Fig. 1 shows according to an embodiment of the present invention for measuring the schematic flow chart of the method 100 of CSI, this method It can be executed by the first equipment, wherein first equipment can be UE, but the embodiment of the present invention is without being limited thereto.As shown in Figure 1, This method 100 includes:
S110, the first equipment determine the first measurement frequency band and the second measurement frequency band, and the first measurement frequency band is for carrying out width Band CSI is measured, and the second measurement frequency band is for carrying out subband CSI measurement, wherein the bandwidth of the first measurement frequency band is less than downlink Transmission bandwidth and this first measurement frequency band with this second measure frequency band it is not exclusively be overlapped.
The downstream transmission bandwidth can be downlink system bandwidth, optionally, if first equipment is UE, the downlink transfer Bandwidth can carry out the bandwidth of downlink transfer between at least one serving cell and UE of the UE, wherein the carry out downlink biography Defeated bandwidth can be less than downlink system bandwidth;Or the downstream transmission bandwidth is that another UE and UE carries out equipment and equipment Transmission bandwidth when (Device to Device, D2D) is communicated, but the embodiment of the present invention is without being limited thereto.
The first measurement frequency band is for carrying out broadband CSI measurement, and optionally, broadband CSI measurement may include following survey At least one of in amount: order instruction (Rank Indicator, RI) measurement, broadband precoding matrix indicate (Pre-coding Matrix Indicator, PMI) it measures and is surveyed with broadband channel quality instruction (Channel Quality Indicator, CQI) Amount, correspondingly, the first measurement frequency band are used to carry out at least one in following measurement: RI measurement, broadband PMI measurement and broadband CQI measurement.Preferably, which can be used for carrying out RI measurement and/or broadband PMI measurement, but the present invention is implemented Example is without being limited thereto.
The second measurement frequency band is for carrying out subband CSI measurement, wherein subband CSI measurement may include following measurement At least one of in: subband PMI measurement and subband CQI measurement.Optionally, which may include at least two sons Band, and the second measurement frequency band can be downlink system bandwidth or a part of downlink system bandwidth, but the embodiment of the present invention is not It is limited to this.
The first measurement frequency band is reference resources of the broadband CSI on frequency domain, each subband in the second measurement frequency band For the corresponding CSI of the subband frequency domain reference resources.
S120 is measured in the enterprising line width band CSI of the first measurement frequency band.
The first measurement frequency band enterprising line width band PMI measurement can refer to first equipment assume downlink transfer this first Broadband PMI is selected when on measurement frequency band from code book, and above-mentioned selection may include first equipment according in first survey The selection that the channel measured on amount frequency band carries out;The first measurement frequency band enterprising line width band CQI measurement can refer to this first Equipment assumes that downlink transfer calculates broadband CQI when on the first measurement frequency band;RI survey is carried out on the first measurement frequency band Amount can refer to that first equipment assumes that downlink transfer obtains RI when on the first measurement frequency band or obtains RI and PMI, but this hair Bright embodiment is without being limited thereto.
Optionally, UE, which carries out broadband CSI measurement, to be transient measurement, for example, being measured in a subframe, or should UE carries out broadband CSI measurement respectively over multiple subframes and the measurement result in multiple subframe is carried out statistical disposition, but this Inventive embodiments are without being limited thereto.
S130 carries out subband CSI survey on the second measurement frequency band according to the measurement result that CSI measurement in the broadband obtains Amount.
Wherein, which may include multiple subbands, and correspondingly, first equipment is in the second measurement frequency band Upper progress subband CSI measurement may include at least one of first equipment in multiple subbands that the second measurement frequency band includes Subband CSI measurement is carried out on height band.First equipment can be measured according to RI and/or the measurement result of broadband PMI measurement, Subband CSI measurement is carried out on the second measurement frequency band;The measurement result that can also be measured according to broadband CQI, in second measurement Subband CSI measurement is carried out on frequency band, but the embodiment of the present invention is without being limited thereto.
Optionally, it can be transient measurement that UE, which carries out subband CSI measurement, for example, carrying out subband CSI survey in a subframe Amount, but the embodiment of the present invention is without being limited thereto.
