Embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The invention provides a kind of channel state information feedback method, Fig. 1 is channel status according to embodiments of the present invention The flow chart of information feedback method, as shown in figure 1, including steps S102 to step S104.

Step S102, user equipment carries out carrier wave in the non-backward compatible carrier waves of backward compatibility carrier wave and newly-increased carrier type In the case of polymerization, using for identifying the numbering ServCellIndex of backward compatibility carrier wave, and increase for identifying new increment of load The numbering of ripple type and the backward compatibility carrier wave matched with newly-increased carrier type.

Step S104, according to numbering ServCellIndex and increased numbering, in backward compatibility carrier wave and non-backward compatible Between carrier wave, the CSI of selection carrier wave is fed back.

It is multiple backward with identical PUCCH Report Types priority after newly-increased carrier type is introduced in correlation technique The periodicity CSI feedback rule of compatible carrier wave can not be applicable.In the embodiment of the present invention, new numbering is added, with numbering ServCeIlIndex determines the priority of CSI feedback jointly, and increased new numbering is used for identifying newly-increased carrier type and therewith (herein, the backward compatibility carrier wave has original ServCellIndex and the new volume to the backward compatibility carrier wave of pairing Number, number for totally 2), therefore, the present invention can realize that multiple backward compatibility with identical PUCCH Report Types priority are carried The periodicity CSI feedback rule of ripple stands good after newly-increased carrier type is introduced, and does not influence the CSI of backward compatibility carrier wave Feedback.

Wherein, step S104 includes：Between backward compatibility carrier wave and non-backward compatible carrier waves, selection numbering The CSI of the minimum carrier wave of ServCellIndex values is fed back.

And then, between backward compatibility carrier wave and non-backward compatible carrier waves, selection numbering ServCellIndex value minimums After the CSI of carrier wave is fed back, the above method also includes：Determine selection carrier wave be configured with the non-post of newly-increased carrier type to Compatible carrier wave, and the non-backward compatible carrier waves and the carrier wave of selection of newly-increased carrier type possess identical ServCellIndex Value；Between the carrier wave of selection, select increased number value minimum or the CSI of maximum carrier wave is fed back.

Preferably, between the carrier wave of selection, the CSI of the minimum or maximum carrier wave of increased numbering is selected to be fed back Including：Compare numbering ServCellIndex priority and the priority of increased numbering；According to comparative result, in selection Between carrier wave, the CSI of the minimum or maximum carrier wave of increased numbering is selected to be fed back.

According to the comparative result of numbering ServCellIndex priority and the priority of increased numbering, carrier wave is selected CSI fed back.It is divided into three kinds of situations below to be introduced.

(1) in the case of numbering ServCellIndex priority of the priority less than increased numbering, in selection Between the non-backward compatible carrier waves of newly-increased carrier type in carrier wave, the carrier wave of increased number value minimum or maximum is selected CSI is fed back.

(2) in the case of numbering ServCellIndex priority of the priority higher than increased numbering, in selection In carrier wave, the CSI of backward compatibility carrier wave minimum selection ServCellIndex is fed back.

(3) in the case of numbering ServCellIndex priority and the priority identical of increased numbering, in selection Carrier wave between, select increased number value minimum or the CSI of maximum carrier wave fed back.

In this preferred embodiment, for numbering ServCellIndex and the different situations of the priority of increased numbering, point The measure for not taking different selection carrier wave CSI to be fed back, so, not only ensures that the CSI for having carrier wave is fed back, Er Qiebao The reasonability of selection is demonstrate,proved.

Furthermore, it is contemplated that the CSI feedback failure of the carrier wave selected according to the minimum or maximum principle of increased numbering There is provided a kind of safeguard measure of CSI feedback in problem, this preferred embodiment, i.e., after feeding back unsuccessful, selection numbering The CSI of the minimum carrier wave of ServCellIndex values is fed back.So still ensure that the CSI of carrier wave is fed back.

It should be noted that user equipment knows the volume that base station is configured by way of broadcasting notice or point-to-point notice Number ServCellIndex and increased numbering.So ensure that user can know numbering.

It may be noted that the method for top description is in time division duplex (Time Division Duplex, referred to as TDD) pattern It can be applicable with FDD (Frequency Division Duplex, referred to as FDD) pattern.

It is clear to describe, increased numbering is represented with numbering AddCellIndex below.Numbering AddCellIndex by High level is randomly assigned, and takes 0 to n integer value.

Above-mentioned newly-increased carrier type is to extend carrier wave, or burst carrier wave, or other non-backward compatible carrier waves.

Newly-increased carrier wave and paired backward compatibility carrier wave share a ServCellIndex value, this ServCellIndex and other backward compatibility carrier waves for being configured without newly-increased carrier wave ServCellIndex are equal.

How UE knows in the multiple descending backward compatibility carrier waves oneself used be configured with newly-increased carrier wave on which carrier wave, this Notified by high level by system message, can also use UE-Specific points by the way of broadcast is notified in cell To a mode notified.

