Description

一种资源指示的方法及装置 技术领域
本申请实施例涉及无线通信领域，尤其涉及一种资源指示的方法及装置。
背景技术
随着移动通信技术的发展，第五代(the fifth generation，5G)移动通信技术已成为全球研发的热点。移动互联网和物联网作为未来通信发展的主要驱动力，将在人们的居住、工作、休闲和交通等领域产生巨大影响，5G业务需求呈现多样化。例如，在工业控制场景中，控制器需要和执行器之间保持时间同步。控制器给执行器发送控制信令，指示执行器在确定的时间执行命令，若执行器与控制器对时间的认知不同，即时间不同步，会导致执行器在错误的时间执行命令，导致任务执行失败。网络设备作为终端设备的集中控制器，可以作为终端设备的时间同步源，向终端设备发送指示信息，使小区内所有的终端设备均与网络设备保持时间同步，间接的达到终端设备之间的时间同步。
网络设备和终端设备可以周期性地交互时间信息(如：时效性网络(time sensitive networking，TSN)信息)，根据时间信息调整时钟保持时间同步。例如，在配置资源(如：免授权调度(configured grant，CG)资源或半静态调度(semi-persistent scheduling，SPS)资源)上传输TSN信息。但是，由于业务周期(如：TSN信息的周期)与配置资源的周期不同，在业务到达后，若业务到达的时刻与发送配置资源的时刻不同，则等到发送配置资源的时刻后发送TSN信息。在一些实施例中，如图1中的(a)所示，配置资源的周期大于业务周期，传输时间信息的时延较大；如图1中的(b)所示，如果配置资源的周期小于业务周期，有些配置资源(如图中画“×”的时刻对应的资源)上不会传输业务周期，浪费配置资源。因此，如何提高系统资源的利用率，是一个亟待解决的问题。
发明内容
本申请提供一种资源指示的方法及装置，解决了如何提高系统资源的利用率的问题。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供了一种资源指示的方法，该方法可应用于网络设备，或者该方法可应用于可以支持网络设备实现该方法的通信装置，例如该通信装置包括芯片系统。所述方法包括：通过发送第一指示信息来指示N个第一时频资源中的M个第一时频资源，并以N个第一时频资源为周期，在N个第一时频资源中的M个第一时频资源上发送或接收数据。其中，M个第一时频资源中的每个第一时频资源用于传输数据，N和M均为正整数。
本申请实施例提供的资源指示的方法，在满足数据传输时延的前提下，选取最小的资源循环周期和最少的资源使用个数，使业务和资源周期达到最佳的匹配关系，因 此，网络设备在指定的第一时频资源上接收或发送数据，并通过指示发送数据的第一时频资源，使得终端设备可以在指定的第一时频资源上发送或接收数据，从而，降低了指示信息的开销，提高了系统资源利用率。
在一种可能的设计中，所述方法还包括：根据第一起始时刻、第一周期、第二起始时刻和第二周期确定第一时频资源的个数N中的M个第一时频资源，第一起始时刻为发送第一时频资源的起始时刻，第一周期为发送第一时频资源的周期，第二起始时刻为数据的业务周期的起始时刻，第二周期为数据的业务周期，第二周期大于第一周期。本申请实施例提供的确定资源分配的方法，在满足数据传输时延的前提下，选取最小的资源循环周期和最少的资源使用个数，使业务和资源周期达到最佳的匹配关系，以便于网络设备在指定的第一时频资源上接收或发送数据，从而，降低了指示信息的开销，提高了系统资源利用率。
在另一种可能的设计中，所述方法还包括：发送第一资源配置信息，第一资源配置信息包含第一起始时刻和第一周期。从而，以便于终端设备根据第一指示信息和第一资源配置信息确定接收数据的第一时频资源，在确定的第一时频资源上接收数据。
在另一种可能的设计中，所述方法还包括：发送第二资源配置信息，第二资源配置信息包含第三起始时刻和第三周期，第三起始时刻为发送第二时频资源的起始时刻，第三周期为发送第二时频资源的周期；根据第三起始时刻、第三周期、第二起始时刻和第二周期确定第二时频资源的个数K中的L个第二时频资源，第二周期大于第三周期，K和L均为正整数，第一指示还用于指示K个第二时频资源中的L个第二时频资源；以K个第二时频资源为周期，在K个第二时频资源中的L个第二时频资源上发送或接收数据。从而，以便于终端设备根据第一指示信息和第二资源配置信息确定接收数据的第二时频资源，在确定的第二时频资源上接收数据。
在另一种可能的设计中，第一指示信息包括传输数据的第一时频资源的标识和传输数据的第二时频资源的标识。从而，以便于终端设备根据时频资源的标识确定传输数据的时频资源，在指定的第一时频资源和第二时频资源上发送或接收数据，从而，降低了指示信息的开销，提高了系统资源利用率。
