图1是本申请适用的一种场景示意图，如图1所示，以基础覆盖为例，UE位于基站设备提供的一个或多个小区(也可以理解为，载波)的覆盖范围内，为UE服务的小区可以为一个或多个。当为UE的服务小区有多个时，UE可以按照载波聚合(carrier aggregation，CA)，或者双连接(dual connectivity，DC)，或者协作多点传输(coordinated multiple points，CoMP)方式工作，其中至少一个小区提供多于一种子载波间隔(numerology)同时为UE提供无线资源。以补充覆盖为例，UE也可以位于读写器(reader)提供的覆盖范围内，reader与UE之间的通信可以看做终端于终端之间的传输。终端或读写器与宏基站(可简称“宏站”)或者杆基站(可简称“杆站”)之间属于uu接口传输，即空口传输。
为了便于理解本申请的技术方案，下面首先对本申请涉及的若干技术名称进行简单的描述。
无线射频识别(radio frequency identification，RFID)：是一种非接触的自动识别技术，其基本原理是利用射频信号和空间耦合(例如，电感或电磁耦合)或雷达反射的传输特性，实现对被识别物体的自动识别。通常情况下，识别过程可以是：标签(tag)进入读写器(reader)(也可以理解为是，阅读器)后，接收读写器发出的射频信号，标签可以凭借感应电流所获得的能量发送出存储在芯片中的产品信息(例如，无源标签或被动标签)，或者由标签主动发送某一频率的信号(例如，有源标签或主动标签)，读写器读取信息并解码后，送至中央信息系统进行有关数据处理。
图2示出了RFID系统，如图2所示，一般情况下，一套完整的RFID系统，可以是 由读写器、电子标签及数据管理系统三个部分所组成。其工作原理是：读写器发射特定频率的无线电波能量用以驱动电路，从而将内部的数据送出，此时读写器便可以依序接收解读数据，送给应用程序做相应的处理。
RFID读写器：可以通过天线与RFID电子标签进行无线通信，可以实现对标签识别码和内存数据的读出或写入操作。如图2中的(a)所示，典型的阅读器包含有高频模块(例如，发送器或者接收器)、控制单元以及阅读器天线。RFID读写器也可以理解为是与标签通信的设备，形态可以为终端，也可以是基站，或者是一个具有读写功能的设备。
电子标签：由标签天线和标签专用芯片组成，如图2中的(b)所示。通常情况下，依据电子标签供电方式的不同，电子标签可以分为有源电子标签(active tag)、无源电子标签(passive tag)和半无源电子标签(semi-passive tag)。有源电子标签内装有电池，无源射频标签没有内接电池，半无源电子标签部分依靠电池工作。依据频率的不同，电子标签可以分为低频电子标签、高频电子标签、超高频电子标签和微波电子标签。当然，也可以依据封装形式的不同进行分类，此处不再详细介绍。对于无源标签也可以称为是无源的物联网设备(passive Internet of things，IOT)。因此，RFID电子标签也可以看成一种终端。
本申请中的“盘存”可以理解为：电子标签接收读写器指定的掩码信息和标志位后，若标签存储区的信息与收到的掩码信息匹配，以及标签保存的标志位与读写器指示的一致时，即可进入盘存流程中，即电子标签发起随机接入到读写器，并完成读写器相应的指令。
随着无线通信的快速发展，为满足和丰富人们的日益增长的需求，第五代移动通信(5G)系统应运而生。能够有效的应对未来爆炸性的移动数据流量增长，并支持海量的设备连接和不断涌现的各类新业务。
物联网(IoT)作为5G的组成部分，其市场需求增长迅猛。其中M2M，是机器与机器之间通过无线网络互相传递信息和数据的简称，是IoT发展的重要方向。现有物联网技术包括窄带(narrow band)物联网、低能力(reduced capacity，RedCap)用户设备等。但现有技术功耗依然是毫瓦量级以上的，没有办法进一步节省功耗。而无源RFID的技术可以实现微瓦级功耗和超低成本，成为蜂窝技术未来演进技术的一个重要分支。
