Embodiment
The scheduling status indication method of communication system provided by the invention comprises:
The base station generates corresponding dispatch information according to the dispatch state to user equipment (UE);
The schedule information item that is relative to each other in the described dispatch information is carried out sending dispatch to UE behind the combined coding.
The basic principle of the inventive method is: because part dispatch information is not fully independently, in fact there is certain inherent correlation in each schedule information item, promptly in case wherein a certain value is decided, the optional scope of other several values can be dwindled thereupon.
The present invention is based on arbitrary user, distribute the continuous physical resource unit, schedule information item relevant in the dispatch information is carried out combined coding, consider the possible assembled state of necessary being, that exist when rejecting the coding separately and actual compound mode that may not exist, significantly reduce the sum of assembled state, thereby reach the purpose that reduces the dispatch overhead bit.
Consider that the schedule information that will transmit is to inform that the recipient will send the size of the data block of (or reception), physical source distributing information (positional information and the quantity information that comprise the physical resource unit of distribution, wherein, the positional information of the physical resource unit of distribution can be the start position information or the end position information of the physical resource unit of distribution.) and adopt which kind of modulating-coding form.These schedule informations are correlated with, and have notified a wherein part, and a part can be calculated out in addition; And also have certain correlation between the each several part of notice, and can carry out combined coding, need the occupied signaling bit with further minimizing.Wherein, transport block size information is to transmit with the positional information of distributing to the physical resource unit of UE, because this part information can't be calculated out.After above-mentioned information notice, in view of physical resource unit quantity information that distributes and the relation between the modulating-coding form, only notice wherein any one.
With specific embodiment the inventive method is described in detail below.
Embodiment 1:
The dispatch information that is handed down to UE comprises the physical source distributing information of UE identification information, UE (positional information that comprises physical resource unit, the physical resource unit quantity information of distribution), transport block size information at least; Wherein, physical source distributing information and the transport block size information of UE are carried out combined coding, all the other information absolute codings.
Concrete combined coding mode can be:
Earlier the positional information of the physical resource unit of distributing to UE and the physical resource unit quantity information that takies are carried out first order combined coding;
Carry out second level combined coding in conjunction with transport block size information again.
Physical source distributing information has following two kinds of typical method for expressing.
Method one: the positional information of the physical resource unit that explicit indication distributes and the physical resource unit quantity information of distribution.Provide the absolute position of physical resource unit in the system physical Resource Unit and the quantity of distribution of distributing to certain UE, as shown in Figure 1: the total physical resource unit of system is 10, what distribute to UEA is from numbering 43 physical resource unit to numbering 6, during the physical source distributing information of so explicit indication UE, 4 and 3 the information of directly providing gets final product.The independent according to the method respectively separately indication of the resource allocation information of a plurality of UE.
Method two: non-explicit indication distributes the positional information of physical resource unit and the physical resource unit quantity information of distribution.According to the dependence that physical resource unit between many UE is distributed, unite the physical source distributing information that provides all UE.As shown in Figure 2: the corresponding physical resource unit of bit, value is last physical resource unit of distributing to certain UE for " 0 " represents this bit corresponding physical Resource Unit, and value is not last physical resource unit of distributing to certain UE for " 1 " represents this bit corresponding physical Resource Unit.The total physical resource unit of system is 10, can determine according to the number of " 0 " in 10 bits and to have given 5 UE, the square of filling different rulings among distribution condition such as Fig. 2 is represented, the UE id information is according to the resource allocation conditions ordering of reality, and each UE can find the physical resource of distributing to oneself according to the order correspondence of self ID so.The disposable joint instructions of the resource allocation information of a plurality of UE.
No matter pass through the method for expressing of above the sort of resource allocation information, represented information all is to distribute to the positional information of the physical resource unit of UE, the physical resource unit quantity information of distribution.
Directly physical source distributing information and transport block size information are carried out combined coding in the present embodiment 1.
