Specific embodiment

To make the object, technical solutions and advantages of the present invention clearer, right below in conjunction with the accompanying drawings and the specific embodiments The present invention is described in detail.

The present invention is not able to satisfy time-frequency tracking performance requirement for the problem that existing TRS, not can guarantee communication reliability, Configuration, detection method, base station and the terminal of a kind of complex tracking reference signal are provided.

As shown in Figure 1, the embodiment of the present invention provides a kind of configuration method of complex tracking reference signal, it is applied to base station, Include:

Step 101, the configuration information of target following reference signal is generated；

It should be noted that the configuration information includes: that (sequential parameter refers to for the sequential parameter of target following reference signal It is parameter needed for the determining target following reference signal symbol, such as the sequential parameter includes the sequence of target following reference signal Column length), whether configure in the instruction information of target following reference signal and the time-frequency configuration parameter of target following reference signal At least one of.

Step 102, according to the configuration information, in the default orthogonal frequency division multiplex OFDM character position of target reference signal Increase mesh in the resource particle of different sub-carrier position or in the resource particle of same sub-carrier location difference OFDM symbol position Track reference signal is marked, complex tracking reference signal is generated；

It should be noted that default OFDM symbol position includes: the OFDM symbol position where the target reference signal Or that is, in this case the OFDM symbol position adjacent with the OFDM symbol where the target reference signal carries out target The increase of track reference signal can both be increased in the OFDM symbol position where target reference signal, can also with mesh Increased in the adjacent OFDM symbol of OFDM symbol where mark reference signal.

It should be noted that the target reference signal refers to existing reference signal；Carrying out matching for track reference signal When setting, the information of target reference signal is first obtained, the extension of corresponding time domain or frequency domain is then carried out to the target reference signal, The complex tracking reference signal that target reference signal after extension is configured as base station.

Step 103, the complex tracking reference signal is sent to terminal.

The complex tracking reference signal is sent to terminal by base station, so that terminal carries out complex tracking reference according to the configuration The detection of signal, to realize that time-frequency tracks.

The complex tracking reference signal extended by target reference signal is sent to terminal by the scheme of the present embodiment, with This both reduced newly-increased track reference signal and caused by resource expense, in turn ensure newly-installed complex tracking reference signal Meet track demand.

It should be noted that step 101 can be base station according to network demand, target following reference signal is voluntarily generated Configuration information is also possible to the configuration information for the target following reference signal that base station directly acquires in preset rules, the default rule Then generally refer to communication standard pre-configuration；When the configuration information of target following reference signal is generated by base station, in step 101 It later, should also include: that the configuration information is sent to by terminal by presetting message；

Wherein, the presetting message include: system message (such as system information block (System Information Block, SIB)), Downlink Control Information (Downlink Control Information, DCI) and high-level signaling (such as wireless heterogeneous networks At least one of (Radio Resource Control, RRC) signaling) in.

The concrete mode for generating complex tracking reference signal is described in detail from time domain and frequency domain angle separately below It is as follows.

One, the bandwidth of temporal tracking reference signal is increased

In this case, it according to the configuration information, is accorded in the default orthogonal frequency division multiplex OFDM of target reference signal Increase the implementation of target following reference signal in the resource particle of number position different sub-carrier position are as follows:

Sub-carrier positions according to the configuration information, in at least side of the default OFDM symbol of target reference signal Target following reference signal is carried in resource particle.

Specifically, which includes: secondary synchronization signal (SSS).

It should also be noted that, in this case, when the time-frequency in configuration information including target following reference signal is matched When setting parameter, the time-frequency configuration parameter is the bandwidth information of target following reference signal, which specifically can be with feeling the pulse with the finger-tip Mark the number of the included subcarrier of track reference signal.

Optionally, when in configuration information including the bandwidth information of target following reference signal, the bandwidth information is obtained Take mode are as follows:

According to formula: B_A-TRS=f (B_sys) obtain target following reference signal bandwidth information；

Wherein, B_A-TRSIndicate the bandwidth information of target following reference signal, B_sysIndicate that system bandwidth (can specifically refer to and be The number of system the included subcarrier of signal).

It should be noted that working as B_A-TRSWhen=0, indicate that target following reference signal is not present.

