Description

无线通信系统中的电子设备、用户设备和无线通信方法
本申请要求于2016年1月13日提交中国专利局、申请号为201610021159.0、发明名称为“无线通信系统中的电子设备、用户设备和无线通信方法”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
本公开涉及无线通信的技术领域，具体地涉及无线通信系统中的电子设备和用于在无线通信系统中进行无线通信的方法。
背景技术
这个部分提供了与本公开有关的背景信息，这不一定是现有技术。
随着无线通信技术的发展，频谱资源越来越紧张，而现有的研究表明，已分配的授权频谱的资源利用率普遍不高，因此如何提高频谱利用率是一个急需解决的问题。认知无线电是软件无线电技术的一个智能化演进，在认知无线电中，以“机会方式”接入频谱的次用户(Secondary User，SU)能够通过对频谱的感知和分析，智能地使用空闲频谱并避免对拥有授权频段的主用户(Primary User，PU)形成干扰，而主用户以最高的优先级使用被授权的频段。当主用户要使用授权频段时，次用户需要及时停止使用频谱，将信道让给主用户。认知无线电技术的引入,可以很大程度上改善频谱资源紧张的问题。
但是，在认知无线电系统中，由于在相同频段下发射不同的调制信号，次用户发出的信号对于同频段的主用户有可能产生干扰，因此次用户分配频谱时需要考虑对主用户的影响，即不能使用主用户所使用的频谱，这样次用户能够使用的频谱资源非常有限。另一方面，相邻系统的次用户可能会共用频谱，然而共用频谱有可能产生干扰。
NOMA(Non-orthogonal multiple access，非正交多址接入)也是一种提高频谱利用率的关键技术。NOMA的基本思想是在发送端采用非正交传输，主动引入干扰信息，在接收端通过串行干扰消除实现正确解调。虽然这种设计会增加接收机的复杂度，但是可以很好地提高频谱利用率。
本发明提出一种非正交频谱共享方法，将NOMA的基本思想扩展应用到包括一个或者多个小区的无线通信系统，尤其是认知无线电系统之中，以解决上述技术问题中的至少一个。

具体实施方式
现在参考附图来更加充分地描述本公开的例子。以下描述实质上只是示例性的，而不旨在限制本公开、应用或用途。

本公开所涉及的UE(User Equipment，用户设备)包括但不限于移动终端、计算机、车载设备等具有无线通信功能的终端。进一步，取决于具体所描述的功能，本公开所涉及的UE还可以是UE本身或其中的部件如芯片。此外，类似地，本公开中所涉及的基站可以例如是eNB或者是eNB中的部件如芯片。进而，本公开的技术方案例如可以用于FDD(Frequency Division Duplexing，频分双工)系统和TDD(Time Division Duplexing，时分双工)系统。
图1(a)是图示根据本公开的实施例的非正交频谱共享的一个场景的示意图。如图1(a)所示，在无线通信系统中存在一个小区，该小区的服务基站为BS，在这个小区中存在第一用户设备SU1和第二用户设备SU2。在BS与用户设备之间进行数据传输时，由于用户设备会接收到BS发送给其他用户设备的数据，这样导致产生对用户设备的数据干扰。用户设备向BS发送数据时同样会遇到类似的干扰问题。以下行传输为例，当BS向SU1发送数据时，SU1可能会接收到BS向SU2发送的下行数据，因此BS向SU2发送的下行数据对SU1造成了干扰。
如果用h1表示BS和SU1之间的信道系数，h2表示BS和SU2之间的信道系数，。s1表示SU1的下行信号，s2表示SU2的下行信号，x1表示SU1的上行信号，x2表示SU2的上行信号。则在下行传输中，SU1接收到的信号ySU1和SU2接收到的信号ySU2分别为：
Figure PCTCN2017070125-appb-000001
Figure PCTCN2017070125-appb-000002
类似地，在上行传输中，BS接收到的信号yBS为：
yBS＝x1*h1+x2*h2           (3)
由此可见，在具有一个小区的无线通信系统(单系统)中的上行传输中，有用信号和干扰信号经过不同的信道到达接收端；而在下行传输中，有用信号和干扰信号经过相同的信道到达接收端。
为避免不同用户设备之间的数据干扰，不同用户设备之间可以使用不同频谱或不同功率进行传输。为此，在这个场景中，可以使用NOMA来实现非正交频谱共享。以下行传输为例，BS的发射机采用相同的频谱不同的功率来向SU1和SU2发送数据，并将信道信息h1和h2发送给SU1和SU2。例如，BS采用高功率向SU1发送数据，以低功率向SU2发送数据。在接收端，SU1直接解调出数据信号，而SU2首先解调出干扰信号，从而确定出数据信号。上行传输的过程类似。在SU1和SU2进行数据解调的过程中，只有当数据信号和干扰信号的差异足够大，使得在接收端接收到的数据信号和/或干扰信号能够满足解调要求，才能够保证SU1和SU2能够正确地解调出数据信号和干扰信号。
波形参数是分配给发射机的滤波器参数，其与功率调整因子一样，都是发射端的参数，能够影响发射端生成信号的功率。因此，如果能够合理地调整发射端的波形参数，使得在接收端接收到的信号差异足够大，那么接收端就能够正确解调出数据信号。
也就是说，在单系统中，通过合理地设置发射端的参数，例如波形参数和/或功率调整因子，可以为位于同一个小区中的不同用户设备分配相同的频谱资源，从而实现频谱资源共享。
图1(b)是图示根据本公开的实施例的非正交频谱共享的另一个场景的示意图。
如图1(b)所示，在无线通信系统中存在两个相邻的小区：第一小 区SS1和第二小区SS2，小区SS1的基站为BS1，小区SS2的基站为BS2，在小区SS1中存在第一用户设备SU1，在小区SS2中存在第二用户设备SU2，用户SU1和SU2都位于各自所在小区的边缘。SU1可以与BS1进行上下行的传输，SU2可以与BS2进行上下行的传输。
在下行传输过程中，BS1向SU1发送数据信号，BS2向SU2发送数据信号。在这个过程中，由于SU1和SU2位于小区边缘，因此SU1会接收到来自BS2的干扰信号，SU2也会接收到来自BS1的干扰信号。假定BS1与SU1之间的信道系数为h1,1，BS2与SU2之间的信道系数为h2,2，BS1与SU2之间的信道系数为h2,1，BS2与SU1之间的信道系数为h1,2，用S1表示BS1的下行数据信号，S2表示BS2的下行数据信号，ySU1表示SU1接收到的信号，ySU2表示SU2接收到的信号，则有下述公式：

