Description

The equipment and the method for indication channel resource allocation in the wireless communication system

Technical field

The present invention relates to wireless communication system, particularly relate to the equipment and the method for indication channel resource allocation in the wireless communication system.

Background technology

At present, 3GPP standardization body has set about beginning its existing system standard is carried out long-term evolution (Long Term Evolution is hereinafter to be referred as LTE).OFDM (OrthogonalFrequency Division Multiplexing is designated hereinafter simply as OFDM) technology is with its higher availability of frequency spectrum, and lower processing complexity becomes the downlink transfer scheme that LTE adopts.

Be a kind of multi-carrier modulation communication technology on the OFDM technological essence, its basic principle is the data flow of a two-forty to be decomposed into several rate data streams transmit simultaneously on one group of mutually orthogonal subcarrier.The OFDM technology is because its multicarrier character has performance advantage aspect a lot.(1) significant advantage of OFDM technology is because data parallel transmission on a plurality of subcarriers respectively, and the corresponding growth of the length of the symbol on each subcarrier is insensitive to channel delay; Add protection on each symbol at interval by further giving, promptly introduce Cyclic Prefix (CP, Cyclic Prefix), under the situation of channel delay, can eliminate intersymbol interference (ISI) fully less than circulating prefix-length.Like this, each subcarrier has all experienced flat fading channel.(2) availability of frequency spectrum height of OFDM technology, ofdm signal are actual on frequency domain an overlapping, and this overlapping on improved the availability of frequency spectrum to a great extent.(3) ability of the anti-narrow band interference of OFDM technology and frequency selective fading is stronger.Can make OFDM obtain frequency diversity and time diversity gain by chnnel coding with interweaving, thereby resist narrow band interference and frequency selective fading effectively.(4) modulation of OFDM technology can realize by baseband I FFT conversion, and IFFT/FFT has ripe quick calculation method, can realize in dsp chip and hardware configuration easily.

The frame structure of the descending ofdm system of existing LTE as shown in Figure 1.Radio Resource is structure (101-103) with the frame, and frame length is identical with WCDMA, is 10ms; Each radio frames is subdivided into a plurality of subframes (104-107) (present hypothesis is that every frame comprises 20 subframes, and subframe is long to be 0.5ms); Each subframe comprises a plurality of OFDM symbols according to the difference of configuration, and short CP subframe comprises 7 symbols (108), and long CP subframe comprises 6 symbols (109).In the LTE system, need effectively to support unicast service and multicast/broadcast business simultaneously that most probable multiplex mode is a Time Division Multiplexing.Wherein the symbol of the OFDM of unicast service only needs relatively shorter Cyclic Prefix (CP, about 4.8 μ s).For multicast/broadcast business, consider to be not inclined in the LTE system to require system synchronization, and the influence of each sub-district propagation delay, the OFDM symbol of multicast/broadcast business must dispose long CP (about 16.7 μ s).Different just because of clean culture OFDM symbol with the CP length that multicast/broadcast OFDM symbol need dispose, caused the number of the OFDM symbol that can comprise in the corresponding subframe different (short 7 symbols of CP subframe, 6 symbols of long CP subframe).

