Description

Resource allocation method and device for allocating resources

Technical field

The present invention relates to communication technical field, fills in particular to a kind of resource allocation method and a kind of resource distribution Put.

Background technology

Existing 4G and 4.5G mobile communication technology, (Long Term Evolution, is drilled for a long time to be all based on LTE Enter) and the wireless access technology of LTE-A (LTE-Advanced), running time-frequency resource granularity and frame structure etc..Such as current LTE system The a width of 20MHz of maximum single carrier band that can support, to the bigger bandwidth of support, can only rely on carrier aggregation (Carrier Aggregation, abbreviation CA) use.In addition, current frame structure mainly includes：FDD(Frequency Division Duplexing, FDD) frame structure, TDD (Time Division Duplexing, time division duplex) frame structure and LAA The dynamic frame structure that (LTE Assisted Access, LTE auxiliary is accessed) unauthorized carrier wave is used.Regardless of frame structure, All include 10 subframes, each subframe is that 1ms, each subframe includes two slot (time slot), and a slot is 0.5ms, each Slot includes 7 symbol (symbol) again.In terms of frequency domain, in LTE system, subcarrier spacing is mainly 15KHz, a RB (Resource Block, Resource Block) contains 12 subcarriers.And in NB-IoT (Narrow Band Internet of Things, the arrowband Internet of Things based on honeycomb) in propose a kind of subcarrier spacing of new 3.75KHz again, and NB-IoT Carrier bandwidths only have 180KHz.

In terms of resource allocation, FDD frame structure and tdd frame structure be all with 1ms subframe as when domain scheduling granularity, except DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot) in special subframe in tdd frame structure is used for transmitting During data, when domain scheduling granularity be less than 1ms's.Same the unauthorized carrier wave of LAA using frame structure in also occur in that multiplexing DwPTS is used as the descending scheduling time domain granularity of partial subframe, while also using the scheduling granularity of the whole subframe of 1ms. And in FDD frame structure and tdd frame structure, except the existing down sending time of special subframe in tdd frame structure and up Send outside the time, or other subframes are all up transmission or descending transmission time domain and separating frequency domain and separating.

It can be seen that, the granularity of current frame structure and frequency domain resource can all cause resource allocation underaction, and uplink scheduling The time of mechanism and HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) feedback mechanism etc. Interval again causes that time delay is larger, and 20MHz bandwidth is also unsatisfactory for high bandwidth requirements.

Following 5G communication prevailing scenario includes following three kinds：EMBB (enhanced Mobile Broadband, enhanced Mobile broadband network), mMTC (massive Machine Type Communication, large-scale machines class communicate) and URLLC (Ultra-Reliable and Low Latency Communications, highly reliable low time delay communication).These three The targeted type of service of scene is different, and its demand is also different.Such as：Two leading indicators of eMBB business are high bandwidths And low time delay, on following high-frequency communication, eMBB business may support the big bandwidth of 100MHz, and be likely to sometime Whole bandwidth is all distributed directly to a user and uses, and uplink scheduling time delay and HARQ feedback time delay also bring along time delay shadow Ring；MMTC service needed is narrowband service, needs battery life very long, and this business is accomplished by the frequency domain of smaller particle size and more The time-domain resource of wide granularity；For URLLC business, it is also desirable to reduce the time delay that uplink scheduling time delay and HARQ feedback time delay are brought Impact.

That is due to the variation of business so that at present fixing frame structure, the frequency domain resource granularity of fixation and when Domain resource granularity can cause larger uplink scheduling time delay and longer HARQ feedback time delay, and less carrier bandwidths are also no Method meets the diversified demand of business, and 5G communication wants to accomplish enough flexibly, and any one resource all may be dynamic It is scheduling to use at any time.

At present, following common recognition has been reached in the council for 5G：For the different business on same carrier wave, can To there is different subcarrier spacings.If concrete as shown in figure 1, the subcarrier spacing of minimum is f₀, next has 2f₀、4f₀And 8f₀, The size of so corresponding RB (Resource Block, Resource Block) also becomes multiple proportion.In this case, such as UE#1 is used Be f₀, and only need to use f₀When RB0, and at this time without other use f₀User need Resources allocation, only use 2f₀UE#2, and UE#2 uses 2f₀When RB0 in part resource employed by UE#1, then remaining part resource Whether need UE#2 is distributed to, and how this designs which part of signaled UE#2 is used by other when UE#2 is distributed to It is all technical problem urgently to be resolved hurrily that family employs.