Figure PCTCN2017070125-appb-000004
在上行传输过程中，SU1向BS1发送数据信号，SU2向BS2发送数据信号。在这个过程中，由于SU1和SU2位于小区边缘，因此BS2会接收到来自SU1的干扰信号，BS1也会接收到来自SU2的干扰信号。假定BS1与SU1之间的信道系数为h1,1，BS2与SU2之间的信道系数为h2,2，BS1与SU2之间的信道系数为h2,1，BS2与SU1之间的信道系数为h1,2，用x1表示SU1的上行数据信号，x2表示SU2的上行数据信号，yBS1表示BS1接收到的信号，yBS2表示BS2接收到的信号，则有下述公式：
Figure PCTCN2017070125-appb-000005
Figure PCTCN2017070125-appb-000006
与单系统的情况类似，在具有多个小区的无线通信系统(多系统)中，如果能够合理地调整发射端的参数，例如波形参数或者功率调整因子，使得在接收端接收到的数据信号和干扰信号的差异满足解调要求，那么SU1和SU2就可以使用相同的频谱资源。
针对以上技术问题，提出了根据本公开的技术方案。图2图示了根据本公开的实施例的无线通信系统中的电子设备200的结构。
如图2所示，电子设备200可以包括处理电路210。需要说明的是，电子设备200既可以包括一个处理电路210，也可以包括多个处理电路210。另外，电子设备200还可以包括作为收发机的通信单元220等。
进一步，处理电路210可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
例如，如图2所示，处理电路210可以包括获取单元211、设置单元212和分配单元213。
在如图2所示的电子设备200中，获取单元211可以获取电子设备所在的无线通信系统中的第一用户设备的位置信息和波形参数信息以及电子设备所在的无线通信系统中的第二用户设备的频谱资源信息。
基于第一用户设备的位置信息和波形参数信息，设置单元212可以设置波形参数。
分配单元213可以将第二用户设备的频谱资源分配给第一用户设备，以便第一用户设备基于设置的波形参数使用第二用户设备的频谱资源。
根据本公开的实施例，电子设备200的获取单元211可以采用本领域各种公知的方法来获取用户设备的位置信息，例如，如果第一用户设备是第一次接入系统的新用户设备，第一用户设备可以主动或者被动地上报位置信息；如果第一用户设备是系统中已有的用户设备，第一用户设备可以主动或者被动地更新位置信息。此外，获取单元211还可以从电子设备200中(例如存储单元，未示出)或者从其它电子设备中获取用户设备的频谱资源信息。进一步，获取单元211可以通过电子设备200的通信单元220来获取上述信息，并可以将获取的第一用户设备的位置信息发送到设置单元212，并将获取的第二用户设备的频谱资源信息发送到分配单元213。
根据本公开的实施例，设置单元212可以从获取单元211来获取第一用户设备的位置信息，并可以根据一定的算法或者规则来设置波形参数。这里，设置波形参数包括设置第一用户设备的波形参数以及设置第二用户设备的波形参数。进一步，设置单元212可以将设置好的波形参数发 送到通信单元220以便通知第一用户设备和第二用户设备。根据本公开的实施例，设置的波形参数使得在第一用户设备和第二用户设备进行数据传输的过程中接收端可以正确解调出数据，也就是说，在下行传输中第一用户设备和第二用户设备都能够正确解调出数据，在上行传输中为用户设备服务的基站能够正确解调出数据。
在本公开中，当无线通信系统采用FBMC(Filter Bank Multicarrier，滤波器组多载波)技术时，波形参数可以是滤波器的混叠因子。但是本领域技术人员应当理解，波形参数可以是本领域中任何一种发射端的波形参数。根据本公开的实施例，电子设备200的获取单元211可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。这里，可以当用户设备第一次接入系统时，上报用户设备的波形参数信息，可以与位置信息一起上报波形参数信息，也可以与位置信息分开上报波形参数信息。
根据本公开的实施例，分配单元213可以将第二用户设备的频谱资源分配给第一用户设备。这里，分配单元213可以将分配给第一用户设备的频谱资源发送到通信单元220以便通知第一用户设备。
采用根据本公开的电子设备200，通过设置波形参数，无线通信系统中的不同的用户设备可以使用相同的频谱资源，实现非正交频谱资源共享，提高了频谱的利用率。
值得注意的是，根据本公开的实施例，电子设备200可以应用于如图1(a)所示的场景中(即单系统的场景)，即无线通信系统可以只包括第一小区，第一用户设备和第二用户设备都位于第一小区中。在这个场景中，电子设备200可以为第一小区中的基站。根据本公开的实施例，电子设备200也可以应用于如图1(b)所示的场景中(即多系统的场景)，即无线通信系统可以至少包括第一小区和第二小区，第一用户设备位于第一小区中，第二用户设备位于第二小区中。
根据本公开的实施例，处理电路210中的获取单元211还可以获取第二用户设备的位置信息，并基于第一用户设备的位置信息和波形参数信息以及第二用户设备的位置信息设置波形参数。
根据本公开的实施例，处理电路210中的获取单元211还可以获取 第一用户设备的传输模式信息，并基于第一用户设备和第二用户设备的位置信息以及第一用户设备的传输模式信息来设置波形参数。这里，第一用户设备的传输模式信息可以包括上行传输和下行传输。也就是说，当传输模式信息为上行传输时，表明第一用户设备即将执行上行传输；当传输模式信息为下行传输时，表明第一用户设备即将执行下行传输。
在这个实施例中，电子设备200的获取单元211可以采用本领域各种公知的方法来获取用户设备的传输模式信息，例如，如果第一用户设备是第一次接入系统的新用户设备，第一用户设备可以主动或者被动地上报传输模式信息；如果第一用户设备是系统中已有的用户设备，第一用户设备可以主动或者被动地更新传输模式信息。
根据本公开的实施例，分配单元213可以将第二用户设备的频谱资源分配给第一用户设备，以便第一用户设备基于设置的波形参数使用第二用户设备的频谱资源。这个，第二用户设备是与第一用户设备的传输模式相同的用户设备。例如，当第一用户设备的传输模式信息是上行传输时，选择同样是上行传输的第二用户设备，并将其频谱资源分配给第一用户设备；当第一用户设备的传输模式信息是下行传输时，选择同样是下行传输的第二用户设备，并将其频谱资源分配给第一用户设备。
根据本公开的实施例，处理电路210的设置单元212还可以基于第一用户设备和第二用户设备的位置信息设置功率调整因子。处理电路210的分配单元213获取第二用户设备的频谱资源信息，将第二用户设备的频谱资源分配给第一用户设备，以便第一用户设备基于设置的波形参数和功率调整因子使用第二用户设备的频谱资源。
在这个实施例中，电子设备200不仅能够设置用户设备的波形参数，还能够设置用户设备的功率调整因子。这里，设置功率调整因子包括设置第一用户设备的功率调整因子以及设置第二用户设备的功率调整因子。进一步，设置单元212可以将设置好的功率调整因子发送到通信单元220以便通知第一用户设备和第二用户设备。根据本公开的实施例，设置的功率调整因子使得在第一用户设备和第二用户设备进行数据传输的过程中接收端可以正确解调出数据，也就是说，在下行传输中第一用户设备和第二用户设备都能够正确解调出数据，在上行传输中为用户设备服务的基站能够正确解调出数据。
在这个实施例中，基于第一用户设备和第二用户设备的位置信息，电子设备200的设置单元212还可以设置第一用户设备和第二用户设备的 解调次数信息，并且可以通过通信单元220将第一用户设备和第二用户设备的解调次数信息随着各自的波形参数和/或功率调整因子一起分别发送到第一用户设备和第二用户设备。这里，解调次数信息包括一次解调和两次解调。一次解调表明第一次解调出来的就是用户设备所需的数据信号；两次解调表明第一次解调出来的是干扰信号，第二次解调出来的是用户设备所需的数据信号。当用户设备收到解调次数信息后，可以根据解调次数信息确定需要一次解调还是两次解调。
下面将详细描述应用于多系统场景中的电子设备200。
在多系统场景中，无线通信系统至少包括第一小区和第二小区，第一用户设备位于第一小区中，并且第二用户设备位于第二小区中。
