Description

混合自动重传请求的指示方法、装置及存储介质
本申请要求于2019年09月17日提交中国专利局、申请号为201910877641.8、申请名称为“混合自动重传请求的指示方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种混合自动重传请求的指示方法、装置及存储介质。
背景技术
在现有的通信系统中通常采用混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)来保证数据传输的可靠性。例如，发送端可以在待发送的数据中增加一些冗余信息，使得接收端在接收到数据时能够根据这些冗余信息来纠正数据中的部分错误，以便减少重传次数。对于接收端无法纠正的错误，接收端需要请求发送端重新发送数据。
随着通信技术的发展，卫星通信已经成为移动通信的重要组成部分，卫星通信具备通信距离远、覆盖面积大、组网灵活等特点，可以为各种固定终端或移动终端提供服务。
但是卫星通信系统中信号的往返传输时延较大，导致接收端用于请求发送端重新发送数据的信息无法即时到达发送端，而发送端重新发送的数据也无法即时到达接收端，使得HARQ功能的优势无法在卫星通信系统中很好的体现出来，因此，现有技术中亟需一种能够指示HARQ功能开启或关闭的方法。
发明内容
本申请提供了一种混合自动重传请求的指示方法、装置及存储介质，以实现一种能够指示HARQ功能开启或关闭的方法，使得卫星通信系统中的HARQ功能可以根据实际需求进行开启或关闭。
第一方面，本申请提供了一种混合自动重传请求的指示方法，该方法包括：网络设备通过RRC消息来承载指示HARQ功能开启或关闭的指示信息，并向终端发送该RRC消息。当终端接收到网络设备发送的RRC消息时，该终端可根据该指示信息确定当前服务小区中的HARQ功能开启或关闭。通过本实施例提供的方案，实现了一种能够指示HARQ功能开启或关闭的方法，使得卫星通信系统中的HARQ功能可以根据实际需求进行开启或关闭，从而提高了HARQ功能的灵活性。另外，通过数据信道资源、广播信道资源、资源块中的至少一种资源来承载该指示信息，相比于通过控制信道资源来指示HARQ功能开启或关闭，不仅节省了宝贵的控制信道资源，同时还可避免频繁的指示HARQ功能开启或关闭而造成的空口资源浪费。
在一种可能的设计中，所述RRC消息包括服务小区下行数据信道配置信息块，所述指示信息为服务小区下行数据信道配置信息块中用来指示服务小区所支持的HARQ的进程数的字段。通过本实施例提供的方案，RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在一种可能的设计中，通过服务小区所支持的HARQ的进程数为不同于现有技术的取值来指示HARQ功能关闭。例如，现有技术中服务小区所支持的下行HARQ的最大进程数可配置为2、4、6、10、12、16。本实施例可通过当服务小区所支持的下行HARQ的最大进程数被配置为不同于现有技术的取值来指示HARQ功能关闭。
在一种可能的设计中，服务小区所支持的下行HARQ的最大进程数可配置为0、2、4、6、10、12、16。也就是说，0是新增值。当服务小区所支持的下行HARQ的最大进程数被配置为0时，指示下行的HARQ功能关闭。通过本实施例提供的方案，可使得服务小区所支持的下行HARQ的最大进程数被配置为0时指示下行的HARQ功能关闭，从而使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在一种可能的设计中，当服务小区所支持的下行HARQ的最大进程数被配置为0时，指示下行的HARQ功能和上行的HARQ功能被关闭。也就是说，通过在RRC消息中的服务小区下行数据信道配置信息块中用来指示服务小区所支持的HARQ的进程数的字段中增加新的取值0，来同时指示下行的HARQ功能和上行的HARQ功能被关闭，节省了同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启所需的指示开销，提高了指示效率。
在一种可能的设计中，RRC消息包括服务小区上行数据信道配置信息块，所述指示信息为该服务小区上行数据信道配置信息块中新增的一个可选字段，该可选字段用于指示服务小区是否支持HARQ功能。通过本实施例提供的方案，使得RRC消息在已有字段的基础上即可指示HARQ功能关闭或开启，而不需要在RRC消息中通过增加额外的比特数来增加字段，减少了对现有协议的修改。
在一种可能的设计中，在该服务小区上行数据信道配置信息块中新增的可选字段为HARQ-disable-indicator字段，当HARQ-disable-indicator字段不存在时，指示上行HARQ功能开启。当HARQ-disable-indicator字段存在时，指示上行HARQ功能关闭。通过本实施例提供的方案，使得RRC消息在已有字段的基础上即可指示HARQ功能关闭或开启，而不需要在RRC消息中通过增加额外的比特数来增加字段，减少了对现有协议的修改。
在一种可能的设计中，在该服务小区上行数据信道配置信息块中新增的可选字段为HARQ-enable-indicator字段。当HARQ-enable-indicator字段不存在时，指示上行HARQ功能关闭，当HARQ-enable-indicator字段存在时，指示上行HARQ功能开启。通过本实施例提供的方案，使得RRC消息在已有字段的基础上即可指示HARQ功能关闭或开启，而不需要在RRC消息中通过增加额外的比特数来增加字段，减少了对现有协议的修改。
在一种可能的设计中，当HARQ-disable-indicator字段不存在时，还可以同时指示下行的HARQ功能和上行HARQ功能被开启。当HARQ-disable-indicator字段存在时， 同时指示下行的HARQ功能和上行HARQ功能被关闭。也就是说，通过在RRC消息中的PUSCH-ServingCellConfig信息块中新增可选地HARQ-disable-indicator字段，可同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启，节省了同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启所需的指示开销，提高了指示效率。
在一种可能的设计中，当HARQ-enable-indicator字段不存在时，同时指示下行的HARQ功能和上行HARQ功能关闭，当HARQ-enable-indicator字段存在时，同时指示下行的HARQ功能和上行HARQ功能开启。也就是说，通过在RRC消息中的PUSCH-ServingCellConfig信息块中新增可选地HARQ-enable-indicator字段，可同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启，节省了同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启所需的指示开销，提高了指示效率。
