Example 1

In this embodiment, a 20 MHz system bandwidth (100 physical resource block PRBs, that is, 25 resource block groups RBG, RBG numbers 1 to 25; P=4), and a base station allocates 3 clusters in downlink control information DCI (assuming S0) =1, S1=4, S2=12, S3=20), and the unit of the cluster is a resource block group as an example. 3 is a schematic diagram of a cluster allocated by a base station to three clusters of a user equipment according to a preferred embodiment of the present disclosure, as shown in FIG.

According to the above assumption, after receiving the DCI, the user equipment (UE) passes max(ceil(log2(N_UL_RB*(N_UL_RB+1)/2)), ceil(log2(Com(ceil(N_UL_RB/P+1), 4)))))=max(ceil(log2(100*(100+1)/2)), ceil(log2(Com(ceil(100/4+1),4))))))) 14-bit cluster The frequency resource information obtains the values of S0, S1, S2, and S3.

The frequency resource information of the cluster is represented by cluster information of four position points. The first position point S0 indicates the start position of the first cluster, the second position point S1 indicates the end position of the first cluster, and the third position point S2 indicates the start position of the second cluster, the fourth position The position point S3 represents the start position of the third cluster.

According to the above assumption, the length of the first cluster is S1 - S0 = 4-1 = 3 RBGs (equal to 3 * 4 = 12 PRBs). Each cluster is exactly the same size, and in this embodiment, it is 3 RBGs.

Cumulative value of cluster information

To express. In this embodiment,

That is, r = 14287, and expression r = 14287 requires ceil (log2 (14287)) = ceil (13.8) = 14 bits. That is, after receiving the 14 bits of r=14287 in the DCI, the UE knows the values of S0, S1, S2, and S3, so that the frequency position of the physical uplink shared channel PUSCH is known, and thus the frequency specified by the DCI. The physical uplink shared channel PUSCH is transmitted on the location (S0, S1, S2, S3).

Since the above-mentioned physical uplink shared channel PUSCH spans S0=1 to S3+(S1-S0)=20+(4-1)=23 RBGs (23*4=92 PRBs; 92*0.18=16.56MHz bandwidth) . Since 16.56MHz is greater than 20MHz*80%=16MHz, the radio regulatory requirements are met.

Example 2

Similar to Embodiment 1. The difference is that the size of the cluster is represented by Q=2 bits (the value of Q is “00”, which represents “1” in decimal). The unit of the cluster is the resource block group RBG, that is, the size of the cluster is An RBG.

For S0, S1, S2, and S3, the first position point S0 indicates the start position of the first cluster, the second position point S1 indicates the start position of the second cluster, and the third position point S2 indicates the third position. The starting position of the cluster, the fourth position point S3 indicates the starting position of the fourth cluster. This expresses 4 clusters.

The allocated bandwidth (16.56MHz) meets the radio regulatory requirements (20MHz*80%=16MHz).

Example 3

In this embodiment, the 20 MHz system bandwidth (100 physical resource blocks PRB; number 0-99), the base station allocates the starting physical resource block offset in the downlink control information DCI, and the number of the interval physical resource blocks is 10 total 10 PRBs. The unit of the cluster is a resource block, and the resource allocation information is represented by a state as an example. 4 is a schematic diagram of a plurality of clusters having allocation intervals allocated by a base station to a user equipment according to a preferred embodiment of the present disclosure, as shown in FIG.

According to the above assumption, 10 PRBs numbered 1, 11, 21, 31, 41, 51, 61, 71, 81, 91 will be allocated to the user equipment. The state used is "46" as shown in Table 1.

When the information of the resource allocation in the DCI received by the user equipment is the state "46", the user equipment transmits the physical physics at the 10 PRBs numbered 1, 11, 21, 31, 41, 51, 61, 71, 81, 91. Uplink shared channel PUSCH.

Since the above-mentioned physical uplink shared channel PUSCH spans a total of 91 PRBs (91*0.18=16.38 MHz) of PRB numbers 1 to 91, the radio control requirement (20 MHz*80%=16 MHz) is achieved.

Table 1

Example 4

In this embodiment, the 20 MHz system bandwidth (100 physical resource blocks PRB; number 0-99), the base station allocates the starting physical resource block offset in the downlink control information DCI, and the number of the interval physical resource blocks is 10 total 10 PRBs. The unit of the cluster is a resource block, and the resource allocation information is represented by a 10-bit bitmap (assuming that the value of the bitmap is "1100000000") as an example. As shown in Figure 4.

