PROCEDURE FOR POWER SAVE MULTI-POLL(PSMP) IN A VERY HIGH THROUGHPUT(VHT) WIRELESS LOCAL ACCESS NETWORK SYSTEM, PSMP FRAME FORMAT FOR THE PROCEDURE, AND STATION SUPPORTING THE PROCEDURE

摘要

PURPOSE: A power save multi-pole procedure in the VHT wireless LAN system for improving the efficiency of the whole radio resource is provided to perform downlink transmission or uplink transmission in multiple STAs by allocating more than one sub channels to the multiple STAs. CONSTITUTION: An STA 1(Station1) converts the wakeup state to the DTT 1(Downlink Transmission Time 1). The STA1 receives an MPDU(MAC((Media Access Control) Protocol Data Unit)) from the VHT(Very High Throughput) AP(Access Point) and Multi-TID block receipt confirmation request frame(MTBA Req(Block ACK. Request frame)). The STA1 enters to the doze state. The STA2 converts into the state waken up due to DTT2. The STA2 receives an A-MPDU and Multi-TID block receipt confirmation request frame from the VHT AP. The STA2 enters to the doze state.
