As users' needs for wireless networks upgrade, WiFi technology and standards continue to evolve and develop. Starting from WiFi 4, WiFi technology has introduced multiple antennas and multiple-input multiple-output (MIMO, Multiple-In Multiple-Out) technology. Starting from WiFi 5, multi-user-multiple-input multiple-output (MU-MIMO, Multi-User Multiple) has been introduced. -Input Multiple-Output) technology, WiFi 6 updates and upgrades MU-MIMO technology, supports more MIMO, higher rates, and optimizes multiple application scenarios. WiFi 6E and future WiFi 7 will introduce In the 6GHz frequency band, it is foreseeable that there will be equipment working in 2.4GHz, 5GHz and 6GHz simultaneously.
同时,随着科技的发展,使用WiFi技术的设备的种类越来越多,不仅手机、个人电脑(PC,Personal Computer)、平板电脑等能够通过WiFi进行通信,电视、冰箱、洗衣机等各种家用电器也能够通过WiFi来通信,还有很多物联网(IOT,Internet of Things)设备也能够使用WiFi进行通信。不同种类的设备对带宽的要求是不同的,例如,IOT设备只需要偶尔传输一些少量的数据而不需要大带宽,手机、PC等设备则可能需要大带宽;可能需要大带宽的设备也不是所有时间都需要大带宽,例如,手机在播放高清视频时需要大带宽,其他时候则不需要大带宽;还有一些设备在进行音视频通话等业务时则对实时性要求较高。At the same time, with the development of science and technology, there are more and more types of devices using WiFi technology. Not only mobile phones, personal computers (PCs), tablets, etc. can communicate through WiFi, but also various household appliances such as TVs, refrigerators, and washing machines. Electrical appliances can also communicate through WiFi, and many Internet of Things (IOT, Internet of Things) devices can also communicate using WiFi. Different types of devices have different requirements for bandwidth. For example, IOT devices only need to occasionally transmit a small amount of data and do not require large bandwidth, while mobile phones, PCs and other devices may require large bandwidth; not all devices that may require large bandwidth Large bandwidth is required all the time. For example, mobile phones require large bandwidth when playing high-definition videos, but do not need large bandwidth at other times; some devices have higher real-time requirements when making audio and video calls and other services.
但是,WiFi设备无法很好地满足用户不同设备、不同场景的无线通信需求,严重影响用户的使用体验。However, WiFi devices cannot well meet the wireless communication needs of users in different devices and scenarios, seriously affecting the user experience.

常见的WiFi设备包括无线路由器、用户驻地设备(CPE,Customer PremisesEquipment)等,无线路由器、CPE通常具有多跟天线,并且支持MIMO和MU-MIMO。在一些相关技术中,WiFi设备通常以最大MIMO能力启动,并且MIMO数量不再发生变化,WiFi设备的功耗较大;当客户端接入WiFi设备时,WiFi设备会根据当前的客户端接入情况将客户端分配到某一个MIMO组里并不再变化,容易导致不同MIMO组之间负载不均衡;WiFi设备的2.4GHz频段带宽较小、但传输距离较远,当多个IOT设备共享同一个2.4GHz频段的带宽时,虽然IOT设备要求的带宽较小,各个IOT设备的带宽需求也可能无法得到保障;当客户端进行音视频通话等实时性要求较高的业务时,可能会受到分配到同一个MIMO组的其他终端正在进行的大数据下载、高清视频播放等业务的影响而使时延要求得不到满足。由于存在以上问题,常见的WiFi设备无法很好地满足不同设备、不同场景的无线通信需求,严重影响用户的使用体验。Common WiFi equipment includes wireless routers, Customer Premises Equipment (CPE, Customer Premises Equipment), etc. Wireless routers and CPE usually have multiple antennas and support MIMO and MU-MIMO. In some related technologies, WiFi devices usually start with the maximum MIMO capability, and the number of MIMOs does not change. The power consumption of WiFi devices is large; when a client accesses a WiFi device, the WiFi device will access the WiFi device according to the current client The situation of assigning clients to a certain MIMO group does not change, which can easily lead to load imbalance between different MIMO groups; the 2.4GHz band bandwidth of WiFi devices is small, but the transmission distance is long. When multiple IOT devices share the same When the bandwidth of a 2.4GHz frequency band is used, although the bandwidth required by IOT devices is smaller, the bandwidth requirements of each IOT device may not be guaranteed; when the client conducts audio and video calls and other services with high real-time requirements, it may be allocated Due to the impact of big data downloading, high-definition video playback and other services being carried out by other terminals in the same MIMO group, the delay requirements cannot be met. Due to the above problems, common WiFi devices cannot well meet the wireless communication needs of different devices and different scenarios, seriously affecting the user experience.

