Abstract
A mobile station in a CDMA wireless communication system, includes a receiver which receives power-control data by which power for transmitting a wireless signal is controlled, from a plurality of base stations during soft handover, a judging unit which judges tendency in accordance with which the power-control data varies, in accordance with predetermined standard, and a masking unit which masks the power-control data, based on the results transmitted from the judging unit.
Claims20
A mobile station in a CDMA wireless communication system, comprising:
- a receiver which receives power-control data by which power for transmitting a wireless signal is controlled, from a plurality of base stations during soft handover;
- a judging unit which judges tendency in accordance with which said power-control data varies, in accordance with predetermined standard;
- and
- a masking unit which masks said power-control data, based on the results transmitted from said judging unit.
A mobile station in a CDMA wireless communication system, wherein if tendency in accordance with which power-control data by which power for transmitting a wireless signal is controlled varies in each of base stations during soft handover is identical with predetermined tendency, said power-control data transmitted from a base station or base stations exhibiting said tendency is not used for controlling power for transmitting a wireless signal.
A mobile station in a CDMA wireless communication system, wherein a plurality of base stations over which a mobile station moves in soft handover is grouped into a first group which meets predetermined requirements and a second group which does not meet predetermined requirements, and power-control data by which power for transmitting a wireless signal is controlled, transmitted from a base station or base stations belonging to said second group is not used for controlling power for transmitting a wireless signal.
A mobile station in a CDMA wireless communication system, wherein among power-control data by which power for transmitting a wireless signal is controlled, transmitted from a base station or base stations, only power-control data meeting said predetermined requirements is used for controlling power for transmitting a wireless signal, during soft handover.
An apparatus for controlling power for transmitting a wireless signal in a CDMA wireless communication system, wherein power-control data by which power for transmitting a wireless signal is controlled, transmitted from a base station or base stations for soft handover, is grouped into a first group which meets predetermined requirements and a second group which does not meet said predetermined requirements, and power-control belonging to said second group is not used for controlling power for transmitting a wireless signal.
A method of controlling power for transmitting a wireless signal in a CDMA wireless communication system, comprising:
- (a) receiving power-control data by which power for transmitting a wireless signal is controlled, from a plurality of base stations while a mobile station is in soft handover;
- (b) judging tendency in accordance with which said power-control data varies, in accordance with predetermined standard;
- and
- (c) controlling said power-in accordance with said tendency.
A program for causing a computer to carry out a method of controlling power for transmitting a wireless signal in a CDMA wireless communication system, steps executed by said computer in accordance with said program including:
- (a) receiving power-control data by which power for transmitting a wireless signal is controlled, from a plurality of base stations while a mobile station is in soft handover;
- (b) judging tendency in accordance with which said power-control data varies, in accordance with predetermined standard;
- and
- (c) controlling said power in accordance with said tendency.
