For convenience of explanation, in following introduction, the multiple subcarriers of NB-IoT system mapped are known as NB-IoT The multiple subcarriers of NR system mapped are known as NR subcarrier by subcarrier, and by the multiple subcarriers of LTE system mapped Referred to as LTE subcarrier.

In the following, being illustrated to the relationship between NR subcarrier, LTE subcarrier and NB-IoT subcarrier.

Bandwidth of the carrier wave of one LTE system on frequency domain can for 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and Any one in 20MHz, every kind of different bandwidth includes respectively may be used on frequency domain in several PRB, such as above-mentioned LTE system The PRB for including in the bandwidth of energy is respectively 6 PRB, 15 PRB, 25 PRB, 50 PRB, 75 PRB and 100 PRB, that is, When the carrier wave of LTE system is 1.4MHz, the carrier wave of the LTE system includes 6 PRB, when the carrier wave of LTE system is 3MHz When, which includes 15 PRB, and so on.Referring to FIG. 3, include 12 subcarriers in a PRB on frequency domain, In, each subcarrier spacing can be 15kHz, it is of course also possible to use other subcarrier spacings, such as 3.75kHz, 30kHz, 60kHz or 120kHz subcarrier spacing, this is not restricted.In the time domain, a PRB includes 14 orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol, wherein 14 OFDM symbols corresponding one A subframe.One PRB is made of the RB of the RB of adjacent even timeslots slot and odd number slot.Therefore, when the carrier wave of LTE system When for 1.4MHz, the carrier wave of the LTE system includes 72 subcarriers, and when the carrier wave of LTE system is 3MHz, which includes There are 180 subcarriers, and so on.In LTE system, the least resource granularity for carrying out data transmission can be resource element Plain (resource element, RE), as shown in Figure 3, a RE correspond to 1 OFDM symbol in the time domain, right on frequency domain Answer 1 subcarrier.

When NR system and LTE system share carrier resource, the not used resource of LTE system is can be used in NR system.Such as figure Example shown in 4A, LTE system can transmit LTE system when carrying out data transmission on the carrier wave of a LTE system in subframe The channel of system.For example, in a radio frame, LTE system can be in the 1st subframe, the 2nd subframe, the 3rd subframe, the 5th The channel of LTE system is transmitted in subframe, the 6th subframe, the 8th subframe, the 9th subframe and the 10th subframe.Wherein, LTE system The channel of system includes at least one in PDSCH, PDCCH and CRS.For another example may be not in the 4th subframe and the 7th subframe It maps Physical Downlink Shared Channel (physical downlink shared control channel, PDSCH), at the 4th Subframe and the 7th subframe show Physical Downlink Control Channel (the physical downlink control for having penetrated LTE Channel, PDCCH) and cell reference signals (cell reference signal, CRS), then, and NR system and LTE system When shared carrier resource, the not used resource of LTE system in the 4th subframe and the 7th subframe is can be used in NR system, this does not make Resource can be other resources in addition to the resource that PDCCH and CRS signal occupies.

Below for convenience of description, the carrier wave of LTE system is known as LTE carrier wave, the carrier wave of NR system is known as NR carrier wave.

When NR system and LTE system share carrier resource, the network equipment of NR system can be reserved for terminal device notice Resource, the reserved resource can be the resource that LTE system uses.The network equipment of NR system can notify LTE for terminal device The resource that system uses, the network equipment of NR system can by the frequency domain position of the central subcarrier of LTE carrier wave by broadcast or The mode of person's unicast is notified to the terminal device of the NR system, for example, example as shown in Figure 4 B, in a radio frame, LTE System can be in the 1st subframe, the 2nd subframe, the 3rd subframe, the 5th subframe, the 6th subframe, the 8th subframe, the 9th son The channel of LTE system is transmitted in frame and the 10th subframe.Wherein, LTE system is possible in the 4th subframe and the 7th subframe PDCCH and PDSCH are not mapped, are shown in the 4th subframe and the 7th subframe and have been penetrated CRS, in the example depicted in fig. 5, NR system The network equipment number of the corresponding NR subcarrier of the central subcarrier of the LTE carrier wave can be notified using S bit, S is Positive integer, for example, can be 14, and by the bandwidth of LTE carrier wave, the port number of LTE CRS, LTE CRS offset notify to The terminal device of NR system, the terminal device for NR system determine which RE of NR system is reserved resource, thus, NR system The terminal device of system can map the channel of NR system in the resource in the 4th subframe and the 7th subframe in addition to these RE resources, That is the terminal device of NR system thinks that these RE resources are not used in the channel of mapping NR system.In a kind of possible design, NR The network equipment of system to the terminal device of NR system notice LTE carrier wave central subcarrier when, can as unit of subcarrier into Row notice, the i.e. number of the corresponding NR subcarrier of central subcarrier of notice LTE carrier wave, the Serial Number Range of corresponding NR subcarrier For (0 arrives SC_max×N_RB×N_SCOr 0 to SC_max×N_RB×N_SC- 1), SC_maxIt is the maximum subcarrier that 6GHz or less frequency range is supported The ratio of 60kHz and 15kHz subcarrier spacing, such as SC_maxEqual to 4；N_RBCorrespond to subcarrier spacings maximum support PRB number, such as N_RBIt is 275；N_SCRefer to the sub-carrier number for including in a PRB, such as N_SCIt is 12.For convenience of description, will preset Range: 0 arrives SC_max×N_RB×N_SCOr 0 to SC_max×N_RB×N_SC- 1, the referred to as advice range of the central subcarrier of LTE carrier wave. It include PRB0 to PRB274 totally 275 PRB, and the son of the PRB0 of NR carrier wave in the carrier wave if the bandwidth of NR carrier wave is 200MHz Carrier wave 0 is aligned with the frequency domain position of the central subcarrier of LTE carrier wave or the subcarrier 11 of the PRB274 of NR carrier wave and LTE carrier wave Central subcarrier frequency domain position alignment, as shown in Figure 5A, then LTE system can be to the network equipment or terminal of the NR system Equipment notifies the frequency domain position of the central subcarrier of LTE carrier wave.

When the bandwidth of NR carrier wave is 200MHz, includes PRB0 to PRB274 totally 275 PRB in the carrier wave, wrapped in each PRB Include 12 subcarriers, but when the subcarrier 0 of the frequency domain position of the central subcarrier of LTE carrier wave and NR carrier wave PRB0 are misaligned, such as Shown in Fig. 5 B, the frequency domain position of the central subcarrier of LTE carrier wave deviates to the left relative to the subcarrier 0 of NR carrier wave or LTE carrier wave The frequency domain position of central subcarrier deviated to the right relative to the subcarrier 11 of NR carrier wave PRB274, at this point, the center of LTE carrier wave Subcarrier is not then in advice range, and the network equipment of NR system is without the middle center of the terminal device of normal direction NR notice LTE carrier wave The frequency domain position of carrier wave.

To solve the network equipment of NR system without the central subcarrier of the terminal device of normal direction NR system notice LTE carrier wave The problem of frequency domain position, can expand the advice range of the central subcarrier of LTE carrier wave in the embodiment of the present application.

