为便于理解本申请实施例的技术方案，对本申请的相关技术进行说明。
一、零功耗通信
零功耗通信采用能量采集和反向散射通信技术。零功耗通信网络由网络设备和零功耗终端构成。
如图2所示，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。
以下，对零功耗通信中的关键技术进行说明。
1、射频能量采集(RF Power Harvesting)
如图3所示，射频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。
2、反向散射通信(Back Scattering)
如图4所示，零功耗终端接收网络设备发送的载波信号，并对所述载波信号进行调制，加载需要发送的信息并将调制后的信号从天线辐射出去，这一信息传输过程称之为反向散射通信。反向散射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，使电子标签阻抗的大小等参数随之改变，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。在电阻负载调制中，负载并联一个电阻，该电阻基于二进制数据流的控制接通或断开，如图5所示。电阻的通断会导致电路电压的变化，因此实现幅度键控调制(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。类似地，在电容负载调制中，通过电容的通断可以实现电路谐振频率的变化，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。
可见，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)终端不主动发射信号，因此不需要复杂的射频链路，如PA、射频滤波器等；
(2)终端不需要主动产生高频信号，因此不需要高频晶振；
(3)借助反向散射通信，终端信号传输不需要消耗终端自身能量。2、射频能量采集(RF Power Harvesting)。
3、编码技术
电子标签传输的数据，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、差动编码、脉冲间隔编码(PIE)、双向空间编码(FM0)、米勒(Miller)编码利差动编码等。通俗来说，是采用不同的脉冲信号表示0和1。
在一些场景中，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，以及反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。
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，模数转换器(Analog-to-Digital Converter，ADC)等器件，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，以及反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。
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
有些场景下使用的零功耗终端也可以为有源零功耗终端，此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，以及反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。
二、蜂窝无源物联网
随着5G行业应用的增加，连接物的种类和应用场景越来越多，对通信终端的成本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，充实5G网络链接终端类型和数量，真正实现万物互联。其中无源物联网设备可以基于零功耗通信技术，如RFID技术，并在此基础上进行延伸，以适用于蜂窝物联网。
在实际网络部署中，零功耗通信技术面临的一个技术瓶颈是前向链路的覆盖距离受限，主要原因在于前向链路的通信距离受限于到达零功耗终端处的无线信号的信号强度，基于目前工艺，一般零功耗终端需要消耗10uw(微瓦)的功率以驱动低功耗电路。这意味着到达零功耗终端的信号功率至少需要为-20dBm。受限于无线电监管的要求，网络设备的发射功率一般不能太大，例如在RFID工作的ISM频段，最大发射功率为30dBm。因此，考虑到空间的无线电传播损耗，无源零功耗终端的传输距离一般在10m至几十米的范围。
