为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，5G移动通信系统应运而生。ITU为5G以及未来的移动通信系统定义了三大类应用场景：增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及mMTC。
典型的eMBB业务有：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用，这些业务的主要特点是要求超高可靠性、低延时，传输数据量较少以及具有突发性。典型的mMTC业务有：智能电网配电自动化、智慧城市等，主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感，这些mMTC终端需要满足低成本和非常长的待机时间的需求。
不同业务对移动通信系统的需求不同，如何更好地同时支持多种不同业务的数据传输需求，是当前5G移动通信系统所需要解决的技术问题。例如，如何同时支持mMTC业务和eMBB业务，或者同时支持URLLC业务和eMBB业务。
5G标准对mMTC的研究还没有广泛开展。
目前，标准中将mMTC业务的UE称为REDCAP UE，即低复杂度或低能力的UE，该类UE可能在带宽、功耗、天线数等方面比其他UE复杂度低一些，如带宽更窄、功耗更低、天线数更少等。该类UE也可以称为NRL UE。
目前，UE的随机接入包括基于竞争和非竞争两种。
如图2所示，4步随机接入的基于竞争的随机接入过程包括：
S201，UE向接入网设备发送随机接入前导码(random access preamble)，也可以称为第一消息(Msg1)。随机接入前导码的作用是通知接入网设备有一个随机接入请求，并使得接入网设备能估计其与UE之间的传输时延，以便接入网设备校准上行定时(uplink timing)并将校准信息通过定时提前指令(timing advance command)告知UE。
S202，接入网设备在检测到随机接入前导码后向UE发送随机接入响应(random access response，RAR)，也可以称为第二消息(Msg2)。随机接入响应可以但不限于包含S201中所收到随机接入前导码的序列编号、定时提前指令、上行资源分配信息和小区无线网络临时标识等。
S203，UE接收随机接入响应，如果该随机接入响应中的随机接入前导码的序列编号所指示的随机接入前导码和S201中UE向接入网设备发送的随机接入前导码相同，则UE认为该随机接入响应是针对该UE的随机接入响应，即UE接收到了该UE的随机接入响应。UE接收到随机接入响应后，在随机接入响应指示的上行信道资源上发送上行消息，例如在Msg3中发送物理上行共享信道(physical uplink shared channel，PUSCH)，也称为第三消息(Msg3)。其中，Msg3可以携带唯一的用户标识。
S204，接入网设备接收到UE的上行消息，向接入的UE返回冲突解决消息，也称为第四消息(Msg4)。接入网设备在冲突解决消息中将携带Msg3中的唯一用户标识以指定接入成功的UE，而其他没有接入成功的UE将重新发起随机接入。
在基于竞争的过程中，接入网设备在Msg3之前无法获取UE的标识信息。
如图3所示，基于非竞争的随机接入过程包括：
S301，接入网设备为UE分配random access preamble。
S302，UE向接入网设备发送专用的random access preamble。
S303，接入网设备向UE发送RAR。
在基于非竞争的随机接入过程中，接入网设备在发送RAR消息之前可以获取UE的标识信息。接入网设备可以根据UE的标识信息获取UE的信息，如UE属于哪类终端，如现有终端(eMBB终端)、REDCAP终端、传统终端。
在RAR中包括接入网设备对上行传输的调度(UL grant)信息。其中，包括14bits的频域资源分配指示域(frequency domain resource allocation)。频域资源分配指示域用于指示频域资源分配(frequency domain resource allocation，FDRA)信息，即上行传输频域资源的起始资源位置以及长度。如表1所示。
表1
