Technical Field
The disclosure relates to the technical field of communication, and in particular relates to a resource allocation method, a device, equipment and a medium.
Background
With the construction of a 5G communication network, a terminal device in each cell within the signal coverage of a base station is allocated with a suitable physical uplink data shared channel (physical uplink shared channel, PUSCH) resource, which often determines uplink performance.
Currently, allocation of PUSCH resources in the industry is generally determined by obtaining the result of cell PCI modulo N (n=2, or 3 in general) to determine a manner of allocating PUSCH resources for terminal devices in a cell. However, this approach may result in PUSCH resources allocated for a terminal device in one cell being the same or close to PUSCH resources allocated for a terminal device in another neighboring cell, once the result of PCI modulo N is the same between cells. Thus, when the terminal equipment in the cell communicates with the base station, the uplink signal of the terminal equipment located at the edge of one cell and the uplink signal of the terminal equipment located at the edge of another adjacent cell are easy to interfere with each other, so that the perception of the terminal equipment is poor and the throughput of the cell is reduced.

Technical effects provided by embodiments of the present disclosure may include the following beneficial effects:
According to the technical scheme, after the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the cell corresponding to the base station are obtained, the frequency domain segmentation number of the cell in different frequency bands is obtained according to the number of the resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the cell, the resource allocation starting position corresponding to each terminal device is obtained according to the RNTI corresponding to each terminal device in the cell, the frequency domain segmentation number of the cell and the first parameter of the cell, and PUSCH resource indication information for indicating PUSCH resources is generated and transmitted according to the resource allocation starting position corresponding to each terminal device in the cell and the resource block required number of each terminal device in the cell. Because the PUSCH resources are not directly allocated based on the result of the cell PCI modulo N in the scheme, the RNTI of each terminal device is combined to determine the PUSCH resource allocation starting position corresponding to each terminal device. Even in the neighboring cells, because the corresponding RNTI of the terminal equipment in each cell is different, the determined resource allocation starting positions are different, so that the PUSCH resources actually allocated to the terminal equipment in each cell can be ensured to be staggered as far as possible. Therefore, when the terminal equipment in the cell communicates with the base station, the uplink signal of the terminal equipment positioned at the edge of one cell and the uplink signal of the terminal equipment positioned in another adjacent cell can be prevented from interfering with each other, and the perception of the terminal equipment and the throughput of the cell are improved.

