具体实施方式
本申请实施例可以应用于无线通信系统，需要说明的是，本申请实施例提及的无线通信系统包括但不限于：窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)以及下一代5G移动通信系统。
本申请实施例的通信系统可以包括编码侧和译码侧，图1A为本申请一实施例提供的一种编译码的系统架构示意图，图1B为本申请另一实施例提供的编译码的系统架构示意图。如图1A和图1B所示，编码侧对待发送的数据进行编码和输出编码后序列，编码后序列在信道上传输至译码侧；译码侧可以接收编码侧发送的待译码序列(即编码后序列)，并对该待译码序列进行译码。
具体地，任何具有编码功能的设备都可以作为本申请实施例中的编码侧，任何具有译码功能的设备都可以作为本申请实施例中的译码侧。在一些可能的实现方式中，同一设备同时具有编码功能和译码功能，则该设备即可以作为编码侧，也可以作为译码侧。
以一个具体的例子为例，该设备可以为网络设备或者终端设备。如图1A所示，网络设备11作为编码侧向作为译码侧的终端设备12发送数据。如图1B所示，终端设备12作为编码侧向作为译码侧的网络设备11发送数据。
在本申请实施例中，终端设备(terminal device)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该终端设备可以经无线接入网(RAN，Radio Access Network)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。在不同的网络中终端可以叫做不同的名称，例如：用户设备，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台等。为描述方便，本申请中简称为终端设备。
网络设备可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，在新空口(new radio，NR)网络中收发点(transmission reception point，TRP)或者下一代节点B(generation nodeB，gNB)，或者该网络设备可以为中继站、接入点、车载设备、可穿 戴设备以及未来5G网络中的网络侧设备、基站或未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等，或者在其他多种技术融合的网络中的网络设备。
目前，在5G移动通信系统，采用的编码方式主要为Polar(极化)码编码方式和低密度奇偶校验(Low Density Parity Check，LDPC)编码方式。可选地，编码方式也可以称为编码方式。
在本实施例中，这里的Polar码包括但不限于Arikan Polar码、PC-Polar码、CA-Polar码、PC-CA-Polar码。Arikan Polar是指原始的Polar码，没有与其它码级联，只有信息比特和冻结比特。PC-Polar是级联了奇偶校验(Parity Check，PC)的Polar码，CA-Polar是级联了循环冗余校验(Cyclic Redundancy Check，CRC)的Polar码及其他级联Polar码。PC-CA-Polar码是同时级联了PC和CRC的Polar码。PC-Polar和CA-Polar是通过级联不同的码来提高Polar码的性能。
其中，Polar码是一种线性块码，其生成矩阵为G N，编码过程为u NG N＝x N，其中u N＝(u 1,u 2,...,u N)是一个二进制的行矢量，长度为N(即母码长度)；G N是一个N×N的矩阵，且
Figure PCTCN2019074507-appb-000001
这里矩阵
Figure PCTCN2019074507-appb-000002
定义为log 2N个矩阵F 2的克罗内克(Kronecker)乘积；以上涉及的加法、乘法操作均为二进制伽罗华域(Galois Field)上的加法、乘法操作。
Polar码的编码过程中，u N中的一部分比特用来携带信息，称为信息比特，这些比特的索引的集合记作A；另外的一部分比特置为收发端预先约定的固定值，称之为固定比特，其索引的集合用A的补集A  c表示。不失一般性，这些固定比特通常被设为0，只需要收发端预先约定，固定比特序列可以被任意设置。
Polar码基于串行抵消(Successive Cancellation，SC)译码算法或串行抵消列表(SC List，SCL)译码算法等进行译码，本实施例对polar码的译码算法不做特别限制。其中，SC译码算法，即从第1个比特开始顺序译码。串行抵消列表(SC List，SCL)译码算法是对SC译码算法的改进，在每个比特保留多个候选译码结果，完成全部比特的译码后根据一定准则对列表中所有译码结果进行选择，得到最终译码结果。所述准则可以是根据各列表的路径惩罚值进行排序，选择路径惩罚值最小的列表；也可以是CRC校验通过的列表作为最终输出。