The uplink scheme of LTE has adopted single-carrier frequency division multiple access access (hereinafter to be referred as SC-FDMA) technology.SC-FDMA is a kind of availability of frequency spectrum height, the wireless multiple access access technology that peak-to-average ratio is low, and the implementation of its frequency domain is as shown in Figure 5.Modulation symbol 501 carries out fast fourier transform (hereinafter to be referred as FFT) 502 modules earlier and transforms to frequency domain, shines upon 503 modules by subcarrier then and carries out concrete mapping.Data after the subcarrier mapping are carried out inverse fast fourier transform (hereinafter to be referred as IFFT) 504 modules and are transformed to time domain.Module 505 adds Cyclic Prefix (hereinafter to be referred as CP) before data.Add CP and mainly contain two effects: the one, eliminate because the asynchronous interference between the subcarrier that causes on the frequency domain of each subscriber equipment; The 2nd, the introducing of CP can make receiver serviceability height, frequency domain equalization algorithm that complexity is low.Because SC-FDMA uses the resource distribution mode of quadrature to eliminate the interference in the sub-district, owing to the raising of frequency domain equalization algorithm to performance, the availability of frequency spectrum of SC-FDMA is very high simultaneously.The another one characteristic of SC-FDMA is owing to introduced FFT module 502, and the peak-to-average ratio of signal is lower, thereby makes the efficient of power amplifier of subscriber equipment higher thereby reduced the complexity of power amplifier.Thereby being the user of cell edge, the another one benefit that peak-to-average ratio is low can use higher data speed to improve the covering of base station.In the research of LTE, as shown in Figure 6 to the hardwood structure of SC-FDMA design.Radio Resource is structure (601-603) with the frame, and frame length is 10ms; Each radio frames is subdivided into a plurality of subframes (604-607) (present hypothesis is that every frame comprises 20 subframes, and subframe is long to be 0.5ms); Each subframe comprises a plurality of SC-FDMA symbols, and wherein long symbol has 6 (608,610,611,612,613 and 615), and short symbol has 2 (609 and 614).Short symbol is commonly used to transmit pilot tone.

In current LTE discusses, the mode that has two kinds of basic channel resources to divide.First kind is local formula transmission channel, promptly some continuous subcarriers is divided into a channel as Resource Block, and this method helps utilizing multi-user diversity, thereby improves the throughput of system.Another kind is the distributed transmission channel, the running time-frequency resource of promptly distributing to some subscriber equipmenies be distributed to whole with certain rules or partial-band in, thereby the gain of frequency diversity is bigger.These two kinds of channel distribution modes respectively have superiority and replenish mutually, can be applied in the same subframe simultaneously, thereby in a subframe, use local formula transmission channel to obtain multi-user diversity gain, use the distributed transmission channel to obtain frequency diversity gain the other subscriber equipment to some subscriber equipmenies.

The scheduling of customer equipment data and transmission are to be base unit with the Resource Block.In current discussion, the notion of Physical Resource Block (Physical resourceblock) and virtual resource blocks (Virtual resource block) has been proposed about LTE down channel resources dividing mode.Physical Resource Block comprises M continuous sub-carriers on frequency domain, comprise N continuous OFDM symbol simultaneously in time.Virtual resource blocks is abstract to channel resource on Physical Resource Block, and virtual resource blocks is divided into distributed virtual resource block and local formula virtual resource blocks.Distributed virtual resource block is corresponding to the resource of distributed transmission channel, and local formula virtual resource blocks is corresponding to the resource of local formula transmission channel.

In current discussion, adopted the notion of Resource Unit (Resource unit) about LTE uplink channel resources dividing mode.Resource Unit is further divided into local formula Resource Unit (LocalizedRU) and distributed resource units (Distributed RU).Local formula Resource Unit comprises a continuous M subcarrier on frequency domain, comprise N SC-FDMA symbol simultaneously in time; Distributed resource units comprises the subcarrier that M frequency interval equates on frequency domain, comprise N SC-FDMA symbol simultaneously in time.It should be noted that SC-FDMA symbol mentioned above promptly can comprise long SC-FDMA symbol, also can comprise short SC-FDMA symbol.

For the convenience of narrating, the unified in the following description base unit that uses Resource Block to represent the up-downgoing dispatch channel resource of the present invention.For down direction, Resource Block is corresponding to local formula virtual resource blocks or distributed virtual resource block; For the up direction Resource Block corresponding to local formula Resource Unit or distributed resource units.

