Description

数据传输方法及装置
本申请要求于2022年9月29日提交中国国家知识产权局、申请号为202211200149.5、申请名称为“数据传输方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种数据传输方法及装置。
背景技术
随着通信技术的不断发展，数据传输时延不断降低，传输容量越来越大，网络设备与终端设备之间可能会传输一些实时性强、数据量大的多媒体业务，例如，视频业务、云游戏(Cloud Gaming)、扩展现实(eXtended Reality，XR)业务等。
这些业务中的数据具有周期性传输的特性。以网络设备与终端设备之间进行下行传输为例，在理想情况下，服务器周期性地将数据发送给网络设备，数据可以周期性地到达网络设备即数据在预期时间到达网络设备，那么网络设备可周期性地将数据发送给终端设备。然而，由于服务器编码处理、固网/核心网传输等因素，在每个周期内，数据实际到达网络设备的时间相比于预期时间可能存在抖动，也就是说相比于预期时间，实际上数据可能提前到达网络设备，也可能延后到达网络设备。网络设备与终端设备之间进行上行传输的情况与下行传输的情况类似，上行传输中终端设备向网络设备发送的数据也可能存在抖动。
在每个周期内，如果半持续调度(semi-persistent scheduling，SPS)或配置授权(configured grant，CG)的资源被配置在预期时间之前，在数据早于预期时间到达时传输数据的时延较小，但在数据晚于预期时间到达会错过当前周期内的资源，需在下一周期内的资源上传输数据，导致时延较大。如果资源被配置在预期时间之后，在数据晚于预期时间到达时传输数据的时延较小，但在数据早于预期时间到达时，需等到配置了资源的时间才能传输数据，导致时延较大。那么如何减少传输数据的时延是一个亟待解决的问题。
发明内容
本申请实施例提供一种数据传输方法及装置，能够减少传输数据的时延。
第一方面，本申请提供一种数据传输方法，该方法可应用于终端设备，也可以应用于终端设备中的芯片，还可以应用于能实现全部或部分终端设备功能的逻辑模块或软件。下面终端设备为例进行描述。该方法包括：终端设备接收来自网络设备的第一信息；终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗，并在M个时间窗中的Y个时间窗与网络设备进行数据传输；N为大于1的整数，M是小于N的正整数，Y是小于M的正整数。
可见，在第一时段中用于数据传输的时间窗可以是多个，第一时段中的数据提前于预期时间到达时，终端设备可在靠前的用于数据传输的时间窗接收或发送数据；数据延后于预期时间到达时，终端设备可在靠后的用于数据传输的时间窗接收或发送数据，有利于减少传输数据(发送/接收数据)的时延。
并且，该方式应用于数据具有周期性传输这一特性的XR业务或视频业务时，针对每个周期可配置N个时间窗以及N个时间窗中用于数据传输的M个时间窗，每个周期内用于数据传输的M个时间窗可以是由一个SPS/CG配置的，M的取值可以不受配置的SPS/CG个数的限制，从而在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延。另外，用于数据传输的M个时间窗由一个SPS/CG进行配置这一方式还可以减少为激活用于数据传输的时间窗而交互的信令开销。
在一种可选的实施方式中，该方法还包括：终端设备在M个时间窗中除Y个时间窗之外的M-Y个时间窗不与网络设备进行数据传输。也就是说终端设备可以释放(/去激活)M-Y个时间窗，从而该M-Y个时间窗可用于其他使用，例如，该M-Y个时间窗可用于其他用户数据传输，有利于提升整体通信系统的吞吐量。
在一种可选的实施方式中，数据传输是半持续调度(semi-persistent scheduling，SPS)传输。终端设备在M-Y个时间窗不与网络设备进行数据传输，包括：终端设备根据第二信息，确定在M-Y个时间窗不与网络设备进行数据传输；第二信息用于指示第一时段内的数据传输的完成。可见，在Y个时间窗完成了第 一时段内的数据传输的情况下，终端设备可以释放(/去激活)剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量。并且，在SPS传输中，终端设备通过第二信息获知第一时段内的数据传输完成，即可释放剩余的M-Y个时间窗，无需网络设备额外发送用于指示终端设备释放M-Y个时间窗的信令，能够节省信令开销。
在一种可选的实施方式中，第二信息是在Y个时间窗中的最后一个时间窗接收到的。例如，该第二信息可以携带于终端设备在Y个时间窗中的最后一个时间窗中接收到的数据中，这样，终端设备可基于接收的数据获知第一时段内的数据传输是否完成，进而可在第一时段内的数据传输完成时释放M个时间窗中剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量以及节省信令开销。
在一种可选的实施方式中，数据传输是配置授权(configured grant，CG)传输。该方法还包括：终端设备在Y个时间窗中的最后一个时间窗向网络设备发送第三信息，第三信息用于指示第一时段内的数据传输的完成。在CG传输中，终端设备可以通过第三信息告知网络设备第一时段内的数据传输完成，进而有利于网络设备在获知了第一时段内的数据传输完成时释放M个时间窗中剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量。并且，终端设备也无需额外发送用于指示网络设备释放M-Y个时间窗的信令，节省了信令开销。
在一种可选的实施方式中，第一信息用于指示比特位图；比特位图中每个比特位与N个时间窗中至少一个时间窗相对应，每个比特位的值用于表征该比特位对应的时间窗是否用于数据传输。那么，终端设备可以基于第一信息所指示比特位图确定N个时间窗中用于数据传输的M个时间窗，进而可在该M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，第一信息用于配置M的取值；M个时间窗在N个时间窗中的位置是预定义的。可以预定义M个时间窗在N个时间窗中的位置分布方式，那么终端设备在获取了M的取值之后，可基于预定义的位置分布方式从N个时间窗中确定用于数据传输的M个时间窗，进而可在该M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，该方法还包括：终端设备接收来自网络设备的第四信息，第四信息用于配置第一时段的时长。该实施方式有利于终端设备基于获知的第一时段的时长来确定第一时段的N个时间窗以及用于数据传输的M个时间窗，从而可在M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，M个时间窗包括N个时间窗中的最后一个时间窗。该方式能够确保下行时来自网络设备的数据能够在N个时间窗的范围内被终端设备接收，上行时数据能够在N个时间窗的范围内由终端设备发送给网络设备。在下行中，即使网络设备在N个时间窗的范围中较晚时间接收到来自服务器的数据，也可以在N个时间窗中的最后一个时间窗将数据发送给终端设备，终端设备能够在N个时间窗中的最后一个时间窗接收该数据。在上行中，即使终端设备在N个时间窗的范围中较晚时间获取到数据，也可以在N个时间窗中的最后一个时间窗将数据发送给网络设备。可见，该方式能够减少由于终端设备在N个时间窗的范围内无法发送或接收数据而对数据的传输性造成的影响，如时延较大。
该实施方式应用于XR业务或视频业务中时，第一时段的N个时间窗可以是将数据的抖动范围划分的N个时间窗，该方式可确保当前周期内的数据即使在抖动范围的最晚时间到达时终端设备也可以在当前周期内发送或接收该数据，而不用等待至下一周期内的用于数据传输的时间窗才能发送或接收当前周期内的数据，减少时延。
第二方面，本申请提供一种数据传输方法，该方法可应用于网络设备，也可以应用于终端设备中的芯片，还可以应用于能实现全部或部分网络设备功能的逻辑模块或软件。下面终端设备为例进行描述，该方法包括：网络设备向终端设备发送第一信息；第一信息用于配置在第一时段的N个时间窗中用于数据传输的M个时间窗。网络设备在M个时间窗中的Y个时间窗与终端设备进行数据传输；N为大于1的整数，M是小于N的正整数，Y是小于M的正整数。
可见，在第一时段中用于数据传输的时间窗可以是多个，第一时段中的数据提前于预期时间到达时，网络设备可在靠前的用于数据传输的时间窗发送或接收数据；数据延后于预期时间到达时，网络设备可在靠后的用于数据传输的时间窗发送或接收数据，有利于减少传输数据(发送/接收数据)的时延。
并且，该方式应用于数据具有周期性传输这一特性的XR业务或视频业务时，针对每个周期可配置N个时间窗以及N个时间窗中用于数据传输的M个时间窗，每个周期内用于数据传输的M个时间窗可以是由一个SPS/CG配置的，M的取值可以不受配置的SPS/CG个数的限制，从而在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延。另外，用于数据传 输的M个时间窗由一个SPS/CG进行配置这一方式还可以减少为激活用于数据传输的时间窗而交互的信令开销。
