Abstract

本发明实施例涉及无线通信领域，尤其涉及一种无线局域网数据传输方法及装置，用以提高数据传输效率。本发明实施例的方法包括：AP构造的PPDU中的PLCP头域中的控制域承载有所述AP的标识信息、持续时间信息、至少一个STA的标识，如此，STA可仅解析PLCP头域的控制域即可获得AP的标识信息、持续时间信息、至少一个STA的标识，从而STA可判断出该PPDU控制域中是否包含自身STA的标识，以及通配的STA标识，进一步的STA判断出该PPDU控制域中未包含自身的STA以及通配的STA标识，该STA则依据所述持续时间信息配置NAV，此过程仅解析了PPDU的控制域，从而提高了数据传输效率。