低密度奇偶校验码(Low Density Parity Check，LDPC)码，是由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近香农极限的良好性能，而且译码复杂度较低、结构灵活。LDPC码本质上是一种线形分组码，它通过一个生成矩阵G将信息序列映射成发送序列，也就是码字序列。对于生成矩阵G，完全等效地存在一个奇偶校验矩阵H，所有的码字序列C构成了H的零空间(null space)。
目前LDPC码的编码方式主要有：二进制LDPC码的编码、基于高斯消去的编码、基于 近似下三角矩阵的编码以及基于循环码的编码等，对于LDPC码的编码方式的具体实现，本实施例此处不做特别限制。
在一个具体的示例中，基于基矩阵(base graph)构造的准循环低密度奇偶校验(Quasi-Cyclic Low Density Parity Check，QC-LDPC)码对应的校验矩阵具有描述简单，易于构造等优点。QC-LDPC的校验矩阵(parity check matrix)是对一个基矩阵进行扩展得到的，QC-LDPC的校验矩阵具有描述简单、易于构造等特点。在3GPP TS38.212.V15.0.0(2017-12)中，引入了LDPC的两种不同的基矩阵(base graph，BG)BG1和BG2进行LDPC编码，具体可以参见文献3GPP TS38.212.V15.0.0(2017-12)。
例如，矩阵H为校验矩阵，具体如下：
Figure PCTCN2019074507-appb-000003
其中a ij是循环移位矩阵的移位因子，n b和m b是基矩阵的列数和行数。Pa ij是循环移位矩阵，可以通过对I的单位阵循环移a ij位得到。其中a ij的范围是-1≤a ij＜Z。可定义Z×Z的全零矩阵O为P -1。如果H是满秩矩阵，则可以在基矩阵上(n b-m b)列放(n b-m b)Z个信息比特。我们称这K b＝(n b-m b)的基矩阵列为信息列。采用QC-LDPC码时，如果信息序列的长度K被K b整除，那么在扩展后的LDPC校验矩阵中每一个信息比特位置都用来放置信息比特；如果K不被K b整除，导致Z×K b＞K，那么在扩展后LDPC校验矩阵中会有(Z×K b-K)的多余信息比特位置，可称为填充比特。
常用的LDPC译码算法都基于消息传递算法(Message Passing Algorithms)。一类是复杂度较高的置信传播(Belief Propagation，BP)算法，通常用于仿真分析，无法用于实际系统；另一类是最小加和(min-sum，MS)算法，其复杂度较低，易于实现，这类算法包括分层归一化最小加和(Layered Normalized Min-Sum，LNMS)算法、分层抵消最小加和(Layered Offset Min-Sum，LOMS)算法等。
在一些可能的实现方式中，Polar码在码率较低、数据包大小较小时性能较好，而LDPC在码率较高、数据包大小较大时性能较好。而在5G中的超可靠低迟延通信(Ultra-reliable and low-latency communications，URLLC)场景中，为了满足URLLC场景多种业务场景的不同需求，可以在URLLC的数据信道使用混合的信道编码方式，根据具体场景和参数的不同，确定使用Polar编码方式还是LDPC编码方式作为信道编码方式。
由于编码侧进行编码，而译码侧进行译码，不同的编码方式对应的译码方案不同，因此译码侧需要知道编码侧的编码方式，从而采用该编码方式对应的译码方案，从而进行正确译码。由此，编码侧和译码侧对齐编码方式变得尤为重要。本申请实施例给出一种编码侧和译码侧对齐编码方式的实现方式。
图2为本申请一实施例提供的编码方式的指示方法的信令流程图。如图2所示，该方 法包括：
S201、第一设备获取编码方式指示，所述编码方式指示用于指示第一数据的编码方式和/或第二数据的编码方式；
其中，所述第一数据为所述第一设备向第二设备发送的数据，所述第一数据的编码方式为Polar编码方式或低密度奇偶校验LDPC编码方式，所述第二数据为所述第二设备向所述第一设备发送的数据，所述第二数据的编码方式为Polar编码方式或LDPC编码方式；
S202、所述第一设备向第二设备发送编码方式指示；
S203、第二设备接收第一设备发送的编码方式指示；
S204、所述第二设备根据所述编码方式指示，确定所述第一数据的编码方式和/或所述第二数据的编码方式。
