Description

Resource scheduling method and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a resource scheduling method and a base station.

Background

In an LTE commercial system, each cell independently allocates a time-frequency Resource Block (RB) to a terminal, that is, each cell performs independent scheduling.

In the prior art, each cell independently allocates RBs to a terminal, and a Modulation and Coding Scheme (MCS) used by the terminal when the terminal is scheduled on each RB is also independently determined by each cell, and the MCS used by the terminal when the terminal is scheduled on the RB is obtained by the cell according to a Channel Quality Indicator (CQI) of the RB reported by the terminal.

However, since each cell schedules independently, and each cell does not consider the position of the RB allocated to the terminal by the neighboring cell on the spectrum resource in the independent scheduling process of the RB of the cell, that is, the co-channel interference caused by scheduling the RB by the neighboring cell on the same position of the spectrum resource is not considered in the prior art, the interference coordination between the cell and the neighboring cell cannot be effectively performed, and the accurate MCS used when the terminal is scheduled on the RB cannot be obtained by adjusting the co-channel interference of the neighboring cell when the terminal of the cell is scheduled on the current RB.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the embodiment of the present invention, assuming that a first cell and a second cell exist in a base station, please refer to fig. 1, where fig. 1 is a schematic diagram of a resource scheduling system architecture in the embodiment of the present invention, where as shown in fig. 1, in the resource scheduling system, the first cell may include a first terminal, and the second cell may include a second terminal. It should be understood that the first cell and the second cell include, but are not limited to, one or more cells.

If the base station needs to send the first amount of data to be issued to the terminal in the first cell, the base station may estimate in advance the first number of RBs needed by the first cell, that is, the base station may estimate in advance the number of RBs in the system spectrum resource of the first cell that is occupied by the base station for sending the data of the first amount of data to be issued to the terminal in the first cell; if the base station needs to send the second amount of data to be sent to the terminal in the second cell, the base station may estimate in advance the second RB needed by the second cell, that is, the base station may estimate in advance the number of RBs in the system spectrum resource of the second cell that is needed by the base station to send the data of the second amount of data to be sent to the terminal in the second cell.

In the prior art, a base station allocates a first RB with a first number of RBs to a first cell and allocates a second RB with a second number of RBs to a second cell, but does not consider co-channel interference between the first RB and the second RB, that is, the base station does not consider co-channel interference of a neighboring cell on a terminal caused by overlapping of the first RB and the second RB in a spectrum resource position. And, the base station still determines the MCS used when the terminal is scheduled on a certain RB by using the CQI on the RB reported by the terminal in the cell.

In the embodiment of the present invention, the base station may determine the first number of RBs required by the first cell according to the first amount of data to be transmitted of the first cell, and determine the second number of RBs required by the second cell according to the second amount of data to be transmitted of the second cell.

The base station may allocate a first RB of a first number of RBs to the first cell, may allocate a second RB of a second number of RBs to the second cell, and may allocate the first RB and the second RB in a staggered manner on the position of the spectrum resource when allocating, so as to avoid co-channel interference between the first RB and the second RB.

Second, the base station may acquire target parameters of a target RB, which may belong to the first RB. The base station may determine a target MCS for the target terminal to use when scheduled on the target RB in the first cell according to the target parameter.

It should be understood that the target parameter may have a corresponding relationship with the MCS, and the base station may determine, through the target parameter, the target MCS used by the target terminal when being scheduled on the target RB without co-channel interference, thereby effectively improving the data transmission efficiency of the target terminal on the target RB.

It should be noted that, in the embodiment of the present invention, if there is an overlapping RB in the spectrum resource position between the first RB and the second RB, the target RB may also belong to the overlapping RB, and the base station may obtain the target parameter of the target RB, and calculate the target MCS corresponding to the target parameter, so as to determine an accurate target MCS used when the target terminal is scheduled on the target RB, and improve the accuracy of the scheduling MCS of the terminal.

