Abstract

本申请实施例提供了一种上报UCI的方法、终端设备和网络设备，所述方法包括：确定用于上报第一上行控制信息UCI的第一反向散射资源；基于所述第一反向散射资源，向网络设备上报所述第一UCI。本申请提供的方法不仅能够避免UCI的上报与其他信道产生资源冲突，还能够降低UCI的传输时延。

Description

上报UCI的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及上报UCI的方法、终端设备和网络设备，
背景技术
目前，终端设备通常通过物理上行信道向网络设备上报上行控制信息(Uplink Control Information，UCI)，例如物理上行控制信道(Physical Uplink Control Channel，PUCCH)/物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。但是，通过物理上行信道上报UCI时，当该物理上行信道与较低优先级索引对应的信道在时间上重叠时，会影响较低优先级索引对应的信道的传输；当与较高优先级索引对应的信道在时间上重叠时，则会取消该物理上行信道的发送，即会取消UCI上报。此外，由于UCI的上报只能在上行资源上进行，因此，对于下行资源的占比较大的时分双工(Time Division Duplexing，TDD)帧结构，取消UCI上报会使得UCI的上报产生较大的传输时延。
因此，本领域亟需一种上报UCI的方法，以避免UCI的上报与其他信道产生冲突并降低UCI的传输时延。

应理解的是，零功耗设备可以被理解为功耗低于预设功耗的设备。例如包括无源终端，甚至还包括半无源终端等。
示例性地，零功耗设备是无线射频识别(Radio Frequency Identification，RFID)标签，它是利用无线射频信号空间耦合的方式，实现无接触的标签信息自动传输与识别的技术。RFID标签又称为“射频标签”或“电子标签”。根据供电方式的不同来划分的电子标签的类型，可以分为有源电子标签，无源电子标签和半无源电子标签。有源电子标签，又称为主动式电子标签，是指电子标签工作的能量由电池提供，电池、内存与天线一起构成有源电子标签，不同于被动射频的激活方式，在电池更换前一直通过设定频段发送信息。无源电子标签，又称为被动式电子标签，其不支持内装电池，无源电子标签接近读写器时，标签处于读写器天线辐射形成的近场范围内电子标签天线通过电磁感应产生感应电流，感应电流驱动电子标签芯片电路。芯片电路通过电子标签天线将存储在标签中的标识信息发送给读写器。半无源电子标签，又被称为半主动式电子标签，其继承了无源电子标签体积小、重量轻、价格低、使用寿命长的优点，内置的电池在没有读写器访问的时候，只为芯片内很少的电路提供电源，只有在读写器访问时，内置电池向RFID芯片供电，以增加标签的读写距离较远，提高通信的可靠性。
RFID系统是一种无线通信系统。RFID系统是由电子标签(TAG)和读写器(Reader/Writer)两部分构成。电子标签包括耦合组件及芯片，每个电子标签都有独特的电子编码，放在被测目标上以达到标记目标物体的目的。读写器不仅能够读取电子标签上的信息，而且还能够写入电子标签上的信息，同时为电子标签提供通信所需要的能量。
零功耗通信采用能量采集和反向散射通信技术。为便于理解本申请实施例的技术方案，对零功耗的相关技术进行说明。
图2为本申请提供的零功耗通信系统的示意图。
如图2所示，零功耗通信系统由网络设备和零功耗终端构成，网络设备用于向零功耗终端发送无线供能信号，下行通信信号以及接收零功耗终端的反向散射信号。一个基本的零功耗终端包含能量采集模块，反向散射通信模块以及低功耗计算模块。此外，零功耗终端还可具备一个存储器或传感器，用于存储一些基本信息(如物品标识等)或获取环境温度、环境湿度等传感数据。
零功耗通信也可称为基于零功耗终端的通信，零功耗通信的关键技术主要包括射频能量采集和反向散射通信。
1、能量采集(RF Power Harvesting)。
图3为本申请实施例提供的能量采集原理图.
