Abstract:
1. A method operative in a system utilizing a Request-to-Send/Clear-to-Send (RTS/CTS) protocol and that utilizes a plurality of channels for data transfer, comprising: sending, by a first device, an RTS frame over the plurality of channels, wherein the RTS frame comprises information used to set a network allocation vector (NAV), wherein the NAV is set to a time amount that is computed based on a minimum bandwidth value and an amount of data to be sent by the first device to a second device over the minimum bandwidth; receiving, by the first device, a CTS frame from the second device over at least one of the plurality of channels; transmitting, by the first device, data to the second device within the time duration set by the NAV using the at least one of the plurality of channels; and if the first device completes transmission of data to the second device within a time duration corresponding to the NAV, outputting, over the at least one of the plurality of channels, a data completion signal that indicates the at least one of the plurality of channels is available for use by other devices on the network.