值得注意的是，本公开中的无线通信系统可以为认知无线电通信系统，第一小区可以为第一次系统，第二小区可以为第二次系统，电子设备200可以为核心网中的频谱协调器。在这个无线通信系统中，第一小区中的用户设备可以通过第一小区中的基站与频谱协调器进行通信，第二小区中的用户设备可以通过第二小区中的基站与频谱协调器进行通信。根据本公开的实施例，电子设备200也可以是无线通信系统中的基站，例如第一小区中的基站。在这种情况下，第一小区中的用户设备直接与电子设备200进行通信，第二小区中的用户设备通过第二小区中的基站与电子设备200进行通信。
根据本公开的实施例，第一用户设备处于第一小区中的特定区域，在特定区域之内，第一用户设备受到第二小区的干扰信息。这里，第一小区中的特定区域是一个区域，在这个区域中的用户设备的接收信号质量不满足解调要求，即在这个区域中的用户设备受到来自其他小区的用户设备的干扰而不能正确地解调数据。同样地，在第二小区中也存在特定区域，在第二小区中的特定区域中的用户设备的接收信号质量不满足解调要求，即在这个区域中的用户设备受到来自其他小区(例如第一小区)的用户设备的干扰而不能正确地解调数据。如图1所示，虚线所示的区域为小区SS1和SS2的强干扰区域，在这个区域中的用户SU1遭受来自小区SS2的干扰较强，用户SU2遭受来自小区SS1的干扰较强，因此，在本公开中，定义第一小区中位于虚线区域内的区域为第一小区中的特定区域，定义第二小区中位于虚线区域内的区域为第二小区中的特定区域。
根据本公开的实施例，当小区SS1和SS2所在的无线通信系统中存在可用的空闲频谱时，分配单元213可以将空闲的频谱分配给第一用户设 备；当小区SS1和SS2所在的无线通信系统中没有可用的空闲频谱时，电子设备200(例如判断单元，未示出)可以判断第一用户设备是否处于第一小区中的特定区域，如果第一用户设备没有处于第一小区中的特定区域，那么分配单元213可以将第二小区中处于第二小区中的特定区域之外的与第一用户设备的传输模式信息相同的第三用户设备的频谱资源分配给第一用户设备。这是因为当第一用户设备没有处于第一小区中的特定区域时，说明第一用户设备距离第二小区较远，而第二小区中处于第二小区的特定区域之外的第三用户设备距离第一小区也较远，因此即便第一用户设备与第三用户设备采用相同的频谱资源，由于信道的衰减，也不会产生很大的干扰，在接收端能够正确解调出数据信号的概率很大。
根据本公开的实施例，当小区SS1和SS2所在的无线通信系统中没有可用的空闲频谱，并且第一用户设备处于第一小区中的特定区域时，那么分配单元213可以将与第一用户设备的传输模式信息相同的第二用户设备的频谱资源分配给第一用户设备。这里，第二用户设备为位于第二小区中任意位置的与第一用户设备的传输模式信息相同的用户设备。通过设置单元212为第一用户设备和第二用户设备分配合适的波形参数和功率调整因子中的至少一个，使得第一用户设备和第二用户设备也能够正确地解调出数据信号。
根据本公开的实施例，处理电路220进一步被配置为基于第一用户设备的位置信息来确定第一用户设备是否处于第一小区的特定区域之内。
图3是图示根据本公开的实施例的确定强干扰区域的场景的示意图。以SU1的下行传输为例，假定SU1距离BS1的距离为d1,1，SU1距离BS2的距离为d1,2，BS1与SU1之间的信道系数为h1,1，BS2与SU1之间的信道系数为h1,2，α1表示SU1接收到的数据信号的信道系数与干扰信号的信道系数的比值，这里只考虑了路径损耗的影响，而信道系数和距离成反比，因此有下述公式成立：
Figure PCTCN2017070125-appb-000007
其中，α1≥1。假定BS1和BS2的发射功率相同，那么SU1的用信干比表示的接收信号质量SIRSU1如下所示：
Figure PCTCN2017070125-appb-000008
当SU1的接收信号质量不满足解调要求，即小于解调门限时，可以判定SU1处于第一小区的特定区域。当SU1的SIR不满足解调门限时，有下式成立：
Figure PCTCN2017070125-appb-000009
也就是说，
Figure PCTCN2017070125-appb-000010
其中，γ1是SU1的解调门限。这里，不同的用户设备的解调门限不同，因此根据本公开的实施例，当用户设备第一次接入该无线通信系统中时，可以上报该用户设备的解调门限。此外，用户设备可以与位置信息一起上报解调门限，也可以与位置信息分开上报解调门限。
在本公开的实施例中，解调门限可以用SIR(Signal to Interference Ratio，信干比)、SINR(Signal to Interference plus Noise Ratio，信干噪比)或者SNR(Signal Noise Ratio，信噪比)中的一种或多种来表示。公式(9)采用了SIR来表示SU1接收信号的质量，因此γ1可以是用SIR表示的解调门限，而对于用其它参数表示的解调门限的情况是类似的。
根据本公开的实施例，当电子设备200的获取单元211获取了第一用户设备的位置信息时，电子设备200(例如判断单元，未示出)可以确定SU1距离BS1的距离d1,1以及SU1距离BS2的距离d1,2，并根据公式(10)来确定SU1是否位于第一小区的特定区域。
根据本公开的另一个实施例，当电子设备200的获取单元211获取了第一用户设备的位置信息时，电子设备200(例如信道信息获取单元，未示出)可以从位于电子设备200上或者位于电子设备200以外的设备上的数据库获取信道信息，包括BS1与SU1之间的信道系数h1,1以及BS2与SU1之间的信道系数h1,2，然后电子设备200(例如判断单元，未示出)可以根据公式(10)来确定SU1是否位于第一小区的特定区域。
下面将详细说明应用于多系统场景中的电子设备200如何设置第一用户设备和第二用户设备的波形参数和功率调整因子。
第一实施例
在第一实施例中，第一用户设备与第二用户设备位于不同的小区中，假定第一用户设备的传输模式信息为下行传输。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：基于第一用户设备和第二用户设备的位置信息获取信道信息；以及基于信道信息，按照接收端的解调的信干噪比要求或信噪比要求设置功率调整因子。
图4是图示根据本公开的实施例的配置功率调整因子的过程的示意图。
如图4所示，设置单元212首先计算α1和α2的值。
当电子设备200的获取单元211获取了第一用户设备和第二用户设备的位置信息时，电子设备200(例如信道信息获取单元，未示出)可以从位于电子设备200上或者位于电子设备200以外的设备上的数据库获取信道信息，包括BS1与SU1之间的信道系数h1,1，BS2与SU2之间的信道系数h2,2，BS1与SU2之间的信道系数h2,1和BS2与SU1之间的信道系数h1,2，然后设置单元212可以根据公式(8)来计算α1的值，并根据下述公式(12)来计算SU2接收到的数据信号的信道系数与干扰信号的信道系数的比值α2的值。
Figure PCTCN2017070125-appb-000011
其中，α2≥1，d2,1表示SU2距离BS1的距离，d2,2表示SU2距离BS2的距离，h2,1表示BS1与SU2之间的信道系数，h2,2表示BS2与SU2之间的信道系数，这里只考虑了路径损耗的影响。与前面说明的过程类似，如果用γ2表示SU2的解调门限，当SU2的SIR不满足解调门限时，有下式成立：
Figure PCTCN2017070125-appb-000012
然后设置单元212可以比较α1和α2的大小。
α1>α2
当α1>α2时，说明与SU1相比，SU2距离强干扰区域的中心更近一些，因此遭受的干扰更强一些。也就是说，SU1直接解调出数据信号，而SU2先解调出干扰信号，再解调出数据信号。如果用SNR2,2表示SU2接收到的BS2的数据信号的信噪比，p2表示SU2的功率调整因子，h2,2表示BS2与SU2之间的信道系数，N0表示白噪声，γ2表示SU2的解调门限，那么只有当SU2接收到的数据信号的信噪比大于或者等于SU2的解调门限时 才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000013