在本公开实施例中,对频段的多输入多输出配置进行调整,可以是对该频段的MIMO数量进行调整,例如,增加该频段的MIMO数量,比如将该频段的MIMO数量由4×4调整为6×6,或减少该频段的MIMO数量,比如将该频段的MIMO数量由8×8调整为4×4;也可以是对该频段的MIMO组进行调整;还可以调整该频段除MIMO数量和MIMO组之外的MIMO配置。本公开实施例对此不做特殊限定。In the embodiment of the present disclosure, adjusting the multiple-input multiple-output configuration of the frequency band may be to adjust the number of MIMOs in the frequency band, for example, increasing the number of MIMOs in the frequency band, such as adjusting the number of MIMOs in the frequency band from 4×4 to 6×6, or reduce the number of MIMO in this frequency band, for example, adjust the number of MIMO in this frequency band from 8×8 to 4×4; you can also adjust the MIMO group in this frequency band; you can also adjust the number of MIMO in this frequency band and MIMO configuration outside the MIMO group. The embodiments of the present disclosure do not impose special limitations on this.

本公开实施例对于如何调整频段的多输入多输出配置不做特殊限定。在一些实施例中,WiFi设备的MIMO数量能够动态调整。相应地,为了实现对MIMO数量的调整,需要在根据已接入的客户端的连接状态信息确定频段的多输入多输出配置信息时,确定调整后该频段的MIMO数量。The embodiments of the present disclosure do not place special limitations on how to adjust the multiple-input multiple-output configuration of the frequency band. In some embodiments, the MIMO amount of a WiFi device can be dynamically adjusted. Accordingly, in order to adjust the number of MIMOs, it is necessary to determine the adjusted number of MIMOs in the frequency band when determining the multiple-input multiple-output configuration information of the frequency band based on the connection status information of the connected client.

在一些实施例中,客户端的连接状态信息表征已接入的客户端的数量,可以根据已接入的客户端的数量增加MIMO数量或较小MIMO数量。例如,当某一频段接入的客户端的数量较大时,则增加该频段的MIMO数量,以确保各个客户端的带宽、速率、吞吐量等需求都能得到满足;当某一频段接入的客户端的数量较小时,则减少该频段的MIMO数量,能够在满足客户端的带宽、速率、吞吐量等需求的基础上,节约WiFi设备的功耗。In some embodiments, the connection status information of the client represents the number of connected clients, and the MIMO number or the smaller MIMO number can be increased according to the number of connected clients. For example, when the number of clients connected to a certain frequency band is large, the number of MIMO in that frequency band is increased to ensure that the bandwidth, speed, throughput and other requirements of each client can be met; when the number of clients connected to a certain frequency band is When the number of clients is small, reducing the number of MIMO in this frequency band can save the power consumption of WiFi devices on the basis of meeting the bandwidth, speed, throughput and other needs of clients.
在一些实施例中,客户端的连接状态信息表征已接入的客户端的实时速率,在调整MIMO数量时,可以将已接入的客户端的实时速率总和与频段当前的MIMO配置能够支持的最大能力进行比较,并根据比较结果增加或减少频段的MIMO数量。In some embodiments, the connection status information of the client represents the real-time rate of the connected client. When adjusting the number of MIMO, the sum of the real-time rate of the connected client can be compared with the maximum capacity supported by the current MIMO configuration of the frequency band. Compare, and increase or decrease the number of MIMO in the frequency band based on the comparison result.
在一些实施例中,客户端的连接状态信息表征已接入的客户端的实时速率和已接入的客户端的数量,在调整MIMO数量时,结合已接入的客户端的数量和已接入的客户端的实时速率调整频段的MIMO数量。In some embodiments, the connection status information of the client represents the real-time rate of the connected client and the number of connected clients.

S211、对于任意一个频段,确定已接入的客户端的数量是否超过所述频段当前支持的用户数量上限。S211. For any frequency band, determine whether the number of connected clients exceeds the upper limit of the number of users currently supported by the frequency band.
