Description

一种共生网络中的资源配置方法及装置
本申请要求于2019年8月13日提交中国国家知识产权局、申请号为201910744124.3、发明名称为“一种共生网络中的资源配置方法及装置”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
本申请涉及共生网络领域，尤其涉及一种共生网络中的资源配置方法及装置。
背景技术
共生网络(symbiotic network)是一种主动通信系统和被动通信系统共存的无线通信网络。其中，主动通信系统为常规的无线通信系统(例如4G/5G和Wi-Fi)，被动通信系统为环境反向散射通信(ambient backscatter communication，AmBC)系统，被动通信系统通过反向散射主动通信系统的射频信号来传递数据。
基于蜂窝通信的共生网络是指主动通信系统为蜂窝系统的共生网络，(其中，AmBC终端设备通过反向散射蜂窝信号进行通信)。在这种共生网络中，为了提高AmBC通信质量，同时减少AmBC通信对蜂窝系统的干扰，蜂窝系统需要决定哪些时频资源上的蜂窝信号可以被AmBC终端设备反向散射(这些时频资源称为AmBC通信资源)。如图1所示的AmBC通信资源示意图，阴影部分的时频资源上调度了蜂窝通信，空白部分的时频资源上没有调度蜂窝通信。AmBC信号是通过加载到蜂窝通信的射频信号上进行发送的，方框内的阴影部分是AmBC通信资源，该时频资源上的蜂窝信号可以被AmBC终端设备反向散射。
为此，需要解决如何配置基于蜂窝通信的共生网络中的AmBC通信资源。
现有技术中采用的方法是主动通信系统为每个AmBC终端设备配置专用的AmBC通信资源(即per AmBC-UE资源配置)。这种方法存在以下问题：主动通信系统难以获取AmBC通信链路质量，因此很难有效地为每个AmBC终端设备分配资源；主动通信系统通常要经过多跳才能到达AmBC终端设备，因此，给每个AmBC终端设备都下发资源配置会带来大量的信令开销。
发明内容

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
首先描述本申请实施例涉及的几个术语：
共生网络
如图2所示的共生网络示意图，共生网络是指主动通信系统和被动通信系统共存的无线通信网络。其中，主动通信系统指常规的无线通信系统，例如，4G/5G、Wi-Fi、TV、广播等。这种通信系统中的设备，通过发射射频信号来传递数据。被动通信系统指环境反向散射通信(ambient backscatter communication，AmBC)系统。这种通信系统中的设备，自身不发射射频信号，而是通过反向散射(backscatter)主动通信系统的射频信号来传递数据。
AmBC技术原理
AmBC发射机通过调节天线阻抗，可以实现天线对环境中的射频信号(例如，蜂窝信号)的吸收或者反向散射，从而实现“0”或者“1”的发送。换言之，AmBC发射机是把自己的信号(低频信号)加载到环境中的射频信号(高频信号)上。
如图3所示的AmBC接收机提取AmBC信号的示意图，AmBC接收机对接收到的高频信号做滑窗平均，可以提取出AmBC信号(低频信号)。
AmBC通信具有零功耗、低成本、不占用额外频谱等特点，适用于物联网等应用场景。
本申请可应用于如图4所示的基于蜂窝通信的共生网络(即主动通信系统为蜂窝系统的共生网络)(以下简称“共生网络”)，也可应用于其它的共生网络，这里仅以基于蜂窝通信的共生网络为例进行描述。

网络设备：具备蜂窝通信功能(可以收发蜂窝信号)；
普通的终端设备：具备蜂窝通信功能(可以收发蜂窝信号)；
第一类型的AmBC终端设备：具备AmBC通信功能(可以收发AmBC信号)；
第二类型的AmBC终端设备：具备AmBC和蜂窝通信功能(可以收发AmBC和蜂窝信号)。
网络设备可以向普通的终端设备或者第二类型的AmBC终端设备发送蜂窝信号(即下行蜂窝通信)，普通的终端设备或者第二类型的AmBC终端设备也可以向网络设备发送蜂 窝信号(即上行蜂窝通信)。AmBC终端设备(包括第一类型的AmBC终端设备和第二类型的AmBC终端设备)可以通过反向散射蜂窝信号，向其他AmBC终端设备发送AmBC信号(即进行AmBC通信)。