Shown in Figure 3 is the mode of the channel resource that distributes of existing a kind of base station indication, and control channel comprises two class channels at least, and the master control channel is used to send the number of the subscriber equipment of scheduling; Inferior control channel is used to send information such as the customer equipment identification that comprises scheduling and resource allocation.This method hypothesis base station is continuous for each user equipment allocation Resource Block.

1) base station sends the sign (301,302,303) of each subscriber equipment that current subframe need dispatch, thereby obtains comprising a table about customer equipment identification of the individual element of M (M is the number of user equipment of current subframe scheduling);

2) base station sends its type (311,312,313) to each Resource Block successively, thereby obtains the table of N element, and wherein N is the number of Resource Block in the system;

3) type of each Resource Block is mapped as individual bit, thereby total bit number that the indication resource allocation needs in the downlink signaling is N.

The step 2 of method shown in Figure 3) in, a kind of mode is that the current resource block assignments of definition bit 0 representative is given certain subscriber equipment, and next Resource Block is no longer distributed to this subscriber equipment simultaneously; The current resource block assignments of definition bit 1 representative is given certain subscriber equipment, and next Resource Block is still distributed to this subscriber equipment simultaneously.According to this rule, the base station obtains indexed resource assignment information bit block.Fig. 3 has shown an example (320) of this resource allocation information bit block, as shown in Figure 3, from left to right, " 0 " (321) represent that first resource block assignments is to subscriber equipment 1, thereafter these three resource block assignments are represented to subscriber equipment 2 in " 110 " (322), and last four resource block assignments in expression back, " 1110 " (323) are given subscriber equipment M.

The method of indexed resource assignment information as described in Figure 3 mainly contains two aspects to be needed to improve:

A) in this method,, contain a large amount of redundant informations in the type information of each Resource Block of base station transmits because the number of scheduling user's set has been transmitted in the base station.Can adopt suitable method to eliminate redundant information, thereby reduce the expense of control signaling.

B) this method can only be used for system all Resource Block in the current subframe are all distributed to the situation of subscriber equipment, yet several factors can cause system only to distribute a part in all Resource Block in certain subframe in the LTE system:

1) be divided into a plurality of groups when sending when the control signaling, the Resource Block that every group of subscriber equipment takies all will be a subclass of system's total resources piece, and method at this moment above-mentioned can not be worked;

2) in current discussion about LTE control signaling, the duration of resource allocation (Duration) is the mode of a very important reduction signaling consumption.When adopting this mode, the resource of distributing to certain subscriber equipment in subframe of system is effective in a plurality of subframes thereafter, this means that simultaneously system is when sub-frame allocation resource thereafter, just distribute these Resource Block resource in addition, just the part in the distribution system total resources piece;

3) owing to adopt channeling, thus the reliability that raising information is transmitted, such as the problem that solves cell boarder etc., a part of Resource Block in the system does not distribute in current subframe because of channeling, and method shown in Figure 3 can not be worked.

Embodiment

The present invention proposes the equipment and the method for indication channel resource allocation in a kind of wireless communication system, comprise the steps:

The operation of base station:

A) each subscriber equipment is given with resource block assignments in the base station;

B) Resource Block split position combined indexes in the channel resource that is distributed is indicated in the base station in the control signaling of distributing to the subscriber equipment indicating channel resource;

In the present invention, the base station has dual mode to transmit control channel: a kind of mode is that the base station is that indicating channel resource distributes two kinds of control channels of transmission, be respectively master control channel and time control channel, wherein the length of time control channel is decided by the part or all of information of indicating in the master control channel; Another kind of mode is that the base station is that indicating channel resource distributes a kind of control channel of transmission.

In the step a) of the present invention, the base station is given each subscriber equipment resource block assignments based on the channel quality indication (CQI) of subscriber equipment and the information such as data traffic information of subscriber equipment.The data traffic information of subscriber equipment is meant the data volume and the corresponding quality of service requirement of each subscriber equipment for descending, be meant the data volume and the corresponding quality of service requirement of the upstream data that each subscriber equipment is reported for up.

