Referred to as UDN) just receive more and more attention.When existing LTE-A technology is applied to super-intensive network
In, the interference between each cell common reference signal is increasingly severe along with the increase of number of cells.In order to avoid this
Individual interference, it is frequently necessary to carry out the coordination switch of minizone, i.e. closes cell portion certain period in UDN
Interference is reduced in base station, and closes another part cell base station in another a period of time.In order to coordinate and reduce each little
The interference in district, it is possible to use preferably return link carrys out real-time interactive service flow information, and according to service traffics
Information carries out the centralized Control of each community switch.But, preferable return link considerably increases return network
Lower deployment cost, all being difficult under all covering scene in actual network design all realizes ideal passback.
Fig. 1 is the schematic diagram of super-intensive network breaker in middle mode of operation in correlation technique, as it is shown in figure 1, grand base
Covering of standing can provide large range of Radio Link support, but cause the quality of link farther out due to transmission range
Affected by certain；Each little base station provides more excellent Radio Link for terminal, for strengthening the appearance of network
Amount.But, the densification covered along with small-cell, the distribution of little base station more crypto set and unordered, slight interval
Interference become sufficiently complex, create more edge customer, seriously limit the whole of whole UDN network
Body handling capacity.In order to coordinate the interference between each community in the case of return link is nonideal, through frequently with
The interference coordination pattern (hereinafter referred to as pattern switching mode) of community switch, the most each community is carried out by pattern
Carry out the switch of cell signal according to certain pattern, thus reduce the interference between each community.The right side of Fig. 1

Community can determine the on off state of oneself according to pattern.Concrete switch pattern can be by unified point of Centroid
Join, it is also possible to produced through consultation according to the disturbance regime detected by each community and its neighbor cell.In pattern
Carry out community switch unit interval section can from the radio frames of one 1 millisecond (ms) subframe to multiple 10ms,
The control duration (the most whole switch pattern cycle) of whole pattern depends on the physical length switching pattern, permissible
From several ms to tens, ms hundreds of, thousand of, the most longer.So, the related control information of each minizone
Can carry out according to the actual delay profiles of return link alternately, and produce corresponding length aperiodicity or
Periodically switch control rule pattern.
Although pattern switching mode can effectively carry out interference coordination in the case of return link is nonideal, but
Limit the peak rate of user the most to a certain extent.This is because community is in pass in a part of subframe section
Closing OFF state, user cannot utilize this part subframe to carry out data transmission.In order to overcome this shortcoming, can
To use multi-link data transfer scheme, i.e. user to set up multiple connection with adjacent multiple cell base stations simultaneously,
Different connections is used to carry out data transmission in the different switch unit interval.So, this user just can utilize
All subframes carry out data transmission, and substantially increase the peak rate of transmission.Further, each little due to UDN
District uses the channel of identical frequency, this multi-link communication mode to have only to just use a set of wireless device
It is achieved that do not increase the cost of user terminal, the alien frequencies dual link scheme that this and 3GPP discuss is the most not
With.But, it is concrete that the multi-link data transmission method discussed in the past does not consider under pattern switching mode
Implementation method.
