Method for the communication of information and apparatus employing the method
First Claim
1. A method of transferring information in units over a wireless digital communications link between a transmitting station and a receiving station comprising the steps of:
- transmitting first information units at a first energy level;
monitoring if correct reception of the transmitted units occurred; and
transmitting second information units associated with the first information units, for which first information units the monitoring did not indicate correct reception occurred, at second energy levels, the second information units allowing the content of the first information units to be established, wherein at least one of the associated second information units is transmitted at an energy level which is selected at least partly so as to minimise the total transmitted energy when averaged over a series of first information unit transmissions with respective second information unit transmissions.

Abstract
A method of transferring information in units over a wireless digital communications link between a transmitting station and a receiving station comprising the steps of: transmitting first information units at a first energy level; monitoring if correct reception of the transmitted units occurred; and transmitting second information units associated with the first information units, for which first information units the monitoring did not indicate correct reception occurred, at second energy levels, the second information units allowing the content of the first information units to be established, wherein at least one of the associated second information units is transmitted at an energy level which is selected at least partly so as to minimise the total transmitted energy when averaged over a series of first information unit transmissions with respective second information unit transmissions. At least one of the second information units may be transmitted with an energy level below the energy level used in transmission of the first information units. Second information units may be transmitted with a redundancy content which is selected to at least partly minimize the total redundant data content when averaged over a series of first information unit transmissions with respective second information unit transmissions.
