Abstract: Embodiments provide resource scheduling methods and apparatus that reduce transmission resource overhead in resource scheduling. The method can be applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units potentially allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence to indicate whether one or more of the resource unit locations potentially allocated for the to-be-assigned frequency domain resource are the actually allocated resource units.

Abstract: Embodiments of the present invention provide a data transmission method and a station. The method includes: transmitting, by a station, data of a primary access category (AC) of the station within a current transmission opportunity (TXOP), where to-be-transmitted data of the station includes the data of the primary AC and data of at least one secondary AC; after transmission of the data of the primary AC is completed, determining, by the station, whether there is remaining time in the TXOP; and if there is remaining time in the TXOP, transmitting, by the station, the data of the at least one secondary AC within the remaining time. According to the method provided in the embodiments of the present invention, the current TXOP is fully utilized without a channel resource wasted, thereby improving data transmission efficiency of the station.