S212、在已接入的客户端的数量超过所述频段当前支持的用户数量上限的情况下,将已接入的客户端的实时速率总和与所述频段当前支持的吞吐量上限进行比较。S212. When the number of connected clients exceeds the upper limit of the number of users currently supported by the frequency band, compare the sum of the real-time rates of the connected clients with the upper limit of throughput currently supported by the frequency band.
S213、在所述实时速率总和与所述吞吐量上限的比值大于预设阈值的情况下,增加所述频段的多输入多输出数量。S213. If the ratio of the total real-time rate to the throughput upper limit is greater than a preset threshold, increase the number of multiple input multiple outputs in the frequency band.
在本公开实施例中,配置的MIMO数量不同,能够支持的客户端的数量也不同。频段当前支持的用户数量上限,是指在当前配置的频段的MIMO数量下,能够支持的客户端的最大数量。例如,当前配置的频段的MIMO数量为4×4时,最多能够支持2个2×2的客户端、或4个1×1的客户端、或2个1×1的客户端和1个2×2的客户端。In this embodiment of the present disclosure, the number of configured MIMOs is different, and the number of clients that can be supported is also different. The upper limit of the number of users currently supported by the frequency band refers to the maximum number of clients that can be supported under the currently configured MIMO number of the frequency band. For example, when the MIMO number of the currently configured frequency band is 4×4, it can support up to two 2×2 clients, or four 1×1 clients, or two 1×1 clients and one 2×1 client. ×2 clients.
本公开实施例对预设阈值不做特殊限定。在一些实施例中,预设阈值的取值范围为50%至70%。例如,预设阈值为60%,即,当同一频段接入的客户端的实时速率总和大于该频段当前配置的MIMO数量的最大吞吐量的60%时,则增加该频段的MIMO数量。The embodiment of the present disclosure does not place special limitations on the preset threshold. In some embodiments, the preset threshold ranges from 50% to 70%. For example, the preset threshold is 60%, that is, when the sum of the real-time rates of clients accessing the same frequency band is greater than 60% of the maximum throughput of the currently configured number of MIMOs in the frequency band, the number of MIMOs in the frequency band is increased.
本公开实施例对于如何增加MIMO数量不做特殊限定。在一些实施例中,将MIMO数量划分为多个级别,例如,划分为2×2、4×4、6×6、8×8等多个级别,当需要增加频段的MIMO数量时,则将该频段配置的MIMO数量提升一个级别,比如由4×4提升到6×6;每提升一个级别,则通过步骤S211至S213,将该频段接入的客户端的实时速率总和与提升后的级别支持的吞吐量上限进行比较,直至达到最高级别或实时速率总和与吞吐量上限的比值小于或等于预设阈值。The embodiments of this disclosure do not place special limitations on how to increase the number of MIMOs. In some embodiments, the number of MIMO is divided into multiple levels, for example, into multiple levels such as 2×2, 4×4, 6×6, 8×8, etc. When it is necessary to increase the number of MIMO in a frequency band, The number of MIMO configured in the frequency band is increased by one level, for example, from 4×4 to 6×6. Each time the level is increased, through steps S211 to S213, the sum of the real-time rates of the clients connected to the frequency band and the upgraded level support are The throughput upper limit is compared until the highest level is reached or the ratio of the total real-time rate to the throughput upper limit is less than or equal to the preset threshold.
在一些实施例中,对于任意一个频段,在已接入的客户端的数量未超过所述频段当前支持的用户数量上限的情况下、或在实时速率总和与吞吐量上限的比值不大于预设阈值的情况下,则不调整频段的MIMO数量。In some embodiments, for any frequency band, when the number of connected clients does not exceed the upper limit of the number of users currently supported by the frequency band, or when the ratio of the total real-time rate to the throughput upper limit is not greater than a preset threshold In the case of , the MIMO quantity of the frequency band will not be adjusted.
在本公开实施例中,结合已接入的客户端的数量和已接入的客户端的实时速率调整频段的MIMO数量,能够兼顾频段支持的用户数量能力和吞吐量能力,在保证各个客户端的速率要求的基础上,提高MIMO的使用效率。In this disclosed embodiment, combining the number of connected clients and the real-time rate adjustment of the MIMO number of the connected clients, it is possible to take into account the number of users and throughput capabilities supported by the frequency band, while ensuring the rate requirements of each client. On the basis of improving MIMO usage efficiency.
