技术领域
本公开涉及无线通信领域，具体而言，涉及控制无线通信网络或无线通信网络中的传感器的电子设备以及方法。
背景技术
超高可靠低延时通信(URLLC,Ultra-Reliable Low-Latency Communications)场景作为5G网络中的三大应用场景之一，其对数据传输的高可靠性和低延时都这两方面性能都有着极高的要求。一般来说，用户层面的延时应低于1毫秒，而误码率应低于10 -5。
信道编码是通信系统中的一个必要组成部分，其基本思想是通过在传输的数据中增加一定的冗余信息，使得接收端可以具备检错和纠错的能力，以降低数据传输的误码率，即提升通信的可靠性。在通信系统中使用不同的编码方案，可以实现不同的检错能力和纠错能力。信道编码方案可分为线性分组码、循环码、卷积码等等。
更多的冗余位可以更好地实现纠错，以降低误码率，但同时也会降低数据传输效率，导致传输所需的延时增加。因此，对于有限长信道编码，可以通过牺牲一定的可靠性来换取更高的吞吐量，使得数据传输的延时降低。然而，采用单一固定的有限长信道编码方案只能实现可靠性和延时之间固定的折中，因此难以灵活应对系统的环境变化和服务需求变化。
在无线传感器网络中，传感器实时产生新鲜数据需要上传到基站中。为了节约传感器的传输功率消耗，传感器可以将产生的数据上传给无线接入节点，然后由无线接入节点将数据重新打包并进行信道编码后，通过无线信道发送到基站中。
发明内容
为了使传感器的数据低延时和/或可靠地传输到基站中，本公开提出了根据无线接入节点的通信状态调整无线接入节点的信道编码方案和/或传感器的工作状态。本公开的方案可以降低从传感器到基站的数据传输延时和/或提高数据传输的可靠性。

在下文中，将参照附图详细地描述本公开内容的优选实施例。注意，在本说明书和 附图中，用相同的附图标记来表示具有基本上相同的功能和结构的结构元件，并且省略对这些结构元件的重复说明。
将按照以下顺序进行描述：
1.系统概述

3.设备配置
4.应用示例
<1.系统概述>
首先，将描述本公开的一些实施例的通信系统。图1是示出本公开的一些实施例的通信系统100的配置的示例的示意图。如图1所示，通信系统100包括部署在不同位置处的传感器101-1、101-2和101-3，无线接入节点102，基站103，以及核心网104。在本文中，在不需要区分传感器101-1、101-2和101-3的情况下，用标号101来表示传感器101-1、101-2和103-3中的任何一个。需要注意的是，图1中示出的传感器101的数量是示例，并且传感器101的数量不限于三个，可以是任何数量。
传感器101可以对环境进行监测以生成采样数据。传感器101所生成的采样数据需要低延时且高可靠地上传到基站103中。传感器101可以是诸如物联网(IoT)传感器之类的传感器，其可以帮助人们实现各种智能系统。例如，图像传感器能够用于监测道路违停的智慧停车应用系统、监测追踪异常人员、事件的城市安全监控系统。例如，专业的井盖传感器、温湿度传感器、烟雾报警器可以结合IoT来产生管井状态、温湿度、烟雾等的无线告警信息。通常，这些传感器需要低功耗IoT模块，以使其可以仅依赖有限电量的电池工作长达数年的时间，而不需要布置电线。在现实情况中，传感器101的自身电池容量有限。为了有更长的续航时间，需要尽可能地控制和降低传感器自身的功率消耗，其中包括传输数据带来的通信功率消耗。当传感器101和基站103之间的距离较远时，如果传感器101直接传输数据给基站103会产生很大的路径损耗。在这一情况下，若给定传感器的传输功率，则传感器101和基站103间通信的吞吐量会很低，进而造成传感器101收集到的数据无法及时发送到基站103。若为了保证目标传输速率，则会造成传输功率消耗过大，进而影响传感器101的续航时间。
本公开的一些实施例的通信系统100在传感器101附近部署与传感器进行无线通 信的无线接入节点102来实现中继节点的功能。传感器101先将生成的采样数据发送到无线接入节点102，然后由无线接入节点102重新对这些数据进行打包分组和信道编码后，再发送到与核心网104相连接的基站103中。此外，传感器101还可以向无线接入节点102发送控制信息或者从无线接入节点102接收控制信息。