Fig. 1 shows a schematic view of a scenario according to an embodiment of the present disclosure.
As shown in fig. 1, base stations 111 to 113, terminal devices 121 to 129 may be included in the scene. Wherein terminal devices 121 to 124 are located in an edge region in cell 1, terminal devices 125 and 126 are located in an edge region in cell 2, and terminal devices 127 to 129 are located in an edge region in cell 3.
A base station may provide communication coverage for a particular geographic area and may communicate with terminal devices within the coverage area, and the base station may also receive signals from terminal devices within its coverage area. As shown in fig. 1, cell 1 is located within the signal coverage of base station 111, cell 2 is located within the signal coverage of base station 113, and cell 3 is located within the signal coverage of base station 112. Base station 111 may communicate with any one or more of terminal devices 121 through 124, base station 113 may communicate with terminal device 125 or terminal device 126, and base station 112 may communicate with any one or more of terminal devices 127 through 129.
The base station may allocate uplink PUSCH resources for each terminal device within the signal coverage range, so that the terminal device may send control information or transmit data to the base station through the corresponding PUSCH resources.
It should be understood that the base station shown in fig. 1 is only exemplary, and other devices having the same function are also possible, and the present application is not limited in this regard.
It should be understood that the number of base stations, cells and terminal devices shown in fig. 1 is merely illustrative, and that other numbers of base stations and terminal devices may be included in the scenario shown in fig. 1, and that the number of cells covered by each base station may be greater, which the present application is not limited to.
Currently, when a base station allocates PUSCH resources to each terminal device in a signal coverage area, a method for allocating PUSCH resources to a terminal device in a cell is generally determined by acquiring a result of a cell PCI modulo N (normally, n=2, or 3). When the cell adopts broadband allocation (also called two-stage allocation) to allocate the PUSCH resources, the result of the PCI module 2 of the cell can be obtained, and when the result of the PCI module 2 is 0, the PUSCH resources are allocated to the terminal equipment in the cell from low frequency to high frequency; when the result of the PCI mode 2 is 1, PUSCH resources are allocated from high frequency to low frequency for the terminal devices in the cell. When the cell adopts three-section allocation to allocate the PUSCH resources, the result of the PCI module 3 of the cell can be obtained, and when the result of the PCI module 3 is 0, the PUSCH resources are allocated to the terminal equipment in the cell from low frequency to high frequency; when the result of the PCI model 3 is 1, distributing PUSCH resources from the medium frequency to the high frequency for terminal equipment in the cell; when the result of the PCI mode 3 is 2, PUSCH resources are allocated from high frequency to low frequency for the terminal devices in the cell.
However, whatever the manner of PUSCH resources are allocated as described above, once the result of PCI modulo N is the same between cells, it may result in PUSCH resources allocated for a terminal device in one cell being the same as or close to PUSCH resources allocated for a terminal device in another neighboring cell. Thus, when the terminal equipment in the cell communicates with the base station, the uplink signal of the terminal equipment located at the edge of one cell and the uplink signal of the terminal equipment located at the edge of another adjacent cell are easy to interfere with each other, so that the perception of the terminal equipment is poor and the throughput of the cell is reduced. For example, assuming that the cells 1 to 3 shown in fig. 1 all adopt two-stage allocation and the results of the modes 2 of the cells 1 to 3 are equal, or that the cells 1 to 3 shown in fig. 1 all adopt three-stage allocation and the results of the modes 3 of the cells 1 to 3 are equal, each base station allocates PUSCH resources to terminal devices within the coverage area of the respective signals by adopting the same PUSCH resource allocation method, and then mutual interference of uplink signals may occur between the terminal devices 121 located in the edge area of the cell and the terminal devices 129.
In view of the above-mentioned drawbacks, the present disclosure provides a resource allocation method, by acquiring the number of resource blocks corresponding to a partial bandwidth configured by a base station and a first parameter of a cell corresponding to the base station, acquiring the frequency domain segmentation numbers of the cell in different frequency bands according to the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the cell, acquiring a resource allocation starting position corresponding to each terminal device according to an RNTI corresponding to each terminal device in the cell, the frequency domain segmentation numbers of the cell and the first parameter of the cell, and generating and transmitting PUSCH resource indication information for indicating PUSCH resources according to the resource allocation starting position corresponding to each terminal device in the cell and the resource block requirement number of each terminal device in the cell. Since the present disclosure does not directly allocate PUSCH resources based on the result of the cell PCI modulo N, but combines the RNTI of each terminal device to determine the PUSCH resource allocation starting position corresponding to each terminal device. Even in the neighboring cells, because the corresponding RNTI of the terminal equipment in each cell is different, the determined resource allocation starting positions are different, so that the PUSCH resources actually allocated to the terminal equipment in each cell can be ensured to be staggered as far as possible. Therefore, when the terminal equipment in the cell communicates with the base station, the uplink signal of the terminal equipment positioned at the edge of one cell and the uplink signal of the terminal equipment positioned in another adjacent cell can be prevented from interfering with each other, so that the perception of the terminal equipment and the throughput of the cell are improved.

In an embodiment of the present disclosure, the resource allocation starting position may be specifically understood as a resource block identifier corresponding to a starting resource block occupied by a PUSCH allocated by a base station for a terminal device in a first slot.
In an embodiment of the present disclosure, the PUSCH resource indication information is specifically configured to indicate, in a first slot, a resource block identifier corresponding to a resource block occupied by a PUSCH allocated by a base station for a terminal device. It can be understood that the number of resource blocks occupied by PUSCH is determined by the number of resource block requirements of the terminal device, and the starting position of the resource blocks occupied by PUSCH is determined by the starting position of resource allocation.
It should be appreciated that in this disclosure, each resource block corresponds to one resource block identity.
In an embodiment of the present disclosure, when the base station transmits PUSCH resource indication information to the terminal device, the PUSCH resource indication information may be specifically transmitted through downlink control information (downlink control information, DCI).

