A method and a system for controlling access to a medium in a wireless communication system are provided. A superframe structure is defined in time domain to include a contention free period (CFP) which has at least one scheduled resource allocation (SRA), at least one management SRA (MSRA), and a contention period. An extended beacon (EB) including information about the SRA and the MSRA is transmitted. The MAC architecture reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic, and is more efficient for real time (RT) traffic while maintaining full compatibility. [Reference numerals] (100) MAC architecture; (105) Resource coordination function (RCF); (115) Point coordination function (PCF); (120) Enhanced distributed channel access (EDCA); (125) Hybrid coordination function (HCF) controlled channel access; (130) RCF management channel access (RMCA); (135) RCF scheduled channel access (RSCA); (AA) Required for non-802.1n STAs, otherwise optional; (BB) MAC extent; (CC) Required for management function; (DD) Required for scheduled access with QoS; (EE) Use for contention services, basis for PCF, HCF, RCF |
