At least one PRB, be reserved as the 4th resource according to format1/1a/1b format transmission PUCCH.
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
As shown in fig.3, providing a kind of eMTC PUCCH resource method for obligating in the embodiment of the present invention, detailed process is such as
Under:
Step 300: being directed to legacy user (hereinafter referred to as Legacy user), frequency band two sides most marginal at least one will be located at
A PRB is reserved as the first resource according to format2/2a/2b format transmission PUCCH.
Specifically, as shown in fig.4, PRB all in the most marginal location A in two sides above and below frequency band is reserved as first
Resource is used for transmission the PUCCH of format2/2a/2b format.
During above-mentioned reserved first resource, further, it is also necessary to determine the Legacy user accessed in system
Number, and Legacy number of users is carried out to take idol upwards, the first even number is obtained, then, according to the first even number, at each
Reserve above-mentioned first resource in the frequency band two sides of gap, wherein first resource is equal in the number of resources that frequency band two sides are distributed.
It is so-called to take idol upwards, in the embodiment of the present invention, if Legacy number of users is odd number, take upwards it is even for greater than
The minimum even number of the odd number, if Legacy number of users is even number, taking upwards even is the even number itself.
For example, it is assumed that being currently accessed 3 Legacy users in the system of determination, then Legacy number of users is taken upwards
Even, obtaining the first even number is 4, it is assumed that determine and be currently accessed 6 Legacy users in system, then to Legacy number of users to
On take idol, obtaining the first even number is 6.
By take upwards it is even after the first resource that distributes symmetrically be distributed in frequency band both sides of the edge, and due to
Legacy user use time domain between frequency-hopping mode transmission format2/2a/2b format PUCCH, and eMTC user cannot using when
The PUCCH of frequency-hopping mode transmission format2/2a/2b format between domain, therefore, in resource reserved for Legacy user, using to
On take even mode that the PUCCH of each user can be made to configure reasonable resource, avoid Legacy user and eMTC user
Resource clashes.
For example, be Legacy user 0 respectively as shown in fig.5, be currently accessed 3 Legacy users in hypothesis system,
1,2, the first even number of acquisition is 4, then in a sub-frame of uplink, Legacy user 0 occupies slot0 midband most edge side
The running time-frequency resource of m=0, while Legacy user 0 occupies the most marginal other side of slot1 midband using frequency-hopping mode between time domain
The running time-frequency resource of m=0, likewise, frequency-hopping mode band occupancy between time domain is respectively adopted in Legacy user 1 and Legacy user 2
The running time-frequency resource of m=1, m=2 of two sides, although and the running time-frequency resource of m=3 be vacant resource, the vacant resource be frequency hopping sky
It is remaining, it is only used for the PUCCH that the Legacy user of frequency hopping between time domain is supported in transmission, cannot be reserved as using continuously transmitting mode
The PUCCH of eMTC user therefore use and even mode taken to reserve first resource for Legacy user upwards, can be to avoid
The resource of Legacy user and eMTC user clash.
Step 301: be directed to eMTC user, by be located at first resource on the inside of at least one PRB, be reserved as according to
The Secondary resource of format2/2a/2b format transmission PUCCH, also, at least one PRB on the inside of Secondary resource will be located at, in advance
It is left the information resources according to format1/1a/1b format transmission PUCCH.
Specifically, as shown in fig.4, being reserved as the second money for all PRB in the B location on the inside of first resource are located at
Source is used for transmission the PUCCH of format2/2a/2b format.
Wherein, if the last one PRB in Secondary resource is not taken by the PUCCH of format2/2a/2b format,
Two, resource interval cyclic shift in the last one PRB in two resources, with the PUCCH of carrying format2/2a/2b format
After sequence, surplus resources are reserved as the information resources according to format1/1a/1b format transmission PUCCH.
For example, as shown in fig.4, in Secondary resource, if B2The last one PRB in position is not by format2/
The PUCCH of 2a/2b format takes, then after the PUCCH of format2/2a/2b format, is being spaced two cyclically shifted sequences
Start according to format1/1a/1b format transmission PUCCH, that is, by B2When frequency domain resource in position is reserved as Secondary resource, also
Information resources can be reserved in the last one PRB.
After reserving Secondary resource, as shown in fig.4, by all PRB in the location of C on the inside of Secondary resource are located at,
It is reserved as the information resources according to format1/1a/1b format transmission PUCCH.
During above-mentioned reserved Secondary resource and information resources, further, it is also necessary to determine and be accessed in system
EMTC number of users, and to eMTC number of users carry out it is whole take idol upwards, obtain the second even number, then, according to the second even number,
Secondary resource and information resources are reserved in frequency band two sides, wherein in frequency band Secondary resource and information resources that wherein side is distributed
Total number resource be equal to the frequency band other side distribution Secondary resource and information resources total number resource.
