Information generates submodule 122, is used for according to the difference of the CQI value of the CQI value of judging the main carrier that submodule 121 is judged and less important carrier wave and the magnitude relationship of predetermined threshold value, the less important carrier channel quality information of generation.

Information sending module 13, for explicit information reporting policy or the implicit information reporting policy of the notification message that receives according to first receiver module 11, send the less important carrier channel quality information that information generating module 12 generates by main carrier or less important carrier wave.

Wherein, terminal 1 also comprises second receiver module 14, is used for reporting by the termination that main carrier or less important carrier wave reception base station 2 send the notification message of less important carrier channel quality information, so that information sending module 13 stops to send less important carrier channel quality information.

Further, first sending module 11 also is used for receiving the startup Indication message that base station 2 sends by main carrier, and beginning receives/send data at less important carrier wave;

Second sending module 14 also is used for receiving the termination Indication message that base station 2 sends by main carrier or less important carrier wave, terminates on the less important carrier wave and receives data.

Base station 2, be used for sending the notification message that reports less important carrier channel quality information by main carrier or less important carrier wave to terminal 1, the less important carrier channel quality information that receiving terminal 1 sends by main carrier or less important carrier wave, according to the less important carrier channel quality information that receives, determine less important carrier wave to receive/send the scheduling mode of data, and send the notification message that stops reporting less important carrier channel quality information by main carrier or less important carrier wave to terminal 1, specifically comprise:

First sending module 21 is used for sending the notification message that reports less important carrier channel quality information by main carrier or less important carrier wave to terminal 1, and indicating terminal 1 sends less important carrier channel quality information by main carrier or less important carrier wave;

Wherein, base station 2 also comprises second sending module 24, is used for sending the notification message that stops reporting less important carrier channel quality information by main carrier or less important carrier wave to terminal 1, and indicating terminal 1 only sends less important carrier channel quality information eventually.

Further, first sending module 21 also is used for sending the startup Indication message by main carrier to terminal, and indicating terminal 1 beginning receives/send data at less important carrier wave;

Second sending module 24 also is used for sending the termination Indication message by main carrier or less important carrier wave to terminal, and indicating terminal 1 terminates on the less important carrier wave and receives data.

Above-mentioned module can be distributed in a device, also can be distributed in a plurality of devices.Above-mentioned module can be merged into a module, also can further split into a plurality of submodules.

The technical scheme of the embodiment of the invention has the following advantages, because the device that has adopted terminal to carry out the CQI report by main carrier, avoided sending the resource consumption that cycle CQI report causes, and by only receiving/sending the mode that data phase is kept the CQI channel of less important carrier wave, reached when keeping message scheduling, saved the effect of channel resource.

In multicarrier system, whether base station (Base Station) goes indicating terminal to receive data or close reception (closing receiver or receiving function) at less important carrier wave (Secondary carrier) by main carrier (Primary carrier), in order further to improve the efficient of eating dishes without rice or wine, terminal only receives time period ability transmitting channel quality information (such as CQI) on this carrier wave or main carrier of data at less important carrier wave, at other times, in the receiver of closing certain less important carrier wave in terminal (perhaps receiving function), terminal does not send the channel quality information of this carrier wave, thereby saved the expense that the reporting channel quality information of terminal on less important carrier wave brings, based on such technological thought, the embodiment of the invention three has proposed a kind of message scheduling method, as shown in Figure 3, may further comprise the steps:

Step S301, base station go indicating terminal to receive data at less important carrier wave by main carrier.

Step S302, base station send the notification message of feedback CQI report to this terminal by main carrier.

This information can comprise following one or multinomial:

1, indicate the carrier information which less important carrier wave the CQI that reports is, carrier information can be the index of carrier wave, the center frequency point of carrier wave, bandwidth of carrier wave etc.;

2, the CQI content and the form that need feedback, such as whether comprising broadband CQI, subband CQI etc., still direct modulating-coding is indicated (MCS Indication).

3, the resource assignment information that is used for feedback CQI report, the carrier information, beginning frame number information (Start Frame Number), the cycle information (periodic that comprise the ascending resource place, indicate and how long feed back CQI one time), effectively indication information (information indicates the CQI report cycle, and whether only to receive the data time section at less important carrier wave effective, still the All Time section is effective), Resource Block information (Resource Block information), resource assignment information can comprise above-mentioned one or more.

Need further be pointed out that; there is not inevitable precedence relationship between step S301 and the step S302; the notification message of feedback CQI report can send before less important carrier wave receives data at indicating terminal; also can send simultaneously in the message that less important carrier wave receives data with indicating terminal; can also be in terminal after less important carrier wave receives data; send the notification message of feedback CQI report again to terminal, such variation all belongs to protection scope of the present invention.

Step S302, after terminal is received this notification message, receive data by the less important carrier wave in above-mentioned message appointment.

