Description

The acquisition methods and system of interference relationships

Technical field

The present invention relates to the communications fields, in particular to the acquisition methods and system of a kind of interference relationships.

Background technology

Macrocell, which combines deployment composition layered coverage with Microcell, can improve the throughput of system of wireless access network, in order to Between macrocell and Microcell share frequency spectrum, a large amount of methods have been produced in academia and engineering, for example, Microcell with Identical frequency is used between macrocell in a time multiplexed way, this method of frequency spectrum of sharing in a time multiplexed way is in 3GPP There is discussion inside normal structure, and has been referred to as enhanced interference coordination(FeICIC)Technology.

With wave beam forming(beamforming)The gradually application of technology in a wireless communication system, in particular with having Source array antenna(AAS)The development of experimental research of the technology in cellular network base stations, how using shaped-beam technology Reusespectrum between the Microcell that macrocell and macrocell are covered has following possible realization method:

1)Using shaped-beam(Using the wave beam of beamforming technique)Macrocell and Microcell between using existing Time division multiplexing mode, that is, allow Microcell sent in the time slot that macrocell does not send business datum picocell traffic letter Number, for example use enhanced interference coordination(FeICIC)Technology;

2)Microcell except the main beam using the macrocell of shaped-beam, uses space division multiplexing between macrocell The mode of frequency is also located in the Microcell except macrocell main beam and uses the frequency transmission of main beam small at least partly Area's service signal;

3)It is multiple using the existing time-division between macrocell and Microcell in the main beam using the macrocell of shaped-beam With the mode of frequency;And except main beam, between macrocell and Microcell by the way of space division multiplexing frequency, also it is located in Microcell except macrocell main beam uses the frequency of main beam to send picocell traffic signal at least partly;

A kind of be used for by channel distribution layered portion reuse resource, to enhance telecommunications system is disclosed in the related art The cellular telecommunication method and system of the spectrum efficiency of system:Multiple available channels (110) in cell (15) are divided into logical groups (115,125), wherein each sharing identical radio resource (105).The system utilizes multiple technologies, and such as interference diversity is done It disturbs inhibition and/or interference avoids to reduce or eliminate interference.Such utilization of resource will create frequency spectrum active block in system Or cell (15) and can use less than one reuse.This method is used to increase the spectrum efficiency of radio system, specifically Include the following steps:Multiple channels in the cell of the radio system are divided into multiple logical groups;It is patrolled the multiple Collect first group of more than first a radio resource being mapped to for the cell among group;With among the multiple logical groups At least one other group of more than second a radio resources being mapped to for the cell, wherein the money of a radio more than described second At least one of at least one of source radio resource and more than described first a radio resources radio resource is identical.It is described Each logical groups among multiple logical groups have different frequency-hopping sequences;Each logical groups tool among the multiple logical groups There is different training sequences;Each logical groups among different directions send the multiple logical groups;A nothing more than described first Line electric resources and more than second a radio resources are identical;It is described in the technology through the wave beam feature of adaptive antenna come real Existing interference and insulation realizes the shared of resource by frequency hopping, by sending the identical wave beam of two frequencies come spatial reuse frequency Method, these methods have been known technologies in the industry.

A kind of resource allocation methods for hierarchical cellular system are also described in the related art and execute this method Transmission frame.The utilization rate of utilization rate and shared resource based on macrocell private resource come control respectively macrocell private resource and Shared resource.Macrocell reports the application plan for the shared resource that macrocell uses to small cell(That is Microcell), small Shared resource can be distributed to terminal by cell based on the application plan of shared resource.It can be via transmission frame transmission/reception and use Plan relevant control message.Including:In macrocell using before shared resource, by the application plan of shared resource report to Resource is distributed to the terminal of its service, and this use meter of the distribution based on shared resource by small cell, small cell It draws;Small cell identifies the resource not used by macrocell based on the application plan of shared resource, the resource that will identify that Distribute to the terminal of small cell serves;It is assigned to by small cell serves by the resource that macrocell uses in shared resource Terminal, and macrocell and small cell use power control scheme, interfere at least one in control program and multiple antennas scheme It is a to be interfered with controlling;Macrocell is reported the application plan of shared resource to small cell with the interval subscribed;Macrocell very little Cell can use identical resource.Further, which discloses a kind of device, including:Transmission frame includes to have The control area of the control information of shared resource application plan, macrocell use the control information by the use meter of shared resource Report is drawn to small cell;Specifically, small cell can identify macrocell to shared money using the control information of macrocell The application plan in source.The technology discloses Microcell and determines the money of Microcell to the service condition of shared resource according to macrocell The method in source, therefore, the method that macrocell sends its resource application plan to Microcell have been the prior arts.For multiple antennas Transmission plan, the technology also disclose that the occupation mode to beamforming function:Using suitable beam forming matrix or with Encoder matrix executes Wave beam forming, and each destination node can extract the desired signal for only having and interfering on a small quantity, also, mesh Node can execute receive Wave beam forming and/or use space filtering come reduce interference.

Above-mentioned background technology shows for smart antenna/phased array antenna, does multi-beam transmission in different directions It is known technology, Microcell(Small cell)The macrocell sent according to macrocell is small to the application plan of shared resource The terminal configuration resource of area's service is known technology, and destination node receives signal and/or use space transmitted by Wave beam forming It filters to reduce interference and known technology.

But cover the different geographic regions in a macrocell dynamically changing beam position using shaped-beam When, the secondary lobe of shaped-beam, main lobe and multipath component can dynamically change with the change of beam position, be located at shaped-beam The intensity of the interference from macrocell shaped-beam suffered by the same Microcell except main lobe also can be with shaped-beam Be directed toward different and dynamically change, in addition, the angle between the antenna direction and shaped-beam of Microcell wireless access point with Machine variation is also to cause interference with the factor of intensity randomization, therefore, empty between Microcell and macrocell shaped-beam in order to ensure The reliability of frequency of use, Microcell is divided to need this dynamic disturbance information to Microcell using macrocell shaped-beam.So And Microcell cannot obtain this information in the application plan from the macrocell that macrocell is sent to shared resource, the relevant technologies In also do not provide and obtain macrocell shaped-beam to the method for the interference information of Microcell.

The problem of for interference information of the macrocell shaped-beam to Microcell can not be obtained in the related technology, at present not yet It is proposed effective solution scheme.
