Mode six, transmitter send two notification messages to receiver, i.e. first notification message and second notification message, wherein, comprise in first notification message RP-RS port and RS port all or part of RE binding relationship or with the binding relationship of all or part of RE of RS resource; Comprise the RP-RS port in second notification message and measure type information.
Wherein, binding relationship can adopt the mode of bitmap mapping or call number to indicate.
The RP-RS resource information can comprise the RP-RS port number of RP-RS resource correspondence, each RS port on time with the corresponding relation of Resource Unit, the period of sub-frame of this RP-RS resource and period of sub-frame bias internal position, the frequency band positional information of this RP-RS resource, etc.
Here, RP-RS can be CRS, CSI-RS, and PRS, MBSFN RS, UE-Specific RS, SRS, the RP-RS resource can comprise the reference signal resource of the reference signal of above-mentioned one or more identical or different types.
Can be that CSI-RS is example with RP-RS, a CSI-RS resource can comprise 4 ports, each time of transmitting this CSI-RS resource use certain pattern pattern determine each port on time with the corresponding relation of Resource Unit, this time can be RB pair (resource block pair).
In one embodiment, the attribute information of reference power reference signal port comprises time domain cycle information and the position offset information in the cycle, the period of sub-frame size of above-mentioned CSI-RS resource is 5 subframes, and the corresponding CSI-RS of transmission, i.e. above-mentioned RP-RS in the 1st subframe (period of sub-frame bias internal position) in each cycle.
In one embodiment, the attribute information of reference power reference signal port comprises subband positional information or the frequency band positional information of frequency domain, the frequency band position of above-mentioned CSI-RS resource can be all subbands or some subbands of whole system bandwidth, namely the RB of all subbands or some subbands pair use above-mentioned pattern pattern determine each port on time with the corresponding relation of Resource Unit.
If the RS port of RP-RS port and a type is bound wholly or in part, then this RP-RS port be with a RS resource at least one port bind wholly or in part, here, RS can be CRS, CSI-RS, PRS, MBSFN RS, UE-Specific RS, SRS.
For instance, the binding relationship of CSI-RS port that comprises all or part of RP-RS port and CSI-RS resource in first notification message, perhaps with the binding relationship of the CRS port of all or part of RP-RS port and CRS resource, the perhaps binding relationship of the Resource Unit of all or part of RP-RS port and CSI-RS resource, the perhaps binding relationship of the Resource Unit of all or part of RP-RS port and CRS resource; Comprise reference power reference signal port in second notification message and measure type information.
In this mode, the resource of RP-RS correspondence can be passed through the RE definition of the RE resource of RE resource, PDSCH correspondence of CSI-RS port, CSI-RS resource, CRS port or CRS resource, PRS port, MBSFN RS port, UE-Specific RS port, PDCCH correspondence and SRS port, SRS resource correspondence.For instance, suppose that the RP-RS resource comprises 2 RP-RS ports, some CSI-RS resources comprise 4 CSI-RS ports, then can be with two CSI-RS port bindings in RP-RS port 0 and 4 the CSI-RS ports in the manner, with two other CSI-RS port binding in RP-RS port one and 4 the CSI-RS ports.Therefore, which kind of transmitter carries out when measuring at the notice receiver at which or which RP-RS port, only need notice RP-RS port and measure type information to get final product, and need not reinform RP-RS port and the corresponding relation of RE combination and the attribute information of RP-RS port, for example notify receiver to adopt the RP-RS port one to carry out RSRP and measure.
Also can be on this basis, notify the attribute information of the corresponding RP-RS port of receiver simultaneously, this moment, the RP-RS port was corresponding with part port or certain RS resource of certain RS resource, the attribute information of receiver RP-RS port as per advice receives RP-RS, rather than receives according to the attribute information of the port of this kind RS.At this moment, the part port of RP-RS port and certain RS resource or certain RS resource are corresponding can be different for the cycle of the port of, cycle of RP-RS port and the RS resource of binding or RS resource, as the former cycle be the multiple in latter's cycle; Perhaps the frequency band position of the port of the frequency band position of RP-RS port and the RS resource of binding or RS resource is different, as what being regardless of the port of binding or the frequency band position of resource, the frequency band position of RP-RS port is 6 RB in center or 72 subcarriers of whole system bandwidth.The scrambling code information of RP-RS port or sequence information also can be different with port or the resource of binding, as port or the corresponding scrambler quadrature of resource of the scrambler of the scrambling code information of RP-RS port of notice or sequence information correspondence and binding.
