Description

一种频谱分配方法和设备本申请要求于 2012 年 08 月 27 日提交中国专利局、申请号为 201210307310.9、发明名称为 "一种基于认知无线电***的频谱分配方法和设备" 的中国专利申请的优先权，其全部内容通过引用结合在本申请中。技术领域 The present invention claims the Chinese patent application filed on August 27, 2012 by the Chinese Patent Office, Application No. 201210307310.9, entitled "A Method and Apparatus for Spectrum Allocation Based on Cognitive Radio System" Priority is hereby incorporated by reference in its entirety. Technical field

本发明涉及通信技术领域，尤其是涉及了一种频谱分配方法和设备。背景技术 The present invention relates to the field of communications technologies, and in particular, to a spectrum allocation method and apparatus. Background technique

无线通信频谱是宝贵的自然资源，随着无线通信技术的飞快发展，频谱资源贫乏的问题日益严重。为緩解频谱资源紧张的现状，通过对无线通信频谱进行监测和研究，发现某些频段（如电视频段）在大多数时间内并未使用或在大多数地域内并未使用。在这种情况下，出现了多系统多用户竟争该频段的情况。如果多个***具备使用该频段的资格和 / 或能力，则将该频段称为共享频段，将使用该共享频段的***称为共享频段***。 CR ( Cognitive Radio, 认知无线电） ***是共享频段***的一种。 CR的基本思想是：在不对授权***造成干扰的前提下， CR*** 可以通过监测当前无线环境的变化来动态的选择空白频段用于进行通信。 The wireless communication spectrum is a precious natural resource. With the rapid development of wireless communication technology, the problem of poor spectrum resources is becoming more and more serious. In order to alleviate the current situation of spectrum resources, by monitoring and researching the spectrum of wireless communication, it is found that certain frequency bands (such as TV bands) are not used for most of the time or are not used in most areas. In this case, there have been cases where multiple systems and multiple users compete for this band. If multiple systems are eligible and/or capable of using this band, the band is referred to as the shared band and the system using the shared band is referred to as the shared band system. The CR (Cognitive Radio) system is one of the shared frequency band systems. The basic idea of CR is: Under the premise of not causing interference to the authorization system, the CR system can dynamically select the white space for communication by monitoring the changes in the current wireless environment.

当 CR***机会性使用授权***的空白频段时，要保证授权***不会受到干扰。要保证授权***不会受到干扰，就需要 CR***准确判断出哪些授权***的频段是可用的空白频段（在这些频段上引入 CR*** 不会影响授权***的正常工作）。当 CR ***占用的频段不再可用时， CR***需要及时从该频段退出，并将这些频段归还给授权***。 When the CR system opportunistically uses the blank band of the authorization system, ensure that the authorized system is not subject to interference. To ensure that the authorization system is not subject to interference, the CR system needs to accurately determine which licensed system bands are available for the white space (the introduction of CR systems in these bands) Will not affect the normal operation of the authorization system). When the frequency band occupied by the CR system is no longer available, the CR system needs to exit from the band in time and return these bands to the authorization system.

目前，可以使用感知方法和数据库方法来确定空白频谱。在感知方法中， CR ***的基站设备通过感知算法在某频段上检测授权***的信号强度。当信号强度大于某门限值时，认为该基站设备距离使用该频段的授权***的距离过近。在此频段上引入 CR***会对授权***的工作产生影响，因此频段不可用。在数据库方法中， CR ***从本地数据库中获取某个具***置对应的可用频段的记录。 Currently, perceptual methods and database methods can be used to determine the white space spectrum. In the sensing method, the base station device of the CR system detects the signal strength of the authorized system on a certain frequency band through a perceptual algorithm. When the signal strength is greater than a certain threshold, the base station device is considered to be too close to the authorized system using the frequency band. The introduction of a CR system in this band will have an impact on the operation of the authorized system, so the band is not available. In the database method, the CR system obtains a record of the available frequency bands corresponding to a specific location from the local database.