When the physical source distributing information of UE and transport block size information are carried out combined coding, reduce the signaling bit number and make a concrete analysis of below:
Referring to Fig. 3, the numbering of all transmission block sizes of supporting in the line display system of matrix; The quantity of different distribution physical resource unit is shown in tabulation, can map out the kind number of the transmission block size that can support according to the quantity of the physical resource unit of distributing.If corresponding to the quantity of the physical resource unit of certain distribution, can support certain transmission block size, then this corresponding element is changed to " 1 " in the matrix, otherwise is changed to " 0 ".Fig. 3 only is a schematic diagram, corresponding to the quantity of the physical resource unit of certain distribution, can only support the kind number of one group of transmission block size, only is a very little part in the big small set of transmission block.As can be seen from Figure 3, this matrix class is similar to a unit matrix, and having only diagonal element and near element thereof is 1, and most elements all is 0.Like this,, signaling consumption can be significantly saved, 1 bit can be saved at least if physical source distributing information and transport block size information are carried out combined coding.
After UE receives dispatch, parse schedule information; When schedule information is the down dispatch information of indication UE, carry out the following step:
A1, determine order of modulation and the encoder bit rate (if modulation format and encoder bit rate are regarded as a variable, UE can calculate the modulation format and the encoder bit rate of actual employing according to formula (1)) that adopt the base station by the schedule information that parses;
A2, receive respective data blocks, carry out the demodulation processing with order of modulation of determining and encoder bit rate according to the positional information of distributing to own physical resource unit and the physical resource unit quantity information that takies;
When schedule information is the uplink scheduling information of indication UE, carry out the following step:
B1, determine order of modulation and the encoder bit rate that indication UE in base station adopts by the schedule information that parses;
B2, according to the positional information of distributing to own physical resource unit and the physical resource unit quantity information that takies, take corresponding physical resource unit and send data, the order of modulation that usefulness is determined and encoder bit rate is modulated and encoding process.
Embodiment 2:
The dispatch information that is handed down to UE comprises UE identification information, transport block size information at least, distributes to positional information and the modulation intelligence and the coded message of the physical resource unit of UE; Wherein, only modulation intelligence and coded message are carried out combined coding, all the other information absolute codings.
Based on the physical source distributing information method for expressing of mentioning among the embodiment 1 one, can think that the positional information and the quantity information of the physical resource unit of distributing represent respectively, in the present embodiment, the quantity information that does not comprise the physical resource unit of distributing to UE in the dispatch information, but need to increase the coded message (encoder bit rate) of coarseness, promptly do not need very accurate encoder bit rate information, selecting the purpose of coarseness is in order to reduce signaling consumption.The encoder bit rate information of the coarseness that increases guarantees that in the physical resource unit quantity of distributing be under the situation of k, needn't accurately represent.Select the encoder bit rate of approaching a kind of coarseness according to the accurate encoder bit rate of reality employing, the principle of selecting can be guarantee physical resource unit quantity through dispensed at (k-1) between the k, promptly adopt to high code rate and dress the mode of on the basis of former code check data, punching again that is similar to, hereinafter to be referred as the punching principle; Be under the situation of k perhaps in the physical location quantity of distributing, the principle of selecting can be to guarantee to arrive between (k+1) at k through the physical resource unit quantity of dispensed, promptly adopt to low code check and dress the Reduplicated mode on the basis of former code check data that is similar to, hereinafter to be referred as repeating principle.The purpose of notice encoder bit rate is in order to make UE calculate the shared physical resource unit quantity of data block roughly according to formula (1) according to the schedule information of all notices.When the quantity of the physical resource unit that is calculated is not integer, according to a preconcerted arrangement,, round up so if adopt the punching principle; Repeat principle if adopt, round so downwards.
For example: suppose to take k physical resource unit, and can not guarantee usually that according to the combined coding information of above-mentioned dispatch information report modulation information and encoder bit rate (the just encoder bit rate information of coarseness) UE is an integer according to the physical resource unit quantity that formula (1) calculates, so just select and the actual immediate coarseness encoder bit rate of the encoder bit rate information that adopts, as the quantity that makes the physical resource unit that UE calculates according to the punching principle greater than (k-1) smaller or equal to k, promptly be chosen in the encoder bit rate that continues to increase punching after the actual coding.The quantity that UE gives tacit consent to the physical resource unit that this data block takies rounds up and is k.After the quantity of actual physical resources unit was determined, on the one hand, the number of modulation symbols that it can carry is also corresponding determined that like this, UE can calculate the accurate encoder bit rate of actual employing according to above-mentioned formula (1); On the other hand, just physical source distributing information can have been determined in conjunction with the positional information of physical resource unit.
When modulation intelligence and coded message are carried out combined coding, reduce the signaling bit number and make a concrete analysis of below.