Content of the invention

The present invention is based at least one above-mentioned technical problem, it is proposed that a kind of new resource allocation proposal so that base When standing in the multiple terminal distribution resources being spaced using different sub carrier, maximally utilizing for resource, and energy is ensure that Enough accurate instruction terminals know the communication resource being assigned to.

In view of this, according to the first aspect of the invention, it is proposed that a kind of resource allocation method, including：Notify base station clothes The first subcarrier spacing that any terminal of business is used when communicating, and notify the base station to service to any terminal The second subcarrier spacing for using of other terminals；All terminal distribution communication resources to base station service；If to described Any terminal distribution its using the first subcarrier spacing under Resource Block in have part resource to be assigned to other terminals Use, then indicate the position of the Resource Block according to first subcarrier spacing to any terminal, and according to described the Two subcarrier spacings indicate to be assigned to, in the Resource Block, the part resource that other terminals are used to any terminal.

In the technical scheme, by the resource under its first subcarrier spacing for using that distributes to any terminal When having part resource to be assigned to other terminals uses in block, the resource of distribution is indicated to the terminal according to the first subcarrier spacing The position of block, and indicate in the Resource Block, to be assigned to the part that other terminals are used to the terminal according to the second subcarrier spacing Resource so that base station, can be according between different sub carrier when to the terminal distribution communication resource being spaced using different sub carrier Guarantee maximally utilizing for resource every corresponding Resource Block granularity, it is to avoid some is using the terminal of larger subcarrier spacing Only used a part of resource in larger Resource Block and remaining part resource is no longer allocated to the resource that other terminals are caused The problem of waste, improves spectrum efficiency.Meanwhile, also ensure that terminal can be accurate by indicating mode proposed by the present invention Know itself allocated communication resource, receive or send data by the allocated communication resource in order to terminal.

In technique scheme, it is preferable that second subcarrier spacing is less than or equal between first subcarrier Every, wherein, second subcarrier spacing is the minimum subcarrier spacing used in the terminal of base station service, or described the Two subcarrier spacings are only little than first subcarrier spacing subcarriers used in the terminal of base station service Interval.

In the technical scheme, when the second subcarrier spacing is the minimum subcarrier spacing used in the terminal of base station service When, it (can be a kind of or many that other above-mentioned terminals can be use other subcarrier spacings less than the first subcarrier spacing Kind) multiple terminals；And be only little than the first subcarrier spacing used in the terminal of base station service in the second subcarrier spacing A subcarrier spacing when, other above-mentioned terminals are the one or more terminals using the second subcarrier spacing.

In any of the above-described technical scheme, it is preferable that described resource allocation method also includes：Carried according to the described first son Ratio between wave spacing and second subcarrier spacing, determines and is indicating to be divided in the Resource Block to any terminal DCI (Downlink Control Information, the descending control for being used during the part resource that other terminals of dispensing are used Information) signaling bit number.

In the technical scheme, due to there is multiple proportion between subcarrier spacing, therefore can be according to the first son Ratio (i.e. multiple proportion) between carrier wave interval and the second subcarrier spacing carrys out true directional terminals and indicates to be allocated in Resource Block The bit number of the DCI signaling for being used during the part resource for using to other terminals.For example, if the first subcarrier spacing and second Ratio between subcarrier spacing is 2, then the bit number of the DCI signaling is that 2, i.e., each bit is corresponded in two pieces of resources of instruction Whether one of resource is taken by other terminals.

In any of the above-described technical scheme, it is preferable that notify other terminals of base station service to any terminal The step of the second subcarrier spacing for using, specifically include：

The numerical value of second subcarrier spacing is notified to any terminal；Or

The ratio between first subcarrier spacing and second subcarrier spacing is notified to any terminal.