如图3所示，能量采集模块可包括电容C和电阻R L，能量采集模块基于电磁感应原理实现对空间电磁波能量的采集，进而获得驱动零功耗终端工作所需的能量，例如用于驱动低功耗解调以及调制模块、传感器以及内存读取等。因此，零功耗终端无需传统电池。电磁感应原理指只要穿过闭合电路的磁通量发生变化，闭合电路中就会产生感应电流。结合本申请来说，电容C和电阻R L可用于形成闭合电路，射频能量采集模块接收到射频(RF)后，可产生感应电流并将产生的感应电流存储在电容C中，以实现对空间电磁波能量的采集。
2、反向散射通信(Back Scattering)。
图4为本申请提供的反向散射通信原理图。
如图4所示，网络设备作为发送端(TX)时，所述网络设备通过放大器(AMP)向零功耗设备发送载波。相应的，零功耗设备接收网络发送的载波后，利用能量采集模块采集的能量，驱动逻辑处理模块对需要发送的信息进行处理，并通过可变电阻将需要发送的信息加载到接收到的载波上，以得到反射信号，最后将得到的反射信号从天线辐射出去，这种信息传输过程称之为反向散射通信。相应的，网络设备作为接收端(RX)时，可通过低噪音放大器(LNA)接收零功耗设备发送的反射信号。进一步的，在一些可能的实现方式中，AMP和LNA可以各自连接有一个电压显示灯，AMP和LNA分别连接的电 压显示灯之间可设置一个应急灯。
需要说明的是，图4所示的反向散射通信原理是通过零功耗设备和网络设备说明的，实际上，任何具有反向散射通信功能的设备都可以实现反向散射通信。
反向散射通信和负载调制功能密不可分。负载调制通过对零功耗终端的振荡回路的电路参数按照数据流的节拍进行调节和控制，使零功耗设备阻抗的大小和相位随之改变，从而完成调制的过程。负载调制技术主要包括电阻负载调制和电容负载调制两种方式。
图5为本申请实施例提供的电阻负载调制的电路原理图。
如图5所示，在电阻负载调制中，电阻R L并联一个电阻R 3，电阻R L可称为负载调制电阻，电阻R L和电阻R 3的所在支路基于开关S的控制接通或断开，开关S可由二进制数据流进行控制，R L和电阻R 3的所在支路的通断会导致电路电压的变化。进一步的，电阻R L可通过电阻R 2与电感L 1并联，电感L 1用于和电感L 2形成谐振电路，基于此，R L和电阻R 3的所在支路的通断会导致电路电压的变化，进而会导致谐振电路的谐振频率的变化，最终实现幅度键控调制(ASK)，即通过调整零功耗终端的反向散射信号的幅度大小实现信号的调制与传输。进一步的，电感L 2还可用于连接至电容C 2，电容C 2可用于谐振电路的谐振频率的变化转换为天线用于发送的信号。类似地，在电容负载调制中，通过电容C 1和电阻R 3的所在支路的通断可以实现谐振电路的谐振频率的变化，实现频率键控调制(FSK)，即通过调整零功耗终端的反向散射信号的工作频率实现信号的调制与传输。
由于零功耗终端借助于负载调制的方式对来波信号进行信息调制，从而实现反向散射通信过程。因此，零功耗终端具有显著的优点：
1、终端设备不主动发射信号，通过调制来波信号实现反向散射通信。
2、终端设备不依赖传统的有源功放发射机，同时使用低功耗计算单元，极大降低硬件复杂度。
3、结合能量采集可实现免电池通信。
应当理解的是，上述终端设备可以是零功耗设备(如无源终端，甚至是半无源终端)，甚至该终端设备可以是非零功耗设备，如普通终端，但是该普通终端可以在有些情况下进行反向散射通信。
具体实现中，终端设备传输的数据可以用不同形式的代码来表示二进制的“1”和“0”。无线射频识别系统通常使用下列编码方法中的一种：反向不归零(NRZ)编码、曼彻斯特(Manchester)编码、单极性归零(Unipolar RZ)编码、差动双相(DBP)编码、米勒(Miller)编码利差动编码。通俗的说，就是用不同的脉冲信号表示0和1。
示例性地，基于零功耗终端的能量来源以及使用方式可以将零功耗终端分为如下类型：
1、无源零功耗终端。