In a kind of possible embodiment, due to the carrier bandwidths maximum of LTE system can be 20M, i.e. LTE system most It include 100 PRB, when there is situation as shown in Figure 5 B, the frequency domain position of the central subcarrier of LTE carrier wave is relative to NR more The multidirectional left avertence of subcarrier 0 of the PRB0 of carrier wave 60kHz moves the PRB of 50 15kHz, i.e., the subcarrier or LTE of 600 15kHz Subcarrier number N of the frequency domain position of the central subcarrier of carrier wave relative to NR carrier wave 60kHz_RB×N_SC- 1 deviates to the right 50 The PRB of 15kHz, i.e. 600 15kHz subcarriers therefore can be corresponding in NR carrier wave by the central subcarrier of LTE carrier wave The advice range of subcarrier expand as -599 to SC_max×N_RB×N_SC+ 600, or -599 to SC_max×N_RB×N_SC+ 599, this When, the network equipment of NR system can still notify the frequency domain position of the central subcarrier of LTE carrier wave using S bit, for example, The value of S can be 14, then the value of 14bit instruction, which subtracts 599, can be obtained by the corresponding NR load of LTE carrier center subcarrier Wave number, and bandwidth, CRS port number, the CRS offset of LTE carrier wave is combined to determine the position RE that the CRS of LTE carrier wave occupies jointly It sets, so that the network equipment and terminal device of NR system are not used in data transmission on the corresponding position RE.

In a kind of possible embodiment, the central subcarrier advice range of LTE carrier wave can expand as 0 to (4+2+1+ 1) * 275*12, and notify using 16 bits the frequency domain position of the central subcarrier of the LTE carrier wave.In this way, NR carrier wave can be with Be divided into the NR carrier wave of the 200MHz of 60kHz comprising a sub- intercarrier, a sub- intercarrier be divided into 30kHz 100MHz NR Carrier wave and a sub- intercarrier are divided into the NR carrier wave of the 50MHz of 15kHz, and the bandwidth using remaining 50MHz includes LTE carrier wave Central subcarrier frequency domain position beyond NR carrier wave starting frequency domain position and NR carrier wave the last one PRB boundary where Frequency domain position situation thereby may be ensured that the network equipment of NR system can be accurately to NR system as shown in Fig. 5 C or Fig. 5 D The frequency domain position of the central subcarrier of the terminal device notice LTE carrier wave of system.

It should be noted that if not mapping any LTE channel on LTE carrier wave, then LTE system can be used in NR system Entire carrier wave, at this point, LTE carrier wave is NR carrier wave, LTE subcarrier is NR subcarrier.

The carrier wave of NB-IoT system is typically deployed on LTE carrier wave.Effective band of the carrier wave of NB-IoT system on frequency domain Width is M LTE subcarrier, and the value of M can be 12, it is of course also possible to use other values, this is not restricted, when taking for M When value is 12, effective bandwidth of the carrier wave of NB-IoT system on frequency domain is the width of a PRB.For convenience of description, below will The carrier wave of NB-IoT system is known as NB-IoT carrier wave.

There are three types of the relationships of deployment between NB-IoT carrier wave and a LTE carrier wave, are respectively as follows: band internal schema (inband, IB) Deployment, protection band module (guardband, GB) deployment, band external schema (outband, OB) are disposed.Referring to FIG. 6, being NB-IoT The schematic diagram of three kinds of deployment way of system.By taking LTE carrier bandwidths are 10MHz as an example, then LTE carrier wave includes 50 on frequency domain PRB, respectively PRB0~PRB49.When NB-IoT system uses IB deployment way, one of NB-IoT carrier occupancy LTE carrier wave PRB；When NB-IoT system uses GB deployment way, NB-IoT carrier wave is deployed in the protection bandwidth of the carrier wave of LTE system；NB- IoT system use OB deployment way when, NB-IoT carrier wave is deployed in except LTE carrier wave, that is, NB-IoT carrier wave on frequency domain and LTE carrier wave is not overlapped.

By the frequency spectrum refarming of LTE system to NR system in use, the carrier wave of LTE system, that is, NR system carrier wave, NR There may be a NR-IoT carrier wave to dispose in carrier wave, i.e., NR carrier wave and NB-IoT carrier wave share carrier resource.Here with NB- The deployment of IoT system is that for IB mode is disposed, the method in the embodiment of the present application is described in detail.

In a kind of possible embodiment, the specific implementation of step 201 is as follows:

1) frequency domain information for the NB-IoT carrier wave that the network equipment that the network equipment of NR system receives NB-IoT system is sent.

Illustratively, the network equipment of NR system can pass through X2/Xn mouthful of X2/Xn interface or enhancing and NB-IoT system The network equipment, for example, the base station NB-IoT, the frequency domain information of interaction NB-IoT carrier occupancy.A kind of optional mode is the base station NB By X2/Xn mouthfuls or X2/Xn mouthfuls of enhancing send solicited message to the network equipment of NB-IoT system, and the solicited message is for requesting The frequency domain information of the carrier wave of NB-IoT, the network equipment of NB-IoT system is after receiving the solicited message, then by NB-IoT's The frequency domain information of carrier wave is sent to the network equipment of NR system.Alternatively, the network equipment of NB-IoT system is also possible to disposing After the carrier wave of NB-IoT, frequency domain information or the period of the carrier wave of the NB-IoT are actively sent to the network equipment of NR system Property sends the frequency domain information of the carrier wave of the NB-IoT to the network equipment of NR system.It is of course also possible to use other modes obtain The frequency domain information of the carrier wave of the NB-IoT, this is not restricted.Wherein, in the embodiment of the present application, the frequency domain of the carrier wave of NB-IoT Information can also be known as the frequency domain information of the carrier wave of NB-IoT system.

In a kind of possible embodiment, the network equipment of NR system and the network equipment interaction NB- of NB-IoT system When the frequency domain information of IoT carrier occupancy, which can be the absolute frequency point number and NB-IoT carrier wave of NB-IoT carrier wave Offset information of the carrier center relative to absolute frequency point number.It is opposite to the carrier center of absolute frequency point number and NB-IoT carrier wave below It is introduced in the offset information of absolute frequency point number.

In the frequency range of LTE, LTE carrier wave is searched for for the ease of the terminal device of LTE system, the grid based on 100kHz is true The carrier center position for determining LTE carrier wave, since NB-IoT carrier wave and LTE carrier wave share the frequency domain resource of LTE carrier wave, The carrier center position of NB-IoT carrier wave is determined based on the grid of 100kHz.In addition, if by the frequency spectrum of LTE system Refarming to NR system in use, when NR system and NB-IoT system share carrier resource, can be based on the grid of 100kHz Determine the carrier center of NR carrier wave.

In frequency range, each grid corresponds to an absolute frequency point number, and 16 bits are used in the corresponding frequency range of LTE carrier wave (bit) Absolute Radio Frequency Channel number (absolute radio frequency channel number, EARFCN) field is come Indicate the absolute frequency point number of the carrier center of LTE carrier wave.For example, the EARFCN calculating of LTE ascending resource can be regular as follows: F_UL =F_{UL_low}+0.1(N_UL–N_Offs-UL), wherein F_ULFor the EARFCN of LTE ascending resource, F_ULFor the center frequency of LTE ascending resource Point, 0.1 is the grid size 100kHz, N of LTE carrier wave uplink and downlink resource_Offs-ULFor bandwidth described in LTE carrier wave ascending resource The corresponding EARFCN of low-limit frequency.Table 1 is bandwidth and uplink and downlink resource grid size relation table.Therefore, pass through absolute frequency point number Value can determine a unique absolute frequency value.