在一些实施例中,参照图3,根据接入的所述客户端的连接状态信息,确定各个频段的多输入多输出数量,包括:In some embodiments, referring to Figure 3, the multiple-input multiple-output number of each frequency band is determined based on the connection status information of the accessed client, including:
S214、对于任意一个频段,在已接入的客户端的实时速率总和与所述频段当前支持的吞吐量上限的比值小于预设阈值、且持续预设时长的情况下,减少所述频段的多输入多输出数量。S214. For any frequency band, if the ratio of the total real-time rate of the connected clients to the throughput upper limit currently supported by the frequency band is less than the preset threshold and continues for a preset time, reduce the multiple inputs of the frequency band. Multiple output quantities.
在本公开实施例中,可以针对WiFi设备支持的各个频段,在满足步骤S214的条件的情况下,减少MIMO数量;对于新的频段,例如WiFi 6E以及未来的WiFi 7设备将引入的6GHz频段,接入的客户端可能较少,也可以通过步骤S214有针对的减少新的频段的MIMO数量。In the embodiment of the present disclosure, the number of MIMO can be reduced for each frequency band supported by WiFi devices when the conditions of step S214 are met; for new frequency bands, such as WiFi 6E and the 6GHz frequency band that will be introduced by future WiFi 7 devices, There may be fewer clients connected, and the number of MIMO in the new frequency band may also be reduced in a targeted manner through step S214.
举例说明,在一些场景中,CPE或者无线路由器支持2.4GHz、5GHz、6GHz三频并发,但是支持6GHz的站点(station)还没有出现或相对较少,则可以使CPE或者无线路由器6GHz频段工作在低MIMO配置下。在大多数家庭使用场景下,当家里无人时,家里的无线路由器或者CPE会没有客户端接入或接入的客户端较少,也可以让CPE或无线路由器工作在低MIMO配置下。For example, in some scenarios, the CPE or wireless router supports three-band concurrency of 2.4GHz, 5GHz, and 6GHz, but stations that support 6GHz have not yet appeared or are relatively few, so the CPE or wireless router can be made to work in the 6GHz frequency band. Under low MIMO configuration. In most home usage scenarios, when there is no one at home, the wireless router or CPE at home will have no or fewer clients accessing the home. The CPE or wireless router can also be made to work in a low MIMO configuration.
本公开实施例对于如何增加MIMO数量不做特殊限定。在一些实施例中,将MIMO数量划分为多个级别,例如,划分为2×2、4×4、6×6、8×8等多个级别,当需要减少频段的MIMO数量时,则将该频段配置的MIMO数量降低一个级别,比如由6×6降为4×4。The embodiments of this disclosure do not place special limitations on how to increase the number of MIMOs. In some embodiments, the number of MIMO is divided into multiple levels, for example, into multiple levels such as 2×2, 4×4, 6×6, 8×8, etc. When it is necessary to reduce the number of MIMO in a frequency band, The number of MIMO configured in this frequency band is reduced by one level, for example, from 6×6 to 4×4.
在一些实施例中,WiFi设备的MIMO组能够动态调整。相应地,为了实现对MIMO组的调整,需要在根据已接入的客户端的连接状态信息确定频段的多输入多输出配置信息时,为接入的客户端重新分配MIMO组。In some embodiments, the MIMO group of WiFi devices can be dynamically adjusted. Accordingly, in order to adjust the MIMO group, the MIMO group needs to be reassigned to the accessed client when the multiple-input multiple-output configuration information of the frequency band is determined based on the connection status information of the accessed client.
相应地,在一些实施例中,参照图2,根据已接入的客户端的连接状态信息,确定各个频段的多输入多输出配置信息,包括:Accordingly, in some embodiments, referring to Figure 2, the multiple-input multiple-output configuration information of each frequency band is determined based on the connection status information of the accessed client, including:
S22、根据已接入的客户端的连接状态信息,将客户端分配到至少一个多输入多输出组。S22. According to the connection status information of the connected client, allocate the client to at least one multiple-input multiple-output group.
本公开实施例对于如何重新分配MIMO组不做特殊限定。The embodiment of the present disclosure does not place special limitations on how to reallocate MIMO groups.
在一些实施例中,对于任意一个频段,根据客户端与WiFi设备之间距离的远近,将距离WiFi设备较远的客户端和距离WiFi设备较近的客户端分配到不同的MIMO组。In some embodiments, for any frequency band, clients farther from the WiFi device and clients closer to the WiFi device are assigned to different MIMO groups based on the distance between the client and the WiFi device.