Figure PCTCN2020132986-appb-000003
上行传输频域资源的位置是通过指示起始资源位置和长度的联合编码值来确定的，如果上行传输可分配资源数即初始上行带宽区域的物理资源块(physical resource block，PRB)数量为
Figure PCTCN2020132986-appb-000004
则FDRA需要指示的状态为
Figure PCTCN2020132986-appb-000005
个，FDRA需要的比特数为
Figure PCTCN2020132986-appb-000006
如果可分配的资源带宽≤180RBs时，NR协议规定会按照DCI format 0_0的方式，将频域资源指示域截短到长度
Figure PCTCN2020132986-appb-000007
Figure PCTCN2020132986-appb-000008
保留其中低比特位(least significant bits，LSB)。
UL grant中还包括1bit的跳频标识用于指示本次上行传输是否跳频。如果跳频则会根据系统带宽将最高有效位(most significant bits，MSB)1bit或2bits的即N UL,hop指示第二跳的频域位置相对第一跳的偏移值大小。如表2所示，如果可分配的资源带宽
Figure PCTCN2020132986-appb-000009
时，N UL，hop为1比特，如果可分配的资源带宽
Figure PCTCN2020132986-appb-000010
时，N UL,hop为2bit。
表2
Figure PCTCN2020132986-appb-000011
下面对不同子载波间隔(sub-carrier spacing，SCS)、不同带宽下指示上行传输频域资 源的位置所需要的比特数进行举例，其中，低频频段(frequency range 1，FR1)可以如表3所示，高频频段(frequency range 2，FR1)可以如表4所示。
表3
Figure PCTCN2020132986-appb-000012
表4
Figure PCTCN2020132986-appb-000013
根据上述表3和表4，一些带宽配置(例如表3带宽小于20MHz或表4100MHz带宽)下，指示上行传输频域资源的位置所需要的比特数均小于14比特。
以第一终端设备在FR1的情况举例。第一终端设备支持的最大带宽如果在20M以下，对应的最大RB数大概小于或等于106。指示上行传输频域资源的位置所需要的比特数最多为13bits，频域资源指示域会存在至少剩余1bits不用的情况。对于小带宽(如5M/10Mhz)，或高频(FR2)SCS较大(60/120/240kHz)情况。此时，空闲比特更多。例如，当SCS＝60kHz，带宽＝20MHz包括24RB，频域资源指示需要9bits。跳频信息需要2bits，资源偏移值4bits。第一终端设备可以为低能力的终端设备，例如REDCAP UE等。
由于第一类终端设备可支持的带宽较窄，在第一类终端设备的用户数比较多情况下，都集中在较窄的带宽内，造成业务阻塞和传输/接入时延的增大。第一类终端设备可以为低能力的终端设备，例如REDCAP UE。
基于此，本申请实施例提供一种资源指示方法及装置，用于解决REDCAP UE容易造成业务阻塞的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例中可以在RAR UL grant中指示第二资源在第一资源中的位置，第一资源的大小大于第一终端设备可支持的资源的大小。第二资源包括的资源的数量小于或等于第一终端设备可支持的资源的数量。如图4所示，左侧为第一资源，右侧为第二资源，第一 资源与第二资源的上边界对齐。使得第一终端设备的可用于分配的资源范围(如，第二资源)不局限于能力可支持(第一终端设备能力比较低)或配置的在较窄的带宽内，从而可以避免造成业务阻塞，更好的进行负载均衡。第一资源可以是广播消息通知的初始BWP资源。如，第一资源还可以为第二终端设备的初始BWP资源，第二终端设备支持的带宽大于第一终端设备支持的带宽。第一终端设备支持的带宽可以理解为第一终端设备支持的最大带宽。又例如，第一资源也可以是接入网设备工作的频域资源，如载波等。
