Wi-Fi 6（原称：802.11.ax）即第六代无线网络技术，是Wi-Fi标准的名称。是Wi-Fi联盟创建于IEEE 802.11标准的无线局域网技术。Wi-Fi 6将允许与多达8个设备通信，最高速率可达9.6Gbps。
802.11AX协议规定的OFDMA(Orthogonal Frequency Division Multiple Access，正交频分多址)技术可实现多个无线终端同时传输，在实际使用场景中，一个无线AP（全称为Wireless Access Point，译为无线访问接入点）下会连接多个无线STA（全称为Station，译为站点）终端，AP感知到每个STA的RSSI（全称为Received Signal
Strength Indication，译为接收的信号强度指示）信号强度会因STA终端的位置及与AP的距离不同会有很大的差异。如果RSSI信号强度差异较大的多个无线STA终端同时进行传输，不管是上行还是下行传输，对AP或STA的功率控制能力要求很高，如果功率控制不准确会引入很多信号噪声，导致多用户同时传输时整体吞吐量下降，影响整个系统的传输效率。

为了更好的理解上述技术方案，下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
无线AP（Access Point）：即无线接入点，它用于无线网络的无线交换机，也是无线网络的核心。无线AP是移动计算机用户进入有线网络的接入点，主要用于宽带家庭、大楼内部以及园区内部，可以覆盖几十米至上百米。
如今WIFI(Wireless Fidelity)技术已经发展到第六代即WIFI6，也叫802.11AX技术。为了提升用户终端密集场景的用户体验，802.11AX引入了OFDMA(Orthogonal
Frequency Division Multiple Access，正交频分多址)技术。该技术将有限的带宽划分为不同大小的RU(Resource Units，资源单元)，不同的用户终端分配不同的RU单元，这样同一时间有限的带宽就可以给多个用户，提高频谱资源的利用效率，提升多用户场景系统性能。其中协议规定了可以用于资源分配的RU大小分别为：26-tone，52-tone，106-tone，242-tone，484-tone，996-tone。其中26-tone(24个Data子载波, 2个Pilot子载波)是最小的RU单元，即2MHz，996-tone是可分配的最大RU单元。虽然802.11AX协议规定了可分配的RU单元大小，但没有规定AP应该如何给多个用户终端分配RU单元，在多用户并发的场景下需要合理分配RU单元以达到最大化利用频谱资源的目的。
802.11AX协议规定的OFDMA技术可实现多个无线终端同时传输，在实际使用场景中，一个AP下会连接多个无线STA终端，AP感知到每个STA的RSSI信号强度会因STA终端的位置及与AP的距离不同会有很大的差异。如果RSSI信号强度差异很大的多个无线STA终端同时进行传输，不管是上行还是下行传输，对AP或STA的功率控制能力要求很高，如果功率控制不准确会引入很多信号噪声，导致多用户同时传输时整体吞吐量下降，影响整个系统的传输效率。
因此，当前需要解决现有在信号强度差异较大的多个无线STA终端同时进行传输时容易引入很多信号噪声，导致多用户同时传输时整体吞吐量下降，影响整个系统的传输效率的问题。鉴于此，本申请提出一种多用户无线数据传输方法、系统、设备及存储介质。

memory），例如磁盘存储器。存储器1005可选的还可以是独立于前述处理器1001的存储装置。

请参照图2，基于上述多用户无线数据传输设备硬件架构，下面提出本申请的多用户无线数据传输方法的实施例一，所述多用户无线数据传输方法包括以下步骤：
S100、获取多个无线终端设备的信号强度和数量；
基于802.11AX协议规定的OFDMA技术可实现多个无线终端设备同时传输，但是无线接入点感知到每个无线终端设备的信号强度会因无线终端设备的位置及与无线接入点的距离不同会有很大的差异。而无线终端设备之间信号强度之间的差异导致引入很多信号噪声，导致多用户同时传输时整体吞吐量下降，影响整个系统的传输效率。因此，首先应该获取多个无线终端设备的信号强度，并根据信号强度对多个无线终端设备进行初步分级，确定每一信号强度分级的无线终端设备数量，为下一步确定多个无线终端设备的分组策略提供基础。
请参照图3，具体地，步骤S100包括：S110、获取多个无线终端设备的信号强度；
