Abstract

The method described relates to sending repeated transmission units from a transmitter to a receiver such that data is transmitted M times in M transmission units. The receiver may use the first i received units 402, where i<M, to attempt to successfully decode the received data. The received units are combined 404 and compared to a threshold range 412, which is a threshold 406 +/- a determined margin 408, and if the result or decision is inside the range the receiver continues to receive the next repeated transmission unit(s) 414. If the result/decision is outside of the range a satisfactory/reliable result is determined and a decision is made 416. Battery saving is made as the receiver may stop reception of further repeated transmission units when the decision is determined to be reliable and the decision is made 416. The range may have a size which approaches zero, linearly or non-linearly, as i increases. The comparison may be based on a power or amplitude of the received signal. Figure 7 shows as example wherein a range between decision threshold t to a decision threshold +t is determined and compared a received signal r with a probability density. The method may, for example, be used in a E-HICH, E-DCH Hybrid ARQ Indicator Channel or E-RGCH, E-DCH Relative Grant Channel.
