Description

一种微波通信的方法及装置Method and device for microwave communication 技术领域Technical field
本申请涉及通信技术领域，例如涉及一种微波通信的方法及装置。The present application relates to the field of communication technologies, for example, to a method and apparatus for microwave communication.
背景技术Background technique
微波通信作为一种通信手段现在被广泛应用，由于业务及带宽的迅速增加，频点资源显得越来越紧俏，应用交叉极化干扰抵消(XPIC)和多输入多输出(Multiple-Input Multiple-Output，MIMO)的极化干扰抵消技术可以应用一个频点对极化方向不同的四路业务同时传输避免相互干扰，提高频点使用效率的同时增加信道容量。As a means of communication, microwave communication is now widely used. Due to the rapid increase of services and bandwidth, frequency resources are becoming more and more tight. Cross-polarization interference cancellation (XPIC) and multiple-input multiple-output (Multiple-Input Multiple-Output) are applied. The MIMO) polarization interference cancellation technique can apply a frequency point to simultaneously transmit four channels of different polarization directions to avoid mutual interference, improve the efficiency of frequency point utilization, and increase channel capacity.
XPIC是配合CCDP使用的一种技术。CCDP利用两路正交的极化波传输信号实现传输容量加倍，而XPIC则用来消除两路极化波间的交叉干扰。理想情况下，CCDP的2个同频微波信号是正交信号，二者之间不会发生干扰，但在实际工程条件下，无论两个信号的正交性如何，总是要受天线XPD和信道传输劣化的影响，无法避免的会存在信号之间的干扰。为了抵消这些干扰，就需要使用XPIC技术。XPIC技术的基本原理是从水平和垂直两个极化方向上接收信号，并将二者进行一定处理从而从被干扰的信号中恢复出原始信号。XPIC is a technology used in conjunction with CCDP. CCDP uses two orthogonal polarized waves to transmit signals to double the transmission capacity, while XPIC eliminates cross-talk between two polarized waves. Ideally, the two co-frequency microwave signals of CCDP are orthogonal signals, and there is no interference between them. However, under actual engineering conditions, regardless of the orthogonality of the two signals, they are always subject to the antenna XPD and The effect of channel transmission degradation, unavoidable interference between signals. To counteract these interferences, you need to use XPIC technology. The basic principle of the XPIC technology is to receive signals from both the horizontal and vertical polarization directions and to process the two to recover the original signal from the interfered signals.
图1为CCDP和XPIC的原理示意图，水平调制解调器(Modem Horizontal)和垂直调制解调器(Modem Vertical)分别发送两路标识为实线和虚线的两路业务，两路业务通过CCDP采用正交的两路信号传输，对端接收到掺杂干扰的两路信号后通过过滤分离出干扰信号后与另一路信号抵消后恢复出原始的两路业务。Figure 1 is a schematic diagram of the principle of CCDP and XPIC. The horizontal modem (Modem Horizontal) and the vertical modem (Modem Vertical) respectively send two channels of service labeled as solid line and dashed line. The two channels use orthogonal two signals through CCDP. After the transmission, the opposite end receives the two signals of the doping interference, and then separates the interference signal by filtering and then cancels the original two-way service after canceling with the other signal.

It can make full use of space resources and achieve multiple transmission and reception through multiple antennas without increasing spectrum resources and antenna transmission power. In this case, the system channel capacity can be doubled. MIMO technology can be roughly divided into two categories: spatial diversity and spatial multiplexing. This system uses spatial diversity.
图2为MIMO的原理示意图，发射端通过空时映射将要发送的信号映射到多根天线上发送出去，接收端将各根天线接收到的信号进行空时译码从而恢复出发射端发送的信号。2 is a schematic diagram of the principle of MIMO. The transmitting end maps the signal to be transmitted to multiple antennas through space-time mapping, and the receiving end performs space-time decoding on the signals received by each antenna to recover the signal transmitted by the transmitting end. .
MIMO+XPIC组网中，每一空口信道都接收来自对端四个极化信号的分量，在应用MIMO+XPIC的方法进行传输时，如果一路(或者两路或者三路)业务单元出现故障或因天气原因接收信号变差导致接收异常并且无法向另三路业务单元提供抵消信号的情况下会导致四路业务单元都不可用的情况。In a MIMO+XPIC network, each air interface channel receives components from the four polarized signals at the opposite end. If a MIMO+XPIC method is used for transmission, if one (or two or three) service units fail or If the receiving signal is degraded due to weather, the reception is abnormal and the cancellation signal cannot be provided to the other three service units, which may result in the four-way service unit being unavailable.