Adopt this kind mode to notify receiver based on transmitter, correspondingly, first notification message that receiver can receiver/transmitter sends, thereby know the binding relationship between RP-RS port and existing CSI-RS port, CRS port, CSI-RS resource or the CRS resource, also namely known the corresponding relation of RP-RS port and RE combination and the attribute information of RP-RS port.Or obtain the attribute information of RP-RS port simultaneously according to first notification message.Then, second notification message that receiver can receiver/transmitter sends, thus be informed on which or which RP-RS port to carry out which kind of measurement.Then, receiver can be according to the RP-RS port of second notification message notice and binding relationship and the attribute information of described first notification message notice, the RP-RS that receiver/transmitter sends on the transfer resource of correspondence, and carry out the power measurement corresponding with measuring type information according to RP-RS.
Mode seven, transmitter send a notification message to receiver, comprise in this notification message RP-RS port and RS port all or part of RE binding relationship or with the binding relationship of all or part of RE of RS resource, and RP-RS port and measure type information
For instance, the binding relationship that can comprise RP-RS port and CSI-RS port in this notification message, the perhaps binding relationship of RP-RS port and CRS port, the perhaps binding relationship of RP-RS port and CSI-RS resource, the perhaps binding relationship of RP-RS port and CRS resource, and RP-RS port and measurement type information.
The difference of the manner and aforesaid way six is that binding relationship and RP-RS port and measurement type information all are notified to receiver in a message.Similar with aforesaid way six, if the part RE of RP-RS port and RS port binding or with the part RE binding of RS resource, then transmitter also will be notified the attribute information of this RP-RS port of receiver, for example the time-domain position information of this RP-RS port and frequency domain position information etc.
Adopt this kind mode to notify receiver based on transmitter, correspondingly, receiver can be according to the RP-RS port of notice and the binding relationship of notice, the RP-RS that receiver/transmitter sends on the transfer resource of correspondence, and carry out the power measurement corresponding with measuring type information according to RP-RS.If the part RE of RP-RS port and RS port binding or bind with the part RE of RS resource, then receiver can be according to the attribute information of RP-RS port, binding relationship and this RP-RS port of transmitter notice, the RP-RS that receiver/transmitter sends on the transfer resource of correspondence, and carry out the power measurement corresponding with measuring type information according to RP-RS.
In mode six or mode seven, each RP-RS port can corresponding 1/2 port the CSI-RS resource, totally 32 ports, then transmitter can adopt the RP-RS port that the bitmap notice receiver of 32bit can be used, when transmitter notice receiver carries out power measurement, can adopt 5bit to notify receiver to use which the RP-RS port in 32 RP-RS ports to carry out which kind of measurement.
Need to prove, transmitter is when the RP-RS port that the notice receiver can be used, can notify one or more RP-RS port, can which kind of carry out when measuring at which RP-RS port at the subsequent notification receiver, also can notify one or more RP-RS port.For instance, 5 RP-RS ports that transmitter can notify receiver to use, this notice make receiver can know the full detail with these 5 RP-RS ports, for example its RE resource corresponding on time, location information domain at that time, frequency domain position information etc.When the subsequent transmission machine needs receiver to carry out the CQI measurement, transmitter can be notified on receiver 2 RP-RS ports therein and carry out the useful signal of CQI or the measurement of interference signal, and the final result who measures for example can be for measuring the mean value that obtains power on these 2 RP-RS ports.Or notify and carry out the useful signal of CQI or the measurement of interference signal at a RP-RS port, receiver is used for the performance number of measuring the calculating of this CQI after measurement.
In network, network terminal can measure correct power information for receiver, can on the transfer resource of the RP-RS port that corresponding receiver measurement power on all or part of network node of network side is used, correspondence transmit certain signal, carry out corresponding power measurement to cooperate receiver.When measuring interference as receiver, all or part of node of network side can be measured the certain signal of transmitted over resources that disturbs at the receiver of correspondence, thereby receiver can measure the interference of corresponding node.

In the present embodiment, suppose that the signal section of two CQI correspondences is identical, the interference sections difference.Wherein, the useful signal part can be measured at the corresponding RE of the CSI-RS of 4 ports resource (using CSI-RS Config 1).Interference sections can be measured at RP-RS port 0 and RP-RS port 1.Wherein, RP-RS port 0 can be corresponding with the RE of the CSI-RS Config 0 of 4 ports, RP-RS port1 can be corresponding with the RE of the CSI-RS Config 5 of 4 ports, perhaps RP-RS port 0 is corresponding with the RE of the CSI-RS Config 0 of 4 ports, the port one 9/20 among the CSI-RS Config 0 of RP-RS port 1 corresponding 8 ports.RP-RS port is corresponding certain time domain and frequency domain position information of while also, as identical with the time-frequency domain positional information of the CSI-RS resource that comprises its corresponding CSI-RS port.
