101 :User equipment determines N number of running time-frequency resource for transmitting N number of targeting sequencing, One running time-frequency resource of each targeting sequencing correspondence, it is different that the running time-frequency resource includes at least two in time resource and frequency resource, the frequency resource of N number of running time-frequency resource；

Wherein, user equipment determines that N number of running time-frequency resource for transmitting N number of targeting sequencing specifically can be comprising two aspects：

(1) user equipment determines the format information of N number of targeting sequencing, wherein, the format information includes N value, and/or the sequence that each targeting sequencing is included.The optional format information can be the leading form of existing system, and now N value can be determined according to the descending measurement of user equipment or is determined according to the signaling received.

Wherein, the sequence can be the sequence randomly generated, or predefined sequence, or the sequence produced according to existing system method, because the realization on the object of the invention does not constitute influence, the embodiment of the present invention is not limited to this.In addition, N targeting sequencing can include identical sequence, different sequences can also be included, equally the realization not on the object of the invention does not constitute influence, therefore the embodiment of the present invention is not limited to this.Wherein, the leading form of existing system is leading form 0, leading form 1, leading form 2, leading form 3, leading format 4.

(2) user equipment determines the information of the running time-frequency resource of each targeting sequencing in N targeting sequencing.

Wherein, the information and the information of frequency domain resource of time-domain resource of the packet containing the targeting sequencing of the running time-frequency resource of each targeting sequencing, wherein, the time-domain resource includes the very first time resource for being used for transmitting targeting sequencing, and the very first time resource for being used to transmit targeting sequencing is at least one leading symbol.For example, a targeting sequencing includes L leading symbol, the duration of each leading symbol is designated as Tp, then the very first time resource of the targeting sequencing is L*Tp, wherein, L is the integer more than or equal to 1.

Wherein, the duration of each leading symbol is equal to the duration of data symbol；Or, the duration of each leading symbol is less than the duration of data symbol, and is equal to the integer of the data symbol divides one；The data symbol is for transmitting data.It is preferred that, the duration of each leading symbol is less than the duration of data symbol, and one of the integer point equal to the data symbol, so that same time-domain resource can be used for transmitting more leading symbols, the length of targeting sequencing is longer, is conducive to lifting base station to detect performance to targeting sequencing.

It is preferred that, in order to prevent because bad timing causes intersymbol interference, in N number of time-frequency In each running time-frequency resource of resource; the time resource is included outside the very first time resource for transmitting targeting sequencing; also include the second time resource for being used as the rear protection interval of transmission targeting sequencing, the very first time resource with second time resource is front and rear in time is connected.

It is preferred that; in order to avoid being climbed and/or bad timing causes the performance of targeting sequencing to be affected due to power; in each running time-frequency resource of N number of running time-frequency resource; the time resource includes the very first time resource for being used to transmit targeting sequencing; and outside the second time resource of the rear protection interval as transmission targeting sequencing; also include the 3rd time resource for being used as the preceding guard time of transmission targeting sequencing, the 3rd time resource, very first time resource with second time resource is front and rear in time is connected.

It is preferred that, in order to strengthen covering, in each running time-frequency resource of N number of running time-frequency resource, the frequency resource is the arrowband frequency that base station is configured, the arrowband frequency is the part in the carrier frequency that the base station is configured, and the band width of the arrowband frequency is less than the band width of the carrier frequency.

Lower mask body is illustrated.

For example, in the prior art, the frequency domain bandwidth that one targeting sequencing takes is more than or equal to the minimum frequency domain bandwidth that data channel takes, for example, in LTE system, targeting sequencing takes 6 Physical Resource Block 1.08MHz, and data channel minimum takes a Physical Resource Block 180KHz;In gsm system, the Stochastic accessing for Stochastic accessing happens suddenly（Burst identical channel width) is taken with data channel, is 200KHz.

And in embodiments of the present invention, if this 200KHz is equally divided into 2000 parts, there is 2000 100Hz narrow band frequency, i.e. Frequency point in 200KHz.