Above situation one illustrates, causes when the frequency domain bandwidth of the existing reference signal for temporal tracking is not wide enough It, can be in the frequency domain of the existing reference signal of OFDM symbol where the existing reference signal when temporal tracking precision is lower Side or two sides introduce target following reference signal (i.e. additional track reference signal (Additional TRS, A-TRS)).Make The tracking accuracy for obtaining complex tracking reference signal (being made of the existing reference signal and A-TRS) is met the requirements.

Below in practical applications, situation one is illustrated below:

Since the frequency density of SSS is higher, so following range is met the requirements.But since the bandwidth of SSS is limited, institute It is poor with tracking accuracy.For this purpose, can where SSS OFDM symbol SSS frequency domain two sides introduce A-TRS, as shown in Fig. 2, its In, solid box indicates SSS, and dotted line frame indicates A-TRS.Wherein, the configuration information of A-TRS can by base station by system message, Terminal is indicated to by modes such as Downlink Control Information, high-level signalings；It can also implicitly refer to by standard preset or by system bandwidth Show, the implicit instruction can be understood as A-TRS bandwidth be system bandwidth function.

In situation one, the method for increasing temporal tracking reference signal bandwidth is elaborated by taking SSS as an example in this way, so that The temporal tracking precision of complex tracking reference signal reaches requirement, while existing SSS signal is utilized, and reduces expense.

Two, the frequency domain density of temporal tracking reference signal is improved

According to the configuration information, the sub-carrier positions of presetting at equal intervals of OFDM symbol where judging target reference signal are It is no available；

When the sub-carrier positions default at equal intervals of OFDM symbol where the target reference signal are available, in the target Target following reference signal is carried in the resource particle for presetting sub-carrier positions at equal intervals of OFDM symbol where reference signal.

It should also be noted that, presetting sub-carrier positions not at equal intervals when target reference signal place OFDM symbol When available, in the money of the sub-carrier positions identical with default sub-carrier frequency domain position with the OFDM symbol adjacent OFDM symbol Target following reference signal is carried on the particle of source.

Specifically, which includes: channel state information reference signals (Channel State Information Reference Signal, CSI-RS).

It should also be noted that, including the time-frequency of target following reference signal in the configuration information in this case When configuration parameter, the time-frequency configuration parameter is the frequency domain density of target following reference signal, it should be noted that the frequency domain is close Degree refers to target following reference signal ratio shared in the complex tracking reference signal, and the frequency domain density can be Absolute density, or the relative value of the frequency domain density relative to the existing reference signal.

The situation two explanation, when the frequency domain density of the existing reference signal for temporal tracking not enough leads to time domain When following range is smaller, A- can be carried in the equally spaced sub-carrier positions of OFDM symbol where the existing reference signal TRS.So that the following range of complex tracking reference signal (being made of the existing reference signal and A-TRS) is met the requirements.

Particularly, when equally spaced subcarrier position between the adjacent sub-carrier of the existing reference signal place OFDM symbol Set it is unavailable for some reason, can the correspondence sub-carrier positions in adjacent OFDM symbol carry A-TRS.

Below in practical applications, situation two is illustrated below:

Since the bandwidth of CSI-RS is larger, so temporal tracking precision is met the requirements.However, the frequency domain density of CSI-RS is logical It is often lower, for example every 12 subcarriers have a CSI-RS symbol (correspond to a port CSI-RS), thus following range compared with It is small.For this purpose, one or more A-TRS equally spaced can be inserted into where CSI-RS symbol between the adjacent sub-carrier of symbol Symbol, respectively as shown in Figure 3 and Figure 4 so that subcarrier where complex tracking reference signal be on frequency domain it is equally spaced, In, solid box indicates CSI-RS, and dotted line frame indicates A-TRS.

Wherein, the configuration information of A-TRS can be by base station by system message, by Downlink Control Information, high-level signaling etc. Mode is indicated to terminal；It can also be indicated by standard preset.

As shown in figure 3, the frequency domain density of A-TRS is the 1/2 of complex tracking reference signal frequency domain density, i.e. complex tracking is joined The frequency domain density for examining signal is 2 times of CSI-RS frequency domain density；As shown in figure 4, the frequency domain density of A-TRS is complex tracking reference The 2/3 of signal frequency domain density, i.e. the frequency domain density of complex tracking reference signal are 3 times of CSI-RS frequency domain density.