Table 1

NB-IoT carrier center includes: deviant ± 7.5kHz, ± 2.5kHz relative to the offset information of absolute frequency point number In a value, the value is for indicating offset of the NB-IoT carrier center relative to absolute frequency point number.Wherein in NB-IoT carrier wave The heart is optionally, when not including this information, to indicate the carrier wave of NB-IoT carrier wave relative to the offset information of absolute frequency point number Center absolute frequency corresponding with the absolute frequency point number is completely coincident.

The network equipment of NR system can be according to absolute frequency point number and NB-IoT carrier center relative to absolute frequency point number Offset information determine the frequency domain information of NB-IoT carrier wave.

In alternatively possible embodiment, the network equipment interaction of the network equipment and NR system of NB-IoT system When the frequency domain information of NB-IoT carrier occupancy, which can be the subcarrier 0 or other subcarrier phases of NB-IoT carrier wave For the offset information of the central subcarrier of NR carrier wave.

With above-mentioned frequency domain information be NB-IoT carrier wave subcarrier 0 relative to NR carrier wave central subcarrier offset information For:

A kind of optional mode are as follows: PRB of the subcarrier 0 in NR system in the frequency domain information comprising NB-IoT carrier wave is compiled Number and subcarrier number, wherein the range of PRB number can be 0~to SC_max×N_RB- 1 or 0 arrives (∑ SC_i+1)×N_RB- 1, Middle SC_maxIt is the ratio of maximum subcarrier 60kHz and 15kHz subcarrier spacing that 6GHz or less frequency range is supported, such as SC_maxIt is equal to 4；N_RBCorrespond to the PRB number of subcarrier spacings maximum support, such as N_RBIt is 275, ∑ SC_iIndicate 6GHz or less frequency range branch The sum of the ratio of each sub-carrier and 15kHz subcarrier spacing held, for example, 60kHz and 15kHz subcarrier spacing ratio, The sum of ratio and the ratio of 15kHz and 15kHz subcarrier spacing of 30kHz and 15kHz subcarrier spacing, i.e. 4+2+1；Son carries The range of wave number can make 0~11.Such as the PRB number in the first information including is 30, subcarrier number 0, then it represents that 1st subcarrier (subcarrier 0) of NB-IoT system is located at the corresponding frequency domain position of the 1st subcarrier in the PRB30 of NR system It sets.

Another optional mode are as follows: son of the subcarrier 0 in NR system in the frequency domain information comprising NB-IoT carrier wave Carrier index information, the Serial Number Range of sub-carriers can be 0~4*275*12-1 or 0~8*275*12-1, for example, the frequency The subcarrier number for including in domain information is 359, if in NR system in a RB including 12 subcarriers, number is 359 Subcarrier be located at the 1st subcarrier in the PRB30 of NR system, then the frequency domain information indicates first of NB-IoT carrier wave Subcarrier is located at first subcarrier in the PRB30 of NR system.

Certainly, the network equipment of NB-IoT system and the frequency domain information of the network equipment of NR system interaction are also possible to other Form, in the embodiment of the present application with no restriction.

2) network equipment of NR system determines each of NB-IoT system according to the frequency domain information of the carrier wave of NB-IoT system The frequency domain position of subcarrier.

The frequency domain information of the carrier wave for the NB-IoT system that the network equipment of NR system obtains can be in the carrier wave of NB-IoT The corresponding frequency domain information of some specific subcarrier, which can be the network equipment and NB-IoT system of NR system The network equipment make an appointment, for example, the specific subcarrier is the central subcarrier of NB-IoT carrier wave, such as subcarrier 6 (subcarrier number of NB-IoT is from 0 to 11) or the specific subcarrier are the starting subcarrier (son of the carrier wave of NB-IoT system Carrier wave 0), it is of course also possible to be the frequency domain center of other subcarriers or NB-IoT carrier wave in other multiple subcarriers, This is not restricted.In the following description, the frequency domain letter of the carrier wave of the NB-IoT system obtained with the network equipment of NR system For breath is the corresponding frequency domain information of central subcarrier in the carrier wave of NB-IoT.

It should be noted that step 201 is not limited to above-mentioned specific implementation, those skilled in the art can also use it He mode realizes that this is not restricted.

In a kind of possible embodiment, the corresponding resource of the carrier wave of NB-IoT system is not whole by NB-IoT system It occupies, for example, NB-IoT system may be only on certain several time-domain position, such as a few a subframes, in the NB-IoT system The channel of NB-IoT system is had mapped on the corresponding frequency domain position of carrier wave, therefore, in order to make full use of NB-IoT system to be not used Carrier resource, the method for the embodiment of the present application further include:

The network equipment of step 202:NR system determines the time-domain information that the channel in NB-IoT system is mapped to.

In the embodiment of the present application, the time-domain information include NB-IoT system channel occupancy sub-frame information or this when Domain information includes the OFDM symbol information that the channel of NB-IoT system occupies in subframe or the time-domain information includes NB-IoT system The sub-frame information of the channel occupancy of system and the OFDM symbol information occupied in subframe.

In the following, the channel of NB-IoT system is introduced.

NB-IoT system includes following four kinds of channels: narrowband Physical Broadcast Channel (narrowband physical Broadcast channel, NPBCH), it is narrow band sync channel (NB-IoT synchronization channel, NSCH), narrow Band Physical Downlink Control Channel (NB-IoT physical downlink control channel, NPDCCH) and protenchyma It manages DSCH Downlink Shared Channel (NB-IoT physical downlink shared channel, NPDSCH), wherein NSCH includes Narrowband primary synchronization channel (NB-IoT primary synchronization channel, NPSCH) and narrowband auxiliary synchronization channel (NB-IoT secondary synchronization channel, NSSCH).

Transmission narrowband reference signal (NB-IoT is required in the channel in addition to NSCH channel of each NB-IoT system Reference signal, NRS), NB-IoT primary synchronization signal (NB-IoT primary synchronization signal, NPSS it) is carried by NPSCH, secondary synchronization signal (the NB-IoT secondary synchronization of NB-IoT Signal, NSSS) it is carried by NSSCH, the period of NPSS is 10ms, and the period of NSSS is 20ms.

As shown in fig. 7, including 8 system-frame (system in each block of information (block) of NB-IoT system Frame, SF), it is referred to as radio frames.Each SF includes 10 subframes, and each subframe includes 2 time slots, a time slot For 0.5ms.NPBCH and transmission NPSS is mapped in each SF, wherein NPBCH occupies the 1st subframe of each SF, That is subframe 0, NPSS occupy the 4th subframe of each SF, i.e. subframe 5.NSSS occupies the last one subframe of every two SF, i.e., Subframe 9.A subframe of NSSS is not transmitted in the remaining subframe (subframe 1-4 and subframe 6-8) and every two SF of each SF In, select one or more subframe to map NPDCCH and NPDSCH.

Since NB-IoT system deployment is on the carrier wave of LTE system, LTE system may map object in each subframe It manages down control channel (physical downlink control channel, PDCCH), usual PDCCH is occupied in the time domain It is any one or more in preceding 3 OFDM symbols of one subframe, therefore, when NB-IoT system is disposed by the way of IB When, in order to avoid generating interference, the starting OFDM of the NPDCCH and NPDSCH of NB-IoT system between the PDCCH of LTE system After the OFDM symbol that the PDCCH that symbol is located at LTE system is occupied, the starting OFDM symbol of the NPDCCH and NPDSCH pass through The system message broadcast (system information block, SIB) of NB-IoT determines, includes LTE system in the SIB PDCCH occupies OFDM symbol number, and value can be 1 or 2 or 3, such as: the SIB instruction LTE system of NB-IoT system broadcasts It is 1 that PDCCH, which occupies OFDM symbol number, then it represents that the 1st OFDM symbol, i.e. symbol of the subframe that the PDCCH of LTE system is occupied 0, correspondingly, NPDCCH and NPDSCH mapping starting OFDM symbol then mapped since the 2nd OFDM symbol of subframe, i.e., from Symbol 1 starts to map.

