Description

Resource allocation method and device for allocating resources

Technical field

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

Background technology

Existing 4G and 4.5G mobile communication technology, (Long Term Evolution, drills 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 support bigger bandwidth, 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 accesses) unauthorized carrier wave uses.Regardless of frame structure, All comprise 10 subframes, each subframe is 1ms, each subframe comprises two slot (time slot), a slot is 0.5ms, each Slot comprises 7 symbol (symbol) again.Frequency domain aspect, 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 a kind of subcarrier spacing of new 3.75kHz proposed 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 for 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.Also multiplexing is occurred in that in the same frame structure in the use of LAA unauthorized carrier wave DwPTS, as the descending scheduling time domain granularity of partial subframe, also using the scheduling granularity of the whole subframe of 1ms simultaneously. And in FDD frame structure and tdd frame structure, except the existing down sending time of the special subframe in tdd frame structure and up Send outside the time, or other subframe is all up transmission or descending transmission time domain separates frequency domain separately.

It can be seen that, the granularity of current frame structure and frequency domain resource all can make resource allocation underaction, and uplink scheduling The time of mechanism and HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) feedback mechanism etc. Interval makes time delay larger again, 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 is 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 and more of smaller particle size 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 business variation so that fix at present frame structure, fixing frequency domain resource granularity 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 There to be different subcarrier spacings.If specifically 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 uses Be f₀, and only need to use f₀When RB0, and at this time there is no 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 The need of distributing to UE#2, and how this designs which part of signaled UE#2 is used by other when distributing to UE#2 It is all technical problem urgently to be resolved hurrily that family employs.

Similar to there is frequency domain instruction, there is also the problem of time domain instruction, as shown in Fig. 2 such as using simultaneously The business corresponding scheduling slot length of different subcarrier spacings is different.Following situation in so corresponding time domain：UE# 1 uses subcarrier spacing f0 to be 15kHz, and so corresponding 1ms subframe comprises 2 slot, and each slot is 7 symbols.UE# 2 use subcarrier spacing 2f0 to be 30kHz, and so corresponding 1ms subframe comprises 4 slot, and each slot is 7 symbols.Its Domain scheduling minimum unit when middle Slot is.It would be possible that produced problem is exactly UE#1 having been allocated for the slot 0 of itself, but Be that UE#2 also has service needed to transmit below, and the priority of UE#2 be higher, at this moment for some RB UE#1 slot0 Latter half has just given UE#2.In this case, how to inform that UE#1 is the problem needing to solve.This problem is likely to out UE#1 and UE#2 uses same subcarrier spacing now, but when domain scheduling fineness ratio UE#1 of UE#2 is less, such as UE#2 Mini-slot using 2 symbols.Therefore, equally how to design which part of signaled UE#2 is used by other users It is also technical problem urgently to be resolved hurrily.

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 is so that base When standing in the multiple terminal distribution resource being spaced using different sub carrier, ensure that maximally utilizing of resource, and energy 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 device for allocating resources, including：Notification unit, uses In notify base station service any terminal used when communicating first when domain scheduling granularity, and described base station service All terminals in there is domain scheduling granularity when second in the case of, notify domain scheduling grain when described second to described any terminal Degree；Allocation unit, for all terminal distribution communication resources servicing to described base station；Indicating member, in described distribution When the part resource of the Resource Block under the subcarrier spacing that described any terminal is used by unit distributes to other terminals use, to Described any terminal sends DCI resource allocation information.

In this technical scheme, domain scheduling granularity and domain scheduling grain when second when having first in the terminal of base station service In the case of degree, by any terminal use first when domain scheduling granularity Resource Block in part resource distribute to other-end Use, notify the such resource allocation information of terminal so that the terminal of occupied resource knows which resource is occupied simultaneously.Logical Cross such technical scheme, so that terminal can accurately know itself allocated communication resource, pass through in order to terminal The allocated communication resource is receiving or to send data.

Domain scheduling granularity when domain scheduling granularity is less than described first in technique scheme it is preferable that when second, its In, domain scheduling granularity when domain scheduling granularity is minimum used in the terminal that described base station services when second, or when described second Domain scheduling granularity be the service of described base station terminal used in only than described first when the little when domain scheduling grain of domain scheduling granularity Degree.

