Wherein, synchronizing signal refers to master sync signal/auxiliary synchronous signals (PSS/SSS, Primary Synchronization Signal/Secondary Synchronization Signal), MF master sync signals/MF it is auxiliary same Step signal (MF-PSS/MF-SSS, Multefire Primary Synchronization Signal/Multefire Secondary Synchronization Signal)。

Reference signal, refers to the channel shape of cell reference signals (CRS, Cell Reference Signal) and configuration State information reference signal (CSI-RS, Channel State Information-Reference Signal).

Here, the information that the PDSCH of broadcast is carried includes (SIB-MF1, System the Information Block of MF system information blocks 1 Multefire1)。

102nd, the base station maps the eDRS according to the information of the running time-frequency resource.

Base station according to the specifying information of the video resource, the occupancy resource size of such as eDRS, frequency domain position and time domain Position etc., the eDRS is mapped on corresponding running time-frequency resource.

103rd, the base station sends to terminal the running time-frequency resource for being mapped with the eDRS.

Wherein, the terminal in step 103 refers to the terminal for carrying out coverage enhancement user, is described for convenience, hereinafter referred to as eventually End.

104th, the terminal receives the eDRS that base station sends according to the information of running time-frequency resource.

A kind of method of enhanced detection reference signal mapping is the embodiment of the invention provides, for being operated in unauthorized frequency The communication system of section, according to the information of the running time-frequency resource for carrying enhanced detection reference signal, introduces more time-frequency moneys Source, by base station and terminal interaction, completes the transmission of eDRS to carry enhanced detection reference signal, realizes detection reference signal Repetition transmission on time-frequency, improves detection reference signal energy, realizes the coverage enhancement of detection reference signal.

Furthermore, it is understood that with reference to preceding method flow, when the information of the running time-frequency resource includes that the occupancy of the eDRS is provided During source size, the size of the occupancy resource depends on MPS process strengthens the rank of ability.

The maximal cover enhancing ability of system can be divided into multiple ranks, and each cell can be covered according to different maximums Lid enhancing ability is (for example, the maximal cover enhancing ability of system has { 8dB, 4dB, 0dB } three ranks.When being 0dB, cell is not Carry out coverage enhancement), it is determined that one group of running time-frequency resource of correspondence size is used to transmit eDRS.It is used to carry the running time-frequency resource of eDRS Size depend on MPS process strengthen ability.Here, the value of maximal cover enhancing ability is directed to the worst channel of covering, The coverage enhancement of other channels then be based on and worst channel before covering difference, accordingly remove the coverage enhancement that polishing is different. Therefore, the degree of the coverage enhancement of different channels is different, accordingly, it is necessary to the running time-frequency resource of different size and diverse location.

Wherein, when it is that existing synchronizing signal takes m times of running time-frequency resource that enhanced synchronizing signal takes running time-frequency resource, i.e., Existing synchronizing signal repeats transmission m+1 times, i.e., existing synchronizing signal strengthens m+1 times.

Wherein, first designated value can be any nonnegative number.

For the coverage enhancement of the synchronizing signal of coverage enhancement user, by transmitting enhanced synchronizing signal, realize existing The repetition transmission of synchronizing signal certain multiple.Wherein, enhanced synchronizing signal takes the size of resource depending on MPS process energy Power, i.e., the iterative transfer times of existing synchronizing signal depend on a coverage enhancement ability for cell.

