Description

一种确定发射功率的方法、装置及*** 技术领域 Method, device and system for determining transmission power

本发明涉及无线通信领域，尤其涉及一种确定发射功率的方法、装置及系统。背景技术 The present invention relates to the field of wireless communications, and in particular, to a method, apparatus, and system for determining transmit power. Background technique

随着无线电技术的不断进步，各种各样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，频谱资源表现出极为紧张的局面；而另一方面在传统的固定频谱分配模式下，频谱资源的利用率却不高。从某种意义上讲，是这种固定分配给授权***的频谱分配制度造成了频谱资源极为紧张的局面。而认知无线电技术就打破了传统意义上的频谱固定分配制度，将频语在***间动态分配，提高了频谱的利用效率。 With the continuous advancement of radio technology, a variety of radio services have emerged, and the spectrum resources supported by the radio service are limited. In the face of increasing demand for bandwidth, spectrum resources are extremely tight; On the other hand, in the traditional fixed spectrum allocation mode, the utilization of spectrum resources is not high. In a sense, this spectrum allocation system that is fixedly assigned to the authorization system creates a situation in which the spectrum resources are extremely tight. Cognitive radio technology breaks the fixed spectrum allocation system in the traditional sense, dynamically allocates frequency between systems, and improves the efficiency of spectrum utilization.

标准讨论中引入了地理位置信息数据库（ Geo-location database )或数据库 ( DB , Data Base )。该 DB负责对主***的保护，即根据主***干扰保护原则要求，对空闲频谱用户设备或次级***用户设备 ( WSD , White Space Device ) 的运行参数做出限制，从而保证主***不受干扰，上面所述的问题也被称作主次***间共存问题；又由于多个次级***的存在，在借用主***空闲频谱资源时，数据库只能保证多个次级***用户设备累加干扰满足主次***共存条件，但并不负责次级***之间的频谱分配，及彼此间干扰共存问题。因此标准讨论中又引入了另一逻辑实体——频谱协调器（SC, Spectrum Coordinator )或共存实体，该逻辑实体用于解决上面提到的次级***间自共存问题，即通过限制次级***的发射参数，实现多个次级***用户设备的共存。 A geo-location database or a database (DB, Data Base) was introduced in the standard discussion. The DB is responsible for the protection of the primary system, that is, the operating parameters of the idle spectrum user equipment or the secondary system user equipment (WSD, White Space Device) are restricted according to the requirements of the primary system interference protection principle, thereby ensuring that the primary system is not interfered. The problem described above is also called the co-existence problem between the primary and secondary systems; and because of the existence of multiple secondary systems, when borrowing the idle spectrum resources of the primary system, the database can only ensure that the interference of multiple secondary system user equipments is satisfied. The primary and secondary systems coexist, but are not responsible for the spectrum allocation between the secondary systems and the problem of interference coexistence with each other. Therefore, another logical entity, the SC (Spectrum Coordinator) or a coexistence entity, is introduced in the standard discussion. The logic entity is used to solve the above-mentioned secondary system self-coexistence problem, that is, by limiting the secondary system. The transmission parameters enable the coexistence of multiple secondary system user equipment.

WSD的发射功率限制将由两者共同确定， WSD使用参数的确定需要先后经过 Geo-location DB , SC的两次计算：计算 1 , 计算 2; 其中， The transmission power limit of WSD will be determined by both. The determination of WSD usage parameters needs to be calculated twice by Geo-location DB and SC: calculation 1 , calculation 2;

计算 1为地理位置信息数据库才艮据 WSD的位置信息，选出其所在位置上的空闲频语 ( WS ), 然后基于主用户的保护准则在所有所述 WS上为该 WSD 分别计算最大发射功率限制，形成 WS列表，在运行参数 1消息中发送给 SC; 当存在多个 WSD时，地理位置信息数据库考虑多个 WSD的累加干扰满足主用户保护准则，给出每个 WSD的最大发射功率限制值； Calculate 1 as the geographic location information database, according to the location information of WSD, select its location Idle Frequency (WS), then calculate the maximum transmit power limit for the WSD on all of the WSs based on the primary user's protection criteria, forming a WS list, sent to the SC in the Run Parameter 1 message; when there are multiple WSDs When the geographic location information database considers that the accumulated interference of multiple WSDs satisfies the primary user protection criterion, the maximum transmit power limit value of each WSD is given;

