Description

数据发送和接收方法以及装置 技术领域
本发明实施例涉及通信技术领域，特别涉及一种数据发送和接收方法以及装置。
背景技术
近年来，无线通信技术得到了高速发展，第三代合作伙伴计划(3GPP，The 3rd Generation Partnership Project)标准化已经发展到Rel.15(版本15)。从Rel.13开始，基于进一步扩大容量的考虑，长期演进(LTE，Long Term Evolution)技术开始了利用非授权频段传输的研究。为了保证对非授权频段利用的公平性以及干扰控制，引入了先听后说(LBT，Listen Before Talk)机制，即非授权接入设备在准备发射数据前先监听目标频段是否正在被其他传输数据占用。
LTE标准中提供了两种类型的LBT方式：
第一种LBT类型，设备首先探测信道(或频段)是否在一段时间内为空闲状态，当判断为空闲状态后，该设备仍需检测一个竞争窗的时间；若在竞争窗内该信道仍为空闲，该设备将利用该信道发送数据；
第二种LBT类型，设备持续监听信道(或频段)25微秒，若判断为空闲则直接利用该信道发送数据。当该设备接入非授权频段后，占用时间不得超过最大信道占用时间(MCOT，Maximum Channel Occupancy Time)。

以下通过示例对本发明实施例的场景进行说明，但本发明不限于此。
图1是本发明实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102。为简单起见，图1仅以一个终端设备和一个网络设备为例进行说明，但本发明实施例不限于此。
在本发明实施例中，网络设备101和终端设备102之间可以进行现有的业务或者未来可实施的业务。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
LTE技术在Rel.14中引入了在非授权频段上的上行传输机制，并且引入了4种新的下行控制信息(DCI，Downlink Control Information)格式用于在非授权频段的上行调度指示；它们分别是DCI format 0A/4A/0B/4B。其中，0A/0B格式调度的是单天线端口传输方式，4A/4B格式调度的是多天线端口传输方式；并且0A/4A格式调度的是单个子帧的物理上行共享信道(PUSCH，Physical Uplink Shared Channel)传输方式，而0B/4B格式调度的是连续多个子帧的PUSCH传输方式。
调度信令包含一个‘PUSCH trigger A’域，该域用于指示本次调度是否是触发调度。例如，置‘0’表示不是触发调度(非触发调度)，那么在接收到该调度信令后，终端设备根据该调度信令中‘Timing offset’域所指示的时序发送PUSCH；置‘1’表示是本次调度为触发调度，终端设备需要等待接收由CC-RNTI加扰的DCI format 1C信令(触发信令)，若接收到的该触发信令中‘PUSCH trigger B’域被置为‘1’，表示上行调度被触发，终端设备将结合调度信令(DCI format 0A/4A/0B/4B)中的‘Timing offset’域与触发信令(DCI format 1C)中的‘UL duration and offset’域所指示的时序，确定发送PUSCH的子帧。
图2是非触发调度方式的示意图。如图2所示，在LTE中从上行调度信令到调度的PUSCH发送的最小时间间隔为4个子帧。该调度时间限制制约了上行调度的灵活性。例如，在同帧内调度的情况下，前四个子帧将不能被调度传输上行数据；特别是在非授权频段中，设备接入信道后不能调度邻近子帧而会造成资源浪费及时间延迟。因此，LTE中增加了触发调度方式，提前发送调度信令。
图3是触发调度方式的示意图。如图3所示，网络设备可以提前向终端设备发送调度信令；当网络设备接入信道后，向终端设备发送触发信令以触发上行数据的发送，这增加了上行调度的灵活性。
另外，为了满足OCB/PSD需求，eLAA中采用Interlace作为上行传输资源分配的基本单位；一个interlace由10个资源块(RB，Resource Block)组成，且这10个 RBs等间距地分布在20MHz带宽中。例如，Interlace 0由RB0、RB10、RB20、…RB90组成。网络设备将通过上行调度信令分配一个或多个interlace给终端设备，用于终端设备进行上行数据传输。
