Description

A kind of interference detecting method, network equipment and terminal side equipment
Technical field
The present invention relates to wireless communication technology, particularly relate to a kind of interference detecting method, network equipment and terminal side equipment.
Background technology
Presence of intercell interference is an intrinsic problem of cell mobile communication systems, and traditional solution adopts channeling, by allowing neighbor cell use different carrier frequency, avoids the interference problem between neighbor cell.At OFDM (OFDM, Orthogonal Frequency Division Multiplexing) in system, frequency reuse is 1, and namely neighbor cell uses identical carrier frequency, and the problem of inter-cell interference brought also can be more complicated than traditional frequency reuse system.Long Term Evolution (LTE, Long Term Evolution) be system based on OFDM technology, the randomization of main employing presence of intercell interference, interference are avoided solving interference problem with coordination technique, by the mode such as precoding, cooperative scheduling of network side, realize avoiding of interference at transmitter side.But the interference based on transmit leg cooperates, depend on the accuracy of the channel condition information (CSI, Channel State Information) of feedback to a great extent.By the restriction of feedback signaling overhead and the impact of feedback processing time delay, current LTE system not can solve interference problem based on the method for transmit leg interference cooperation, how effectively eliminating and to suppress the interference between minizone and user, is the follow-up important directions effectively improving spectrum efficiency further.
In LTE system, employing be that public reference signal (CRS, Common Reference Signal) carries out pilot measurement and data demodulates, namely all users use CRS to carry out channel estimating.Adopt concrete pre-coding matrix (also can the be called precoding weights) information used when needing transmitting terminal additional notifications receiving terminal data to send during the precoding processing mode based on CRS, and the expense of pilot tone is larger.In addition in multi-user's multiple-input and multiple-output (MU-MIMO, Multi-user Multi-input Multi-output) system, because multiple terminal uses identical CRS, the orthogonal of pilot tone cannot be realized, be therefore unable to estimate interference.
Long Term Evolution (the LTE-A strengthened, Advanced Long Term Evolution) in system, in order to reduce pilot-frequency expense and improve channel estimation accuracy, pilot measurement and data demodulates function are separated, respectively define two class reference signals: demodulated reference signal (DMRS, Demodulation Reference Signal) and channel state information reference signals (CSI-RS, Channel State Information Referenced Signal).Wherein CSI-RS is mainly used in channel measurement to obtain channel quality information (CQI, Channel Quaulity Information) and feed back, make base station side that this information completing user can be utilized to dispatch and complete Modulation and Coding Scheme (MCS, Modulation and Coding Scheme) self-adjusted block, do not carry precoding information in the transmission of CSI-RS; And DMRS is mainly used in Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) and strengthen Physical Downlink Control Channel (ePDCCH, enhanced Physical Downlink Control Channel) channel estimating to complete the demodulation of data/control channel, the transmission of DMRS carries the precoding information of corresponding PDSCH/ePDCCH.LTE and lte-a system can be divided into Frequency Division Duplexing (FDD) (FDD according to the difference of up-downgoing duplex mode, Frequency Division Duplex) and time division duplex (TDD, Time Division Duplex) system, the pattern of CSI-RS and DMRS of FDD and TDD system can difference to some extent.
The least resource unit that resource element (RE, Resource Element) is downstream transmission, the position in PRB can represent with two-dimensional coordinate (k, l), and wherein k is subcarrier in frequency domain index, and l is time-domain OFDM symbol index.For ePDCCH, define two kinds of special control channel resource units: the resource grains subgroup (eREG of enhancing, enhanced Resource Element Group) and strengthen control channel particle (eCCE, enhanced Control Channel Element).A PRB can be divided into 16 eREG according to the numbering of RE sequence 0 to 15, be numbered 0, 4, 8, the eREG of 12 classifies as eREG group0, be numbered 1, 5, 9, the eREG of 13 classifies as eREG group1, be numbered 2, 6, 10, the eREG of 14 classifies as eREG group2, be numbered 3, 7, 11, the eREG of 15 classifies as eREG group3, eCCE can be made up of (namely each eREG group corresponds to 1 eCCE) or 8 eREG and form that (8 eREG being numbered even number form 1 eCCE 4 eREG, 8 eREG being numbered odd number form other 1 eCCE), as shown in Figure 3.
In the senior receiver research of receiving terminal, the performance of receiver depends on the accuracy of interferometry to a great extent, and current existing LTE and lte-a system well can not support that interferometry is for data demodulates accurately.Although introduce interferometry resource (IMR in the LTE-A Rel-11 stage, Interference Measurement Resource) for the channel condition information of measurements interference signal, but this signal is mainly used in the measurement of CQI, the transmission cycle is long, and cannot the interference of every one deck of measurement data, therefore interference is eliminated and suppresses and when not being suitable for data channel/control channel demodulation, and how improving the interferometry effect of data channel/control channel, is have problem to be solved.

In LTE/LTE-A system, the Received signal strength (N of receiver on a kth subcarrier and l OFDM symbol rx× 1 dimension, wherein N rxrepresent reception antenna number) oneself signal can be expressed as interference signal with noise n (k, l) three part and:
r ( k , l ) = H &OverBar; 1 ( k , l ) d 1 ( k , l ) + &Sigma; j = 2 H &OverBar; j ( k , l ) d j ( k , l ) + n ( k , l )
Wherein, d j(k, l) and represent that between jGe community and target terminal, transmission signal vector and N are tieed up in r × 1 respectively tx× r ties up equivalent channel matrix, wherein N txrepresent number of transmit antennas, r represents the transmission number of plies. wherein H j(k, l) is N rx× N txdimension channel matrix, P j(k, l) is N tx× r ties up pre-coding matrix.The estimated signal of UE end for r × 1 is tieed up, by r × N rxthe reception weights W of dimension rX, 1(k, l) obtains:
d ^ 1 ( k , l ) = W RX , 1 ( k , l ) r ( k , l )
For senior receiver MMSE-IRC receiver, receiving weights is:
W RX , 1 ( k , l ) = H &OverBar; ^ 1 H ( k , l ) R - 1 , R = P 1 H &OverBar; ^ 1 ( k , l ) H &OverBar; ^ 1 H ( k , l ) + &Sigma; j = 2 H &OverBar; ^ j ( k , l ) H &OverBar; ^ j H ( k , l ) + &sigma; 2 I
Wherein, for the equivalent channel matrix of interference signal estimated.
Or, when being unable to estimate the equivalent channel matrix of interference signal, estimate covariance matrix R can be carried out based on the signal power receiving interference plus noise,
R = P 1 H &OverBar; ^ 1 ( k , l ) H &OverBar; ^ 1 H ( k , l ) + 1 N sp &Sigma; k , l &Element; IMR _ NAIC r ~ ( k , l ) r ~ ( k , l ) H
Wherein, IMR_NAIC is the resource for interferometry, N spfor the number of samples for interferometry resource.
Pertinent literature/technology has proved to use MMSE-IRC receiver relative to traditional MRC or MMSE, demodulation performance all has a more substantial increase, and its reason is just that MMSE-IRC receiver can utilize the received signal power of interference channel covariance matrix or interference plus noise to obtain and receive weights more accurately.Therefore, know that interferometry information is more accurately in MMSE-IRC or the effective way more improving receptivity in senior receiver situation further.
