Description

信号发送方法和装置 技术领域
本申请涉及通信技术领域。
背景技术
从2G系统到4G系统早期时代，蜂窝移动通信系统主要服务对象为手机，即由人持有的移动终端设备类型。随着移动互联网以及物联网的高速发展，从4G系统后期开始至今，蜂窝移动通信系统技术演进过程中考虑以及支持的物联网应用场景越来越丰富，相应地更多种类的物联网设备终端类型得到支持并落地于实际的网络部署和服务应用中，例如，增强型机器类型通信(enhanced Machine-Type Communication，eMTC)类型终端设备，窄带物联网(Narrow Band Internet of Things，NB-IoT)类型终端设备，减少能力(RedCap)类型终端设备等。随着物联网终端设备类型多样性的加强，蜂窝移动系统具有了越来越强的、面向垂直行业的业务提供和服务能力。
但是，在海量物联网设备中，庞大数量且更低成本的物联网终端设备领域还是蜂窝移动通信系统的空白。为了能够提供更稳健、更可靠也更完整的物联网应用解决方案，如何在3GPP蜂窝移动系统中支持更低成本物联网终端设备成为亟待解决的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
射频识别(Radio Frequency Identification，RFID)系统是面向庞大数量且更低成本的物联网终端设备领域的解决方案。RFID系统应用较为广泛。RFID系统的优点为标签成本较低、价格便宜。RFID标签尺寸小，对其所应用的物品的尺寸、材质等限制较小，因此较易于应用于各种物品管理、物品追踪等场景。虽然RFID标签成本低，但RFID系统的部署成本和使用成本相较于广域商业网络偏高。部署方面，RFID系统通常为局部部署，专网专用，部署成本很难得到有效的分摊。使用方面，若采用人工手持标签读写器方案，人力成本可能成为使用成本的主要开销且很难降低；若采用 专用的RFID端口或者网关读取和管理，又会明显增加部署成本。此外，RFID系统逻辑架构简单，无线资源管理松散，例如较难对无线电波传输中的干扰较好地进行协调等，因此RFID系统的系统容量和频谱使用效率普遍较低。
相比于现有的RFID系统，如果能够利用现有的商业移动通信蜂窝网络(例如LTE系统，5G NR系统等)支持需要标签类型互联网终端设备的行业应用，则可有效降低部署成本，进而降低该类型物联网设备部署门槛。除此以外，现有的商业移动通信蜂窝网络(例如LTE系统，5G NR系统等)在网络安全性和无线资源管理有效性方面远高于现有的RFID系统。
以5G系统为例，5G系统可以提供高安全等级鉴权、网络协调以及准确且稳定的终端设备管理机制，可以安全有效地减少使用中的人力成本，进而降低该类型物联网的使用成本，还可以基于此优化网络提高系统容量和频谱使用效率。部署成本和使用成本的降低，可以有效推进标签类型互联网终端设备在商业管理以及工业制造中的应用，加快相关行业的数字化进程、提高生产效率，并最终更有效地促进社会发展。
作为5G系统中的一种新的物联网终端类型，标签类型互联网终端设备(Ambient IoT设备，A-IoT设备)成本严重受限。设备的硬件能力明显弱于普通智能手机以及其它现有蜂窝移动通信系统所支持的物联网类型设备。例如，标签类型互联网终端设备可能没有稳定电源供电(如，采用环境能量收集代替常规电池)，带宽较窄，内部搭载的晶振因成本限制而精度受限，以及信号处理能力有限。
此外，由于Ambient IoT device(A-IoT设备)有限的设备能力，如何提高Ambient IoT系统的覆盖能力也是亟需解决的问题。为了解决该问题，可以在gNB(网络设备)与device(终端设备)之间增加中间节点(intermedia node)从而提高网络的覆盖能力。然而，对于拓扑结构中需要中间节点的场景，如何使中间节点知道如何向A-IoT设备发送信号或者接收来自A-IoT设备的信号，接收或者发送信号所在的资源以及发送或者接收信号的对象等信息是关键问题，从而保证网络侧发送的信号能够被A-IoT设备接收以及A-IoT设备发送的信号能够被网络侧接收。
针对上述问题的至少之一或其他类似问题，本申请实施例提供了一种信号发送方法和装置。
根据本申请实施例的一方面，提供一种信号发送方法，所述方法包括：

