Abstract:
1. A method of communicating over multiple sub-channels of a wireless local area network comprising: sending a control message that is not combined with a data message from a first network entity to a second network entity, said control message to facilitate sequencing of wireless transmissions among at least two entities in a wireless network; receiving the control message at the second network entity and obtaining channel state information CSI from the received control message; using the CSI to determine that a capacity of a first sub-channel of the wireless network is greater than a capacity of a second sub-channel of the wireless network; dividing a data message to be sent into at least a first data message segment defining a first data segment size and a second data message segment defining a smaller second data segment size, said first and second data segment sizes based on the relative capacities of the first and second sub-channels; and in response to receiving the control message, sending from the second network entity the first data message segment over the first sub-channel, and the second data message segment over the second sub-channel.
