Uplink service transmission method and apparatus and wireless local area network access point

A wireless local area network access point for use in an orthogonal frequency division multiple access (OFDMA) system, the access point comprising:

• a processor configured to:
• divide, 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,
• determine, 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 allocate 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,
• allocate a pilot to each of the resource blocks, and
• allocate, to each of the stations according to channel estimation information of each of the stations, a resource block for transmitting uplink information;
• and
• a transmitter configured to separately send channel allocation indication information to each of the stations for indicating information about the resource block allocated to each of the stations, to enable each of the stations to run in parallel by using the resource block corresponding to each of the stations.

An uplink service transmission apparatus for use in an orthogonal frequency division multiple access (OFDMA) system, the apparatus comprising:

• a processor;
• and
• memory configured to store instructions that, when executed by the processor, cause the apparatus to:
• divide, according to a quantity of stations connected to an access point, an entire channel on which the access point is located into multiple resource blocks,
• determine, 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 allocate 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,
• allocate a pilot to each of the resource blocks,
• allocate, to each of the stations according to channel estimation information of each of the stations, a resource block for transmitting uplink information, and
• separately send channel allocation indication information to each of the stations for indicating information about the resource block allocated to each of the stations, to enable each of the stations to run in parallel by using the resource block corresponding to each of the stations.