Present invention also offers a kind of channel state information feedback method.When the non-backward compatible carrier waves of new wave-carring type make After ServCellIndex, if occurring identical PUCCH reports between backward compatibility carrier wave and between non-backward compatible carrier waves The periodicity CSI conflicts of type are accused, can be using this method processing.

Fig. 2 is the flowchart 2 of channel state information feedback method according to embodiments of the present invention, as shown in Fig. 2 including Steps S202 to step S206.

Step S202, base station using the newly-increased carrier type of numbering ServCellIndex mark non-backward compatible carrier waves with Backward compatibility carrier wave.

Step S204, user equipment carries out carrier wave in the non-backward compatible carrier waves of backward compatibility carrier wave and newly-increased carrier type In the case of polymerization, using the numbering ServCellIndex for identifying backward compatibility carrier wave, and using for identifying new increment of load The numbering ServCellIndex of the non-backward compatible carrier waves of ripple type.

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.

It may be noted that the method for top description can be applicable under tdd mode and fdd mode.

Present invention also offers the method that a kind of positive acknowledgment/NACK information is fed back, Fig. 3 is according to the present invention The flow chart of the positive acknowledgment of embodiment/NACK information feedback method, as shown in figure 3, including steps S302 extremely Step S306.

Step S302, base station using the newly-increased carrier type of numbering ServCellIndex mark non-backward compatible carrier waves with Backward compatibility carrier wave.

Step S304, user equipment carries out carrier wave in the non-backward compatible carrier waves of backward compatibility carrier wave and newly-increased carrier type In the case of polymerization, using for identifying the numbering ServCellIndex of backward compatibility carrier wave, and increase for identifying new increment of load The non-backward compatible carrier waves of ripple type and the volume with the backward compatibility carrier wave of the non-backward compatible carrier waves pairing of newly-increased carrier type Number.

Step S306, according to numbering ServCellIndex and increased numbering, after use to compatible carrier wave and new increment of load Between the non-backward compatible carrier waves of ripple type, the feedback of ACK/NACK information bits is carried out.

In correlation technique, after newly-increased carrier type is introduced, the HARQ-ACK of multiple backward compatibility carrier waves is with PUCCH Feedback bits concatenation rules can not be applicable when format3 feeds back, and in the embodiment of the present invention, add new numbering, new numbering For identifying newly-increased carrier type and paired backward compatibility carrier wave, newly-increased numbering and numbering ServCellIndex is common With the cascade arrangement order for the ACK/NACK information bits for determining backward compatibility carrier wave and newly-increased carrier type.Therefore, it is of the invention Can realize multiple backward compatibility carrier waves ACK/NACK information bits cascade arrangement rule after newly-increased carrier wave is introduced still So it is applicable, and does not influence the waterfall sequence of the ACK/NACK information bits of backward compatibility carrier wave.

Preferably, according to numbering ServCellIndex and increased numbering, backward compatibility carrier wave and newly-increased carrier-class are used The feedback that the non-backward compatible carrier waves of type carry out ACK/NACK information includes：According to numbering ServCellIndex and described newly-increased Plus numbering, in backward compatibility carrier wave and the simultaneous situation of non-backward compatible carrier waves, backward compatibility intercarrier need feedback ACK/NACK bits according to the ascending order of numbering ServCellIndex values to backward compatibility carrier wave need feed back 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 Compatible carrier wave needs the ACK/NACK bits that feed back according to the increased number value order from small to large of non-backward compatible carrier waves Be ranked up, and by the bit after the sequence of non-backward compatible carrier waves be placed on compatible carrier wave sequence after bit the right.

Wherein, it is inserted into the newly-increased carrier-class of the ACK/NACK information bit modular cascade sequences of original backward compatibility carrier wave feedback The ACK/NACK information bits number of type is related to the number of the newly-increased carrier type of system configuration.

The non-backward compatible carrier waves for being described as newly-increased carrier type below also configure ServCellIndex, that is to say, that after To compatible carrier wave and the non-backward compatible carrier waves it is identified with ServCellIndex.

For above-mentioned two classes carrier wave ACK/NACK feedback by the way of following.

Arrange above-mentioned two classes carrier wave ServCellIndex it is preferential identical.Feeding back ACK/NACK's as needed is backward The ServCellIndex of compatible carrier wave and non-backward compatible carrier waves, will according to the order of ServCellIndex values from small to large The corresponding bit numbers of the ACK/NACK final feedback information of arrangement form from left to right.

Processing module, the feelings for carrying out carrier aggregation in the non-backward compatible carrier waves of backward compatibility carrier wave and newly-increased carrier type Under condition, using for identifying the numbering ServCellIndex of the backward compatibility carrier wave, and increase for identifying the new increment of load The non-backward compatible carrier waves of ripple type and the backward compatibility carrier wave with the non-backward compatible carrier waves pairing of the newly-increased carrier type Numbering；

Feedback module, for according to the numbering ServCellIndex and the increased numbering, being carried using the backward compatibility The non-backward compatible carrier waves of ripple and the newly-increased carrier type carry out the feedback of ACK/NACK information.
