Embodiment one:
The sending method of a kind of SRS, sends SRS including in the first bandwidth (being equivalent to above-mentioned nominated bandwidth).First bandwidth is by one or more the discontinuous PRB bunch virtual continuous bandwidth formed.PRB bunch is made up of the multiple continuous print PRB in system bandwidth.Multiple discontinuous PRB bunch of PRB numbers comprised can be the same or different.
Fig. 9 is the first bandwidth schematic diagram according to embodiments of the present invention, as it is shown in figure 9, represent two PRB bunch of system bandwidth bend is invented continuous print first bandwidth, UE will send SRS according to a certain pattern cycle in the first bandwidth.
In order to adopting the SRS bandwidth of 4 PRB to send SRS, the first bandwidth and PRB bunch of PRB number comprised should be all the integral multiple of 4.
First bandwidth can be eNB instruction, and as indicated by public message, such as eNB passes through a certain class UE of SIB message informing, such as arrowband UE, its first bandwidth location or its PRB comprised, such as represents with bitmap.Or by the proprietary message instruction of UE, namely eNB is the UE position indicating first bandwidth of UE, it is possible to is signaled by RRC or is notified by physical layer signaling.Alternatively, UE is divided into a lot of groups, and corresponding for UE the first bandwidth in a group is also identical, and the UE in group sends SRS in the first bandwidth of its correspondence；First bandwidth of the UE of different groups is different.Alternatively, there is no overlap between the first bandwidth that group is corresponding.
First bandwidth can also be default, such as all can corresponding first bandwidth for each system bandwidth, again such as at FDD (FrequencyDivisionDuplexing, referred to as FDD): system, a kind of corresponding relation is there is between downlink bandwidth and upstream bandwidth, first bandwidth can be determined according to the downlink working arrowband distributing to arrowband UE, or determines according to one or more nearest up work arrowband.Or the first bandwidth is preset as transmitting physical Uplink Shared Channel (PhysicalUplinkSharedChanne, referred to as PUSCH) and/or physical uplink control channel (PhysicalUplinkControlChannel, referred to as PUCCH) and/or the frequency domain resource of Physical Random Access Channel (PhysicalRandomAccessChannel, referred to as PRACH).When being used for transmitting the PRB that the frequency domain resource of PUSCH and/or PUCCH and/or PRACH the comprises integral multiple not being 4, the first bandwidth be this frequency domain resource through extension or obtain after reducing comprise 4 the frequency domain resource of integral multiple PRB.Extension or the mode reduced can be predefined or notice.So, in the first bandwidth, integral multiple the PRB of 4 is comprised so that UE can be transmitted according to the SRS of 4 PRB in the first bandwidth.This frequency domain resource being used for transmitting PUSCH and/or PUCCH and/or PRACH is default or what eNB indicated.
Alternatively, if PUSCH and PUCCH and PRACH distinguishes corresponding different narrowband resources, then the first bandwidth is default or the frequency domain resource for transmitting PUSCH of eNB instruction.When being used for transmitting the PRB that the frequency domain resource of PUSCH the comprises integral multiple not being 4, the first bandwidth be this frequency domain resource through extension or obtain after reducing comprise 4 the frequency domain resource of integral multiple PRB.If or PUSCH and PUCCH may possibly be mixed in multiple arrowband send, then the first bandwidth be default or eNB instruction for transmitting PUSCH or the frequency domain resource of mixed transport PUSCH and PUCCH.When being used for transmitting the PRB that the frequency domain resource of PUSCH or mixed transport PUSCH and PUCCH the comprises integral multiple not being 4, the first bandwidth be this frequency domain resource through extension or obtain after reducing comprise 4 the frequency domain resource of integral multiple PRB.
