Description
Technical field
The present invention relates to the communications field, in particular to a kind of sending method for measuring pilot tone, channel condition information
Feedback method and device.
Background technology
Multiple-input and multiple-output (multiple-input-multiple-output, referred to as MIMO) is wireless communication field
In one of important technology.It includes space diversity and space multiplexing technique, and the former can improve the reliable of wireless communication link
Property, and the latter can improve the spectrum efficiency of wireless communication system.But higher performance is obtained, it is necessary to which transmitting terminal is being sent
During data, it is known that channel condition information during wireless communication transmissions.But wireless channel is generally among constantly change, in order to
The change of channel is can adapt to, in Long Term Evolution (Long Term Evolution, referred to as LTE) system, user equipment
(User Equipment, referred to as UE) can pass through down physical channel status information (Channel State
Information, referred to as CSI) downlink channel quality information reported into base station.Reflect down physical channel CSI's in LTE
Feedback content includes following three：
(1) channel quality instruction (Channels quality indication, referred to as CQI)；
(2) pre-coding matrix instruction (Pre-coding Matrix Indicator, referred to as PMI)；
(3) order instruction (Rank Indicator, referred to as RI)；
Wherein, RI be responsible for indicate channel matrix order, i.e. can parallel transmission the data number of plies；PMI is responsible for UE and provides hair
Send the suggestion of precoding；CQI is Signal to Interference plus Noise Ratio (Signal to when UE transmits to the RI and PMI that are fed back by it
Interference plus Noise Ratio, referred to as SINR) horizontal estimated, it is responsible for assistant base station determining modulation and coding
Tactful (Modulation Coding Scheme, referred to as MCS).The content of CSI feedback is typically in certain reference signal
Measure and be calculated on (Reference Signal, referred to as RS), wherein, RS can include but is not limited to below at least
One of：
(1) cell specific reference channel (Cell Specific Reference Signal, referred to as CRS)；
(2) channel state information reference signals (Channel State Information Reference Signal, letter
Referred to as CSI-RS)；
(3) interferometry resource (Interference Measurement Resource, referred to as IMR).
LTE uses orthogonal frequency division multiplexi (Orthogonal Frequency Division in cell
Multiplexing, referred to as OFDM) technology, intra-cell users signal in orthogonal, its interference can be controlled preferably.And phase
The frequency duplex factor as one of adjacent cell is 1, i.e., usually using identical frequency between neighbor cell, therefore, inter-cell interference is very tight
Weight, or even serious inter-cell interference cause cell-edge performance poor, and this is a major issue of LTE system.
In order to improve the performance of Cell Edge User, long-term evolution upgrading (Long Term Evolution-
Advanced, referred to as LTE-A) system introduce coordinate multipoint (Coordinated Multi-Point, referred to as CoMP) biography
Transferring technology, CoMP technologies reduce the interference of Cell Edge User by multiple adjacent base stations or node cooperation, so as to improve
Its service quality.CoMP technologies are broadly divided into following three kinds：
(1) joint transmission (Joint Transmission, referred to as JT)；
In JT, when multiple cooperation cells are providing signal transmission for targeted customer jointly on identical running time-frequency resource,
For terminal, interference signal can be changed into useful signal, so as to greatly improve the quality of reception of signal.Further, JT
Two kinds of relevant JT (Coherent JT) and incoherent JT (Non-coherent JT) can be divided into again.Relevant JT needs UE to feed back
Phase difference between different transmission nodes (Transmission Point, referred to as TP), to ensure different TP signal at UE
Can be with addition；The base band data of transmission needs to contribute in different TP, to realize combined coding.Because it is wanted to feedback and backhaul
Ask higher, and performance gain is limited, current agreement wouldn't be supported.In incoherent JT, different TP can transmit independent
Data are to UE, without combined coding, because its requirement to backhaul is relatively low, so it is more practical.
(2) dynamic node selection/dynamic node eliminates (Dynamic point selection/Dynamic point
Blanking, referred to as DPS/DPB)；
(3) cooperative scheduling cooperative beam figuration (Coordinated Scheduling Coordinated
Beamforming, referred to as CSCB)；
DPS can be serviced to optimize the service quality of user by the optimal cell of dynamic select channel condition, and
CSCB and DPB then can suppress the interference to targeted customer by the scheduling or transmission control of cooperation cell.
In the 5th third-generation mobile communication technology (5G), dense deployment transmission node meets that growing traffic demand will
As a universal trend.Distance between TP only has tens meters even more than ten meters.Intensive transmission section can provide high division
Gain, meet the capacity requirement of the hot zones such as downtown area, Office Area, but also bring even more serious interference problem simultaneously, therefore
And CoMP technologies also more seem necessary.At the same time, the transmission node of dense deployment also introduces new scene for CoMP technologies.
TP quantity is big in dense network, and single TP cost must reduce, so simple in construction, antenna number turns into TP change compared with major general
Trend.Meanwhile it is in small distance between TP and UE, signal propagation path is possible for direct projection footpath.Under the environment that multipath does not enrich
It is generally difficult to UE while sends multiple data flows, and with UE development, more antennas of equipment turn into trend, and UE antenna is certainly
Cannot sufficiently it be utilized by degree.At this point it is possible to by JT, a part of data flow respectively is sent for UE by two TP, so as to realize
Multilayer transmission.Meanwhile DPS/DPB under dense network and CS/CB also require more flexible interferometry, to support these skills
Art.
In general, the main interference of user is from adjacent several cells.Existing LTE technologies can only be disturbed by CSI
Measurement (CSI-interference measurement, referred to as CSI-IM) is disturbed to measure, and what CSI-IM may be measured
It is the channel in the data of adjacent area corresponding to possibility on channel.Corresponding to each CSI-IM on port, measurement is all interference
The signal of the superposition of all transmission antennas of base station, so what is in general measured is the statistical information of interference.It can not obtain
The accurate channel information of main interference base station, so as to can not accurately obtain channel condition information, for example obtains accurate CQI
Value and the more accurately information such as pre-coding matrix is selected according to CQI value.