According to the above assumption, the frequency resource information of the cluster is represented by a bitmap of W=10 bits, the bit corresponding to the bitmap of W=10 bits is used to represent the physical resource block offset, and the highest bit MSB corresponds to the smallest physical resource block offset. If the bit in the bitmap is "1", it means that the physical resource block corresponding to the physical resource block offset is allocated to the user equipment, otherwise it is not allocated.

Since the value of the bitmap is "1100000000" and both the MSB and the second high bit are "1", the smallest physical resource block offset 0 and the second smallest physical resource block offset 1 are allocated to the user equipment. That is to say, 20 PRBs numbered 0, 1, 10, 11, 20, 21, 30, 31, 40, 41, 50, 51, 60, 61, 70, 71, 80, 81, 90, 91 Assigned to the user device.

When the information of the resource allocation in the DCI received by the user equipment is the bitmap “1100000000”, the user equipment is numbered 0, 1, 10, 11, 20, 21, 30, 31, 40, 41, 50, 51, The 20 PRBs of 60, 61, 70, 71, 80, 81, 90, and 91 transmit the physical uplink shared channel PUSCH.

Since the above-mentioned physical uplink shared channel PUSCH spans 92 PRBs (92*0.18=16.56 MHz) of PRB numbers 0 to 91, the radio control requirement (20 MHz*80%=16 MHz) is achieved.

Example 5

In this embodiment, the 20 MHz system bandwidth (100 physical resource blocks PRB; number 0-99) and the resource allocation of the base station in the downlink control information DCI are Y=max (ceil(log_(N_UL_RB*(N_UL_RB+1)/2)) ), ceil (log2 (Com(ceil(N_UL_RB/P+1), 4))))) bit map to represent resource allocation information (assuming the value of the bitmap is "10000000000001") and P=4 is an example . See Figure 4.

According to the above assumption, the base station and the user equipment divide the system bandwidth N_UL_RB into Y=max(ceil(log2(N_UL_RB*(N_UL_RB+1)/2)), ceil(log2(Com(ceil(N_UL_RB/P+1), 4) )))) = 14 clusters, each cluster has an average of Z = floor (N_UL_RB / Y) = 7 physical resource blocks. The cluster allocated by the base station to the user equipment is represented by a bit map of Y=14 bits. The highest bit of Y=14 bits corresponds to the last cluster. The lowest bit of Y = 14 bits corresponds to the first cluster. The first physical resource block of the first cluster corresponds to a physical resource block having the smallest physical resource block number among the N_UL_RB=100 physical resource blocks. Among them, floor () is a rounding operation. Finally N_UL_RB–Y*Z=2 physical resource blocks will be attached to the last cluster, and the last cluster has 7+(100-14*7)=9 PRBs.

The physical resource block number of the first cluster is [0,...,Z-1]*Y, ie, 0, 14, 28, 42, 56, 70, 84;

The physical resource block number of the second cluster is [0,...,Z-1]*Y+1, that is, 1, 15, 29, 43, 57, 71, 85;

Similarly, the physical resource block number of the Cth cluster is [0,...,Z-1]*Y+(C-1), that is, 1, 15, 29, 43, 57, 71, 85. Where C is the number of the cluster, 0<=C<=Y-1, and is an integer;

The physical resource block number of the 13th cluster is [0,...,Z-1]*Y+12, ie, 12, 26, 40, 54, 68, 82, 96;

The physical resource block number of the 14th cluster is [0,...,Z-1]*Y+13, ie 13,27,41,55,69,83,97,98,99 (because "the last N_UL_RB–Y *Z=2 physical resource blocks will be appended to the last cluster").

According to the above assumption, the first and last clusters are assigned to the user equipment (because the value of the bitmap is "10000000000001"). That is, 16 physical resource blocks PRBs with physical

resource block numbers

0, 13, 14, 27, 28, 41, 42, 55, 56, 69, 70, 83, 84, 97, 98, 99 are assigned to the user. device.

When the information about the resource allocation in the DCI received by the user equipment is the bitmap “10000000000001”, the user equipments are numbered 0, 13, 14, 27, 28, 41, 42, 55, 56, 69, 70, 83, 84, 97, 98, 99 These 16 PRBs transmit a physical uplink shared channel PUSCH.

