Description

一种信道编码指示方法、装置、系统及存储介质 技术领域
本发明涉及无线通信领域，尤其涉及一种信道编码指示方法、装置、系统及存储介质。
背景技术
现有标准中，扩展CP(循环前缀，Cyclic Prefix)下的联合编码比正常CP下的单独编码抗干扰能力强。对于PUCCH(物理上行链路控制信道，Physical Uplink Control CHannel)format2可以使用正常CP或扩展的CP，但对于PUCCH format 2a/2b，只能使用正常CP。PUCCH format 2的终端可以选择正常CP或扩展CP，支持正常CP时，仅上报CSI信息，而不上报ACK/NACK信息，而ACK/NACK信息却很重要，但是如果携带ACK/NACK信息，只能支持扩展CP。而PUCCH format2a/2b情况下，终端只能支持正常CP。但是当前只有扩展CP才能采用信道联合编码方法。那么，对于PUCCH format2a/2b终端，无法频繁在正常CP和扩展CP之间变换，而网络侧小区只能同时配置成正常CP或扩展CP，如果小区要变换CP，则基站必须重启，在现网环境下不可行。导致当仅支持正常CP的PUCCH format2a/2b终端处于高速运动环境时，抗干扰能力和抗多普勒能力差。也就是说，如果终端在高速运动下，但配置的PUCCH格式是format 2a/2b，抗干扰能力差，在高速运动情况下终端用户的用户体验会比较差，尤其是当小区内既有高速终端，也有低速终端时，很难通过配置CP模式来兼顾两者。

具体实施方式
下面将参照附图更详细地描述本发明的示例性实施例。虽然附图中显示了本发明的示例性实施例，然而应当理解，可以以各种形式实现本发明而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本发明，并且能够将本发明的范围完整的传达给本领域的技术人员。
实施例一
如图1所示，本发明的实施例提供了一种信道编码指示方法，应用于用户终端，具体包括以下步骤：
步骤101：当获取到的用于表征当前传输信道质量的参数信息满足预设条件时，生成测量信息。
其中，这里所说的参数信息包括各种能够直接或间接表征传输信道质量的参数，例如用户终端的移动速度、频移速度等。在步骤201之前，该方法还包括：接收当前接入服务小区的基站下发的配置信息，根据该配置信息检测该基站是否支持单独编码方式和联合编码方式，若支持，则获取用于表征当前传输信道质量的参数信息。
具体地，配置信息中携带有用于指示基站所支持的编码方式的信息。这里是说，当基站同时支持单独编码方式和联合编码方式两种编码方式时，用户终端才会获取表征传输信道质量的参数信息，若基站仅支持某一种编码方式时，用户终端则不会获取表征传输信道质量的参数信息。
进一步地，参数信息可包含多种参数，下面以移动速度、多普勒频移为例进行说明。当获取到的用于表征当前传输信道质量的参数信息满足预设条件时，生成测量信息具体包括以下几种场景。
场景一：检测获取到的自身移动速度是否超过第一速度阈值；若超过，则生成第一测量信息。
场景二：检测获取到的自身移动速度是否低于第二速度阈值；若低于，则生成第二测量信息。其中，第一速度阈值高于第二速度阈值；
其中，第一速度阈值和第二速度阈值分别为基站侧设置的速度高阈值Vx和速度低阈值Vy，基站在向用户终端发送配置信息时，将速度阈值信息承载至其中进行发送。当用户终端检测到自身的移动速度高于Vx，则说明当前抗干扰能力较差需要改变编码方式，这时触发生成第一测量信息并上报至基站。当用户终端检测到自身的移动速度低于Vy，则说明当前抗干扰能力较强，这时触发生成第二测量信息并上报至基站。
场景三：检测获取到的多普勒频移是否超过第一频移阈值；若超过，则生成第三测量信息。
场景四：检测获取到的多普勒频移是否低于第二频移阈值；若低于，则生成第四测量信息。其中，第二频移阈值低于第一频移阈值。
与场景一和场景二类似，第一频移阈值和第二频移阈值分别为基站侧 设置的多普勒频移高阈值Fx和频移低阈值Fy，基站在向用户终端发送配置信息时，将多普勒频移阈值信息承载至其中进行发送。当用户终端检测到自身的多普勒频移高于Fx，则说明当前抗干扰能力和抗多普勒频移能力较差需要改变编码方式，这时触发生成第三测量信息并上报至基站。当用户终端检测到自身的多普勒频移低于Fy，则说明当前抗干扰能力和抗多普勒频移较强，这时触发生成第四测量信息并上报至基站。
步骤102：将生成的测量信息上报给当前接入服务小区的基站。
用户终端可通过特定的上行消息上报生成的测量信息，优选地可将该测量信息承载至测量报告中进行上报。
步骤103：接收基站根据测量信息确定的指示信息。