半无源零功耗终端具有显著扩展通信距离的潜力，这是由于，半无源零功耗终端可以使用RF能量采集模块收集无线电波，因此可以源源不断获取无线电能量并储存于储能单元中。储能单元获得足够的能量后，可以驱动低功耗电路工作用于前向链路的信号解调以及反向链路的信号调制等操作。此时，半无源零功耗终端就等效于一个有源终端，其下行的覆盖取决于下行信号的接收机灵敏度(通常远低于RF能量采集门限)。基于目前的工艺，能量采集模块可以在接收的无线电信号强度不低于-30dBm时可以进行能量采集并将电能输入到储能单元。因此，半无源零功耗终端的前向链路的覆盖取决于RF能量采集门限(如-30dBm)，相对无源零功耗终端，接收的无线电信号强度从-20dBm放松到-30dBm，因此可以获得10dB的链路预算增益，因此可以提升多于3倍的下行覆盖。
然而，在提升前向链路覆盖的同时，半无源零功耗终端也面临充电效率下降的问题。随着接收信号强度的下降，能量采集模块可采集并储存的能量大幅降低。如，在接收信号强度为-30dBm时，也即1微瓦时，可采集并存储的能量远不及1微瓦(即能量采集效率大幅下降)。另一方面，如前所述，零功耗终端的低功耗电路可能需要消耗10uw的功率以驱动低功耗电路。
在NR系统中，当被调度进行数据传输时，发送端需要根据调度信息来确定传输块的大小(Transport block size，TBS)，进一步从数据缓存中取相应的数据进行编码、调制和物理资源的映射等处理操作。对于零功耗终端而言，如何确定TBS以保证数据的成功传输是一项亟需解决的问题。

在实际部署中，不同终端距离供能设备的距离可能不同，这就导致终端设备的能量采集效率不同，例如，随着供能信号的接收强度的下降，终端设备的能量采集模块采集并存储能量的速度下降。则对于不同的终端设备，采集驱动终端设备的芯片电路所需的功率(例如10uw)，所需的时间也是不同的。
也就是说，基于相同的供能信号进行能量采集，对于不同距离的终端设备而言，终端设备的能力采集效率不对，进而导致终端设备的储能状态不同，相应地，终端设备支持的反向散射通信时长也不同，进而影响终端设备能够传输的传输块大小。
因此，供能信号的强度正比于终端设备的能量采集能力，能力采集效率，反向散射通信时长，终端设备可以根据供能信号的强度确定目标传输块大小。具体实现和实施例一至实施例三中的实现方式类似，这里不再赘述。
应理解，所述终端设备的供能信号的强度信息也可以替换为其他等价表述，例如所述终端设备的供能信号的接收功率信息等，本申请并不限于此。
在一些实施例中，终端设备可以向网络设备上报供能信号的测量结果，例如接收强度，从而网络设备根据该供能信号的测量结果确定终端设备选择的传输块大小，进一步根据该传输块大小进行传输块的检测，能够保证终端设备和网络设备对于传输块大小的理解一致。
可选地，终端设备可以周期性地，或者事件触发型的向网络设备上报供能信号的测量结果。
在另一些实施例中，终端设备可以不向网络设备上报供能信号的测量结果，此情况下，网络设备可以盲检终端设备发送的传输块。
在又一些实施例中，终端设备可以向网络设备发送第一指示信息，所述第一指示信息用于指示所述终端设备确定的目标传输块大小信息。例如可以将该目标传输块大小信息和传输块一起发送给网络设备，也就是说，目标传输块大小信息和传输块可以承载在同一反向散射信号中发送给网络设备。
可选地，所述目标传输块大小信息可以通过上行控制信息携带。此情况下，网络设备可以根据所述上行控制信息中的第一指示信息确定目标传输块大小。
在又一些实施例中，终端设备向网络设备发送的传输块中包括传输块的起始标识信息和/或结束标识信息，其中，传输块的起始标识信息用于标识传输块的起始位置，传输块的结束标识信息用于标识传输块的结束位置。
可选地，该传输块的起始标识信息和结束标识信息可以为网络设备和终端设备约定的标识信息，分别设置在传输块的起始位置和传输块的结束位置。
此情况下，网络设备可以根据所述传输块的起始标识信息和/或结束标识信息确定目标传输块大小。
图10是终端设备根据供能信号的测量结果进行传输块大小选择的示意性图，应理解，终端设备根据供能信号的测量结果确定传输块大小时也可以结合其他参考信息，例如反向散射信号的资源配置信息，终端设备支持的反向散射通信时长信息，进一步地，在确定传输块大小后，可以从存储器中获取相应大小的数据，然后进行数据的发送。
综上所述，终端设备可以根据与终端设备通过能量采集获取能量相关的第一信息确定目标传输块大小，进一步根据该目标传输块大小进行传输块的发送，有利于保证数据的成功传输。
对应地，网络设备可以根据第一信息，第一指示信息，或者传输块的起始标识信息和/或结束标 识信息确定目标传输块大小，从而实现对终端设备发送的传输块的检测。
