For example, when distribute 3 CLRU basic allocation unit (or claiming subband) to the user, and that distribute is Subband0, Subband2, during Subband8, the base station can judge that obviously 3 basic allocation unit (or claiming subband) that need this moment to distribute are all in the G1 of group, then, only a resource allocation territory need be set in A-MAP IE, wherein, the resource allocation territory that is total up to 13 bits is binary system (left side is for high-order) 0b1100100000101.

For example, when distribute 4 CLRU basic allocation unit (or claiming subband) to the user, and that distribute is Subband0, Subband2, during Subband23, the base station can judge that obviously 3 basic allocation unit (or claiming subband) that need this moment to distribute are not entirely in the G1 of group, then, two resource allocation territories need be set in A-MAP IE, and wherein, first resource allocation territory that is total up to 13 bits is binary system (left side is for high-order) 0b1000000000101.And second the resource allocation territory that is total up to 13 bits is binary system (left side is for high-order) 0b1000000000000.

When distributing CLRU for unicast user, the base station uses the resource allocation territory of 12 bits to carry out the resource indication, and the base station is at first with FP ₀, FP ₁, FP ₂, FP ₃In 24 CLRU basic allocation unit altogether (or claiming subband), renumber according to certain specific order and to be Subband ₀, Subband ₁, Subband ₂..., Subband ₁₀, Subband ₂₃, for example, according to from FP ₀To FP ₃Order, respectively with FP ₀In 6 CLRU basic allocation unit (or claim subband) (be FP ₀In Subband ₀～Subband ₅) be numbered Subband ₀～Subband ₅, with FP ₁In 6 basic allocation unit (or claim subband) (be FP ₁In Subband ₀～Subband ₅) be numbered Subband ₆～Subband ₁₁, with FP ₂In 6 CLRU basic allocation unit (or claim subband) (be FP ₂In Subband ₀～Subband ₅) be numbered Subband ₁₂～Subband ₁₇, with FP ₃In 6 CLRU basic allocation unit (or claim subband) (be FP ₃In Subband ₀～Subband ₅) be numbered Subband ₁₈～Subband ₂₃These 12 basic allocation unit (or claiming subband) are divided into 2 groups, first group of G ₁In comprise Subband ₀～Subband ₉Totally 10 basic allocation unit (or claiming subband), second group of G ₂In comprise Subband ₁₀～Subband ₂₃, totally 14 basic allocation unit (or claiming subband).The base station can use 1 bit in 12 bits in the current resource allocation message (A-MAP IE) (such as highest order b in resource allocation message ₁₁Bit) the current distribution type of expression is discontinuous or continuous (it is discontinuous to put 1 expression), uses 1 bit (such as b again ₁₀) entirely in the G1 group, the basic allocation unit that 1 expression is distributed (or claiming subband) is entirely at first group of G for the resource of the current distribution of expression ₁In, the basic allocation unit that 0 expression is distributed (or claiming subband) is not entirely at G ₁In.If this bit puts 1, represent that then this resource allocation only needs a resource allocation territory in the resource allocation message (A-MAP IE), the base station in this resource allocation message with 10 other bits, which has been instructed to be used for indicating 10 basic allocation unit (or claiming subband) of corresponding G1 group, if for example the most significant bit in this 10 bit is 1, represent that then the basic allocation unit (or claiming subband) of the largest logical sequence number in corresponding basic allocation unit (or claiming subband) group has been assigned with.If this bit (b ₁₀) put 0, the resource of then representing this resource allocation is not entirely in G1, in G2, also has resource allocation, this sub-distribution need want in the resource allocation message (A-MAP IE) two resource allocation territories are arranged, the base station in this resource allocation message with 10 other bits, which has been instructed to be used for indicating 10 basic allocation unit (or claiming subband) of corresponding G1 group, if for example the significant bits in this 9 bit is 1, the basic allocation unit (or claiming subband) of then representing minimum (logic) sequence number in corresponding basic allocation unit (or claiming subband) group has been assigned with, and in next resource allocation territory, be used for indicating which basic allocation unit (or claiming subband) of G2 to be assigned with 12 bits in the 12 whole bits.

For example, when distribute 3 CLRU basic allocation unit (or claiming subband) to the user, and that distribute is Subband0, Subband2, during Subband8, the base station can judge that obviously 3 basic allocation unit (or claiming subband) that need this moment to distribute are all in the G1 of group, then, only need establish a resource allocation territory in A-MAP IE, wherein, the resource allocation territory that is total up to 12 bits is binary system (left side is for high-order) 0b110100000101.

For example, when distribute 4 CLRU basic allocation unit (or claiming subband) to the user, and that distribute is Subband0, Subband2, during Subband22, the base station can judge that obviously 3 basic allocation unit (or claiming subband) that need this moment to distribute are not entirely in the G1 of group, then, two resource allocation territories need be set in A-MAP IE, wherein, first resource allocation territory that is total up to 12 bits is binary system (left side for high-order) 0b100000000101, and second the Resources allocation allocation domain that is total up to 12 bits is binary system (left side is for high-order) 0b1000000000000.

Embodiment 18:

In the present embodiment, suppose to have a 5MHz system (this system use 512 FFT), because 5MHz one has 24 PRU, so the subband that can to generate 6 at most be group with 4 CLRU.The continuous CLRU of per four logics forms a subband (Subband).On the whole like this bandwidth, at most only have 6 subbands altogether.According to present embodiment, can in the resource allocation territory, use one or more bits to indicate the number of the CLRU that a basic allocation unit comprises.

Give (Continus Logical ResourceUnit for unicast user distribution CLRU in the base station, the continuous resource unit) time, the base station can be according to the number of sub-bands that exists in the system, different basic allocation unit is set, thereby uses resource allocation territory to carry out the resource indication with different bit numbers.