第二方面，本申请提供了一种资源指示的方法，该方法可应用于终端设备，或者该方法可应用于可以支持终端设备实现该方法的通信装置，例如该通信装置包括芯片系统。所述方法包括：接收到第一指示信息，以N个第一时频资源为周期，在N个第一时频资源中的M个第一时频资源上接收或发送数据。第一指示信息用于指示N个第一时频资源中的M个第一时频资源，M个第一时频资源中的每个第一时频资源用于传输数据，其中，N和M均为正整数。
本申请实施例提供的资源指示的方法，在满足数据传输时延的前提下，能够使业务和资源周期更好的匹配，终端设备在指定的第一时频资源上接收或发送数据，从而，提高了系统资源利用率。
另外，由于第一时频资源是半静态资源，接收端(网络设备或终端设备)可以对第一时频资源进行盲检测接收数据。如果接收端对配置的所有第一时频资源进行盲检测，有些第一时频资源上未承载数据，会导致浪费了接收端的功耗。本申请实施例提供资源指示的方法，接收端对第一指示信息指示的第一时频资源进行盲检测接收数据， 避免了对配置的所有第一时频资源进行盲检测，不仅有效地提高了时频资源的利用率，还节省了接收端的功耗。

在另一种可能的设计中，第一指示信息包括传输数据的第一时频资源的标识和传输数据的第二时频资源的标识。从而，使得终端设备根据时频资源的标识确定传输数据的时频资源，在指定的第一时频资源和第二时频资源上发送或接收数据，从而，降低了指示信息的开销，提高了系统资源利用率。

移动通信技术已经深刻地改变了人们的生活，但人们对更高性能的移动通信技术的追求从未停止。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。5G移动通信系统又称为新无线接入技术(new radio access technology，NR)系统。国际电信联盟(international telecommunication union，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)、URLLC、海量机器类通信(massive machine type communications，mMTC)、多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)和定位业务等。部署场景包括室内热点(Indoor hotspot)、密集城区(Dense Urban)、郊区、城区宏覆盖(Urban Macro)及高铁场景等。
典型的eMBB业务包括超高清视频、增强现实(augmented reality，AR)和虚拟现实(virtual reality，VR)等。这些业务的主要特点包括传输数据量大和传输速率很高。
典型的mMTC业务包括智能电网配电自动化和智慧城市等。这些业务的主要特点包括联网设备数量巨大、传输数据量较小和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。
典型的URLLC业务包括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和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、传输数据量较少和具有突发性。例如，车对外界的信息交换(vehicle to everything，V2X)需要的可靠性为99.999％，端到端时延为5毫秒(millisecond，ms)；配电(power distribution)需要可靠性为99.9999％，端到端时延为5ms；工厂自动化(factory automation)可靠性为99.9999％，端到端时延为2ms。
在长期演进(long term evolution，LTE)系统中，最小的时间调度单元为一个1ms时间长度的传输时间间隔(transmission time interval，TTI)。5G既支持时间单元级别的时域调度粒度，也可以支持微时间单元的时域调度粒度，以及满足不同业务的时延需求。例如，时间单元主要用于eMBB业务，微时间单元主要用于URLLC业务。需要说明的是，上述时间单元和微时间单元是一般性的说法，具体的一个例子可以为，时间单元可以称为时隙，微时间单元可以称为微时隙、非时隙(non-slot-based)、迷你时隙(mini-slot)或符号(symbol)；或者，时间单元可以称为子帧，微时间单元可以称为微子帧；其他类似的时域资源划分方式都不做限定。其中，一个时隙比如可以包括14个时域符号，一个迷你时隙包括的时域符号数小于14，比如2、3、4、5、6或7等等；或者，一个时隙比如可以包括7个时域符号，一个迷你时隙包括的时域符号数小于7，比如2或4等等，具体取值也不做限定。这里的时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。

