Abstract
A mobile terminal includes a receiving part configured to receive from a base station a reception signal including a control signal used for controlling transmission power; a comparing part configured to compare a correlation value, which is obtained from the control signal included in the reception signal and a first unique signal, with a threshold; a control part configured to control the transmission power based on a comparison result of the comparing part; and a threshold generating part configured to change the threshold according to a reception environment.
Claims19
A mobile terminal comprising:
- a receiving part configured to receive from a base station a reception signal including a control signal used for controlling transmission power;
- a comparing part configured to compare a correlation value, which is obtained from the control signal included in the reception signal and a first unique signal, with a threshold;
- a control part configured to control the transmission power based on a comparison result of the comparing part;
- and
- a threshold generating part configured to change the threshold according to a reception environment.
A power control method in a mobile terminal, comprising:
- receiving, from a base station, a reception signal including a control signal used for controlling transmission power;
- changing, according to a reception environment, a threshold used for comparing with a correlation value that is obtained from the control signal included in the reception signal and a first unique signal;
- comparing the correlation value with the changed threshold;
- and
- controlling the transmission power based on a comparison result.
A power control method in a communication system which comprises a base station and a mobile terminal, comprising:
- in the base station:
- transmitting a first signal including a control signal used for controlling transmission power of the mobile terminal;
- and
- in the mobile terminal:
- receiving the first signal from the base station;
- changing, according to a reception environment, a threshold used for comparing with a correlation value that is obtained from the control signal included in the first signal and a first unique signal;
- comparing the correlation value with the changed threshold;
- and
- controlling the transmission power based on a comparison result.