计算 2为 SC做进一步的 WSD间协调管理（包括共存，优先级分配等原则），在 DB提供的 WS列表中选择部分 WS, 并调整选出 WS的发射参数限制使之满足 WSD间共存要求，形成新的 WS列表，在运行参数 2消息中发送给 WSD。 Computation 2 is the SC for further coordinated management of WSD (including coexistence, priority allocation, etc.), select part of WS in the WS list provided by DB, and adjust the transmission parameter limit of WS to meet the WSD coexistence requirement. A new WS list is formed and sent to the WSD in the Run Parameter 2 message.

在上述流程中，两次计算依据的原则不同，但先后顺序是确定的，因此在计算 1中，由于没有考虑计算 2中所涉及的原则，而出现计算 1中对某些 WS 的发射参数限制计算成为了无用计算，即计算 1针对 WSD位置上的所有 WS 都会分别计算发射参数限制，但 SC根据共存及优先级分配原则将排除其中的一部分 WS, 计算 1对于这部分 WS的发射参数限制计算就是无用计算；另夕卜，当存在多个 WSD时，在满足主用户保护的前提下，所述多个 WSD的发射功率组合有很多种， Geo-location DB出于主用户保护的原则为 WSD做的功率分配，并不一定能符合次级***设备的意愿。发明内容 In the above process, the principles of the two calculations are different, but the order is determined. Therefore, in calculation 1, the emission parameter limits for some WS in calculation 1 occur because the principles involved in calculation 2 are not considered. The calculation becomes useless calculation, that is, calculation 1 calculates the emission parameter limit for all WSs at the WSD position, but the SC will exclude some of the WS according to the coexistence and priority allocation principle, and calculate 1 for the transmission parameter limit calculation of this part of WS. In other words, when there are multiple WSDs, under the premise of satisfying the protection of the primary user, there are many combinations of transmission powers of the multiple WSDs, and the Geo-location DB is WSD for the principle of primary user protection. The power distribution done does not necessarily meet the wishes of the secondary system equipment. Summary of the invention

有鉴于此，本发明的目的在于提供一种确定发射功率的方法、装置及***，能实现***整体优化，减少了***整体计算量；最终确定的可用频谱及发射功率限制能够满足次级***的频谱分配意愿。 In view of this, an object of the present invention is to provide a method, device and system for determining transmit power, which can optimize the overall system and reduce the overall calculation amount of the system; the finally determined available spectrum and transmit power limit can satisfy the secondary system.

这里，所述部分设备参数包括：天线位置（东经 54.2度，北纬 67度），定位精度（ 100m ) , 设备类型（Fixed WSD ) ；发送给 DB的目的是： DB 据此信息来确定该 WSD所在位置上的空闲频谱信息。 Here, the partial device parameters include: antenna position (54.2 degrees east longitude, 67 degrees north latitude), positioning accuracy (100m), device type (Fixed WSD); the purpose of sending to the DB is: DB Based on this information, the free spectrum information at the location of the WSD is determined.

步骤 603: DB确定 WSD1所在位置的空闲频谱。 Step 603: The DB determines the idle spectrum of the location where WSD1 is located.

具体的： DB基于 WSD1的位置，查找 TV***频语使用情况，存在 TV ***在该区域上未使用的 TVWS资源包括： {频语 25、 30、 34、 40、 45、 46、 50}。 Specifically: The DB searches for the frequency usage of the TV system based on the location of the WSD1. The TVWS resources that are not used by the TV system in the area include: {frequency words 25, 30, 34, 40, 45, 46, 50}.

步骤 604: DB向 SC反馈空闲频谱列表，及各个空闲频语对应的主用户保护相关信息。 Step 604: The DB feeds back to the SC the idle spectrum list and the primary user protection related information corresponding to each idle frequency.