其中，所述第三信号为所述第一设备向第一终端设备发送的信号，所述第四信号为所述第一设备从第二终端设备接收的信号。
根据本申请实施例的另一方面，提供一种信号发送装置，应用于第一设备，包括：

其中，所述第三信号为所述第一设备向第一终端设备发送的信号，所述第四信号为所述第一设备从第二终端设备接收的信号。
本申请实施例的有益效果之一在于：根据本申请实施例，解决了在具有第一设备(intermedia UE)的ambient IoT系统的拓扑结构中，第一设备(intermedia UE)接收来自网络设备的信息比特(第一信号承载的信息比特)，如何生成发送给终端设备(device)的信号(第三信号)，以及第一设备(intermedia UE)接收来自终端设备(device)的信息比特(第四信号承载的信息比特)，如何生成发送给网络设备的信号(第二信号)。

在上述实现方式中，包含第三信息比特的信息比特，可以是直接包含第三信息比特的信息比特，也可以是基于第三信息比特经过编码和/或调制和/或加扰等处理后生成的信息比特。
根据上述实施例，不需要第一设备基于第三信息比特生成CRC校验比特，第一设备只需要对包含第三信息比特的信息比特进行线性编码/加扰/调制/信道编码等其他操作。网络设备发送给第一终端设备的数据对于第一设备是透明的，保证了数据传输的安全性。减少了第一设备在物理层处理R2D数据的流程，降低了第一设备的复杂度，进而降低了第一设备的能耗。
在上述实现方式中，在第三信息比特包括CRC校验比特的情况下，第一设备可以至少基于第三信息比特生成CRC校验比特，并基于该第三信息比特和该CRC校验比特生成第三信号。