基于新无线(NR，New Radio)的非授权频段物理层接入技术从RAN1#92次会议开始讨论，并且明确指出需要讨论NR宽带(wideband，频域带宽大于20MHz)传输技术在非授权频段的应用，且规定在不能保证没有其他传输技术共存的情况下，NR非授权频带的传输带宽大小应为20MHz的整数倍。因为其他非授权频段传输技术，例如WiFi的传输带宽也是以20MHz为单位的。
然而，在宽带传输情况下，如果网络设备调度了宽带资源来传输数据，但LBT监听结果中仅部分带宽资源为空闲状态时，是否进行数据传输成为了待解决问题。若放弃传输数据，将造成空闲状态带宽上的资源浪费，且需要等待整个宽带资源为空闲状态时才能够发送数据，从而引起传输时延。若仅在空闲状态的带宽资源上传输数据，如果是下行传输，则调度信令中调度带宽资源的相关信息将没有时间进行修改重组，实际传输带宽与调度带宽不一致将造成接收端数据解码失败；如果是上行传输，只在空闲状态的带宽传输将与上行调度信令的指示不一致。
因此，需要对在非授权频段上的传输调度指示进行研究，以提高频谱资源利用效率、减少传输时延，并保证调度的灵活性。
值得注意的是，本发明实施例以非授权频段和LBT为例进行说明，但本发明不限于此，本发明也同样适用于存在类似问题的其他场景中。
实施例1
本发明实施例提供一种数据接收方法，从网络设备侧进行说明。本实施例和实施例2可以称为触发调度方式。
图4是本发明实施例的数据接收方法的一示意图，如图4所示，该数据接收方法包括：
步骤401，网络设备向终端设备发送数据调度控制信息，用于指示所述终端设备发送上行数据的相关信息；
步骤402所述网络设备向所述终端设备发送用于指示一个或多个频域带宽资源的第一指示信息；以及
步骤403，所述网络设备接收所述终端设备发送的所述上行数据。
在本实施例中，所述频域带宽资源为具有一定频带宽度的频域资源。
在本实施例中，所述网络设备在非授权频段上接收所述上行数据；所述网络设备在非授权频段或者授权频段上发送所述第一指示信息(或者也可以称为频域带宽资源指示或者传输带宽指示)和/或所述数据调度控制信息。
在本实施例中，所述网络设备检测非授权频段的信道以确定所述一个或多个频域带宽资源；其中，所述第一指示信息还可以用于指示所述一个或多个频域带宽资源为如下至少之一：所述终端设备能够发送上行数据的带宽资源，所述网络设备发送下行数据的带宽资源，所述终端设备能够共享所述网络设备的信道占用时间发送上行数据的带宽资源。
终端设备可以接收数据调度控制信息(例如也可以称为调度信令、上行调度信令或者数据调度信令)，数据调度控制信息中还包括用于指示终端设备在调度带宽资源上可以用于发送上行数据的可用时频资源的指示信息(也可称为可用时频资源信息，例如包括可用资源块的索引，等等)。并且通过一个承载了频域带宽资源指示的触发信息(例如也可以称为触发信令、数据触发信令或者上行数据触发信令)，终端设备可以被触发进行上行数据传输，然后在数据调度控制信息指示的可用时频资源和、第一指示信息指示的一个或多个频域带宽资源重合(或重叠)的带宽中的可用时频资源上发送上行数据。
如果数据调度控制信息指示的可用时频资源和、第一指示信息指示的一个或多个频域带宽资源没有重合的资源，那么终端设备将不发送该数据调度控制信息(或者调度信令)所调度的上行数据，或者，在接收到一个与该数据调度控制信息(或者调度信令)指示的可用时频资源有重合资源的第一指示信息后，在重合资源上发送上行数据。
由此，网络设备向终端设备发送用于指示一个或多个频域带宽资源的第一指示信息，网络设备和终端设备能够对实际使用的频域带宽资源达成一致，从而能够提高频谱资源利用效率、减少传输时延，并保证调度的灵活性。
在一个实施方式中，所述第一指示信息在所述数据调度控制信息之后发送。但本发明不限于此，如后面实施例所述，所述第一指示信息也可以在所述数据调度控制信息之前发送，或者所述第一指示信息与所述数据调度控制信息的发送也可以没有特定 的时序关系。