For convenience of understanding, the following describes a resource scheduling method according to an embodiment of the present invention by using specific embodiments, please refer to fig. 2, where fig. 2 shows an embodiment of a resource scheduling method according to an embodiment of the present invention, which includes:

201. a base station acquires a first data quantity to be issued of a first cell and acquires a second data quantity to be issued of a second cell;

in this embodiment, the base station may obtain the amount of data to be issued of each cell in the base station, where the amount of data to be issued may be the amount of data to be sent by the base station to the terminal in the cell. The data volume to be issued may be a data volume occupied by a file obtained by the base station according to a request sent by the terminal to the base station, or the data volume to be issued may also be a data volume occupied by a file pushed by the base station to the terminal, and is not limited herein.

Therefore, in this embodiment, the base station may obtain the first amount of data to be transmitted of the first cell, and may obtain the second amount of data to be transmitted of the second cell. It should be noted that each cell in the base station may include, but is not limited to, a first cell and a second cell, and may also include a third cell and the like. Also, it is understood that the first cell may also include, but is not limited to, one or more cells, the second cell may also include, but is not limited to, one or more cells, and the third cell may also include, but is not limited to, one or more cells.

It can be understood that the first amount of data to be issued by the base station in the first cell may be an amount of data to be issued by the base station to the terminal (including the first terminal) in the first cell, and the second amount of data to be issued by the base station in the second cell may be an amount of data to be issued by the base station to the terminal (including the second terminal) in the second cell.

202. The base station determines a first RB number required by a first cell and determines a second RB number required by a second cell;

in this embodiment, according to the first to-be-transmitted data size of the first cell and the second to-be-transmitted data size of the second cell acquired by the base station, the base station may determine the number of RBs of the first cell that needs to be occupied for transmitting the first to-be-transmitted data size, and may determine the number of RBs of the second cell that needs to be occupied for transmitting the second to-be-transmitted data size.

It should be noted that the base station may determine the first number of RBs according to the first amount of data to be transmitted and the spectral efficiency of the terminal in the first cell when being scheduled on each RB on the spectral resource of the first cell, and may determine the second number of RBs according to the second amount of data to be transmitted and the spectral efficiency of the terminal in the second cell when being scheduled on each RB on the system spectral resource of the second cell. The base station may determine the spectral efficiency of the terminal when scheduled on a certain RB, that is, may determine the amount of data that the terminal can transmit on the RB.

In this embodiment, the base station may determine the first RB number required by the first cell or the second RB number required by the second cell by accumulating the data amount that the terminal can transmit on each RB until the first data amount to be transmitted or the second data amount to be transmitted can be accommodated, where the first RB number and the second RB number are the accumulated RB numbers. It should be noted that, if the accumulated (amount of data that can be transmitted) is greater than or equal to the first amount of data to be transmitted (or the second amount of data to be transmitted) in the accumulation process, when the first RB is accumulated, that is, when the first RB is accumulated to the threshold RB, the base station may use the threshold RB as the last accumulated RB, so as to count the first RB number (or the second RB number). It can be understood that the base station may accumulate the number of RBs to be transmitted by different terminals on the cell RB according to the amount of data to be transmitted to different terminals in the same cell.

Specifically, in the process that the base station determines the first number of RBs needed by the first cell, the base station may calculate the spectral efficiency when the first terminal in the first cell is scheduled on one RB in the system spectrum resources of the first cell as follows:

the base station may receive a first parameter of a first target RB reported by the first terminal, where the first target RB is a certain RB in the system spectrum resources of the first cell. The base station may query a first MCS corresponding to the first parameter, where the first parameter may be a Signal to Interference plus Noise Ratio (SINR), a correspondence between the SINR and the MCS may be obtained by directly looking up a table, and the correspondence table between the SINR and the MCS is different due to different base station equipment providers, which is not limited in this embodiment.

Then, after determining the first MCS used by the first terminal when being scheduled on the first target RB, the base station may query the spectral efficiency corresponding to the first MCS, where a correspondence between the MCS and the spectral efficiency may also be obtained directly by looking up a table, and the correspondence table between the MCS and the spectral efficiency is different according to different providers of the base station devices, which is not limited in this embodiment.

