Bright protection scope.
Shown in referring to Fig.1, wireless communication system applied by the embodiment of the present invention includes that CQI reports triggering equipment (Fig. 1
In by taking eNB as an example) and CQI report triggering equipment (in Fig. 1 by taking UE as an example), wherein can be carried out wireless communication between eNB and UE,
And eNB is for determining MCS when sending data to UE.
In general, eNB is the MCS determined when sending data to UE according to the CQI that receives of the last time, if eNB only root
MCS when sending data to UE is determined according to period CQI.Under the period CQI longer scene of report cycle, the adjacent period twice
The interval time that CQI is reported is longer, and within the interval time that the adjacent CQI of period twice is reported, the channel status of down channel can
It can be varied widely, so eNB may be not suitable for current letter according to the MCS that the last received period CQI is determined
Road state, and then will affect reception of the UE to downlink data.In order to allow UE preferably to carry out the reception of downlink data, this Shen
It please propose a kind of aperiodic scheme for reporting CQI, CQI is allowed to report triggering equipment aperiodic by triggering signaling triggering UE
CQI is reported, to obtain the CQI closer to current channel condition, improves downlink throughput capacity.Trigger condition considers as follows:
The first, reporting for CQI needs to consume ascending resource, and the frequency that CQI is reported is higher, and the ascending resource of consumption is more,
But the downlink space interface gain obtained is bigger.The application obtains balance, setting one in downlink space interface gain and ascending resource consumption
The thresholding of the report cycle of a periodic report CQI, when the practical report cycle of UE is greater than the thresholding, it is non-that triggering UE carries out CQI
Periodic report obtains bigger downlink space interface gain to increase the frequency that CQI is reported.
The second, under the scene for not having downlink data transmission between eNB and UE, if the high-frequency aperiodic CQI of triggering of eNB
It reports, then will increase the signaling overheads between eNB and UE, result in waste of resources；And there is downlink data transmission between eNB and UE
Under scene, if the low-frequency aperiodic CQI of triggering of eNB is reported, eNB may still be not suitable for currently according to the MCS that CQI is determined
Channel status, influence reception of the UE to downlink data.Therefore, a period can be set, screened by the period
UE, and then only allowing in the period has the UE of downlink data to report CQI, reduces ascending resource waste.Therefore, above-mentioned wireless communication
It is provided with two aperiodic trigger thresholds for reporting CQI, first time period and second time period in system, is respectively used to judgement week
Phase reports whether the frequency of CQI reaches thresholding, with trigger it is aperiodic report CQI, and screening has the UE of downlink data aperiodic
Report CQI.For example, first determine whether the report cycle of periodic report CQI and the relationship of the first preset time period, when report cycle not
When less than the first preset time period, detect eNB in the second preset time period whether the UE with downlink data, and under having
The UE of row data sends the aperiodic triggering for reporting CQI to this or these UE and believes as the aperiodic triggering object for reporting CQI
It enables.Give the correct time on triggering aperiodic CQI, combine trigger it is aperiodic on the scene and data transmission service state given the correct time, so
When the embodiment of the present invention there can be downlink data transmission between eNB and UE, eNB is made to obtain the CQI closer to current channel condition；
When there is no downlink data transmission between eNB and UE, without the triggering that aperiodic CQI is reported, so that the wasting of resources is reduced, it can
It is enough to reduce the CQI for obtaining eNB closer to current channel condition.It, can be with as it can be seen that using above scheme
Obtain the balance of the wasting of resources and downlink gain.
It should be noted that the setting of first time period and second time period can be according to the actual conditions or operation of system
The demand of quotient carries out, and the application is not limited with its value.

Wherein, in step s 201, the CQI reports triggering equipment that can specifically obtain UE weeks using the following two kinds mode
Phase reports the report cycle of CQI.
Mode one: when the report cycle of periodic report CQI is that CQI reports triggering device configuration, the CQI reports triggering
Equipment can directly acquire the report cycle of itself configuration；Such as: it is macro base station or the CQI that the CQI, which reports triggering equipment,
Reporting triggering equipment includes the controlled entity for configuring the report cycle of period CQI；
Mode two: when the report cycle of periodic report CQI is that other equipment configure, the CQI reports triggering equipment can
At the time of with by detecting the CQI for receiving CQI reporting equipment periodic report twice in succession, and CQI will be received twice in succession and reported
It is made the difference at the time of the CQI that equipment periodic reports, obtains the report cycle, such as: it is relay base station that the CQI, which reports triggering equipment,
Or the controlled entity of the report cycle for configuring period CQI is located at other apparatus for network node.
S602, the CQI report the relationship that equipment determines the report cycle and the first preset time period that triggers.
After step S602, when CQI reports triggering equipment to judge the report cycle not less than the first preset time period,
Execute step S603；If CQI reports triggering, equipment judges that the report cycle less than the first preset time period, does not trigger CQI
Reporting equipment is aperiodic to report CQI.
S603, CQI report whether triggering equipment detection CQI reporting equipment in the second preset time period has lower line number
According to.
Illustratively, CQI reports triggering equipment whether to detect in the second preset time period CQI reporting equipment to CQI
Reporting equipment is transmitted across data, or CQI reports the spatial cache of the downlink of triggering equipment in the second preset time period
Downlink data comprising CQI reporting equipment, to detect whether the UE in the second preset time period has downlink data.
Wherein, in step S603, the second preset time period can be configured to not according to different scenes and different demands
Same length, when being transmitted across data to CQI reporting equipment in the second preset time period, indicate current CQI report triggering equipment to
It is more frequent that CQI reporting equipment sends data.
In step S603, if the CQI reports triggering, equipment is reported in second preset time period to the CQI
Equipment is transmitted across data, thens follow the steps S204；It is described in the second preset time period that the CQI reports triggering equipment to detect
CQI reporting equipment does not have downlink data, then CQI reporting equipment UE does not report CQI.
S604, CQI report triggering equipment to send the triggering signaling for reporting CQI to the CQI reporting equipment.
Triggering equipment is reported corresponding to the CQI in above-described embodiment, CQI reporting equipment is for executing following steps, reference
