, can also be ripe for those skilled in the art using the method for other acquisition CQI values, this part in practice The content known, so details are not described herein.

After serving cell CQI and assistant service cell CQI is got in a step 101, step is next carried out 102：Meet triggering report condition at least one CQI of serving cell CQI and assistant service cell CQI of the serving cell When, user equipment reports serving cell CQI and/or assistant service cell CQI to base station, to reduce uplink control channel expense. Wherein, base station is specially serving BS and/or secondary serving base station.It should be noted that the reduction uplink control channel is opened Pin is for the single fixed cycle of the prior art reports the technical solution of CQI.

In specific implementation process, step 102 has a variety of different embodiments, will illustrate below to different implementation Form is described in detail.

First embodiment, step 102 are specially：When reaching the first report cycle, user equipment judges serving cell CQI It is greater than or equal to the difference of the CQI once reported before CQI of at least one CQI in assistant service cell CQI and this Threshold value, then report the CQI groups where a CQI according to the first report cycle；Or

If reach the first report cycle, user equipment judges own in serving cell CQI and assistant service cell CQI The difference of CQI and each preceding CQI once reported are respectively less than threshold value, then do not report serving cell CQI and assistant service cell CQI。

Under Inter-NodeB SF-DC transmission modes, step 102 is specially：When reaching the first report cycle, Yong Hushe The standby difference for judging the preceding CQI once reported of at least one a CQI and CQI in CQI1 and CQI2 is greater than or equal to door Limit value, then report the CQI groups where a CQI according to the first report cycle；If reach the first report cycle, user equipment Judge that the difference of all CQI and each preceding CQI once reported in CQI1 and CQI2 are respectively less than threshold value, then do not report service small Area CQI and assistant service cell CQI.

Specifically, under Inter-NodeB SF-DC transmission modes, the CQI that is obtained in step 101 for CQI1 and CQI2, then in a step 102, it is assumed that the first report cycle is 2 milliseconds（ms）, when reaching the first report cycle, user equipment Judge whether CQI1 and the difference of the preceding CQI1 once reported are more than or equal to threshold value, for example, the CQI1 that step 101 obtains is 7, The preceding CQI1 once reported is 9, then difference 2, it is assumed that threshold value 1, then the result of judgement is exactly that the difference is greater than Threshold value, be the result of an affirmative；Similar, user equipment also judges that the difference of CQI2 and the preceding CQI2 once reported are It is no to be greater than or equal to threshold value.

In practice, in order to economize on resources and the time, any one in CQI1 and CQI2 can be first judged, if The result is that certainly, such as foregoing CQI1 and the preceding difference once reported are 2, more than threshold value 1, then can no longer judge CQI2, then directly reports CQI1 and CQI2 according to the report cycle of 2ms.If for CQI1 or CQI2 judging result whether Fixed, then another is next judged again, such as first judges CQI1, if the result is that negating, then be just further continued for judging CQI2, if the judging result to CQI2 is affirmative, then CQI1 and CQI2 just are reported according to the report cycle of 2ms, and such as The judging result of fruit CQI2 is also that negative, i.e. CQI1 and CQI2 are respectively less than threshold value with each preceding CQI value once reported, that CQI1 and CQI2 are not just reported, i.e., does not report CQI1 and CQI2.Then repeat and perform step 101 and step 102.

Certainly, in another embodiment, user equipment can also judge CQI1 and CQI2 at the same time.

Under Inter-NodeB DF-3C transmission modes, step 102 is specially：When reaching the first report cycle, Yong Hushe The standby difference for judging the preceding CQI once reported of at least one a CQI and CQI in CQI1 and CQI3, CQI2 be more than or Equal to threshold value, then the CQI groups where a CQI are reported according to the first report cycle；If reach the first report cycle, use Family equipment judges that the difference of all CQI and each preceding CQI once reported in CQI1 and CQI3, CQI2 are respectively less than threshold value, then Serving cell CQI and assistant service cell CQI are not reported.

Specifically, under Inter-NodeB DF-3C transmission modes, serving cell CQI includes CQI1 and CQI3, auxiliary Serving cell CQI is CQI2, then in this mode, user equipment using determination methods similar to the above judge CQI1 and Whether there are at least one CQI and the difference of the preceding CQI once reported to be greater than or equal to threshold value in CQI3, CQI2, it is assumed that to judge Result represent there is one to meet Rule of judgment in CQI1 and CQI3, CQI2, if meet Rule of judgment be CQI1 and/or CQI3, then the CQI groups of CQI1 and CQI3 are just reported, without reporting CQI2；If that meet Rule of judgment is CQI2, then just CQI2 is reported, the CQI groups without reporting CQI1 and CQI3；If all CQI（CQI1、CQI2、CQI3）All it is unsatisfactory for judging bar Part, then just do not report all CQI.

