具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出 于示例目的描述了新空口(NewRadio，NR)系统，并且在以下大部分描述中使用NR术语，这些技术也可应用于NR系统应用以外的应用，如第6代(6 thGeneration，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(evolution Node-B，eNB)、下一代节点B(generation Node-B，gNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Networks，WLAN)接入点、WiFi节点、发送接收点(TransmittingReceivingPoint，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的图像帧的传输方法和设备进行详细地说明。
相关技术中的DRX配置不能适应图像帧的数据量变化，容易导致终端功耗增加或图像帧传输超时。例如，针对XR业务中的I帧(Intra-coded picture)，P帧(Predicted picture)和B帧(Bidirectional predicted picture)，I帧的数据量最大，P帧的数据量居中，而B帧的数据量最小。如果激活窗长度(或称激活窗时长)匹配I帧所需的传输时长，则相对于P帧和B帧所需的传输时长太长，导致终端功率消耗增加；如果激活窗长度匹配P帧所需的传输时长，则相对于I帧所需的传输时长太短，限制基站调度的灵活性；相对于B帧的所需的传输时长仍偏长，导致终端功率消耗增加；如果激活窗长度匹配B帧所需的传输时长，则相对于I帧和P帧所需的传输时长太短，有可能会导致终端来不及传输完一个图像帧就进入休眠状态，造成图像帧传输超时；同时还限制了基站调度的灵活性。
为解决上述技术问题，如图2所示，本申请实施例提供一种图像帧的传输方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端确定与图像帧类型相匹配的非连续接收(Discontinuous Reception，DRX)激活窗长度。
该实施例中提到的图像帧类型可以包括I帧，P帧和B帧等；其中，I帧是一个完整的图像帧，可以不依赖于其他帧进行图像生成和呈现；P帧仅仅包含相对于前面的帧的图像变化信息，接收方(如终端)需要结合前面的帧来生成当前帧，在接收方完成显示；B帧用以指示当前帧相对于前面的帧和后面的帧的变化信息。接收方需结合前面的帧和后面的帧生成当前帧。
通常，不同的图像帧类型对应的数据量不同，例如，I帧的数据量最大，P帧的数据量居中，而B帧的数据量最小。在图像帧类型对应的数据量越大时，则图像帧需要的传输时长也越长；在图像帧类型对应的数据量越小时，则图像帧需要的传输时长也越短。
该实施例提到的图像帧类型与DRX激活窗长度相匹配，可以是图像帧类型与DRX激活窗长度正相关，例如：图像帧类型对应的数据量越大，则 DRX激活窗长度越大，使得终端能够在DRX激活窗长度内完成图像帧的接收，避免终端来不及接收完一个图像帧就进入休眠状态，避免图像帧传输超时；反之，图像帧类型对应的数据量越小，则DRX激活窗长度越小，终端休眠态的时长就越长，降低终端功耗。
在S202中，在图像帧类型为多个时，终端可以确定出与每一个图像帧类型分别相匹配的DRX激活窗长度，该DRX激活窗长度可以是终端在DRX配置中处于激活态的时间窗的长度。
需要说明的是，本申请各个实施例提到的DRX激活窗的长度可以由DRX配置中的drx-onDurationTimer和drx-InactivityTimer这两个参数中的至少一个确定；或者，还可以由drx-onDurationTimer、drx-InactivityTimer和一个与图像帧类型对应的激活窗长度调整参数来确定。
S204：终端在所述DRX激活窗长度内接收图像帧。
该实施例例如，S202中终端确定出与I帧相匹配的第一DRX激活窗长度，S204中终端在第一DRX激活窗长度内接收I帧；S202中终端确定出与P帧相匹配的第二DRX激活窗长度，S204中终端在第二DRX激活窗长度内接收P帧；S202中终端确定出与B帧相匹配的第三DRX激活窗长度，S204中终端在第三DRX激活窗长度内接收B帧；其中，第一DRX激活窗长度大于第二DRX激活窗长度，第二DRX激活窗长度大于第三DRX激活窗长度。
本申请实施例提供的图像帧的传输方法，终端可以确定出与图像帧类型相匹配的DRX激活窗长度，并在确定出的DRX激活窗长度内接收图像帧。由于图像帧类型与DRX激活窗长度相匹配，可以避免终端功耗增加或图像帧传输超时，有利于减少终端功耗，提高图像帧的传输质量。
