Description

一种信息的编码方法及设备 技术领域
本申请涉及通信技术领域，尤其涉及一种信息的编码方法及设备。
背景技术
系统消息是小区级别的控制信息，终端(例如，手机和电脑等)只有在获取系统消息之后，才能成功接入小区，得以正确的工作。系统消息可以包括三种类型，分别为主信息块(英文：master information block，简称：MIB)、系统信息块1(英文：system information block 1，简称：SIB1)和系统信息(英文：system information，简称：SI)。现有的系统消息的结构示意图可如图1所示。
如图1所示，MIB包括有限个用以读取小区信息的最重要、最常用的传输参数。例如，传输参数可包括系统带宽、系统帧号和物理混合自动重传指示信道(英文：physical hybrid arq indicator channel，简称：PHICH)配置信息等参数。图2是现有的信道映射的示意图。如图2所示，网络设备(如基站)通过广播控制信道(英文：broadcast control channel，简称：BCCH)传递MIB至广播信道(英文：broadcast channel，简称：BCH)，再通过BCH传递MIB至物理广播信道(英文：physical broadcast channel，简称：PBCH)，并在PBCH对MIB进行编码。相应地，终端设备(如手机)在接收MIB之后对MIB进行译码。
如图1所示，SIB1携带所有SI的调度信息以及小区接入的相关信息。SI中包括除SIB1之外的SIB，例如，SI中可包括SIB2、SIB3和SIB4等。如图2所示，网络设备通过BCCH传递SIB1(或SI)至下行共享信道(英文：downlink-shared channel，简称：DL-SCH)，再通过DL-SCH传递SIB1(或SI)至物理下行共享信道(英文：physical downlink shared channel，简称：PDSCH)，并在PDSCH对SIB1(或SI)进行编码。相应地，终端设备在接收SIB1(或SI)之后，对SIB1(或SI)进行译码。
在第五代(英文：5th Generation，简称：5G)通信系统以及后续更多可能的通信系统中定义了三大类场景，分别为增强移动宽带(英文：enhanced Mobile Broadband，简称：eMBB)、超可靠低延时通信(英文：Ultra Reliable Low Latency Communications，简称：URLLC)和大规模物联网通信(英文：massive Machine Type Communications，缩写：mMTC)。其中，eMBB业务主要包含超高清视频、增强现实AR、虚拟现实VR等等，主要特点是传输数据量大、传输速率很高。URLLC业务主要是用于物联网中的工业控制、无人驾驶等，主要特点是超高可靠性、低延时，传输数据量较少以及具有突发性。mMTC业务主要是用于物联网中的智能电网、智慧城市等，主要特点是海量设备连接、传输数据量小、容忍较长时间的延时。
不同的通信场景可能需要不同的编码译码方式。在灵活地选择一种编码方式对系统消息进行编码之后，如何灵活地对系统消息进行译码是目前亟待解决的问题。

具体实施方式
下面结合附图对本申请具体实施例作进一步的详细描述。
在第五代(英文：5th Generation，简称：5G)通信系统以及后续更多可能的通信系统中具有多种通信场景，如eMBB、URLLC和mMTC。不同的通信场景可能需要不同的编码译码方式。然而在网络设备(如基站)根据不同的通信场景灵活地选择一种编码方式对系统消息进行编码之后，移动设备(如手机)并不知道需要采用哪一种译码方式进行译码。因此，在网络设备根据不同的通信场景灵活地选择一种编码方式对系统消息进行编码之后，移动设备并不能灵活地采用正确的译码方式进行译码。
为了使移动设备能够灵活地对系统消息进行译码，即为了使移动设备能够选择正确的译码方式进行译码，本申请实施例提供了一种信息的编码方法及设备。
本申请实施例可以应用于无线通信系统，无线通信系统通常由小区组成，每个小区包含一个基站(英文：Base Station，简称：BS)，基站向多个移动台(英文：Mobile Station，简称：MS)提供通信服务，其中基站连接到核心网设备，如图3所示。本申请实施例所涉及的网络设备可以为图3中的基站，或者基带处理单元(英文：Baseband Unit，简称：BBU)，本申请实施例所涉及的移动设备可以为图3中的移动台。