For example, suppose that base station system uses 11 bits to indicate altogether in the resource allocation territory, in the time of no more than 5 of the number of sub-bands that exists in the system, resource allocation and indication can be carried out with 2 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, have only 10 basic allocation unit (being that every unit contains 2 continuous CLRU) so in the system at most, thereby wherein 10 bits of 11 bits in the resource allocation territory are used in the base station, such as minimum 10 bits (promptly removing 10 bits of residue outside the highest-order bit), indicate corresponding 10 basic allocation units whether to be instructed to the form of bitmap.

When the number of sub-bands of system was 6, the base station can use different basic allocation unit to indicate.For example several bits can be got in the base station in the resource allocation territory, such as only getting most significant bit, as designator, be used to indicate the quantity of the included CLRU of basic allocation unit, carry out the resource indication with remaining bit then, for example most significant bit is got as indication in the base station in the resource allocation territory, as most significant bit b ₁₀When being 0 (perhaps being 1), the expression base station with 4 continuous CLRU as basic allocation unit.At this moment, minimum 6 bits in 10 remaining bits except that most significant bit are used in the base station, with the mode of bitmap come in the indication mechanism 6 basic allocation unit which be assigned with, and work as most significant bit b ₁₀When being 1 (perhaps should be 0 mutually), the expression base station with 2 continuous CLRU as basic allocation unit.At this moment, 10 the remaining bit (b except that most significant bit are used in the base station ₉～b ₀) carry out resource indication, exist 12 basic allocation unit in the system this moment, thus the base station is divided into the grouping of two overlappings with these 12 basic allocation unit, and it (is CLRU that the first grouping G1 contains 9 basic allocation unit ₀～CLRU ₁₇), and the second grouping G2 also to contain 9 basic allocation unit (be CLRU ₆～CLRU ₂₃), b is used in the base station ₉Further which resource grouping is the resource of the current distribution of indication drop in, if drop among the G1, and b then ₉Put 0, otherwise b ₉Put 1, use b then ₈～b ₀These 9 bits indicate with the form of bitmap which basic allocation unit has been instructed in the corresponding grouping.

For example, 6 subbands are arranged in the system, and this moment the base station with 2 continuous CLRU as basic allocation unit, b so ₁₀=1, when distributing 6 CLRU to the user, and that distribute is CLRU[0,1], CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1, so with b as can be known ₉Put 0, be used for indicating current distribution CLRU entirely at G1.Since CLRU[0,1] be assigned with, thus b0=1, because CLRU[2,3] be assigned with, thus b1=1, because CLRU[8,9] be assigned with, thereby b4=1, all the other bits are 0, so 0b10000010011 can be shown to be in whole RA (Resource Allocation, resource allocation) territory.

Embodiment 19:

In the present embodiment, suppose to have a 10MHz system (this system use 1024 FFT), because 10MHz one has 48 PRU, so the subband that can to generate 12 at most be group with 4 CLRU.The continuous CLRU of per four logics forms a subband (Subband).On the whole like this bandwidth, at most only have 12 subbands altogether.According to present embodiment, can in the resource allocation territory, use one or more bits to indicate the number of the CLRU that a basic allocation unit comprises.

Give (Continus Logical ResourceUnit for unicast user distribution CLRU in the base station, the continuous resource unit) time, the base station can be according to the number of sub-bands that exists in the system, different basic allocation unit is set, thereby can uses resource allocation territory to carry out the resource indication with different bit numbers.

For example, suppose that base station system uses 11 bits to indicate altogether in the resource allocation territory, when the number of sub-bands that exists in the system was 10 or 11, resource allocation and indication can be carried out with 4 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, have only 10 or 11 basic allocation unit (every unit contains 4 continuous CLRU) so in the system at most, whether thereby 11 bits in the resource allocation territory are used in the base station, indicate corresponding 10 or 11 basic allocation units to be instructed to the form of bitmap.

In the time of no more than 5 of the number of sub-bands of system, resource allocation and indication can be carried out with 2 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, have only 10 basic allocation unit (every unit contains 2 continuous CLRU) so in the system at most, thereby wherein 10 bits of 11 bits in the resource allocation territory are used in the base station, such as minimum 10 bits (promptly removing 10 bits of residue outside the highest-order bit), indicate corresponding 10 basic allocation units whether to be instructed to the form of bitmap.

When the number of sub-bands of system 6 between 9 in, the base station can use different basic allocation unit to indicate.For example one or more bits can be got in the base station in the resource allocation territory, as designator, are used to indicate the quantity of the included CLRU of basic allocation unit, carry out the resource indication with remaining bit then.For example, being 6 with the number of sub-bands that exists in the system is example, and most significant bit is got as indication in the base station in the resource allocation territory, as most significant bit b ₁₀Be 0 o'clock, the expression base station with 4 continuous CLRU as basic allocation unit.At this moment, minimum 6 bits in 10 bits that are left except that most significant bit are used in the base station, with the mode of bitmap come in the indication mechanism 6 basic allocation unit which be assigned with.As most significant bit b ₁₀Be 1 o'clock, the expression base station as basic allocation unit, is an example there to be 6 subbands in the system with 2 continuous CLRU, and is corresponding, has 12 basic allocation unit in the system.At this moment, 10 the remaining bit (b except that most significant bit are used in the base station ₉～b ₀) carry out resource indication, thus the base station be the grouping that several (such as two) overlap or do not overlap with these 12 dividing elements, and for example first divides into groups that to contain 9 basic allocation unit (be CLRU to G1 ₀～CLRU ₁₇), and the second grouping G2 also to contain 9 basic allocation unit (be CLRU ₆～CLRU ₂₃), b is used in the base station ₉Further which resource grouping is the current Resources allocation of indication drop in, if drop among the G1, and b then ₉Put 0, otherwise b ₉Put 1.Then, use b ₈～b ₀These 9 bits indicate with the form of bitmap which allocation units has been instructed in the corresponding grouping.

