Abstract

本公开涉及动态资源共享。根据本公开实施例，提供一种由网络节点执行的方法，包括：确定所述网络节点的资源余量；和将所述资源余量的信息上载到区块链。本公开实施例提供了更灵活更安全的动态资源共享。

Description

动态资源共享 技术领域
本公开总体上涉及通信技术，更具体而言，本公开涉及用于动态资源共享的方法、设备和系统。
背景技术
随着通信技术的发展，网络节点部署更加密集，同时手机、物联网设备、可穿戴设备等各类形态的终端数量急剧增长，对频谱资源的需求越来越大。由于业务的异构和动态性，传统的静态频谱管理方案频谱利用率低下，浪费了宝贵的频谱资源。因此，认知无线电技术被提出，由次用户通过例如频谱感知发现主用户的空闲频谱并利用该空闲频谱来进行传输，以提高频谱利用率。但是目前中心化的频谱共享方案中，频谱管理装置需要大量的计算资源，频谱管理设备间的同步频率低，频谱管理的实时性不高。
近来，已提出将区块链技术引入频谱管理中，以设计更安全、灵活的频谱共享机制，使得能够在提升频谱利用率的同时，提高频谱交易的安全性。可以将公共区块链的技术应用于频谱感知、频谱拍卖和频谱交易中。但可能存在以下问题：使用区块链分配的频谱资源在一定周期内仍完全属于某个基站使用，而该基站在该周期内对频谱的使用仍可能不充分。

通过参照附图阅读以下详细描述，本公开的特征和方面将得到清楚的理解。
具体实施方式
在下文中将参照附图来详细描述本公开的各种示例性实施例。为了清楚和简明起见，在本说明书中并未描述实施例的所有实现方式。然而应注意，在实现本公开的实施例时可以根据特定需求做出很多特定于实现方式的设置，以便实现开发人员的具体目标。此外，还应该了解，虽然开发工作有可能是较复杂和费事的，但对得益于本公开内容的本领域技术人员来说，这种开发公开仅仅是例行的任务。
此外，还应注意，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与本公开的技术方案密切相关的处理步骤和/或设备结构。以下对于示例性实施例的 描述仅仅是说明性的，不意在作为对本公开及其应用的任何限制。
本公开考虑，在网络中的网络节点(诸如基站)之间建立区块链，该区块链用于记录网络内的各个网络节点的资源余量的动态变化和频谱交易记录。根据资源使用需求不同，一网络节点既可以释放资源余量(例如功率余量或带宽余量)以供网络内的其它网络节点(例如附近的网络节点)使用，也可以从其它网络节点获取由其它网络节点释放的资源余量。网络节点可以将资源余量的信息上载到区块链，也可以查询区块链上的当前可用资源余量。在两个网络节点完成资源余量的交易的情况下，该交易的记录也可以上载到区块链，以更新区块链上的资源余量的信息。
通过将区块链与网络节点的资源余量的交易相结合，可以以安全灵活的方式实现网络节点之间的资源余量的动态共享，改善各个网络节点的通信服务质量并且提高网络的资源利用率。
本公开考虑，由分布式的网络节点来承担区块链的维护、资源交易的验证工作等，从而将原本集中在资源管理设备处的至少部分资源管理功能转移到网络节点，促成了更有效、更灵活、更安全的资源共享。
本公开还考虑，各个网络节点可以通过采用可重构智能表面(Reconfigurable Intelligent Surface，RIS)或调整RIS的配置来获取资源余量。这不仅可以提高网络节点处的资源利用率和通信服务质量，还可以提高网络整体的资源利用率和通信服务质量。
本公开还考虑，各个网络节点可以在发生资源使用调整(例如调整RIS配置，调整发射参数等)时将调整后的资源使用的信息实时上报给资源管理设备(例如，频谱管理设备)，以用于由资源管理设备更新网络的覆盖重叠图。这使得资源管理设备处的覆盖重叠图能够实时跟踪网络内的网络节点间的通信干扰的变化。
