Description

一种通信方法、装置及系统 技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
未来依托于无线通信的新业务需求中，增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)、车联网、远程医疗、工业控制、电力传输通信等，相比于传统的视频传输等移动宽带(mobile broadband，MBB)业务来说，对于传输时延和传输可靠性提出了更高的需求。
以车辆连接一切(vehicle to everything，V2X)通信方式举例，车载应用的多样化，使得车内通信节点数量、类型都越来越多，对于车载通信的能力提出了更高的要求。由于相比现有的有线通信，车载设备之间采用无线通信可以进一步降低车内线束数量、长度、重量，以及与之对应的安装、维护、保养成本。目前，针对无线通信方式下，如何支持不同业务的数据传输仍需要研究。
发明内容
本申请提供一种通信方法、装置及系统，用于提高不同业务的数据的传输性能，满足不同业务的需求。
第一方面，本申请提供一种通信方法，根据第一编码方式对第一数据进行编码；发送编码后的第一数据；根据第二编码方式对第二数据进行编码，第一数据和第二数据不同，第二编码方式与第一编码方式不同；发送编码后的第二数据。
该方法可由第一通信装置执行，第一通信装置为发端装置。第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片。示例性地，当该通信方法应用于车辆时，所述第一通信装置可以为车载设备，或者为设置在车载设备中的用于实现车载设备的功能的芯片，或者为用于实现车载设备的功能的其他部件。也可以为终端设备，或者为设置在终端设备中的用于实现终端设备的功能的芯片，或者为用于实现终端设备的功能的其他部件。
在本申请实施例中，通过设置第二编码方式与第一编码方式不同，可以通过不同的编码方式对不同的数据进行编码，即根据第一编码方式对第一数据进行编码，根据第二编码方式对第二数据进行编码。从而可以更好的适应不同数据的对应的不同的业务需求，提高不同业务的数据的传输性能。
一种可能的实现方式，所述第一编码方式为里德-所罗门(reed-solomon，RS)编码方式。根据RS编码方式对第一数据进行编码，即对第一数据进行RS编码。
通过上述方法，在第一数据对时延要求较高时，可以选择第一数据的编码方式为RS编码方式。由于RS编码方式相比无线通信常用的编码方式，编码时延更短，可以满足业务极低时延的需求。另外，RS编码方式同时还具有错误数据的检出能力，通过RS编码方式，可以直接确定出当前接收到的数据是否出现错误，从而避免了现有技术中的编码方式还需其他校验方式(例如，循环冗余校验(cyclic redundancy check，CRC))才能确定数 据是否出现错误，所产生的额外的开销。
一种可能的实现方式，所述第二编码方式为极化(polar)编码方式。根据polar编码方式对第一数据进行编码，即对第一数据进行polar编码。
通过上述方法，第一通信装置为第二数据选择极化(polar)编码方式，相比RS编码方式性能更好。即在相同码率下相比RS编码方式的编码复杂度更高，可靠性较高；或者选择的编码方式相比RS编码方式可以达到相同可靠性，但是该编码方式的码率更高，对应的谱效率更高可以提高第二数据的传输性能，提高资源的有效利用，及提高链路性能。例如，可以选择的编码方式。

通过上述方法，第一通信装置可以根据第一数据的业务类型、优先级或传输模式中的至少一种，确定第一数据的第一编码方式。第一通信装置可以根据第二数据的业务类型、优先级或传输模式中的至少一种，确定第二数据的第二编码方式。例如，业务类型可以根据数据的时延需求进行划分，可以使得不同业务类型的数据对应不同的编码方式。进而第一通信装置可以在不同的业务场景中，确定出数据所适用的编码方式，并根据该编码方式对该数据进行编码，提高了该通信方法的适用性。
一种可能的实现方式，所述第一数据为降噪业务数据，或者，所述第一数据包含降噪业务数据，或者，所述第一数据包括降噪业务数据。

一种可能的实现方式，所述第二数据为多媒体业务数据，或者，所述第二数据包含多媒体业务数据，或者，所述第二数据包括多媒体业务数据。

具体实施方式
下面将结合附图，对本申请实施例进行详细描述。
下面首先对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)驾驶舱域控制器(cockpit domain controller或control domain cockpit，CDC)：也可以称为车机。车机的功能可以包括收音机、音乐视频播放、导航等驾驶舱中的功能，还可以包括蜂窝通信功能(3G，4G等)，实现人与车，车与外界的信息通讯，增强了用户体验及服务、安全相关的功能。
2)主节点、从节点：在逻辑功能上区分的两类具有通信功能的通信装置，分别称为主节点和从节点。主节点可以管理通信域的资源，并具有为主节点和从节点之间的通信链路调度资源的功能。主节点管理从节点，具有分配资源的功能，负责分配主节点和从节点之间通信的资源；从节点听从主节点的调度，使用主节点分配的资源与主节点通信。主节点或从节点可以为各种通信装置，例如主节点为手机，从节点为耳机，手机与耳机建立通信连接实现数据交互。手机管理耳机，手机具有分配资源的功能，可以为耳机分配与该手机通信的资源。
