Feature, element, function or part.
For the ease of explaining, herein by with the low complex degree in LTE system and/or coverage enhancement MTC device as background
Embodiment of the disclosure is introduced, however, as will be understood by the skilled person in the art, embodiment of the disclosure is not limited to LTE
The applied environment of MTC, conversely, and can be to be applied in any communication system that there are Similar Problems.
Fig. 1 is shown in which the schematic diagram of the cordless communication network that can implement embodiment of the disclosure.Merely for explanation
Purpose, cordless communication network 100 is shown as honeycomb in Fig. 1.However, it will be appreciated by those skilled in the art that this public affairs
The embodiment opened is equally applicable to other network structures, such as, MANET (ad hoc), as long as wherein there is a problem of similar.
The cordless communication network includes one or more base station 101, merely for example purpose, the base station is shown as into 3GPP LTE systems
Enhanced node B (eNB, or eNodeB) in system.It is appreciated that the base station can also adopt node B (NB), base station subsystem
The forms such as system (BSSs), relay station.Base station 101 is that multiple wireless devices (such as 102-104) provide wireless connection, and this wirelessly sets
Standby can be user equipment (UE).Term " user equipment " is also known as mobile communication terminal, wireless terminal, mobile station, machine
Type communication (MTC) equipment etc., and including mobile phone, intelligent electric meter, sensor, wearable device, with radio communication
Computer of ability etc..The UE is probably low complex degree equipment (LC UE), and/or needs the equipment (CE UE) of coverage enhancement.
In current LTE system, base station is by under physical downlink control channel (PDCCH) or enhanced physics
Uplink Control Channel (EPDCCH) to UE sends scheduling message, and the scheduling message can be indicated for downlink transmission
Physical down link sharing channel (PDSCH) resource etc..HARQ is supported in LTE, that is to say, that receive in PDSCH
After the downlink data of base station, UE is needed in uplink feedback ACK or NACK, and the feedback can physically row chain
Transmission in road control channel (PUCCH).
Have agreed in 3GPP RAN1#82 meetings, LC equipment and CE equipment can support PUCCH format 1/1a/2/
2a, and according to identical mode specified in LTE Rel-12 versions deriving PUCCH resource, i.e., by PDCCH or
EPDCCH is determining PUCCH resource.With regard to the determination of PUCCH resource in existing LTE standard, may refer to
10th chapter of TS36.213V12.2.0 (in June, 2014).
Reuse existing method, PUCCH resource is drawn by PDCCH/EPDCCH with its advantage, for example, to standard
Affect little.But, the program is when LC and CE equipment is supported it is possible that problem.For example, according to LTE FDDs (FDD)
Existing method in system, it is assumed that the situation of an antenna port and a configuration cell, the distributed transmission for EPDCCH
(distributed transmission) and localized transmission (localized transmission), PUCCH resource
Can be according to parameter nCCE,ΔAROWithDetermine respectively, such as following formula (1) and (2) are shown：
For distributed transmission：
For localized transmission：
Wherein nECCEIt is the minimum rope of the enhanced control channel unit (ECCE) in the EPDCCH associated with the PUCCH
Draw, ΔAROCan be to determine in the HARQ-ACK resource offset fields from down link control information (DCI),Table
Show the number of the ECCE included in each Resource Block (RB),n'Downlink control channel to send the scheduling message is made
Determined by antenna port be worth, for example, can be found in TS36.213V12.2.0 (in June, 2014) the 10th chapter and
The 6.8A.5 sections of TS36.211V12.2.0 (in June, 2014), andIt is the starting point skew of PUCCH resource, is currently
Configured by high-level signaling.
