Abstract:
1. The method of determining a cell isolation factor is used as a basis for determining whether to employ a radio resource management scheme or not, said radio resource management scheme including one or more of: exchanging with one or more base stations serving the at least one neighbouring cell, a High Interference Indicator, HII, referring to uplink resource allocations for cell edge terminals in the first cell, exchanging with one or more base stations serving the at least one neighbouring cell, an Overload Indicator, OI, referring to uplink interference experienced in the first cell, exchanging with one or more base stations serving the at least one neighbouring cell, a Relatively Narrow band Transmission Power Indicator, RNTPI, referring to restrictions in downlink power, applying Fractional Frequency Reuse, FFR, for cell edge terminals in the first cell in coordination with a predetermined set of neighbouring cells, applying Start Index or Random Start Index in coordination with a predetermined set of neighbouring cells, applying Interference Rejection Combining, IRC, in the base station's receiver for suppressing interference, and applying antenna tilt at the base station to reduce uplink interference.