为便于对本申请实施例进行理解，下面对现有的系统消息的获取过程进行介绍。
图4为现有的系统消息的获取过程示意图，如图4所示，终端设备(如手机)接收MIB之后，根据MIB获取物理下行控制信道(PDCCH)的特定下行控制信息(英文：Downlink Control Information，缩写：DCI)；终端设备获取DCI信息之后，根据DCI信息中SIB1的调度信息，在PDSCH中获取SIB1。终端获取SIB1之后，再根据SIB1中SI的调度信息，在PDSCH中获取SI。
下面进一步对本申请所提供的信息的编码方法和设备进行介绍。
请参见图5，图5是本申请实施例提供的一种信息的编码方法。如图5所示，该信息的编码方法包括如下501和502部分：
501、网络设备对MIB进行编码。
该MIB包括指示信息，该指示信息用于终端设备确定对第一信息进行译码的译码方式，该第一信息包括SIB1和SI中的至少一种。
502、网络设备发送编码后的MIB至终端设备。
503、终端设备对编码后的MIB进行译码，得到MIB中的指示信息。
终端设备接收MIB之后，可对MIB进行译码，得到MIB中的指示信息。
504、终端设备根据指示信息确定第一信息的译码方式。
终端设备对MIB译码后得到指示信息之后，根据指示信息确定第一信息的译码方式。
505、终端设备接收网络设备发送的编码后的第一信息。
终端设备在接收编码后的MIB之后，接收编码后的第一信息。
506、终端设备根据确定的译码方式对第一信息进行译码。
终端设备接收编码后的第一信息之后，根据确定的译码方式对第一信息进行译码。
例如，polar码编码包括校验辅助polar码(即PC-polar码)编码和循环冗余校验辅助polar码(即CA-polar码)编码。使用PC-polar码编码，则需使用校验辅助串行抵消列表(英文：parity-check successive cancellation list，简称：PC-SCL)译码；使用CA-polar码编码，则需使用循环冗余校验辅助串行抵消列表(英文：crc aided successive cancellation list，简称：CA-SCL)译码。因此，若第一信息为SIB1和SI，网络设备使用PC-polar码对SIB1和SI进行编码，则终端设备根据指示信息可确定对SIB1和SI进行译码的译码方式为PC-SCL译码；网络设备使用CA-polar码对SIB1和SI进行编码，则终端设备根据指示信息可确定对SIB1和SI进行译码的译码方式为CA-SCL译码。
再如，若第一信息为SIB1和SI，网络设备使用低密度奇偶校验(英文：Low-density Parity-check，简称：LDPC)码对SIB1和SI进行编码，则终端设备根据指示信息可确定对SIB1和SI进行译码的译码方式为LDPC码对应的译码方式，例如，LDPC码对应的译码方式可包括分层归一化最小和(英文：layered normalized min-sum，简称：LNMS)译码和分 层偏移最小和(英文：layered offset min-sum，简称：LOMS)译码等。
通过实施图5所描述的方法，网络设备可对包括指示信息(用于终端设备确定对第一信息进行译码的译码方式)的MIB进行编码，并发送编码后的MIB至终端设备。从而终端设备可在接收SIB和SI之前，就可根据指示信息确定SIB和SI正确的译码方式，进而在终端设备接收SIB和SI之后就可使用正确的译码方式进行译码。可见，通过实施图5所描述的方法，有利于终端设备灵活地对SIB和SI进行译码。
作为一种可选的实施方式，MIB包括的指示信息包括第一指示信息，该第一指示信息用于指示第一信息采用的编码方式。例如，该编码方式可以为polar码编码方式或LDPC码编码方式等，本申请实施例不做限定。
在该实施方式中，可选的，终端设备可预先设置polar码编码方式对应的一种译码方式(例如为PC-SCL译码)和LDPC码编码方式对应的一种译码方式(例如为LNMS译码)。可选的，第一指示信息可以为1比特的二进制，例如，可以使二进制0表示polar码编码方式，二进制1表示LDPC码编码方式。终端设备译码得到第一指示信息之后，若第一指示信息为0，则终端设备使用PC-SCL译码方式对第一信息进行译码；若第一指示信息为1，则终端设备使用LNMS译码方式对第一信息进行译码。
通过实施该实施方式，可使终端设备根据第一指示信息成功确定对第一信息进行译码的译码方式。
作为一种可选的实施方式，MIB包括的指示信息包括第二指示信息，该第二指示信息用于指示对第一信息进行译码的译码方式。例如，网络设备使用polar码编码方式对第一信息进行编码，终端设备需要使用PC-SCL译码方式才能正确地译码，则第二指示信息用于指示对第一信息进行译码的译码方式为PC-SCL译码方式。同理，第二指示信息可以用二进制表示，例如，二进制00表示PC-SCL译码方式，二进制01表示CA-SCL译码方式，二进制10表示LNMS译码方式，二进制11表示LOMS译码方式。
通过实施该实施方式，可使终端设备根据第二指示信息成功确定对第一信息进行译码的译码方式。
作为一种可选的实施方式，MIB包括的指示信息也可同时包括第一指示信息和第二指示信息。例如，如下表1所示，第一指示信息为二进制0表示polar码编码方式，第一指示信息为二进制1表示LDPC码编码方式。当第一指示信息为0，第二指示信息为二进制0，则表示PC-SCL译码方式，第二指示信息为二进制1，则表示CA-SCL译码方式；当第一指示信息为1，第二指示信息为二进制0，则表示LNMS译码方式，第二指示信息为二进制1，则表示LOMS译码方式。

通过实施该实施方式，可使终端设备根据第三指示信息提高对第一信息进行译码的成功率。

请参见图6，图6是本申请实施例提供的另一种信息的编码方法。如图6所示，该信息的编码方法包括如下601和602部分：
601、网络设备对DCI进行编码。

再如，若第一信息为SIB1和SI，网络设备使用LDPC码对SIB1和SI进行编码，则终端设备根据指示信息可确定对SIB1和SI进行译码的译码方式为LDPC码对应的译码方式，例如，LDPC码对应的译码方式可包括LNMS译码和LOMS译码等。
通过实施图6所描述的方法，网络设备可对包括指示信息(用于终端设备确定对第一信息进行译码的译码方式)的DCI进行编码，并发送编码后的DCI至终端设备。从而终端设备可在接收SIB和SI之前，就可根据指示信息确定SIB和SI正确的译码方式，进而在终端设备接收SIB和SI之后就可使用正确的译码方式进行译码。可见，通过实施图6所描述的方法，有利于终端设备灵活地对SIB和SI进行译码。