在一种可选的实施方式中，该方法还包括：网络设备在M个时间窗中除Y个时间窗之外的M-Y个时间窗不与终端设备进行数据传输。也就是说网络设备可以释放(/去激活)M-Y个时间窗，从而该M-Y个时间窗可用于其他使用，例如，该M-Y个时间窗可用于其他用户数据传输，有利于提升整体通信系统的吞吐量。
在一种可选的实施方式中，数据传输是半持续调度SPS传输。该方法还包括：网络设备在Y个时间窗中的最后一个时间窗向终端设备发送第二信息，第二信息用于指示第一时段内的数据传输的完成。在SPS传输中，网络设备可以通过第二信息告知终端设备第一时段内的数据传输完成，进而有利于终端设备在获知了第一时段内的数据传输完成时释放M个时间窗中剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量。并且，网络设备也无需额外发送用于指示终端设备释放M-Y个时间窗的信令，节省了信令开销。
在一种可选的实施方式中，数据传输是配置授权CG传输；网络设备在M-Y个时间窗不与终端设备进行数据传输，包括：网络设备根据第三信息，确定在M-Y个时间窗不与终端设备进行数据传输；第三信息用于指示第一时段内的数据传输的完成。可见，在Y个时间窗完成了第一时段内的数据传输的情况下，网络设备可以释放剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量。并且，在CG传输中，网络设备通过第三信息获知了第一时段内的数据传输完成，即可释放剩余的M-Y个时间窗，无需终端设备额外发送用于指示网络设备释放M-Y个时间窗的信令，能够节省信令开销。
在一种可选的实施方式中，第三信息是在Y个时间窗中的最后一个时间窗接收到的。例如，该第二信息可以携带于网络设备在Y个时间窗中的最后一个时间窗中接收到的数据中，这样，网络设备可基于接收的数据获知第一时段内的数据传输是否完成，进而可在第一时段内的数据传输完成时释放M个时间窗中剩余的M-Y个时间窗，有利于提升整体通信系统的吞吐量以及节省信令开销。
在一种可选的实施方式中，第一信息用于指示比特位图；比特位图中每个比特位与N个时间窗中至少一个时间窗相对应，每个比特位的值用于表征该比特位对应的时间窗是否用于数据传输。该方式有利于终端设备基于第一信息所指示比特位图确定N个时间窗中用于数据传输的M个时间窗，进而可在该M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，第一信息用于配置M的取值；M个时间窗在N个时间窗中的位置是预定义的。可见，可以预定义M个时间窗在N个时间窗中的位置分布方式，有利于终端设备在获取了M的取值之后，可基于预定义的位置分布方式从N个时间窗中确定用于数据传输的M个时间窗，进而可在该M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，该方法还包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。该实施方式有利于终端设备基于第一时段的时长来确定第一时段的N个时间窗以及用于数据传输的M个时间窗，从而可在M个时间窗中的Y个时间窗进行数据传输，有利于减少传输数据的时延，以及减少信令开销。
在一种可选的实施方式中，M个时间窗包括N个时间窗中的最后一个时间窗。该方式能够确保下行时数据能够在N个时间窗的范围内由网络设备发送给终端设备，上行时来自终端设备的数据能够在N个时间窗的范围内被网络设备接收。在下行中，即使网络设备在N个时间窗的范围中较晚时间接收到来自服务器的数据，也可以在N个时间窗中的最后一个时间窗将数据发送给终端设备。在上行中，即使终端设备在N个时间窗的范围中较晚时间获取到数据，也可以在N个时间窗中的最后一个时间窗将数据发送给网络设备，网络设备能够在N个时间窗中的最后一个时间窗接收该数据。可见，该方式能够减少由于网络设备在N个时间窗的范围内无法发送或接收数据而对数据的传输性造成的影响，如时延较大。
该实施方式应用于XR业务或视频业务中时，第一时段的N个时间窗可以是将数据的抖动范围划分的N个时间窗，该方式可确保当前周期内的数据即使在抖动范围的最晚时间到达时网络设备也可以在当前周期内发送或接收该数据，而不用等待至下一周期内的用于数据传输的时间窗才能发送或接收当前周期内的数据，减少时延。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
首先，为了更好的理解本申请实施例公开的数据传输方法，对本申请实施例适用的通信系统进行描述。
本申请实施例的技术方案可应用于各种通信系统中。例如，全球移动通信系统、长期演进(long term evolution，LTE)系统、通用移动通信系统、第四代移动通信技术(4th generation，4G)系统、下一代无线接入网(next-generation radio access network，NG-RAN)、新空口技术(new radio，NR)系统、第五代移动通信技术(5th generation mobile networks，5G)系统，以及随着通信技术的不断发展，本申请实施例的技术方案还可用于后续演进的通信系统，如第六代移动通信技术(6th generation mobile networks，6G)系统、第七代移动通信技术(7th generation mobile networks，7G)系统等等。

其次，对本申请实施例涉及的相关概念进行简单的介绍。
1.扩展现实(extended reality，XR)
XR是一种能够将实境和虚拟环境相结合且可供人机交互的技术，XR包括AR和VR。
AR是指透过摄影机影像的位置、角度并结合图像分析技术，让屏幕上的虚拟世界能够与现实世界场景进行结合与交互的技术。
VR是一种可利用电脑模拟产生一个三维空间的虚拟世界，并且能够为用户提供关于视觉等感官模拟的技术，其可以让用户感觉仿佛身临其境，能够即时且没有限制地观察三维空间内的事物。VR具有多视角、交互性强等特性，其可应用于教育、娱乐、军事、医疗、环保、交通运输、公共卫生等各种与人们生产、生活息息相关的领域中。
2.抖动(jitter)
抖动是指数据实际上的到达时间相比于理想的预期时间提前或延后。在抖动对应的数值小于0即jitter<0时，说明数据的到达时间提前于预期时间；在jitter＝0时，说明数据的到达时间刚好在预期时间；在jitter>0时，说明数据的到达时间延后于预期时间。其中，数据可以是XR业务或视频业务中的视频帧，XR业务或视频业务中的视频帧具有周期性传输的特性，视频帧的传输周期为帧率的倒数。
在针对视频帧的下行传输的过程中，服务器将视频帧发送给网络设备，网络设备再将接收到的视频帧 发送给终端设备。在理想情况下，服务器是周期性地将视频帧发送给网络设备的，每个周期内的视频帧在该周期内的预期时间到达网络设备，进而每个周期内的视频帧会在该周期内的预期时间到达终端设备。例如，结合图2，视频帧的帧率为60帧每秒(frame per second，FPS)，即视频帧的周期为秒(second，s)≈16.67毫秒(millisecond，ms)，那么理想情况下视频帧以16.67ms为周期到达网络设备，也就是说，理想情况下每间隔16.67ms有一个视频帧到达网络设备，图2中采用虚线所标记的时间为预期时间。
在实际情况中，由于服务器编码处理、固网/核心网传输等因素，在每个周期内，实际上视频帧可能刚好在预期时间到达网络设备，也可能提前于预期时间到达，还可能延后于预期时间到达。例如，结合图2，不同周期内视频帧实际的到达时间与预期时间之间的差值可能不等，也就是说视频帧可能不是严格地按照16.67ms的周期到达网络设备的，如图2中，第2个视频帧的到达时间相比于预期时间延后了5ms即第2个时频帧的jitter＝5ms，第4个视频帧的到达时间相比于对应的预期时间提前了3ms即第4个时频帧的jitter＝-3ms。
另外，上行传输中数据的抖动与下行传输类似，在上行传输中，终端设备要对数据进行编码处理，在编码处理完成后才能将该数据发送给网络设备，因此数据存在编码处理时延，而终端设备针对不同数据帧的编码处理时延可能不同，使得终端设备向网络设备发送数据的时间可能存在抖动。
抖动范围(jitter range)是指相比于预期时间，数据可能到达的时间范围。例如，数据最早在提前于预期时间4ms的时间到达，最晚在延后于预期时间4ms的时间到达，那么抖动范围为[-4ms，4ms]。另外，抖动范围在数学统计上服从特定的概率分布，该概率分布可以为高斯分布、瑞利分布、莱斯分布等统计分布。例如，抖动范围服从均值为0、方差为2ms的截断高斯分布时，抖动范围为[-4ms，4ms]。
3.半持续调度(semi-persistent scheduling，SPS)