The magnitude relationship of enhanced synchronizing signal and existing synchronizing signal is introduced for apparent explanation, below according to tool Body numeral is illustrated.It is { 0,4,8 } dB based on MPS process enhancing ability, the coverage enhancement of existing synchronizing signal is { 0,2.5,6.5 } dB.Accordingly, example 1, the possibility value of the maximum iterative transfer times of existing synchronizing signal is { 1,2,5 }, with Realize the different coverage enhancement ability of cell.The size that the enhanced synchronizing signal for introducing takes running time-frequency resource is existing synchronization Signal takes { 0, Isosorbide-5-Nitrae } times of running time-frequency resource, namely m is { 0, Isosorbide-5-Nitrae }.Example 2, the maximum iterative transfer times of existing synchronizing signal Possibility value be { 1,2,4.5 }.The size that the enhanced synchronizing signal for introducing takes running time-frequency resource is existing synchronizing signal { 0,1,3.5 } times of running time-frequency resource, namely m are taken for { 0,1,3.5 }.Example 3, existing synchronizing signal maximum iterative transfer times For { 1,2,4 } is secondary.The enhanced synchronizing signal for introducing takes the size of running time-frequency resource for existing synchronizing signal takes time-frequency money { 0,1,3 } in source times, namely m is { 0,1,3 }.Example 4, the possibility value of the maximum iterative transfer times of existing synchronizing signal is { 1,1.5,4.5 }.The enhanced synchronizing signal for introducing takes the size of running time-frequency resource for existing synchronizing signal takes time-frequency money { 0,0.5,3.5 } in source times, namely m is { 0,0.5,3.5 }.It is corresponding, according to the example above, when assuming that coverage enhancement is to be based on (i.e. existing synchronizing signal has 4 OFDM (Orthogonal Frequency of occupancy altogether for existing PSS/SSS and MF-PSS/SSS Division Multiplexing, OFDM) symbol), the OFDM symbol number that enhanced synchronizing signal takes is designated as N, then have the value of N in N=4*m, i.e. example 1 for { 0,4,16 }, and the value of N is { 0,4,14 } in example 2, and the value of N is in example 3 { 0,4,12 }, the value of N is { 0,2,14 } in example 4.When assuming that coverage enhancement is based on existing MF-PSS/SSS or PSS/ SSS (i.e. existing synchronizing signal have altogether occupancy 2 OFDM symbols), then in example 1, example 2, example 3, example 4, the value of N be respectively 0,2, 8 }, { 0,2,7 }, { 0,2,6 }, { 0,1,7 }.

As shown in Fig. 2 giving the existing synchronization based on 4-OFDM symbols (OFDM symbol symbol is identified in figure) The coverage enhancement of signal (legacy Sync).That is, by existing PSS/SSS and MF-PSS/MF-SSS, N- symbols are obtained Enhanced synchronizing signal (e-Sync).For the convenience illustrated, it is assumed that the transmission bandwidth of enhanced synchronizing signal is 6 PRB (Physical Resource Block, Physical Resource Block) is right, and Fig. 2 gives one of PRB, and to interior schematic diagram, (other 5 It is individual the same).In figure, each sub-box refers to a resource particle (Resource Element, RE).

It should be noted that the mapping graph of follow-up e-Sync is based on the legacy of 4-OFDM symbols in the embodiment of the present invention Sync (i.e. legacy Sync include PSS/SSS and MF-PSS/MF-SSS) is illustrated, and is subsequently no longer repeated one by one.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced synchronizing signal, the running time-frequency resource Information including the eDRS frequency domain position when, the frequency domain position is used to indicate the enhanced synchronizing signal in system band Frequency domain position in width, the enhanced synchronizing signal may be located at 6, the center PRB of system bandwidth to upper, it is also possible to be located at Non-central 6 PRB of system bandwidth are to upper.