则由上述公式(14)可以计算出SU2的功率调整因子p2为：
Figure PCTCN2017070125-appb-000014
如果用SINR2,1表示SU2接收到的BS1的干扰信号的信干噪比，p1 (1)表示SU1的第一功率调整因子，h2,1表示BS1与SU2之间的信道系数，h2,2表示BS2与SU2之间的信道系数，N0表示白噪声，p2表示由公式(15)计算出的SU2的功率调整因子，γ1表示SU1的解调门限，那么只有当SU2接收到的干扰信号的信干噪比大于或者等于SU1的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000015
则由上述公式(16)可以计算出SU1的第一功率调整因子p1 (1)为：
Figure PCTCN2017070125-appb-000016
如果用SINR1,1表示SU1接收到的BS1的数据信号的信干噪比，p1 (2)表示SU1的第二功率调整因子，h1,2表示BS2与SU1之间的信道系数，h1,1表示BS1与SU1之间的信道系数，N0表示白噪声，p2表示由公式(15)计算出的SU2的功率调整因子，γ1表示SU1的解调门限，那么只有当SU1接收到的数据信号的信干噪比大于或者等于SU1的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000017
则由上述公式(18)可以计算出SU1的第二功率调整因子p1 (2)为：
Figure PCTCN2017070125-appb-000018
然后，设置单元212根据公式(17)和公式(19)得出的第一功率调整因子和第二功率调整因子来设置SU1的功率调整因子p1为：
Figure PCTCN2017070125-appb-000019
由此，当α1>α2时，设置单元212经过两个步骤求解出了SU1的功率调整因子p1，并经过一个步骤求解出了SU2的功率调整因子p2。
α1≤α2
当α1≤α2时，说明与SU2相比，SU1距离强干扰区域的中心更近一些，因此遭受的干扰更强一些。也就是说，SU2直接解调出数据信号，而SU1先解调出干扰信号，再解调出数据信号。如果用SNR1,1表示SU1接收到的BS1的数据信号的信噪比，p1表示SU1的功率调整因子，h1,1表示BS1与SU1之间的信道系数，N0表示白噪声，γ1表示SU1的解调门限，那么只有当SU1接收到的数据信号的信噪比大于或者等于SU1的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000020
则由上述公式(21)可以计算出SU1的功率调整因子p1为：
Figure PCTCN2017070125-appb-000021
如果用SINR1,2表示SU1接收到的BS2的干扰信号的信干噪比，p2 (1)表示SU2的第一功率调整因子，h1,2表示BS2与SU1之间的信道系数，h1,1表示BS1与SU1之间的信道系数，N0表示白噪声，p1表示由公式(22)计算出的SU1的功率调整因子，γ2表示SU2的解调门限，那么只有当SU1接收到的干扰信号的信干噪比大于或者等于SU2的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000022
则由上述公式(23)可以计算出SU2的第一功率调整因子p2 (1)为：
Figure PCTCN2017070125-appb-000023
如果用SINR2,2表示SU2接收到的BS2的数据信号的信干噪比，p2 (2)表示SU2的第二功率调整因子，h2,1表示BS1与SU2之间的信道系数，h2,2表示BS2与SU2之间的信道系数，N0表示白噪声，p1表示由公式(22)计算出的SU1的功率调整因子，γ2表示SU2的解调门限，那么只有当SU2接收到的数据信号的信干噪比大于或者等于SU2的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000024
则由上述公式(25)可以计算出SU2的第二功率调整因子p2 (2)为：
Figure PCTCN2017070125-appb-000025
然后，设置单元212根据公式(24)和公式(26)得到的第一功率调整因子和第二功率调整因子来设置SU2的功率调整因子p2为：
Figure PCTCN2017070125-appb-000026
由此，当α1≤α2时，设置单元212经过两个步骤求解出了SU2的功率调整因子p2，并经过一个步骤求解出了SU1的功率调整因子p1。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：确定设置的功率调整因子已超过了发送端的功率放大器的调整范围；重新设置功率调整因子，使得重新设置的功率调整因子处于发送端的功率放大器的调整范围之内；获取第一用户设备和第二用户设备的波形参数信息；以及设置第一用户设备和第二用户设备的波形参数，使得接收端的解调的信干噪比要求或信噪比要求被满足。
发送端的功率放大器都有其调整的范围，当设置单元212根据上面描述的步骤求解出SU2的功率调整因子p2和SU1的功率调整因子p1后，发现某个功率调整因子超过了发送端功率放大器的调整范围，那么需要重新设置功率调整因子。例如，当求解出的功率调整因子小于功率放大器的最小功率调整因子时，重新设置功率调整因子为功率放大器的最小功率调 整因子；当求解出的功率调整因子大于功率放大器的最大功率调整因子时，重新设置功率调整因子为功率放大器的最大功率调整因子。
根据本公开的实施例，在设置单元212重新设置了功率调整因子之后，还可以设置第一用户设备和第二用户设备的波形参数。以滤波器的混叠因子K为例，K可以取值为1，2，3或者4。当K取值为1时，生成的发射信号功率最小；当K取值为4时，生成的发射信号功率最大。
当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数，使得接收端的解调的信干噪比要求或信噪比要求被满足。
根据本公开的实施例，当α1>α2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值；当α1≤α2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值。
如前文所述，基于第一用户设备和第二用户设备的位置信息，设置单元212还可以设置第一用户设备和第二用户设备的解调次数信息，并且可以通过通信单元220将第一用户设备和第二用户设备的解调次数信息随着各自的波形参数和/或功率调整因子一起分别发送到第一用户设备和第二用户设备。例如，当α1≤α2时，第一用户设备的解调次数信息为两次解调，第二用户设备的解调次数信息为一次解调；当α1>α2时，第一用户设备的解调次数信息为一次解调，第二用户设备的解调次数信息为两次解调。
如上所述，在第一实施例中，当第一用户设备的传输模式信息为下行传输时，设置单元212可以为第一用户设备和第二用户设备设置功率调整因子的值；当功率调整因子超过了发送端的功率放大器的调整范围时，设置单元212还可以设置波形参数的值。以这种方式，使得在接收端能够正确解调出数据信号，实现了频谱的非正交共享。
第二实施例
在第二实施例中，第一用户设备与第二用户设备位于不同的小区中， 假定第一用户设备的传输模式信息为下行传输。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：基于第一用户设备和第二用户设备的位置信息获取信道信息；获取第一用户设备和第二用户设备的波形参数信息；以及基于信道信息和波形参数信息，设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。
根据本公开的实施例，设置单元212首先需要计算α1和α2的值，并比较α1和α2的大小。这个过程与第一实施例中相同，在此不再赘述，即设置单元212可以根据公式(8)来计算α1的值，并根据公式(12)来计算α2的值。
根据本公开的实施例，电子设备200(例如波形参数信息获取单元，未示出)可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。

