Title: DATA TRANSMISSION METHOD AND APPARATUS
Abstract:
Disclosed in the present invention are a data transmission method and apparatus, relating to the field of wireless communication technology. The method comprises: acquiring from a channel data frames of other BSS transmission; on the basis of the information carried in the data frames, determining whether to enable spatial reuse transmission; and when deciding to enable spatial reuse transmission, using thresholds competitively on the channel to implement spatial reuse transmission; the problem of low data throughput and the low opportunity of communication for STA located in an OBSS region is resolved, and whether or not spatial reuse can be enabled is determined by means of existing information only, without the need to add additional information to transmitted data packets, thus saving STA energy and improving the opportunity for spatial reuse.
