AI Technical Summary
Technical Problem
Existing WLAN technologies face challenges in reducing traffic collisions and transmission delays, particularly for high-priority traffic, due to methods like CSMA/CA and EDCA, which can lead to unfair access and longer delays.
Method used
A channel access method that reserves specific time-frequency resources for priority traffic, allowing exclusive access and scheduling, while also reserving non-overlapping resources for other traffic types, with adjustments based on delay requirements and traffic volume.
Benefits of technology
This approach enhances channel access efficiency by increasing opportunities for priority traffic, reducing transmission delays, and optimizing resource utilization, while minimizing interference and waste.

Abstract
A channel access method and communication device are provided. [Solution] The method includes the steps of: a first access point sending a management frame to a first device; and initiating channel access on at least one first reserved resource and transmitting first traffic. The management frame includes first instruction information, which indicates at least one first reserved resource on which the first traffic is permitted contention-based access, and the at least one first reserved resource includes only time-frequency resources reserved for the first traffic. The at least one first reserved resource is reserved specifically for the first traffic. In this way, the opportunities for the first traffic to access the channel are increased and the transmission delay of the first traffic is reduced.
