METHODS AND EQUIPMENT FOR RESTORING ACCESS TO COMMUNICATION OPPORTUNITIES, EQUIPMENT, AND COMPUTER-READABLE STORAGE MEDIA

Abstract

The invention relates to the field of wireless communication, and specifically to a method for restoring the right to use a transmission opportunity, and the equipment involved. This method comprises the following steps: A first device receives the first frame from a second device. The first device restores the right to use the transmission opportunity (Transmission Opportunity TXOP) based on the first frame. The first frame indicates that the second device has ceased using the first time resource. This first time resource is allocated by the first device to the second device from the TXOP obtained using a single-user activation frame. According to the methods of the invention, the first frame can indicate that the second device has ceased using the allocated time resource (first time resource), so that the first device can withdraw / restore the right to use the TXOP based on the indication of the first frame. This could improve the utilization of large resources and the reliability of TXOP access recovery.The device for restoring access rights using transmission opportunities, communication equipment, communication systems, and vertical storage media, which are also revealed by the machine, is also disclosed.
