SC利用传播模型，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，以 WSD2与 WSD1为例考虑，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） The SC uses the propagation model to calculate the interference relationship between the above three WSDs and WSD1 (here, the transmission power is assumed according to the type of WSD1, and the WSD1 transmission power is assumed to be 40 dBm in this embodiment), and the frequency domain isolation distance between each other is determined. Taking 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 templates, the calculation meets the preset performance requirements of the respective cells. (such as throughput, etc.), the distance of the required frequency domain isolation, resulting in: (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信道，即 WSD2所使用的 TV 信道 34及其第一邻道不能为 WSD1所用， TV信道 33、 34、 35对于 WSD1 为禁用频谱； The frequency separation between WSD2 and WSD1 is two TV channels, that is, the TV channel 34 used by WSD2 and its first adjacent channel cannot be used by WSD1, and TV channels 33, 34, and 35 are disabled for WSD1;

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

WSD4同样保证不同频即可，即信道 45对于 WSD1为禁用频谱。 WSD4 also guarantees different frequencies, that is, channel 45 is disabled for WSD1.

因此，共存需求为： WSD1禁用信道： 33、 34、 35、 40、 45。步骤 303: SC向 DB发送 WS频谱申请消息，其中包含申请 WS资源的 WSD设备参数，及步骤 2分析中确定的 WSD1禁用信道信息；Therefore, the coexistence requirements are: WSD1 disable channels: 33, 34, 35, 40, 45. Step 303: The SC sends a WS spectrum application message to the DB, where the WSD device parameter for requesting the WS resource and the WSD1 disabled channel information determined in the step 2 analysis are included;

步骤 304: DB确定 WSD1的可用频谱；并计算每个可用频谱上的最大发射功率限制； Step 304: The DB determines the available spectrum of WSD1; and calculates a maximum transmit power limit on each available spectrum;

可用频谱的确定： 1、 DB基于 WSD1的位置，查找 TV系统频语使用情况，存在 TV系统在该区域上未使用的 TVWS资源包括： {信道 25、 30、 34、 40、 45、 46、 50}。 2、考虑共存需求禁用频谱为 {信道 33、 34、 35、 40、 45} , 因此， WSD1的可用频谱为： {信道 25、 30、 46、 50}。 Determination of the available spectrum: 1. 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: {channels 25, 30, 34, 40, 45, 46, 50 }. 2. Consider the coexistence requirement to disable the spectrum as {channels 33, 34, 35, 40, 45}. Therefore, the available spectrum of WSD1 is: {channels 25, 30, 46, 50}.

最大允许发射功率的计算：分别针对上述 4个可用信道进行计算，根据 WSD1 的设备参数，主系统用户设备保护准则，主系统用户设备信息，传播模型，釆用相关技术可以计算得出 WSD1在上述 4个可用信道上的最大允许发射功率限制值。计算公式及参数（其中主系统相关参数存储在数据库中）解释如下： (/J = f + M^s - /J- W + - MI- SiM+ <D + <D_rd - g, + L_fCalculation of the maximum allowable transmit power: Calculate for the above 4 available channels respectively, according to the WSD1 device parameters, the main system user equipment protection criteria, the main system user equipment information, the propagation model, and the relevant technology can calculate WSD1 in the above The maximum allowable transmit power limit value on the 4 available channels.

步骤 306: SC进行自共存处理； Step 306: The SC performs self-coexistence processing;

步骤 302在做共存需求分析时，对 WSD1的发射功率做了假定，即 WSD1 发射功率为 40dBm,从上表中可以看出，信道 30,从主系统用户保护的角度，其发射功率可以达到 50dBm,因此需要判断如果 WSD1在信道 30上以 50dBm 进行发射是否能满足 WSD间自共存需求，判断结果为不会对其他 WSD造成干扰； Step 302: In the coexistence demand analysis, the transmission power of WSD1 is assumed, that is, the transmission power of WSD1 is 40 dBm. As can be seen from the above table, the channel 30 can transmit 50 dBm from the perspective of user protection of the main system. Therefore, it is necessary to judge whether the WSD1 can transmit at 50 dBm on the channel 30 to satisfy the self-coexistence requirement between the WSDs, and the judgment result is that it does not cause interference to other WSDs;