In the step b) of the present invention, a kind of processing mode is that the Resource Block number of grouping is continuously indicated in the base station in the master control channel, and is shown in Resource Block split position combined indexes in the channel resource that is distributed at inferior control channel middle finger.

The Resource Block continuously number of grouping is defined as follows: (N also is not equal to the total resources piece number of base station to establish assignable Resource Block number in the base station and be N, for example when the base station is transmitted distributed and local formula channel simultaneously in a descending subframe, the individual number average of the assignable Resource Block of distributed channel or local formula channel correspondence is less than the total resources piece number of base station), Resource Block R is promptly arranged ₁, R ₂..., R _N, work as R ₁..., R _A1Belong to subscriber equipment U ₁, R _A1+1..., R _A2Belong to subscriber equipment U ₂..., R _AN-1+1..., R _NBelong to subscriber equipment U _M, and subscriber equipment U _i≠ U _I+1, during 1≤i＜M, then claim Resource Block continuously the number of grouping be M.Please note in the middle of above-mentioned definition, unappropriated continuous resource piece can be regarded as belong to a special subscriber equipment (unappropriated resource only be meant this Resource Block this transmission in do not distribute to indicated subscriber equipment, in fact because resource can continue to distribute, these unappropriated Resource Block may be used by other subscriber equipmenies in this time transmission).It should be noted that in addition a subscriber equipment can distribute the continuous grouping of a plurality of Resource Block, but must guarantee between these Resource Block groupings discontinuous.For example when certain subscriber equipment has the continuous grouping of three Resource Block, i.e. U _i=U _j=U _k, during 1≤i＜j＜k≤M, require j＞i+1, k＞j+1.

Provide the example of four Resource Block groupings below.In the middle of example, suppose that all assignable Resource Block number is N=12 in the base station.

Resource Block grouping example one: in this example, all Resource Block all are assigned with, and all Resource Block of each subscriber equipment are all continuous.Shown in Fig. 2 a, subscriber equipment 1 is distributed to Resource Block 201 in the base station, Resource Block 202,203 and 204 is distributed to subscriber equipment 2, Resource Block 205 and 206 is distributed to subscriber equipment 3, Resource Block 207 is distributed to subscriber equipment 4, Resource Block 208,209 and 210 is distributed to subscriber equipment 5, and Resource Block 211 and 212 is distributed to subscriber equipment 6.In this example, the number of the continuous grouping of Resource Block is 6.

Resource Block grouping example two: in this example, all Resource Block all are assigned with, and all Resource Block of each subscriber equipment can be spaced apart.Shown in Fig. 2 b, subscriber equipment 1 is distributed to Resource Block 213,217 and 218 in the base station, and Resource Block 214,215,216,223 and 224 is distributed to subscriber equipment 2, and Resource Block 219 is distributed to subscriber equipment 3, and Resource Block 220,221 and 222 is distributed to subscriber equipment 4.Subscriber equipment 1 and subscriber equipment 2 respectively have two Resource Block to divide into groups continuously.In this example, the number of the continuous grouping of Resource Block is 6.

Resource Block grouping example three: in this example, have some Resource Block not to be assigned with, and all Resource Block of each subscriber equipment are all continuous.Shown in Fig. 2 c, subscriber equipment 1 is distributed to Resource Block 225 in the base station, and Resource Block 226,227 and 228 is distributed to subscriber equipment 2, and Resource Block 231 is distributed to subscriber equipment 3, and Resource Block 232,233 and 234 is distributed to subscriber equipment 4.Resource Block 229,230,235 and 236 is not assigned with.In this example, the number of the continuous grouping of Resource Block is 6.