应理解，本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一(项)个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序，也不代表个数。
下面结合附图对本申请实施例提供的方法进行具体说明。
实施例一：参见图5，为本申请提供的一种资源指示方法的流程示意图。该方法包括：
S501，接入网设备确定第一信息和第二信息，第一信息指示第二资源在第一资源中的位置，所述第一资源包括的资源的数量大于所述第一终端设备可支持的资源的数量；所述第二资源包括的资源的数量小于或等于所述第一终端设备可支持的资源的数量；所述第二信息指示第三资源在所述第二资源中的位置，所述第二资源包括的资源的数量大于或等于所述第三资源包括的资源的数量。示例性的，第二信息指示的内容可以如图6所示。
示例性的，第一终端设备可以为低能力的终端设备，例如REDCAP UE等。
其中，第一资源、第二资源、第三资源的大小可以理解为资源的时域范围、频域范围等，也可以理解为包括的资源的数量。
其中，本申请实施例中第一资源、第二资源、第三资源可以为时域资源、频域资源、空域资源、码域资源、功率资源等。示例性的，时域资源的资源单位可以为无线帧、子帧、半帧、时隙、迷你时隙、符号等。频域资源的资源单位可以为子载波(sub-carrier)、资源块(resource block，RB)、资源单元(resource element，RE)、资源单元组(RE group，REG)、REG束(REG bundle)、控制信道单元(control channel element，CCE)、载波。例如，若带宽为20MHz，在子载波间隔为15kHz时，包括的资源块数量可以为106个RB。
一种示例性说明中，第一终端设备可支持(或者可分配)的资源的大小，可以理解为支持的带宽所包括资源块数量。支持的带宽所包括资源块数量可以是第一终端设备发送和/或接收时能够占用的最大频域资源块的数量。如，第一终端设备能够接收信号的最大带宽，和/或第一终端设备能够发送信号的最大带宽等。举例说明，支持的带宽为20MHz带宽，在子载波间隔为15kHz时，支持的资源块数量为106个RB。
下面以第一资源为频域资源为例对第一资源进行示例性说明。
一种实现方式中，第一终端设备可以通过接入网设备广播的系统消息获取第一资源的信息。第一资源还可以为第二终端设备的初始BWP。如，第二终端设备的UE能力高于第 一终端设备。能力包括可支持的带宽、处理数据的速度、支持的天线数、支持的最大调制编码方式中的至少一种。
另一种实现方式中，该第一资源可以是接入网设备工作的载波。在该实现方式中，第一资源可以是预定义好的资源位置和带宽。可选的，第一终端设备在入网前可以获取该第一资源的信息。
又一种实现方式中，该第一资源也可以是接入网设备通过信令通知的。如接入网设备可以通过系统消息或广播消息指示用户使用一段频率范围。第一终端设备通过接收系统消息或广播消息获取第一资源的信息。
一种实现方式中，第二资源的大小可以为该第一终端设备可支持(或者可分配)的资源的大小。
在一些实施例中，第二资源的大小可以是根据第一终端设备的能力确定的，也可以是接入网设备配置的。其中，第二资源的大小是根据第一终端设备的能力确定的，可以指第二资源的大小为第一终端设备收和/或发信号能够支持的资源的最大值。第二资源的大小是接入网设备配置的，可以指接入网设备通过信令指示第一终端设备的收和/或发信号的资源的大小范围，或接入网设备调度第一终端设备收和/或发信号的资源的大小范围。
以第二资源为频域资源为例，第二资源的频域范围可以是根据第一终端设备的能力确定的，也可以是接入网设备配置的。其中，第二资源的频域范围是根据第一终端设备的能力确定的，可以指第二资源的频域范围为第一终端设备收和/或发信号能够支持的最大带宽或者最大资源数量。第二资源的频域范围是接入网设备配置的，可以指接入网设备通过信令指示第一终端设备的收和/或发信号的最大带宽或者最大资源数量，或接入网设备调度第一终端设备收和/或发信号的最大带宽或者最大资源数量。
S502，接入网设备向第一终端设备发送第一信息和第二信息。相应的，第一终端设备接收第二信息。
