技术领域
本申请属于通信技术领域，具体涉及一种信息传输方法、装置、终端及网络侧设备。
背景技术
对于有时延要求的业务，例如扩展现实(eXtended Reality，XR)业务，XR业务有周期性的图像帧到达，对于基于帧集合(group of pitcture,GoP)的图像帧数据传输模型，有I帧、P帧和B帧，其中I帧的数据量最大、P帧的数据量其次，而B帧的数据量最小。I帧周期出现，两个I帧之间存在若干P帧和B帧。
如果一个小区存在多个传输XR业务的用户，且XR业务是基于GoP模型，若多个用户的XR业务的I帧出现的时间很接近，则需要很大的空口容量来发送这些I帧，可能导致出现网络拥塞；若网络拥塞解除，空口容量有较大空余，则可能造成空口资源浪费。也就是说，空口容量的利用不够有效，影响传输性能。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，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(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，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)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，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可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(Evolved Node B，eNB)、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)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，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系统中的基站为例进行介绍，并不限定基站的具体类型。
为便于更好的理解本申请实施例，现对扩展现实(eXtended Reality，XR) 业务相关内容进行如下简单介绍：
XR业务包括增强现实(Augmented Reality，AR)业务、虚拟现实(Vitual Reality，VR)业务和混合AR和VR(Mixed AR and VR，MR)业务。XR业务可采用H.264编码技术，实现图像数据压缩，实现节约流量和确保图像质量的目的。H.264技术可把图像数据编码为三种类型的图像帧：
帧内编码(Intra-coded picture，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；
前向预测(Predicted picture，P)帧，仅仅包含相对于前面的帧的图像变化信息，接收方需要结合前面的帧来生成当前帧，在接收终端上完成显示；
双向预测(Bidirectional predicted picture，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。
上述前面的帧和后面的帧指是按帧呈现时间或信源端的图像采集时间排序，实际的发送和接收时间可能根据接收方的图像解码时间有所调整，例如发送方可以根据接收方的图像帧解码时间顺序进行发送。
不同帧类型对应不同的帧编码方法，导致图像压缩的程度不同。其中I帧的压缩程度较低(即帧数据量最大)，P帧的压缩程度适中(即帧数据量适中)，B帧的压缩程度最高(即帧数据量最小)。
XR图像有两种传输方式，基于帧切片组合的传输方式和基于帧集合(group of pitcture,GoP)的传输方式。
基于帧切片组合的传组合输方式：把一个图像帧切成多个数据块，然后把多个图像帧的切块分散组合成多个数据块进行传输，达到XR业务数据流流量平滑的目的，这一方法大幅度减小了由于I帧、P帧、B帧数据量差异导致的流量波动，但是由于图像帧之间交叉传输、增加了图像帧的传输时延；
基于帧集合的传输方式：根据视频流的周期性特性，按照I帧的周期将视频划分为视频帧组合，一个I帧和相邻的下一个I帧之间的所有的P帧和B帧，构成一个帧组合。图像帧按帧周期进行传输和在接收方进行播放，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。由于I 帧、P帧、B帧之间的压缩程度不同，导致帧数据速率波动。
XR业务数据在NR网络中的数据传输，如图2a和图2b显示了XR业务数据在无线网络中的数据传输。其中图2a显示终端通过终端的调制解调器(即modem)经过无线网络从内容服务器获取XR业务数据。图2b显示的是两个终端之间的XR业务数据传输。终端的调制解调器和基站运行无线传输协议，完成XR业务数据传输。
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信息传输方法进行详细地说明。
请参见图3，图3是本申请实施例提供的一种信息传输方法的流程图，该信息传输方法，包括：
步骤301、终端获取传输参数信息，其中，所述传输参数信息用于确定视频业务数据的空口传输参数。
传输参数信息可以是终端自主生成，例如在视频业务数据传输速率较低的情况下生成，也可以是终端基于网络侧设备发送的第一速率调整请求生成。在端对端场景中，传输参数信息还可以是发送端发送给所述终端的，发送端为与所述终端进行视频业务数据端对端传输的一端，发送端可以为其他终端或者服务器。视频业务数据可以是XR业务数据。

本实施例中，终端获取传输参数信息，其中，所述传输参数信息用于确定视频业务数据的空口传输参数；所述终端向网络侧设备发送所述传输参数信息。由于网络侧设备可根据终端发送的传输参数信息确定空口传输参数，可使得空口传输参数与终端传输视频业务数据需求相匹配，从提高视频业务数据的传输性能。例如，在终端需要较大的空口容量来发送视频业务数据时，网络侧设备可通过调整空口传输参数来避免出现网络拥塞；在网络拥塞解除时，网络侧设备可通过调整空口传输参数来提高空口资源的利用率。
上述中，所述传输参数信息包括如下至少一项：

I帧的数据量范围，例如，I帧的最大数据量；
P帧的数据量范围，例如，P帧的最大数据量；
B帧的数据量范围，例如，B帧的最大数据量。
网络侧设备在收到传输参数信息后，根据所述传输参数信息，确定空口资源分配(即确定空口传输参数)，空口资源分配包括动态调度的上行资源分配、动态调度的下行资源分配、基于预配置下行资源分配、基于预配置的上行资源分配，非连续资源接收的参数配置、上行调度请求资源配置和信道质量汇报的配置等。
在本申请一种实施例中，在所述终端获取传输参数信息之前，所述方法还包括：

具体的，终端可包括调制解调器和应用层(也可称为XR应用层)，终端通过终端的调制解调器接收的第一速率调整请求，由于信息的传递规则和语法不同，调制解调器不能将接收到的第一速率调整请求直接发送给应用层，而是需要先依据所述第一速率调整请求生成第二速率调整请求，再将第二速率调整请求发送给所述终端的应用层，应用层基于所述第二速率调整请求，确定所述传输参数信息。进一步的，传输参数信息通过调制解调器发送给网络侧设备。