本实施例的第一设备和第二设备可以为任意的具有通信功能的设备，例如终端设备、网络设备等等。第一设备与第二设备可以进行通信，第一设备与第二设备的通信方式可以为单向的也可以为双向的，本实施例对第一设备和第二设备的通信方式不做特别限制。
在一种可能的实现方式中，第一设备可以向第二设备发送第一数据，则第二设备接收第一设备发送的第一数据。此时，第一设备为编码侧，第二设备为译码侧，第一设备向第二设备发送编码方式指示，该编码方式指示可以指示第一数据的编码方式，第二设备可以根据该编码方式指示确定第一数据的编码方式。当第一设备向第二设备发送第一数据后，第二设备采用对应的译码方案对第一数据进行译码。
在另一种可能的实现方式中，第二设备可以向第一设备发送第二数据，此时，第一设备为译码侧，第二设备为编码侧。第一设备向第二设备发送编码方式指示，该编码方式指示可以指示第二数据的编码方式，第二设备根据该编码方式的指示确定对第二数据的编码方式，然后根据第二数据的编码方式对第二数据进行编码，将编码后的第二数据发送给第一设备，第一设备采用对应的译码方案对第二数据进行译码。
在又一种可能的实现方式中，第一设备可以向第二设备发送第一数据，第二设备还可以向第一设备发送第二数据，第一设备向第二设备发送编码方式指示，可以同时指示第一数据的编码方式和第二数据的编码方式。针对第一设备发送第一数据以及第二设备发送第二数据的实现方式，可参见上述的两种可能的实现方式，本实施例此处不再赘述。
在各种可能的实现方式中，该编码方式指示可以为动态的，即每次发送第一数据和/或第二数据时，第一设备都可以发送编码方式指示给第二设备；该编码方式指示也可以为半静态的，即第一设备向第二设备发送编码方式指示后，该指示在一段时间内有效，再没有发送新的编码方式指示时，将一直被使用。
该编码方式指示可以显式或隐式指示第一数据的编码方式和/或第二数据的编码方式。对于显式指示而言，第一设备可以向第二设备直接发送指示，也可以为第一设备向第二设备发送信息或信令，该信息或信令可以等同于编码方式指示，用于指示编码方式等。本实施例对编码方式指示的显式指示方式不做特别限制。
对于隐式指示而言，第一设备向第二设备发送信息、信令、索引、序列等，该信息、信令、索引以及序列等可以与编码方式指示具有映射关系或映射关系，可以等同于编码方式指示。该第二设备可以在接收到对应的信息、信令或索引等，根据该映射关系或映射关系，获取第一数据的编码方式和/或第二数据的编码方式。在本实施例中，第一设备向第二 设备发送的任何内容，都可以对第一数据的编码方式和/或第二数据的编码方式进行隐式指示。本实施例对隐式指示的方式不做特别限制。
本领域技术人员可以理解，由于译码方案与编码方式具有对应性，才能保证译码侧译码。由此，该编码方式指示也可以理解为编译码方案指示，即同时指示编码方式和译码方案。此时可以描述为第一设备向第二设备发送编译码方案指示，该编译码方案指示用于指示第一数据的编译码方案和第二数据的编译码方案。
在本实施例中，第一数据的编码方式可以为Polar编码方式或LDPC编码方式。第二数据的编码方式可以为Polar编码方式或LDPC编码方式。其中，Polar编码方式或LDPC编码方式的具体实现方式，可参见上述实施例，本实施例此处不再赘述。第一数据的编码方式还可以为其它编码方式，第二数据的编码方式还可以为其它编码方式，例如Turbo码编码方式等。
本申请实施例提供的编码方式指示，第一设备获取编码方式指示，编码方式指示用于指示第一数据的编码方式和/或第二数据的编码方式；第一数据为第一设备向第二设备发送的数据，第二数据为第二设备向第一设备发送的数据，第一设备向第二设备发送编码方式指示，实现了第二设备与第一设备收发端对齐编码方式，从而在各种混合编码情况下，接收端可以获知发送端发送的数据的编码方式，从而可以采用正确的译码方案进行译码。
由上述实施例的描述可知，第一设备和第二设备可以为具有通信功能的设备。下面本实施例给出一些可能的场景，对第一设备和第二设备的具体示例进行详细说明。本领域技术人员可以理解，下述的实施例不仅适用于本实施例所列出的场景，还适用于其它场景，本实施例对各种可能的场景不做特别限制，只要所实现的方法与本实施例类似，即为本申请的保护范畴。
在一种可能的实现方式中，本实施例可以应用到免调度系统中，其中，该第一设备可以为终端设备，第二设备可以为网络设备，该第一数据可以为第一设备向第二设备发送的上行数据。
其中，在免调度系统中，网络设备预先分配并告知终端设备多个传输资源；终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端设备发送的上行数据。所述检测可以是盲检测，也可能根据所述上行数据中某一个控制域进行检测，或者是其他方式进行检测。
即终端设备可以在无网络设备调度的情况下发起上行数据传输。因此终端设备需要将信道的编码方式通知给网络设备，以方便网络设备进行译码。在此种场景下，第一设备可以通过显式或隐式的方式指示上行数据的编码方式。下面结合图3至图7，给出可能的实现方式。
