Description

传输上行数据的方法和装置
本申请要求于2021年04月06日提交国家知识产权局、申请号为202110369072.3、申请名称为“一种通信方法、终端及网络设备”，以及，要求于2021年04月30日提交国家知识产权局、申请号为202110486195.5、申请名称为“传输上行数据的方法和装置”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，并且更具体地涉及通信领域中传输上行数据的方法和装置。
背景技术
在通信领域中，终端设备可以基于网络设备实时调度的资源向网络设备传输上行数据，或者终端设备基于网络设备配置的资源向网络设备传输上行数据。传输终端设备基于配置的资源传输上行数据的时延低于基于实时调度的资源传输上行数据的时延。因此，为了提高传输上行数据的时延，通常情况下，终端设备基于预先配置的资源传输上行数据。但是网络设备预先配置的资源可能满足不了终端设备传输上行数据的数据量需求，例如，网络设备预先配置的配置资源太小，终端设备传输的上行数据的数据量较大，则部分上行数据仍然需要通过实时调度的资源传输数据，导致传输部分上行数据传输时延较大；又例如，网络设备预先配置的资源比较大，终端设备传输的上行数据的数据量较小，则会导致资源浪费的情况。因此降低时延同时如何节省资源开销是亟待解决的问题。
发明内容
本申请实施例提供了一种传输上行数据的方法装置，能够降低时延，有助于节省资源。
第一方面，提供了一种传输上行数据的方法，方法适用于终端设备，方法包括：在配置的第一资源上向网络设备发送第一数据；向网络设备指示终端设备期望改变传输数据的资源大小；在配置的第二资源上向网络设备发送第二数据。
在上述方案中，终端设备可以在配置的第一资源上向网络设备发送第一数据，终端设备向网络设备指示终端设备期望改变传输数据的资源大小，终端设备在与第一资源的大小不同的第二资源上传输第二数据，针对不同的数据终端设备可以采用不同大小的资源传输，从而可以满足数据的传输需求，也能节省资源开销，并且终端设备在配置的第一资源上和第二资源上分别传输了第一数据和第二数据，避免网络设备需要实时调度资源，能够节省传输时延。
可选地，向网络设备指示终端设备期望改变传输数据的资源大小，包括：在第一时刻向网络设备指示终端设备期望改变传输数据的资源大小，第二数据为第一时刻以后到达终端设备的数据。也就是说终端设备期望改变的是未来到达的数据的资源大小。可选地，第二数据为第一时刻以后到达终端设备的数据可以理解为：第二数据为向网络设备指示终端设备期望改变传输数据的资源大小的第一时刻起的未来第一时间段内的数据，第一时间段 可以是已知的时间段或者为未知的时间段。
可选地，第一资源和第二资源为网络设备预先配置给终端设备的。
可选地，第一资源可以是网络设备预先配置给终端设备的，第二资源可以是终端设备向网络设备指示终端设备期望改变传输数据的资源大小之后网络设备配置的。
可选地，第一资源和第二资源为周期性资源，第一资源的资源周期与第二资源的周期可以相同或者不同，本申请实施例不予限制。
可选地，终端设备可以向网络设备发送消息或者发送第一指示信息来指示终端设备期望改变传输数据的资源大小，或者终端设备也可以向网络设备不发送任何消息指示终端设备期望改变传输数据的资源大小，例如网络设备接收到某一业务的第一数据，按照该业务的特征，网络设备能够继续接收该业务的数据，但是网络设备在预设时间段内没有接收到该业务的数据，则可能网络设备配置给终端设备的资源不符合终端设备的传输需求，因此，网络设备确定终端设备。
可选地，终端设备可以通过向网络设备请求资源(例如，通过SR或者BSR请求资源)来向网络设备指示终端设备期望改变传输数据的资源大小。换句话说，终端设备向网络设备请求资源，则网络设备获知配置给终端设备的资源不符合终端设备的传输需求，因此网络设备获知终端设备期望改变传输数据的资源大小。
可选地，第一数据和第二数据为同一种业务类型的数据。可选地，第一数据和第二数据的业务类型为XR业务，第一数据为XR业务的P帧数据，第二数据为XR业务的帧数据。
可选地，终端设备向网络设备指示终端设备期望改变传输数据的资源大小，可以替换为：终端设备向网络设备请求改变传输数据的资源大小，或者替换为：终端设备向网络设备指示终端设备需要改变传输数据的资源大小。
在一些可能的实现方式中，第一数据与第二数据的数据量不同；若第一数据的第一数据量大于第二数据的第二数据量，则第一资源的第一资源大小大于第二资源的第二资源大小；若第一数据量小于第二数据量，则第一资源大小小于第二资源大小。
在上述方案中，终端设备的数据量大，则采用的资源也大，终端设备的数据量小，则采用的资源也小，这样，可以节省资源开销，也能满足终端设备的传输需求。
可选地，第一数据量与第一数据的数据量对应。也就是说，第一数据量可以是第一数据的数据量，或者是第一数据量比第一数据的数据量可以大一些，这样，传输第一数据量的数据的资源也能传输第一数据。换句话说，第一数据量可以不限定为是第一数据的数据量，可以是与第一数据的数据量类似的多个数据的数据量的平均值或者最大值等。
可选地，第二数据量与第二数据的数据量对应。也就是说，第二数据量可以是第二数据的数据量，或者是第二数据量比第二数据的数据量可以大一些，这样，传输第二数据量的数据的资源也能传输第二数据。换句话说，第二数据量不限定为是第二数据的数据量，可以是与第二数据的数据量类似的多个数据的数据量的平均值或者最大值等。
在一些可能的实现方式中，向网络设备指示终端设备期望改变传输数据的资源大小，包括：向网络设备发送第一指示信息，第一指示信息用于指示终端设备期望改变传输的数据量或者期望改变传输数据的资源大小。
在一些可能的实现方式中，第一指示信息包括第二资源大小，也就是说，终端设备期 望将资源大小改变为第二资源大小。
在一些可能的实现方式中，第一指示信息包括资源组标识。可选地，资源组标识用于标识改变前的资源组，如标识第一资源所在的资源组；可选地，资源组标识用于标识改变后的资源组，如标识第二资源所在的资源组；可选地，资源组标识用于标识改变前的资源组和改变后的资源组，如标识第一资源所在的资源组和第二资源所在的资源组。举例来说，三个资源组互相关联，资源组标识可以标识终端设备期望改变后的资源所在的资源组。

可以理解的是，图1中的网络设备110也可以替换成终端设备110，也就是说，本申请实施例应用到设备到设备(device to device，D2D)等直联通信的场景。例如，可以应用 在车辆对其他设备(vehicle to everything，V2X)。
下面为了方便描述，将设备的编号省去，例如“终端设备”表示“终端设备120”，“网络设备”表示“网络设备110”。
终端设备在向网络设备发送上行数据的过程中，终端设备需要在相应的资源上发送上行数据。终端设备发送上行数据的资源主要分为两种，第一种是终端设备发送上行数据的资源是基于网络设备动态调度(dynamic scheduling，DG)的资源。第二种是终端设备发送上行数据的资源是基于网络设备配置授权(configured grant，CG)的资源。
针对第一种基于网络设备动态调度的资源，网络设备动态调度的资源也称为网络设备实时调度的资源，终端设备先要向网络设备发送调度请求(scheduling request，SR)，网络设备基于SR可以向终端设备分配发送缓存状态报告(buffer status reporting，BSR)的资源，终端设备在分配的发送BSR的资源上向网络设备发送BSR，BSR携带终端设备待传输的上行数据的数据量，网络设备根据BSR携带的数据量为终端设备分配传输资源，终端设备在分配的传输资源上传输上行数据，这样，会导致上行数据的传输时延较大。