3)通信域：一组具有通信关系的通信装置，以及通信装置之间的通信连接关系组成的系统。通常，一个通信域包括一个主节点和至少一个从节点，主节点和从节点使用主节点调度的资源通信。一个通信装置可以属于多个通信域中。例如，当手机与耳机进行无线通信时，手机在包括手机与耳机在内的通信域a中，在通信域a中手机为主节点，耳机为从节点，手机调度的资源可以用于手机与耳机通信；然后当手机检测到CDC，并与该CDC建立无线连接后，手机也在包括手机与CDC在内的通信域b中，在通信域b中CDC为主节点，手机为从节点，CDC调度的资源可以用于CDC与手机通信。通信域b中还可以包括其他从节点，如车载音箱、麦克等。
4)主从节点间通信：主从节点间通信包括主从节点间通过资源进行信号、信令、业务数据的传输。所述资源可以包括时域资源、频域资源或码域资源中的至少一种。所述信号包括具有同步、信道估计、信道探测、相位跟踪、定位、接入等一种或多种功能的信号；所述信令包括物理层信令和/或高层信令；所述传输包括主节点发送从节点接收的传输(简称下行传输)和从节点发送主节点接收的传输(简称上行传输)。根据接收节点的数量和范围，传输可分为单播、组播、广播。下行传输可以为单播、组播或广播：接收的从节点为一个特定的从节点的下行传输为单播；接收的从节点为特定节点组中的所有从节点的下行传输为组播，从节点组由至少一个从节点组成；接收从节点为通信域中所有从节点的下行传输为广播。上行传输一定是单播，这是因为上行传输的接收节点是主节点，通信域中有且只有一个主节点。
5)里德-所罗门(reed-solomon，RS)编码：一种前向纠错的信道编码。RS编码与低密度奇偶校验码(low density parity check code，LDPC)编码、polar编码等无线通信常用编码相比，RS编码方式的编码时延和解码时延更短，可以满足业务极低时延的需求。RS编码方式同时还具有错误数据的检出能力，通过RS编码方式，可以直接确定出当前接收到的数据是否出现错误，从而避免了现有技术中的编码方式还需其他校验方式(例如，CRC) 才能确定数据是否出现错误，所产生的额外的开销(例如CRC校验比特)。
RS编码的参数可以包括：码元长度m比特，编码前母码码元个数k，编码后母码码元个数n，截断码元个数l，其中0<k<n<2 m+2，且通常n＝2 m-1。针对一个单独编码的数据块中，编码前数据块的大小为m×(k-l)比特，编码后编码块的大小为m×(n-l)比特。其中，m为码元长度，k编码前母码码元个数，n为编码后母码码元个数，l为截断码元个数。
本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一消息和第二消息，只是为了区分不同的消息，而并不是表示这两种消息的优先级、发送顺序或者重要程度等的不同。
下面介绍本申请实施例所应用的网络架构。请参考图1a为本申请实施例所应用的一种网络架构。图1a所示，车辆可采用电子电气(electrical/electronic，E/E)架构，也可以中央计算架构(central computing architecture，CCA)。在该网络架构下，本申请涉及的通信装置可以为车载设备。其中，车载设备，可以是放置或安装在车辆上的具有通信功能的设备。对于能够执行自动驾驶功能的车辆来说，可以通过传感器等车载设备采集的信息经过ADAS系统、移动数据中心(mobile data center，MDC)等处理后实现驾驶决策。另外，一辆车的车内网络可以包括多个电子控制单元(electronic control unit，ECU)，这些ECU都可以认为是车载设备。车辆内的传感器等车载设备采集的信息还可以通过ECU对数据处理后，再发送给高级驾驶辅助系统(Advanced Driving Assistance System，ADAS)的处理器或MDC的处理器中进行处理。车载设备可以为车机、车载扬声器、车载麦克风等车载设备。或者，如下介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，或者称为车载设备。作为示例而非限定，在本申请实施例中，放置或安装在车辆上的车载设备还可以包括可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
为提高对车辆内的车载设备的管理和控制，可以根据子系统将车载设备分为若干个通信域(domain)，每个通信域可以有一个域控制器，每个通信域包括一个或多个车载设备，每个通信域有一个域控制器(domain controller，DC)，域控制器用于管理通信域内的车载设备，而关于域控制器，例如随机选择通信域内的一个车载设备作为域控制器，或者也可 以选择通信域内的有统筹管理功能的一个车载设备作为域控制器。域控制器的设备类型可以和通信域内的一种设备的类型相同，或者，域控制器的设备类型和域内的设备的类型均不相同。例如，传感器系统(例如，可以包括ADAS传感器)构成一个通信域，其域控制器是MDC。行进系统可以分为一个通信域(例如，智能驾驶系统通信域)、传感器系统可以分为一个通信域、控制系统可以分为一个通信域(整车控制系统通信域)、外围设备可以分为一个通信域(例如，娱乐系统通信域)。在将车载设备划分为多个通信域时，划分因素可能有多种。例如可以根据车载设备所完成的功能来进行划分。例如有几个车载设备用于协同完成某种功能(例如，动力功能)，就可以将这几个车载设备划分为一个通信域。或者也可以按照其他因素来划分不同的通信域，在此不做限定。例如，通信域还可以根据车载设备所在车辆内的空间位置划分，还可以根据车载设备所在车辆内的空间位置和车载设备协同完成的功能等因素划分。