接下来，对资源指示的方法进行详细说明。在第一种可能的实现方式中，可以通过指示信息指示第一时频资源，网络设备或终端设备在指示的第一时频资源上接收或发送数据。图4为本申请实施例提供的一种资源指示的方法流程图。如图4所示，该方法可以包括：
S401、网络设备向终端设备发送第一指示信息，所述第一指示信息用于指示N个第一时频资源中的M个第一时频资源。
在一些实施例中，网络设备可以通过高层信令向终端设备发送第一指示信息。高层信令可以是指高层协议层发出的信令。高层协议层为物理层以上的至少一个协议层。高层协议层可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)。
例如，网络设备可以通过RRC信令向终端设备发送第一指示信息。或者，可替换描述为：网络设备向终端设备发送RRC信令，该RRC信令包括第一指示信息。
在一些实施例中，网络设备可以通过物理层信令向终端设备发送第一指示信息。如下行控制信令(dynamic control indication，DCI)。
第一指示信息用于指示N个第一时频资源中的M个第一时频资源，其中，N和M均为正整数，M个第一时频资源中的每个第一时频资源用于传输数据。
在一种可能的设计中，第一指示信息可以是比特序列，通过比特序列指示N个第一时频资源中的M个第一时频资源。例如，第一指示信息可以是位图，该位图可以包括N个比特位。若N个比特位中的M个比特位的比特为1，可以表示M个比特位指示的第一时频资源中的每个第一时频资源用于传输数据，N个比特位中的N-M个比特位的比特为0，可以表示N-M个比特位指示的第一时频资源中的每个第一时频资源不用于传输数据。若N个比特位中的M个比特位的比特为0，可以表示M个比特位指示的第一时频资源中的每个第一时频资源用于传输数据，N个比特位中的N-M个比特位的比特为1，可以表示N-M个比特位指示的第一时频资源中的每个第一时频资源不用于传输数据。或者，在第一信息中还指示N的值。
可选的，不用于传输数据的第一时频资源可以传输其他业务信息或其他用户的业务信息，对此，本申请不予限定。
S402、所述终端设备接收所述网络设备发送的所述第一指示信息。
该第一指示信息用于指示N个第一时频资源中的M个第一时频资源，M个第一时频资源中的每个第一时频资源用于传输数据。关于第一指示信息的详细解释可以参考S401的阐述，不予赘述。
在一些实施例中，网络设备向终端设备发送数据时，可以在第一指示信息指示的第一时频资源上发送该数据，其中，所述数据可以是下行数据，第一时频资源可以是PDSCH。具体的，网络设备向终端设备发送数据的详细解释参考S403和S404的阐述。
S403、所述网络设备以所述N个第一时频资源为周期，在所述N个第一时频资源中的M个第一时频资源上向所述终端设备发送数据。
需要特别强调的是，本申请中，在N个第一时频资源中的M个第一时频资源上向终端设备发送的数据可以是M个数据。所述M个数据中的每个数据可以是1个数据传输块(transmit block，TB)，也可以是1组数据传输块，所述1组数据传输块可以是一个传输块的多次重复，也可以是多个传输块，后续不再赘述。
在一些实施例中，从第一起始时刻开始，以N个第一时频资源为资源循环周期，在每个资源循环周期内的M个第一时频资源上发送数据。第一起始时刻为发送第一时频资源的起始时刻。在第一时频资源上发送的每个数据信息可以相同，也可以不同，不予限定。
S404、所述终端设备以所述N个第一时频资源为周期，在所述N个第一时频资源中的M个第一时频资源上接收所述网络设备发送的数据。
在一些实施例中，终端设备可以根据第一起始时刻和第一周期确定发送第一时频资源的时刻，第一起始时刻为发送第一时频资源的起始时刻，第一周期为发送第一时频资源的周期。在终端设备接收到第一指示信息后，从第一起始时刻开始，以N个第一时频资源为资源循环周期，在每个资源循环周期内的M个第一时频资源上接收数据。在第一时频资源上接收到的数据可以是M个数据，所述M个数据可以相同，也可不同。所述M个数据中的每个数据可以是1个TB，也可以是1组数据传输块，所述1组数据传输块可以是一个传输块的多次重复，也可以是多个传输块，后续不再赘述。
在另一些实施例中，终端设备向网络设备发送数据时，可以在第一指示信息指示的第一时频资源上发送该数据，其中，所述数据可以是上行数据，第一时频资源可以是PUSCH。具体的，终端设备向网络设备发送数据的详细解释参考S405和S406的阐述。