针对第二种基于网络设备配置授权的资源，网络设备可以预先为终端设备配置资源，终端设备可以在预先配置的资源上传输数据，这样，可以节省传输上行数据的传输时延。但是如果网络设备为终端设备预先配置的资源比较小，终端设备需要传输的上行数据的数据量较大的情况下，会导致部分上行数据无法用配置的资源传输，这些部分上行数据需要利用第一种网络设备动态调度的资源传输，这样会导致部分数据的传输时延较大。如果网络设备为终端设备预先配置的资源比较大，终端设备需要传输的上行数据的数据量较小的情况下，会导致资源浪费的情况。因此，降低时延同时如何节省资源开销是亟待解决的问题。
举例来说，扩展现实(ectended reality，XR)应用包括增强现实(augmented reality，AR)、混合现实(mixed reality，MR)和虚拟现实(vrtual reality，VR)等形式。在AR业务中，终端设备的摄像头需要实时捕捉画面，并将捕捉到的画面进行编码之后作为上行数据发送给网络设备，网络设备再发送给服务器，服务器对上行数据进行渲染处理之后发送给网络设备，网络设备再把渲染处理之后的数据发送给终端设备，用户可以在终端设备上看到AR画面。为了保证用户看到AR画面的连续性，终端设备的摄像头需要每间隔1/60s或16.67ms捕捉一次画面，并按照特定的编码算法对画面进行编码和压缩，通过不同的编码算法得到的编码后的数据包呈现不同的特征。例如，编码后的数据包可能为1个I帧包+7个P帧包；又例如，编码后的数据包为1个I帧包+9个P帧包；再例如，编码后的数据包中为P帧包可以根据画面情况实时变成I帧。其中，I帧包指是编码出的数据包以本帧画面为参考，P帧包指的是编码出的数据包以前一帧画面为参考，表征的是本帧画面与前一帧画面的差值。I帧包的大小与画面的复杂度相关，画面越复杂，I帧包越大，画面越简单，I帧包越小。P帧数据包的大小与画面的变化相关，画面变化大，P帧包越大，画面变化越小，P帧包越小。示例性地，如图2所示，示出了I帧包和P帧包，如果摄像头捕捉画面中，画面的变化较大则P帧包就较大。如果网络设备终端设备配置的一套资源，该套资源的周期为16.67ms，且该套资源中每个资源都比较大，该套资源能够满足画面的变化较大时的P帧包的传输需求，但是如果采用该套资源传输画面变化较小的P帧包，会导致资源比较浪费，即网络设备配置了为终端设备配置了该套资源，该套资源就不会被其他的 终端设备使用，从而会导致资源的浪费。如果网络设备配置的一套资源较小，则该套资源能够满足画面变化较小时的P帧包的传输需求，但是如果采用该套资源传输画面变化较大的P帧包，会导致该套资源无法满足画面变化较大的P帧包的传输需求，例如，摄像头捕捉用户的画面，如果用户持续运动了1s(也就是说画面持续变化了1s)，则终端设备的摄像头就会捕捉约60帧画面，则该60帧中的54帧的P帧包无法采用该套资源传输，甚至6帧的I帧包也无法采用该套资源传输(编码方式为1个I帧包+9个P帧包)，或者只能采用该套资源传输部分数据，剩下的数据需要采用上述第一种动态调度的资源的方式传输，这样会导致剩下的数据传输时延较大。需要说明的是，上述I帧包为根据I帧生成的数据，P帧包为根据P帧生成的数据，具体的，根据I帧或者P帧生成的数据可以分成一个或多个互联网协议(internet protocol，IP)包，即I帧包和P帧包可能实际与一个或多个IP包对应。
需要说明的是，本申请实施例提到的资源可以为上行资源，例如，本申请实施例中的第一资源和第二资源可以为上行资源。
为了解决上述技术问题，本申请实施例提供的传输上行数据的方法，终端设备可以在配置的第一资源上向网络设备发送第一数据，且终端设备可以向网络设备指示终端设备需要改变传输数据的资源大小，终端设备可以基于向网络设备指示的终端设备需要改变传输数据的资源大小，终端设备在不同于第一资源的资源大小的配置的第二资源上传输不同于第一数据的数据大小的第二数据，也就是说，针对不同大小的数据，终端设备可以在不同的资源大小的配置资源上传输。能够满足数据的传输需求，避免采用实时调度资源的方式，有利于降低传输时延。
下面结合图3描述本申请实施例提供的传输上行数据的方法300。方法300包括：
S301，网络设备向终端设备发送第三无线资源控制(radio resource control，RRC)消息，终端设备从网络设备接收第三RRC消息，第三RRC消息用于配置第一资源大小的资源。
具体地，第三RRC消息可以配置第五资源组。第五资源组包括一个或多个资源。第五资源组中的每个资源的资源大小为第一资源大小。可选地，第三RRC消息配置的第五资源组中的资源为周期性资源。
可选地，第三RRC消息具体用于指示第五资源组中的每个资源的时频位置。若第三RRC消息配置的第五资源组中的资源为周期性资源，则第三RRC消息可以指示第五资源组中的资源的资源周期。可选地，第三RRC消息具体用于指示第五资源组中的每个资源的时频位置，包括：第三RRC消息用于指示第五资源组中的每个资源的起始位置和第一资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。
可选地，第三RRC消息可以配置至少一个资源组，至少一个资源组中每个资源组包括至少一个资源，同一资源组中的每个资源的资源大小相同，不同资源组中的每个资源的资源大小可以不相同也可以相同。其中，至少一个资源组包括第五资源组。可选地，第三RRC消息可以配置至少一个资源组中各个资源组的资源周期，以及配置各个资源组中包括的各个资源的时频位置。可选地，第三RRC消息用于配置各个资源组包括的每个资源的时频位置，具体包括：第三RRC消息配置各个资源组包括的每个资源的起始位置和资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。不同资源组 对应的资源周期可以相同或者不同。可选地，若第三RRC消息配置了至少一个资源组，则第三RRC消息还可以指示至少一个资源组中每个资源组的索引。
可选地，在S301中，网络设备可以根据终端设备的业务类型为不同的业务类型配置不同的资源。例如，终端设备在S301中的第三RRC消息为终端设备的第一业务配置第一资源大小的资源。下面S302和S306中分别传输的第一数据和第二数据为第一业务对应的数据。例如，第一业务为AR业务。
示例性地，对于配置的授权类型1(configured grant Type 1)，S301中的第三RRC消息用于配置第五资源组，且配置的第五资源组中的资源即刻就可以生效，终端设备可以利用配置第五资源组中的资源传输S302中的第一数据。
需要说明的是，方法300中，S301中可以只配置一次，可以利用一次配置传输多次数据。换句话说，每次传输数据的过程中，S301不是必选步骤，是可选步骤。
S302，终端设备在配置的第一资源上向网络设备发送第一数据，网络设备在配置的第一资源上从终端设备接收第一数据。
其中，配置的第一资源可以为S301中第三RRC消息配置的第五资源组中的资源。
可选地，第一资源的第一资源大小能够使得终端设备传输第一数据。换句话说，终端设备可以在S301配置的资源上选择的第一资源的第一资源大小能够满足传输第一数据的需求。可选地，如果第一资源的第一资源大小不能满足传输第一数据的需求，则终端设备可以采用在第一资源上传输第一数据的部分数据，剩余部分数据可以采用实时调度资源的方式传输。
示例性地，结合图2所示的AR场景下，第一数据可以是P帧对应的数据包。
S303，终端设备确定在未来的第一时间段内期望传输的第二数据量与第一数据的第一数据量的差值的绝对值大于预设值。
可选地，在S303之前，终端设备可以确定未来的第一时间段内每个资源上期望传输的第二数据量。可选地，终端设备可以根据当前的数据量变化确定未来第一时间段内每个资源上期望传输的第二数据量。例如，终端设备确定在S302传输的第一数据的数据量为第一数据量，如果终端设备确定即将传输的数据的数据量相对于第一数据量增加较多或者减少较多，且即将传输的数据的数据量基本都接近第二数据量，因此，终端设备可以确定未来的第一时间段内每个资源上期望传输的数据量为第二数据量。
