Description
Technical field

Background technology
In the mobile communication system in future, there is the application scenarios of hybrid network, namely in the cellular network coverage with good planning that macro base station forms, there is the covering of a plurality of little base stations.This is so that some zone forms the multitiered network that is repeated to cover by macro base station and little base station.
Fig. 1 is hybrid network transmission covering scene schematic diagram.Wherein, MeNB represents macro base station, and MUE represents to belong to the mobile device of MeNB base station; The little base station of pico.MUE1, MUE2, MUE3 are illustrated respectively in the interior mobile device of coverage of macro base station.As seen from Figure 1, if macro base station sends the signal that the high power signal will disturb little base station of its covering to send.
Therefore, the R10 standard of 3GPP standard proposed that in hybrid network macro base station can adopt ABS subframe (accurate blank subframe) and little base station of being disturbed between carry out the coordination of descending interference.Namely, macro base station does not send unicast data traffic on the ABS subframe, reduces descending interference to described little base station with this.
In order to improve the power system capacity of whole hybrid network, the R11 standard proposes macro base station for the hybrid network interference problem and send unicast data traffic with lower performance number on original ABS subframe, so that this residential quarter mobile device can receive unicast data traffic.This subframe with lower performance number transmission unicast data traffic is called the accurate blank subframe of non-zero (non-zero ABS subframe).
In order to make things convenient for mobile device correctly to receive unicast data, mobile device can be told in the high-level signaling mode with the downlink transmission power parameter of unicast data in the base station.Obviously, in non-zero ABS subframe, correctly receive unicast data in order to make things convenient for mobile device, the base station also needs lower unicast data downlink transmission power parameter is informed mobile device.
After reaching common understanding with regard to the sub-frame resources that needs protection in macro base station and contiguous little base station; can form one and form signaling by Normal subframe and non-zero ABS subframe; and by described macro base station with this signaled subordinate mobile device, and the downlink transmission power that the non-zeroABS subframe adopts informed subordinate's mobile device.
At present, the notice signaling of subordinate's mobile device there is following dual mode:
Fig. 2 is without in the grouping situation, the signaling pattern that the base station sends.Wherein, the base station is sent to all mobile devices that it is covered in the mode of broadcasting with this subframe pattern.
Fig. 3 is the signaling pattern that the grouping of base station movement-based equipment designs.Wherein, described base station group-based is sent to mobile device in this grouping with the performance number that sends data in the accurate blank subframe of non-zero in corresponding signaling pattern and this signaling pattern, determines to obtain the start-stop sequential of unicast data and the performance number that sends these data in order to receive the mobile device of signaling pattern based on described signaling pattern.Yet, when mobile device had not only belonged to grouping A but also belong to grouping B, this mobile device may be received two kinds of different subframe patterns sometime, if corresponding to certain subframe, the subframe classification of two kinds of different subframe patterns is different, then this mobile device transmitted power that None-identified is received is normal sub-frames, or the accurate blank subframe of non-zero.
Same base station is identical to the power that each grouping sends unicast data in the aforesaid way, and this is so that the degree of being disturbed of the little base station near apart from the base station is higher, and perhaps the described base station of distance mobile device far away can't receive the data that send with low-power.

Wherein, when described macro base station sends scope that the power of data can cover and refers to that described macro base station sends data based on described power in the accurate blank subframe of non-zero, the maximum distance that data can be transmitted.This shows, the scope that described macro base station can cover with different power transmission data in the accurate blank subframe of non-zero is difference also, causes described macro base station also different to the interference of the little base station in its coverage.For example, as shown in Figure 5, macro base station MeNB can protect base station pico 1, base station pico 2 and base station pico 3 interference-free when the accurate blank subframe of non-zero sends data with R1 power; Sending data in the accurate blank subframe of non-zero with R2 power is to protect base station pico 2 and base station pico 3 interference-free; Sending data in the accurate blank subframe of non-zero with R3 power can protect base station pico 3 interference-free.
