Abstract: front page image
(EN) Systems, devices, and methods are disclosed for determining one or more clear channel assessment occasions. Techniques include performing one or more clear channel assessment (CCA) processes on a channel during the one or more CCA occasions to determine whether the channel is available at the one or more CCA occasion based on the one or more CCA processes. Techniques include sending the UL transmission in one or more UL subframes via the channel on at least a condition that the channel is determined to be available at the one or more CCA occasions. Techniques include performing the one or moreCCA processes on the channel during another of the one or more CCA occasions on at least a condition that the channel is determined to be unavailable at a previous CCA occasion.
(ZH) 公开了用于确定一个或多个空闲信道评估时机的系统、设备和方法。技术包括在所述一个或多个CCA时机期间对信道执行一个或多个空闲信道评估(CCA)过程以基于该一个或多个CCA过程确定所述信道是否在所述一个或多个CCA时机可用。技术包括至少在所述信道被确定在所述一个或多个CCA时机可用的情况下经由所述信道在一个或多个UL子帧中发送UL传输。技术包括至少在所述信道被确定在之前CCA时机不可用的情况下,在一个或多个CCA时机的另一个CCA时机期间对所述信道执行所述一个或多个CCA过程。
