Description
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of report method of measurement report, communication node and system.
Background technology
Long Term Evolution (Long Term Evolution, referred to as LTE) project is G mobile communication (Third Generation, referred to as 3G) evolution, but it is not forth generation mobile communication technology (the Fourth Generation that people generally misread, referred to as 4G), but a transition between 3G and 4G technology, it improves and enhances the aerial access technology of 3G, it adopts OFDM (Orthogonal Frequency Division Multiplexing, referred to as OFDM) technology and multiple-input and multiple-output (Multiple Inputs and Multiple Outputs, referred to as MIMO) technology, that is: multi-antenna technology is as the sole criterion of wireless network evolution.Senior Long Term Evolution (LTE-Advanced, referred to as LTE-A) is the follow-up evolution of LTE technology.In order to meet the various demand parameters of 4G, the several key technologies for LTE-A are suggested, and comprise carrier aggregation, coordinate multipoint transmission and reception, relay transmission and multiple antennas enhancing etc.
Heterogeneous network system is a kind of novel network architecture proposed in LTE, as shown in Figure 1, in this new framework, multiple maximum transmission power can be settled in the geographical coverage area of a macro base station (macro cell) lower and the little base station (small cell) that coverage is less, in a macro base station coverage, little base station more close for geographical position can be considered as one bunch (being called for short cluster), little base station mainly can be divided into two large classes: a class is placed in outdoor, is called pico, an other class is placed in indoor, be called Home eNodeB (Home eNodeB, be called for short HeNB), if the number of the small cell placed in a macro cell overlay area is less, within such as four, we are then regarded as the sparse deployment scenario of small cell, although the interference under this scene between small cell still exists, but not main interference, it mainly disturbs from macro cell, in the prior art, almost blank subframe (almost blank subframe is proposed for the sparse deployment scenario of small cell, be called for short ABS) technology, this technology proposes the base station of strong jamming type, such as macro cell does not send data in the subframe of configuration, to reduce small cell, the interference of edge UE in such as pico cell.If the number of the small cell placed in a macro cell overlay area is more, such as more than ten, we are then regarded as small cell dense deployment scene, and the interference under this scene between small cell can be quite serious.Be currently suggested a lot of interference coordination schemes, comprise power control, the switch state of small cell, dynamically subband selection etc., the decision-making of these schemes all depends on correct measurement result.
In prior art, the event of down-run survey comprises the common frequency measurement of Serving cell and adjacent cell and the different-frequency measure of adjacent cell, and measurement report reporting schemes comprises periodic report, and event triggering reports and periodic event triggering reports three kinds of modes.What out-hole run then belonged to base station realizes behavior, does not limit, but under small cell dense deployment scene, because the small cell around UE is more, still according to such measurement and report mechanism can bring very large power consumption to UE.Meanwhile, too much report measurement results also can waste a lot of interface-free resources, therefore considers to carry out auxiliary down-run survey by planned out-hole run, to reduce number of times and the time that UE carries out down-run survey.Simultaneously, due in some scenarios, small cell may be configured to identical Physical Cell Identifier (Physical Cell Identity is called for short PCI), for UE, different small cell cannot be distinguished and also just cannot measure accurately for different communities.In addition, under up-downgoing time-division (being called for short TDD) pattern, if adjacent sectors configuration is asynchronous, then likely in certain subframe, small cell1 is configured to up, and small cell2 is configured to descending, that is except the UE in adjacent sectors is to except the interference of small cell 1, also there is adjacent small cell2 to the interference of small cell1, so due to descending time domain interference coordination, the interference that small cell1 is subject in different subframe is also different.
In addition, under the scene of small cell dense deployment, single small cell can not only according to oneself independently measurement result enter a judgement, comprise switching, switch, power adjustment etc., also need the measurement result considering adjacent small cell, the measurement result of other small cell considered in same cluster is at least needed to adjudicate, therefore each cluster needs a centralized control processor (Central Controller Unit, be called for short CCU), this CCU may reside on certain small cell, as shown in Figure 2, namely this small cell is called anchor point sector, i.e. anchor cell, or one independently on processing unit, as shown in Figure 3, or radio network processing (the Radio Network Controller in 3G, be called for short RNC) on.
Therefore, in heterogeneous network system, need the measurement result reported according to each small cell by CCU to enter a judgement.But under the scenes such as time domain interference coordination, the out-hole run result difference of each subframe may be very large.In addition, if small cell unifies report measurement results simultaneously, CCU can only add up the measurement result that the small cell in a certain period of time cycle reports and carry out decision-making, then have following three shortcomings:
1) CCU cannot process in real time, needs larger buffer memory to store the measurement result of a period of time;
2) ageing decline, the measurement report of some small cell reports rear needs to wait for a period of time just can receive decision-making response, such as: suppose that the RNC decision-making time is T0, T10, T20..., certain small cell is at T1 reporting measurement reports, and the decision-making time is T10, so needs to wait for an almost complete decision-making period;
3) interval is reported to there is restriction to twice measurement, such as: within a decision-making period, certain small cell has reported multiple measurement result, obviously, using last measurement result as decision-making reference, should will cause two problems like this: one is that the measurement result reported before this small cell is meaningless; Two is that time of reporting of hypothesis twice measurement is very close to (it is possible for reporting for event flip-over type), and it is very close with the decision-making time that this twice is called time, then likely cause error, small cell does not know the decision-making made according to which measurement report, thus causes judgement inaccurate.
