摘要:
A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels, between the first cell region and at least a second cell region. The invention has a particular advantage in TDD mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.
