Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention for application scenarios be SCNs, in the network of small-cell, have a macro base station, a large amount of micro-base station of spreading in macro base station coverage, micro-base station is connected with macro base station by wired.In embodiments of the present invention, divided into groups with certain standard in small-cell, to the corresponding silent mode of different packet configuration (MutingPatten), small-cell in respective packets is carried out mourn in silence (Muting) in corresponding subframe (hereinafter referred to as subframe of mourning in silence), so just can reduce the interference between different small-cell.
Further, in order to improve transmission quality further, above-mentioned silent mode can be coordinated, different measurement patterns is formulated to the UE that the small-cell in the grouping of different small-cells is served, measure according to this measurement pattern, better can obtain the actual interference situation between each small-cell, according to this actual interference situation carry out dispatching (as, determine transmission code rate etc.) just can improve efficiency of transmission, thus the interference reduced between small-cell is on transmitting the impact caused.
As shown in Figure 1, be a specific embodiment of the base-station scheduling method in the embodiment of the present invention, the method comprises the steps.
101, the small-cell for belonging to different grouping configures corresponding silent mode and micro-base station of each small-cell of notice covering, described micro-base station is the micro-base station be connected with macro base station, define the subframe of mourning in silence in Frame in described silent mode, do not send signal mourning in silence in subframe.
Wherein, for the small-cell belonging to different grouping configure corresponding silent mode time, can be numbered described different silent mode, described numbering notice is covered micro-base station of each small-cell.As long as the concrete silent mode in micro-base station corresponding to pre-configured numbering.To reduce expense.
If the cycle of setting silent mode (MutingPattern) is 10 subframes, in Long Term Evolution (LongTermEvolution, LTE) related protocol, defines 10 subframes correspond to 10 milliseconds of (ms.) then configurable silent mode as shown in Figure 2, in this example, 0/10,1/10,2/10 etc. represents in this silent mode the ratio of subframe in 10 subframes of mourning in silence.
A grouping step can also be comprised: according to being linked into the user terminal number of each small-cell, divide into groups as the number of the strong jamming community of the user terminal under other small-cells or the small-cell of Reference Signal Received Quality to described micro-base station coverage of the user terminal that is linked into each small-cell in each small-cell before this step.
Certainly, grouping standard also can be not limited to foregoing description, does not do repeating one by one herein.
Be understandable that, will definitely to find out from above-mentioned several group markups, its concrete group result may be time dependent, as being different in the user terminal number not being linked into each small-cell in the same time, then its group result may be different, thus in embodiments of the present invention, can periodically for the small-cell belonging to different grouping configures corresponding silent mode.
102, obtain under described each small-cell is configured to described silent mode, the user terminal of described each small-cell carries out the measurement result fed back after channel quality instruction is measured, and is that described user terminal is dispatched according to the silent mode of described measurement result, described each small-cell.
The channel quality instruction measurement described in this step can take existing metering system, also can adopt and carry out according to measurement pattern the mode measured.A kind of mode after adopting, can improve signal gain during transmission further, improves transmission quality.Then now, this step can comprise following process:
A, according to configuration described silent mode be linked into described each small-cell user terminal allocating and measuring pattern and notify described user terminal, define the subframe of mourning in silence in Frame, high interference subframe and low interfering subframe in described measurement pattern.
If by silent mode allocating and measuring pattern as shown in Figure 2, example is grouped into 2, small-cell wherein in the 1st grouping adopts the silent mode of 0/10 in Fig. 2 to carry out Muting, and the community in the 2nd grouping adopts the silent mode of 5/10 in Fig. 2 to carry out Muting, then configurable measurement pattern as shown in Figure 3.