4 OFDM symbols are taken based on existing synchronizing signal (legacy Sync), enhanced synchronizing signal (e-Sync) accounts for N number of OFDM symbol is used, based on Fig. 3 (a)-Fig. 3 (d) to the frequency domain position relation of enhanced synchronizing signal and existing same stairstep signal It is further described.As shown in Fig. 3 (a), Fig. 3 (b), enhanced synchronizing signal is located at 6, system bandwidth center PRB to interior, The enhanced synchronizing signal of Fig. 3 (a) N- symbols (Transmission in different Transmission Time Intervals from existing synchronizing signal Time Interval, TTI), a part of enhanced synchronizing signals of Fig. 3 (b) are with existing synchronizing signal in same TTI.As schemed Shown in 3 (c), Fig. 3 (d), enhanced synchronizing signal may be located on non-central 6 PRB of system bandwidth to interior.Fig. 3 (c) N- are accorded with Number enhancing synchronizing signal be located at where existing synchronizing signal in multigroup non-central 6 PRB in TTI, Fig. 3 (d) N- symbols Multigroup non-central 6 PRB of the enhancing synchronizing signal in multiple difference TTI is to 6, Nei He centers PRB to interior.Wherein, Fig. 3 In (a)-Fig. 3 (d) when enhanced synchronizing signal is divided into some, illustrated with Part1,2,3 ....Need explanation It is that enhanced synchronizing signal is not limited to the example of Fig. 3 (a)-Fig. 3 (d) with the relation of existing synchronizing signal, there can be more sides Formula.

It should be noted that for other signals or channel in eDRS, such as enhanced Physical Broadcast Channel is wide with existing The position relationship for broadcasting channel can also be mapped according to the position relationship in Fig. 3 (a)-Fig. 3 (d) example, here no longer one by one Picture explanation.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced synchronizing signal, the running time-frequency resource Information including the eDRS time-domain position when, the time-domain position is used to indicate the time domain position of the enhanced synchronizing signal Put, the enhanced synchronizing signal can take any one OFDM symbol, it is also possible to take the first orthogonal frequency division multiplexing specified Use symbol.

Wherein, first OFDM symbol specified represents the symbol for not containing cell reference signals (CRS) Or do not contain the symbol of Physical Downlink Control Channel (PDCCH) or do not contain cell reference signals and Physical Downlink Control Channel Symbol.

Enhanced synchronizing signal is transmitted in any one OFDM symbol, and the RE for referring to enhanced synchronizing signal can be with Any one signal in puncture (replacement) system.Enhanced synchronizing signal is carried out in the OFDM symbol for do not contain CRS Transmission, other signals that the RE for referring to enhanced synchronizing signal can be with puncture in addition to CRS.Enhanced synchronizing signal exists Do not contain and be transmitted in the OFDM symbol of PDCCH, i.e., enhanced synchronizing signal can be with puncture in addition to PDCCH other Signal.Enhanced synchronizing signal is transmitted in the OFDM symbol for not containing CRS and PDCCH, i.e., enhanced synchronizing signal Can be with other signals of puncture in addition to CRS and PDCCH.

Wherein, the cell reference signals (CRS) at least include existing cell reference signals.Or, the cell reference Signal includes existing cell reference signals and enhanced cell reference signals.

Wherein, the Physical Downlink Control Channel (PDCCH) at least includes existing Physical Downlink Control Channel.Or, institute Stating Physical Downlink Control Channel includes existing Physical Downlink Control Channel and enhanced Physical Downlink Control Channel.

In order to the time-domain position further to enhanced synchronizing signal is described in detail, below in conjunction with Fig. 4 (a)-Fig. 4 E () and Fig. 5 (a)-Fig. 5 (c) takes OFDM symbol and carries out illustrated exemplary to enhanced synchronizing signal.Wherein, Fig. 4 (f), Fig. 5 D () is respectively the legend of Fig. 4 (a)-Fig. 4 (e), Fig. 5 (a)-Fig. 5 (c).

In Fig. 4 (a)-Fig. 4 (e), enhanced synchronizing signal puncture CRS, but not puncture PDCCH.Fig. 4 (a), The existing synchronizing signal of Fig. 4 (b), Fig. 4 (c) strengthens 4 times；The existing synchronizing signals of Fig. 4 (d) strengthen 4.5 times；The existing synchronous letters of Fig. 4 (e) Number enhancing 5 times.