S503，第一终端设备确定第一资源。
需要说明的是，步骤S502和步骤S503没有严格的先后顺序，可以先执行步骤S502后执行步骤S503，也可以先执行步骤S503后执行步骤S502，也可以同时执行步骤S502和S503。
S504，第一终端设备在第三资源上进行信息传输。如，第一终端设备在第三资源上进行信息发送。相应的，接入网设备在第三资源上进行信息接收。如，第一终端设备在第三资源上进行信息接收。相应的，接入网设备在第三资源上进行信息发送。
示例性的，第一终端设备在第三资源上传输的信息可以为控制信息、数据信息、寻呼信息、随机接入信息、随机接入相应信息、广播信息等。控制信息可以包括上行控制信息，下行控制信息。数据信息可以包括上行数据信息，下行数据信息。
本申请实施例中，接入网设备可以将第二资源配置在第一资源的任意位置，其中，第一资源的大小大于第一终端设备可支持的资源的大小。第二资源的大小不超过第一终端设备可支持的资源的大小。使得第二资源不再固定在一个固定位置，从而第一终端设备的调度资源可以不局限于能力可支持的区域或配置的较少的资源内。通过这种方式，不同第一终端设备的调度资源可以分布在宽带资源的不同位置，从而可以避免造成业务阻塞，更好的进行负载均衡。
一种示例性说明中，第二信息可以为RAR中的frequency domain resource allocation。 需要说明的是，目前frequency domain resource allocation的比特数固定为14比特，但是本申请实施例中第二信息的比特数可以为根据第一终端设备的资源数量或第二资源的大小确定的。例如，第二信息的比特数可以满足如下公式：
Figure PCTCN2020132986-appb-000014
其中，N为该第一终端设备传输信息的资源数量，也可以理解为该第一终端设备上行传输可分配资源数，还可以理解为该第一终端设备的initial BWP的PRB数量，或者N为第二资源包括的资源的数量，或者第一终端设备支持的最大的资源数量。
一种实现方式中，第二信息可以通过目前PUSCH frequency domain resource allocation中的
Figure PCTCN2020132986-appb-000015
个比特进行指示。随机接入相应中还包括第一信息。第一信息和第二信息需要的比特数小于或等于14比特。或，第一信息和第二信息需要的比特数小于或等于第二第一终端设备的频域资源分配指示域包括的比特数。通过上述实现方式，可以减低信令开销。
一种实现方式中，第一信息和/或第二信息在随机接入响应信息(RAR)中传输。例如，接入网设备可以通过RAR向第一终端设备发送第一信息和第二信息。
示例性的，随机接入响应信息可以是随机接入物理下行控制信道(physical downlink control channel，PDCCH)的响应信息、随机接入物理下行共享信道(physical downlink shared channel，PDSCH)的响应信息等中的至少一种，随机接入响应信息中包括上行授权信息。
一种示例性说明中，RAR中UL grant包括的信息可以如表5所示。
表5
Figure PCTCN2020132986-appb-000016
可选的，UL grant信息还可以包括其他信息，如跳频标识、MCS、TPC command for PUSCH等，具体可以参阅上述表1。
一种实现方式中，RAR中的授权信息中包括的比特数小于或等于前向版本中的RAR授权信息包括的比特数。如，前向版本为NR R15版本。
一种实现方式中，RAR中的授权信息中包括的比特数小于或等于28比特。
一种实现方式中，RAR中的授权信息中频域资源分配指示域包括的比特数小于14比特。并且，RAR中的授权信息中包括第一信息，所述第一信息为指示第二资源在第一资源中的位置信息。
下面以第三资源为第一终端设备的上行调度资源，第二资源为第一终端设备可支持的带宽，第一资源的带宽大于第二资源的带宽为例对本申请实施例的资源指示方法进行说明。