在一个实施方式中，所述第一指示信息包括在承载了上行数据触发信息的第一控制信息中；所述上行数据触发信息用于触发所述终端设备发送所述上行数据。
图5是本发明实施例的数据发送和接收方法的一示意图，如图5所示，该数据发送和接收方法包括：
步骤501，网络设备向终端设备发送数据调度控制信息，用于指示所述终端设备发送上行数据的相关信息；
步骤502，网络设备检测非授权频段的信道以确定一个或多个频域带宽资源；
步骤503，所述网络设备向所述终端设备发送包括上行数据触发信息的第一控制信息，该第一控制信息包括用于指示一个或多个频域带宽资源的第一指示信息；
步骤504，所述终端设备在所述数据调度控制信息指示的可用时频资源和所述第一指示信息指示的一个或多个频域带宽资源重合的带宽中的可用时频资源上，向所述网络设备发送上行数据。
值得注意的是，以上附图5仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5的记载。
在一个实施方式中，所述第一指示信息包括在不同于所述第一控制信息的第二控制信息中。
图6是本发明实施例的数据发送和接收方法的另一示意图，如图6所示，该数据发送和接收方法包括：
步骤601，网络设备向终端设备发送数据调度控制信息，用于指示所述终端设备发送上行数据的相关信息；
步骤602，网络设备检测非授权频段的信道以确定一个或多个频域带宽资源；
步骤603，所述网络设备向所述终端设备发送第二控制信息，该第二控制信息包括用于指示一个或多个频域带宽资源的第一指示信息；
步骤604，所述网络设备向所述终端设备发送包括上行数据触发信息的第一控制信息，
步骤605，所述终端设备在所述数据调度控制信息指示的可用时频资源和所述第 一指示信息指示的一个或多个频域带宽资源重合的带宽中的可用时频资源上，向所述网络设备发送上行数据。
值得注意的是，以上附图6仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图6的记载。
在一个实施方式中，所述第一指示信息和所述数据调度控制信息可以在同一信道占用时间内发送。
图7是本发明实施例的第一指示信息和数据调度控制信息的一示意图。如图7所示，终端设备在接收到数据调度控制信息后，还需等待第一指示信息，接收到所述第一指示信息后，根据这两个信息的指示内容发送上行数据。
例如，终端设备可以分享网络设备的信道占用时间(COT：Channel Occupancy Time)来发送数据，由网络设备通知终端设备可分享的带宽大小。例如，网络设备在发送数据调度控制信息前检测信道空闲状态，根据检测结果得到空闲带宽大小，在空闲的频域带宽资源上发送数据调度控制信息，但由于数据调度控制信息已经打包编码，并且需要立即发送，所以带宽信息无法承载在该信息中通知终端设备可以共享的带宽大小，因此，终端设备需要等待第一指示信息，确定可以传输数据的带宽大小后传输上行数据。
在另一个实施方式中，所述第一指示信息和所述数据调度控制信息可以在不同的信道占用时间内发送。例如，可以应用于网络设备跨COT调度终端设备的情况。
图8是本发明实施例的第一指示信息和数据调度控制信息的另一示意图。如图8所示，例如，在上一次COT中网络设备向终端设备发送数据调度控制信息，在网络设备获得了新的COT后，可以告知终端设备能够与其分享的带宽，这样在新的COT中可以快速地进行上行调度，而不会因为上行调度时序制约而不能调度新的COT的前面部分符号来传输上行数据。
值得注意的是，网络设备的非授权频段的信道占用时间(COT)仅是时序关系的参照，本发明实施例不对数据调度控制信息及带宽指示发送在非授权频段上进行限制，也可以在授权频段上发送。
在一个实施方式中，所述第一指示信息在所述数据调度控制信息之前发送。例如， 当收到数据调度控制信息后，终端设备可以判断是否存在有效的第一指示信息，若存在有效的第一指示信息，则在数据调度控制信息指示的可用时频资源与第一指示信息指示的一个或多个频域带宽资源所重合的带宽中的可用资源上传输上行数据。
在一个实施方式中，第一指示信息与数据调度控制信息的发送时刻没有特定的时序关系，即，第一指示信息既可以在数据调度控制信息之前发送，也可以在数据调度控制信息之后发送。