As can be seen from the silent mode that this measurement pattern is corresponding, subframe of not mourning in silence in the silent mode adopted in grouping 1,1 interference caused grouping 2 of thus dividing into groups is stable; And there is a subframe of mourning in silence every a frame in the silent mode that adopts in 2 of dividing into groups, become when thus grouping 2 to the interference that grouping 1 causes is (, Signal transmissions is not had then not disturb when occurring mourning in silence subframe, when not being there is Signal transmissions when mourning in silence subframe then can cause interference).Accordingly, then during allocating and measuring pattern, known in grouping 1, when in grouping 2 for mourn in silence subframe time, little to the interference of the subframe of grouping 1, then now the subframe of configuration packet 1 is low interfering subframe; When being non-silence subframe in grouping 2, large to the subframe interference of grouping 1, then now the subframe of configuration packet 1 is high interference subframe.In like manner, if the subframe in grouping 2 is mourned in silence subframe, then in measurement pattern, this sub-frame configuration becomes to mourn in silence subframe, and UE does not need to measure in this subframe, and for non-silence subframe, is then configured to high interference subframe.
Certainly, be illustrated in figure 3 the situation of two groupings, also may there is the situation of more groupings, the rest may be inferred, do not repeat herein.Certainly, consider the above-mentioned configuration principle measuring subframe, when subframe is mourned in silence in configuration, can as shown in Figure 2 like this, can by sub-frame configuration of mourning in silence in roughly the same subframe position in different silent mode, as, just there is the subframe of mourning in silence being configured in same position in 1/10 and 2/10 these two kinds of silent modes; Like this, when allocating and measuring pattern, than the interference effect being easier to confirm to be configured with between the grouping of different silent mode.
B, obtain described user terminal according to described measurement pattern carry out channel quality instruction measure after the measurement result of feedback, and be that described user terminal is dispatched according to described measurement result, the silent mode of described each small-cell and the measurement pattern of described user terminal.
Can be specifically: if the subframe of current small-cell is normal sub-frames, and be high interference subframe then adopt the high interference channel quality instruction measurement result of user terminal feedback to dispatch in this step; If the subframe of current small-cell is normal sub-frames, and be low interfering subframe, then adopt the low interference channel quality instruction measurement result of user terminal feedback to dispatch; If the subframe of current small-cell is subframe of mourning in silence, then the user terminal in this small-cell is not dispatched.
Accordingly, then user terminal is specially when measuring: described user terminal, when carrying out the instruction of high interference channel quality and measuring, is measured in high interference subframe, obtains high interference channel quality instruction measurement result; Described user terminal, when carrying out the instruction of low interference channel quality and measuring, is measured in low interfering subframe, obtains low interference channel quality instruction measurement result.

204, central control unit determines measurement pattern (Pattern) according to the MutingPattern that each divides into groups, and by high-rise configuration signal (such as RRC signaling), measurement pattern is notified the UE that in each grouping, each small-cell is served.
205, UE carries out the measurement of corresponding channel quality instruction (ChannelQualityIndicator, CQI) according to measurement Pattern.That is, when carrying out high interference CQI and measuring, then measure in high interference subframe and calculate corresponding Signal to Interference plus Noise Ratio (SignaltoInterferenceplusNoiseRatio, SINR), SINR is obtained corresponding high interference CQI according to after corresponding process; When carrying out low interference CQI and measuring, then measure in low interfering subframe, obtain low interference CQI.
206, measurement feedback is given service small-cell or macrocell (namely feeding back to corresponding micro-base station or macro base station) by UE, and measurement result is sent to central control unit by small-cell or macrocell.
207, central control unit is according to measurement result, and dispatches according to the MutingPattern of each small-cell, namely controls each micro-base station and specifically dispatches.Concrete, if the subframe of current small-cell is normal sub-frames, further, if according to measurement Pattern, present sub-frame is high interference subframe, then adopt the high interference CQI of UE feedback to dispatch; If according to measurement Pattern, present sub-frame is low interfering subframe, then the low interference CQI of UE feedback is adopted to dispatch.If the subframe of current small-cell is Muting subframe, then the UE in this small-cell is not dispatched.