第三实施例
在第三实施例中，第一用户设备和第二用户设备位于不同的小区中，假定第一用户设备的传输模式信息为上行传输。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作： 基于第一用户设备和第二用户设备的位置信息获取信道信息；以及基于信道信息，按照接收端的解调的信干噪比要求或信噪比要求设置功率调整因子。

发送端的功率放大器都有其调整的范围，当设置单元212根据上面描述的步骤求解出SU2的功率调整因子p2和SU1的功率调整因子p1后，发现某个功率调整因子超过了发送端功率放大器的调整范围，那么需要重新设置功率调整因子。例如，当求解出的功率调整因子小于功率放大器的最小功率调整因子时，重新设置功率调整因子为功率放大器的最小功率调整因子；当求解出的功率调整因子大于功率放大器的最大功率调整因子时，重新设置功率调整因子为功率放大器的最大功率调整因子。
根据本公开的实施例，在设置单元212重新设置了功率调整因子之后，还可以设置第一用户设备和第二用户设备的波形参数。以滤波器的混 叠因子K为例，K可以取值为1，2，3或者4。当K取值为1时，生成的发射信号功率最小；当K取值为4时，生成的发射信号功率最大。
根据本公开的实施例，电子设备200(例如波形参数信息获取单元，未示出)可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。这里，可以当用户设备第一次接入系统时，上报用户设备的波形参数信息，可以与位置信息一起上报波形参数信息，也可以与位置信息分开上报波形参数信息。当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数，使得接收端的解调的信干噪比要求或信噪比要求被满足。