也就是说，本公开通过使多发多收微波传输设备的设备内组成XPIC组，设备间组成MIMO组，在干扰或衰减引发业务传输中断时，按预设时间周期对故障业务单元进行主动恢复，即，本公开能在一路或几路业务单元出现故障的情况下，进行故障业务单元的主动恢复，以在故障恢复正常传输能力后恢复故障业务，从而避免相关技术中某一路或多路业务单元出现故障而导致其他路业务不可用的问题。That is to say, the present disclosure forms an XPIC group in a device of a multi-receiving and multi-receiving microwave transmission device, and the devices form a MIMO group. When the interference or attenuation causes a service transmission interruption, the faulty service unit is actively restored according to a preset time period. That is, the present disclosure can perform active recovery of the faulty service unit in the event of a failure of one or several service units, so as to recover the faulty service after the fault recovers the normal transmission capability, thereby avoiding one or more service units in the related art. A problem that caused a failure to cause other road services to be unavailable.
图4是本公开的MIMO+XPIC技术的实际应用场景示意图，如图4所示，本公开使用两个2T2R(即两发两收)微波传输设备，设备内组成XPIC组，设 备间组成MIMO组，构成MIMO+XPIC组网。每面天线为双极化天线，用合路器连接两台集光纤配线单元(Oracle Database Unloader，ODU)也可以连接一台全室外的全室外单元(All Outdoor Unit，AOU)设备，可以手动调节交叉极化隔离度(Cross Polarization Isolation)XPI值保证XPIC组链路正常工作。同一端的两面天线通过理论计算公式得出一个最佳的距离组成MIMO组，可以调节天线的距离调整一个合适的ETA值保证MIMO组链路正常工作。4 is a schematic diagram of a practical application scenario of the MIMO+XPIC technology of the present disclosure. As shown in FIG. 4, the present disclosure uses two 2T2R (ie, two-shot and two-receive) microwave transmission devices, and the device constitutes an XPIC group. The standby devices form a MIMO group to form a MIMO+XPIC network. Each antenna is a dual-polarized antenna. The combiner connects two optical fiber distribution units (Oracle Database Unloader, ODU) and can also be connected to an all-outdoor All Outdoor Unit (AOU) device. Adjusting the Cross Polarization Isolation XPI value ensures that the XPIC group link is working properly. The two-sided antenna at the same end obtains an optimal distance to form a MIMO group by theoretical calculation formula, and can adjust the distance of the antenna to adjust an appropriate ETA value to ensure the normal operation of the MIMO group link.
MIMO+XPIC组网中，每一空口信道都接收来自对端四个极化信号的分量，在应用MIMO+XPIC的方法进行传输时，如发现如果一路(或者两路或者三路)业务的单板出现故障或因天气原因接收信号变差，而导致接收异常并且无法向另三路提供抵消信号的情况下，会导致四路业务都不可用的情况。In the MIMO+XPIC network, each air interface channel receives the components of the four polarized signals from the opposite end. When transmitting the MIMO+XPIC method, if it finds a single (or two or three) service If the board fails or the received signal deteriorates due to weather, and the reception is abnormal and the offset signal cannot be provided to the other three channels, the four-way service may be unavailable.
