Abstract:
1. A cellular radio communications system comprising: a first radio communications equipment, located within a first cell, for communicating traffic with different characteristics, the traffic being divided into two or more categories including conventional communications and opportunistic communications which, transfer with different characteristics, wherein conventional communications comprise communications in which transmission power for various channels is adjusted to achieve at least minimum quality requirements and wherein opportunistic communications use scheduling and rate control to transfer traffic, the first radio communications equipment further comprising processing circuitry for allocating traffic transmissions that use conventional communications to physically wholly or partially separated channels to the traffic transmissions that use opportunistic communications; a second radio communications equipment, located within a second cell, for communicating traffic with different characteristics, the traffic being divided into two or more categories including conventional communications and opportunistic communications which transfer with different characteristics, wherein conventional communications comprise communications in which transmission power for various channels is adjusted to achieve at least minimum quality requirements and wherein opportunistic communications use scheduling and rate control to transfer traffic, the second radio communications equipment further comprising processing circuitry for allocating traffic transmissions that use conventional communications to physically wholly or partially separated channels to the traffic transmissions that use opportunistic communications; and processing circuitry configured to identify channels within the first cell and the second cell, analyze the identified channels to determine overlapping time slots, frequency slots or time-frequency slots that contain the different types of traffic in the identified channels, and allocate traffic of different characteristics of different cells by which allocation interference between differently characterized communications of neighboring cells is minimized, wherein the processing circuitry allocates the traffic of different characteristics of the different cells by minimizing a number of the time slots, the frequency slots or the time-frequency slots which overlap and contain different types of traffic that are transmitted from the first and second radio communications equipment in the different cells.
