如图1所示，本申请实施例提供的无线通信系统100可包括终端设备101以及网络设 备102。
应理解，本申请实施例提供的无线通信系统100，即可适用于低频场景(sub 6G)，也适用于高频场景(above6G)。本申请实施例提供的无线通信系统100的应用场景包括但不限于全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(new radio，NR)通信系统等。
以上所示终端设备101可以是用户设备(user equipment，UE)、终端(terminal)、移动台(mobile station，MS)、移动终端(mobile terminal)等设备，该终端设备101能够与一个或多个通信系统的一个或多个网络设备进行通信，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。举例来说，本申请实施例中的终端设备101可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，终端设备101可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。终端设备101也可以是具有通信模块的通信芯片。
另外，在未来工业场景中，终端设备101可包括未来工业场景中的用户设备，如执行器/传感器(actuator/sensor，A/S)。终端设备101可包括可编程逻辑控制器(programablelogiccontroller，PLC)，PLC作为一个逻辑功能单元、或者一个物理控制实体，用于实现具体的逻辑控制功能，所控制的功能包括通信资源调度、计算资源调度、指令调度、用户调度、作业控制等，可用于进行一个或多个用户设备的控制。例如，PLC可与未来工业场景中的网络设备进行无线通信，如接收该网络设备的控制信息，另外PLC可与未来工业场景中的一个或多个用户设备进行有线通信和/或无线通信，如收集该一个或多个用户设备需要发送的上行数据，并将该上行数据发送至网络设备。应理解，本申请所述的有线通信方式，包括但不限于通过光纤通信接口(如，以太网接口)或电信号通信接口进行数据或信息的传输。

应理解，本申请所述无线通信系统可包括未来工业场景，如未来工业4.0场景。
例如图2所示，在未来工业场景中，PLC可以位于网络设备103一侧，如PLC可以是网络设备103的组成部分，网络设备103可分别与多个无线用户设备(如A/S)104之间通过空口协议进行通信，或者，PLC可以与网络设备103通过有线或无线方式进行通信。在进行上行和/或下行数据调度时，网络设备103可分别向多个无线用户设备104发送控制信息，通过控制信息分别调度多个无线用户设备104的上行和/或下行数据。在实现中，该多个无线用户设备104的业务模式可以具有周期性特点，例如在某个循环周期(cycle time， CT)内，网络设备103下发执行指令(如DCI)，多个无线用户设备104执行该执行指令以后，可在CT内通过固定的时域资源进行上行数据传输。
在如图2所示场景中，可在网络设备103与多个无线用户设备104中的全部或部分无线用户设备104之间执行本申请实施例提供的传输资源指示方法，此时，每个无线用户设备104均可作为如图1所示终端设备101，网络设备103作为网络设备102。
又如图3所示，当PLC位于网络设备103一侧时，网络设备103可与用户设备105之间通过空口协议进行通信，用户设备105可基于有线通信接口，或基于无线链路，如侧行链路(sidelink)，与多个用户设备106进行通信。在进行上行和/或下行数据调度时，网络设备103可向用户设备105发送控制信息以调度上行和/或下行数据，用户设备105可通过有线通信接口收集多个用户设备106的上行数据，并根据控制信息的调度进行上行数据发送。在此场景下，多个用户设备106可不直接与网络设备103进行无线连接。
在如图3所示场景中，可在网络设备103与用户设备105之间执行本申请实施例提供的传输资源指示方法，此时，用户设备105可作为如图1所示终端设备101，网络设备103作为网络设备102。
