Abstract
The invention discloses a kind of dense network capacity boost method decoupled based on frequency division multiplexing and up-downgoing.In dense network, the interference ratio between base station is more serious, requires higher place for up-downgoing flux density, and user accesses different base stations when uploading and download data.There is presence of intercell interference for Cell Edge User, it cannot be guaranteed that rational user performance under the scene of severe load, edge user throughput can degradation.Use partial frequency multiplexing method suppression presence of intercell interference.In the invention, base station is respectively adopted the part frequency-division multiplexing method that frequency duplex factor as one is 3 and frequency duplex factor as one is 1, data transmission up-downgoing decoupling between user and base station simultaneously.The ingenious combination of frequency division multiplexing and up-downgoing decoupling method effectively inhibits presence of intercell interference, makes whole network throughput be optimized, thus improves the capacity of system in dense network.The present invention has important practical significance and good application prospect.
Description
Technical field
The present invention relates to mobile communication technology field, in particular to a kind of based on frequency division multiplexing with upper in 5G system
The dense network capacity boost method of descending decoupling.
Background technology
In following 5G communication system, cordless communication network is just towards network multi-element, broadband, synthesization, intelligence
The direction evolution changed.Along with popularizing of various intelligent terminal, data traffic will appear from the growth of blowout formula.Future Data business will
Being mainly distributed on indoor and hot zones, this makes super-intensive network become 1000 times of traffic demands main realizing following 5G
One of means.Super-intensive network UDN is one of core technology of 5G, by the Scaledeployment of WAP, can significantly drop
The distance that low user accesses, thus improve the handling capacity of user and the handling capacity (bps/km in region2), it is to meet 5G system to hold
The key technology of amount demand.Super-intensive network can improve the network coverage, significantly promotes power system capacity, and carries out business
Shunting, has more flexible network design and more efficient channeling.In future, towards the big bandwidth of high band, will use more
Intensive network plan, disposes small-cell/sector and will be up to more than 100.
Meanwhile, the most intensive network design also makes network topology more complicated, and presence of intercell interference has become as
The principal element that system for restricting capacity increases, significantly reduces network energy efficiency.
For problem of inter-cell interference, due between neighbor cell band overlapping and the presence of intercell interference that produces is system
Subject matter, can cause serious loss to systematic function especially community marginal user performance.For interference coordination, employing portion
Divide frequency multiplexing technique, available band will be divided into 3 sub-bands, when frequency is distributed, Cell Center User and edge are used
Family is distinguished and is treated, the allocated less proportional band of edge customer, and son frequency allocated between the edge customer of neighbor cell
Band mutually disjoints.Assume that frequency duplex factor as one is k, then each sub-band can be re-used in every k minizone.If mobile terminal
Channel is good, then use relatively low frequency duplex factor as one, if channel condition is severe, then uses higher frequency duplex factor as one.FFR
Systematic function optimization will be made to each terminal distribution most suitable frequency band k.
In terms of base station deployment, for wireless small station, owing to its main purpose is to meet the demand that high flow capacity covers,
The access link in small station is generally of higher data transmission capabilities, and the wireless backhaul links in the most wireless small station also should be supported
High speed data transfer, to reach the high-performance of entirety.Radio node accesses the mode of macro base station, exists in super-intensive networking scene
Certain problem: first, macro station is usually the work of low frequency provides wide area to cover, and macro station bandwidth will not be very big, can not meet height
The return link transmission of speed needs；Secondly, even if macro station supports the working frequency points of the big bandwidth of high frequency, but due to high band situation
Under, wavelength is short, loss is fast, and penetration capacity is poor, substantially etc. various former by the occlusion effect of building, leaves and human body
Cause, compares traditional low-frequency section cellular system, there is substantial amounts of covering shade, also cannot guarantee to provide stable for wireless small station
Two-forty upstream transmission services；Owing to the descending covering power of dissimilar base station is different, it is provided that best up covering performance
Base station best descending covering might not be provided.Such as when user is near micro-base station, access micro-base station and be obtained in that more
Good ascending performance.And owing to the transmitting power of macro base station is much larger than micro-base station, user access macro base station can obtain more preferable under
Row performance.It can be seen that up-downgoing accesses different base station, part work is being had to relate to this respect in 5G communication network at present
Content, is referred to as up-downgoing decoupling.Lower powered little base station is more and more intensive, it is provided that the base station of optimum up covering performance is sometimes
Time can not provide optimum descending covering.Therefore user's up-downgoing need not access same base station.I.e. up-downgoing decoupling, inhomogeneity
Load balancing between type base station, maximization network handling capacity.
