Preferred embodiment 1

In the preferred embodiment, description is using 4 symbols as the long PUCCH format of recurring unit：

Assuming that long PUCCH uses uplink slot, and uplink slot has 14 symbols, wherein first symbol controls for downlink Symbol, second symbol are GAP, and the 1st symbol reciprocal is short PUCCH, and remaining symbol is the symbol that long PUCCH is used.

For the long PUCCH of small load, such as 1~2bit, any one following configuration mode may be used, and (these four are matched It sets in mode, the number of repetitive unit is configured by base station, and specific value is determined according to actual demand, such as covering is big It is small.)：

1, repetitive unit time domain size is 1 symbol, and frequency domain is 1 PRB, is repeated at least 4 times.

2, repetitive unit time domain size is 1 symbol, and frequency domain is 2 PRB, is repeated at least 4 times.

3, repetitive unit time domain size is 2 symbols, and frequency domain is 1 PRB, is repeated at least 2 times.

4, repetitive unit time domain size is 2 symbols, and frequency domain is 2 PRB, is repeated at least 2 times.

Above-mentioned four kinds of configuration modes, may be used any one following frequency-hopping mode：

1, frequency hopping successively between repetitive unit.For example, first repetitive unit, in low frequency end, second repetitive unit then exists Front end.

2, the continuous repetitive unit of N number of time domain is mapped in the identical PRB of low frequency end, and remaining M time domain continuously weighs Multiple unit is mapped in the identical PRB of front end.

In above-mentioned four kinds of configuration modes, repetitive unit all includes the RS codes for self-demarking code.RS code bits repeat list in each In first in the symbol of front.Further, the RS codes can be optimized by any one following mode：

1, continuous 2 repetitive units of the identical PRB of frequency domain, time domain, first repetitive unit configure RS, and second repetition is single Member deletes RS (not configuring or do not include RS), and so on.The resource unit (RE) of RS is deleted in repetitive unit to be made With for long PUCCH.

2, continuous 3 repetitive units of the identical PRB of frequency domain, time domain, the 2nd repetitive unit configure RS, the 1st and 3 repetition Element deletion RS, and so on.The resource unit (RE) that RS is deleted in repetitive unit is used as long PUCCH.

In short, the identical PRB of frequency domain, when continuous repetitive unit (such as continuous 2 or more) occurs in time domain, part repeats Unit is instructed to or arranges not configure RS.Or the identical PRB of frequency domain, the symbolic number that the repetitive unit that time domain occurs includes are relatively more When, when being greater than 3, then allow in other symbols in repetitive unit other than first symbol to include RS.

Preferred embodiment 2

In the preferred embodiment, the resource distribution of long PUCCH should abide by following principle：

The time-domain symbol of long PUCCH meets covering and requires as far as possible, then carries out frequency domain resource extension again；

For the size of the time domain repetitive unit of long PUCCH, it should according to uplink symbol can be used in the slot of actual bearer It is determined.

For example, the symbolic number that can be used for long PUCCH in slot is 10, and the covering that 10 symbols meet long PUCCH is wanted It asks, then the repetitive unit time domain size that base station can configure long PUCCH is 5 symbols, and number is 2；The of this duration PUCCH One repetitive unit can be carried on identical PRB, and second repetitive unit can be carried on other identical PRB, To realize the frequency hopping between repetitive unit.

For example, the symbolic number that can be used for long PUCCH in slot is 8, and 8 symbols meet the covering requirement of long PUCCH, The repetitive unit time domain size that then base station can configure long PUCCH is 4 symbols, and number is 2；The first of this duration PUCCH A repetitive unit can be carried on identical PRB, and second repetitive unit can be carried on other identical PRB, with Realize the frequency hopping between repetitive unit.