S405、所述终端设备以所述N个第一时频资源为周期，在所述N个第一时频资源中的M个第一时频资源上向所述网络设备发送数据。
在一些实施例中，在终端设备接收到第一指示信息后，从第一起始时刻开始，以N个第一时频资源为资源循环周期，在每个资源循环周期内的M个第一时频资源上发送数据。
S406、所述网络设备以所述N个第一时频资源为周期，在所述N个第一时频资源中的M个第一时频资源上接收所述终端设备发送的数据。
在一些实施例中，从第一起始时刻开始，以N个第一时频资源为资源循环周期，在每个资源循环周期内的M个第一时频资源上接收M个数据。
本申请实施例提供的资源指示的方法，通过指示发送数据的第一时频资源，使得 网络设备和终端设备可以在指定的第一时频资源上接收或发送数据，从而，有效地提高了配置资源的利用率。
另外，由于第一时频资源是半静态资源，接收端(网络设备或终端设备)可以对第一时频资源进行盲检测接收数据。如果接收端对配置的所有第一时频资源进行盲检测，有些第一时频资源上未承载数据，会导致浪费了接收端的功耗。本申请实施例提供资源指示的方法，接收端对第一指示信息指示的第一时频资源进行盲检测接收数据，避免了对配置的所有第一时频资源进行盲检测，不仅有效地提高了时频资源的利用率，还节省了接收端的功耗。本申请实施例提供如何确定资源分配的方法，在满足数据传输时延的前提下，选取最小的资源循环周期和最少的资源使用个数，从而降低了指示信息的开销，提高了系统资源利用率。并且，采用本申请实施例所提供的方法，能够使业务和资源周期更好的匹配，避免接收端和发送端对可用资源的理解产生偏差，从而保证业务的时延和可靠性。
在一些实施例中，N和M可以是网络设备根据第一起始时刻、第一周期、第二起始时刻和第二周期确定的。第二起始时刻为数据的业务周期的起始时刻。第二周期为数据的业务周期。由于在业务到达后，若业务到达的时刻与发送第一时频资源的时刻不同，则等到发送第一时频资源的时刻后发送数据。为了保证发送数据的时延，避免发生某次业务还没有发送，下一次业务已到达的情况，应设置第一周期小于第二周期。如图5所示，在发送第一指示信息，即S401之前，执行S501。
S501、所述网络设备根据第一起始时刻、第一周期、第二起始时刻和第二周期确定第一时频资源的个数N中的M个第一时频资源。
由于业务到达的时刻和第一时频资源的发送时刻均是周期性出现的，因而业务到达的时刻和第一时频资源的发送时刻之间的差值也呈现出周期规律。在一些实施例中，网络设备可以根据第一周期和第二周期确定N和M的具体数值。N和M满足如下公式(1)。
P_tr*M＝P_re*N   (1)
其中，P_tr表示第二周期，P_re表示第一周期。
进一步的，在网络设备确定了N和M的具体数值后，确定N个第一时频资源中传输数据的M个第一时频资源。假设第二起始时刻为数据的业务周期的起始时刻，第二起始时刻与第一起始时刻相同，即第一次业务到达的时刻与第一次发送第一时频资源的时刻相同，可以将第一起始时刻对应的第一时频资源确定为传输数据的第一时频资源，然后，将与业务到达的时刻最近的第一时频资源的时刻对应的第一时频资源确定为传输数据的第一时频资源，以此类推，从而确定N第一时频资源中的M个第一时频资源。
可选的，可以预先为网络设备和终端设备配置第二周期。因此，网络设备无需从其他网元获取第二周期。或通过终端设备和网络设备之间的信息交互，在传输数据前获取第二周期。
下面以第二周期为0.833ms为例，对确定第一时频资源的个数N中的M个第一时频资源进行说明。为了保证发送数据的时延，则在小于0.833ms的第一时频资源中寻找合适的第一时频资源。例如，对于子载波间隔为15kHz的一个时隙，2个符号的时 间长度为1/7ms，7个符号的时间长度为0.5ms，14个符号的时间长度为1ms，因此，第一周期的取值可以是0.5ms或1/7ms。
当第一周期为0.5ms，且第二周期为0.833ms时，将0.5ms和0.833ms代入公式(1)，即P_re＝0.5ms＝1/2ms，P_tr＝0.833ms＝5/6ms，选择5/6*M＝1/2*N成立的最小的M和N，则M＝3，N＝5。M和N满足互质的关系。
当第一周期为1/7ms，且第二周期为0.833ms时，将1/7ms和0.833ms代入公式(1)，即P_re＝1/7ms，P_tr＝0.833ms＝5/6ms，选择5/6*M＝1/7*N成立的最小的M和N，则M＝6，N＝35。M和N满足互质的关系。