无线接入节点102可以将从传感器101收集的采样数据发送给基站103。无线接入节点102可以由任何能够与基站103通信的设备实现。例如，无线接入节点102可以由用户设备(UE)实现。此外，在本公开的一些实施例中，无线接入节点102也可以具备传感器的功能，即能够对环境进行监测以生成采样数据。
基站103可以将从无线接入节点102接收的采样数据发送给核心网104。
图2是示出在本公开的一些实施例中从传感器的数据产生到基站的数据接收的数据传输延时的示意图。
在本公开的一些实施例中，传感器和无线接入节点的距离很近并且它们之间的吞吐量很高，例如，在高可靠性低延时通信(URLLC)场景中。传感器和无线接入节点间的短距离通信可以实现很高的传输吞吐量，使得传感器只需要花费很小的功率开销就可以将数据快速可靠地上传到无线接入节点中。因此，数据传输延时主要由无线接入节点中的排队延时和从无线接入节点到基站的空口延时决定。
排队延时是数据在缓存队列中的平均排队时间。根据排队论中的Little定理，数据在缓存队列中的平均排队时间取决于时间维度上的平均缓存中存放的数据量大小，即
Figure PCTCN2021102275-appb-000001
其中λ arrival为队列的平均达到率，而q[t]为当前时刻的队列长度，即缓存中数据量的大小。该结论说明无线接入节点的缓存中的数据量越多，则数据的平均排队时间越长，因而减少缓存中的数据量可以降低排队延时。为实现该目的，可以增大队列的输出率，即增大无线接入节点和基站之间的吞吐量；或者降低队列的输入率，即降低无线传感器采集和上传数据的速率。
从上述分析可以看出，无线接入节点的缓存状态也可以作为信道编码方案的切换依据。具体来说，在无线接入节点缓存中数据量较多的时候，可以通过提升传输功率或者信道编码方案来实现更高的吞吐量以控制延时。此外，还可以通过控制无线传感器的工作状态，比如降低采样率(如降低图像传感器的分辨率)，以降低延时。
空口延时取决于系统环境，包括信道状态、传输功率以及包括信道编码方案在内的 通信参数等。
<2.处理流程>
下面将描述传感器101、无线接入节点102和基站103之间的通信流程。图3是示出本公开的一些实施例的通信流程300的流程图。
在步骤S306，无线接入节点102获取自身的通信状态信息。在步骤S308，无线接入节点102根据自身的通信状态信息，选择与通信状态信息对应的目标信道编码方案。在步骤S310，无线接入节点102向基站103请求切换至目标信道编码方案。在步骤S312，基站103向无线接入节点102确认切换至目标信道编码方案。在步骤S314，无线接入节点102切换至目标信道编码方案。
在本公开的一些实施例中，可以省略步骤S310和S312。无线接入节点102可以不经基站103的确认就切换至目标信道编码方案。在省略步骤S310和S312的情况下，无线接入节点102可以发送信令通知基站103其已切换至目标信道编码方案。
在本公开的一些实施例中，无线接入节点102的通信状态信息可以包括无线接入节点的待发送的数据的缓存量、无线接入节点的待发送的数据的传输延时要求、无线接入节点的传入数据速率中的一项或多项。无线接入节点102可以根据其通信状态信息，选择具有与其通信状态信息对应的吞吐量的目标信道编码方案。
无线接入节点102中待发送的数据的缓存量越大，则需要越高吞吐量的信道编码方案。高吞吐量的信道编码方案可以使得无线接入节点102能够尽快将缓存的数据发送给基站103，从而避免数据积压在缓存中。无线接入节点102可以将其待发送的数据的缓存量划分为多个级别，并根据其待发送的数据的缓存量的级别，选择与该级别对应的目标信道编码方案。
无线接入节点102中待发送的数据的传输延时要求越高，则需要越高吞吐量的信道编码方案。数据的传输延时要求高，说明该数据需要尽快发送给基站103，以避免数据由于时间的流逝而失效。例如，无线接入节点102可以选择目标信道编码方案使得其待发送的数据的排队延时满足其待发送的数据的传输延时要求。
无线接入节点102的传入数据速率越高，则需要越高吞吐量的信道编码方案。传入数据速率高，说明数据到达无线接入节点102的速率很高。高吞吐量的信道编码方案可以避免数据积压在缓存中而造成排队延时过大。无线接入节点102可以将其传入数据速率划分为多个级别，并根据其传入数据速率的级别，选择与该级别对 应的目标信道编码方案。