目前，有如下***会使用空白频谱：蜂窝通信的室外网络（如 LTE ( Long Term Evolution,长期演进）室外网络），蜂窝通信的室内网络（如家庭基站小区）， Wi-Fi ( Wireless-Fidelity, 无线保真）网络， ad-hoc (点对点）网络，专用网络（如消防，医疗护等），智能仪表网络等。 At present, the following systems use white space spectrum: outdoor network for cellular communication (such as LTE (Long Term Evolution) outdoor network), indoor network for cellular communication (such as home base station cell), Wi-Fi (Wireless-Fidelity, Wireless fidelity network, ad-hoc (peer-to-peer) network, private network (such as fire protection, medical care, etc.), intelligent instrumentation network, etc.

如果多个***需要使用某空白频谱，当某一***使用该频谱时，该 ***通知周围其他***其正在使用该频普，以避免在***间 I起沖突。或者，该***在检测到该频谱没被使用时，立刻占用该频谱，若检测到该该频语被使用时则不占用该频语。 If multiple systems need to use a white space spectrum, when a system uses the spectrum, the system notifies other systems around it that it is using the frequency to avoid conflicts between systems. Alternatively, the system immediately occupies the spectrum when it detects that the spectrum is not being used, and does not occupy the frequency when it is detected that the frequency is used.

在现有技术中，任何共享频段***，例如， CR ***都可使用空白频谱。由于各共享频段***本身特点并不相同，各共享频段***在某频点上运行时带来的效果会存在差异。例如，如果共享频段***的用户数不多，业务量较小，该共享频段***使用空白频谱时的效率就会较低。共享频段***使用授权***的空白频段的目的是提高频谱利用率，并增大单位频谱单位时间内传输的数据量，但上述使用空白频谱的方式并不能有效地利用频谱。发明内容 In the prior art, any shared frequency band system, for example, a CR system, can use a white space spectrum. Since the characteristics of each shared frequency band system are not the same, the effects brought by each shared frequency band system when running at a certain frequency point may be different. For example, if the number of users in the shared band system is small and the traffic is small, the shared band system will be less efficient when using the white space spectrum. The purpose of the shared frequency band system using the blank band of the authorization system is to increase the spectrum utilization rate and increase the amount of data transmitted per unit time of the spectrum, but the above method of using the white space spectrum cannot effectively utilize the spectrum.

The technical solutions in the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the accompanying drawings. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

实施例一 Embodiment 1

针对现有技术中的问题，在考虑到以下情况后，本发明实施例一提供一种基于共享频段***的频谱分配方法。 In view of the problems in the prior art, the first embodiment of the present invention provides a spectrum allocation method based on a shared frequency band system after considering the following situations.

( 1 )各使用空白频谱的***的业务特性以及业务要求并不相同。例如： LTE室外网络需要同时满足多个用户通信，需要覆盖较大地理位置，基站等设备难以改变位置。 Wi-Fi 网络的接入点位置变化会更加灵活。专用网络的业务具有紧急且重要的特性，但一般数据量不会太大。进一步的，对于同一类型的网络，由于用户数的差异或者业务类型的差异，即使使用相同的频率资源， ***的吞吐量也会存在较大的不同。 (1) The service characteristics and service requirements of systems using white space spectrum are not the same. For example, an LTE outdoor network needs to meet multiple user communications at the same time, and needs to cover a large geographical location. It is difficult for a base station or the like to change its location. Access point location changes on Wi-Fi networks are more flexible. The business of a private network has urgent and important features, but the amount of data is generally not too large. Further, for the same type of network, the throughput of the system may vary greatly even if the same frequency resource is used due to the difference in the number of users or the difference in the type of service.

