Resource distribution mode to PDSCH includes three kinds, and downlink resource distribution type 0 is bitmap (bitmap) mapping point Match, i.e., each scheduling resource units indicated whether to dispatch by 1 bit, scheduling resource units be resource block group (RBG, Resource Block Group), support discrete RB to dispatch.Downlink resource distribution type 1 is first with one or more ratios It refers in particular to show the RBG subset that UE is used, uses the mapping method of bitmap again in the subset of place, equally support discrete RB Scheduling.Downlink resource distribution type 2 is referred to by coding resource indicated value (RIV, Resource Indication Value) Show one section that distributes to UE continuous RB resource, wherein RIV is the combined coding of the initial position and length to distribution resource.

Resource allocation for uplink PUSCH includes two kinds of methods of salary distribution, and ascending resource distribution type 0 is continuous resource The method of salary distribution is identical as downlink resource distribution type 2.Ascending resource distribution type 1 supports discontinuous RB points of up to two clusters Match, comprising one or more continuous RBG in each cluster, and to the starting resource of two clusters index and ending resource index connection Compile in collaboration with code.

However, it is contemplated that newly eat dishes without rice or wine/characteristic of wireless (NR, New Radio), e.g., system bandwidth is big, business load dynamic Variation, a variety of subcarrier spacings etc. will lead to biggish expense if being multiplexed existing resource distribution mode, and, limit money The flexibility of source distribution.For example, the system bandwidth of a carrier wave is up to 400MHz, corresponding carrier number in existing NR Mesh may (correspondingly, 275) corresponding PRB number be at least for one of 3300 to 6600.For so big system Bandwidth can distribute the resource in whole system bandwidth according to resource distribution mode in similar LTE for UE.For this for UE The entire big wideband scenarios of distribution, if according to existing resource distribution mode, it will significantly increase signaling overheads.Another kind side Formula configures the fractional bandwidth in entire big broadband for UE, but its bandwidth is still much larger than in existing LTE as the system of UE configuration Bandwidth can equally have that significant signaling overheads increases.

For the above problem existing for the relevant technologies, at present it is not yet found that the solution of effect.

Resource distribution mode described in embodiment one will be described in further detail in embodiment below.

Embodiment two:

Present embodiment provides a kind of indicating mode of bandwidth.Present embodiment is mainly used for that embodiment is further described The indicating mode of correlation bandwidth in one.

The indicating mode of the bandwidth, including at least one of:

Mode one: bandwidth information is indicated by bitmap (bitmap) mode.

Specifically, indicate to distribute to the bandwidth information of terminal by a bitmap.Bitmap includes altogetherBit, the corresponding subband of each bit, highest order indicate that subband 0, lowest order indicate son Band N_bandwidth- 1, and so on.Optionally, the formula for calculating the bit number that bitmap includes can also be BW system band Width is substituted for corresponding RB number or RBG number or RE number, similarly, SubBW subband width is substituted for its corresponding RB number Or RBG number or RE number.If some subband is allocated to some terminal, corresponding bit is set to 1 in bitmap；Instead It, if some subband is not yet assigned to some terminal, corresponding bit is set to 0 in bitmap.

Mode two: bandwidth information is indicated by bandwidth mode field or domain.

Specifically, indicate to distribute to the bandwidth information of terminal by a bandwidth mode field or domain.The bandwidth mould Formula field or domain include n-bit altogether.Different bandwidth mode is indicated by difference bit position 0 or 1 corresponding in n-bit.Its In, n is the positive integer more than or equal to 1.

Optionally, n-bit can be used to indicate bandwidth mode entirely.Alternatively, being indicated whether using a bit in n-bit To occupy resource or bandwidth indicating mode.Preferably, this use the highest-order bit or lowest bit position indicate it is described whether for Occupy resource or bandwidth indicating mode.Remaining bit is used to indicate bandwidth mode.

For example, the bandwidth mode field or domain use 2 bits, at least one of situation can be indicated: without bandwidth mould Formula；Full bandwidth mode；Almost full bandwidth mode；Fracti onal bandwidth mode.Specific to use " 00 ", " 01 ", which refers in " 10 ", " 11 " Show that one of above-mentioned bandwidth mode is not intended to limit.

For another example, the bandwidth mode field or domain use 1 bit, and being used to indicate full bandwidth mode also is non-full bandwidth mould Formula.For another example, using 2 bits, the highest-order bit is used to indicate whether that, to occupy resource or bandwidth indicating mode, remaining 1 bit is used In instruction full bandwidth mode be also non-full bandwidth mode.

