Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows a flowchart of a frequency domain resource allocation method provided in this embodiment, including:
s101, determining the total number of PRBs needed by the current user and the number of PRBs in each RBG configured by the bandwidth of the cell to which the current user belongs.
The current user refers to a user terminal, such as a mobile phone or a computer, with which the user wants to communicate with the outside.
In implementation, when a current user wants to communicate with the outside, whether frequency domain resources are allocated to the current user through a Type0 frequency domain allocation mode can be determined according to the number of PRBs that the current user needs to occupy and the actual PRB utilization rate. Specifically, first, the total number of frequency domain PRBs required by the current user, that is, the total number of PRBs required by the current user, may be determined according to the size of a data packet to be transmitted by the current user. Then, the cell bandwidth of the cell to which the current user belongs may be determined, and the number of PRBs included in each RBG of the cell bandwidth configuration of the cell to which the current user belongs may be determined.
It is understood that the number of RBGs corresponding to the aforementioned cell bandwidth can also be determined based on the number of PRBs contained in each RBG of the aforementioned cell bandwidth configuration. Taking the number of PRBs corresponding to the cell Bandwidth as 273 as an example, according to table 1 (where, bandwidth Part Size represents the cell Bandwidth, and Configuration represents the number of PRBs included in each RBG), it may be obtained that the number of PRBs in each RBG of the cell Bandwidth Configuration is 16, and then it may be determined that the number of RBGs corresponding to the cell Bandwidth is 18, and the first 17 RBGs all include 16 PRBs, and the last RBG all includes 1 PRB.
TABLE 1
| Bandwidth Part Size | Configuration 1 |
| 1-36 | 2 |
| 37-72 | 4 |
| 73-144 | 8 |
| 145-275 | 16 |
S102, determining the actual PRB utilization rate based on the total number of PRBs required by the current user and the number of PRBs in each RBG configured by the cell bandwidth.
The actual PRB utilization rate refers to the proportion of the total number of PRBs required by the current user in the total number of PRBs actually occupied by the user.
In implementation, after determining the number of PRBs in each RBG of the cell bandwidth configuration to which the current user belongs, an actual PRB utilization rate may be calculated based on the total number of PRBs required by the current user and the number of PRBs in each RBG of the cell bandwidth configuration to which the current user belongs, so as to determine different frequency domain resource allocation manners based on the actual PRB utilization rate.
S103, acquiring a preset minimum PRB utilization rate, and distributing frequency domain resources for the current user in a Type0 frequency domain distribution mode when the actual PRB utilization rate is greater than or equal to the preset minimum PRB utilization rate.
The preset minimum PRB utilization rate refers to a preset threshold value for selecting different frequency domain Allocation modes, that is, when the actual PRB utilization rate is greater than or equal to the threshold value, a Type0 frequency domain Allocation mode is adopted, otherwise, a Type1 (Resource Allocation Type1 ) frequency domain Allocation mode is adopted.
In implementation, after the actual PRB utilization rate is determined, a corresponding frequency domain resource allocation manner may be selected based on a size relationship between the actual PRB utilization rate and a preset minimum PRB utilization rate. The method for performing frequency domain resource allocation may include a Type0 frequency domain allocation method and a Type1 frequency domain allocation method, wherein the Type0 frequency domain allocation method performs resource allocation with RBG as a granularity, and the allocated frequency domain resources may be discontinuous; the Type1 frequency domain allocation mode is to allocate resources with PRB as granularity, the allocated frequency domain resources need to be continuous, and the success rate of the Type0 frequency domain allocation mode is usually higher than that of the Type1 frequency domain allocation mode. Specifically, first, a preset minimum PRB utilization rate may be obtained, and the actual PRB utilization rate is compared with the preset minimum PRB utilization rate to determine whether the actual PRB utilization rate is greater than or equal to the preset minimum PRB utilization rate. When the actual PRB utilization rate is greater than or equal to the preset minimum PRB utilization rate, corresponding frequency domain resources can be allocated to the current user in a Type0 frequency domain allocation mode. Taking the actual PRB utilization rate as 94% as an example, assuming that the preset minimum PRB utilization rate is 90%, at this time, it may be determined to allocate the corresponding frequency domain resource to the current user in a Type0 frequency domain allocation manner.
