Patent ID: 7505771

Claim:
A telecommunication method in a wireless cellular telecommunication system having a radio network controller and a base station, the base station supporting a first plurality of data channels and a second plurality of control channels for the data channels, the method comprising: receiving of a number of orthogonal variable spreading factor codes from the radio network controller by the base station, whereby the number of orthogonal variable spreading factor codes received from the radio network controller is a coherent code area, evaluating a load situation by the base station, in case the orthogonal variable spreading factor codes received from the radio network controller are insufficient for the load situation, requesting additional orthogonal variable spreading factor codes from the radio network controller by the base station, or in case it is determined by the base station that a higher load than the load situation can be handled by means of the orthogonal variable spreading factor codes received from the radio network controller a request is sent from the base station to the radio network controller in order to reduce the number of orthogonal variable spreading factor codes, and dividing the coherent code area into a coherent sub-area for the data channels and first and second sub-areas for the control channels, whereby the sizes of the coherent sub-area and the first and second sub-areas are selected by the base station depending on the load situation.