However, for LC equipment and CE equipment, directly reusing existing method and determining that feedback resources will cause PUCCH to provide
The conflict in source.For example, as it was previously stated, LC UE work in certain subband in system bandwidth, if taking difference EPDCCH subbands
Two LC UE DCI assignment have the minimum ECCE indexes of identical, i.e. its nECCEValue it is identical, then according to more than (1) or
(2) formula is calculatedMay be identical.If this means that their PUCCH is located at same subband, PUCCH is likely to
Conflict.CE UE are equally likely to cause the conflict of PUCCH resource.It is assumed that two CE UE have different repetition levels, then exist
Time interval between its EPDCCH and PUCCH can be different, in this case, if their PUCCH is located at same subband,
Due to different time intervals, the EPDCCH in different subframes may be mapped to the PUCCH resource in same subframe, cause
The conflict of PUCCH resource.Schematically showing in fig. 2 is caused the scene of PUCCH conflicts by LC and/or CE UE.Wherein show
Go out, in the two examples above due to, the EPDCCH for causing 6 UE is mapped to same PUCCH resource, causes serious
Conflict.
Can be the different Δ in difference UE setting (1-2) formulas to solve above-mentioned collision problemARO, the ΔAROCan
HARQ-ACK resources offset field in the DCI format of corresponding EPDCCH determines, and can solve to a certain extent
Collision problem.But the value of the parameter is restricted to [0, -1, -2,2], it is limited that this causes it to solve the effect of conflict.For example
System bandwidth for 20MHz, may at most there is 16 arrowbands (it is assumed that the PRB sizes of each arrowband 6) in a subframe, by
In ECCE in each arrowband independent numbering, this cause in different narrow band be up to 16 UE there is identical nECCE, ΔAROHave
Limit value can not solve the problem.
In 3GPP meeting document R1-155113, it is proposed that for CE MTC UE can based on clear and definite high-level signaling come
The PUCCH resource position in arrowband is notified, to solve conflict.It is obvious that the program will bring very big signaling consumption.
In another meeting document R1-155302 of 3GPP, propose that the ECCE in difference DL arrowbands can be compiled continuously
Number such that it is able to reuse existing PUCCH resource mapping equation to derive PUCCH.Specifically, for DL MTC arrowbands 1,
, from 0 to X-1, for DL MTC arrowbands 2, ECCE indexes are from X to 2X-1 etc. for the index of ECCE.Wherein X parameter be it is predetermined or
Configured via high-level signaling in the specific mode of cell.The program can solve the problem that identical minimum ECCE ropes in different narrow band
The collision problem of the PUCCH resource for causing.But, due to carrying out serial number, cause the scope of the index of ECCE very big, this
Mean to reserve substantial amounts of PUCCH resource, cause the waste of PUCCH resource.
In another document R1-155346 of 3GPP, it is proposed for not repeating or a small amount of situation about repeating, based on most
The PRB indexes of PDSCH afterwards are determining PUCCH resource.When a large amount of repetition, the arrowband rope based on last PDSCH
Attract and impliedly determine PUCCH resource.Each MTC UE only indexes of the PRB with its last PDSCH.The method can keep away
Exempt from conflict, it is also larger yet with the scope of PRB indexes, equally also cause the waste of PUCCH resource.
In the disclosure, at least some problem in solving the above problems, it is proposed that new solution, with difference
Thinking solve the collision problem of feedback resources, and do not lose system effectiveness.
The flow chart of method for resource allocation 300 in accordance with an embodiment of the present disclosure is shown in fig. 3 a.The party
Method 300 for example can be performed in base station (such as the base station 101 in Fig. 1) side of wireless communication system, but the reality of the disclosure
A not limited to this is applied, because the method can also be by other suitable equipment (such as in non-cellular scene) in other scenes
To perform.
As shown in Figure 3 a, the method 300 includes：In block S301, sent to equipment by downlink control channel and dispatched
Message, the scheduling message is indicated for the resource of the device transmission down link data；In block S302, in indicated money
To device transmission down link data on source；In block S303, it is determined that for receiving for the anti-of down link data from the equipment
The uplink control channel resource of feedback, the wherein determination are at least based on the subframe in transmission scheduling message (for purposes of illustration only, claim
By the first subframe) in the polymerization level (AL) that uses of downlink control channel；And in block S304, by determined by
Uplink Control Channel resource receives the feedback from equipment.
In one embodiment, the wireless communication system can be LTE or lte-a system, and in block block S301
Downlink control channel for sending scheduling message can be EPDCCH, but embodiment of the disclosure not limited to this.
