Description
Technical field
The present invention relates to communication technical field, particularly a kind of control treatment method that reports of CQI of reporting, CQI and device.
Background technology
Adaptive modulation and coding (Adaptive Modulation and Coding, AMC) is a kind of link adaptation techniques of physically based deformation layer.In Long Term Evolution (Long Term Evolution, LTE) system, descending AMC control procedure be subscriber equipment (User Equipment, UE) by detecting descending public reference signal, carry out down channel quality measurement; UE is by channel condition information (Channel StateInformation, CSI) network side is fed back to by feedback channel, network side is according to the channel condition information of feedback, carry out corresponding downlink transfer modulation coding mode (Modulation and Coding Scheme, MCS) Format adjusting.The corresponding various order of modulation of MCS form and code rate, when changes in channel conditions, system needs to select different MCS schemes to change the impact brought with adaptive channel according to channel condition.Good MCS scheme target reaches the data rate of transmission and the trend consistency of channel variation, and system can utilize the transmittability of wireless channel substantially, improves the throughput of system.Therefore the CSI that UE feeds back to network side just seems particularly important, CSI comprises: channel quality instruction (Channel Quality Indication, CQI), pre-encoding quality instruction (Pre-coding Matrix Indication, and the order instruction content such as (RankIndication, RI) PMI).Wherein of paramount importance key parameter is CQI, its instruction under different channels quality, institute advise use best modulation system and code check.
In LTE system, CQI reports process as follows: the measurement first carrying out CQI, wherein, up by measuring demodulated reference signal (Demodulation Reference Signal, DMRS) signal and interference and noise ratio (Signal to Interference plus Noise Ratio, SINR), obtain corresponding CQI index (index) by algorithm, network side obtains the metrical information of CQI by tabling look-up; Descending reference signal of being specified by measurement community is at non-multicast single frequency network (Multicast Broadcast Single FrequencyNetwork, MBSFN) subframe and MBSFN reference signal are at the SINR of MBSFN sub-frame, corresponding CQI index is obtained by algorithm, CQI index is fed back to network side, and network side is by acquisition channel information of tabling look-up.Secondly, carry out reporting of CQI, can adopt the cycle and aperiodic two kinds of modes report.Periodic CQI is reported and is normally undertaken by physical uplink control channel (Physical Uplink ControlChannel, PUCCH).If UE has been scheduled in the subframe sending periodic CQI simultaneously, data need to send, now, UE incites somebody to action ink Shared Channel (Physical UplinkShared Channel physically, PUSCH) to adopt in and in CQI on PUCCH, same CQI format carries out reporting of CQI, and accordingly PUCCH resource can be on the shelf.Acyclic CQI reports and is triggered by evolved base station (evolved NodeB, eNB), reports and is undertaken by physical down link sharing channel (PhysicalDownlink Shared Channel, PDSCH).Reporting of this CQI can send separately on PUSCH, also can send together with data.Report the simultaneous subframe of subframe in cycle and aperiodic CQI, UE only reports aperiodic CQI and abandons the CQI in cycle.
Above-mentioned LTE system only considers the connected state business of point-to-point, and therefore UE only reports CQI at connected state.But for the group-calling service feature of group system point-to-multipoint, namely calling UE only has one, called have multiple, and all called UE share downlink traffic channel, and called UE may be distributed on multiple place.Consider that the service feature of this point-to-multipoint is different from the point-to-point service feature of LTE system, even if multiple called UE is at Idle state, also can there is Business Processing.Therefore, from the angle of self adaptation accuracy and real-time, even if also need to report CQI to the situation of network side at Idle state for UE in group system, adopting which kind of mode to be reported by CQI is better group system good problem to study.
For multiple UE of group system group calling, when existence is in the UE of Idle state, the agreements such as CQI how are reported not to be further described.If UE needs to report CQI to network side at present, can only report when UE is in connected state, therefore general all directly employing realizes in the mode of the fixing empirical value of network side configuration.Although which realizes simple, but deviate from the target of adaptive technique, the requirement of closed-loop adaptation system cannot be reached, system call interception acquired results namely cannot be utilized to go the performance of optimization system.Main manifestations is as follows:
First, the point multipoint message traffic feature of cluster, requires that all UE in group share downlink traffic channel, therefore needs all UE all should report CQI, uses so that network side does scheduling to downlink business.But because LTE system cannot report network side for the CQI information of Idle state UE, therefore network side can only obtain the CQI value reported when UE is in connected state, this value can not actual feedback current channel condition quality information, there is larger deviation, cause the deviation that modulation levels and code rate are selected, directly have influence on the accuracy of self-adaptative adjustment, the throughput of band utilization efficiency and group system can not be improved to greatest extent.
Secondly, if adopt configuration fixed value mode, the modulation levels of now network side configuration and coded system can not meet the conditional request of self-adaptative adjustment completely, often occur when channel quality is very poor time, still select larger modulation system and code rate; When channel quality is good, select less modulation system, thus reduce the utilization ratio of frequency band, the throughput of group system cannot be promoted.
In sum, in prior art, UE reports CQI to network side, can only report, and corresponding CQI cannot be reported when UE is in Idle state to network side, deviate from the requirement of link adaptation techniques when UE is in connected state.

Cluster UE reports the trigger condition of CQI as follows:
Frequently selection scheduling is one of key technology of link adaptation techniques, and selection scheduling is closely-related with the acquisition of CQI frequently, and selection scheduling can adopt periodicity to report to report two kinds of modes with aperiodicity frequently.For each business characteristic of group system, consider the following scheme of design:
(1) speech business: the i.e. PUSCH transmission of semi-continuous scheduling (as VoIP), uses non-frequency selection scheduling, be configured to periodic triggers CQI and report.
(2) video and large-data operation: adopt non-frequency selection scheduling, configurable aperiodicity triggers CQI and reports.
When more than there is business datum process, UE is in connected state, and therefore the process that reports of its CQI can with reference to current protocol realization.
The technical scheme of CQI is reported to be described below in conjunction with accompanying drawing to the Idle state UE that the embodiment of the present invention provides.
In UE side, see Fig. 1, a kind of method reporting CQI that the embodiment of the present invention provides, comprising:
S101, UE, when being in Idle state, determine to need to report CQI;

Mode two: when the value of the CQI recorded when described UE is current does not belong to the CQI span belonging to value of the CQI that the last time reports, described UE determines to need to report CQI.
Preferably, described CQI span is one that divides into groups in multiple CQI spans of obtaining to all values of CQI in advance, a kind of coded system that the corresponding PDSCH of each CQI span supports.
At present, the coded system that PDSCH supports has three kinds: be respectively QPSK, 16QAM and 64QAM, and its coded system is different, and required channel condition is not identical yet, and coded system is higher, needs the channel condition of dependence better.
Preferably, all values of CQI are divided into three groups, wherein 1-6 is one group, corresponding QPSK; 7-9 is one group, corresponding 16QAM; 10-15 is one group, corresponding 64QAM.
Such as, the value of the CQI that the last time reports is 12, and the CQI span belonging to it is 10-15, and the value of current measured CQI is 4, do not belong within the scope of 10-15, therefore UE determines to need to report CQI.
Mode three: when described UE reports instruction as the CQI receiving network side transmission, described UE determines to need to report CQI.
Wherein, described CQI reports instruction, can be the updating message of the multiple CQI spans obtained of dividing into groups to all values of CQI notified by system broadcasts, also can be an independent indication bit position.Such as, a bit is set and is used to indicate UE and carries out CQI and report, when the value of this bit is 0, represent that UE does not need to report CQI; When the value of this bit is 1, represent that UE needs to report CQI.
