Abstract

Embodiments of a wireless communication system and methods allocating bandwidth are generally described herein. Other embodiments may be described and claimed. In some embodiments, an estimated requested bandwidth is included in a contention code. Additionally, a mobile station may reuse a previously used contention code that resulted in successful access to a base station. Further, a base station may determine or predict contention patterns and allocate codes based on the patterns.

Claims

1. A method comprising:

determining a plurality of subcode spaces within a contention code space, the subcode spaces having a subcode space identifier;

receiving a contention code, the contention code including the subcode space identifier; and

allocating an uplink resource for a data stream in accordance with the subcode space identifier.
