A system and method for authentication in a wireless mobile communication system are provided, in which a mobile station calculates a CMAC value having a first number of bits, transmits to a base station a ranging request message including a partial CMAC value being a second number of upper bits of the CMAC value having the first number of bits, and receives a ranging response message indicating whether authentication is successful or failed from the base station.
摘要:
A resource allocation method in a multicarrier communication system where a base station allocates resources to a plurality of mobile stations according to feedback channel information from the mobile stations. The base station receives a resource request message from each mobile station and selects a set of mobile stations offering a maximum system gain without overlapped resources at a specific point in time based on the resource request messages from all mobile stations in the system. The requested resources and then allocated to the selected mobile stations.
