Description
Technical field
The present invention relates to the communications field, in particular to a kind of metrical information configuration, report method and device of transmission node.
Background technology
For miscellaneous service contents such as voice, grouped data, broadcast is provided to user, cordless communication network is by widespread deployment.In order to meet the growing communication quality of user and traffic rate demand, constantly evolution of wireless communication technology (wireless network) development.
Cordless communication network is from global system for mobile communications (Global System For Mobile Communication, referred to as GSM)/general wireless packet service system (General Packet Radio Service, referred to as GPRS) 2nd generation/2.5th third generation mobile communication network evolves to universal mobile telecommunications system (Universal Mobile Telecommunications System, referred to as UMTS) the 3rd third generation mobile communication network.And in order to improve better frequency spectrum service efficiency, meet the wireless communication needs that user rapidly increases, third generation partner program (The 3rd Generation Partnership Project, referred to as 3GPP) tissue proposed again the 4th third-generation mobile communication technology " Long Term Evolution " (Long Term Evolution on the basis of UMTS, referred to as LTE) and further evolution technology " senior Long Term Evolution " (Long Term Evolution Advance, LTE-A).
Cordless communication network can be supported multiple access by shared system resource conventionally, in addition the mobility of cordless communication network support terminal equipment (User Equipment, referred to as UE).In view of this consideration, in order effectively to utilize system resource that the service communication of high-quality is provided for user simultaneously, cordless communication network need to carry out effective resource management.Take LTE system as example, control station (comprises evolved macro base station Macro enhanced NodeB or is abbreviated as Macro eNB, evolved Home eNodeB Home eNB or be abbreviated as HeNB, far end radio frequency head Remote Radio Head or be abbreviated as RRH, relay station Relay Node or be abbreviated as RN, evolved micro-base station Pico eNB etc.) based on to the measurement of uplink reference signals or the measurement to downlink reference signal based on UE, can obtain quality of wireless channel, and consider the management that other factors are carried out Radio Resource, such as considering quality of wireless channel, service distribution, adjacent area load, hardware resource, operator's policy etc. connects mobility and controls (Connection Mobility Control, referred to as CMC), consider quality of wireless channel and resource service condition and carry out scheduling of resource (Resource Scheduling, referred to as RS), consider quality of wireless channel, business load carries out interference coordination (Inter-cell Interference Coordination, referred to as ICIC) etc.Wherein, to downlink reference signal, measurement refers to that UE measures the reference signal (Cell-specific reference signals, referred to as CRS) of cell-specific and gives eNB measurement feedback to UE.Meanwhile, consider the fluctuation that physical layer is measured, in standard, at high level, introduced L3 filtering at present, utilize historical measurement result to carry out the result of current measurement certain level and smooth.
In order to meet the performance index of LTE-A, 3GPP has introduced multipoint cooperative (Coordinated Multi Point, referred to as CoMP) transmission technology.The principle of CoMP technology is to utilize on geographical position separated a plurality of eNB, or claims a plurality of transmission nodes (Transmission Point, referred to as TP) to participate in and the transfer of data of same UE simultaneously.Use CoMP technology can effectively improve community marginal user performance, effectively suppress presence of intercell interference; And, can also increase the covering of high data rate, thereby improve the throughput of cell edge, further improve throughput of system.
When using CoMP technology, the signal quality that simultaneously participates in the transmission node of transmission in order to weigh these, 3GPP has introduced channel state information reference signals (Channel-State Information reference Signal, referred to as CSI-RS).UE, when transfer of data, can feed back to network side by the channel state information reference signals that participates in the transmission node of transmission in the feedback information of transfer of data, and network side carries out dynamic dispatching by this information of use.
As shown in Figure 1, in CoMP use scenes, the transmission node number that can participate in transmission is often greater than the transmission node number that UE is used simultaneously, network side need to be selected the transmission node transmitting for simultaneously from numerous transmission nodes, therefore network side need to be known the signal quality of all transmission nodes, obtains the channel state information reference signals that all transmission nodes are corresponding.Accordingly, UE will measure transmission node.But, how to define the measuring object of UE in described measuring process (Measurement Object, or be abbreviated as MO) still unclear.
For instance, for measuring with frequency (intra-frequency) and alien frequencies (inter-frequency), prior art specifying measurement object is a carrier frequency.Be associated with this carrier frequency, can configure the certain bias of a series of communities and without " blacklist " community of measuring or reporting.But in CoMP use scenes, the transmission node of simultaneously communicating by letter with UE does not have dividing of Serving cell and neighbor cell.Therefore need in measuring object, redefine associated transport node.
Accordingly, in the metrical information reporting, also need the corresponding relation of clear definition transmission node and reporting information.In prior art, by cell ID, solve this correspondence problem.But due to transmission node do not have Serving cell and neighbor cell minute minute, prior art is not too applicable.Especially, as shown in Figure 2, if all transmission nodes are used same cell ID, cell ID before obviously cannot be realized this correspondence.
In current measuring technique, for the problems referred to above, all there is no good total solution.For example, to an index of each CSI-RS definition, (maximum number that configures CSI-RS in considering prior art is 8 in the measuring object suggestion of configuration CSI-RS at present technology, the expense of an index is 3bit), so must configure the relative index to a 3bit of each CSI-RS when allocating and measuring object, also must comprise index and corresponding measurement result in the measurement result reporting.If periodically report the measurement result on all CSI-RS resource, the expense of having avoided index configurations and having reported, but but having increased unnecessary measurement result reports, and causes increasing empty overhead.
For the larger problem of the empty overhead of measurement report in correlation technique, effective solution is not yet proposed at present.