本公开通过将极化方向不同的四路业务，配置成四个逻辑传输单元，每个传输单元对应一路业务。四个极化方向分别叫做主用极化方向业务单元Primary、次用极化方向业务单元Secondary、空间主用极化方向业务单元Spatial Primary以及空间次用极化方向业务单元Spatial Secondary，基于硬件及物理实现，主用极化方向业务单元和次用极化方向业务单元，以及空间主用极化方向业务单元和空间次用极化方向业务单元为XPIC信号干扰抵消，主用极化方向业务单元和空间主用极化方向业务单元。以及次用极化方向业务单元和空间次用极化方向业务单元为MIMO信号干扰抵消，它们之间互相包含而又互相独立，图5为MIMO+XPIC组网空口一跳的干扰信号的传输示意图。假设主用极化方向业务单元检测到当前业务发生故障时，主用极化方向业务单元会自动关闭业务发送单元，防止其干扰次用极化方向业务单元方向和空间主用极化方向业务单元方向的正常工作，同时次用极化方向业务单元方向的XPIC抵消功能和空间主用极化方向业务单元方向的MIMO抵消功能关闭，主用极化方向业务单元关闭业务发送单元后，会按照特定算法生成的时间序列打开业务发送单元尝试恢复，如果业务恢复成功流程终止，如果恢复失败关闭发送单元等待下一时间点继续尝试恢复直至业务恢复成功。 The present disclosure configures four logical transmission units by using four logical services with different polarization directions, and each transmission unit corresponds to one service. The four polarization directions are respectively called the primary polarization direction service unit Primary, the secondary polarization direction service unit Secondary, the spatial primary polarization direction service unit Spatial Primary, and the spatial secondary polarization direction service unit Spatial Secondary, based on hardware and Physical implementation, the primary polarization direction service unit and the secondary polarization direction service unit, and the spatial primary polarization direction service unit and the spatial secondary polarization direction service unit are XPIC signal interference cancellation, and the primary polarization direction service unit And the space primary polarization direction business unit. And the secondary polarization direction service unit and the spatial secondary polarization direction service unit are MIMO signal interference cancellation, which are mutually contained and independent of each other. FIG. 5 is a schematic diagram of transmission of interference signals of one hop of the MIMO+XPIC network air interface. . Assume that the primary polarization direction service unit detects that the current service is faulty, the primary polarization direction service unit automatically shuts down the service transmission unit to prevent interference with the secondary polarization direction service unit direction and the space primary polarization direction service unit. Normal operation of the direction, while the XPIC cancellation function in the direction of the service unit of the secondary polarization direction and the MIMO cancellation function in the direction of the service unit of the spatial primary polarization direction are closed, and the service unit of the primary polarization direction closes the service transmission unit, and then according to the specific The time series generated by the algorithm opens the service sending unit to try to recover. If the service recovery success process is terminated, if the recovery fails, the sending unit waits for the next time point to continue to try to recover until the service recovery is successful.
设置完后，各个业务单元具有以下属性：Once set up, each business unit has the following properties:

实施时，当所述故障业务单元为一个时，所述按预设时间周期对故障业务单元进行主动恢复，可以包括：In the implementation, when the faulty service unit is one, the active recovery of the faulty service unit according to the preset time period may include:
关闭所述故障业务单元，并关闭所述故障业务单元的XPIC抵消功能业务单元和MIMO抵消功能业务单元；Shutting down the faulty service unit, and turning off the XPIC cancellation function service unit and the MIMO cancellation function service unit of the faulty service unit;
按照时间序列生成算法产生的预设时间周期，打开故障业务发送单元进行定时恢复，直至业务恢复成功。According to the preset time period generated by the time series generation algorithm, the faulty service sending unit is opened for timing recovery until the service recovery is successful.
本公开所述关闭故障业务单元，可以包括：当所述故障业务单元的业务持续失锁第一预定时间后，关闭所述故障业务单元；The closing the faulty service unit in the disclosure may include: closing the faulty service unit after the service of the faulty service unit continues to lose lock for a first predetermined time;
实施时，本公开是在故障业务单元的业务持续失锁2秒后，关闭所述故障业务单元。In implementation, the present disclosure shuts down the faulty service unit after the faulty service unit's service continues to lose lock for 2 seconds.
所述按照时间序列生成算法产生的预设时间周期，打开故障业务发送单元进行定时恢复，可以包括：The step of generating the faulty service sending unit to perform the timing recovery according to the preset time period generated by the time series generating algorithm may include:
按照时间序列生成算法产生的预设时间周期，在预设时间周期到时后，将故障业务单元所在的射频发送单元开启第二预定时间，通知所述故障业务单元的伙伴传输单元将失锁检测时间调整为第三预定时间，第二预定时间到时后，如果伙伴传输单元为锁定状态，所述故障业务恢复成功，清除定时器，如果第二预定时间到时后，伙伴传输单元为失锁状态故障业务恢复失败，关闭所述故障业务单元；如果业务未恢复成功，则等待下一个预设时间周期到达后，继续尝试恢复，直至业务恢复成功； According to the preset time period generated by the time series generation algorithm, after the preset time period expires, the radio frequency sending unit where the faulty service unit is located is turned on for a second predetermined time, and the partner transmission unit of the faulty service unit is notified to lose lock detection. The time is adjusted to a third predetermined time. After the second predetermined time expires, if the partner transmission unit is in the locked state, the faulty service is successfully restored, the timer is cleared, and if the second predetermined time expires, the partner transmission unit is lost. If the faulty service fails to be restored, the faulty service unit is shut down. If the service fails to be restored, wait for the next preset time period to arrive and continue to try to recover until the service is successfully restored.