图3为本申请一实施例提供的编码方式的指示方法的信令流程图。如图3所示，该方法包括：
S301、第一设备根据导频序列组与编码方式的映射关系，获取第一数据的编码方式所对应的第一导频序列，第一导频序列所属的导频序列组用于指示第一数据的编码方式；
S302、第一设备向第二设备发送第一导频序列；
S303、第二设备接收第一设备发送的第一导频序列，并确定第一导频序列所属的导频 序列组；
S304、第二设备根据导频序列组与编码方式的映射关系，确定第一导频序列所属的导频序列组所指示的第一数据的编码方式。
在具体实现过程中，第一设备先确定第一数据的编码方式。第一设备可以根据信道质量、第一数据的业务类型以及第一设备的能力中的至少一种，确定第一数据的编码方式。信道质量是指第一设备与第二设备之间的信道好坏，业务类型比如是要求可靠度极高的业务，或者是要求吞吐较高可靠度不需要太高的业务。第一设备的能力可以为第一设备的软硬件能力，例如若第一设备为低成本设备，则可能对第一设备配备一种编译码器。第一设备可以根据上述的一种或两种或三种来确定第一数据的编码方式，本实施例对第一设备确定第一数据的编码方式的具体实现方式不做特别限制。
在得到第一数据的编码方式之后，获取第一数据的编码方式所对应的第一导频序列，该第一导频序列所属的导频序列组用于指示第一数据的编码方式。
具体地，导频序列，也称为导频信号，包括非零导频(non-zero pilot)和零导频(又称为空导频，null pilot)。导频序列常用于通信系统的信道估计和射频失真(Radio Frequency Distortion)补偿，在免调度通信系统中，导频序列被用于用户检测。
在本实施例中，将导频序列分为两个组，每组对应一种编码方式。图4为本申请一实施例提供的导频序列组与编码方式的映射关系的示意图。如图4所示，导频序列1至导频序列M属于Polar编码方式组，导频序列M+1至导频序列N，对应LDPC编码方式组。当第一设备确定第一数据的编码方式为Polar编码方式时，则从Polar编码方式组中即导频序列1至导频序列M中选择一个第一导频序列发送给第二设备。当第二设备确定第一数据的编码方式为LDPC编码方式时，则从LDPC编码方式组中即导频序列M+1至导频序列N中选择一个第一导频序列。
第一设备在选择得到第一导频序列后，第一设备可以向第二设备发送第一导频序列和第一数据(上行数据)，第二设备可以根据第一导频序列检测到第一设备，并根据第一导频序列所属的导频序列组，确定第一数据的编码方式，然后根据第一数据的编码方式对第一数据进行译码。
本领域技术人员可以理解，在具体实现过程中，还可以不对导频序列进行分组，存在导频序列与编码方式的映射关系即可。例如，第一设备根据导频序列与编码方式的映射关系，获取第一数据的编码方式所对应的第一导频序列，对应地，第二设备根据导频序列与编码方式的映射关系，来获取第一导频序列的所指示的第一数据的编码方式。
本申请实施例通过导频序列组与编码方式的映射关系，对编码方式进行隐式指示，不需要再单独发送编码方式指示，也不会对现有信息或信令等作出改变，即不需要对现有传输方式做出改变，使得第一设备向第二设备发送编码方式指示的过程简单易行，易于实现。
图5为本申请一实施例提供的编码方式的指示方法的信令流程图。如图5所示，该方法包括：
S501、第一设备根据导频序列映射的物理资源位置与编码方式的映射关系，获取第一数据的编码方式所对应的第二导频序列映射到的物理资源位置，第二导频序列映射到的物理资源位置用于指示第一数据的编码方式；
S502、第一设备在所述物理资源位置对应的物理资源上向第二设备发送第二导频序列；
S503、第二设备接收第一设备在物理资源上发送的第二导频序列；
S504、第二设备根据导频序列映射的物理资源位置与编码方式的映射关系，确定第二导频序列映射到的物理资源位置所指示的第一数据的编码方式。
本实施例与图3实施例不同的是，本实施例中的导频序列与编码方式没有映射关系，而是该导频序列映射的物理资源位置与编码方式具有映射关系。
例如，第一设备使用Polar编码方式时，将第二导频序列映射到对应Polar码的物理资源位置，使用LDPC编码方式时，则第二导频序列映射到对应LDPC码的物理资源位置。第二设备若在Polar码对应的物理资源位置上检测到第一设备发送的的第二导频序列，则使用Polar码译码该用户的数据，LDPC同理。
本实施例中的第二导频序列的含义和用途与图3实施例中的第一导频序列类似，本实施例此处不再赘述。