Transmitter can be notified to receiver with two RP-RS ports of RP-RS by the RRC signaling.
Step 302, transmitter notice receiver are measured interference sections at two RP-RS ports, go up the measuring-signal part in the CSI-RS of 4 ports resource (using CSI-RS Config 1).
Receiver can be determined the RE of RP-RS port 0 correspondence and the RE of RP-RS port 1 correspondence according to the configuration information of knowing in the step 301 after the notice of receiver/transmitter.Then, receiver can carry out interferometry respectively on two RP-RS port, carries out the measurement of useful signal part at the CSI-RS of 4 ports Config 1.
Step 303, receiver are calculated two CQI respectively and are fed back to transmitter according to the interference sections that the signal section that measures in CSI-RS resource (using CSI-RS Config 1) and two RP-RS ports measure.
Specifically, receiver can be measured reception signal and the total signal that receives of corresponding CSI-RS at the RE of RP-RS port 0 correspondence, the reception signal that the last corresponding total reception signal of each RE is deducted corresponding CSI-RS namely can be used as the interference signal that this RE goes up correspondence, the power of the interference signal that measures on each RE is averaged, as arithmetic mean, as the interference signal of calculating corresponding CQI.And receiver can be measured useful signal the CSI-RS of 4 ports resource (using CSI-RS Config 1), and is last, and receiver can calculate corresponding CQI according to useful signal with in the interference signal that RP-RS port 0 measures.
Receiver can be adopted in a like fashion and measure interference signal and measure useful signal in the CSI-RS of 4 ports resource (using CSI-RS Config 1) at RP-RS port 1, and calculates corresponding CQI.Receiver can feed back to transmitter with these two CQI.
Need to prove that in the present embodiment, two RP-RS port also can be used for measuring the useful signal part, and adopt other RE to measure interference sections.
In addition, it will be appreciated by persons skilled in the art that step 301 and step 302 in the present embodiment can adopt aforementioned seven kinds of modes to notify receiver equally.

Step 401, obtain the metering system of signal measurement.
Step 402, the described metering system of employing carry out signal measurement at the transfer resource of described signal measurement correspondence.
Specifically, in existing communication system, the resource that can be used for signal measurement can comprise zero energy CSI-RS or non-zero power CSI-RS.And in some cases, transmitter may be notified the user a plurality of CSI-RS resources, and in these resources, zero energy CSI-RS resource be may have and identical RE position or identical CSI-RS config. number used with non-zero power CSI-RS resource, when corresponding these RE carry out signal measurement, may adopt different metering systems so.But, in the prior art, transmitter can only be notified receiver measuring-signal on which resource, but when same resource needs to adopt different metering systems to carry out signal measurement, receiver does not also know how to carry out signal measurement, thereby occurs the inaccurate problem of signal measurement often.
Accordingly, in the present embodiment, receiver can obtain the metering system of signal measurement, and receiver can adopt this metering system to carry out signal measurement at the transfer resource of described signal measurement correspondence then.
In the present embodiment, receiver can obtain the metering system of this signal measurement before carrying out signal measurement, thereby adopted described metering system to carry out signal measurement at the transfer resource of described signal measurement correspondence, thereby can be so that signal measurement is comparatively accurate.
Method embodiment shown in Figure 4 is the technical scheme that receiver is realized, and correspondingly, for transmitter, it can send indication signaling to receiver, the metering system that comprises signal measurement in this indication signaling is so that described receiver adopts described metering system to carry out signal measurement at the transfer resource of described signal measurement correspondence.
Specifically, transmitter can send indication signaling to receiver, carries out the metering system of signal measurement to indicate receiver, and then, receiver can adopt the metering system that obtains to carry out corresponding signal measurement.
In the present embodiment, transmitter can indicate receiver to carry out the metering system of signal measurement, thereby makes receiver can adopt this metering system to carry out corresponding signal measurement, and then can be so that signal measurement is comparatively accurate.