Resource Block grouping example four: in this example, have some Resource Block not to be assigned with, and all Resource Block of each subscriber equipment can be spaced apart.Shown in Fig. 2 d, subscriber equipment 1 is distributed to Resource Block 237,241 and 242 in the base station, and Resource Block 238,239 and 240 is distributed to subscriber equipment 2, and Resource Block 244,245 and 246 is distributed to subscriber equipment 3.Subscriber equipment 1 has two Resource Block to divide into groups continuously.Resource Block 243,247 and 248 is not assigned with.In this example, the number of the continuous grouping of Resource Block is 6.

Assignable Resource Block number is N in the base station, and when the number that Resource Block divides into groups continuously was M, the number of the position that all Resource Block are cut apart can be derived as follows.This problem equivalent is in being divided into N Resource Block M grouping continuously, i.e. the number of the position that the number of combinations of the position that M-1 Resource Block of taking-up cut apart in the position that N-1 Resource Block cut apart, thereby all Resource Block is cut apart is

Number of combinations

Be meant from n different elements, take out m (number of all combinations of individual element of m≤n),

Can use formula $\left(\begin{array}{c}n\\ m\end{array}\right)=\frac{n!}{m!(n-m)!}$ Calculate.Because the number of the position that all Resource Block are cut apart is

The bit number of the signaling of indexed resource piece split position combined indexes is Wherein

Expression is to the x operation that rounds up.

Resource Block split position combined indexes is corresponding one by one with the combination of Resource Block split position.Assignable Resource Block number is N in the base station, and when the number that Resource Block divides into groups continuously was M, establishing Resource Block was R ₁, R ₂..., R _N, use sequence a ₁a ₂... a _N-1Come the combination of indexed resource piece split position.A wherein _i, 1≤i≤N-1 is illustrated in Resource Block R _iAnd R _I+1Between whether be the position that Resource Block is cut apart.For any a _i, 1≤i≤N-1, a _i=0 this position of expression is not the Resource Block split position, i.e. Resource Block R _iAnd R _I+1Belong to same subscriber equipment or all unallocated; a _i=1 this position of expression is the Resource Block split position, i.e. Resource Block R _iAnd R _I+1Belong to different subscriber equipmenies or one of them Resource Block is assigned to a subscriber equipment and another Resource Block is not assigned with.This sequence a ₁a ₂... a _N-1Also satisfy constraint simultaneously $\underset{i=1}{\overset{N-1}{\mathrm{\Σ}}}{a}_i=M-1$ (because the summation of Resource Block split position is M-1).With N=5, M=3 is an example, and the corresponding relation between the composite sequence of Resource Block split position combined indexes and Resource Block split position is as shown in table 1.In table 1, the composite sequence of index 0 correspondence is 0011, means that position that Resource Block cuts apart is at R ₃And R ₄Between, and R ₄And R ₅Between, i.e. Resource Block R ₁, R ₂And R ₃Be one group, Resource Block R ₄Be one group, Resource Block R ₅It is one group, shown in Fig. 4 a.The composite sequence of index 1 correspondence is 0101, means that position that Resource Block cuts apart is at R ₂And R ₃Between, and R ₄And R ₅Between, i.e. Resource Block R ₁And R ₂Be one group, Resource Block R ₃And R ₄Be one group, Resource Block R ₅It is one group, shown in Fig. 4 b.Index 2,3,4 and 5 implication can the rest may be inferred, respectively shown in Fig. 4 c, 4d, 4e and 4f.In table 1, the composite sequence of Resource Block split position is according to binary number a ₁a ₂... a _N-1The ascending order of size arrange i.e.: (0011) ₂＜(0101) ₂＜(0110) ₂＜(1001) ₂＜(1010) ₂＜(1100) ₂, a wherein ₁Be highest significant position, a _N-1Be least significant bit.Also can adopt other sortord, as the composite sequence of Resource Block split position according to binary number a ₁a ₂... a _N-1The descending of size arrange, perhaps arrange with other particular order.The sequence a of the combination of another indexed resource piece split position ₁a ₂... a _N-1Mode be, for any a _i, 1≤i≤N-1, a _i=0 this position of expression is the Resource Block split position, a _i=1 this position of expression is not the Resource Block split position.This sequence a ₁a ₂... a _N-1Also satisfy simultaneously $\underset{i=1}{\overset{N-1}{\mathrm{\Σ}}}{a}_i=N-M$ (because the summation of Resource Block split position is M-1).A in addition ₁a ₂... a _N-1Itself can be corresponding be a specific arrangement of spaced-apart locations.