步骤 307: 通过步骤 306的判断可知，无需对可用频谱列表作调整，因此， SC将上述可用频谱列表信息（运行参数）转发给 WSD1 ; Step 307: According to the judgment of step 306, it is not necessary to adjust the available spectrum list, so the SC forwards the above-mentioned available spectrum list information (operation parameter) to WSD1;

WSD1、 WSD2发出空闲频谱资源分配请求，共存需求为彼此间频域隔离限制时，每个 WSD可用频谱及发射功率限制确定的信令流程如图 4所示，下面对其#文详细说明： WSD1 and WSD2 send idle spectrum resource allocation requests. When the coexistence requirements are frequency domain isolation restrictions, the signaling flow determined by each WSD available spectrum and transmit power limit is shown in Figure 4.

步骤 401： WSD1、 WSD2向 SC发送 WS频谱资源申请，并提供设备参数，其中包括：天线位置（WSD1 : 东经 54.1度，北纬 67.5度； WSD2: 东经 54.2度，北纬 67度），定位精度（100m ) , 设备类型（ Fixed WSD ) , 设备辅射类型（频谱模板信息 ) ,技术标识（ LTE ) ,设备统一标识（如 FCC device ID ) , 天线高度（ 10m ) , 极化方式（水平极化），天线方向角（全向天线），天线俯仰角（25度）； Step 401: WSD1 and WSD2 send a WS spectrum resource request to the SC, and provide device parameters, including: antenna position (WSD1: 54.1 degrees east longitude, 67.5 degrees north latitude; WSD2: 54.2 degrees east longitude, 67 degrees north latitude), positioning accuracy (100m) ), device type (Fixed WSD), device auxiliary type (spectral template information), technical identification (LTE), device uniform identification (such as FCC device ID), antenna height (10m), polarization mode (horizontal polarization), Antenna direction angle (omnidirectional antenna), antenna pitch angle (25 degrees);

步骤 402: SC收到 WSD1、 WSD2的频谱资源申请后，查找该 WSD1、 WSD2所在位置区域内及相邻区域内除所述 WSD外的其他 WSD的 TVWS 频语使用情况，分析共存需求；Step 402: After receiving the spectrum resource application of WSD1 and WSD2, the SC searches for the WSD1. Analysis of coexistence requirements for TVWS frequency usage of WSDs other than the WSD in the location area of WSD2 and adjacent areas;

相关区域内并没有正在运行的 WSD设备，但由于 WSD1与 WSD2相距较近，彼此间存在共存问题： SC利用传播模型，计算上述 2个 WSD1与 WSD2 在各自位置上以预计的发射功率 40dBm进行发射时，两者间互不干扰的要求下，频域隔离的大小。得出两设备工作频谱中心频率的间隔为 24MHz ( TV 信道为 8MHz ) , 因此两设备工作频率的最小间隔为 3个 TV信道。 There are no running WSD devices in the relevant area, but because WSD1 is close to WSD2, there is a coexistence problem between them: SC uses the propagation model to calculate the above two WSD1 and WSD2 to transmit at the respective positions with the expected transmit power of 40dBm. When the two do not interfere with each other, the size of the frequency domain isolation. It is concluded that the center frequency of the working spectrum of the two devices is 24 MHz (the TV channel is 8 MHz), so the minimum interval between the operating frequencies of the two devices is 3 TV channels.

步骤 403: SC向 DB发送 WS频谱申请消息，其中包含申请 WS资源的 WSD设备参数，及步骤 2分析中确定的 WSD1、 WSD2工作频率的频域间隔要求； Step 403: The SC sends a WS spectrum application message to the DB, where the WSD device parameter for applying for the WS resource and the frequency domain interval requirement for the WSD1 and WSD2 working frequencies determined in the step 2 analysis are included;

步骤 404: DB确定 WSD1、 WSD2的可用频谱；并计算各可用频谱上的最大发射功率限制； Step 404: The DB determines the available spectrum of WSD1 and WSD2; and calculates a maximum transmit power limit on each available spectrum;

可用频谱的确定： 1、 DB基于 WSD1、 WSD2的所在位置，查找 TV系统频语使用情况，存在 TV系统在该区域上未使用的 TVWS资源包括： {信道 25、 26、 28}。 2、考虑共存需求，两设备中心频率最小间隔为 3个 TV信道，因此，两设备仅能分别使用信道 25, 信道 28。 Determination of available spectrum: 1. Based on the location of WSD1 and WSD2, DB searches for TV system frequency usage. TVWS resources that are not used by TV system in this area include: {channels 25, 26, 28}. 2. Considering the coexistence requirement, the minimum frequency of the two device center frequencies is 3 TV channels. Therefore, the two devices can only use channel 25 and channel 28 respectively.