具体地，可通过多用户无线数据传输设备的无线接口接收无线终端设备发送的广播包，从广播包中解析得到无线终端设备发送的无线信号的信号强度和无线终端设备的属性信息。并对无线终端设备发送的无线信号的信号强度和无线终端设备的属性信息进行记录。其中，属性信息包括无线终端设备的名称和无线终端设备所使用的无线局域网标准。
S120、根据预设的信号强度分级表，对多个无线终端设备的信号强度进行分级，统计各个信号强度分级中无线终端设备的数量。
在一些实施例中，预设的信号强度分级表可包括小于信号强度阈值下限的第一信号强度分级，以及大于或等于信号强度阈值下限的第二信号强度分级。例如，可设置信号强度阈值下限的-90dBm。当获取的无线终端设备的信号强度低于-90dBm，则把对应的无线终端设备的信号强度划分到第一信号强度分级；当获取的无线终端设备的信号强度大于或等于-90dBm，则把对应的无线终端设备的信号强度划分到第二信号强度分级。统计第一信号强度分级和第二信号强度分级中的无线终端设备的数量。应理解，这里列举的信号强度阈值下限的具体数值只是为了本领域技术人员能够更好地理解本实施例的技术方案。而不应该理解为对信号强度阈值下限的限制。
为了对无线终端设备的信号强度进行更细致的划分，在其他一些实施例中，所述预设的信号强度分级表可包括小于信号强度阈值下限的第三信号强度分级，大于信号强度阈值上限的第四信号强度分级，以及大于或等于信号强度阈值下限且小于或等于信号强度阈值上限第五信号强度分级。
例如，可设置信号强度阈值下限的-80dBm，设置信号强度阈值上限为-35dBm。当获取的无线终端设备的信号强度低于-80dBm，则把对应的无线终端设备的信号强度划分到第三信号强度分级；当获取的无线终端设备的信号强度大于-35dBm，则把对应的无线终端设备的信号强度划分到第四信号强度分级；当获取的无线终端设备的信号强度位于[-80dBm，-35dBm]这个区间之间，则把对应的无线终端设备的信号强度划分到第五信号强度分级。统计第一信号强度分级和第二信号强度分级中的无线终端设备的数量。应理解，这里列举的信号强度阈值上限、信号强度阈值下限的具体数值只是为了本领域技术人员能够更好地理解本实施例的技术方案。而不应该理解为对信号强度阈值下限的限制。
进一步地，还可以将第五信号强度分级进一步地细分，使得第五信号强度分级内的信号强度分级之间信号强度差异更小，在后续的分组中使得同组的无线终端设备之间的信号强度差异更小。举例言之，请参照表1，RSSI1对应第二信号强度分级，RSSI11对应第一信号强度分级。所述第五信号强度分级可包括多个信号强度范围相同的第六信号强度分级。例如，在第五信号强度分级[-80dBm，-35dBm]的区间内可设置[-80dBm，-75dBm]、......、（-40dBm，-35dBm]，即RSSI2-RSSI10一共9个第六信号强度分级。同样，这里列举的第六信号强度分级的具体信号分级情况只是为了本领域技术人员能够更好地理解本实施例的技术方案。而不应该理解为对第四信号强度分级的限制。
S200、在预设分组策略中查询对应当前多个无线终端设备的信号强度和数量的分组策略；
使用信号强度分级表对无线终端设备的信号强度分级之后，本实施例根据预设数量阈值判断信号强度分级相近的无线终端设备能否划分在同组，以便同时传输的每组多个无线终端设备的信号强度相近。
对于信号强度分级较少的信号强度分级表，如步骤S120中列举的包含第一信号强度分级和第二信号强度分级的信号强度分级表，以及包含第三信号强度分级、第四信号强度分级和第五信号强度分级的信号强度分级表。则将属于同一信号强度分级的无线终端设备设为同组进行无线数据传输。
本实施例根据存在较多信号强度分级的信号强度分级表进行说明。具体地，在预设分组策略中查询单个信号强度分级的无线终端设备数量与预设数量阈值的关系，或多个信号强度相近的信号强度分级的无线终端设备数量与预设数量阈值的关系，得到对应当前多个无线终端设备的信号强度分级情况的分组策略。
请参照表2，上表中的R
1-R
11与表1中的RSSI
1-RSSI
11对应相同，均表示信号强度分级，User
1-User
11表示各个信号强度分级的无线终端设备的数量。R
阈值表示信号强度阈值下限，User
阈值表示预设数量阈值。这里的R
n可以与表1中的RSSI
10对应，也可以其他的信号强度分级，即R
n表示信号强度分级的通式。
举例言之，若多个无线终端设备的信号强度都小于信号强度阈值下限，即R<R
阈值，则把多个无线终端设备分到同一个组进行无线数据传输。
若信号强度位于R
1的信号强度分级的无线终端数量若大于或等于预设数量阈值，即User
1≥User
阈值，则说明无线终端数量位于R