Without loss of generality, the mode can be used for the scene of other similarly problems, it is not limited to present embodiment Or heretofore described scene or mode.

By taking Fig. 3 as an example in the way of signal instruction bandwidth.Fig. 3 is that base station is that the bandwidth of terminal distribution is shown in the embodiment of the present invention It is intended to.Base station bandwidth mode field in specific signaling is designated as the bandwidth information of terminal distribution.Specially the signaling or first Signaling can be high-rise wireless resource management RRC signaling, alternatively, physical layer descending controls information DCI signaling.The DCI signaling It can make the DCI signaling that uplink is proprietary, or, the DCI signaling that downlink is proprietary, alternatively, shared DCI signaling.

Mode three: bandwidth information is indicated by bandwidth indication field or domain.

Specifically, indicate to distribute to the bandwidth information of terminal by a bandwidth indication field or domain.The bandwidth word Section or domain can be indicated using m bit.Wherein, m is the positive integer more than or equal to 1.

Optionally, m bit can be used to indicate bandwidth information entirely.Alternatively, being indicated whether using a bit in m bit To occupy resource or bandwidth indicating mode.Preferably, this use the highest-order bit or lowest bit position indicate it is described whether for Occupy resource or bandwidth instruction.Remaining bit is used to indicate bandwidth information.For example, m is set to the vacant resource of 1 expression when m is 1 Bandwidth, conversely, m is that 0 expression occupies resource bandwidth.For another example, when m is 1, m is set to 1 expression and indicates non-full bandwidth, or, part band Wide situation.Conversely, m is set to 0 expression instruction full bandwidth situation.

For another example, when m is 2, the highest-order bit sets 0 expression full bandwidth mode, and the highest-order bit sets the non-full bandwidth side of 1 expression Formula.Lowest bit position is that 0 expression occupies resource instruction, and lowest bit position indicates vacant resource situation for 1.In the present invention Unoccupied resource is actually to occupy the supplementary set of resource.

Optionally, it may be incorporated into whether one indicate to occupy resource, and/or, the field of occupied bandwidth or domain occupy X Bit.X is the positive integer more than or equal to 1.For example, whether a bit indication indicates to occupy resource, and/or, occupied bandwidth Information.If what is indicated is occupancy resource, and/or, the information of occupied bandwidth, corresponding bit is set to 0.Conversely, if instruction It is vacant resource, and/or, the information of vacant bandwidth, corresponding bit is set to 1.

Optionally, whether the resource for being used to indicate whether currently to indicate or bandwidth are the resource occupied or bandwidth letter Breath, also the information consolidation with the distribution of instruction respective resources or bandwidth instruction indicates.

Which is merely illustrative of described in present embodiment, it is not limited to setting or value in the citing or Form of presentation.

In addition, the above-mentioned field for being used to indicate bandwidth information or bitmap information, carry at least one of signaling: High-rise wireless resource management RRC signaling, alternatively, physical layer descending controls information DCI signaling, alternatively, MAC signaling.The DCI The DCI signaling that signaling can make uplink proprietary, or, the DCI signaling that downlink is proprietary, alternatively, shared DCI signaling.

Embodiment three:

Present embodiment provides a kind of indicating mode of resource allocation.Present embodiment is mainly used for that implementation is further described The indicating mode of related resource distribution in mode one.

Herein, base station is using whole system bandwidth as reference to the resource of terminal distribution.Only with frequency in present embodiment It for the resource distribution mode of domain, but is not only limited to for which to be used for frequency domain, time domain is equally applicable.For example, frequency domain reference object It is adjusted to time domain reference object, e.g., subframe, time slot, time window, radio frames, symbol, above-mentioned any combination etc..

The indicating mode of the resource allocation, including at least one of:

Mode one: in the way of bitmap (bitmap), resource allocation information is indicated.

The bitmap (bitmap) can indicate following situations: situation one, and instruction is distributed to equipment (base station or terminal) and accounted for Resource；Equipment (base station or terminal) unappropriated resource is distributed in situation two, instruction.

