Referring to fig. 2, fig. 2 is a flowchart of a processing method of a basic interleaving unit according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step 201, determining a dividing mode of basic interleaving unit division by the BWP according to a starting common resource block number (common resource block index) of the BWP, a size (resource block bundle size) of the basic interleaving unit, and a target starting position.

The method for processing the basic interleaving unit provided by the embodiment of the invention can be applied to network side equipment or a mobile communication terminal, is used for processing the basic interleaving unit, and particularly can control the division of the basic interleaving unit.

When the method is applied to a network side device, the network side device acquires a starting common resource block number of a BWP configured for a target mobile communication terminal and a size of a basic interleaving unit, determines a target starting position, and then can determine a division mode of basic interleaving unit division by the BWP according to the starting common resource block number of the BWP, the size of the basic interleaving unit and the target starting position, and the network side device can then use the basic interleaving unit for data transmission (including downlink transmission and uplink reception) according to resource allocation.

When the method is applied to a mobile communication terminal, the mobile communication terminal can communicate with a network-side device, obtain a starting common resource block number of a BWP currently configured by the mobile communication terminal and a size of a basic interleaving unit from the network-side device, determine a target starting position, and then determine a division manner of basic interleaving unit division by the BWP according to the starting common resource block number of the BWP, the size of the basic interleaving unit and the target starting position, and the mobile communication terminal can then use the basic interleaving unit for data transmission (including downlink transmission and uplink reception) according to resource allocation.

It should be noted that the target starting point position may be predetermined by a protocol, or may be determined by a network side device configuration, for example, the target starting point position may be directly determined by the protocol or the network side device configuration as a resource block corresponding to a starting common resource block number or a resource block corresponding to a common resource block number 0, or may be determined by determining a correspondence relationship between the starting common resource block number or the common resource block number 0 and a channel type, a VRB, and a PRB, respectively, so that the target starting point position may be determined according to the channel type, the VRB, and the PRB.

Specifically, based on the partitioning rule of the basic interleaving unit of BWP, the basic interleaving unit may be partitioned between the virtual resource block VRB domain and the physical resource transport block PRB domain. With further reference to fig. 3, after the step 201, the method further includes:

step 202, dividing the virtual resource block VRB domain and the physical resource transmission block PRB domain based on the BWP dividing mode to obtain a VRB basic interleaving unit and a PRB basic interleaving unit.

In this embodiment, the size of the basic interleave unit is equal to or larger than the size of the configured PRG. The target starting position includes a resource block corresponding to the starting common resource block number of the BWP or a resource block corresponding to the common resource block number 0 (i.e., common resource block 0). Specifically, the dividing manner includes a first dividing manner and/or a second dividing manner, and if the dividing manner is the first dividing manner, the target starting point is a resource block corresponding to a starting common resource block number of the BWP; if the division mode is a second division mode, the target starting point position is a resource block corresponding to a public resource block number 0; the PRB domain is divided into a first division mode or a second division mode, and the VRB domain is divided into a first division mode or a second division mode. In this embodiment, multiple combinations of the VRB domain and the PRB domain partitioning modes are possible, so that the partitioning modes of the VRB domain and the PRB domain can be flexibly configured according to actual situations, thereby achieving a better partitioning effect of the basic interleaving unit.

The basic interleave units formed by dividing the BWP according to different dividing methods are different, and the BWP formed by dividing is described in detail below with respect to different target starting point positions.

For example, in an embodiment, the basic interleaving unit is divided by using the resource block corresponding to the starting common resource block number of BWP as the target starting position, so as to form the pattern shown in fig. 4, where the pattern is formed by dividing the resource block by taking L ═ 2 as an example in fig. 4.

As shown in fig. 4, in the first partition method, the number of basic interleaving units partitioned for BWP is K, and the partitioning of the basic interleaving units for BWP includes:

if the remainder of dividing S by L is 0 (i.e., mod (S, L) ═ 0), the size of the nth basic interleaving unit divided for the BWP is L PRBs, the common resource block number corresponding to the nth basic interleaving unit is { S0+ (N-1) × L, S0+ (N-1) × L +1, …, S0+ N × L-1}, and the resource number in the corresponding BWP is { (N-1) × L, (N-1) × L +1, …, N × L-1 };

if the remainder of dividing S by L is not 0 (namely mod (S, L) ≠ 0), the size of the M basic interleaving unit divided for the BWP is less than or equal to L PRBs, when M < K, the common resource block number corresponding to the M basic interleaving unit is { S0+ (M-1) × L, S0+ (M-1) × L +1, …, S0+ M-1 }, and the resource number in the corresponding BWP is { (M-1) × L, (M-1) × L +1, …, M × L-1 }; the last basic interleaving unit, namely when M is K, the size of the last basic interleaving unit is smaller than L PRBs, the common resource block number corresponding to the last basic interleaving unit is { S0+ (M-1) × L, S0+ (M-1) × L +1, …, S0+ S-1}, and the resource number in the corresponding BWP is { (M-1) × L, (M-1) × L +1, …, S-1 };

wherein S is the number of PRBs occupied by the BWP, L is the size of the basic interleaving unit, N is greater than or equal to 1 and less than or equal to K, M is greater than or equal to 1 and less than or equal to K, S0 is the number of the starting common resource block of the BWP, and L, N and K are both positive integers.