在资源使用调整涉及RIS配置调整的情况下，资源使用的信息可以包括RIS配置相关的信息，资源管理设备根据RIS配置相关的信息可以生成更精确的覆盖重叠图。
本公开还考虑，在两个网络节点进行资源余量的交易时，可以利用最新的覆盖重叠图来对该交易进行验证，以避免该交易导致对网络内的其它受保护的网络节点(例如主系统的网络节点)的不期望的干扰。
图1是示出根据本公开实施例的网络100的示例性系统结构图。
网络100可以包括主系统和次系统。以公民宽带无线电服务(Citizens Broadband  Radio Services，CBRS)系统为例，主系统可以包括现有用户例如雷达(Incumbents)或优先接入许可(Priority Access License，PAL)网络节点，例如，雷达或PAL公民宽带无线电服务设备(Citizens Broadband Radio Service Device，CBSD)102。次系统可以包括一般授权接入(General Authorized Access，GAA)网络节点，例如，GAA CBSD 104、106和108。
每个CBSD为各自的用户，即用户设备UE，提供服务。次系统中的GAA用户不能影响主系统中的雷达或PAL用户。
次系统可以包括一定区域内的若干GAA网络节点。次系统中的各个网络节点之间可以实现动态资源共享。可以将区块链技术应用于次系统中的动态资源共享，例如在这些GAA网络节点之间建立区块链。各个网络节点106-108可以将各自的资源余量的信息或资源使用信息或这些信息的变化实时上载到区块链，从而允许各个网络节点对网络内的可用资源余量的信息进行查询以及进行资源交易，从而实现更高效、更安全和更灵活的资源共享。
如图1所示，CBSD 104和106各自配备了可重构智能表面(Reconfigurable Intelligent Surface，RIS)以及控制RIS的RIS控制器RIS-C。在一些实施例中，RIS控制器可以与CBSD有线连接。RIS可以部署在CBSD侧、中继侧或用户侧。
CBSD能够经由RIS控制器来实时控制RIS的反射系数(例如图1中的)以按照需求动态地构造反射路径。
图2是示出根据本公开实施例的RIS控制器控制RIS反射系数的示意图。如图2所示，RIS控制器可以通过控制RIS的各反射单元的相位偏移来调整入射波的出射方向(例如出射角度θ)。
如图2所示，RIS可以包括多个RIS单元，每个单元可以独立控制，例如每个单元的可以独立设置。在一些实施例中，可以针对各个单元的设置相同的值来对接收到的入射信号实现相同的相位偏移。在另一些实施例中，可以针对每个单元的设置不同的值来针对不同入射信号实现不同的相位偏移。
图2仅例示了反射系数为相位偏移的示例。除了相位偏移，可以经由RIS控制器控制的RIS的反射系数还可以包括幅度偏移、频率、极化等。
按照在区块链网络中的功能，CBSD可以分为两类：一类是轻量CBSD，其可以只记录自己的资源使用和交易记录；另一类是标准CBSD，其可以存储区块链上的全部当前可用资源信息及新近的资源使用信息，可以验证最新生成的待确认的区块的信息， 可以服务本地的轻量CBSD，提供其所需信息等。已经完成验证并且成为历史信息的区块链可以存储在资源管理设备上。资源管理设备例如是共存管理器(Coexistence Manager，CxM)、频谱接入系统(Spectrum Access System，SAS)或CSAS(SAS+CxM)等。资源管理设备可以是频谱管理装置或设备。
图3是示出根据本公开实施例的动态资源管理方法的示例性信令交互过程300的流程图。
图3示出CBSD 1、CBSD 2、标准CBSD和CxM。假设CBSD 1为轻量CBSD并且配备了RIS和RIS控制器，CBSD 2为轻量CBSD，标准CBSD为与区块链相关联的多个标准CBSD中的一个并且保存与区块链相关联的本地账本，CxM是资源管理设备。标准CBSD可以产生区块。