For example, 7 subbands are arranged in the system, and this moment the base station with 2 continuous CLRU as basic allocation unit, b so ₁₀=1.When distributing 6 CLRU to the user, and that distribute is CLRU[0,1], CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1 as can be known, used b so ₉Put 0, be used for indicating current distribution CLRU entirely at G1.Since CLRU[0,1] be assigned with, thus b0=1, because CLRU[2,3] be assigned with, thus b1=1, because CLRU[8,9] be assigned with, thereby b4=1, all the other bits are 0, so 0b10000010011 can be shown to be in whole RA (Resource Allocation, resource allocation) territory.

Embodiment 20:

In the present embodiment, suppose to have a 20MHz system (this system use 2048 FFT), because 20MHz one has 96 PRU, so the subband that can to generate 24 at most be group with 4 CLRU.The continuous CLRU of per four logics forms a subband (Subband).On the whole like this bandwidth, at most only have 24 subbands altogether.According to present embodiment, can in the resource allocation territory, use one or more bits to indicate the number of the CLRU that a basic allocation unit comprises.

Give (Continus Logical ResourceUnit for unicast user distribution CLRU in the base station, the continuous logic Resource Unit) time, the base station can be according to the number of sub-bands that exists in the system, different basic allocation unit is set, thereby can uses resource allocation territory to carry out the resource indication with different bit numbers.

For example, use 11 bits altogether when base station system in the resource allocation territory and indicate, simultaneity factor can use two resources indication territories (22 bits altogether) in the AMAP-IE message to indicate when Resources allocation each time.

When system can utilize other information field to distinguish corresponding IE message in A-MAP-IE to belong to which sub-distribution of which terminal use, then can not need in first IE, utilize partial bit to indicate the ownership of follow-up IE, can save this part bit like this to be used for indication.In the present embodiment, suppose that system can utilize other information field to distinguish which sub-distribution which terminal use corresponding IE belongs in A-MAP-IE.

When the number of sub-bands of system was 21 or 22, resource allocation and indication can be carried out with 4 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, have only 21 or 22 basic allocation unit (every unit contains 4 continuous CLRU) so in the system at most, whether thereby totally 22 bits are used in 2 resource allocation territories in the base station, indicate corresponding 21 or 22 basic allocation units to be instructed to the form of bitmap.

In the time of no more than 11 of the number of sub-bands of system, resource allocation and indication can be carried out with 2 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, have only 22 basic allocation unit (every unit contains 2 continuous CLRU) so in the system at most, whether thereby totally 22 bits in 2 resource allocation territories are used in the base station, indicate corresponding 22 basic allocation units to be instructed to the form of bitmap.

When the number of sub-bands of system 12 between 20 in, the base station can use different basic allocation unit to indicate.For example one or more bits can be got in the base station in the resource allocation territory, as designator, are used to indicate the quantity of the included CLRU of basic allocation unit, carry out the resource indication with remaining bit then.For example, most significant bit is got as indication in the base station in the resource allocation territory, as most significant bit b ₁₀Be 0 o'clock, the expression base station with 4 continuous CLRU as basic allocation unit.At this moment, with the sub band number that exists in the system is 12 to be example, have 12 basic allocation unit in the system, and minimum 12 bits in 21 remaining bits of base station use except that most significant bit, with the mode of bitmap come in the indication mechanism 12 basic allocation unit which be assigned with, as most significant bit b ₁₀It is 1 o'clock, the expression base station with 2 continuous CLRU as basic allocation unit, at this moment, with the sub band number that exists in the system is 12 to be example, have 24 basic allocation unit in the system, and the base station uses 21 the remaining bits except that most significant bit to carry out the resource indication, and further, the base station is divided into the grouping that several (such as two) overlap or do not overlap with these 24 basic allocation unit.For example to contain 20 basic allocation unit (be CLRU to the first grouping G1 ₀～CLRU ₃₉), and the second grouping G2 also to contain 20 unit (be CLRU ₈～CLRU ₄₇, perhaps CLRU ₁₂～CLRU ₅₁, perhaps CLRU ₁₆～CLRU ₅₅..., perhaps CLRU ₄₀～CLRU ₇₉), the base station uses the most significant bit in 21 remaining bits further to indicate current Resources allocation to drop in which resource grouping, if drop among the G1, then this bit puts 0, otherwise this bit puts 1, indicates with the form of bitmap with 20 minimum bits then which allocation units has been instructed in the corresponding grouping.

For example, 12 subbands are arranged in the system, and this moment, the base station was as basic allocation unit with 2 continuous CLRU, so this moment the higher bit b10=1 in first RA territory, partial bit is got in the base station from first RA territory, such as second high order bit, be used to indicate the grouping of resource to be allocated to be subordinate to situation, again according to the bit of certain specific order to being left, carry out assignment such as 20 remaining bits, for example the base station with the significant bits in second RA territory as the significant bits in the resource allocation bit, and with the most significant bit of the 3rd high order bit in first RA territory (first and second high order bits have been used for indicating basic allocation unit and group) as resource allocation bit, the resource of little logical number is corresponding to low-order bit.When distribute 6 (continuous in twos) CLRU to the user, and that distribute is CLRU[0,1], CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1 as can be known, used the b9 in first RA territory to put 0 so, be used for indicating current distribution CLRU entirely at G1, because CLRU[0,1] be assigned with, thus the b0=1 in the RA territory among second IE, because CLRU[2,3] be assigned with, thus the b 1=1 in the RA territory among second IE, because CLRU[8,9] be assigned with, thereby the b4=1 in the RA territory among second IE, all the other bits are 0, so first RA (ResourceAllocation, resource allocation) 0b10000000000 can be shown to be in the territory, and 0b00000010011 can be shown to be in second RA territory.

