Claim of US Patent No. 10,219,258

1. An uplink service transmission method for use in an orthogonal frequency division multiple access (OFDMA) system, the method comprising:dividing, by a wireless local area network access point according to a quantity of stations connected to the access point, an entire channel on which the access point is located into multiple resource blocks, comprising:
determining, by the access point according to the quantity of the stations, a quantity of the resource blocks on the entire channel on which the access point is located,
evenly allocating, by the access point, data subcarriers to each of the resource blocks according to the quantity of the resource blocks and a quantity of the data subcarriers on the entire channel on which the access point is located, and
allocating, by the access point, a pilot to each of the resource blocks;
allocating, by the access point to each of the stations according to channel estimation information of the stations, a resource block for transmitting uplink information; and
separately sending, by the access point, channel allocation indication information to each of the stations for indicating information about the resource block allocated to each of the stations.