Thus, by this embodiment, PUSCH resource allocation for each terminal device located in a cell within the signal coverage of a base station can be achieved. Obviously, the embodiment is executed in each time slot, so that PUSCH frequency domain resource allocation in each time slot can be realized for each terminal device in a cell within the signal coverage of the base station.
Since this embodiment does not allocate PUSCH resources directly based on the result of the cell PCI modulo N, but combines the RNTI of each terminal device to determine the PUSCH resource allocation starting position corresponding to each terminal device. Even in the neighboring cells, because the corresponding RNTI of the terminal equipment in each cell is different, the determined resource allocation starting positions are different, so that the PUSCH resources actually allocated to the terminal equipment in each cell can be ensured to be staggered as far as possible. Therefore, when the terminal equipment in the cell communicates with the base station, the uplink signal of the terminal equipment positioned at the edge of one cell and the uplink signal of the terminal equipment positioned in another adjacent cell can be prevented from interfering with each other, so that the perception of the terminal equipment and the throughput of the cell are improved.
In an embodiment of the present disclosure, step 202, that is, obtaining the frequency domain segmentation number of the cell in different frequency bands according to the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the cell, may be specifically implemented by executing the following process (i) or (ii).
(i) Responding to the resource allocation mode of the first cell corresponding to the base station to allocate in two sections, acquiring the frequency domain segmentation number of the first cell corresponding to the low frequency band based on a first preset formula according to the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the first cell, and acquiring the frequency domain segmentation number of the first cell corresponding to the high frequency band based on a second preset formula;

In the present disclosure, among cells corresponding to a base station, a cell whose resource allocation pattern is two-stage allocation may be referred to as a first cell, and a cell whose resource allocation pattern is three-stage allocation may be referred to as a second cell.
In this embodiment, after the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter of the cell located in the coverage area of the base station are obtained in the first time slot in step 201, the frequency domain segmentation number of the cell in different frequency bands in the first time slot can be further determined in step 202. For any cell, when determining the frequency domain segmentation number of the cell in different frequency bands, if judging that the resource allocation mode of the cell is two-segment allocation, determining the frequency domain segmentation number corresponding to the cell in a low frequency band and the frequency domain segmentation number corresponding to a high frequency band; if the resource allocation mode of the cell is three-segment allocation, determining the frequency domain segmentation number corresponding to the low frequency band, the frequency domain segmentation number corresponding to the medium frequency band and the frequency domain segmentation number corresponding to the high frequency band.
Whether the resource allocation mode corresponding to the cell is two-segment allocation or three-segment allocation, whether the frequency domain segmentation number corresponding to the cell in the low frequency band, the frequency domain segmentation number corresponding to the medium frequency band or the frequency domain segmentation number corresponding to the high frequency band is determined, the frequency domain segmentation number of the cell in the corresponding frequency band can be determined according to the number of resource blocks corresponding to the partial bandwidth configured by the base station and the first parameter corresponding to the cell in the first time slot acquired in the step 201 and through a corresponding preset formula.

As another example, as shown in fig. 1, assuming that the resource allocation modes corresponding to the cell 1, the cell 2 and the cell 3 are all three-segment allocations (that is, the cell 1, the cell 2 and the cell 3 are all second cells), the frequency domain segmentation numbers corresponding to the cell 1 in the low frequency band, the middle frequency band and the high frequency band and the frequency domain segmentation numbers corresponding to the cell 2 in the low frequency band, the middle frequency band and the high frequency band respectively can be determined based on the third preset formula, the fourth preset formula and the fifth preset formula respectively through the number of resource blocks corresponding to the partial bandwidths configured by each base station and the first parameters corresponding to the three cells respectively.

In this embodiment, if it is determined that the resource allocation mode corresponding to the cell is three-segment allocation, the number of frequency domain segments corresponding to the cell in the intermediate frequency band is determined by a fourth preset formula in the first time slot according to the number of resource blocks corresponding to the partial bandwidth configured by the base station and the number of resource blocks occupied by the PUSCH average scheduled by the cell in the first time slot.