Embodiment 21:

In the present embodiment, suppose to have a 5MHz system (this system uses 512 FFT), because 5MHz one has 24 PRU, each PRU is corresponding to a CLRU.Basic allocation unit can comprise a plurality of mark logical resources unit, and here, mark logical resource unit can be several CLRU of branch.For example, mark logical resource unit can be MLRU (Minimum A-MAP Logical Resource Unit, minimum A-MAP logical resource unit), wherein, a MLRU is equivalent to 1/2 CLRU, therefore, can form maximum 48 MLRU on the whole bandwidth in a subframe.It will be appreciated by persons skilled in the art that mark logical resource unit comprises that 1/2 CLRU is an example, the present invention is not limited only to this, for example, and corresponding 1/4 CLRU of mark logical resource unit further.

The base station give distribute MLRU for unicast user in, the base station can be used different basic allocation unit to carry out resource and indicate according to altogether the number of MLRU in the system.

For example, in the resource allocation territory, use 11 bits altogether when base station system and indicate, when the number of the MLRU of system is 40 or 44, the base station can 4 MLRU as a basic allocation unit, carry out resource allocation and indication.Owing in a basic allocation unit 4 MLRU are arranged, have only 10 or 11 basic allocation unit (every unit contains 4 continuous N LRU) so in the system at most, whether thereby 11 bits in the resource allocation territory are used in the base station, indicate corresponding 10 or 11 basic allocation units to be instructed to the form of bitmap.

And in the time of no more than 22 of the MLRU number of system, resource allocation and indication can be carried out with 2 MLRU as basic allocation unit in the base station.Owing in a basic allocation unit 2 MLRU are arranged, have only 11 basic allocation unit (every unit contains 2 MLRU) so in the system at most, thereby 11 bits indicate corresponding 10 basic allocation units whether to be instructed to the form of bitmap in the use resource allocation territory, base station.

When the MLRU of system number 24 between 36 in, the base station can use different basic allocation unit to indicate.For example one or more bits can be got in the base station in the resource allocation territory, as designator, be used to indicate the quantity of the included MLRU of basic allocation unit, carry out the resource indication with remaining bit then, for example most significant bit is got as indication in the base station in the resource allocation territory.For example, being 24 with the MLRU number that exists in the system is example, as most significant bit b ₁₀Be 0 o'clock, the expression base station with 4 continuous MLRU as basic allocation unit.At this moment, minimum 6 bits in 10 bits that are left except that most significant bit are used in the base station, with the mode of bitmap come in the indication mechanism 6 basic allocation unit which be assigned with.As most significant bit b ₁₀Be 1 o'clock, as basic allocation unit, at this moment, 10 the remaining bit (b except that most significant bit are used in the base station with 2 continuous MLRU in the expression base station ₉～b ₀) carry out resource indication, exist 12 basic allocation unit in the system this moment, thus the base station is divided into the grouping that several (such as two) overlap or do not overlap with these 12 basic allocation unit, and for example to contain 9 unit (be MLRU to the first grouping G1 ₀～MLRU ₁₇), and the second grouping G2 also to contain 9 unit (be MLRU ₆～MLRU ₂₃, perhaps MLRU ₁₀～MLRU ₂₇, perhaps MLRU ₁₄～MLRU ₃₁, perhaps MLRU ₁₈～MLRU ₃₅), b is used in the base station ₉Further which resource grouping is the current Resources allocation of indication drop in, if drop among the G1, and b then ₉Put 0, otherwise b ₉Put 1, use b then ₈～b ₀These 9 bits indicate with the form of bitmap which basic allocation unit has been instructed in the corresponding grouping.

For example, 28 MLRU are arranged in the system, and this moment the base station with 2 continuous N LRU as basic allocation unit, b so ₁₀=1, when distributing 6 CLRU to the user, and that distribute is CLRU[0,1], CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1 as can be known, used b so ₉Put 0, be used for indicating current distribution CLRU, because CLRU[0 entirely at G1,1] be assigned with, thus b0=1, because CLRU[2,3] be assigned with, thereby b1=1, because CLRU[8,9] be assigned with, thereby b4=1, all the other bits are 0, so 0b10000010011 can be shown to be in whole RA (Resource Allocation, resource allocation) territory.

Embodiment 22:

In the present embodiment, suppose to have a 20MHz system (this system use 2048 FFT), because 20MHz one has 96 PRU, so the subband that can to generate 24 at most be group with 4 CLRU.The continuous CLRU of per four logics forms a subband (Subband).On the whole like this bandwidth, at most only have 24 subbands altogether.According to present embodiment, can in the resource allocation territory, use one or more bits to indicate different distribution methods and partition size.

Give in the base station for the unicast user distribution based on CLRU (Continus LogicalResource Unit, the continuous logic Resource Unit) time, the base station can be according to number and the system bandwidth situation based on the continuous logic Resource Unit of subband that exist in the system, varigrained basic allocation unit is set, and what exist in the system all is known based on the number of the continuous logic Resource Unit of subband and system bandwidth situation base station and terminal, base station and terminal all can according to exist in the system based on the number of the continuous logic Resource Unit of subband and the size that system bandwidth is judged current basic allocation unit, thereby can use resource allocation territory to carry out the resource indication with different bit numbers

When system can utilize other information field to distinguish corresponding IE message in A-MAP-IE message to belong to which sub-distribution of which terminal use, then can not need in first A-MAP-IE message, utilize partial bit to indicate the ownership of follow-up A-MAP-IE message, can save this part bit like this to be used for indication.In the present embodiment, suppose that system can utilize other information field to distinguish which sub-distribution which terminal use is corresponding A-MAP-IE message belong in A-MAP-IE message.

