System and Method for OFDMA Resource Management in WLAN

摘要

Embodiments are provided for implementing a control function in a Wireless Local Area Network (WLAN) for allocation of resources to multiple stations (STAs) to enable Orthogonal Frequency Division Multiple Access (OFDMA) communications. An embodiment method includes determining a plurality of transmission resources for OFDMA communications of a plurality of STAs in the WLAN. The determination includes allocating a plurality of subcarriers to the STAs. The method further includes signaling the determined transmission resources to the STAs. The signaling of the transmission resources is piggybacked on at least one of data and management frames, such as in a sub-header of a MAC frame, or is an explicit signaling, such as in one or more dedicated fields of a traffic specification information element. The transmission resources for OFDMA communications allow simultaneous transmissions of the STAs in the WLAN.