其中：
蜂窝通信资源：指可以用于传输蜂窝信号的时频资源。
AmBC载波：指AmBC终端设备进行AmBC通信时所反向散射的蜂窝信号。可以作为AmBC载波的蜂窝信号有以下四种类型：
常规下行信号：网络设备所发射的携带下行蜂窝信息(包括蜂窝数据和蜂窝控制信令)的射频信号；
常规上行信号：普通的终端设备或者第二类型的AmBC终端设备所发射的携带上行蜂窝信息的射频信号；
下行激励载波：网络设备所发射的不携带蜂窝信息的射频信号(专用于为AmBC通信提供反向散射载波)；
上行激励载波：普通的终端设备或者第二类型的AmBC终端设备所发射的不携带蜂窝信息的射频信号(专用于为AmBC通信提供反向散射载波)。
AmBC通信资源：指可以用于传输AmBC载波的时频资源(即可以被AmBC终端设备反向散射的蜂窝信号所在的时频资源)。
上述网络设备可以是能和普通的终端设备通信的设备。网络设备可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、第五代(the fifth generation，5G)通信系统中的基站、未来通信系统中的基站或网络设备、WiFi系统中的接入节点、无线中继节点、无线回传节点等。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备还可以是小站，传输节点(transmission reference point，TRP)等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
上述的普通的终端设备是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上，如轮船上等；还可以部署在空中，如飞机、气球和卫星上等。所述终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。终端设备有时也可以称为用户设备(user equipment，UE)、接入终端设备、UE单元、移动站、移动台、远方站、远程终端设备、移动设备、终端(terminal)、无线通信设备、UE代理或UE装置等。
为解决以下问题：主动通信系统为每个AmBC终端设备配置专用的AmBC通信资源(即per AmBC-UE资源配置)，主动通信系统难以获取AmBC通信链路质量，因此很难有效地 为每个AmBC终端设备分配资源，另外，主动通信系统通常要经过多跳才能到达AmBC终端设备，因此，给每个AmBC终端设备都下发资源配置会带来大量的信令开销。本申请实施例提供一种共生网络中的资源配置方法及装置，通过根据本小区的AmBC资源池配置以及邻小区的AmBC资源池配置，确定本小区的AmBC资源集，通知本小区的AmBC终端设备该小区的AmBC资源集的信息，从而使得该小区的AmBC终端设备可以使用该小区的AmBC资源集进行AmBC通信，无需为每个AmBC终端设备配置AmBC通信资源，节省了资源配置的信令开销。
如图5所示，为本申请实施例提供的一种共生网络中的资源配置方法的流程示意图，该方法可以包括以下步骤：
S101、网络设备为第一小区配置第一小区的AmBC资源池。
网络设备包括一个或多个小区。每个小区内可以驻留有一个或多个普通UE，一个或多个第一类型的AmBC终端设备和/或一个或多个第二类型的AmBC终端设备可以通过反向散射该小区或邻小区发射的蜂窝信号进行通信。上述第一小区为网络设备中的任一个小区。网络设备为第一小区配置该小区可用的AmBC资源池。
具体实现中，网络设备给第一小区配置两种AmBC资源池：内向(inward)AmBC资源池(简称“内向资源池”)和外向(outward)AmBC资源池(简称“外向资源池”)。其中，内向资源池用于本小区AmBC终端设备发射信号(本小区AmBC终端设备，是指可以接收到本小区AmBC资源池配置信息的AmBC终端设备)，外向资源池用于非本小区AmBC终端设备发射信号。AmBC资源池中包括AmBC的通信资源，即可以用于传输AmBC载波的时频资源(即可以被AmBC设备反向散射的蜂窝信号所在的时频资源)。
