Embodiment
The inventor notices in the invention process:
At LTE-A (Long Term Evolution-Advance, long-term evolution upgrading) in the system, down-bound pilot frequency signal is divided into CSI RS signal and DMRS (demodulation reference signal, demodulated reference signal) signal, CSI RS signal is used for measuring descending channel information, and DMRS is used for demodulating data.When adjacent many sub-districts send CSI RS signal, usually adopt TDM/FDM (Time DivisionMultiplexing/Frequency Division Mutiplexing, time division multiplexing/frequency division multiplexing) orthogonal manner such as, promptly sub-district CSI RS signal can not run into the CSI RS signal of adjacent sub-district, but the data-signal of meeting and adjacent sub-district collides, as UE (User Equipment, when subscriber equipment) being in cell boarder, CSI RS signal can become more weak, measures this cell channel information and will have error.Another scene is in multipoint cooperative COMP (Coordinated multi-point transmission/reception, cooperative multipoint transmission and reception) transmission.The a plurality of sub-districts of COMP technical support send data to single UE simultaneously, with enhancing UE received signal, thus the demodulation performance of raising UE.In the COMP transmission, UE need measure the signal of a plurality of sub-districts, and all be the UE of cell boarder usually, therefore in order to guarantee the accurate measurement of a plurality of channel informations, some companies propose data cell RE (the resource element of the CSI RS of neighbor cell, Resource Unit) locating data-signal should muting (silence), does not promptly send data-signal.Yet, if do not send data-signal, the CSI RS signal of this sub-district then can not be experienced the interference of adjacent cell data signal, UE measures CQI (Channel Quality Indicator, the channel quality indication) will be inaccurate, because the interference of neighbor cell is normally the strongest,, systematic function is had bigger loss if CSI RS signal can not come out the data interferometry of adjacent sub-district.Another shortcoming that data-signal is muting is the decline of message transmission rate, owing to be muting, the data block available resource units reduces, and valid data transmission information reduces.
In existing technical scheme, mainly be by CRS (Cell-specific reference signals, the exclusive pilot signal in sub-district) interference of signal measurement neighbor cell, the defective of the method is the CRS signal if only be distributed in the control character zone, then can not embody the interference of data area, because in many sub-districts COMP transmission, might use MBSFN (MBSFN Multicast Broadcast SingleFrequency Network, Multicast Broadcast Single Frequency Network) subframe, this moment, the data area did not have the CRS signal, had only the control character zone to have the CRS signal.Fig. 1 is the data and the pilot tone mapping schematic diagram of Serving cell, Fig. 2 is the data and the pilot tone mapping schematic diagram of neighbor cell, as shown in the figure, in the LTE/LTE-A system, control character is arranged in a front 3-4 symbol of subframe, the OFDM of back (Orthogonal FrequencyDivision Multiplex, OFDM) symbol is the data area.In figure below, a subframe contains 14 symbols, 10th, the latticed grid of 11 row is represented CSI RS signal, the RE position that can see neighbor cell and Serving cell is that frequency domain staggers, the 1-3 row are control character zones, the black grid of declivity shape from left to right is CRS signal RE, and the 6th, 7,13,14 perpendicular line shape and band shape, latticed RE position are DMRS RE, and other positions are available data RE.
Channel information and interference estimation method are described below:

0Be noise,, then do not have H if neighbor cell has been made data muting in this position

0Be noise,, then do not have H if Serving cell has been made data muting in this position

As seen from the above analysis, if neighbor cell data RE has been made muting, Serving cell CSIRS signal then is not subjected to the interference of data-signal, can't measure for the interference of adjacent sub-district, but the channel information measurement of Serving cell is more accurate; Same, if Serving cell data RE has been made muting, adjacent sub-district CSI RS signal then is not subjected to the interference of data-signal, and is more accurate for the channel information of adjacent sub-district, but adjacent sub-district is unable to estimate Serving cell and data-signal is disturbed is measured.
Based on this, provide the transmission of a kind of many sub-districts CSI RS and data-signal to receive processing scheme in the embodiment of the invention, below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
Fig. 3 is the transmission processing method implementing procedure schematic diagram of pilot tone and data, as shown in the figure, can comprise the steps: in sending processing procedure
The CSI RS signal location of adjacent sub-district is determined in step 301, base station;
The RE position of data-signal is determined not send in step 302, base station according to the CSI RS signal location of adjacent sub-district;
In the enforcement, when realizing whether data being sent, to be muting this technological means is set will be that example describes with at present commonly used in the following examples, promptly, determine the CSI RS signal location of adjacent sub-district in the base station after, if need on this position, not send data then it is made as muting, obviously, on the position that is not made as muting then still according to predetermined mapping ruler transmission; Need to prove, the purpose that describes with the muting means among the embodiment is to be better to instruct those skilled in the art how to implement the present invention, in fact, so long as can realize the purpose whether the base stations control data send, it also is feasible adopting other means, is not limited in muting mode.
Accordingly, also provide the execution mode of the receiving handling method of the pilot tone of UE side and data in the embodiment of the invention, described below.