It should be noted that the base station may calculate a first parameter of the first target RB, and the calculation may be to use a product of the target factor T and the first SINR as the first parameter. It can be understood that the first SINR may be an SINR of the first target RB obtained by the first terminal during measurement, and the first terminal may report the measured first SINR to the base station. It can be understood that the first terminal may periodically measure the SINR of the first target RB, and the measurement period is not limited in this embodiment.

The formula for the base station to calculate the target factor T may be as follows:

the second measurement time parameter may be an interference parameter of a second cell received by the first terminal, and it can be understood that the first terminal may report the interference parameter to the base station when reporting the first SINR to the base station, where the interference parameter may be Reference Signal Receiving Power (RSRP); the constant P may be a very small constant, e.g. 10^-13Etc.; and when the first terminal measures the first SINR, if the second cell schedules the RB in the same position as the first target RB in the system spectrum resources of the second cell, X is 1, and if the second cell does not schedule the RB in the same position as the first target RB, X is 0.

Note that, if the second Cell does not schedule an RB at the same position as the first target RB, but the positions of Resource Elements (REs) used by Cell-Specific Reference signals (CRSs) in the RBs at the same position as the first target RB in the second Cell are the same, X also takes 1.

And when the base station schedules the first target RB, if the base station schedules all RBs on the system spectrum resource of the second cell, that is, the second cell is in a full-load state, Y is 1, and if the base station does not schedule all RBs on the system spectrum resource of the second cell, that is, the second cell is in a non-full-load state, Y is 0. It is to be understood that the idle state is a state in which the cell does not schedule any RB, and the non-idle state is a state in which a certain RB in the system spectrum resources of the cell is scheduled.

It should be noted that, when the base station schedules all RBs on the system spectrum resource of a certain cell, the cell is in a full load state; when the base station does not schedule all RBs on the system spectrum resource of the cell, that is, the cell is in a non-full state, the following restriction is not repeated after the restriction in this embodiment.

It is to be understood that, if a plurality of cells, such as the first cell, the second cell and the third cell, are included in the base station, in the above formula for calculating the target factor T, the formula may be as follows:

wherein the second measurement time parameter is X₁*RSRP₁+X₂*RSRP₂+ P, here may be in RSRP₁For the interference parameter, RSRP, of the second cell received by the first terminal₂Taking the interference parameter of the third cell received by the first terminal as an example; when the first terminal measures the first SINR, X is carried out if the second cell schedules the RB at the same position as the first target RB₁Taking 1, if the second cell does not schedule the RB at the same position as the first target RB, X₁Taking 0; if the third cell schedules the same position RB as the first target RB, X₂Taking 1, if the third cell does not schedule the RB at the same position as the first target RB, X₂Take 0.

If the second cell does not schedule the RB at the same position as the first target RB, but the positions of REs used by CRSs in the RBs at the same position as the first target RB in the second cell are the same, the X is₁Taking 1 as well; if the third cell does not schedule the RB with the same position as the first target RB but the position of the RE used by the CRS in the RB with the same position as the first target RB in the third cell is the same, the X₂Also take 1.

The second scheduling time parameter is Y₁*RSRP₁+Y₂*RSRP₂+ P, and Y if the second cell is in full load state when the base station schedules the first target RB₁Taking 1, if the second cell is in a non-full load state, Y₁Taking 0; if the third cell is in full load state, Y₂Taking 1, if the third cell is in a non-full load state, Y₂Take 0.

It should be understood that, in the process of determining the second number of RBs needed by the second cell, the base station may calculate the spectral efficiency of the second terminal in the second cell when the second terminal is scheduled on one of the RBs in the system spectrum resource of the second cell as follows:

the base station may receive a second parameter of a second target RB reported by the second terminal, where the second target RB is a certain RB in the system spectrum resource of the second cell. The base station may query the second MCS corresponding to the second parameter, where the second parameter may be a signal to interference plus noise ratio SINR, and a table lookup may be directly performed to obtain a corresponding relationship between the SINR and the MCS. The base station may obtain a second MCS used when the second terminal is scheduled on the second target RB by looking up a table, and the base station may query the spectral efficiency corresponding to the second MCS.

