The working group (WI) of miscellaneous degree MTC (LC-MTC) is over, and will be declined according to the complexity (cost) of its result of study MTC UE
Nearly 50%.In the version 13 of LTE, reached an agreement on and established another working group, be dedicated to further decreasing the complexity of MTC/at
This, and the covering of enhancing MTC, and improve the power consumption of MTC UE.It is a kind of reduce complexity technology be by the nothing of LC-MTC UE
Line electric frequency (RF) bandwidth is contracted to 1.4MHz (being operated using 6 Physical Resource Block (PRB)).In nearest 3GPP
In RAN1 meeting (3GPP RAN1#78bis), in all complexity reduction technologies, bandwidth diminution is given highest preferential
Grade.Therefore, herein, will be discussed using this operation in the example of LC-MTC UE as the Bandwidth-Constrained UE of 1.4MHz,
It should be noted, however, that method and apparatus disclosed in this specification is equally applicable to other bandwidth limited devices.
For Bandwidth-Constrained UE, it may be desirable to which it can be operated in the communication system of any bandwidth, and and just
Normal UE coexists within the system.It is also expected to this Bandwidth-Constrained UE can adjust its working frequency, so as in biggish system
It works on any relatively narrow subband in regiment commander's width to allow the multiplexing between Bandwidth-Constrained UE and the multiplexing between normal UE.
In current LTE system, UE needs to feed back positive acknowledgment after receiving the downlink data from base station
(ACK) or negative confirmation (NACK), the feedback physically transmission in Uplink Control Channel (PUCCH).According to current
LTE standard is located at the both ends of system bandwidth for PUCCH resource, as shown in Figure 1.In order to obtain frequency diversity gain, in single

For wide constrained devices, current this frequency hopping operation be can be challenging for.Because being executed between the both ends of system bandwidth
Frequency hopping will lead to UE transmission subband variation, thus need the end UE execute frequency reset, and frequency reset during will be so that just
Normal transmission can not carry out.If base station still carries out receiving the decline that will lead to reception and demodulation performance according to normal transmission.
Another direct solution be frequency hopping is limited in the relatively narrow bandwidth of operation of bandwidth limited devices, as shown in Fig. 2, but
It is as a result, being difficult to obtain any significant diversity gain.Moreover, the program also brings other problems, for example, its
The transfer resource for physical uplink shared channel (PUSCH) is occupied, which is usually only useful in frequency
Continuous PRB block；In addition, when the subband for distributing to two UE is overlapped, as shown in Fig. 2, then by side in a wherein subband
The PRB of edge distributes to PUCCH, and the surplus resources that will lead in another subband are no longer continuous, can reduce available PUSCH and continuously provide
Source.In addition to this, another to solve the problems, such as being how to notify its available resource of bandwidth limited devices and for each

According to another embodiment of the present invention, it in step S402, determines at least two indicated resource areas
The resource being used for transmission include according to from the base station control channel (for example, physical downlink control channel PDCCH or
The physical downlink control channel EPDCCH of person's enhancing) used in the index of resource impliedly determine for the transmission
Resource.For example, showing the schematic diagram of the resource for PUCCH transmission of embodiment according to the present invention in Fig. 4 c.Show at this
In example, it is assumed that received control information indicates two PUCCH resource regions in Fig. 4 c in step S401.Note that this two
A resource area is not necessarily intended to the edge in same band to obtain frequency diversity gain, as long as between this two interregional
Every sufficiently large.As shown, frequency hopping does not occur on the boundary of two time slots when PUCCH is transmitted in a subframe, this
Different from the operation in current LTE.And for the sake of simplicity, PUCCH transmission occupies same PRB in subframe.In the example
In, it is assumed that each PUCCH resource region includes two PRB, for the resource of PUCCH shares 4PRB.It is according to current
Under unified central planning to set, each PUCCH PRB can support the transmission of 12 PUCCH, and wherein 12 PUCCH are by way of CDMA
Multiplexing.Therefore 4 PRB will provide 48 PUCCH resources.It is assumed that the PUCCH resource in two PUCCH resource regions is by together
It continuously indexs as follows:
PUCCH PRB#1={ 1,5,9,13,17,21,25,29,33,37,41,45 }
PUCCH PRB#2={ 2,6,10,14,18,22,26,30,34,38,42,46 }
PUCCH PRB#3={ 3,7,11,15,19,23,27,31,35,39,43,47 }
PUCCH PRB#4={ 4,8,12,16,20,24,28,32,36,40,44,48 }
That is, including the PUCCH that index is { 1,5,9,13,17,21,25,29,33,37,41,45 } in the first PUCCH PRB
Resource.It is assumed that according to given mapping relations, for sending downlink scheduling message to the equipment in downlink
Resource index used in EPDCCH (such as index of first control resource unit CCE used in the EPDCCH) is impliedly
It is directed toward PUCCH index 7 and then according to index above it was determined that the PUCCH is located at the 3rd PRB, belongs to the second PUCCH resource
Region.The equipment can determine the resource for PUCCH transmission as a result,.
