Description

The configuration of accurate position altogether, defining method and device

Technical field

The present invention relates to the communications field, in particular to the altogether configuration of position of a kind of standard, defining method and device.

Background technology

A large amount of universal along with equipment such as intelligent mobile terminals in recent years, proposes more and more higher demand to the throughput of system.When frequency spectrum resource is more nervous, a large amount of small-cell of synchronous deployment is a kind of effective way improving system effectiveness to obtain large cell splitting gain.Under this background, the concept of super-intensive network (UltraDenseNetwork, referred to as UDN) is arisen at the historic moment.

But the thing followed can cause mobility and interference problem, in order to solve mobility in UDN and interference problem, a kind of effective approach is based on virtual community (also can be referred to as cloudcell), namely each community is sightless for subscriber equipment (UE), for UE, different communities is similar to distributed transmitting antenna.Terminal only needs when Received signal strength to estimate that the channel information obtained detects according to the reference signal of network side configuration, and does not need to know corresponding signal comes from which small-cell (smallcell or Pico).Based on the concept of cell virtual, effectively can solve the mobility problem in UDN, simultaneously network side can configure the community of cooperative transmission signal flexibly according to interference environment, thus avoids the interference between smallcell, even by joint transmission to obtain macro diversity effect.

A kind of mode realizing cell virtual is the thought be separated with user face based on chain of command, and namely the information of chain of command is sent by macro station or specific carrier wave, and the data in user face are sent by small-cell; Simultaneously in order to avoid terminal misconnection enters small-cell, and connect with small-cell, and affect mobility.In small-cell, often do not send primary/secondary synchronizing signal, public reference signal (CommonReferenceSignal, referred to as CRS), broadcast singal etc.

Based on above-mentioned mode, effectively can alleviate the mobility in UDN and interference problem, but following need another problem considered to be terminal to estimate descending large scale parameter (such as: time/frequency deviation, delay spread, frequency expansion etc.).Due to the small-cell that terminal None-identified is different, and small-cell can not send public reference signal again, frequency deviation estimation when thus terminal cannot be carried out based on CRS.

In Long Term Evolution (LTE) R10, except the above-mentioned CRS mentioned, also introduce channel state information reference signals (ChannelStateInformationReferenceSignal, referred to as CSI-RS), but the CSI-RS configurations in current system is unfavorable for that frequency deviation is estimated.Fig. 1 is the pattern schematic diagram of different port RE in a set of CSI-RS according to correlation technique.As shown in Figure 1, in this figure illustrate the pattern of different port resource element (ResourceElement, referred to as RE) in given a set of CSI-RS.As can be seen from the figure, the RE often overlapping CSI-RS corresponding is at adjacent two OFDM (OrthogonalFrequencyDivisionMultiplexing, referred to as OFDM) on symbol, therefore, this configuration limits the performance (the non-constant of ability of restraint speckle) that frequency deviation is estimated.It should be noted that in LTE, the CSI-RS port 0 ~ 7 in Fig. 1 corresponds respectively to port one 5 ~ 22 in the protocol.What wherein illustrate in figure is the configuration mode schematic diagram of wherein a set of CSI-RS, and in LTE, different communities can configure CSI-RS on different running time-frequency resource positions, but basic pattern is consistent.Concrete, the CSI-RS mapping mode under different configuration is shown below:

a k , l ( p ) = w l ′ ′ · r l , n s ( m ′ )

Wherein,

k = k ′ + 12 m + - 0 forp ∈ { 15,16 } , normalcyclicprefix - 6 forp ∈ { 17,18 } , normalcyclicprefix - 1 forp ∈ { 19,20 } , normalcyclicprefix - 7 forp ∈ { 21,22 } , normalcyclicprefix - 0 forp ∈ { 15,16 } , extendedcyclicprefix - 3 forp ∈ { 17,18 } , extendedcyclicprefix - 6 forp ∈ { 19,20 } , extendedcyclicprefix - 9 forp ∈ { 21,22 } , extendedcyclicprefix

l = l ′ + l ′ ′ CSIreferencesignalconfigurations 0 - 19 , normalcyclicprefix 2 l ′ ′ CSIreferencesignalconfigurations 20 - 31 , normalcyclicprefix l ′ ′ CSIreferencesignalconfigurations 0 - 27 , extendedcyclicprefix

w l ′ ′ = 1 p ∈ { 15,17,19,21 } ( - 1 ) l ′ ′ p ∈ { 16,18,20,22 }

l"=0,1

m = 0,1 , . . . , N RB DL - 1

Wherein, (the k' possible when normal CP (normalCP) and expansion CP (extendedCP), l') value is as shown in following table 1 and table 2, and wherein k', l' represent subcarrier relative indexing and the OFDM symbol relative indexing of each PRB in a time slot respectively.

Table 1 is under expansion CP, (k', l') that CSI-RS mapping pair is answered.As shown in table 1, w l" represent the spread spectrum weighted value on port.

Table 1

Table 2 is under normal CP, (k', l') that CSI-RS mapping pair is answered.It is as shown in table 2,

Table 2

In LTER11, for the problem of CSI-RS frequency deviation estimated capacity difference, be configured with for satisfied standard position (Quasi-Co-Location altogether for often overlapping CSI-RS, referred to as QCL) CRS of relation, terminal can according to CRS estimate large-scale characteristics parameter (such as: time/frequency deviation, delay spread, frequency expansion), and can suppose that the large-scale characteristics parameter on CRS is identical with CSI-RS, wherein, QCL is for characterizing the large scale characteristic relation between antenna port, when meeting QCL relation between title two antenna port A and B, refer to and estimate that the channel large-scale characteristics parameter obtained is suitable for antenna port B equally on antenna port A.Therefore, when in R11, when being configured with the CRS of QCL for CSI-RS, then mean that described CSI-RS port and described CRS port have identical large scale characteristic to the channel of terminal.

But in UDN scene, because smallcell does not send the CRS of cellspecific, thus cannot be realized by the CRS meeting QCL relation for CSI-RS configuration.

In sum, the solution that the UE that cooperates carries out large-scale characteristics parameter Estimation is lacked in a kind of UDN in correlation technique.