第一小区的内向资源池，是指该小区中可以被本小区AmBC终端设备反向散射的蜂窝信号所在的时频资源。换句话说，一个小区的内向资源池应该具备以下特点：(1)该资源池是本小区蜂窝通信时频资源的一个子集；(2)小区在该资源池上发射的蜂窝信号，可以被本小区AmBC终端设备反向散射；(3)小区在非该资源池上发射的蜂窝信号，不能被本小区AmBC终端设备反向散射。
第一小区的外向资源池，是指该小区中可以被非本小区AmBC终端设备反向散射的蜂窝信号所在的时频资源。换句话说，一个小区的外向资源池应该具备以下特点：(1)该资源池是本小区蜂窝通信时频资源的一个子集；(2)小区在该资源池上发射的蜂窝信号，可以被非本小区AmBC终端设备反向散射。
一个小区配置的外向资源池，可以有以下使用方法：(1)本小区在此资源池上发射常规上行(uplink，UL)/下行(downlink，DL)信号，邻小区的AmBC终端设备可以反向散射该信号。例如，本小区在此资源上给本小区中心区域的蜂窝UE发送DL信号，那么该信号可以被邻小区AmBC终端设备反向散射，并且反向散射对接收该DL信号的蜂窝UE所产生的干扰很小。(2)邻小区可以在此资源池上发射UL/DL激励载波。
需要说明的是，同一小区的内向资源池和外向资源池，可以相互分离、部分重叠或者完全重叠。不同小区的内向资源池和外向资源池，可以相互分离、部分重叠或者完全重叠。资源池在时间上可以周期重复，也可以不重复。
具体地，网络设备为第一小区配置第一小区的AmBC资源池，可以通过以下方式进行 配置：
网络设备为自己的小区配置AmBC资源池；
网管系统为小区配置AmBC资源池，网络设备从网管系统下载该小区的AmBC资源池的配置。其中，该配置包括资源池类型和资源池包括的时频资源，资源池类型包括内向资源池和外向资源池。
S102、网络设备获取一个或多个第二小区的AmBC资源池配置，其中，一个或多个第二小区为第一小区的邻小区，AmBC资源池配置包括以下一个或多个信息：一个或多个第二小区的小区标识，每个第二小区的资源池类型、每种资源池包括的时频资源，资源池类型包括内向资源池和外向资源池。
根据上述外向资源池的特点，一个小区在该外向资源池上发射的蜂窝信号，可以被非本小区AmBC终端设备反向散射，因此，第一小区的AmBC终端设备可以利用本小区的内向资源池和邻小区的外向资源池进行AmBC通信；另外，第一小区的AmBC终端设备需要在本小区的内向及外向资源池和邻小区的内向及外向资源池接收其它AmBC终端设备反向散射的信号。因此，网络设备还需要获取与第一小区相邻的一个或多个第二小区的AmBC资源池配置。
具体地，S102包括：向所述一个或多个第二小区所属的网络设备发送AmBC资源池配置信息请求，所述AmBC资源池配置信息请求包括所述一个或多个第二小区的标识；以及接收AmBC资源池配置信息反馈，所述AmBC资源池配置信息反馈包括所述一个或多个第二小区的AmBC资源池配置。其中，AmBC资源池配置包括以下一个或多个信息：一个或多个第二小区的小区标识，每个第二小区的资源池类型、每种资源池包括的时频资源，资源池类型包括内向资源池和外向资源池。
具体地，第一小区所属的网络设备与一个或多个第二小区所属的网络设备之间可以通过网络设备之间的直连接口(例如，新无线(new radio，NR)系统的Xn接口)完成。
S103、网络设备根据第一小区的AmBC资源池配置、以及一个或多个第二小区的AmBC资源池配置，确定第一小区的AmBC资源集。
网络设备根据上述给第一小区配置的资源池以及从邻小区获取的资源池配置，确定第一小区的AmBC资源集。其中，第一小区的AmBC资源集是指第一小区的AmBC终端设备可以使用的AmBC通信资源，包括发射资源集和接收资源集。