It should be noted that the base station may calculate the second parameter of the second target RB, and the calculation may be to use the product of the target factor T' and the second SINR as the second parameter. It is to be understood that the second SINR may be an SINR of the second target RB obtained by the second terminal during measurement, and the second terminal may report the measured second SINR to the base station. It can be understood that the second terminal may periodically measure the SINR of the second target RB, and the measurement period is not limited in this embodiment.

The formula for the base station to calculate the target factor T' may be as follows:

the third measurement time parameter ═ X' × a third interference parameter + constant P, where the third interference parameter may be an interference parameter of the first cell received by the second terminalIt can be understood that the second terminal may report the interference parameter to the base station when reporting the second SINR to the base station, where the interference parameter may also be reference signal received power RSRP; the constant P may also be a very small constant, e.g. 10^-13Etc.; when the second terminal measures the second SINR, if the first cell schedules the RB at the same position as the second target RB, X 'is set to 1, and if the first cell does not schedule the RB at the same position as the second target RB, X' is set to 0.

Note that, if the first cell does not schedule the RB at the same position as the second target RB, X' may be 1 if the position of the RE used by the CRS is the same in the RB at the same position as the second target RB in the first cell.

The third scheduling time parameter is Y ' × third interference parameter + the constant P, and when the base station schedules the second target RB, Y ' takes 1 if the base station determines that the first cell is in a full load state, and Y ' takes 0 if the first cell is in a non-full load state.

It is to be understood that, if a plurality of cells, such as the first cell, the second cell and the third cell, are included in the base station, the formula for calculating the target factor T' may be further as follows:

the target factor T' is in the third measurement time parameter/the third scheduling time parameter;

wherein the third measurement time parameter is X₁’*RSRP₁+X₂’*RSRP₂+ P, where RSRP may be used here₁For the interference parameter, RSRP, of the first cell received by the second terminal₂Interference parameters of a third cell received by the second terminal; when the second terminal measures the second SINR, if the first cell schedules the RB at the same position as the second target RB, X₁' get 1, if the first cell does not schedule the same position RB as the second target RB, then X₁' take 0; if the third cell schedules the RB at the same position as the second target RB, X₂' get 1, if the third cell does not schedule the same position RB as the second target RB, X₂' take 0.

It is to be noted thatWhen a cell does not schedule the same position of RB as the second target RB but the position of RE used by CRS in the same position of RB as the second target RB in the first cell is the same, the X₁' also can take 1; if the third cell does not schedule the RB with the same position as the second target RB but the position of the RE used by the CRS in the RB with the same position as the second target RB in the third cell is the same, the X₂' may also take 1.

Third scheduling time parameter Y₁’*RSRP₁+Y₂’*RSRP₂+ P, and Y if the first cell is in full load state when the base station schedules the second target RB₁' get 1, if the first cell is not fully loaded, then Y₁' take 0; if the third cell is in full load state, Y₂If the third cell is not fully loaded, then Y is taken to be 1₂Taking 0, it is understood that the third RB may be determined by the base station according to a third amount of data to be transmitted in a third cell, where a process of determining the third RB by the base station may be similar to a process of determining the first RB by the base station or a process of determining the second RB by the base station, and details are not repeated here.