It is of course also possible to the deployment way for NB-IoT system of making an appointment and the starting OFDM symbol of NPDCCH and NPDSCH Corresponding relationship, for example, when the deployment way of NB-IoT system be IB dispose when, then NPDCCH and NPDSCH starting OFDM symbol Number for the 4th OFDM symbol in subframe, it is similar to NPBCH channel mapping result shown in Fig. 7；When the deployment of NB-IoT system When mode is that GB or OB is disposed, then the starting OFDM symbol of NPDCCH and NPDSCH is the 1st OFDM symbol in subframe.When So, the starting OFDM symbol of NPDCCH and NPDSCH mapping can also be determined using other modes, this is not restricted.

For NPSS and NSSS signal, in order to avoid generating interference, NPSS and NSSS letter between the PDCCH of LTE system It number is mapped since the 4th OFDM symbol in subframe.

It should be noted that when the deployment way of NB-IoT system is that IB is disposed, since LTE system is carried in each LTE CRS can be all transmitted on wave, therefore, NPSS signal and NSSS signal in the RE resource that the CRS of LTE system is occupied, only mapping but Reality does not transmit signal on the RE, i.e. NPSS signal and NSSS signal is punched by the CRS of LTE system.In addition, in order to guarantee NPSS The sequence length of signal and NSSS signal is less than the prime number of 12*11, therefore the formation sequence length of NPSS/NSSS is 121, and 11 OFDM symbols that NPSS signal and NSSS signal occupy in the time domain, therefore NPSS signal and NSSS signal are in NB-IoT system 0~subcarrier of subcarrier 10 is only taken up on the corresponding frequency domain of the carrier wave of system, subcarrier 11 does not transmit signal, as shown in Figure 7.

For NPBCH, the mapping of the channel in the time domain is since the 4th OFDM symbol of subframe, and NB-IoT system 12 subcarriers of carrier wave all use.In addition, it is necessary to explanation, since NPBCH needs to carry necessary instruction information, because No matter the deployment scenario of the carrier wave of this NB-IoT system, do not mapped in the RE resource that the CRS of LTE system is occupied in NPBCH Data.

It should be noted that the NPDCCH of NB-IoT system and NPDSCH can be mapped in Fig. 7 except NPSS signal, In one or more SF except the subframe that NSSS signal and NPBCH are occupied.

In a kind of possible embodiment, the specific implementation of step 202 is as follows:

By the time-domain information that the channel of NB-IoT system is mapped in NB-IoT system, for example, NPSS signal, The information for the subframe that NSSS signal and NPBCH channel occupy in a SF, and, at least one in NPDCCH and NPDSCH is reflected The information for the starting OFDM symbol penetrated, be it is fixed, as shown in Figure 7.But the SF frame number of NR system may be with NB-IoT system SF frame number there is offset, and/or, the subframe numbers of NR system may exist with the subframe numbers of NB-IoT system to be deviated, therefore, Before the network equipment of NR system determines the time-domain information that each channel of NB-IoT system is mapped in NR system, NR system The network equipment of system can also determine the corresponding relationship of the subframe of NB-IoT system and NR system.

In a kind of possible embodiment, the network equipment of NR system sends inquiry to the network equipment of NB-IoT system and disappears Breath inquires the subframe numbers of the network equipment NB-IoT system within a certain period of time of NB-IoT system, then, the net of NB-IoT system Network equipment is then set to the network that the subframe numbers of the network equipment of NR system feedback NB-IoT system within the time are 1, NR system Standby to determine within the time, the subframe numbers of NR system are 0, then the network equipment of NR system determines the corresponding NB- of the subframe 0 of NR system The subframe 1 of IoT system, alternatively, also can be described as: within a certain period of time, the subframe of NR system is the son of 0, NB-IoT system Frame is 1.For the channel in NB-IoT system, the time-domain information and NB- mapped to by the channel in NB-IoT system The corresponding relationship of the subframe of IoT system and NR system, can determine time domain position of the channel in NB-IoT system in NR system It sets.

In alternatively possible embodiment, since every 10 subframes of NB-IoT system constitute a SF, then NB- Each subframe of IoT system can be described with the mode that SF and subframe combine.The network of the base station NB-IoT and NR system At least one information of equipment by X2/Xn mouthfuls or in the mutual System Frame Number of enhancing X2/Xn oral sex, subframe numbers information.For example, by SF Number (system frame number, SFN) be combined with subframe number, each SFN is corresponding with 0 to 9 subframes and compiles Number, SFN0, subframe 0 indicate that first subframe in first SF, SFN0, subframe 1 indicate second in first SF Subframe, and so on.For the subframe of NR system, also adopts and be described in a like fashion.In this way, the network when NR system is set It is standby send inquiry message to the network equipment of NB-IoT system after, the network equipment of the network equipment of NB-IoT system to NR system The SFN and subframe numbers of the NB-IoT system within the time are fed back, for example, the network equipment of NB-IoT system was fed back within the time The SFN of NB-IoT system is 0, subframe numbers 0, and then the network equipment of NR system determines that the SFN of NR system is within the time 1, subframe numbers 0, then the network equipment of NR system determines the SFN0 of the corresponding NB-IoT system of the SFN1 of NR system, subframe 0, subframe 0, also can be described as: within a certain period of time, the SFN of NR system is 1, subframe numbers 0, and the SFN of NB-IoT system is 0, subframe Number be 0.

After the network equipment of NR system determines the corresponding relationship of the subframe of NR system and the subframe of NB-IoT system, then really Determine the information of the subframe of mapping of each channel of NB-IoT system in NR system.

In the embodiment of the present application, due to the content difference that time-domain information includes, for example, the channel comprising NB-IoT system The sub-frame information of occupancy or the time-domain information include the OFDM symbol information that the channel of NB-IoT system occupies in subframe, or The sub-frame information of channel occupancy of the time-domain information comprising NB-IoT system and the OFDM symbol information occupied in subframe, because This, the network equipment of NR system determines the mode of time-domain position of each channel of NB-IoT system in NR system also not phase Together.It is then illustrated respectively for these three different time-domain informations below.

The first situation: the time-domain information includes that at least one in NPSS signal, NSSS signal and NPBCH accounts in the time domain The information of subframe.

Specifically, if the time-domain information includes the information for the subframe that NPSS signal occupies in the time domain, the subframe Information can for by time domain frame number and subframe numbers carry out corresponding subframe number after joint number.For example, frame number range is 0 ~1023, the range of subframe numbers is 0~9 in a frame, and after joint number, subframe number may range from 0~10239, then The network equipment of NR system is according to the corresponding relationship of the subframe of NR system and the subframe of NB-IoT system, for example, in some time Interior, the SFN of NR system is 1, subframe numbers 0, and the SFN of NB-IoT system is 0, subframe numbers 0 and the fixed mapping of NPSS signal The 5th subframe into each SF, i.e. subframe 4, then the network equipment of NR system determines that NPSS signal maps in NR system First subframe be respectively NR system SFN be 1 the 5th subframe, alternatively, determine NPSS signal mapped in NR system Subframe be the 5th subframe in each SF since the SFN of NR system is 1.