也就是说，终端设备确定在未来的第一时间段内每个资源上期望传输的第二数据量较大，如果继续采用与第一资源大小一致的资源传输第二数据，则会导致不满足未来数据的传输需求。或者终端设备确定在未来的第一时间段内期望传输的第二数据量较少，如果继续采用与第一资源大小一致的资源传输第二数据，则会导致浪费资源。因此，终端设备确定期望改变传输数据的资源大小。
可选地，预设值可以为协议规定的或者是网络设备配置给终端设备的或者是终端设备自身确定的。
可选地，第一时间段可以是已知的值也可以是未知的值。例如终端设备如果可以获知第二数据量的数据需要持续的时间，此时可以理解为第一时间段为已知的值。如果终端设备无法获知第二数据量的数据需要持续的时间，此时可以理解为第一时间段为未知的值，也就是说，第二数据量的数据持续的时间结束的时刻为第一时间段的结束时刻，如果终端 设备能够获知第二数据量的数据持续的时间，则第一时间段已知，如果终端设备无法获知第二数据量的数据持续的时间，则第一时间段未知。
可选地，第一时间段可以是具体的一段时间，例如为后续一帧的时间或N(N为大于1的整数)帧的时间、或后续M个时隙的时间或M秒的时间(M为大于0的数)；也可以为未来无限长的时间，也就是说第一时间段为未来的时间段或者是以后的时间段或者是后续的时间段。
可选地，第二数据量可以是未来的第一时间段内每个资源上需要传输数据的数据量的最大值，或者是平均值。
示例性地，结合图2所述的AR场景下，第一数据可以是一个P帧包，如果终端设备确定P帧包的大小发生变化，例如，第一数据是静止场景下的P帧包，此时传输第一数据的第一资源较小，终端设备的摄像头捕捉到画面开始运动，此时P帧包变大，则终端设备确定在未来的第一时间段内需要传输的P帧包的数据量较大，如果继续采用开始的P帧包的第一资源大小的资源传输未来第一时间段内的P帧包，则会导致资源无法满足未来第一时间段内的数据传输需求，因此，终端设备确定期望改变传输数据的资源大小。其中，未来第一时间段可以理解为画面运动的时间。又例如，第一数据是运动场景下的P帧包，此时传输第一数据的第一资源较大，终端设备的摄像头捕捉到画面基本静止，也就是说P帧包变小，则终端设备确定在未来的第一时间段内需要传输的P帧包的数据量较小，如果继续采用开始的P帧包的第一资源大小的资源传输未来第一时间段内的P帧包，则会导致资源浪费。因此，终端设备确定期望改变传输数据的资源大小。其中，未来第一时间段可以为画面静止的时间。
可选地，S303，触发S304。
可以理解的是，还可以是其他的触发条件触发终端设备执行S304，不限于是S303触发终端设备执行S304。例如，终端设备确定第一数据的传输时延较大时，可以触发终端设备执行S304。又例如，终端设备确定第一资源大小小于与第一资源关联的数据逻辑信道对应的数据所需的资源大小时，可以触发终端设备执行S304。再例如，终端设备在未来第一时间段内期望改变传输的数据量或者改变传输数据的资源大小，可以触发终端设备执行S304。
S304，终端设备向网络设备发送第一指示信息，网络设备接收终端设备发送的第一指示信息，第一指示信息用于指示终端设备在未来第一时间段内期望传输的第二数据量或者期望的第二资源大小。
可选地，终端设备还可以通过向网络设备发送第一资源大小与第二资源大小的差值来指示终端设备期望传输第二数据量对应的第二资源大小，也就是说，第一指示信息可以指示第一资源大小和第二资源大小的差值，通过差值间接指示终端设备未来第一时间段内期望传输的第二资源大小，网络设备接收到第一指示信息之后根据差值以及第一资源大小确定终端设备期望的第二资源大小。可选地，终端设备还可以通过向网络设备发送第一数据的第一数据量与第二数据的数据量的差值来指示终端设备期望传输第二数据量，也就是说，第一指示信息可以指示第一数据量和第二数据量的差值，通过差值间接指示终端设备未来第一时间段内期望传输的第二数据量，终端设备接收到第一指示信息之后根据差值以及资源数据量确定终端设备期望传输的第二数据量。
可选地，若第一时间段是具体的一段时间，则第一指示信息用于指示终端设备在未来第一时间段内期望传输的第二数据量或者期望的第二资源大小，而当第一时间段结束后，默认恢复到原来传输的数据量或原来的资源大小，例如为第一数据量或第一资源大小。
可选地，若第三RRC消息指示至少一个资源组中每个资源组的索引，则方法300还可以包括：终端设备向网络设备指示第一资源所在的资源组的索引，即终端设备向网络设备指示第五资源组的索引。可选地，终端设备可以通过第一指示信息向网络设备指示第五资源组的索引，也可以通过不同于第一指示信息的其他指示信息向网络设备指示第五资源组的索引。网络设备可以通过第五资源组的索引确定终端设备需要改变网络设备配置的第五资源组的资源大小。
在S304中，终端设备通过一下任意一种方式可以向网络设备发送第一指示信息：
方式一，终端设备向网络设备发送携带BSR的介质接入控制(medium access control，MAC)控制单元(control element，CE)，第一指示信息可以为携带BSR的MAC CE。即可以将携带BSR的MAC CE理解为用于指示终端设备期望在未来第一时间段内传输的第二数据量或者第二资源大小。或者可以将携带BSR的MAC CE理解为终端设备期望在未来第一时间段内的资源的大小改变为第二资源大小。或者将携带BSR的MAC CE理解为终端设备需要在未来第一时间段内的待传输的数据量改变为第二数据量。
可选地，在方式一中，在S304之前，网络设备进行特定的配置：特定的业务类型(如AR业务的上行数据)可以承载在一个或多个特定的逻辑信道上，该一个或多个特定的逻辑信道属于一个或多个特定的逻辑信道组，该一个或多个特定的逻辑信道组与一个或多个特定的配置的资源组关联。例如，网络设备可以在S301中的第三RRC消息中进行该特定的配置。终端设备可以上报的特定的逻辑信道组的BSR MAC CE，网络设备可以理解为：终端设备上报的特定的逻辑信道组的缓存大小(buffer size)用于指示终端设备在未来第一时间段内期望传输该特定的逻辑信道组对应的第二数据量或者第二资源大小。这样，基于网络设备进行特定的配置终端设备上报特定的逻辑信道组的BSR MAC CE，网络设备可以将携带BSR的MAC CE理解为该特定的逻辑信道组上未来的第一时间段内期望传输的第二数据量或者期望的第二资源大小。
可选地，在方式一中，在终端设备向网络设备发送携带BSR的MAC CE之前，网络设备可以向终端设备指示携带BSR的MAC CE的物理意义为：指示终端设备在未来第一时间段内期望传输的数据量或者期望传输的数据量对应的资源大小，即网络设备向终端设备指示携带BSR的MAC CE的物理意义的目的是为了避免终端设备发送BSR的MAC CE是为了上报当前待传输的数据量，当终端设备需要上报在未来第一时间段内期望传输的数据量或者期望传输的数据量对应的资源大小时，可以直接复用携带BSR的MAC CE，携带BSR的MAC CE可以携带终端设备在未来第一时间段内期望传输第二数据量或者第二资源大小。
