Below the method for the embodiment of the present invention is further detailed.
System bandwidth can be divided into several arrowbands, and (20MHz is included 100 PRB such as
(Physical Resource Block, Physical Resource Block)) system bandwidth be divided into 16 arrowbands, often
Individual arrowband includes 6 PRB, and remaining 4 PRB are evenly distributed on the both sides of system bandwidth, and 2
Individual PRB.For the definition mode of arrowband in system bandwidth, the present invention is not limited.UE one wherein
Send or receive information on arrowband.The arrowband dividing mode of downlink system bandwidth and up-link bandwidth and
Arrowband numbering is identical, is started from 0 open numbering from low-limit frequency.In such system
In, the Downlink Control Information for dispatching UE is sent on an arrowband, the Downlink Control Information scheduling
Send on PDSCH or PUSCH some PRB also on an arrowband.
For PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel)/PDSCH
(Physical Downlink Shared Channel, Physical Downlink Shared Channel), in order to reduce DCI
The expense of (Downlink Control Information, Downlink Control Information), can be according to default side
Formula determines the arrowband of PUSCH/PDSCH.
ENB (evolved Node B, the node B of evolution) dispatches UE (User Equipment, user
Terminal) arrowband that sends PUSCH/PDSCH selected from a set, and the collection is combined into described
The available arrowband set of PUSCH/PDSCH, all arrowbands or the part that can be preset as in system bandwidth
Arrowband, such as, can determine the available arrowband set according to cell ID and/or system bandwidth, than
Such as can use the number of arrowband for the half of the corresponding arrowband of system bandwidth, position is system bandwidth both sides arrowband.
Such as 20MHz systems, 16 arrowbands altogether, from frequency it is minimum to highest numbering be 0,1,2 ...,
15, then the arrowband number in the available arrowband set of PUSCH/PDSCH is 8, then can be with narrow
Band collection is combined into 0,1,2,3,12,13,14,15, or can also be according to cell ID
There is certain arrowband skew, such asFor 1, then to one arrowband of middle skew, you can with set
For 1,2,3,4,11,12,13,14,15.
The available arrowband set can also be the arrowband of eNB configurations, such as in SIB (System
Information Block, system information block) the middle arrowband for configuring PUSCH/PDSCH, or use UE
Special RRC (Radio Resource Control, wireless heterogeneous networks) signaling is that UE configures arrowband.
Before UE receives the RRC signaling of the information comprising available arrowband set of eNB transmissions, arrowband can be used
Set is default or the arrowband set that notifies in SIB, receives the bag of eNB transmissions in UE
After the RRC signaling of the information containing available arrowband set, UE is using the available arrowband set as oneself
Available arrowband set.
(1) method to determining the arrowband of physical channel is illustrated, and the physical channel includes：Thing
The shared letter of reason Uplink Shared Channel PUSCH (Physical Uplink Shared Channel), physical down
Road PDSCH (Physical Downlink Shared Channel), Physical Downlink Control Channel, physics with
Machine accesses channel PRACH (Physiacal Random Access Channel).
In the present embodiment, the physical channel can carry out frequency hopping repetition transmission, and UE can be according to this reality
The arrowband of the physical channel determined in applying example sends or receives to obtain UE the arrowband of the physical channel.
Specifically, the arrowband of the physical channel can be received as user terminal or sends the physical channel
The corresponding arrowband of initial subframe；Or can be calculated according to the arrowband of the physical channel and frequency pattern
The arrowband gone out after frequency hopping, the arrowband after the frequency hopping is received as user terminal or is sent the physics letter
The arrowband in road.
Two kinds of computing formula of frequency pattern are given below：
Frequency hopping computing formula one：
Wherein, m be the physical channel arrowband index, nfAnd nsfThe nothing that respectively physical channel is located
Line frame index, subframe index, formula of the f () for frequency pattern,It is physical channel in radio frames nfWith
Subframe nsfThe arrowband index of upper transmission.According to m, nf,nsfCan calculate in radio frames nfWith subframe nsfOn connect
Transmit/receive and send the arrowband of the physical channel to index.