如图3所示，过程300包括步骤1，在该步骤，CBSD 1、CBSD 2和标准CBSD可以向CxM发送注册请求，以在CBSD之间建立用于动态资源共享的区块链。
在一些实施例中，可以先前已经建立了区块链，当一个新的CBSD要加入该区块链时，可以向CxM发送注册请求。
在一些实施例中，注册请求可以指示进行注册的CBSD是否支持区块链功能，该CBSD的类型是轻量节点还是标准节点等。
CBSD注册的信息可以包括以下信息中的一者或多者：地理位置，最大有效全向辐射功率(Effective Isotropic Radiated Power，EIRP)或请求EIRP，天线高度，CBSD类别(指示室内低功率设备的类别A或指示室外高功率设备的类别B)，授权状态(PAL或GAA)，ID号，用户联系信息，空口技术，序列号，感测能力(如果支持的话)，其他部署配置(例如天线增益，波束宽度，方位角，用于类别B的下倾角)、分组信息、节点类型(轻量或标准)，是否支持区块链功能，是否配置RIS，以及RIS配置参数(如果配置了RIS的话)。
过程300可以包括步骤2a，在该步骤，CBSD 1调整所配备的RIS的配置，例如调整RIS的反射系数。
CBSD 1可以根据主系统信息、用户移动性、用户的QoS需求等来调整RIS的配置，使得调整后的发射信号能够满足用户服务需求，也能够满足对受保护节点(例如主系统的CBSD和/或其它受保护CBSD)的干扰保护要求，同时相对于调整之前使用了更少的资源(例如使用了更低的功率和/或使用了更小的带宽)。主系统信息可以包括主系统能够容忍的最大干扰总量。
CBSD可以向其关联的RIS控制器RIS-C发送控制信号，来控制RIS调整配置参数，例如反射系数。
如图3所示，过程300还可以包括步骤2b，在该步骤，CBSD 1确定通过调整RIS的配置参数获得/增加的资源余量。
CBSD 1可以确定通过调整RIS配置所获得/增加的增益。通过所获得/增加的增益可以确定CBSD 1的资源余量，例如，可以降低的功率余量或可以释放的信道资源。
图4是示出根据本公开实施例的通过配置RIS反射系数释放资源余量的示意图。为了说明简单，图4将使用RIS的情况和没有使用RIS的情况来作为对比。假设主系统保护区内只有CBSD1和CBSD2两个次系统。
图4的左边示出当CBSD 1没有使用RIS时的情况，其中，CBSD 1向UE 1进行的发射对主系统(由PZ/PPA表示)造成了干扰。这里假设主系统能够容忍的最大干扰总量是-80dBm，CBSD 1对主系统造成了-77dBm的干扰。此时，CBSD 2由于对主系统的干扰保护，只能以较小的发射功率提供较小的覆盖范围，UE2落在了其覆盖范围以外。
图4的右边示出当CBSD 1采用RIS并利用RIS的配置将发射波束准确导向UE 1时，相对于没有使用RIS的情况，其发射功率降低，提供了干扰余量。假设CBSD 1对主系统的干扰减小到-85dBmdB，则只要CBSD1和CBSD 2对主系统的聚合干扰控制在-80dBm以内，就不会对主系统造成干扰。在这种情况下，CBSD 2可以提高自己的发射功率来提供更大的覆盖范围从而为UE 2提供服务。
在进行RIS的反射系数的配置时，根据用户(例如UE 1)的位置和主系统的位置(例如图4中由PZ/PPA指示的区域)，使得经RIS反射后的反射信号主波束指向用户UE 1的方向，同时避开主系统。
作为示例，假设网络中存在k个RIS，第k个RIS的反射系数Ψk可以建模为对角矩阵：
其中，M表示该RIS的反射单元的数目，βk,1到βk,M表示M个反射单元的相位偏移系数，到和分别表示M个反射单元的幅度偏移系数。
在确定好反射系数之后，可以根据端用户设备，例如图4中的UE1，的测量信息确定RIS增益为G(dB)。例如，可以根据UE 1所测量的参考信号接收功率 (Reference Signal Received Power，RSRP)计算信噪比差异，从而确定通过RIS调整获得的增益。