When specific implementation, at zero energy CSI-RS, its corresponding metering system can carry out signal measurement as the signal of directly measuring for the signal that will receive, and at non-zero power CSI-RS, its corresponding metering system can carry out signal measurement as the signal of directly measuring for will deduct signal after the decodable code part (as the signal of the non-zero power CSI-RS of correspondence) from the signal that receives; Perhaps, at zero energy CSI-RS, its corresponding metering system can be for carrying out signal measurement with transfer resource as the zero energy reference signal, and at non-zero power CSI-RS, its corresponding metering system can be for carrying out signal measurement with transfer resource as the non-zero power reference signal.In addition, transmitter can also use transfer resource as carrying out signal measurement as the zero energy reference signal with regard to notifying when the notification transmission resource, still transfer resource is used as carrying out signal measurement as the non-zero power reference signal.Wherein, this non-zero power reference signal can comprise: the combination in any of the RE of the RE of the RE of the RE of the RE of CSI-RS port correspondence, CSI-RS resource correspondence, the RE of CRS port correspondence, CRS resource correspondence, the RE of PRS port correspondence, MBSFN RS port correspondence, RE, the RP-RS of UE-Specific RS port correspondence and SRS port correspondence or the RE of SRS resource correspondence.

Expression rounds up to x, and M goes up corresponding CSI-RS quantity, 2 of described indicating bit for the same RE of notice receiver NIndividual state is respectively applied to represent the different reference signals on the described same transfer resource are carried out the metering system of signal measurement, represents to measure the reception signal that need deduct this indicating bit corresponding reference signal when disturbing from total reception signal as each indicating bit; Perhaps, N equals the quantity of corresponding reference signal on same transfer resource, each bit is used for sign and carries out the metering system of signal measurement according to the reference signal on the transfer resource corresponding with this bit, deducts all corresponding bit positions when disturbing as measuring and be the reception signal of 1 reference signal from total reception signal.
The another kind of metering system of present embodiment can carry out descrambling to the signal of reception for adopting with the scrambler phase quadrature of transmitter scrambling or identical scrambler, and with the signal behind the descrambling as the signal of directly measuring.
Specifically, employed scrambler was identical when employed scrambler when transmitter can notify receiver to carry out descrambling, this scrambler not necessarily carried out scrambling with transmitter to signal, and concrete advice method can generate initiation parameter for notification sequence.When the scrambler quadrature of the scrambler of the descrambling of transmitter notice and scrambling, receiver will be by receiving the signal that obtains behind the signal descrambling, when for example the signal that measures on the RE of CSI-RS correspondence averages, be zero after the part of CSI-RS correspondence adds up or approximate zero, thus signal power or interference power only beyond the remaining CSI-RS.For example, the corresponding CSI-RS port of RP-RS port, the scrambler that the transmitter scrambling is used is X 1, X 2..., X N, if the scrambler of the descrambling that transmitter notice receiver uses is Y 1, Y 2..., Y N, ∑ (X wherein 1* Y 1)=0, also be the scrambler of scrambling and the scrambler quadrature of decoding, when the signal behind descrambling this RP-RS port measured of receiver adds up so, the signal section of corresponding CSI-RS is accumulated as zero or approximates zero, so the power of measuring does not comprise the power of corresponding CSI-RS, also be about to signal behind the descrambling as the signal of directly measuring.

For instance, it is a non-zero power CSI-RS resource that transmitter can be notified receiver CSI-RS resource, and to have notified the CSI-RS resource simultaneously be zero energy CSI-RS resource.
Transmitter is when the CQI that the notice receiver need feed back, can notify receiver to adopt two kinds of metering systems to measure interference signal in the CSI-RS resource, a kind of interference signal is calculated CQI (node is the receiver service in the respective cell scope) for total reception signal of directly measuring on the CSI-RS resource as interference signal, and another kind of interference signal is calculated another CQI (another node in the respective cell scope is the receiver service) for the total reception signal on the CSI-RS resource being deducted the corresponding CSI-RS signal that receives as interference signal.
Step 502, receiver are measured in the interferometry mode of measuring the resource use correspondence of disturbing, and are calculated corresponding CQI.
If when the interferometry mode of transmitter notice was maybe carried out interferometry with this resource as the zero energy resource for the reception signal that will directly measure as interference signal, the signal that receiver can directly measure all RE in this resource correspondence carried out the calculating of corresponding CQI as interference signal.
When if the interferometry mode of transmitter notice is maybe carried out interferometry with this resource as the non-zero power resource for will deduct the back at the RS that corresponding resource receives from the resultant signal that receives as interference signal, receiver carries out the calculating of corresponding CQI with residual signal can deduct the RS signal that corresponding resource receives from the resultant signal that receives after as interference signal.
Step 503, receiver feed back to transmitter with CQI.