根据本公开的实施例，设置单元212首先需要计算β1和β2的值，并比较β1和β2的大小。这个过程与第三实施例中相同，在此不再赘述，即设置单元212可以根据公式(42)来计算β1的值，并根据公式(43)来计算β2的值。
根据本公开的实施例，电子设备200(例如波形参数信息获取单元，未示出)可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。
根据本公开的实施例，当β1>β2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值；当β1≤β2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：确定设置的波形参数无法满足接收端的解调的信干噪比要求或信噪比要求；以及基于信道信息，进一步设置功率调整因子，以满足接收端的解调的信干噪比要求或信噪比要求。
前文中提到，波形参数，例如混叠因子具有一定的取值范围，所以存在无论如何调整波形参数都无法满足接收端的解调要求的情况。因而处理电路210(例如判断单元，未示出)可以被配置为在配置波形参数之后 判断设置的波形参数是否满足接收端的解调的信干噪比要求或信噪比要求，如果不满足解调要求，需要进一步设置功率调整因子。这里，仍然可以定义归一化发射信号功率，例如定义当K为4时生成的发射信号功率与K＝1时生成的发射信号功率的比值k3作为K为4时的归一化发射信号功率。这部分内容与第二实施例相同，在此不再赘述。

图5是图示根据本公开的实施例的多系统中非正交频谱共享的过程的示意图。如图5所示，当新用户接入系统时，需要上报位置信息，已有的用户可以周期性或者事件性的上报当前更新的位置信息。这里，新用户接入系统时还可以上报其传输模式信息和波形参数信息，已有的用户还可以周期性或者事件性的上报当前更新的传输模式信息。接下来，电子设备200可以判断是否有可用的空闲频谱，如果有，那么可以将可用的空闲频谱直接分配给新用户。如果没有可用的空闲频谱，那么电子设备200可以判断新用户是否位于强干扰区域，如果新用户没有位于强干扰区域，那么电子设备200可以将相邻系统的强干扰区域之外的与新用户的传输模式相同的用户的频谱分配给新用户设备。如果新用户位于强干扰区域，继续判断新用户的传输模式信息是上行传输还是下行传输，然后电子设备200将相邻系统的与新用户的传输模式相同的用户的频谱分配给新用户设备，获取信道信息，并根据本公开的实施例来设置解调次数信息以及波形参数和/或功率调整因子。
根据本公开的实施例，可以以新用户接入为触发事件来执行根据本公开的实施例所示的方法。换句话说，每当有新用户接入系统时，按照图 5所示来执行频谱的分配和参数的设置过程。从一个新用户接入系统到下一个新用户接入系统之间，不改变第一小区和第二小区中所有用户设备的频谱信息、波形参数以及功率调整因子。根据本公开的另一个实施例，也可以根据需要来执行根据本公开的实施例所示的方法。也就是说，当需要为某个小区中的某个用户设备分配频谱或者设置波形参数和/或功率调整因子时，根据本公开的实施例来执行相应的方法。
图6是图示根据本公开的实施例的多系统中非正交频谱共享的信令交互的过程的示意图。如图6所示，当SS1小区中的新用户接入系统时，新用户上报位置信息和传输模式信息，并根据需要还可以上报波形参数信息和/或解调门限，SS2小区中已有的用户可以更新当前的位置信息和传输模式信息。接下来，SC(Spectrum Coordinator，频谱协调器)可以判断是否有可用的空闲频谱，如果有，那么可以将可用的空闲频谱直接分配给新用户。如果没有可用的空闲频谱，那么SC可以判断新用户是否位于强干扰区域，如果新用户没有位于强干扰区域，那么SC可以将相邻系统的强干扰区域之外的与新用户的传输模式相同的用户的频谱分配给新用户设备。如果新用户位于强干扰区域，那么SC按照新用户的传输模式信息，并根据本公开的实施例中的预处理算法来设置解调次数信息以及波形参数和/或功率调整因子，获取信道信息，并将相邻系统的用户的频谱分配给新用户设备。接下来，SC将设置的解调次数信息以及波形参数和/或功率调整因子、信道参数和分配的频谱信息发送给小区SS1中的新用户设备，并将设置的解调次数信息、波形参数和/或功率调整因子和信道参数发送到小区SS2中的用户设备。
上面描述了应用于多系统场景中的电子设备200。下面将详细描述应用于单系统场景中的电子设备200。
前面提到，电子设备200还可以应用于例如图1(a)的单系统场景中。
根据本公开的实施例，在单系统中设置用户设备的波形参数和/或功率调整因子的方法包括：当小区中的新用户接入系统时，新用户(例如第一用户设备)上报位置信息以及即将执行的传输模式信息(这里，传输模式信息包括上行传输和下行传输)，并根据需要还可以上报波形参数信息和/或解调门限，小区中已有的用户可以更新当前的位置信息。接下来，SC可以判断是否有可用的空闲频谱，如果有，那么可以将可用的空闲频谱直接分配给新用户。如果没有可用的空闲频谱，那么SC根据本公开的 实施例中的预处理算法来设置解调次数信息以及波形参数和/或功率调整因子，获取信道信息，并将小区中的其他用户设备(例如第二用户设备)的频谱分配给新用户设备。接下来，SC将设置的解调次数信息、波形参数和/或功率调整因子、信道参数和分配的频谱信息发送给小区中的新用户设备，并将设置的解调次数信息、波形参数和/或功率调整因子以及信道参数发送到其他用户设备。