在具体实现过程中，该物理资源位置可以为第二导频序列映射在物理资源上的时域上的位置和/或频域上的位置。例如，可以对Polar码和LDPC码对应的第二导频序列映射的物理资源的时域位置进行限定，频域不做限定；再例如，还可以对Polar码和LDPC码对应的第二导频序列映射的物理资源的频域位置进行限定；再例如，还可以对Polar码和LDPC码对应的第二导频序列映射的物理资源的时域和频域位置进行限定。本实施例对第二导频序列映射在物理资源上的方式不做特别限定，只要第一设备和第二设备预先约定了相同的规则，能够识别出Polar编码方式和LDPC编码方式即可。
以一个例子为例，图6为本申请一实施例提供的物理资源位置与编码方式的映射关系的示意图。具体地，设导频序列为r(m)，它映射位置可以如下式计算：
a k,l＝r(m)，其中l为时域正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的索引(index)，k为子载波的索引，第一设备和第二设备约定，也可以由标准给出；
Figure PCTCN2019074507-appb-000004
其中，m为自然数。
若第二导频序列映射到的物理资源位置为频域上的偶数位，则编码方式指示用于指示LDPC编码方式，若第二导频序列映射到的物理资源位置为频域上的奇数位，则编码方式指示用于指示Polar编码方式。
如图6所示，在时域上的第一个符号，用于传输该第二导频序列，当在频域上的偶数位(从下往上数)传输第二导频序列时，则编码方式指示用于指示LDPC编码方式，当在频域上的奇数位(从下往上数)传输第二导频序列时，则编码方式指示用于指示Polar编码方式。
本领域技术人员可以理解，还可以在第二导频序列映射到的物理资源位置为频域上的偶数位，编码方式指示用于指示Polar编码方式，第二导频序列映射到的物理资源位置为频域上的奇数位，则编码方式指示用于指示LDPC编码方式。
本申请实施例通过导频序列映射的物理资源位置与编码方式的映射关系，对编码方式进行隐式指示，不需要再单独发送编码方式指示，也不会对现有信息或信令等作出改变，即不需要对现有传输方式做出改变，使得第一设备向第二设备发送编码方式指示的过程简单易行，易于实现。
在本申请实施例中，还可以使用导频序列和其映射的物理资源位置共同指示，例如考虑到免调度系统中存在多个用户以非正交接入方式共用物理资源的情况，为降低用户间的碰撞概率，可以使用导频序列和其映射的时频资源位置共同指示信道编码方式。
图7为本申请一实施例提供的编码方式的指示方法的信令流程图，如图7所示，该方法包括：
S701、第一设备获取第一索引，第一索引与编码方式具有映射关系，第一索引用于指示第一数据的编码方式；
S702、第一设备向第二设备发送第一索引；
S703、第二设备接收第一设备发送的第一索引；
S704、第二设备根据第一索引与编码方式的映射关系，获取第一索引指示的第一数据的编码方式。
在本实施例中，该第一索引可以为第一设备向第二设备发送的任意的索引。以一个具体的例子为例，该第一索引可以为信道质量指示(Channel Quality Indicator，CQI)索引。
其中，信道质量由第一设备测量所得，所以一般是指下行信道质量的好坏，和信道的信噪比大小相对应，信道质量的好坏可以量化为信道质量指示(Channel Quality Indicator，CQI)的索引来表征，CQI的索引取值范围0～15。CQI取值为0时，信道质量最差；CQI取值为15的时候，信道质量最好。第二设备可以根据CQI的大小确定传输数据块大小、信道码数的多少、编码方式、调制方式等。
第一设备在获取到第一索引之后，可直接将该第一索引发送给第二设备，由第二设备根据第一索引与编码方式的映射关系，获取第一索引指示的第一数据的编码方式。在一种可能的实现方式中，表一给出了一个映射表，该映射表示出了CQI索引与编码方式的映射关系。
表一
Figure PCTCN2019074507-appb-000005
其中，本文中表1所示的映射表也可以称作CQI表。其中，映射表包括CQI的索引与调制阶数、码率或频谱利用效率以及编码方式的映射关系。该映射表中任意一个CQI索引与调制阶数、码率或频谱利用效率以及编码方式之间满足表一中所示的映射关系。可选地，在具体实现过程中，该LDPC的编码方式还可以区分为BG1LDPC编码方式或BG2LDPC编码方式。
其中，调制阶数决定了1个符号中传输的比特数。例如，QPSK对应的调制阶数为2，16QAM的调制阶数为4，而64QAM的调制阶数为6。
码率为传输块中信息比特数与物理信道的总比特数之间的比值。
频谱利用效率表示一个资源单元(resource element，RE)所能承载的信息比特。
其中，频谱利用效率和码率可以互化，因此实际应用中，在表一中频谱利用效率和码率两列可能都出现，也可能只出现其中一列。根据表一，每个CQI对应一个索引，CQI索引为1～9时，数据信道使用Polar码编码方式，CQI索引为9～15时，数据信道使用LDPC码编码。第一设备根据信道条件等信息，获取CQI表中的一个索引，反馈给第二设备。第二设备通过收到的CQI索引，从映射表中得到第一设备希望使用的数据信道编码方式。当无其他指示信息时，则基站使用CQI索引对应的编码方式。