相应地,在一些实施例中,参照图4,根据已接入的客户端的连接状态信息,将客户端分配到至少一个多输入多输出组,包括:Accordingly, in some embodiments, referring to Figure 4, the client is assigned to at least one multiple-input multiple-output group according to the connection status information of the accessed client, including:
S221、对于任意一个频段,根据已接入的客户端的连接状态信息,将已接入的客户端划分为远距离客户端和近距离客户端。S221. For any frequency band, divide the connected clients into long-distance clients and short-distance clients according to the connection status information of the connected clients.
S222、将所述远距离客户端和所述近距离客户端分配到不同的多输入多输出组。S222. Assign the long-distance client and the short-distance client to different multiple-input multiple-output groups.
本公开实施例对于如何将已接入的客户端划分为远距离客户端和近距离客户端不做特殊限定。在一些实施例中,连接状态信息可以表征客户端的位置信息,根据客户端的位置信息将已接入的客户端划分为远距离客户端和近距离客户端。在一些实施例中,连接状态信息可以表征客户端的接收信号强度指示(RSSI,Received Signal StrengthIndication)信息,客户端的RSSI信息能够反映客户端与WiFi设备的距离关系,故而可以根据客户端的RSSI信息将接入的客户端划分为远距离客户端和近距离客户端。The embodiment of this disclosure does not place any special restrictions on how to divide the connected clients into long-distance clients and short-distance clients. In some embodiments, the connection status information may represent the location information of the client, and the connected clients are divided into long-distance clients and short-distance clients based on the location information of the clients. In some embodiments, the connection status information can represent the Received Signal Strength Indication (RSSI) information of the client. The RSSI information of the client can reflect the distance relationship between the client and the WiFi device. Therefore, the connection status can be determined based on the RSSI information of the client. Incoming clients are divided into long-distance clients and short-distance clients.
需要说明的是,在本公开实施例中,远距离客户端和近距离客户端的带宽需求可能不同,例如,在2.4GHz频段,远距离客户端要求的带宽较小,近距离客户端要求的带宽较大,将远距离客户端和近距离客户端分配到不同的MIMO组,可以避免远距离客户端和近距离客户端相互影响,从而使各个客户端的带宽需求都能得到保障。It should be noted that in the embodiments of the present disclosure, the bandwidth requirements of long-distance clients and short-distance clients may be different. For example, in the 2.4GHz frequency band, the bandwidth required by long-distance clients is smaller, and the bandwidth required by short-distance clients is smaller. Larger, allocating long-distance clients and short-distance clients to different MIMO groups can avoid the mutual influence of long-distance clients and short-distance clients, so that the bandwidth requirements of each client can be guaranteed.
举例说明,当前智能家居设备越来越多,家庭中可能会有较多智能家居设备连接到无线路由器或者CPE上,该场景下,很多智能家居设备可能仅支持2.4GHz频段,而且会放在家里的不同位置,并会距离路由器或者CPE较远,若将2.4GHz的MIMO配置高一些,并将这些智能家居设备分配到不同的MIMO组上,能够保证这些智能家居设备的正常通信。For example, there are currently more and more smart home devices, and there may be more smart home devices connected to wireless routers or CPEs in the home. In this scenario, many smart home devices may only support the 2.4GHz frequency band and will be placed at home. Different locations, and will be far away from the router or CPE. If the 2.4GHz MIMO configuration is higher and these smart home devices are assigned to different MIMO groups, normal communication of these smart home devices can be ensured.
在本公开实施例中,在将远距离客户端和近距离客户端分配到不同的MIMO组时,远距离客户端可以分配到一个或多个MIMO组,近距离客户端也可以分配到一个或多个MIMO组。本公开实施例对此不做特殊限定。In the embodiment of the present disclosure, when the long-distance client and the short-distance client are assigned to different MIMO groups, the long-distance client can be assigned to one or more MIMO groups, and the short-distance client can also be assigned to one or more MIMO groups. Multiple MIMO groups. The embodiments of the present disclosure do not impose special limitations on this.
