In order that those skilled in the art can be more clearly understood that the technical scheme that the present invention provides, below By specific embodiment, the technical scheme that the present invention is provided is described in detail：

Embodiment one：

A kind of determination method of CSI reference resources is given in the present embodiment.

In the present embodiment, system bandwidth is divided into several subbands, and downstream signal can be according to default Or notice frequency pattern carry out on multiple subbands frequency hopping repeat transmit.Such as send PDSCH, Continuous 10 subframes are transmitted according to default frequency pattern.Frequency hopping can pass through system information Block (System Information Block, SIB) enables, and notifies frequency hopping in such as SIB, or permissible Enable by the way of UE is proprietary, such as notify UE to carry out frequency hopping by DCI.Can define in system Multiple levels of repetition, such as 4, each UE has respective levels of repetition, and UE levels of repetition is really Determine not limit in method the present embodiment.The levels of repetition of such as certain UE is 1, according to the repetition of UE Grade can determine the levels of repetition of this UE each channel corresponding, the levels of repetition of such as each channel with The corresponding levels of repetition of this UE is identical to be also 1, and each levels of repetition of each channel can correspond to a repetition Number of times, the corresponding number of repetition of PDSCH of such as levels of repetition 1 is 10, and levels of repetition is 2 The corresponding number of repetition of PDSCH is 20.The corresponding number of repetition of levels of repetition of different channels is independent , the corresponding number of repetition of PDSCH of such as levels of repetition 1 is 10, the PRACH of levels of repetition 1 Corresponding number of repetition is 12.Under UE receives according to the number of repetition of its levels of repetition each channel corresponding Row signal/transmission upward signal, eNB also sends according to the corresponding number of repetition of levels of repetition of described UE Downstream signal/reception upward signal.Further, for PDSCH/PUSCH, its levels of repetition corresponds to Number of repetition can be generally a kind of basic number of repetition, eNB can adjust reality by DCI The number of repetition on border, floats about the corresponding number of repetition of described levels of repetition.Such as UE repeats Level is 1, and the corresponding number of repetition of PDSCH of levels of repetition 1 is that 10, eNB can be adjusted with 2bit The number of repetition of the PDSCH actual transmissions of UE is one of 8,10,12.

UE determines CSI reference resources according to specified number of repetition and/or frequency pattern, and reports described finger Determine the corresponding CSI of number of repetition.Described frequency pattern is the frequency pattern of Downlink Control Information and/or descending The frequency pattern of data.CSI reference resources include CSI time domain reference resource and CSI frequency domain reference resource. CSI time domain reference resource and CSI frequency domain reference resource refer to the corresponding time-domain resource of CSI that UE reports and Frequency domain resource, that is, the CSI reporting is the CSI in described time-domain resource and frequency domain resource, and such as UE is in son Frame k measures the CSI on full bandwidth, is then reported, then the CSI time domain reference of the CSI reporting Resource is subframe k, and frequency domain reference resource is full bandwidth.

The corresponding specified number of repetition of described CSI can be default, or base station (include NodeB, ENB and low power nodes etc.) notify.Such as, the levels of repetition correspondence that UE is located is default specified Number of repetition, or it is preset as a fixed value, or eNB passes through wireless heterogeneous networks (Radio Resource Control, RRC) signal described specified number of repetition, such as by CSI time domain reference The proprietary indication signaling of resource configures, or for CSI feedback aperiodic, described specified number of repetition is being touched Send out in the DCI of CSI feedback and indicate, or, described specified number of repetition according to Downlink Control Information or The number of repetition of PDSCH determines, such as described specified number of repetition is equal to the descending control letter that UE receives Breath or the number of repetition of PDSCH, or the repetition of the Downlink Control Information for UE reception or PDSCH Number of times correspondence is multiplied by a fixed coefficient, or, described specified number of repetition is true according to PRACH channel Fixed, such as described specified number of repetition corresponding UE sends the levels of repetition that PRACH adopts, such as PRACH levels of repetition is 1, then described specified number of repetition is Downlink Control Information or PDSCH is weighing Corresponding number of repetition during multiple grade 1, is Downlink Control Information or PDSCH corresponds in levels of repetition 1 Number of repetition be multiplied by a fixed coefficient.

