Abstract
The invention relates to a method and apparatus for transmitting data from a first node to a second node of a communication system, the method comprising the steps of a first mode of operation, transmitting said data via a first communication channel in which the power level of the channel at said first node is not indicated to the second node, and in a second mode of operation transmitting said data via said first communication channel and indicating the power level of the channel at said first node to said second node.
Claims31
A method of transmitting data from a first node to a second node of a communication system, the method comprising the steps of:
- in a first mode of operation, transmitting said data via a first communication channel in which the power level of the channel at said first node is not indicated to the second node;
- and
- in a second mode of operation transmitting said data via said first communication channel and indicating the power level of the channel at said first node to said second node.
The method as claimed in any preceding claim, further comprising the steps of:
- measuring the quality of said first communication channel and responsive to said measured quality falling below a predetermined threshold value, transmitting said data in said first mode of operation.
The method as claimed in any preceding claim wherein said communication system comprises a telecommunication system.
A method of transmitting data from a first node to a second node of a communication system comprising the steps of:
- measuring channel quality in a first communication channel via which said data is to be transmitted;
- if said measured channel quality falls below a predetermined threshold value, transmitting said data in a first mode of operation in which the power level of the channel at said first node is not indicated to the second node;
- and
- if said measured channel quality is equal to or better than the predetermined threshold value, transmitting said data signal in a second mode of operation in which the power level of the channel at said first node is indicated to said second node.
Power control apparatus for controlling the power level of a first communication channel used for transmitting data from a first node to a second node of a communication system, the power control apparatus comprises:
- measuring means arranged to measure the quality of said first communication channel;
- comparison means arranged to compare a measured channel quality with a predetermined threshold quality and output a mode control signal in response thereto;
- indicating means responsive to said mode control signal for outputting, in a second mode of operation, information which indicates the power level of the first communication channel at said first node to the said second node.