根据香农公式，使用RIS前的吞吐量为：
其中，SINR是指接收端测得的信噪比。
假设用户获得的服务质量不变，CBSD可以按照以下两种方式来释放资源余量：
一种是降低功率，降低的功率可以表示为：ΔP(dB)＝G(dB)
另一种是减小带宽，使用RIS后的带宽可以表示为：
减小的带宽可以表示为：ΔW＝W-WRIS
如图3所示，过程300还可以包括步骤2c，在该步骤，CBSD 1将所确定的资源余量的信息上载到区块链。
例如，CBSD 1可以将RIS调整之后的资源余量的信息记录到CBSD 1的与区块链相关联的本地账本中，并向网络内的标准CBSD广播。如上所述，CBSD 1是轻量节点，其可以仅记录本身的资源余量信息或与自己相关联的交易的信息。网络中的各个标准节点在接收到CBSD 1发送的资源余量信息时，验证CBSD 1的节点信息并将CBSD 1的资源余量信息记录到各自的本地账本上。资源余量的信息可以包括功率余量和带宽余量中的至少一者。
在一些实施例中，CBSD 1可以向多个标准CBSD中的一个上报资源余量的信息，接收到该信息的标准CBSD生成包含该信息的新区块，将其记录到本地区块链账本中，并将新区块广播给网络内的其它标准CBSD以供其它标准CBSD存储在各自的本地账本中。这样，完成资源余量信息到区块链的上载。
图5是示出根据本公开实施例的区块的区块结构的示意图。
如图5所示，区块包括区块头和区块主体。
区块头可以包括前一区块的哈希值、当前区块的哈希值、默克尔树根哈希等。
区块主体可以包括但不限于：CBSD新释放的干扰余量(即资源余量)，包括新的功率余量和/或带宽余量；CBSD通过进行资源交易，使用其他CBSD释放的资源的信息；每次交易完后更新的最新的干扰余量信息。
图5中所示出的是一个示例性区块。本领域技术人员可以根据需要在区块中包含更多或其它信息。
如图3所示，过程300还可以包括步骤2d，在该步骤，CBSD 1将RIS调整之后的资源使用信息上报给CxM。
资源使用信息可以包括RIS配置有关的信息。RIS配置有关的信息可以包括经RIS反射后的反射信号的信号方向和/或功率。资源使用信息还可以包括接收信号强度指示符(Received Signal Strength Indicator，RSSI)和/或接收信号方向。
在一些实施例中，CBSD 1可以经由HeartbeatRequest向CxM上报CoexMeasInfo和cellInfo信息。
CoexMeasInfo可以包括channelReport和signalReport。channelReport和signalReport除报告RSSI外，还可以报告接收信号的方位。
cellInfo的信息中，可以包括经RIS反射后的反射信号的信号方向。cellInfo的信息中也可以包括其他信息，例如E-UTRA绝对无线频率信道号(E-UTRA Absolute Radio Frequency Channel Number，EARFCN)，RAT，PCI带宽(PCIbandwidth)等。
如图3所示，过程300还可以包括步骤3，在该步骤，CxM基于从CBSD 1接收到的资源使用信息来更新覆盖重叠图。
CBRS联盟(CBRS Alliance，CBRSA)共存组(Coexistence Group，CxG)可以包括例如按照不同运营商划分的多个不同的干扰协调组(Interference Coordination Group，ICG)。CxG是这样一组CBSD，该组CBSD遵循用于在该组内协调他们的干扰的公共干扰管理策略。一个ICG组可以包括多个公共信道组(Common Channel Group，CCG)，其中属于一个CCG的所有CBSD要求同样的信道分派。CxM可以负责管理CxG内的CBSD之间的共存。