本领域技术人员可以理解，第一设备和第二设备均会预存该映射表，第一设备根据获取的调制阶数、码率或频率利用效率或编码方式从预存的映射表中选取CQI索引；第二设备根据该CQI索引，从预存的映射表中获取该CQI索引所对应的编码方式。
本申请实施例通过第一设备向第二设备发送第一索引，第二设备根据该第一索引获取第一数据的编码方式，即对编码方式进行隐式指示，不需要再单独发送编码方式指示，也不会对现有信息或信令等作出改变，即不需要对现有传输方式做出改变，使得第一设备向第二设备发送编码方式指示的过程简单易行，易于实现。
本领域技术人员可以理解，上述的图3至图7所示的实施例中，不仅可以应用到免调度系统，还可以应用到网络设备调度的系统中，其实现原理和技术效果类似，本实施例此处不再赘述。
在另一种可能的实现方式中，本实施例应用到网络设备调度终端设备的系统中，在该系统中，第一设备可以为网络设备，第二设备为终端设备，第一数据为下行数据，第二数据为上行数据。即网络设备来决定终端设备发送给网络设备的上行数据的编码方式，同时网络设备向终端设备发送下行数据的编码方式。在调度系统中，终端设备向网络设备发送上行数据或网络设备向终端设备发送下行数据，都需要网络设备进行调度，该调度可以为资源的调度，编码方式的调度等等。
在具体实现过程中，第一设备生成信息，该信息用于指示第一数据的编码方式和/或用于指示第二数据的编码方式；第一设备向第二设备发送该信息，第二设备接收该信息，根据该信息获取第一数据的编码方式和/或用于指示第二数据的编码方式。
第一设备先确定第一数据和/或第二数据的编码方式，然后生成信息。该第一设备可以根据信道质量、第一数据的业务类型以及第二设备的能力中的至少一种，确定第一数据的编码方式；和/或，第一设备根据信道质量、第二数据的业务类型以及第二设备的能力中的至少一种，确定第二数据的编码方式。对于具体的实现方式，可参见上述实施例，本实施例此处不再赘述。
本实施例中的信息，可以广义的理解为信息、信令、消息等。本领域技术人员可以理解，该信息可以为控制面的信息，也可以为数据面的信息，对于控制面的信息，也可以称为信令。针对第一设备向第二设备发送信息的方式，也适用于第一设备为终端设备，第二设备为网络设备。
下面结合图8至图10，对调度系统中的编码方式的指示方法进行详细说明。即第一设备为网络设备，第二设备为终端设备。其中上述的信息可以为各种类型的信息，本实施例对信息的类型不做特别限制，此处给出一些示意。本领域技术人员可以理解，下述的图8至图10，不仅可以应用到调度系统中，还可以应用到其它系统中，本实施例此处不再赘述。
图8为本申请一实施例提供的编码方式的指示方法的信令流程图，如图8所示，该方法包括：
S801、第一设备生成RRC信令，该RRC信令中包括第一信道配置字段和/或第二信道配置字段，所述第一信道配置字段中的编码方式类型字段用于指示第一数据的编码方式；所述第二信道配置字段中的编码方式类型字段用于指示第二数据的编码方式；
S802、第一设备向第二设备发送RRC信令；
S803、第二设备接收第一设备发送的RRC信令；
S804、第二设备根据所述第二信令，确定所述第一数据的编码方式和/或所述第二数据的编码方式。
在本实施例中，上述的消息可以为无线资源控制(Radio Resource Control，RRC)信令，该RRC信令可以为系统信息等。在本实施例中以系统信息为例进行说明。该系统信息可以分为主信息块和系统信息块。可以在主信息块中携带编码方式指示，也可以在系统信息块中携带编码方式指示，本实施例此处不做特别限制。
在一个具体的实施例中，在系统信息块中携带第一信道配置字段和/或第二信道配置字段。该第一信道配置字段中的编码方式类型字段用于指示第一数据的编码方式；该第二信道配置字段中的编码方式类型字段用于指示第二数据的编码方式。第一设备可以指示第一数据的编码方式，或者指示第二数据的编码方式，还可以同时指示第一数据的编码方式和第二数据的编码方式。可选地，当系统信息块为多个时，可在一个系统信息块中携带第一信道配置字段和/或第二信道配置字段，也可以在不同的系统信息块中分别携带第一信道配置字段和第二信道配置字段。