图9是本发明实施例的第一指示信息和数据调度控制信息的另一示意图。如图9所示，例如，终端设备在接收到一个数据调度控制信息之后，可以判断是否存在有效的第一指示信息。若存在有效的第一指示信息(第一指示信息1有效)，且发送上行数据的时刻仍处于该第一指示信息的有效时长内，则根据数据调度控制信息及第一指示信息的指示内容发送上行数据。
图10是本发明实施例的第一指示信息和数据调度控制信息的另一示意图。如图10所示，例如，终端设备在接收到一个数据调度控制信息之后，若不存在有效的第一指示信息(没有收到过第一指示信息或第一指示信息1失效)，则终端设备等待接收承载了第一指示信息的控制信息；终端设备在接收到该控制信息(第一指示信息2)后，可以根据数据调度控制信息及该第一指示信息的指示内容发送上行数据。
有效的第一指示信息可以是上一次接收到的第一指示信息，该指示可能用于通知终端设备可以用于数据传输的带宽大小的信息；也可以是网络设备上一次指示终端设备下行成功传输的带宽大小的信息。网络设备通知传输带宽的有效时长的方式，可以是在通知第一指示信息的控制信息中由一个单独的指示域通知；也可以在该控制信息中通过一个指示域联合指示第一指示信息的内容和有效时长；还可以通过网络设备的信道占用时间相关信息隐式地指示有效时长；还可以有一个默认的有效时长，超出时长则失效。
以上对第一指示信息的发送进行了示意性说明，以下对上行数据进行说明。
在一个实施方式中，所述网络设备在所述第一指示信息所指示的一个或多个频域带宽资源和数据调度控制信息指示的可用时频资源所重合的带宽中的可用时频资源上接收所述上行数据。
图11是本发明实施例的发送上行数据的部分带宽的一示意图，其中数据调度控制信息可以指示调度带宽资源中可用于发送上行数据的可用时频资源。如图11所示， 终端设备接收到第一指示信息后，在可用时频资源与第一指示信息所指示的一个或多个频域带宽资源所重合的带宽中的可用时频资源上发送上行数据。
例如，第一指示信息1所指示的频域带宽资源少于调度带宽资源，重合的部分可以为第一指示信息1所指示的频域带宽资源，如图11中的重合带宽1所示。再例如，第一指示信息2所指示的频域带宽资源多于调度带宽资源，重合的部分可以为调度带宽包含的频域带宽资源，如图11中的重合带宽2所示。
数据调度控制信息还可以指示调度带宽中调度的频域带宽资源的个数，或调度的频域带宽资源的大小和个数。终端设备在接收到第一指示信息后，可以在第一指示信息所指示的频域带宽资源上发送，若调度的频域带宽资源个数小于第一指示信息指示的传输带宽中包含的频域带宽资源的个数时可以按照一定规则在默认带宽上发送。
可以在第一指示信息指示的传输带宽的前调度的频域带宽资源个数个频域带宽资源上发送上行数据。例如，数据调度控制信息指示调度了2个频域带宽资源，并不指示起始、终止或具体在带宽中的位置，终端设备根据两个频域带宽资源的大小，可以确定传输块尺寸(TBS：Transport Block Size)，进行编码、速率匹配等，接收到第一指示信息后确定传输带宽大小为4个频域带宽资源及其频域位置，那么调度的2个频域带宽资源的数据将在传输带宽中的前两个频域带宽资源上发送；或者规定第一指示信息所指示频域带宽资源的个数不大于调度的频域带宽资源的个数，若调度的频域带宽资源个数大于指示的传输带宽中包含的频域带宽资源的个数，则仅在所指示的传输带宽上发送上行数据。
在本实施例中，所述调度带宽资源可以为默认大小；或者所述调度带宽可以由所述网络设备通过以下至少一种方式通知所述终端设备：通过所述数据调度控制信息指示所述调度带宽资源；通过高层信令配置所述调度带宽资源；通过系统信息配置所述调度带宽资源。
在一个实施方式中，所述第一控制信息为用户专用控制信息或者公共控制信息；所述第一控制信息还包括用于指示上下行结构的第二指示信息。其中，所述第一控制信息还可以包括指示所述第一指示信息的有效时长的信息，或者，所述第二指示信息还用于指示所述第一指示信息的有效时长。
例如，上下行结构的第二指示信息可以隐式地指示：在该第一控制信息指示的上下行持续时间内该第一指示信息有效；或者，在第二控制信息中的一个域指示有效时 长，指示内容可以是候选有效时长中某一个的索引值。如果是公共控制信息，可以是NR中SFI-RNTI加扰的slot format指示，也可以是新的扰码序列加扰的公共控制信息。