In another embodiment, the basic interleaving unit is divided by using the resource block corresponding to common resource block 0 as the target starting point position, so as to form the pattern shown in fig. 5, where L ═ 2 is taken as an example in fig. 5.

As shown in fig. 5, in the second partition method, the number of basic interleaving units partitioned for BWP is K, and the partitioning of the basic interleaving units for BWP includes:

the size of a first basic interleaving unit divided for the BWP is L-mod (S0, L) PRBs, the number of a common resource block corresponding to the first basic interleaving unit is { S0, S0+1, …, S0+ L-mod (S0, L) }, and the size of a last basic interleaving unit is mod { S0+ S-1, L } PRBs; the sizes of the other basic interleaving units are L PRBs;

wherein S is the size of BWP, L is the size of basic interleaving unit, S0 is the starting common resource block number of BWP, L, N and K are positive integers.

Further, after the VRB domain is divided in the manner of fig. 4 or fig. 5, and the PRB domain is divided in the manner of fig. 4 or fig. 5, the resource numbering and resource allocation are also performed on the VRB basic interleaving unit and the PRB basic interleaving unit, and then interleaving mapping is performed. Specifically, in this embodiment, after the step 202, the method further includes:

step 203, numbering the VRB basic interleaving units and the PRB basic interleaving units respectively, and determining the column number or the row number of the row-column interleaver according to the dividing mode;

and 204, after resource allocation is performed in the VRB domain, interleaving and mapping VRB basic interleaving units to PRB basic interleaving units based on a preset rank interleaver according to the numbers of the basic interleaving units of the VRB and the PRB, wherein L is the size of the basic interleaving units.

It should be noted that there are many different mapping scenarios in the mapping process, which are described in detail below:

in the first case: and mapping between the VRB of the VRB basic interleaving unit and the PRB of the PRB basic interleaving unit in a one-to-one mapping relation according to the same sequence rule.

In the second case: for a first VRB basic interleaving unit with the length not being L, interleaving and mapping are carried out according to the basic interleaving unit with the length being L, and a corresponding first PRB basic interleaving unit after interleaving comprises a first type PRB and a second type PRB; for the second case, the transmission may be made in any of the following ways:

transmitting data on other allocated resources except the first VRB basic interleaving unit, and not transmitting data on the first VRB basic interleaving unit;

transmitting data on the first type of PRBs and not transmitting data on the second type of PRBs;

transmitting data on both the first type PRBs and the second type PRBs.

Wherein, L is the size of the basic interleaving unit; the first type PRB is a part overlapped with a PRB corresponding to interleaving and mapping of a first VRB basic interleaving unit in the first PRB basic interleaving unit, the second type PRB is a part which is not overlapped with a PRB corresponding to interleaving and mapping of the first VRB basic interleaving unit in the first PRB basic interleaving unit, the number of PRBs included in the first type PRB is equal to the number of the first VRB basic interleaving units, and the number of PRBs included in the second type PRB is obtained by subtracting the number of the first VRB basic interleaving units from L.

For a second VRB basic interleaving unit with the length of L and the resource allocation of which can not allocate all L VRBs, interleaving and mapping are carried out according to the basic interleaving unit with the length of L, and after the interleaving and mapping are carried out, a corresponding second PRB basic interleaving unit after the interleaving comprises a third type PRB and a fourth type PRB;

in the third case: for a second VRB basic interleaving unit with the length of L and the resource allocation of which can not allocate all L VRBs, interleaving and mapping are carried out according to the basic interleaving unit with the length of L, and after the interleaving and mapping are carried out, a corresponding second PRB basic interleaving unit after the interleaving comprises a third type PRB and a fourth type PRB; for the third case, the transmission may be performed in any of the following ways:

transmitting data on other allocated resources except the second VRB basic interleaving unit, and not transmitting data on the second VRB basic interleaving unit;

transmitting data on the third type PRBs and not transmitting data on the fourth type PRBs;

transmitting data on both the third type PRBs and the fourth type PRBs;

the number of PRBs included in the third type PRB is equal to the number of VRBs allocated in the second VRB basic interleaving unit, and the number of PRBs included in the fourth type PRB is obtained by subtracting the number of VRBs allocated in the second VRB basic interleaving unit from L; the third type PRB is a part of the second PRB basic interleaving unit which is overlapped with the PRB corresponding to the VRB interleaving mapping allocated by the second VRB basic interleaving unit, and the fourth type PRB is a part of the second PRB basic interleaving unit which is not overlapped with the PRB corresponding to the VRB interleaving mapping allocated by the second VRB basic interleaving unit.

