Embodiment one:

As shown in Figure 1, a kind of flow diagram of the resource allocation methods provided for the embodiment of the present invention one.The method It can be as described below.

Step 101: base station equipment determines the first Transmission Time Interval (TTI).

In a step 101, the TTI as specified in current LTE system is generally 1ms, herein base station equipment determine the One TTI is TTI specified in agreement, can be 1ms.

Step 102: when base station equipment determines that the 2nd TTI of current system is N/TTI, determining for carrying number According to Physical Resource Block PRB and virtual resource blocks between mapping relations.

Wherein, the resource block mapping of the carrying data contains carrying in the first virtual resource block number and a time slot The number and a time slot of mapping relations or the first virtual resource blocks pair between two Physical Resource Block PRB number of data Mapping relations between two Physical Resource Block PRB number of interior carrying data.

In a step 102, the 1ms as specified in current agreement requires relatively high communication service transmission time Say that time span is longer, therefore, the 2nd TTI of base station equipment current system is first as defined in agreement in the embodiment of the present invention N/mono- of TTI, wherein N is the positive integer greater than 1.

The shortening of Transmission Time Interval means the change of resource distribution mode in system.

In embodiments of the present invention, what is followed the steps below so that the current TTI value of system is 0.5ms as an example retouches in detail It states.

It should be noted that the first virtual resource blocks can be referred to as the virtual resource blocks (English: Enhanced of enhancing again Virtual Resource Block；Abbreviation: EVRB).

Since base station equipment uses the Transmission Time Interval short compared with 1ms, then will be adjusted according to the Transmission Time Interval Resource allocation granularity significantly reduces the signaling overheads of Downlink Control Information.

Specifically, first way: base station equipment is established in the first virtual resource block number and a time slot and carries data Two PRB number between mapping relations.

The second way: base station equipment establishes the number and two of carrying data in a time slot of the first virtual resource blocks pair Mapping relations between a PRB number.

For above two mode, two PRB number of carrying data can be continuous two PRB and compile in a time slot Number, it is also possible to discrete two PRB number.

Wherein, continuous two PRB of the first virtual resource blocks (to) number and carrying data in a time slot are numbered Between mapping relations, be otherwise known as centralization resource impact relationship；One the first virtual resource blocks (to) is numbered and one Mapping relations in time slot between discontinuous two PRB number of carrying data, be otherwise known as distributed resource impact relationship.

Such as: for the resource impact relationship of centralization, the number of the first virtual resource block number is equal to of PRB number Several halfs, the value range of the number of PRB number are as follows:Wherein,To be used for transmission downlink data Resource block (English: Resource Block；Abbreviation: RB) number,It is referred to as band width configuration parameter.

In an obtained first virtual resource block number and a time slot between continuous two PRB number of carrying data Mapping relations are as follows: EVRB { 0 } <-> PRB { 0,1 }；EVRB { 1 } <-> PRB { 2,3 }；EVRB { 2 } <-> PRB { 4,5 } Deng.

Obtained first virtual resource blocks number it to continuous two PRB for carrying data in number and a time slot Between mapping relations are as follows: EVRB { 0,0 } <-> PRB { 0,1 }；EVRB { 1,1 } <-> PRB { 2,3 }；EVRB { 2,2 } <-> PRB { 4,5 } etc..

For distributed resource impact relationship, number is carried in the first virtual resource blocks (to) number and a time slot According to discontinuous two PRB number between mapping relations, then discontinuous two PRB number between difference meet LTE association Spacing parameter (GAP) value defined in discussing.

It should be noted that the size of GAP value, regulation depends on system bandwidth in LTE protocol.Such as: such as 1 institute of table Show, according to different system bandwidths, obtain the of different sizes of GAP value:

Table 1

Assuming that the difference between discontinuous two PRB number is 18, then an obtained first virtual resource block number Mapping relations between numbering with discontinuous two PRB for carrying data in a time slot are as shown in table 2:

EVRB number	PRB number
		EVRB{0}	PRB { 0,18 }
EVRB{1}	PRB { 6,24 }
		EVRB{2}	PRB { 1,19 }
EVRB{3}	PRB { 7,25 }
		EVRB{4}	PRB { 2,20 }
EVRB{5}	PRB { 8,26 }