本申请实施例提供的图像帧的传输方法可以应用在基于帧集合传输图像帧的技术方案中，其中，该技术方案可以根据视频流的周期性特性，按照I帧的周期将视频帧划分为视频帧组合，一个I帧和其后的到下一个I帧之前的所有的P帧和B帧，构成一个帧组合(Group of Picture，GoP)，具体可以参见图3最上面的部分。图像帧按帧周期进行传输和在接收方(如终端)进 行播放，相邻图像帧的帧到达时间之间的时间间隔为一个帧周期，基于帧集合的传输方式避免了图像帧之间的混合传输，使得生成的图像帧得到及时的传输。
可选地，实施例200中提到的终端确定与图像帧类型相匹配的DRX激活窗长度包括：终端根据第一DRX配置确定与图像帧类型相匹配的DRX激活窗长度；其中，所述第一DRX配置包括多个不同的DRX激活窗长度，所述多个不同的DRX激活窗长度分别和多个不同的图像帧类型相匹配。
该实施例中，终端确定与图像帧类型相匹配的DRX激活窗长度之前，终端还可以接收如下至少之一：所述第一DRX配置；所述多个不同的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。
在一个例子中，终端接收第一DRX配置，终端可以获知第一DRX配置包括多个不同的DRX激活窗长度，终端根据后续将要接收的多个图像帧类型，按照图像帧类型与DRX激活窗长度正相关的原则，可以自主确定多个不同的DRX激活窗长度与多个不同的图像帧类型的映射关系。
在另一个例子中，终端接收第一DRX配置，同时还可以接收所述多个不同的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。
上述多个实施例中，终端根据第一DRX配置确定与图像帧类型相匹配的DRX激活窗长度，可以采取如下方案之一：
方案1：终端根据图像帧类型，从所述多个不同的DRX激活窗长度中确定与所述图像帧类型相匹配的DRX激活窗长度。
方案2：终端根据激活窗模板确定DRX激活窗长度，其中，所述激活窗模板包括所述多个不同的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。

2)接收承载所述图像帧类型对应的图像帧数据的逻辑信道标识，所述逻辑信道标识和所述图像帧类型存在映射关系。
该例子中，终端可以先启动DRX激活窗长度对应的DRX激活窗，以接收图像帧数据，在接收的过程中确定图像帧类型，然后再确定DRX激活窗长度，在DRX激活窗长度之后进入休眠态。
3)接收图像帧类型周期模板配置，所述图像帧类型周期模板配置用于所述终端确定多个不同的图像帧类型。
该例子中，图像帧类型周期模板配置可以参见图3最上面的GOP示例，图3中，一个GOP内的多个图像帧是按固定周期发送的，终端根据图像帧类型周期模板配置，即可确定出在什么时刻接收什么图像帧类型的图像帧。例如，在GOP内的第一个周期接收I帧，在第二个周期接收P帧，在第三个周期接收B帧，在第四个周期接收P帧，等等。
可选地，实施例200中提到的终端确定与图像帧类型相匹配的DRX激活窗长度包括：终端根据所述图像帧类型从多个DRX配置中确定第二DRX配置，所述第二DRX配置的DRX激活窗长度和所述图像帧类型相匹配；其中，所述多个DRX配置的DRX激活窗长度分别和多个不同的图像帧类型相匹配。终端确定出第二DRX配置之后，还可以使用第二DRX配置接收所述图像帧类型对应的图像帧数据。
该实施例中，多个DRX配置中的每个DRX配置可以包括一个DRX激活窗长度，所述多个DRX配置包括的DRX激活窗长度可以各不相同。在同一时刻，通常只有一个DRX配置生效，其他的DRX配置处于不生效(或未激活)状态。
该实施例中，终端确定与图像帧类型相匹配的DRX激活窗长度之前，终端还可以接收如下至少之一：所述多个DRX配置；所述多个DRX配置的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。
在一个例子中，终端接收所述多个DRX配置，终端可以获知所述多个DRX配置包括的多个不同的DRX激活窗长度，终端根据后续将要接收的多个图像帧类型，按照图像帧类型与DRX激活窗长度正相关的原则，可以自主确定多个DRX配置的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。
在另一个例子中，终端接收所述多个DRX配置，同时还可以接收所述多个DRX配置的DRX激活窗长度与所述多个不同的图像帧类型的映射关系。