Similarly, the information for the subframe that NSSS signal and NPBCH are occupied in the time domain can also use similar with NPSS Mode determine.

Certainly, if the period of NPSS signal, NSSS signal and NPBCH be it is fixed, for example, NPSS signal and The period of NPBCH is 10ms, and the period of NSSS signal is 20ms, if the time-domain information that the network equipment of NR system determines includes The information for the subframe that NPSS signal, NSSS signal and NPBCH signal occupy in the time domain, then the network equipment of NR system can be with The information for only determining first subframe that NPSS signal, NSSS signal and NPBCH occupy in the time domain, can be believed by NPSS Number period and first subframe information determine NPSS signal occupy other subframes information, NSSS signal can be passed through Period and first subframe information determine NSSS signal occupy other subframes information, NPBCH signal can be passed through Period and first subframe information determine NPBCH signal occupy other subframes information.

If the time-domain information includes the subframe that NPSS signal, NSSS signal and NPBCH signal occupy in the time domain The information of information, the subframe that the network equipment of NR system determines is also possible to NPSS signal, NSSS signal and NPBCH in time domain The offset of the default subframe of first subframe and NR system of the NR system of upper occupancy, for example, the default subframe is NR system The 1st subframe, determine NPSS signal in the first subframe of NR system and the 1st son of NR system with the network equipment of NR system For the offset of frame, the network equipment of NR system according to the corresponding relationship of the subframe of NR system and the subframe of NB-IoT system, For example, within a certain period of time, the SFN of NR system is 1, subframe numbers 0, and the SFN of NB-IoT system is 0, subframe numbers 0, and Fixed the 5th subframe mapped in each SF of NPSS signal, i.e. subframe 4, determine that NPSS signal occupies NR system in the time domain First subframe be SFN be 1, subframe numbers 4, i.e., relative to the offset of the 1st subframe of NR system be 14 subframes.

In the first case, if being used for transmission the subframe of NPSS signal and being used for transmission the NSSS signal of NPSS signal Subframe relative positional relationship be pre-configured, then the son that NPSS signal occupies in the time domain can be only included in time-domain information The information of frame can determine the information for the subframe that NSSS signal occupies in the time domain by the relative positional relationship of the pre-configuration； Alternatively, the information for the subframe that NSSS signal occupies in the time domain can be only included in time-domain information, pass through the opposite of the pre-configuration Positional relationship can determine the information for the subframe that NPSS signal occupies in the time domain.Similarly, this method can also be applied to NPSS signal and NPBCH, or NSSS signal and NPBCH can also be applied to.

It is mapped in the remaining subframe in a SF due to NPDCCH and NPDSCH, the network equipment of NR system is also The sub-frame information of NPDCCH and NPDSCH mapping can be determined by the method for the sub-frame information of determining NPSS signal mapping, This is repeated no more.

Second situation: the starting OFDM symbol comprising at least one mapping in NPDCCH and NPDSCH in the time-domain information Information.

The starting OFDM symbol of NPDCCH mapping is the starting OFDM that NPDCCH maps in the subframe for be used for transmission NPDCCH Symbol.The starting OFDM symbol of NPDSCH mapping is the starting OFDM symbol that NPDSCH maps in the subframe for be used for transmission NPDSCH Number.For a subframe, it can be used for transmitting at least one in NPDCCH and NPDSCH in the subframe.

In the embodiment of the present application, the information of the starting OFDM symbol of NPDCCH and NPDSCH mapping can be its starting The number of OFDM symbol, since the NPDCCH and NPDSCH starting OFDM symbol mapped in each subframe is the 4th OFDM symbol Number, i.e. OFDM 3, and the subframe of NR system is aligned with the subframe of NB-IoT system, then the network equipment of NR system determines Starting OFDM symbol of the NPDCCH and NPDSCH in the subframe that NR system maps is OFDM 3.

In oneainstance, if the primary sign that NPSS signal, NSSS signal and NPBCH occupy in subframe is also fixed as 4th OFDM symbol, then the network equipment of NR system can also determine NPSS signal, NSSS signal and NPBCH in NR system Starting OFDM symbol in the subframe of mapping is the 4th OFDM symbol.

It should be noted that if NB-IoT system is other than comprising aforementioned five kinds of channels, when also including other channels, this when In domain information can also comprising other channels mapping starting OFDM symbol information, particular content can with NPDCCH and NPDSCH is identical, and details are not described herein.

The third situation: the time-domain information includes NPSS signal, NSSS signal and the NPBCH subframe occupied in the time domain The information of information and the starting OFDM symbol of NPDCCH and NPDSCH mapping.

The third situation is the combination of above-mentioned two situations, i.e., includes two parts content in the time-domain information, wherein every portion The description for being divided to the specific descriptions of content to please refer to aforementioned two kinds of situations, details are not described herein.

It should be noted that step 202 is not limited to above-mentioned specific implementation, those skilled in the art can also use it He mode realizes that this is not restricted.

It is narrow due to being mapped in each channel in addition to NSCH of NB-IoT system in a kind of possible embodiment Band reference signal (narrow band reference signal, NRS), therefore, does not make to make full use of NB-IoT system Carrier resource, the method in the embodiment of the present application can also include:

The network equipment of step 203:NR system determines the resource location of the NRS of NB-IoT system.

In the following, the resource location of the NRS of NB-IoT system is introduced.

In the time-frequency money that the terminal device of the network equipment and NB-IoT system for NB-IoT system carries out data transmission In source, the network equipment of NB-IoT system can be based on NRS pattern, determined and used as unit of the corresponding resource granularity of NRS pattern NRS is sent to the terminal device of NB-IoT system in the RE of transmission NRS, and in the RE.

The second way: the frequency domain position is offset of the NRS mapped subcarrier relative to default frequency domain position.Example Such as, which is the starting subcarrier of NB-IoT system, then the offset be NRS mapped subcarrier relative to The offset of subcarrier is originated, in fig. 8, which is 0.

Since NRS is repeated as unit of subframe in the time domain, the information for being used for transmission the RE of NRS can be only Frequency domain position comprising the NRS in a subframe.

The mode that the network equipment of NR system obtains the information is similar to step 201 and step 202, and details are not described herein.

The first information is used to determine the frequency domain position of N number of subcarrier in 12 subcarriers of NB-IoT system, this One information may be used to determine the frequency domain position of a subcarrier in 12 subcarriers of NB-IoT system, for example, this first Information is used to determine that the frequency domain position of the central subcarrier of NB-IoT system or the first information are used to determine NB-IoT system The 1st subcarrier frequency domain position, etc.；The first information can also be used to determine multiple subcarriers in 12 subcarriers Frequency domain position, for example, the first information is used to determine the 1st subcarrier and the 12nd subcarrier of NB-IoT system respectively Frequency domain position or the first information are used to determine the 1st subcarrier, the 2nd subcarrier and the 11st of NB-IoT system respectively The frequency domain position of a subcarrier or the first information are used to determine in 12 subcarriers of NB-IoT system that every height carries respectively The position of wave, in the embodiment of the present application with no restriction.

It should be noted that the first information can be high-level signaling, for example, wireless heterogeneous networks (radio resource Control, RRC) signaling, system broadcast message, the terminal device multicast message of NR system etc..