When the number of sub-bands of system was 23 or 24, resource allocation and indication can be carried out with 4 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, 23 or 24 basic allocation unit (every unit contains 4 continuous CLRU) are arranged in the system so, whether thereby totally 22 bits are used in 2 resource allocation territories in the base station, indicate corresponding 21 or 22 basic allocation units to be instructed to the form of bitmap.This moment because the bit number of bitmap less than corresponding basic allocation unit number, so in order to guarantee that two last basic allocation unit can be instructed to, employing different bit in allocation domain is indicated the different method of granularity, preceding 21 bits, granularity is that 1 basic allocation unit (is the b0 bit corresponding subband 0 in first RA territory, b1 bit corresponding subband 1 in first RA territory, b 10 bit corresponding subband 10 in first RA territory, b0 bit corresponding subband 11...... in second RA territory, b9 bit corresponding subband 20 in second RA territory), corresponding 3 basic allocation unit of last bit (i.e. b10 bit corresponding subband 21,22,23 in second RA territory), if the b10 bit in second RA territory is put 1, so corresponding three basic allocation unit (subband 21,22,23) are assigned with.In actual use, subband 21,22,23 general tied distribution.

Embodiment 23:

In the present embodiment, suppose to have a 20MHz system (this system use 2048 FFT), because 20MHz one has 96 PRU, so the subband that can to generate 24 at most be group with 4 CLRU.The continuous CLRU of per four logics forms a subband (Subband).On the whole like this bandwidth, at most only have 24 subbands altogether.Give in the base station for the unicast user distribution based on CLRU (Continus Logical Resource Unit, the continuous logic Resource Unit) time, the base station can be according to number of sub-bands that exists in the system and system bandwidth situation, varigrained basic allocation unit is set, and what exist in the system all is known based on the number of the continuous logic Resource Unit of subband and system bandwidth situation base station and terminal, base station and terminal all can according to exist in the system based on the number of the continuous logic Resource Unit of subband and the size that system bandwidth is judged current basic allocation unit, thereby can use resource allocation territory to carry out the resource indication with different bit numbers.

System carried out logical number to all LRU before LRU is divided into a plurality of basic allocation unit, shown in following step: at first, continuous logic Resource Unit in each frequency partition is carried out the logical number first time according to a particular order (such as natural ascending order), then the distributed logic Resource Unit in each frequency partition is carried out the logical number second time according to a particular order (such as natural ascending order), wherein, first numbering in the logical number second time is arranged in after last numbering of the logical number first time.

For example, suppose that FPCT is the frequency partition number, S _{CLRU, i}Be 0,1 ..., all CLRU number in the i frequency partition, L _{CLRU, FPm}Be the number of m the CLRU in the frequency partition, S then _{CLRU, i}With L _{CLRU, FPm}Relation as shown in Equation 1:

S_{CLRU, i} = Σ_{m = 0}^{m = i} L_{CLRU, FPm},

0≤i≤FPCT-1 (formula 1)

Can pass through formula 2 pairs the 0th, 1 ..., i frequency partition CLRU altogether renumbers, here CLRU _FPi[m] expression frequency partition FP _iIn m CLRU

CLRU[j]=CLRU _FPi[j-S _{CLRU, i-1}], S _{CLRU, i-1}≤ j＜S _{CLRU, i}), 0≤i≤FPCT-1 (formula 2)

Suppose S _{DLRU, i}Be the 0th, 1 ..., all DLRU numbers in i the frequency partition, L _{DLRU, FPm}Be m the DLRU number in the frequency partition, then S _{DLRU, i}With L _DLRU, _FPmRelation as shown in Equation 3:

S_{DRU, i} = Σ_{m = 0}^{m = i} L_{DRU, FPm},

0≤i≤FPCT-1 (formula 3)

Can be by 4 pairs the 0th, 1 of following formula ..., all DLRU in i frequency partition renumber, here DLRU _FPi[m] expression frequency partition FP _iIn m DLRU.

(formula 4)

DLRU[j]＝DLRU _FPi[j-S _DLRU，i-1]，S _DLRU，i-1≤j＜S _DLRU，i)，0≤i≤FPCT-1

Then, can be arranged in the DLRU in all frequency partition the CLRU in all frequency partition, the numbering of all LRU after arranging as shown in Equation 5:

(formula 5)

LRU [k] = \{\begin{matrix} CLRU [k], & 0 \leq k < S_{CLRU, FPCT - 1} \\ DLRU [k - S_{CLRU, FPCT - 1}], & S_{CLRU, FPCT - 1} \leq k < S_{CLRU, FPCT - 1} + S_{DLRU, FPCT - 1} \end{matrix}\}

Here,

0 \leq k < Σ_{m = 0}^{m = FPCT - 1} {FPS}_{m}

For example, have 4 frequency partition in the system, i.e. frequency partition number FPCT=4,24 PLRU are respectively arranged in each frequency partition, and wherein, first frequency partition has 4 CLRU, 20 DLRU, second frequency partition has 8 CLRU, 16 DLRU, and the 3rd frequency partition has 12 CLRU, 12 DLRU, the 4th frequency partition has 16 CLRU, 8 DLRU, and the base station at first renumbers the CLRU in each frequency partition according to the order of frequency partition so, 4 CLRU of first frequency partition are numbered LRU[0], LRU[1], LRU[2], LRU[3], 8 CLRU of second frequency partition are numbered LRU[4], LRU[5] ..., LRU[11], 12 CLRU of the 3rd frequency partition are numbered LRU[12], LRU[13] ..., LRU[23], 16 CLRU of the 4th frequency partition are numbered LRU[24], LRU[25] ..., LRU[39].

