Description
Technical Field
The present invention relates to the field of communications, and in particular, to an information modulation method and apparatus.
Background
In the face of the requirements of the next generation of wireless access continuous wide area coverage and hot spot high capacity scenes, the existing orthogonal multiple access technology cannot be well supported, the technology of multi-code stream superposition transmission theoretically has a higher capacity boundary, and especially when a far-end user of a cell approaches the capacity limit of a single user, the far-end user can obtain the higher capacity of a near-end user.
In an orthogonal multiple access system, a base station performs coded Modulation on bit Information according to a Modulation and Coding Scheme (MCS) in Downlink Control Information (DCI), and informs User Equipment (UE) of DCI transmission. Wherein, after the bit information of the single codeword stream can be modulated according to Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (16 QAM), 64QAM, 256QAM Modulation schemes,
in non-orthogonal multiple access system, multiple code word streams are encoded in superposition, taking two code word streams as example, let one end user and one near end user pair, two code word streamsAfter being respectively coded and modulated, the signals are weighted by the transmission power ratio and then are superposed to obtain a synthesized transmission symbol. The transmission power ratio is the power ratio of the modulation symbols of the near-end user, i.e. PNear to/(PNear to+PFar away)。
For example, the far-end QPSK modulation symbol and the near-end 16QAM modulation symbol are superimposed, and the transmission power ratio is α, the resultant constellation is a 64-point constellation, as shown in fig. 1a to 1 c. Observing the composite constellation as can be easily seen in fig. 1c, the 4 constellation groups are scattered in 4 quadrants, the smaller the α, the more scattered.
However, the existing LTE system is independently code-modulated for each codeword stream, and cannot support superposition transmission of two codeword streams. In addition, with respect to the orthogonal multiple access system, the data symbol mapped to the time-frequency resource is not BPSK, QPSK, 16QAM, 64QAM, 256QAM modulation symbol of a single user, but is an uncertain gray composite constellation symbol generated by superposition coding of multiple codeword streams. In summary, a modulation method for multi-codeword stream superposition transmission applicable to and supporting non-orthogonal systems is lacking.
Aiming at the problem that the multi-code stream superposition transmission of a non-orthogonal system cannot be supported in the related technology, an effective solution is not provided yet.
