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)支持需要标签类型物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物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，标签类型物联网终端设备(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，标签类型物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，简称为device或终端设备)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向A-IoT设备发送信号或者接收来自A-IoT设备的信号的时域资源是关键问题，从而避免中间节点在收发网络侧的信号和device侧的信号之间发生冲突，进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：
第一设备接收来自网络设备的第一信号，所述第一信号至少包括与第三信号和/或第四信号相关的时域资源信息；
所述第一设备向所述网络设备发送第二信号，所述第二信号至少包括由所述第四信号承载的第四信息比特的部分或全部；
其中，所述第三信号为所述第一设备至少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：
接收单元，其接收来自网络设备的第一信号，所述第一信号至少包括与第三信号和/或第四信号相关的时域资源信息；
发送单元，其向所述网络设备发送第二信号，所述第二信号至少包括由所述第四信号承载的第四信息比特的部分或全部；
其中，所述第三信号为所述第一设备至少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)使用哪些时域资源发送第三信号和/或接收第四信号的问题，提高了信号收发的可靠性。

下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
第一方面的实施例
本申请实施例提供一种信号发送方法，从终端设备一侧进行说明。
图2是本申请实施例的信号发送方法的一示意图，如图2所示，该方法包括：
210，第一设备接收来自网络设备的第一信号，该第一信号至少包括与第三信号和/或第四信号相关的时域资源信息；
220，第一设备向网络设备发送第二信号，该第二信号至少包括由第四信号承载的第四信息比特的部分或全部。
在上述实施例中，第三信号为第一设备至少向第一终端设备发送的信号，第四信号为第一设备从第二终端设备接收的信号。
值得注意的是，以上附图2仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2的记载。
图3是第一设备与网络设备和终端设备的信息交互的一示意图。如图3所示，第一设备310可以接收来自网络设备320的第一信号，向第一终端设备330发送第三信号，接收来自第二终端设备340的第四信号，向网络设备320发送第二信号。可选的，如图3所示，第一设备310还可以接收来自网络设备320的第五信号。关于第一信号至第五信号的具体含义，将在后面进行说明。其中，第三信号可以发送给多于一个第一终端设备330。
在图3的示例中，以第一终端设备330和第二终端设备340为相同的终端设备为例，例如，第一终端设备330和第二终端设备340具有相同的终端标识(device ID)，但本申请不限于此，第一终端设备330和第二终端设备340也可以是不同的终端设备。
在本申请实施例中，第一设备可以是图1B所示的场景下的中间节点103，也可 以是图1C所示的场景下的辅助节点103，例如为转发器(repeater)或IAB节点或UE或中继(relay)等等，第一终端设备和第二终端设备可以是图1A至图1C所示的场景下的终端设备102，例如为标签类型物联网终端设备(A-IoT设备)，其能力远低于第一设备。
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)相关的时域资源信息，和/或承载与从第二终端设备接收的信号(第四信号)相关的时域资源信息，解决了第一设备使用哪些时域资源向第一终端设备发送信号(第三信号)和/或第一设备使用哪些时域资源接收来自第二终端设备的信号(第二信号)的问题，提高了信号收发的可靠性。
图4是第一信号至第四信号的时域资源的一示意图，如图4所示，第一信号和第四信号是第一设备接收的信号，第二信号和第三信号是第一设备发送的信号，第一信号和第二信号是第一设备与网络侧通信的信号，第三信号和第四信号是第一设备与终端设备(device)侧通信的信号。此外，图4中，矩形方块代表各信号的时域资源。关于各信号的时域资源之间的关系，将在后面进行说明。
在图4的示例中，仅示出了各信号之间的时域关系，在一些示例中，第一信号也可以调度多个第三信号或第四信号，此外，多个第四信号也可以是一个第三信号的响应，等等。
在本申请实施例中，为了方便说明，将承载第一信号的时域资源称为第一时域资源，将承载第二信号的时域资源称为第二时域资源，将承载第三信号的时域资源称为第三时域资源，将承载第四信号的时域资源称为第四时域资源。
在一些实施例中，与第一信号相关的时域资源例如为用于承载第一信号的第一时域资源；与第二信号相关的时域资源例如为用于承载第二信号的第二时域资源，或者为用于确定第二时域资源的第二参考时域资源；与第三信号相关的时域资源例如为用于承载第三信号的第三时域资源，或者为用于确定第三时域资源的第三参考时域资源；与第四信号相关的时域资源例如为用于承载第四信号的第四时域资源，或者为用于确定第四时域资源的第四参考时域资源。
在一些实施例中，与第一信号和/或第二信号和/或第三信号和/或第四信号相关的时域资源(例如第一时域资源，和/或，第二时域资源或者第二参考时域资源，和/或，第三时域资源或者第三参考时域资源，和/或，第四时域资源或者第四参考时域资源) 可以至少包括以下至少之一：
时域资源的起始；
时域资源的时域偏移(offset)；
时域资源的持续时间；
时域资源的结束；
时域资源的参考子载波间隔(reference SCS)；
时域资源的周期。
在上述实施例中，关于时域资源的起始和/或结束以及时域资源的时域偏移：
在一些可能的实现方式中，时域资源的起始和/或结束以NR系统中的帧(frame)和/或子帧(subframe)和/或时隙(slot)和/或符号(symbol)为单位；时域资源的起始和/或结束的时间偏移(time offset)，也即时域资源的时域偏移，可以由物理层信令指示和/或MAC CE指示和/或RRC信令配置，例如可以是帧偏移(frame offset)和/或子帧偏移(subframe offset)和/或时隙偏移(slot offset)和/或符号偏移(symbol offset)。
在一个例子中，时域资源的起始配置为时隙偏移(slot offset)和符号偏移(symbol offset)。第二参考时域资源和/或第三参考时域资源和/或第四参考时域资源所在的时隙为n，则第一设备在时隙n之后的第K个时隙开始发送第三信号。
在上述例子中，K的取值为大于或等于0的正整数，可以由RRC信令或MAC CE或物理层信令配置，例如，K的取值范围可以为{0，1，…，Kmax}，K的具体取值可以由RRC信令或者MAC CE或者物理层信令来指示；
在上述例子中，时隙n+K中的第S个符号开始为第二时域资源和/或第三时域资源和/或第四时域资源的开始和/或结束。例如，默认第一设备在时隙n+K内第一个符号开始为第二时域资源和/或第三时域资源和/或第四时域资源的开始和/或结束。再例如，S由RRC信令或者MAC CE或者物理层信令配置或指示，例如，S的取值范围为{0,1,…,13}，上述RRC信令或者MAC CE或者物理层信令指示S具体取值为上述取值范围中的一个。再例如，S与时域资源的持续时间联合指示，例如，通过SLIV(Start and Length Indicator Value，起始和长度指示值)方式确定S，也即，指示SLIV对应的标号或者数值，由此可以确定对应的起始符号以及持续的符号数或持续的长度。
在另一些可能的实现方式中，时域资源的起始和/或结束以绝对时间T(例如秒、毫秒、微妙等等)为单位。
在一个例子中，T为标准预先约定的默认值。
在另一个例子中，T由网络侧配置。
例如，T为网络侧基于UE上报的能力信息配置的值。例如，网络设备基于UE能力相关的表格确定T，如下面的表1所示，网络设备根据UE上报的等级(class)配置T值(ms)。
表1
再例如，T为网络侧直接配置的值。例如，T的取值范围为{T1，T2，T3，…}，网络设备指示T可以取上述取值范围中的一个值。