其中，该指示信息用于指示用户终端采用与参数信息所对应的信道编码方式进行编码。基站在接收到用户终端上报的测量信息后，根据该测量信息获知当前传输信道质量，以确定当前用户终端所需要的编码方式，以保证用户终端的抗干扰性和抗多普勒频移能力。具体地，针对于场景一，用户终端接收基站根据第一测量信息确定的、用于指示用户终端采用联合编码方式进行编码的第一指示信息。针对于场景二，用户终端接收基站根据第二测量信息确定的、用于指示用户终端采用单独编码方式进行编码的第二指示信息。针对于场景三，用户终端接收基站根据第三测量信息确定的、用于指示用户终端采用联合编码方式进行编码的第三指示信息。针对于场景四，用户终端接收基站根据第四测量信息确定的、用于指示用户终端采用单独编码方式进行编码的第四指示信息。
步骤104：采用指示信息中的信道编码方式对物理上行控制信道PUCCH进行编码。
用户终端在接收到基站下发的指示信息后，采用指示信息中指示的信道编码方式对PUCCH进行编码，以提高自身的抗干扰能力和抗多普勒频移能力，保证传输质量，提高用户体验。
进一步地，在采用联合编码方式对PUCCH进行编码时，采用联合编码方式对信道状态信息CSI和应答信息ACK/NACK进行编码，得到对应的编码比特；将编码得到的编码比特映射至物理上行控制信道PUCCH中除参考 信号RS外的其他传输资源中传输至基站。具体地，用户终端将ACK/NACK反馈和CSI采用(20，A)联合编码，放置到非RS所在的符号上，并且放置在PUCCH上发送给基站，以使基站通过两个RS符号对于信道质量进行评估，并且进行(20，A)的解码。恢复出ACK/NACK和CSI信息。

依据本发明实施例的再一个方面，还提供了一种用户终端，包括如上所述的信道编码指示装置。
实施例三
以上实施例一和实施例二就用户终端侧对本发明的信道编码指示方法、装置和用户终端进行了介绍说明，下面本实施例将结合附图和具体应用场景对基站侧的信道编码指示方法作进一步介绍。
如图3所示，本发明实施例的信道编码指示方法，应用于基站侧，具体包括以下步骤：
步骤301：获取当前服务小区内的用户终端上报的测量信息。
其中，该测量信息为用户终端在获取到的用于表征当前传输信道质量的参数信息满足预设条件时生成的。
具体地，在步骤301之前该方法还包括向当前服务小区内的用户终端发送配置信息，以使用户终端根据该配置信息，检测基站是否支持单独编码方式和联合编码方式。其中，配置信息中携带有用于指示所述基站所支持编码方式的信息。也就是说当基站至少支持单独编码和联合编码方式两种编码方式时，用户终端才获取表征当前传输信道质量的参数信息，否则不获取。
步骤302：根据该测量信息向用户终端发送指示信息，以指示用户终端采用与参数信息所对应的信道编码方式进行编码。
其中，不同的测量信息所表征的传输信道质量不同，当测量信息为表征用户终端的移动速度超过第一速度阈值的第一测量信息时，向用户终端发送用于指示用户终端采用联合编码方式进行编码的第一指示信息。当测量信息为表征用户终端的移动速度低于第二速度阈值的第二测量信息时，向用户终端发送的用于指示用户终端采用单独编码方式进行编码的第二指示信息。其中，第一速度阈值高于第二速度阈值。
又或者，当测量信息为表征用户终端的多普勒频移超过第一频移阈值的第三测量信息时，向用户终端发送用于指示用户终端采用联合编码方式进行编码的第三指示信息。当测量信息为表征用户终端的多普勒频移低于第二频移阈值的第四测量信息时，向用户终端发送的用于指示用户终端采用单独编码方式进行编码的第四指示信息。其中，第二频移阈值低于第一频移阈值。
在步骤302之后，该方法还包括：当指示信息用于指示用户终端采用联合编码方式进行编码时，接收该用户终端采用联合编码方式、对信道状态信息CSI和应答信息ACK/NACK进行编码得到对应的编码比特。其中，该编码比特是映射至所述物理上行控制信道PUCCH中除参考信号RS外的其他传输资源中进行传输的。
下面结合基站和用户终端之间的交互过程，对本发明的信道编码指示方法做进一步说明。
基站通过特定的方式(例如广播消息)告知所服务的用户终端是否支持增强型信道编码方法(例如Speed Depend PUCCH2a2b)及其相关阈值的配置。当用户终端监听到基站支持Speed Depend PUCCH2a2b之后，周期性检测自己的速度变化或者多普勒频移变化。当测量到的速度或者频移超出基站配置的阈值之后，用户终端通过特定的上行消息(例如测量报告)上报自己的移动速度或者多普勒频移状态。基站接收到对应测量报告之后，经过判断评估之后，决定是否启用Speed Depend PUCCH2a2b功能。