1的信号强度分级的无线终端数量达到预设数量阈值，应该将信号强度位于R
1的信号强度分级的无线终端数量设置同一个组，即Team
1。
若信号强度位于R
1的信号强度分级的无线终端数量若小于预设数量阈值，即User
1<User
阈值，则判断信号强度相近的信号强度分级的无线终端数量与预设数量阈值的关系。进一步地，若信号强度位于R
1的信号强度分级的无线终端数量与信号强度位于R
2的信号强度分级的无线终端数量之和大于预设数量阈值，即User
1+User
2≥User
阈值，此时说明信号强度位于R
1的信号强度分级未达到预设数量阈值，应该将信号强度位于R
1的信号强度分级和信号强度位于R
2的信号强度分级的无线终端设备设置在同一组即Team
2进行无线数据传输。同理，Team
3、Team
4、Team
5、......Team
n-1的分组原理同上。
综上，本实施例判断每一信号强度分级的无线终端设备数量与预设数量阈值的关系，若某一信号强度分级的无线终端数量大于或等于预设数量阈值，则单独组成一组进行无线数据传输，无需与其他的信号强度分级的无线终端设备分在同组进行无线数据传输。若无线终端数量小于预设数量阈值，则判断相近的信号强度分级的无线终端设备数量与预设数量阈值的关系，若相近的信号强度分级的无线终端设备数量小于预设数量阈值，且两个信号强度分级的无线终端设备之和大于或等于预设数量阈值，则将两个信号强度分级的无线终端设备合成同组进行无线数据传输。
需要说明的是，若信号强度相近的三个或三个以上信号强度分级的无线终端设备数量信号强度分级最小的无线终端设备数量（即R1）小于预设数量阈值，但多个信号强度分级的无线终端设备数量之和大于或等于预设数量阈值，可将信号强度相近的三个或三个以上信号强度分级的无线终端设备设置在同一组进行无线数据传输。值得一提的是，若User
1的无线终端设备数量小于预设数量阈值，且User
1至User
n的无线终端设备数量之和小于预设数量阈值，则将信号强度分级处于R
1-R
11的全部无线终端设备设置同组进行无线数据传输。
S300、根据所述分组策略对多个无线终端设备进行无线数据传输。
基于步骤S200得到的分组策略，对无线终端设备进行分组无线数据传输。

基于同一发明构思，请参照图4，本申请还提出实施例二，实施例二建立在实施例一的基础之上。
实施例二
本实施例的多用户无线数据传输方法包括：
S400、获取所述预设分组策略的步骤。在获取多个无线终端设备的信号强度和数量之前，应该先获取设置于多用户无线数据传输设备的存储器1005中的预设分组策略。可通过设置信号强度阈值下限、信号强度阈值上限和信号强度阈值下限与信号强度阈值上限之前的信号强度分级形成信号强度分级表，再针对每个信号强度分级的无线终端设备设置分组条件，形成预设分组策略。
分组条件为：若多个无线终端设备的信号强度都小于信号强度阈值下限，即R<R
阈值，则把多个无线终端设备分到同一个组进行无线数据传输。
若信号强度位于R
1的信号强度分级的无线终端数量若大于或等于预设数量阈值，即User
1≥User
阈值，则说明无线终端数量位于R
1的信号强度分级的无线终端数量达到预设数量阈值，应该将信号强度位于R
1的信号强度分级的无线终端数量设置同一个组，即Team
1。
若信号强度位于R
1的信号强度分级的无线终端数量若小于预设数量阈值，即User
1<User
阈值，则判断信号强度相近的信号强度分级的无线终端数量与预设数量阈值的关系。进一步地，若信号强度位于R
1的信号强度分级的无线终端数量与信号强度位于R
2的信号强度分级的无线终端数量之和大于预设数量阈值，即User
1+User
2≥User
阈值，此时说明信号强度位于R
1的信号强度分级未达到预设数量阈值，应该将信号强度位于R
1的信号强度分级和信号强度位于R
2的信号强度分级的无线终端设备设置在同一组即Team
2进行无线数据传输。同理，Team
3、Team
4、Team
5、......Team
n-1的分组原理同上。
若信号强度相近的三个或三个以上信号强度分级的无线终端设备数量信号强度分级最小的无线终端设备数量（即R1）小于预设数量阈值，但多个信号强度分级的无线终端设备数量之和大于或等于预设数量阈值，可将信号强度相近的三个或三个以上信号强度分级的无线终端设备设置在同一组进行无线数据传输。值得一提的是，若User
1的无线终端设备数量小于预设数量阈值，且User
1至User
n的无线终端设备数量之和小于预设数量阈值，则将信号强度分级处于R
1-R
11的全部无线终端设备设置同组进行无线数据传输。
