Abstract  Abstract

Because the common E-DCH resource is allocated from a single node B can it perhaps is not possible between the adjacent node B uplink macro-diversity. In addition common E-DCH resources are allocated to the user equipment (UE) may not be allowed to perform cell reselection. Therefore for example when the UE moves to closer to the control by the non-service node B adjacent to the cell position is maintained when the common E-DCH resource allocated to a given UE will cause no more than hundreds of milliseconds acceptable inter-cell interference. In order to overcome the inter-cell interference and allows the Cell-FACH state more widely used method can be used for detecting and/or controlling inter-cell interference.

Since common E-DCH resources may be assigned from a single Node B uplink macro-diversity may not be possible between neighboring Node Bs. In addition a user equipment (UE) assigned a common E-DCH resource may not be allowed to perform cell reselection. Thus maintaining the assignment of a common E-DCH resource to a given UE for more than a few hundred milliseconds may result in unacceptable inter-cell interference for example when the UE moves closer to a neighboring cell controlled by a non-serving Node B. To overcome inter-cell interference and allow a more extensive utilization of the Cell_FACH state a method may be used to detect and/or control inter-cell interference.