SPS是指网络设备通过下行控制信道(physical downlink control channel，PDCCH)分配指定一次用于下行传输的时频资源，网络设备和终端设备可以周期性地重复使用该时频资源进行下行传输，可见，SPS具有“一次分配，多次使用”的特性，可以有效地降低PDCCH的开销。SPS可应用于数据具有周期性传输这一特性的业务的下行传输中，例如SPS可应用于XR业务或视频业务的下行传输中。另外，基于SPS配置的用于进行下行传输的时频资源还可以称为SPS资源，采用SPS资源进行的下行传输还可以称为SPS传输。
具体地，结合图3，网络设备可在无线资源控制(radio resource control，RRC)信令中携带SPS的相关参数以配置SPS资源(属于下行资源)的周期性。网络设备还可向终端设备发送PDCCH，该PDCCH中携带了用于激活SPS资源的下行控制信息(downlink control information，DCI)，该DCI指示了激活的SPS资源中的频域资源分配(frequency domain allocation assignment，FDRA)，以及调制和编码方案(modulation and coding scheme，MCS)。终端设备可基于接收到的用于激活SPS资源的DCI，确定周期性生效的SPS资源所在的时隙。那么，终端设备可在激活的SPS资源上周期性地接收来自网络设备的物理下行链路共享信道(physical downlink shared channel，PDSCH)。另外，如果需要释放SPS资源(还可称为去激活SPS资源)，网络设备可再次发送PDCCH，该PDCCH中携带了用于释放SPS资源的DCI，该DCI指示了需要释放的SPS资源。
其中，RRC信令中携带的SPS的相关参数可由RRC信令中SPS配置(即SPS-Config)中的一个或多个字段来指示。RRC信令中携带的SPS的相关参数可包括：配置调度无线网络临时标识(configured scheduling radio network temporary identifier，CS-RNTI)、SPS周期、混合自动重传请求进程(hybrid automatic repeat request process，HARQ Process)的数量以及HARQ Process索引值(HARQ Process identity document，HARQ Process ID)的起始偏移等；如果要配置多个SPS，SPS的相关参数还包括每个SPS对应的索引值。
在NR中，SPS周期为NR支持的时隙长度(即一个时隙的时长)的整数倍，即SPS周期等于k×时隙长度，k为正整数。例如，子载波间隔为15千赫兹(kilohertz，kHz)时，时隙长度为1ms，k为小于或等于640的正整数。子载波间隔为30KHz时，时隙长度为0.5ms，k为小于或等于1280的正整数。子载波间隔为60kHz且采用常规循环前缀(normal cyclic prefix，NCP)，或者，子载波间隔为60kHz且采用扩展循环前缀(extend cyclic prefix，ECP)时，时隙长度为0.25ms，k为小于或等于2560的正整数。子载波间隔为120kHz时，时隙长度为0.125ms，k为小于或等于5120的正整数。
用于激活SPS资源的DCI中的字段需满足下述条件：(1)循环冗余码校验(cyclic redundancy check，CRC)采用RRC信令中提供的CS-RNTI加扰。(2)新传数据指示(new data indicator，NDI)全置‘0’。(3)HARQ进程数(即HARQ Process Number)全置‘0’。另外，当配置了多个SPS时，HARQ Process Number 将不是全置‘0’，而是指示激活的SPS资源对应的HARQ Process Number。(4)冗余版本(redundancy version，RV)全置‘0’。
终端设备在接收了用于激活SPS资源的DCI之后，终端设备可基于下述公式来确定周期性生效的SPS资源所在的时隙(slot)：(numberOfSlotsPerFrame×SFN+slot number in the frame)＝[(numberOfSlotsPerFrame×SFNstart time+slotstart time)+n×periodicity×numberOfSlotsPerFrame/10]modulo(1024×numberOfSlotsPerFrame)。其中，SFN表示无线系统帧号，numberOfSlotsPerFrame表示每个无线系统帧包含的时隙个数，slot number in the frame表示无线系统帧中的第几个时隙，n表示第n个SPS资源，periodicity表示SPS资源的周期，SFNstart time是指PDSCH起始发送的无线帧号，slotstart time是指PDSCH起始发送的时隙号。
用于释放SPS资源的DCI中的字段需满足下述条件：(1)CRC采用RRC信令中所提供的CS-RNTI进行加扰。(2)HARQ Process Number全置‘0’。(3)NDI全置‘0’；当配置了多个SPS时，HARQ Process Number将不是全置‘0’，而是指示激活的SPS资源对应的HARQ Process Number。(4)RV全置‘0’。(5)MCS全置‘1’。(6)FDRA全置‘1’(特殊场景全置‘0’)。
4.配置授权(configured grant，CG)
CG是指网络设备通过RRC信令或PDCCH分配指定一次用于上行传输的时频资源，网络设备和终端设备可以周期性地重复使用该时频资源进行上行传输。CG可应用于具有周期性传输这一特性的业务的上行传输中，例如CG可应用于XR业务或视频业务的上行传输中。另外，基于CG配置的用于进行上行传输的时频资源还可以称为CG资源，采用CG资源进行的上行传输还可以称为CG传输。
CG包括类型1和类型2。类型1中由RRC信令携带CG的相关参数，同时该RRC信令还用于激活CG资源。类型2与采用SPS配置SPS资源的方式类似，由RRC信令携带CG的相关参数，通过PDCCH来激活CG资源。在类型1和类型2的CG中，RRC信令中携带的CG的相关参数可由RRC信令中CG配置(即CG-Config)中的一个或多个字段来指示。下面对这两种类型的CG分别进行阐述。
结合图4，图4展示了类型1的CG流程。具体地，网络设备可在RRC信令中携带CG的相关参数以配置CG资源的周期性，RRC信令中携带的CG的相关参数可包括：CS-RNTI、CG周期、CG资源(包括时域资源和频域资源)、HARQ Process Number以及偏移值、MCS的具体数值、重复次数等。终端设备可根据接收的RRC信令确定周期性生效的CG资源，并在这些CG资源上周期性地向网络设备发送物理上行共享信道(physical uplink shared channel，PUSCH)。如果网络设备需对CG的相关参数进行更新，还可再次向终端设备发送RRC信令来指示更新后的参数，从而网络设备和终端设备可采用参数更新后的CG资源进行上行传输。
结合图5，图5展示了类型2的CG流程。具体地，网络设备可在RRC信令中携带CG的相关参数，包括CS-RNTI、CG周期等；在配置了多个CG时，RRC信令中可以携带多个CG分别的相关参数，该多个CG可能对应不同的CG周期。网络设备还发送PDCCH，该PDCCH中携带了用于激活CG资源的DCI，该DCI指示了激活的CG资源中的频域资源以及MCS，该DCI的字段格式要求与SPS中用于激活SPS资源的DCI的格式要求类似，不再赘述。终端设备确定周期性生效的CG资源所在的时隙，并在这些CG资源上向网络设备发送PUSCH。如果需要释放CG资源(也可称为去激活CG资源)，网络设备需再次发送PDCCH，该PDCCH中携带了用于释放CG资源的DCI，该DCI指示了需要释放的CG资源，该DCI的格式要求与SPS中用于释放SPS资源的DCI的格式要求类似，不再赘述。如果要再次使用已被释放的CG资源，网络设备需重新发送用于激活CG资源的DCI，以再次激活CG资源，终端设备可采用再次激活的CG资源向网络设备发送PUSCH。另外，关于CG的参数更新的具体阐述可参见类型1中的相关阐述，不再赘述。
5.时间窗
本申请实施例中，一个时间窗由一个或多个时间单元组成。时间单元可以是一个或多个帧(frame)，一个或多个子帧(sub frame)，一个或多个时隙(slot)，一个或多个微时隙，一个或多个符号等。其中，符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号、离散傅里叶变换扩频的正交频分复用(discrete fourier transform spread spectrum orthogonal frequency division multiplexing，DFT-S-OFDM)符号等。另外，时间单元还可以是毫秒、秒、子帧、迷你时隙和符号中的至少一项。其中，迷你时隙由多个符号构成。