According to another embodiment of the present invention, the resource that can be used for EPDCCH includes more than one subband, and in step
In S402, determine that the resource being used for transmission at least two indicated resource areas includes that determination is configured for EPDCCH
Subband, according to for EPDCCH subband (that is, transmission EPDCCH used in subband) and at least two PUCCH resource
Mapping relations between region determine the resource area in at least two PUCCH resources region for PUCCH transmission；And into
The index of one step resource according to used in the EPDCCH from the base station is impliedly determined in identified resource area
In for the PUCCH transmission resource.For example, still assuming that received control information indicates in Fig. 4 c in step S401
Two PUCCH resource regions.In this example, as an example embodiment that for two EPDCCH subbands of the device definition, i.e.,
EPDCCH subband 1 and EPDCCH subband 2.According to one embodiment of present invention, base station can be used in each odd numbered sub-frames
EPDCCH subband 1, and transmitted in even subframe using EPDCCH subband 2 to obtain classification gain.In this example, false
PUCCH resource in fixed two PUCCH resource regions is indexed as follows respectively:
PUCCH resource region 1:
PUCCH PRB#1={ 1,3,5,7,9,11,13,15,17,19,21,23 }
PUCCH PRB#2={ 2,4,6,8,10,12,14,16,18,20,22,24 }
PUCCH resource region 2:
PUCCH PRB#3={ 1,3,5,7,9,11,13,15,17,19,21,23 }
PUCCH PRB#4={ 2,4,6,8,10,12,14,16,18,20,22,24 }
According to one embodiment of present invention, the PUCCH resource region for being used for PUCCH transmission is depended under the transmission of base station
The subband of the used EPDCCH of downlink schedule information.In this example it is assumed that in the subband for EPDCCH (that is, transmission
Subband used in EPDCCH) and two PUCCH resource regions between there are 1 pair 1 of mapping relations, for example, if using
EPDCCH subband 1, then corresponding PUCCH will use PUCCH resource region 1 to transmit；And if having used EPDCCH
Band 2, then corresponding PUCCH will use PUCCH resource region 2 to transmit.It is assumed that base station is had sent using EPDCCH subband 1
PDSCH scheduling grant, and the EPDCCH resource implicitly points to PUCCH index 9, then and the equipment is it was determined that be used for PUCCH
The resource of transmission is the PUCCH resource 9 in PUCCH resource region 1.
According to another embodiment of the present invention, which is configured for multiple control channel set, such as multiple EPDCCH
Set, and descending scheduling license will be detected in the search space of multiple EPDCCH.In this embodiment, in step S402
In, determine that the resource being used for transmission at least two indicated resource areas includes, based on the carrying from the base station
Such as control channel set used in the control channel (such as EPDCCH) of scheduling information (such as EPDCCH set) determines
The resource area of the transmission is used in indicated at least two resource area.In one embodiment, exist
There are the mapping relations similar with a upper embodiment between EPDDCH set and multiple PUCCH resource regions, thus the equipment energy
It is enough that the resource being used for transmission at least two resource areas is determined according to similar method.
If uplink control information entrained by PUCCH (UCI) completes transmission, diversity gain in a single sub-frame
Effect be embodied in, the transmission for multiple UCI message can obtain preferable average behavior.Because certain UCI are in a subband
It is middle transmission and other UCI are transmitted in other subbands, if multiple UCI it is related to single downstream data packet (for example, each
UCI message includes the different HARQ feedbacks retransmitted for same data grouping), then as a whole can for the feedback of the grouping
Enough obtain diversity gain.In another example, if UCI message includes channel state information (CSI) feedback, by CSI feedback
As a whole, diversity gain can be obtained.
