Abstract

A method and apparatus for controlling the power of a signal transmitted between a base station and a mobile terminal which constitute a mobile communication system. At least one of the base station and the mobile terminal has functions to compare a predetermined reference value and a necessary transmission power obtained as a result of transmission power control in order to compensate for a signal intensity fluctuation occurring on a link between the base station and the mobile terminal, temporarily stopping the transmission if the necessary transmission power is larger than a predetermined permissible value, and transmit the signal if the necessary transmission power is equal to or smaller than the predetermined permissible value.

Claims (16)

1. A base station for communicating with a mobile terminal, comprising:

an antenna for receiving signals from said mobile terminal and transmitting signals to said mobile terminal; and

a digital signal processor (DSP) for judging whether or not to transmit data to said mobile terminal based on a condition of a channel between said mobile terminal and said base station,

wherein, if said DSP judges not to transmit said data, said transmission of the data is temporarily stopped.

2. A base station according to claim 1 , wherein, if said DSP judges not to transmit said data, said transmission of the data is stopped for at least a slot period.

3. A base station according to claim 1 , wherein said condition of a channel includes a signal intensity of a signal received via the channel between said mobile terminal and said base station.

4. A base station according to claim 3 , wherein said signal intensity is a signal intensity of a signal received at said mobile terminal from the base station.

5. A base station according to claim 1 , wherein said condition of the channel is measured at said mobile terminal, and the base station receives, from said mobile terminal, information indicating said condition of the channel.

6. A method of controlling data transmission from a base station to a mobile terminal, comprising the steps of:

monitoring a condition of a channel between said mobile terminal and said base station;

judging whether or not to transmit data based on said monitored condition of said channel; and

if it is judged not to transmit the data, temporarily stopping said transmission of the data.

7. A method of controlling data transmission according to claim 6 , wherein said transmission is stopped for at least a slot period.

8. A method of controlling data transmission according to claim 6 , wherein said condition of a channel includes a signal intensity of a signal received via the channel between said mobile terminal and said base station.

9. A method of controlling data transmission according to claim 8 , wherein said signal intensity is a signal intensity of a signal received at said mobile terminal from the base station.

10. A method of controlling data transmission according to claim 6 , wherein said condition of the channel is measured at said mobile terminal, and the base station receives, from said mobile terminal, information indicating said condition of the channel.