In this technical scheme, when second domain scheduling granularity be base station service terminal used between minimum subcarrier Every when, above-mentioned other terminals can be using than first when domain scheduling granularity little other when domain scheduling granularity (can be one Kind or multiple) multiple terminals；And domain scheduling granularity is only than the first time domain used in the terminal that base station services when second During scheduling granularity little one during domain scheduling granularity, above-mentioned other terminals are or many using domain scheduling granularity when second Individual terminal.

In this technical scheme, due to when domain scheduling granularity between there is magnitude relationship, therefore can be according to first When domain scheduling granularity carry out true directional terminals with domain scheduling granularity when second and indicate in Resource Block, to be assigned to what other terminals used The bit number of the DCI signaling being used during part resource.Such as, if when first domain scheduling granularity and domain scheduling granularity when second it Between ratio be 2, and time between domain scheduling granularity when multiple second on not overlapping, then the bit number of this DCI signaling be 2, that is, Whether the one of resource in each bit two pieces of resources of corresponding instruction is taken by other terminals.But if multiple second time domains Can be overlapping on time between scheduling granularity, when such as first, domain scheduling granularity is 14 symbols, and when second, domain scheduling granularity is 7 Individual symbol, then domain scheduling granularity when can have 7 second in domain scheduling granularity when one first, such as first the second time domain Scheduling granularity comprises symbol 0～6, and second comprises symbol 1～7 ..., and the 7th comprises symbol 7～13.So this situation Under be accomplished by more bit numbers to indicate 7 time resource block positions.

In any of the above-described technical scheme it is preferable that notification unit specifically for：By semi-static RRC signaling to institute State any terminal and notify when described second domain scheduling granularity and domain scheduling grain when described second when domain scheduling granularity or described first Magnitude relationship between degree.

In any of the above-described technical scheme, (Radio Resource Control wireless provides it is preferable that semi-static RRC Source controls) transmission time of signaling is different from the transmission time notifying the RRC signaling of domain scheduling granularity when first.

In this scenario, such as certain section call duration time does not use domain scheduling granularity little when domain scheduling granularity during than first User, then only notify user itself use first when domain scheduling granularity；Next and if had for a period of time using ratio the A period of time domain scheduling granularity little when domain scheduling granularity user, then to user notify other users use second when domain scheduling grain The information of degree.

In any of the above-described technical scheme it is preferable that notification unit specifically for：By dynamic DCI signaling to described When second described in one terminal notification domain scheduling granularity or when described first domain scheduling granularity and domain scheduling granularity when described second it Between magnitude relationship.

Specific embodiment

In order to be more clearly understood that the above objects, features and advantages of the present invention, below in conjunction with the accompanying drawings and specifically real Mode of applying is further described in detail to the present invention.It should be noted that in the case of not conflicting, the enforcement of the application Feature in example and embodiment can be mutually combined.

Elaborate a lot of details in the following description in order to fully understand the present invention, but, the present invention also may be used To be implemented different from other modes described here using other, therefore, protection scope of the present invention is not described below Specific embodiment restriction.

Fig. 3 shows the schematic flow sheet of resource allocation method according to first embodiment of the invention, and this resource is joined The executive agent putting method can be base station.

As shown in figure 3, resource allocation method according to first embodiment of the invention, comprise the following steps：

Step S302, notify base station service any terminal used when communicating first when domain scheduling granularity, with And in the case of the domain scheduling granularity when having second in all terminals of described base station service, notify institute to described any terminal State domain scheduling granularity when second；

Step S304, to all terminal distribution communication resources of described base station service；

Step S306, the part resource of the Resource Block under the subcarrier spacing using described any terminal distributes to it When its terminal uses, send DCI resource allocation information to described any terminal.

Preferably, second when domain scheduling granularity be less than first when domain scheduling granularity, wherein, when second, domain scheduling granularity is base Domain scheduling granularity during minimum used in the terminal of the service of standing, or when second, domain scheduling granularity is to use in the terminal that base station services Only than first when the little when domain scheduling granularity of domain scheduling granularity.

In this technical scheme, described second time domain can be notified to described any terminal by semi-static RRC signaling Scheduling granularity or domain scheduling granularity and the magnitude relationship between domain scheduling granularity when described second when described first.

In this technical scheme, the transmission time of semi-static RRC signaling is different from and notifies domain scheduling grain when described first The transmission time of the RRC signaling of degree.