为减少车载设备间的线束，在本申请中，多个车载设备之间可以以通信域的方式实现无线通信。在一定通信区域或范围内可能存在一个或多个通信域。例如，图1a所示的第一通信域、第二通信域和第三通信域。该通信系统可以包括至少一个主节点。主节点可以是与从节点通信的车载设备，每个主节点可以为通信域内的从节点提供资源调度，并且可以与位于该通信域内的从节点进行通信。其中，第一通信域中，包括一个主节点(例如，第一通信装置1)，还可以包括至少一个从节点，例如，第三通信装置1。第一通信装置1与第三通信装置1建立通信连接，形成第一通信域。第二通信域中，包括一个主节点，第二通信装置1，第二通信装置1可以是车内无线通信场景中的对通信资源进行分配、协调等控制管理的设备。还包括多个从节点，例如第四通信装置1、第四通信装置2和第四通信装置3。第二通信装置1与至少一个第四通信装置1-3建立通信连接，形成第二通信域。第三通信域中，包括一个主节点，例如第五通信装置1，还包括多个从节点，例如第六通信装置1和第六通信装置2。第五通信装置1与至少一个第六通信装置1-2建立通信连接，形成第三通信域。
需要说明是，图1a仅是示意图，不作为对本申请的限定。本申请实施例的场景架构还可以只包括一个通信域，或者还可以包括更多通信装置形成的通信域，本申请不作限制。再比如，车辆架构包括的通信域的数量和通信域内的通信装置的数量均可以比图1a所示的多，也可以比图1a所示的少。另外，本申请所描述的系统架构是为了更加清楚的说明本申请的技术方案，并不构成对本申请提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变，本申请提供的技术方案对于类似的技术问题，同样适用。
在一种可能的场景中，第一通信装置1与第二通信装置1的类型可以相同，例如第一通信装置1与第二通信装置1可以为DC。需要说明的是，主节点不限于域控制器，还可以是其他车载设备。例如，图1a所示的示例中，对于一个车辆来说，域控制器都与网关连接，可以认为网关是主节点，域控制器为从节点。例如，网关可以作为一个主节点，此时，域控制器可以作为网关的从节点。
另一种可能的场景中，第一通信装置1与第二通信装置的类型1可以不同，例如第一通信域中的第一通信装置1可以为手机，第一通信域中的第三通信装置可以包括：耳机和穿戴式设备，在第一通信域中，手机是主节点，耳机和穿戴式设备是从节点；第二通信域中的第二通信装置1可以为CDC。第三通信装置1可以为多种车载设备，例如耳机、手环等可穿戴式设备等车载设备。第二通信域中的第四通信装置1-3还可以为：显示屏、麦克、 音箱等车载设备。第四通信装置1-3也可以包括多个车载设备，例如车载音箱、车载麦克等设备。CDC是主节点，显示屏、麦克和音箱是从节点。再比如，第三通信域中的第五通信装置1可以为无钥匙进入及启动系统(passive entry passive start，PEPS)，第三通信域中的第六通信装置1可以为终端设备的钥匙，第六通信装置2可以为车钥匙。第三通信域中的第六通信装置1-2可以包括：车身控制模块(body control module，BCM)、手机钥匙和车钥匙等。其中，PEPS系统是主节点，BCM、手机钥匙和车钥匙是从节点。另外，一个通信域的主节点也可以作为另一个通信域的从节点，例如，第一通信域中的手机可以作为第二通信域的从节点。
再比如，主节点和从节点都可以为车载设备，例如，第一通信装置1可以为手机，第三通信装置1可以为耳机，手机与耳机建立通信连接实现数据交互。手机管理耳机，手机具有分配资源的功能，可以为耳机分配资源，从而建立手机与耳机的通信连接。
又例如，将本申请实施例提供的技术方案应用于V2X通信场景，那么可参考图1b，为本申请实施例的一种应用场景。图1b包括终端设备1和终端设备2，终端设备1和终端设备2可通过侧行链路(sidelink，SL)通信。在该场景下，用于调度资源的终端设备可以作为主节点，用于听从调度资源的终端设备可以作为从节点。

图1b和图1c都以终端设备是手机为例，本申请实施例的终端设备不限于此。
以车内无线通信场景为例，主节点和从节点之间传输的数据可以为业务数据，业务数据可以根据不同的业务类型分为不同的业务数据。
一种可能的方式，车载通信的业务数据可以包括极低时延的业务数据，下面统称为第一类业务数据。举例来说，音频数据传输中可以包括降噪业务数据，该业务数据包括：用于降噪的麦克采集环境中的噪声数据，并将噪声数据发送给CDC；以及，降噪业务还包含主节点到从节点的数据传输，例如CDC在接收噪声数据后，可生成与噪声数据的振幅相同、相位相反的数据，并将该数据发送给音箱，以实现降噪。降噪业务的业务量在几mbps到几十mbps，甚至更多，在车载通信的总体业务量中占比较高，需要用较多的资源传输。在该场景下，降噪业务包含从节点到主节点的数据传输。主节点可以为管理麦克风和喇叭的域管理器(例如是CDC)，从节点可以包括麦克风和喇叭。针对降噪业务数据，其业务数据量占到了几mbps到几十mbps，甚至更多的mbps，在总体业务量中占比较高，需要占用较多的资源传输。另外，降噪业务数据的单个数据包非常小，例如有效信息可以仅为16、24或32比特；时延需求非常高，例如时延需求约20us；周期性稳定，例如周期为1/48kHz(约20.83us)。