In any of the above-described technical scheme, it is preferable that to the scheme of all terminal distribution communication resources of base station service, main The following two kinds to be had：

Allocative decision one：

The corresponding Resource Block granularity of minimum subcarrier spacing according to used in all terminals of base station service, to institute State all terminal distribution communication resources.

Allocative decision two：

The corresponding Resource Block granularity of the subcarrier spacing that used according to each terminal in all terminals, to described per The individual terminal distribution communication resource.

Further, specifically also included to each terminal distribution communication resource in the case of by allocative decision two：

According to the subcarrier spacing for being used order from big to small, successively to each terminal distribution communication resource described, Wherein, for the terminal using larger subcarrier spacing, the part resource in the Resource Block which distributes allows to be assigned to Other terminals using less subcarrier spacing；Or

According to the subcarrier spacing for being used order from big to small, successively to each terminal distribution communication resource described, Wherein, for the terminal using larger subcarrier spacing, the part resource in the Resource Block which distributes does not allow to be divided again Dispensing is using other terminals of less subcarrier spacing；Or

According to the subcarrier spacing for being used order from small to large, successively to each terminal distribution communication resource described, Wherein, presence is not allowed to be already allocated to using less in the Resource Block of the terminal distribution using larger subcarrier spacing The part resource of other terminals of subcarrier spacing.

Further, by allocative decision two come to each terminal distribution communication resource in the case of, can pass through with Under type is reducing the bit number of above-mentioned DCI signaling：

Mode one：

Connect at least one terminal distribution of the subcarrier spacing used in all terminals less than or equal to first predetermined value Continuous Resource Block.

In mode one, if at least one to the subcarrier spacing less (i.e. less than or equal to first predetermined value) for using The Resource Block of terminal distribution is discontinuous, is such as in the Resource Block under larger subcarrier spacing to the resource of a certain terminal distribution Multiple discontinuous position, then to after this Resource Block of terminal distribution using the larger subcarrier spacing, just need To indicate in this Resource Block, to be assigned to the part of other terminals by more detailed indicating mode, and then can cause The more problem of the bit number of DCI signaling, therefore can be to using less subcarrier spacing (less than or equal to first predetermined value) Terminal as far as possible distribute continuous Resource Block.

Mode two：

Needing to distribute to the part resource in the Resource Block under arbitrary subcarrier spacing using another subcarrier spacing Terminal when, the ratio between arbitrary subcarrier spacing and another subcarrier spacing should be less than or equal to second pre- Definite value.

In mode two, if the ratio between two subcarrier spacings is bigger, illustrate that the two subcarrier spacings are each right The Resource Block granularity that answers also differs larger, and the ratio between such as subcarrier spacing 1 and subcarrier spacing 2 is 2, UE#1 using son Carrier wave is spaced 1, UE#2 and uses subcarrier spacing 2, then wherein in the Resource Block by UE#1 under subcarrier spacing 1 When dividing (two parts altogether) to distribute to UE#2, base station only needs which portion in the Resource Block to be indicated by the DCI signaling of 2bit to UE#1 Divide and taken by UE#2.And if the ratio between subcarrier spacing 1 and subcarrier spacing 3 uses subcarrier spacing 1 for 8, UE#1, UE#3 uses subcarrier spacing 3, then the part (eight part altogether) in the Resource Block by UE#1 under subcarrier spacing 1 When distributing to UE#3, base station need to be indicated to UE#1 by the DCI signaling of 8bit in eight parts of the Resource Block per part whether by UE#3 takes, and this is obviously the increase in the bit number of DCI signaling.Therefore if desired by the Resource Block under a certain subcarrier spacing Part resource distribute to terminal using another subcarrier spacing, then the ratio between the two subcarrier spacings should be tried one's best Little.

Mode three：

For resource allocation methods, the present invention proposes the following two kinds scheme：

Resource Allocation Formula one：The RB for being formed according to the minimum subcarrier spacing used in terminal is adjusted for granularity Degree.