其中，携带BSR的MAC CE可以为短的缓存状态报告(short BSR)MAC CE、或者短截断的缓存状态报告(short truncated BSR)MAC CE、或者长的缓存状态报告(long BSR)MAC CE、或者长截断的缓存状态报告(long truncated BSR)MAC CE。其中，short BSR MAC CE和short truncated BSR MAC CE为一个字节的长度，其中该一个字节包括3比特域用于指示逻辑信道组标识，以及5比特域用于指示缓存大小(buffer size)的值。也就是说，在 本申请实施例中，该5比特于用于指示终端设备期望未来传输的数据量或者期望的资源大小，如某个逻辑信道组对应的比特域用于指示终端设备期望未来传输的第二数据量或者期望的第二资源大小。long BSR MAC CE和short long BSR MAC CE为一个或多个字节的长度，其中包括1个字节(8比特)域对应8个逻辑信道组，其中每一比特用于指示对应的逻辑信道组是否上报了缓存大小，以及还包括一个或多个1个字节(8比特)域用于指示缓存大小，其中有多少个逻辑信道组指示了上报了缓存大小，则有多少个1个字节(8比特)域指示对应的缓存大小的值。也就是说，在本申请实施例中，一个或多个1个字节(8比特)域分别用于指示8个逻辑信道组未来期望传输的据量或者期望的资源大小，如某个逻辑信道组对应的比特域用于指示终端设备期望未来传输的第二数据量或者期望的第二资源大小。
上述方式一中，终端设备可以直接复用携带BSR的MAC CE，通过携带BSR的MAC CE指示终端设备在未来第一时间段内期望传输第二数据量或者第二资源大小，换句话说，携带BSR的MAC CE对应的逻辑信道标识(logical channel identity，LCID)与指示终端设备在未来第一时间段内期望传输第二数据量或者第二资源大小的MAC CE的LCID相同，这样，可以简化设计，降低通信协议的复杂度。如表1所示，携带BSR的MAC CE对应的LCID为索引62，则索引62也可以指示终端设备上报在未来第一时间段内期望传输的数据量或者期望传输的数据量对应的资源大小，终端设备表1中的PHR为功率余量报告(power headroom report)的简称，CCCH为公共控制信道(common control channel)的简称。

Figure PCTCN2022083693-appb-000002
方式二，终端设备向网络设备发送MAC CE，MAC CE可以携带第一指示信息。可选地，携带第一指示信息MAC CE的格式与携带BSR的MAC CE的格式类似。本申请中携带第一指示信息的MAC CE的表示终端设备未来第一时间段内期望的第二数据量或者第二数据量对应的第二资源大小。其中，携带第一指示信息的MAC CE与携带BSR的MAC CE的LCID可以不同。例如，在表1中携带第一指示信息的MAC CE的LCID的索引可以为33–51中的一个，如可以为34。
可选地，若终端设备向网络设备指示所述第一资源所在的资源组的索引，即终端设备向网络设备指示第五资源组的索引。若终端设备可以通过第一指示信息向网络设备指示第五资源组的索引，则方式二中的MAC CE可以携带第一指示信息，第一指示信息指示终端设备未来第一时间段内期望的第二数据量或者第二资源大小，以及指示第五资源组的索引，即此时第一指示信息指示将网络设备预先配置的第五资源组中的资源进行改变，改变后的资源大小为第二资源大小。若终端设备通过不同于第一指示信息的其他指示信息向网络设备指示资源组的索引，则方式二中的MAC CE可以携带第一指示信息和指示资源组索引的指示信息，或者方式二中的MAC CE携带可以第一指示信息，其他的MAC CE可以携带指示资源组索引的指示信息。
S305，网络设备向终端设备发送第一RRC消息，第一RRC消息用于配置第二资源大小的资源。
具体地，第一RRC消息可以配置第一资源组，第一资源组包括一个或多个资源，第一资源组中每个资源的资源的大小为第二资源大小，其中，若第一指示信息指示第二资源大小，则网络设备根据第一指示信息确定第二资源大小，若第一指示信息指示第二数据量，则网络设备根据第二数据量确定第二资源大小。可选地，第一RRC消息配置的该组资源为周期性资源。
可选地，第一RRC消息具体用于指示第一资源组中的每个资源的时频位置。若第一RRC消息配置的第一资源组中的资源为周期性资源，则第一RRC消息可以指示第一资源组中的资源的资源周期。可选地，第一RRC消息具体用于指示第一资源组中的每个资源的时频位置，包括：第一RRC消息用于指示第一资源组中的每个资源的起始位置和第一资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。
示例性地，对于配置的授权类型1(configured grant Type 1)，S305中的第一RRC消息用于配置第一资源组，且配置的第一资源组中的资源即刻就可以生效，终端设备可以利用配置的第一资源组中的资源传输S306中的第二数据。
需要说明的是，方法300中，S305中可以只配置一次，可以利用一次配置传输多次数据。换句话说，每次传输数据的过程中，S305不是必选步骤，是可选步骤。
可选地，第三RRC消息和第一RRC消息配置的两组资源的周期可以相同。示例性地，对于AR业务，第三RRC消息可以配置一组资源的周期可以是16.67ms，第一RRC消息可以配置一组资源的周期也可以是16.67ms。
可选地，方法300也可以不存在S305，网络设备接收到第一指示信息之后，确定终端设备不能将资源大小改变为第二资源大小，也就是说网络设备可以不响应第一指示信息，网络设备就可以不向终端设备发送第一RRC消息，这样，终端设备就无法获得第二资源大小的资源，因此，也无法执行S306，终端设备可以继续在第五资源组包括的第一资源大小的资源上传输第二数据。
S306，终端设备配置的第二资源上向网络设备发送第二数据，网络设备在配置的第二资源上从终端设备接收第二数据。
其中，配置的第二资源可以为S304中第一RRC消息配置的第一资源组中的资源，也即第二资源的资源大小为第二资源大小。
示例性地，结合图2所示的AR场景下，第二数据可以是P帧对应的数据包，若第一数据和第二数据都是P帧对应的数据包，则第一数据对应的P帧与第二数据对应的P帧的数据量差别较大，例如第一数据对应的P帧与第二数据的P帧的数据量的差值的绝对值大于预设值。
需要说明的是，方法300中各个步骤可以是可选步骤，且各个步骤的执行顺序可以根据内在逻辑确定。例如，方法300中的S301、S303、S305或者S306为可选步骤。
上述方法300中，终端设备在配置的第一资源上传输第一数据，当终端设备确定未来第一时间段内数据量变化较大，如变为第二数据量，则终端设备可以向网络设备发送第一指示信息来指示第二数据量或者第二数据量对应的第二资源大小，网络设备通过第一RRC消息配置第二资源，在配置的第二资源上传输第二数据能满足传输需求，也能降低时延。且网络设备可以将S301中第三RRC消息配置的终端设备还未使用的其他的资源分配给其他的终端设备使用，从而有利于节省资源开销。
配置的授权类型1场景下网络设备可以通过S301中的第三RRC消息配置第五资源组，通过S305中的第一RRC消息配置第一资源组。下面结合方法400描述在配置的授权类型2场景下传输上行数据的方法400。如图4所示，方法400包括：
S401，网络设备向终端设备发送第三RRC消息，终端设备从网络设备接收第三RRC消息，第三RRC消息用于配置第五资源组。
其中，第三RRC消息配置的第五资源组为第五资源组的资源参数，例如第五资源组的资源参数包括第五资源组的第一资源周期、授权无线网络临时标识(configured scheduling-radio network temporary identifier，CS-RNTI)、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程个数中的一个或多个。但是第三RRC消息可以不配置第五资源组中的资源的资源位置。
可选地，第三RRC消息用于配置一个或者多个资源组的资源参数，一个或多个资源组包括第五资源组。示例性地，第三RRC消息可以配置指示各个资源组的索引。