具体的，查找该 WSD1 所在位置区域内及相邻区域内现有 WSD 的 TVWS 频语使用情况，分析共存需求； WSD1 附近存在 3 个 WSD工作在 TVWS资源上，分别为： WSD2、 WSD3、 WSD4。 Specifically, find the TVWS frequency usage of the existing WSD in the location area of the WSD1 and the adjacent area, and analyze the coexistence requirement; there are three WSDs working on the TVWS resources near WSD1, namely: WSD2, WSD3, WSD4.

具体信息如下表所示: The specific information is shown in the following table:

sc利用自由空间传播模型，如下式所示：

Sc uses the free space propagation model as shown below:

PL = 20 - !ogi O(f ) 4 20 * iGg(O) + 32.4 PL = 20 - !ogi O(f ) 4 20 * iGg(O) + 32.4

其中 fp为中心频率， D为隔离距离； Where fp is the center frequency and D is the isolation distance;

计算上述 3个 WSD与 WSD1之间的干扰关系（这里需要根据 WSD1 的类型来假定其发射功率，本实施例中假定 WSD1发射功率为 40dBm ) , 确定彼此间的频域隔离距离。 The interference relationship between the above three WSDs and WSD1 is calculated (here, the transmit power is assumed according to the type of WSD1, and the WSD1 transmit power is assumed to be 40 dBm in this embodiment), and the frequency domain isolation distance between each other is determined.

以 WSD2与 WSD1为例：两设备的位置是固定的， WSD2 以上表中的工作参数进行工作， WSD1以假定的发射功率发射，在各自的发射模板下，计算满足各自小区预置性能需求（如吞吐量等）时，所需频域隔离的距离，得出：（这种计算过程也可以根据经验值的积累得到）。 Take WSD2 and WSD1 as examples: The location of the two devices is fixed. The working parameters in the above table of WSD2 work. WSD1 transmits with the assumed transmit power. Under the respective transmit template, the calculation meets the preset performance requirements of the respective cells (such as When throughput, etc.), the required distance in the frequency domain is isolated: (This calculation process can also be based on the accumulation of empirical values).

WSD2与 WSD1 间频域隔离距离为两个 TV频谱，即 WSD2所使用的 TV频谱 34及其第一邻道不能为 WSD1所用， TV频语 33,34,35对于 WSD1 为禁用频谱； The frequency separation between WSD2 and WSD1 is two TV spectrums, which is used by WSD2. TV spectrum 34 and its first adjacent channel cannot be used by WSD1, and TV frequency 33, 34, 35 is disabled spectrum for WSD1;

WSD3与 WSD1 间的频域隔离距离为 1个 TV频谱，即不同频即可， WSD3所使用的频谱 40对于 WSD1为禁用频谱； The frequency separation between WSD3 and WSD1 is 1 TV spectrum, that is, different frequency. The spectrum 40 used by WSD3 is disabled for WSD1.

WSD4同样保证不同频即可，即频语 45对于 WSD1为禁用频语。 WSD4 also guarantees different frequencies, that is, frequency 45 is disabled for WSD1.

因此，共存需求为： WSD1禁用频语： 33、 34、 35、 40、 45。 Therefore, the coexistence requirements are: WSD1 disables the frequency: 33, 34, 35, 40, 45.

得到 WSD1的可用频语为频语： 25、 30、 46、 50。 The available frequency of WSD1 is frequency: 25, 30, 46, 50.

针对上面 4个可用频谱，分别计算最大允许发射功率限制，计算公式及参数（其中主***相关参数存储在数据库中）解释如下： For the above four available spectrums, calculate the maximum allowable transmit power limit, and calculate the formula and parameters (where the main system related parameters are stored in the database) as explained below:

当保护信号级别与接收机灵敏度很接近时（即当 WSD运行接近广播覆盖边缘时） , 保护比还需要考虑接收机灵敏度衰落而包括 3dB的余量。 When the protection signal level is close to the receiver sensitivity (ie, when the WSD is operating close to the broadcast coverage edge), the protection ratio also needs to consider the receiver sensitivity fading to include a 3 dB margin.
