Method and device for requesting and allocating bandwidths in wireless communication systems

A method, in a base station in a wireless telecommunication network, for allocating bandwidths for a mobile station, comprising:

• sending a first resource allocation notification message to said mobile station, said first resource allocation notification message comprising the time or frequency resource information of a time or frequency resource block on which each mobile station sends a bandwidth allocation request message randomly, said time or frequency resource block being shared by a plurality of mobile stations;
• receiving said bandwidth allocation request message from said mobile station on said time or frequency resource block on which each mobile station sends said bandwidth allocation request message randomly, said bandwidth allocation request message comprising bandwidth allocation request-related information;
• allocating base station time or frequency resources for said mobile station according to said bandwidth allocation request-related information, and generating a second resource allocation notification message, said allocated time or frequency resources being exclusively used by said mobile station;
• and
• sending said second resource allocation notification message to said mobile station.

An allocating apparatus, in a base station in a wireless telecommunication network, for allocating bandwidths for a mobile station, comprising:

• a second transmitter, configured to send a first resource allocation notification message to said mobile station, said first resource allocation notification message comprising the time or frequency resource information of a time or frequency resource block on which each mobile station sends a bandwidth allocation request message randomly, and said time or frequency resource block being shared by a plurality of mobile stations;
• a second receiver, configured to receive said bandwidth allocation request message from said mobile station on said time or frequency resource block on which each mobile station sends said bandwidth allocation request message randomly, said bandwidth allocation request message comprising bandwidth allocation request-related information;
• and
• an allocating and generating device configured to allocate time or frequency resources for said mobile station according to said bandwidth allocation request related information, and generate a second resource allocation notification message, said allocated time or frequency resources being exclusively used by said mobile station;
• wherein said second sending transmitter is further configured to send said second resource allocation notification message to said mobile station.
