Improving Relay Operation In Wireless Networks

Abstract: improving relay operation in wireless networks may be provided. improving relay operation in wireless networks can include performing a relay transmit opportunity (txop) frame exchange with a relay station (rsta), wherein the txop frame exchange comprises setting a modulation and coding scheme (mcs) for a second hop frame the rsta will transmit to a destination sta (dsta). a first hop frame can be transmitted to the rsta for the rsta to transmit to the dsta via the second hop frame. then, an end-to-end acknowledge (ack) signal can be received from the rsta. relay operation can be improved by implementing an end-to-end ack, the tsta determining the txop duration, enabling the rsta to relay timing synchronization function (tsf) timing information to the dsta, and/or enabling the rsta to receive a transmission from the tsta and relay the transmission to the dsta simultaneously.
