Description
Technical field
The present invention relates to a kind of wireless technical field, relate in particular to a kind of heterogeneous network cell measuring method, Apparatus and system.
Background technology
For realizing the requirement of high-speed data service to wireless system performance, at present like 3GPP, International Standards Organization such as WiMAX all consider in system, to introduce one type of novel radio node.They are compared with macro base station has lower transmitting power, like the pico base station, and femto base station and via node etc.As shown in Figure 1, the introducing of these new nodes makes system topology isomery more, competes the brand-new interference environment of same wireless resource jointly thereby formed a polytype node.
For avoiding and reduce the phase mutual interference between the heterogeneous network, 3GPP has set up enhanced interference coordination (Enhanced ICIC is called for short eICIC) job at present under the research framework of LTE-A.The interference that the 3GPP proposition is carried out the minizone through the coordination time-domain resource is avoided.Particularly, the part subframe of interference source sub-district is made as near-space subframe (Almost Blank Subframe is called for short ABS), and receives interfered cell only to receive the UE of serious interference at these subframe schedulings.Owing to only send common pilot signal among the ABS, and synchronously, broadcasting (MIB and SIB1) and paging etc. are controlled and data message on a small quantity, thereby can significantly reduce and receive the suffered interference of UE in the interfered cell.
As shown in Figure 2; Simple time domain interference coordination is carried out the method that the interference of minizone avoids and can be given RRM (Radio Resource Management through coordinating time-domain resource; Be called for short RRM)/Radio Link keeps watch on (Radio Link Monitoring is called for short RLM) and measures certain problem of bringing.The RRM measurement refers to that UE measures the RSRP and the RSRQ value of this sub-district and neighbor cell, and these values can be used as the foundation of sub-district switching and gravity treatment.But,,, measure thereby cause possibly can't carrying out RSRP owing to receive interfered cell pilot tone in non-ABS to receive serious interference if in all subframes, all measured by the UE of interfered cell or interference source sub-district to receiving interfered cell to carry out RRM.On the other hand, owing to receive interfered cell in fact in non-ABS, not carry out transfer of data, can cause the estimation of RSRQ poor excessively so in all subframes, carry out the RRM measurement.Opposite, measure if receive the UE of interfered cell or interference source sub-district only in ABS, all RRM to be carried out in the interference source sub-district, then, cause overestimate to the RSRQ value because interference source sub-district pilot signal transmitted in ABS causes the measured value of RSSI lower.Table 1 is depicted as the resource limit of should collect when dissimilar UE carries out the RRM measurement to dissimilar sub-districts.
Table 1
Be the measurement resource limit shown in the support matrix 1, can adopt three types radio resource control (Radio Resource Control is called for short RRC) signaling: 1, the RRC signaling is indicated the measurement resource limit of every PCI/PCI group; 2, the RRC signaling is only indicated a kind of measurement resource limit, this means that (grand, pico femto), measures all types of sub-districts and adopts identical measurement resource limit for UE for a certain type; 3, the measurement resource limit of RRC signaling this sub-district of indication and neighbor cell; This means UE for a certain type (grand, pico, femto); Different measurement resource limit can be adopted with neighbor cell in this sub-district, but all types of neighbor cell all must adopt identical measurement resource limit.
Above-mentioned the 2nd and 3 type RRC signaling all will cause measurement result inaccurate.Though the 1st type RRC signaling can guarantee the measurement result entirely accurate, need increase more signaling consumption for this reason.3GPP confirms at present, and for FDD, the repetition period of resource limit is 40ms; For TDD, the repetition period of the resource limit of uplink and downlink timeslot proportioning Class1-5 is 20ms, and the repetition period of the resource limit of uplink and downlink timeslot proportioning type 0 is 70ms, and the repetition period of the resource limit of uplink and downlink timeslot proportioning type 6 is 70ms.This means, measure the resource limit indication for each PCI needs 20～70 bits.With FDD is example, compares with type 2, and the UE with N neighbor cell needs 40 * N additional bits expense; Compare with type 3, the UE with N neighbor cell needs 40 * (N-1) individual additional bits expenses.

Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.In following examples, the terminal can be UE or other equipment, and network side can be base station or other equipment.