According to the technical scheme, the frequency domain resources are allocated to the user in a type0 frequency domain allocation mode by determining the actual PRB utilization rate, setting the preset minimum PRB utilization rate and when the actual PRB utilization rate is higher than the preset minimum PRB utilization rate. Therefore, when the actual PRB utilization rate is higher than the preset minimum utilization rate, the frequency domain resources are distributed in a type0 frequency domain resource distribution mode, the frequency domain distribution success rate can be guaranteed, and meanwhile the waste amount of the PRBs in the RBGs can be reduced to a certain extent, so that the frequency domain resource utilization rate can be improved to a certain extent, and further the cell throughput and the user experience can be improved to a certain extent.
Further, on the basis of the above method embodiment, the actual PRB utilization rate may be determined by determining the total number of PRBs actually occupied by the current user, and the corresponding processing of step S102 may be as follows: determining the calculated number of RBGs required by the current user based on the total number of PRBs required by the current user and the number of PRBs in each RBG configured by the cell bandwidth; determining the total number of PRBs actually occupied by the current user based on the number of PRBs in each RBG configured by the cell bandwidth and the RBG calculation number required by the current user; and determining the actual PRB utilization rate based on the total number of PRBs actually occupied by the current user and the total number of PRBs required by the current user.
In implementation, when determining the actual PRB utilization, first, the calculated number of RBGs required by the current user may be determined based on the total number of PRBs required by the current user and the number of PRBs in each RBG of the cell bandwidth configuration. Then, the total number of PRBs actually occupied by the current user can be determined based on the determined number of RBG calculations required by the current user and the number of PRBs in each RBG of the cell bandwidth configuration. And then, based on the total number of PRBs actually occupied by the current user and the total number of PRBs required by the current user, determining the actual PRB utilization rate. Therefore, the actual PRB utilization rate is determined based on the total number of PRBs actually occupied by the current user and the total number of PRBs required by the current user, and the accuracy of the calculated actual PRB utilization rate can be improved, so that the frequency domain distribution mode determined based on the actual PRB utilization rate can better meet the actual requirement, the frequency domain resource utilization rate can be further improved while the frequency domain distribution success rate is ensured, and the cell throughput and the user experience are improved.
The formula for determining the actual PRB utilization may be as follows:
PRBPercent＝MaxPRBNum/(PRBNumPerRBG*RBGNum)
the PRBPercent represents the actual PRB utilization rate, the MaxPRBNum represents the total number of PRBs required by the current user, the PRBNumPERBG represents the number of PRBs in each RBG configured by the cell bandwidth to which the current user belongs, the RBGNum represents the calculated number of the RBGs required by the current user, and the PRBNumPERBG × RBGNum represents the total number of the PRBs actually occupied by the current user.
Referring to fig. 2, the total number of PRBs MaxPRBNum required by the current user is 106, and the cell to which the current user belongsThe number of PRBs in each RBG of the bandwidth configuration PRBNumPERBG is 16 as an example, and can be calculated
Rounding up 6.625 yields the number of RBG calculations RBGNum =7 required by the current user. Then, the total number of prbnumperbrg RBGNum =7 × 16=112 of PRBs actually occupied by the current user can be calculated. Then, the actual PRB utilization may be calculated as:
further, on the basis of the above method embodiment, it may be determined whether to determine a frequency domain allocation manner based on the actual PRB utilization according to the frequency domain allocation message, and the corresponding processing may be as follows: determining whether the resource allocation mode carried by the received frequency domain allocation message contains a frequency domain resource self-adaptive allocation mode; and if so, determining the total number of PRBs required by the current user according to the frequency domain resource self-adaptive distribution mode.
In an implementation, before allocating the frequency domain resources for the current user, a frequency domain allocation message, which may be an interface message, sent by an upper layer, such as a MAC (Medium Access Control media Access Control) layer, may be received. Then, it may be obtained whether the resource allocation manner carried in the frequency domain allocation message includes a frequency domain resource adaptive allocation manner, and it may be understood that the resource allocation manner carried in the frequency domain allocation message may be one of a Type0 frequency domain allocation manner, a Type1 frequency domain allocation manner, and a frequency domain resource adaptive allocation manner. If so, the total number of PRBs required by the current user may be determined according to the frequency domain resource adaptive allocation manner, that is, if the frequency domain allocation message carries the frequency domain resource adaptive allocation manner, the processing procedures in steps S101 to S103 may be performed. Therefore, according to the resource allocation mode carried by the frequency domain allocation message, which frequency domain allocation mode is adopted to allocate the frequency domain resources for the user is determined, so that the time consumption of frequency domain allocation can be reduced to a certain extent, the allocation efficiency is improved, and the cell throughput and the user experience can be further improved.