In Fig. 5 (a)-Fig. 5 (c), the transmission of enhanced synchronizing signal not puncture CRS and PDCCH, and it is enhanced same Step signal is not collided with each other (i.e. enhanced synchronizing signal is mapped in the OFDM symbol without CRS) with the transmission of CRS.Fig. 5 (a) Existing synchronizing signal strengthens 4 times；The existing synchronizing signals of Fig. 5 (b) strengthen 4.5 times；The existing synchronizing signals of Fig. 5 (c) strengthen 5 times.

And for the convenience illustrated, in Fig. 4 (a)-Fig. 4 (e) and Fig. 5 (a)-Fig. 5 (c), enhanced synchronizing signal is only 6, the center of system bandwidth, PRB is transmitted to interior, and one of PRB is only gived in figure to interior schematic diagram (other 5 the same).In figure, each sub-box refers to a RE.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced Physical Broadcast Channel, the time-frequency When the information of resource includes the occupancy resource size of the eDRS, the occupancy resource size is used to indicate the enhanced physics It is n times that existing Physical Broadcast Channel takes running time-frequency resource that broadcast channel takes running time-frequency resource, and the value of n is the second designated value.

Wherein, it is that existing Physical Broadcast Channel takes running time-frequency resource when enhanced Physical Broadcast Channel takes running time-frequency resource At n times, i.e., existing Physical Broadcast Channel repeats transmission n+1 times, i.e., existing Physical Broadcast Channel strengthens n+1 times.

Wherein, second designated value can be any nonnegative number.

For the coverage enhancement of the Physical Broadcast Channel of coverage enhancement user, by transmitting enhanced Physical Broadcast Channel, Realize the repetition transmission of existing Physical Broadcast Channel certain multiple.Wherein, enhanced Physical Broadcast Channel takes the size of resource Depending on MPS process ability, i.e., the iterative transfer times of existing Physical Broadcast Channel depend on a coverage enhancement energy for cell Power.It is { 0,4,8 } dB, MF-PBCH correspondence enhancing { 0,4,8 } dB based on MPS process enhancing ability, then has the maximum of MF-PBCH Iterative transfer times can be the money of 6 times (n=5), 6.5 times (n=5.5), or 7 times (n=6), namely enhanced synchronizing signal Source size is 5 times of existing MF-PBCH, 5.5 times or 6 times.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced Physical Broadcast Channel, the time-frequency When the information of resource includes the frequency domain position of the eDRS, the frequency domain position is used to indicate the enhanced Physical Broadcast Channel Frequency domain position in system bandwidth, the enhanced Physical Broadcast Channel may be located at 6, the center physics money of system bandwidth Source block is to upper, it is also possible to which non-central 6 PRB positioned at system bandwidth are to upper.

Frequency domain position relation to enhanced MF-PBCH and existing MF-PBCH is further described.As enhanced MF- PBCH be located at system bandwidth 6, center PRB to it is upper when, enhanced MF-PBCH and existing MF-PBCH can not be same TTI or in same TTI.When enhanced MF-PBCH be located at system bandwidth non-central 6 PRB to it is upper when, enhanced MF- PBCH and existing MF-PBCH can not be in same TTI or in same TTI.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced Physical Broadcast Channel, the time-frequency When the information of resource includes the time-domain position of the eDRS, the time-domain position is used to indicate the enhanced Physical Broadcast Channel Time-domain position, the enhanced Physical Broadcast Channel can take any one OFDM symbol, it is also possible to take Second OFDM symbol specified.

Wherein, second OFDM symbol specified represents the symbol for not containing cell reference signals.

Wherein, the cell reference signals at least include existing cell reference signals.Or, the cell reference signals bag Include existing cell reference signals and enhanced cell reference signals.