零功耗终端不需要内装电池，零功耗终端接近网络设备(如RFID系统的读写器)时，零功耗终端处于网络设备天线辐射形成的近场范围内。因此，零功耗终端天线通过电磁感应产生感应电流，感应电流驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及后向链路的信号调制等工作。对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。
由此可以看出，无源零功耗终端无论是前向链路还是反向链路都不需要内置电池来驱动，是一种真正意义的零功耗终端。无源零功耗终端不需要电池，射频电路以及基带电路都非常简单，例如不需要低噪放(LNA)，功放(PA)，晶振，ADC等期间，因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
2、半无源零功耗终端。
半无源零功耗终端自身也不安装常规电池，但可使用RF能量采集模块采集无线电波能量，同时将采集的能量存储于一个储能单元(如电容)中。储能单元获得能量后，可以驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及后向链路的信号调制等工作。对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。
由此可以看出，半无源零功耗终端无论是前向链路还是反向链路都不需要内置电池来驱动，虽然工作中使用了电容储存的能量，但能量来源于能量采集模块采集的无线电能量，因此也是一种真正意义的零功耗终端。半无源零功耗终端继承了无源零功耗终端的诸多优点，因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
3、有源零功耗终端。
在某些场景下，使用的零功耗终端也可以为有源零功耗终端，该类终端可以内置电池。电池用于驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及后向链路的信号调制等工作。但对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。因此，这类终端的零功耗主要体现于反向链路的信号传输不需要终端自身功率，而是使用反向散射的方式。也即是说，有源零功耗终端通过内置电池向RFID芯片供电，以增加零功耗终端的读写距离，提高通信的可靠性。因此在一些对通 信距离，读取时延等方面要求相对较高的场景得以应用。
示例性地，零功耗终端可基于供能信号进行能量采集。
可选的，从供能信号载体上，所述供能信号可以是基站、智能手机、智能网关、充电站、微基站等。
可选的，从频段上，所述供能信号可以是低频、中频、高频信号等。
可选的，从波形上，所述供能信号可以是正弦波、方波、三角波、脉冲、矩形波等。
可选的，所述供能信号可以是连续波，也可以是非连续波(即允许一定的时间中断)。
可选的，所述供能信号可以是3GPP标准中规定的某一信号。例如，SRS，PUSCH、PRACH、PUCCH、PDCCH、PDSCH、PBCH等。
需要说明的是，由于上述网络设备发送的载波信号也可用于向零功耗设备提供能量，因此该载波信号也可被称为供能信号。
示例性地，零功耗终端可基于收到的触发信号进行反向散射通信。
可选的，所述触发信号可用于调度或者触发零功耗终端反向散射通信。
可选的，所述触发信号携带有网络设备的调度信息，或者，所述触发信号为所述网络设备发送的调度信令或调度信号。
可选的，从供能信号载体上，所述触发信号可以是基站、智能手机、智能网关等。
可选的，从频段上，所述触发信号可以是低频、中频、高频信号等。
可选的，从波形上，所述触发信号可以是正弦波、方波、三角波、脉冲、矩形波等。
可选的，所述触发信号可以是连续波，也可以是非连续波(即允许一定的时间中断)。