另外，本申请实施例中，时间窗的时长是指该时间窗的起始位置至该时间窗的结束位置这一时段的时长。时间窗用于数据传输说明该时间窗配置了用于数据传输的资源，在时间窗进行数据传输是指在该时间 窗配置的资源上进行数据传输。例如，数据传输是SPS传输时，时间窗用于数据传输说明该时间窗配置了SPS资源，在时间窗进行数据传输是指在该时间窗配置的SPS资源上进行数据传输。又例如，数据传输是CG传输时，时间窗用于数据传输说明该时间窗配置了CG资源，在时间窗进行数据传输是指在该时间窗配置的CG资源上进行数据传输。
6.SPS栅格(Raster)、CG Raster
SPS Raster用于表征每个周期内的一个时段划分为多个时间窗，该多个时间窗中的至少一个时间窗用于SPS传输。CG Raster用于表征每个周期内的一个时段划分为多个时间窗，该多个时间窗中的至少一个时间窗用于CG传输。其中，用于划分为多个时间窗的时段可以是抖动范围所表示的时段。
SPS Raster和CG Raster可采用比特位图(bitmap)表示。SPS Raster的比特位图(即SPS Raster Bitmap)可表示一个周期内用于SPS传输的时间窗在多个时间窗中的位置分布情况，多个周期中不同周期内用于SPS传输的时间窗在多个时间窗中的位置分布相同。SPS Raster Bitmap中每个比特位与多个时间窗中至少一个时间窗对应，比特位的值为“0”时表征了该比特位对应的时间窗不用于数据传输，比特位的值为“1”时表征了该比特位对应的时间窗用于数据传输。CG Raster的比特位图(即CG Raster Bitmap)与SPS Raster Bitmap类似，不再赘述。
例如，结合图6，在周期为16.67ms的一个周期内，抖动范围的时长为8ms(如图6中的0ms至8ms这一抖动范围)，时隙长度为0.5ms，可将8ms的时段划分为时长均为0.5ms的16个时间窗，将该16个时间窗中0.5ms至1ms、1.5ms至2ms、2.5ms至3ms、3.5ms至4ms、4ms至4.5ms、4.5ms至5ms、5.5ms至6ms、6.5ms至7ms、7.5ms至8ms这9个时间窗配置为用于数据传输的时间窗，也就是说该9个时间窗为SPS资源生效的时间窗，图6中采用灰色矩形框表示的时间窗为用于数据传输的时间窗。那么，SPS Raster Bitmap为[0,1,0,1,0,1,0,1,1,1,0,1,0,1,0,1]，该16个比特位按照从前到后的顺序与按照时间从先到后排列的16个时间窗一一对应。
另外，在时分双工(time division duplexing，TDD)系统中，定义了每个时隙能够用于上行传输还是用于下行传输，SPS资源需要配置在能够用于下行传输的时隙(即D slot)上，CG资源需要配置在能够用于上行传输的时隙(即U slot)上，因此SPS Raster或CG Raster还需要基于每个时隙能够用于上行传输还是用于下行传输进行调整。具体地，如果在SPS Raster中某U slot被配置为用于进行SPS传输，需将该U slot调整为不用于进行SPS传输，且将位于该U slot之后且最接近于该U slot的一个D slot配置为用于进行SPS传输的D slot；在进行SPS传输的过程中采用的是调整后的SPS Raster。如果在CG Raster中某D slot被配置为用于进行CG传输，将该D slot调整为不用于进行CG传输，且将位于该D slot之后且最接近于该D slot的一个U slot配置为用于进行CG传输的U slot；在进行CG传输的过程中采用的是调整后的CG Raster。
例如，存在16个slot，其中，第2、3、5、6、7、8、10、11、12、13、15、16个slot为D slot，第4、9、14个slot为U slot。SPS Raster Bitmap为[0,1,0,1,0,1,0,1,1,1,0,1,0,1,0,1]，该SPS Raster Bitmap表示了该16个slot中每个slot是否用于SPS传输。可见，第4个slot为U slot但被配置为用于进行SPS传输的slot，因此将第4个slot调整为不用于进行SPS传输，而第5个slot是位于第4个slot之后且最接近于第4个slot的一个D slot，因此将第5个slot从不用于进行SPS传输调整为用于进行SPS传输。第9个slot为U slot被配置为用于进行SPS传输的slot，因此将第9个slot调整为不用于进行SPS传输，而第10个slot是位于第9个slot之后且最接近于第9个slot的一个D slot，且第10个slot本就被配置为用于进行SPS传输的slot，因此不对第10个slot进行调整。类似地，将第14个slot调整为不用于进行SPS传输，且将第15个slot从不用于进行SPS传输调整为用于进行SPS传输。基于上述调整，调整后的SPS Raster Bitmap为[0,1,0,0,1,1,0,1,0,1,0,1,0,0,1,1]。
7.平均调度时延(average delay)
SPS Raster或CG Raster的平均调度时延满足以下的公式(1)：
其中，N是SPS Raster或CG Raster中将时段划分得到的时间窗总个数；pi是数据在N个时间窗中的第i个时间窗到达的概率；di是N个时间窗中第i个时间窗对应的调度时延，即数据在N个时间窗中第i个时间窗到达时，能够用于传输该数据包的时间窗相比于第i个时间窗的时延，可表示为两者相差的时间窗个数。
例如，视频帧的抖动服从均值为0、标准差为2ms的截断高斯分布，抖动范围为[-4ms，4ms]，时隙长 度为0.5ms。将抖动范围这一时段划分为时长均为0.5ms的16个时间窗，视频帧在该16个时间窗中每个时间窗可能到达的概率为P＝[p1,p2,…,p16]＝[0.0401,0.0267，0.0388,0.0531,0.0679,0.0819,0.0928,0.0987,0.0987,0.0928,0.0819,0.0679,0.0531,0.0388,0.0267,0.0401]，如图7所示。如果SPS Raster Bitmap为[0,0,0,1,0,1,0,1,1,1,0,1,0,0,0,1]，16个时间窗分别对应的调度时延为d＝[d1,d2,…,d16]＝[3,2,1,0,1,0,1,0,0,0,1,0,3,2,1,0]，将P和d代入公式(1)可得到平均调度时延为0.7187个时间窗，即平均调度时延等于0.7187×0.5ms＝0.3594ms。
针对XR业务或视频业务中存在抖动的数据，在每个周期内，如果SPS资源或CG资源被配置在预期时间之前，在数据晚于预期时间到达时会错过当前周期内的SPS资源或CG资源，需采用下一周期内的SPS资源或CG资源上传输，导致传输数据的时延较大。如果SPS资源或CG资源被配置在预期时间之后，在数据早于预期时间到达网络设备时，需等待一段时间直至配置了SPS资源或CG资源的时间才能传输数据，导致传输数据的时延较大。
本申请实施例提供一种数据传输方法，该方法中，终端设备接收来自网络设备的第一信息；终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗，并在M个时间窗中的Y个时间窗与网络设备进行数据传输；其中，N为大于1的整数，M是小于N的正整数，Y是小于M的正整数。基于该方法，数据提前于预期时间到达时可在靠前的用于数据传输的时间窗进行数据传输，数据延后于预期时间到达时可在靠后的用于数据传输的时间窗进行数据传输，有利于减少传输数据的时延。并且，该方法中用于数据传输的M个时间窗可在一个SPS/CG中配置，M的取值可以不受配置的SPS/CG个数的限制，从而在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延。另外，用于数据传输的时间窗由一个SPS/CG进行配置这一方式还可以减少为激活用于数据传输的时间窗而交互的信令开销。
以下结合附图对本申请实施例进行详细阐述。本申请中的流程示意图以网络设备和终端设备作为该交互示意的执行主体为例来示意相应的方法，但本申请并不限制交互示意的执行主体。例如，图中的网络设备也可以是支持该网络设备实现相应方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图中的终端设备也可以是支持该终端设备实现相应方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。
请参阅图8，图8是本申请实施例提供的一种数据传输方法的流程示意图，该数据传输方法从网络设备与终端设备交互的角度进行阐述，该数据传输方法包括以下步骤：
S101、网络设备向终端设备发送第一信息；该第一信息用于配置在第一时段的N个时间窗中用于数据传输的M个时间窗；N为大于1的整数，M是小于N的正整数。相应的，终端设备接收来自网络设备的第一信息。