( 2 ) 不同***在布置网络时有一些参数需求，在一定的发射功率下，能够满足的覆盖范围是相对固定的，但是考虑到与授权***的共存，发射功率大的共享频段***需要的共存隔离需求较高，且可以使用某些空白的地理空间会相对减小。相反，发射功率小的共享频段***需要的共存隔离需求较低，且可以使用某些空白的地理空间就会相对大一些。 (2) Different systems have some parameter requirements when arranging the network, at a certain transmit power The coverage that can be satisfied is relatively fixed, but considering the coexistence with the authorization system, the shared frequency band system with large transmit power requires a higher coexistence isolation requirement, and the geospatial space in which some blanks can be used is relatively reduced. Conversely, a shared-band system with low transmit power requires less coexistence isolation and a relatively large geospatial space that can be used.

( 3 ) 为了对频谱资源进行合理调度，可以将调度单***资源的思路引入到多种不同***的动态频谱分配中，通过实时统计不同***的业务情况，在满足不同***需求的情况下，最大化地利用频谱。其中，同一***内的多用户调度以最大化地利用***吞吐量为目标，并确保不同业务流的 QoS ( Quality of Service, 服务质量）要求。调度算法包括：轮询算法（即循环调用每个用户，从调度概率上说，每个用户以同样的概率占用服务资源）、最大载干比算法（即只选择最大载干比的用户，使得信道条件最好的用户占用资源传输数据）、正比公平算法（在维持用户长期传输数据吞吐量大致公平的基础上，同时考虑利用短期信道变化情况增大传输效率）等。 (3) In order to properly schedule the spectrum resources, the idea of scheduling the system resources can be introduced into the dynamic spectrum allocation of different systems, and the service conditions of different systems can be statistically collected in real time to meet the requirements of different systems. Use the spectrum. Among them, multi-user scheduling within the same system aims to maximize system throughput and ensure QoS (Quality of Service) requirements for different traffic flows. The scheduling algorithm includes: a polling algorithm (ie, calling each user in a loop, from the scheduling probability, each user occupies the service resource with the same probability), a maximum carrier-to-interference ratio algorithm (ie, selecting only the user with the largest carrier-to-interference ratio, The user with the best channel condition occupies the resource transmission data), the proportional fair algorithm (based on maintaining the user's long-term transmission data throughput is fairly fair, and considering the use of short-term channel changes to increase the transmission efficiency).

本发明实施例一所提供的频谱分配方法中。图 1是本发明实施例一提供的一种基于共享频段***的频谱分配方法的流程示意图。如图 1所示，包括以下步骤： The spectrum allocation method provided in Embodiment 1 of the present invention. FIG. 1 is a schematic flow chart of a spectrum allocation method based on a shared frequency band system according to Embodiment 1 of the present invention. As shown in Figure 1, the following steps are included:

步骤 101 ,共享频段***向频语调度单元发送频谱资源申请消息（用于申请频谱资源），该频谱资源申请消息中至少携带该共享频段***对应的业务优先级。其中，对于多个共享频段***来说，各共享频段*** 均需要向频语调度单元发送频谱资源申请消息。 Step 101: The shared frequency band system sends a spectrum resource application message (for applying for a spectrum resource) to the frequency-speech scheduling unit, where the spectrum resource application message carries at least the service priority corresponding to the shared frequency band system. For multiple shared frequency band systems, each shared frequency band system needs to send a spectrum resource application message to the frequency language scheduling unit.

本发明实施例中，共享频段***对应的业务优先级可按照共享频段 ***的业务特点进行划分，且允许多种共享频段***对应同一业务优先级。例如，业务优先级的划分方式如下：对于消防和医疗救护等专用网络，考虑到业务紧迫性，相应共享频段***的业务优先级为最高级。对于蜂窝通信的室外网络，考虑到基站设备的大量投入，相应共享频段系统的业务优先级为次优先级。对于投入不高的网络，相应共享频段*** 的业务优先级更次之。又例如，还可根据政策或其他商业信息规定不同 ***的业务优先级。 In the embodiment of the present invention, the service priority corresponding to the shared frequency band system may be divided according to the service characteristics of the shared frequency band system, and multiple shared frequency band systems are allowed to correspond to the same service priority. For example, business priorities are divided as follows: For private networks such as fire and medical care, the business priority of the corresponding shared-band system is the highest, considering the urgency of the business. Correct In the outdoor network of cellular communication, considering the large amount of investment of the base station equipment, the service priority of the corresponding shared frequency band system is the secondary priority. For networks with low investment, the service priority of the corresponding shared frequency band system is second. As another example, business priorities for different systems can also be specified based on policies or other business information.