在上述例子中，P可以是固定值，例如协议中预先定义好，本申请不限于此，P也可以是网络侧配置的值，例如P由上述第一信号或者第五信号配置。
在上述实施例中，关于时域资源的参考子载波间隔：
在一些可能的实现方式中，时域资源的参考子载波间隔是标准预先约定的，和/或是根据预定规则确定的，和/或是由来自网络设备的信号配置的。

在上述实现方式中，第三阈值(Tmax2)至少根据device(第二终端设备)上报的capability(能力)确定，例如，该Tmax2与device晶振精度有关。通过规定Tmax2，能够保证device发送第四信号的时域资源是在device能够保证同步精度的时间范围内。该示例以第一终端设备和第二终端设备相同为例，但本申请不以此为限。此外，上述第三阈值(Tmax2)可以是配置得到的参数，也可以是协议规定好的参数。
在上述实现方式中，如果第一设备发送第三信号与接收第四信号的动作是连续的，也即，第一设备发送第三信号结束后就接收第四信号，则Tmin2和Tmax2限制的是承载第三信号的第三时域资源(或其开始或结束)与承载第四信号的第四时域资源(或其开始或结束)之间的时间间隔。例如，第一设备在发送多个第三信号后开始接收一个或多个第四信号，则Tmin1和Tmax1限制的是发送的最后一个第三信号与第一个第四信号之间的时间间隔。

在上述实现方式中，第五阈值(Tmax3)可以是协议规定好的，也可以是网络侧配置的，本申请对具体的配置方式不做限制。
根据上述实施例，通过限制第六阈值(Tmin3)，保证了第一设备能够完成接收第四信号的处理以及发送第二信号前的处理，避免接收和发送之间出现冲突。此外，通过限制第五阈值(Tmax3)，限制了第一设备发送第二信号的时延。
在上述实施例中，如果第一设备发送第二信号与接收第四信号的动作是连续的，也即，第一设备接收第四信号结束就发送第二信号，Tmin3和Tmax3限制的是承载第四信号的第四时域资源(或其起始或结束)与承载第二信号的第二时域资源(或其起始或结束)之间的时间间隔。例如第一设备在接收一个或多个第四信号后开始发送一个或多个第二信号，则Tmin3和Tmax3限制的是接收最后一个第四信号与发送第一个第二信号之间的时间间隔。
在一些实施例中，第四信号还用于响应第三信号。也即，第二终端设备在第一终端设备接收到第三信号之后发送第四信号。
在上述实施例中，一个第四信号可以用于响应一个第三信号。本申请不限于此，也可以是，大于一个第四信号用于响应一个第三信号。例如第二终端设备在一定时间 内发送多个第四信号。
根据上述实施例，由于终端设备(第一终端设备/第二终端设备)的能力较弱，无法自发发送上行信号，但是可以响应第三信号来发送信号(第四信号)，由此能够对下行command/inventory进行响应。
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。
