Technical field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method and apparatus for allocating a frequency spectrum.

Background technique

5G proposes a traffic growth target of 1000 times or more in the future, which requires more wireless mobile communication bands to meet the development needs of the wireless mobile communication market in 2020 and beyond. ITU-R (ITU-Radio communications sector) predicts that China's mobile communication frequency demand in 2020 is 1490-1810MHz, and the currently available available frequencies are usually on the order of hundreds of MHz.

At present, radio regulation mainly adopts a fixed frequency allocation policy. On the one hand, new frequency demands are constantly emerging, and it is difficult for wireless systems to allocate the required spectrum resources. On the other hand, the allocated spectrum resources are not utilized at a high rate, and there is a high degree of frequency usage imbalance. It is necessary to carry out more flexible frequency use techniques and policy research to improve the efficiency of frequency utilization.

Spectrum sharing technology is a promising approach to intelligent frequency utilization. In addition to the technical need for continuous research and improvement, it is also necessary to consider the use of radio frequencies and the adjustment and changes of regulatory rules.

The current state of spectrum use is that future demand far exceeds available resources, and spectrum sharing combined with newly planned spectrum can more effectively guarantee the demand for future high spectral efficiency and high rate. Due to the uneven distribution of users in different areas and times, the load of different operators' access networks varies in time and space, so there is a difference in the demand for spectrum. The static spectrum allocation strategy enables the access networks of different operators to dynamically adjust the occupied spectrum resources according to the change of the network load, thereby causing the spectrum resources not being fully utilized and the spectrum to be over-saturated.

In the prior art, there is no solution for multi-operator spectrum sharing. For spectrum sharing between multiple systems (such as multi-RAT (Radio Access Type) within the carrier), and spectrum sharing between the cognitive radio system and other host systems, it is basically based on accessing the database or the physical layer. Spectrum-aware technology enables shared spectrum resources to be shared between systems and cannot meet the spectrum sharing of multiple operators.

In summary, there is currently no solution for spectrum allocation for multi-operator spectrum sharing scenarios.

All other embodiments obtained by those skilled in the art based on the embodiments in the present disclosure are within the scope of the present disclosure.

Among them, the sex price function factor in the embodiment of the present disclosure reflects the performance of the operator on the bandwidth used and the factor of the money situation paid.

The fairness factor reflects the publicity of the allocation of spectrum resources among the spectrum resource pools to multiple operators. Flat situation.

The correction factor reflects the correction of the spectrum bandwidth to be allocated by each operator, and also reflects the credibility of the operator to report the spectrum demand.

The spectrum allocation device of the embodiment of the present disclosure connects a plurality of operator devices to receive an operator's spectrum application, manages an available spectrum resource pool, and implements effective allocation of spectrum resources.

In an implementation, the spectrum allocation device in the embodiment of the present disclosure may be an advanced spectrum management unit in a centralized architecture, or a central management unit, or a database device, which is connected to an existing device of the operator (for example, a network management system). The function of the device).

The carrier device of the embodiments of the present disclosure may be an operator network management device and/or a base station.

As shown in FIG. 1, a system for allocating a spectrum according to Embodiment 1 of the present disclosure includes: a spectrum allocation device 10 and at least one carrier device 20.

The spectrum allocation device 10 is configured to determine an expected performance parameter value of each operator that needs to perform spectrum allocation on the requested bandwidth; and determine a sex price function factor of each operator according to the determined expected performance parameter value of each operator; The operator's price function factor and the spectrum allocation fairness factor and correction factor of each operator allocate spectrum to each operator from the currently available spectrum resources.

The operator equipment 20 is configured to report the required bandwidth to the spectrum allocation device, and perform spectrum allocation for the station managed by the spectrum allocation device 10 according to the spectrum allocated by the spectrum distribution device 10.

In an implementation, if the spectrum allocation device needs to perform spectrum allocation, the currently available spectrum resources may be counted, and a spectrum resource pool may be established. The spectrum in the resource pool may be discontinuous, fragmented, or unused. Let the total bandwidth of the resource pool be the Band _pool .

It is assumed that the spectrum center frequency used by each operator is f _n,now , and the bandwidth is Band _n,now , n=1,...,N, where N is the number of operators. Here, there may be carriers of the same frequency between the bandwidths of the operators, but at this time, the deployment of the same-frequency cells meets certain isolation requirements, for example, the geographical distance of the same-frequency cells meets certain requirements, or the propagation loss (including freedom) Space propagation, penetration of indoor buildings, etc.) meet certain requirements.