Figure PCTCN2017070125-appb-000077
由此，当h1>h2时，设置单元212经过两个步骤求解出了SU2的功率调整因子p2，并经过一个步骤求解出了SU1的功率调整因子p1。
h1≤h2
当h1≤h2时，SU2距离BS较近，SU1距离BS较远。也就是说，SU1直接解调出数据信号，而SU2先解调出干扰信号，再解调出数据信号。如果用SNR2表示SU2接收到的BS的数据信号的信噪比，p2表示SU2的功率调整因子，h2表示BS与SU2之间的信道系数，N0表示白噪声，γ2表示SU2的解调门限，那么只有当SU2接收到的数据信号的信噪比大于或者等于SU2的解调门限时才能正确解调出数据信号，因此有下式成立：

则由上述公式(79)可以计算出SU2的功率调整因子p2为：
Figure PCTCN2017070125-appb-000079
如果用SINR2表示SU2接收到的BS的干扰信号的信干噪比，p1 (1)表示SU1的第一功率调整因子，h2表示BS与SU2之间的信道系数，N0表示白噪声，p2表示由公式(80)计算出的SU2的功率调整因子，γ1表示SU1的解调门限，那么只有当SU2接收到的干扰信号的信干噪比大于或者等于SU1的解调门限时才能正确解调出数据信号，因此有下式成立：

发送端的功率放大器都有其调整的范围，当设置单元212根据上面描述的步骤求解出SU2的功率调整因子p2和SU1的功率调整因子p1后，发现某个功率调整因子超过了发送端功率放大器的调整范围，那么需要重新设置功率调整因子。例如，当求解出的功率调整因子小于功率放大器的最小功率调整因子时，重新设置功率调整因子为功率放大器的最小功率调整因子；当求解出的功率调整因子大于功率放大器的最大功率调整因子时，重新设置功率调整因子为功率放大器的最大功率调整因子。
根据本公开的实施例，在设置单元212重新设置了功率调整因子之后，还可以设置第一用户设备和第二用户设备的波形参数。以滤波器的混叠因子K为例，K可以取值为1，2，3或者4。当K取值为1时，生成的发射信号功率最小；当K取值为4时，生成的发射信号功率最大。
根据本公开的实施例，电子设备200(例如波形参数信息获取单元，未示出)可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。这里，可以当用 户设备第一次接入系统时，上报用户设备的波形参数信息，可以与位置信息一起上报波形参数信息，也可以与位置信息分开上报波形参数信息。当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数，使得接收端的解调的信干噪比要求或信噪比要求被满足。
根据本公开的实施例，当h1>h2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值；当h1≤h2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值。
在这个实施例中，基于第一用户设备和第二用户设备的位置信息，设置单元212还可以设置第一用户设备和第二用户设备的解调次数信息，并且可以通过通信单元220将第一用户设备和第二用户设备的解调次数信息随着各自的波形参数和/或功率调整因子一起分别发送到第一用户设备和第二用户设备。这个过程与第一实施例类似，在此不再赘述。
如上所述，在第五实施例中，当第一用户设备的传输模式信息为下行传输时，设置单元212可以为第一用户设备和第二用户设备设置功率调整因子的值；当功率调整因子超过了发送端的功率放大器的调整范围时，设置单元212还可以设置波形参数的值。以这种方式，使得在接收端能够正确解调出数据信号，实现了频谱的非正交共享。
第六实施例
在第六实施例中，第一用户设备和第二用户设备位于相同的小区，假定第一用户设备的传输模式信息为下行传输。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：基于第一用户设备和第二用户设备的位置信息获取信道信息；获取第一用户设备和第二用户设备的波形参数信息；以及基于信道信息和波形参数信息，设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。
根据本公开的实施例，设置单元212首先需要确定h1和h2的值， 并比较h1和h2的大小。这个过程与第五实施例中相同，在此不再赘述。

根据本公开的实施例，当h1>h2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值；当h1≤h2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：确定设置的波形参数无法满足接收端的解调的信干噪比要求或信噪比要求；以及基于信道信息，进一步设置功率调整因子，以满足接收端的解调的信干噪比要求或信噪比要求。
前文中提到，波形参数，例如混叠因子具有一定的取值范围，所以存在无论如何调整波形参数都无法满足接收端的解调要求的情况。因而处理电路210(例如判断单元，未示出)可以被配置为在配置波形参数之后判断设置的波形参数是否满足接收端的解调的信干噪比要求或信噪比要求，如果不满足解调要求，需要进一步设置功率调整因子。这里，仍然可以定义归一化发射信号功率，例如定义当K为4时生成的发射信号功率与K＝1时生成的发射信号功率的比值k3作为K为4时的归一化发射信号功率。这部分内容与第二实施例相同，在此不再赘述。