It should be noted that when enhanced MF-PBCH is transmitted, if the OFDM symbol for carrying existing MF-PBCH is free of There is CRS, then enhanced MF-PBCH may map in the OFDM symbol without CRS；Or it is mapped to the OFDM symbols containing CRS On number, while puncture CRS.If containing CRS in the OFDM symbol for carrying existing MF-PBCH, enhanced MF-PBCH It is mapped to containing CRS, or the OFDM symbol without CRS.For the OFDM symbol containing CRS, can be in corresponding time-frequency Resource repeats transmission CRS, or does not transmit CRS.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced synchronizing signal and enhanced thing Reason broadcast channel, when the information of the running time-frequency resource includes the frequency domain position of the eDRS, if the enhanced synchronizing signal with The enhanced Physical Broadcast Channel in 6, the center of system bandwidth Physical Resource Block to being above transmitted, it is described enhanced Transmission priority of the synchronous transmission of signal priority higher than the enhanced Physical Broadcast Channel.

When transmission priority of the enhanced synchronous transmission of signal priority higher than the enhanced Physical Broadcast Channel When, system transmits enhanced synchronizing signal using all available resource priorities as far as possible, then just starts to send enhanced MF- PBCH.The transmission preferences of i.e. enhanced synchronizing signal are in enhanced MF-PBCH.

Furthermore, it is understood that with reference to preceding method flow, when the eDRS includes enhanced synchronizing signal and enhanced thing Reason broadcast channel, when the information of the running time-frequency resource includes the frequency domain position of the running time-frequency resource, if the enhanced synchronous letter Number with the enhanced Physical Broadcast Channel in 6, the center of system bandwidth Physical Resource Block pair or non-central 6 physical resources Block to being above transmitted, the transmission preferences of the enhanced synchronous transmission of signal priority and the enhanced Physical Broadcast Channel Level is identical.

When the enhanced synchronous transmission of signal priority and the transmission priority phase of the enhanced Physical Broadcast Channel Meanwhile, that is, refer to that system carries out parallel transmission to the transmission of enhanced synchronizing signal and enhanced MF-PBCH.

In order that the transmission situation of e-Sync and enhanced MF-PBCH is easier to understand, based on different existing synchronizations Signal enhancing multiple and existing MF-PBCH intensification factors, by Fig. 6 (a)-Fig. 6 (c), Fig. 7 (a), Fig. 7 (b), Fig. 8 (a), figure The mapping of 8 (b), Fig. 9 (a), Fig. 9 (b) to e-Sync and enhanced MF-PBCH carries out citing signal.Wherein, Fig. 6 (d), Fig. 7 C (), Fig. 8 (c), Fig. 9 (c) are respectively Fig. 6 (a)-Fig. 6 (c), Fig. 7 (a)-Fig. 7 (b), Fig. 8 (a)-Fig. 8 (b), Fig. 9 (a)-Fig. 9 The legend of (b).And for the convenience illustrated, Fig. 6 (a)-Fig. 6 (c), Fig. 7 (a), Fig. 7 (b), Fig. 8 (a), Fig. 8 (b), Fig. 9 A in (), Fig. 9 (b), enhanced synchronizing signal is only transmitted in 6, the center of system bandwidth PRB to interior, and is only given in figure One of PRB is to interior schematic diagram (other 5 the same).

In Fig. 6 (a)-Fig. 6 (c), existing synchronizing signal strengthens 4 times, and existing MF-PBCH strengthens 6 times.Fig. 7 (a), In Fig. 7 (b), existing synchronizing signal strengthens 4.5 times, and existing MF-PBCH strengthens 6 times.It is existing same in Fig. 8 (a), Fig. 8 (b) 4.5 times of signal enhancing of step, and existing MF-PBCH strengthens 7 times.In Fig. 9 (a), Fig. 9 (b), existing 5 times of synchronizing signal enhancing, and Existing MF-PBCH strengthens 6.5 times.

Wherein, the eMF-PBCH in figure divides during for some, is identified by eMF-PBCH#1,2,3,4 ....