The spectrum allocation device performs the sampling monitoring of the actual use of the spectrum during the use of the allocated spectrum resources by the operators, that is, periodically or irregularly, the monitoring message is sent for the spectrum allocation device to obtain the current load from the operator equipment. , resource occupancy rate, number of users accessing the network, and so on. After receiving the supervision message, the carrier device reports its current buffer (cache) traffic and resources. Usage rate, number of access users, etc.

When the operator needs to change the spectrum bandwidth, the operator equipment can report the required bandwidth to the spectrum allocation device.

Optionally, the operator equipment may estimate the required bandwidth according to the current traffic volume of the statistical system buffer, the average resource utilization ratio of the system, and the like.

After the bandwidth allocation device receives the required bandwidth reported by the operator equipment, if the idle spectrum in the spectrum pool is sufficient to satisfy the sum of all reported required bandwidths, the operators are allocated bandwidths that meet the requirements in turn.

If the idle spectrum in the spectrum pool cannot meet the sum of all the reported bandwidth requirements, that is, the currently available spectrum resources cannot meet the sum of the bandwidth requirements currently applied by the operators that need to perform spectrum allocation, then the operators that need to perform spectrum allocation are determined. The expected performance parameter value on the applied bandwidth, and determining the price function factor of each operator according to the determined expected performance parameter values of each operator; according to the operator's price function factor and the spectrum allocation of each operator The fairness factor and the correction factor allocate spectrum to each operator from the currently available spectrum resources.

In the implementation, after the spectrum allocation device receives the required bandwidth reported by the operator equipment, it may not determine whether the idle spectrum in the spectrum pool can satisfy the sum of all the reported required bandwidths, but directly fails to meet all the reported bandwidth requirements. The sum is processed.

In the implementation, the spectrum allocation device has a plurality of ways to determine the expected performance parameter values of the operators on the applied bandwidth that need to be allocated for spectrum allocation, and several are listed below:

Manner 1: The spectrum allocation device receives the expected throughput or expected spectrum usage efficiency reported by each operator as the expected performance parameter value of each operator on the applied bandwidth.

Specifically, the operator equipment reports the expected throughput or expected spectrum usage efficiency to the spectrum allocation device.

If the expected spectrum usage efficiency is reported, the operator equipment can use the average resource occupancy rate within the set period of the previous period as the expected spectrum usage efficiency.

If the expected throughput is reported, the carrier equipment has two options for determining the expected throughput:

1. Determine the expected throughput based on the average data rate within the set length of the previous period, the bandwidth of the current application, and the average operating bandwidth within the set period of each operator's previous period.

Optionally, the expected throughput satisfies Equation 1:

Formula one.

The size of the previous period can be set according to the experience value, and the duration of the previous period of each operator can be the same or different.

2. The operator equipment reports the channel measurement of each frequency point through the terminal, and uses the existing scheduling algorithm to predict the terminal to be scheduled to be transmitted, and maps the channel quality reported by the terminal on the applied idle frequency band to the maximum available. The modulation and coding level, which in turn calculates the expected data rate based on the modulation and coding level, sums the data rates of all the intended to be scheduled terminals on the applied idle frequency band as the expected throughput.

Manner 2: The spectrum allocation device determines each operator according to an average data rate within a set period of time of each operator, a bandwidth currently applied by each operator, and an average working bandwidth within a set period of each operator's previous period. The throughput is expected, and the determined expected throughput of each operator is taken as the expected performance parameter value of each operator on the applied bandwidth.

Alternatively, the expected throughput satisfies Equation 1.

Mode 3: The spectrum allocation device uses the average resource occupancy rate of each operator for the set period of time in the previous period as the expected performance parameter value of each operator's applied bandwidth.

Optionally, the spectrum allocation device determines, according to the determined expected performance parameter value of each operator, the determined performance parameter value of each operator according to the determined performance parameter value of each operator and the spectrum resource reported by each operator. Use the quotation to determine the price function factor for each operator.

Correspondingly, the operator equipment reports the usage quotation of the spectrum resource to the spectrum allocation device together with the required bandwidth.

Among them, the sex price function factor can satisfy the formula 2.

TP _n =f(T _n ,price _n,new )=T _n ×price _n,new .........Formula 2.

Where TP _n is the price function factor of the operator n; T _n is the expected performance parameter value of the operator n; price _{n, new} is the usage quotation of the operator n.

The embodiment of the present disclosure determines the price function factor of each operator according to the spectrum quote of the operator, so as to ensure that the required bandwidth reported by the operator meets its current needs. If the operator The bandwidth for false reporting needs, although it can get more spectrum in the short term, but it has to pay more price.

