Document Type and Number:
Japanese Patent JP3583388
Kind Code:
B2
Abstract:
Data communication apparatus based on type-2 hybrid ARQ methodwhich can improve the quality of transmission data while avoiding the increase of power consumption. In the present data communication apparatus transmits identical information bit (S) several number of times, and, at this time, controls transmission power of transmission packet for every packet so that the total of transmission power of N times corresponding to N times transmitted identical information bit becomes constant, for example, the transmission power (b) of one packet of information bit at each transmission time becomes 1/N of the transmission power (a) of one packet, that is, (b = a/N).