Subsequently, the base station renumbers the DLRU in each frequency partition according to the order of frequency partition, and numbering is arranged in the back of CLRU numbering, 20 DLRU of first frequency partition is numbered LRU[40], LRU[41], ..., LRU[59], 16 DLRU of second frequency partition are numbered LRU[60], LRU[61], ..., LRU[75], 12 DLRU of the 3rd frequency partition are numbered LRU[76], LRU[77], ..., LRU[87], 8 DLRU of the 4th frequency partition are numbered LRU[88], LRU[89], ..., LRU[95].

To when distributing based on CLRU for unicast user, the base station can be provided with different basic allocation unit according to the number of sub-bands that exists in the system, thereby can use the resource allocation territory with different bit numbers to carry out the resource indication in the base station.

Under the situation of above-mentioned example, using 11 bits altogether when base station system in the resource allocation territory indicates, simultaneity factor is when Resources allocation each time, because current one has 40 PRU Resource Units based on CLRU, so the indication of the resource in using 1 AMAP-IE message territory (11 bits altogether) can use the distribution indicating means as basic allocation unit with 4 CLRU when indicating, with minimum 10 the bit b0 in the RA territory, b1, ..., b9 indicates corresponding basic allocation unit { LRU respectively _[0]～LRU _[3], { LRU _[4]～LRU _[7]..., { LRU _[36]～LRU _[39], obviously the size of a basic allocation unit is exactly a subband at this moment.If basic allocation unit { LRU _[0]～LRU _[3]Be assigned with, if b0=1 so, otherwise b0=0 are basic allocation unit { LRU _[4]～LRU _[7]Be assigned with, b1=1 so, otherwise b1=0, the rest may be inferred.

When the CLRU of system number was variable, when being 23 or 24 when the number of sub-bands of system, resource allocation and indication can be carried out with 4 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, 23 or 24 basic allocation unit (every unit contains 4 continuous CLRU) are arranged in the system so, whether thereby totally 22 bits are used in 2 resource allocation territories in the base station, indicate corresponding 21 or 22 basic allocation units to be instructed to the form of bitmap.This moment because the bit number of bitmap less than corresponding basic allocation unit number, so in order to guarantee that two last basic allocation unit can be instructed to, employing different bit in allocation domain is indicated the different method of granularity, preceding 21 bits, granularity is that 1 basic allocation unit (is the b0 bit corresponding subband 0 in first RA territory, b1 bit corresponding subband 1 in first RA territory, b10 bit corresponding subband 10 in first RA territory, b0 bit corresponding subband 11...... in second RA territory, b9 bit corresponding subband 20 in second RA territory), corresponding 3 basic allocation unit of last bit (i.e. b10 bit corresponding subband 21,22,23 in second RA territory), if the b10 bit in second RA territory is put 1, so corresponding three basic allocation unit (subband 21,22,23) are assigned with.In actual conditions, subband 21,22,23 general tied distribution.

For example, 12 subbands are arranged in the system, and this moment, the base station was as basic allocation unit with 2 continuous CLRU, so this moment the higher bit b10=1 in first RA territory, partial bit is got in the base station from first RA territory, such as second high order bit, be used to indicate the grouping of resource to be allocated to be subordinate to situation, again according to the bit of certain specific order to being left, carry out assignment such as 20 remaining bits, for example the base station with the significant bits in second RA territory as the significant bits in the resource allocation bit, and with the 3rd high order bit in first RA territory (first, two high order bits have been used for indicating basic allocation unit and group) as the most significant bit of resource allocation bit, the resource of little logical number is corresponding to low-order bit.When distributing 6 (continuous in twos) CLRU to the user, and that distribute is CLRU[0,1] and, CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1 as can be known, used the b9 in first RA territory to put 0 so, were used for indicating current distribution CLRU entirely at G1; Because CLRU[0,1] be assigned with, thus the b0=1 in the RA territory among second IE; Because CLRU[2,3] be assigned with, thus the b1=1 in the RA territory among second IE; Because CLRU[8,9] be assigned with, thus the b4=1 in the RA territory among second IE, and all the other bits are 0.So first RA (Resource Allocation, resource allocation) can show to be 0b10000000000 in the territory, 0b00000010011 can be shown to be in second RA territory.

Embodiment 24

In the present embodiment, suppose to have a 5MHz system (this system uses 512 FFT), 4 frequency partition are wherein arranged, that is, and FP ₀, FP ₁, FP ₂, FP ₃, each frequency partition has 12,4,4,4 LRU respectively, wherein, 12,4,0,0 CLRU is arranged respectively among the LRU of each frequency partition, also comprises 4 DLRU in the 3rd frequency partition, also comprises 4 DLRU in the 4th frequency partition.

