Description
Technical field
The invention belongs to the resource regulating methods and dress in field of communication technology more particularly to a kind of cordless communication network
It sets.
Background technique
Under wireless communication network environments, an important factor for interference is system for restricting capacity, currently, leading in mobile communication system
Interference is reduced or eliminated frequently with interference coordination technique.Interference coordination technique needs to carry out cell in advance resource distribution, distribution
Exclusive resource block to a cell is preparatory static configuration, and in order to realize interference coordination, the time of each cell of system requirements
It is synchronous.
In long term evolution (Long Term Evolution, LTE) system as shown in Figure 1, frequency resource block A (RB A)
Cell BS0 is distributed to, frequency resource block B (RB B) distributes to cell BS1；Frequency resource block A, frequency resource block B are supplied respectively
User equipment (User Equipment, UE) in BS0, BS1 positioned at cell edge position uses, positioned at center of housing estate position
Shared resource can be used in UE.
Existing interference coordination technique applies in general to the mobile communication system pre-planned such as mobile cellular network
In system, radio resource used in each base station is configured by the network planning and optimization, to ensure that interference coordination schemes
Feasibility.But it is existing in the communication network that WLAN and Home eNodeB etc. no longer plan deployment in advance by operator
Interference coordination technique then no longer be applicable in.
And most of communication networks such as WLAN and Home eNodeB are deployed in indoor environment, global positioning system
(Global Positioning System, GPS) signal is not easy to obtain, therefore time synchronization ratio is realized between each access point
It is more difficult, and in the case where no time synchronization, it works for time division duplex (Time Division Duplexing, TDD)
The WLAN of standard, such as handled up (NUHT) wireless communication system etc. using the WLAN of 802.11 agreements, superelevation,
And Home eNodeB, such as timesharing long term evolution (Time Division Long Term Evolution, TD-LTE) family's base
The phenomenon that stand (Femto) etc., interference at crossed slot between neighboring community influences also relatively more severe all than more serious.
The interference at crossed slot of minizone refer to two cells with frequency work under the premise of, two neighboring cell, wherein
The signal transmitting of one cell and the signal of receiving end in another cell receive there are it is temporal overlapping when, may be to another
The signal reception of receiving end causes strong jamming in a cell, and there may be following a variety of interference scenes for the interference of minizone.Such as:
The transmitting signal of the base station of user equipment or network side in one cell receives the signal of the user equipment in another cell
Interference.Another example is: in a cell base station of user equipment or network side transmitting signal, to base station in another cell
The received interference of signal.It is exemplified below and wherein interferes more serious two kinds of scenes:
Interference scene one is as shown in Fig. 2, cell A is in the downlink transfer period, and the base station BS 0 in cell A is to user
Equipment UE0 transmits data；Cell B is in uplink transmission cycle, and the base station BS 1 in cell B is receiving the transmission of user equipment (UE) 1
Data.If the user equipment (UE) 0 of downlink reception and the user equipment (UE) 1 of cell B uplink transmitting are relatively close apart in cell A, and
As shown in Figure 3, base station BS 0 distributes to the resource STA0 of user equipment (UE) 0 and base station BS 1 distributes to the money of user equipment (UE) 1
Source STA1 is overlapped in the presence of certain in time, and the user equipment (UE) 0 of that the one cell A downlink reception just will receive in cell B
The strong jamming for the signal that the user equipment (UE) 1 of row transmitting emits.
For interference scene two as shown in figure 4, cell A is in uplink transmission cycle, the base station BS 0 in cell A is receiving use
The data of family equipment UE0 transmission；Cell B is in the downlink transfer period, and the base station BS 1 in cell B is passed to user equipment (UE) 1
Transmission of data.Base station BS 0 in cell A will receive the strong jamming for the signal that the base station BS 1 in cell B emits when receiving signal.
In the mobile communication system pre-planned such as common mobile cellular network, since uplink and downlink emits function
Rate is asymmetric, and base station transmitting power is much larger than the transmission power of user equipment, and base station is typically deployed at higher geographical location,
Propagation conditions is preferable between base station, therefore the influence of interference scene two is even more serious.And in WLAN or family's base
It stands etc. and no longer to be planned in advance by operator in the communication network of deployment, since base station is identical as the transmission power of user equipment or connects
Closely, the power of interference signal is more related at a distance from interference source and receiving end, therefore interference scene is for a moment more severe.
As it can be seen that in the prior art, when neighboring community works with frequency in mobile communications network, when receiving end signal receives,
Inevitably there are the interference at crossed slot of signal.