从而，在保证数据传输时延的前提下，选择资源循环周期最短的M和N，或进一步考虑资源循环周期内配置资源数最少的M和N，则可以确定M＝3，N＝5，第一周期为0.5ms。如图6所示，发送数据的示意图。发送第一时频资源的时刻可以是0、0.5、1、1.5、2和2.5等。图中画“×”的时刻对应的第一时域资源上不会传输数据。
如表1所示，为发送数据的具体时刻。
表1
业务序号 业务到达(ms) 发送第一时域资源的时刻(ms) 时延(ms)
0 0 0 0
1 0.833333 1 0.166667
2 1.666667 2 0.333333
3 2.5 2.5 0
4 3.333333 3.5 0.166667
5 4.166667 4.5 0.333333
6 5 5 0
7 5.833333 6 0.166667
8 6.666667 7 0.333333
9 7.5 7.5 0
10 8.333333 8.5 0.166667
11 9.166667 9.5 0.333333
由图6和表1可知，业务序号0表示第1次数据到达，第1次数据到达的到达时刻为0ms，发送第一时域资源的时刻为0ms，第1次发送数据的时刻为0ms。业务序号1表示第2次数据到达，第2次数据到达的到达时刻为0.833333ms，发送第一时域资源的时刻为1ms，第2次传输数据的时刻为1ms。时延为0.166667。业务序号2表示第3次数据到达，第3次数据到达的到达时刻为1.666667ms，发送第一时域资源的时刻为2ms，第3次传输数据的时刻为2ms。时延为0.333333。在对应0.5ms的第一时频资源和1.5ms的第一时频资源上未发送数据，依次循环。
因此，每5个第一时频资源为一个资源循环周期。对于每个资源循环周期，在第一个第一时频资源、第三个第一时频资源和第五个第一时频资源上发送或接收数据， 第二个第一时频资源和第四个第一时频资源上不发送数据。
从而，第一指示信息可以指示5个第一时频资源中的3个第一时频资源。若第一指示信息是位图，该位图为10101。或在第一信息中还指示N的值。
示例的，假设第二周期为16.67ms＝100/6ms，选择第一周期小于第二周期的值，如5ms、8ms或10ms，根据公式(1)可以得到如表2中所示的M和N的取值。最后可以确定选取最小的组合M＝3，N＝5
表2
第一周期 M N
10 3 5
8 12 25
5 3 10
从而，在保证数据传输时延的前提下，选择资源循环周期最短的M和N，或进一步考虑资源循环周期内配置资源数最少的M和N，则可以确定M＝3，N＝5，第一周期为10ms。第一指示信息可以指示5个第一时频资源中的3个第一时频资源。每5个第一时频资源为一个资源循环周期。对于每个资源循环周期，在第二个第一时频资源、第四个第一时频资源和第五个第一时频资源上发送或接收数据，第一个第一时频资源和第三个第一时频资源上不发送数据。若第一指示信息是位图，该位图为01011。或在第一信息中还指示N的值为5。
进一步的，在网络设备向终端设备发送第一指示信息之前，网络设备可以为终端设备配置第一时频资源，以便于终端设备在第一时频资源上接收或发送数据。如图5所示，在S501之前，执行S502～S503。
S502、所述网络设备向所述终端设备发送第一资源配置信息。
在一些实施例中，网络设备可以通过高层信令向终端设备发送第一资源配置信息。例如，网络设备可以通过RRC信令向终端设备发送第一资源配置信息。例如，RRC信令中的高层参数configuredGrantConfig，configuredGrantConfig包含了rrc-ConfiguredUplinkGrant。第一资源配置信息为rrc-ConfiguredUplinkGrant。第一资源配置信息包含第一起始时刻和第一周期。
S503、所述终端设备接收所述网络设备发送的所述第一资源配置信息。
在一些实施例中，终端设备接收到第一资源配置信息后，可以在周期配置的第一时频资源上发送或接收数据。在另一些实施例中，终端设备接收到第一资源配置信息后，再接收到下行控制信息(downlink control information，DCI)后，激活第一资源配置信息配置的第一时频资源，在周期配置的第一时频资源上发送或接收数据。第一资源配置信息包含第一起始时刻和第一周期。关于第一资源配置信息的具体解释可以参考S502的阐述，不用赘述。
在另一些实施例中，网络设备可以为终端设备配置多套时频资源，在多套时频资源上接收数据。如图7所示，所述方法还包括。
S701、网络设备向终端设备发送第二资源配置信息。