Further, on the basis of the above method embodiment, when the actual PRB utilization is less than the preset minimum PRB utilization, a Type1 frequency domain allocation may also be used, and the corresponding processing may be as follows: and when the actual PRB utilization rate is less than the preset minimum PRB utilization rate, distributing the frequency domain resources for the current user in a Type1 frequency domain distribution mode.
In an implementation, it is considered that although the success rate of the Type0 frequency domain allocation method is higher than that of the Type1 frequency domain allocation method, the frequency domain resource utilization rate of the Type0 frequency domain allocation method is lower than that of the Type1 frequency domain allocation method, and therefore, the Type1 frequency domain allocation method can be selected when the actual PRB utilization rate is less than the preset minimum PRB utilization rate. Specifically, after the relation between the actual PRB utilization rate and the preset minimum PRB utilization rate is determined, if the actual PRB utilization rate is less than the preset minimum PRB utilization rate, a Type1 frequency domain allocation mode may be adopted, that is, frequency domain resources may be allocated to the current user through the Type1 frequency domain allocation mode. Therefore, the frequency domain resource occupancy rate of the Type1 frequency domain allocation mode is usually high and even can be one hundred percent, so that the utilization rate of the frequency domain resources can be further improved on the basis of ensuring the success rate of frequency domain resource allocation, and the cell throughput and the user experience can be further improved.
Referring to fig. 3, taking the total number of PRBs needed by the current user MaxPRBNum as 97 and the number of prbnumperrbgs in each RBG configured by the cell bandwidth to which the current user belongs as 16 as an example, it can be calculated
Rounding up 6.0625 may result in the number of RBG calculations RBGNum =7 required by the current user. The total number of PRBs actually occupied by the current user is:
PRBNumPerRBG*RBGNum＝16*7＝112
then, the actual PRB utilization may be calculated as:
still assuming that the preset minimum PRB utilization is 90%, at this time, it may be determined that frequency domain resources are allocated to the current user in a Type1 frequency domain allocation manner.
Further, on the basis of the above method embodiment, when allocation fails in the Type1 frequency domain allocation manner, reallocation may also be performed in the Type0 frequency domain allocation manner, and the corresponding processing may be as follows: and when the frequency domain resources are unsuccessfully allocated in the Type1 frequency domain allocation mode, reallocating the frequency domain resources for the current user in the Type0 frequency domain allocation mode.
In the implementation, considering that the success rate of the Type1 frequency domain allocation method is relatively low, the frequency domain resource allocation can be continued by using the Type0 frequency domain allocation method when the Type1 frequency domain allocation method fails. Specifically, when it is monitored that the frequency domain resources are unsuccessfully allocated to the current user in the Type1 frequency domain allocation mode, the frequency domain resources can be reallocated to the current user in the Type0 frequency domain allocation mode, so that the current user can normally communicate with the outside based on the allocated frequency domain resources. Therefore, the success rate of frequency domain resource allocation can be further improved, and the cell throughput and the user experience can be further improved.
Referring to fig. 4, first, it may be determined whether a frequency domain allocation message carries a frequency domain resource adaptive allocation manner, and if not, and a Type1 frequency domain allocation manner is specified, the frequency domain resource allocation is performed in the Type1 frequency domain allocation manner; if not, and the Type0 frequency domain allocation mode is designated, performing frequency domain resource allocation through the Type0 frequency domain allocation mode; if so, determining the actual PRB utilization rate, determining whether the actual PRB utilization rate is greater than or equal to a preset minimum PRB utilization rate, if so, allocating frequency domain resources for the current user in a Type0 frequency domain allocation mode, otherwise, allocating frequency domain resources for the current user in a Type1 frequency domain allocation mode. When the frequency domain resources are unsuccessfully allocated to the current user by using the Type1 frequency domain allocation mode, the frequency domain resources can be reallocated to the current user by using the Type0 frequency domain allocation mode.
