Abstract
In an uplink service transmission method, an access point divides an entire channel into resource blocks according to a quantity of stations that are connected to the access point, then allocates, to each station according to channel estimation information of each station, a resource block used to transmit uplink information, and separately sends channel allocation indication information to each station, so that each station finds, according to the channel allocation indication information, the resource block corresponding to the station, and transmits the uplink information by using the resource block, so as to implement that in an OFDMA system, multiple stations transmit uplink information in parallel, that is, resource blocks that are obtained by means of division can be simultaneously applicable to multiple stations.