可选地，网络设备在满足触发条件下，执行S402。例如，触发条件为终端设备与网络设备建立的非接入层(non-access stratum，NAS)连接，或者触发条件为终端设备与网络设备建立了协议数据单元(protocol data unit，PDU)会话连接，或者触发条件为网络设备向终端设备发送了PDU会话的参数，如服务质量(quality of service，QoS)的参数等。需要说明的是，触发条件不限于上述条件，可以由网络设备实现，本申请实施例并不限定。
S402，网络设备向终端设备发送第二下行控制信息(downlink control information，DCI)，第二DCI用于激活第五资源组，并且第二DCI用于指示第五资源组中每个资源的资源位置。
其中，第二DCI指示的第五资源组包括一个或多个资源，第五资源组中每个资源大小为第一资源大小。
也就是说，在S401中，第三RRC消息可以预先配置第五资源组的资源参数，但是可以不配置第五资源组中的资源的资源位置。S402中的第二DCI可以激活第五资源组且指示第五资源组中的资源位置，此时，第三RRC消息配置的第五资源组的资源参数生效，并且终端设备也可以获知第五资源组中的资源的资源位置。
可选地，第二DCI用于指示第五资源组中每个资源的资源位置，包括：第二DCI用于指示第五资源组中的每个资源的起始位置和第一资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。
可选地，如果S401中第三RRC消息配置了多个资源组，则第二DCI可以携带资源组的索引，即第二DCI需要具体激活哪个资源组，并指示或者配置该资源组中的资源的资源位置。
可选地，S402中的第二DCI可以通过授权无线网络临时标识(configured scheduling-radio network temporary identifier，CS-RNTI)加扰。
S403，终端设备在第一资源上向网络设备发送第一数据，网络设备在第一资源上从终端设备接收第一数据。
其中，第一资源为S402中第二DCI激活的第五资源组中的资源。
可选地，第一资源的第一资源大小能够使得终端设备传输第一数据。换句话说，终端设备可以在S402所激活的资源上选择的第一资源大小的第一资源能够满足传输第一数据的需求。可选地，如果第一资源的第一资源大小不能满足传输第一数据的需求，则终端设备可以采用在第一资源上传输第一数据的部分数据，剩余部分数据可以采用实时调度资源的方式传输。
示例性地，结合图2所示的AR场景下，第一数据可以是P帧对应的数据包。
S404，终端设备确定在未来的第一时间段内期望传输的第二数据量与第一数据的第一数据量的差值的绝对值大于预设值。
其中，S404的相关描述参见S303的描述。
可选地，S404，触发S405。
可以理解的是，还可以是其他的触发条件触发终端设备执行S405，不限于是S404触发终端设备执行S405。例如，终端设备确定第一数据的传输时延较大时，可以触发终端设备执行S405。又例如，终端设备确定第一资源大小小于与第一资源关联的数据逻辑信道对应的数据所需的资源大小时，可以触发终端设备执行S405。再例如，终端设备在未来第一时间段内期望改变传输的数据量或者改变传输数据的资源大小，可以触发终端设备执行S304。
S405，终端设备向网络设备发送第一指示信息，网络设备接收终端设备发送的第一指示信息，第一指示信息用于指示终端设备在未来第一时间段内期望传输的第二数据量或者期望的第二资源大小。
可选地，第一指示信息可以指示终端设备期望传输的第二数据量或者期望的第二资源大小，或者第一指示信息可以间接指示终端设备期望传输的第二数据量或者期望的第二资源大小。
可选地，终端设备还可以通过向网络设备发送第一资源大小与第二资源大小的差值来指示终端设备期望传输第二数据量对应的第二资源大小，也就是说，第一指示信息可以指示第一资源大小和第二资源大小的差值，通过差值间接指示终端设备未来第一时间段内期望传输的第二资源大小，网络设备接收到第一指示信息之后根据差值以及第一资源大小确定终端设备期望的第二资源大小。可选地，终端设备还可以通过向网络设备发送第一数据的第一数据量与第二数据的数据量的差值来指示终端设备期望传输第二数据量，也就是说，第一指示信息可以指示第一数据量和第二数据量的差值，通过差值间接指示终端设备未来第一时间段内期望传输的第二数据量，终端设备接收到第一指示信息之后根据差值以及资源数据量确定终端设备期望传输的第二数据量。
可选地，若S401中第三RRC消息配置了多个资源组的资源参数，则方法400还可以包括：终端设备向网络设备指示第一资源所在的资源组的索引，即终端设备向网络设备指示第五资源组的索引。可选地，终端设备可以通过第一指示信息向网络设备指示第五资源组的索引，也可以通过不同于第一指示信息的其他指示信息向网络设备指示资源组的索引。网络设备可以通过第五资源组的索引确定终端设备需要改变网络设备配置的第五资源组的资源大小。
终端设备向网络设备发送第一指示信息的方式可以参见S304中的方式一和方式二。
其中，S405触发S406。
S406，网络设备向终端设备发送第一DCI，第一DCI用于激活第五资源组，并且第一DCI用于指示第五资源组中每个资源的资源位置。
其中，第一DCI指示的第五资源组包括一个或多个资源，一个或多个资源可以组成一个第五资源组，第五资源组中每个资源大小为第二资源大小，此时第五资源组也可以称为第一资源组。
也就是说，S401配置了第五资源组的资源参数，S402中的第二DCI激活第五资源组，第五资源组的资源参数生效，并且第二DCI指示的第五资源组中每个资源的资源大小为第一资源大小。S406中的第一DCI激活第五资源组，第五资源组的资源参数生成，并且第 一DCI指示的第五资源组中每个资源的资源大小为第二资源大小，此时第五资源组可以称为第一资源组。换句话说，第二DCI和第一DCI所要激活的第五资源组的资源参数可以在S401中的第三RRC消息中配置，第二DCI和第一DCI指示的该资源参数对应的资源大小不同。
可选地，若S401中的第三RRC消息配置了多个组的资源参数，包括第五资源组的资源参数和第一资源组的资源参数。S402中的第二DCI可以用于激活S401配置的第五资源组，并且第二DCI用于指示第五资源组中的资源的资源位置，第五资源组中的资源的资源大小为第一资源大小。在S406中，网络设备向终端设备发送的第一DCI用于激活S401配置的第一资源组的资源参数，并且第一DCI用于指示第一资源组中的资源的资源位置，第一资源组中的资源的资源大小为第二资源大小。当然S406中，网络设备向终端设备发送的第一DCI也可以用于激活S401配置的第五资源组，并且第一DCI用于指示第五资源组中的资源，第五资源组中的资源的资源大小为第二资源大小，此时的第五资源组称为第一资源组。也就是说，S402中的第二DCI与S406中的第一DCI可以激活同一个资源组，此时，S402中的第五资源组中的资源与S406中的第五资源组中的资源的资源大小不同，S402中的第五资源组包括的资源的资源大小为第一资源大小，S406中的第五资源组包括的资源的资源大小为第二资源大小。S402中的第二DCI与S406中的第一DCI也可以激活不同资源组的资源参数，且两个DCI指示的资源的资源大小不同，第二DCI指示的是第一资源大小的资源，第一DCI指示的是第二资源大小的资源。
可选地，S406中的第一DCI可以通过CS-RNTI加扰。
可选地，方法400也可以不存在S406，网络设备接收到第一指示信息之后，确定终端设备不能将资源大小改变为第二资源大小，也就是说网络设备可以不响应第一指示信息，网络设备就可以不向终端设备发送第一DCI，这样，终端设备就无法获得第二资源大小的资源，因此，也无法执行S407，终端设备可以继续在第一资源大小的资源上传输第二数据。
S407，终端设备在第二资源上向网络设备发送第二数据，网络设备在第二资源上从终端设备接收第二数据。
其中，第二资源的大小为第二资源大小。第二资源为S406中第一DCI指示的资源组中的一个资源。
