Abstract

A method of allocating frequency channels in a wireless communication system comprising common channel framework enabled stations, said method comprising: —using by said common channel framework enabled stations a common frequency channel at common time intervals in order to determine a communication frequency channel on which a pair of common channel framework enabled stations will be allowed to exchange data frames, —periodically changing the common frequency channel at the beginning of each common time interval.

Claims (10)

1. A method of allocating frequency channels in a wireless communication system comprising common channel framework enabled stations, comprising:

using by said common channel framework enabled stations a common frequency channel at common time intervals in order to determine a communication frequency channel on which a pair of common channel framework enabled stations will be allowed to exchange data frames, and

periodically rotating the common frequency channel at the beginning of each beacon interval according to a rotation cycle within a set of available frequency channels.

2. The method of claim 1 , further comprising:

determining an occupancy level of a frequency channel during the common time interval when said channel is used as the common frequency channel.

3. The method of claim 1 , further comprising:

storing the occupancy levels of the different frequency channels successively used as the common frequency channel, and

selecting the communication frequency channel on which a pair of common channel framework enabled stations will be allowed to exchange data frames among the frequency channels having one of the lowest occupancy level.

4. A common channel framework enabled station for use in a wireless communication system comprising:

a transceiver for tuning to a common frequency channel at common time intervals in order to determine a communication frequency channel on which said common channel framework enabled station will be allowed to exchange data frames with another common channel framework enabled station, the common channel framework enabled station for rotating the common frequency channel at the beginning of each beacon interval according to a rotation cycle within a set of available frequency channels.