For example, the symbolic number that can be used for long PUCCH in slot is 4, and 4 symbols meet the covering requirement of long PUCCH, The repetitive unit time domain size that then base station can configure long PUCCH is 2 symbols, and number is 2；The first of this duration PUCCH A repetitive unit can be carried on identical PRB, and second repetitive unit can be carried on other identical PRB, with Realize the frequency hopping between repetitive unit.

For example, when the symbolic number that can be used for long PUCCH in a slot is more than the symbolic number of actual (tube) length PUCCH, i.e., When the symbol that time domain can also use is long PUCCH, then in frequency domain, which can only use 1 PRB or 2 PRB.Phase With in time domain scale, the repetitive unit of same long PUCCH does not allow to repeat in frequency domain.

For example, the symbolic number that can be used for long PUCCH in slot is 11, and the covering that 11 symbols meet long PUCCH is wanted It asks, then the repetitive unit time domain size that base station can configure long PUCCH is 5,6 symbols, and number is 2；This duration PUCCH's First repetitive unit includes 5 symbols, can be carried on identical PRB, and second repetitive unit includes 6 symbols, energy It is carried on other identical PRB, to realize the frequency hopping between repetitive unit.

For example, the symbolic number that can be used for long PUCCH in slot is 9, and 9 symbols meet the covering requirement of long PUCCH, The repetitive unit time domain size that then base station can configure long PUCCH is 4,5 symbols, and number is 2；The of this duration PUCCH One repetitive unit includes 4 symbols, can be carried on identical PRB, and second repetitive unit includes 5 symbols, can quilt It is carried on other identical PRB, to realize the frequency hopping between repetitive unit.

For example, the symbolic number that can be used for long PUCCH in slot is 7, and 7 symbols meet the covering requirement of long PUCCH, The repetitive unit time domain size that then base station can configure long PUCCH is 3,4 symbols, and number is 2；The of this duration PUCCH One repetitive unit includes 3 symbols, can be carried on identical PRB, and second repetitive unit includes 4 symbols, can quilt It is carried on other identical PRB, to realize the frequency hopping between repetitive unit.

Preferred embodiment 3

In the preferred embodiment, the determination method of the repetitive unit in slot is described.

When the symbolic number that can be used for the long PUCCH of uplink in a slot is more than the symbolic number that actual (tube) length PUCCH is used, The position of this duration PUCCH determines in following manner：

The long PUCCH symbolic numbers actually used should be divided at least two repetitive units (actually this principle by base station It can be with unrestricted above-mentioned condition, it is possible to be described as including at least 2 repetitive units in a slot being long PUCCH.Such as Can include at this time a weight in slot when the symbolic number of repetitive unit, which is equal to, can be used for the symbolic number of long PUCCH in slot Multiple unit.).Two repetitive units are located in slot the both ends of total symbol workable for long PUCCH, are not made by long PUCCH Symbol is located at the centre of two repetitive units；Alternatively, two repetitive units total symbol workable for long PUCCH in slot One end, start to other end Continuous Mappings.

When PUCCH one long needs multiple slot, such as 2 slot, and it is all for long PUCCH in first slot The symbolic number used is insufficient to the symbolic number demand of long PUCCH, the symbol used for long PUCCH in second slot also not by All in use, base station can configure long PUCCH, there are at least two repetitive units in each slot by long PUCCH.

Preferred embodiment 4

In the preferred embodiment, the repetitive unit that base station configures same long PUCCH has identical size in frequency domain.

The repetitive unit that base station configures same long PUCCH is mapped in frequency domain without repeating, i.e., in identical time domain scale, one A repetitive unit no longer allows to be mapped again in frequency domain (except frequency hopping, because frequency hopping is not after frequency domain mapping is primary Same time domain scale).

When one vice-minister's PUCCH transmission, base station determines that resource is：It determines that time domain needs symbolic number in total, determines repetitive unit Time domain size encodes information to be transmitted according to constant bit rate k, and determines frequency domain resource PRB numbers, determines repetitive unit Number of repetition m, final PUCCH transmission code rates are k/m, and m can take 1, i.e., corresponding only to send a repetitive unit, without weight It is multiple.