示例性地，结合图2所示的AR场景下，第二数据可以是P帧对应的数据包，若第一数据和第二数据都是P帧对应的数据包，则第一数据对应的P帧与第二数据对应的P帧的数据量差别较大，例如第一数据对应的P帧与第二数据的P帧的数据量的差值的绝对值大于预设值。
需要说明的是，方法400中各个步骤可以是可选步骤，且各个步骤的执行顺序可以根据内在逻辑确定。例如，方法400中的S404、S406或者S407为可选步骤。
为了更好的说明上述方法300和方法400，下面结合图2所示的AR业务的特征，举例描述，如图5所示，在方法300的配置的授权类型1场景下，网络设备可以在S301中配置资源周期为资源周期为16.67ms的第一套CG资源，其中第一套CG资源用于传输P帧包，第一套CG资源的资源大小为第一资源大小，如为P_low。当然，网络设备还可以在S301中配置资源周期为16.67*8ms的第二套CG资源，第二套CG资源用于传输I帧包。AR的业务变化如图2所示，当终端设备在第一套CG资源上传输了3个P帧包的后，如 图5所示从第四个P帧包起，P帧包的数据量变大，如果终端设备继续用第一套CG资源传输P帧包则会导致第一套CG资源不够传输P帧包的数据，部分数据可能需要实时调度的方式传输，则会导致传输时延较大。因此，终端设备在传输第四个P帧包时发现第一套CG资源不足，因此，终端设备预测可能由于画面变化较大导致P帧包较大，画面变化至少会持续一定的时间，例如画面变化了1秒，则至少有50多帧的P帧包无法采用第一套CG资源传输，即终端设备向网络设备发送第一指示信息，第一指示信息可以指示未来期望传输的P帧包的第二数据量或者P帧包对应的第二资源大小，第二资源大小大于第一资源大小，例如第二数据量为第四个P帧包的数据量或者第二资源大小为第四个P帧包对应的资源大小或者比第四个P帧包对应的资源大小再大一些，即第二资源大小为终端设备确定的画面变化较大时需要的最大资源，如第二资源大小为P_high。网络设备接收到第一指示信息之后，向终端设备发送的第一RRC消息，第一RRC消息用于配置第三套CG资源，第三套CG资源的资源大小为第二资源大小，终端设备可以在第三套CG资源上继续传输P帧包，例如第五个P帧包可以在第三套CG资源上传，这样，第三套CG资源可以满足传输P帧包的需求，且第一套CG资源剩余的资源可以用于其他终端设备传输数据，能够节省资源开销。需要说明的是，这个例子中，第四个P帧包可以采用第一套CG资源传输，第一套CG资源传输不满足时，可以采用动态调度的方式将第四个P帧包发送给网络设备，从第五个P帧包开始可以使用第三套CG资源。也需要说明的是，如果同一个资源位置有两个资源，例如，I帧包可能有第二套CG资源中的资源也有第一套CG资源(或者第三套CG资源)中的资源，则由于I帧包的优先级高于P帧包的优先级，因此，I帧包优先采用第二套CG资源中的资源传输。在这个例子中，第一资源为第一套CG资源中的资源，第一数据为前三个P帧包中的任意一个P帧包，第二资源为第三套CG资源中的资源，第二数据为后三个P帧包中的任意一个P帧包。如果终端设备捕捉的画面的是先变化大，之后变化小，则第一资源大小大于第二资源大小。与方法300类似，在方法400中，S401中第三RRC消息可以配置一套CG资源的资源参数，S402中的第二DCI用于激活该套CG资源，并指示第一资源大小的资源的资源位置，此时称为第一套CG资源。S406中的第一DCI用于激活该套CG资源数，并指示第二资源大小的资源，此时称为第三套CG资源，其中，第一套CG资源和第三套CG资源的资源周期相同，都为16.67ms。其中，在方法400中，网络设备还可以通过另一个RRC消息配置第二套CG资源的资源参数，且网络设备还可以通过另一个DCI激活第二套CG资源，并指示第二套CG资源的资源的资源位置。
上述方法300和方法400描述的是，终端设备向网络设备发送的第一指示信息指示的是终端设备在未来第一时间段内期望传输第二数据量或者第二资源大小。下面结合方法600和方法700描述，终端设备向网络设备发送的第一指示信息指示的是终端设期望改变未来第一时间段内传输数据的资源大小。如图6所示，方法600包括：

可选地，若第一确认信息用于指示网络设备没有接收到第一指示信息，则终端设备可以继续执行S605。可选地，若第一确认信息用于指示网络设备没有接收到第一指示信息，则终端设备就无法使用第二资源大小的资源，因此，也无法执行S607，终端设备可以继续在第一资源大小的资源上传输第二数据。
可选地，方法600可以不存在S606步骤，即网络设备可以不向终端设备发送第一确认信息，终端设备在S605中向网络设备发送了第一指示信息之后，即执行S607，也就是说，终端设备默认网络设备收到了第一指示信息。
可选地，方法600可以不存在S606步骤，即网络设备可以不向终端设备发送第一确认信息，若终端设备通过PUSCH向网络设备发送第一指示信息，终端设备在发送PUSCH的配置资源的下一个配置资源到来之前，没有接收到网络设备发送的重传消息，终端设备确定网络设备接收到了第一指示信息。也就是说，终端设备可以将第一指示信息通过PUSCH发送到网络设备，终端设备没有收到网络设备需要重传的消息表示网络设备接收到了PUSCH，也即接收到第一指示信息。

S607，终端设备在第二资源上向网络设备发送第二数据，网络设备在第二资源上从终端设备接收第二数据。
其中，第二资源为S602中的第二RRC消息配置的第二资源大小的资源。也就是说，对于上述第二资源组，第二资源为第二资源组中第二资源大小的资源。
对于上述第三资源组和第四资源组，由于第三资源组与第四资源组关联，S603中终端设备在第三资源组中的第一资源上传输第一数据，终端设备向网络设备发送第一指示信息之后，可以在于第三资源组关联的第四资源组中的第二资源上发送第二数据。也就是说，对于第三资源组和第四资源组，终端设备需要根据第三资源组以及两个资源组的关联关系确定第四资源组，并在第四资源组中的第二资源上发送第二数据。
示例性地，结合图2所示的AR场景下，第二数据可以是P帧对应的数据包，若第一数据和第二数据都是P帧对应的数据包，则第一数据对应的P帧与第二数据对应的P帧的数据量差别较大，例如第一数据对应的P帧与第二数据的P帧的数据量的差值的绝对值大于预设值。
需要说明的是，方法600中各个步骤可以是可选步骤，且各个步骤的执行顺序可以根据内在逻辑确定。例如，方法600中的S601、S604、S605或者S607为可选步骤。
在上述方法600中，网络设备可以通过第二RRC消息配置第一资源大小的资源和第二资源大小的资源，终端设备在第一资源大小的第一资源上传输第一数据，当终端设备确定在未来第一时间段内期望传输的第二数据量与第一数据的第一数据量的差值大于预设值时，终端设备向网络设备指示终端设备在未来第一时间段内期望改变传输数据的资源大小，终端设备可以将传输数据的资源从第一资源大小改变为第二资源大小，能够满足数据的传输需求，也能降低传输时延。且在S605之前，网络设备可以将第二RRC消息配置的第二资源大小的资源可以分配给其他终端设备使用，在S607之后，网络设备可以将第二RRC消息配置的第一资源大小的资源可以分配给其他终端设备使用，从而可以节省资源开销。

需要说明的是，为了简化描述S702中描述的是第四RRC消息配置了第五资源组和第一资源组，第五资源组和第一资源组也可以是不同的RRC消息配置的，例如，第四RRC消息配置第五资源组，另一个RRC消息配置第一资源组。本申请实施例不予限制。
可选地，网络设备可以根据第一资源大小和第二资源大小配置第五资源组和第一资源组也就是说，网络设备配置的第五资源组与第一资源大小对应，配置的第一资源组与第二资源大小对应。