又如图4所示，PLC可位于终端侧，此时，网络设备103可与PLC之间通过空口协议进行通信，PLC可基于有线通信接口与多个用户设备104进行通信。在进行上行和/或下行数据调度时，网络设备103可向PLC发送控制信息以调度上行和/或下行数据，PLC可通过有线通信接口收集多个用户设备104的上行数据，并根据控制信息的调度进行上行数据发送。在此场景下，多个用户设备104可不直接与网络设备103进行无线连接。
在如图4所示场景中，可在网络设备103与PLC之间执行本申请实施例提供的传输资源指示方法，此时，PLC可作为如图1所示终端设备101，网络设备103作为网络设备102。
再如图5所示，当PLC位于终端侧时，PLC可通过中继用户设备105与多个用户设备104进行通信，其中，PLC与中继用户设备105之间可通过sidelink进行通信，或者，PLC与中继用户设备105之间可通过有线通信接口进行通信，中继用户设备105与多个用户设备104之间可通过有线通信接口进行通信。
在如图5所示场景中，可在网络设备103与PLC之间执行本申请实施例提供的传输资源指示方法，此时，PLC可作为如图1所示终端设备101，网络设备103作为网络设备102。
下面结合图6，以如图1所示的无线通信系统为例，说明本申请实施例提供的传输资源指示方法。该方法可包括以下步骤：
S101：网络设备102确定第一信息，所述第一信息用于指示第一参考点，所以第一参考点用于确定传输资源的时域位置，所述传输资源用于网络设备102与终端设备101之间进行数据传输；
S102：网络设备102向终端设备101发送第一信息；
S103：终端设备101接收第一信息；
S104：终端设备101根据该第一参考点确定该传输资源的时域位置。
采用以上流程所示方法，本申请实施例可由网络设备102向终端设备101指示第一参考点，并由终端设备101根据该第一参考点确定传输资源的时域位置，因此根据该方法可实现传输资源的灵活指示。
在本申请实施例中，所述传输资源可用于网络设备102与终端设备101之间进行数据传输。具体的，传输资源可用于传输网络设备102向终端设备101发送的下行数据，例如， 网络设备102通过该传输资源发送下行数据，下行数据承载在物理下行共享信道(pysical downlink shared channel，PDSCH)上。网络设备101可通过控制信息调度该下行数据。另外，传输资源可用于传输终端设备101向网络设备102发送的上行数据，例如，终端设备101通过该传输资源发送上行数据，上行数据承载在物理上行共享信道(pysical uplink shared channel，PUSCH)上。网络设备101可通过控制信息调度该上行数据。
在实施中，网络设备102可通过第一信息，以显式指示或隐式指示的方式指示该第一参考点。其中，显示方式是指，第一信息可携带第一参考点的信息(如第一参考点的时域位置)，根据该信息可确定第一参考点。隐式指示是指，第一信息可携带与第一参考点有关的信息，这些信息并不直接指示第一参考点的信息，但终端设备101可根据这些信息确定出第一参考点，如，这些信息与第一参考点之间存在对应关系，从而终端设备101可根据该对应关系确定出第一参考点，或者，这些信息能够用于推导出第一参考点，从而终端设备101可根据这些信息确定出第一参考点。第一信息可以通过无线资源控制协议(Radio Resource Control,RRC)消息、媒体接入控制单元(Media access control-control element,MAC-CE)消息或者DCI等中的一个或者多个承载。或者第一信息可以通过协议预定义或预配置等方式发送。
本申请所涉及的第一参考点的数量可以为一个或多个。下面具体介绍本申请实施例中通过第一信息指示第一参考点的方法：
方法一、第一信息包括第一参考点在第一周期中的位置的信息。网络设备102可向终端设备101指示第一参考点在第一周期中的位置，从而终端设备101可根据第一周期和所述位置，确定第一参考点的时域位置。
其中，一种可能的实施方式中，第一参考点在第一周期中的位置的信息可以包括第一参考点与第一周期的起始位置之间的偏移量(offset)，该第一周期的起始位置可以是由网络设备102配置、由协议预定义或预先设置的。