在一些实施例中,对于任意一个频段,可以根据远距离客户端和近距离客户端的数量,调整远距离客户端的MIMO组和近距离客户端的MIMO组的数量。例如,若远距离客户端的数量较多,则增加远距离客户端的MIMO组的数量;若近距离客户端的数量较多,则增加近距离客户端的MIMO数量。In some embodiments, for any frequency band, the number of MIMO groups of long-distance clients and the number of MIMO groups of short-distance clients can be adjusted according to the number of long-distance clients and short-distance clients. For example, if there are a large number of long-distance clients, increase the number of MIMO groups of long-distance clients; if there are a large number of short-distance clients, increase the number of MIMO groups of short-distance clients.
相应地,在一些实施例中,将所述远距离客户端和所述近距离客户端分配到不同的多输入多输出组,包括:根据所述远距离客户端的数量和所述近距离客户端的数量,确定第一多输入多输出组的数量和第二多输入多输出组的数量;将所述远距离客户端分配到所述第一多输入多输出组;将所述近距离客户端分配到所述第二多输入多输出组。Accordingly, in some embodiments, the long-distance clients and the short-distance clients are assigned to different multiple-input multiple-output groups, including: according to the number of the long-distance clients and the number of the short-distance clients. quantity, determine the number of the first multiple-input multiple-output group and the number of the second multiple-input multiple-output group; assign the long-distance client to the first multiple-input multiple-output group; assign the close-range client to the second MIMO group.
需要说明的是,第一MIMO组就是指远距离客户端的MIMO组,第二MIMO组就是指近距离客户的MIMO组。It should be noted that the first MIMO group refers to the MIMO group of long-distance clients, and the second MIMO group refers to the MIMO group of short-distance clients.
在一些实施例中,根据已接入的客户端的连接状态信息,将已接入的客户端划分为远距离客户端和近距离客户端,包括:对于任意一个客户端,在所述客户端的接收信号强度指示信息小于或等于强度阈值的情况下,将所述客户端划分为远距离客户端;在所述客户端的接收信号强度指示信息大于所述强度阈值的情况下,将所述客户端划分为近距离客户端。In some embodiments, according to the connection status information of the connected client, the connected client is divided into a long-distance client and a short-distance client, including: for any client, the reception of the client If the signal strength indication information is less than or equal to the strength threshold, the client is classified as a long-distance client; if the received signal strength indication information of the client is greater than the strength threshold, the client is classified as a long-distance client. For close-range clients.
举例说明,对于2.4GHz频段,设置强度阈值为-75DBm,当客户端的RSSI信息小于或等于-75DBm,认为客户端是远离WiFi设备的,则将该客户端划分为远距离设备;当客户端的RSSI信息大于-75DBm,认为客户端是靠近WiFi设备的,则将该客户端划分为近距离设备。For example, for the 2.4GHz frequency band, set the intensity threshold to -75DBm. When the client's RSSI information is less than or equal to -75DBm, the client is considered to be far away from the WiFi device, and the client is classified as a long-distance device; when the client's RSSI If the information is greater than -75DBm, it is considered that the client is close to the WiFi device, and the client is classified as a short-distance device.
在一些实施例中,对于任意一个频段,根据客户端的服务质量优先级调整客户端的MIMO组。In some embodiments, for any frequency band, the client's MIMO group is adjusted according to the client's service quality priority.

S224、根据客户端的服务质量优先级将客户端分配到不同的多输入多输出组。S224. Assign the client to different multiple-input multiple-output groups according to the client's service quality priority.
本公开实施例对于如何根据客户端的服务质量(QoS,Quality of Service)优先级将客户端分配到不同的MIMO组不做特殊限定。例如,使QoS优先级高的客户端独占一个MIMO组,从而能够确保该客户端的服务质量,比如客户端正在进行音视频通话等实时性要求高的业务,将该客户端独占分配到一个MIMO组,可以避免其他客户端正在进行的大数据下载、高清视频播放等业务的影响。例如,当有多个QoS优先级高的客户端时,将多个QoS优先级高的客户端分散到不同的MIMO组中,比如将多个正在进行音视频通话等实时性要求高的业务的客户端平均分配到多个较空闲的MIMO组,可以避免多个客户端的业务排队造成的时延增加。故而,在本公开实施例中,根据客户端的QoS优先级将客户端分配到不同的MIMO组,在不同场景中都能够使客户端的服务质量得到保障。The embodiments of this disclosure do not place special limitations on how to allocate clients to different MIMO groups according to their Quality of Service (QoS) priorities. For example, a client with high QoS priority can be exclusively assigned to a MIMO group to ensure the quality of service of the client. For example, if the client is conducting services with high real-time requirements such as audio and video calls, the client can be exclusively assigned to a MIMO group. , which can avoid the impact of other clients' ongoing big data downloading, high-definition video playback and other services. For example, when there are multiple clients with high QoS priorities, disperse the multiple clients with high QoS priorities into different MIMO groups, such as multiple clients that are conducting audio and video calls and other services with high real-time requirements. Clients are evenly allocated to multiple relatively idle MIMO groups, which can avoid the increase in delay caused by multiple clients' service queuing. Therefore, in the embodiment of the present disclosure, clients are assigned to different MIMO groups according to their QoS priorities, so that the service quality of the clients can be guaranteed in different scenarios.