For mode one, it is to occupy resource situation that either bitmap instruction, which occupies resource still, in big bandwidth In scene, if the corresponding relationship of existing bandwidth and RBG size can not using RBG as the smallest resource allocation granularity Meet demand.On the other hand, this mode also can not distribute resource according to single RB.This will make for small business load When situation, if still carrying out resource allocation in this manner, it is likely to result in the biggish wasting of resources.However, if according to RB The minimum particle size of resource allocation is carried out, then will appear signaling or the larger problem of overhead bit again.

It in order to reduce overhead bit, can handle as follows: the corresponding pass between modification RBG size and bandwidth System.

In existing LTE, corresponding relationship between system bandwidth and RBG Size, as shown in table 1.Note: subcarrier spacing 15KHz。

Table 1

However, supporting different subcarrier spacings, and indicated with 15KHz*2n in NR.N is more than or equal to 0 Positive integer.For example, 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz etc..Further, it is needed support in NR Bandwidth be at least 100MHz, it is maximum up to 400MHz, even more greatly.In such case, if the subcarrier spacing that equipment uses Still be 15KHz, then under the minimum bandwidth 100KHz of support, corresponding PRB number is 500, the PRB of existing LTE with RBG Size corresponding relationship is to be unable to meet demand.At this moment need to define the relationship of new bandwidth and RBG Size., whereas if Equipment uses bigger subcarrier spacing, then the corresponding relationship in above-mentioned table 1 between bandwidth and RBG Size still can be used.So And when the corresponding PRB number in the specific subcarrier interval of configuration is unsatisfactory for the case where providing in table 1, for example, shown in table 2, Therefore, it is necessary to define new corresponding relationship, to adapt to the case where PRB number is greater than PRB described in existing table.

Table 2

The definition of corresponding relationship between new bandwidth and RBG, it may be considered that once several aspects: aspect one: do not increase Bitmap indicates the bit for including.Aspect two: consider increasing to compromise between overhead bit and resource allocation granularity.

Table 3

Table 3 is in the case where keeping existing bitmap to include bit, the definition of RBG Size, and it is former that table 3 is only given at holding Have the bitmap of instruction resource allocation occupy the constant situation of bit case (for example, maximum 20M bandwidth, corresponding RBG is 4, 25) bit that bitmap is occupied is up to, provide corresponding RBG Size under some typical bandwidth.Other bandwidth are corresponding RBG Size situation is just no longer enumerated one by one here, and method is similar.It can see from table 3, in this manner it is achieved that a RBG In include RB number it is more, this mode is unfavorable for giving duty factor lesser terminal distribution resource, if in this manner Carry out resource allocation, it will cause certain problem of resource waste.

Based on this, another way is the bit number that increase bitmap appropriate includes, to include in the RBG that compromises The big situation of RB number.It is 15KHz in subcarrier spacing for example, for 100MHz situation, corresponding RBG size can be with It is 50 for the corresponding bit of 10, bitmap.Calculating the formula of bit that bitmap is occupied isIt can With by subcarrier spacing, and, the bit number that bitmap includes, and, RB number of occupancy, on RBG size is mutually determining State one of parameter.

Mode two: using the resource of RIV instruction distribution.Coding resource indicated value (RIV, the Resource Indication Value) it is used to refer to show distribute to UE one section of continuous resource, wherein RIV is risen to distribution resource The combined coding of beginning position and length.

With existing LTE difference, heretofore described RIV is other than the resource of terminal UE is distributed in instruction, also It can serve to indicate that the resource for being not yet assigned to UE.The unappropriated resource is that the UE cannot be occupied.The UE is matched by base station The unappropriated resource set can determine the case where own resource distribution.

The instruction of the resource allocation is comprised in DCI format X signaling.DCI format X can be 1A/ 1B/1D/1C/0A/0B/4A/4B.For ascending resource distribution, DCI format 0A/0B, resource allocation is to pass through What " Resource block assignment and hopping resource allocation " field was specified.For DCI Format 4A/4B, resource allocation are specified by " Resource block assignment " field.In order to tell end The resource of end distribution is the resource that itself is occupied, and still, the resource (i.e. unappropriated resource) that itself cannot be occupied is needed upper State the content for increasing instruction Resource Properties in DCI format format.The Resource Properties are exactly to be used to illustrate to indicate in the DCI Resource be that oneself can be occupied or can not occupy.The specific mode for increasing Resource Properties, including at least one of:

Method one: increasing an occupancy resource/vacant resource identification field in DCI format, is characterized with t bit. The DCI format can be the format format of instruction resource allocation in existing LTE technology, and, other new definition Format.T is the positive integer more than or equal to 1.