Figure 10 is the schematic diagram of the first bandwidth obtained after frequency domain resource extension according to embodiments of the present invention, as shown in Figure 10, giving the example of an extension, the frequency domain resource for arrowband UE work is made up of 5 arrowbands, and these 5 arrowbands are the frequency domain resource sending PUSCH for UE of eNB notice.Each arrowband comprises 6 PRB, two of which arrowband is continuous print, other three arrowbands are continuous print, define two PRB bunch, respectively 12 PRB and 18 PRB, wherein 18 PRB are not the integral multiples of 4 PRB, by also extending by 2 contiguous PRB, form 20 PRB, become the multiple of 4, then these 12 PRB and 20 PRB form virtual the first bandwidth comprising 32 PRB, and UE adopts the SRS bandwidth of 4 PRB to be transmitted in the first bandwidth.
nullFigure 11 is the schematic diagram of the first bandwidth obtained after frequency domain resource according to embodiments of the present invention reduces，As shown in figure 11，Give an example reduced，Frequency range for arrowband UE work is made up of 5 arrowbands，Each arrowband comprises 6 PRB，Two of which arrowband is continuous print，Other three arrowbands are continuous print，Define two parts working frequency range，Respectively 12 PRB and 18 PRB，Wherein 18 PRB are not the integral multiples of 4 PRB，By 2 minimum for PRB bunch of medium frequency of 18 PRB compositions PRB are removed，Remove by Box Section，Form 16 PRB，Become the multiple of 4，Then these 12 PRB and 16 PRB form virtual the first bandwidth comprising 28 PRB，UE adopts the SRS bandwidth of 4 PRB to be transmitted in the first bandwidth.
After working frequency range is invented the first bandwidth by UE, it is possible to the first bandwidth is used as the frequency domain range of transmission of SRS.The original position that eNB is also notified that its frequency domain of UE, the comb taken, transmission cycle and offset, employing the circulation skew of sequence, UE, according to eNB these information notified, carries out the transmission of SRS in the first bandwidth according to existing frequency pattern.Further, eNB notifies the original position of the frequency domain of UE, it is possible to only indicates in the first bandwidth, such as assumes there are 32 PRB in the first bandwidth, hold altogether the SRS bandwidth of 84 PRB, it is possible to adopt 3bit to indicate original position to be the SRS bandwidth of which 4 PRB.
Figure 12 is the SRS bandwidth of UE in the first bandwidth according to embodiments of the present invention is that SRS when 4 sends schematic diagram, as shown in figure 12, give one and send SRS according to a kind of default regular frequency hopping in the subframe sending SRS, traveling through whole first bandwidth, the symbol wherein sending SRS is shown by black part submeter.This preset rule or frequency hopping formula and the first bandwidth relevant.Practical application is not limited to this transmission mode.
ENB receives SRS according to same rule, it is thus achieved that the channel conditions of UE, and scheduling UE sends upward signal.
It addition, eNB can also configure existing SRS for arrowband UE, namely the frequency domain of frequency hopping is the SRS bandwidth of the community of eNB configuration.Preferably, eNB can bigger by the period assignment of this existing SRS, bigger than the hop period in the present invention, so, eNB is possible not only on the working band of UE quickly receive SRS, obtains the channel conditions of UE, and then dispatches this UE transmission PUSCH, the channel conditions of UE on other frequency bands can also be obtained, as the foundation adjusting UE working band in the future.When the SRS in the first bandwidth in existing SRS and the present invention clash occur in same subframe time, it is possible to define a priority, such as preferential send existing SRS or the preferential SRS sent in the first bandwidth.
This first bandwidth can also be change.The UE#1 frequency range as its transmission SRS is distributed in PRB#0～17 by such as eNB, first UE by its virtual be the first bandwidth, then in the first bandwidth, send SRS, after a period of time, eNB can also notify that its frequency range sending SRS of UE there occurs change, becomes PRB#23～29, after UE receives modification information, by its virtual be the first bandwidth, then in the first bandwidth send SRS.
In order to the SRS of existing LTEUE not interfered and avoided the existing LTEUE interference to arrowband UE, eNB is when configuration parameter, and the resource that should be taken by both UE is separately.ENB can give the circulation skew of sequence differently configured for both UE, and in such as 8 kinds of circulation skews, wherein 4 are allocated to existing LTEUE use, and other several arrowband UE that distribute to use；Or give comb differently configured for both UE, distribute the comb that even subcarriers is corresponding such as to existing LTEUE, distribute, to arrowband UE, the comb that odd subcarriers is corresponding；Or give transmission subframe differently configured for both UE, it is ensured that it will not occur in same subframe；Or give the frequency domain sending SRS that both UE are differently configured, existing LTEUE sends the SRS bandwidth that the frequency domain of SRS is community, typically constitute from several PRB of whole system bandwidth center, it is possible to the frequency domain of arrowband UE transmission SRS is arranged in outside the SRS bandwidth of community；Or also can by above-mentioned any two or multiple carry out combining isolate both UE resource taken.So, although two kinds of UE have employed different SRS hoppings, but will not disturb.