According to one embodiment of present invention, the transmission of step S403 is completed in more than one (such as N > 1) subframe,
And wherein determine that the resource being used for transmission at least two resource areas indicated by the control information in step S401 includes:
The resource for the transmission is determined based on the number (such as value of N) of the more than one subframe.As an example, the biography
The defeated PUCCH transmission that can be Bearer Channel status information (CSI).It is assumed that the CSI information is transmitted in the subframe of N > 1.
Then as an example, the PUCCH resource that can be used in i-th of PUCCH resource region in the preceding N/2 subframe is transmitted, and
The resource that j-th of resource area at least two resource area can be used in rear N/2 subframe is transmitted, wherein
J is different from i.According to an embodiment of the invention, different the resource area i and j, which are located in system bandwidth, has certain frequency
The different sub-band at interval, so that diversity gain can be obtained in the transmission of the CSI information by this transmission mode.
According to one embodiment of present invention, the transmission of step S403 is completed in more than one (such as N > 1) subframe,
And it is executed in multiple subframe and repeats to transmit, in this case, embodiment according to the present invention can be based on number of repetition
To determine the resource for the transmission.An example is provided referring to Fig. 4 c-4d.It is assumed that received control information refers in S401
As illustrated in fig. 4 c, and the PUCCH resource in each PUCCH resource region is indexed as follows in the PUCCH resource region shown:
PUCCH resource region 1:
PUCCH PRB#1={ 1,3,5,7,9,11,13,15,17,19,21,23 }
PUCCH PRB#2={ 2,4,6,8,10,12,14,16,18,20,22,24 }
PUCCH resource region 2:
PUCCH PRB#3={ 1,3,5,7,9,11,13,15,17,19,21,23 }
PUCCH PRB#4={ 2,4,6,8,10,12,14,16,18,20,22,24 }
In this example it is assumed that the equipment of the Bandwidth-Constrained be need the MTC device (CE-MTC) of coverage enhancement, and its
PUCCH needs to repeat transmission N=8 times.According to an embodiment of the invention, can be by 8 transmission divided by the PUCCH resource being instructed to
The number (resource area number is 2 in this example) in region, obtains time of the repetition executed in each resource area transmission
Number.Thus, it is possible to obtain executing 8/2=4 repetition in each resource area.It is assumed that used EPDCCH is impliedly indicated
PUCCH resource 9 in PUCCH resource region 1 can then pass through the PUCCH resource in the PRB#1 in PUCCH resource region 1
9 execute the 1 to 4th repetition, and the PUCCH resource 9 in the PRB#3 in PUCCH resource region 2 executes the 5-8 times repetition to obtain
Obtain diversity gain.Repetition transmission is schematically shown in figure 4d.It can be seen that in an embodiment of the present invention, being used for
The resource of PUCCH transmission can be the function of number of repetition.
According to an embodiment of the invention, the transmission of step S403 is completed in more than one, such as N > 1 subframe, and should
Method 400 further comprises step S411, for sequentially in time by the N sub-frame division at least two sub-frame sets,
And the different resource region at least two resource area is used in different sub-frame sets in step S403 step
Resource transmitted, as shown in Figure 4 b.According to one embodiment of present invention, the division can according to it is scheduled rule into
Row, or operated according to the configuration signal from base station.For example, N=16 subframe can be divided into 4 in chronological order
Set, so that the 1st set includes subframe 1-4, the 2nd, 3,4 set respectively include subframe 5-8,9-12,13-16.In different subframes
Subframe in set does not overlap in time, thus within the duration of a sub-frame set in same resource area into
Row transmission without carry out frequency readjustment, this avoids frequent frequency reset operation reduce thus bring switching when
Prolong.Since the change in the region PUCCH will need frequency to reset, and frequency readjustment will interrupt the normal transmission of PUCCH, therefore,
The requirement that the embodiment resets minimum to frequency, this is advantageous the transmission of bandwidth limited devices.According to the present invention
Embodiment, method 400 further comprises step S412, and frequency error factor is executed between different sub-frame sets for determining
Transmission gap；And the transmission is not executed during the identified transmission gap in step S403.The transmission gap
For making equipment carry out frequency readjustment.Realized according to current device, the time which needs will less than 1 subframe lengths,