For example, for PDSCH, the content in DCI format 1A/1B/1D/1C for characterizing resource allocation may include One of instruction below:

Centralization/virtual reality B assignment mark, accounts for 1 bit.

Resource block assignment field, wherein centralized VRB is occupiedBit；It is distributed VRB is indicated according to the bit indicated in existing LTE.

Resource/vacant resource identification field is occupied, with t bit.For example, the field is set to 0 expression with 1 bit identification Resource is occupied, which is set to the vacant resource of 1 expression.If in DCI format not including the field, then it represents that the money of instruction Source is assigned as the resource for needing to occupy.

For PUSCH, similarly, just no longer repeated explanation one by one here.

Method two: using being used to indicate in existing DCI format format, centralization/distributed bit is implicit to know finger Show the attribute of resource.It is flexible that this mode may limit instruction occupancy resource/vacant resource mode to a certain extent Property.

For example, the bit is set to 0, then it represents that instruction is occupancy resource (or, vacant resource), and/or, centralization VRB distribution.Conversely, the bit position 1, then it represents that instruction is vacant resource (or, occupying resource), and/or, it is distributed VRB distribution.

Method three: for indicating resource block assignment field, increase t additional bit.The increased bit can To be located at highest order, or, lowest order.The meaning of other bits characterization remains unchanged.T is the positive integer more than or equal to 1.

For example, former resource block assignment field, is indicated with 5 bits.In order to indicate Current resource be instruction be to account for With resource or vacant resource situation, then 1 bit is introduced, it is preferable that the added bits are placed on highest order, the highest Position is not used to calculate RIV value.After the calculating of the RIV value needs to remove newly-increased most significant bit, by the binary system Bits switch is decimal system RIV value, and then obtains the initial position of the resource, and, length.

Mode three: it is suitable for indicating discrete resource allocation.PDSCH is sayed, in resource allocation TYPE1, is passed through DCI format 1/2/2A/2B/2C or extended formatting indicate to distribute to the VRB of UE by d domain.Under big bandwidth scenarios, Continue to continue to use and existing resource situation is indicated for bitmap mode in type1 mode, it will causes great overhead bit.

Based on this, the case where vacant resource of the equipment can be indicated using other modes, to reduce overhead bit.This In the other modes be mode other than bitmap.The vacant resource situation of instruction is to occupy number of resources Mesh it is (remote) be greater than vacant resource the case where.

In type1, the mode of resource allocation is specific as follows, including at least one of:

First domain includesBit, for specifying selected RBG or REG or subband group subset, the i.e. value of p.P For RBG or REG or the size of subband group.

Whether the second domain includes 1 bit, deviate for the resource in specified subset.Alternatively, the second domain includes 2 bits, newly 1 bit introduced, for specifying whether resource is to occupy resource.2 bit can combine instruction subset bias internal and be No resource is to occupy resource, can also be with each bit is used to indicate respectively subset bias internal and whether resource is occupancy resource.

Third domain includes mark r.The r indicates the starting and end position index of k resource collection.K can be big In or equal to 2 positive integer.The resource can be RBG or REG or subband group.Corresponding each resource collection is one section continuous Resource.Wherein, N is RB/RBG or RE/REG or subband/subband group number；M is all set correspondence Starting point and end position number.

It is new to introduce a domain (occupying t bit), for specifying whether resource is to occupy resource.

If carrying in the DCI that terminal receives, instruction occupies resource or vacant resource information, the resource allocation refer to Show the corresponding instruction of field is exactly the resource occupied or unappropriated resource.

PUSCH is sayed, in resource classification type1, DCI format0A/0B/4A/4B or other format formats In newly introduce instruction and occupy resource/vacant resource indication field, occupy t bit, t is just whole more than or equal to 1 Number.Wherein, it is to occupy resource or the corresponding r value of vacant resource that the r value of resource allocation assignment instruction is then corresponding. The starting and ending location information of resource can be known based on the r value terminal.It is especially low, if the occupancy resource/vacant Resource indication field instruction is vacant resource, then the vacant resource information indirect gain that terminal needs to indicate by r is certainly Body occupies the case where resource.It is described to occupy the supplementary set that resource is vacant resource.

Embodiment four:

Present embodiment provides the specific implementation of an above embodiment.Here, one section of continuous resource point is provided The indicating mode matched.