Method embodiment
As shown in Figure 1, no matter the UE of which kind of type measures the sub-district of which kind of type, all only exists to receive resource limit and do not receive two kinds of situation of resource limit.Therefore; The present invention proposes; For reducing the extra signaling consumption that produces, can notify the sub-frame resources limited case of the tested sub-district of UE and tested sub-district when measuring, whether to receive resource limit, UE just can accurately measure the RRM/RLM of tested sub-district according to these information.
As shown in Figure 3, heterogeneous network cell measuring method embodiment of the present invention may further comprise the steps:
Subframe is measured restricted information also can measure the numbering of limitation arrangement in all subframes measurement limitation arrangement set for the subframe of tested sub-district; For example; The subframe measurement limitation arrangement that is provided with 10 types in advance is stored among the UE; The base station sends to UE with the numbering of the required employing subframe measurement in tested sub-district limitation arrangement at every turn, and UE searches corresponding subframe according to this numbering and measures limitation arrangement;
For example; Serving cell for the UE place; This cell measurement restricted information can indicate Serving cell when measuring, whether to receive resource limit in the following manner: whether (1) is measured restricted information according to said subframe with the data indication Serving cell of 1 bit and is adopted the measurement resource limit; Represent Serving cell to measure restricted information like bit 0 and adopt the measurement resource limit according to said subframe; On behalf of Serving cell, bit 1 measure restricted information not according to said subframe and is adopted the measurement resource limit, or opposite; (2) can comprise Physical Cell Identifier (the Phys Cell Id of Serving cell; Be called for short PCI); Comprise this Serving cell PCI and represent that Serving cell need adopt the measurement resource limit according to said subframe measurement restricted information, otherwise the expression Serving cell need not measured resource limit according to the employing of said subframe measurement restricted information;
Neighbor cell for UE place Serving cell; This cell measurement restricted information can indicate when measuring neighbor cell, whether to receive resource limit in the following manner: (1) indicates whether that with 1 bit measuring restricted information according to said subframe adopts the measurement resource limit to the neighbor cell of certain or some scopes; Measure restricted information like bit 0 representative according to said subframe and adopt the measurement resource limit; Bit 1 representative is measured restricted information not according to said subframe and is adopted the measurement resource limit, or opposite; (2), also can only comprise the PCI of this neighbor cell at the cell measurement restricted information if the neighbor cell of indication measurement has only one; (3) adopt the sub-district ID that measures resource limit with a tabulation indication according to said subframe measurement restricted information, the sub-district in tabulation is not measured restricted information not according to said subframe and is adopted the measurement resource limit, or opposite;
More preferably; Because the PCI of the tested sub-district of different frequency might be identical; The frequency information that then can also add tested sub-district at the cell measurement restricted information, for example: (1) said cell measurement restricted information comprises: need measure the frequency information that restricted information adopts the tested sub-district of measuring resource limit according to said subframe;
(2) the cell measurement restricted information comprises: need measure restricted information according to said subframe and adopt the frequency information of the tested sub-district of measuring resource limit and indicate tested sub-district on the said frequency information whether to adopt the data of 1 bit measuring resource limit;
(3) the cell measurement restricted information comprises: need measure frequency information and the cell ID that restricted information is measured the tested sub-district of resource limit according to said subframe;
(4) the cell measurement restricted information comprises: need measure frequency information and the tabulation that restricted information is measured the tested sub-district of resource limit according to said subframe, comprise the cell ID of the tested sub-district on the said frequency information in the said tabulation;
(5) the cell measurement restricted information is tabulation, comprises in the tabulation to measure frequency information and the cell ID that restricted information is measured the tested sub-district of resource limit according to said subframe;
In the present embodiment, also can the prestore subframe of its Serving cell or neighbor cell of UE is measured restricted information and cell measurement restricted information.In addition, subframe measures restricted information and the cell measurement restricted information is not limited to above-mentioned giving an example, and also can be set to other modes.
When if the subframe of Serving cell and neighbor cell measurement limited case is identical; The base station can only be sent a subframe and measured restricted information, and UE measures Serving cell and neighbor cell respectively according to the cell measurement restricted information that this subframe is measured restricted information and Serving cell that receives and neighbor cell.