The content that the first information specifically includes can be any one in following three kinds of contents, certainly, in the first information The content for including is not limited to following three kinds of situations:

The first: the first information may include the frequency domain position of 1 predetermined sub-carriers of NB-IoT system.1 predetermined The subcarrier of justice can be the subcarrier 0, subcarrier 6 or any one other subcarrier of NB-IoT carrier wave, then working as notice The frequency domain position of the subcarrier, the then it is known that frequency domain position of 12 subcarriers of NB-IoT carrier occupancy.With predefined The subcarrier 0 of NB-IoT system is for needing the information that notifies:

Then a kind of optional mode are as follows: the subcarrier 0 in the first information comprising NB-IoT system is in the corresponding PRB of NR system Number and subcarrier number, the range of PRB number can be 0~to SC_max×N_RB- 1 or 0 arrives (∑ SC_i+1)×N_RB- 1, wherein SC_maxIt is the ratio of maximum subcarrier 60kHz and 15kHz subcarrier spacing that 6GHz or less frequency range is supported, such as SC_maxEqual to 4； N_RBCorrespond to the PRB number of subcarrier spacings maximum support, such as N_RBIt is 275, ∑ SC_iIndicate that 6GHz or less frequency range is supported Each sub-carrier and 15kHz subcarrier spacing ratio sum, such as 60kHz and 15kHz subcarrier spacing ratio, The sum of ratio and the ratio of 15kHz and 15kHz subcarrier spacing of 30kHz and 15kHz subcarrier spacing, i.e. 4+2+1；Son carries Wave number may range from 0~11.Such as the PRB number in the first information including is 30, subcarrier number 0, then it represents that 1st subcarrier of NB-IoT system is located at the 1st corresponding frequency domain position of subcarrier in the PRB30 of NR system.

Another optional mode are as follows: the subcarrier 0 in the first information comprising NB-IoT system is in the corresponding son of NR system The Serial Number Range of carrier index information, sub-carriers can be 0~SC_max×N_RB×N_SC- 1 or 0~(∑ SC_i+1)×N_RB* N_sc- 1, wherein be the ratio of maximum subcarrier 60kHz and 15kHz subcarrier spacing that 6GHz or less frequency range is supported, such as equal to 4；Correspond to a subcarrier spacings maximum support PRB number, for example, 275, indicate 6GHz or less frequency range support it is various The sum of the ratio of subcarrier and 15kHz subcarrier spacing, for example, the ratio of 60kHz and 15kHz subcarrier spacing, 30kHz and The sum of ratio and the ratio of 15kHz and 15kHz subcarrier spacing of 15kHz subcarrier spacing, i.e. 4+2+1.N_SCRefer to one The sub-carrier number for including in PRB, such as N_SCIt is 12.In this way, being indicated when the subcarrier number for including in the frequency domain information is 359 First subcarrier of NB-IoT carrier wave is located at first subcarrier in the PRB30 of NR system.

Second: the first information may include the offset information of PRB number and sub-wave length, wherein the model of PRB number Enclose can be 0~to SC_max×N_RB- 1 or 0 arrives (∑ SC_i+1)×N_RB- 1, wherein SC_maxIt is the maximum that 6GHz or less frequency range is supported The ratio of subcarrier 60kHz and 15kHz subcarrier spacing, such as SC_maxEqual to 4；N_RBCorrespond to subcarrier spacings maximum The PRB number of support, such as N_RBIt is 275, ∑ SC_iBetween each sub-carrier and 15kHz subcarrier that indicate the support of 6GHz or less frequency range Every ratio sum, such as the ratio of the ratio of 60kHz and 15kHz subcarrier spacing, 30kHz and 15kHz subcarrier spacing with And the sum of ratio of 15kHz and 15kHz subcarrier spacing, i.e. 4+2+1；The deviation range of sub-wave length is 0~11, for example, logical The PRB number known is PRB0, and sub-carrier offset magnitude is 4.

The third: the first information may include the absolute frequency point number of NB-IoT carrier wave and the carrier center phase of NB-IoT carrier wave For the offset information of absolute frequency point number, the method for determination of the absolute frequency point number and offset content corresponding with step 201 Identical, details are not described herein.

In this way, the network equipment of NR system indicates the frequency domain of the subcarrier of NB-IoT system to the terminal device of NR system Position, can be to avoid the network equipment of NR system using being unable to fully utilize NB-IoT system caused by PRB grade of indicating mode The problem of not used carrier resource.

Specifically, when NB-IoT system is deployed on NR carrier wave using IB GB deployment way, in order to reduce NB- Interference of the carrier wave of IoT system to the carrier wave of NR system, in a communications system, it is desirable that the subcarrier and NR system of NB-IoT system Subcarrier alignment, as shown in Figure 10.And by the introduction of the aforementioned subcarrier to NR system and the subcarrier of NB-IoT system It is found that the center of NR carrier wave is located on the raster of 100kHz, i.e. the center position offsets of any two NR carrier wave are The integral multiple of 100kHz, similar, the center of the carrier wave of NB-IoT system also is located on the raster of 100kHz.So, When NB-IoT system uses IB deployment way, in order to guarantee the subcarrier of NR system and the subcarrier alignment of NB-IoT system, Then the offset of the center of the carrier wave of the carrier center position and NR system of NB-IoT system is at least 100kHz and 15kHz Least common multiple, i.e. 300kHz, similarly, since a PRB includes 12 subcarriers on frequency domain, then in order to guarantee NB- The PRB pair of the PRB and NR system of IoT system is neat, then in the carrier wave of the center of the carrier wave of NB-IoT system and NR system The offset of heart position is at least the least common multiple of 100kHz and 15*12 (i.e. 180kHz), i.e. 900kHz.In this way, in NB- Under the premise of the subcarrier of IoT system and the subcarrier alignment of NR system, the PRB of PRB and the NR system of NB-IoT system can go out Now it is more than (900-300)/900, i.e., 2/3 probability is misaligned, and as shown in figure 11, a PRB of NB-IoT system is on frequency domain Cover the PRB of two NR systems.In this case, if the network equipment of NR system uses PRB grades of indicating mode to NR When frequency domain resource shared by the terminal device instruction NB-IoT system of system, in order to avoid NR system uses the frequency of NB-IoT system Domain resource, the network equipment of NR system need for PRB0, PRB1, PRB5 and PRB6 shown in Figure 11 to be all indicated to the end of NR system End equipment, but actually NB-IoT system has only used the right half part resource of PRB0 and PRB5 and a left side half of PRB1 and PRB6 Part resource, but NR system is not available the left-half resource of PRB0 and PRB5 and the right half part money of PRB1 and PRB6 yet Source, thus the problem of causing NR system to be unable to fully carrier resource not used using NB-IoT system.

And the subcarrier of NR system and the subcarrier of NB-IoT system are alignment, when the network equipment of NR system is to NR system When the terminal device of system indicates the frequency domain position of the subcarrier of NB-IoT system, the terminal device of NR system can accurately really Determine the position for multiple subcarriers that NB-IoT system occupies on frequency domain, and then by way of reducing and indicating granularity, makes NR system System can make full use of the not used carrier resource of NB-IoT system.

2) first information includes the time-domain information for determining NB-IoT system mapped channel.

In the embodiment of the present application, the content for including according to the time-domain information is different, the content of first information instruction Difference can specifically be divided into following three kinds:

The first: the time-domain information of sub-frame level.

