Methods and devices for setting RoT limit

摘要

Methods and devices to dynamically determine suitable cell-specific RoT limits are provided. The suitable cell-specific RoT limits can advantageously be set both with respect to a short time scale and a long time scale In accordance with some embodiments the long term time scale operation is based on UE measurements representative for the intended coverage area of the cell. In accordance with some embodiments the short term time scale operation is based on UE measurements from active User Equipments only. Furthermore, also receiver capabilities of and cell isolation to neighboring base stations can be considered in the long time scale operation.

1. A method in a node of a cellular radio system of setting a Rise over Thermal (RoT) limit for a cell of the cellular radio system, the method comprising:
obtaining a plurality of measurements from a number of user equipment's within the cell collected during a long time period and a short time period, the long time period being used for obtaining the plurality of measurements associated with the number of user equipment's in a coverage area of the cell, the short time period being used for obtaining the plurality of measurements associated with active user equipment's within the cell; and dynamically setting the RoT limit within a range, wherein the range is determined based on the obtained plurality of measurements collected during the long time period and the short time period.