In a fourth case: after resource allocation is performed, if a third VRB basic interleaving unit with the length of L is allocated, but after the third VRB basic interleaving unit is interleaved and mapped to a third PRB basic interleaving unit in the BWP, where the third PRB basic interleaving unit is smaller than L, a fourth PRB basic interleaving unit with the length of L corresponding to the third PRB basic interleaving unit includes a fifth-type PRB and a sixth-type PRB; for the fourth case, the transmission may be performed in any one of the following ways:

transmitting data on other allocated resources except the third VRB basic interleaving unit, and not transmitting data on the third VRB basic interleaving unit;

transmitting data on the fifth type PRB and not transmitting data on the sixth type PRB;

transmitting data on both the fifth type PRB and the sixth type PRB;

wherein, L is the size of the basic interleaving unit; the fifth type PRB refers to a part of a fourth PRB basic interleaving unit which is repeated with a third PRB basic interleaving unit, and the sixth type PRB refers to a part of the fourth PRB basic interleaving unit which is not repeated with the third PRB basic interleaving unit; the number of PRBs included in the fifth type PRB is equal to the number of PRBs in a third PRB basic interleaving unit, and the number of PRBs included in the sixth type PRB is obtained by subtracting the number of PRBs in the third PRB basic interleaving unit from L; the fourth PRB basic interleaved unit corresponding to the third PRB basic interleaved unit is a basic interleaved unit having a length L that is obtained by extending the third PRB basic interleaved unit in a direction other than the direction in which resources are allocated to the corresponding BWP.

In one example, after resource allocation is performed, if a fourth VRB basic interleaving unit with a length of L is allocated, but after the fourth VRB basic interleaving unit is interleaved and mapped to a fifth PRB basic interleaving unit in the BWP, where the fifth PRB basic interleaving unit is smaller than L, the fourth VRB basic interleaving unit includes a first type VRB and a second type VRB; the method comprises the following steps: the first type VRB type and the second type VRB interleaving mapping adopt different interleaving mapping rules; the first type VRB is mapped to a corresponding PRB in a corresponding PRB basic interleaving unit according to a row-column interleaver; the second type VRB adopts other rules for mapping; wherein, L is the size of the basic interleaving unit; the first type VRB refers to a part which is mapped by a fourth VRB basic interleaving unit and is overlapped with a fifth PRB basic interleaving unit, and the second type VRB refers to a part which is mapped by the fourth VRB basic interleaving unit and is not overlapped with the fifth PRB basic interleaving unit.

In the above example, the PRB resources to which the second type VRBs are mapped still lie within the configured BWP, while not colliding with the PRB resources to which any other VRB basic interleaved units are mapped.

In another example, for a scenario in which the VRB basic interleaving unit size is different from the PRB basic interleaving unit size, data is transmitted only on the first L0 ═ min (L1, L2) RBs, where L1 is the size of the VRB basic interleaving unit and L2 is the size of the PRB basic interleaving unit.

In this embodiment, the same or different division rules for the VRB domain and the PRB domain are possible, and for the convenience of understanding the present invention, the following detailed description will be made with respect to an embodiment in which the same division rules for the VRB domain and the PRB domain are possible.

In the first embodiment, as shown in fig. 6, the VRB domain and the PRB domain are divided according to the PWB division scheme (i.e., the first division scheme) shown in fig. 4. In fig. 6, there are 4 basic interleaving units divided for the VRB domain, where the first VRB basic interleaving unit includes resource block 1 and resource block 2, the second VRB basic interleaving unit includes resource block 3 and resource block 4, the third VRB basic interleaving unit includes resource block 5 and resource block 6, and the fourth VRB basic interleaving unit includes resource block 7. Meanwhile, in fig. 6, there are 4 basic interleaving units divided for PRB domains, where the first PRB basic interleaving unit includes resource block 1 and resource block 2, the second PRB basic interleaving unit includes resource block 3 and resource block 4, the third PRB basic interleaving unit includes resource block 5 and resource block 6, and the fourth PRB basic interleaving unit includes resource block 7. After the basic unit division is performed on the VRB domain and the PRB domain, the resource numbering may be performed on the VRB basic interleaving unit and the PRB basic interleaving unit, respectively. The numbering of the VRB basic interleaving unit and the PRB basic interleaving unit is not further limited herein.