在一些实施例中，网络设备可以通过高层信令向终端设备发送第二资源配置信息。 例如，网络设备可以通过RRC信令向终端设备发送第二资源配置信息。例如，RRC信令中的高层参数configuredGrantConfig，configuredGrantConfig包含了第二资源配置信息(如rrc-ConfiguredUplinkGran)。第二资源配置信息包含第三起始时刻和第三周期，第三起始时刻为发送第二时频资源的起始时刻，第三周期为发送第二时频资源的周期。
S702、所述终端设备接收所述网络设备发送的所述第二资源配置信息。
在一些实施例中，终端设备接收到第二资源配置信息后，可以在周期配置的第二时频资源上发送或接收数据。在另一些实施例中，终端设备接收到第二资源配置信息后，在接收到DCI后，激活第二资源配置信息配置的第二时频资源，在周期配置的第二时频资源上发送或接收数据。第二资源配置信息包含第三起始时刻和第三周期。关于第二资源配置信息的具体解释可以参考S701的阐述，不用赘述。
需要说明的是，本申请实施例提供的资源指示的方法步骤的先后顺序可以进行适当调整。示例的，如S502和S701之间的前后顺序可以互换，即网络设备可以先向终端设备发送第二资源配置信息，再向终端设备发送第一资源配置信息，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本申请的保护范围之内，因此不再赘述。
在一些实施例中，网络设备还可以确定第二时频资源的个数K中的L个第二时频资源，即确定第二时频资源的资源循环周期。如图7所示，在发送第一指示信息，即S401之前，执行S703。
S703、所述网络设备根据第三起始时刻、第三周期、第二起始时刻和第二周期确定第二时频资源的个数K中的L个第二时频资源。
由于业务到达的时刻和第二时频资源的发送时刻均是周期性出现的，因而业务到达的时刻和第二时频资源的发送时刻之间的差值也呈现出周期规律。在一些实施例中，网络设备可以根据第三起始时刻、第三周期、第二起始时刻和第二周期确定K和L，其中，K和L均为正整数，K和L满足公式(1)。具体的可以参考S501的阐述，不予赘述。
从而，第一指示还用于指示K个第二时频资源中的L个第二时频资源。L个第二时频资源中的每个第二时频资源用于传输数据。
在一些实施例中，网络设备向终端设备发送数据时，可以在第一指示信息指示的第二时频资源上发送该数据，其中，所述数据可以是下行数据，第二时频资源可以是PDSCH。具体的，网络设备向终端设备发送数据的详细解释参考执行S704和S705阐述。
S704、所述网络设备以K个所述第二时频资源为周期，在所述K个第二时频资源中的L个所述第二时频资源上向所述终端设备发送数据。
在一些实施例中，从第三起始时刻开始，以K个第二时频资源为资源循环周期，在每个资源循环周期内的L个第二时频资源上发送数据。在第二时频资源上发送数据可以为一个或多个，多个数据中每个数据可以相同，也可以不同，不予限定。
S705、所述终端设备以所述K个第二时频资源为周期，在所述K个第二时频资源中的L个第二时频资源上接收网络设备发送的数据。
在一些实施例中，终端设备可以根据第三起始时刻和第三周期确定发送第二时频资源的时刻。在终端设备接收到第一指示信息后，从第三起始时刻开始，以K个第二时频资源为资源循环周期，在每个资源循环周期内的L个第二时频资源上接收M个数据。在第二时频资源上接收到的数据可以是一个或多个，多个数据中每个数据可以相同，也可以不同，不予限定。
在另一些实施例中，终端设备向网络设备发送数据时，可以在第一指示信息指示的第二时频资源上发送数据，其中，数据可以是上行数据，第二时频资源可以是PUSCH。具体的，终端设备向网络设备发送数据的详细解释参考执行S706和S707的阐述。
S706、所述终端设备以所述K个第二时频资源为周期，在所述K个第二时频资源中的L个第二时频资源上向网络设备发送数据。
在一些实施例中，在终端设备接收到第一指示信息后，从第三起始时刻开始，以K个第二时频资源为资源循环周期，在每个资源循环周期内的L个第二时频资源上发送L个数据。
S707、网络设备以K个第二时频资源为周期，在K个第二时频资源中的L个第二时频资源上接收终端设备发送的数据。
在一些实施例中，从第三起始时刻开始，以K个第二时频资源为资源循环周期，在每个资源循环周期内的L个第二时频资源上接收L个数据。
在一种可能的设计中，第一指示信息是位图，该位图包括N+K个比特位。N个比特位中的M个比特位的比特指示发送或接收数据的第一时频资源。K个比特位中的L个比特位的比特指示发送或接收数据的第二时频资源。或在第一信息中还指示N的值。