Relative to prior art, using narrow band transmission（Carrier frequency point of the correspondence with a width of 100Hz）, because bandwidth reduces, keep transmission power constant, the noise power reduction in arrowband, so that signal to noise ratio is improved, enhancing covering.

It should be noted that for LTE system, the band width of carrier frequency can be described as transmission bandwidth or system bandwidth, bandwidth unit available resource block（Resource Block, RB) represent, for example, can be 15 or 25 or 50 or 100RB, it is such as 6RB that now the band width of arrowband frequency, which can be less than carrier frequency broadband, or when carrier frequency bandwidth is 6RB, now the band width of arrowband frequency is as being 3RB. Specifically, user equipment determines that N number of running time-frequency resource for transmitting N number of targeting sequencing can be realized by any one in following four mode.

First way

In this fashion, user equipment determines the information of the running time-frequency resource of each targeting sequencing in the format information and N number of targeting sequencing of N number of targeting sequencing by predefined mode.For example, system predefines the information that the storage system that prestored respectively in the information of the running time-frequency resource of each targeting sequencing in the format information and N number of targeting sequencing of N number of targeting sequencing, user equipment and base station predefines the running time-frequency resource of each targeting sequencing in the format information and N number of targeting sequencing of N number of targeting sequencing.

The second way

In this fashion, user equipment determines that the information of the running time-frequency resource of each targeting sequencing in the format information of N number of targeting sequencing, N targeting sequencing is configured by base station by predefined mode.

Specifically, can be realized by following processes：

User equipment receives the first configuration information that base station is sent, and first configuration information includes the information for being used for indicating N number of running time-frequency resource；

User equipment is according to the format information of the first configuration information, and predefined N number of targeting sequencing, it is determined that N number of running time-frequency resource for transmitting N number of targeting sequencing.Wherein, the information for N number of running time-frequency resource that the first configuration information is indicated can be comprising base station to a Frequency point in N targeting sequencing configuration carrier frequency.Exemplary, base station can configure M carrier frequency Absolute Radio Frequency Channel numbering (Absolute Radio Frequency Channel Number, abbreviation ARFCN) for N number of targeting sequencing and be used as carrier frequency set.For example, the carrier frequency that ARFCN values are in the scopes of 128 n 251 is combined into the carrier frequency collection that frequency band GSM 850 is included, wherein, frequency band GSM 850 is 850 megahertzs of GSM frequency languages（Mega Hertz, abbreviation MHz) frequency range.The corresponding carrier frequency of each ARFCN values is the carrier frequency that corresponding UL is used when corresponding DL is used when ARFCN values are n carrier frequency is n with corresponding ARFCN values, wherein, the carrier frequency that corresponding DL is used when ARFCN values are n can be represented with Fl (n), the carrier frequency that corresponding UL is used when ARFCN values are n can be represented with Fu (n), it can be represented when ARFCN values are n with the relation between Fl (n), Fu (n) with following table, as shown in table 1： Table 1

Upper table it is various in, various output unit is that each n values are the corresponding a width of 200KHz of carrier frequency channel band of ARFCN values in the range of MHz, 128 n 251.When base station is that Frequency point is respectively configured in N number of targeting sequencing, N carrier frequency is selected in the set that base station is constituted elder generation from M carrier frequency, then carry out configuration frequency point.Exemplary, for narrow band transmission, base station is the Frequency point that N number of targeting sequencing is respectively configured in a carrier frequency, specifically with the following two kinds collocation method：

On the one hand, the embodiment of the present invention provides a kind of base station 110, referring to Figure 11, and base station 110 is N number of running time-frequency resource that user device configuration is used to transmit N number of targeting sequencing, and the N is the integer more than or equal to 2, as illustrated, can include： Determining unit 1101, for the N number of running time-frequency resource for determining to be used to transmit N number of targeting sequencing, one running time-frequency resource of each targeting sequencing correspondence, it is different that the running time-frequency resource includes at least two in time-domain resource and frequency domain resource, the frequency resource of N number of running time-frequency resource；

1st, the format information of N number of targeting sequencing, wherein, the format information includes N value, and the sequence that each targeting sequencing is included.