The modulation format quantity that the system of setting up departments is supported is N
MKind, the quantity of the encoder bit rate of the coarseness of support is N
CKind, if do not carry out combined coding, then transmit this two kinds of informational needs [log

Difference through type (4) between the two calculates:

Embodiment 3:
The dispatch information that is handed down to UE comprises UE identification information, transport block size information, the positional information of distributing to the physical resource unit of UE, modulation intelligence and coded message at least; Wherein, only transport block size information and the positional information of distributing to the physical resource unit of UE are carried out combined coding, all the other information absolute codings.
By the analysis of embodiment 2 as can be known: UE can be by calculating the schedule information of whole needs.
When transport block size information and the positional information of distributing to the physical resource unit of UE are carried out combined coding, reduce the signaling bit number and make a concrete analysis of below:
Referring to Fig. 4, the numbering of all transmission block sizes of supporting in the line display system of matrix; Different physical resource unit start position numberings is shown in tabulation, from certain physical resource unit starting point, can map out the kind number of the transmission block size that can support according to the quantity of the physical resource unit that may take.If from certain starting point, can support certain transmission block size, then this corresponding element is changed to " 1 " in the matrix, otherwise is changed to " 0 ".As seen from Figure 4, along with after the starting point of physical resource unit leans on gradually, the quantity that begins the physical resource unit that can take from this starting point reduces gradually so, and the kind number of the transmission block size that can support also reduces thereupon.An extreme case is when the starting point of physical resource unit is N
RU-1 o'clock, when promptly starting point is last physical resource unit, so only can take a physical resource unit, at this moment must only support a few transmission block size, only be a very little part in the big small set of transmission block.As can be seen from Figure 4, this matrix class is similar to a diagonal matrix, and the element that half is arranged is 0.Like this, if physical resource unit start position information and transport block size information are carried out combined coding, can save 1 bit at least.
Describe with concrete an enforcement below:
The physical resource unit quantity of uniting of setting up departments is 48, and the big smallest number of the transmission block of support is 100, and modulation system is 4 kinds, and the coded format of coarseness is 8 kinds, needs 6 users of scheduling now, and the signaling bit number that then adopts the prior art scheme to need is calculated as follows:
Distributing to the original position of the physical resource unit of UE calculates by following formula (5) with the bit number that the physical resource unit quantity information that takies needs:
[log
248]+([log
248] (bit) (5)-1)=11
The bit number that transport block size information needs calculates by following formula (6):
[log
2100] (bit) (6)=7
The bit number that modulation format information needs calculates by following formula (7):
[log
24] (bit) (7)=2
Then the required total signaling bit number of dispatch information is: 11+7+2=20 (bit).
The signaling bit number that adopts said method of the present invention to need is calculated as follows:
The bit number that distributing to the start position information of the physical resource unit of UE needs calculates by following formula (8):
[log
248] (bit) (8)=6
The bit number that transport block size information needs calculates by following formula (9):
[log
2100]-1=6 (bit) (9)
The bit number that modulation format information needs calculates by following formula (10):
[log
24] (bit) (10)=2
The required bit number of encoding format information calculates by following formula (11):
[1og
28] (bit) (11)=3
The required total signaling bit number of modulation signaling is: 6+6+2+3=17 (bit).
Hence one can see that, adopts the present invention to reduce the required total signaling bit number of dispatch information.
In said method of the present invention, after in case the transmission block size is determined, so optionally modulation format and coded format scope also can diminish, but need the set of concrete transmission block size value set and concrete modulating-coding form and every kind of transmission block size and the corresponding relation of modulation format encoding format information could release the minimizing situation of bit, and these information meetings because of the difference of system difference.In the aforementioned calculation process, the minimizing of concrete amount of bits is not counted; If only consider optional modulation format and coded format, the amount of bits that needs may further reduce.
Embodiment 4:
The dispatch information that is handed down to UE comprises UE identification information, transport block size information, the positional information of distributing to the physical resource unit of UE, modulation intelligence and coded message at least; Wherein, transport block size information and the positional information of distributing to the physical resource unit of UE are carried out combined coding; And described modulation intelligence and coded message carried out combined coding, all the other information absolute codings.
Embodiment 5:
The dispatch information that is handed down to UE comprises UE identification information, transport block size information, the positional information of distributing to the physical resource unit of UE, modulation intelligence and coded message at least; Wherein, transport block size information, the positional information of distributing to the physical resource unit of UE, modulation intelligence and coded message are carried out combined coding, all the other information absolute codings.
