Methods of power overload control in communication systems
First Claim
1. A method of performing power overload control in a communication system, comprising:
- estimating a loading of a given cell in the system;
dividing the estimated load into one or more load areas, each load area associated with a given target block error rate (BLERtarget);
providing an adjustment to BLERtarget based on a given evaluated load area to control transmit power of users in the cell so as to prevent a power overload condition in the system.

Abstract
Methods of providing power overload control in a communication system having a least one base station serving one or more users of at least one cell are described which may avoid an overload condition in the system. In one aspect, a target signal-to-interference ratio (SIRtarget) may be controlled for inner loop power control implemented by the base station, so as to maintain the loading of the communication system below an overload condition. In another aspect, a target block error rate (BLERtarget) may be controlled for outer loop power control implemented by the base station, so as to maintain the loading of communication system below an overload condition.

6. A method of providing power overload control in a communication system having a least one base station serving one or more users of at least one cell, comprising:
-
estimating a load of a cell in the communication system; dividing the estimated load into a plurality of load areas; assigning a first target block error rate (BLERtarget) to each load area determined as a low load area based on the divided estimated load associated with a respective load area; assigning a second BLERtarget to each load area determined as a high load area based on the divided estimated load associated with a respective load area, the first BLERtarget having a value lower than that of the second BLERtarget; controlling a target BLERtarget for outer loop power control implemented by the base station based on the assigned first BLERtarget and assigned second BLERtarget so as to maintain the loading of the communication system below an overload condition. - View Dependent Claims (7, 8)