In another embodiment, the uplink control channel resource determined at the block S303 can be LTE in PUCCH resource, and
And the channel is used for ACK/NACK of the feedback for down link data.But as skilled in the art will understand, originally
Disclosed embodiment not limited to this, the uplink control channel resource can also be for the down link data to be carried out
Other channels of feedback.During only existing in succinctly and for illustrative purposes, hereinafter will mainly by taking EPDCCH, PUCCH as an example
To describe embodiment of the disclosure.
According to existing LTE standard, according in the channel conditions of particular device, in block S301, base station can select suitably
Sending scheduling message, each AL indicates the number for sending the ECCE of EPDCCH to AL.For example in current LTE AL=1 is supported,
2,4,8,16,32 (referring to Sections 6.8 of 3GPP specification TS 36.211V12.2.0 (in June, 2014)).But such as this area skill
Art personnel it will be appreciated that, embodiment of the disclosure be not limited to only use LTE system in existing AL values；For example implement at some
In example, other suitable AL values can be adopted, to be adapted to different wireless communication standards or its different editions.
Agree in 3GPP RAN1#82 meetings, cover or little coverage enhancement for normal, for MTC's
PDCCH (abbreviation M-PDCCH) can also have different AL.In order to be fully solved foregoing PUCCH resource conflict problem,
The scope of PUCCH resource skew sufficiently large must be indexed with accommodating all possible PUCCH resource.This is undoubtedly inefficiency
's.Particularly in view of n in practical implementationsECCEIt is only possible to take a small amount of possibility value.For example, for working in the case of CE
UE (for instance in the UE of poor channel condition), in order to reduce number of repetition, can only support larger AL.And 3GPP is advised
Model TS 36.213V12.2.0 are specified in (in June, 2014), including the EPDCCH of n continuous ECCE (that is, AL=n) only can
From the beginning of at numbering i for meeting i mod n=0, wherein i is the numbering of ECCE.When therefore for AL=8, UE is specific
The value of minimum ECCE indexes is nECCE=8k, wherein k are integers.The scene means nECCEECCE index values outside=8k
Corresponding PUCCH resource is not used, and this undoubtedly causes the waste of PUCCH resource.
In view of problem above, in one embodiment of the disclosure, can be set as that scheduling disappears by the position of PUCCH resource
The function of the AL used in the transmission subframe of breath.In one embodiment, the AL may be used to determine whether that PUCCH resource is relative
In the skew of PUCCH resource starting point, such as relative in formula (1)Skew.This makes it possible to consider specific AL
N during valueECCEPossibility value, so as to no longer be all of nECCEValue reserves PUCCH resource, so as to reduce the wasting of resources.
In one embodiment, can be the AL that the transmission of scheduling message is used for determining the AL of PUCCH resource.
In another embodiment, in same scheduling subframe, for different UE, base station can be used for using different AL
EPDCCH.In block S303, PUCCH can be determined based on the minimum AL used in the EPDCCH in the subframe for difference UE
The position of resource, i.e. PUCCH resource can be set to the function of minimum AL in corresponding EPDCCH subframes.
For example, AL or minimum AL (are expressed as ALmin) n that can be used to adjust in (1-2) formulaECCE,ΔARO,
The value of middle any one.For example can be by nECCEIt is adjusted to n'ECCE=nECCE/ALmin。
As skilled in the art will understand, the disclosure is not limited in block S303 with any specific function of AL
Form is determining PUCCH resource.Its principle be it is determined that during PUCCH resource, the information of AL is accounted for, with reduce conflict and
Reduce the wasting of resources.
In another embodiment, can include for the multiple narrow of downlink control channel in the wireless communication system
Band resource, and in block S303, additionally or alternatively, it is also based on the narrowband resource for sending the scheduling message
The index of (for purposes of illustration only, referred to as the first narrowband resource) in multiple narrowband resources is determining resource.That is, can be single
Both solely indexes based on used narrowband resource, or the index and AL based on the narrowband resource are determining feedback resources.