The time-domain information of sub-frame level is for determining the subframe that NPSS signal, NSSS signal and NPBCH occupy in the time domain Information.

Specifically, the content that the first information includes may include but be not limited to the following two kinds situation:

The first situation: the network equipment of NR system carries NPSS signal, NSSS signal and NPBCH in the first information The subframe occupied in the time domain of NR system.

For example, may include a bit map (bitmap) in the first information, which is used to indicate at one section Between, the case where such as 5ms, 10ms, 20ms, 40ms, the channel of the NB-IoT system mapped in each subframe of NR system.It should A bit in a bitmap corresponding chronomere may include integer OFDM symbol in the chronomere, time slot, micro- Time slot, subframe, frame or Transmission Time Interval etc. are specifically a subframe, bitmap instruction 10ms with the chronomere The subframe occupancy situation of interior NR system, for example, the bitmap be " 1000010001 ", when bit value be 1, indicate the bit pair Any one in the subframe mapping NPSS signal of NB-IoT system, NSSS signal and the NPBCH answered, when the value of bit is 0, Indicate that the corresponding subframe of the bit does not map the channel of NB-IoT system.

Second situation: the network equipment of NR system carries No. SFN of NB-IoT carrier wave relative to NR in the first information Offset information of the subframe numbers of carrier wave SFN offset and NB-IoT carrier wave relative to NR carrier wave subframe numbers.

For example, the network equipment of NR system determines the SFN0 of the corresponding NB-IoT system of the SFN1 of NR system, subframe 0, subframe 0, and NPSS signal, NSSS signal and NPBCH NB-IoT system a SF map subframe be subframe 0, subframe 9 and Subframe 5, so that it is determined that NB-IoT carrier wave SFN is 1023 relative to NR carrier wave SFN offset, it can be considered (NB- The difference+1024 of the SFN of SFN and the NR system of IoT system) mod 1024 (can also be with mould 2, because of NSSS every two system-frame Just there is a NSSS) obtained value, NB-IoT carrier wave subframe numbers are 0 relative to the offset of NR subframe numbers.NR by the two Offset information is notified to the terminal device of NR system, so that the terminal device of NR system can determine No. SFN according to the information NPSS, the mapping NPBCH of subframe 5 are mapped for the subframe 0 in the SF of even number, subframe 1~4,6~9 can map NPDSCH/ NPDCCH；No. SFN maps NPSS/NSSS/NPBCH for the subframe 0/5/9 in the SF of odd number respectively, owns what NR system included Remaining subframe can map NPDSCH/NPDCCH in SF.

In this way, the network equipment of NR system notifies that the terminal to NR system is set by the information of NB-IoT carrier wave sub-frame level It is standby, so that the terminal device of NR system, which can determine, the mapping of NPSS/NSSS/NPBCH channel in the corresponding subframe of NR, due to NPSS signal, NSSS signal and NPBCH are mapped since the 4th OFDM symbol in each subframe, and therefore, NR system can be with Utilize the preceding 3 OFDM symbols mapping mapping NR of NPSS signal, NSSS signal and NPBCH in the corresponding subframe of NR carrier wave Signal/channel.

Second: the time-domain information of symbol level.

The time-domain information of symbol level may include the information of the starting OFDM symbol of NPDCCH and NPDSCH mapping, then this One information is also used to indicate the information of the starting OFDM symbol of NPDCCH and NPDSCH mapping.

Specifically, it can indicate what NPDCCH and NPDSCH mapped in subframe with two bits in the first information Originate the information of OFDM symbol, the value of the bit can be 0-3, for example, indicated when the value of the bit is 0 NPDCCH and The starting OFDM symbol that NPDSCH maps in subframe is the 1st OFDM symbol.

In this way, the network equipment of NR system is by being indicated to NR system for the starting OFDM symbol of NPDCCH and NPDSCH mapping The terminal device of system, since the NPDCCH and NPDSCH starting OFDM symbol mapped occupies subframe 1-4 and son on each SF One or more of frame 6-8, therefore, subframe 1-4 and subframe 6-8, NR system on each SF can use NPDCCH Resource corresponding with the symbol before the starting OFDM symbol of NPDSCH mapping.

The third: time-domain information includes the time-domain information of sub-frame level and the time-domain information of symbol level, i.e., the third is aforementioned Two kinds of combination, the then content that the first information includes can be aforementioned two kinds of set, and details are not described herein.

3) first information is also used to indicate the information of the RE for being used for transmission NRS of NB-IoT carrier wave.

In the embodiment of the present application, be used for transmission the RE of NRS information include NB-IoT system antenna port number and The frequency domain position of NRS.Wherein, which can have the following two kinds indicating mode:

First way: the frequency domain position can be the subcarrier of the NRS mapped NB-IoT system in a slot Position.For example, in fig. 8, NRS is mapped in the 1st subcarrier, the 4th subcarrier, the 7th subcarrier of NB-IoT system And on the 10th subcarrier.

The second way: the frequency domain position is that NRS mapped originates offset of the subcarrier relative to default frequency domain position Amount.For example, the default frequency domain position is the starting subcarrier of NB-IoT system, then the offset is NRS mapped starting Offset of the carrier wave relative to starting subcarrier, in fig. 8, the offset are 0.

It certainly, can also simultaneously include above-mentioned three kinds of contents in the first information, i.e., comprising for determining NB-IoT carrier wave 12 Frequency domain position, the NPSS signal, NSSS of the frequency domain position of a sub- carrier occupancy, 1 subcarrier in 12 subcarriers of system The information of the starting OFDM symbol of information and NPDCCH and the NPDSCH mapping for the subframe that signal and NPBCH are occupied in the time domain When, the network equipment of NR system also can be used to be indicated with the specific information of the terminal device of NR system agreement.This is specific Information may include the predefined subcarrier in 12 subcarriers for calculating NB-IoT system relative to NR system Offset, the 5th subcarrier, the 6th subcarrier, the 10th subcarrier or the 11st of the predefined subcarrier NB-IoT system A subcarrier etc. can also include the information for being used to indicate the starting OFDM symbol of NPDCCH and NPDSCH mapping, the starting The information of OFDM symbol can indicate any one value in 0-3, can also comprising be used to indicate NPSS signal, NSSS signal with And the information of offset of the subframe that occupies in the time domain of NPBCH in a SF, the value of the offset can be to appoint in 0-9 It anticipates one kind, for example, the value is 0 when offset of the subframe that occupies of characterization NPSS signal in a SF.

When NR system and LTE system and NB-IoT system share carrier resource, if LTE system needs to share using this Carrier resource transmit CRS, then the network equipment of NR system also need to the terminal device of NR system indicate LTE system CRS The resource of the RE occupied in each subframe.For example, bandwidth of the network equipment of NR system by the carrier wave of notice LTE system, The position of the central subcarrier of LTE system, the antenna port number of the CRS of LTE system and the CRS of LTE system are on frequency domain Offset.In this case, the first information can carry the network equipment in NR system and indicate to the terminal device of NR system In the information of the CRS of LTE system.For example, the network equipment in NR system indicates LTE system to the terminal device of NR system In the information of CRS, increases the bandwidth that bandwidth is 1 PRB, be denoted as N1, when the value of the bandwidth of the LTE system of instruction is N1, Then indicate the configuration information in the information both for NB-IoT system.In this case, in the network equipment of NR system It needs to increase into the information of the CRS of the terminal device of NR system instruction LTE system and is used to indicate NPDCCH and NPDSCH mapping Starting OFDM symbol information, and be used to indicate NPSS signal, the subframe that NSSS signal and NPBCH are occupied in the time domain The information of offset in a SF, being specifically defined for the two information is identical with aforementioned dedicated order, herein no longer It repeats.