For example, it is assumed that being currently accessed 3 eMTC according to format2/2a/2b format transmission PUCCH in the system of determination
User, respectively eMTC user 4,5,6, have accessed 4 eMTC users according to format1/1a/1b format transmission PUCCH, point
Not Wei eMTC user 7,8,9,10, then idol taken upwards to eMTC total number of users mesh 7, obtaining the second even number is 8.In uplink
In frame, eMTC user 4,5,6 occupies the running time-frequency resource of m=4, m=5, m=6 respectively, for the running time-frequency resource of m=7, due to
EMTC user is by the way of continuously transmitting, and therefore, in order to avoid the wasting of resources, the running time-frequency resource of m=7 can be kept for eMTC
User 7, likewise, eMTC user 8,9,10 occupies the running time-frequency resource of m=8, m=9, m=10 respectively, and the time-frequency of m=11 provides
Source is vacant resource, since Legacy user uses time-domain frequency-hopping transmissions, cannot be given the vacant resource reservation of m=11
Legacy user is used for transmission PUCCH, therefore, using eMTC number of users is integrally taken upwards it is even by the way of reserve Secondary resource
And information resources, resource can be reasonably distributed, the wasting of resources is avoided.
On the other hand, for eMTC user, it is also necessary to for downlink signaling 4 (Message4, MSG4) it is reserved according to
The resource of format1/1a/1b format transmission PUCCH, the format of MSG4 are format1/1a/1b, can access system according to MSG4
The covering grade of system is reserved in information resources.
For example, needing to transmit affirmative acknowledgement or no when Secondary resource is reserved in the outside of first resource for eMTC user
Determine response (Acknowledgement/Negative Acknowledgement, ACK/NACK), wherein "/" indicates "or",
In order to guarantee that the corresponding ACK/NACK of the corresponding ACK/NACK and Legacy user of eMTC user does not conflict, it is therefore desirable to according to covering
Lid grade is that the MSG4 of eMTC user reserves resource.
Firstly, being directed to the MSG4 of eMTC user, the number of covering grade in MSG4 is determined.
For example, being directed to eMTC user, different number of retransmissions corresponds to different covering grades, it is assumed that MSG4 corresponding 4 cover
Lid grade, then covering grade number is 4.
Secondly, calculating the corresponding control letter of a covering grade according to the PRB number that the corresponding covering grade of MSG4 includes
Road element (Control Channel Element, CCE) number.
For example, it is 2 CCE that the PRB number that the corresponding covering grade of MSG4 includes, which is 6,1 PRB, then it is calculated each
The corresponding CCE number of covering grade is 12.
Again, it is based on covering grade number and the corresponding CCE number of each covering grade, all covering grades is calculated and occupies
CCE total number.
For example, covering grade number is 4, the corresponding CCE number of each covering grade is 12, then all covering grades occupy
CCE total number be 48.
Finally, according to CCE total number, in information resources, for the reserved resource for being used for transmission PUCCH of MSG4.
For example, it is assumed that it includes 12 subcarriers on 1,1 PRB that each PUCCH cyclic shift number, which is, on each subcarrier
1 PUCCH can be carried, in order to enable each PRB to carry more PUCCH, can using orthogonal code 3 to each PUCCH into
Row conversion, makes that 36 PUCCH can be carried on each PRB, and the CCE total number that downlink MSG4 is occupied is 48, therefore, accordingly
It needs to reserve enough resources for carrying 48 PUCCH in feedback result, then divided by 36 and is rounded up, tied with 48
Fruit is 2, then in information resources, need for MSG4 it is reserved to be used for transmission the PRB number of PUCCH be 2, for the reserved MSG4 of user
When resource, it can transfer 2 PRB in information resources in the way of dynamic dispatching and be reserved.
Step 302: be directed to Legacy user, by be located at information resources on the inside of at least one PRB, be reserved as according to
The 4th resource of format1/1a/1b format transmission PUCCH.
Specifically, as shown in fig.4, being reserved as the 4th money for all PRB in the position D on the inside of information resources are located at
Source is used for transmission the PUCCH of format1/1a/1b format.
Mode same as first resource is reserved in step 300, during reserved four resource, it is also desirable to determine system
The Legacy number of users accessed in system, and Legacy number of users is carried out to take idol upwards, it obtains the first even number and then presses
According to the first even number, above-mentioned 4th resource is reserved in the frequency band two sides of each time slot, wherein the 4th resource is distributed in frequency band two sides
Number of resources it is equal.
For example, it is assumed that being currently accessed 2 Legacy users in the system of determination, then Legacy number of users is taken upwards
Even, obtaining the first even number is 2.
By taking even the 4th resource distributed later symmetrically to be distributed in frequency band both sides of the edge upwards.
For example, being Legacy user respectively as shown in fig.5, be currently accessed 2 Legacy users in hypothesis system
12,13, the first even number of acquisition is 2, then in a sub-frame of uplink, although m=11 is vacant resource, Legacy user
12 cannot occupy the running time-frequency resource of m=11, and Legacy user 12 occupies the running time-frequency resource of slot0 midband most inner side m=12, together
When the symmetrical other side m=12 of slot1 midband running time-frequency resource, likewise, 13 band occupancy two sides m=of Legacy user
13 running time-frequency resource.
It is respectively the first resource and Secondary resource that Legacy user distributes transmission PUCCH using the above method, is eMTC
User distributes the information resources and the 4th resource of transmission PUCCH, during transmitting PUCCH resource, according to accessing user's
Transformat is dispatched accordingly.
