METHODS AND PROCEDURES FOR SUB-CHANNELIZATION TRANSMISSION

摘要

Embodiments may allow for the use of orthogonal frequency-division multiple access (OFDMA) in IEEE 802.11 applications to improve system special efficiency and special utilization over legacy multiple access schemes. Embodiments may provide flexible resource allocation with a dynamic framing scheme (DFS) in multiple sub-channels using a station identification field (STA IDF). Embodiments also include the design of acknowledgement (ACK) signals that may be used in the dynamic framing scheme, although with methods to avoid interference among sub-channels and improve spectral efficiency.
