Description

A kind of wave beam forming training method, terminal and base station
Technical field
The present invention relates to communication technical field, more particularly to a kind of wave beam forming training method, terminal and base station.
Background technology
In view of MIMO (Multiple-Input Multiple-Output, enters to have more) technology for improving peak rate more With the important function of system spectrum utilization rate, LTE (Long Term Evolution, Long Term Evolution)/LTE-A (LTE- ) etc. Advanced wireless access technology standard is all with MIMO+OFDM (Orthogonal Frequency Division Multiplexing, OFDM) construct based on technology.The performance gain of MIMO technology comes from multiple antennas System can be obtained spatial degrees of freedom, therefore a most important evolution tendency of the MIMO technology during Standardization Development It is the extension of dimension.In LTERel-8,4 layers of MIMO transmission can be at most supported.Rel-9 emphasis is to MU-MIMO technologies Strengthened, (Multi-User MIMO, multi-user are more by TM (Transmission Mode, transmission mode) -8 MU-MIMO Enter to have more) transmission in can at most support 4 downlink data layers.Rel-10 then passes through 8 port CSI-RS (Channel State Information Reference Signal, channel state information reference signals), URS (UE-specific Reference Signal, UE specific reference signals) spatial discrimination of channel condition information is further increased with the introducing of multi-granule code book Rate, and SU-MIMO (Single-User MIMO, single user are entered to have more more) transmittability is further extended to most 8 Data Layer.
In base station antenna system using traditional PAS (Passive Antenna System, passive antenna system) structure, Multiple antenna ports (each port correspond to independent radio frequency-intermediate frequency-Baseband Channel) are horizontally arranged, and corresponding to each port Connected between multiple a period of time of vertical dimension by radio-frequency cable.Therefore existing MIMO technology can only be in level dimension by different ends Mouthful between relative amplitude/phase adjustment realize to each terminal signaling horizontal dimension space characteristic optimization, in vertical dimension then Unified sector-level figuration can only be used.AAS (Active Antenna System, active antenna are introduced in GSM System) after technology, base station antenna system can obtain the bigger free degree in vertical dimension, can be realized in three dimensions to UE The signal optimization of (User Equipment, user terminal) level.
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 carrying out FD-MIMO (Full Dimension MIMO, Full dimension MIMO) technical research and standardization effort.And then more prediction ground has been carried out for being based on more extensive day for academia The research and test job of the MIMO technology of linear array.Academic research shows with preliminary channel measured result, Massive MIMO (extensive 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 in next generation mobile communication system by major research tissue One of technology.
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 (multi-user's multiple-input, multiple-output) performance, but this structure needs substantial amounts of AD/DA (digital-to-analogue/modulus) transition period and a large amount of complete radio frequencies-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 Massive The cost of implementation of MIMO technology and equipment complexity, in recent years it has been proposed that using numerical model analysis beamforming technique.So-called number Mould mixed-beam figuration (see Figure 11), refer on the basis of traditional numeric field wave beam forming, close to antenna system front end, Increase one-level simulation figuration in radiofrequency signal.Simulation figuration can make transmission signal and channel by relatively simple mode Realize more rough matching.The dimension of the equivalent channel formed after simulation figuration is less than actual antenna amount, therefore thereafter Required ad/da converter part, digital channel number and corresponding Base-Band Processing complexity can be greatly lowered.Simulate figuration The interference of portion of residual can carry out single treatment again in numeric field, so as to ensure the quality of MU-MIMO transmission.In Figure 11, K Data flow (S1(t)……SK(t)) it is mapped in M digital channel (Transceiver), passes through by digital beam forming (DBF) Cross digital-to-analogue conversion (DAC) and then be mapped to Nt transmitting antenna (Antenna) up by simulation figuration (ABF).
For digital figuration, numerical model analysis wave beam forming is a kind of half-way house of performance and complexity, There is higher practical prospect in the big bandwidth of high band or the very big system of antenna amount.
In MIMO technology, especially for MU-MIMO (multi-user's multiple-input, multiple-output) technology, letter that network side can obtain Channel state information precision will directly determine the precision of precoding/wave beam forming and the efficiency of dispatching algorithm, so as to have influence on entirety Systematic function.Therefore, one of the problem of acquisition of channel condition information is always most crucial in MIMO technology standardization.
According to current LTE signal structures, because reference signal all assigns into base band, therefore can be estimated by channel Meter obtains the channel status needed for digital figuration.But because the digital equivalent port number that simulation figuration is formed is less than actual day Line number, the complete channel matrix undergone by reference to the dimension of the channel matrix of signal acquisition well below antenna end Dimension.Therefore, digital figuration can be obtained spatial resolution and interference rejection capability receives certain loss.For mould For intending figuration part, its processing procedure is closer to physical antenna side, and for digital figuration, its mimo channel has The higher free degree.However, the reference signal of base band insertion is estimated due to having no idea, thus no matter to FDD (frequency divisions Duplex) or TDD (time division duplex), it simulates the channel condition information that figuration part directly can not all be obtained using numeric field.
Therefore, it is however generally that in numerical model analysis beam-forming system, the selection to analog beam can only typically pass through search The mode of (or training) is carried 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.When channel condition changes and (such as blocked), it is System will reenter the beam search stage, it is necessary to carry out traversal search to potential transmitting-receiving beam combination.
When uplink beam training process is completed, base station side (eNB or TRP) is it needs to be determined that the optimal up transmitted wave of end side Beam, and the up launching beam that base station is selected informs terminal.So terminal is in uplink, it is possible to up using this Wave beam is transmitted.In existing scheme, the launching beam number that terminal is supported is usually fixed, therefore can be in advance to such One group of wave beam is numbered.After the completion of uplink beam training, base station side can to terminal notification, it be recommended by Downlink Control Information Up launching beam corresponding to numbering.
In existing way, the wave beam Limited Number supported terminal is determined, can not be according to terminal capability and specific applied field The number of beams used during training is adjusted flexibly in scape.