Specifically, such as when the subcarrier spacing that terminal is used is f₀When, RB number is that 100, numbering is 0～99, these RB can be defined as RB, and (1, i), 1 expression subcarrier spacing therein is 1 times of f₀, i value as 0～99；When terminal is used Subcarrier spacing be 2f₀When, RB number is defined as RB for 50, these RB, and (2, j), therein 2 represent that subcarrier spacing is 2 times F₀, j value is 0～49；When the subcarrier spacing that terminal is used is 4f₀When, RB number for 25, these RB be defined as RB (4, J), 4 expression subcarrier spacing therein is 4 times of f₀, j value is 0～24；……

According to above-mentioned definition, RB (4,0) is RB (2,0) and RB (2,1) composition；RB (2,0) be RB (1,0) and RB (1,1) constitutes.

By taking three users as an example, and UE#1 uses subcarrier spacing f₀, UE#2 is using subcarrier spacing 2f₀, UE#3 is using son Carrier wave is spaced 4f₀If the RB for being formed according to the minimum subcarrier spacing used in terminal is scheduling for granularity, may be just like Allocation result shown in Fig. 8, specific as follows：

UE#1：RB (1,7), RB (1,8)；

UE#2：RB (1,6)；

UE#3：RB (1,9), RB (1,10), RB (1,11).

Resource Allocation Formula two：The RB that subcarrier spacing according to each terminal itself is formed is scheduling for granularity.

Specifically, the subcarrier spacing that such as UE#1 and UE#4 are used is f₀, then UE#1 and UE#4 is f₀Customer group；UE# The 2 and UE#5 subcarrier spacings for using are 2f₀, then UE#2 and UE#5 is 2f₀Customer group；UE#3 and UE#6 is using between subcarrier It is divided into 4f₀, then UE#3 and UE#6 is 4f₀Customer group.

It is the same to assume that above-mentioned UE obtains the priority of resource, that is to say, that these UE may have different time delays to want Ask, as long as but to determine that they can be scheduled for resource in this subframe according to delay requirement just permissible for base station.In addition, these UE exist It is also that clearly each UE needs to obtain much bandwidth in this subframe that this subframe needs the resource base station for obtaining much bandwidth It is all based on QoS (Quality of Service, service quality) and the data that has transmitted and the data waiting for transmission of each UE Amount etc. is determining.

On the basis of upper hypothesis, next resource allocation is carried out according to different groups, this is divided into multiple situations again：

Situation one：

First distributed with the user of subcarrier spacing maximum, and above allocated resource can distribute to use below Family.Order i.e. according to the subcarrier spacing for being used from big to small, distributes the communication resource to each user successively, wherein, right In the user using larger subcarrier spacing, the part resource in the Resource Block which distributes allows to be assigned to using less Subcarrier spacing other users.

By taking Fig. 8 as an example, the subcarrier spacing maximum that used due to UE#3, then UE#3 elder generation Resources allocation, if to UE#3 Be assigned with RB (4,2), backward UE#2 Resources allocation, if be assigned with RB (2,3) to UE#2, most backward UE#1 Resources allocation, As above allocated resource can distribute to user below, therefore can to UE#1 distribution RB (1,7) and RB (1,8), Also part resource that will be in RB (2,3) and RB (4,2) is allocated to UE#1.

Situation two：

First distributed with the user of subcarrier spacing maximum, and above allocated resource cannot distribute to use below Family.Order i.e. according to the subcarrier spacing for being used from big to small, distributes the communication resource to each user successively, wherein, right In the user using larger subcarrier spacing, the part resource in the Resource Block which distributes does not allow to be assigned to use again Other users of less subcarrier spacing.

As above allocated resource cannot distribute to user below, therefore this allocative decision is not in figure The situation of RB (1,7) and RB (1,8) is distributed in 8 to UE#1.

Situation three：

With subcarrier spacing minimum user first distribute, before allocated resource be probably big subcarrier spacing under RB Ingredient, user below can be distributed to.Order i.e. according to the subcarrier spacing for being used from small to large, successively to Each user's distribution communication resource, wherein, has allowed portion in the Resource Block of the user's distribution using larger subcarrier spacing Point resource is already allocated to other users using less subcarrier spacing.