本发明实施例中，该频谱资源申请消息中还可携带以下内容之一或任意组合： *** ID (为申请频谱资源的共享频段***的标识，可由接入 ***标识，核心网 ID , 小区 ID组成，且*** ID及业务优先级与编号的对应关系可由协议规定）；位置信息（为申请频谱资源的共享频段*** 的小区位置及覆盖范围需求）；单位频谱资源能够达到的吞吐量（为申请频谱资源的共享频段***进行统计的，统计方式与当前统计方式类似）；需求频谱资源的特征，包括需求频谱资源的信道带宽、信道个数、是否连续、推荐频道（即共享频段***根据自身属性推荐本***优先支持的频道）等以及最大发射功率。 In the embodiment of the present invention, the spectrum resource application message may further carry one or any combination of the following contents: a system ID (identity of a shared frequency band system for applying for a spectrum resource, which may be identified by an access system identifier, a core network ID, and a cell ID) And the correspondence between the system ID and the service priority and the number can be specified by the protocol); the location information (the cell location and the coverage requirement of the shared frequency band system for applying the spectrum resource); the throughput that can be achieved by the unit spectrum resource (for the applied spectrum) The shared frequency band system of the resource is statistically calculated. The statistical method is similar to the current statistical method. The characteristics of the required spectrum resource include the channel bandwidth of the required spectrum resource, the number of channels, whether it is continuous, and the recommended channel (ie, the shared frequency band system is recommended according to its own attributes). The system preferentially supports the channel) and the maximum transmit power.

本发明实施例的一种优选实施方式中，频谱资源申请消息中携带的内容可以如表 1所示。 In a preferred implementation manner of the embodiment of the present invention, the content carried in the spectrum resource application message may be as shown in Table 1.

表 1 Table 1

步骤 102, 频语调度单元分别接收来自多个共享频段***的频谱资源申请消息，该频谱资源申请消息中至少携带共享频段***对应的业务优先级。 Step 102: The frequency-speech scheduling unit receives a spectrum resource application message from a plurality of shared frequency band systems, where the spectrum resource application message carries at least a service priority corresponding to the shared frequency band system.

步骤 103, 频语调度单元利用各共享频段***对应的业务优先级以及可用空白频谱资源为各共享频段***分配频谱资源。本发明实施例中，频语调度单元利用各共享频段***对应的业务优先级以及可用空白频谱资源为各共享频段***分配频谱资源，具体包括但不限于：频语调度单元利用各共享频段***对应的业务优先级将各共享频段***进行排序，并根据业务优先级从高到低的顺序将各共享频段 ***放入调度序列，以及利用可用空白频谱资源（频语调度单元通过读取存有空白频谱信息的数据库或者通过自身的感知学习等方式，获得可用空白频谱资源，且在此过程中还可以获取各可用空白频谱资源上允许的干扰功率值 )依次为调度序列中的各共享频段***分配频谱资源。 Step 103: The frequency language scheduling unit allocates spectrum resources to each shared frequency band system by using the service priority corresponding to each shared frequency band system and the available white space spectrum resources. In the embodiment of the present invention, the frequency language scheduling unit allocates spectrum resources to each shared frequency band system by using the service priority corresponding to each shared frequency band system and the available white space spectrum resources, including but not limited to: the frequency language scheduling unit uses each shared frequency band system correspondingly. The service priority classifies each shared frequency band system, and puts each shared frequency band system into a scheduling sequence according to the order of priority of the service, and utilizes the available white space spectrum resources (the frequency language scheduling unit reads the blanks by reading The spectrum information database obtains the available blank spectrum resources by means of its own cognitive learning, and in the process, the interference power values allowed on each available white space spectrum resource can also be obtained, and the shared frequency band systems in the scheduling sequence are sequentially allocated. Spectrum resources.

