Communication protection method for sensing commmunication and updating or skipping updating a NAV accordingly, and apparatus therefor

In the present disclosure, an access point obtains a current network feature and generates a matching rule and an access rule, so that a station performs uplink access according to the matching rule and the access rule. This resolves a prior-art problem of reduced quality of service of a high-priority service because in an EDCA protocol, when there are relatively many low-priority service nodes, the high-priority service has difficulty in obtaining a resource through contention, or a conflict occurs between a low-priority packet and a high-priority packet. Effects of ensuring quality of service and user experience are achieved.