Fig. 4 is the receiving handling method implementing procedure schematic diagram of pilot tone and data, as shown in the figure, can comprise the steps: in receiving processing procedure
In the enforcement of above-mentioned transmission and reception processing procedure, determine that the RE position that does not send data-signal that is to say the position of not done the muting setting, then as seen, whether muting can be configured the data RE of CSI RS position as required between different districts, also be, CSI RS signal location according to adjacent sub-district, the partial data signal is carried out muting to be provided with, the partial data signal does not then carry out muting and is provided with, how to carry out the enforcement that part is provided with for better understanding, will describe from the enforcement of frequency domain and time domain respectively with example below.Simultaneously, for the ease of understanding, to combine in the implementation and describe, but, for a person skilled in the art, it also can separately be implemented, when separately implementing, it will solve separately in base station and the existing technical problem of UE side, in conjunction with after then obviously can access better technique effect.
One, go up adjacent sub-district CSI RS location data signal at part PRB (physical resource block, Physical Resource Block) and be muting, data-signal is not muting on part PRB.
At this moment, the implication of part is chosen several PRB with exactlying on frequency domain, suppose that integer is 100 PRB, can select a PRB to be muting on per 2 PRB, also can per 4 selects one, specifically can determine according to the time needs in the enforcement.
In the enforcement, when determining not send the RE position of data-signal according to the CSI RS signal location of adjacent sub-district in the base station, for sending the PRB that data-signal takies, when being adjacent sub-district CSI RS signal location, determine on the RE position, not send data-signal in the data RE position of this PRB.
Concrete, according to the CSI RS signal location of adjacent sub-district data-signal is carried out muting when being provided with in the base station, for the PRB that is set to muting, when being adjacent sub-district CSI RS signal location in the data RE position of this PRB, these data RE position is set to muting, promptly do not send data-signal, other data-signals send as usual.
In the downlink data transmission of base station, for part PRB, if the data RE position of this Resource Block is an adjacent sub-district CSI RS signal location, then this data-signal is muting, data-signal is not muting on part PRB, if promptly these data RE position is an adjacent sub-district CSI RS signal location, data-signal still sends.
In the enforcement, data-signal muting is in CSI RS position, adjacent sub-district on the part PRB that the full range band is spacedly distributed, and does not promptly send data-signal on this Resource Unit.PRB is a kind of data resource unit, is expressed as 12 subcarriers on the frequency domain, is the interval of a subframe in the use.In the RE position of being data-signal muting,, then do not send data-signal on this Resource Unit if there is UE to distribute Resource Unit at resource location.
In the enforcement, when data-signal was set to muting, the number of cells that data-signal muting sky opens is set in CSI RS position can be determined according to many sub-districts CSI RS multiplex mode.Concrete, do the number of cells that data-signal muting sky opens in CSI RS position and can determine according to many sub-districts CSI RS multiplex mode, be generally 3.Data muting opens adjacent sub-district all of the port CSIRS signal in a PRB sky.
In the enforcement, for sending the PRB that data-signal takies, when not sending data-signal on this RE position, the locational PRB index of this RE (index) can generate according to pre-set criteria.With muting is example, for sending the PRB that data-signal takies, when data-signal is set to muting, the PRB index that muting is set can generate according to pre-set criteria, the pre-set criteria of PRB index can be for the PRB index that is spacedly distributed in the system bandwidth that sends at downstream signal, such as being spaced apart 2 or 3.
In the enforcement, when not sending the RE position of data-signal, if it is identical that each sub-district does not send the PRB index transmission subframe of the RE position of data-signal, UE can adopt the mode of agreement to know the PRB index of this position, if different, UE is known the index of the PRB of this position according to the Cell ID of sub-district.With muting is example, for the enforcement of UE side, if the PRB index that each sub-district is provided with muting is identical, the PRB index that UE can adopt the mode of agreement to know to be muting, if different, UE can be known the index of muting PRB according to the Cell ID (cell ID) of sub-district.Concrete, the PRB index that muting is in each sub-district can be identical, also can be different, if it is identical, the UE PRB index that can adopt the mode of agreement to know to be muting then, if different, UE can be known the index of muting PRB according to the Cell ID of sub-district.After UE obtains PRB index, just can do corresponding channel information and estimate and interferometry.
In the enforcement, for COMP user, if send data-signal according to predetermined mapping ruler on the PRB that is distributed, UE can abandon the data-signal that collides with CSI RS signal.With muting is example, and for COMP user, if data-signal is not provided with muting on the PRB that is distributed, UE can abandon the data-signal that collides with CSI RS signal.Concrete, for COMP user, at the Resource Block of transmission data-signal, if data-signal is not muting, data-signal can be subjected to the interference of CSIRS signal, and this moment, UE can abandon the data-signal that these and CSI RS signal collide, in order to improve systematic function.
Find out from above-mentioned enforcement, in the enforcement,, need when sending data-signal, on frequency domain part PRB, be muting the base station.
For UE, know the PRB index of the muting of sub-district earlier, then demodulated data signal not in the position of data muting.