其中，第三预定时间大于第二预定时间；Wherein the third predetermined time is greater than the second predetermined time;
举例说明，当传输单元所在的中频接收单元检测到该路业务持续失锁一段时间2s(即持续第一预定时间一直为失锁状态，传输单元认为当前业务故障)后，关闭对应传输单元的射频发送单元。按照时间序列生成算法产生的时间{10*1000，30*1000，60*1000，2*60*1000，5*60*1000，12*60*1000，30*60*1000，72*60*1000，2*60*60*1000}启动定时恢复。For example, when the intermediate frequency receiving unit where the transmission unit is located detects that the service is continuously lost for a period of time 2s (that is, the first predetermined time is always in the lost lock state, and the transmission unit considers that the current service is faulty), the radio frequency of the corresponding transmission unit is turned off. Sending unit. Time generated by the time series generation algorithm {10*1000, 30*1000, 60*1000, 2*60*1000, 5*60*1000, 12*60*1000, 30*60*1000, 72*60*1000 , 2 * 60 * 60 * 1000 } start timing recovery.
为了节约恢复所浪费的能量，本公开所采用的一个逐渐递增的时间序列进行定时恢复。In order to save energy wasted by recovery, the timing recovery is performed by a gradually increasing time series employed in the present disclosure.
在定时到时后尝试打开传输单元所在的射频发送单元5s(第二预定时间)，通知伙伴传输单元将失锁检测时间调整为10s(持续第三预定时间一直为失锁状态，传输单元认为当前业务故障)，5s到时后如果伙伴传输单元为锁定状态，故障业务恢复成功清除定时器，如果5s到时后如果伙伴传输单元为失锁状态故障业务恢复失败，关闭射频发送单元，按照时间序列重新启动定时等待下次尝试恢复，当对端传输单元检测到锁定后打开射频发送单元。After timing, the RF transmitting unit 5s (second predetermined time) in which the transmission unit is located is attempted to notify the partner transmission unit to adjust the loss detection detection time to 10 s (the third predetermined time is always in the unlocked state, and the transmission unit considers the current Service failure), if the partner transmission unit is locked after 5s, the fault service recovery succeeds in clearing the timer. If the partner transmission unit fails to lock the service after the 5s expires, the radio transmission unit is closed, according to the time series. The restart timing waits for the next attempt to recover, and the radio transmission unit is turned on when the peer transmission unit detects the lock.
当所述故障业务单元为MIMO抵消功能的业务单元时，所述伙伴传输单元为另一个MIMO抵消功能的业务单元，当所述故障业务单元为XPIC抵消功能的业务单元，所述伙伴传输单元为另一个XPIC抵消功能的业务单元。When the faulty service unit is a service unit of a MIMO cancellation function, the partner transmission unit is a service unit of another MIMO cancellation function, and when the faulty service unit is a service unit of an XPIC cancellation function, the partner transmission unit is Another business unit for XPIC cancellation functionality.

关闭先出现故障的MIMO抵消功能的故障业务单元，将后出现故障的MIMO抵消功能的故障业务单元打开，并关闭故障业务单元的MIMO抵消功能业务单元；本公开实施例是在故障业务单元为两个MIMO抵消功能的业务单元，则关闭先故障的MIMO抵消功能的业务单元，将后故障的MIMO抵消功能的业务单元打开，同时，关闭故障业务单元(该故障业务单元包括上述两个假设为故障的MIMO抵消功能的故障业务单元)的MIMO抵消功能业务单元。然后，按照时间序列生成算法产生的预设时间周期进行定时恢复，打开出现故障的 MIMO抵消功能的故障业务单元尝试主动恢复，如果业务恢复成功，则结束；如果业务未恢复成功，则等待下一个时间周期继续尝试恢复，直至业务恢复成功；Turning off the faulty service unit of the faulty MIMO canceling function, turning on the faulty service unit of the faulty MIMO canceling function, and turning off the MIMO canceling function service unit of the faulty service unit; the embodiment of the present disclosure is that the faulty service unit is two The service unit of the MIMO cancellation function closes the service unit of the MIMO cancellation function of the first failure, opens the service unit of the MIMO cancellation function of the later failure, and simultaneously closes the faulty service unit (the faulty service unit includes the above two assumptions as faults) The MIMO cancellation function of the faulty service unit) of the MIMO cancellation function business unit. Then, according to the preset time period generated by the time series generation algorithm, the timing recovery is performed, and the faulty fault is opened.