本发明实施例的一种优选实施方式中，上述频谱资源申请消息中还可以至少携带共享频段***所对应的单位频谱资源能够达到的吞吐量、需求频谱资源的信道带宽、覆盖范围、以及最大发射功率等信息；基于此信息，在将各共享频段***放入调度序列的过程中，还可以包括以下步骤： In a preferred embodiment of the present invention, the foregoing spectrum resource application message may further include at least a throughput that can be achieved by a unit spectrum resource corresponding to the shared frequency band system, a channel bandwidth of the required spectrum resource, a coverage range, and a maximum transmission. Information such as power; based on this information, in the process of putting each shared frequency band system into the scheduling sequence, the following steps may also be included:

当有不同共享频段***对应有相同的业务优先级时，频语调度单元利用不同共享频段***对应的单位频谱资源能够达到的吞吐量将不同共享频段***进行排序，并根据单位频谱资源能够达到的吞吐量从大到小的顺序将不同共享频段***放入调度序列；当有不同共享频段***对应有相同的单位频谱资源能够达到的吞吐量时，执行后续步骤，否则结束此过程； When different shared frequency bands have the same service priority, the frequency scheduling unit uses the throughput that can be achieved by the unit spectrum resources corresponding to different shared frequency bands to sort different shared frequency bands, and can be achieved according to the unit spectrum resources. When the throughput is from large to small, the different shared frequency band systems are put into the scheduling sequence; when different shared frequency bands have corresponding throughputs that can be achieved by the same unit spectrum resource, the subsequent steps are performed, otherwise the process ends;

频谱调度单元利用不同共享频段***对应的需求频谱资源的信道带宽将不同共享频段***进行排序，并根据需求频谱资源的信道带宽从小到大的顺序将不同共享频段***放入调度序列；当有不同共享频段系统对应有相同的需求频谱资源的信道带宽时，执行后续步骤，否则结束此过程； The spectrum scheduling unit uses different channel bandwidths of the required spectrum resources corresponding to the shared frequency band system to sort different shared frequency band systems, and puts different shared frequency band systems into the scheduling sequence according to the channel bandwidth of the required spectrum resources from small to large; When the shared frequency band system corresponds to the channel bandwidth of the same required spectrum resource, perform the following steps, otherwise the process ends;

频语调度单元利用不同共享频段***对应的（覆盖范围 /最大发射功率）为不同共享频段***进行排序，并根据（覆盖范围 /最大发射功率）从大到小的排序结果将不同共享频段***放入调度序列。 The frequency language scheduling unit uses different shared frequency band systems (coverage/maximum transmit work) Rate) Sorts the different shared-band systems and places different shared-band systems into the scheduling sequence according to the sorting result (coverage/maximum transmit power) from large to small.

本发明实施例的一种优选实施方式中，在将各共享频段***放入调度序列的过程中还可包括以下过程：当有共享频段***已经超过 N 次 (根据实际经验设置， N是大于等于 1的正整数）没有被分配频谱资源时，频语调度单元将该共享频段***放入调度序列的第一位；或，在收到共享频段***的频谱资源申请消息后，如果频语调度单元在时间 T(根据实际经验设置， Τ是整数）内没有为共享频段***分配频谱资源，则频语调度单元将该共享频段***放入调度序列的第一位。 In a preferred implementation manner of the embodiment of the present invention, the following process may be included in the process of placing each shared frequency band system into the scheduling sequence: When there is a shared frequency band system that has exceeded N times (according to actual experience, N is greater than or equal to When a positive integer of 1 is not allocated a spectrum resource, the frequency scheduling unit puts the shared frequency band system into the first position of the scheduling sequence; or, after receiving the spectrum resource application message of the shared frequency band system, if the frequency scheduling unit At time T (set according to actual experience, Τ is an integer), no spectrum resource is allocated for the shared frequency band system, and the frequency scheduling unit puts the shared frequency band system into the first position of the scheduling sequence.

