For the M- subframes for sending CRS, in the part subframe that M- subframes are included, there is CRS, no CRS in the subframe of part,In a M- subframe, only part subframe sends CRS, such as in one M- subframe, only subframe 0,2,4Send CRS.CRS in each subframe can be that existing CRS is designed, or newly-designed CRS, for example,The allocation plan of the CRS in subframe in alternative embodiment four.
Alternative embodiment six：
For the UE for needing coverage enhancement, such as close to the sensor etc. of basement, its covering is often very poor, to UEThe signal of transmission generally requires the requirement that substantial amounts of repetition could meet BLER.A method for reducing number of repetition is to increasePlus the density of reference signal, and if the UE of the indivedual coverage enhancements in for system increases the density of CRS, for wholeFor individual system, very big waste can be caused.Therefore a kind of sending method of CRS is provided in the present embodiment.
In this alternative embodiment, the transmission of CRS is divided into two parts, i.e. the first reference signal and the second reference signal.Send outThe running time-frequency resource of the first reference signal is sent to be referred to as the first running time-frequency resource, the first running time-frequency resource is predefined or half is quietState configuration, the first reference signal is sent by N number of antenna port.Send such as according to the method for above-described embodiment,Such as send in the M- subframes that MIB is located, in the M- subframes that MIB is located, a transmission antenna port 0, andOnly send on two symbols in time domain；Or according to the prior art transmission of similar LTE, such as non-MBSFN'sSend in M- subframes, in all subframes in each M- subframe, CRS is sent according to prior art.Send second to refer toThe running time-frequency resource of signal is the second running time-frequency resource.
The antenna port of second reference signal can be entirely different with the antenna port of first reference signal, also may be usedIt is identical with part.The transmission antenna port of such as the first reference signal is 0,1, sends the antenna of second reference signalPort is 2,3.
Further, during the antenna port of second reference signal can be the antenna port of first reference signalPart or all antenna ports, i.e., on one or more antenna port of N number of antenna port, send secondReference signal.One or more antenna port of N number of antenna port is default or eNB is notified.
Second running time-frequency resource is determined from base station to time-domain resource and/or frequency domain resource that designated terminal sends downstream signal.ThanSend as the second reference signal sends full bandwidth in the time-domain resource of downstream signal in the designated terminal, or only describedDesignated terminal sends, and such as described designated terminal is in PRB#3～7 of subframe #3Upper transmission, then the second reference signal is only sent on PRB#3～7 of subframe #3.Here designated terminal is specified typeTerminal, be such as the terminal of low cost, or to need the terminal of coverage enhancement；Or designated terminal is to specify biographyTerminal under terminal under terminal under defeated pattern, such as coverage enhancement pattern, or big coverage enhancement pattern, Huo ZheweiTerminal in high speed mode etc..In practical application, the example above is not limited to.Or designated terminal can also be to have receivedThe terminal that eNB is notified, such as eNB notify the time domain money that eNB described in UE can be located in the downstream signal of the UEThe second reference signal is sent on source and/or frequency domain resource.Such as the UE in coverage enhancement pattern, in the son which transmitsFrame, except sending the CRS on the first running time-frequency resource, can also send CRS on the second running time-frequency resource.When assuming firstCRS in frequency resource has the individual antenna ports of N (>=1), then in the subframe that the UE of coverage enhancement is transmitted, theOn two running time-frequency resources, CRS is sent on all or part of antenna port of N number of antenna port.So, coveringIn the transmission subframe of the UE of enhancement mode, the density of the reference signal of part or all of CRS antenna ports increased,Improve the demodulation performance of UE under coverage enhancement.In practical application, the UE being not limited under coverage enhancement pattern.Enter oneStep ground, the second running time-frequency resource and the first running time-frequency resource are not overlapped.
Further, in transmission to coverage enhancement UE (UE under coverage enhancement pattern is not limited in practical application)Before the second reference signal is sent on frame, eNB can pass through high-level signaling or DCI notifies that eNB can be in the second time-frequencyReference signal is sent in resource.UE is notified such as in SIB, and which can be in the son at the downstream signal of coverage enhancement UE placeOn frame on the second running time-frequency resource sending signal, so, coverage enhancement UE receive signal when can receive first simultaneously whenReference signal in frequency resource and the second running time-frequency resource.By 1bit signalings notifying such as in SIB, " 1 " representsENB can send reference signal on the second running time-frequency resource in the subframe that downstream signal is sent to coverage enhancement UE, " 0 "Represent that eNB will not send reference signal on the second running time-frequency resource in the subframe that downstream signal is sent to coverage enhancement UE.Or, eNB can also notify certain UE in RRC signaling, and which can be in the subframe that the downstream signal of UE is located theReference signal is sent on two running time-frequency resources.