It should be noted that in illustrated above, removing the TTI containing existing DRS, other contain the TTI of eDRS So that according to existing pattern, non-central 6 PRB in a TTI are transmitted to interior.Therefore, for transmitting the time-frequency of eDRS Resource can both be obtained only by time domain extension, it is also possible to obtain (i.e. non-central 6 PRB) only by frequency domain expansion, Can be extended by time domain and frequency domain simultaneously and obtained.Wherein, the TTI containing eDRS can also simultaneously contain existing DRS.

Furthermore, it is understood that with reference to preceding method flow, when the information of the running time-frequency resource include the running time-frequency resource when During the position of domain, the eDRS is fixed with the relative time relationship of existing DRS；Or flexibly changed according to time criterion.

Wherein, the time criterion includes listem-before-talk mechanism successful time point and eDRS pot lifes section.

It should be noted that the DRS coverage enhancements in order to realize coverage enhancement user, the transmission time of eDRS is likely larger than 1 TTI.

Relative time relationship between existing DRS and eDRS can be fixed.For example, existing DRS is always first sent, then Send eDRS, also, in view of there is other data channels to need to send, existing DRS always sends in TTI0 or TTI5, then TTIs of the eDRS behind TTI0 or TTI5 is transmitted, it is seen that the schematic diagram as shown in Figure 10.Further illustrate, if There is no the specific data of user, existing DRS may begin at any one TTI.

Relative time relationship between existing DRS and eDRS is flexibility and changeability, can be according to the success of listem-before-talk mechanism Time point and the eDRS pot lifes section time criterion flexibly change.But in order to reduce the blind check complexity of user, The relative time relationship of existing DRS and eDRS can be limited.It is existing as shown in Figure 11 (a), Figure 11 (b), Figure 11 (c), Figure 11 (d) The relative time relationship for having DRS and eDRS can become, depending on LBT successful time points.Figure 11 (a), Figure 11 (b), Figure 11 (c), In Figure 11 (d), it is assumed that eDRS occupies 4 TTI in time domain, existing DRS takes 1 TTI, and can only be in TTI#0 and TTI#5 Send.

In Figure 11 (a), eNB proceeds by downlink transfer after LBT successes from TTI#1.Because existing DRS can only be TTI#0/5 sends, and eDRS is just advanceed to TTI#1-#4 and is transmitted.

In Figure 11 (b), eNB proceeds by downlink transfer after LBT successes from TTI#2.Then the parts of eDRS 2- the 4th It is placed on TTI#2-#4 and is first transmitted, then send existing DRS, retransmits the part 1 of eDRS.

In Figure 11 (c), eNB proceeds by downlink transfer after LBT successes from TTI#3.Then the parts of eDRS 3- the 4th It is placed on TTI#3-#4 and is first transmitted, then send existing DRS, retransmits the part 1 and part 2 of eDRS.

In Figure 11 (d), eNB proceeds by downlink transfer after LBT successes from TTI#4.Then the parts of eDRS the 4th are placed on First it is transmitted on TTI#4, then sends existing DRS, retransmits the part 1-third portion of eDRS.

Furthermore, it is understood that with reference to preceding method flow, after terminal receives eDRS, because the phase of eDRS and existing DRS To the flexible change of time relationship, therefore after terminal receives eDRS, in addition it is also necessary to carry out blind check to decode the eDRS.Therefore The alternatively possible implementation of the embodiment of the present invention additionally provides following methods flow, as shown in figure 12, performs in step After 104, including：

105th, the eDRS received described in the terminal-pair carries out blind check, to decode the eDRS.

Based on above example, it is necessary to explanation, coverage enhancement user is in the configuration of detection reference signal time of measuring Existing DRS is received in (DMTC, Discovery Signals Measurement Timing Configuration) window.And Base station can send eDRS within DMTC, or eDRS is sent outside DMTC.It should be noted that when base station is outside DMTC When sending eDRS, coverage enhancement user need not merge the existing DRS within DMTC, can be based only on the eDRS outside DMTC and enter Row decoding.
