US 7,120,457 B2 · Transmission control method and apparatus for mobile communication system

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.

Dependent claims

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.