Described specified number of repetition can also select in a number of repetition set, described number of repetition collection Conjunction can be default, such as the corresponding number of repetition of all levels of repetition；Or according to default rule Then determine, such as determined it is assumed that UE is located according to the corresponding number of repetition of levels of repetition that UE is located The corresponding number of repetition of levels of repetition be N, then number of repetition collection be combined into 0.5N, 0.8N, N, 1.2N、1.5N、2N}；Or eNB notice, such as notified by RRC signaling or DCI leads to Know.In this case, UE determines specified number of repetition according to default rule, and such as UE is according to upper Give the correct time and quarter select number of repetition, each moment reports one of number of repetition set number of repetition corresponding CSI, poll reports, or UE selects a kind of most suitable specified number of repetition, then reports described finger Determine the corresponding CSI of number of repetition, at this moment, UE also should report the index of described specified number of repetition.

The described CSI that UE reports include following at least one：CQI, pre-coding matrix instruction (Precoding Matrix Indicator, PMI), precoding type indicate (Precoding Type Indicator, PTI), order instruction (Rank Indication, RI).

CSI frequency domain reference resource：

All sons that CSI frequency domain reference resource can comprise for a hop period of described frequency pattern Band.Here described hop period is illustrated.In such as hypothesis system, one has 8 available frequency hoppings Subband, Physical Resource Block (Physical Resource Block, the PRB) number that each frequency hopping subband comprises For 6, index is respectively 0,1,2 ..., 7, the rule of frequency hopping is the subband index being located after frequency hopping It is to 8 deliverys after the subband index at place before frequency hopping adds one, then it is assumed that initial subband is subband #0, then frequency hopping process is：Subband #0, subband #1, subband #2, subband #3, subband #4, subband #5, subband #6, subband #7, subband #0, subband #1 ... it can be seen that subband #0 through 8 times jump It has been returned to subband #0, then subband #0 to subband #7 is called a hop period after frequency.So CSI Reference resources are this 8 available frequency hopping subbands on frequency domain.Again such as it is assumed that available in system Frequency hopping subband for example above-mentioned, the rule of frequency hopping is the place that the subband index being located after frequency hopping is before frequency hopping Subband index add 4 after to 8 deliverys, so, the number of sub-bands of a frequency hopping can only be 2 it is assumed that just Beginning subband is subband #0, then frequency hopping process is：Subband #0, subband #4, subband #0, subband #4 ... is it can be seen that subband #0 is returned to subband #0 after frequency hopping twice, then by subband #0 and son Band #4 is called a hop period.Similarly, be subband #1 and subband #5 is a hop period, for son Band #2 and subband #6 be a hop period, be subband #3 and subband #7 be a hop period. so one It should be two subbands on frequency domain that secondary CSI reports corresponding CSI reference resources, be subband #0 and subband #4, or be subband #1 and subband #5, or be subband #2 and subband #6, or be subband #3 and subband #7.Specifically which two subband, can determine according to default mode, or the side notifying according to base station Formula determines.The present invention does not limit.

CSI time domain reference resource：

Described CSI time domain reference resource is that all subbands that described CSI frequency domain reference resource comprises are corresponding M subframe (M>1), described subframe can be descending physical sub-frame or descending available subframe.Tool Which descending physical sub-frame body is or descending available subframe determines according to default mode, below will be in detail Thin introduction.Here, the available son of subband one or more descending physical sub-frame corresponding/descending Frame refers to that UE is in described subband in the available subframe of this one or more descending physical sub-frame/descending Upper reception downstream signal.

Wherein, described descending available subframe meets at least one condition following：

Described descending available subframe is not within the measurement interval (measurement gap) of configuration；

It should be noted that the determining of subframe in subframe in the other embodiment of the present invention and the present embodiment The identical i.e. subframe of justice can be descending physical sub-frame can also be descending available subframe, and this enforcement In example, the definition of above-mentioned descending available subframe is also suitable in other embodiments of the invention.Described CSI-RS can be CSI-RS of the prior art or define for MTC UE is new CSI-RS, such as only sends in the subband of the reception downstream signal of UE.Described CSI-RS can adopt The default cycle sends in default subframe.The such as cycle is 10, and the subframe of transmission is each radio frames Subframe 2 and 3.
