Abstract
Channel reservation in time division duplex for devices in systems involving, for example user devices and access points, may be accomplished using channel reservation request messages, such as request-to-send (RTS) messages and channel reservation grant messages, such as clear-to-send (CTS) messages. A method for channel reservation may include preparing a frame including at least one channel reservation request message and at least one channel reservation grant message. The preparing may include multiplexing the at least one channel reservation request message and the at least one channel reservation grant message at least by frequency-division multiplexing. The method may also include transmitting the frame from a first node to a second node, wherein the channel reservation request message and the channel reservation grant message relate to communications between the first node and the second node.