如果按照现有FDRA比特数，因为UE支持的带宽小，需要的频域资源分配指示比特数小于现有FDRA比特数，因而会导致PUSCH frequency domain resource allocation域存在空闲比特。本申请实施例中可以采用该空闲比特来指示第二资源在第一资源内的频域偏移值(即第一信息)。
一种示例性说明中，第一信息可以指示第二资源的起始位置S1。第二信息可以指示第三资源的起始位置相对于第二资源的起始位置的偏移值S2以及第三资源的长度L。
其中，S1可以是该第一终端设备的可分配资源(即第二资源)的最小RB索引(index)相对于参考点的偏移值。一个示例中，第一资源可以为接入网设备为第一终端设备配置的初始带宽区域资源，参考点可以为初始带宽区域资源的可分配资源的最小RB index。另一个示例中，第一资源可以接入网设备指示的频域范围，参考点可以为接入网设备指示的资源位置。
第一信息可以指示S1。其中，S1可以为预配置的值(例如RB的整数倍、10M、20M、BWP/4、BWP/2等)。或者，第一信息也可以包括一个指示值，S1也可以根据该指示值按照预设规则计算的值。例如S1可以等于第一信息携带的指示值*该第一终端设备的初始带宽的倍数。例如S1可以等于第一信息携带的指示值*该第一终端设备可支持的带宽。例如S1可以等于第一信息携带的指示值*该第一终端设备可支持的带宽的倍数。其中，S1可用3bit指示第二资源的起始位置相对于第一资源的起始位置的偏移值。偏移值可以是预定义的值、或者接入网设备通过信令提前指示的值、或者将第一信息携带的指示通过预定义的方式计算的值。
示例性的，偏移值可以通过如下预定义的方式确定：偏移值可以为根据第一资源包括的RB数量和偏移值的候选值个数确定的。如，S1等于W/偏移值的候选值个数。如，W为接入网设备配置的initial BWP资源(如第一资源)包括的RB数量。如W为270。偏移值的候选值个数为8。则S1指示的值i对应的偏移值＝W/8*i。可选的，为了使结果是整数可以选择上取整或下取整。或者，偏移值＝(W-该第一终端设备支持带宽)/(8-1)*i。或者，偏移值＝(W-第二资源大小)/(8-1)*i。该第一终端设备支持带宽(如第二资源或预设值或预配置值)可以是根据该第一终端设备能力发送信号的最大带宽确定、或者根据该第一终端设备能力接收信号的最大带宽确定、或者接入网设备指示该第一终端设备当前收发支持的最大带宽等。
第二信息可以指示S2和L。如，S2和L用11比特指示。
在一些实施例中，该第一终端设备在满足第一特性时获取本申请实施例提供的UL grant信息包括第一信息和第二信息。第一终端设备在满足第二特性时可以获取现有协议定义的UL grant信息。如第三信息。第三信息携带如下信息中至少一项：第三资源在第二资源中的位置信息、跳频信息。示例性的，跳频信息可以包括跳频指示信息、跳频偏移值中的至少一项。其中，跳频指示信息用于指示是否跳频。所述第一特性为BWP带宽大于或等于第一终端设备可支持的带宽。示例性的，所述BWP为初始BWP。所述第二特性为BWP带宽小于或等于第一终端设备可支持的带宽。如第一终端设备可支持20MHz带宽，第一特性为第一终端设备的初始BWP带宽大于或等于20MHz。第二特性为第一终端设备的初始BWP带宽小于或等于20MHz。
在另一些实施例中，该第一终端设备既可以支持获取第一信息和第二信息，也可以获取第三信息。即获取的UL grant信息既可以包括第一信息和第二信息，还可以包括第三信息。例如，在第一终端设备的初始带宽较小(如5M/10Mhz)，或者，工作在高频(如FR2)，或者SCS较大(例如60/120/240kHz)情况下，获取的UL grant信息既可以包括第一信息和第二信息，还可以包括第三信息。例如，SCS＝60kHz，带宽＝20MHz，包括24RB，FDRA需要9bit，跳频信息需要2bit，资源偏移值4bit。
通过上述方式，可以更充分的利用当前的空闲比特进行信息指示。
一种可能的实施方式中，第一终端设备还可以确定第四资源的信息(例如第四资源的位置、大小等)。第一终端设备在第四资源上检测控制信息，如PDCCH。或者，第一终端设备在第四资源上发送物理上行控制信道(physical uplink control channel，PUCCH)信息。