Since the above-mentioned physical uplink shared channel PUSCH spans a total of 100 PRBs (100*0.18=18 MHz) of PRB numbers 0 to 99, the radio control requirement (20 MHz*80%=16 MHz) is achieved.

When the number of physical resource blocks allocated by the base station is 70 (for example, when the information of resource allocation in the DCI is bitmap "01010101101010"), the user equipment should be divided into two resource components. Shoot. The physical resource block of the two resource components is 70. In an embodiment, the user equipment may be transmitted in 64+6, 60+10, 54+16, 50+20, 45+25, 40+30. In an embodiment, each resource component transmits a different transport block. In an embodiment, each resource component transmits a different portion of the same transport block.

Example 6

In this embodiment, resource allocation information is represented by a 20 MHz system bandwidth (100 physical resource blocks PRB; number 0-99) and a resource allocation of the base station in the downlink control information DCI with a N _Cluster = 10 bit bitmap (assuming a bitmap) The value is "1000000010"), the number of physical resource blocks in a cluster that are N _Cluster clusters and one cluster

Explain the examples.

According to the above assumption, the frequency resource information includes cluster information ("1000000010") of N _Cluster = 10 bits, sharing N _Cluster clusters. Then, the base station allocates the first cluster (ID _Cluster =0) and the ninth cluster (ID _Cluster = 8).

Then, the physical resource block PRB number of the physical uplink shared channel PUSCH of the first cluster (ID _Cluster =0) is

Or n _PRB =[0,1,2,...,(floor(N_UL_RB/N _Cluster )-1)]*N _Cluster +ID _Cluster . That is, 10 PRBs with PRB numbers of 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 are allocated to the user equipment; physical uplink shared channel of the 9th cluster (ID _Cluster = 8) The physical resource block PRB number of the PUSCH is

Or n _PRB =[0,1,2,...,(floor(N_UL_RB/N _Cluster )-1)]*N _Cluster +ID _Cluster . That is, 10 PRBs with PRB numbers of 8, 18, 28, 38, 48, 58, 68, 78, 88, 98 are assigned to the user equipment. That is, the base station allocates 0, 8, 10, 18, 20, 28, 30, 38, 40, 48, 50, 58, 60, 68, 70, 78, 80, 88, 90, 98 to the user equipment. These 20 PRBs. The user equipment transmits the physical uplink shared channel PUSCH by using the 20 PRBs.

In this case, n _PRB is the physical resource block number.

Is the number of physical resource blocks in a cluster, and ID _Cluster is the number or identifier of the cluster. The highest bit MSB of the cluster information of the N _Cluster bits corresponds to the cluster having the smallest cluster number ID _Cluster . n _PRB ranges from 0 to N_UL_RB-1,

The range is 1 to N_UL_RB, and the ID _Cluster ranges from 0 to N _Cluster -1.

In this embodiment,

ID _Cluster 's range is 0 to 9.

Since the above-mentioned physical uplink shared channel PUSCH spans a total of 99 PRBs (99*0.18=17.82 MHz) of PRB numbers 0 to 98, the radio control requirement (20 MHz*80%=16 MHz) is achieved.

Example 7

This embodiment uses a 20 MHz system bandwidth (100 physical resource blocks PRB; half of the system bandwidth is 50 physical resource blocks PRB, and there are 17 resource block groups RBG in half of the system bandwidth, and the RBG number is 1–17; here H=3 corresponds to the RBG size of half of the system bandwidth; the 17th RBG has only 2 PRBs instead of 3), and the base station allocates 4 clusters in the downlink control information DCI (assuming S0=1, S1=4, S2= 12, S3 = 17), the unit of the cluster is a resource block group as an example. FIG. 5 is a schematic diagram of a cluster allocated by a base station to a user equipment according to a preferred embodiment of the present disclosure, as shown in FIG. 5.

According to the above assumption, after receiving the DCI, the UE passes ceil (log2(Com(ce_(N_UL_RB/(2*H)+1), 4))))=ceil(log2(Com(ceil(100/(2*) 3) +1), 4))) = frequency resource information of 12-bit clusters, and the values of S0, S1, S2, and S3 are obtained.