应理解，本申请所述由网络设备102配置，是指由网络设备102通过信令(如高层信令或DCI等)将网络设备102所配置的信息和/或数据指示终端设备101，终端设备101可根据该信令获知该信息和/或数据。由协议定义或约定，是指将与某操作有关的信息和/或数据写入协议(如空口协议)，在基于该协议执行该操作时，按照协议写入的信息和/或数据执行，或者，采用协议中写入的信息和/或数据。预先设置或预配置，是在装置出厂或调试过程中将信息和/或数据预先进行配置，在执行相关操作时直接采用该信息和/或数据。这里所述的信息和/或数据，包括但不限于网络设备102和终端设备101各自进行配置所需的配置信息或者配置参数，以及网络设备102和终端设备101各自执行本申请所涉及的操作时所需的信息或参数等等。
例如图7所示，若第一周期的长度为10毫秒(ms)，第一周期的起始位置为第0个时间单位，第一周期的起始位置如图中箭头所示，第一参考点的位置如图中圆圈所示，第一信息可包含第一周期中第一参考点与该起始位置之间的偏移量X，如X为5个时间单位。终端设备102可根据第一周期的起始位置和偏移量X，确定第一参考点位于第5个时间单位。
应理解，以上X可以是由网络设备102配置并指示给终端设备101的，或者可以是通过协议定义或预配置的数值。
或者，在另一种可能的实施方式中，第一参考点在第一周期中的位置的信息可以包括 第一参考点在第一周期中所处的时间单位的信息。仍以图7所示第一参考点为例，第一参考点在第一周期中的位置的信息可包括第一参考点所在的时间单位的编号，如该编号为5。
以上所涉及的时间单位，可包括时隙(slot)、符号(symbol)、绝对时间长度或者其他时间单位。网络设备102可配置并向终端设备101指示该时间单位，或者，可通过协议定义或预配置的方式设定该时间单位。
这里的绝对时间长度，是指N毫秒或M微秒(μs)等，M、N均为整数，是指长度固定的一段时间，如，该绝对时间长度为20μs或50μs。
其他时间单位，可以是根据网络设备102与终端设备101之间PDCCH的子载波间隔(subcarrier spacing，SCS)、PDSCH的SCS或者PUSCH的SCS中的一个或多个子载波间隔确定的时间长度，如，该其他时间单位的长度可以是以上SCS中最小、最大或者次大的SCS下的m0个时隙或符号的长度，m0为整数。网络设备102可向终端设备101指示根据哪个SCS确定该其他时间单位的长度，或者，可预先设定通过哪个SCS确定该其他时间单位的长度。例如，当PDCCH的SCS以及PDSCH的SCS分别为15千赫兹(KHz)和30KHz时，若该其他单位的长度为PDCCH的SCS的1个符号的长度，则该其他单位的长度为1/14ms。或者，其他时间单位的长度可以是与第一周期相关的时间长度，如，第一周期的四分之一。在一种可能的实现方式中，以上所涉及的第一周期可包括半静态调度(semi-persistent scheduling)的周期。在实施中，可由网络设备102向终端设备101配置以上所涉及的半静态调度的周期。例如，网络设备102可通过配置信息，如无线资源控制层(radio resource controller，RRC)消息、介质访问控制(media access control，MAC)层控制单元(control element，CE)或者DCI中的一种，向终端设备101指示该半静态调度周期的长度，和/或半静态调度周期的起始位置。
在另一种可能的实现方式中，第一周期可以包括第一类业务的周期，该第一类业务可包括周期性的上行和/或下行数据传输。这里所涉及的第一类业务，可包括网络设备102向终端设备101配置了CT的业务，终端设备101根据该CT向网络设备102进行周期性的上行和/或下行数据传输。以上第一信息可以包括第一参考点位于CT内的位置，终端设备101可根据第一参考点在CT内的位置，确定第一参考点的时域位置。其中，网络设备102可通过RRC消息向终端设备101配置该CT的长度和起始位置。
在另一种可能的实现方式中，第一周期可以包括第一参考点周期。例如，多个第一参考点出现的周期为10ms，第一信息可包含该周期。或者，第一参考点的周期的长度可以是半静态调度周期(或CT周期)的2 g分之一或2 h倍，其中，g、h均为正整数。
网络设备102可向终端设备101指示将以上第一周期作为第一参考点的周期。或者，可通过协议定义或预配置的方式，令网络设备102和/或终端设备101将以上第一周期作为第一参考点的周期。