本发明实施例中，基于调度序列的排序结果，频语调度单元可以为各共享频段***选取合适的频谱资源，直至将频谱资源划分完毕；在频谱调度单元利用可用空白频谱资源依次为调度序列中的各共享频段系统分配频谱资源的过程中，对于调度序列中当前待分配频谱资源的共享频段***（以 CRSx为例进行后续说明 ), 其频谱分配方式包括： In the embodiment of the present invention, based on the scheduling result of the scheduling sequence, the frequency scheduling unit may select an appropriate spectrum resource for each shared frequency band system until the spectrum resource is divided; and the spectrum scheduling unit uses the available white space spectrum resource as the scheduling sequence. In the process of allocating spectrum resources in the shared frequency band system, for the shared frequency band system of the current spectrum resource to be allocated in the scheduling sequence (using CRSx as an example for subsequent description), the spectrum allocation manner includes:

频语调度单元获得满足 CRSx所需信道带宽（频谱资源申请消息中携带）要求的频段，并按带宽由窄到宽的顺序排列；之后从获得的频段中选取对应有最小带宽的频段，并判断当 CRSx在选取的频段上工作时， CRSx是否与当前工作在其他频段上的授权***和共享频段***共存；如果 CRSx与当前工作在其他频段上的授权***和共享频段***共存，则频语调度单元将选取的频段分配给 CRSx; 如果 CRSx与当前工作在其他频段上的授权***和 /或共享频段***不共存，则频语调度单元从获得的频段中选取对应有次小带宽的频段进行判断，一直到为 CRSx分配频段或者没有频段分配给 CRSx。 The frequency-scheduled scheduling unit obtains the frequency bands required to meet the required channel bandwidth (carrying in the spectrum resource application message) of the CRSx, and arranges the bandwidths in a narrow to wide order; then selects the frequency band corresponding to the minimum bandwidth from the obtained frequency bands, and determines When CRSx works in the selected frequency band, does CRSx coexist with the authorized system and shared band system currently working in other frequency bands; if CRSx coexists with the authorized system and shared band system currently working in other frequency bands, frequency scheduling The unit allocates the selected frequency band to the CRSx; if the CRSx does not coexist with the authorized system and/or the shared frequency band system currently working in other frequency bands, the frequency scheduling unit selects the frequency band corresponding to the second smallest bandwidth from the obtained frequency bands to determine , until the band is allocated for CRSx or no band is assigned to CRSx.

步骤 B、频语调度单元分配频谱资源。 Step B: The frequency scheduling unit allocates spectrum resources.

( 1 )进行调度序列排序：频谱调度单元收到来自 CRSl , CRS2和 CRS3的频谱资源申请消息，按照 CRSl , CRS2和 CRS3的业务优先级，可以得出 CRS3>CRS1=CRS2, CRS3进入调度序列的第一位；由于 CRS1 和 CRS2的业务优先级相同，比较 CRS1和 CRS2的单位频谱资源能够达到的吞吐量； CRS1和 CRS2的单位频谱资源能够达到的吞吐量相同，比较 CRS1和 CRS2的需求频谱资源的信道带宽； CRS1和 CRS2的需求频谱资源的信道带宽相同，比较 CRS1和 CRS2的覆盖范围和 /或最大发射功率）；由于 CRS1的覆盖范围和 /或最大发射功率）大于 CRS2的覆盖范围和 /或最大发射功率，因此 CRS1 进入调度序列的第二位， CRS2 进入调度序列的第三位。 (1) Perform scheduling sequence ordering: The spectrum scheduling unit receives the spectrum resource application messages from CRS1, CRS2, and CRS3, and according to the service priorities of CRS1, CRS2, and CRS3, it can be found that CRS3>CRS1=CRS2, and CRS3 enters the scheduling sequence. First place; because CRS1 and CRS2 have the same service priority, compare the throughput that CRS1 and CRS2 can achieve by unit spectrum resources; CRS1 and CRS2 can achieve the same throughput per unit spectrum resource, compare CRS1 and CRS2 demand spectrum resources Channel bandwidth; CRS1 and CRS2 require the same spectrum bandwidth of the spectrum resources, compare the coverage and/or maximum transmit power of CRS1 and CRS2); the coverage and/or maximum transmit power of CRS1 is greater than the coverage of CRS2 Cover range and / or maximum transmit power, so CRS1 enters the second bit of the scheduling sequence and CRS2 enters the third bit of the scheduling sequence.