CSAS可以识别ICG内的一组或多组CBSD。对于所识别的ICG内的每组CBSD，CSAS可以向CxM提供该组CBSD的列表，有关这些CBSD的信息以及为该组CBSD分派的频谱池。所述信息可以包括CBSD注册信息，例如每个CBSD的位置，最大EIRP或请求EIRP(如果可用的话)，天线布置的高于平均地面的高度(height above  average terrain，HAAT)、天线特征和分组信息等。
针对每组识别的CBSD，CxM可以使用CSAS提供的信息来创建覆盖重叠图，其表示CBSD之间的干扰关系。
相关技术中，创建覆盖重叠图的具体过程如下：
1)CxM创建图中的顶点：
1-1)CxM为属于同一个CCG的所有CBSD创建一个顶点。
1-2)如果一个CBSD不属于任何CCG，CxM为该CBSD创建一个顶点。
2)CxM创建图中的边。可以按照如下规则在两个顶点之间创建边：
2-1)根据CBSD之间的覆盖重叠建立边。
2-2)在属于不同ICG的共址CBSD之间有边。共址CBSD可以指共享相同物理地点并且可能共享相同天线即共享基础设施或物理上临近的CBSD。
2-3)属于同一个ICG的所有CBSD之间都没有边。
2-4)可以根据对传播环境、RF测量、网络性能、干扰状态等的建模来创建边。
在CxM创建覆盖重叠图之后，可以找到该图的不同连接组件，每个连接组件变成“信道分配连接集”。此时，CxM可以分别考虑每个“信道分配连接集”并单独为每个信道分派连接集执行主信道分派：
1)CxM在整个图中以最小着色数目对信道分配连接集的每个顶点进行着色，使得具有边的任意两个顶点具有不同着色。
2)可用于信道分派连接集的频谱可以被划分成正交的和相等的主信道，并且每个顶点被分配这些信道中与图中的该顶点的着色对应的主信道。
本申请中，针对不属于同一个ICG或CCG的CBSD，修改覆盖重叠图的创建过程。
首先结合图6A描述假设两个CBSD，例如CBSD 1和CBSD 2，不属于同一个ICG或CCG且均采用RIS的情况。
资源管理设备(例如CxM)可以从CBSD 1和CBSD 2接收各自的资源使用信息。CBSD的资源使用信息可以包括RIS配置相关的信息，例如可以包括经RIS反射后的反射信号的方向和功率。资源管理设备可以知道两个CBSD的位置。
CxM可以如下来创建或更新覆盖重叠图：
1)判断CBSD 1的经RIS反射后的反射信号的方向(以下，称为第一信号方向) 与CBSD 2的经RIS反射后的反射信号的方向(以下，称为第二信号方向)是否交叉：
1-1)如果第一信号方向与第二信号方向不交叉，CBSD 1和CBSD 2之间没有边；
1-2)如果第一信号方向与第二信号方向交叉，判断交叉点处的干扰信号功率是否超过干扰阈值：
1-2-1)如果交叉点处的干扰信号功率超过干扰阈值，则在CBSD 1和CBSD 2之间创建边。这意味着在后续着色过程中，CBSD 1和CBSD 2需要使用不同的着色。
1-2-2)如果交叉点处的干扰信号功率没有超过干扰阈值，则在CBSD 1和CBSD 2之间没有边。
交叉点处的干扰信号功率是指干扰方在交叉点处产生的信号功率。
若交叉点位置有用户设备，也可以根据用户设备测量上报的RSRP来判断交叉点处的干扰信号功率是否超过干扰阈值。
图6A左边示出在CBSD 1和CBSD 2没有采用RIS的情况下，两者的发射波束相互干扰，在覆盖重叠图中，表示CBSD 1和CBSD 2的两个顶点之间存在边。即两个CBSD存在覆盖重叠，需要使用不同的着色，不能使用相同的频谱资源。
图6A右边示出CBSD 1和CBSD 2两者的发射波束相互不干扰，在覆盖重叠图中，表示CBSD 1和CBSD 2的两个顶点之间不存在边。即两个CBSD不存在覆盖重叠，可以使用相同的着色，可以使用相同的频谱资源。请注意，在图6A中，用灰色三角和黑色边框的三角形来表示不同着色。