In this technical scheme, time domain during its own transmitting and receiving data of user is informed by semi-static RRC signaling Scheduling granularity t1.Then in the different time, using another RRC letter different from the RRC signaling of domain scheduling granularity t1 when informing Order notify when domain scheduling granularity t2 or when domain scheduling granularity t1 with when domain scheduling granularity t2 ratio.Such as this period does not use Than when domain scheduling granularity t1 little when domain scheduling granularity user, then only notify user itself use when domain scheduling granularity t1； Next have for a period of time using than when domain scheduling granularity t1 little when domain scheduling granularity t2 user, then believed by another RRC Order come to notify to this user's other users used when domain scheduling granularity t2 information.

In such an embodiment, it is preferable being carried out to using described first time domain granularity with domain scheduling granularity when described first The described terminal of communication sends DCI resource allocation information, when having part resource by under this base station in described first time domain granularity When being taken using the other-end that described second time domain granularity is communicated, with described second time domain granularity again to using described The described terminal that first time domain granularity is communicated sends described DCI resource allocation information, to inform second described in described terminal When domain scheduling granularity in the resource that takies of the other-end that communicated using described second time domain granularity so that using The described terminal that described first time domain granularity is communicated knows itself actual allocated resource.

In this technical scheme, in the case that the resource of terminal is not taken by other-end, the first of using terminal Time domain granularity is communicated, and when the resource of terminal is taken by other-end, it is to take the second time domain grain of the terminal of resource Degree carries out communication and sends DCI resource allocation information, thus in this way it is possible to notify that terminal, using domain scheduling grain when second Spend which resource the other-end being communicated occupies.

In this technical scheme, if domain scheduling when having one or more possible second in domain scheduling granularity when first The DCI signaling of granularity sends position, the terminal of domain scheduling granularity when notifying arbitrarily to use first using RRC signaling, and monitoring is wherein One or more possible second when domain scheduling granularity DCI signaling send position.

In this embodiment, notify domain scheduling granularity when described second also by dynamic DCI signaling to described any terminal Or domain scheduling granularity and the magnitude relationship between domain scheduling granularity when described second when described first.For example, because may RRC letter Order have little time to notify user it is possible to when equally using DCI signaled user the value of domain scheduling granularity t2 or when domain scheduling Granularity t1 with when domain scheduling granularity t2 magnitude relationship.

Preferably, with domain scheduling granularity when described first to the described terminal being communicated using described first time domain granularity Send DCI resource allocation information, when have in described first time domain granularity part resource by this base station under using described second when When the other-end that domain granularity is communicated takies, in an ensuing first time domain granularity to using described first time domain grain When the described terminal that degree is communicated sends DCI resource allocation information, when comprising in one first time domain granularity with described second Domain granularity occupies the information of the running time-frequency resource of described terminal for unit, so that being led to using described first time domain granularity The described terminal of letter knows itself actual allocated resource in domain scheduling granularity when upper one first.

It is preferable that this resource allocation method also includes in technique scheme：According to domain scheduling granularity when described first With the value of domain scheduling granularity when described second, determine and be assigned to other eventually in the described any terminal described Resource Block of instruction The bit number of required DCI signaling instruction during the part resource that end uses.

In this technical scheme, due to when domain scheduling granularity between there is magnitude relationship, therefore can be according to first When domain scheduling granularity and domain scheduling granularity when second value to be assigned to other terminals in true directional terminals instruction Resource Block and make The bit number of the DCI signaling being used during part resource.Such as, if domain scheduling granularity and domain scheduling grain when second when first Ratio between degree is not overlapping on 2, and time between domain scheduling granularity when multiple second, then the bit number of this DCI signaling is 2, whether one of resource that is, each bit corresponds in two pieces of resources of instruction is taken by other terminals.But if multiple second When domain scheduling granularity between can be overlapping on the time, when such as first, domain scheduling granularity is 14 symbols, domain scheduling grain when second Degree is 7 symbols, then domain scheduling granularity when can have 7 second in domain scheduling granularity when one first, such as first When two, domain scheduling granularity comprises symbol 0～6, and second comprises symbol 1～7 ..., and the 7th comprises symbol 7～13.So this It is accomplished by more bit numbers to indicate 7 time resource block positions in the case of kind.

In technique scheme, comprise to occupy institute in units of described second time domain granularity in one first time domain granularity In the information of the running time-frequency resource stating terminal, also comprise the original position of time resource and time span and the frequency domain resource taking Position.