可选的，第一时段可以是数据的抖动范围；第一时段的N个时间窗可以是将第一时段进行划分得到的N个时段，该N个时间窗中每个时间窗的时长可以均等于时隙长度。例如，数据的抖动范围为0ms至4ms，时隙长度为0.5ms，那么可将0ms至4ms这一时段划分为时长均等于0.5ms的8个时间窗，该8个时间窗分别为：0ms至0.5ms、0.5ms至1ms、1ms至1.5ms、1.5ms至2ms、2ms至2.5ms、2.5ms至3ms、3ms至3.5ms、3.5ms至4ms。
该方式应用于XR业务或视频业务时，每个周期内分别存在第一时段和第一时段的N个时间窗，每个周期内的第一时段是该周期内数据的抖动范围，每个周期内第一时段划分得到的时间窗个数即N的取值相同。例如，XR业务或视频业务中数据的周期为16.67ms，第一个周期为0ms至16.67ms这一时段，第二个周期为16.67ms至33.34ms，第一个周期内数据的抖动范围为0ms至8ms，第二个周期内数据的抖动范围为16.67ms至24.67ms；那么，第一个周期内的第一时段为0ms至8ms这一时段，第一个周期内第一时段的N个时间窗是将0ms至8ms这一时段进行划分得到的；第二个周期内的第一时段为16.67ms至24.67ms这一时段，第二个周期内第一时段的N个时间窗是将16.67ms至24.67ms这一时段进行划分得到的。
可选的，用于数据传输的M个时间窗包括N个时间窗中的最后一个时间窗。该方式能够确保数据即使在N个时间窗中的最后一个时间窗到达，网络设备和终端设备之间也可以在N个时间窗的范围内传输数据。该方式应用于XR业务或视频业务时可确保每个周期内的数据能够在该周期内传输，减少由于每个周期内在数据到达时/之后无用于数据传输的时间窗导致无法在该周期内传输数据而对数据的传输性造成的影响。
本申请实施例中，N个时间窗中的最后一个时间窗是指N个时间窗中时域位置最靠后的一个时间窗。另外，后文中提及的N个时间窗中的第j个时间窗是指N个时间窗中时域位置排在第j位的时间窗，j为小于或等于N的正整数，后文不再赘述。
本申请实施例中，数据传输可以是下行传输，例如数据传输是SPS传输；数据传输也可以是上行传输，例如数据传输是CG传输。在数据传输是下行传输的情况下，对于网络设备来说，网络设备与终端设备的数据传输包括：网络设备等待向终端设备发送数据以及向终端设备发送该数据；对于终端设备来说，网络设备与终端设备的数据传输包括：终端设备监听来自网络设备的数据以及接收来自网络设备的该数据。在数据传输是上行传输的情况下，对于终端设备来说，网络设备与终端设备的数据传输包括：终端设备等待向网络设备发送数据以及向网络设备发送该数据；对于网络设备来说，网络设备与终端设备的数据传输包括：网络设备监听来自终端设备的数据以及接收来自终端设备的该数据。
在SPS传输中，网络设备等待向终端设备发送数据是因为网络设备需要监听并接收来自服务器的数据，在接收了来自服务器的数据之后才能将该数据发送给终端设备。在CG传输中，终端设备等待向网络设备发送数据是因为终端设备针对该数据存在编码处理时延，终端设备在编码完成后才能将该数据发送给网络设备。
S102、终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗。
在一种可选的实施方式中，第一信息用于指示比特位图；该比特位图中每个比特位与N个时间窗中至少一个时间窗相对应，每个比特位的值用于表征该比特位对应的时间窗是否用于数据传输。其中，数据传输是SPS传输时，第一信息所指示的比特位图可以是SPS Raster Bitmap；数据传输是CG传输时，第一信息所指示的比特位图可以是CG Raster Bitmap。相应的，终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗，可包括：终端设备从第一信息所指示的比特位图中确定用于数据传输的M个时间窗。
可选的，比特位的值可采用“0”、“1”来表征该比特位对应的时间窗是否用于数据传输。例如，比特位的值为“1”时该比特位对应的时间窗用于数据传输，比特位的值为“0”时该比特位对应的时间窗不用于数据传输；或者，比特位的值为“1”时该比特位对应的时间窗不用于数据传输，比特位的值为“0”时该比特位对应的时间窗用于数据传输。另外，比特位的值还可以采用其他的表示方式，例如比特位的值为“true”时表示该比特位对应的时间窗用于数据传输，比特位的值为“false”时表示该比特位对应的时间窗不用于数据传输，不作限制。为便于阐述，后文中采用比特位图的值为“1”时该比特位对应的时间窗用于数据传输、比特位图的值为“0”该比特位对应的时间窗不用于数据传输为例进行阐述，后文不再赘述。
例如，N等于16，比特位图包括16个比特位，该16个比特位与第一时段的16个时间窗一一对应；该16个比特位的值分别为0、0、0、1、0、1、0、1、1、1、0、1、0、0、0、1，那么，比特位图表示为[0,0,0,1,0,1,0,1,1,1,0,1,0,0,0,1]。可见，在16个时间窗中，第4、6、8、9、10、12、16个时间窗用于数据传输，其余的时间窗不用于数据传输。
又例如，N等于8，比特位图包括4个比特位，该4个比特位中每个比特位与第一时段的8个时间窗中相邻的两个时间窗对应，具体地，比特位#1与时间窗#1和时间窗#2对应，比特位#2与时间窗#3和时间窗#4对应，比特位#3与时间窗#5和时间窗#6对应，比特位#4与时间窗#7和时间窗#8对应。比特位#1至比特位#4的值分别为0、1、0、1，那么比特位图表示为[0,0,1,1,0,0,1,1]，可见，在8个时间窗中，第3、4、7、8个时间窗用于数据传输，第1、2、5、6个时间窗不用于数据传输。
为便于阐述，后文中以比特位图中每个比特位与一个时间窗相对应为例进行阐述，后文不再赘述。
可选的，第一信息所指示的比特位图可以是基于数据的抖动范围以及抖动服从的概率分布从预先定义的多个比特位图中确定的。该多个比特位图可以是针对抖动范围不同、抖动服从的概率分布不同的数据预定义的。其中，数据的抖动范围不同、抖动服从的概率分布不同可能是由于数据的业务类型不同以及服务器编解码能力不同所形成的，数据的业务类型不同可表示为数据的帧率不同，例如，帧率可以是30FPS、60FPS、120FPS等。本申请实施例提供了示例性的表1，表1表征了预先定义的多个比特位图以及每个比特位图对应的索引、M/N、平均调度时延。
表1

在第一时段等于抖动范围，并且第一时段的N个时间窗中每个时间窗的时长均等于时隙长度(该时隙长度为0.5ms)时，表1中索引0至索引3分别对应的比特位图可适用于抖动范围为8ms的数据；索引4至索引7分别对应的比特位图可适用于抖动范围为4ms的数据；索引8和索引9分别对应的比特位图可适用于抖动范围为2ms的数据。
另外，第一信息指示比特位图可以是间接指示的，也可以是直接指示的。其中，在第一信息间接指示比特位图的情况下，第一信息可以是比特位图的索引；终端设备在获取了比特位图的索引之后，还需从预先定义的多个比特位图中确定该索引对应的比特位图，进而根据该索引对应的比特位图确定用于数据传输的M个时间窗。在第一信息直接指示比特位图的情况下，第一信息可以是比特位图，也就是说网络设备可直接将比特位图告知给终端设备，终端设备直接根据接收到的比特位图确定用于数据传输的M个时间窗。
在另一种可选的实施方式中，第一信息用于配置M的取值；M个时间窗在N个时间窗中的位置是预定义的。在该实施方式下，可以预定义用于数据传输的时间窗在N个时间窗中的位置分布方式，那么，终端设备在获取了M的取值即用于数据传输的时间窗的总个数之后，可以根据预定义的位置分布方式，在第一时段的N个时间窗中确定用于数据传输的M个时间窗。
可选的，预定义的位置分布方式为：用于数据传输的M个时间窗中相邻的任意两个时间窗的起始位置之间的间隔相同且该间隔等于第一值，该第一值是将N除以M得到的值进行向上取整得到的，第一值表示为时间窗的个数。也就是说，N除以M得到的值是整数时M个时间窗在N个时间窗中的位置是均匀分布，N除以M得到的值是非整数时M个时间窗在N个时间窗中的位置是近似均匀分布的。另外，在用于数据传输的M个时间窗包括N个时间窗中的最后一个时间窗的情况下，可先将N个时间窗中的最后一个时间窗确定为M个时间窗中的最后一个时间窗，再以该最后一个时间窗为基准，根据均匀分布(或近似均匀分布)的位置分布方式确定位于该最后一个时间窗之前的、用于数据传输的时间窗。
例如，第一信息配置了M的取值为8，第一时段的时长为8ms，可将第一时段划分为时长均为0.5ms的16个时间窗(即N取值为16)；用于数据传输的8个时间窗包括16个时间窗中的最后一个时间窗，再根据均匀分布的位置分布方式，可确定第一值为2个时间窗即第一值等于1ms，那么以16个时间窗中的最后一个时间窗为基准，可确定用于数据传输的8个时间窗除了16个时间窗中的最后一个时间窗，还包括16个时间窗中的第2、4、6、8、10、12、14个时间窗，16个时间窗中用于数据传输的8个时间窗对应的比特位图可表示为[0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1]。