It should also be noted that, when equally spaced subcarrier between the adjacent sub-carrier of the place CSI-RS OFDM symbol Position is unavailable for some reason, can be inserted into one or two A- in the correspondence sub-carrier positions in adjacent OFDM symbol TRS symbol is as shown in Figure 5 and Figure 6 that A-TRS is carried on to OFDM symbol where with CSI-RS is adjacent in Fig. 5 and Fig. 6 On the subcarrier of the OFDM symbol on right side, wherein solid box indicates CSI-RS, and dotted line frame indicates A-TRS.

As shown in figure 5, the frequency domain density of A-TRS is the 1/2 of complex tracking reference signal frequency domain density, i.e. complex tracking is joined The frequency domain density for examining signal is 2 times of CSI-RS frequency domain density；As shown in fig. 6, the frequency domain density of A-TRS is complex tracking reference The 2/3 of signal frequency domain density, i.e. the frequency domain density of complex tracking reference signal are 3 times of CSI-RS frequency domain density.

In this situation two, the method for elaborating to improve temporal tracking reference signal frequency domain density by taking CSI-RS as an example, this Kind mode, so that the temporal tracking range of complex tracking reference signal reaches requirement, while being utilized existing CSI-RS signal, Reduce expense.

It should be noted that increasing track reference signal bandwidth in temporal tracking and improving the method for frequency domain density (i.e. Situation one and situation two) it can be used in combination, especially all it is unsatisfactory in the bandwidth and frequency domain density of the existing reference signal In the case where condition (namely narrower bandwidth and frequency domain density lower).

Three, the time domain density of frequency domain track reference signal is improved

In this case, according to the configuration information, in the same sub-carrier location difference OFDM of target reference signal Increase the implementation of target following reference signal in the resource particle of character position are as follows:

According to the configuration information, in the OFDM symbol position where target reference signal between the OFDM symbol of subcarrier Resource particle on carry target following reference signal.

Specifically, the target reference signal includes: phase complex tracking reference signal (Phase Tracking Reference Signal, PTRS).

It should also be noted that, in this case, when the configuration information includes the time-frequency of target following reference signal When configuration parameter, the time-frequency configuration parameter is the time domain density of target following reference signal, which refers to target Track reference signal ratio shared in the complex tracking reference signal, the time domain density refer to absolute density or phase For the relative value of the time domain density of the existing reference signal.

The situation three explanation, when the minimum time domain interval of the existing reference signal tracked for frequency domain not enough causes It, can be in OFDM where the existing reference signal of subcarrier where the existing reference signal when frequency domain following range is smaller A-TRS (can be and be inserted at equal intervals, be also possible to unequal interval insertion) is inserted between symbol.So that complex tracking reference signal The following range of (being made of the existing reference signal and A-TRS) is met the requirements.

Below in practical applications, situation three is illustrated below:

In general, PTRS usually has the longer duration relative to place time slot (slot), as its time domain density, though It is so configurable, but its original intention is to estimate phase noise.In the case where phase noise is smaller, the time domain density of PTRS It can be relatively low.At this point, following range can be smaller when PTRS is used for frequency domain tracking.For this purpose, can where PTRS subcarrier Adjacent OFDM symbol between be inserted into an A-TRS.Specific implementation is as shown in Figure 7, wherein packless solid box indicates PTRS, dotted line frame indicate A-TRS.

In this situation three, the method for elaborating to improve frequency domain track reference signal time domain density by taking PTRS as an example is such Mode reduces so that the frequency domain following range of complex tracking reference signal reaches requirement, while being utilized existing PTRS signal Expense.

It should also be noted that, the above-mentioned reference signal for temporal tracking and the reference signal for frequency domain tracking, it can To be used in combination with.And in practice, the two is usually used in combination with.

It should be noted that above-described embodiment on the time-frequency domain of target reference signal by increasing target following with reference to letter Number, it had both been reduced newly-increased with obtaining the complex tracking reference signal newly configured by the set-up mode of such track reference signal Track reference signal and caused by resource expense, in turn ensure that newly-installed complex tracking reference signal meets track demand, It ensure that the reliability and validity of 5G communication with this.