可选的，所述触发信号可以是3GPP标准中规定的某一信号。例如SRS，PUSCH、PRACH、PUCCH、PDCCH、PDSCH、PBCH等；也可能是一种新的信号。
需要说明的是，所述供能信号和所述触发信号可以是一个信号，也可以是2个独立的信号，本申请对此不作具体限定。
例如，在蜂窝网络中，由于零功耗设备没有电池供电，需要通过网络设备提供供能信号，用于零功耗设备获得能量，从而进行相应的通信过程。其中，用于供能的信号(即供能信号)和用于信息传输的信号(即触发信号)可以是两个信号，也可以是一个信号。再如，在RFID技术中，所述供能信号和所述触发信号可以是一个信号，在蜂窝无源物联网技术中，所述供能信号和所述触发信号可以是两个独立的信号。这两个信号可以不在一个频段发送。例如网络设备在某个频段持续或者间歇性的发送供能信号，零功耗设备进行能量采集，零功耗设备获得能量之后，可以进行相应的通信过程，如测量、信道/信号的接收、信道/信号的发送等。
在进行信号的发送时，零功耗设备可以是在预设资源上发送，例如可以不同用户ID或者不同用户类型可以采用不同的资源，零功耗设备也可以是基于网络设备的调度进行发送，即接收触发信号，并基于触发信号的调度进行发送。
由于零功耗设备不能产生高频信号，因此在反向链路中采用副载波调制方式或通断键控(On-Off Keying,OOK)调制方式对编码后的基带编码数据流进行调制。
图6是本申请实施例提供的副载波调制方式的示意图。
如图6所示，对于副载波调制方式，零功耗设备先产生一个低频副载波，然后将编码后的基带编码数据流在所述低频副载波上进行调制，以得到调制副载波；之后，通过负载调制的方式将所述调制副载波在高频载波上进行调制，以得到调制高频副载波。
图7是本申请实施例提供的OOK调制方式的示意图。
如图7所示，对于OOK调制方式，零功耗设备将编码后的基带编码数据流在零功耗设备接收到的信号上进行调制，以得到反射信号，并将发射信号发送给网络设备。其中，零功耗设备接收到的信号可以是高频信号或者特定的载波信号。
随着5G行业中应用需求的增加，连接物的种类和应用场景越来越多，对通信终端的价格和功耗也将有更高要求，免电池、低成本的无源物联网设备的应用成为蜂窝物联网的关键技术，其能够充实网络中的终端的类型和数量，进而能够真正实现万物互联。其中，无源物联网设备可以基于现有的零功耗设备，如无线射频识别(Radio Frequency Identification，RFID)技术，并在此基础上进行延伸，以适用于蜂窝物联网。
下面对基于物理上行信道的上行控制信息(Uplink Control Information，UCI)的上报方案进行说明。
终端设备可以通过物理上行信道向网络设备上报UCI。例如终端设备可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)向网络设备上报UCI。
作为一个示例，终端设备通过PUCCH上报UCI时，UCI可包括以下中的至少一项：混合自动重传 请求确认(Hybrid Automatic Repeat Request-ACK，HARQ-ACK)信息、HARQ非确认(NACK)信息、无线资源控制(Radio Resource Control，RRC)重配置信令、调度请求(Scheduling Request，SR)、链接恢复请求(link recovery request，LRR)、信道状态信息(Channel State Information，CSI)。可选的，网络设备可通过高层信令为终端设备配置最多4个PUCCH资源集合，其中资源集合0用于承载1～2比特UCI，资源集合1、2的负载可通过高层信令配置，而资源集合3的最大负载为1706，该数值来自于Polar编码的限制。对于PUCCH集合0(用于承载1～2比特UCI)，高层信令可配置最多32个PUCCH资源；当PUCCH资源数量不大于8时，直接根据DCI中的指示确定使用的PUCCH资源；当PUCCH资源数量大于8时，则根据控制信道单元(Control Channel Element，CCE)的索引和下行控制信息(Downlink Control Information，DCI)中的3比特指示信息确定使用的PUCCH资源。对于PUCCH集合1、2、3(承载2比特以上UCI)，高层信令可配置最多8个PUCCH资源，终端设备可根据DCI中的3比特指示信息确定使用的PUCCH资源。