By taking Fig. 8 as an example, the subcarrier spacing minimum that used due to UE#1, therefore first to UE#1 Resources allocation, if to UE# 1 is assigned with RB (1,7) and RB (1,8)；Backward UE#2 Resources allocation, as RB (1,7) is the part in RB (2,3), be Ensure maximally utilizing for resource, can by remaining resource allocation in RB (2,3) to UE#2；Similarly, dividing to UE#3 When joining resource, UE#3 can be distributed in the part not taken by UE#1 in RB (4,2).

Situation four：

With subcarrier spacing minimum user first distribute, before allocated resource be probably big subcarrier spacing under RB Ingredient, it is not possible to distribute to user below.Order i.e. according to the subcarrier spacing for being used from small to large, successively Distribute the communication resource to each user, wherein, do not allow in the Resource Block of the user's distribution using larger subcarrier spacing There is the part resource for being already allocated to other users using less subcarrier spacing.

As above allocated resource cannot distribute to user below, therefore this allocative decision is not in figure To UE#2 distribution RB (2,3) in 8, and the situation to UE#3 distribution RB (4,2).

2nd, the signaling indication method of resource：

For the resource allocation scene shown in Fig. 8, when base station is indicated to each user by DCI signaling, right It is easy to indicate in UE#1, directly indicates that RB (1,7) and RB (1,8) are the resource that distributes to which.But for UE#2, DCI signaling needs to indicate that RB (2,3) distributes to UE#2, simultaneously need to indicating that the RB (1,7) in RB (2,3) is not allocated to UE#2's.Need to indicate that RB (4,2) distributes to UE#3 similarly for UE#3, DCI signaling, simultaneously need to indicating in RB (4,2) RB (1,8) be not to UE#3.That is for the larger user of subcarrier spacing except indicate take which RB it Outward, in addition it is also necessary to indicate whether have by the part of other CUs in each RB.

In this regard, corresponding indicating means is：First passing through semi-static RRC signaling informs user when data are sent and received Subcarrier spacing value f1 for using, at the same inform minimum subcarrier spacing value f2 used in the user under the user base station or The ratio f1/f2 of user f1 and f2 is informed, is illustrated by taking ratio as an example below：

If 1 ratio is 1, need not additionally to indicate whether have in RB by the part of other CU, that is, it is used for referring to Show in the RB for distribute to user, which part is 0 by the DCI signaling of other CUs；

If 2 ratios are 2, to need the DCI signaling of 2bit, with inform in the RB for distribute to user be each half whether By other CU；

If 3 ratios are 4, the DCI signaling of 4bit to be needed, the RB is divided into 4 parts, which is informed in the user RB Individual part is by other CU.Wherein, be up to 14 kinds of the occupied situation of RB, the occupied situation of a portion has 4 Kind；The wherein occupied situation of two parts has 6 kinds；The occupied situation in wherein three parts has 4 kinds.If limited using compared with boy If the user at carrier wave interval as far as possible distributes continuous RB, the occupied situation of RB can be a little less, can be such as 9 kinds, i.e., its Middle a part of occupied situation has 4 kinds, and the occupied situation of two parts has 3 kinds, and the occupied situation in three parts has 2 kinds.

It is 3.75～480KHz in view of subcarrier spacing, so ratio maximum possible is 128, at this moment to need to indicate RB In which to be partly assigned to the bit number for needing during other users very many.In order to reduce bit number, base station is needed when RB is distributed Some principles are taken, such as：

1. distribute continuous RB as far as possible using the user of less subcarrier spacing；

If 2. a part will be extracted out in the RB using subcarrier spacing for f1 to give to the RB using subcarrier spacing for f2 During another user, it is ensured that the value of f1/f2 is as far as possible little；

If 3. having more part to be assigned to other users in the Resource Block under a certain big subcarrier spacing, then remaining Part should not just distribute to the user using big subcarrier spacing.

Additionally, another kind of indicating means as the present invention, it is also possible to inform that user is sending out by semi-static RRC signaling Subcarrier spacing value f1 for using when sending with receiving data, at the same inform used in the user under the user base station only than sub- load Little subcarrier spacing value f3 of wave spacing f1 or inform the ratio f1/f3 of user f1 and f3, indicating means afterwards with above-mentioned Similar.