例如，若K个比特位中的L个比特位的比特为1，可以表示L个比特位指示的第二时频资源中的每个第二时频资源用于传输数据，K个比特位中的K-L个比特位的比特为0，可以表示K-L个比特位指示的第二时频资源中的每个第二时频资源不用于传输数据。若K个比特位中的L个比特位的比特为0，可以表示L个比特位指示的第二时频资源中的每个第二时频资源用于传输数据，K个比特位中的K-L个比特位的比特为1，可以表示K-L个比特位指示的第二时频资源中的每个第二时频资源不用于传输数据。
可理解，M+L个数据为业务循环周期。每个业务循环周期内，在M个第一时频资源上接收数据(例如M个数据)，在L个第二时频资源上接收数据(例如L个数据)。
示例的，如图8所示，发送数据的示意图。第一起始时刻为0ms，第一周期为1ms，发送第一时频资源的时刻可以是整数毫秒，如：0、1、2和3等。第三起始时刻为0.5ms，第三周期为1ms，发送第二时频资源的时刻可以是半整数毫秒，如：0.5、1.5和2.5等。发送第一时频资源的时刻与发送第二时频资源的时刻相差0.5ms。第二周期为0.833ms。图中画“×”的时刻对应的第一时域资源上不会传输数据。
由图8和表1可知，业务序号0表示第1次数据到达，第1次数据到达的到达时刻为0ms，发送第一时域资源的时刻为0ms，第1次发送数据的时刻为0ms。
业务序号1表示第2次数据到达，第2次数据到达的到达时刻为0.833333ms，发送第一时域资源的时刻为1ms，第2次传输数据的时刻为1ms。时延为0.166667。
业务序号2表示第3次数据到达，第3次数据到达的到达时刻为1.666667ms，发 送第一时域资源的时刻为2ms，第3次传输数据的时刻为2ms。时延为0.333333。在对应3ms的第一时频资源和4ms的第一时频资源上未发送数据。
业务序号3表示第4次数据到达，第4次数据到达的到达时刻为2.5ms，发送第一时域资源的时刻为2.5ms，第4次发送数据的时刻为2.5ms。
业务序号4表示第5次数据到达，第5次数据到达的到达时刻为3.333333ms，发送第一时域资源的时刻为3.5ms，第5次传输数据的时刻为3.5ms。时延为0.166667。
业务序号5表示第6次数据到达，第6次数据到达的到达时刻为4.166667ms，发送第一时域资源的时刻为4.5ms，第6次传输数据的时刻为4.5ms。时延为0.333333。在对应0.5ms的第一时频资源和1.5ms的第一时频资源上未发送数据。依次循环。
因此，每5个第一时频资源为一个第一资源循环周期。对于每个第一资源循环周期，在第一个第一时频资源、第二个第一时频资源和第三个第一时频资源上发送或接收数据，第四个第一时频资源和第五个第一时频资源上不发送数据。每5个第二时频资源为一个第二资源循环周期。对于每个第二资源循环周期，在第三个第一时频资源、第四个第一时频资源和第五个第一时频资源上发送或接收数据，第一个第一时频资源和第二个第一时频资源上不发送数据。
从而，第一指示信息可以指示5个第一时频资源中的3个第一时频资源和5个第二时频资源中的3个第二时频资源。该位图为1110000111。或在第一信息中还指示N的值为10。
在另一种可能的设计中，第一指示信息包括传输M个数据的第一时频资源的标识和传输L个数据的第二时频资源的标识。
应理解，所述“传输”可以是指发送或接收。M+L个数据为业务循环周期。每个业务循环周期内，在M个第一时频资源上接收M个数据，在L个第二时频资源上接收L个数据。
假设第一时频资源的标识为1，第二时频资源的标识为2。由图8和表1可知，第一指示信息可以指示3个第一时频资源的标识和3个第二时频资源的标识，即1,1,1,2,2,2。
示例的，数据的第一个到达时刻为0ms，第一起始时刻为0ms，传输第1次数据采用第一时频资源，因此，连续传输3次数据，即传输第1、2和3次数据采用第一时频资源，第4次数据的到达时刻为2.5ms，在传输第3次数据的2ms之后，2.5ms是传输数据的第一个时机，因此，在第二时频资源上发送3次数据，即传输第4、5和6次数据采用第二时频资源。依次类推传输数据。
在第二种可能的实现方式中，在网络设备或终端设备发送或接收数据前，可以先自主确定发送或接收数据的第一时频资源。图9为本申请实施例提供的一种资源指示的方法流程图。如图9所示，该方法可以包括：
S901、网络设备向终端设备发送第一资源配置信息。第一资源配置信息包含第一周期。
第一周期为发送第一时频资源的周期。在一些实施例中，网络设备可以通过高层信令向终端设备发送第一资源配置信息。关于发送第一资源配置信息的具体解释可以参考S502的阐述，不予赘述。
S902、所述终端设备接收所述网络设备发送的所述第一资源配置信息。
第一资源配置信息包含第一周期，关于接收第一资源配置信息的具体解释可以参考S503的阐述，不用赘述。
在一些实施例中，网络设备向终端设备发送数据前，可以先确定发送数据的第一时频资源，其中，数据可以是下行数据，第一时频资源可以是PDSCH。执行S903和S906。
