Step S206, according to numbering ServCellIndex, backward compatibility carrier wave and newly-increased carrier type non-post to simultaneous
Hold between carrier wave, the CSI of selection carrier wave is fed back.
Divide three kinds of processing modes that this method is described in detail below.
The first processing mode, provides that the ServCellIndex of backward compatibility carrier wave priority is overall high by agreement
In the ServCellIndex (values with the ServCellIndex of two class carrier waves of the non-backward compatible carrier waves of newly-increased carrier type
It is unrelated), then the value again by respective ServCellIndex in the above-mentioned a certain carrier type of selection determines carrier wave
Priority level, such as according to carrier wave ServCellIndex values from small to large, priority is reduced successively, and most priority is most at last
The CSI feedback of high carrier wave is to base station.
Second of processing mode, provides that the ServCellIndex of backward compatibility carrier wave priority is integrally low by agreement
In the non-backward compatible carrier waves of new wave-carring type ServCellIndex (with the ServCellIndex of two class carrier waves value without
Close), then the value again by respective ServCellIndex in the above-mentioned a certain carrier type of selection determines the excellent of carrier wave
First rank, such as according to carrier wave ServCellIndex values from small to large, priority is reduced successively, most highest priority at last
Carrier wave CSI feedback to base station.
The third processing mode, the ServCellIndex and new wave-carring type of backward compatibility carrier wave are provided by agreement
The ServCellIndex of non-backward compatible carrier waves have identical grade (with the ServCellIndex of two class carrier waves value without
Close).The priority level of carrier wave is determined by the respective ServCellIndex values of above-mentioned two classes carrier wave, as according to carrier wave
From small to large, priority is reduced ServCellIndex values successively, most at last the CSI feedback of the carrier wave of highest priority to base
Stand.
Above-mentioned newly-increased carrier type is to extend carrier wave, or burst carrier wave, or other non-backward compatible carrier waves.
It may be noted that the method for top description can be applicable under tdd mode and fdd mode.

ACK/NACK bits carry out cascade sequence from left to right;If the non-post of the backward compatibility carrier wave and newly-increased carrier type is to simultaneous
Hold pairing, then need the ACK/NACK bits of feedback to be inserted into the backward compatibility carrier wave of pairing the non-backward compatible carrier waves
ACK/NACK bits behind, if the non-backward compatible carrier waves have multiple, then the non-backward compatible carrier waves according to
The order of increased number value (or from big to small) from small to large arranges corresponding ACK/NACK bits from left to right, then will row
The bit arranged, which is inserted into behind the ACK/NACK of the backward compatibility carrier wave, (to be noted, increased numbering described here can be
ServCellIndex).Or will need feeding back ACK/NACK backward compatibility carrier wave according to ServCellIndex values by it is small to
Big order to backward compatibility carrier wave need feed back ACK/NACK bits carry out cascade sequence from left to right, then by non-post to