Under Inter-NodeB DF-4C transmission modes, step 102 is specially：When reaching the first report cycle, Yong Hushe The difference of the preceding CQI once reported of at least one a CQI and CQI in standby judgement CQI1 and CQI3, CQI2 and CQI4 More than or equal to threshold value, then the CQI groups where a CQI are reported according to the first report cycle；If reaching first reports week During the phase, the difference of all CQI and the respective preceding CQI once reported are equal in user equipment judgement CQI1 and CQI3, CQI2 and CQI4 Less than threshold value, then serving cell CQI and assistant service cell CQI are not reported.

Specifically, under Inter-NodeB DF-4C transmission modes, serving cell CQI includes CQI1 and CQI3, auxiliary Serving cell CQI includes CQI2 and CQI4, then in this mode, user equipment is judged using determination methods similar to the above Whether there are at least one CQI and the difference of the preceding CQI once reported to be greater than or equal to thresholding in CQI1 and CQI3, CQI2 and CQI4 Value, it is assumed that the result of judgement represents have one to meet Rule of judgment in CQI1 and CQI3, CQI2 and CQI4, if meeting to judge bar Part is CQI1 and/or CQI3, then just reports the CQI groups of CQI1 and CQI3, the CQI groups without reporting CQI2 and CQI4；Such as That fruit meets Rule of judgment is CQI2 and/or CQI4, then just report the CQI groups of CQI2 and CQI4, without report CQI1 and The CQI groups of CQI3；If all CQI（CQI1、CQI2、CQI3、CQI4）All it is unsatisfactory for Rule of judgment, then just do not report all CQI。

It can be seen from above description in the present embodiment, only in the difference of the current CQI and preceding CQI once reported During more than or equal to threshold value, i.e., when the diversity ratio of current CQI and the preceding CQI once reported are larger, it can just report CQI, and When difference is little, CQI is not just reported, so the method reported compared to a fixed cycle, can reduce uplink control channel Expense.

Second embodiment of step 102, in the present embodiment, as soon as user equipment often reports time CQI, starts or restarts First timer, during first timer is run, user equipment reports CQI according to the method in foregoing first embodiment. If when first timer is full, the difference of all CQI and each preceding CQI once reported are respectively less than threshold value, then When first timer is full, all CQI are just reported.

With reference to first embodiment, step 102 specifically further includes：Start when reporting CQI groups according to the first report cycle Or restart first timer；When first timer is full, the user equipment to report CQI groups；The wherein initial value of first timer More than the first report cycle.

Continuing first to illustrate by taking Inter-NodeB SF-DC transmission modes as an example, it is assumed that the first report cycle is 2ms, And the initial value of first timer is 10ms.When reaching the first report cycle, user equipment judge the result is that CQI1 and CQI2 In the difference of the preceding CQI once reported of at least one CQI and a CQI be greater than or equal to threshold value, then just with 2ms The CQI groups of CQI1 and CQI2 are reported, and starts or restarts first timer, it is assumed that are the mode of reverse countdown, i.e., from 0ms to 10ms Time increase.

It is that user equipment judges the result is that negative, i.e., all CQI and each preceding CQI once reported assuming that in 2ms Difference be respectively less than threshold value, then just do not report the CQI groups of CQI1 and CQI2；Then in 4ms, the knot of user equipment judgement Fruit is affirmative, then the CQI groups of CQI1 and CQI2 will be reported, will be given the correct time upper, first timer is restarted again, and from 0ms Start timing, repeat the above process until certain once whole first timer run during, user equipment is to all CQI's Judging result is all negative, i.e., during whole first timer is run, user equipment does not all report CQI1's and CQI2 CQI groups, then when first timer is full, just report the CQI groups of all CQI1 and CQI2, and restart first timer, repeat The above process.Wherein, the initial value of first timer is more than the first report cycle.

For Inter-NodeB DF-3C transmission modes and Inter-NodeB DF-4C transmission modes, situation and Inter- NodeB SF-DC transmission modes are similar, and a first timer can be configured by simply corresponding to each CQI groups, i.e., to each CQI groups A CQI is often reported, can all start or restart first timer corresponding with the CQI groups, in the whole first timer runtime Between, user equipment reports the CQI groups according to first embodiment, and after the corresponding first timer is full, user equipment to report should CQI groups, and restart the corresponding first timer, repeat the above process.

Specifically, such as by taking Inter-NodeB SF-DC transmission modes as an example, it is assumed that the first report cycle is 2ms, is reached It is that user equipment judges the result is that the difference of CQI1 and the preceding CQI1 once reported are more than threshold value during to the first report cycle, The result that CQI4 judges is also affirmative, then just reports the CQI groups of CQI1 and CQI3, and starts or restart CQI1's and CQI3 The corresponding first timer of CQI groups；Also the CQI groups of CQI2 and CQI4 are reported, and start or restart the CQI groups pair of CQI2 and CQI4 The first timer answered.

