Description
Technical field
The present invention relates to communication technical field, in particular to a kind of method avoiding feedback message resource contention, one
Plant device, a kind of base station and a kind of terminal avoiding feedback message resource contention.
Background technology
With the development of mobile Internet, emerge the applied business meeting various specific functions in a large number.Some of them
Business is relatively low to data delay requirement, and such as receiving and dispatching mail downloads movies；But separately there are some business that data delay is had strictly
Requirement, such as network on-line plays, rushes to purchase, robbing red packet etc., and the time delay that this kind of business is usually required user data to the greatest extent may be used
Can short.With regard to how obtaining shorter user face data time delay, current lte (long term evolution, Long Term Evolution)
Two kinds of thinkings are mainly had, a kind of is that (transmission time interval sends using shorter tti in standard discussion
Time interval), that is, data transmit-receive interval adopts the tti more shorter than current 1ms, to reduce data processing time delay；Another kind is
For the terminal of highest version, support shorter data processing time delay in the case of 1ms tti to reduce harq (hybrid
Automatic repeat request, mixed automatic retransfer agreement) waiting time of feeding back.For example in current lte fdd
In (frequency division duplexing, FDD) system, the downlink data that descending sub frame n sends, need
Corresponding ack/nack feedback just can be received to sub-frame of uplink n+4, and the terminal of highest version has the data processing of higher performance
Ability, thus it is possible to shorten this feedback delay, for example can be in sub-frame of uplink n+3 with regard to ack/nack can be carried out
Feedback.
It is possible to the harq ack/nack supporting 4-m ms (m >=1) under 1ms tti occurs in following lte network
Highest version ue (user equipment, user terminal) of feedback delay, and only supports current 4ms ack/nack feedback delay
Legacy ue situation about coexisting.In this case, the ack/nack message of two kinds of different ue is it may happen that resource is rushed
Prominent, it is described as follows:
In lte system, in the case that ue does not have upstream data information to need simultaneous transmission, ue is directed to base station descending
The downlink data that subframe n sends, its corresponding ack/nack feedback message is placed on the pucch (physical of sub-frame of uplink n+4
Uplink control channel, physical uplink control channel) middle (it is assumed that using pucch format 1) transmitted,
The resource that pucch takies calculates according to below equation:
npucch=ncce+n(1) pucch；
Wherein, ncceCorrespond to dci (the downlink control that this ue is issued in base station in descending sub frame n
Information, downlink control message) shared by first cce (control channel element, control channel list
Unit) numbering.n(1) pucchIt it is one of base station high-level signaling configuration for the general numerical value of full cell terminal.
If in subframe n, the numbering for first cce of the dci of the ue1 supporting 4ms feedback delay is ncce1,
In subframe n+m, the numbering for first cce of the dci of the ue2 supporting 4-m ms feedback delay is also ncce1, then according to upper
State computing formula, the same resource in sub-frame of uplink n+4 is all fed back by the ack/nack feedback information of two terminals.This
Sample is the formation of the feedback information resource contention of ue1 and ue2.
In correlation technique, such as proposing in 3gpp motion r1-167891 can be by n(1) pucchIt is set to ue-specific's
Parameter, to solve feedback information resource contention, has an independent n for each ue(1) pucchNumerical value, but due to each
Cce shared by the dci of terminal is uncertain, can produce with the difference of the factors such as the situation of dispatch terminal and subframe numbers
Changing, and how n is set(1) pucchNumerical value with ensure each ue be not in resource contention be still a complicated problem,
And do not provide feasible n in motion r1-167891 yet(1) pucchDesign, so still cannot efficiently solve feedback message
The problem of resource contention.
Therefore, feedback message resource contention how is avoided to become technical problem urgently to be resolved hurrily.