另外，若第一参考点的数量为一个，若第一信息包括第一参考点在半静态调度周期中的时域位置的信息，终端设备101可将该第一信息所在的半静态调度周期中，第一信息指示的时域位置作为第一参考点的时域位置；或者，终端设备101可将时域位置在该半静态调度周期之前或之后的第n个半静态调度周期中，第一信息指示的时域位置作为第一参考点的时域位置，n的取值可以由网络设备102通过第一信息或者其他信令指示，也可以由协议定义或者通过预配置的方式确定，n为正整数。
若第一参考点的数量为一个，若第一信息包括第一参考点在第一类业务的周期中的时 域位置的信息，终端设备101可将该第一信息所在的第一类业务的周期中，第一信息指示的时域位置作为第一参考点的时域位置；或者，终端设备101可将时域位置在该第一类业务的周期之前或之后的第m个第一类业务的周期中，第一信息指示的时域位置作为第一参考点的时域位置，m的取值可以由网络设备102通过第一信息或者其他信令指示，也可以由协议定义或者通过预配置的方式确定，m为正整数。方式二、第一信息包括第一参考点在第一周期中的位置的信息以及第一的周期信息。网络设备102可向终端设备101指示第一参考点在第一周期中的位置的信息以及第一周期信息，从而终端设备101可根据该位置信息以及第一周期的信息，确定第一参考点的时域位置。该确定的第一参考点的时域位置，可以包括在每个周期内的第一参考点的时域位置。该确定的第一参考点的时域位置可以包括多个一参考点的时域位置。
以第一周期为第一参考点的周期为例进行说明。如图8所示，若多个周期性出现的第一参考点的时域位置如图中圆圈所示，则第一信息可包括任意一个第一参考点(如第一个第一参考点)的位置的信息以及第一参考点周期的信息。其中，第一参考点的位置信息，可通过第一参考点所在系统帧、时隙、符号或者子帧中任意一个的编号表示，也可通过绝对时间，或者第一参考点在第一周期中所处的位置表示。
在通过第一参考点在第一周期中所处的位置表示第一参考点的时域位置时，第一信息可包括第一参考点与第一周期的起始位置之间的偏移量和/或第一参考点在第一周期中所处的时间单位，其具体方法可参照方法一中的描述。
应理解，对于网络设备102在发送第一信息之前已经配置了半静态调度周期的情况，可以参照上述第一参考点的周期的方案。比如把第一周期中第一参考点的周期的长度，替换成半静态调度周期的长度。或者说，第一参考点的周期的长度，可以与网络设备102在发送第一信息之前已经配置的半静态调度周期的长度相同。对于网络设备102在发送第一信息之前已经配置了CT周期的情况，可以参照上述第一参考点的周期的方案。比如把第一周期中第一参考点的周期的长度，替换成CT周期的长度。或者说，第一参考点的周期的长度，可以与网络设备102在发送第一信息之前已经配置的CT周期的长度相同。
方式三、第一信息包括第二参考点的时域位置的信息，所述第二参考点与第一参考点之间在时域上具有偏移量。其中，第二参考点的时域位置，可通过第二参考点所在系统帧、时隙、符号或者子帧中任意一个的编号表示，也可通过绝对时间，或者第二参考点在第二周期中的时域位置表示。这里第二周期，可以是半静态调度的周期、第一类业务的周期或者第二参考点的周期，以半静态调度周期为例，第一信息可包括第二参考点的时域位置在半静态调度周期中的时域位置。另外，第一信息还可包括第二周期的信息，如第二周期的长度和/或第二周期的时域位置。示例性的，第二参考点的周期的长度可以与第一参考点的周期的长度相同。
在通过第二参考点在第二周期中的时域位置表示该第二参考点的时域位置时，第一信息可包括第二参考点与第二周期的起始位置之间的偏移量和/或第二参考点在第二周期中所处的时间单位，具体方法可参照方法一中表示第一参考点在第一周期中的位置时的方法。
示例性的，以上第二参考点与第一参考点之间在时域上具有的偏移量，可以是网络设备102配置的值，具体的，第一信息可包括第二参考点的时域位置与第一参考点的时域位置之间的偏移量。或者，该偏移量可以是通过协议定义或预配置的方式设置的。或者，该偏移量根据终端设备101所上报的能力参数确定，终端设备101进行能力上报之后，终端 设备101和网络设备102都知道该值。又或者，该偏移量和具体的业务类型相关，例如终端设备101从预定义的位置获取的配置参数，所述预定义的位置包括内存、磁盘，核心网，配置服务器，或者其他可以与网络设备通信的实体。应理解，以上偏移量可通过时间单位表示，例如，该偏移量为y个时间单位，y为整数，时间单位的确定方法参照前述。