相应地,在一些实施例中,根据客户端的服务质量优先级将客户端分配到不同的多输入多输出组,包括:确定所述频段的各个多输入多输出组中的至少一个空闲多输入多输出组;将服务质量优先级高的客户端分配到所述空闲多输入多输出组。Accordingly, in some embodiments, allocating the client to different multiple-input multiple-output groups according to the client's quality of service priority includes: determining at least one idle multiple-input multiple-output group in each multiple-input multiple-output group of the frequency band.

实施例二Embodiment 2
本实施例基于实施例一的WiFi设备。This embodiment is based on the WiFi device of Embodiment 1.
多输入多输出的控制过程包括:The control process of multiple inputs and multiple outputs includes:
1、信息采集模块对客户端的连接状态信息进行采集。需要采集的信息包括:1)每一个频段接入的客户端的数量;2)接入的每一个客户端的流的个数、该客户端支持的带宽,从而确定该客户端支持的MIMO的信息、该客户端能够支持的最大物理层速率;3)接入的客户端的实时速率情况,动态统计实时速率情况包括:每秒采集一次发往某个客户端的数据发送量,保存n组数据,例如5秒或者10秒内的数据,每个客户端都保留最近的n组数据,每秒钟计算一次该客户端最近n秒的平均速率;4)统计各个接入的客户端的RSSI信息,每个客户端无论处于何种状态,只要处于连接状态,都会向它连接的WiFi设备发送数据,从这些数据中能够获取到报文的RSSI,从而判断该客户端与WiFi设备的大致距离,动态统计RSSI信息包括:记录该客户端的一段时间内的RSSI情况,保存最近的m次数据,然后每秒计算一次RSSI的平均值;5)所有接入客户端的业务情况,本实施例主要是按照QoS优先级顺序来统计发往各个客户端的数据量。1. The information collection module collects the connection status information of the client. The information that needs to be collected includes: 1) the number of clients connected to each frequency band; 2) the number of streams of each client connected, and the bandwidth supported by the client, so as to determine the MIMO information supported by the client, The maximum physical layer rate that the client can support; 3) The real-time rate of the connected client. Dynamic statistics of the real-time rate include: collecting the amount of data sent to a client once per second, and saving n groups of data, such as 5 For data within seconds or 10 seconds, each client retains the latest n sets of data, and calculates the average rate of the client in the last n seconds every second; 4) Statistics of the RSSI information of each accessed client, each client No matter what state the client is in, as long as it is connected, it will send data to the WiFi device it is connected to. From these data, the RSSI of the message can be obtained, thereby determining the approximate distance between the client and the WiFi device and dynamically counting RSSI information. Including: recording the RSSI situation of the client within a period of time, saving the latest m data, and then calculating the average RSSI every second; 5) The business situation of all access clients, this embodiment mainly follows the QoS priority order To count the amount of data sent to each client.
2、对采集到的数据进行分析和处理。包括五种场景:2. Analyze and process the collected data. Includes five scenarios:
第一种场景,当接入到某个频段的客户端数量少于等于WiFi设备当前MIMO配置能够支持的MU-MIMO用户数量时,则保持当前配置;例如,当前WiFi设备配置为4x4 MIMO时,接入用户数为2个2x2的客户端,或者1个2x2的客户端,或者2个1x1客户端加1个2x2客户端等情况,也就时接入的客户端的MIMO数量小于或等于WiFi设备能够支持的MU-MIMO的用户数,则保持WiFi设备的当前配置不变。In the first scenario, when the number of clients accessing a certain frequency band is less than or equal to the number of MU-MIMO users that the current MIMO configuration of the WiFi device can support, the current configuration is maintained; for example, when the current WiFi device is configured as 4x4 MIMO, When the number of accessed users is two 2x2 clients, or one 2x2 client, or two 1x1 clients plus one 2x2 client, etc., that is, the number of MIMO connected clients is less than or equal to the WiFi device. The number of MU-MIMO users that can be supported remains unchanged with the current configuration of the WiFi device.