It is preferred that; in order to avoid being climbed and/or bad timing causes the performance of targeting sequencing to be affected due to power; in each running time-frequency resource of N number of running time-frequency resource; the time resource includes the very first time resource for being used to transmit targeting sequencing, and between the rear protection as transmission targeting sequencing Every the second time resource outside, include the 3rd time resource of the preceding guard time as transmission targeting sequencing, the 3rd time resource, very first time resource with second time resource is front and rear in time is connected.

Lower mask body is illustrated.

It should be noted that for LTE system, the band width of carrier frequency can be described as transmission bandwidth or system bandwidth, bandwidth unit available resource block（Resource Block, RB) represent, for example can be 6RB, now the band width of arrowband frequency can be less than 6RB, such as 3RB.Exemplary, for narrow band transmission, determining unit 1101 is the Frequency point that N number of targeting sequencing is respectively configured in a carrier frequency, specifically with the following two kinds collocation method：

1) determining unit 1101 indicates the first frequency point in the corresponding first carrier frequency of the first targeting sequencing for first targeting sequencing of N number of targeting sequencing, and the relation between the corresponding Frequency point of each targeting sequencing and first frequency point in N number of targeting sequencing in addition to the first targeting sequencing is determined respectively, specifically there are following several relations：A) the corresponding frequency of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing Point is identical in the position of first carrier frequency with first frequency point in the position of corresponding carrier frequency；For example, first carrier frequency can be fl, the corresponding carrier frequency of each targeting sequencing in addition to the first targeting sequencing can be f2, f3 ... .., fn, if it is determined that second Frequency point that unit 1101 is fl to the carrier frequency fl of the first targeting sequencing Frequency points configured, then the corresponding Frequency point of each targeting sequencing in addition to the first targeting sequencing is respectively f2, f3, ... .., fn second Frequency point.

B) the corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing has fixed shifted relative value in the position of corresponding carrier frequency relative to first frequency point in the position of first carrier frequency；For example, if it is determined that unit 1101 is the position where fl 100*2 to the carrier frequency fl of the first targeting sequencing Frequency points configured, then the corresponding Frequency point of each targeting sequencing in addition to the first targeting sequencing is respectively f2, f3, ... .., fn's（The position of remainder obtained by 100*2+100)/(200* 10e3).C) the corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing has the shifted relative value related to the logical number of targeting sequencing relative to first frequency point in the position of corresponding carrier frequency in the position of first carrier frequency；

For example, however, it is determined that unit 1101 is the position where fl 100*2 to the carrier frequency fl of the first targeting sequencing Frequency points configured, then the 2nd corresponding Frequency point of targeting sequencing is carrier frequency f²'s（ 100*²+ (2- 1) 100)/(200* 10e3) obtained by remainder position, the 3rd corresponding Frequency point of targeting sequencing is carrier frequency f3's（100*2+ (3- 1) 100)/(200* 10e3) obtained by remainder position, ..., the corresponding Frequency point of n-th targeting sequencing is the position of the remainder obtained by carrier frequency fn (100*2+ (3- 1) 100)/(200* 10e3).D) random site of the corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing in corresponding carrier frequency.For example, second Frequency point that determining unit 1101 is fl to the carrier frequency fl of the first targeting sequencing Frequency points configured, determining unit 1101 is carrier wave to the 136th Frequency point that the 2nd corresponding Frequency point of targeting sequencing is carrier frequency f2, the 3rd corresponding Frequency point of targeting sequencing Frequency f3 the 1985th Frequency point ..., the corresponding Frequency point of n-th of targeting sequencing is carrier frequency fn the 3rd Frequency point.The corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing is unrelated in the position of first carrier frequency in the position of corresponding carrier frequency first frequency point corresponding with the first targeting sequencing.