又例如，第一信息配置了M的取值为3，第一时段的时长为8ms，可将第一时段划分为时长均为0.5ms的16个时间窗(即N取值为16)；用于数据传输的3个时间窗包括16个时间窗中的最后一个时间窗，再根据近似均匀分布的位置分布方式，可确定第一值为6个时间窗即第一值等于3ms，那么以16个时间窗中的最后一个时间窗为基准，可确定用于数据传输的3个时间窗除了16个时间窗中的最后一个时间窗，还包括16个时间窗中的第4、10个时间窗，16个时间窗中用于数据传输的3个时间窗对应的比特位图可表示为[0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,1]。
可选的，预定义的位置分布方式为：用于数据传输的M个时间窗包括多个第二时段中每个第二时段内与该第二时段的起始位置相距f个时间窗的连续g个时间窗，该多个第二时段是将第一时段均匀划分得到的且每个第二时段的时长等于x，每个第二时段包括第一时段的N个时间窗中的至少两个时间窗。其中，x为正数，f为大于或等于0的整数，g为正整数。x、f、g的取值可以是网络设备发送给终端设备的，也可以是网络设备与终端设备协商确定的。另外，该实施方式下，网络设备还可以不配置M的取值，而第一信息用于配置x、f、g的取值。
例如，结合图9，第一时段的时长为8ms，x等于2ms，f等于2，g等于2，M等于8；第一时段的16个时间窗(即N等于16)中每个时间窗的时长等于0.5ms。第一时段划分为时长均为2ms的4个第二时段，包括：第二时段#1、第二时段#2、第二时段#3和第二时段#4，该4个第二时段依次包括16个时间窗中的 第1个时间窗至第4个时间窗、第5个时间窗至第8个时间窗、第9个时间窗至第12个时间窗、第13个时间窗至第16个时间窗。那么，用于数据传输的8个时间窗包括：4个第二时段中每个第二时段内与该第二时段的起始位置相距2个时间窗的连续2个时间窗，即用于数据传输的8个时间窗包括16个时间窗中的第3、4、7、8、11、12、15、16个时间窗，16个时间窗中用于数据传输的8个时间窗对应的比特位图可表示为[0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1]，图9中灰色矩形框表示的时间窗为用于数据传输的时间窗。
在一种可选的实施方式中，该方法还包括：网络设备向终端设备发送第四信息，该第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。该实施方式可使得终端设备获知第一时段的时长，有利于终端设备从第一时段的N个时间窗中确定用于数据传输的M个时间窗。
S103、终端设备在M个时间窗中的Y个时间窗与网络设备进行数据传输；Y是小于M的正整数。
例如，数据传输是下行的，M等于8，用于数据传输的8个时间窗在第一时段的16个时间窗中的位置如图10所示，图10中灰色矩形框表示的时间窗为用于数据传输的时间窗。图10中，用于数据传输的8个时间窗包括：时间窗#1、时间窗#4、时间窗#6、时间窗#8、时间窗#9、时间窗#11、时间窗#13和时间窗#16。对于网络设备来说，网络设备在时间窗#1等待向终端设备发送数据，在t1接收到来自服务器的数据，在时间窗#4、时间窗#6和时间窗#8向终端设备发送该数据。对于终端设备来说，终端设备在时间窗#1监听来自网络设备的数据，在时间窗#4、时间窗#6和时间窗#8接收来自网络设备的数据。可见，终端设备和网络设备之间在用于数据传输的8个时间中的4个时间窗进行数据传输。
在一种可选的实施方式中，该方法还包括：终端设备在M个时间窗中除Y个时间窗之外的M-Y个时间窗不与网络设备进行数据传输。也就是说，网络设备和终端设备可以释放(/去激活)M个时间窗中除Y个时间窗之外的M-Y个时间窗的资源。该实施方式可应用于在Y个时间窗完成了数据传输，那么剩余的M-Y个时间窗可用于其他使用，例如用于其他用户数据传输，有利于提升通信系统整体的吞吐量。例如，结合图10，网络设备和终端设备之间在时间窗#1、时间窗#4、时间窗#6和时间窗#8进行数据传输，那么可以释放用于数据传输的8个时间窗中剩余的时间窗#9、时间窗#11、时间窗#13和时间窗#16。
并且，该方式无需网络设备额外发送信令(如DCI)来指示释放该M-Y个时间窗，能够节省信令开销。另外，该方式应用于XR业务或视频业务时，某周期内的M-Y个时间窗被释放的操作不会影响位于该周期之后的其他周期内的时间窗的激活状态，也无需网络设备额外发送信令(如DCI)来指示激活位于该周期之后的其他周期内的时间窗，节省了信令开销。
例如，以数据传输是SPS传输、SPS周期为16.67ms为例，结合图11，图11中A部分、B部分、C部分分别展示了同一时域上的数据分布情况、配置8个SPS且每个SPS在每个周期内配置1个slot为SPS资源时的SPS资源分布情况、基于本申请提供的数据传输方法由1个SPS配置用于数据传输的M个时间窗时的SPS资源分布情况。在B部分中，采用8种不同填充图案的矩形框来表示由8个SPS(依次为SPS#1至SPS#8)配置的SPS资源，不同周期内相同填充图案的矩形框表示的SPS资源由同一个SPS配置。在C部分中，第一时段为数据的抖动范围，每个时间窗的时长等于时隙长度；图中采用矩形框表示由一个SPS在每个周期内第一时段的16个时间窗中配置了用于数据传输的8个时间窗，即由一个SPS在每个周期内配置了8个SPS资源；灰色的矩形框表示激活的SPS资源，白色的矩形框表示释放的SPS资源。另外，图11中向下的实线单箭头表示网络设备会发送DCI。
结合图11，C部分中由1个SPS来配置SPS资源，网络设备发送一个DCI，该DCI用于激活1个SPS对应的全部SPS资源，与B部分中配置了8个SPS使得网络设备需针对8个SPS中每个SPS分别发送一个DCI来激活每个SPS对应的SPS资源的方式相比，能够节省信令开销。并且，在t3至t4的范围内，数据#2采用前4个SPS资源可完成传输，在C部分中，终端设备在数据传输完成时可直接释放该周期内剩余的后4个SPS资源，无需网络设备发送额外的用于释放SPS资源的DCI；与B部分中需要网络设备发送DCI来指示终端设备释放SPS资源的方式相比，节省了信令开销。另外，在C部分中，终端设备释放了第二个周期内的后4个SPS资源不会对后面周期中的SPS资源造成影响，即后面周期中的SPS依然是激活的，相比于B部分中为了释放第二个周期内SPS#4至SPS#8对应的SPS资源而发送的DCI会使得SPS#4至SPS#8在每个周期内对应的全部SPS资源均被释放，会导致如果要再次使用SPS#4至SPS#8对应的SPS资源需要网络设备再次发送一个DCI来激活SPS#4至SPS#8对应的SPS资源，C部分中的信令开销更小。
可选的，数据传输是SPS传输时，网络设备可在第一时段内的数据传输完成时/之后，确定在M-Y个时间窗不与终端设备进行数据传输。网络设备还可向终端设备发送第二信息，该第二信息用于指示第一时段内的数据传输的完成。相应的，终端设备可根据第二信息，确定在M-Y个时间窗不与网络设备进行数 据传输。可选的，第二信息是终端设备在Y个时间窗中的最后一个时间窗接收到的。也就是说网络设备可以在Y个时间窗中的最后一个时间窗向终端设备发送第二信息以告知终端设备：第一时段内的数据传输已完成，进而终端设备可以释放M个时间窗中剩余的M-Y个时间窗。该M-Y个时间窗可用于其他使用，例如用于其他用户数据传输，有利于提升通信系统整体的吞吐量。
可选的，数据传输是CG传输时，终端设备可在第一时段内的数据传输完成时/之后，确定在M-Y个时间窗不与网络设备进行数据传输。终端设备还可向网络设备发送第三信息，该第三信息用于指示第一时段内的数据传输的完成。相应的，网络设备可根据第三信息，确定在M-Y个时间窗不与终端设备进行数据传输。可选的，第三信息是网络设备在Y个时间窗中的最后一个时间窗接收到的。也就是说终端设备可以在Y个时间窗中的最后一个时间窗向网络设备发送第三信息以告知网络设备：第一时段内的数据传输已完成，进而网络设备可以释放M个时间窗中剩余的M-Y个时间窗。该M-Y个时间窗可用于其他使用，例如用于其他用户数据传输，有利于提升通信系统整体的吞吐量。
另外，第二信息是终端设备在Y个时间窗中的最后一个时间窗接收到的，和/或，第三信息是网络设备在Y个时间窗中的最后一个时间窗接收到的时，第二信息和/或第三信息还可以称为尾包信息。示例性地，在SPS传输中，第二信息可以携带于网络设备在Y个时间窗中的最后一个时间窗向终端设备发送的数据中，由媒体介入控制层控制单元(media access controlcontrol element，MAC CE)的控制层控制单元(media access control，MAC)子头中的部分或全部预留比特(例如“R域”中的预留比特)承载。例如，当1个预留比特被设置为“1”时，说明该MAC CE承载了第二信息，也就是说第一时段内的数据传输完成；当该预留比特被设置为“0”时，说明该MAC CE未承载第二信息，也就是说第一时段内的数据传输还未完成。又例如，当1个预留比特被设置为“0”时，说明该MAC CE承载了第二信息；当该预留比特被设置为“1”时，说明该MAC CE未承载第二信息。通过这种方式，无需引入新的MAC CE，且无需引入额外的指示开销。另外，CG传输中的第三信息与SPS传输中的第二信息类似，第三信息可以携带于终端设备在Y个时间窗中的最后一个时间窗向网络设备发送的数据中，由MAC CE的MAC子头中的部分或全部预留比特(例如“R域”中的预留比特)承载，不再赘述。