在一个实施方式中，所述有效时长和/或所述上下行结构指示信息的单位可以为符号、时隙、子帧、毫秒中的至少一个；但本发明不限于此。
在一个实施方式中，如果所述上行数据的发送时刻在一个第一指示信息的有效时长内，则所述网络设备在所述发送时刻接收所述上行数据；如果所述上行数据的发送时刻不在一个第一指示信息的所述有效时长内，则所述网络设备在发送了下一个第一指示信息后接收所述上行数据。
例如，所述数据调度控制信息可以包含指示所述发送时刻的相关信息(例如时域资源分配指示信息，所述发送时刻与所述数据调度控制信息的相对符号个数间隔、时隙间隔的指示信息，所述发送时刻的绝对时间信息，或者所述发送时刻相对于基准时间的相对时间信息，等等)；但不限于此。
在一个实施方式中，所述第一指示信息在以下至少之一的资源上发送：所述一个或多个频域带宽资源的频域资源集合；所述一个或多个频域带宽资源中的一个频域带宽资源；所述一个或多个频域带宽资源中的每一个频域资源；所述网络设备预先分配的授权频段的资源。
在一个实施方式中，第一指示信息可以是显式地指示用于发送上行数据的频域带宽资源的信息，终端设备在读取指示信息内容后获得发送上行数据的频域带宽资源。
例如，第一指示信息是一个位图(bitmap)，bitmap的比特个数与调度带宽资源中包含的频域带宽资源个数相等，且一个比特对应地指示一个频域带宽资源。比特置‘1’表示与该比特对应的频域带宽资源可以发送上行数据，置‘0’表示与该比特对应的频域带宽资源不可用于发送上行数据；或者，置‘0’表示与该比特对应的频域带宽资源可以发送上行数据，置‘1’表示与该比特对应的频域带宽资源不可用于发送上行数据。但本发明不限于此，例如也可以由两个或以上比特指示一个频域带宽资源。
再例如，第一指示信息是指示资源指示值(RIV：Resource Indication Value)，即通过三角形二叉树的编码方式，由资源指示值确定调度带宽资源中发送上行数据的带宽资源的起始频域带宽资源及频域带宽资源个数。
以上各个实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实 施方式，也可以将以上各个实施方式中的一种或多种结合起来。
由上述实施例可知，网络设备向终端设备发送用于指示一个或多个频域带宽资源的第一指示信息。由此，网络设备和终端设备能够对实际使用的频域带宽资源达成一致，能够提高频谱资源利用效率、减少传输时延，并保证调度的灵活性。

在一个实施方式中，所述第一控制信息为用户专用控制信息或者公共控制信息；所述上行数据触发信息还包括指示上下行结构的第二指示信息。

在一个实施方式中，如果所述上行数据的发送时刻在一个第一指示信息的有效时长内，则所述终端设备在所述发送时刻发送所述上行数据；如果所述上行数据的发送时刻不在一个第一指示信息的所述有效时长内，则所述终端设备在接收到下一个第一指示信息后发送所述上行数据。

当终端设备需要检测调度带宽资源内的多个频域带宽资源的空闲状态后再进行数据传输时，终端设备在检测为空闲的频域带宽资源上传输上行数据，可以在传输完成后发送第一指示信息，通知网络设备传输了数据的频域带宽资源，即终端设备检测为空闲且被该终端设备占用的信道带宽资源。
在一个实施方式中，第一指示信息可以在网络设备预先分配的资源上发送。
例如，网络设备在调度带宽资源中的每一个频域带宽单元上分配第一指示信息的资源，第一指示信息可以在检测为空闲状态的每一个频域带宽资源的预分配资源上发送重复发送，或者，在检测为空闲状态的频域带宽资源的预分配资源组成的资源集合上发送第一指示信息，即在传输了上行数据的频域带宽资源内预先分配的资源上发送。
在一个实施方式中，第一指示信息可以在按照一定规则得到的某一个检测为空闲状态的频域带宽资源上发送。
例如，在检测为空闲状态的带宽单元中的第一个或最后一个频域带宽资源上发送 第一指示信息。如果调度带宽资源中包含4个带宽单元，终端设备检测到第1个带宽单元为忙碌状态，第2、3、4个带宽单元为空闲状态，则第一指示信息在第2个带宽单元上发送，网络设备在该带宽单元上检测到第一指示信息后确定传输带宽的起始位置为第2个带宽单元，根据第一指示信息的内容进一步确定其正确性及传输带宽的宽度。