作为另一个示例，终端设备通过PUSCH上报UCI时，网络设备可以针对UCI确定用于确定UCI的传输资源的偏移值，并通过调度PUSCH传输的DCI格式或高层信令将确定的偏移值指示给终端设备。可选的，在一个PUSCH中，终端设备可采用多路复用的方式向网络设备发送UCI，例如HARQ-ACK信息和/或CSI。
但是，通过物理上行信道上报UCI时，当该物理上行信道与较低优先级索引对应的信道在时间上重叠时，会影响较低优先级索引对应的信道的传输；当与较高优先级索引对应的信道在时间上重叠时，则会取消该物理上行信道的发送，即会取消UCI上报。此外，由于UCI的上报只能在上行资源上进行，因此，对于下行资源的占比较大的时分双工(Time Division Duplexing，TDD)帧结构，取消UCI上报会使得UCI上报产生较大的传输时延。
示例性地，不同优先级索引的PUCCH和/或PUSCH传输存在重叠的情况包括但不限于：
情况1：一个具有较大优先级索引的第一个PUCCH和一个具有较小优先级索引的第二个PUCCH或PUSCH。
情况2：配置了优先级索引较大的PUSCH和优先级索引较小的PUCCH。
情况3：携带有HARQ-ACK信息、仅用于响应一个PDSCH接收(没有相应的PDCCH)的具有较大优先级索引的第一个PUCCH，与以下中的任一项：携带有SR和/或CSI的、且具有较低优先级索引的第二个PUCCH；具有较低优先级索引的免调度PUSCH；没有相应PDCCH携带有SP-CSI上报信息的具有较低优先级索引的PUSCH。
情况4：具有SP-CSI上报信息而没有相应的PDCCH的一个具有较大优先级索引的PUSCH和携带SR、CSI、HARQ-ACK信息(仅响应没有相应PDCCH的PDSCH接收)中的至少一项的、且具有较小优先级索引的PUCCH。
情况5：在同一个小区上，一个具有较高优先级索引的免调度PUSCH和一个具有较低优先级索引的免授权调度PUSCH。
当优先级索引不同的两个物理上行信道在时间上存在重叠时，终端设备会处理优先级索引较低的物理上行信道的传输。例如，如果优先级索引较低的物理上行信道，在时间上与优先级索引较高的物理上行信道重叠，则终端设备会取消与优先级索引较高的物理上行信道发生重叠的优先级索引较低的物理上行信道的传输。进一步的，终端设备还可以取消与优先级索引较高的物理上行信道重叠的第一个符号之前的优先级索引较低的物理上行信道的传输。
当然，不同优先级的PUCCH传输(或PUSCH传输)和PUCCH的重复传输(或PUSCH的重复传输)在时域上也有可能会发生重叠。
例如，如果由DCI格式调度的优先级索引较大的PUCCH传输，在时间上与优先级索引较小的PUSCH传输(或PUCCH的重复传输)在时间上发生重叠，则终端设备取消与PUCCH传输重叠的PUSCH传输(或PUCCH的重复传输)。进一步的，终端设备还可以取消与PUCCH传输发生重叠的第一个符号之前的PUSCH传输(或PUCCH的重复传输)。再如，如果由DCI格式调度的优先级索引较大的PUSCH的传输，在时间上与优先级索引较小的PUCCH的重复传输在时间上发生重叠，则终端设备取消与PUSCH传输发生重叠的PUCCH的重复传输。进一步的，终端设备还可以取消与PUSCH传输发生重叠的第一个符号之前的PUCCH的重复传输。再如，如果优先级索引较低的PUCCH的重复传输(或PUSCH的重复传输)，在时间上与优先级索引较高的PUCCH传输(或PUSCH传输)在时间上发生重叠，则终端设备取消与优先级索引较高的PUCCH传输(或PUSCH传输)发生重叠的PUCCH的重复传输(或PUSCH的重复传输)。进一步的，终端设备还可以取消与优先级索引较高的PUCCH传输(或PUSCH传输)发生重叠第一个符号之前的优先级索引较低的PUCCH的重复传输(或PUSCH的重复传输)。