Table 1 Resource Block split position combined indexes corresponding relation example

When the number of composite sequence hour, can store the mapping relations table between index and the composite sequence.When the number of composite sequence more for a long time, the mode of this storage can need a large amount of internal memories.Provide below one general from number of combinations sequence computation index or from the algorithm of index calculation number of combinations sequence.If composite sequence a ₁a ₂... a _NCorresponding to number of combinations

For any a _i, 1≤i≤N, a _i=1 expression element i is selected, and a _i=0 expression element i is not selected a ₁a ₂... a _NAlso satisfy constraint simultaneously $\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{a}_i=M.$ Composite sequence is according to binary number a in addition ₁a ₂... a _NThe ascending order of size arrange.Provided respectively from composite sequence a among Figure 11 and Figure 14 ₁a ₂... a _NCalculate the algorithm of manipulative indexing index, and calculate corresponding composite sequence a from index index ₁a ₂... a _NAlgorithm.For example, work as N=4, during M=2, as composite sequence a ₁a ₂... a _NBe 1010 o'clock, can determine index=4 by the algorithm of Figure 11; And when index=3, can determine composite sequence a by the algorithm of Figure 14 ₁a ₂... a _NBe 1001.Because the complexity of this algorithm only increases along with N is linear, thereby be convenient to very much realize.

After the base station was given each subscriber equipment according to step a) of the present invention with resource block assignments, when assignable Resource Block number was N in the base station, the continuous number M of dividing into groups of Resource Block is indicated in the base station in the master control channel (the signaling bit number that needs was

), the base station is mapped as the allocation situation of resource the composite sequence a of Resource Block split position ₁a ₂... a _N-1, and according to the corresponding relation of composite sequence and index obtain Resource Block split position combined indexes and in inferior control channel this index of indication (the signaling bit number that needs is

).The signaling of the signaling of master control channel and time control channel is carried out chnnel coding respectively.Can also comprise other control information in the master control channel.Also can comprise other control information in the inferior control channel.For example, the sign of all subscriber equipmenies of this scheduled transmission can be transmitted in the base station in inferior control channel, the order of customer equipment identification is corresponding with its order in resource allocation, and promptly identical with resource allocation order occurs, or the order opposite with resource allocation occurs.When some Resource Block was not distributed to indicated subscriber equipment in this transmission, the base station was at the customer equipment identification of a reservation of location transmission of the customer equipment identification of correspondence, and the subscriber equipment in this sub-district does not use the customer equipment identification of this reservation.Subscriber equipment can be known the customer equipment identification of these reservations, also can not know the customer equipment identification (because not influencing the operate as normal of subscriber equipment) of these reservations.With Fig. 4 is example, and when the base station was given 3 users in the mode of Fig. 4 c with 5 resource block assignments, the base station was used in the master control channel

The number that signaling comes the indexed resource piece to divide into groups continuously is 3, because pairing composite sequence is 0110, be 2 thereby can get its corresponding index by table 1, so the base station is being used in inferior control channel

Signaling is indicated this index.

In this processing mode, another mode is corresponding to specific system bandwidth, and the Resource Block number of grouping is continuously fixed.For example for the 5MHz system bandwidth, the Resource Block number of grouping continuously is 4.The base station only need be shown in that Resource Block split position combined indexes gets final product in the channel resource that is distributed at the control channel middle finger like this.