Similar with embodiment one, using first bandwidth frequency domain range of transmission as SRS, this first bandwidth sends SRS.The difference is that, adopt the SRS bandwidth of a kind of 6 PRB to send mode, namely UE sends, at SRS, the SRS sent in subframe and takies 6 PRB on frequency domain.This frequency hopping formula is determined by the first bandwidth.The integral multiple that number is 6 of the PRB that this first bandwidth comprises.The UE configuration according to eNB, sends SRS according to default frequency pattern in the first bandwidth.The original position that eNB can notify its frequency domain of UE, the comb taken, transmission cycle and offset, employing the circulation skew of sequence, frequency-hopping mode is predefined or notice.So, bandwidth is sent for RF and only have the UE of 1.4MHz, it is possible on 6 PRB of its work, send out a SRS taking whole work arrowband, improve the transmitting efficiency of SRS.
Figure 13 is the SRS bandwidth of UE in the first bandwidth according to embodiments of the present invention is that SRS when 6 sends schematic diagram, as shown in figure 13, give the UE example sending SRS in the subframe sending SRS according to a kind of default regular frequency hopping, traveling through whole first bandwidth, the symbol wherein sending SRS is shown by black part submeter.Practical application is not limited to this transmission mode.
Similar with embodiment one, when being used for transmitting the PRB that the frequency domain resource of PUSCH and/or PUCCH and/or PRACH the comprises integral multiple not being 6, the first bandwidth be this frequency domain resource through extension or obtain after reducing comprise 6 the frequency domain resource of integral multiple PRB.
Alternatively, when the common multiple that PRB number is 4 and 6 that the first bandwidth comprises, in the first bandwidth, it is transmitted according to the SRS bandwidth of 4 PRB or the SRS bandwidth of 6 PRB, specifically according to which SRS bandwidth sending can be eNB notice, it is also possible to be default.
Alternatively, if the narrowband resource that PUSCH and PUCCH and PRACH is corresponding different respectively, so the first bandwidth is default or the frequency domain resource for transmitting PUSCH of eNB instruction, or this frequency domain resource through extension or obtain after reducing comprise 6 the frequency domain resource of integral multiple PRB.If or PUSCH and PUCCH may possibly be mixed in multiple arrowband and sends, so the first bandwidth be default or eNB instruction for transmitting PUSCH or the frequency domain resource of mixed transport PUSCH and PUCCH, or this frequency domain resource through extension or obtain after reducing comprise 6 the frequency domain resource of integral multiple PRB.
ENB receives SRS according to same rule, it is thus achieved that the channel conditions of UE, and scheduling UE sends upward signal in this first bandwidth or in this one or more working frequency range.
In order to the SRS of existing LTEUE not interfered and avoided the existing LTEUE interference to arrowband UE, eNB is when configuration parameter, and the resource that should be taken by both UE is separately.ENB can give comb differently configured for both UE, distributes the comb that even subcarriers is corresponding such as to existing LTEUE, distributes, to arrowband UE, the comb that odd subcarriers is corresponding；Or give transmission subframe differently configured for both UE, it is ensured that it will not occur in same subframe；Or give the frequency domain sending SRS that both UE are differently configured, existing LTEUE sends the SRS bandwidth that the frequency domain of SRS is community, typically constitute from several PRB of whole system bandwidth center, it is possible to the frequency domain of arrowband UE transmission SRS is arranged in outside the SRS bandwidth of community；Or also can by above-mentioned any two or multiple carry out combining isolate both UE resource taken.So, although two kinds of UE have employed different SRS hoppings, but will not disturb.
In sum, the sending method of a kind of SRS that the present invention proposes, make MTCUE or arrowband UE efficiently send SRS, eNB and quickly obtain the up channel situation of MTCUE or arrowband UE, it is thus achieved that scheduling gains.
