destinataires. Le procédé comprend en outre la transmission, après la transmission WLAN de brouillage, d'une seconde communication réservant un accès au support sans fil pendant une seconde période de temps chevauchant au moins partiellement la première période de temps.