In this processing mode, another mode is semi-static ground, the base station resource allocation piece number of grouping continuously.For example by the continuous number of dividing into groups of broadcast channel resource allocation piece.The base station only need be shown in that Resource Block split position combined indexes gets final product in the channel resource that is distributed at the control channel middle finger like this.

In the step b) of the present invention, another kind of processing mode is that the Resource Block number and the continuous number of dividing into groups of unallocated Resource Block of grouping are continuously indicated in the base station in the master control channel, and is shown in Resource Block split position combined indexes and the continuous packet positions combined indexes of unallocated Resource Block in the channel resource that is distributed at inferior control channel middle finger.

As indicated above, some Resource Block may not distributed to indicated subscriber equipment in this transmission.According to a kind of processing mode in the step b) mentioned above is to regard these unappropriated Resource Block as a special subscriber equipment and transmit a corresponding customer equipment identification that keeps.When in the transmission the continuous grouping of a plurality of unallocated Resource Block being arranged, need a plurality of special customer equipment identifications of transmission, can produce bigger signaling load like this.

In this processing mode, the Resource Block number and the continuous number of dividing into groups of unallocated Resource Block of grouping are continuously indicated in the base station in the master control channel.The unallocated Resource Block number of grouping continuously is meant in Resource Block divides into groups continuously, does not distribute to the number of the continuous grouping of subscriber equipment.With Fig. 2 is example, and in Fig. 2 a and 2b, the unallocated Resource Block number of grouping continuously is 0; And in Fig. 2 c and 2d, the unallocated Resource Block number of grouping continuously is 2.The mode of other two kinds of equivalences is number and continuous numbers of dividing into groups of distributes resource blocks that the indication Resource Block divides into groups continuously in the master control channel, and number that the unallocated Resource Block of indication divides into groups continuously in the master control channel and the continuous number of dividing into groups of distributes resource blocks.Wherein the number of the continuous grouping of distributes resource blocks is meant in Resource Block divides into groups continuously, distributes to the number of the continuous grouping of subscriber equipment.With Fig. 2 is example, and in Fig. 2 a and 2b, the distributes resource blocks number of grouping continuously is 6; And in Fig. 2 c and 2d, the distributes resource blocks number of grouping continuously is 4.Because number that the number that Resource Block divides into groups continuously, unallocated Resource Block divide into groups continuously and the distributes resource blocks number of grouping continuously satisfy following relation:

Resource Block is the number of the continuous grouping of number=unallocated Resource Block of grouping continuously

+ distributes resource blocks number thereby above-mentioned three kinds of modes of grouping continuously is equivalent.In the following description of the present invention, will corresponding processing mode be described with number and the continuous this mode of number of dividing into groups of unallocated Resource Block that indication Resource Block in the master control channel divides into groups continuously.

The number and the continuous number of dividing into groups of unallocated Resource Block of grouping have three kinds of processing modes to the indication Resource Block continuously in the master control channel.In the following description, establish when assignable Resource Block number is N in the base station, the Resource Block number of grouping continuously is M, and the unallocated Resource Block number of grouping continuously is Q, and the distributes resource blocks number of grouping continuously is P=M-Q.It should be noted that Q must satisfy condition

(because the number Q that unallocated Resource Block divides into groups continuously≤P+1), when M was unknown, Q must satisfy condition

The unallocated like this Resource Block number Q of grouping continuously has at most

Individual value.

Method 1: base station number that difference indexed resource piece divides into groups continuously in the master control channel and unallocated Resource Block be the number of grouping continuously.The signaling bit number of Xu Yaoing is like this

Method 2: base station number that the joint instructions Resource Block divides into groups continuously in the master control channel and unallocated Resource Block be the number of grouping continuously.The signaling bit number of Xu Yaoing is like this

This method can ratio method 1 be saved signaling consumption in some cases.A kind of implementation of this method is indication Q*N+ (M-1), and another implementation is indication In addition similar implementation can also be arranged, not give unnecessary details one by one at this.