For example, suppose that FPCT is the frequency partition number, S _{CLRU, i}Be 0,1 ..., all CLRU number in the i frequency partition, L _{CLRU, FPm}Be the number of m the CLRU in the frequency partition, S then _{CLRU, i}With L _{CLRU, FPm}Relation shown in formula:

S_{CLRU, i} = Σ_{m = 0}^{m = i} L_{CLRU, FPm},

0≤i≤FPCT-1

Can pass through following formula to the 0th, 1 ..., i frequency partition CLRU altogether renumbers, here CLRU _FPi[m] expression frequency partition FP _iIn m CLRU

CLRU[j]＝CLRU _FPi[j-S _CLRU，i-1]，S _CLRU，i-1≤j＜S _CLRU，i)，0≤i≤FPCT-1

Suppose S _{DLRU, i}Be the 0th, 1 ..., all DLRU numbers in i the frequency partition, L _{DLRU, FPm}Be m the DLRU number in the frequency partition, then S _{DLRU, i}With L _DLRU, _FPmThe following formula of relation shown in:

S_{DRU, i} = Σ_{m = 0}^{m = i} L_{DRU, FPm},

0≤i≤FPCT-1

Can be by following formula to the 0th, 1 ..., all DLRU in i frequency partition renumber, here DLRU _FPi[m] expression frequency partition FP _iIn m DLRU.

Then, can be arranged in the DLRU in all frequency partition the CLRU in all frequency partition, shown in the following formula of numbering of all LRU after arranging:

LRU [k] = \{\begin{matrix} CLRU [k], & 0 \leq k < S_{CLRU, FPCT - 1} \\ DLRU [k - S_{CLRU, FPCT - 1}], & S_{CLRU, FPCT - 1} \leq k < S_{CLRU, FPCT - 1} + S_{DLRU, FPCT - 1} \end{matrix}\}

Here,

0 \leq k < Σ_{m = 0}^{m = FPCT - 1} {FPS}_{m} .

In the present embodiment, the base station at first renumbers the CLRU in each frequency partition according to the order of frequency partition, 12 CLRU of first frequency partition are numbered LRU[0], LRU[1], LRU[2], ..., LRU[11], 4 CLRU of second frequency partition are numbered LRU[12], LRU[13], ..., LRU[15].

Subsequently, the base station renumbers the DLRU in each frequency partition according to the order of frequency partition, and numbering is arranged in the back of CLRU numbering, for example, 4 DLRU of the 3rd frequency partition is numbered LRU[16], LRU[17] ..., LRU[19]; 4 DLRU of the 4th frequency partition are numbered LRU[20], LRU[21] ..., LRU[23].

Give in the base station for the unicast user distribution based on CLRU (Continus LogicalResource Unit, the continuous logic Resource Unit) time, the base station can be according to number and the system bandwidth situation based on the continuous logic Resource Unit of subband that exist in the system, varigrained basic allocation unit is set, and what exist in the system all is known based on the number of the continuous logic Resource Unit of subband and system bandwidth situation base station and terminal, base station and terminal all can be judged the size of current basic allocation unit according to number and the system bandwidth based on the continuous logic Resource Unit of subband in the system, thereby can use the resource allocation territory with different bit numbers to carry out the resource indication.In this example, distributing CLRU (Contiguous logical resource unit for unicast user, the continuous resource unit) time, because one has 16 CLRU, and resource allocation territory one has 11 bits, when using a CLRU as corresponding basic allocation unit, 16 basic allocation unit will be arranged, this moment will be above 11 indication bit, so the base station uses 2 CLRU as corresponding basic allocation unit, like this, just only need 8 indication bit just can have been indicated whole basic allocation unit.

So can be basic allocation unit with two CLRU.Contain logical number continuous two CLRU, i.e. { LRU in each unit _[0]～LRU _[1], { LRU _[2]～LRU _[3]... { LRU _[14]～LRU _[15]8 unit altogether.Obviously the size of a basic allocation unit is exactly 1/2nd height bands at this moment.

In RA (Resource Allocation, resource allocation) territory, have 11 bits, (for example, b ₁₀, b ₉..., b ₀) in 8 bit (for example, b ₇..., b ₀) be used for indicating 8 which basic allocation unit of basic allocation unit (or claiming subband) to be assigned with, for example, if { LRU _[0]～LRU _[1]Be assigned with b so ₀=1, otherwise b ₀=0, if { LRU _[2]～LRU _[3]Be assigned with b so ₁=1, otherwise b ₁=0, by that analogy, if { LRU _[14]～LRU _[15]Be assigned with b so ₇=1, otherwise b ₇=0, remaining 3 bit b ₁₀, b ₉, b ₈Put 0.

Embodiment 25:

System carried out logical number to all LRU before LRU is divided into a plurality of basic allocation unit, shown in following step: at first, each subband continuous logic Resource Unit in each frequency partition is carried out the logical number first time according to a particular order (such as natural ascending order).Then, little band (miniband) logical resource unit in each frequency partition is carried out the logical number second time according to a particular order (such as natural ascending order), wherein, first numbering in the logical number second time is arranged in after last numbering of the logical number first time.Then, distributed logic Resource Unit in each frequency partition is carried out logical number for the third time according to a particular order (such as natural ascending order), wherein, first numbering in the logical number is arranged in after last numbering of logical number for the second time for the third time.

For example have 4 frequency partition in the system, promptly frequency partition number FPCT=4 respectively has 24 PRU in each frequency partition, and wherein, first frequency partition has 4 subband CLRU, 4 little band CLRU, 16 DLRU; Second frequency partition has 8 subband CLRU, 4 little band CLRU, 12 DLRU; The 3rd frequency partition has 12 subband CLRU, 4 little band CLRU, 8 DLRU; The 4th frequency partition has 16 CLRU, 4 little band CLRU, 4 DLRU.At first, the base station renumbers the subband CLRU in each frequency partition according to the order of frequency partition, 4 subband CLRU of first frequency partition are numbered LRU[0], LRU[1], LRU[2], LRU[3], 8 subband CLRU of second frequency partition are numbered LRU[4], LRU[5] ..., LRU[11], 12 subband CLRU of the 3rd frequency partition are numbered LRU[12], LRU[13] ..., LRU[23], 16 subband CLRU of the 4th frequency partition are numbered LRU[24], LRU[25] ..., LRU[39].

