The base station at first renumbers 24 DRU and is DRU according to certain specific order ₀, DRU ₁, DRU ₂..., DRU ₂₂, DRU ₂₃, determine the content of resource allocation indication signaling then with these two parameters of number of the DRU of the initial logical number of the DRU that distributes and distribution.

For the situation of partition size, use 7 bits to represent assignment information less than 15 DRU.For example, when distributing a DRU to the user, and that distribute is DRU ₀The time, use 7 table of bits to be shown 0000000 (the indication index of decimal representation is 0); When distributing a DRU to the user, and that distribute is DRU ₁The time, use 7 table of bits to be shown 0000001 (the indication index of decimal representation is 1); When distributing a DRU to the user, and that distribute is DRU ₂The time, use 7 table of bits to be shown 0000010 (the indication index of decimal representation is 2) ...; When distributing 2 DRU to the user, and that distribute is DRU ₀, DRU ₁The time, use 7 table of bits to be shown 0011000 (the indication index of decimal representation is 24); When distributing 2 DRU to the user, and that distribute is DRU ₁, DRU ₂The time, use 7 table of bits to be shown 00110001 (the indication index of decimal representation is 25); The rest may be inferred, when the user has distributed 15 DRU (DRU ₉～DRU ₂₃) time, 7 bit signallings are encoded to 1110111 (the indication index of decimal representation is 119).

Above-mentioned situation is organized into table, when using high order bit when preceding, with as shown in table 5 below:

Table 5

For example, in the present embodiment, the base station sends the basic distribution control information unit that DRU distributes type in order to distribute maximum particle size to be no more than 15 DRU to certain user to this user.In the control information unit, use a sign that takies several bits (such as 4 bits), the resource that identifies this distribution is the DRU type, and maximum particle size is no more than 15 logical resource block.If distributing 7 bit indication signalings in the control information unit substantially is 1000011 (decimal system is 67), then the user receives this indication signaling, can draw the base station according to last table 5 and distribute 3 DRU to the user, and its logical number is since 20, promptly, distributed that { 20,21, these three DRU of 22} give this user.

For the situation of partition size greater than 15 DRU, use 9 bits to represent assignment information, wherein, preceding 5 bits are represented the original position of distributing, back 4 bits are represented allocated size (16～24).For example, when distributing 16 DRU to the user, and that distribute is DRU ₀～DRU ₁₅The time, preceding 4 bits, 00000 expression original position is DRU ₀, the resource size that back 4 bits, 0000 expression distributes is 16 DRU.In the present embodiment, the base station sends this distribution of expansion base control information unit that DRU distributes type in order to distribute maximum particle size to surpass 15 DRU to certain user to this user.In the control information unit, use the sign of several bits (such as 4 bits), this resource that identifies distribution is the DRU type, and the resource number of distributing surpasses 15 logical resource block.Wherein, 9 bit indication signalings are 001000010.The user receives this indication signaling, resolves preceding 4 bits and knows that the unit of distribution is from the 4th DRU (DRU ₃) beginning, resolve back 4 bits and know that resource size is 18 DRU.

For example, in the present embodiment,, send the basic distribution control information unit that DRU distributes type to this user in order to distribute maximum particle size to be no more than 44 DRU to certain user.In the control information unit, use a sign that takies several bits (such as 4 bits), the resource that identifies this distribution is the DRU type, and maximum particle size is no more than 44 logical resource block.Wherein, 10 bit indication signalings are 0010111010 (decimal system is 190), and the user receives this indication signaling, can draw the base station according to last table 7 and distribute 2 DRU to the user, and its logical number promptly, distributed DRU{94 since 94, and 95} gives this user.

For the situation of partition size greater than 44 DRU, use 13 bits to represent assignment information, wherein, preceding 7 bits are represented the original position of distributing, back 6 bits are represented allocated size (45～96).For example, when distributing 45 DRU to the user, and that distribute is DRU ₀～DRU ₄₄The time, preceding 7 bits, 0000000 expression original position is DRU ₀, the resource size that back 6 bits, 000000 expression distributes is 45 DRU.In the present embodiment, the base station sends this distribution of expansion base control information unit that DRU distributes type in order to distribute maximum particle size to surpass 44 DRU to certain user to this user.In the control information unit, use the sign of several bits (such as 4 bits), this resource that identifies distribution is the DRU type, and the resource number of distributing surpasses 44 logical resource block.Wherein, 13 bit indication signalings are 0,000,010 000010, and the user receives this indication signaling, resolve preceding 7 bits and know that the unit of distribution is since the 3rd DRU (DRU ₂), resolve back 6 bits and know that the size of Resources allocation is 47 DRU.

As mentioned above, because the distribution of carriers characteristics of DRU on frequency domain, the base station is when distributing the resource of corresponding D RU, often carry out continuous dispensing, promptly, the logical number of at every turn distributing to a user's DRU is continuous, and in order to indicate corresponding D RU position and length, the distribution of using 10 bits to indicate corresponding D RU in the control information will be distributed substantially in each clean culture in the base station.

The base station is at first with FP ₀, FP ₁, FP ₂, FP ₃In 48 DRU altogether renumber according to certain specific order and be DRU ₀, DRU ₁, DRU ₂..., DRU ₄₆, DRU ₄₇, for example, according to from FP ₀To FP ₃Order, respectively with FP ₀In 24 DRU (be FP ₀In DRU ₀～DRU ₂₃) be numbered DRU ₀～DRU ₂₃, with FP ₁In 8 DRU (be FP ₁In DRU ₀～DRU ₇) be numbered DRU ₂₄～DRU ₃₁, with FP ₂In 8 DRU (be FP ₂In DRU ₀～DRU ₇) be numbered DRU ₃₂～DRU ₃₉, with FP ₃In 8 DRU (be FP ₃In DRU ₀～DRU ₇) be numbered DRU ₄₀～DRU ₄₇, these two parameters of number of the DRU of the initial logical number of the DRU of usefulness distribution and distribution are come unique content of determining 10 bit indication signalings then.

For example, when distributing a DRU to the user, and that distribute is DRU ₀The time, use 10 table of bits to be shown (low-order bit when preceding or high order bit when preceding) 0x00; When distributing a DRU to the user, and that distribute is DRU ₁The time, use 10 table of bits to be shown (low-order bit is when preceding) 0x200 or (high order bit is when preceding) 0x001; When distributing a DRU to the user, and that distribute is DRU ₂The time, use 10 table of bits to be shown (low-order bit is when preceding) 0x100 or (high order bit is when preceding) 0x002; When distributing 2 DRU to the user, and that distribute is DRU ₀, DRU ₁The time, use 10 table of bits to be shown (low-order bit is when preceding) 0x030 or (high order bit is when preceding) 0x030; When distributing 2 DRU to the user, and that distribute is DRU ₁, DRU ₂The time, use 10 table of bits to be shown (low-order bit is when preceding) 0x230 or (high order bit is when preceding) 0x031.The rest may be inferred, if distributed 48 DRU to the user, then only has a starting point this moment, and 10 bit signallings are encoded to (low-order bit is when preceding) or 0x1ff or (high order bit is when preceding) 0x3fe.