In the implementation, the spectrum allocation device determines the spectrum allocation fairness factor of each operator according to any one of the following two ways:

Mode 1: The spectrum allocation fairness factor of each operator is the first statistical value of the spectrum resource occupancy of each operator. The larger the value, the higher the probability that the operator's allocated spectrum resources will meet their needs.

Specifically, the spectrum allocation device determines a spectrum allocation fairness factor of each operator according to the bandwidth allocated by each operator in the first M times and the bandwidth requirement of each of the first M times of each operator.

In the first method, the spectrum allocation fairness factor of each operator satisfies the formula 3:

Formula three.

Manner 2: The spectrum allocation fairness factor of each operator is the second statistical value of the spectrum resource occupancy of each operator. The larger the value, the longer the operator's occupation of the spectrum reference unit and the lower the probability that the spectrum will be idle.

Specifically, the spectrum allocation device determines a spectrum allocation fairness factor of each operator according to the time of the spectrum actually occupied by each operator in the first M times and the bandwidth allocated by each operator in the first M times;

Where M is a positive integer.

The spectrum allocation fairness factor of each operator in mode 2 satisfies formula 4:

Formula four.

In the embodiment of the present disclosure, the correction factor Be _n of each operator is adjusted and corrected based on the bandwidth requirement reported by the operator, based on the allocated bandwidth of the previous time and the actual performance of the system. At the same time, it can also characterize the operator's frequency application credibility. When the operator falsely reports more spectrum, it will not only pay more price, but if the actual performance (such as throughput, spectrum efficiency, etc.) is much different from the expected, then these will affect the next allocation. .

Optionally, the spectrum allocation device obtains a transmission rate of the current current buffer traffic reported by each operator according to the previous spectrum allocation and each monitoring message during the current spectrum allocation (transmission completes a packet divided by the used time) ), resource occupancy rate, number of access users, etc., calculate the correction factor.

Correspondingly, the operator equipment sends the current buffer traffic and/or the current PRB (physical resource block) resource occupancy rate to the spectrum allocation device after receiving the supervision message from the spectrum allocation device. .

There are two ways to do this:

Method 1: The transmission rate of the buffer traffic reported by each operator during the current spectrum allocation according to the previous spectrum allocation, and the number of times reported by each operator during the previous spectrum allocation to the current spectrum allocation period (ie, supervision occurs) The number of messages or the number of samples) and the expected throughput of each operator determine the correction factor for each operator.

The correction factor of each operator in mode 1 satisfies formula 5:

Formula V.

Manner 2: The transmission rate of the buffer traffic reported by each operator during the current spectrum allocation according to the previous spectrum allocation, the number of times reported by each operator during the previous spectrum allocation to the current spectrum allocation period, and each The operator's expected spectrum use efficiency determines the correction factor for each operator.

The correction factor of each operator in mode 2 satisfies formula 6:

Formula six.

The spectrum allocation device allocates a result for each operator's spectrum in the total available spectrum pool based on the current application bandwidth, combined with the weighting of the correction factor, the sex price function factor, and the fairness factor.

Allocating spectrum for each operator satisfies Equation 7:

Formula seven.

Combine the above formulas to get the formula eight:

Wherein, Band _pool spectrum total bandwidth that can be allocated; Band _{n, new} bandwidth carriers n demand; TP _n is a price-function factor carriers of n; T _n is the expected performance parameter values the operator of n;. Price _{n , new} is the use quote of the operator n; Be _n is the correction factor of the operator n; the fairness factor of the Occup _n operator n; Band _{i, new} is the bandwidth required by the operator i; TP _i is the sex of the operator i The price function factor; T _i is the expected performance parameter value of the operator i; price _{i, new} is the usage quote of the operator i; Be _i is the correction factor of the operator i; and the fairness factor of the Occup _i operator i.

The spectrum allocation device notifies each operator of the spectrum allocation result after determining the spectrum allocation result.

Correspondingly, after receiving the spectrum allocation result, the operator equipment performs resource scheduling and performs service transmission according to the new central frequency point and bandwidth.

The spectrum management node provided by the embodiment of the present disclosure sets the request confidence of each operator through sampling monitoring means to prevent false reporting of spectrum demand and low actual usage rate. When the actual performance or spectrum usage of the operator on the allocated spectrum is lower than expected, it will affect the next allocation. Combined with the price auction mechanism, although the false report can obtain more spectrum in the short term, it has to pay more price and thus play a balanced role. By establishing a multi-parameter objective function, the spectrum allocation result is closer to the actual use of the operator, avoiding waste of the spectrum and false reporting. Compared with the existing operators' independent spectrum licenses, it can be more effective The efficiency of the spectrum is improved, which is conducive to meeting the demand for high spectral efficiency and high rate in the future 5G.
