Description

The method and system that long-term evolving network co-frequency neighbor cell is measured

Technical field

The present invention relates to wireless communication field, the method and system that particularly a kind of long-term evolving network co-frequency neighbor cell is measured.

Background technology

Along with user constantly increases the demand of mobile data services, mobile network's speed will increase rapidly in future, and following a large amount of throughput of system will occur in indoor and focus scene.Mobile communications network also will, from original taking single level, macrocellular networking as main, change to multi-level, grand micro-isomery networking.The center of gravity of mobile communications network construction also can become to be covered as continuously basis from being covered as continuously main target, to meet outdoor focus, indoor capacity increase demand as main target.

Following Long Term Evolution (Long Term Evolution, LTE) in heterogeneous network except traditional macro base station, also can exist with respect to the less transmitting node of traditional macro base station transmitting power, for example Pico cell (Pico cell) base station, femtocell (Femto cell) base station, and for the relay station (Relay) of signal relaying, below these nodes are referred to as to micro-base station.Volume and the transmitting power of micro-base station are less, are convenient to dispose neatly in network, introduce this base station slightly in macrocellular network, can provide good guarantee for indoor and covering focus scene.

But, introduce new low power nodes and changed the topological structure of legacy network, because micro-base station transmitting power is low, under identical networking condition, down channel can be subject to the strong interference of macro base station, causes micro cellular system hydraulic performance decline.

Shown in Figure 1, Fig. 1 illustrates that the community of heterogeneous network in long-term evolving network covers schematic diagram.Wei Wei base station, A2 region normal coverage area in Fig. 1, micro-base station down signal in this region is greater than macro base station, automatically accesses micro-base station at this region user terminal (UE) according to signal strength signal intensity.In Fig. 1, the large region of A1 is macro base station coverage area, and in this region, macro base station downstream signal is obviously greater than micro-base station, and user terminal accesses macro base station automatically according to signal strength signal intensity.In Fig. 1, A3 region is that macro base station downstream signal is greater than micro-base station area, user terminal should access macro base station, in order to reduce the flow pressure of macro base station, cell extension (Cell Range Extension has been proposed, CRE) technology, wish user terminal in A3 region still scheduling switch to micro-base station.

At present, 3GPP has introduced CRE and blank subframe (Almost Blank Subframe, ABS) technology almost in LTE Rel.10 version simultaneously.Shown in Figure 2, be that macrocellular does not send any user data and control information in specific descending ABS subframe, between the data that this technology is avoided existing between grand microcellulor by the method for time-division, disturb, even if thereby make user terminal also can access microcellulor in the stronger overlay area of macrocellular signal, and carry out proper communication, thereby improve the overall spectrum utilization ratio of heterogeneous network.

But for realizing backwards compatibility, 3GPP standard regulation macrocellular still as usual sends synchronizing information (PSS/SSS) and broadcast message (PBCH) in ABS subframe.Shown in Figure 2, Fig. 2 illustrates the frame structure schematic diagram of the ABS subframe of sampling in heterogeneous network in long-term evolving network.In ABS subframe, there is above-mentioned synchronizing information and broadcast message, when user terminal carries out cell reselection in heterogeneous network, measure for co-frequency neighbor cell, because microcellulor synchronizing channel is subject to the strong interference of macrocellular synchronizing channel, user terminal uses correlation detection principle cannot detect Microcell synchronizing signal, thereby cannot adopt CRE technology to be switched to microcellulor, for example, in Fig. 2, macrocell SF3, SF4 are ABS subframe, and synchronizing information wherein and broadcast message produce interference to micro-base station far-end user in Microcell.

Shown in Figure 3, Fig. 3 illustrates the relatively schematic diagram of result that in prior art, co-frequency neighbor cell is measured.As shown in Figure 3, the synchronizing signal that user terminal uses correlation detection principle to detect S2 community, micro-base station cannot reach detection threshold value, error detection occurs, thereby cannot be switched to S2.If user terminal adopts the interference that complexity is higher to eliminate (Interference Cancellation, IC) algorithm improves Microcell synchronization signal detection performance, can cause again by the weak synchronization signal detection of other macro base stations out, there is error detection, report by mistake, as shown in Figure 3, the synchronizing signal that sampling interference cancellation algorithm detects macro base station S3 is higher than detection threshold value, or the microcellulor synchronizing signal of non-CRE is detected as the microcellulor synchronizing signal that adopts CRE technology, cause metrical information to produce deviation.In addition, user terminal does not add the employing IC algorithm measurement synchronizing signal of differentiation, also can increase the complexity of synchronization signal detection, improves mobile phone cost, reduces the cell phone standby time.

Visible, when user terminal carries out cell reselection in heterogeneous network in prior art, owing to cannot selecting suitable Measurement Algorithm to carry out signal measurement, not only produce community error detection, the problem that reports by mistake, but also may increase the complexity of synchronization signal detection.
