Embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.

Embodiment one

Fig. 1 represents the flow chart of the interference acquisition methods of the timesharing long evolving system described in the embodiment of the present invention one.

Shown in Figure 1, the interference acquisition methods of timesharing long evolving system provided by the invention comprises:

S101: partiting step, described partiting step comprises: adjacent area is divided into the first adjacent area and the second adjacent area, and the physical area index mould three of described first adjacent area is identical with the physical area index mould three of main Serving cell; The physical area index mould three of described second adjacent area is different from the physical area index mould three of described main Serving cell;

S103: interference obtaining step, described interference obtaining step comprises: obtain the interference of described first adjacent area and the interference obtaining described second adjacent area, calculate the interference of described timesharing long evolving system according to the interference of described first adjacent area and the interference simulation of described second adjacent area, be used to guide the described timesharing long evolving system of planning.

In step S101, first the adjacent area of main Serving cell is divided, division according to being whether the physical area index mould three of this adjacent area identical with the physical area index mould three of main Serving cell.Why do such division, reason is in real TD-LTE macro base station, mostly use twin-channel configuration, therefore the RE that all TD-LTE macro base stations carry reference signal RS has 3 kinds of different arrangements, and what determine this sequence is community PCI (physical cell index, physical area index).The physical area index mould three of community determines the seat in the RB of RS place, this community, if when therefore physical area, two neighbor cells index mould three is identical, terminal UE will receive the interference issuing RS from another community when measuring reference signals RS.When physical area, neighbor cell index mould three is not identical, terminal UE just can not receive the RS impact of adjacent cell when measuring RS.Therefore, when calculating the interference of timesharing long evolving system, first above-mentioned differentiation is carried out to neighbor cell.

In step s 103, obtain the interference of described first adjacent area and the interference obtaining described second adjacent area respectively, first adjacent area and physical area index mould three adjacent area identical with the physical area index mould three of main Serving cell, second adjacent area and physical area index mould three adjacent area different from the physical area index mould three of main Serving cell, the interference of the first adjacent area and the interference of the second adjacent area are calculated respectively, the precision of the interference of obtained timesharing long evolving system can be improved.

The present embodiment is distinguished according to physical area index mould three pairs of neighbor cells, and the computational methods of refinement adjacent area interference, therefore improve the computational accuracy of community RS-SINR, so that in the planning instructing timesharing long evolving system.

Preferably, the interference obtaining described first adjacent area in described interference obtaining step comprises: the Reference Signal Received Power obtaining each community in described first adjacent area; The Reference Signal Received Power of summation each community described, obtains the interference of described first adjacent area.

In the present embodiment, due to when the physical area index mould three of main Serving cell is identical with the physical area index mould three of adjacent area, terminal UE will receive the interference issuing RS from another community when measuring reference signals RS, Here it is, and present defined mould 3 disturbs.Therefore, all this type of community RS_RSRP can sue for peace by the interference calculating the first adjacent area.

Preferably, the interference obtaining described second adjacent area in described interference obtaining step comprises: the Reference Signal Received Power obtaining the Physical Downlink Control Channel of described second adjacent area, and be multiplied by the first ratio, obtain Part I interference, described first ratio is the ratio that described Physical Downlink Control Channel accounts for total channel; Obtain the Reference Signal Received Power of the physical down link sharing channel of described second adjacent area, and take advantage of the second ratio and load factor, obtain Part II interference, described second ratio is the ratio that described physical down link sharing channel accounts for described total channel; The interference of described second adjacent area is calculated according to described Part I interference and described Part II interference simulation.

More specifically, when neighbor cell PCI MOD3 is not identical, terminal UE just can not receive the RS impact of adjacent cell when measuring RS, and with this when calculating interference, the interference of this kind of adjacent area needs to discuss according to the configuration of TD-LTE non-slotted channel.

For the sub-hardwood of No. 0-4, because in descending 3,4 work song hardwoods, physical downlink control channel PDCCH occupies total channel about 25%, in No. 0 descending sub-hardwood, Physical Broadcast Channel PBCH and PDCCH channel also occupy total channel about 25%, remaining channel is physical down link sharing channel PDSCH, accounts for total channel about 75%.In TD-LTE system, PDCCH and PBCH is control channel, whether there is business under community and all can have power emission, therefore, when terminal UE resolves the reference signal RS on these two channels of Serving cell, the interference of adjacent area PDCCH and PBCH around will inevitably be subject to.Because this two classes channel occupancy amount is 25%, deriving this interference calculation is the 25% PDCCH_RSRP sum being multiplied by all physics cell index moulds three adjacent area such as not.Owing to whether PDSCH channel there being power relevant with cell business volume, therefore for the reference signal RS that Serving cell PDSCH channel carries, adjacent cell then needs the traffic carrying capacity considering that adjacent cell is descending to its interference, the downlink traffic of adjacent cell is more, it is fuller that PDSCH takies, larger to the RS interference on the PDSCH of Serving cell, deriving this interference calculation is that the 75% PDSCH_RSRP sum being multiplied by all PCI moulds 3 adjacent area such as is not multiplied by the cell load factor again.

In the technique scheme of the present embodiment, due to when neighbor cell PCI MOD3 is not identical, terminal UE just can not receive the RS impact of adjacent cell when measuring RS.Therefore, the RS of adjacent cell simply sues for peace when calculating adjacent cell co-channel interference by former RS_SINR simulation calculation mode, RS when this means any PCI between different districts produces interference, so that emulate the interference signal that the interference signal of trying to achieve is greater than reality, therefore the present embodiment specifically considers that D-LTE non-slotted channel configures, and optimizes the acquisition methods of interference.