第二种场景,当接入到某个频段的客户端数量超过WiFi设备当前MIMO配置能够支持的MU-MIMO用户数量时,计算接入到同一个频段的客户端的实时速率总和,如果该频段所有客户端的实时速率总和小于WiFi设备当前MIMO配置能够支持的最大吞吐量的60%,则保持WiFi备的当前配置不变;否则,如果当前WiFi设备的MIMO配置未达到WiFi设备能够支持的最大能力,则将WiFi设备的MIMO配置提升一个级别,如从4x4提升到6x6。In the second scenario, when the number of clients connected to a certain frequency band exceeds the number of MU-MIMO users that the current MIMO configuration of the WiFi device can support, the sum of the real-time rates of the clients connected to the same frequency band is calculated. If all the clients in the frequency band If the total real-time rate of the client is less than 60% of the maximum throughput that the current MIMO configuration of the WiFi device can support, the current configuration of the WiFi device remains unchanged; otherwise, if the MIMO configuration of the current WiFi device does not reach the maximum capacity that the WiFi device can support, Then increase the MIMO configuration of the WiFi device to one level, such as from 4x4 to 6x6.
第三种场景,针对2.4G,设置一个RSSI的阈值,例如-75DBm,当某个客户端的平均RSSI小于或等于该阈值时,表示该客户端是远离WiFi设备的,而RSSI大于该阈值的客户端,认为该客户端是距离WiFi设备较近的,按照该阈值将接入的客户端分配到不同的MIMO组上,如果远距离的客户端较多,并且2.4GHz频段有多余的MIMO可用,则将远距离的客户端按照数量和RSSI情况再次进行分配到不同的MIMO组上。The third scenario, for 2.4G, sets an RSSI threshold, such as -75DBm. When the average RSSI of a client is less than or equal to the threshold, it means that the client is far away from the WiFi device, and clients whose RSSI is greater than the threshold end, it is considered that the client is close to the WiFi device, and the accessed clients are assigned to different MIMO groups according to this threshold. If there are many long-distance clients and there is excess MIMO available in the 2.4GHz band, Then the remote clients will be allocated to different MIMO groups again according to the number and RSSI conditions.
第四种场景,根据信息采集模块中采集到的各个客户端的数据包的QoS信息,以及各个客户端的速率情况,当出现某个或者某些客户端的数据中,优先级高的报文占的比例超过其总数的30%的时候,标识该客户端可能是在进行一些实时行要求高的业务,如视频播放、视频通话、语音通话等,则要按照每个MIMO组里的客户端的速率情况来确认每个MIMO组的空闲程度,然后将正在进行实时性要求高的客户端分配到较为空闲的MIMO组上。In the fourth scenario, based on the QoS information of each client's data packets collected in the information collection module and the rate of each client, when there is a certain or certain client's data, the proportion of high-priority packets When it exceeds 30% of the total number, it indicates that the client may be performing some services with high real-time requirements, such as video playback, video calls, voice calls, etc., and the rate should be determined according to the rate of the clients in each MIMO group. Confirm the idleness of each MIMO group, and then allocate clients with high real-time requirements to relatively idle MIMO groups.
第五种场景,当接入到本设备某个频段的客户端数量减少,而客户端的总MIMO数和总速率小于WiFi设备当前MIMO配置的下一级配置能够提供的最大能力的60%时候,并且维持了很长一段时间的时候,则需要将WiFi设备该频段的MIMO配置降低一个级别。In the fifth scenario, when the number of clients connected to a certain frequency band of the device decreases, and the total MIMO number and total rate of the clients are less than 60% of the maximum capability provided by the next-level configuration of the current MIMO configuration of the WiFi device, And if it is maintained for a long period of time, the MIMO configuration of the WiFi device in this frequency band needs to be lowered by one level.
3、调用芯片底层的接口,完成MIMO配置的调整,包括:调整MIMO数量和/或调整MIMO组。3. Call the interface at the bottom of the chip to complete the adjustment of the MIMO configuration, including: adjusting the number of MIMOs and/or adjusting the MIMO groups.