最大允许发射功率的计算：分别针对上述 2个可用信道进行计算，根据 WSD1、 WSD2的设备参数，主系统用户保护准则，主系统用户信息，传播模型，釆用相关技术（具体方法见方法实施例 1的描述）可以计算得出 WSD1、 WSD2在上述 2个可用信道上的最大允许发射功率限制值。计算结果如表 3 所示： Calculation of the maximum allowable transmit power: Calculate for the above two available channels respectively, according to the device parameters of WSD1, WSD2, main system user protection criteria, main system user information, propagation model, and related technologies (see the method example for the specific method) The description of 1) can calculate the maximum allowable transmit power limit value of WSD1, WSD2 on the above 2 available channels. The calculation results are shown in Table 3:

表 3为可用频谱列表 Table 3 is a list of available spectrum

DB将计算得到的 WSD允许最大发射功率与 WSD自身设备支持最大发射功率做比较，取较小的值作为 WSD 的最大允许发射功率，本实施例中，两个固定 WSD的发射功率最大值为 45dBm, 因此 WSD2的发射功率限制为 45dBm。步骤 405: DB将上述可用频谱列表信息（运行参数）发送给 SC;The DB compares the maximum transmit power allowed by the WSD to the maximum transmit power supported by the WSD device, and takes a smaller value as the maximum allowable transmit power of the WSD. In this embodiment, the maximum transmit power of the two fixed WSDs is 45 dBm. Therefore, the transmit power of WSD2 is limited to 45dBm. Step 405: The DB sends the above available spectrum list information (operation parameters) to the SC;

步骤 406: SC进行自共存处理； Step 406: The SC performs self-coexistence processing;

步骤 402在做共存需求分析时，对 WSD2的发射功率做了假定，即 WSD2 发射功率为 40dBm,从上表中可以看出，信道 28,从主系统用户保护的角度，其发射功率可以达到 45dBm,因此需要判断如果 WSD2在信道 28上以 45dBm 进行发射是否能满足 WSD间自共存需求，判断结果为不会对其他 WSD造成干扰； Step 402: In the coexistence demand analysis, the WSD2 transmit power is assumed, that is, the WSD2 transmit power is 40 dBm. As can be seen from the above table, the channel 28 can transmit 45 dBm from the perspective of the main system user protection. Therefore, it is necessary to judge whether the WSD2 can transmit at 45 dBm on the channel 28 to satisfy the self-coexistence requirement between the WSDs, and the judgment result is that it does not cause interference to other WSDs;

步骤 407: 通过步骤 6的判断可知，无需对可用频谱列表作调整，因此， SC将上述可用频谱列表信息（运行参数）转发给 WSD2; Step 407: According to the judgment of step 6, it is known that there is no need to adjust the available spectrum list, so the SC forwards the above available spectrum list information (operation parameters) to WSD2;

步骤 408: WSD1、 WSD2根据实际需求选择可用信道确定发射功率； Step 408: WSD1 and WSD2 select an available channel to determine the transmit power according to actual requirements.

WSD1选择可用信道 25为其工作频谱，发射功率为 40dBm;WSD1 selects available channel 25 as its working spectrum, and the transmit power is 40dBm;

WSD2选择可用信道 28为其工作频谱，发射功率为 40dBm WSD2 selects the available channel 28 as its working spectrum, and the transmit power is 40dBm.

步骤 409、 410: 逐层反馈使用参数给 SC、 DB。 Steps 409, 410: Layer-by-layer feedback uses parameters for SC and DB.