Frequency hopping computing formula two：
mk=g (mk-1) (1-2)
Wherein, mk-1For the arrowband index that physical channel before frequency hopping is located, mkFor physical channel institute after frequency hopping
Arrowband index, formula of the g () for frequency pattern.Such as, UE is in subframe 0,1,2,3,4
PUSCH is sent on arrowband #0, PUSCH is sent on arrowband #1 in subframe 5,6,7,8,9,
So mk-1=0, mk=1.m0Arrowband for the physical channel is indexed.
For the formula (f (), or g ()) of frequency pattern, the embodiment of the present invention is not limited.
Below by taking PUSCH as an example for clearly determine physical channel arrowband method.Other physical channels
It is similar.
If the method that UE can be provided according to embodiments of the present invention determines that the PUSCH of the UE is located
Arrowband, then dispatch and the instruction of arrowband may not necessarily be included in the Downlink Control Information of the PUSCH believe
Breath, and distribution information of the PUSCH in arrowband is only included, so as to save instruction expense, in coverage enhancement
Under scene, the number of repetition of Downlink Control Information can be reduced.
The arrowband of PUSCH can be determined according at least one of：
A) refer to arrowband；
B) the available arrowband set of the physical channel；
C) mark of user terminal；
D) cell ID of the cell that user terminal is located；
E) send or receive the wireless frame index of the radio frames at the given sub-frame place of the physical channel；
F) send or receive the subframe index of the given sub-frame of the physical channel；
G) random access guiding preamble, the transmission preamble for sending during user terminal Stochastic accessing
Time-domain resource or send the frequency domain resource of the preamble；
It is exemplified below.Following determination modes are not limited in practical application.
Assume that the arrowband number in the available arrowband set of PUSCH is N, by this N number of arrowband according to frequency
Rate order from low to high is renumbered as 0,1 ..., N-1.The PUSCH is described available narrow
It is n with the arrowband index in setpusch, the arrowband index that the Downlink Control Information is located is nc。
The arrowband that PUSCH is located can be by least in cell ID, wireless frame index, subframe index
Individual determination, wherein, the wireless frame index is the given sub-frame place that user terminal sends the PUSCH
Radio frames wireless frame index, the subframe index is the specified son that user terminal sends the PUSCH
The subframe index of frame；Wherein, the given sub-frame can be the initial subframe of the PUSCH, but not
It is limited to the initial subframe of the PUSCH.
Alternatively, the arrowband that PUSCH is located can be by carrying out modulo operation determination to cell ID；
For example,
Wherein,For cell ID, mod is modulo operation (namely complementation computing), and N is available narrow
With the arrowband number in set；
Alternatively, PUSCH be located arrowband can by introduce random function, using wireless frame index,
The combination of subframe index or wireless frame index and subframe index is produced：
For example,
Wherein c (i) is a pseudo-random sequence, and j can be indexed for radio frames, subframe index, or described
The combination 10n of wireless frame index and subframe indexf+nsf, wherein, nfFor wireless frame index, nsfFor subframe

Here the example of pseudo-random sequence c (n) is provided, c (n) is produced by the Gold sequence of 31 length：
C (n)=(x1(n+NC)+x2(n+NC))mod2
x1(n+31)=(x1(n+3)+x1(n))mod2
x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2 (2-3)
Here NC=1600, it is a constant, first m-sequence for being used to produce pseudo-random sequence is adopted
x1(0)=1, x1(n)=0, n=1,2 ..., 30 initialize；Second m sequence for being used to produce pseudo-random sequence
Row are initialized using at least one of cell ID, UE marks, wireless frame index, subframe index,
Such as,Or
cinit=nC- RNTI, wherein, nC-RNTI(C-RNTI of UE) is identified for UE, M is preset value,
This mode is not limited in practical application.
Alternatively, except RACH, the arrowband of other physical channels can with by the UE with
