Description
Technical field
The present invention relates to relaying technique field more particularly to a kind of indoor minute surface void relaying distribution methods and device.
Background technology
With the extensive use of forth generation mobile communication system (4G), more and more researchers, operator, equipment vendor
Positive regard and (5G) development for pushing the 5th third-generation mobile communication.5G is communicated for the purpose of the transmission rate for realizing Gbps, substantially
It is required that being to realize that low time delay is highly reliable.The major technique that 5G is related to includes millimeter wave, extensive MIMO, beam forming etc..Have
It is the fundamental means of realization 5G high-speed transfers that effect, which utilizes the frequency range (such as 60GHz) of bulk unauthorized in millimeter wave, and due to antenna
Size is directly proportional to electromagnetic wavelength, and short wavelength's characteristic of millimeter wave can effectively reduce antenna array size.Extensive MIMO
Under beam forming technique (beam forming technique is the combination of antenna technology and Digital Signal Processing, be used for phasing signal
Transmission receives.Usually, beam forming is divided into two class of analog domain beam forming and numeric field beam forming.) orientation can be generated
Gain compensates the high path loss during millimetre-wave attenuator, while reducing multi-path jamming and multi-user interference.Although the big rule of millimeter wave
Mould antenna and the development that beam forming technique is 5G bring major transformation, but the characteristic of millimeter wave diffraction, penetrability difference makes
Communication easily causes to interrupt because of blocking.It is blocked to fight, the relaying technique based on the extensive antenna array of millimeter wave is met the tendency of
And it gives birth to.
In gsm system, repeater (Repeater) is a kind of simple relaying technique, is simply possible to use in coverage area
It is promoted, there is no any contribution to cell capacity；In LTE-Advanced systems, relaying is one of core technology, main function
For：Expand the coverage area, improve handling capacity, mend it is blind.In wireless network, relay node introduces the processing to baseband signal, by
This relaying can be divided into amplification forwarding (AF, Amplify and Forward) relaying and decoding forwarding (DF, Decoding and
Forward it) relays.Traditional reception for relaying the selection, data that need complicated Signalling exchange to realize relaying and forwarding etc., together
When relay node the increase of Time Delay of Systems and the loss of throughput of system can be brought to the processing of baseband signal.As in network
The resource allocation of node, bandwidth, time-frequency, power of tradition relaying etc. is also a great problem.
It is relayed relative to tradition, void relaying (being mostly strong reflector) passes through strong reflector using frequency electromagnetic waves like photosensitiveness
Single order, second-order reflection provide alternate communication link for receiver.Void relaying overcomes the shortcomings that tradition relaying, but general reflection
Know from experience the absorption loss generated to signal more than or equal to 2dB.In different application scenarios, void relays the problem of how laying industry
Boundary there is no people to provide suitable solution.
