摘要： A channel interleaver comprises a novel constellation-based permutation module. The channel interleaver first receives a plurality of sets of encoded bits generated from an FEC encoder. The encoded bits are distributed into multiple subblocks and each subblock comprises a plurality of adjacent bits. A subblock interleaver interleaves each subblock and outputs a plurality of interleaved bits. The constellation-based permutation module rearranges the interleaved bits and outputs a plurality of rearranged bits. The rearranged bits are supplied to a symbol mapper such that a plurality of consecutively encoded bits in the same set of the encoded bits generated from the FEC encoder is prevented to be mapped onto the same level of bit reliability of a modulation symbol. In addition, the plurality of adjacent bits of each subblock is also prevented to be mapped onto the same level of bit reliability to achieve constellation diversity and to improve decoding performance.

摘要： A communications apparatus is provided. A controller determines two different sub-frame subsets for configuring a peer communications apparatus to perform channel state information measurement according to time-domain variation of a level of interference of the peer communications apparatus obtained from one or more previous measurement result(s). A transceiver transmits a configuration message carrying information regarding the two sub-frame subsets to the peer communications apparatus and receives one or more measurement result reporting message(s) carrying information regarding the measurement result(s) from the peer communications apparatus.

摘要： A communications apparatus is provided. A controller module generates a suggested sub-frame pattern describing suggested arrangement of one or more almost blank sub-frame(s) in one or more frame(s) and schedules control signal and/or data transmissions according to the suggested sub-frame pattern. A transceiver module transmits at least a first signal carrying information regarding the suggested sub-frame pattern to a peer communications apparatus. The peer communications apparatus does not schedule data transmissions in the almost blank sub-frame(s).