一种实现方式中，第四资源的位置可以是在第一资源内的固定位置。如，第四资源的资源起始位置为第一资源的频域最低位置。第四资源的带宽可以等于第一终端设备支持的带宽。第一终端设备可以根据在第四资源检测到的控制信息确定第五资源的位置，第一终 端设备在第五资源上进行数据信息传输，如PDSCH或者PUSCH。

A4，第一终端设备在完成PDSCH1/PUSCH1的传输之后，第一终端设备在时间t3将信号接收范围调整到第一频率。第一终端设备在第一频率监测PDCCH。与t2类似，t3也可以是预定义的或指示的，具体可以参阅t2的相关描述，这里不再重复赘述。

实施例二：参见图9，为本申请提供的一种资源指示方法的流程示意图。该方法包括：
S901，接入网设备确定第四信息，所述第四信息指示第三资源在所述第一资源中的位置信息和资源大小信息。所述第一资源包括的资源的数量大于所述第一终端设备可支持的资源的数量。所述第三资源包括的资源的数量小于或等于所述第一终端设备可支持的资源的数量。
S902，接入网设备向第一终端设备发送第四信息。相应的，第一终端设备接收接入网设备发送的第四信息。
S903，第一终端设备确定第一资源。
需要说明的是，步骤S902和步骤S903没有严格的先后顺序，可以先执行步骤S902后执行步骤S903，也可以先执行步骤S903后执行步骤S902，也可以同时执行步骤S902和S903。
S904，第一终端设备在第三资源上进行信息传输。
示例性的，第一终端设备在第三资源上传输的信息可以为控制信息、数据信息、寻呼信息、随机接入信息、随机接入相应信息等。控制信息可以包括上行控制信息，下行控制信息。数据信息可以包括上行数据信息，下行数据信息。
本申请实施例中，接入网设备可以将第一终端设备的调度资源配置在一个宽带资源的任意位置，使得第一终端设备的调度资源可以不局限于能力可支持的区域或配置的较少的资源内。通过这种方式，不同第一终端设备的调度资源可以分布在宽带资源的不同位置，从而可以避免造成业务阻塞，更好的进行负载均衡。
需要说明的是，本申请实施例中，第一资源、第三资源的大小可以理解为时域范围、频域范围等。也可以理解为包括的资源的数量。
其中，本申请实施例中第一资源、第三资源可以为时域资源、频域资源、空域资源、码域资源、功率资源等。示例性的，时域资源的资源单位可以为无线帧、子帧、半帧、时隙、符号等。频域资源的资源单位可以为子载波(sub-carrier)、资源块(resource block，RB)、资源单元(resource element，RE)、资源单元组(RE group，REG)、REG束(REG bundle)、控制信道单元(control channel element，CCE)、载波。例如，若带宽为20MHz，在子载波间隔为15kHz时，包括的资源块数量可以为106个RB。
一种示例性说明中，第一终端设备可支持(或者可分配)的资源的大小，可以理解为支持的带宽所包括资源块数量。支持的带宽所包括资源块数量可以是第一终端设备发送和/或接收时能够占用的最大频域资源块的数量，如，第一终端设备能够接收信号的最大带宽，和/或第一终端设备能够发送信号的最大带宽等。举例说明，支持的带宽为20MHz带宽，在子载波间隔为15kHz时，支持的资源块数量为106个RB。
下面以第一资源为频域资源为例对第一资源进行示例性说明。
一种实现方式中，第一资源可以为第一终端设备的初始BWP。可选的，第一终端设备可以通过接入网设备广播的系统消息获取第一资源的信息。可选的，第一资源可以为第二终端设备的初始BWP。第二终端设备为能力高于第一终端设备。如，第二终端设备支持的带宽大于第一终端设备，第二终端设备的数据处理时间小于第一终端设备的处理时间，或第二终端支持的最大传输层数大于第一终端设备支持的最大传输层数。
另一种实现方式中，该第一资源可以是接入网设备工作的载波。在该实现方式中，第一资源可以是预定义好的资源位置和带宽的传输资源。可选的，第一终端设备在入网前可以获取该第一资源的信息。
又一种实现方式中，该第一资源也可以是接入网设备通过信令通知的，如接入网设备可以通过系统消息或广播消息指示一段频率范围为用户使用。第一终端设备通过接收系统消息或广播消息获取第一资源的信息。
一种示例性说明中，第四信息可以指示第三资源在第一资源中的起始位置S和长度L。