It should be noted that two kinds of concrete forms of the above-mentioned first information are only a kind of exemplary illustration, rather than to first The limitation that the concrete form of information carries out, those skilled in the art can also use other forms.

The terminal device of step 205:NR system determines the frequency domain resource and NB-IoT of NB-IoT system according to the first information System is in the running time-frequency resource occupy when channel mapping.

When the content difference of first information instruction, the terminal device of NR system can determine respectively according to the first information The time-domain resource and/or frequency domain resource of NB-IoT system are specific to determine that method is abovementioned steps 201, step 202 and step 203 inverse process, details are not described herein.After terminal device determines the time-domain resource and/or frequency domain resource of NB-IoT system, then Determine that the resource in NR system in addition to the time-domain resource of NB-IoT system and/or frequency domain resource is that the network equipment of NR system is The resource of terminal equipment configuration.For example, the first information includes the corresponding frequency domain resource of 12 subcarriers of NB-IoT system, then eventually End equipment determines the resource in the carrier resource of NR system in addition to the corresponding frequency domain resource of 12 subcarriers of NB-IoT system, is The resource that the network equipment of NR system configures for it.When the first information includes other content, the determination NR system of terminal device The network equipment for its configuration resource method as hereinbefore, details are not described herein.

If the first information includes the information of the RE for being used for transmission NRS of NB-IoT system, the method in the embodiment of the present application Further include:

The network equipment of step 206:NR system sends the second information to the terminal device of NR system, and the terminal of NR system is set It is standby to receive second information.

In the embodiment of the present application, it is determined as unit of which is used to indicate in a chronomere by subcarrier NB-IoT system mapped frequency domain resource, or, determining NB-IoT system as unit of being used to indicate in a chronomere by RE System mapped frequency domain resource.Wherein, a chronomere can be subframe or time slot or mini-slot etc., and this is not restricted. It is illustrated so that a chronomere is a subframe as an example in the following description.

When NB-IoT system has any channel of mapping in the carrier wave of NB-IoT system, i.e., NB-IoT system is in NB-IoT system When mapping any one or more channel in NPBCH, NSCH, NPDCCH and NPDSCH in the carrier wave of system, the second information exists Value in the corresponding subframe of the channel can indicate that NB-IoT system has map channel in the subframe, and then indicate NR system with 1 The terminal device of system is in the subframe by the frequency domain resource of NB-IoT system determining as unit of subcarrier.For example, the net of NR system Network equipment determines that starting OFDM symbol of each channel in the subframe mapped to is the 4th OFDM symbol, then when the second letter Breath the value in the corresponding subframe of the channel be 1 when, then the network equipment of NR system then determine each subcarrier from the 4th 11 OFDM symbols that OFDM symbol starts are the resource that NB-IoT system is mapped in the subframe.When NB-IoT system is in NB-IoT When in the carrier wave of system without mapping any channel, due to being still to transmission NRS in subframe, the second information is in the corresponding son of the channel Value on frame can indicate that NB-IoT system does not have map channel in the subframe, and then indicate the terminal device of NR system with 0 By the frequency domain resource of NB-IoT system determining as unit of RE in the subframe.For example, the network equipment of NR system is determined for passing The resource of the RE of defeated NRS is resource corresponding with NRS pattern shown in Fig. 8, then when the second information is in the corresponding subframe of the channel On value when being 0, then the network equipment of NR system then determines in each slot of the subframe, the on first subcarrier The corresponding RE resource of the 7th OFDM symbol in the corresponding RE resource of 6 OFDM symbols, the 4th subcarrier, the 7th subcarrier On the corresponding RE resource of the 6th OFDM symbol and the corresponding RE resource of the 7th OFDM symbol on the 10th subcarrier be The resource that NB-IoT system is mapped in the subframe.

Specifically, the second information can be corresponding with each subframe of NR system, i.e., one subframe corresponding one has second Information；Second information can also be corresponding with several subframes of NR system, i.e. includes the use of multiple subframes in second information In the information which kind of unit to determine NB-IoT system mapped frequency domain resource using determined, for example, including one in the second information Each subframe of a SF determines the information of NB-IoT system mapped frequency domain resource, the letter of each subframe using which kind of unit Cease a corresponding bit.For example, the terminal device of NR system determines the corresponding NB- of the SFN1 of NR system, subframe 0 by step 204 The SFN0 of IoT system, subframe 0, then NB-IoT system map channel since the 2nd SF of NR system, and in each SF 1st subframe is used to map NSSS signal for mapping NPSS signal, the 5th subframe for mapping NPBCH, the 9th subframe, with And NPDCCH and NPDSCH is mapped since the 3rd OFDM symbol of each subframe, when the information that the second information includes is " SFN1:1001010011 ", then it represents that in the 1st subframe, the 4th subframe, the 6th subframe, the 9th of the 2nd SF of NR system There is map channel in a subframe and the 10th subframe, so that subcarrier be used to determine NB-IoT system for unit in these subframes Mapped frequency domain resource, and the terminal device of NR system is determined to show to penetrate in the 1st subframe by aforementioned process and is NPSS signal, NPSS signal are mapped since the 4th OFDM symbol of subframe, and therefore, the terminal device of NR system determines The carrier wave of entire NB-IoT system can be used in the 1st subframe preceding 3 symbols in the time domain of the 2nd SF of NR system Frequency domain resource.The terminal device of NR system determine by aforementioned process the 2nd subframe be for mapping NPDCCH, by The value of the corresponding bit of 2 subframes of Yu Yu is 0, therefore, NPDCCH is not mapped in the subframe, at this time the terminal of NR system Equipment then determines the RE resource that can be used other than the RE of mapping NRS in the 2nd subframe, the method for determination of other subframes Identical as the 1st subframe and the 2nd subframe, details are not described herein.

In this way, the network equipment of NR system can indicate a subframe to the terminal device of NR system by the second information Or the running time-frequency resource occupied on time slot or mini-slot by NB-IoT system.

It should be noted that due to high-level signaling, for example, the terminal device of RRC signaling, system broadcast message, NR system Multicast message etc. cannot achieve real-time notice, and therefore, the second information can be Downlink Control Information DCI, then the second information can NB-IoT system and the shared carrier resource of NR system dynamic may be implemented in some domain in DCI, and then through DCI.

It should be noted that if the network equipment of NR system is not to the use of the terminal device of NR system instruction NB-IoT system In the information of the RE of transmission NRS, thus, the terminal device of NR system can only determine the frequency of NB-IoT system as unit of subcarrier Domain resource, in this case, step 206 is just without carrying out therefore, step 206 does not have to carry out.

The method that the terminal device of NR system determines the running time-frequency resource that NB-IoT system is occupied in each chronomere, with step Identical described in rapid 205, details are not described herein.

It should be noted that step 207 is optional step, that is, it is not required execution.When the network equipment of NR does not execute Step 206, then the terminal device of NR can not also execute step 207.

After the terminal device of NR system determines the time-domain resource and frequency domain resource that NB-IoT system occupies, it is determined that NR system The network equipment of system is that the resource of the terminal equipment configuration of NR system is in the carrier wave of NB-IoT system except NB-IoT system occupies Time-domain resource and frequency domain resource except resource.