Preferred embodiment 5

Base station is the size and number and frequency domain resource PRB numbers for the repetitive unit that UE configures long PUCCH.It base station can It is sent to by physical layer signaling, such as Downlink Control Information (such as in uplink authorization information therein) carrying above-mentioned parameter UE, UE receive the above-mentioned parameter that base station is sent, and determine the resource of long PUCCH；

Alternatively, base station is sent to UE by high-level signaling, such as RRC information to carry above-mentioned parameter, UE receives base station hair The above-mentioned parameter sent determines the resource of long PUCCH；

Alternatively, base station configures the big small set of repetitive unit time domain that UE can be used by high-level signaling, then pass through object Reason layer signaling indicates that specific repetitive unit time domain size, remaining parameter are carried still through physical layer signaling from set.

Preferred embodiment 6

Total symbolic number of long PUCCH is probably due to the position of UE is different, the symbol for causing the long PUCCH of different UE total Length is different, such as the more symbols of needs of cell edge are long PUCCH.For the ease of the resource of the long PUCCH of different UE Distributing uniform, and be conducive to remaining symbol and recycle, in the preferred embodiment, the resource allocation of long PUCCH should be abided by Following principle：

In slot, whether the symbol of long PUCCH is unified is distributed forward from a certain symbol at the ends slot, here comprising short Agreement or signaling instruction (including physical layer signaling or high-level signaling instruction) may be implemented in the symbol of PUCCH.For example, a certain UE Long PUCCH need 4 symbols or a repetitive unit being made of 4 symbols, then the long PUCCH of UE is from penultimate Symbol (including) start forward distribution (such as assume last symbol be short PUCCH, and long PUCCH do not include short PUCCH symbol Number；Or the long PUCCH of UE is distributed forward since the last symbol (including) of slot).Remaining symbol in slot in this way It number will be used for transmission the data of Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH), base station It can utilize in existing technology and configure the character position that its PUSCH terminates for UE, can thus long PUCCH be utilized not have The symbol transmission PUSCH of occupancy.I.e. long PUCCH from the ends slot configuration symbols forward, PUSCH from slot uplinks beginning to Configuration symbols (prior art) afterwards can make full use of resource with the maximum reuse prior art in this way.

Preferred embodiment 7

In slot, since the slot symbols for including are used for Downlink Control Information, GAP, upstream data, short PUCCH etc., And the symbolic number that Downlink Control Information occupies may be that (upper limit is 2 to 0~2 symbol at present, but is also possible to variation, example Such as 3), GAP (at present according to a symbol plan, it is also possible to be less than a symbol), short PUCCH also have can occupy it is more Symbol (for example, when the short PUCCH of multiple UE time division multiplexings).So when slot includes 7 or 14 symbols, length is left for The symbolic number of PUCCH is variation, and position is also variation.For the ease of the design of long PUCCH, in this preferred embodiment In, propose that (or base station passes through signal deployment, semi-static RRC information or physical layer signaling or both by base station and UE agreements In conjunction with) the primary sign position of long PUCCH (it can forward be calculated from primary sign position, it can also be from initial position to pusher It calculates, specifically any to arrange or configure).For example, for the slot of 7 symbols, long PUCCH is always accorded with from the 4th Number start to originate, calculates symbol backward；For another example, long PUCCH or repetitive unit include 4 symbols, then are exactly the 4th, 5,6,7 for length The symbol of PUCCH should allow long PUCCH to occupy the symbol of short PUCCH at this time, alternatively, not having short PUCCH in the slot； For another example, the slot of 14 symbols, long PUCCH are always originated from the 4th sign-on, calculates symbol backward；For another example, long PUCCH or repetitive unit include 4 symbols, then be exactly the 4th, 5,6,7 be long PUCCH symbol, long PUCCH should be allowed at this time The symbol of short PUCCH is occupied, alternatively, there is no short PUCCH in the slot.