如前所述，RFID可以用来追踪和管理很多领域的管理对象，具有准确率高、读取距离远、存储数据量大、耐用性强等特点，广泛应用于产品生产、物流、销售等环节中。但是，现有读写器对多个标签的交互过程是相同的，在盘存过程中，读写器无法识别不同类型的标签。根据盘存流程，标签随机接入成功之后，才可能将其能力信息发送给读写器。即，标签随机接入的效率较低，从而造成后续数据传输的性能较差。
有鉴于此，本申请提供了一种通信方法，可以基于标签的类型，选择不同的标签接入读写器，提高了标签和读写器之间的随机接入效率。并且，基于本申请的技术方案，读写器可以根据不同能力、类型的标签，使用不同的流程，或者配置不同的参数等，从而提高数据传输性能。

具体实施方式例如可以是：
作为一个示例，盘存指示信息#1中可以包含目标电子标签无源标签类型的信息。在一种可能的实现方式中，表明只读写器选择无源标签向读写器发起接入，或者只选择符合一定条件的无源标签向读写器发起接入。在另一种可能的实现方式中，该无源标签类型的信息可以指示，读写器可以支持无源标签的接入，即无源标签可以接入该读写器，也隐含指示也可能支持其他类型的标签接入，例如，该读写器也支持有源标签或者半无源标签的接入。
作为一个示例，盘存指示信息#1中可以包含目标电子标签半无源标签类型的信息。在一种可能的实现方式中，表明读写器只选择半无源标签向读写器发起接入，或者只选择符合一定条件的半无源标签向读写器发起接入。在另一种可能的实现方式中，该半无源标签类型的信息可以指示，读写器支持半无源标签的接入，即半无源标签可以接入该读写器，也隐含指示也可能支持其他类型的标签接入。
作为一个示例，盘存指示信息#1中还可以包含目标电子标签polar编码的信息。在一种可能的实现方式中，表明读写器支持polar编码的电子标签向读写器发起接入，或者读写器只选择符合一定条件的支持polar编码的电子标签向读写器发起接入。在另一种可能的实现方式中，该polar编码的信息表示，读写器支持polar编码的电子标签的接入，即支持polar编码标签可以接入该读写器，也隐含指示也可能支持其他类型的电子标签接入。
作为另一个示例，盘存指示信息#1中还可以包含目标电子标签认证指示的信息，在一种可能的实现方式中，是否需要注册流程可以与目标电子标签的类型绑定，例如，若盘存指示信息#1中包含目标电子标签的无源标签类型的信息，则表明该标签不需要认证注册流程；若盘存指示信息#1中包含目标电子标签的半无源标签类型的信息，则表明该类型标签需要执行认证注册流程。具体地，绑定可以为协议规定的关系。在另一种可能的实现方式中，目标电子标签是否需要注册流程可以与其标签类型相结合。例如，若盘存指示信息#1中包括注册流程的信息时，则无源电子标签不需要进行注册流程，半无源电子标签则需要进行注册流程；若盘存指示信息#1中不包括认证注册流程的信息时，则无源标签和半无源标签都不需要注册流程。在一种实现方式中，盘存指示信息#1中包含目标电子标签认证指示的信息，则表示选择接入的标签(也可以理解为，目标电子标签)都需要执行认证注册流程。
需要说明的是，本申请中，选择目标第二设备条件不仅仅限于上述描述的各个情况，还可以有其他情况，本领域人员可以根据实际情况灵活设定。并且还可以支持多种条件的结合，比如第一设备可以选择无源电子标签，且标识对应数值大于100的标签进行随机接入。

本步骤中，例如，读写器可以向电子标签发送选择(select)信令、询问(Query)信令、寻呼信令或者其他信令，等等。其中，第一指示信息中可以承载于上述信令中。
本申请中，如前所述电子标签可以有一个或者多个，该一个或者多个电子标签都可以接收盘存指示信息#1。由于盘存指示信息#1中包括第一信息，第一信息用于确定目标电子标签，因此，后续可以是由目标电子标签向读写器发起随机接入。
步骤404，目标电子标签向读写器发起随机接入请求。