If oneself is through indicating the notification message that is used for feedback CQI report of this less important carrier wave among the step S301, terminal is according to this notification message feedback CQI information so;

If do not indicate the notification message that is used for feedback CQI report of this less important carrier wave among the step S301, the base station can begin to send this notification message in the time period of less important carrier wave reception data to it in terminal so.Terminal is again according to this notification message feedback CQI information.

It is to close at less important carrier wave to receive data (closing receiver or receiving function) that indicating terminal is removed by main carrier or less important carrier wave in step S303, base station.

Step S304, base station send the notification message that stops to feed back the CQI report to terminal.

Wherein, this notification message comprises following one or multinomial:

1, indicate the carrier information of less important carrier wave, carrier information can be the index of carrier wave, the center frequency point of carrier wave, bandwidth of carrier wave etc.;

2, stop to send the indication of CQI information, or this information acquiescence and close reception information related (or the effect of this indication is born by closing reception information);

3, indicate the temporal information that begins to stop to send CQI information, such as stopping to feed back CQI information behind how many frames of explanation, perhaps directly indicate the frame number information (Frame Number) that stops to send CQI information, perhaps receiving behind the indication information that stops to send CQI information acquiescence closes in next subframe and receives data (perhaps other time point, such as next superframe etc.).

Need further be pointed out that; there is not inevitable precedence relationship between step S303 and the step S304; the notification message that stops to feed back the CQI report can be closed at less important carrier wave at indicating terminal and be sent before receiving data; also can close the message that receives data at less important carrier wave with indicating terminal sends simultaneously; can also close the operation that receives data from less important carrier wave with terminal binds mutually; namely as long as terminal is closed the reception data from less important carrier wave; then stop to feed back the CQI report, such variation all belongs to protection scope of the present invention.

Step S305, after terminal is received this notification message, will close the receiver of the less important carrier wave of above-mentioned message appointment, and stop to send the CQI information of this less important carrier wave.

The technical scheme that proposes of the embodiment of the invention as the aforementioned, the embodiment of the invention need not arrange the CQI report (periodic CQI report) in cycle at the non-reception/transmission data phase of less important carrier wave (Secondary carrier), terminal be can save so in a large number and channel quality indicating channel (Channel Quality Indicator Channel, expense CQICH) kept at less important carrier wave.

Simultaneously, in order to make the base station can carry out data dispatch (wherein, the scope of M value is 1～receives/send the frame number of data) according to appropriate C QI at the M frame (first M frame) of the beginning of the reception/transmission data phase of the less important carrier wave of terminal.The base station indicating terminal is before reception/the transmission data phase begins of less important carrier wave, to report once or the repeatedly CQI report of less important carrier wave by main carrier or less important carrier wave, therefore, the suitable data scheduling can be carried out at the M frame of the beginning of the reception/transmission data phase of less important carrier wave according to this CQI report in the base station.

Based on above-mentioned technological thought, as shown in Figure 4, the embodiment of the invention four has proposed a kind of message scheduling method, may further comprise the steps:

Step S401, base station send the notification message of the CQI report that reports less important carrier wave to terminal.

The base station sends a notification message before reception/the transmission data phase begins of the less important carrier wave of terminal, and the notice terminal will report the CQI report of less important carrier wave.

This notification message can adopt broadcast (as beep-page message etc.) to realize, also can adopt unicast messages (such as pointing out that terminal carries corresponding CQI announcement information simultaneously when reporting the information of the reception of less important carrier wave/transmission data phase), perhaps multicast message is realized.

Wherein, this notification message comprises one or more of following content:

(1) indicates the carrier information which less important carrier wave the CQI that reports is.Carrier information can be the index of carrier wave, the center frequency point of carrier wave, the bandwidth of carrier wave etc.

(2) CQI content and the form that need feed back.Such as whether comprising broadband CQI (wideband CQI), subband CQI (Subband CQI) etc.

(3) be used for the resource assignment information that feedback CQI reports, comprise carrier information, frame number information (Frame Number), the Resource Block information (Resource Block information) at ascending resource place.

The CQI report of the less important carrier wave that step S402, base station receiving terminal report.

After terminal was received this notification message, the ascending resource of the carrier wave by the notification message appointment in above-mentioned steps S301 reported the CQI report of the less important carrier wave of appointment.

Step S403, base station determine less important carrier wave to begin to receive/send the data dispatch mode of the initial frame of data according to the CQI report that receives.

Being the base station decides the data dispatch mode of beginning M frame (first M frame) of the reception/transmission data phase of this less important carrier wave according to CQI report received among the above-mentioned step S302, such as modulation coding mode (MCS) etc.

The technical scheme of the embodiment of the invention has the following advantages, carry out CQI method of reporting at less important carrier wave before reception/the transmission data phase begins because adopted the notice terminal, avoided sending the resource consumption that cycle CQI report causes, and by only receiving/sending the mode that data phase is kept the CQI channel of less important carrier wave, reached when keeping message scheduling, saved the effect of channel resource.

