摘要： Methods and apparatus for balancing multi-symbol modulation schemes in cellular communications are provided. The modulation schemes include a plurality of modulation symbols, each of which codes a predefined bit group, which includes one or more bits. The bit groups define different bit positions for bits within the bit groups. The bit positions of the modulation symbols are associated with different error probability levels. Each error probability level defines a probability level of an erroneous bit value at a defined bit position in the bit group, which is obtained by a mapping operation from the modulation symbol transmitted over a radio frequency channel with noise. Binary content to be modulated is provided in form of code blocks I (where i=1 to n). Each of the code blocks is carried on a corresponding code channel i. The code blocks on the code channels are supplied to the modulation schemes in that each code channel is associated with one predefined bit position of the bit groups to enable a mapping to modulation symbols. The bit groups are formed from the binary content of the code blocks in accordance with the code channel-to-bit position association defined above. The binary content of at least two code blocks is shuffled, distributed, or scattered in accordance with predetermined shuffling, distributing, or scattering rules. The shuffling, distributing, or scattering aims to achieve substantially balanced or same error probability levels for said code channels. The shuffling operation should be performed to achieve a substantially evenly distribution of the binary content upon the involved code blocks.