例如，目标电子标签向读写器发送第一消息，进行随机接入。例如，该第一消息可以RN16信令或者随机数，等等。第一消息表明标签是符合读写器选择条件的标签，因此发送随机接入消息。
本申请中，该第一消息的名称可以是随机接入请求，或者也可以是盘存指示信息#1的响应消息，本申请对第一消息的具体名称不做限定。
作为一个示例，若盘存指示信息#1包含无源标签类型的信息，则表明只选择无源标签向读写器发起随机接入请求，或者只选择符合一定条件的无源标签向读写器发起随机接入请求。此时无源标签可以向读写器发起随机接入请求。在另一种实现方式中，该无源标签类型的信息表示，读写器支持无源标签的发起随机接入请求，即表明无源标签可以接入该读写器，也隐含指示该读写器也可能支持其他类型的标签发起随机接入请求。
作为一个示例，若盘存指示信息#1中包含半无源标签类型的信息，则表明只选择半无源标签向读写器发起随机接入请求，或者只选择符合一定条件的半无源标签向读写器发起随机接入请求。在另一种实现方式中，该半无源标签类型的信息，可以指示读写器支持半无源标签的发起随机接入请求，即表明半无源标签可以接入该读写器，也隐含指示也可能支持其他类型的标签接入。

在一些实施例中，还包括步骤405，读写器确定配置信息，该配置信息用于配置目标电子标签进行数据传输或者信令传输时所使用的信息。
在一种实现方式中，读写器可以基于盘存指示信息#1，确定配置信息。
在一种实现方式中，如果目标电子标签上报了能力信息，此时，读写器还可以基于目标电子标签能力信息确定配置信息。
在另一种实现方式中，读写器可以基于盘存指示信息和能力信息共同确定配置信息。
本申请中，配置信息可以包括以下至少一项：例如，认证注册指示信息、应用极化码指示信息、配置速率指示信息。其中，认证注册的指示信息可以用于指示目标电子标签在数据传输时需要向核心网发起注册流程；应用极化码指示信息可以用于指示目标电子标签在传输上行数据和/或下行数据时使用极化码进行数据传输；配置速率指示信息可以用于 指示目标电子在传输上行数据和/或下行数据中所使用的传输信息的速率或者码率。
基于上述技术方案，本申请中，目标第二设备随机接入时，还可以上报其能力信息，从而便于第一设备及时获取目标第二设备的能力信息，后续基于其能力信息确定数据传输所需的配置信息，从而提高传输性能以及传输可靠性。
步骤406，读写器向目标电子标签发送第二消息，该第二消息中包括配置信息。
例如，第二消息可以是冲突解决消息，或者，第二消息可以是肯定应答消息，等等。第二消息可以是根据第一指示信息确定的，比如，第一指示信息包含无源标签类型，表示选择无源标签接入，则可在第二消息中，对接入或者尝试接入的无源标签进行对应的配置。
步骤407，目标电子标签接收配置信息，根据配置信息进行上行数据传输。
根据本申请提供的方法，通过在盘存触发的命令中包含不同能力电子标签和不同类型电子标签指示信息，使得可以基于标签类型、能力发起随机接入过程。换句话说，读写器可以基于不同能力的电子标签或者不同类型的电子标签，选择不同的标签接入读写器。并且，读写器可以根据不同能力、类型的标签，使能不同的流程，或者配置不同的参数等，使得电子标签更好的传输数据，从而提高数据传输性能。
图5是本申请提供的通信方法500的示意图，如图5所示，该方法包括：
步骤501，数据网络向核心网发送盘存指示信息#2。
本申请中，盘存指示信息#2可以用于指示，选择一组标签随机接入该读写器，或者盘存指示信息#2用于指示所有标签都可以随机接入该读写器。
步骤502，核心网从数据网络接收盘存指示信息#2后，向读写器转发指示信息#2。
作为一个示例，核心网可以将该盘存指示信息#2先发送至基站，由基站再转发至读写器。若读写器就是基站时，则核心网可以直接发送至读写器。
步骤503，读写器收到盘存指示信息#2后，向标签发送盘存指示信息#2，
例如，该盘存指示信息#2可以承载于选择(select)信令、询问(Query)信令、寻呼信令或者其他信令中。