在该时延要求下，无线通信中常用的数据编码方式，例如LDPC编码方式，polar编码方式等，由于编码方式的复杂性，编码和解码时延较高，无法满足降噪业务所需要的20us的极低时延的需求。另外，由于RS编码方式中，可以针对降噪业务数据的单次传输的数据进行纠错和错误的检出。在通信装置通过RS编码方式对接收的数据进行解码时，若错误的比特数在相应的纠错能力范围内，该通信装置可以直接根据RS编码方式对接收的数据进行纠错，以获取到正确的数据；若错误的比特数大于纠错能力范围小于检错能力范围，该通信装置可以识别出数据传输出现错误。若通信装置确定接收的数据出现错误，考虑到降噪业务数据发送的频次较高，相邻两次或相邻几次发送的降噪业务的数据的差别不大，通信装置可以通过前一次或前几次接收到的降噪业务的数据确定该次接收的降噪业务数据，例如复制前一次的数据作为该次接收端数据。相比现有的编码方式而言，无需其他错误检出的方式(例如，CRC校验等)即可以实现接收的数据的错误的检出，对于单个数据包很小(单个包大小例如为16bit、24bit或32bit)的降噪业务，可以显著降低额外的开销(例如CRC校验比特)。因此，本申请中，针对极低时延的业务数据，特别是降噪业务，可以为其配置RS编码方式；对于时延需求不高的业务数据，为保证数据的传输性能，提高资源的有效利用，及提高链路性能，可以采用其他编码方式对其他业务类型的 数据进行编码。
另一种可能的方式，车载通信的业务数据还可以包括音/视频业务、网页浏览、文件传输等多媒体业务的业务数据，下面统称为第二类业务数据，该类业务数据的数据包较大，可以达到几百至几千比特，且业务量在总体业务量中占比较高，但是，该类业务对时延的要求不高，因此，第二类业务数据的编码方式可以选择相比RS编码方式性能更好的编码方式，例如，可以选择的编码方式在相同码率下相比RS编码方式的编码复杂度更高，可靠性较高；或者选择的编码方式相比RS编码方式可以达到相同可靠性，但是该编码方式的码率更高，对应的谱效率更高。
再一种可能的方式，车载通信的业务数据可以包括动态的业务数据，下面统称为第三类业务数据。第三类业务数据可以是对时延需求不高的应用层消息(例如针对车载设备的操作指令(如音量调节操作等))，或者设备/网络层等接入层以上各层的控制消息(如设备故障上报消息)等类型的业务数据。该类型的业务数据的数据包大小在几十到几百比特量级，对时延需求不高(可以是毫秒级以上的时延)，或无明确时延需求；数据传输可能随机出现，无明显的周期性。针对该类型的业务数据，在总体传输量中占比较少。此时，为降低通信装置对编码方式选择的复杂度，针对该类型的业务数据的编码方式，可以选择与第一类业务数据或第二类业务数据的编码方式相同的编码方式。例如，可以选择RS编码方式，由于RS编码方式对通信装置的编码能力的要求不高，因此，在第三类业务数据的编码方式选择RS编码方式时，可以降低第三类业务数据的传输的复杂度。
需要说明的是，上述业务类型的分类仅为一种举例，在具体实施过程中，还可以根据其他方式对数据进行业务类型的划分，在此不做限定。
综上，考虑到不同业务类型下的数据仅使用一种编码方式传输数据或控制信令难以满足不同业务的需求。本申请提出一种通信方法，使用至少两种编码方式传输数据，实现了极低时延需求的业务数据(例如，第一业务类型的数据)的传输，并保证了其它业务类型的数据(例如，第二业务类型或第三业务类型)在传输过程中的链路性能和频谱效率。
为了便于理解本申请实施例的通信方法，下面具体以车内无线通信场景为例，进行说明。其他通信场景可以参考上述无线通信场景，在此不再赘述。接下来结合附图介绍本申请实施例提供的技术方案。该方法可由两个通信装置(或者说，两种通信装置)执行，这两个通信装置例如为第一通信装置、第二通信装置。为描述方便，下文中第一通信装置简称为第一装置，第一装置可以是图1a所示的任一个通信域中的任一个主节点，或者第一装置也可以是设置在图1a所示的任一个通信域中的任一个主节点中的芯片系统。第二通信装置简称为第二装置。第二装置可以是图1a所示的任一个通信域中的任一个从节点，或者第二装置也可以是设置在图1a所示的任一个通信域中的任一个从节点中的芯片系统。其中，第一装置与第二装置位于同一通信域。需要说明的是，本申请实施例的通信方法可以应用于单个通信域。当系统中存在多个通信域时，多个通信域中的至少一个通信域可以独立执行本申请实施例中的通信方法，下面以一个通信域为例进行说明。
针对下行传输数据场景(场景1)，以第一装置向第二装置发送第一数据和/或第二数据，第二装置接收第一装置发送的数据为例进行说明。此时，第一装置可以为主节点，第二装置可以为与第一装置位于同一通信域中的一个从节点。请参见图2，为该方法的流程图。包括以下步骤：
步骤201：第一装置根据第一编码方式对第一数据进行编码。
其中，第一装置在对第一数据进行编码之前，还可以确定第一数据的编码方式，即第一装置可以根据第一数据，确定第一数据的编码方式为第一编码方式。下面以方式1-方式3进行说明。
方式1，第一装置可以根据第一数据的业务类型，确定第一数据的编码方式为第一编码方式。
