Description

A kind of information transferring method and relevant device
Technical field
The present invention relates to field of communication technology, more particularly to a kind of information transferring method and relevant device.
Background technology
In view of multiple-input and multiple-output (Multiple-Input Multiple-Output, MIMO) technology is for improving peak value The important function of speed and system spectrum utilization rate, Long Term Evolution (Long Term Evolution, LTE)/advanced are drilled for a long time All it is with MIMO+ Orthogonal Frequency Division Multiplexing (Orthogonal into the wireless access technology such as (LTE-Advanced, LTE-A) standard Frequency Division Multiplexing, OFDM) construct based on technology.
The performance gain of MIMO technology comes from multiaerial system and can be obtained spatial degrees of freedom, therefore MIMO technology exists A most important evolution tendency during Standardization Development is the extension of dimension.In LTE Rel-8, it can at most prop up Hold 4 layers of MIMO transmission.Rel-9 emphasis strengthens multiuser MIMO (Multi-User MIMO, MU-MIMO) technology, 4 downlink data layers can be at most supported in the MU-MIMO transmission of transmission mode (Transmission Mode, TM) -8.Rel- 10 pass through 8 port channel state information reference signals (Channel State Information-Reference Signals, CSI-RS), the specific reference signal of mobile station (UE-specific Reference Signal, URS) with more The introducing of granularity code book further increases the spatial resolution of channel condition information, and further by Single User MIMO The transmittability of (Single-User MIMO, SU-MIMO) extends to most 8 data Layers.
In base station antenna system using traditional passive antenna system (Passive Antenna System, PAS) structure, Mutiple antennas port levels arrange, and each port corresponds to independent radio frequency-intermediate frequency-Baseband Channel, and each port is corresponding vertical Connected between the multiple a period of time directly tieed up by radio-frequency cable.Therefore existing MIMO technology can only be in level dimension by different port Between relative amplitude and/or phase adjustment realize to each terminal (User Equipment, UE) signal in horizontal dimension space The optimization of characteristic, unified sector-level figuration can only be then used in vertical dimension.Active antenna system is introduced in mobile communication system After (Active Antenna System, AAS) technology, base station antenna system can obtain the free degree of bigger in vertical dimension, It can be realized in three dimensions and the signal of terminating stage is optimized.
On the studies above, standardization and antenna technology development foundation, industrial circle is further by MIMO technology Promoted towards the direction of three dimensional stress and large-scale.At present, 3GPP is carrying out full dimension MIMO (Full Dimension MIMO, FD-MIMO) technical research and standardization effort.And then more prediction ground has been carried out for based on more extensive for academia The research and test job of the MIMO technology of aerial array.Academic research and preliminary channel the result of actual measurement shows that, on a large scale (Massive) MIMO technology can greatly lifting system band utilization efficiency, support greater amount of accessing user.Therefore Massive MIMO technologies are considered as most potential physical-layer techniques in next generation mobile communication system by major research tissue One of.
Massive MIMO technologies need to use large-scale antenna array.Maximum can be realized although with total word array The spatial resolution of change and optimal MU-MIMO performances, but this structure needs substantial amounts of ad/da converter part and a large amount of Complete radio frequency-Base-Band Processing passage, either equipment cost or Base-Band Processing complexity all will be huge burden.This Problem seems especially prominent in high band, big bandwidth.
In order to reduce the cost of implementation of Massive MIMO technologies and equipment complexity, in recent years it has been proposed that using digital-to-analogue Mixed-beam figuration technology.So-called numerical model analysis wave beam forming, refers on the basis of traditional numeric field wave beam forming, close The front end of antenna system, increases level-one analog beam figuration in radiofrequency signal.Analog beam figuration can be by relatively simple Mode, transmission signal and channel is realized more rough matching.The dimension of the equivalent channel formed after analog beam figuration Less than actual antenna amount, therefore ad/da converter part needed for after analog beam figuration, digital channel number and corresponding Base-Band Processing complexity is all greatly lowered.The interference of analog beam figuration portion of residual can once be located again in numeric field Reason, so as to ensure the quality of MU-MIMO transmission.
For digital wave beam forming, numerical model analysis wave beam forming is a kind of compromise side of performance and complexity Case, has higher practical prospect in the very big system of the big bandwidth of high band or antenna amount.
In MIMO technology, especially for MU-MIMO technologies, the channel condition information precision that network side can obtain will The precision of precoding/wave beam forming and the performance of dispatching algorithm are directly determined, so as to influence overall system performance.Therefore, believe One of the problem of acquisition of channel state information is always most crucial in MIMO technology standardization.
According to current LTE signal structures, reference signal all assigns into base band, therefore can be by baseband signal The channel estimation of middle reference signal obtains the channel status needed for digital beam forming.But since analog beam figuration is formed Digital equivalent port number be less than actual antennas number, by reference to signal obtain channel matrix dimension well below day The dimension for the complete channel matrix that line end is undergone.Therefore, digital beam forming can be obtained spatial resolution and interference Rejection ability receives certain loss.The processing procedure of analog beam figuration part is closer to physical antenna side, digital wave The mimo channel of beam figuration has the free degree of higher.However, the reference signal of base band insertion is estimated due to having no idea Meter, because regardless of whether to frequency division duplex (FrequencyDivisionDuplex, FDD) or time division duplex (TimeDivisionDuplex, TDD), the channel status letter that analog beam figuration part all can not directly be obtained using numeric field Breath.
Therefore, it is however generally that in numerical model analysis beam-forming system, the selection to analog beam can only generally pass through search The mode of (or training) carries out.In this course, transmitting terminal launches one group of wave beam, and receiving terminal also uses one group of predetermined ripple Reception exploratory Shu Jinhang, to judge optimal transmitting-receiving beam combination.Which changes slow field for communication environments Scape is more applicable in, but in the higher frequency range of frequency, there are many uncertain factors for the communication process of signal.Wherein blocking effect The problem of being more special in high band communication.Specifically, with during the rise Radio Signal Propagation of frequency range, energy is most Radius for the Fresnel region of concentration can be gradually reduced.Therefore some very common objects in communication environments, such as vehicle, people Body, column etc. can produce high band communication strong influence, even result in communication disruption.
Based on existing beam search and follow-up mechanism, when stopping generation, system will reenter the beam search stage, Need to carry out traversal search to potentially large number of transmitting-receiving beam combination, it will consume a large amount of system resources, cause larger system to prolong Late, hence it is evident that reduce system effectiveness.
