The invention provides an optimum amount of desensitization to a RDS when it is necessary due to inter-cell interference. In this way, the amount of inter-cell interference created by RDS is reduced, while maintaining the uplink performance in RDS irrespective of any incoming neighbor cell interference. The invention therefore contributes to enhance the general mobile broadband performance for RDS. The advantages of the invention are illustrated in Figures 4 and 3. Note that the difference between Figures 3 and 4 is that, in Figure 4, when the invention detects a too high inter-cell interference, it starts to increase the thermal noise power floor by ΔPd (t). This is illustrated by the thick line that starts at the arrow marked "invention starts to add desensitization". Since the headroom for scheduling users in the RDS UL is counted with respect to the thick line, this headroom remains until soft handover takes place. Then the interfering UE changes to the RDS cell and the inter-cell interference problem disappears. |