综上所述，基于物理上行信道的UCI上报，例如基于PUCCH和/或PUSCH的UCI上报，会与其他信道产生冲突问题，且取消UCI上报会使得UCI上报有可能产生较大的时延。有鉴于此，本申请实施例提供了一种上报UCI的方法、终端设备和网络设备，能够避免会与其他信道产生冲突并降低传输时延。
图8是本申请实施例提供的上报UCI的方法200的示意性流程图。所述方法200可以由终端设备执行。应当理解，终端设备可以是零功耗设备，也可以是支持反向散射通信方式的终端设备，即不要求通过能量采集方式获得能量的终端设备，例如加载或集成有反向散射通信模块的传统NR终端，本申请对此不作具体限定。例如，所述方法200可以由如图1所示的终端设备120执行，再如，所述方法200可以由零功耗设备120执行。
如图8所示，所述方法200可包括：
S210，终端设备确定用于上报第一上行控制信息UCI的第一反向散射资源；
S220，所述终端设备基于所述第一反向散射资源，向网络设备上报所述第一UCI。
示例性地，终端设备确定所述第一反向散射资源后，基于所述第一反向散射资源，以反向散射的通信方式向所述网络设备上报所述第一UCI。例如，具有反向散射通信能力的终端设备在所述第一反向散射资源，向网络设备上报所述第一UCI。
本实施例中，通过引入用于上报第一UCI的第一反向散射资源，并基于所述第一反向散射资源，向网络设备上报所述第一UCI，一方面，由于所述第一反向散射资源可以不受上行资源的限制，相当于，所述第一反向散射资源可以是用于物理信道的上行资源或下行资源，即终端设备可以在上行资源或者下行资源上向网络设备上报所述第一UCI，降低了所述第一UCI的传输时延；另一方面，所述第一UCI基于所述第一反向散射资源进行上报时，可以将其他信道作为用于反向散射的载波，因此，终端设备基于所述第一反向散射资源上报所述第一UCI时，能够更好的与其他信道兼容，例如，即便所述第一反向散射资源与其他物理上行信道冲突，终端设备仍然可以基于所述第一反向散射资源向网络设备上报所述第一UCI，相当于，能够使得所述第一UCI的传输资源和其他信道实现资源共享，不仅能够避免由于所述第一UCI的上报与其他信道产生资源冲突所导致的所述第一UCI的传输取消的问题，还能够降低所述第一UCI的传输时延。
在一些实施例中，所述方法200还可包括：
终端设备接收所述网络设备发送的第一指示信息，所述第一指示信息用于指示所述第一反向散射资源。
示例性地，终端设备通过网络设备发送的第一指示信息确定所述第一反向散射资源。
在一些实施例中，所述第一指示信息用于指示以下中的至少一项：所述第一反向散射资源的起始时间、所述第一反向散射资源的持续时间、所述第一反向散射资源的频域位置。
示例性地，所述第一指示信息包括至少一个字段，所述至少一个字段携带的信息用于指示所述第一反向散射资源的起始时间和/或所述第一反向散射资源的持续时间。
在一些实施例中，所述第一指示信息通过第一资源配置索引指示以下中的至少一项：所述第一反向散射资源的起始时间、所述第一反向散射资源的持续时间、所述第一反向散射资源的频域位置。

如图9中的(b)所示，假设网络设备发送的第一指示信息用于指示所述第一反向散射资源的起始时间为第6个基本时间单元的起始位置，且所述第一反向散射资源的持续时间为两个基本时间单元。此外，假设所述第一UCI包括对一个PDSCH(例如占据两个基本时间单元)的HARQ-ACK反馈，且第一时长包括两个基本时间单元，则所述一个PDSCH的结束位置之后间隔第一时长的位置也同样为第6个基本时间单元的起始位置。基于此，终端设备可基于所述第一指示信息、一个PDSCH的结束位置和第一时长，确定所述第一反向散射资源的起始时间；即，由于第一指示信息指示的所述第一反向散射资源的起始时间、以及所述一个PDSCH的结束位置之后间隔第一时长的位置均为第6个基本时间单元的起始位置，因此，所述第一反向散射资源的起始时间为第6个基本时间单元的起始位置，即所述第一反向散射资源包括两个用于下行传输的基本时间单元。
