Description
Technical field
The present invention relates to a kind of technology for reducing presence of intercell interference, more particularly to a kind of inter-cell interference coordination method and dress
Put, network node.
Background technology
There is statistics to show, following 80%～90% throughput of system will occur in indoor and focus occasion.It is traditional at present
Honeycomb network technology there is weight outdoor light indoor, the light isolated hot spots of weight beehive net, weight mobile handoff gently to fix nomadic etc. spy
Point.One of focus of advanced long-term evolution system (LTE-Advanced, Long Term Evolution Advanced)
Exactly indoor and focus scene is optimized.Heterogeneous network (Heterogeneous Networks) is obviously improved as one kind
The technology of throughput of system and raising network whole efficiency, can meet the demand of LTE-Advanced well.Heterogeneous network
Structure has introduced some relative to the less transmitting node of traditional cell base station transmission power, including Pico cell
(Picocell), femtocell (Femtocells) and the relay station (Relay) for signal relay.These nodes draw
Enter guarantee well can be provided for the covering of indoor and focus occasion；Also, the transmission power of these nodes is little, it is easy to flexibly
Ground on-premise network；The coverage of these nodes is little simultaneously, can more easily utilize the potential high bands of LTE-Advanced
Frequency spectrum.But, the introducing of new node changes the topological structure of original network, becomes the presence of intercell interference of this network structure
One new challenge.
It is typically serious than homogenous networks (Homogeneous Network) in the interference of heterogeneous network medium and small interval, therefore need
Want the interference coordination technique of minizone to reduce the interference of minizone.Here, homogenous networks only have macro base station in being primarily referred to as network
The configuration scene of (eNB, Evoluted Node Base station) and user equipment (UE, User Equipment)；Isomery
Net is placed with the configuration scene of low power nodes (LPN, Low Power Node) in being primarily referred to as macrocell.Low power nodes bag
Long distance wireless dateline (RRH, Remote Radio Head) is included, for covering the femto base station (Pico eNB) of hot zones, family
Front yard base station (HeNB, Home eNB, alternatively referred to as femto), relaying (Relay node) etc..
At third generation partner program (3GPP, 3rd Generation Partnership Project)
In LTERAN162 meeting, it is determined that the mode coordinated using time domain is that part subframe is almost full empty frame (ABS, Almost
Blank Subffame) mode as solve heterogeneous network problem of inter-cell interference Main Means.According to RAN162 meeting
The conclusion of view, Target cell can obtain the subframe bitmap pattern (bitmap for disturbing adjacent area subframe to be that ABS and non-ABS is indicated
Pattern) information UE is passed to, therefore UE is known that each subframe of Serving cell is the ABS of correspondence strong jamming adjacent area
Or the non-ABS of strong jamming adjacent area.Almost full empty frame only sends public reference signal (CRS, Common only in this subframe
Reference Signal), do not send the subframe of other any signals.Strongly disturbing cell (aggressor cell) is produced
Middle to configure several descending sub frames for ABS, correspondence is by the Cell Edge User in strongly disturbing cell (victim cell)
Launch its descending control letter in (CEU, Cell Edge User) subframe only in the subframe of correspondence aggressor cell for ABS
Road and data channel.Cell Edge User in victim cell, can be subject to very strong presence of intercell interference, and due to being in clothes
Business cell edge causes signal power than relatively low, therefore is also victim UE.Cell Center User in victim cell (CCU,
Cell Center User) general transmitting down control channel and data channel in non-ABS subframes.When victim UE numbers
When fewer, when in victim cell, Cell Center User can also be ABS using remaining correspondence aggressor cell
Frequency resource.
In order to make UE and Serving cell obtain the synchronization of time and frequency in cell search process, and detect cell
ID, needs by synchronizing channel (SCH, Synchronization Channel), broadcast channel (BCH, Broadcast
) and downlink reference signal (RS, Reference Signal) is realizing Channel.Wherein, BCH is divided into main broadcast channel again
(PBCH, Primary BCH) and Dynamic Broadcast Channel (DBCH, Dynamic BCH).DBCH for broadcast system information is to hold
The system information block (SIB, System Information Block) being loaded in downlink shared transmission channel, its resource for taking
It is to be come according to the schedule information in Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel)
It is determined that.In addition, cell paging process needs by paging channel (PCH, Paging Channel) to realize.PCH is used to pass
Information Paging of defeated eNB pagings UE, the running time-frequency resource shared by which need to be believed according to the scheduling in PDCCH nor fixed
Cease to determine.
In order to realize the cell searching in radio communication and cell paging process, it is necessary to ensure the reliability of SIB/Paging
Transmission.To heterogeneous network, as victim cell and aggressor cell are common channels, i.e. its SIB/Paging and
Related PDCCH is transmitted on identical running time-frequency resource, thus in above-mentioned channel victim UE can by from
The strong interference of aggressor cell, and the signal power of cell edge is also than relatively low, so that it cannot correctly demodulating
Realize the signal of cell searching and cell paging.But in order to ensure cell searching and paging in aggressor cell,
The resource that SIB/Paging and correlation PDCCH can not be transmitted again is mourned in silence completely, is thus determined in RAN163 meeting
Still SIB/Paging can be kept on ABS and the transmission of the PDCCH of related schedule information is carried.Therefore, by inciting somebody to action
The mode that the corresponding descending sub frames of aggressor cell are configured to ABS to coordinate heterogeneous network presence of intercell interference address only
Victim UE are in data channel and the interference problem of fractional control channel, and SIB/Paging and PDCCH still can be subject to strong
Interference, it is impossible to ensure reliable communication quality, greatly have impact on user's impression.
