Abstract
A method is provided for controlling power of radio links, particularly a method for controlling transmit power of a terminal in soft handover. This may include a process for setting transmit power control commands from each radio link according to quality of each radio link, and a process for setting a combined transmit power control command by confirming whether the transmit power control commands from each radio link are identical for all the radio links. The method for controlling power of the radio links may prevent reduction of reliability of the transmit power control commands in the process for deciding the transmit power control commands from different radio link sets to control the transmit power of the terminal in soft handover.
Claims24
A method for controlling power of radio links comprising:
- determining reliability of a plurality of radio links according to a quality of each radio link, the quality of each radio link being determined based on a signal to interference ratio (Eb/No);
- and
- setting a combined transmit power control command value based on the determined reliability of each of the plurality of radio links;
- wherein determining the reliability comprises:
- measuring the quality of each of the plurality of radio links;
- and
- comparing the measured quality of each radio link with a predetermined reference value,
- wherein when the quality of one radio link is greater than the reference value, determining the reliability includes setting the reliability of the one radio link to 1.
A method for controlling power of radio links in a mobile communication system comprising:
- measuring a quality of a radio link, the quality of each radio link being determined based on a signal to interference ratio (Eb/No);
- setting a reliability of the radio link based on the measured quality of the radio link;
- repeating measuring the quality of the radio link and setting the reliability of the radio link until the reliability of all the radio links ate set;
- and
- determining a combined transmit power control command value based on the reliability of each radio link.
A mobile communication system comprising:
- a processor device to determine a reliability of each of a plurality of radio links based on quality of each of the links and to set a transmit power control value based on the determined reliability of each radio link, the processor device determining the quality of each radio link based on a signal to interference ratio (Eb/No);
- and
- a transmitting device to transmit signals based on the set transmit power control value;
- wherein the processor device determines the reliability by measuring the quality of each radio link and comparing the measured quality of each radio link with a predetermined reference value;
- wherein when the quality of one radio link is greater than the reference value, the processor device sets the reliability of the one radio link to 1.