The frequency resource information of the cluster is represented by cluster information of four position points. The first position point S0 indicates the start position of the first cluster, the second position point S1 indicates the end position of the first cluster, and the third position point S2 indicates the start position of the second cluster, the fourth position The position point S3 indicates the end position of the second cluster. S0 offset system bandwidth N_UL_RB=100 half (ie, 50 PRB) representation The starting position of the third cluster, the second position point S1 offset system bandwidth N_UL_RB=100 half indicates the end position of the third cluster, and the third position point S2 offset system bandwidth N_UL_RB=100 half means The starting position of the 4 clusters, the 4th position point S3 offset system bandwidth N_UL_RB = 100 indicates the end position of the 4th cluster. That is, treating half of the system bandwidth as a "standalone" resource, allocating 2 clusters over half of the system bandwidth and then copying it to the other half of the system bandwidth (using the translation method); in one embodiment, another The resource block group RGB resource above half of the system bandwidth may also be the mirror image of the resource block group RGB resource above the first half of the system bandwidth (ie, the resource block group RGB number above the other half of the system bandwidth is 17+1-S0, 17 respectively. +1-S1, 17+1-S2, 17+1-S3. That is, the numbers of RGB are 17, 14, 6, and 1, respectively, and the RBG numbers in order are 1, 6, 14, 17).

According to the above assumption, the length of the first cluster and the third cluster are both S1 - S0 = 4-1 = 3 RBGs (equal to 3 * 3 = 9 PRBs). The length of the second cluster and the fourth cluster are both S3–S2=17–12=5 RBGs (equal to (5-1)*3+2=14 PRBs; here, because the 17th cluster has only 2 PRB, so it is not directly multiplied by the size of the RBG). A total of 2*(9+14)=46 PRBs are allocated.

Cumulative value of cluster information

To express. In this embodiment,

That is, r = 2116, and expressing r = 2116 requires ceil (log2 (2116)) = ceil (11.04) = 12 bits. That is, after receiving the 12 bits of r=2116 in the DCI, the UE knows the values of S0, S1, S2, and S3, and thus knows the frequency position of the physical uplink shared channel PUSCH, thereby specifying the frequency at the DCI. The physical uplink shared channel PUSCH is transmitted on the locations (S0, S1, S2, S3; including their translation).

In the 20MHz system, compared with the existing ceil (log2 (Com(ce_(N_UL_RB/H+1), 4))))) 14-bit resource allocation scheme, after the disclosure, Ceil(log2(Com(ceil(N_UL_RB/(2*H)+1), 4)))) = 12 bits. That is, 2 bits are saved. The 2 bits saved can be used for other purposes, for example, to express an asynchronous hybrid automatic repeat request process number (HARQprocessID).

Since the above-mentioned physical uplink shared channel PUSCH spans 17 RBGs with a total of 2 copies from S0=1 to S3=17 (a total of 2*50=100 PRBs; 100*0.18=18 MHz bandwidth). Since 18MHz is greater than 20MHz*80%=16MHz, the radio regulatory requirements are met.

Example 8

This embodiment uses a 20 MHz system bandwidth (100 physical resource blocks PRB; one tenth of the system bandwidth is 10 physical resource blocks PRB, and one tenth of the system bandwidth has 10 resource block groups RBG, and the RBG number is 1–10; where H=1 corresponds to the RBG size of one tenth of the system bandwidth. That is, one RBG contains only one PRB), and the base station allocates 10*2=20 clusters in the downlink control information DCI ( Assuming that S0=1, S1=2, S2=8, and S3=9), the unit of the cluster is a resource block group as an example.

According to the above assumption, after receiving the DCI, the UE passes ceil (log2(Com(ce_(N_UL_RB/(10*H)+1), 4))))=ceil(log2(Com(ceil(100/(10*) 1) +1), 4))) = frequency resource information of a cluster of 9 bits, and the values of S0, S1, S2, and S3 are obtained.