在另一种可选的实施方式中，Y可以等于M，也就是说网络设备与终端设备在M个时间窗均进行数据传输。例如，结合图12，数据传输是下行的，M等于8，图12中用于数据传输的M个时间窗在第一时段的N个时间窗中的位置分布与图10相同，图12中灰色矩形框表示的时间窗为用于数据传输的时间窗。对于网络设备来说，网络设备在时间窗#1、时间窗#4、时间窗#6、时间窗#8和时间窗#9均等待向终端设备发送数据，在t2接收到来自服务器的数据，在时间窗#11、时间窗#13和时间窗#16向终端设备发送该数据。对于终端设备来说，终端设备在时间窗#1、时间窗#4、时间窗#6、时间窗#8和时间窗#9均监听来自网络设备的数据，在时间窗#11、时间窗#13和时间窗#16接收来自网络设备的数据。可见，网络设备和终端设备之间在用于数据传输的8个时间窗均进行数据传输。
综上所述，该方法中，终端设备接收来自网络设备的第一信息；终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗，并在M个时间窗中的Y个时间窗与网络设备进行数据传输；其中，N为大于1的整数，M是小于N的正整数，Y是小于M的正整数。该方法中，数据提前于预期时间到达时可在靠前的用于数据传输的时间窗进行数据传输，数据延后于预期时间到达时可在靠后的用于数据传输的时间窗进行数据传输，有利于减少数据传输时延。并且，该方法中用于数据传输的M个时间窗可在一个SPS/CG中配置，M的取值可以不受配置的SPS/CG个数的限制，也就是说用于数据传输的时间窗个数可以不受SPS/CG个数的限制，从而在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延。另外，用于数据传输的M个时间窗由一个SPS/CG进行配置这一方式还可以减少为激活用于数据传输的时间窗的信令开销。
本申请实施例提供的数据传输方法中数据传输可以是SPS传输，还可以是CG传输，下面对数据传输是SPS传输和CG传输这两种情况下的数据传输方法分别进行阐述。
请参阅图13，图13是本申请实施例提供的一种SPS传输时的数据传输方法的示意图，该方法从网络设备和终端设备之间交互的角度进行阐述，该方法可以包括以下步骤：
S201、网络设备向终端设备发送第一信息，该第一信息用于配置第一时段的N个时间窗中用于数据传输的M个时间窗；相应的，终端设备接收来自网络设备的第一信息。
在一种可选的实施方式中，第一信息是比特位图的索引。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。可选的，第一信息可携带于RRC信令中的SPS-Config中。具体地，可以在SPS-Config 中添加SPS Raster索引字段(即sps-RasterIndex字段)，该字段用于承载比特位图的索引的值。
在一种可选的实施方式中，第一信息是比特位图；该方法还包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
可选的，第一信息是比特位图的情况下，第一信息和第四信息可携带于RRC信令中的SPS-Config中。具体地，可以在SPS-Config中添加SPS Raster时长字段(即sps-RasterTimer字段)和SPS Raster Bitmap字段(即sps-RasterBitMap字段)。其中，sps-RasterTimer字段用于承载第一时段的时长，第一时段可以是数据的抖动范围。sps-RasterBitMap字段用于承载比特位图，也就是说sps-RasterBitMap字段可用于表征第一时段的N个时间窗中每个时间窗是否用于数据传输。
在一种可选的实施方式中，第一信息用于配置M的取值；该方法还包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。另外，预定义的位置分布方式可以为：用于数据传输的M个时间窗在N个时间窗中的位置是均匀分布或近似均匀分布的。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
可选的，第一信息用于配置M的取值的情况下，第一信息和第四信息可携带于RRC信令中的SPS-Config中。具体地，可以在SPS-Config中添加sps-RasterTimer字段和SPS Raster数量字段(即sps-RasterNum字段)。其中，sps-RasterTimer字段用于承载第一时段的时长，第一时段可以是数据的抖动范围。sps-RasterNum字段用于承载M的取值，sps-RasterNum字段还用于表示在每个sps-RasterTimer的时段内用于数据传输的时间窗是均匀分布的或近似均匀分布的。
在一种可选的实施方式中，第一信息用于配置x、f、g的取值；该方法还包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。另外，预定义的位置分布方式可以为：用于数据传输的M个时间窗包括多个第二时段中每个第二时段内与该第二时段的起始位置相距f个时间窗的连续g个时间窗，该多个第二时段是将第一时段均匀划分得到的且每个第二时段的时长等于x，每个第二时段包括第一时段的N个时间窗中的至少两个时间窗。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
可选的，第一信息用于配置x、f、g的取值的情况下，第一信息和第四信息可携带于RRC信令中的SPS配置(SPS-Config)中。具体地，可以在SPS-Config中添加sps-RasterTimer字段、SPS Raster周期字段(即sps-RasterCycle字段)、SPS Raster周期-连续时隙字段(即sps-RasterCycle-nrofSlots字段)和SPS Raster周期-时隙偏移字段(即sps-RasterCycle-Slotoffset字段)。
其中，sps-RasterTimer字段用于承载第一时段的时长，第一时段可以是数据的抖动范围。sps-RasterCycle字段用于承载x的取值，也可以说sps-RasterCycle字段用于表征sps-RasterTimer的范围内的循环周期。sps-RasterCycle-nrofSlots字段用于承载g的取值，也就是说sps-RasterCycle-nrofSlots字段表征了sps-RasterTimer的范围内的每个循环周期内用于数据传输的连续的时间窗个数。sps-RasterCycle-Slotoffset字段用于承载f的取值，也可以说sps-RasterCycle-Slotoffset字段表征了sps-RasterTimer的范围内的每个循环周期内用于数据传输的第1个时间窗的起始位置相对于该循环周期的起始位置的偏移量。
S202、终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗。对于网络设备来说，数据传输包括等待向终端设备发送数据以及向终端设备发送数据；对于终端设备来说，数据传输包括监听来自网络设备的数据以及接收来自网络设备的数据。
S203、网络设备在M个时间窗中的Y个时间窗等待向终端设备发送数据以及向终端设发送数据，Y是小于M的正整数。相应的，S204、终端设备在M个时间窗中的Y个时间窗监听来自网络设备的数据以及接收来自网络设备的数据。
在一种可选的实施方式中，该方法还可包括：网络设备在第一时段内的数据传输的完成时/之后，释放M个时间窗中除Y个时间窗之外的M-Y个时间窗。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
在一种可选的实施方式中，该方法还可包括：网络设备在Y个时间窗中的最后一个时间窗向终端设备发送第二信息，第二信息用于指示第一时段内的数据传输的完成；终端设备根据接收到的第二信息，释放M个时间窗中除Y个时间窗之外的M-Y个时间窗具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
本申请对网络设备释放M-Y个时间窗的操作与网络设备向终端设备发送第二信息的操作的先后顺序不作限制。
另外，SPS传输时的数据传输方法还可以包括图8所示的数据传输方法中的实施方式，也存在对应的有益效果，不再赘述。