In this embodiment, through iteration, the base station may improve the accuracy of the estimated required first RB number or second target RB number. Taking the first cell and the second cell as an example, for example: the base station calculates the spectral efficiency of the first terminal on the first target RB, and when calculating the second scheduling time parameter, the base station can calculate the second scheduling time parameter according to the state (in a full-load state or a non-full-load state) of a second cell when the first target RB is currently scheduled, and can calculate the spectral efficiency of the first target RB; the base station may determine, according to the calculated spectral efficiency of the first terminal on the first target RB, whether the first RB in the first cell occupies the system spectrum resource of the first cell (the first RB occupies the system spectrum resource of the first cell and is in a full-load state, and the first RB does not occupy the system spectrum resource of the first cell and is in a non-full-load state), and the base station may calculate a third scheduling time parameter and calculate a spectral efficiency of the second terminal on the second target RB; according to the calculated spectral efficiency of the second terminal on the second target RB, the base station may determine whether the second RB in the second cell occupies the system spectral resources of the second cell, that is, the base station may determine the state of the second cell at this time (the second RB occupies the system spectral resources of the second cell and is in a full-load state, and the second RB does not occupy the system spectral resources of the second cell and is in a non-full-load state), at this time, the base station may calculate the spectral efficiency of the first terminal on the first target RB again, and when calculating the second scheduling time parameter, Y takes 1 if the second cell is in a full-load state, and Y takes 0 if the second cell is in a non-full-load state, thereby calculating the second scheduling time parameter and calculating the spectral efficiency of the first target RB; the base station may determine whether the first RB occupies the system spectrum resource of the first cell according to the recalculated spectrum efficiency of the first target RB, and the base station may calculate the third scheduling time parameter and recalculate the spectrum efficiency of the second terminal on the second target RB, and repeat the above steps until the states of the first cell and the second cell do not change any more.

203. The base station distributes a first RB and a second RB according to a preset rule;

in this embodiment, the base station may allocate a first number of RBs on the system spectrum resource of the first cell, that is, a first RB, and allocate a second number of RBs on the system spectrum resource of the second cell, that is, a second RB, according to a preset rule, where the base station may stagger the first RB from the second RB on a spectrum resource position, that is, a position where the RB is located in the system spectrum resource.

It should be noted that the preset rule for the base station to allocate the first RB and the second RB may be a static allocation rule, such as: the base station may partition a first location and a second location in the system spectrum resources for the first cell and the second cell, respectively, such that the base station may allocate a first RB for the first cell in the first location and a second RB for the second cell in the second location. It is to be understood that the first location may include, but is not limited to, one or more locations, the second location may also include, but is not limited to, one or more locations, and if a third cell exists in the base station, the base station may also partition the third cell into a third location in its system spectrum resource, which is not limited herein.

It should be noted that the preset rule for the base station to allocate the first RB and the second RB may also be a dynamic allocation rule, such as: the base station may allocate a second RB to the second cell after allocating the same spectral resource location as the first RB in the system spectral resources of the second cell.

It can be understood that, if the sum of the numbers of RBs in the first RB and the second RB is greater than the number of RBs in the cell spectrum resource, the base station may preferentially stagger the first RB and the second RB in the spectrum resource position, which cannot be staggered, and the base station may allocate them in the same spectrum resource position as the neighboring cell.

204. A base station acquires target parameters of a target RB;

in this embodiment, taking a target RB in a first RB belonging to a first cell as an example, the base station may obtain a target parameter of the target RB, where the target parameter may be associated with an MCS used when a target terminal is scheduled on the target RB, and the target parameter may also be a signal to interference plus noise ratio SINR.

It should be noted that the base station may calculate the target parameter of the target RB, and the calculation may be to take the product of the target factor K and the target SINR as the target parameter. It is to be understood that the target SINR may be a target SINR of the target RB obtained by the target terminal during measurement, and the target terminal may report the measured target SINR to the base station. It can be understood that the target terminal may periodically measure the SINR of the target RB, and the measurement period is not limited in this embodiment.

The formula for the base station to calculate the target factor K may be as follows:

the first measurement time parameter may be M × first interference parameter + constant Q, where the first interference parameter may be an interference parameter of a second cell received by the target terminal, and it may be understood that the target terminal may report the target SINRReporting the interference parameter to a base station when the base station is reached, wherein the interference parameter can also be Reference Signal Received Power (RSRP); the constant Q may also be a very small constant, e.g. 10^-13Etc.; when the target terminal measures the target SINR, M is 1 if the second cell schedules the RB at the same position as the target RB, and M is 0 if the second cell does not schedule the RB at the same position as the target RB.