本申请中，在一种实现方式中，步骤501-步骤503为可选的。
步骤504，电子标签接收盘存指示信息#2后，向读写器发送第一消息，进行随机接入。
本申实施例中，第一消息中可以包括电子标签的能力信息，该能力信息包括以下一项或者多项：电子标签类型的信息(例如，无源电子标签类型、半无源电子标签类型、有源电子标签类型)、电子标签是否支持polar编码的信息、电子标签是否支持认证注册的信息。其中，第一消息表明标签符合读写器发送盘存指示的响应消息。
作为一个示例，例如，电子标签#1的能力信息可以包括以下信息的一项或者多项：电子标签#1为无源电子标签类型、电子标签#1支持polar编码、电子标签#1不支持认证注册。例如，电子标签#2的能力信息可以包括：电子标签#2为有源电子标签类型、电子标签#2支持polar编码、电子标签#2不支持认证注册。即，本实施例中，一个或者多个电子标签可以在随机接入过程中上报能力信息。例如，无源标签也可以表示不支持认证注册流程。
例如，电子标签随机接入过程中，以第一消息为RN16信令为例，RN16信令中可以包含电子标签的能力信息。其中，本申请中，RN16可以表示发送16位的随机数，对其信令名称不限制，也可以不叫RN16，本申请仅以RN16为例。
在一种实现方式中，第一消息可以是随机接入过程中的消息，也可以是随机接入成功后，第二设备能力上报的消息。
步骤505，读写器接收第一消息后，根据电子标签的能力信息确定电子标签的配置信息。
本申请中，配置信息可以包括以下至少一项：例如，认证注册指示信息、应用极化码指示信息、配置速率指示信息。其中，认证注册的指示信息可以用于指示电子标签在数据传输时需要向核心网发起注册流程；应用极化码指示信息可以用于指示电子标签在传输上行数据和/或下行数据时使用极化码进行数据传输；配置速率指示信息可以用于指示电子在传输上行数据和/或下行数据中所使用的传输信息的速率或者码率。
作为一个示例，以电子标签#1为例，读写器可以基于其能力信息确定其配置信息，例如，电子标签#1的配置信息可以是：数据传输时采用polar编码，电子标签#2在数据传输时不需要向核心网发起注册流程。另外，配置信息中还可以包括电子标签#2上行数据传输的速率。
步骤506，读写器向电子标签发送第二消息，该第二消息中包括电子标签的配置信息。
本申请中，该第二消息例如可以是肯定应答(acknowledge，ACK)消息，或者竞争解决消息，或者其他消息。
步骤507，电子标签接收到第二消息后，根据配置信息指示进行上行数据传输。
例如，如果读写器配置了注册流程，则被配置的电子标签需要发起注册流程。又例如，如果读写器配置了polar编码，则该电子标签可以向读写器发送数据时可以使用极化码，例如，在发送产品电子代码(electronic product code，EPC)时可以使用极化码。具体地，若指示上行支持polar编码，可以对其配置上行使用polar编码，比如配置码率等。也可以指示下行支持polar编码，并对其进行相应的配置。还可以，终端指示上行或者下行是否支持，或者都支持，基站配置上行或者下行或者都配置使用polar编码。
另外，读写器可以在发送盘存命令等消息中先发送对polar编码进行配置，比如码率等等，符合盘存命令选择或者接入条件的标签，将配置信息进行保存，标签后续上报自己的能力，基站向该标签发送可以应用前述发送的配置信息。示例性的，终端可以在第一消息中上报能力，基站可以在竞争解决消息中配置标签使用。
根据本申请提供的方法，通过电子标签在随机接入过程中，主动上报能力信息，使得读写器可以基于该标签的能力进行相应的配置。换句话说，电子标签在传输业务数据之前，可以先上报能力信息，使得读写器可以及时获取终端能力信息，对进行相应的配置，从而提高传输性能以及传输可靠性。
需要说明的是，在本申请中，“如果…时”以及“如果”均指在某种客观情况下设备会做出相应的处理，并非是限定时间，且也不要求设备实现时一定要有判断的动作，也不意味着存在其它限定。