如图9所示，若第二参考点的时域位置(如图中箭头所示)表示为位置A1，第二参考点与第一参考点之间在时域上的偏移量为5个时间单位，则第一参考点(如图中圆圈所示)的时域位置B1可表示为B1＝A1+5个时间单位。
方式四、网络设备102可向终端设备101发送第二信息，该第二信息用于指示S101所涉及的传输资源。具体的，第二信息可以是用于调度上行和/或下行数据的控制信息，如DCI，该DCI用于指示网络设备102与终端设备101之间进行上行和/或下行数据传输时的传输资源，则第一信息可包括第一参考点的时域位置与第二信息的时域位置之间的偏移量。在本申请实施例中，第一信息以及第二信息可以是同一个控制信息，如DCI。
应理解，这里第二信息的时域位置，可以包括第二信息所占用的时隙、符号或者子帧的编号，如DCI所占用的第一个时隙/最后一个时隙的编号。该时域位置也可通过时间单位表示，如，第二信息的时域位置可通过其在第一周期中所处的时间单位表示。具体的，第二信息可以是动态调度下的控制信息，也可以是半静态调度下的控制信息。
示例性的，以上第一参考点的时域位置与第二信息的时域位置之间的偏移量，可以是网络设备102配置的值，或者，该偏移量可以是通过协议定义或预配置的方式确定的。具体的，第一信息可包括第二信息的时域位置与第一参考点的时域位置之间的偏移量。应理解，以上偏移量可通过时间单位表示，例如，该偏移量为y个时间单位，y为整数，时间单位的确定方法参照前述。
以半静态调度方式为例，如图10所示，若网络设备102向终端设备101发送的第二信息(如图中箭头所示)的时域位置表示为位置A2，第二信息的时域位置与第一参考点之间在时域上的偏移量为5个时间单位，则与第二信息相邻的第一参考点(如图中圆圈所示)的时域位置B2可表示为B2＝A2+5个时间单位。后续周期性出现的第一参考点的时域位置，可根据位置B2以及第一参考点的周期确定。
方式五、通过协议定义或预配置的方式设置多组搜索空间(search space，SS)和/或控制资源集合(control resource set，CORESET)配置，每组配置中，搜索空间和/或控制资源集合与第一参考点的时域位置对应，网络设备102可通过搜索空间或控制资源集合确定传输第二信息的资源，并通过该资源传输第二信息，从而终端设备可根据传输该第二信息的资源以及上述配置，确定第一参考点。
例如，可以设置如表一所示搜索空间和/或控制资源集合与第一参考点的时域位置对应关系表，可见，搜索空间S1与第1组第一参考点对应，控制资源集合C1与第2组第一参考点对应，另外，搜索空间S2以及控制资源集合C2以及第3组第一参考点之间两两对应。
搜索空间 控制资源集合 第一参考点
搜索空间S1 / 第1组第一参考点
/ 控制资源集合C1 第2组第一参考点
搜索空间S2 控制资源集合C2 第3组第一参考点
…… …… ……
表一
在实施中，若网络设备102向终端设备101指示第1组第一参考点，则网络设备102可根据该搜索空间S1确定传输第二信息的资源，并通过该资源传输第二信息，终端设备101可在接收第二信息后，若确定传输该第二信息的资源根据搜索空间S1确定，则可根据表一确定第一参考点为第1组第一参考点，其中，第1组第一参考点的时域位置可以由网络设备102通过第二信息或另行通过信令指示，或者由协议定义，或者通过预配置的方式确定。若网络设备102向终端设备101指示第2组第一参考点，则网络设备102可根据该控制资源集合C1确定传输第二信息的资源，终端设备101可在接收第二信息后，若确定传输该第二信息的资源根据控制资源集合C1确定，则可根据表一确定第一参考点为第2组第一参考点，其中，第2组第一参考点的时域位置可以由网络设备102通过第二信息或另行通过信令指示，或者由协议定义，或者通过预配置的方式确定。另外，若网络设备102向终端设备101指示第3组第一参考点，则网络设备102可根据该搜索空间S2确定传输第二信息的资源，并通过该资源传输第二信息，终端设备101可在接收第二信息后，若确定传输该第二信息的资源根据搜索空间S2确定，则可根据表一确定第一参考点为第3组第一参考点；或者，网络设备102可根据该控制资源集合C2确定传输第二信息的资源，终端设备101可在接收第二信息后，若确定传输该第二信息的资源根据控制资源集合C2确定，则可根据表一确定第一参考点为第3组第一参考点。其中，第3组第一参考点的时域位置可以由网络设备102通过第二信息或另行通过信令指示，或者由协议定义，或者通过预配置的方式确定。
