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 (7)

1. A mobile terminal which communicates with a base station by radio, comprising:

an antenna for receiving signals from said base station and transmitting signals to said base station; and

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

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

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

3. A mobile terminal according to claim 2 , 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 mobile terminal 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.