在本公开的一些实施例中，无线接入节点102的通信状态信息可以包括无线接入节点用于发送数据的信道的状态、无线接入节点的待发送的数据的传输可靠性要求、多址接入方案、调制方案、免授权方式中的一项或多项。无线接入节点102可以根据其通信状态信息，选择具有与其通信状态信息对应的可靠性的目标信道编码方案。
在一些情况下，无线接入节点102用于发送数据的信道的状态较差或者其待发送的数据的传输可靠性要求较高。无线接入节点102可以选择可靠性较高的信道编码方案，以保证数据传输的可靠性。
在一些情况下，无线接入节点102使用的多址接入方案是诸如非正交多址接入(NOMA)和多用户MIMO之类的能保证高吞吐量的多址接入方案，或者使用的调制方案是诸如1024-QAM之类的高阶调制方案。由于吞吐量已经可以通过多址接入方案或者调制方案来保证，因而可以采用高可靠性的信道编码方案。反之，对于一些吞吐量较低的多址接入方案或调制方案，可以采用可靠性更小而吞吐量更高的信道编码方案。
在一些情况下，无线接入节点102使用免授权方式(Grant-free method)，即无线接入节点无需gNB授权，直接进行数据传输，从而缩短上行链路的信令延时。免授权方式可能会增加信号干扰，为了保证数据传输的可靠性，可以选择高可靠性的信道编码方案。否则，可以选择诸如BCH码之类的可靠性较低的信道编码方案。
在本公开的一些实施例中，无线接入节点102的通信状态信息可以包括无线接入节点的待发送的数据包的大小。无线接入节点102可以选择适于传输待发送的数据包的大小的信道编码方案。在待发送的数据包较小的情况下，可以选择诸如BCH码和极化码(Polar Code)之类的具有较短码长的信道编码方案。在待发送的数据包较大的情况下，可以选择诸如LDPC之类的在码长较长时可以获得高编码增益的信道编码方案。
在本公开的一些实施例中，无线接入节点102可以选择目标信道编码方案的类型、目标信道编码方案的码长和选择目标信道编码方案的编码率中的一项或多项，以使所选择的目标信道编码方案的吞吐量、可靠性或者码长与通信状态信息对应。
在实际系统中，无线接入节点102的通信状态通常是动态变化的。相应地，无线接入节点102可以根据其实时通信状态动态调整其信道编码方案。例如，无线接 入节点102可以周期性地获取其通信状态信息，并选择与新获取的通信状态信息对应的目标信道编码方案。
例如，无线接入节点102用于发送数据的信道的状态通常会随时间而变化，其当前信道状态可能时好时坏。无线接入节点102的待发送的数据的传输可靠性要求可能也会动态变化。例如，如果传感器检测到异常值，则可能会对低延时和高可靠性提出更加严格的要求。反之，如果传感器检测到的数据稳定，则可以降低对低延时和高可靠性的要求。
此外，无线接入节点102还可以获得通信状态的统计信息，并根据该统计信息，提前预测如何调整信道编码方案。
例如，无线接入节点102的传入数据速率会随时间而变化。传感器101产生并上传数据的过程存在随机性，即每个时隙中无线接入节点102收到的数据量是随机的。由于传感器101的个数有限且位置分布固定，因此无线接入节点102可以获得传感器101产生并上传数据的统计分布。无线接入节点102可以根据数据产生的统计分布信息提前预测如何调整信道编码方案。
此外，无线接入节点102的待发送的数据的缓存量也会随时间而变化。当前时隙的缓存量主要取决于相邻时隙的缓存量，也就是具备一定的马尔可夫性。当前时隙下的缓存量相比上一时隙的变化，取决于新数据的到达和发送，其中前者为随机变量，后者取决于无线接入节点和基站之间的吞吐量。无线接入节点102可以根据缓存量的马尔可夫性提前预测如何调整信道编码方案。
此外，无线接入节点102还可以以负反馈方式调整信道编码方案。在一些情况下，在无线接入节点102切换到高吞吐量的信道编码方案之后，由于其待发送的数据的缓存量降低，从而会导致排队延时降低。此时，无线接入节点102可以切换到高可靠性的信道编码方案，以保证数据传输的可靠性。
图4是示出在本公开的一些实施例中以负反馈方式调整信道编码方案的示意图。在步骤S402，无线接入节点102估计其排队延时高。该排队延时可以根据无线接入节点的数据的缓存量以及吞吐量来估计，或者可以根据无线接入节点102接收数据和发送数据的时间差来估计。在步骤S404，无线接入节点102选择并切换至更高吞吐量的信道编码方案，以降低数据的排队延时。在步骤S406，无线接入节点估计其排队延时低。在步骤S408，无线接入节点102选择并切换至更高可靠性的信道编码方案，以保证数据传输的可靠性。通过以上述负反馈的方式调整无线接入节点102的信道编码方案，可以在吞吐 量和可靠性之间获得平衡，从而使得无线接入节点102的当前信道编码方案适应数据传输的要求。