可以结合图6B描述CBSD 1没有采用RIS而CBSD 2采用RIS并且CBSD 1和CBSD 2不属于同一个ICG或CCG的情况。
资源管理设备(例如CxM)可以从CBSD 1和CBSD 2接收各自的资源使用信息。CBSD 2的资源使用信息可以包括RIS配置相关的信息，例如可以包括经RIS反射后的反射信号的方向和功率。CBSD 1的资源使用信息可以包括CBSD 1的发射信号的方向和功率。资源管理设备知道CBSD 1和CBSD 2的位置。
CxM可以如下来创建或更新覆盖重叠图：
1)判断CBSD 1的发射信号的方向(第一信号方向)与CBSD 2的经RIS反射后的发射信号的方向(如上，还称为第二信号方向)是否交叉：
1-1)如果第一信号方向与第二信号方向不交叉，CBSD 1和CBSD 2之间没有边；
1-2)如果第一信号方向与第二信号方向交叉，判断交叉点处的干扰信号功率是否超过干扰阈值：
1-2-1)如果交叉点处的干扰信号功率超过干扰阈值，则在CBSD 1和CBSD 2之间创建边。这意味着在后续着色过程中，CBSD 1和CBSD 2需要使用不同的着色。
1-2-2)如果交叉点处的干扰信号功率没有超过干扰阈值，则在CBSD 1和CBSD 2之间没有边。
图6B左边示出在CBSD 2没有采用RIS的情况下，CBSD 1和CBSD 2的发射波束相互干扰，在覆盖重叠图中，表示CBSD 1和CBSD 2的两个顶点之间存在边。即两个CBSD存在覆盖重叠，需要使用不同的着色，不能使用相同的频谱资源。
图6B右边示出CBSD 1和CBSD 2两者的发射波束相互不干扰，在覆盖重叠图中，表示CBSD 1和CBSD 2的两个顶点之间不存在边。即两个CBSD不存在覆盖重叠，可以使用相同的着色，可以使用相同的频谱资源。
回到图3，过程300还可以包括步骤4a，在该步骤，CBSD 2可以向标准CBSD发送资源查询请求。
CBSD 2可以向与区块链相关联的多个标准CBSD中的任一个(例如附近的一个标准CBSD)发送资源查询请求，以获取与区块链上的当前可用资源有关的信息。
如果CBSD 2是轻量CBSD，其可以周期性的或按需向标准CBSD发送资源查询请求，以查询最新的干扰余量的信息。
如果CBSD 2是标准CBSD，其可以从本地存储的区块链账本查询最新的干扰余量的信息。
如图3所示，过程300还可以包括步骤4b，在该步骤，标准CBSD响应于接收到的资源查询请求，从区块链获取可用资源的信息。
例如，响应于该请求，标准CBSD可以从本地存储的区块链账本查询最新的资源余量的信息，例如当前可用的功率余量和/或带宽余量。
如图3所示，过程300还可以包括步骤4c，在该步骤，标准CBSD向CBSD 2发送资源查询响应。
标准CBSD将当前可用的资源余量的信息包括在资源查询响应中，并将资源查询响应发送给CBSD 2。
如图3所示，过程300还可以包括步骤4d，在该步骤，CBSD 2向标准CBSD发送资源竞拍请求。资源竞拍请求可以包括指示所竞拍的资源的信息。
CBSD 2在接收到资源查询响应时，可以基于网络的当前可用资源余量确定要请求增加额外的资源，例如额外的发射功率和/或额外的带宽，以满足自己的通信需求。CBSD 2可以向标准CBSD发送资源竞拍请求，可以随资源竞拍请求发送一定数量的保证金。在一些实施例中，资源竞拍请求可以是调整发射参数请求，发射参数例如是与信道范围和/或发射功率有关的参数。
在CBSD 2本身是标准网络节点的情况下，CBSD 2可以向另一个标准CBSD发送资源竞拍请求。
如图3所示，过程300还可以包括步骤5a，在该步骤，标准CBSD在接收到资源竞拍请求时，从CxM获取覆盖重叠图。
在一些实施例中，标准CBSD可以向CxM发送针对覆盖重叠图的请求。CxM响应于该请求，向标准CBSD发送最新的覆盖重叠图。