不同的业务类型的数据可以配置不同的编码方式。第一数据的业务类型可以通过多种方式确定，一种可能的实现方式，可以为数据的业务类型单独配置一个业务类型的标识，用于指示数据的业务类型，针对该业务类型的标识，可以对应配置该业务类型的编码方式，从而，第一装置可以根据第一数据的业务类型的标识，及对应配置的业务类型的编码方式，确定第一数据的编码方式。举例来说，针对极低时延的降噪业务(第一业务类型)，可以单独配置一个业务类型的标识1，针对流媒体的业务数据(第二业务类型)，可以配置一个业务类型的标识2，针对动态的业务数据(第三业务类型)，可以单独配置一个业务类型的标识3。一种可能的实现方式中，一种业务类型的数据可以对应一种编码方式，针对上述标识1-标识3，可以一一对应一种编码方式。或者，为减少配置编码方式的数量，一种或多种业务类型的数据可以对应一种编码方式。即不同的业务类型也可以对应至少2种编码方式。举例来说，系统中可以配置两种编码方式，包括：第一编码方式和第二编码方式。例如，针对标识1-标识2的数据的编码方式，可以配置为第一编码方式，针对标识3的数据的编码方式，可以配置为第二编码方式。举例来说，第一编码方式可以为RS编码方式，第二编码方式可以为polar编码方式等其他编码方式。在该场景下，可以根据数据的时延需求，对应数据的编码方式。例如，针对极低时延的业务类型的数据的编码方式，可以对应为第一编码方式，以满足该业务类型的数据的时延要求。针对无时延要求或时延要求不高的业务类型的数据的编码方式，可以对应为第二编码方式。以保证该类型业务数据的传输性能。另一种可能的实现方式中，还可以根据数据的业务类型中的单次传输量，确定对应的编码方式。例如，针对数据的数据包较小、单次传输量较低的数据，可以将其编码方式对应为第一编码方式，以提高传输效率。针对数据的数据包较大、单次传输量较高的数据，可以将其编码方式对应为第二编码方式，以提高传输性能。
方式2，可以通过为数据配置优先级，针对该数据对应的优先级，可以对应配置该优先级的编码方式。从而，第一装置可以根据第一数据的优先级，确定第一数据的编码方式为第一编码方式。
针对数据的优先级可以是第一装置根据数据的业务类型确定的方式，数据的优先级与数据的编码方式的对应关系，可以是根据数据的业务类型与数据的编码方式的对应关系确定的。结合方式1中的方案，若确定不同的业务类型对应第一编码方式和第二编码方式，则可以根据业务类型对应的优先级，确定优先级对应的第一编码方式和第二编码方式。举例来说，若确定数据的优先级包括第一优先级、第二优先级和第三优先级。第一优先级对应第一业务类型，第二优先级对应第二业务类型和第三业务类型，第三优先级对应第四业务类型，则可以确定第一优先级对应的数据的编码方式为第一编码方式，第二优先级和第三优先级对应的数据的编码方式为第二编码方式。
针对其他优先级的确定方式，可以单独配置优先级与编码方式的对应关系，在此不做限定。
方式3，可以通过为数据配置的传输模式，针对该数据对应的传输模式，对应配置该 传输模式的编码方式。从而，第一装置可以根据第一数据的传输模式，确定第一数据的编码方式为第一编码方式。
针对不同的传输模式下，第一装置在每个协议层中对发送的数据的数据包的处理不同，因此，也会影响对发送数据的传输时延。一种可能的传输模式，数据采用二层协议报文的透传，或三层协议报文的透传时，可以避免第一装置对数据的重新打包的过程，从而，在这类传输模式下，第一数据从第一装置传输至第二装置的时延较短，因此，可以为该传输模式的数据配置第一编码方式，以进一步降低数据传输的时延。另一种可能的传输模式，第一装置从高层收到数据的数据包后，通过对数据进行编码，生成编码后的数据包后，向下一协议层转发。数据经过每个协议层，可能都需要针对该协议层进行重新打包，以添加对应的包头，因此，在该传输模式下，数据传输可能会有较大的时延，可以针对该传输模式，对应配置第二编码方式。
再一种可能的传输模式，在每个不同的协议层转发时，每个协议层对数据包的处理中，可能需要等待其他数据同时发送，因此，可能需要设置等待时间，根据每个数据对应的业务承载的服务质量(quality of service，QoS)需求不同，例如不同的业务承载对时延的需求不同，有些业务承载对时延要求较高，有些业务承载对时延要求较低。根据不同的时延的需求，可以为不同的数据设置不同的等待时间。
另一种可能的传输模式，第一装置和第二装置之间传输的数据的数据包，在每个不同的协议层转发时，可以直接对该数据的数据包进行转发，因此，在每个协议层对数据的数据包的处理中，不需要设置等待时间，从而降低了数据的传输时延，在该传输模式下，也可以将该数据的编码方式设置为第一编码方式，从而提高数据的传输效率。
进一步的，第一装置可以对第二装置接收第一数据的传输资源进行调度，以使第二装置确定第一数据的编码方式为第一编码方式，或第二数据的编码方式为第二编码方式，具体的调度方式可以有多种，下面以方式a1-方式a3举例说明。
方式a1，如图3a所示，为本申请提供的一种通信方法的流程示意图。所述方法包括：
步骤301a：第一装置确定第一数据的编码方式。
具体的确定方式可以参考上述方式1-方式3，在此不再赘述。
步骤302a：第一装置向第二装置发送调度信令。该调度信令用于第二装置根据调度信令确定出第一数据的编码方式，从而对第一装置发送的第一数据进行解码。该调度信令可以为高层信令或物理层信令，在此不做限定。下面举例说明调度信令的发送方式。
一种可能的实现方式，调度信令中携带的指示信息可以包括以下至少一项：第一数据的业务类型、第一数据的优先级、第一数据的传输模式、第一编码方式等。