Particularly, described transmitting system sends the scope that the power of data covers based on macro base station in the accurate blank subframe of non-zero, and the mode that the mobile device in the described macro base station institute coverage is divided into groups includes but not limited to:
1) poor based on the macro base station scope that adjacent two different power cover in the accurate blank subframe of non-zero divides into groups the mobile device in the described macro base station institute coverage, so that the mobile device zero lap between each grouping.For example, as shown in Figure 5, the scope that macro base station MeNB covers when the accurate blank subframe transmitted power of non-zero is R1 is Group1, the scope that covers when the transmitted power of the accurate blank subframe of non-zero is R2 is Group2, the scope that covers when the transmitted power of the accurate blank subframe of non-zero is R3 is Group3, then described transmitting system with the mobile device in the scope Group1 as the grouping A, with the mobile device in the difference range of scope Group1 and scope Group2 as grouping B, with the mobile device in the difference range of scope Group2 and scope Group3 as the C that divides into groups etc.
The scope that 2) can cover in each transmitted power of the accurate blank subframe of non-zero based on macro base station is divided into groups the mobile device in the described macro base station institute coverage.For example, as shown in Figure 6, the scope that macro base station MeNB covers when the transmitted power of the accurate blank subframe of non-zero is R1 is Group1, the scope that covers when the transmitted power of the accurate blank subframe of non-zero is R2 is Group2, the scope that covers when the transmitted power of the accurate blank subframe of non-zero is R3 is Group3, then described transmitting system is made as grouping 1 with scope Group1 with interior mobile device, scope Group2 is made as grouping 2 with interior mobile device, scope Group3 is made as grouping 3 with interior mobile device.So, the mobile device in each grouping has overlapping.
Need to prove, those skilled in the art should understand that, it is not certain static state that described transmitting system is divided into groups the mobile device in the macro base station institute coverage, and described transmitting system can be divided into groups the mobile device in the macro base station institute coverage based on predefined rule of classification termly.
In step S2, described transmitting system generates corresponding subframe by described macro base station based on a plurality of different capacity values that send data in the accurate blank subframe of non-zero and coordinates signaling, and described subframe is coordinated signaling is sent to mobile device in each grouping.Wherein, described subframe is coordinated signaling and is comprised any type of signaling that is made of normal sub-frames and the accurate blank subframe of non-zero, and preferably, described subframe is coordinated signaling and included but not limited to radio frames pattern, frame etc.
Particularly, when the mobile device zero lap in each grouping, a plurality of different capacity values that described transmitting system sends data based on macro base station mobile device in each grouping in the accurate blank subframe of non-zero generate the subframe coordination signaling of respective packets.
For example, referring to Fig. 5, macro base station MeNB can comprise R1, R2 and R3 to the performance number of grouping A transmission data in the accurate blank subframe of non-zero, the performance number that sends data to grouping B comprises R2 and R3, then described transmitting system is held consultation based on a plurality of different capacity values that send data to each grouping and base station pico1, pico2 and pico3, thereby generating the subframe coordination signaling that sends to grouping A is 1101101011, coordinating signaling to the subframe of grouping B is 1111101011, wherein 1 represents normal sub-frames, the accurate blank subframe of 0 expression non-zero.Mobile device MUE1 can obtain data in the 3rd, 6,8 subframe thus, mobile device MUE2 can obtain data in the 6th and 8 subframe, simultaneously, so that base station pico1 can the 3rd, 6,8 the accurate blank subframe of non-zero position on interference-free, base station pico2 and base station pico3 can be interference-free on the accurate blank subframe of the 6th and 8 non-zero position.
Mobile device in each grouping has when overlapping, and the same performance number that described transmitting system sends data based on described macro base station mobile device in each grouping in the accurate blank subframe of non-zero generates the subframe coordination signaling of respective packets.
For example, referring to Fig. 6, macro base station MeNB is R1 to the performance number that grouping 1 sends data in the accurate blank subframe of non-zero, the performance number that sends data to grouping 2 is R2, the performance number that sends data to grouping 3 is R3, described transmitting system is based on the same performance number from data to each grouping and the base station pico1 that send, pico2 and pico3 hold consultation, determine that it is R1 that each subframe is coordinated in signaling the performance number of the 3rd the accurate blank subframe of non-zero, the performance number of the 6th the accurate blank subframe of non-zero is R1, R2, the performance number of the 8th the accurate blank subframe of non-zero is R1, R2 or R3, described transmitting system is set to 1 greater than the subframe that current group sends the performance number of data, the subframe that sends the performance number of data less than current group is made as 1 (or 0), then described transmitting system generation is 1101101011 to the subframe coordination signaling that grouping 1 sends, the subframe coordination signaling that sends to grouping 2 is 1111101111 (or 1101101111), and coordinating signaling to the subframes of grouping 3 transmissions is 1111111011 (or 1101101011).
