Description
Technical field
The invention belongs to wireless communication technology field, more particularly, to a kind of communication means of multi-standard heterogeneous system, user
Equipment and base station.
Background technology
With the development of radio network technique, existing 2G (GSM/CDMA)/3G (UMTS/CDMA2000/TDS-CDMA/
WiMAX) will be progressively by with Long Term Evolution（Long Time Evolution, LTE）/ Long Term Evolution strengthens（Long Time
Evolution Advanced, LTE-A）4G technology by representing is replaced.And this process will be the process of individual progressively evolution,
User can progressively move on 4G network, and 2G/3G user will be coexisted with 4G user for a long period of time, at this moment, for operator
For it may appear that such situation：The frequency spectrum of 2G/3G carries a small amount of user, and the frequency spectrum of 4G become very crowded it is contemplated that
Operator, in order to obtain these frequency spectrum resources, spends great amount of cost, this phenomenon for operator be one very serious
Problem.
In order to improve peak rate and the availability of frequency spectrum, LTE-A starts to introduce heterogeneous network technologies from Rel-10.Isomery
Network refers to low power nodes（Low Power Node, LPN）It is placed in macro base station coverage area by cloth, formed with covering not
With the different heterogeneous system of node type.User equipment due to access point and being serviced（User Equipment, UE）Between
Geographic distance reduced, being capable of effectively lift system handling capacity and network whole efficiency.Macro base station coverage is by former
Come single subdistrict, split into some Microcells due to laying some LPN, same frequency range is re-used several times, system can obtain
Obtain huge cell splitting gain, but because the coverage of LPN is completely in the coverage of macro base station, thus can go out
Existing substantial amounts of edge customer, how to solve macro base station becomes to the interference of LPN cell that current LTE-A isomery network technology is main to be examined
The problem considered.
Pass through in existing LTE R10 to introduce approximate blank subframe in macro base station（Almost Blank Subframe,
ABS）To solve this problem, in these approximate blank subframe, macro base station will not send data, so, Microcell is corresponding to
The interference that subframe on position is subject to will be very little, and Microcell is possible to be in for it in the subframe of these interference coordinations little
The UE of area edge provides service.
Although prior art can reduce and reduce UE serviced to Microcell on the specific running time-frequency resource of macro base station and do
Disturb, but yet suffer from two problems.
Problem one：Prior art can only partly reduce the interference of macro base station UE serviced to Microcell, even if specific
In blank resource, because macro base station still can be in these transmitted on resources cell specific reference signal（Cell-specific
Reference Signals, CRS）, the interference of therefore macro base station UE serviced to Microcell can not be completely eliminated, especially when
Expanded using coverage（Range Expansion, RE）After technology, the UE that some belonged to macro base station service originally is migrated to
In LPN cell, at this moment, the interference from the CRS of macro base station will be a problem that cannot avoid.
Problem two：In a real system, portfolio is time-varying, as the activation UE not needing service under macro base station
When, macro base station will not launch data, and optimal situation is that at this moment macro base station is exactly in ABS subframe, and work as and have activation UE
When, macro base station is in non-ABS subframe, and because ABS sub-frame configuration is semi-static, can not meet real-time requirement, because
The UE of this macro base station regardless of when need service it is necessary to wait until service could be obtained in non-ABS subframe, this will affect this
The performance of a little UE.
In sum, prior art can not be completely eliminated the interference of macro base station UE serviced to LPN, or grand in order to eliminate
The interference of base station, the performance that will sacrifice macro base station UE is cost.