第一装置可以根据确定第一编码方式的方法，确定调度信令携带的指示信息。例如，若第一装置通过第一数据的业务类型，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括第一数据的业务类型。若第一装置通过第一数据的优先级，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括第一数据的优先级。若第一装置通过第一数据的传输模式，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括第一数据的传输模式。
或者，第一装置还可以根据确定第一编码方式后，根据其他方法确定调度信令携带的指示信息，在此不做限定。例如，若第一装置通过第一数据的业务类型，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括以下至少一项：第一数据的业务类型、 第一数据的优先级或第一数据的传输模式。若第一装置通过第一数据的优先级，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括以下至少一项：第一数据的业务类型、第一数据的优先级或第一数据的传输模式。若第一装置通过第一数据的传输模式，确定第一数据的编码方式，则调度信令中携带的指示信息可以包括以下至少一项：第一数据的业务类型、第一数据的优先级或第一数据的传输模式。
例如，该指示信息用于指示第一数据的编码方式为第一编码方式。举例来说，该指示信息可以占用第一字段，第一字段占用1bit，通过0指示第一编码方式，通过1指示第二编码方式。或者，第一字段占用2bit，通过0指示第一业务类型，通过1指示第二业务类型，通过3指示第三业务类型，通过4指示第四业务类型。或者，第一字段占用2bit，通过0指示第一优先级，通过1指示第二优先级，通过3指示第三优先级。或者，第一字段占用2bit，通过0指示第一传输模式，通过1指示第二传输模式，通过3指示第三传输模式。上述指示方式仅为举例，在具体应用中可以根据需要确定指示方式，在此不做限定。
在具体实施过程中，调度信令中携带的指示信息所占用的字段可以复用原有的调度信令中的字段，也可以单独为编码方式设置一个新的字段，在此不做限定。下面涉及到的调度信令中用于确定第一数据的编码方式的字段可以统称为第一字段。另一种可能的实现方式，第一字段中还可以直接指示第一数据的编码方式，即直接指示第一编码方式。
从而，第二装置接收到该调度信令后，可以确定出接收的第一数据的编码方式为第一编码方式，从而，根据第一编码方式对第一数据进行解码。
方式a2，如图3b所示，为本申请提供的一种通信方法的流程示意图。所述方法包括：
步骤301b：第一装置接收到第二装置发送的传输请求信令。
一种可能的实现方式，传输请求信令可以携带有第二装置确定的传输第一数据的传输信息，用于第一装置为第一数据确定传输资源和第一数据的编码方式。该传输信息可以占用第二字段，第二字段可以用于指示以下至少一项：所述第一编码方式、所述第一数据的优先级、所述第一数据的业务类型或者所述第一数据的传输模式。
其中，第二装置可以是第二装置根据自身采集的信道状态，或者，第二装置根据自身所支持的数据的编码方式、数据的业务类型、数据的传输模式等数据的配置参数，确定出第一装置和第二装置之间传输的第一数据对应的编码方式为第一编码方式。从而，第二装置通过传输请求信令，通知第一装置传输第一数据使用第一编码方式。
步骤302b：第一装置根据传输请求信令确定出第一数据的编码方式。
结合步骤301b中的第一种可能的实现方式中，举例来说，第一装置在接收到第二装置的传输请求信令后，根据传输请求信令确定第一数据的编码方式。
结合步骤301b中的第二种可能的实现方式中，第一装置可以根据传输请求信令中携带的第二字段，确定第一数据的编码方式为第一编码方式。
步骤303b：第一装置还可以向第二装置发送调度信令。
其中，该调度信令用于携带指示信息，该指示信息用于指示第一数据的编码方式为第一编码方式。该指示信息可以占用第一字段发送，也可以通过其他字段向第二装置发送该调度信令，在此不做限定。
方式a3，第一装置和第二装置可以通过预配置的方式，确定第一数据的编码方式为第一编码方式。其中，预配置的方式可以为协议规定的，也可以是第一装置在出厂时或维修保养等为第一装置配置的，第二装置在出厂时或维修保养等为第一装置配置的，当然还可 以是其他预配置的方式，在此不做限定。
例如，可以为不同的通信域配置不同的编码方式的集合，还可以在通信域中，针对不同的第一装置和第二装置所支持的业务类型，为第一装置和第二装置发送的数据对应的编码方式，此时，第一装置无需向第二装置发送调度信令指示的方式确定第一数据的编码方式，以节省信令开销。
在确定第一数据的编码方式为第一编码方式后，以第一编码方式为RS编码方式为例，在编码过程中，第一装置可以根据所述第一数据的数据包大小，确定RS编码方式中的编码参数，例如，可以根据数据包大小，确定出RS编码参数中的编码后母码码元个数n，截断码元个数l。从而根据编码后母码码元个数n，截断码元个数l，对所述数据进行编码。
步骤202：第一装置向第二装置发送编码后的第一数据。
其中，第一装置发送编码后的第一数据，可以是单播方式，也可以是广播方式、组播方式，在此不做限定。
步骤203：第一装置根据第二编码方式对第二数据进行编码。
其中，所述第一数据和所述第二数据不同，所述第二编码方式与所述第一编码方式不同。第一数据和第二数据可以根据多种方式确定为不同的数据，下面以示例1-示例3进行说明。
