Abstract
A power control method during a soft handoff in a mobile communication system. A mobile station communicating with a plurality of base stations at a soft handoff measures the signal strengths of forward common pilot channels received from the base stations and transmit them to the base stations sequentially. Then the base stations control the transmission power of forward common power control channels according to the received signal strength measurements.
Claims15
A method of transmitting signal strength measurements of forward channels received from a plurality of base stations communicating with a mobile station at a soft handoff to the base stations from the mobile station in a mobile communication system, comprising the steps of:
- assigning a time slot to each base station;
- and
- transmitting the signal strength measurements corresponding to each base station during its assigned time slot respectively,
- wherein an indicator indicating a base station having the highest signal strength among the base stations is transmitted in the transmitting step.
A method of transmitting signal strength measurements of forward channels received from a plurality of base stations communicating with a mobile station at a soft handoff to the base stations from the mobile station in a mobile communication system, comprising the steps of:
- receiving information defining a time slot assigned to each base station from a service base station among the base stations;
- and
- transmitting the signal strength measurements corresponding to each base station during its assigned time slot respectively,
- wherein an indicator indicating a base station having the highest signal strength among the base stations is transmitted in the transmitting step.
A signal strength measurement transmitting method in a mobile station communicating with a plurality of base stations at a soft handoff in a mobile communication system, comprising the steps of:
- measuring signal strengths of forward channels received from the base stations respectively;
- and
- transmitting the signal strength measurements corresponding to the base stations, sequentially,
- wherein an indicator indicating a base station having the highest signal strength among the base stations is transmitted in the transmitting step.
A signal strength measurement receiving method for a forward power control in a service base station among a plurality of base stations communicating with a mobile station at a soft handoff in a mobile communication system, comprising the steps of:
- assigning a time slot to each base station;
- transmitting information about the time slot assignment to the other base stations;
- and
- receiving a signal strength measurement of a first forward channel from the mobile station in the time slot assigned to the service base station, said signal strength measurement includes signal strength measurements of each base station measured by the mobile station during the time slot assigned to each base station,
- wherein an indicator indicating a base station having the highest signal strength is received in the receiving step.