当第一参考点的数量为一个时，网络设备102可以在第一信息中携带第一参考点的时域位置的信息，如，第一信息可包括第一参考点所在系统帧、时隙、符号或者子帧中任意一个的编号。或者，网络设备102通过其他信息(如RRC消息)指示了多个第一参考点，或者，通过协议定义或预配置的方式确定了多个第一参考点，此后，网络设备102通过该第一信息具体指示其中的一个第一参考点用于确定传输资源的时域位置，如该第一信息与该一个第一参考点之间具有对应关系。应理解，若第一参考点的数量为一个，网络设备102可通过多个不同的第一信息，分别指示多个第一参考点。
可选的，若第一参考点的数量为多个，网络设备102可在向终端设备101发送的第二信息中携带指示信息，该指示信息用于指示终端设备101根据时域位置位于该第二信息的时域位置之前或之后的第x个第一参考点确定该第二信息调度的上行和/或下行数据的传输资源的时域位置，x为非零整数。示例性的，第二信息中可通过1个或多个比特位表示x，当x的符号为正(或负)时表示根据时域位置位于该第二信息的时域位置之后的第x个第一参考点确定传输资源的时域位置，当x的符号为负(或正)时表示根据时域位置位于该第二信息的时域位置之前的第x个第一参考点确定传输资源的时域位置。
如图11所示，若网络设备102通过第一信息指示了多个第一参考点(如图中圆圈所示)，且网络设备102发送的第二信息的时域位置如图中箭头所示，当第二信息中携带表示x＝1的信息时，表示根据第二信息的时域位置之后的第1个第一参考点确定传输资源的时域位置。当第二信息中携带表示x＝-1的信息时，表示根据第二信息的时域位置之前的第1个第一参考点确定传输资源的时域位置。
另外，该指示信息可用于指示终端设备101根据时域位置位于该第二信息的时域位置之前或之后的第一参考点，确定该传输资源的时域位置，根据该指示信息，终端设备101可根据该第二信息的时域位置之前或之后的第x个第一参考点，确定该传输资源的时域位 置，此时x的取值通过协议定义，或者通过预配置的方式确定。例如，比特位被配置为0(或者1)时，表示终端设备101根据第二信息之前的第一参考点确定该传输资源的时域位置，当比特位被配置为1(或者0)时，表示终端设备101根据第二信息之后的第一参考点确定该传输资源的时域位置。
在第一参考点的数量为多个，且终端设备101接收到网络设备102发送的第二信息的情况下，终端设备101确定该第二信息调度的上行和/或下行数据的传输资源的时域位置的方式可包括以下几种：
方式一、某一个第一参考点的时域位置与该第二信息的时域位置之间的偏移量属于特定范围，则根据该第一参考点确定该传输资源的时域位置。该特定范围可以是预设的时间窗口，预设的时间窗口的长度可以由网络设备102配置，或者由协议定义或通过预配置的方式确定，或者，预设的时间窗口的长度可以为第一周期的长度。应理解，该第一参考点的时域位置可位于第二信息的时域位置之前或之后。
如图12所示，当某个第一参考点的时域位置属于以第二信息的时域位置为中心的特定范围内时，可根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源的时域位置。另外，该第二信息的时域位置也可以不位于特定范围的中心位置，如，特定范围可包括第二信息的时域位置之前的一段时域区间offsetA以及第二信息的时域位置之后的一段时域区间offsetB。可选的，offsetA的长度可以等于或不等于offsetB的长度。
又如图13所示，当第二信息的时域位置属于以某个第一参考点的时域位置为中心的特定范围内时，可根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源的时域位置。另外，该第一参考点的时域位置也可以不位于特定范围的中心位置，如，特定范围可包括该第一参考点的时域位置之前的一段时域区间offsetC以及该第一参考点的时域位置之后的一段时域区间offsetD。其中，offsetC的长度可以等于或不等于offsetD的长度。
方法二、某一个第一参考点的时域位置与该第二信息的时域位置之间的偏移量小于其他任一第一参考点的时域位置与该第二信息的时域位置之间的偏移量，即该第一参考点为时域位置与第二信息的时域位置最近的第一参考点，则根据该与第二信息的时域位置最近的第一参考点确定该传输资源的时域位置。应理解，该与第二信息的时域位置最近的第一参考点的时域位置可位于第二信息的时域位置之前或之后。