可选地，第五资源组和第一资源组可以相同或者不同。第五资源组和第一资源组相同可以理解为：第五资源组的资源参数与第一资源组的资源参数相同，例如，第五资源组的资源参数包括第一资源周期，第一资源组的资源参数包括第二资源周期，第一资源周期和第二资源周期可以相同，此时，第五资源组的资源参数可以不包括第一资源大小，第一资源组的资源参数可以不包括第二资源大小。第五资源组和第一资源组不同可以理解为：第五资源组的资源参数与第一资源组的资源参数不同，例如，第五资源组的资源参数包括第一资源周期，第一资源组的资源参数包括第二资源周期，第一资源周期和第二资源周期可以不同，和/或，第五资源组的资源参数可以包括第一资源大小，第一资源组的资源参数可以包括第二资源大小，第一资源大小和第二资源大小不同。
可选地，第五资源组与第一资源组相同可以理解为网络设备配置了两个相同的资源组或者网络设备配置了一个资源组。换句话说，第四RRC消息可以配置两个不同的资源组，或者相同的资源组，若第四RRC消息配置了相同的资源组，则可以为两个完全相同的资源组或者为一个资源组。如果第四RRC消息配置了两个资源组，不管这两个资源组是否相同，但是这两个资源组可以关联。如果第四RRC消息配置了一个资源组，则第四RRC消息配置的该资源组不存在关联的资源组，且第四RRC消息配置的该资源组的资源参数不包括资源大小，例如不包括第一资源大小或者第二资源大小。
可选地，网络设备在满足触发条件下，执行S703。例如，触发条件为终端设备与网络设备建立的非接入层(non-access stratum，NAS)连接，或者触发条件为终端设备与网络设备建立了协议数据单元(protocol data unit，PDU)会话连接，或者触发条件为网络设备向终端设备发送了PDU会话的参数，如服务质量(quality of service，QoS)的参数等。需要说明的是，触发条件不限于上述条件，可以由网络设备实现，本申请实施例并不限定。
S703，网络设备向终端设备发送第三DCI，第三DCI用于激活第五资源组，并且第三DCI用于指示第五资源组中每个资源的资源位置。
也就是说，在S702中，第四RRC消息可以预先配置第五资源组的资源参数，但是可以不配置第五资源组中的资源的资源位置。S703中的第三DCI可以激活第五资源组且指示第五资源组中的资源位置，此时，第四RRC消息配置的第五资源组的资源参数生效，并且终端设备也可以获知第五资源组中的资源的资源位置。
可选地，第三DCI用于指示第五资源组中每个资源的资源位置，包括：第三DCI用于指示第五资源组中的每个资源的起始位置和第一资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。
可选地，如果S702中第四RRC消息配置了多个资源组，则第三DCI可以携带资源组的索引，即第三DCI需要具体激活哪个资源组，并配置或指示该资源组中的资源的资源位置。
可选地，S703中的第三DCI可以通过授权无线网络临时标识(configured scheduling-radio network temporary identifier，CS-RNTI)加扰。
S704，终端设备在第一资源上向网络设备发送第一数据，网络设备在第一资源上从终端设备接收第一数据。
其中，第一资源为S703中第三DCI激活的第五资源组中的资源。
可选地，第一资源的第一资源大小能够使得终端设备传输第一数据。换句话说，终端设备可以在S703所激活的资源上选择的第一资源大小的第一资源能够满足传输第一数据的需求。可选地，如果第一资源的第一资源大小不能满足传输第一数据的需求，则终端设备可以采用在第一资源上传输第一数据的部分数据，剩余部分数据可以采用实时调度资源的方式传输。
示例性地，结合图2所示的AR场景下，第一数据可以是P帧对应的数据包。
S705，终端设备确定在未来的第一时间段内期望传输的第二数据量与第一数据的第一数据量的差值的绝对值大于预设值。
其中，S705的相关描述参见S303的描述。
可选地，S705，触发S706。
可以理解的是，还可以是其他的触发条件触发终端设备执行S706，不限于是S705触发终端设备执行S706。例如，终端设备确定第一数据的传输时延较大时，可以触发终端设备执行S706。又例如，终端设备确定第一资源大小小于与第一资源关联的数据逻辑信道对应的数据所需的资源大小时，可以触发终端设备执行S706。再例如，终端设备在未来第一时间段内期望改变传输的数据量或者改变传输数据的资源大小，可以触发终端设备执行S706。
S706，终端设备向网络设备发送第一指示信息，网络设备接收终端设备发送的第一指示信息，第一指示信息用于指示终端设备在未来第一时间段内期望改变传输数据的资源大小。
其中，S706的相关描述参见S605的描述。
S707，网络设备向终端设备发送第一DCI，第一DCI用于激活第一资源组，并且第一DCI用于指示第一资源组中每个资源的资源位置。
其中，第一DCI指示的第一资源组包括一个或多个资源，第一资源组中每个资源大小为第二资源大小。
也就是说，在S702中，第四RRC消息可以预先配置第一资源组的资源参数，但是可以不配置第一资源组中的资源的资源位置。S707中的第一DCI可以激活第一资源组且指示第一资源组中的资源位置，此时，第四RRC消息配置的第一资源组的资源参数生效，并且终端设备也可以获知第一资源组中的资源的资源位置。
可选地，第一DCI用于指示第一资源组中每个资源的资源位置，包括：第一DCI用于指示第一资源组中的每个资源的起始位置和第一资源大小。可选地，每个资源的起始位置可以包括时域起始位置和频域起始位置。
具体地，网络设备在S701中获得第一资源大小和第二资源大小之后，第一资源大小和第二资源大小可以关联，网络设备在S703中的第三DCI指示的第五资源组中的资源，第五资源组包括第一资源大小的资源，因此网络设备在接收到第一指示信息之后，网络设备确定需要激活与第五资源组相关的第一资源组，在网络设备在S707中激活第一资源组并指示第一资源组中的资源，第一资源组包括第二资源大小的资源。
可选地，若S702中的第三RRC消息配置了多个资源组，包括第五资源组和第一资源组。S703中的第三DCI可以用于激活S702配置的第五资源组，并且第三DCI用于指示第五资源组中的资源，第五资源组中的资源的资源大小为第一资源大小。在S707中，网络设备向终端设备发送的第一DCI用于激活S702配置的第一资源组，并且第一DCI用于指示第一资源组中的资源，第一资源组中的资源的资源大小为第二资源大小。如果S702配置的第五资源组和第一资源组相同且只配置了一个资源组，称为第一资源组，S707中，网络设备向终端设备发送的第一DCI也可以用于激活S702配置的第一资源组，并且第一DCI用于指示第一资源组中的资源，第一资源组中的资源的资源大小为第二资源大小。也就是说，S703中的第三DCI与S707中的第一DCI可以激活同一个资源组，此时，S703中第三DCI指示的第一资源组中的资源与S707中第一DCI指示的第一资源组中的资源的资源大小不同，第三DCI指示的第一资源组包括的资源大小为第一资源大小，第一DCI指示的第一资源组的中的资源的资源大小为第二资源大小。S703中的第三DCI与S707中的第一DCI也可以激活不同资源组，此时S701配置的第五资源组与第一资源组不同，但是两个DCI指示的资源的资源大小不同，第三DCI指示的第五资源组的资源大小是第一资源大小，第一DCI指示的第一资源组的资源大小是第二资源大小。
可选地，S707中的第一DCI可以通过CS-RNTI加扰。
可选地，方法700也可以不存在S707，网络设备接收到第一指示信息之后，确定终端设备不能将资源大小改变为第二资源大小，也就是说网络设备可以不响应第一指示信息，网络设备就可以不向终端设备发送第一DCI，这样，终端设备就无法获得第二资源大小的资源，因此，也无法执行S708，终端设备可以继续在第一资源大小的资源上传输第二数据。
S708，终端设备在第二资源上向网络设备发送第二数据，网络设备在第二资源上从终端设备接收第二数据。