The frequency resource information of the cluster is represented by cluster information of four position points. The first position point S0 indicates the start position of the first cluster, the second position point S1 indicates the end position of the first cluster, and the third position point S2 indicates the start position of the second cluster, the fourth position The position point S3 indicates the end position of the second cluster. One tenth of the S0 offset system bandwidth N_UL_RB (ie, 10 PRBs) indicates the start position of the third cluster, and the second position point S1 is offset by one tenth of the system bandwidth N_UL_RB (ie, 10 PRBs) ) indicates the end position of the third cluster, and the third position point S2 is offset by one tenth of the system bandwidth N_UL_RB (ie, 10 PRBs) indicating the start position of the fourth cluster, and the fourth position point S3 is biased. Move one tenth of the system bandwidth N_UL_RB (ie, 10 PRBs) Shows the end position of the 4th cluster. When S1 is equal to S2 and S2 is equal to S3, it means that there are only 10 clusters, and S0 offset system bandwidth N_UL_RB is two tenths (ie, 20 PRBs) indicating the starting position of the fifth cluster, and the second position point S1 Two tenths of the offset system bandwidth N_UL_RB (ie, 20 PRBs) indicate the end position of the fifth cluster, and the third position point S2 offsets two tenths of the system bandwidth N_UL_RB (ie, 20 PRBs) The starting position of the sixth cluster, the fourth position point S3 offsets the system bandwidth N_UL_RB by two tenths (ie, 20 PRBs) indicating the end position of the sixth cluster. And so on, nine tenths of the S0 offset system bandwidth N_UL_RB (ie, 90 PRBs) indicate the starting position of the 19th cluster, and the second position point S1 is offset by nine tenths of the system bandwidth N_UL_RB (ie, , 90 PRBs) indicate the end position of the 19th cluster, and the 3rd position point S2 offsets the system bandwidth N_UL_RB by nine tenths (ie, 90 PRBs) indicating the starting position of the 20th cluster, the fourth The position point S3 offsets nine tenths of the system bandwidth N_UL_RB (ie, 90 PRBs) indicating the end position of the 20th cluster.

According to the above assumption, the RBG number (in this example, corresponds to PRB+1. Because the PRB number is 0-99. One-tenth of the system bandwidth RBG contains only one PRB) is 1, 8, 11, 18, 21 , 28, 31, 38, 41, 48, 51, 58, 61, 68, 71, 78, 81, 88, 91, 98 (ie, the PRB numbers are 0, 7, 10, 17, 20, 27, 30, respectively) , 37, 40, 47, 50, 57, 60, 67, 70, 77, 80, 87, 90, 97). A total of 2*10=20 PRBs are allocated.

Cumulative value of cluster information

To express. In this embodiment,

That is, r=299, expressing r=299 requires ceil(log2(299))=ceil(8.22)=9 bits. That is, after receiving the r=299 of 9 bits in the DCI, the UE knows the values of S0, S1, S2, and S3, so that the frequency position of the physical uplink shared channel PUSCH is known, and thus the frequency specified by the DCI. Position (S0, S1, S2, S3; including their translation or copy or mirror) The physical uplink shared channel PUSCH is transmitted.

In the 20MHz system, compared with the existing ceil (log2 (Com(ce_(N_UL_RB/4+1), 4))))) 14-bit resource allocation scheme, after the disclosure, it is reduced to ceil (log2(Com(ceil) (N_UL_RB/(10*1)+1), 4))) = 9 bits. That is, 5 bits are saved. The 5 bits saved can be used for other purposes, for example, to express an asynchronous HARQ processID.

Since the above-mentioned physical uplink shared channel PUSCH spans S0=1 to S3=98, a total of 98 RBs (PRB0-97; a total of 98*0.18=17.64 MHz bandwidth). Since 17.64MHz is greater than 20MHz*80%=16MHz, the radio regulatory requirements are met.

Example 9

In this embodiment, the base station indicates that the user equipment needs to transmit the sounding reference signal SRS in the last symbol of the next subframe, and the base station indicates in the downlink control information DCI that the number of symbols of the current subframe is 14 under the normal cyclic prefix and the next subframe. The number of symbols is 12 for the regular cyclic prefix as an example.

According to the above assumption, after receiving the DCI, the UE finds that the number of symbols in the current subframe is 14 under the regular cyclic prefix, and since one subframe has a maximum of 14 symbols, it is known at this time that the current subframe cannot transmit the sounding reference signal SRS.

According to the above assumption, after receiving the DCI, the UE finds that the symbol number of the next subframe is 12 under the regular cyclic prefix, and knows that the next subframe can transmit the sounding reference signal SRS.

According to the above assumption, after receiving the DCI, the UE finds that the UE needs to transmit the sounding reference signal SRS in the last symbol of the next subframe. Therefore, it is found that the UE transmits the sounding reference signal SRS in the last symbol of the next subframe.

