Abstract
A method and system for cooperative transmission power control in a communication system is provided. The method, operating within a system having a base station and at least on mobile station, includes the step of providing a power control data structure having memory fields indexed according to a predetermined parameter set. The next step retrieves from one of the memory fields a transmission power control value and adjusts a transmission power level of the mobile station according to the retrieved value.
Claims20
A method for cooperative transmission power control in a communication system having a base station and a mobile station, the method comprising the steps of:
- providing a power control data structure, the power control data structure comprising memory fields indexed according to a predetermined parameter set;
- retrieving from one of the memory fields a transmission power control value;
- and
- using the retrieved one of the plurality of transmission power control values to adjust a transmission power level of the mobile station.
A system for controlling transmission power level of a plurality of mobile stations in a code division multiple access (CDMA) communication system having at least one base station, the system comprising:
- each mobile station comprising:
- a mobile station memory device for storing a plurality of mobile station transmission power values for the respective mobile station;
- a mobile station memory access controller for accessing the mobile station memory device;
- a mobile station memory controller for updating the mobile station memory device;
- and
- a base station memory controller for updating the plurality of mobile station transmission power values.
A method for controlling mobile station transmission power in a communications system, the communication system having a base station and a plurality of mobile stations, the method comprising the steps of:
- providing each mobile station a transmission power level look-up table;
- providing each mobile station an open-loop power control model;
- and
- accessing the transmission power level look-up table with the open-loop power control model.