For a long PUCCH, base station can configure its primary sign, and arrange from primary sign forward still backward Calculate the symbolic number of long PUCCH.Symbol after configuration primary sign before slot calculates the symbolic number of long PUCCH (in other words Be configured with the terminating symbol of long PUCCH, several symbols before terminating symbol are that long PUCCH is occupied), be conducive to avoid due to The symbolic number of Downlink Control Information changes the influence for the long PUCCH primary signs of fixation.Such as fixed the 4th symbol from slot Number start long PUCCH, if Downlink Control Information occupies a symbol in slot, GAP occupies a symbol, at this time the 3rd symbol Number do not occupied again by long PUCCH, there is waste, or to upstream data in use, so that become complexity (symbolic number is few, it is difficult to Upstream data is sent with smaller expense).

Preferred embodiment 8

Fig. 5 is that mapping pattern of the repetitive unit being made of 2 symbols in the slot structures of the above behavior master is shown It is intended to；Fig. 6 is mapping pattern signal of the repetitive unit being made of 2 symbols in the slot structures based on pure uplink Figure.

As shown in Figure 5 and Figure 6, the long PUCCH of different UE by frequency division or time-division or code division multiplexing together.It is long in Fig. 5 The repetitive unit of PUCCH, as primary sign, starts forward to calculate PUCCH symbols in slot from penultimate symbol.Example If the primary sign of UE1, long PUCCH are that (in primary sign, base station also needs to indicate or arranges to repeat penultimate symbol Unit is to be mapped since which side, such as the repetitive unit of UE1 should be instructed to originate mapping, such as UE2 from high band side Repetitive unit should be instructed to originate from lower frequency side map), repetitive unit size is 2, number 4, and each repetitive unit Between frequency hopping.

Base station can configure symbolic number and position in slot for long PUCCH.Such as it can be used to grow in a certain slot The symbolic number of PUCCH is 10 (being also completely used for long PUCCH including entire slot symbols), and is uplink part in slot Rear (or preceding) 10 symbols, and (Yes/No) including the short regions PUCCH.

Further, base station can configure the symbolic number that long PUCCH is used in slot and position and corresponding frequency domain position It sets.Frequency domain position can be described as subband or PRB.Example based on the preceding paragraph further increases frequency domain description, for example, description Frequency domain configuration for the long PUCCH of the preceding paragraph is happened at subband 0.It is different for growing in different sub-band, allowing to configure The symbolic number of PUCCH and position.Which PRB example, the frequency domain configuration for being described as the long PUCCH of the preceding paragraph are happened in again.

Obviously, symbolic number and position and frequency domain position simultaneously in a slot when, then allow in slot, in difference Frequency domain position (subband or PRB in) in the corresponding long PUCCH symbolic numbers of configuration and position.Such as in slot, in subband 0 The symbolic number and position that the long PUCCH of configuration is used in (or one group of PRB)；Configured in subband 1 symbolic number that long PUCCH is used and Position.

Obviously, symbolic number and position and frequency domain position simultaneously in a slot when, then allow in slot, exist not It is frequency division multiplexed with a long PUCCH between frequency domain position or the different long PUCCH of same frequency domain position is division multiplexed.For example, Base station configures in subband 0 (or one group of PRB), and it is a UE that long PUCCH, which occupies 10 symbols, while in subband 1, long PUCCH 10 symbols are distributed respectively to the long PUCCH time division multiplexings of 2 UE, they occupy 5 symbols respectively, when also admissible mark intersects Point.Here 10 symbols in subband 0 and subband 1 can be identical symbol.

In the repetitive unit of same size, the long PUCCH of different UE is allowed to carry out code division multiplexing.

In the application, the technical characteristic in each embodiment can be combined in one embodiment in the absence of conflict Middle use.Each embodiment is only the optimal embodiment of the application, is not used to limit the protection domain of the application.