根据本公开的实施例，当h1>h2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值；当h1≤h2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备 的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值。
在这个实施例中，基于第一用户设备和第二用户设备的位置信息，设置单元212还可以设置第一用户设备和第二用户设备的解调次数信息，并且可以通过通信单元220将第一用户设备和第二用户设备的解调次数信息随着各自的波形参数和/或功率调整因子一起分别发送到第一用户设备和第二用户设备。这个过程与第一实施例类似，在此不再赘述。
如上所述，在第七实施例中，当第一用户设备的传输模式信息为上行传输时，设置单元212可以为第一用户设备和第二用户设备设置功率调整因子的值；当功率调整因子超过了发送端的功率放大器的调整范围时，设置单元212还可以设置波形参数的值。以这种方式，使得在接收端能够正确解调出数据信号，实现了频谱的非正交共享。
第八实施例
在第八实施例中，第一用户设备和第二用户设备位于相同的小区，假定第一用户设备的传输模式信息为上行传输。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：基于第一用户设备和第二用户设备的位置信息获取信道信息；获取第一用户设备和第二用户设备的波形参数信息；以及基于信道信息和波形参数信息，设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。
根据本公开的实施例，设置单元212首先需要确定h1和h2的值，并比较h1和h2的大小。这个过程与第五实施例中相同，在此不再赘述。
根据本公开的实施例，电子设备200(例如波形参数信息获取单元，未示出)可以获取第一用户设备和第二用户设备的波形参数信息。波形参数信息可以包括用户设备可以采用的波形参数的范围，例如混叠因子的范围，也可以包括用户设备当前所采用的波形参数，例如混叠因子的值等，还可以包括用户设备是否可以进行波形参数调整的信息。当电子设备200获取了用户设备的波形参数信息后，可以设置第一用户设备和第二用户设备的波形参数以满足接收端的解调的信干噪比要求或信噪比要求。
根据本公开的实施例，当h1>h2时，设置单元212设置第一用户设备的混叠因子K1大于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最大的混叠因子的值， 将K2设置成第二用户设备的混叠因子的范围中最小的混叠因子的值；当h1≤h2时，设置单元212设置第一用户设备的混叠因子K1小于第二用户设备的混叠因子K2的值。例如，设置单元212将K1设置成第一用户设备的混叠因子的范围中最小的混叠因子的值，将K2设置成第二用户设备的混叠因子的范围中最大的混叠因子的值。
根据本公开的实施例，处理电路210进一步被配置为执行以下操作：确定设置的波形参数无法满足接收端的解调的信干噪比要求或信噪比要求；以及基于信道信息，进一步设置功率调整因子，以满足接收端的解调的信干噪比要求或信噪比要求。
前文中提到，波形参数，例如混叠因子具有一定的取值范围，所以存在无论如何调整波形参数都无法满足接收端的解调要求的情况。因而处理电路210(例如判断单元，未示出)可以被配置为在配置波形参数之后判断设置的波形参数是否满足接收端的解调的信干噪比要求或信噪比要求，如果不满足解调要求，需要进一步设置功率调整因子。这里，仍然可以定义归一化发射信号功率，例如定义当K为4时生成的发射信号功率与K＝1时生成的发射信号功率的比值k3作为K为4时的归一化发射信号功率。这部分内容与第二实施例相同，在此不再赘述。
下面将具体说明如何设置功率调整因子。

当h1>h2时，前文中提到，SU1的混叠因子K1大于SU2的混叠因子K2，这里假定K1＝4，K2＝1。
当h1>h2时，说明SU2距离BS较远，SU1距离BS较近。也就是说，BS先解调出来自SU1的信号，再解调出来自SU2的信号。如果用SNR2表示BS接收到的SU2的数据信号的信噪比，p2表示SU2的功率调整因子，h2表示BS与SU2之间的信道系数，N0表示白噪声，γ2表示SU2的解调门限，那么只有当BS接收到的SU2的数据信号的信噪比大于或者等于SU2的解调门限时才能正确解调出数据信号，因此有下式成立：

则由上述公式(108)可以计算出SU2的功率调整因子p2为：

则由上述公式(110)可以计算出SU1的功率调整因子p1为：

h1≤h2
当h1≤h2时，前文中提到，SU1的混叠因子K1小于SU2的混叠因子K2，这里假定K1＝1，K2＝4。
当h1≤h2时，SU2距离BS较近，SU1距离BS较远。也就是说，BS先解调出来自SU2的信号，再解调出来自SU1的信号。如果用SNR1表示BS接收到的SU1的数据信号的信噪比，p1表示SU1的功率调整因子，h1表示BS与SU1之间的信道系数，N0表示白噪声，γ1表示SU1的解调门限，那么只有当BS接收到的SU1的数据信号的信噪比大于或者等于SU1的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000111
则由上述公式(112)可以计算出SU1的功率调整因子p1为：
Figure PCTCN2017070125-appb-000112
如果用SINR2表示BS接收到的SU2的数据信号的信干噪比，p2表示SU2的功率调整因子，h2表示BS与SU2之间的信道系数，h1表示BS 与SU1之间的信道系数，N0表示白噪声，p1表示由公式(111)计算出的SU1的功率调整因子，γ2表示SU2的解调门限，k3表示K为4时的归一化发射信号功率，那么只有当BS接收到的SU2的数据信号的信干噪比大于或者等于SU2的解调门限时才能正确解调出数据信号，因此有下式成立：
Figure PCTCN2017070125-appb-000113
则由上述公式(114)可以计算出SU2的功率调整因子p2为：
Figure PCTCN2017070125-appb-000114
在这个实施例中，基于第一用户设备和第二用户设备的位置信息，设置单元212还可以设置第一用户设备和第二用户设备的解调次数信息，并且可以通过通信单元220将第一用户设备和第二用户设备的解调次数信息随着各自的波形参数和/或功率调整因子一起分别发送到第一用户设备和第二用户设备。这个过程与第一实施例类似，在此不再赘述。
如上所述，在第八实施例中，当第一用户设备的传输模式信息为上行传输时，设置单元212可以为第一用户设备和第二用户设备设置波形参数的值；当波形参数无法满足接收端的解调要求时，设置单元212还可以设置功率调整因子的值。以这种方式，使得在接收端能够正确解调出数据信号，实现了频谱的非正交共享。