If the service is not successfully restored, it waits for the next time period to continue to try to recover until the service is successfully restored.

Then, the timing recovery is performed according to the preset time period generated by the time series generation algorithm, and the faulty service unit that opens the faulty XPIC cancellation function attempts to actively recover, and if the service recovery is successful, the process ends; if the service is not restored successfully, the next one is awaited. The time period continues to try to recover until the business is successfully restored.
当故障业务单元为一个XPIC抵消功能的业务单元和一个MIMO抵消功能的业务单元时，按预设时间周期对故障业务单元进行主动恢复，可以包括：When the faulty service unit is a service unit of the XPIC cancellation function and a service unit of the MIMO cancellation function, the active recovery of the faulty service unit according to the preset time period may include:
关闭故障的XPIC抵消功能的故障业务单元和故障的MIMO抵消功能的故障业务单元，并关闭故障的XPIC抵消功能的故障业务单元的XPIC抵消功能业务单元，以及故障的MIMO抵消功能的故障业务单元的MIMO抵消功能业务单元；Turn off the faulty XPIC cancellation function of the faulty service unit and faulty MIMO cancellation function of the faulty service unit, and turn off the faulty XPIC cancellation function of the faulty service unit of the XPIC offset function unit, and the faulty MIMO offset function of the faulty service unit MIMO cancellation function business unit;
按照时间序列生成算法产生的预设时间周期进行定时恢复，打开出现故障的XPIC抵消功能的故障业务单元和故障的MIMO抵消功能的故障业务单元尝试主动恢复，如果业务恢复成功，则结束；如果业务未恢复成功，则等待下一个时间周期继续尝试恢复，直至业务恢复成功。The timing recovery is performed according to a preset time period generated by the time series generation algorithm, and the faulty service unit that opens the faulty XPIC cancellation function and the faulty service unit of the faulty MIMO cancellation function attempt to actively recover, if the service recovery is successful, the service ends; If the recovery is not successful, wait for the next time period to continue to try to recover until the service is successfully restored.
也就是说，MIMO组主路信号和干扰信号强度基本一样，一个方向故障会引起另个方向基本同时中断，为了防止一个方向故障对另一个方向的影响，当 一个方向故障持续时间先达到2s后会先关闭PA，另一个方向就不会关闭PA，同时将两个方向的MIMO抵消功能关闭，防止互相干扰，如图6所示。That is to say, the main signal of the MIMO group and the intensity of the interference signal are basically the same, and one direction of the fault will cause the other direction to be interrupted substantially simultaneously, in order to prevent the influence of one direction of the fault on the other direction, when In one direction, the fault duration will first turn off the PA after 2s, and the PA will not be turned off in the other direction. At the same time, the MIMO cancellation function in both directions is turned off to prevent mutual interference, as shown in Figure 6.
当主用极化方向业务单元故障时，必然会引起空间主用极化方向业务单元中断，所以本公开采用在主用极化方向业务单元故障持续时间达到第一预定时间后，先关闭主用极化方向业务单元，但是会开启空间主用极化方向业务单元，同时将主用极化方向业务单元与空间主用极化方向业务单元两个方向的MIMO抵消功能关闭，防止互相干扰。When the primary polarization direction service unit fails, the space primary polarization direction service unit is inevitably interrupted. Therefore, the disclosure uses the primary polarization pole after the service duration of the active polarization direction reaches the first predetermined time. The service unit is oriented, but the space primary polarization direction service unit is turned on, and the MIMO cancellation function in both directions of the primary polarization direction service unit and the space primary polarization direction service unit is turned off to prevent mutual interference.
举例来说，假设主用极化方向业务单元方向故障发生失锁，进而会引发空间主用极化方向业务单元方向的失锁，主用极化方向业务单元方向失锁达到2s的时候，会关闭PA防止对伙伴的干扰，当空间主用极化方向业务单元方向失锁达到2s的时候，发现主用极化方向业务单元方向已经关闭PA，则保持自己的PA为打开，同时检测到自己和伙伴都处于失锁状态，为了便于恢复，要将MIMO抵消功能关闭，防止伙伴过来的干扰信号。For example, if the direction of the service direction of the primary polarization direction is lost, the loss of the direction of the service unit in the direction of the primary polarization will be caused. When the direction of the service unit in the primary polarization direction is lost for 2 seconds, Turn off the PA to prevent interference to the partner. When the direction of the service direction of the primary polarization direction of the space reaches 2s, it is found that the direction of the service unit in the primary polarization direction has been turned off, then keep the PA open and detect itself. Both the partner and the partner are in an unlocked state. In order to facilitate recovery, the MIMO cancellation function is turned off to prevent interference signals from the partner.