具体地，当第一数据为上行数据时，该第一信道配置字段可以为物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)配置字段，可以为PDSCH-Config字段。该PDSCH-Config中可以增加信道的编码方式类型字段(channel Coding Type)用于指示下行数据的信道的编码方式类型。Channe lCoding Type可以是BOOLEAN类型的，用‘true’和‘false’区分Polar和LDPC，也可以是其他类型，例如整数(INTEGER)，用‘0’或‘1’区分Polar和LDPC；列举或枚举(ENUMERATED)，用‘Polar’和‘LDPC’直接指示编码方式为Polar或LDPC。
可选地，该PDSCH-Config字段还可以包括码块组传输(code Block Group Transmission)字段，用于指示是否使用基于码块组(CBG)的传输，码块组的最大数量(maxCodeBlockGroupsPerTransportBlock)用于指示每个传输块(TB)最多包含码块组的数量。PDSCH-Config还包含对解调参考信号(dmrs)、传输配置指示(Transmission  configuration Indicator,TCI)等参数的配置参数，在此不一一赘述。
当第二数据为下行数据时，该第二信道配置字段可以为物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)配置字段，可以为PUSCH-Config字段。同理，可以在PUSCH-Config里增加信道的编码方式类型字段(channel Coding Type)用于指示上行数据的信道的编码方式类型。PUSCH-Config字段中的channel Coding Type实现方式与PDSCH-Config字段中的channel Coding Type字段的实现方式类似，本实施例此处不再赘述。对于PUSCH-Config字段中的其它字段，本实施例此处不再赘述。
第一设备可以生成系统信息块，并发送给第二设备，第二设备根据该系统信息块中的第一信道配置字段和/或第二信道配置字段中的编码方式类型指示字段，来确定第一数据和/或第二数据的编码方式。
本申请实施例通过在RRC信令来实现编码方式的指示，由于RRC信令贯穿第一设备与第二设备的整个通信过程，因此通过RRC信令不需要增加新的信息，在易于实现的基础上发送编码方式指示，使得收发两端可以对齐编码方式。
图9为本申请一实施例提供的编码方式的指示方法的信令流程图，如图9所示，该方法包括：
S901、第一设备生成下行控制信息DCI，该DCI用于调度第一数据，该DCI用于指示第一数据的编码方式，或者，该DCI用于调度第二数据，该DCI用于指示第二数据的编码方式；
S902、第一设备向第二设备发送DCI；
S903、第二设备接收第一设备发送的DCI；
S904、第二设备根据DCI，确定第一数据的编码方式或第二数据的编码方式。
在具体实现过程中，下行控制信息(Downlink Control Information，DCI)可以显式指示编码方式，也可以隐式指示编码方式，下面分别进行说明。其中，该DCI可以用于上行数据的调度或下行数据的调度，包括资源分配以及其他控制信息等。
在DCI显式指示编码方式时，可在DCI中增加编码方式类型字段以用于指示第一数据的编码方式或第二数据的编码方式。
图10为本申请一实施例提供的DCI的结构示意图。如图10所示，在DCI中增加编码方式类型字段，该编码方式类型字段例如可以通过整数(INTEGER)的方式，用‘0’或‘1’区分Polar和LDPC。
本领域技术人员可以理解，当该信息用于调度第一数据市，则该信息中的编码方式类型字段用于指示第一数据的编码方式；或者，当该信息用于调度第二数据时，该信息中的编码方式类型字段用于指示第二数据的编码方式。即当DCI调度上行数据时，则DCI中的编码方式类型字段用于指示上行数据的编码方式，或者，当DCI调度下行数据时，则DCI中的编码方式类型字段用于指示下行数据的编码方式，以保证与DCI的调度保持一致性。
可选地，在该DCI中还可以包括Header(包头)、Carrier indicator(载波指示)、BWP indicator(带宽部分指示)、F resources(频域资源位置)、T resources(时域资源位置)、MCS index(调制编码方式索引)、RV version(冗余版本)、NDI(新数据指示)等字段。
在DCI隐式指示编码方式时，可以通过在DCI中携带第二索引来隐式指示编码方式。该第二索引可以为任意的携带在DCI中的索引。在一种可能的实现方式中，可以通过上述 的DCI字段中的调制编码方式(Modulation and Coding Scheme，MCS)索引进行隐式指示。
具体地，在一个可能的通信系统中，物理共享信道可以分为上行物理信道和下行物理信道，上行和下行均支持四相相移键控(Quadri Phase Shift Key，QPSK)，16正交振幅调制(16Quadrature Amplitude Modulation，16QAM)，64QAM等多种调制方式。调制方式对应的其星座图，依次需要的信道条件也不相同，简单的来说，调制方式越高(QPSK<16QAM<64QAM)，依赖的信道条件需要越好。