Fig. 4 is the schematic diagram of one section of continuous resource distribution in embodiment of the present invention.The grey area Fig. 4 is base station to eventually The occupied bandwidth of distribution is held, grey grid spaces are the continuous resource distributed under the occupied bandwidth that base station is terminal configuration.

As shown in figure 4, the ratio that the bandwidth that base station is terminal distribution occupies in whole system bandwidth is bigger.In order to drop The low terminal that is indicated to directly indicates the information of occupied bandwidth, and causes overhead bit, then base station is that terminal indicates what it was not take up Bandwidth information, to obtain its occupied bandwidth information indirectly.

Further, if being currently indicated to the bandwidth of terminal is occupied bandwidth, still, vacant bandwidth.And/or such as The resource of what instruction bandwidth.Can by carried in signaling (physical layer DCI signaling, or, high-rise RRC signaling) with down toward One of few content:

Occupied bandwidth/vacant bandwidth field occupies t1 bit；For example, t1 occupies 1 bit, 0 indicates to occupy resource (example Such as, bandwidth) situation, 1 indicates vacant resource (for example, bandwidth).

Bandwidth resource allocation field occupies t2 bit；Wherein, the bit number that t2 is occupied, is continuous according to bandwidth resources Resource, still, discrete resource mode is related.And for continuous bandwidth, or, the indicating mode of discontinuous bandwidth resources It is detailed in embodiment three to continuous resource, and, corresponding content in discontinuous resource allocation.For example, as shown in connection with fig. 4, giving Terminal indicates unappropriated bandwidth, by encoding starting resource location index X1 and length L, obtains a RIV value, T2 bit of the field corresponds to the binary system that the corresponding decimal number of RIV is converted into.Discontinuous resource allocation, mode are similar The mode of resource is characterized in type1.

Subcarrier spacing indication field occupies t3 bit；For example, existing subcarrier spacing has: 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, etc..It, then can same bitmap in order to indicate the subcarrier spacing of distribution resource use Mode indicates, to the subcarrier that terminal configures, or, t easet ofasubcarriers.For example, 110000 be expressed as terminal configuration 15KHz and 30KHz.If reducing overhead bit, subcarrier spacing can be indicated with 3 bits, for example, 000 indicates 15KHz, 001 table Show 30KHz, 010 indicates 60KHz, and 011 indicates 120KHz, and 100 indicate 240KHz, and 101 indicate 480KHz.

By above-mentioned bandwidth field, terminal can know indirectly occupied bandwidth location information (for example, by system bandwidth, Vacant bandwidth, occupied bandwidth are the supplementary set of vacant bandwidth in system bandwidth).Further, in conjunction with Fig. 4, terminal can be with According to the resource distribution instruction signaling (for example, physical layer DCI signaling) under occupied bandwidth, obtains base station and really give terminal distribution Resource.It is specific as follows:

The first, the one section of continuous resource occupied directly to terminal configuration.At this point, instruction can not be carried in the signaling Occupy resource/vacant resources field.It is defaulted as occupying resource instruction.

Second, instruction terminal is not configured continuous, or, discrete resource.At this point, under the instruction occupied bandwidth In resource allocation contents, needs to carry instruction and occupy resource/vacant resources field.As described in Figure 4, base station can refer to for terminal Show vacant resource, for example, by the way that (starting point is X2 (being indicated in formula with S, such as s0), and end point is X3 (public according to set 1 Indicated in formula with S, such as s1)), (starting point is X4 (being indicated in formula with S, such as s2) to set 2, and end point is that X5 (uses S in formula Indicate, such as s3)) situation, utilize formulaAvailable r.Terminal according to the available resource not accounted for of r value, into One step, by occupied bandwidth, and, the resource situation not accounted for can obtain the resource location information of distribution indirectly.Wherein, N is RB/RBG or RE/REG or subband/subband group number；M is the number of all set corresponding starting point and end position.

Further, the resource for indicating distribution, it's similar to distribute in the existing resource method of salary distribution continuous resource Indicating mode.Optionally, for the subcarrier spacing except non-15KHz, need to provide an instruction subcarrier spacing field.

Above-mentioned bandwidth is indicated, and, the resource distribution instruction under bandwidth can be carried in a signaling, or, It can be carried and be indicated in different signalings respectively.The difference signaling can be physical layer DCI signaling, or, high level RRC believes It enables.

