SYSTEM AND METHOD FOR TRANSMITTING DATA IN A WIRELESS LAN MULTI-USER TRANSMISSION OPPORTUNITY

摘要

A method for communicating data carried in a frequency-division multiple access (OFDMA) data frame in a transmission opportunity (TXOP) of a wireless local area network (LAN) access point (AP) is provided. The OFDMA data frame may be a downlink or uplink multi-user (MU) OFDMA data frame carrying data associated with a plurality of stations in respective frequency sub-bands. Cascaded downlink and uplink MU OFDMA data frames may be communicated in the same TXOP. A downlink frame may be communicated in a TXOP to carry frequency resource allocation information for an uplink OFDMA data frame communicated in the TXOP. An acknowledgement (ACK) frame may be communicated in a TXOP to acknowledge whether a downlink or uplink MU OFDMA data frame in the TXOP was successfully received.
