| 摘要 |
The invention relates to a method and system for simultaneous transmission of data from two or more wireless communication device during a transmission opportunity (TXOP) otherwise reserved for a single communication device in a network employing CSMA/CA. The invention proposes collaboration among the group of communication devices to reserve, via a request-to-send (RTS) frame, a transmission opportunity on a composite channel comprising of a plurality of sub-channels for the entire group and to efficiently manage allocation of the sub-channels for simultaneous data transmission from two or more devices. In the main aspect of the invention, the collaboration takes the form of grouping the sub-channels in the reserved composite channel so as to allow two or more stations to transmit data simultaneously over a contiguous frequency band. The collaboration among the group of communication devices may be in a managed or an ad hoc mode. The invention is particularly relevant to the IEEE 802.11ac communication standard. |