具体地，对于一个小区而言，其AmBC发射资源集包括：本小区时频范围内的AmBC发射资源和本小区时频范围外的AmBC发射资源。其中，本小区时频范围内的AmBC发射资源，由本小区内向资源池确定；本小区时频范围外的AmBC发射资源，由邻小区外向资源池确定(也就是说，邻小区外向资源池中与本小区时频范围不重叠的部分，组成了本小区时频范围外的AmBC发射资源)。则S103包括：确定第一小区的发射资源集包括第一小区的内向资源池中的时频资源、和/或修正的一个或多个第二小区的外向资源池中的时频资源，其中，修正的一个或多个第二小区的外向资源池中的时频资源为未与第一小区的时频资源重叠的时频资源。
如图6所示的修正邻小区外向资源池的示意图，当邻小区的外向资源池中的时频资源与第一小区的时频资源有重叠时，需要对邻小区的外向资源池中的时频资源进行修正。如 图6左侧的修正前的示意图所示，邻小区的频率范围与本小区(第一小区)的频率范围(包括本小区的内向资源池和外向资源池)有重叠，具体地，阴影部分为邻小区的外向资源池中的频率范围，邻小区的外向资源池中的频率范围与本小区的频率范围重叠。需要对邻小区的外向资源池中的频率范围进行修正，具体是邻小区的外向资源池中的频率范围减去与本小区的频率范围重叠的部分。如图6右侧的修正后的示意图所示，修正后的邻小区的外向资源池中的频率范围去除了与本小区的频率范围重叠的部分。
小区中的AmBC终端设备，需要接收本小区及邻小区中的AmBC终端设备发射的信号，因此需要监听本小区及邻小区所有的AmBC发射资源。则S103还包括：确定第一小区的接收资源集包括第一小区的内向资源池中的时频资源、第一小区的外向资源池中的时频资源、一个或多个第二小区的内向资源池中的时频资源、和/或一个或多个第二小区的外向资源池中的时频资源。
S104、网络设备向AmBC终端设备通知第一小区的AmBC资源集的信息。
相应地，第二类型的AmBC终端设备接收上述第一小区的AmBC资源集的信息。
网络设备在确定第一小区的AmBC资源集后，要将该资源集的信息通知第一小区的AmBC终端设备，以使第一小区内的AmBC终端设备可以利用该资源集进行信号的接收和发送。
对于驻留在小区中或者已经接入小区的第二类型的AmBC终端设备，网络设备可以通过广播消息(例如，系统信息块(system information block，SIB))或者专用的无线资源控制(radio resource control，RRC)信令，将第一小区的AmBC资源集的信息发送给第二类型的AmBC终端设备。
S105、第二类型的AmBC终端设备广播第一小区的AmBC资源集的信息。
相应地，第一类型的AmBC终端设备接收第二类型的AmBC终端设备广播的一个或多个小区的AmBC资源集的信息。
第二类型的AmBC终端设备在接收到上述第一小区的AmBC资源集的信息后，可以通过反向散射该资源集上的蜂窝信号(即AmBC通信方式)，广播该资源集的信息。对于第一类型的AmBC终端设备，其没有蜂窝通信功能，因此，第一类型的AmBC终端设备在所有蜂窝频段上监听AmBC通信，然后接收到第二类型的AmBC终端设备广播的上述第一小区的AmBC资源集的信息。
S106、第一类型的AmBC终端设备对接收到的一个或多个小区的AmBC资源集的质量进行测量。
上述描述了第一类型的AmBC终端设备接收到第一小区的资源集的信息，实际上，AmBC终端设备由于没有蜂窝通信功能，并没有驻留到某个小区，因此，AmBC终端设备可以根据上述步骤接收到一个或多个小区的AmBC资源集的信息。第一类型的AmBC终端设备测量每个小区的AmBC发射资源集的质量。例如，测量每个小区的AmBC发射资源集上蜂窝信号的平均接收功率。
S107、第一类型的AmBC终端设备根据一个或多个小区的AmBC资源集的测量结果，选择所属的小区。
具体地，第一类型的AmBC终端设备根据测量结果，选取一个小区作为自己的小区。 例如，选取AmBC发射资源集质量最好的小区作为自己的小区。
S108、第一类型的AmBC终端设备确定选取的小区的发射资源集为AmBC发射资源集，以及确定接收到的一个或多个小区的接收资源集为AmBC接收资源集。
第一类型的AmBC终端设备，可以在自己小区的AmBC发射资源集上选取资源进行反向散射(即AmBC信号发射)，并在所有小区的AmBC接收资源集上监听并接收其他AmBC终端设备发射的AmBC信号(即AmBC信号接收)。