其中，第二资源的大小为第二资源大小。第二资源为S707中第一DCI指示的资源组中的一个资源。
示例性地，结合图2所示的AR场景下，第二数据可以是P帧对应的数据包，若第一数据和第二数据都是P帧对应的数据包，则第一数据对应的P帧与第二数据对应的P帧的数据量差别较大，例如第一数据对应的P帧与第二数据的P帧的数据量的差值的绝对值大于预设值。
需要说明的是，方法700中各个步骤可以是可选步骤，且各个步骤的执行顺序可以根据内在逻辑确定。例如，方法700中的S705、S707或者S708为可选步骤。
为了更好的说明上述方法600和方法700，下面结合图2所示的AR业务的特征，举例描述。下面以方法600的配置的授权类型1场景下为例描述。终端设备可以历史经验数据确定P帧包对应的最小的资源的第一资源大小，即为P_low，以及P帧包对应的最大的第二资源大小，记为P_high。或者终端设备可以根据实时数据确定第一资源大小和第二资 源大小。终端设备向网络设备指示P_low和P_high。网络设备向终端设备发送的第二RRC消息用于配置P_low大小且周期为16.67ms的资源以及P_high大小且周期为16.67ms的资源，P_low大小且周期为16.67ms的资源以及P_high大小且周期为16.67ms的资源用于传输P帧包。当然第二RRC消息还可以用于配置I_max大小周期为16.67*8ms的资源，I_high大小周期为16.67*8ms的资源用于传输I帧包。AR的业务变化如图2所示，当终端设备在P_low大小的资源上传输了3个P帧包的后，如图5所示从第四个P帧包起，P帧包的数据量变大，如果终端设备继续用P_low大小的资源传输P帧包则会导致P_low大小的资源不够传输P帧包的数据，部分数据可能需要实时调度的方式传输，则会导致传输时延较大。因此，终端设备在传输第四个P帧包时发现P_low大小的资源不足，因此，终端设备预测可能由于画面变化较大导致P帧包较大，画面变化至少会持续一定的时间，例如画面变化了1秒，则至少有50多帧的P帧包无法采用P_low大小的资源传输，即终端设备向网络设备发送第一指示信息，第一指示信息可以指示未来需要改变P_low大小的资源，P_high大于P_low，例如P_high为第四个P帧包的数据量对应的资源或者比第四个P帧包对应的资源大小再大一些，即P_high为终端设备确定的画面变化较大时需要的最大资源，如第二资源大小为P_high。网络设备接收到第一指示信息之后，向终端设备发送的确认信息，终端设备可以在P_high大小的资源上继续传输P帧包，例如第五个P帧包可以在P_high大小的资源上传，这样，P_high大小的资源可以满足传输P帧包的需求，且P_low大小的资源剩余的资源可以用于其他终端设备传输数据，能够节省资源开销。需要说明的是，这个例子中，第四个P帧包可以采用P_low大小的资源传输，P_low大小的资源传输不满足时，可以采用实时调度的方式将第四个P帧包发送给网络设备，从第五个P帧包开始可以使用P_high大小的资源。也需要说明的是，如果同一个资源位置有两个资源，例如，I帧包可能有I_max大小的资源也有P_low大小的资源(或者P_high大小的资源)，则由于I帧包的优先级高于P帧包的优先级，因此，I帧包优先采用I_max大小的资源中的资源传输。在这个例子中，第一资源为P_low大小的资源，第一数据为前三个P帧包中的任意一个P帧包，第二资源为P_high大小的资源，第二数据为后三个P帧包中的任意一个P帧包。与方法600类似，在方法700中，S702中第四RRC消息可以配置一个资源组的资源周期16.67ms，S703中的第三DCI用于激活资源周期16.67ms，并指示16.67ms对应的资源大小为P_low。S707中的第一DCI用于激活资源周期16.67ms，并指示16.67ms对应的资源大小为P_high。其中，在方法700中，网络设备还可以通过另外的RRC消息配置资源周期16.67*8ms，网络设备还可以通过另外的DCI用于激活资源周期16.67*8ms，并指示周期16.67*8ms对应的资源大小为I_max。
可选地，在与上述方法300、方法400、方法600和方法700不同的另外一个实施例中，终端设备在PUCCH上向网络设备发送SR时，第一时间段为当前时刻至下一个数据之间的时长，也就是说，终端设备向网络设备发送的SR可以指示终端设备在下一个需要改变传输数据的资源大小。如图9所示，网络设备配置了第一套CG资源用于终端设备传输P帧包，配置了第二套CG资源用于终端设备传输I帧包，其中，图9中方框表示资源，填充部分表示数据。当终端设备利用第二套CG资源传输P帧包时，传输到第四个P帧包时，第二套CG资源无法满足第四个P帧包的传输需要，在第一行现有的实时调度方案(即前述的第一种基于网络设备实时调度的资源)中需要执行以下过程：终端设备向网络设备 发送SR，网络设备基于SR向终端设备分配发送BSR的资源，终端设备在分配的BSR的资源是上向网络设备发送BSR，BSR会携带第四个P帧包的数据量，网络设备根据BSR携带的第四个P帧包的数据量为第四个P帧包分配动态授权(dynamic grant，DG)资源，终端设备在网络设备分配的DG资源上传输第四个P帧包，如图9所示，从第四个P帧包到达，到第四个P帧在DG资源上传输，至少有t1的时延，同样地，第五个P帧包也存在t2的时延。当终端设备利用第二套CG资源传输P帧包时，传输到第四个P帧包时，第二套CG资源无法满足第四个P帧包的传输需要，在第二行本申请的方案中，若终端设备能预测从第四个P帧包的数据量会增大，则终端设备可以提前发送SR1，此时的SR1表示下一个P帧包(第四个P帧包)需要改变传输资源，终端设备向网络设备发送SR1，网络设备基于SR1向终端设备分配发送BSR1的资源，终端设备在分配的BSR1的资源是上向网络设备发送BSR1，BSR1携带第四个P帧包的数据量，网络设备根据BSR1携带的第四个P帧包的数据量为第四个P帧包分配DG资源1，终端设备在网络设备分配的DG资源1上传输第四个P帧包，如图9所示，网络设备为可能刚好在第四个P帧包到达时为第四个P帧包分配好了DG资源1，或者在比第四个P帧包到达稍微晚一些分配了DG资源1，这样，相比于第一行的现有的实时调度方案可以节省传输时长。终端设备传输了第四个P帧包之后，确定第五个P帧包的数据量也会增大，终端设备也可以提前发送SR2，此时的SR2表示下一个P帧包(第五个P帧包)需要改变传输资源，终端设备向网络设备发送SR2，网络设备基于SR2向终端设备分配发送BSR2的资源，终端设备在分配的BSR2的资源是上向网络设备发送BSR2，BSR2会携带第五个P帧包的数据量，网络设备根据BSR2携带的第五个P帧包的数据量为第五个P帧包分配DG资源2，终端设备在网络设备分配的DG资源2上传输第五个P帧包，如图9所示，网络设备为可能刚好在第五个P帧包到达时为第五个P帧包分配好了DG资源2，或者在比第五个P帧包到达稍微晚一些分配了DG资源2，这样，相比于第一行的现有的实时调度方案可以节省传输时长。
需要说明的是，为了简化描述，上述实施例中仅以第一资源大小和第二资源大小为例描述，在实际应用中，可以存在三个或者三个以上的资源大小。不同的资源大小上的资源可以传输不同的数据量，为了避免赘述，本申请实施例不予限制。例如，在AR业务中，第一资源大小为画面变化较小时P帧包的最大资源，第二资源大小为画面变化较大的P帧包的最大资源，第三资源大小为I帧包的最大资源。
需要说明的是，资源的大小可以理解为资源在时域的长度和频域的宽度。
需要说明的是，每个资源的资源大小相同可以理解为：每个资源对应的时域资源的长度相同，对应的频域资源的宽度相同。
可以理解的是，上述方法实施例可以是独立的实施例或者是可以互相结合的实施例。不同方法实施例中的步骤可以互相结合称为另外的实施例，同一方法实施例中步骤也可以互相组合成为另外的实施例。