该实施例中，终端确定与图像帧类型相匹配的DRX激活窗长度之前，所述方法还包括：所述终端根据如下至少之一确定所述图像帧类型：
1)接收的第一指示信息，所述第一指示信息用于指示所述图像帧类型。
该第一指示信息可以是网络侧设备在DRX激活窗长度之前发送，例如，网络侧设备在唤醒信号中携带该第一指示信息，该唤醒信号用于终端启动DRX激活窗长度对应的DRX激活窗。
2)接收承载所述图像帧类型对应的图像帧数据的逻辑信道标识，所述逻辑信道标识和所述图像帧类型存在映射关系。
该例子中，终端可以先启动DRX激活窗长度对应的DRX激活窗，以接收图像帧数据，在接收的过程中确定图像帧类型，然后再确定DRX配置对应的DRX激活窗长度，在DRX激活窗长度之后进入休眠态。
3)接收图像帧类型周期模板配置，所述图像帧类型周期模板配置用于所述终端确定多个不同的图像帧类型。
该例子中，图像帧类型周期模板配置可以参见图3最上面的GOP示例，图3中，一个GOP内的多个图像帧是按固定周期发送的，终端根据图像帧类型周期模板配置，即可确定出在什么时刻接收什么图像帧类型的图像帧。例如，在GOP内的第一个周期接收I帧，在第二个周期接收P帧，在第三个周期接收B帧，在第四个周期接收P帧，等等。
上述图像帧类型包括如下至少之一：I帧，P帧，B帧。
在一个例子中，所述I帧、所述P帧和所述B帧对应的DRX配置的周 期和偏移是分别按图像帧的周期和到达时间配置的，所述I帧、所述P帧和所述B帧分别对应的DRX激活窗长度不同。
在一个例子中，所述I帧对应的DRX配置的周期和偏移是按图像帧的周期和到达时间配置的，因为I为周期性到达；所述P帧和所述B帧对应的DRX配置的偏移是分别按图像帧的到达时间配置的。
该实施例中，虽然配置了多个DRX配置，但终端可以根据图像帧类型确定与图像帧类型相匹配的DRX配置，确定出的DRX配置生效，其他的DRX配置处于不生效(或未激活)状态，避免多个DRX配置之间出现冲突，提高通信有效性。
可选地，在前文各个实施例的基础上，还可以包括如下步骤：在所述终端发送了解码器刷新请求的情况下，所述终端发送第二指示信息，所述第二指示信息用于网络侧设备确定视频业务配置将要更新和/或确定所述终端DRX状态(或称配置)改变。
该实施例中，当终端发送了解码器刷新请求后，服务器的视频源端可能会发即时解码刷新(Instantaneous Decoding Refresh，IDR)帧和/或用于图像帧解压缩的参数信息和辅助信息，这些数据不一定会遵循之前的发送图像帧到达时间，原有配置的DRX配置可能不再适用，因此，网络侧设备(如基站)接收到第二指示信息后，可以等待来自视频源端或5G-核心网(Core Network，CN)的图像帧帧的类型和到达时间信息，重新对终端进行DRX配置。
可选地，在所述终端发送了解码器刷新请求之后，所述方法还包括：所述终端退出DRX状态；其中，所述终端退出DRX状态后保持连续接收状态，以便于接收IDR帧和/或用于图像帧解压缩的参数信息和辅助信息。
可选地，所述第二指示信息用于向网络侧设备指示如下至少之一：所述终端退出DRX状态；所述终端发送了解码器刷新请求。
该实施例中，终端基于视频解码器刷新触发调整DRX配置，避免DRX配置对处于视频解码器刷新阶段的终端的视频数据和视频解码参数的传输造 成延时。
为详细说明本申请实施例提供的图像帧的传输方法，以下将结合几个具体的实施例继续说明。
实施例一
该实施例中，一个第一DRX配置包括有多个不同的激活窗长度，不同类型的图像帧对应不同的激活窗长度，终端和网络侧设备可以根据图像帧类型确激活窗长度。
该实施例例如，I帧对应长激活窗长度，B帧对应短激活窗长度，而P帧对应的激活窗长度在上述两者之间。
图3中显示的一个图像集合GOP包含3种类型的图像帧，即：I帧、P帧和B帧，相邻的图像帧之间的时长为图像帧的周期。如图3所示，I帧对应长激活窗长度，B帧对应短激活窗长度，P帧对应激活窗长度在两者之间。
该实施例中，终端可以采用如下两种方法之一来确定与图像帧类型相匹配的激活窗长度：
1)终端根据图像帧类型确定激活窗长度。该实施例中，基站可以配置3种激活窗长度，分别对应I帧、P帧和B帧，由终端根据一个图像帧的类型确定该激活窗的长度。终端可以根据到达的图像帧类型信息动态确定激活窗长度。对于下行XR业务，基站可以根据高层指示信息确定图像帧的类型，并把图像帧类型信息指示给终端，例如，基站可以使用媒体接入控制控制单元(Media Access Control-Control Element，MAC CE)或物理下行控制信道(Physical Downlink Control Channel，PDCCH)里的指示位将图像帧类型信息指示给终端，终端根据图像帧类型确定激活窗长度。
