摘要： The present invention provides a constellation mapping method, and the method includes: flipping a plurality of bits in each modulation symbol unit to be mapped in part of or all of modulation symbol units to be mapped of a bit sequence to be mapped; and mapping each flipped modulation symbol unit to be mapped as a modulation symbol in a constellation. By means of the present invention, the phenomenon that consecutive bits have the same reliability can be effectively avoided by changing unevenness of reliability distribution of the consecutive bits, and at the same time, the link performance can be improved.

摘要： The present invention discloses a rate matching method and device. The method includes that: an information bit sequence is coded and interleaved to obtain a mother code codeword with a length NFB—Buffer; and bits are selected from the mother code codeword to generate a hybrid automatic repeat request (HARQ) subpacket for current transmission. By means of the present invention, the effect of covering the whole mother code area can be achieved as much as possible, and the performance of the HARQ multiple retransmission link can be enhanced.

摘要： Disclosed are a method for transmitting feedback of channel state information and user equipment. The method comprises: under a transmission mode, user equipment (UE) determining contents carried by channel state information according to indication information, wherein the indication information comprises at least one of the following: rank indicator (RI), channel quality indication information (CQI) and configuration signaling sent by a base station eNodeB; and the UE sending the channel state information to the eNodeB. The present invention solves the problem that the contents provided by the channel state information are not suitable for those transmission modes under which a multiple user-MIMO and a single user-MIMO can be switched from one to another, improving the applicability of the channel state information.