For COMP user, if data-signal is not muting on the Resource Block that is distributed, data-signal can be subjected to the interference of CSI RS signal, and can abandon the data-signal that these and CSI RS signal collide this moment, to improve systematic function.
At last, unite channel information, this cell channel information, the adjacent area interference that estimates adjacent sub-district according to the PRB of muting and the last received signal of PRB of non-muting.
The benefit of this scheme is: more precise channels information estimation can be provided on the PRB of muting, measuring adjacent cell data signal on the PRB that is not muting disturbs, but UE can average the interference on each PRB or Filtering Processing, estimation for channel information also can be carried out Combined Treatment according to the information on a plurality of PRB, extracts channel information more accurately.
Two, select part CSI RS signal to send subframe and be data-signal muting, portion C SI RS signal subframe is not the muting of data-signal.
Under this mode, be that extracting part branch subframe is carried out muting on time domain.
In the enforcement, when determining not send the RE position of data-signal according to the CSI RS signal location of adjacent sub-district in the base station, for the subframe that sends CSI RS signal, when being adjacent sub-district CSI RS signal location, determine on the RE position, not send data-signal in the RE position that sends data-signal.With muting is example, and for the subframe that sends CSI RS signal, when being adjacent sub-district CSI RS signal location in the RE position that sends data-signal, this data-signal is set to muting, and other data-signals are not set to muting.
Concrete, in the downlink data transmission of base station, send the subframe of CSI RS signal for part, if sending the RE position of data-signal is adjacent sub-district CSI RS signal location, then this data-signal is muting, sending in the subframe of CSI RS signal in part, is adjacent sub-district CSI RS signal location if send the RE position of data-signal, and data-signal still sends.
In the enforcement, CSI RS signal subframe muting and non-muting can alternately send.
In the enforcement, when not sending the RE position of data-signal, if it is identical that each sub-district does not send the CSI RS transmission subframe of the RE position of data-signal, UE adopts the mode of agreement to know that the CSIRS of this position sends subframe, if different, UE knows that according to the Cell ID of sub-district the CSI RS of this position sends subframe.With muting is example, when determining to be provided with the signal location of muting, subframe is identical if each sub-district is provided with the CSIRS transmission, the CSI RS that UE can adopt the mode of agreement to know and be muting sends subframe, if different, UE knows that according to the Cell ID of sub-district the CSI RS of muting sends subframe.
Concrete, a plurality of sub-districts of doing the CSI RS subframe of muting can be identical, also can be different, if it is identical, then UE adopts the mode of agreement to know the subframe of being muting, if different, UE is known the position of muting subframe according to the cell ID of sub-district.UE obtains can do corresponding channel information and estimate and interferometry after the muting setting of CSI RS subframe.
In the enforcement, for the subframe that sends CSI RS signal, when being adjacent sub-district CSI RS signal location in the RE position that sends data-signal, determine not send data-signal on the RE position, the index of this CSI RS subframe can generate according to pre-set criteria.Concrete, the index pre-set criteria of CSI RS subframe can be selected equally spaced CSI RS subframe for sending at all CSI RS on the subframe.
In the enforcement, when on the RE position, not sending data-signal, can determine according to many sub-districts CSI RS multiplex mode at the number of cells that this CSI RS position sky is opened.With muting is example, and CSI RS does the position number of cells that data-signal muting sky opens and can determine according to many sub-districts CSI RS multiplex mode, is generally 3.So data muting is meant that space-time is opened adjacent sub-district port CSI RS signal when sending data-signal.
In the enforcement, for COMP user, if send data-signal according to predetermined mapping ruler on the CSI RS transmission subframe of being distributed, UE can abandon the data-signal that collides with CSI RS signal.With muting is example, and for COMP user, if data-signal is not provided with muting on the CSI RS transmission subframe of being distributed, UE can abandon the data-signal that collides with CSI RS signal.Concrete, for COMP user, in the subframe of transmission data-signal, if data-signal is not muting, data-signal can be subjected to the interference of CSI RS signal, and this moment, UE can abandon the data-signal that these and CSI RS signal collide, in order to improve systematic function.
Find out from above-mentioned enforcement, in the enforcement,, need when sending data-signal, on portion C SI RS subframe, be muting the base station.
For UE, the CSI RS of at first knowing the muting of sub-district sends subframe, the demodulated data signal not in the position of data muting is then according to the channel information, this cell channel information, the adjacent area interference that estimate adjacent sub-district in the CSI of the CSI of muting RS and non-muting RS subframe.
The benefit of this scheme is: can measure information more accurately on the subframe of muting, be used for COMP UE and cell boarder UE carries out channel information measurement.On the subframe of not being muting, measure the interference of adjacent cell data signal, also can be used for user's measured channel information of center of housing estate.
Based on same inventive concept, a kind of base station, subscriber equipment also are provided in the embodiment of the invention, because the principle that these equipment are dealt with problems is similar to the receiving handling method of transmission processing method, pilot tone and the data of pilot tone and data, therefore the enforcement of these equipment can repeat part and repeat no more referring to the enforcement of method.