示例1，第一数据的业务类型和第二数据的业务类型不同，此时，第一装置可以根据数据的业务类型，确定该数据对应的编码方式。结合上述业务类型的分类，若为业务类型配置了对应的标识，则可以根据数据的业务类型的标识，确定第一数据的业务类型和第二数据的业务类型不同。结合上述业务类型与编码方式的对应关系，若第一数据为极低时延的业务类型，第一装置可以将第一数据的编码方式确定为第一编码方式，其中，第一编码方式可以为RS编码。若第一数据为动态的业务类型，第一装置可以将第一数据的编码方式确定为第二编码方式。
示例2，在不同的业务场景下，第一数据和第二数据还可能存在不同的配置参数，例如，为第一数据配置的传输资源与为第二数据配置的传输资源不同，因此，第一装置还可以根据第一数据配置的传输资源与第二数据配置的传输资源不同，确定第一数据与第二数据不同。其中，传输资源可以包括：时域资源、频域资源、码域资源等。
示例3，第一装置还可以根据数据的传输参数，确定第一数据和第二数据不同。
例如，数据的传输参数可以包括：调制编码方式、多输入多输出模式、自动请求重传参数、优先级、传输模式等。
需要说明的是，第一装置确定第二数据的编码方式的方法也可以有多种，具体可以参考步骤201中，第一装置确定第一数据的编码方式中的方式1-方式3的说明，在此不再赘述。
进一步的，第一装置在发送第二数据之前，还可以调度第二装置接收第二数据的传输资源，以使第二装置确定第二数据的编码方式为第二编码方式。具体实施方式可以参见方式a1-方式a3中第一装置与第二装置间的交互的说明，在此不再赘述。
步骤204：第一装置向第二装置发送编码后的第二数据。
其中，第一装置发送编码后的第二数据，可以是单播方式，也可以是广播方式、组播方式，在此不做限定。
需要说明的是，上述步骤203和步骤204可以是第一装置可选的步骤，可以不与步骤 201和步骤202同时执行，也可以不执行，也可以单独执行。也可以在步骤201和步骤202之前执行，也可以在步骤201和步骤202之后执行，也可以与步骤201和步骤202同时执行在此不做限定。因此，在图2中以虚框表示。
步骤205：第二装置接收数据。
其中，第二装置接收的数据可以为第一装置发送给第二装置的第一数据或第二数据。所述数据可以为上述实施例所述的任一种业务类型的业务数据。
步骤206：第二装置根据第一编码方式和/或第二编码方式对所述数据进行解码。
其中，所述第一编码方式属于至少两种编码方式中的一种。所述第二编码方式属于至少两种编码方式中的一种，第一编码方式与第二编码方式不同。
在步骤206中，第二装置可以通过多种方式确定第一编码方式或第二编码方式。下面以方式c1-方式c3举例说明。
方式c1，如图4a所示，所述方法包括：
步骤401a：第二装置接收第一装置发送的调度信令。
步骤402b：第二装置可以根据第一装置发送的调度信令，确定所述数据的编码方式为第一编码方式或第二编码方式。该调度信令可以用于第一装置确定第一装置发送的数据的编码方式。例如，在第一装置确定发送第一数据之前，可以在确定第一数据的编码方式为第一编码方式后，向第二装置发送调度信令。该调度信令可以包括第一字段。第一字段中所指示的内容可以参考图3a-图3b中的实施例，在此不再赘述。
一种可能的实现方式，在步骤203之前，第一装置确定第一数据的编码方式为第一编码方式，此时，第一装置可以向第二装置发送调度信令，该调度信令可以用于确定所述数据的编码方式为第一编码方式。从而，第二装置接收到该调度信令后，可以通过调度信令携带的指示信息，确定所述数据的编码方式为第一编码方式。其中，调度信令携带的指示信息可以参考图3a-图4b中实施例中的调度信令携带的指示信息，在此不再赘述。在第二装置确定所述数据的编码方式为第一编码方式后，第二装置可以根据第一编码方式确定相应的解码方式，从而对所述数据进行解码。例如，若确定第一编码方式为RS编码方式，则第二装置可以根据RS编码方式，确定出相应的RS解码方式，从而对所述数据进行解码。进一步的，第二装置还可以根据所述数据的数据包大小，确定RS编码方式中的编码参数，例如，可以根据数据包大小，确定出RS编码参数中的编码后母码码元个数n，截断码元个数l。从而根据编码后母码码元个数n，截断码元个数l，对所述数据进行解码。
方式c2，在第一装置发送数据之前，如图4b所示，所述方法包括：
步骤401b：第二装置向第一装置发送传输请求信令。
该传输请求信令可以用于向第一装置发送确定传输数据的传输资源的信息，或者，该传输请求信令可以用于指示第二装置所能接收的数据对应的编码方式，再比如，该传输请求信令还可以用于指示第二装置所能接收的数据的业务类型、传输模式等配置参数。从而，第一装置可以根据该传输请求信令确定所述数据的编码方式。一种可能的实现方式中，该传输请求信令可以包括第二字段，其中，第二字段可以用于指示以下至少一项：所述数据的编码方式，所述数据的业务类型，所述数据的传输模式，所述数据的优先级。举例来说，第二装置仅能支持第一编码方式，或者，第二装置所能接收的数据的业务类型包括降噪业务类型的音频数据，或者非降噪业务类型的音频数据。
步骤402b：第一装置向第二装置发送调度信令。
第一装置可以根据第二装置发送的传输请求指令，确定发送第一编码方式或第二编码方式，从而，第一装置可以向第二装置发送调度信令，该调度信令可以用于指示第一装置确定的所述数据的编码方式为第一编码方式或第二编码方式。