( 2)频谱调度单元通过访问数据库获知， CRS1, CRS2 和 CRS3 所处的地理位置存在差异， CRS3 所处的地理区域当前可用的空白频段为 f2, f3, f4; 其他正在被使用的频段有 fl, fl上承载 TV授权***；其中 f2提供 8M带宽，当前无其他***， f3提供 8M带宽，当前无其他 ***， f4提供 4M带宽，当前无其他***； CRS1及 CRS2所处的地理区域当前可用的空白频段为 f2, f3, 其他正在被使用的频段有 fl, fl上承载 TV授权***；其中 f2提供 8M带宽，当前无其他***， f3提供 8M 带宽，当前无其他***。 (2) The spectrum scheduling unit knows that the geographical locations of CRS1, CRS2 and CRS3 are different by accessing the database. The currently available white space in the geographical area where CRS3 is located is f2, f3, f4; other frequency bands being used are fl , fl carries the TV authorization system; f2 provides 8M bandwidth, there is no other system at present, f3 provides 8M bandwidth, there is no other system at present, f4 provides 4M bandwidth, there is no other system at present; the geographic area where CRS1 and CRS2 are currently available is currently available. The blank frequency band is f2, f3. Other frequency bands that are being used have fl, fl on the TV authorization system; f2 provides 8M bandwidth, there is no other system at present, f3 provides 8M bandwidth, and there is no other system at present.

( 3 )根据调度序列的顺序，频谱调度单元为各 CRS分配资源。 a、根据提供的带宽大小，得到频段为 f4, f2, f3。 (3) According to the order of the scheduling sequence, the spectrum scheduling unit allocates resources for each CRS. a. According to the provided bandwidth, the frequency bands are f4, f2, and f3.

b、当应用 f4中的 4M带宽承载 CRS3时，判断 CRS3与 fl上的授权***是否满足邻频共存准则，若满足，则可以将 f4频段上的 4M分配给 CRS3; 若不满足，则需要判断其他频段是否符合。 b. When the 4M bandwidth in the application f4 carries the CRS3, it is determined whether the authorization system on the CRS3 and the fl-conditions meets the coexistence criterion of the adjacent frequency. If yes, the 4M in the f4 frequency band can be allocated to the CRS3; if not, the judgment is required. Whether other bands are met.

c、 4 设为 CRS3分配的资源为 f4上的 4M,此时为 CRS1分配资源； CRS1可用的频段为 f2, f3, 当应用 f2上的 5M带宽承载 CRS1时，判断 CRS1与 fl上的授权***是否满足邻频共存准则，若满足，判断 CRS1 与 f4上的 CRS3是否满足邻频共存准则，若满足，则将 fl上的 5M带宽分配给 CRS1; 若上述两步判断中任一不满足，判断 f3承载 CRS1时是否满足与授权***以及 CRS3的邻频共存，若满足，则进行分配，若不满足，则无法为 CRS1分配资源。 c. 4 The resource allocated to CRS3 is 4M on f4, and the resource is allocated for CRS1. The available frequency band of CRS1 is f2, f3. When the 5M bandwidth on the f2 is used to carry CRS1, the authorization system on CRS1 and fl is judged. Whether the adjacent frequency coexistence criterion is satisfied, and if it is satisfied, whether the CRS3 on CRS1 and f4 satisfies the adjacent frequency coexistence criterion, and if yes, allocates the 5M bandwidth on fl to CRS1; if any of the above two steps is not satisfied, judge Whether f3 carries CRS1 and coexists with the adjacent system of the authorized system and CRS3. If it is satisfied, the allocation is performed. If it is not satisfied, resources cannot be allocated for CRS1.