当然，在其他可替代实施例中，所述第一指示信息指示的所述第一反向散射资源的起始时间和所述一个PDSCH的结束位置之后间隔第一时长的位置不相同时，可以将在时域上靠前或靠后的位置确定为所述第一反向散射资源的起始时间，也可以在所述第一指示信息指示的所述第一反向散射资源的起始时 间和所述一个PDSCH的结束位置之后间隔第一时长的位置中，随机选择一个位置作为所述第一反向散射资源的起始时间。或者，所述第一指示信息未指示所述第一反向散射资源的起始时间时，则根据所述一个PDSCH的结束位置和第一时长，确定所述第一反向散射资源的起始时间。或者，所述第一指示信息可以通过指示所述第一反向散射资源的起始时间为相对所述一个PDSCH的结束位置间隔第一时长的位置，本申请实施例对此不作具体限定。
如图9中的(c)所示，假设网络设备发送的第一指示信息用于指示所述第一反向散射资源的起始时间为第9个基本时间单元的起始位置，且所述第一反向散射资源的持续时间为两个基本时间单元。此外，假设所述第一UCI包括对一个PDSCH(例如占据3个基本时间单元)的HARQ-ACK反馈，且第一时长包括两个基本时间单元，则所述一个PDSCH的结束位置之后间隔第一时长的位置也同样为第9个基本时间单元的起始位置。基于此，终端设备可基于所述第一指示信息、一个PDSCH的结束位置和第一时长，确定所述第一反向散射资源的起始时间；即，由于第一指示信息指示的所述第一反向散射资源的起始时间、以及所述一个PDSCH的结束位置之后间隔第一时长的位置均为第9个基本时间单元的起始位置，因此，所述第一反向散射资源的起始时间为第9个基本时间单元的起始位置，即所述第一反向散射资源包括两个用于上行传输的基本时间单元。
当然，在其他可替代实施例中，所述第一指示信息指示的所述第一反向散射资源的起始时间和所述一个PDSCH的结束位置之后间隔第一时长的位置不相同时，可以将在时域上靠前或靠后的位置确定为所述第一反向散射资源的起始时间，也可以在所述第一指示信息指示的所述第一反向散射资源的起始时间和所述一个PDSCH的结束位置之后间隔第一时长的位置中，随机选择一个位置作为所述第一反向散射资源的起始时间，本申请实施例对此不作具体限定。

例如，在其他可替代实施例中，还可以通过指示时域资源集合中用于反向散射通信的资源的起始时域位置、用于反向散射通信的资源的时长以及周期，确定时域资源集合中用于反向散射通信的资源。例如，时域资源集合中用于反向散射通信的资源为周期性资源时，可以通过指示时域资源集合中用于反向散射通信的资源的起始时域位置、用于反向散射通信的资源的时长以及周期的方式，来指示时域资源集合中用于反向散射通信的资源。例如，时域资源集合中用于反向散射通信的资源为周期性资源时，针对每一个资源图样，网络设备可以向终端设备指示：时域资源集合中用于反向散射通信的资源的起始时域位置为第2个资源单元的起始位置；用于反向散射通信的资源的时长为一个资源单元、或一个资源单元的一半或三分之一；以及用于反向散射通信的资源的周期。
再如，在其他可替代实施例中，还可以通过指示时域资源集合中用于反向散射通信的资源的起始位置和结束位置。例如，时域资源集合中用于反向散射通信的资源不为周期性资源时，可以通过指示时域资源集合中用于反向散射通信的资源的起始位置和结束位置，来指示时域资源集合中用于反向散射通信的资源。例如，时域资源集合中用于反向散射通信的资源不为周期性资源时，针对每一个资源图样，网络设备可以向终端设备指示：用于反向散射通信的资源的起始位置为第一个资源单元，用于反向散射通信的结束位置为第三个资源单元。