VRB resource allocation can start allocating contiguous resources from any location and end at any location. As shown in fig. 6, if the resource allocation is actually performed on the second to fourth VRB basic interleaving units, the resource transmission is performed on the first PRB basic interleaving unit, the third PRB basic interleaving unit, and the fourth PRB basic interleaving unit after the interleaving mapping is correspondingly performed. And part of resource blocks (resource blocks 3) of the second VRB basic interleaving unit are mapped to the fourth PRB basic interleaving unit, and the rest of resource blocks (resource blocks 4) are mapped to resource blocks which exceed the allocated BWP, so that actual transmission is not occupied. The resource blocks of the third VRB basic interleaving unit are all mapped to the first PRB basic interleaving unit. And the resource block of the fourth VRB basic interleaving unit is mapped to a part of resource block (resource block 5) of the third PRB basic interleaving unit, and the rest of resource block (resource block 6) of the third PRB basic interleaving unit is not occupied in actual transmission. In addition, the resource block 6 of the second PRB basic interleaved unit is not mapped and is not occupied in the actual transmission.

In the second embodiment, as shown in fig. 7, the VRB domain and the PRB domain are divided according to the PWB division scheme (i.e., the first division scheme) shown in fig. 4. In fig. 6, there are 4 basic interleaving units divided for the VRB domain, where the first VRB basic interleaving unit includes resource block 1, the second VRB basic interleaving unit includes resource block 2 and resource block 3, the third VRB basic interleaving unit includes resource block 4 and resource block 5, and the fourth VRB basic interleaving unit includes resource block 6 and resource block 7. Meanwhile, in fig. 7, 4 basic interleaving units are divided for PRB domains, where the first PRB basic interleaving unit includes resource block 1, the second PRB basic interleaving unit includes resource block 2 and resource block 3, the third PRB basic interleaving unit includes resource block 4 and resource block 5, and the fourth PRB basic interleaving unit includes resource block 6 and resource block 7. After the basic unit division is performed on the VRB domain and the PRB domain, the resource numbering may be performed on the VRB basic interleaving unit and the PRB basic interleaving unit, respectively. The numbering of the VRB basic interleaving unit and the PRB basic interleaving unit is not further limited herein.

VRB resource allocation can start allocating contiguous resources from any location and end at any location. As shown in fig. 6, if resource allocation is actually performed on part of the resource blocks (resource block 6) of the first to third VRB basic interleaving units and the fourth PRB basic interleaving unit, after interleaving mapping is correspondingly performed, resource transmission is performed on the first PRB basic interleaving unit, the second PRB basic interleaving unit, the third PRB basic interleaving unit, and the fourth PRB basic interleaving unit.

The resource block of the first VRB basic interleaving unit is mapped to the resource block 3 of the second PRB basic interleaving unit, and the resource block 2 of the second PRB basic interleaving unit is actually transmitted and is not occupied. The resource blocks of the second VRB basic interleaving unit are all mapped to the fourth PRB basic interleaving unit. Part of resource blocks (resource blocks 5) of the third VRB basic interleaving unit are mapped to the first PRB basic interleaving unit, and the rest of resource blocks (resource blocks 4) of the third VRB basic interleaving unit are mapped to resource blocks which exceed the allocated BWP, so that actual transmission is not occupied. And a resource block 6 of a fourth VRB basic interleaving unit is mapped to a resource block 4 of a third PRB basic interleaving unit, and a resource block 5 of the third PRB basic interleaving unit is actually transmitted and is unoccupied.

Further, based on the mapping relationship between the VRB basic interleaving unit and the PRB basic interleaving unit in fig. 6 and 7, for the third VRB basic interleaving unit with length L, the transmission control may be performed according to actual needs for the transmission case where the size L1 of the PRB basic interleaving unit interleaved and mapped into the BWP is smaller than L, which will be described in detail below.

Furthermore, the method for dividing the two basic interleaving units can be ensured to be consistent by limiting the starting position and the size of the BWP, so that the convention of an additional dividing method is not needed; meanwhile, the number of any basic interleaving units is L, so that the processing mode of the Orphan RB does not need to be agreed.

For example, in this embodiment, it is preferable that the starting common resource block number of the BWP is an integer multiple of the size of the basic interleaving unit, and the size of the BWP is an integer multiple of the size of the basic interleaving unit.

Thus, by adopting the dividing mode of the basic interleaving unit of the embodiment of the invention, the problem that the understanding of the division of the basic interleaving unit is inconsistent between the network side equipment and the mobile communication terminal is solved. Meanwhile, the problem that Resource Block (RB) in the same mapped basic interleaving unit is distributed in a plurality of prgs (decoding Resource block groups) due to the mismatching of the divided interleaving basic units (Resource block bundles) can be solved. The PRG is a basic mapping unit for channel estimation, and distribution in multiple PRGs may cause performance loss of channel estimation. Furthermore, the problem that mapping from VRBs to PRBs may cause Orphan PRBs due to BWP allocation or resource allocation can be solved.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