S903、所述网络设备根据所述第一周期、第二周期、第i-1时刻和第j-1时刻确定第j时刻。
第二周期为数据的业务周期，第二周期大于第一周期。第i-1时刻为数据的第i-1个业务周期的起始时刻，第j-1时刻为第i-1次传输数据的第一时频资源的起始时刻，第j时刻为第i次传输数据的第一时频资源的起始时刻，i和j均为正整数。
在一种可能的设计中，可以对每个第一时频资源进行检测，确定出可以发送数据的第一时频资源。在一些实施例中，网络设备可以先根据第i-1时刻和第j-1时刻确定第一数值，第一数值为第j-1时刻与第i-1时刻的差值，或者，第一数值为第j-1时刻和第i-1时刻的差值的绝对值。然后，根据第一周期、第一数值和第二周期确定n，n为正整数，n为第一周期的个数，第一周期的个数满足第一条件的最小值，第一条件为第一周期与第一数值之和大于第二周期。将n个第一周期与第一数值之和确定为第j时刻。第j时刻满足公式(2)。
T j＝n*c 1+|t i-1-T i-1|＞c 2   (2)
其中，T j表示第j时刻，c 1表示第一周期，n表示第一周期的个数，t i-1表示第i-1时刻，T i-1表示第i-1时刻，c 2表示第二周期。
在另一种可能的设计中，网络设备可以根据业务周期的起始时刻(或业务的到达时刻)确定发送数据的第一时频资源的时刻。
在一些实施例中，网络设备可以先根据第j-1时刻、第一周期和第i时刻确定n，n为正整数，n为第一周期的个数，第一周期的个数满足第一条件的最小值，第一条件为第一周期与第j-1时刻之和大于第i时刻，第i时刻为数据的第i个业务周期的起始时刻，第i-1时刻和第二周期之和等于第i时刻。然后，根据n个第一周期与第j-1时刻确定第j时刻，第j时刻为大于第i时刻的第一时频资源的起始时刻中的最小值。
第j时刻满足公式(3)。
T j＝T j-1+n*c 1＞t i   (3)
其中，T j表示第j时刻，c 1表示第一周期，n表示第一周期的个数，t i表示第i时刻，T j-1表示第j-1时刻。
S904、所述网络设备在所述第j时刻的第一时频资源上向所述终端设备发送数据。
从而，网络设备在确定的第一时频资源上发送数据，未发送数据的第一时频资源可以发送其他信息，有效地提高了配置资源的利用率。
S905、所述终端设备根据所述第一周期、所述第二周期、所述第i-1时刻和所述第j-1时刻确定第j时刻。
在一种可能的设计中，可以对每个第一时频资源进行检测，确定出可以发送数据的第一时频资源。在另一种可能的设计中，网络设备可以根据业务周期的起始时刻(或 业务的到达时刻)确定发送数据的第一时频资源的时刻。具体的参考S903的阐述，不予赘述。
S906、所述终端设备在所述第j时刻的所述第一时频资源上接收所述网络设备发送的数据。
从而，终端设备在确定的第一时频资源上接收数据，未接收数据的第一时频资源可以接收其他信息，有效地提高了配置资源的利用率。同时，避免了对配置的所有第一时频资源进行盲检测，对确定的第一时频资源进行盲检测，节省了终端设备的功耗。
在另一些实施例中，终端设备向网络设备发送数据前，可以先确定发送数据的第一时频资源，其中，数据可以是上行数据，第一时频资源可以是PUSCH。执行S907和S910。
S907、所述终端设备根据所述第一周期所述、第二周期、所述第i-1时刻和所述第j-1时刻确定第j时刻。
S908、所述终端设备在所述第j时刻的所述第一时频资源上向所述网络设备发送数据。
S909、所述网络设备根据所述第一周期、所述第二周期、所述第i-1时刻和所述第j-1时刻确定所述第j时刻。
S910、所述网络设备在所述第j时刻的所述第一时频资源上接收所述终端设备发送的数据。
S907和S910具体的解释可以参考S903和S906的阐述，不予赘述。
另外，若数据的第1个业务周期的起始时刻与第1次传输数据的第一时频资源的起始时刻存在偏差，可能导致传输数据可能存在误差，接收端无法准确地接收数据。如表3所示。

如表3所示，“发送时刻”表示根据本申请实施例所述的资源指示的方法确定的传输数据的时刻。“*业务到达”表示实际传输数据的时刻。
在一些实施例中，终端设备可以向网络设备发送第二数值，第二数值用于指示数据的第p个业务周期的起始时刻与传输第q个数据的第一时频资源的起始时刻的差值，或者，数据的第p个业务周期的起始时刻与传输第q个数据的第一时频资源的起始时刻的差值的绝对值。p和q为正整数，如p＝1，q＝1。
第1次传输数据的第一时频资源的起始时刻可以是第一起始时刻，第一起始时刻为发送第一时频资源的起始时刻。终端设备可以接收网络设备发送的第一资源配置信息获取第一起始时刻。