2) determining unit 1101 indicates respectively a Frequency point in the corresponding carrier frequency of each targeting sequencing for each targeting sequencing of N number of targeting sequencing.Exemplary, determining unit 1101 is that N number of targeting sequencing indicates a period, for example, in LTE system, determining unit 1101 is that N number of targeting sequencing indicates one or more subframes or one or more frames；In gsm system, determining unit 1101 happens suddenly for Stochastic accessing（Burst one or more time slots or burst) are indicated（Burst) time or one or more frames.

Transmitting element 1102, for sending the first configuration information to the user equipment, first configuration information includes the information for being used for indicating N number of running time-frequency resource.

Wherein, user equipment determines that the information of the running time-frequency resource of each targeting sequencing in the format information of N number of targeting sequencing, N number of targeting sequencing is configured by base station by predefined mode.Wherein, the information for N number of running time-frequency resource that the first configuration information is indicated can be comprising base station to a Frequency point in N targeting sequencing configuration carrier frequency.A kind of base station provided in an embodiment of the present invention, it is determined that the N running time-frequency resource for transmitting N number of targeting sequencing, one running time-frequency resource of each targeting sequencing correspondence, it is different that the running time-frequency resource includes at least two in time-domain resource and frequency domain resource, the frequency resource of N number of running time-frequency resource；Base station sends the first configuration information to the user equipment, and first configuration information includes the information for being used for indicating N number of running time-frequency resource.So that user equipment sends N number of targeting sequencing, request Stochastic accessing base station on N number of running time-frequency resource to base station.Frequency range possibility due to multiple frequency resources simultaneously positioned at deep fade is smaller, so as to reduce the probability that base station detects mistake to targeting sequencing, overcome prior art user equipment and carry out Stochastic accessing on a targeting sequencing, and the targeting sequencing uses same frequency resource, when the frequency resource is in the frequency range of deep fade, base station is caused to detect mistake to targeting sequencing.Also, use narrow band transmission（Carrier frequency point of the correspondence with a width of 100Hz）, because bandwidth reduces, keep transmission power constant, the noise power reduction in arrowband, so that signal to noise ratio is improved, enhancing covering；Number is equal to using the leading symbol duration According to the one of the integer point of symbol duration so that same time-domain resource can be used for transmitting more leading symbols, and the length of targeting sequencing is longer, be conducive to lifting base station to detect performance to targeting sequencing；The setting of guard time can be prevented because bad timing causes intersymbol interference afterwards；The setting of preceding guard time can be avoided because power climbs and/or bad timing causes the performance of targeting sequencing to be affected.

On the one hand, the embodiment of the present invention provides a kind of base station 120, referring to Figure 12, and base station 120 is N number of running time-frequency resource that user device configuration is used to transmit N number of targeting sequencing, and the N is the integer more than or equal to 2, as illustrated, can include：

For example, if processor 1201 is the position where fl 100*2 to the carrier frequency fl of the first targeting sequencing Frequency points configured, the 2nd corresponding Frequency point of targeting sequencing is carrier frequency f's 2（100*2+ (2- 1) 100)/(200* 10e3) obtained by remainder position, the 3rd corresponding Frequency point of targeting sequencing is carrier frequency f3's（100*2+ (3- 1) 100)/(200* 10e3) obtained by remainder position, ..., the corresponding Frequency point of n-th targeting sequencing is the position of the remainder obtained by carrier frequency fn (100*2+ (3- 1) 100)/(200* 10e3).D) random site of the corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing in corresponding carrier frequency.For example, second Frequency point that processor 1201 is fl to the carrier frequency fl of the first targeting sequencing Frequency points configured, processor 1201 is carrier frequency f3 to the 136th Frequency point that the 2nd corresponding Frequency point of targeting sequencing is carrier frequency f2, the 3rd corresponding Frequency point of targeting sequencing The 1985th Frequency point ..., the corresponding Frequency point of n-th of targeting sequencing be carrier frequency fn the 3rd Frequency point.The corresponding Frequency point of each targeting sequencing in N number of targeting sequencing in addition to the first targeting sequencing is unrelated in the position of first carrier frequency in the position of corresponding carrier frequency first frequency point corresponding with the first targeting sequencing.