当基站决定启用Speed Depend PUCCH2a2b之后，网络通过特定的下行消息告知终端启动Speed Depend PUCCH2a2b编码方案。
用户终端将ACK/NACK反馈和CSI采用(20，A)联合编码，放置到非RS所在的符号上，并且放置在PUCCH上发送给基站。基站通过两个RS符号对于信道质量进行评估，并且进行(20，A)的解码，恢复出ACK/NACK和CSI信息。
用户终端周期性的对于自己的运动状态进行评估，当发现自己的速度或者频移等指标低于网络配置的阈值之后，发送上行测量信息给基站。基站获知到终端的状态之后，通过评估后决定是否停止Speed Depend  PUCCH2a2b。
当基站停用Speed Depend PUCCH2a2b之后，通过特定的下行消息告知用户终端停用Speed Depend PUCCH2a2b编码方案。
用户终端获知停用Speed Depend PUCCH2a2b消息之后，后续的上行反馈采用3GPP中默认的标准方案进行编码和上报。
具体如图4所示，该信道编码指示方法包括：
步骤401：在基站侧配置增强型编码方案(Speed Depend PUCCH2a2b)参数并发给用户终端。其中，配置内容包括移动速度或多普勒频移的高阈值及低阈值。
步骤402:用户终端测量自己的移动速度或多普勒频移是否满足阈值条件，并上报测量报告给小区。
步骤403：基站根据终端上报的移动速度或多普勒频移判断，是否在小区和终端之间是否需要采用增强型编码方案。
步骤404：基站启动增强型编解码或单独编解码方案。
如图5所示，以下是一个具体的例子说明PUCCH format 2a/2b终端在高速度情况下灵活采用不同信道编码方法。
基站配置一个带有增强型编码方案参数(Speed Depend PUCCH2a2b参数)的配置消息下发给用户终端，告知终端本网络支持Speed Depend PUCCH2a2b，并在Speed Depend PUCCH2a2b中，配置速度阈值或多普勒频移阈值，比如配置移动速度高阈值为Vx，移动速度低阈值为Vy，多普勒频移高阈值为Fx，多普勒频移低阈值为Fy。
用户终端在接收到基站下发的带有Speed Depend PUCCH2a2b的消息后，检测自己的移动速度或多普勒频移，当自身的移动速度超过速度阈值Vx或多普勒频移超过多普勒频移高阈值Fx，则触发事件报告，该事件报告在此设定为C1，终端上报自己的移动速度或多普勒频移给基站。
当基站接收到用户终端上报的C1事件后进行判决，认为有必要启动针对ACK/NACK和CSI联合编码功能，然后通知用户终端启动联合编码，用户终端在接收到通知消息后，将ACK/NACK和CSI进行联合编码，上报联合编码给基站，基站收到联合编码，采用联合解码进行解码，联合编码采 用现有技术(20，A)编码方法，b0，b1，b2，b3，...，bB-1whereB＝20，
Figure PCTCN2016107155-appb-000001
其中，详细编码方法可参考3GPP TS36.212的5.2.3节，把ACK/NACK和CSI进行联合编码后，得到的20比特信息分散到除加载参考信号外的其他符号上进行传输。
用户终端周期性检测自己的速度和多普勒频移，如果自己的移动速度低于阈值Vy或多普勒频移低于阈值Fy，则触发事件报告C2并上报给基站，基站收到事件报告C2后，通知用户终端停止联合编码，然后用户终端开始使用ACK/NACK和CSI单独编码并上报给基站，基站使用单独解码进行解码。
用户终端配置为PUCCH format 2a/2b时，能够根据自身的移动速度或多普勒频移，灵活采用联合信道编码方式或单独信道编码方式，由于没有改变物理层结构，只是信道编码方案变了，具有可实现性。另外，采用该增强型信道编码方法，在正常循环前缀情况下，使用联合信道编码(20，A)方法，因此相比现有技术来说抗多普勒抗干扰能力强，用户体验比较好。

用户终端在接收到基站下发的带有Speed Depend PUCCH2a2b的消息后，检测自己的移动速度或多普勒频移，当自身的移动速度超过速度阈值Vx或多普勒频移超过多普勒频移高阈值Fx，则触发事件报告，该事件报告在此设定为C1，终端上报自己的移动速度或多普勒频移给基站。
当基站接收到用户终端上报的C1事件后进行判决，认为有必要启动针对ACK/NACK和CSI联合编码功能，然后通知用户终端启动联合编码，用户终端在接收到通知消息后，将ACK/NACK和CSI进行联合编码，上报联合编码给基站，基站收到联合编码，采用联合解码进行解码，联合编码采用现有技术(20，A)编码方法，b0，b1，b2，b3，...，bB-1whereB＝20，
