Title:
WIRELESS COMMUNICATION METHOD AND APPARATUS, AND STATION AND ACCESS POINT
Document Type and Number:
WIPO Patent Application WO/2022/222488
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a wireless communication method and apparatus, and a station and an access point. The method comprises: an access point sending a first-type trigger frame to a station, wherein the first-type trigger frame is used for triggering uplink orthogonal frequency division multiple access based random access (UORA) of a first-type station and a second-type station; the station acquiring the first-type trigger frame from the access point; the station sending a second-type physical layer protocol data unit to the access point by means of UORA; and the access point acquiring the second-type physical layer protocol data unit from the station. Since the station is a first-type station, the first-type station chooses to send a second-type PPDU, thereby facilitating the prevention of a collision with data which is sent by a second-type station. In addition, since it is not necessary to isolate resources for bearing the second-type PPDU sent by the first-type station from resources for bearing the second-type PPDU sent by the second-type station, it is conducive to improving the resource utilization rate.