Note that, if the second cell does not schedule the RB at the same position as the target RB, the position of the RE used by the CRS in the RB at the same position as the target RB in the second cell may be 1.

The first scheduling time parameter is N × first interference parameter + the constant Q, and when the base station schedules the target RB, if the first RB and the second RB overlap on a spectrum resource position and the target RB belongs to the overlapping RB, N is 1, and if the target RB does not belong to the overlapping RB, N is 0.

It is to be understood that, if a plurality of cells, such as the first cell, the second cell and the third cell, are included in the base station, the formula for calculating the target factor K may be as follows:

the target factor K is in the first measurement time parameter/first scheduling time parameter;

wherein the first measurement time parameter is M₁*RSRP₁+M₂*RSRP₂+ Q, where here may be at RSRP₁Interference parameter, RSRP, of the second cell received for the target terminal₂Taking the interference parameter of the third cell received by the target terminal as an example; when the target terminal measures the target SINR, M is carried out if the second cell schedules the RB at the same position of the target RB₁Taking 1, if the second cell does not schedule the RB at the same position of the target RB, M₁Taking 0; m if the third cell schedules the RB at the same position as the target RB₂Taking 1, if the third cell does not schedule the RB at the same position of the target RB, M₂Taking 0;

if the second cell does not schedule the RB at the same position as the target RB, the target RB is located at the same position as the RE used by the CRS in the RB at the same position as the target RB in the second cellAt the same time, the M₁Or 1 may be taken. If the third cell does not schedule the RB with the same position as the target RB but the position of the RE used by the CRS in the RB with the same position as the target RB in the third cell is the same, the M₂Or 1 may be taken.

The first scheduling time parameter is N₁*RSRP₁+N₂*RSRP₂+ Q, when the base station schedules the target RB, if the first RB and the second RB overlap on the position of the frequency spectrum resource, and the target RB belongs to the overlapped RB, then N₁Take 1, if the target RB does not belong to the overlapped RB, then N₁Taking 0;

if the first RB and the third RB overlap in the position of the frequency spectrum resource and the target RB belongs to the overlapped RB, N is₂Take 1, if the target RB does not belong to the overlapped RB, then N₂Take 0.

It can be understood that the third RB may be determined by the base station according to a third amount of data to be transmitted in a third cell, where a process of determining the third RB by the base station may be similar to a process of determining the first RB by the base station or a process of determining the second RB by the base station, and details are not repeated here.

205. And the base station determines a target MCS used when the target terminal is scheduled on the target RB according to the target parameters.

In this embodiment, the base station may query a target MCS corresponding to the target parameter, where the target parameter may be an SINR, and the mapping relationship between the MCS and the SINR may be obtained by looking up a table directly.

It can be understood that, in this embodiment, based on the co-channel interference of the RBs of the neighboring cells, the base station may recalculate the MCS used by the terminal on the RB in the system spectrum resource and use the MCS to schedule the terminal on the RB, thereby improving the data transmission efficiency of the terminal in each cell and the accuracy of the MCS used in scheduling.

In this embodiment, the base station may obtain a first amount of data to be issued of the first cell, and may obtain a second amount of data to be issued of the second cell; the base station can determine a first RB number required by the first cell according to the first data quantity to be transmitted, and can determine a second RB number required by the second cell according to the second data quantity to be transmitted; the base station may allocate a first cell first RB according to a first number of RBs and a second cell second RB according to a second number of RBs; then, the base station may obtain a target parameter of a target RB, the target RB belonging to the first RB; the base station can determine the target MCS used by the target terminal when being scheduled on the target RB according to the target parameter, thereby effectively improving the data transmission efficiency of the target terminal and the accuracy of the MCS used when being scheduled.