The embodiment of the invention has also proposed a kind of message scheduling method, and the technological thought of this method is described below:

When the main carrier of terminal and less important carrier wave are adjacent carrier, terminal does not arrange cycle CQI report at the non-reception/transmission data phase of less important carrier wave, thereby has saved terminal is kept the CQI channel at less important carrier wave expense in a large number.

Because the main carrier cause adjacent with less important carrier wave, the CQI of main carrier and less important carrier wave should be close, and therefore, the error amount of this CQI is acceptable in actual applications.

Simultaneously, in order to make that the base station can be at the reception/transmission data phase of the less important carrier wave of terminal, use suitable MCS to carry out data dispatch to its initial frame, the technical scheme that the embodiment of the invention proposes is to adopt the CQI of main carrier as deciding MCS mechanism with reference to value.

Namely, when the initial frame that less important carrier wave is begun to receive/send data carries out message scheduling, the data foundation that adopts is the CQI of main carrier, and other frames after less important carrier wave being begun receive/send the initial frame of data are when carrying out message scheduling, and the foundation of employing can be that the CQI information of main carrier also can be the cycle CQI information of less important carrier wave.

Based on above-mentioned technological thought, the embodiment of the invention five has proposed a kind of message scheduling method, and as shown in Figure 5, this method may further comprise the steps:

Whether the CQI difference of step S501, terminal judges main carrier and less important carrier wave is greater than predetermined threshold value.

When the CQI of terminal judges main carrier and less important carrier wave difference is less than or equal to predetermined threshold value, when namely the CQI of the main carrier measured of terminal and less important carrier wave is more or less the same, execution in step S402;

When the CQI of terminal judges main carrier and less important carrier wave difference during greater than predetermined threshold value, when namely the CQI of the main carrier measured of terminal and less important carrier wave differs big, execution in step S403.

Step S502, terminal directly send the CQI of main carrier to the base station.

The CQI of less important carrier wave will directly be assessed in the base station according to the CQI of main carrier.

In this step, terminal does not need to report any less important carrier wave CQI information.

After this step is finished, execution in step S404.

Step S503, terminal will initiatively report the difference of main carrier CQI and less important carrier wave CQI with form of message on main carrier.

The base station will report that the difference that reports in the message therewith assesses the CQI of less important carrier wave in conjunction with the CQI of main carrier.

After this step is finished, execution in step S404.

Step S504, base station decide at less important carrier wave according to above-mentioned less important carrier wave CQI and begin to receive/send the MCS mechanism that the initial frame of data phase uses.

Further, according to above-mentioned method flow, the situation that the embodiment of the invention differs bigger to the CQI of above-mentioned main carrier and less important carrier wave is specifically described as follows, and as shown in Figure 6, this scheme may further comprise the steps:

Step S601, terminal report the CQI report of main carrier to the base station on main carrier.

Step S602, terminal report the difference of main carrier CQI and less important carrier wave CQI to the base station on main carrier.

Step S603, base station assess the CQI of less important carrier wave according to the difference of the CQI of main carrier and main carrier CQI and less important carrier wave CQI.

Step S604, according to the CQI of less important carrier wave of assessment, be this terminal scheduling resource at the initial frame of the reception/transmission data phase of less important carrier wave.

The technical scheme of the embodiment of the invention has the following advantages, under the main carrier situation adjacent with less important carrier wave, because adopted the CQI that assesses less important carrier wave according to the CQI of main carrier, and according to the assessment result of the CQI of less important carrier wave, less important carrier wave is received/sends the method that the initial frame of data phase carries out message scheduling, avoided sending the resource consumption that cycle CQI report causes, reached when keeping message scheduling, saved the effect of channel resource.

The embodiment of the invention six has also proposed a kind of message scheduling method, and is specific as follows to the technical scheme of this method:

No matter less important carrier wave is that to be in reception/transmission data phase also be non-reception/transmission data phase, terminal remains on the cycle CQI report of this less important carrier wave, that is to say the non-reception/transmission data phase at less important carrier wave, terminal can be opened radio circuit less important carrier wave is carried out the CQI measurement, reports the cycle CQI report of less important carrier wave then by main carrier.

The base station receives that according to the last time the cycle CQI report of the less important carrier wave that terminal sends decides the data dispatch mode of the initial frame of the reception/transmission data phase at this less important carrier wave, such as modulation coding mode (MCS) etc.

Whether terminal can be according to local policy, thereby sufficient or be connected on the power supply that can not decay and needn't consider power saving effect etc. such as electric quantity of power supply, adopts this kind CQICH mode with base station negotiate.

The technical scheme of the embodiment of the invention has the following advantages, because report the cycle CQI method of reporting of less important carrier wave by main carrier, in the resource consumption that the CQI channel of avoiding keeping less important carrier wave causes, realized obtaining the cycle CQI of less important carrier wave report, reached when keeping message scheduling, saved the effect of channel resource.