在判断邻频共存时，以 f2上承载 CRS1, 判断与 f4上承载 CRS3是否满足邻频共存为例，其具体实现方式如下：频语调度单元根据 CRS1 及 CRS3上报的地理位置信息，计算两个基站设备之间的距离 Dcr; 判断当 CRS1使用 f2, CRS3使用 f4, 距离 Dcr是否满足邻频共存准则；进一步，异***间邻频共存时最严重的干扰位于两个基站设备之间，假设 CRS1的基站设备干扰 CRS3的基站设备时， CRS3正常工作所需的距离隔离度为 Dl , CRS3的基站设备干扰 CRS1的基站设备时， CRS1正常工作所需的距离隔离度为 D2,邻频共存准则为 Dcr>MAX ( Dl , D2 ), 邻频共存准则涉及的距离隔离可由互干扰仿真得到。 When judging the coexistence of the adjacent frequencies, the CRS1 is carried on the f2, and it is determined that the CRS3 on the f4 satisfies the adjacent frequency coexistence as an example. The specific implementation manner is as follows: The frequency scheduling unit calculates two according to the geographical location information reported by CRS1 and CRS3. Distance between base station devices Dcr; When CRS1 uses f2 and CRS3 uses f4, whether the distance Dcr satisfies the adjacent frequency coexistence criterion; further, the most serious interference between the inter-system adjacent frequency coexistence is located between two base station devices, assuming that the base station device of CRS1 interferes with the CRS3 base station device The distance isolation required for the normal operation of the CRS3 is D1. When the base station equipment of the CRS3 interferes with the base station equipment of the CRS1, the distance isolation required for the normal operation of the CRS1 is D2, and the adjacent frequency coexistence criterion is Dcr>MAX (Dl, D2). The distance isolation involved in the adjacent frequency coexistence criterion can be obtained by mutual interference simulation.

d、假设为 CRS1分配的资源为 f2上的 5M带宽， CRS2可用的频段为 f3,在为 CRS2进行频谱分配时，当应用 f23上的 5M带宽承载 CRS2 时，需要判断 CRS2与 fl上授权***是否满足邻频共存准则，若满足，判断 CRS2与 f4上的 CRS3是否满足邻频共存准则，若满足，判断 CRS2 与 f2上的 CRS1是否满足邻频共存准则，若满足，将 f3上的 5M带宽分配给 CRS2; 若上述两步判断任一不满足，则无法为 CRS2分配资源。 d. It is assumed that the resource allocated for CRS1 is the 5M bandwidth on f2, and the frequency band available for CRS2 is f3. When the spectrum allocation for CRS2 is applied, when the 5M bandwidth on the f23 is used to carry CRS2, it is necessary to determine whether the CRS2 and the authorized system on the fl The adjacent frequency coexistence criterion is met. If yes, it is determined whether the CRS3 on CRS2 and f4 satisfies the adjacent frequency coexistence criterion. If yes, it is determined whether CRS1 on CRS2 and f2 satisfies the adjacent frequency coexistence criterion, and if satisfied, the 5M bandwidth allocation on f3 is satisfied. For CRS2; if any of the above two steps is not satisfied, then resources cannot be allocated for CRS2.

步骤 C、频语调度单元将分配的频谱资源的信息发送给共享频段系统。 Step C: The frequency scheduling unit sends the information of the allocated spectrum resource to the shared frequency band system.