In one embodiment, in block S303, the rope of the PUCCH resource for feedback can in the following manner be calculated
Draw
If the downlink control channel is transmitted using distributed resource,
If the downlink control channel is transmitted using centralized resources,
WhereinnECCERepresent the minimum index for transmitting the ECCE of the scheduling message, ALminRepresent and sending the tune
Spend the minimum of a value of the AL that downlink control channel is used in all arrowbands in the subframe of message, nepdcch_NBidxRepresent and send
The index of the narrowband resource of the scheduling message, M represents the sum of the ECCE in each narrowband resource, narrow for 6PRB
Band, M=24；The number of the ECCE in a RB is represented,Represent rising for the uplink control channel resource
Initial point offsets, value determined by the antenna port that n' is used by the downlink control channel of the transmission scheduling message.
In one embodiment, n' can have and identical implication in (2) formula, but embodiment of the disclosure is not limited to this.In root
According to the principle of the disclosure, using ALminAnd nepdcch_NBidxIt is determined thatOn the basis of, can be using any suitable n' to true
Determining result carries out appropriate adjustment.
It is assumed that ALminIt is for 8, then possiblenECCEValue will be { 0,8,16 }.From different EPDCCH arrowbands with value
MTC UE for 8 or bigger AL only have a PUCCH resource.It is assumed that minimum AL is 24, then the possibility in an arrowband
'snECCEValue is only { 0 }.Equally, the MTC UE with the AL that value is 24 from different EPDCCH arrowbands also only have one
Individual PUCCH resource.As a example by transmitting in a distributed manner, it is shown respectively in table 1,2, in ALmin=8 and ALminIn the case of=24 two kinds,
(3) in formula front two sums value, i.e.,Value, orIn the case ofTake
Value.
Table 1.PUCCH resource allocations (bandwidth 20MHz, ALmin=8)
Table 2.PUCCH resource allocations (bandwidth 20MHz, ALmin=24)
Resource Allocation Formula set forth above is it is determined that introduce the arrowband index and AL values work of EPDCCH during PUCCH resource
For parameter, so as to ensure that conflict can be solved, while the level of resources utilization can be enhanced.Note, between different UE
When AL difference is larger, for example as shown in table 1, the AL=8 of some UE, and other UE AL=24 then causes some resources can not
Enough UEs higher by AL levels use (such as in table 1 UE of AL=24 only can compartment of terrain use resource 0,3,6,9 ...), lead
Cause the reduction of the level of resources utilization.Therefore, in certain embodiments, the value that base station can be configured in like the AL of UE.
It should be noted that above (3-4) formula is to be used in combination both the index of AL and narrowband resource to determine that PUCCH is provided
One specific example in source, but as skilled in the art will understand, embodiment of the disclosure is not limited to this, but
Any suitable deformation and modification can on this basis be carried out.In some embodiments, it is also possible to only using AL or arrowband
The index of resource is determining PUCCH resource.
In one embodiment, method 300 can also include, in block S310, AL be sent to equipment by signalingminIt is quiet
State or semi-static value.For example, base station can notify the value in system information, or by high-level signaling (for example
RRC signaling) notify the value to UE.In another embodiment, the ALminCan also be predetermined or can be implied by UE
What ground determined, without signaling.
As previously mentioned, for the UE with different repetition levels, the time interval between EPDCCH and corresponding PUCCH is not
Together, it is identical because of minimum ECCE values and cause the EPDCCH in different subframes to reflect if its PUCCH is located at same subband
Identical PUCCH is mapped to, causes resource contention.For this purpose, in another embodiment, alternatively or additionally, in block S303
In, uplink control channel resource can be determined based on the repetition levels used when sending the scheduling message.For example, may be used
With the zones of different residing for determining PUCCH according to different repetition levels, so as to avoid the above above in conjunction with shown in Fig. 2 by
In the caused PUCCH resource conflict of different repetition levels.
As an example, as shown in Figure 3 b, can include in block S303：In block S313, based on repetition levels uplink is determined
The starting point skew of road control channel resource, such as in formula (1-4)I.e. so thatWhen repetition levels letter
Number；And, in block S323, offset to calculate the index of uplink control channel resource based on the starting point.
In one embodiment,Can with possibility value can be by be predefined as：
OrAnd wherein each value can correspond to one or more repetition levels.Then base station can be according to making
