1. A method for resource scheduling in a wireless local area network, comprising:
generating, by an access point, based on predefined resource units, RUs, for a frequency domain resource, resource scheduling information for the frequency domain resource, wherein each of the predefined RUs is associated with a size and a location, the size being indicative of a quantity of subcarriers included in a predefined RU of the predefined RUs and the location being indicative of where the predefined RU is located in a bandwidth of the frequency domain resource,
wherein the bandwidth of the frequency domain resource comprises a 20-MHz frequency channel, and the resource scheduling information comprises a bits-sequence corresponding to the 20-MHz frequency channel in the bandwidth of the frequency domain resource, wherein the bits-sequence is indicative of an allocation of one or more of the predefined RUs corresponding to the 20-MHz frequency channel, wherein the allocation comprises a size and a location of each RU corresponding to the 20-MHz frequency channel, and the bits-sequence is indicative of a number of stations scheduled on each RU indicated by the bits-sequence,
wherein the resource scheduling information indicated by the bits-sequence corresponds to one of the following:
if an allocated RU is smaller than a predefined smallest size that supports multi-user multiple-input multiple-output, MU-MIMO, the number of stations scheduled on the allocated RU is a default value 1, or
if an allocated RU is not smaller than the predefined smallest size that supports MU-MIMO, the number of stations scheduled on the allocated RU is a number indicated by the bits-sequence, and
wherein the method further comprises sending, by the access point, the resource scheduling information.