在一个实施方式中，第一指示信息可以是指示信息，网络设备在读取指示信息内容后获得传输了上行数据的频域带宽资源。
例如，第一指示信息是一个bitmap，bitmap的比特个数与调度带宽资源中包含的频域带宽资源个数相等，且一个比特对应地指示一个频域带宽资源。比特置‘1’表示与该比特对应的频域带宽资源传输了上行数据，置‘0’表示与该比特对应的频域带宽资源没有传输上行数据；或者，置‘0’表示与该比特对应的频域带宽资源传输了上行数据，置‘1’表示与该比特对应的频域带宽资源没有传输上行数据。但本发明不限于此，例如也可以由两个或以上比特指示一个频域带宽资源。
再例如，第一指示信息是指示资源指示值(RIV：Resource Indication Value)，即通过三角形二叉树的编码方式，由资源指示值确定调度带宽资源中发送上行数据的起始频域带宽资源及频域带宽资源个数。
在一个实施方式中，第一指示信息还可以是一段默认序列符号。
例如，终端设备在传输了数据的带宽单元上发送该默认序列符号，网络设备在每一个带宽单元上检测该默认序列符号，并认为检测到默认序列符号的带宽单元传输了上行数据。所述默认序列可以是SRS(Sounding Reference Signal)，也可以是其他序列符号。网络设备可以通过序列的相关性检测默认序列符号，但不限于此。
在一个实施方式中，所述预先分配的资源可以是与该终端设备相连接的授权频段上的资源。终端设备在数据发送完成后在授权频段的相应资源上发送第一指示信息。在授权频段的上行资源反馈第一指示信息可以由网络设备通过高层信令配置给终端设备。
例如，网络设备向终端设备的频域带宽资源的配置信息中，包含反馈带宽资源指示配置信息或反馈载波指示配置信息，用于配置其反馈第一指示信息的授权频段或授权频段载波。该配置信息可以为可选配置，当该带宽资源不包含多个带宽单元时，或该带宽不需要反馈第一指示信息时，可以不配置该信息。
在一个实施方式中，所述预先分配的资源可以是PUSCH或PUCCH资源的一部分，或者是其他资源。
在一个实施方式中，所述第一指示信息还可以用于指示网络设备可以共享发送该第一指示信息的终端设备的信道占用时间(COT：Channel Occupancy Time)；也就是说网络设备在接收到该指示后，确定可以共享的频域带宽资源，在检测和/或不检测信道空闲的情况下，在该终端设备的信道占用时间内在共享的带宽单元上发送下行数据。
在一个实施方式中，网络设备可以根据数据调度控制信息中的信道接入优先级指示域确定终端设备的最大信道占用时间，并判断是否能够共享终端设备的信道占用时间。也可以通过终端设备发送的承载了第一指示信息的信息中的一个域进行指示网络设备可共享的信道占用时长，该域的指示粒度可以是可占用的符号个数、符号组组数或时隙个数。还可以和第一指示信息联合指示，其指示的是第一指示信息的指示内容与信道占用时间的多种组合的索引值。
在一个实施方式中，终端设备还可以仅检测调度带宽资源内一个频域带宽资源的空闲状态，判断是否在整个调度带宽资源传输上行数据。若检测结果为空闲，则终端设备在整个调度带宽资源上传输上行数据；若检测结果为忙碌，则不传输上行数据。在这种情况下由于终端设备不会在部分调度带宽资源上传输上行数据，因此，当终端设备仅检测一个频域带宽资源的空闲状态时，不反馈第一指示信息。
所述一个频域带宽资源，可以是调度带宽资源本身；也可以是调度带宽资源中多个频域带宽资源中的一个，网络设备指示终端设备检测其中一个频域带宽资源，则整个调度带宽中的所有带宽单元的数据是否发送由在该频域带宽资源的检测结果决定。
例如，需要检测的频域带宽资源可以为一默认带宽单元，网络设备的调度带宽中的第一个或最后一个频域带宽资源，或处于中间位置的某一带宽，例如第
Figure PCTCN2018098595-appb-000001
或
Figure PCTCN2018098595-appb-000002
个带宽单元。
例如，需要检测的频域带宽资源可以由数据调度控制信息中的一个域告知终端设备：本次调度需要检测空闲状态的频域带宽资源，或与其他信息联合指示。
