Abstract:
1. A wireless communication method in a communication system in which an access point achieves packet communications with a plurality of user terminals under the SDMA (Space Division Multiple Access) scheme, comprising the steps of: a first step of predicting transmission time durations necessary for transmitting a plurality of transmission packets destined to a plurality of user terminals to which parallel data transmission is performed in one slot under the SDMA scheme; a second step of determining, on the basis of said predicted transmission time durations for said plurality of transmission packets, a transmission parameter for said transmission packets to be transmitted in said one slot, the transmission parameter being a data size per one transmission frame; and a third step of aggregating packets that share a same destination from the plurality of transmission packets to generate transmission frames to be transmitted in said one slot to said plurality of user terminals on the basis of said determined transmission parameter, adding control information to a header of each transmission frame indicating that the transmission frame includes the aggregated packets of the transmission frame, and transmitting said transmission frames.