根据彼此的位置关系，传播模型，预期发射参数等信息，且在本实施例中， WSD1具有更高的资源分配优先级，即 WSD1的发射需求是优先满足的，则假定 WSD1发射功率为 40dBm, 计算 WSD2与 WSD1间基于频域隔离的发射参数限制。得出表 4的结果:According to the positional relationship of each other, the propagation model, the expected transmission parameters and the like, and in the embodiment, the WSD1 has a higher resource allocation priority, that is, the transmission requirement of the WSD1 is preferentially satisfied, and the WSD1 transmission power is assumed to be 40 dBm.

可用频谱的确定： 1、 DB基于 WSD1、 WSD2的所在位置，查找 TV系统频语使用情况，存在 TV系统在该区域上未使用的 TVWS资源包括： {信道 25、 26、 28}。 2、考虑共存需求， WSD1具有较高的优先级，因此得到 WSD1 为 40dBm时，各种组合情况下可用频谱列表： Determination of available spectrum: 1. Based on the location of WSD1 and WSD2, DB searches for TV system frequency usage. TVWS resources that are not used by TV system in this area include: {channels 25, 26, 28}. 2. Considering the coexistence requirement, WSD1 has a higher priority, so when WSD1 is 40dBm, the available spectrum list in various combinations:

最大允许发射功率的计算：基于主系统用户保护计算发射功率限制，分别针对上述 3个可用信道进行计算，根据 WSD1、 WSD2的设备参数，主系统用户保护准则，主系统用户信息，传播模型，釆用相关技术（具体方法见方法实施例 1的描述）可以计算得出 WSD1、 WSD2在可用信道上的最大允许发射功率限制值。计算结果如表 6:Calculation of the maximum allowable transmit power: Calculate the transmit power limit based on the primary system user protection, calculate for the above three available channels, according to the WSD1, WSD2 device parameters, the primary system user protection criteria, the primary system user information, the propagation model, 釆The maximum allowable transmit power limit value of WSD1 and WSD2 on the available channels can be calculated by the related art (for details, see the description of Method Embodiment 1).

WSD1、 WSD2发出空闲频谱资源分配请求，共存需求为 "频语数量需求"时，每个 WSD可用频谱及发射功率限制确定的信令流程如图 6所示，下面对其做详细说明： WSD1 and WSD2 send out idle spectrum resource allocation requests. When the coexistence requirement is “frequency number requirement”, the signaling flow determined by each WSD available spectrum and transmit power limit is shown in Figure 6, and the details are described below:

步骤 601 : WSD1、 WSD2向 SC发送 WS频谱资源申请，并提供设备参数，其中包括：天线位置（WSD1 : 东经 55度，北纬 67.5度； WSD2: 东经 54.2度，北纬 67度），定位精度（100m ) , 设备类型（WSD1 : Fixed WSD; WSD2: portable WSD ) ,设备辅射类型（频语模板信息 ) ,技术标识（ LTE ) , 设备统一标识（如 FCC device ID ) , 天线高度（10m ) , 极化方式（水平极化），天线方向角（全向天线），天线俯仰角（25度）； Step 601: WSD1 and WSD2 send a WS spectrum resource request to the SC, and provide device parameters, including: antenna position (WSD1: 55 degrees east longitude, 67.5 degrees north latitude; WSD2: 54.2 degrees east longitude, 67 degrees north latitude), positioning accuracy (100m) ), device type (WSD1: Fixed WSD; WSD2: portable WSD), device auxiliary type (frequency template information), technical identification (LTE), device uniform identification (such as FCC device ID), antenna height (10m), pole Mode (horizontal polarization), antenna direction angle (omnidirectional antenna), antenna pitch angle (25 degrees);

The DB searches for the frequency usage of the TV system based on the location of WSD1 and WSD2. The TVWS resources that are not used by the TV system in the area include: {channels 25, 26, 28, 30}. 2. Considering the coexistence requirement, WSD1 requires two consecutive TVWS channels, and WSD2 requires one TVWS channel; therefore, WSD1 available spectrum is {channel 25, 26}, WSD2 The available frequency is channel 28 or 30, and the frequency domain isolation distance between the two is 24 MHz, so the available spectrum of WSD2 is channel 30:

场景 5:Scene 5:

WSD1 发出空闲频谱资源分配请求，共存需求为 "禁用频率限制" 时，该 WSD可用频谱及发射功率限制确定的信令流程如图 7所示，下面对其做详细说明：WSD1 sends a free spectrum resource allocation request. When the coexistence requirement is "disabled frequency limit", the signaling process determined by the WSD available spectrum and transmit power limit is shown in Figure 7. Detailed description:

步骤 701 : WSD1向 SC发送 WS频谱资源申请，并提供设备参数，其中包括：天线位置（东经 54.2度，北纬 67度），定位精度（100m ) , 设备类型（ Fixed WSD ) ，设备辅射类型（频语模板信息），技术标识（LTE ) ，设备统一标识（如 FCC device ID ) , 天线高度（ 10m ) , 极化方式（水平极化 ) , 天线方向角（全向天线），天线俯仰角（25度）； Step 701: WSD1 sends a WS spectrum resource request to the SC, and provides device parameters, including: antenna position (54.2 degrees east longitude, 67 degrees north latitude), positioning accuracy (100m), device type (Fixed WSD), device auxiliary type ( Frequency template information), technical identification (LTE), device uniform identification (such as FCC device ID), antenna height (10m), polarization mode (horizontal polarization), antenna direction angle (omnidirectional antenna), antenna pitch angle ( 25 degree) ;

步骤 702: SC收到 WSD1的频谱资源申请后，向 DB发送 WS频谱申请消息，其中包含申请 WS资源的 WSD设备参数。 Step 702: After receiving the application for the spectrum resource of the WSD1, the SC sends a WS spectrum application message to the DB, where the WSD device parameter for requesting the WS resource is included.

步骤 703: DB确定 WSD1所在位置的主系统用户设备未使用频谱； DB基于 WSD1的位置，查找 TV系统频语使用情况，存在 TV系统在该区域上未使用的 TVWS资源包括： {信道 25、 30、 34、 40、 45、 46、 50}。 Step 703: The DB determines that the primary system user equipment at the location of the WSD1 does not use the spectrum; the DB searches for the frequency usage of the TV system based on the location of the WSD1, and the TVWS resources that are not used by the TV system in the area include: {channel 25, 30 , 34, 40, 45, 46, 50}.

DB向 SC反馈主系统未使用频谱： {信道 25、 30、 34、 40、 45、 46、 50}。步骤 704: SC针对 DB反馈的主系统用户设备未使用频谱查找该 WSD1 所在位置区域内及相邻区域内除所述 WSD外的其他 WSD的 TVWS频语使用情况，分析共存需求； The DB feeds back to the SC that the primary system is not using the spectrum: {channels 25, 30, 34, 40, 45, 46, 50}. Step 704: The primary system user equipment that the SC feeds back to the DB does not use the spectrum to find the TVWS frequency usage of the WSDs in the location area of the WSD1 and in the adjacent area except the WSD, and analyzes the coexistence requirement;

WSD1附近存在 3个 WSD工作在 TVWS资源上，分别为： WSD2、 WSD3、 WSD4。具体信息如下表 9所示。 There are three WSDs working in TVWS resources near WSD1, namely: WSD2, WSD3, WSD4. The specific information is shown in Table 9 below.

表 9为 WSD1附近的 3个 WSD的资源使用情况表 Table 9 shows the resource usage of three WSDs near WSD1.

SC利用传播模型，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，得出在满足彼此互不干扰的条件下： The SC uses the propagation model to calculate the interference relationship between the above three WSDs and WSD1 (here, the transmission power is assumed according to the type of WSD1, and the WSD1 transmission power is assumed to be 40 dBm in this embodiment), and the frequency domain isolation distance between each other is determined. , in the condition that they do not interfere with each other:

WSD2与 WSD1间频域隔离距离为两个 TV信道，即 TV信道 33、 34、 35对于 WSDl为禁用频谱；The frequency separation between WSD2 and WSD1 is two TV channels, namely TV channels 33, 34, 35 for WSDl is disabled spectrum;

WSD3与 WSD1间的频域隔离距离为 1个 TV信道，即不同频即可，信道 40对于 WSD1为禁用频谱； The frequency domain isolation distance between WSD3 and WSD1 is 1 TV channel, that is, different frequency, and channel 40 is disabled spectrum for WSD1;

因此，共存需求为： WSD1 禁用信道： 33、 34、 35、 40、 45。在主系统用户设备未使用频谱中，信道 34、 40、 45为禁用频谱。 Therefore, the coexistence requirements are: WSD1 disable channels: 33, 34, 35, 40, 45. In the unused spectrum of the primary system user equipment, channels 34, 40, 45 are disabled spectrum.