实施时，本公开实施例所述打开出现故障的XPIC抵消功能的故障业务单元和故障的MIMO抵消功能的故障业务单元尝试主动恢复，可以包括：When implemented, the faulty service unit that opens the faulty XPIC cancellation function and the faulty service unit of the faulty MIMO cancellation function, which is attempted to actively recover, may include:
将故障的XPIC抵消功能的故障业务单元和故障的MIMO抵消功能的故障业务单元打开，且故障的XPIC抵消功能的故障业务单元与故障的MIMO抵消功能的故障业务单元进行同步恢复。The faulty service unit of the faulty XPIC cancellation function and the faulty service unit of the faulty MIMO cancellation function are turned on, and the faulty service unit of the faulty XPIC cancellation function is synchronously restored with the faulty service unit of the faulty MIMO cancellation function.
MIMO和XPIC异常流程相互独立，当某个方向发生故障时，MIMO模块和XPIC模块会同时将PA关闭，并且将各自伙伴的MIMO和XPIC抵消信号关闭，为了保证故障消失后链路能快速恢复，MIMO和XPIC需要同时进行主动恢复，本公开采用的是联动恢复的机制，当XPIC模块做主动恢复的时候，MIMO模块监听XPIC模块进行同步恢复，使链路能够快速的恢复正常，如图7所示，MIMO+XPIC联动恢复包括：The MIMO and XPIC exception processes are independent of each other. When a direction fails, the MIMO module and the XPIC module simultaneously turn off the PA and turn off the MIMO and XPIC cancellation signals of the respective partners. To ensure that the link can recover quickly after the fault disappears, MIMO and XPIC need to perform active recovery at the same time. The present disclosure adopts a mechanism of linkage recovery. When the XPIC module performs active recovery, the MIMO module monitors the XPIC module for synchronous recovery, so that the link can be quickly restored to normal, as shown in Figure 7. Show that MIMO+XPIC linkage recovery includes:
假设当XPIC和MIMO都处于自动模式并且主用极化方向业务单元方向已经失锁很长一段时间后，此时主用极化方向业务单元方向的故障恢复，并尝试 打开PA；当XPIC模块开始尝试打开PA的时候，MIMO模块联动开始尝试打开PA，并且次用极化方向业务单元方向尝试恢复XPIC抵消功能，空间主用极化方向业务单元方向开始尝试恢复MIMO抵消功能，恢复成功则流程结束，如果恢复不成功，则XPIC模块继续恢复，MIMO模块继续联动恢复。Suppose that when both XPIC and MIMO are in the automatic mode and the direction of the service direction of the primary polarization direction has been lost for a long period of time, the fault in the direction of the service unit in the primary polarization direction is recovered and an attempt is made. The PA is turned on; when the XPIC module starts to try to open the PA, the MIMO module linkage starts to try to open the PA, and the secondary polarization direction service unit direction attempts to restore the XPIC cancellation function, and the spatial primary polarization direction service unit direction starts to try to restore the MIMO offset. Function, if the recovery is successful, the process ends. If the recovery is unsuccessful, the XPIC module continues to recover, and the MIMO module continues to recover.
本公开所述的各个预定时间和时间周期都可根据实际需要进行任意设定。Each predetermined time and time period described in the present disclosure can be arbitrarily set according to actual needs.
本公开的MIMO+XPIC技术中，XPIC和MIMO模式可以分别配置，在实测中XPIC强制MIMO自动模式下可以达到更快的恢复速度，MIMO与XPIC可以实现同步恢复。In the MIMO+XPIC technology of the present disclosure, the XPIC and MIMO modes can be separately configured, and in the actual measurement, the XPIC forced MIMO automatic mode can achieve faster recovery speed, and MIMO and XPIC can achieve synchronous recovery.
综合来说，本公开能在一路或几路业务出现故障的情况下，避免对另几路业务造成干扰，保证剩余链路业务的正常传输，最大限度地保证传输容量，并能在故障恢复正常传输能力后恢复故障业务。In summary, the present disclosure can avoid interference to other services in the case of a fault in one or several services, ensure normal transmission of the remaining link services, maximize transmission capacity, and restore normal faults. The faulty service is recovered after the transmission capability.