2)半静态确定激活窗长度：对于下行XR业务，由高层，例如5G-CN将XR业务的GOP模板告知给基站，GOP模板按顺序指示一个图像集合GOP内的图像帧类型，基站根据GOP模板为终端配置激活窗模板。
该实施例在执行时可以包括如下步骤：
步骤1：基站给终端预配置多个激活窗的长度，同时还可以配置图像帧 类型与激活窗长度的对应关系；
步骤2：基站向终端通知图像帧类型，可以按以下方式之一：
1)动态方式：基站在激活窗的开头使用PDCCH或MACCE告知终端将要接收的图像帧类型；或终端基于接收到的数据的逻辑信道标识(Identity，ID)与图像帧的对应关系来确定数据对应的图像帧类型。
2)半静态方式：基站把图像帧的模板通知给终端，例如一个I帧到下一个I帧之前的所有的图像帧的类型，包括图像帧的周期，GoP的大小(size)，等。终端基于预设参数确定将要接收的图像帧类型和对应的激活窗长度。
步骤3：终端确定与图像帧类型相匹配的激活窗长度。
步骤4：终端在确定出的激活窗长度内接收图像帧。
其中，步骤3和步骤4可以多次循环执行。
实施例二
该实施例中，终端从多个DRX配置中选择第二DRX配置。
该实施例针对I帧、P帧和B帧各配置一个DRX配置，分别对应不同的图像帧类型，终端或基站根据当前到达的图像帧类型确定一个当前应该遵行的DRX配置。
在一个例子中，I帧、P帧和B帧帧的DRX周期和偏移均按图像帧的周期和到达时间配置，但是不同类型的图像帧的激活窗(可以由参数drx-onDurationTimer配置)长度不同，终端根据当前图像帧类型确定生效的DRX配置(其他DRX配置对当前图像帧处于非激活状态)，从而确定对应的激活窗长度，即当I(或P，B)帧出现时，按与I(或P，B)帧对应的DRX确定激活窗长度。
在另一个例子中，对于I帧，配置一个匹配I帧周期和到达时间的DRX配置；对于P帧和B帧，各配置一个匹配P帧和B帧到达时间的DRX配置，终端或基站根据当前图像帧的类型确定生效的DRX配置(其他DRX配置对当前图像帧处于非激活状态)，从而确定对应的激活窗长度。
该实施例在执行时可以包括如下步骤：
步骤1：基站给终端预配置多个DRX配置，还可以配置图像帧类型与DRX配置的对应关系。
步骤2：基站给终端通知图像帧类型，可以按以下方式之一：
1)动态方式：基站在激活窗的开头使用PDCCH或MACCE告知终端将要接收的图像帧的类型；或终端基于接收到的数据的逻辑信道ID与图像帧的对应关系来确定数据对应的图像帧类型。
2)半静态方式：基站把图像帧类型的周期模板通知给终端，例如一个I帧到下一个I帧之前的所有的图像帧类型。
步骤3：终端基于预设参数确定适用于将要接收的图像帧类型的DRX配置。
实施例三
该实施例中，当终端请求解码器刷新时，视频源端可能会发一个IDR帧和或用于图像帧解压缩的参数信息和辅助信息，这一帧不一定会遵循之前的发送图像帧到达时间，原有配置的DRX配置可能不再适用。当终端发送解码器刷新请求后，向基站报告已经触发解码器刷新请求的信息，基站接收到这一消息后，等待来自视频远端或5G-CN的视频帧的帧类型和到达时间信息，重新配置终端的DRX配置。
可选地，终端在触发这一消息后，主动退出DRX状态，准备接收IDR帧和图像帧解压缩的参数信息和辅助信息。
可选地，基站可以预配置解码器刷新请求为终端退出DRX状态的条件，终端可以向基站报告退出DRX状态，并在报告中指示解码器刷新请求。
以上结合图2详细描述了根据本申请实施例的图像帧的传输方法。下面将结合图4详细描述根据本申请另一实施例的图像帧的传输方法。可以理解的是，从网络侧设备描述的网络侧设备与终端的交互与图4所示的方法中的终端侧的描述相同，为避免重复，适当省略相关描述。

该实施例中，每个所述第二DRX配置包括一个DRX激活窗长度，所述多个第二DRX配置的DRX激活窗长度可以各不相同。
在本申请实施例中，网络侧设备发送第一DRX配置或发送多个第二DRX配置，使得终端可以确定出与图像帧类型相匹配的DRX激活窗长度，以在确定出的DRX激活窗长度内接收图像帧。由于图像帧类型与DRX激活窗长度相匹配，可以避免终端功耗增加或图像帧传输超时，有利于减少终端功耗，提高图像帧的传输质量。
可选地，作为一个实施例，所述方法还包括：所述网络侧设备发送第一指示信息，所述第一指示信息用于指示图像帧类型。
可选地，作为一个实施例，所述方法还包括：所述网络侧设备接收第二指示信息，所述第二指示信息是终端在发送了解码器刷新请求的情况下发送的；所述网络侧设备根据所述第二指示信息确定视频业务配置将要更新和/或确定所述终端DRX状态改变。