不同的调制方式以及调制阶数，对应的编码方式不同，每种调制阶数、调制阶数以及编码方式等，可以用MCS索引来指示。表二给出了一个映射表，该映射表示出了MCS索引与编码方式的映射关系。
表二
Figure PCTCN2019074507-appb-000006
其中，本文中表二所示的映射表也可以称为MCS表。其中，映射表包括MCS的索引与调制阶数、码率或频谱利用效率以及编码方式的映射关系。该映射表中任意一个MCS索引与调制阶数、码率或频谱利用效率以及编码方式之间满足表二中所示的映射关系。
其中，调制阶数、码率或频谱利用效率或编码方式的具体含义，可参见表一所示，本实施例此处不再赘述。
第一设备和第二设备均预存有该映射表，第一设备获取第二索引，该第二索引与编码方式具有映射关系，第一设备根据第二索引生成该信息，该信息中包括第二索引，所述第二索引用于指示第一数据的编码方式或第二数据的编码方式。该第二索引可以为上述的MCS索引。
具体地，网络设备可以确定上行数据或下行数据的调制阶数和编码方式，然后根据已经确定的调制阶数和编码方式，根据该预存的映射表所示的内容来确定MCS索引。对于网络设备确定调制阶数和编码方式的具体实施方式，本实施例此处不做特别限制。在具体应用过程中，MCS索引与编码方式的映射关系可以通过表来实现，也可以通过其它方式来实现。在通过表二实现时，可以为表二中包括MCS索引与编码方式的两列或几列，本实施例对表二的实现方式不做特别限制。
在网络设备确定MCS索引之后，生成包含该MCS索引的DCI，网络设备向终端设备发送该DCI，以通过DCI将该MCS索引发送给终端设备，终端设备通过该MCS索引查询预存的映射表(表2)，就可以得到信道的编码方式。
本领域技术人员可以理解，在该信息为DCI时，若该DCI用于调度第一数据(上行数据)，则该DCI中的第二索引用于指示第一数据的编码方式；或者，若该DCI用于调度第 二数据(下行数据)，则该DCI中的第二索引用于指示第二数据的编码方式。
本申请实施例通过DCI来显式或隐式指示编码方式，不需要通过其它的信息，通过现有的信息就可以是实现编码方式的指示，使得收发两端可以对其编码方式。
在上述实施例的基础上，对于终端设备来指示终端设备向网络设备发送的上行数据的编码方式的示例中，网络设备还可以不采用终端设备指示的编码方式，而是重新向终端设备指示编码方式。下面结合图11进行详细说明。
图11为本申请一实施例提供的编码方式的指示方法的信令流程图，如图11所示，该方法包括：
S1101、第二设备向第一设备发送第三索引；
S1102、第一设备接收第二设备发送的第三索引，并根据第三索引与编码方式的映射关系，获取第三索引所指示的第一数据的编码方式；
S1103、第一设备判断第三索引所指示的第一数据的编码方式与第一设备确定的第一数据的编码方式是否一致，若是，则第一设备根据第三索引所指示的第一数据的编码方式，生成所述编码方式指示；若否，则第一设备根据第一设备确定的第一数据的编码方式，生成编码方式指示；
S1104、第一设备向第二设备发送用于指示第一数据的编码方式的编码方式指示。
在本实施例中，该第三索引可以为第二设备向第一设备发送的任意的索引。在一种可能的实现方式中，第一设备为网络设备，第二设备为终端设备，第三索引为CQI索引。具体地，第二设备接收第一设备发送的CQI索引，第一设备接收该CQI索引，第一设备根据该CQI索引来查表一，可以获取第一数据的编码方式，该编码方式为第二设备希望的编码方式。
该CQI索引不仅与编码方式具有映射关系，该CQI索引还可以指示信道质量，由上论述可知，网络设备可以根据信道质量、第一数据的业务类型以及第一设备的能力中的至少一种，确定第一数据的编码方式。由此，网络设备可以根据该CQI或者结合其它信息，来确定信道的编码方式。
若第三索引所指示的第一数据的编码方式与网络设备确定的第一数据的编码方式一致，则网络设备根据第三索引所指示的第一数据的编码方式，生成编码方式指示，该编码方式指示的第一数据的编码方式与第三索引所指示的第一数据的编码方式一致。
若第三索引所指示的第一数据的编码方式与网络设备确定的第一数据的编码方式不一致，则网络设备根据网络设备确定的第一数据的编码方式，生成编码方式指示，该编码方式指示的第一数据的编码方式与网络设备确定的第一数据的编码方式一致。
网络设备在生成编码方式指示之后，可通过上述的图8至图10所示的方式，例如RRC信令、DCI等方式将该编码方式指示发送给终端设备。
本申请实施例通过第一设备综合考虑第一数据的编码方式，使得第一数据的编码方式更适合信道传输，同时满足业务的传输需求等。