以上是无线接入节点102调整其信道编码方案以适应数据传输的要求的流程。此外，传感器101可以调整其工作状态来适应数据传输的要求。
由于传感器收集的是环境信息，所以评价传感器数据是否有用的标准之一是信息的“新鲜程度”，该标准可以用信息年龄的概念来衡量。以温度传感器为例，该传感器被部署在某一位置感知该位置时变的温度，并需要把收集到的温度信息发送给基站。如果该传感器采样率很高，任何温度变化都可以很快被传感器检测到，但也会随之产生较高的数据量。如果因此导致数据过多而无法及时发送给基站，反而会造成基站无法及时得知温度变化的信息。所以从这个角度来看，传感器的采样率并非越高越好，而是需要兼顾数据产生到被基站接收之间的延时在可接受范围内。此外，传感器设备的电池容量有限，所以传感器在一些情况下可以进入休眠状态来节约设备能耗。
在无线接入节点的待发送的数据的缓存量较大时，由于任何新上传的数据都需要很长的排队时间才能被发送到基站，因此对数据更新频率要求不高的传感器可以选择进入休眠状态，暂时停止对环境信息的采样以节省功耗。在无线接入节点的待发送的数据的缓存量变小后，传感器102重新进入采样状态。
回到图3，在步骤S316，传感器101获取无线接入节点102的通信状态信息。在步骤S318，传感器101根据无线接入节点102的通信状态信息，选择与该通信状态信息对应的传感器的目标工作状态。在步骤S320，传感器101切换至目标工作状态。该目标工作状态包括休眠或者多个采样率中的一个采样率。
在本公开的一些实施例中，通信状态信息包括无线接入节点102的待发送的数据的排队延时。在本公开的一些实施例中，通信状态信息包括无线接入节点102的待发送的数据的缓存量和吞吐量，传感器101可以根据无线接入节点102的待发送的数据的缓存量和吞吐量估计无线接入节点102的待发送的数据的排队延时。在排队延时较大的情况下，传感器101可以选择较低的采样率，或者进入休眠状态。在排队延时较小的情况下，传感器101可以恢复采样或者选择较高的采样率。传感器101可以将无线接入节点102的待发送的数据的排队延时划分为多个级别，并根据无线接入节点102的排队延时的级别，选择与该级别对应的目标工作状态。
此外，类似于无线接入节点102，传感器101可以获取无线接入节点102的实时通信状态并动态调整传感器101的工作状态。例如，传感器101可以周期性地获取无 线接入节点102的通信状态信息，并选择与新获取的通信状态信息对应的工作状态。
此外，传感器101还可以以负反馈方式调整信道编码方案。在一些情况下，在传感器101休眠或者降低采样率之后，由于无线接入节点102的待发送的数据的缓存量降低，从而会导致排队延时降低。此时，可以使得传感器101恢复采样或者提高采样率，以提高传感器的数据分辨率。
图5是示出在本公开的一些实施例中以负反馈方式调整传感器的工作状态的示意图。在步骤S502，传感器101估计无线接入节点102中的数据的排队延时高。在步骤S504，传感器101休眠或者降低采样率，以降低无线接入节点102中的数据的排队延时。在步骤S506，传感器101估计无线接入节点102中的数据的排队延时低。在步骤S508，传感器101恢复采样或者提高采样率，以提高采样数据的分辨率。通过以上述负反馈的方式调整传感器101的工作状态，可以在采样数据的分辨率和数据延时之间获得平衡，从而使得传感器101的当前工作状态适应数据传输的要求。
此外各个传感器的工作状态的调整可以独立地进行，无需各个传感器之间的协同。这种方式可以节省信令开销和处理计算量。
需要注意的是，图3中的通信流程300可以省略一个或多个步骤。通信流程300可以选择调整无线接入节点102的信道编码方案和传感器101的工作状态二者，也可以选择仅调整调整无线接入节点102的信道编码方案和传感器101的工作状态之一。例如，可以省略步骤S316、S318和S320以仅调整无线接入节点102的信道编码方案。例如，可以省略步骤S306、S308、S310、S312和S314以仅调整传感器101的工作状态。