步骤 705: SC向 DB发送共存需求消息，即信道 34、 40、 45为禁用频谱。步骤 706: DB确定 WSD1的可用频谱；并计算每个可用频谱上的最大发射功率限制； Step 705: The SC sends a coexistence demand message to the DB, that is, the channels 34, 40, and 45 are disabled spectrum. Step 706: The DB determines the available spectrum of WSD1; and calculates a maximum transmit power limit on each available spectrum;

可用频谱的确定： TV系统在该区域上未使用的 TVWS资源包括： {信道 Determination of available spectrum: TVWS resources that are not used by the TV system in this area include: {channel

25、 30、 34、 40、 45、 46、 50}。 SC反馈的禁用 TVWS资源为 {信道 34、 40、 45} , 因此， WSD1的可用频谱为： {信道 25、 30、 46、 50}。25, 30, 34, 40, 45, 46, 50}. Disabled SC feedback The TVWS resource is {channel 34, 40, 45}. Therefore, the available spectrum of WSD1 is: {channel 25, 30, 46, 50}.

最大允许发射功率的计算：分别针对上述 4个可用信道进行计算，根据 WSD1 的设备参数，主系统用户保护准则，主系统用户信息，传播模型，釆用相关技术（具体方法见方法实施例 1的描述）可以计算得出 WSD1在上述 4个可用信道上的最大允许发射功率限制值。计算结果如表 10所示： Calculation of the maximum allowable transmit power: Calculate for the above four available channels respectively, according to the WSD1 device parameters, the main system user protection criteria, the main system user information, the propagation model, and the related technologies (for the specific method, see Method Embodiment 1). Description) The maximum allowable transmit power limit value of WSD1 on the above 4 available channels can be calculated. The calculation results are shown in Table 10:

表 10为可用频谱列表 Table 10 shows the list of available spectrums.

步骤 707: DB将上述可用频谱列表信息（运行参数）发送给 SC; Step 707: The DB sends the foregoing available spectrum list information (operation parameters) to the SC;

步骤 708: SC进行自共存处理； Step 708: The SC performs self-coexistence processing;

步骤 702在做共存需求分析时，对 WSD1的发射功率做了假定，即 WSD1 发射功率为 40dBm,从上表中可以看出，信道 30,从主系统用户保护的角度，其发射功率可以达到 50dBm,因此需要判断如果 WSDl在信道 30上以 50dBm 进行发射是否能满足 WSD间自共存需求，判断结果为不会对其他 WSD造成干扰；In step 702, when the coexistence demand analysis is performed, the transmit power of WSD1 is assumed, that is, the transmit power of WSD1 is 40 dBm. As can be seen from the above table, the channel 30 can transmit 50 dBm from the perspective of user protection of the main system. Therefore, it is necessary to judge whether the WSD1 can transmit at 50 dBm on the channel 30 to satisfy the self-coexistence requirement between WSDs, and the judgment result is that it will not cause other WSDs. Interference

步骤 709: 通过步骤 706的判断可知，无需对可用频谱列表作调整，因此， SC将上述可用频谱列表信息（运行参数）转发给 WSD1 ; Step 709: According to the judgment of step 706, it is not necessary to adjust the available spectrum list, so the SC forwards the above available spectrum list information (operation parameters) to WSD1;

步骤 710: WSD1根据实际需求选择可用信道确定发射功率； Step 710: WSD1 selects an available channel according to actual requirements to determine a transmit power.

选择可用信道 25为其工作频谱，发射功率为 40dBm; Select available channel 25 as its working spectrum, and transmit power is 40dBm;

步骤 711、 712: 逐层反馈使用参数给 SC、 DB。 Steps 711, 712: Layer-by-layer feedback uses parameters for SC and DB.