接下来，在步骤5b，标准CBSD可以对该资源竞拍请求所涉及的交易进行验证。
验证可以包括竞价验证，即，判断接收到的资源竞拍请求是否是网络内的所有CBSD收到的所有对相同资源的竞拍请求中竞价最高的竞拍请求。这可以由网络内的所有标准CBSD协作进行该确定。例如，各个标准CBSD可以将自己收到的最高竞价广播给其它标准CBSD。各个标准CBSD可以根据接收到的最高竞价来确定自己收到的资源竞拍请求的竞价是不是最高竞价。
如果一个标准CBSD收到的资源竞拍请求的竞价不是最高竞价，则标准CBSD可以拒绝该资源竞拍请求，例如向发送该资源竞拍请求的CBSD发送拒绝响应。如果一个标准CBSD收到的资源竞拍请求的竞价是最高竞价，则可以对该资源竞拍请求进行更多其它验证。
验证可以包括对资源竞拍请求所涉及的交易进行干扰验证。标准CBSD可以验证该交易是否满足对其它受保护的CBSD(例如主系统的CBSD，和/或附近的其它CBSD)的干扰保护要求。
在一些实施例中，标准CBSD可以根据获取的最新的覆盖重叠图和主系统信息，判断交易后的资源使用是否对其它受保护节点的干扰低于阈值。
例如，如果主系统的最大容忍干扰总量为-80dBm，则可以判断交易之后次系统对主系统所产生的干扰总量是否满足该要求。
例如，还可以判断交易后的资源使用是否在覆盖重叠图中产生不期望的边。在一些实施例中，标准CBSD可以假定该交易产生并基于接收的覆盖重叠图而计算更新的 覆盖重叠图，将更新的覆盖重叠图与接收的覆盖重叠图进行比较，来确定是否产生了不期望的边。
从网络的角度来看，如果竞价最高的资源竞拍请求没有通过干扰验证，则竞价次高的资源竞拍请求将被进行干扰验证，依次类推，直到产生通过干扰验证的资源竞拍请求。
如图3所示，过程300还可以包括步骤5c，在该步骤，标准CBSD向CBSD 2发送资源竞拍响应。资源竞拍响应可以包括对资源竞拍请求所竞拍的资源的使用授权。
如图3所示，过程300还可以包括步骤5d，在该步骤，标准CBSD可以向CBSD1支付报酬。
本领域技术人员可以理解，CBSD 2可以通过一个资源竞拍请求来获得从多个CBSD释放的资源余量，在该情况下，标准CBSD可以向资源竞拍请求的交易所涉及的多个CBSD分别支付各自的报酬。
如图3所示，过程300还可以包括步骤5c，在该步骤，标准CBSD将资源竞拍请求所涉及的交易的记录上载到区块链。
接收该资源竞拍请求并对其进行响应的标准CBSD可以将该交易的记录添加到区块链的本地账本中，形成新的区块，并将该新的区块(其包含与新的交易的记录有关的信息)广播给其它标准CBSD。
如图3所示，过程300还可以包括步骤6a，在该步骤，CBSD 2通过调整发射参数来使用所获得的资源余量。例如，CBSD 2可以提高发射功率和/或增大使用的带宽。
在CBSD 2是配备了RIS和RIS控制器的CBSD的情况下，步骤6a的调整发射参数可以包括调整RIS的反射系数。
如图3所示，过程300还可以包括步骤6b，在该步骤，CBSD 2将调整发射参数之后的资源使用信息上报给CxM，以用于由CxM更新覆盖重叠图。
在CBSD 2是配备了RIS和RIS控制器的CBSD的情况下，步骤6b上报的资源使用信息可以包括RIS配置有关的信息。
上报的资源使用信息例如可以包括CBSD ID、信道、EIRP功率等。上报资源使用信息与步骤2d类似，在此不再赘述。
如图3所示，过程300还可以包括步骤7，在该步骤，CxM基于从CBSD 2接收的资源使用信息更新覆盖重叠图。
本领域技术人员可以理解，CxM仅仅是资源管理设备的示例，可以理解，资源管 理设备还可以是SAS或CSAS等。换言之，以上结合CxM描述的功能或操作也可以由SAS或CSAS等执行。
本领域技术人员可以理解，图3中所示出的步骤仅仅是示例性的，根据本公开教导能够实现包含更多或更少步骤或包含其他步骤的方法，并且步骤之间的先后顺序可以调整。
