摘要: A method and apparatus for selecting an error correction code rate in a cellular radio system. Each base station broadcasts power product value, PP, which is its transmit power, PBT, multiplied by desired receive PBR. mobile unit determines appropriate PMT, measuring received PMR, calculating PP/PMR (24). If, due to large channel loss, the calculation result exceeds maximum capability of (25), uses lower adjusts accordingly (27, 31). Three rates, 2/3, 1/2, 1/3, are used preferred embodiment dependence on amount loss. The selection can also depend quantity data be transmitted (30, 33, 34). detect attempting decode all rates choosing best result.