Described transmitting system is coordinated the mode that signaling sent with described subframe and included but not limited to: the mode by multicast is coordinated signaling with described subframe and is sent to mobile device in the respective packets etc.
As a kind of preferred version, as shown in Figure 4, subframe of the present invention is coordinated signaling method and is also comprised step S3.
In step S3, described transmitting system is coordinated the corresponding performance number of the accurate blank subframe of each non-zero in the signaling with described subframe and is sent to mobile device in the described grouping.
Particularly, described transmitting system performance number that described subframe is coordinated to send in the accurate blank subframe of each non-zero in the signaling data is sent to the mobile device in the described grouping successively.
For example, it is 1101101011 that the subframe that described transmitting system sends to grouping 1 is coordinated signaling, wherein, the 3rd 0 represented performance number is R1, the 6th 0 represented performance number is R2, the 8th represented performance number is R3, and then described transmitting system is sent to R1, R2 and R3 the mobile device in the grouping 1 successively.
More preferably, described step S3 also comprises step S31 (not giving diagram).
In described step S31, described transmitting system is sent to described mobile device with performance number and the order of each performance number in described subframe coordination signaling that sends data in the described subframe coordination signaling in the accurate blank subframe of non-zero.
For example, it is 1111101011 that the subframe that described transmitting system sends to grouping 2 is coordinated signaling, wherein, 1 expression normal sub-frames, the accurate blank subframe of 0 expression non-zero, described subframe coordinates to send in the signaling data in the accurate blank subframe of non-zero performance number is respectively R2 and R3, and the order that this two performance number is coordinated in the signaling in described subframe is 0001, and then described transmitting system is sent to mobile device in the described grouping 2 with the order of R2, R3 and this two performance number.
Then, in step S4, as shown in Figure 4, described receiving system is determined the real power of the corresponding transmission data of the accurate blank subframe of corresponding non-zero based on the corresponding performance number of the accurate blank subframe of each non-zero in the subframe coordination signaling of obtaining and the described subframe coordination signaling by mobile device.
For example, it is 1101101011 that the subframe that described receiving system is obtained is coordinated signaling, the performance number of obtaining is followed successively by R1, R2, R3, then described receiving system determines that it is R1 that this subframe is coordinated the real power of the 1st the accurate blank subframe transmission of non-zero data in the signaling, the real power of the 2nd the accurate blank subframe transmission of non-zero data is R2, and the real power of the 3rd the accurate blank subframe transmission of non-zero data is R3.
Preferably, described receiving system coordinates to send in the accurate blank subframe of each non-zero in signaling, the described subframe coordination signaling performance number of data based on the subframe of obtaining, and the order information of each performance number determines to send in the accurate blank subframe of each non-zero the real power of data.
For example, it is 1101101011 that described receiving system is obtained the subframe coordination signaling of getting, the performance number that sends data in the accurate blank subframe of each non-zero is respectively R1, R2 and R3, the order information of described each performance number is 000110, then described receiving system determines that based on this order information it is R1 that described subframe is coordinated the real power of the 1st the accurate blank subframe transmission of non-zero data in the signaling, the real power of the 2nd the accurate blank subframe transmission of non-zero data is R2, and the real power of the 3rd the accurate blank subframe transmission of non-zero data is R3.
When receiving many subframes, described receiving system coordinates signaling, and when same position had at least one to be the accurate blank subframe of non-zero in each subframe coordination signaling, described receiving system determined to send the real power of data in the accurate blank subframe of the non-zero of this position based on the corresponding performance number of the accurate blank subframe of each non-zero of described position.
For example, a plurality of subframes obtained of described receiving system are coordinated signalings and performance number is respectively:
Subframe is coordinated signaling A:1111101111 performance number R2
Subframe is coordinated signaling B:1111101011 performance number R3
Then the described receiving system R2 that two subframes coordinated to be located in the signaling performance number minimum in the 6th the accurate blank subframe of non-zero is defined as sending in the accurate blank subframe of non-zero of this position the real power of data.
And for example, a plurality of subframes obtained of described receiving system are coordinated signalings and performance number is respectively:
Subframe is coordinated signaling C:1111101111 performance number R1
Subframe is coordinated signaling D:1111111011 performance number R2
The 6th is the accurate blank subframe of non-zero among the subframe coordination signaling C, and the 6th of son coordination signaling D is normal sub-frames, and then described receiving system determines that the less R1 of this position performance number is for sending the real power of data.