如图14所示，若该第二信息的时域位置(如图中箭头位置所示)为第n个slot，且在第n+K个slot存在最邻近的第一参考点(如图中实心圆位置所示)，则终端设备101可根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源。
方法三、若第一信息指示了多个第二参考点，若该第二信息的时域位置位于任意一个第二参考点的时域位置以及根据该第二参考点确定的第一参考点的时域位置之间，则根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源的时域位置；若该第二信息的时域位置位于任意一个第一参考点的时域位置以及该第一参考点的时域位置之后的第一个第二参考点的时域位置之间，则根据该第一参考点的时域位置之后的第一个第一参考点确定该第二信息调度的上行和/或下行数据的传输资源的时域位置。
如图15中的(a)所示，若该第二信息的时域位置(如图15中的(a)中箭头位置所示)位于第二参考点q1以及第一参考点q2(如图15中的(a)中实心圆位置所示)之间，则终端设备101可根据第一参考点q2确定该第二信息调度的上行和/或下行数据的传输资 源。
又如图15中的(b)所示，若该第二信息的时域位置(如图15中的(b)中箭头位置所示)位于第一参考点q3(如图15中的(b)中圆圈位置所示)与第二参考点q4之间，则终端设备101可根据第一参考点q5(如图15中的(b)中实心圆位置所示)确定该第二信息调度的上行和/或下行数据的传输资源。示例性的，第一参考点q5是根据第二参考点q4确定的，其具体方法可参照本申请实施例部分的描述。
示例性的，网络设备102向终端设备101发送第三信息，可用于指示终端设备101确定根据本申请实施例提供的方法确定传输资源的时域位置，即用于终端设备101确定根据第一参考点确定传输资源的时域位置。具体的，可在第二信息中携带第三信息，如，第二信息中某比特位被配置为1(或0)，该比特位可用于表示由终端设备101根据第一参考点确定传输资源的时域位置。
此外，网络设备102可采用无线网络临时标识(radio network temporary identifier，RNTI)加扰第二信息，并将被加扰的第二信息发送至终端设备101，终端设备101接收被加扰的第二信息，并在根据该RNTI确定第二信息后，即确定根据第一参考点确定传输资源的时域位置，否则，终端设备101仍将根据该第二信息确定传输资源的时域位置。该RNTI可以为预设的。
具体来说，可以由网络设备102为终端设备101配置与本申请所涉及的第一类业务(如CT类业务)对应的RNTI，该RNTI可用于网络设备102对一部分第二信息进行加扰，这些第二信息用于调度属于第一类业务的上行和/或下行数据。终端设备101在根据该RNTI解扰第二信息后，可根据第一参考点确定这些上行和/或下行数据的传输资源，从而终端设备101可通过由第一参考点确定的传输资源传输第一类业务的上行和/或下行数据。应理解，也可由协议定义或通过预配置的方式设置以上第一类业务对应的RNTI。
另外，由网络设备102为终端设备101配置RNTI的生成方式，在需要根据第一参考点确定传输资源的时域位置时，网络设备102可采用该方法生成RNTI并进行第二信息的加扰，以指示终端设备101根据第一参考点确定传输资源的时域位置。应理解，也可由协议定义或通过预配置的方式设置以上RNTI的生成方式。
示例性的，网络设备102预先配置了第一类业务对应的PDCCH的时频资源，此后根据该PDCCH的时频资源生成RNTI，例如，根据PDCCH的时域位置的索引(如PDCCH所占用的第一个/最后一个时隙/符号等的编号)、PDCCH的频域位置、PDCCH的频域资源索引、PDCCH的资源大小或者PDCCH的聚合等级等信息中的部分或全部信息，确定该RNTI。所述聚合等级为PDCCH时频资源的组合方式，不同聚合等级对应了不同的资源大小。举例来说，可采用以下公式确定RNTI：
RNTI＝R+j*S+k*T；(公式一)
其中，R表示PDCCH的第一个符号在系统帧内的索引，S表示PDCCH的频域位置的索引，T表示PDCCH的所占用的资源大小，j、k均为正整数。
可选的，网络设备102可将第三信息承载于RRC或者MAC CE消息，并向终端设备101发送该第三信息。