步骤403b：第二装置可以根据接收到的调度信令，确定第一数据的编码方式为第一编码方式。从而，根据第一编码方式对接收的数据进行解码。
或者，在第一装置向第二装置发送第二数据之前，第一装置可以根据第二装置发送的传输请求信令，确定发送第二数据的第二编码方式，从而，第一装置可以向第二装置发送调度信令，该调度信令可以用于指示第一装置确定的第一装置发送的第二数据的编码方式为第二编码方式。从而，第二装置可以根据接收到的调度信令，根据第二编码方式对接收的数据进行解码。具体发送传输请求信令和接收调度信令的方式可以参考方式b2中第二装置的实施方式，在此不再赘述。
方式c3，第二装置根据预配置的至少两种编码方式中的任一种方式作为第一编码方式，从而，第二装置可以根据确定的第一编码方式对所述数据进行盲检。举例来说，盲检过程可以为第二装置随机从至少两种编码方式中选择出的一种编码方式作为第一编码方式，对接收的数据进行解码，若第一编码方式解码成功，则停止尝试预配置的至少两种编码方式中的其他编码方式对接收的数据进行解码。若第一编码方式解码失败，则在预配置的至少两种编码方式中的其他编码方式中，随机选择一种编码方式对接收的数据进行解码，重复上述解码过程，直至采用其中一种编码方式可以成功解码接收到的数据。
或者，第二装置根据预配置的至少两种编码方式中的任一种方式作为第二编码方式，从而，第二装置可以根据确定的第二编码方式对所述数据进行盲检。在该方式下，无需第一装置为第二装置指示采用哪种编码方式对数据进行解码，可以有效的减少信令的开销。
一种可能的实现方式中，第一编码方式可以为RS编码方式，从而，第二装置可以先通过复杂度较低，时延较小的编码方式对数据进行解码，在所述数据为第一装置发送的第一数据，且第一数据的编码方式为RS编码方式时，可以及时对数据进行解码，以满足第一数据对时延的需求。
进一步的，第二装置还可以根据第二编码方式对所述数据进行解码。其中，第二编码方式可以为预配置的至少两种编码方式中的除第一编码方式以外的任一种方式。
需要说明的是，第二装置根据第二编码方式对数据进行解码的过程，与第二装置根据第一编码方式对数据进行解码的过程，可以是在步骤206中择一执行的，也可以在步骤206中顺序执行的。例如，第一装置同时发送第一数据和第二数据的场景，第一数据通过第一编码方式进行编码，第二数据通过第二编码方式进行编码。在该场景下，第二装置可以先通过第一编码方式对数据进行解码，若可以成功解码，则确定该数据为第一装置发送的第一数据。若无法成功解码，第二装置可以通过第二编码方式对数据进行解码，若可以通过第二编码方式进行解码，则确定该数据为第一装置发送的第二数据。再比如，还可以是第二装置随机选取第二编码方式或第一编码方式对接收到的数据进行解码的先后顺序，可以根据实际需要确定第二编码方式或第一编码方式对接收到的数据进行解码的先后顺序，在此不做限定。

举例来说，若第二装置仅能支持第一编码方式，或者，第二装置所能接收的数据的业务类型包括降噪业务类型的音频数据，或者非降噪业务类型的音频数据。
从而，在第二装置发送第一数据之前，第一装置可以根据第二装置发送的第一数据的配置参数，确定发送第一数据的第一编码方式，从而，第一装置可以向第二装置发送调度信令，该调度信令可以用于指示第二装置确定的所述数据的编码方式为第一编码方式。同时，第一装置可以根据第一编码方式对接收的数据进行解码。
方式d2，在第二装置发送数据之前，如图7b所示，所述方法包括：

步骤703b：第一装置向第二装置发送调度信令。该调度信令可以用于为第二装置分配第二装置发送第一数据或第二数据的传输资源和对应数据的编码方式(例如，可以包括第一数据的编码方式，第二数据的编码方式)。该调度信令可以包括第一字段。第一字段中所指示的内容可以参考图2中的实施例，在此不再赘述。
一种可能的实现方式，第一装置确定第二装置需要发送第一数据，此时，第一装置可以确定第一数据的编码方式为第一编码方式，从而，第一装置可以在第二装置发送第一数据之前，向第二装置发送调度信令，该调度信令可以用于确定所述数据的编码方式为第一编码方式。从而，第二装置接收到该调度信令后，可以通过调度信令携带的指示信息，确定所述数据的编码方式为第一编码方式。其中，调度信令携带的指示信息可以参考图2中实施例中的调度信令携带的指示信息，在此不再赘述。在第一装置接收到第二装置发送的数据后，第一装置可以根据确定的第一编码方式，确定相应的解码方式，从而对所述数据进行解码。具体解码方式可以参考场景1中的实施方式，在此不再赘述。
再比如，在第二装置向第一装置发送第二数据之前，第一装置可以根据第二装置发送的传输请求信令，确定发送第二数据的第二编码方式，从而，第一装置可以向第二装置发 送调度信令，该调度信令可以用于指示第一装置确定的第二装置发送的第二数据的编码方式为第二编码方式。同时，第二装置可以根据第二编码方式对接收的数据进行解码。具体发送传输请求信令和接收调度信令的方式可以参考方式c2中第二装置的实施方式，在此不再赘述。
方式c3，第一装置根据预配置的至少两种编码方式中的任一种方式作为第一编码方式，对所述数据进行盲检，在该方式下，第一装置无需确定第二装置采用哪种编码方式对数据进行编码，可以有减少第一装置确定编码方式所需的处理的复杂度，另外，也无需第一装置为第二装置发送调度信令可以有效减少信令的开销。

步骤902：第一装置接收第二装置发送的控制信令，并根据控制指令的编码方式对控制信令进行解码。
例如，该控制信令可以为本申请所涉及的任一种控制信令，在此不做限定。