In addition, UE is carrying out RRM/RLM when measuring to Serving cell, and whether comprise subframe in the message that can send according to the base station and measure restricted information and measure, as, when receiving subframe when measuring restricted information, measure limited case according to this subframe and measure; When not receiving subframe measurement restricted information, then all subframes are measured.
In the present embodiment, subframe measures restricted information and the cell measurement restricted information is generated according to the type of tested sub-district and the ABS configuration information of interference source sub-district by the base station.Concrete generating mode is following:
(1) as above shown in the table 1, when the subframe that the base station generates is measured UE that restricted information and cell measurement restricted information be used to indicate any kind and is measured by interfered cell only in the ABS of interference source sub-district measurement; Or the UE of any kind measures in all subframes when measuring the interference source sub-district; But, No Assets restriction when PUE measures neighbours pico sub-district;
Only on the common factor of the ABS of interference source sub-district, measure when (2) subframe that generates of base station is measured UE measurement that restricted information and cell measurement restricted information be used to indicate any kind by interfered cell; Or the UE of any kind when measuring the interference source sub-district only the non-ABS in the interference source sub-district measure; Or the UE of any kind measures a while and on the common factor of above-mentioned measurement resource limit, carries out during as interference source with by the sub-district of interfered cell; It is as shown in table 2 below,
Table 2
Only on the common factor of the ABS of all interference source sub-districts, measure when (3) subframe that generates of base station is measured restricted information and cell measurement restricted information and is used to indicate by interfered cell UE measurement by interfered cell; Or interference source sub-district UE all are measured on the common factor of the measurement resource limit of interference source sub-district in its coverage when measuring by interfered cell; Or the UE of any kind only measures at the common factor of the non-ABS of all neighbours' interference source sub-districts when measuring neighbours' interference source sub-district; Or interference source sub-district UE when measuring service interference source sub-district only the non-ABS in service interference source sub-district measure; Or the UE of any kind measures a while during as interference source with by the sub-district of interfered cell, carries out as interference source with on by the common factor of the measurement resource limit of interfered cell at it; It is as shown in table 3 below,
Table 3
Because the ABS of interference source sub-district configuration maybe be different; One possibly disturbed by a plurality of interference sources sub-district by interfered cell; And the interference source sub-district also possibly receive the interference of other interference source sub-districts; Therefore, adopt aforesaid way (2) to generate subframe and measure restricted information and cell measurement restricted information, can be so that UE be more accurate to the RRM/RLM measurement of sub-district.But, come to be that according to aforesaid way (2) UE configuration subframe measures restricted information and cell measurement restricted information, for UE all sub-districts that will measure all need send subframe measurement restricted information and cell measurement restricted information; Can make the base station send signaling in large quantities to UE; Signaling consumption is bigger, therefore, and for the saving signaling expense; Guarantee the accuracy of measurement again simultaneously, can adopt aforesaid way (3) is that UE configuration subframe is measured restricted information and cell measurement restricted information.
(4) to the measurement resource limit of table 3, can do following simplification:
The subframe that the base station generates is measured and is adopted the measurement resource limit when UE that restricted information and cell measurement restricted information be used to indicate any kind measures Serving cell; Adopt the ABS of interference source macrocell when measuring Serving cell like pico UE; Adopt the non-ABS of service macrocell when grand UE measures Serving cell, the grand UE in the femto coverage adopts the ABS of interference source femto sub-district when measuring Serving cell;
The subframe that the base station generates is measured and is adopted the measurement resource limit when UE that restricted information and cell measurement restricted information be used to indicate any kind measures with neighbours pico sub-district frequently; Like the common factor of the ABS of the ABS of interference source sub-district or all interference source sub-districts, can be as shown in table 4 below; When tested sub-district during by a plurality of interference source area interference, subclass can be thought the ABS of a plurality of interference sources sub-district or the common factor of non-ABS;
The subframe that the base station generates is measured and is adopted the measurement resource limit when UE that restricted information and cell measurement restricted information be used to indicate any kind measures alien frequencies neighbours macrocell, like the common factor of the non-ABS of the non-ABS of neighbours' macrocell or all neighbours' macrocells or the ABS of interference source femto sub-district; According to top description, when carrying out common frequency measurement, can be as shown in table 5 below.
Table 4
Table 5