在上述实现方式中，包含第三信息比特和CRC校验比特的信息比特，可以是直接包含第三信息比特和CRC校验比特的信息比特，也可以是基于第三信息比特和CRC校验比特经过编码和/或调制和/或加扰等处理后生成的信息比特。
根据上述实施例，虽然第三信息比特包括CRC校验比特，第一设备仍然基于该第三信息比特生成CRC校验比特，由此，在前述效果的基础上，进一步提高了传输的可靠性。
以上各个实施例仅对第一设备的下行相关处理(也即R2D方向)进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
下面对第一设备的上行相关处理(也即D2R方向)进行说明。图7是接收第四信号(或生成第四信息比特)的处理过程的一示意图。
在一些可能性的实现方式中，第一设备执行以下处理至少之一：
基于标准预先约定的和/或所述网络设备配置的上行信道编码方式，对至少包含所述第四信息比特的信息比特进行信道解码；
基于标准预先约定的和/或所述网络设备配置的上行调制方式，对至少包含所述第四信息比特的信息比特进行解调；
基于标准预先约定的和/或所述网络设备配置的上行线性编码方式，对至少包含所述第四信息比特的信息比特进行线性解码；
基于标准预先约定的和/或所述网络设备配置的扰码生成规则和/或解扰方式，对至少包含所述第四信息比特的信息比特进行解扰。
第一设备执行的上述处理(信道解码、解调、线性解码以及解扰)可以任意组合。
例如，第一设备执行上述信道解码、解调、线性解码以及解扰；再例如，第一设备执行上述信道解码、解调以及解扰；再例如，第一设备执行上述信道解码、解调以及线性解码；再例如，第一设备执行上述信道解码以及解调。本申请不限于此。
本申请实施例对第一设备执行上述处理(信道解码、解调、线性解码以及解扰)的执行顺序不做限制。
例如，第一设备可以先进行上述信道解码，再进行上述解调，然后进行上述线性解码，最后进行上述解扰；再例如，第一设备可以先进行上述信道解码，再进行上述解调，然后进行上述解扰，之后进行上述线性解码；再例如，第一设备可以先进行上述信道解码，再进行上述解调，然后进行上述解扰；再例如，第一设备可以先进行上述信道解码，再进行上述解调，再进行上述线性解码；再例如，第一设备可以先进行上述信道解码，再进行上述解调。以上只是举例说明，本申请对此不做限制。
在上述实现方式中，包含第四信息比特的信息比特，可以是直接包含第四信息比特的信息比特，也可以是基于第四信息比特经过编码和/或调制和/或加扰等处理后生成的信息比特。
在一些可能的实现方式中，第四信息比特包括CRC校验比特。
在上述实现方式中，第一设备还可以至少基于标准预先约定的和/或网络设备配置的CRC校验比特生成方式，对包含第四信息比特的信息比特进行CRC校验。
例如，第一设备先进行上述信道解码，再进行上述解调，然后进行上述线性解码，之后进行上述解扰，最后进行上述CRC校验；再例如，第一设备先进行上述信道解码，再进行上述解调，然后进行上述解扰，最后进行上述CRC校验；再例如，第一设备先进行上述信道解码，再进行上述解调，然后进行上述线性解码，最后进行上述CRC校验；再例如，第一设备先进行上述信道解码，再进行上述线性解码，然后进行上述解扰，最后进行上述CRC校验；再例如，第一设备先进行上述信道解码，再进行上述解调，最后进行上述CRC校验。
根据上述实施例，第四信息比特包含CRC校验比特，第一设备对包含第四信息比特的信息比特进行CRC校验，由此，检验了第二终端设备发送的信息比特(第四信息比特)的接收是否正确，从而避免了信息比特接收错误无法检测出来的情况，从而保证了信息接收的准确性。
在上述实现方式中，第二信号承载的信息比特可以包含第四信息比特，即第二信号承载的信息比特包含的CRC校验比特；或者，第二信号承载的信息比特包含第四信息比特去掉CRC校验比特之后的信息比特，即第二信号承载的信息比特不包含CRC校验比特。
根据上述实施例，在第二信号承载的信息比特包含第四信息比特的情况下，由于该第四信息比特包含了CRC校验比特，网络设备可以对第四信息比特再次进行校验， 进一步检验信息比特接收的正确性。
在一些可能的实现方式中，在第四信息比特包括CRC校验比特的情况下，第一设备也可以不对包含该第四信息比特的信息比特进行CRC校验。
例如，第一设备以任意可行的顺序进行以上处理(信道解码、解调、线性解码以及解扰)的任意组合，但是，不进行上述CRC校验的处理。
根据上述实施例，通过来自网络设备的信号(第一信号)承载与发送给第一终端设备的信号(第三信号)相关的配置信息，和/或承载与从第二终端设备接收的信号(第四信号)相关的配置信息，和/或承载由发送给第一终端设备的信号(第三信号)承载的信息比特(第三信息比特)，解决了第一设备接收来自网络设备的信息比特，如何生成发送给第一终端设备的信号(第三信号)，以及第一设备接收来自第二终端设备的信息比特，如何生成发送给网络设备的信号(第二信号)的问题，提高了通信的可靠性。
以上各个实施例仅对第一设备的上行相关处理(也即D2R方向)进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
在一些实施例中，第一设备还可以接收来自网络设备的与第一信号的接收和/或第二信号的发送有关的配置信息，该配置信息例如可以包括调制编码方案(MCS)表格相关的信息，时域资源信息，频域资源信息等。本申请对具体的配置方式不做限制。
在一些实施例中，第一设备还可以接收来自网络设备的调度信息，该调度信息用于指示第一设备接收上述第一信号，或者，该调度信息用于指示第一设备发送上述第二信号。本申请对具体的指示方式不做限制。
在前述各个实施例中，第一信号可以是物理层信息，也可以是MAC CE信令，还可以是RRC信令，或者上述信息/信令的任意组合，本申请对此不做限制。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
根据本申请实施例，解决了在具有第一设备(intermedia UE)的ambient IoT系统的拓扑结构中，第一设备(intermedia UE)接收来自网络设备的信息比特(第一信号承载的信息比特)，如何生成发送给终端设备(device)的信号(第三信号)，以及 第一设备(intermedia UE)接收来自终端设备(device)的信息比特(第四信号承载的信息比特)，如何生成发送给网络设备的信号(第二信号)。由此，提高了可靠性。