Subsequently, the base station renumbers the little band CLRU in each frequency partition according to the order of frequency partition, and numbering is arranged in the back that subband CLRU numbers, for example, 4 little band CLRU of first frequency partition are numbered LRU[40], LRU[41] ..., LRU[43], 4 little band CLRU of second frequency partition are numbered LRU[44], LRU[45] ..., LRU[47], 4 little band CLRU of the 3rd frequency partition are numbered LRU[48], LRU[49] ..., LRU[51], 4 little band CLRU of the 4th frequency partition are numbered LRU[52], LRU[53] ..., LRU[55].

Then, the base station renumbers the DLRU in each frequency partition according to the order of frequency partition, and numbering is arranged in the back that little band CLRU numbers, for example, 16 DLRU of first frequency partition are numbered LRU[56], LRU[57] ..., LRU[71], 12 DLRU of second frequency partition are numbered LRU[72], LRU[73] ..., LRU[83], 8 DLRU of the 3rd frequency partition are numbered LRU[84], LRU[85] ..., LRU[91], 4 DLRU of the 4th frequency partition are numbered LRU[92], LRU[93] ..., LRU[95].

Give in the base station for the unicast user distribution based on CLRU (Continus LogicalResource Unit, the continuous logic Resource Unit) time, the base station can be according to number and the system bandwidth situation based on the continuous logic Resource Unit of subband that exist in the system, varigrained basic allocation unit is set, and all be known based on the number of the continuous logic Resource Unit of subband and system bandwidth situation base station and terminal in the system, base station and terminal all can be judged the size of current basic allocation unit according to number and the system bandwidth based on the continuous logic Resource Unit of subband in the system, thereby can use the resource allocation territory with different bit numbers to carry out the resource indication.

Using 11 bits altogether when base station system in the resource allocation territory indicates, simultaneity factor is when Resources allocation each time, because current one has 40 PRU Resource Units based on subband CLRU, so the indication of the resource in using 1 AMAP-IE message territory (11 bits altogether) are when indicating, if use 2 CLRU as basic allocation unit, 20 basic allocation unit will appear so, greater than 11 bits, so can use the distribution indicating means as basic allocation unit with 4 CLRU this moment, with minimum 10 the bit b0 in the RA territory, b1 ..., b9 indicates corresponding basic allocation unit { LRU respectively _[0]～LRU _[3], { LRU _[4]～LRU _[7]..., { LRU _[36]～LRU _[39].If basic allocation unit { LRU _[0]～LRU _[3]Be assigned with, if b0=1 so, otherwise b0=0 are basic allocation unit { LRU _[4]～LRU _[7]Be assigned with, b1=1 so, otherwise b1=0, the rest may be inferred.

And when the CLRU number of system be not above-mentioned numerical value, but when variable, when being 23 or 24 such as the number of sub-bands when system, resource allocation and indication can be carried out with 4 continuous CLRU as basic allocation unit in the base station.Owing in a subband 4 CLRU are arranged, 23 or 24 basic allocation unit (every unit contains 4 continuous CLRU) are arranged in the system so, whether thereby totally 22 bits are used in 2 resource allocation territories in the base station, indicate corresponding 21 or 22 basic allocation units to be instructed to the form of bitmap.This moment because the bit number of bitmap less than corresponding basic allocation unit number, so in order to guarantee that two last basic allocation unit can be instructed to, employing different bit in allocation domain is indicated the different method of granularity, preceding 21 bits, granularity is that 1 basic allocation unit (is the b0 bit corresponding subband 0 in first RA territory, b1 bit corresponding subband 1 in first RA territory, b10 bit corresponding subband 10 in first RA territory, b0 bit corresponding subband 11...... in second RA territory, b9 bit corresponding subband 20 in second RA territory), corresponding 3 basic allocation unit of last bit (i.e. b10 bit corresponding subband 21,22,23 in second RA territory), if the b10 bit in second RA territory is put 1, so corresponding three basic allocation unit (subband 21,22,23) are assigned with.Under actual conditions, subband 21,22,23 general tied distribution.

For example, 12 subbands are arranged in the system, and this moment, the base station was as basic allocation unit with 2 continuous CLRU, so this moment the higher bit b10=1 in first RA territory, partial bit is got in the base station from first RA territory, such as second high order bit, be used to indicate the grouping of resource to be allocated to be subordinate to situation, again according to the bit of certain specific order to being left, carry out assignment such as 20 remaining bits, for example the base station with the significant bits in second RA territory as the significant bits in the resource allocation bit, and with the 3rd high order bit in first RA territory (first, two high order bits have been used for indicating basic allocation unit and group) as the most significant bit of resource allocation bit, the resource of little logical number is corresponding to low-order bit.When distribute 6 (continuous in twos) CLRU to the user, and that distribute is CLRU[0,1], CLRU[2,3], CLRU[8,9] time, base station this moment, these CLRU were entirely in G1 as can be known, used the b9 in first RA territory to put 0 so, be used for indicating current distribution CLRU entirely at G1, because CLRU[0,1] be assigned with, thus the b0=1 in the RA territory among second IE, because CLRU[2,3] be assigned with, thus the b1=1 in the RA territory among second IE, because CLRU[8,9] be assigned with, thereby the b4=1 in the RA territory among second IE, all the other bits are 0, so first RA (Resource Allocation, resource allocation) 0b10000000000 can be shown to be in the territory, and 0b00000010011 can be shown to be in second RA territory.