S可以大于第一终端设备支持的资源的大小，L可以小于或等于第一数值。例如，如果第一资源包括的资源的数量为N L，第一数值为N r，则S的取值范围可以为[0,N L-1]，L的取值范围可以是[1,N r]，且S+L≤N L。其中，所述第一数值大于或等于所述第三资源包括的资源的数量。第一数值小于或等于所述第一终端设备可支持的资源的数量。或者，第一数值为接入网设备预配置的值。
在一些实施例中，第一数值可以是根据第一终端设备的能力确定的，也可以是接入网设备配置的。其中，第一数值是根据第一终端设备的能力确定的，可以指第一数值为第一终端设备收和/或发信号能够支持的资源的最大值。第一数值是接入网设备配置的，可以指接入网设备可以通过信令指示给第一终端设备的后续收和/或发信号的资源的大小，或接入网设备调度第一终端设备收和/或发信号的资源的大小。
可选的，第四信息的比特数可以为根据第一资源的大小以及第一数值确定的。
例如，S的可选取值有N L个，需要log 2(N L×(N L+1)/2)比特进行指示。S的取值范围在第一资源范围内。L的可选取值有Nr个，需要log 2(N r×(N r+1)/2)比特进行指示。L的取值范围小于或等于第一终端设备支持的最大带宽。则第四信息可以包括[log 2(N L×(N L+1)/2)+log 2(N r×(N r+1)/2)]比特。
又例如，第四信息的比特数可以为log 2(状态值)，其中，第四信息的状态值可以如表6所示。

在一些实施例中，起始点的位置S可以是接入网设备配置的BWP/载波带宽N L范围内的任意值。如，初始BWP。但长度L需要根据第一数值限制到Nr。如长度L为第一终端设备传输中可支持的最大RB数。即起点S和长度L的取值范围并不相同。
为了节省开销，进一步的，可以将S的粒度配置为RB的整数倍，如2/4/8/16等。如，粒度为4，假设第一资源的带宽为50M的宽带，第一数值为20M带宽包括的RB数，即N L＝270，N r＝106，则第四信息的比特数为13bits。
在一些实施例中，该第一终端设备在满足第一特性时获取本申请实施例二提供的控制信息包括第四信息。第一终端设备在满足第二特性时可以获取现有的控制信息，即第三信息，第三信息携带如下信息中至少一项：第三资源在第一资源中的位置信息、跳频信息，示例性的，跳频信息可以包括跳频指示、跳频偏移值中的至少一项，其中，跳频指示用于指示是否跳频。
示例性的，所述第一特性为所述第一终端设备BWP大于或等于第一终端设备可支持的带宽。如，所述BWP为初始BWP。
所述第二特性为所述第一终端设备BWP小于或等于第一终端设备可支持的带宽。如，所述BWP为初始BWP。
在另一些实施例中，该第一终端设备既可以支持获取第四信息，也可以获取第三信息，即获取的UL grant信息既可以包括第四信息，还可以包括第三信息。例如，在第一终端设备的初始带宽较小(如5M/10Mhz)，或者，工作在高频(如FR2)，或者SCS较大(例如60/120/240kHz)情况下，获取的UL grant信息既可以包括第四信息，还可以包括第三信息。
通过上述方式，可以更充分的利用当前的空闲比特进行信息指示。
一种可能的实施方式中，第一终端设备还可以确定第四资源的信息(例如第四资源的位置、大小等)，第一终端设备在第四资源上检测控制信息，如PDCCH或者物理上行控制信道(physical uplink control channel，PUCCH)。具体的，第四资源的确定方式可以参阅上述实施例一的相关描述，这里不再重复赘述。
一种实现方式中，第四资源的位置可以是在第一资源内的固定位置。如，第四资源的 资源起始位置为第一资源的频域最低位置。第四资源的带宽可以等于第一终端设备支持的带宽。第一终端设备可以根据在第四资源检测到的控制信息确定第五资源的位置，第一终端设备在第五资源上检测数据信息，如PDSCH或者PUSCH。
可选的，第一终端设备在第五资源接收或发送信息后，可以将接收信号频率范围调整回到控制信号的接收位置，即将接收信号频率范围调整回到第四资源。第五资源和第四资源不重合，第五资源包括在第一资源内。
具体可以参阅实施例一中图7A或图7B的相关描述。
另一种实现方式中，第一终端设备根据也可以根据第一信息(例如第二资源的位置和/或长度)确定第四资源的信息(例如第四资源的位置、长度等)。