When another situation, if base station is smaller for the bandwidth of terminal distribution, at this point, being indicated to what terminal configuration occupied Resource.And further to the resource situation of terminal instruction distribution in the bandwidth of occupancy.At this point, according to terminal money is distributed to The occupancy situation in source, selection still, are indicated according to unoccupied resource mode using resource mode is occupied.For example, existing for terminal The little situation of the number of resources distributed on occupied bandwidth (for example, occupying resource is much smaller than vacant resource), it is preferable that use Occupy resource mode distribution.Conversely, similarly.Its mode of operation is same as above.

In addition, another situation, the case where for resource discrete for terminal distribution, can also using the application or The mode of embodiment is handled.Here, explanation will be no longer enumerated one by one.

Embodiment five:

Present embodiment provides a kind of resource distribution instruction mode of the numerology subband situation of all scheduling.It is described Terminal occupies whole bandwidth, and, different numerology is used on different sub-band.

Fig. 5 is the resource allocation schematic diagram that different sub-band uses different numerology in embodiment of the present invention.Such as Fig. 5 Shown, it is the corresponding sub- bandwidth resources of f1 that grey, which is tiltedly marked as subcarrier spacing, and Dark grey grid is that subcarrier spacing is f2 pairs The sub- bandwidth resources answered, dark-grey nicking are that subcarrier spacing is the corresponding sub- bandwidth resources of f3.During the multiple subband is wide extremely It is one of few to be allocated to a terminal.That is, a terminal can configure multiple subbands, and, different sub-band configures not Same subcarrier spacing can also share whole bandwidth with multiple terminals, and, different terminals occupy different sub-band, and use each other Subcarrier spacing it is different.

It is assumed that the whole bandwidth distributes to a terminal entirely, and, terminal configures different subcarriers on different bandwidths Interval.In order to indicate resource allocation conditions on different bandwidths, the resource distribution instruction mode provided in the present invention to terminal It is still applicable in such a scenario.Concrete mode is as follows:

It assumes base stations as terminal 1 and distributes subcarrier f1 corresponding to resource in bandwidth.Its mode for distributing resource, including it is following At least one:

Base station is that terminal 1 indicates that f1 subcarrier corresponds to the bandwidth information other than bandwidth.Indicating mode includes: method one, is referred to Show the corresponding bandwidth aggregation of f2 and f3.Optionally, the corresponding subcarrier spacing instruction of f2 and f3 can be carried in the bandwidth aggregation. Method two indicates respectively that subcarrier spacing f1 and f2 correspond to bandwidth.It, can also in the corresponding bandwidth signalling of the instruction f2 and f3 Indicate that f2 and f3 corresponds to the resource distribution instruction information in bandwidth (for example, the money occupied in corresponding bandwidth can be indicated to carry Source instruction, or, unappropriated resource indicates).And for mode one, then it needs further to indicate that f2 and f3 are corresponded in bandwidth Resource allocation.The instruction information can be the same signaling with the signaling of instruction bandwidth, alternatively, different signaling instructions.In addition, Terminal 1 is indicated according to the vacant bandwidth of instruction, the bandwidth information that base station is oneself distribution is obtained, further, same Signaling, or, obtaining resource distribution instruction in the corresponding bandwidth of the f1 by another signaling received.Here resource What distribution can indicate is the resource occupied, or, instruction is unappropriated resource.This mode, evaded respectively f1, f2 and The bandwidth of f3, and, big overhead bit caused by corresponding resource distribution instruction under respective bandwidth.

It is assumed that the whole bandwidth distributes to multiple terminals (for example, 3 terminals, f1 counterpart terminal 1, f2 counterpart terminal entirely 2, f3 counterpart terminals 3), and, terminal configures different subcarrier spacings on different bandwidths.In order to indicate to terminal in different band Resource allocation conditions on width, the resource distribution instruction mode that provides still is applicable in such a scenario in the present invention.

If in the first signaling that terminal receives, the occupancy resource (or bandwidth)/vacant resource (or bandwidth) word Section instruction is vacant resource (or bandwidth).Then terminal can obtain vacant bandwidth or resource according to the bandwidth indication field Corresponding location information.

Further, the resource allocation field indicated according to the first signaling or the second signaling, and/or, under nominated bandwidth It occupies resource/vacant resources field and knows that the location information of the resource allocation is the resource oneself to be occupied, still, no The resource that can not occupied ().Wherein, in the instruction bandwidth information, and/or, indicate the resource distribution location information under bandwidth The resource can be carried in signaling uses subcarrier spacing.