应理解，以上所述终端设备101确定根据第一参考点确定传输资源的时域位置，可以是指终端设备101根据第一参考点确定用于传输初传数据的传输资源的时域位置。在终端设备101进行重传数据的传输时，可采用与初传数据相同的方式确定传输资源的时域位置。 另外，对于初传数据的传输，终端设备101也可均根据第一参考点确定传输资源的时域位置，无需根据第二信息或以上所述第三信息判断是否根据第一参考点确定传输资源的时域位置。
还应理解，以上所述终端设备101确定根据第一参考点确定传输资源的时域位置，可以是指终端设备101根据第一参考点确定用于传输网络设备102以半静态调度方式所调度数据的传输资源的时域位置。对于网络设备102以半静态调度方式所调度数据的数据，终端设备101也可均根据第一参考点确定传输资源的时域位置，无需根据第二信息或以上所述第三信息判断是否根据第一参考点确定传输资源的时域位置。
在实施中，对于网络设备102配置，或通过协议定义或预设置的方式确定第一周期的方案，若终端设备101确定在一个循环周期内接收到的第二信息的时域位置位于该循环周期内的第一参考点的时域位置之前，则终端设备101可根据该第一参考点确定传输资源的时域位置。
如图16中的(a)所示，若终端设备101接收的第二信息的时域位置如图16的(a)中箭头位置所示，可见，在该第二信息所在的第一周期内，该第二信息的时域位置位于第一参考点(如图16的(a)中实心圆位置所示)的时域位置之前，则终端设备101可根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源。
又如图16中的(b)所示，若终端设备101接收的第二信息的时域位置如图16的(b)中箭头位置所示，可见，在该第二信息所在的第一周期内，该第二信息的时域位置位于第一参考点(如图16的(b)中实心圆位置所示)的时域位置之后，则终端设备101可不根据该第一参考点确定该第二信息调度的上行和/或下行数据的传输资源。此时，终端设备101可根据该第二信息的时域位置确定传输资源的时域位置。或者，终端设备101可根据下一个第一周期内的第一参考点，确定传输资源的时域位置。
在S104所示步骤中，在根据第一参考点确定传输资源的时域位置时，终端设备101可以将该第一参考点的时域位置作为传输资源的时域位置。或者，终端设备101可根据偏移量，在第一参考点的时域位置的基础上加上该偏移量确定传输资源的时域位置，其中，该偏移量的符号可以是正或负，该偏移量可以是网络设备102配置的，也可以是根据协议定义或预配置方式确定的。
示例性的，以终端设备101根据第二信息的调度向网络设备102发送上行数据为例，若第一参考点的时域位置为第n个时间单位。本实施例以时间单位为时隙为例进行说明，其他时间单位类似。根据该第一参考点确定的传输资源的时域位置可位于第

表示对Z进行向下取整运算。
以上K 2的取值可参照PUSCH配置表，该表可用于描述PUSCH可能的时域资源的位置与K 2的取值之间的映射，该表可以由网络设备102配置，或者由协议定义或者通过预设置的方式确定。网络设备102可通过DCI或者其它信息指示终端设备101PUSCH配置表中的某一行，以指示时域资源的位置，例如，网络设备102可通过DCI指示PUSCH配置表 中的行索引。PUSCH配置表可具体可以是如表二所示的正常循环前缀的PUSCH配置表，或者也可以是其他类型的PUSCH配置表，如扩展循环前缀的PUSCH配置表。
其中，如表二所示为正常循环前缀的PUSCH配置表。

表二中，j的取值可根据μ PUSCH或者μ PDCCH确定。
具体的，可参照μ PUSCH与j取值之间的对应关系表或μ PDCCH与j取值之间的对应关系表，确定j的取值。以上所述该μ PUSCH与j取值之间的对应关系表和/或μ PDCCH与j取值之间的对应关系表，可由网络设备102配置，或者由协议定义或通过预配置的方式确定。以μ PUSCH与j取值之间的对应关系表为例，该表可以如表三所示。

表三
由于μ PUSCH与PUSCH相关，μ PUSCH的取值可被视为已知量，从而可根据表三确定j的取值。
另外， μPDCCH与PDCCH相关，μ PDCCH的取值可被视为已知量，从而可根据μ PDCCH与j取值之间的对应关系表确定j的取值。其中，μ PDCCH与j取值之间的对应关系表的设置方式，可参照表三。