再例如，需要检测的频域带宽资源还可以由网络设备通过信令指示给终端设备，指示该频域带宽资源的信令可以是高层配置信令。
在一个实施方式中，可以在该频域带宽资源的配置信息中包含检测空闲状态配置 信息，指示终端设备是否在该频域带宽资源检测信道空闲状态；也可以在带宽配置信息中包含检测空闲状态频域带宽资源指示配置信息，指示在该带宽中的一个或多个频域带宽资源的索引，表示需要检测信道空闲状态的频域带宽资源。
以上各个实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实施方式，也可以将以上各个实施方式中的一种或多种结合起来。
由上述实施例可知，终端设备向网络设备发送用于指示一个或多个频域带宽资源的第一指示信息。由此，网络设备和终端设备能够对实际使用的频域带宽资源达成一致，能够提高频谱资源利用效率、减少传输时延，并保证调度的灵活性。

在本实施例中，所述终端设备根据所述网络设备的指示检测调度带宽中的频域带宽资源；并且所述终端设备根据一个或多个带宽的检测结果确定所述一个或多个频域带宽资源。
在一个实施方式中，所述调度带宽可以为非授权频段频域资源。
在一个实施方式中，所述调度带宽资源为一个默认大小；或者，所述调度带宽由所述网络设备通过以下至少一种方式通知所述终端设备：通过所述数据调度控制信息指示所述调度带宽资源；通过高层信令配置所述调度带宽资源；通过系统信息配置所 述调度带宽资源。

在一个实施方式中，所述第一指示信息在所述上行数据之后被所述终端设备发送。
在一个实施方式中，所述终端设备在发送了所述上行数据的频域资源上发送所述第一指示信息，或者，在发送了所述上行数据的一个或多个频域带宽资源中的一个频域带宽资源上发送所述第一指示信息，或者，在发送了所述上行数据的每一个频域带宽资源上发送所述第一指示信息，或者，在所述网络设备预先分配的资源上发送所述第一指示信息。
以上各个实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式的基础上进行适当的变型。例如，可以单独使用上述各个实施方式，也可以将以上各个实施方式中的一种或多种结合起来。
由上述实施例可知，终端设备向网络设备发送用于指示一个或多个频域带宽资源的第一指示信息。由此，网络设备和终端设备能够对实际使用的频域带宽资源达成一致，能够提高频谱资源利用效率、减少传输时延，并保证调度的灵活性。
实施例5
本实施例在实施例1-4的基础上进行进一步说明。
在本实施例中，系统可以单独采用上述触发调度方式和非触发调度方式中的一种，也可以同时支持以上两种调度。例如，可以由高层配置信令通知终端设备采用其中的一种调度方式。
在一个实施方式中，所述网络设备向所述终端设备发送调度方式信息；其中所述调度方式信息指示所述终端设备使用上行数据触发信息发送所述上行数据(触发调度方式)，或者指示所述终端设备不使用上行数据触发信息发送所述上行数据(非触发调度方式)。
例如，由数据调度控制信息中的一个域通知本次调度为触发调度还是非触发调度。可以由1比特的调度方式在指示域中进行指示：‘0’表示为非触发调度，终端设备在收到该指示域后根据调度指示来发送上行数据，在发送数据后根据需要检测的频域带宽 资源的个数判断是否向网络设备发送第一指示信息。‘1’表示为触发调度，终端设备在收到该指示域后，再根据有效的第一指示信息发送上行数据。调度方式指示还可以由‘1’表示非触发调度，‘0’表示触发调度。
在另一个实施方式中，所述网络设备向所述终端设备发送非授权频段的信道接入方式指示信息；其中所述非授权频段的信道接入方式指示信息指示所述终端设备确定使用上行数据触发信息发送所述上行数据(触发调度方式)，或者指示所述终端设备确定不使用上行数据触发信息发送所述上行数据(非触发调度方式)。
例如，由信道接入状态隐式地指示调度方式。当所指示信道接入类型为包含竞争窗的完整LBT时，类似于LTE信道接入类型1，则隐式指示本次调度为非触发调度；当所指示信道接入类型为类似于LTE信道接入类型2，仅检测一个固定时间的信道空闲状态，若为空闲便立即发送数据，或发送时间间隔小于默认时长则无需检测信道空闲状态的情况下，则隐式指示本次调度为触发调度。