Assuming that in 2ms, it is that user equipment judges the result is that the difference of the CQI1 and preceding CQI1 once reported is more than door Limit value, and the difference of the CQI4 and preceding CQI4 once reported is less than threshold value, then just report, the CQI groups of CQI1 and CQI3, and Restart the corresponding first timer of CQI groups of CQI1 and CQI3, the CQI groups without reporting CQI2 and CQI4, then CQI2 and The corresponding first timer of CQI groups of CQI4 is just also in the operation phase.If in the CQI groups of CQI2 and CQI4 corresponding When one timer runs to 4ms, user equipment judges whether wherein there is a CQI and this in CQI2 and CQI4 again The difference of the CQI once reported before CQI is greater than or equal to threshold value, if the result is that certainly, such as CQI2 meet judge bar Part, then, the CQI groups of CQI2 and CQI4 are just reported, and the corresponding first timer of CQI groups of CQI2 and CQI4 is restarted, The timing since 0ms again, repeats the above process until certain is once in the corresponding first timer of CQI groups of whole CQI2 and CQI4 During operation, user equipment is all negative to the judging result of all CQI, i.e., during whole first timer is run, User equipment does not all report the CQI groups of CQI2 and CQI4, then expires in the corresponding first timer of CQI groups of CQI2 and CQI4 When, the CQI groups of CQI2 and CQI4 are just reported, and restart the corresponding first timer of CQI groups of CQI2 and CQI4, repeat above-mentioned mistake Journey.Wherein, the initial value of first timer is more than the first report cycle.

And when the corresponding first timer of CQI groups of CQI2 and CQI4 runs to 4ms, the CQI groups of CQI1 and CQI3 At this moment corresponding first timer has run to 2ms, then user equipment is judged in CQI1 and CQI3 again because being restarted The difference for whether wherein having the CQI once reported before an a CQI and CQI is greater than or equal to threshold value, if the result is that Certainly, such as CQI1 meets Rule of judgment, then, just report the CQI groups of CQI1 and CQI3, and the CQI groups of CQI1 and CQI3 Corresponding first timer is restarted again, and the timing since 0ms, repeat the above process until certain once in whole CQI1 and During the corresponding first timer operation of CQI groups of CQI3, user equipment is all negative to the judging result of all CQI, I.e. during whole first timer is run, user equipment does not all report the CQI groups of CQI1 and CQI3, then in CQI1 and When the corresponding first timer of CQI groups of CQI3 is full, the CQI groups of CQI1 and CQI3 are just reported, and restart the CQI of CQI1 and CQI3 The corresponding first timer of group, repeats the above process.

Through this embodiment, descending scheduling can be influenced to avoid CQI is not reported for a long time.

3rd embodiment, in the present embodiment, step 102 specifically includes：When user equipment is received under the transmission of base station When row data or CQI activation instructions, start or restart second timer；

During second timer is run, user equipment reports CQI according to the first report cycle；

After second timer is full,

When reaching the first report cycle, user equipment is judged at least one in serving cell CQI and assistant service cell CQI The difference of the preceding CQI once reported of an a CQI and CQI is greater than or equal to threshold value, then according on the first report cycle Report the CQI groups where a CQI；Or

If reach the first report cycle, user equipment judges own in serving cell CQI and assistant service cell CQI The difference of CQI and each preceding CQI once reported are respectively less than threshold value, then do not report serving cell CQI and assistant service cell CQI；

Wherein, the initial value of second timer is more than the first report cycle.

I.e. in the present embodiment, no matter user equipment is to receive downlink data from serving cell or assistant service cell Wrap or be receive base station transmission CQI activation instructions when, can all start or restart second timer；In second timer During operation, just all CQI are reported according to the first report cycle；And after second timer is full, just according to first embodiment In method reported.Because receive downlink data or CQI activation instructions, then it represents that at this moment need frequently to report CQI, And after second timer is full, before downlink data or CQI activation instructions is not received by, mean that at this moment to the need of CQI It is not very high to ask, so preferably, the initial value of second timer is more than the value of the first report cycle, such as the first report cycle For 2ms, and the initial value of second timer is 8ms.

Further, after second timer is full, CQI is reported in the method in first embodiment so that CQI is reported more Correspond to actual needs, and then further reduce the expense of uplink control channel.

Equally, the method in the present embodiment is suitable for foregoing three kinds of transmission modes.

4th embodiment, in the present embodiment, step 102 is specially：User equipment receives the clothes in multiple stream transmission When any cell is sent in cell of being engaged in and assistant service cell CQI activation instructions or downlink data, with the first report cycle Report serving cell CQI and assistant service cell CQI.Wherein, CQI activation instructions can be, but not limited to believe by high speed Compliance control Road instructs（HS-SCCH order）To carry.For example when receiving the activation instruction or downlink data of serving cell, then report immediately CQI, then periodically reports CQI with the first report cycle.

Such as under Inter-NodeB SF-DC transmission modes, user equipment receives any small in cell 1 or cell 2 The CQI activation instructions or downlink data that area is sent, just report CQI1 and CQI2 with the period 1.Period 1 is, for example, 2ms.