However, existing money can be used for UE2 and the UE3 resource allocation on the corresponding frequency band of f2 and f3 respectively The source method of salary distribution e.g. indicates the resource information of the occupancy under corresponding bandwidth.

The bit of the occupancy, and/or, the mode of resource instruction, and, the resource allocation type of use can join Examine the scheme in embodiment one to four.

Embodiment six:

The present embodiment is mainly used for some cases except supplementary explanation above-described embodiment.

Base station is user device configuration bandwidth mode, and the bandwidth mode instruction is the bandwidth resources occupied, still, not The bandwidth resources of occupancy or the supplementary set resource of occupied bandwidth resource, except through predefined, physical layer upstream or downstream DCI letter It enables, bandwidth correlation specific field described at least one of high-rise RRC signaling, e.g., occupied bandwidth/vacant bandwidth field, or, It is used to indicate in the field of bandwidth resources and introduces except the modes such as m bit indication occupied bandwidth/vacant bandwidth, can also pass through Specific DCI format mode come to imply know instruction be vacant bandwidth, and/or, resources mode.For example, the DCI When one of format 1A/1B/1D/1C/0A/0B/4A/4B is used to indicate bandwidth and/or resource allocation conditions, user equipment By detect above-mentioned format format can know the resource currently indicated and/or, bandwidth is vacant bandwidth and/or money Source, or, occupied bandwidth and/or resource.Other DCI format formats for being used to indicate resource allocation are equally applicable described Method.Optionally, it does not carry in the DCI signaling or does not indicate occupied bandwidth and/or resource/vacant bandwidth and/or money When source information, then default base station to user equipment indicate be occupied bandwidth and/or resource information.

Optionally, for same user equipment, identical resources pattern can be used on different subbands, For example, the configuration no matter all used on that subband occupies resources mode (that is, base station is to user on which subband Equipment instruction is all the information for occupying resource), alternatively, the vacant resources mode of configuration no matter all used on which subband (that is, on which subband base station to user equipment indicate be all vacant resource information (occupy resource supplementary set Resource information))；Alternatively, different resource distribution moulds can be used on different subbands for same user equipment Formula, for example, on the first subband or subband group, what base station was indicated to user equipment is to occupy the information of resource, and in the second son On band or subband group, base station to user equipment indicate be vacant resource the information resource information of resource supplementary set (occupancy). That is, base station flexibly (can be accounted for the resource distribution mode on the user device configuration subband on multiple subbands With resource allocation or vacant resource allocation).

Optionally, it further expands to, user equipment is determined according to the predefined jump rule on multiple subbands Subband.Further, two sons before and after jump take, and base station can specify identical resource allocation side to user equipment Formula, or, different resource distribution modes (i.e. occupancy resource allocation or vacant resource allocation).The predefined jump Rule, for example, successively become larger or become smaller according to subband number, alternatively, according to jump granularity be M/ subband or RBG or REG or The interval RB or RE is jumped, alternatively, determining the subband jumped every time (for example, random between [1, d] according to random number way A positive integer is generated, so that it is determined that subband, d is the sum or the corresponding total RB/RBG/RE/REG number of subband of subband), Or, other modes.

Optionally, for different user equipmenies, identical resource distribution can be used on the same subband Mode.For example, the first user or user group are using occupancy resources mode or vacant resources mode, second user or user group Using occupancy resources mode or vacant resources mode.I.e. described occupancy resources mode/vacant resources mode is in user It is shared between equipment, rather than user equipment is proprietary；Alternatively, for different user equipmenies, in the same subband On can use different resources patterns.For example, the first user or user group are using occupancy resources mode or vacant Resources mode, second user or user group are also using the vacant resources mode of vacant resources mode.Set without user It can be the resource occupied according to respective resource allocation conditions, the resource of flexible configuration instruction between standby, it is still, vacant Resource, to reduce signaling overheads.

Optionally, the instruction band width configuration signaling, can be with the signaling for the resource allocation being used to indicate under the bandwidth For same signaling, it is also possible to independent signaling.For the latter, base station can be with actual schedule and/or the dynamic change of business, spirit The case where being user device configuration or indicating resource allocation living.

Optionally, for can equally use same band and/or resource allocation mode/mode between different community；Or Person, different bandwidth and/or resource allocation mode/mode.Similarly, it for the different UE in same cell, can equally use Same band and/or resource allocation mode/mode；Alternatively, different bandwidth and/or resource allocation mode/mode.