综上，在SPS传输中，用于数据传输的M个时间窗可以是由一个SPS配置的，M的取值可以不受配置的SPS个数的限制，在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延，还可以减少为激活用于数据传输的时间窗的信令开销。
请参阅图14，图14是本申请实施例提供的一种CG传输时的数据传输方法的示意图，该方法从网络设备和终端设备之间交互的角度进行阐述，该方法可以包括以下步骤：
S301、网络设备向终端设备发送第一信息，该第一信息用于配置第一时段的N个时间窗中用于数据传输的M个时间窗；相应的，终端设备接收来自网络设备的第一信息。
在一种可选的实施方式中，第一信息是比特位图的索引。可选的，第一信息可携带于RRC信令中的CG-Config中。具体地，可以在CG-Config中添加CG Raster索引字段(即cg-RasterIndex字段)，该字段用于承载比特位图的索引的值。
在一种可选的实施方式中，第一信息是比特位图；该方法还可以包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。
可选的，第一信息是比特位图的情况下，第一信息和第二信息可携带于RRC信令中的CG-Config中。具体地，可以在CG-Config中添加CG Raster时长字段(即cg-RasterTimer字段)和CG Raster Bitmap字段(即cg-RasterBitMap字段)。其中，cg-RasterTimer字段用于承载第一时段的时长，该第一时段可以是数据的抖动范围。cg-RasterBitMap字段用于承载比特位图，也就是说cg-RasterBitMap字段可用于表征第一时段的N个时间窗中每个时间窗是否用于数据传输。
在一种可选的实施方式中，第一信息用于配置M的取值；该方法还可以包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。另外，预定义的位置分布方式可以为：用于数据传输的M个时间窗在N个时间窗中的位置是均匀分布或近似均匀分布的。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
可选的，第一信息用于配置M的取值的情况下，第一信息和第四信息可携带于RRC信令中的CG-Config中。具体地，可以在CG-Config中添加cg-RasterTimer字段和CG Raster数量字段(即cg-RasterNum字段)。其中，cg-RasterTimer字段用于承载第一时段的时长，第一时段可以是数据的抖动范围。cg-RasterNum字段可用于承载M的取值，cg-RasterNum字段还用于表示在每个cg-RasterTimer的时段内用于数据传输的时间窗是均匀分布的或近似均匀分布的。
在一种可选的实施方式中，第一信息用于配置x、f、g的取值；该方法还可包括：网络设备向终端设备发送第四信息，第四信息用于配置第一时段的时长。相应的，终端设备接收来自网络设备的第四信息。另外，预定义的位置分布方式可以为：用于数据传输的M个时间窗包括多个第二时段中每个第二时段内与该第二时段的起始位置相距f个时间窗的连续g个时间窗，该多个第二时段是将第一时段均匀划分得到的且每个第二时段的时长等于x，每个第二时段包括第一时段的N个时间窗中的至少两个时间窗。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
可选的，第一信息用于配置x、f、g的取值的情况下，第一信息和第四信息可携带于RRC信令中的CG配置(CG-Config)中。具体地，可以在CG-Config中添加cg-RasterTimer字段、CG Raster周期字段(即cg-RasterCycle字段)、CG Raster周期-连续时隙字段(即cg-RasterCycle-nrofSlots字段)和CG Raster周期-时隙偏移字段(即cg-RasterCycle-Slotoffset字段)。
其中，cg-RasterTimer字段用于承载第一时段的时长，第一时段可以是数据的抖动范围。cg-RasterCycle字段用于承载x的取值，也可以说cg-RasterCycle字段用于表征cg-RasterTimer的范围内的循环周期。cg-RasterCycle-nrofSlots字段用于承载g的取值，也就是说cg-RasterCycle-nrofSlots字段表征了cg-RasterTimer的范围内的每个循环周期内用于数据传输的连续的时间窗个数。cg-RasterCycle-Slotoffset字段用于承载f的取值，也可以说cg-RasterCycle-Slotoffset字段表征了cg-RasterTimer的范围内的每个循环周期内用于数据传输的第1个时间窗的起始位置相对于该循环周期的起始位置的偏移量。
另外，在第一信息携带于CG-Config中，或者第一信息和第四信息均携带于CG-Config中的情况下，CG-Config中的CG连续时隙字段(即cg-nrofSlots字段)可以不生效，cg-nrofSlots字段用于指示用于数据传输的连续slot的个数。
S302、终端设备根据第一信息，在第一时段的N个时间窗中确定用于数据传输的M个时间窗。对于 终端设备来说，数据传输包括等待向网络设备发送数据以及向终端设备发送数据；对于网络设备来说，数据传输包括监听来自终端设备的数据以及接收来自终端设备的数据。
S303、终端设备在M个时间窗中的Y个时间窗等待向网络设备发送数据以及向网络设发送数据，Y是小于M的正整数。相应的，S304、网络设备在M个时间窗中的Y个时间窗监听来自终端设备的数据以及接收来自终端设备的数据。
在一种可选的实施方式中，该方法还可包括：终端设备在第一时段内的数据传输的完成时/之后，释放M个时间窗中除Y个时间窗之外的M-Y个时间窗。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
在一种可选的实施方式中，该方法还可包括：终端设备在Y个时间窗中的最后一个时间窗向网络设备发送第三信息，第三信息用于指示第一时段内的数据传输的完成；网络设备根据接收到的第三信息，释放M个时间窗中除Y个时间窗之外的M-Y个时间窗。具体阐述可参见图8所示的数据传输方法中的相关阐述，不再赘述。
本申请对终端设备释放M-Y个时间窗的操作与终端设备向网络设备发送第二信息的操作的先后顺序不作限制。
另外，CG传输时的数据传输方法还可以包括图8所示的数据传输方法中的其他实施方式，也存在对应的有益效果，不再赘述。
综上，在CG传输中，用于数据传输的M个时间窗可以是由一个CG配置的，M的取值可以不受配置的CG个数的限制，在数据的抖动范围较大时能够配置较多的用于数据传输的时间窗以应对数据的抖动，有利于减少传输数据的时延，还可以减少为激活用于数据传输的时间窗的信令开销。
另外，本申请实施例还针对信号传输的场景提供一种与图8所示的数据传输方法类似的方法，不同之处在于，在信号传输的场景中，第一信息用于配置在第一时段的N个时间窗中用于信号传输的M个时间窗。该方法可以在第一时段中配置多个用于信号传输的时间窗，在信号提前于预期时间到达时，终端设备可在靠前的用于信号传输的时间窗接收或发送信号；在信号延后于预期时间到达时，终端设备可在靠后的用于信号传输的时间窗接收或发送信号，有利于减少传输信号的时延。
具体地，网络设备可向终端设备发送第一信息；第一信息用于配置在第一时段的N个时间窗中用于信号传输的M个时间窗。终端设备接收来自网络设备的第一信息；根据第一信息，在第一时段的N个时间窗中确定用于信号传输的M个时间窗，并在M个时间窗中的Y个时间窗与网络设备进行信号传输；N为大于1的整数，M是小于N的正整数，Y是小于M的正整数。其中，信号可以是唤醒信号(wake up signal，WUS)，第一时段可以是WUS的监听范围，用于信号传输的M个时间窗可以是根据WUS的抖动服从的概率分布从N个时间窗中确定的。
在一种可选的实施方式中，该方法还包括：终端设备在M个时间窗中除Y个时间窗之外的M-Y个时间窗不与网络设备进行信号传输。可选的一种方式中，信号传输是下行传输；终端设备在M-Y个时间窗不与网络设备进行信号传输，包括：终端设备根据第二信息，确定在M-Y个时间窗不与网络设备进行信号传输；第二信息用于指示第一时段内的信号传输的完成。可选的，第二信息是在Y个时间窗中的最后一个时间窗接收到的。可选的另一种方式中，信号传输是上行传输；该方法还包括：终端设备在Y个时间窗中的最后一个时间窗向网络设备发送第三信息，第三信息用于指示第一时段内的信号传输的完成。
在一种可选的实施方式中，第一信息用于指示比特位图；比特位图中每个比特位与N个时间窗中至少一个时间窗相对应，每个比特位的值用于表征该比特位对应的时间窗是否用于信号传输。在另一种可选的实施方式中，第一信息用于配置M的取值；M个时间窗在N个时间窗中的位置是预定义的。
在一种可选的实施方式中，该方法还包括：接收来自网络设备的第四信息，第四信息用于配置第一时段的时长。