The sounding reference signal SRS may use the frequency resource of the physical uplink shared channel PUSCH or full bandwidth transmission (greater than 80% of the system bandwidth) to meet the radio regulatory requirements.

Example 10

In this embodiment, the 20 MHz system bandwidth (100 physical resource block PRBs, ie, N_UL_RB=100, physical resource block PRB index is 0-99), and the base station allocates N _Cluster clusters in the downlink control information DCI (in this example, N _Cluster = 10) or the resource block interval of the specified cluster N _Spacing (in this example, N _Spacing = N_UL_RB/N _Cluster and N _Spacing = 10), the unit of the cluster is the resource block, and the starting physical resource block PRB of the cluster in the DCI The index is 1. The length of the cluster in the DCI is 2 PRBs as an example. It should be noted that the product of the number of clusters and the resource block interval is the system bandwidth.

According to the above assumption, after receiving the DCI, the UE obtains the cluster resource information by using the lowest ceil (log2(N_UL_RB*(N_UL_RB+1)/2))=13 bit cluster resource resource information in the resource block allocation information. The length of the physical resource block PRB index and cluster. According to the assumption, in the present embodiment, the starting physical resource block PRB index of the cluster is 1 (ie, the second PRB), and the length of the cluster in the DCI is 2 PRBs. That is to say, the physical resource block PRB index of the first cluster is 1 and 2 (continuous resource allocation).

Since the number of clusters is N _Cluster = 10 and the resource block interval of the cluster is N _Spacing = 10, the physical resource block PRB index of the second cluster is 11 and 12. And so on, the physical resource block PRB index of the third cluster is 21 and 22; until the physical resource block PRB index of the 10th cluster is 91 and 92. In this way, the physical resource block PRB indexes allocated to the UE are 1, 2, 11, 12, 21, 22, 31, 32, 41, 42, 51, 52, 61, 62, 71, 72, 81, 82. 91, 92. There are 20 physical resource blocks PRB.

That is, after receiving the 13 bits in the DCI, the UE knows the frequency position (physical resource block PRB index) of the physical uplink shared channel PUSCH, and transmits the physical uplink shared channel PUSCH at the frequency position specified by the DCI.

Since the above-mentioned physical uplink shared channel PUSCH spans PRB=1 to PRB=92, a total of 92 PRBs; 92*0.18=16.56 MHz bandwidth. Since 16.56MHz is greater than 20MHz*80%=16MHz, the radio regulatory requirements are met.

It should be noted that when the starting physical resource block PRB index of the cluster allocated by the DCI reaches or exceeds the resource block interval N _Spacing of the cluster, the physical resource block PRB needs to be reversely folded, that is, the pair (physical resource block PRB index + N _Spacing ) takes the modulus of the system bandwidth N_UL_RB. That is, mod(( n _PRB + N _Spacing ), N_UL_RB), where mod(m, n) represents an operation of a mode in which m is n, and n _PRB is an allocated PRB index in the DCI. For example, assuming that the starting physical resource block PRB index of the cluster allocated by the DCI is 83 and two physical resource blocks PRB are allocated, the starting physical resource block PRB index of the allocated cluster is 83 and 84 is the physical of the first cluster. Resource block PRB index. According to the above reasoning, 93 and 94 are the physical resource block PRB indexes of the second cluster. According to the above reasoning, 103 and 104 are physical resource block PRB indexes of the third cluster. However, since 103>N _Spacing , the physical resource block PRB index exceeding the resource block interval N _Spacing should take the modulus of the system bandwidth N_UL_RB. The result of modulo is such that 3 and 4 are the physical resource block PRB indexes of the third cluster. And so on, 13 and 14 are the physical resource block PRB indexes of the 4th cluster. Until the last cluster (the 10th cluster), 73 and 74 are the physical resource block PRB indexes of the 10th cluster. In this way, the physical resource block PRB indexes allocated to the UE are 83, 84, 93, 94, 3, 4, 13, 14, 23, 24, 33, 34, 43, 44, 53, 54, 63, 64. , 73, 74. There are 20 physical resource blocks PRB.

In addition, if the PRB index of the first cluster is restricted to not exceed N _Spacing -1, no modulo operation is required.

In addition, the number of clusters N _Cluster or the resource block interval N _{Spacing of the} cluster may be notified or configured through high layer signaling, or may be notified by physical layer signaling.