Or, the second running time-frequency resource can also be determined by the PDSCH sent to UE (hereinafter referred to a UE).EnterOne step ground, the second running time-frequency resource is determined according to the number of repetition of the PDSCH, such as when the repetition of the PDSCHDuring the thresholding that number of times is preset more than/configured, eNB then can send second in the running time-frequency resource that the PDSCH is locatedReference signal.Or, can be in the PDSCH of UE comprising eNB in the Downlink Control Information DCI of scheduling PDSCHThe configured information of reference signal is sent in the subframe at place on the second running time-frequency resource.Or, the second running time-frequency resource is according to instituteType/the transmission mode for stating UE determines that the type/transmission mode of the UE is as defined above to be stated, and such as increases for coveringUE under strong mode, eNB then can send the second reference signal in the running time-frequency resource that the PDSCH is located.Enter oneStep ground, before sending the second reference signal in the transmission subframe to the PDSCH of the UE, eNB can lead toCross high-level signaling or DCI notifies that eNB can send reference signal on the second running time-frequency resource.
Or, the second running time-frequency resource can also be determined by the Downlink Control Information sent to UE (hereinafter referred to the 2nd UE).Further, the second running time-frequency resource according to the number of repetition of the Downlink Control Information determine, such as when the descending controlDuring the thresholding that the number of repetition of information is preset more than/configured, eNB then can be at Downlink Control Information placeThe second reference signal is sent in frequency resource.Or, determined according to the form of the Downlink Control Information, such as under describedDuring the thresholding that the bit number that row control information is included is preset more than/configured, eNB then can be in the descending control letterThe second reference signal is sent in the running time-frequency resource that breath is located.Or, type/transmission of second running time-frequency resource according to the UEPattern determines that the type/transmission mode of the UE is as defined above to be stated, such as the UE under coverage enhancement pattern,ENB then can send the second reference signal in the running time-frequency resource that the Downlink Control Information is located.Further, to instituteBefore the second reference signal is sent in the transmission subframe of the Downlink Control Information for stating UE, eNB can be by high-rise letterOrder or DCI notify that eNB can send reference signal on the second running time-frequency resource.
The corresponding pattern of antenna port and/or antenna port of the second reference signal can be it is default, such as base station according toThe type of designated terminal/the 2nd UE described in a UE/, determines the antenna port and/or antenna end of the second reference signalThe corresponding pattern of mouth.Such as designated terminal is the terminal under coverage enhancement, then eNB is using corresponding day during coverage enhancementLine end mouth and/or the corresponding pattern of antenna port are sending CRS.Or, according to the PDSCH or described to UEDetermining, such as number of repetition is bigger, and pilot tone is closeer for the number of repetition of the Downlink Control Information of transmission, i.e. each scheduling is singleThe RE numbers for being used for second reference signal in unit are more.Or, according to the descending control sent to UEThe form of information processed determines that the bit number that such as described Downlink Control Information is included is more, and pilot tone is closeer.Or, rootThe preamble sent during according to the terminal Stochastic accessing determines.Each preamble can correspond to described second with reference to letterNumber the corresponding pattern of antenna port and/or antenna port.
The corresponding pattern of antenna port and/or antenna port of the second reference signal can also be configuration, such as in SIBMiddle notice, or in above-mentioned instruction eNB can send the first high-level signaling of reference signal on the second running time-frequency resource orNotify in DCI, or notify in another high-level signaling for be different from first high-level signaling.Or, it is also possible toNotify in the RAR received during UE Stochastic accessings or message four.
Alternatively, in order to ensure compatibility, the second running time-frequency resource position can be in the position of the CRS from correlation techniqueMiddle selection, that is to say, that the second running time-frequency resource position can be the subset of following RE set S：In each time slotFrequency domain interval on 1, the 2nd and 3rd symbol reciprocal is 4 RE of 2 RE, the initial RE positions of REPut and determined by cell ID.Original position isIndividual RE, wherein, symbol is sequentially in timeStart sequence from 1, RE starts sequence from 1 to highest order from frequency is minimum according in frequency.Fig. 9 is according to thisThe schematic diagram one of the RE set S of invention alternative embodiment, as shown in figure 9, in the corresponding RERE set of grid linesRE。
For example, Figure 10 is the first reference signal of transmission and the signal of the second reference signal according to alternative embodiment of the present inventionFigure, as shown in Figure 10, a M- subframe includes 6 subframes, and each subframe includes a PRB, in each M-In each subframe of frame, CRS is being sent on 0 corresponding RE of antenna port in the prior art, antenna port is 0,In the subframe of coverage enhancement UE transmission, in the prior art on 0 and 1 corresponding RE positions of antenna port, all in dayCRS is sent on line end mouth 0.
Or, in each subframe of each M- subframe, send antenna port 0 of the prior art and antenna port 1On CRS, coverage enhancement UE transmit subframe, all in antenna on 0 and 2 corresponding RE positions of antenna portCRS is sent on port 0, antenna port all sends CRS on antenna port 1 on 1 and 3 corresponding RE positions.
Further, for coverage enhancement UE, in order to further increase the density of CRS, ensure compatible again, secondRunning time-frequency resource can be the subset of the RE set S1 that existing DMRS is located, i.e., be located in existing DMRSRE is upper to send CRS on all or part of antenna port of N number of antenna port.The RE collection that existing DMRS is locatedIt is combined into：