在一种可能的设计中，所述指示信息为所述网络设备给所述终端配置的部分带宽的标识信息。
在一种可能的设计中，所述部分带宽的标识信息包括所述部分带宽的标识号。若所述部分带宽的标识号的取值在第一范围内，则所述部分带宽对应的HARQ功能被关闭；若所述部分带宽的标识号的取值在第二范围内，则所述部分带宽对应的HARQ功能被开启。通过本实施例提供的方案，使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在一种可能的设计中，所述第一范围为5-9，所述第二范围为0-4。
在一种可能的设计中，所述第一范围可以不限于5-9，还可以是除5-9之外，并且不同于现有技术的取值范围，例如，10-14、15-19等。
在一种可能的设计中，所述部分带宽为下行部分带宽或上行部分带宽。也就是说，当下行的BWP-ID字段的取值在第一范围内时，下行的HARQ功能被关闭，当下行的BWP-ID字段的取值在第二范围内时，下行的HARQ功能被开启。当上行的BWP-ID字段的取值在第一范围，例如5-9时，上行的HARQ功能被关闭，当上行的BWP-ID字段的取值在第二范围，例如0-4时，上行的HARQ功能被开启。通过扩展RRC消息中BWP-Downlink信息块中的BWP-ID字段的取值范围，来指示下行的HARQ功能被关闭或开启，通过扩展RRC消息中BWP-Uplink信息块中的BWP-ID字段的取值范围，来指示上行的HARQ功能被关闭或开启，从而使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在一种可能的设计中，RRC消息包括管理信息库MIB信息块，所述指示信息为MIB信息块中的一个空余的spare字段。spare字段对应的一个比特来指示服务小区是否支持HARQ功能。通过MIB信息块中的spare字段来指示服务小区是否支持HARQ功能，由于该spare字段是该MIB信息块中的一个空余比特，因此，通过spare字段来指示服务小区是否支持HARQ功能，可使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改，提高了对现有协议的兼容性。
在一种可能的设计中，当spare字段取值为0时，指示上行的HARQ功能和下行的HARQ功能均被开启。当spare字段取值为1时，指示上行的HARQ功能和下行的HARQ功能均被关闭。
在一种可能的设计中，当spare字段取值为0时，指示上行的HARQ功能和下行的HARQ功能均被关闭。当spare字段取值为1时，指示上行的HARQ功能和下行的HARQ功能均被开启。
在一种可能的设计中，当spare字段取值为0时，指示上行的HARQ功能被开启，下行的HARQ功能采用默认配置。
在一种可能的设计中，当spare字段取值为0时，指示下行的HARQ功能被开启，上行的HARQ功能采用默认配置。

其中，1)网络设备11可以是网络侧设备，例如，无线局域网(Wireless Local Area Network，WLAN)的接入点(Access Point,AP)、4G的演进型基站(Evolved Node B，eNB或eNodeB)、下一代通信的基站，如5G的新无线接入技术(New Radio Access Technology，NR)基站(next generation Node B，gNB)或小站、微站，还可以是中继站、发送和接收点(Transmission and Reception Point，TRP)、路边单元(Road Side Unit,RSU)等。在本实施例中，不同通信制式的通信系统中的基站不同。为了区别起见，将4G通信系统的基站称为长期演进(Long Term Evolution，LTE)eNB，5G通 信系统的基站称为NR gNB，既支持4G通信系统又支持5G通信系统的基站称为演进型长期演进(Evolutional Long Term Evolution，eLTE)eNB,这些名称仅为了方便区别，并不具有限制意义。
2)终端12又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、具有车与车(vehicle to vehicle，V2V)通信能力的车辆等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
3)“多个”是指两个或两个以上，其它量词与之类似。“和/或”，描述关联对象的对应关系，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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，图1所示的通信系统中所包含的终端12的数量和类型仅仅是一种举例，本申请实施例并不限制于此。例如，还可以包括更多的与网络设备11进行通信的终端12，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备11和终端12，但是该通信系统可以并不限于包括网络设备11和终端12，例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于4G无线通信系统、车对外界(vehicle to everything，V2X)通信系统、设备到设备(Device-to-Device,D2D)通信系统、LTE的后续演化等通信系统，还可应用于下一代无线通信系统,即5G通信系统，以及应用于未来可能出现的其他系统,例如下一代的wifi网络、5G车联网等。需要说明的是，随着通信系统的不断演进，未来可能出现的其他系统中，上述各个网元的名称可能会发生变化，在这种情况下，本申请实施例提供的方案同样适用。
在现有的通信系统中通常采用混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)来保证数据传输的可靠性。具体的，HARQ是一种结合了前向纠错(Forward Error Correction，FEC)和自动重传请求(Automatic Repeat Request，ARQ)的技术。例如，发送端可以在待发送的数据中增加一些冗余信息，使得接收端在接收到数据时能够根据这些冗余信息来纠正数据中的部分错误，也就是说，接收端可以通过FEC来纠正数据中的部分错误以便减少重传次数。对接收端无法通过FEC纠正的错误，接收端需要通过ARQ来请求发送端重新发送数据。例如，接收端采用检错码检测接收到的数据中是否有错误，如果无错，则接收端向发送端发送确认信息(Acknowledgement,ACK)，使得发送端发送新的数据。如果有错，则接收端向发送端发送不确认信息(Non-Acknowledge,NACK)，使得发送端重新发送相同的数据。
随着通信技术的发展，卫星通信已经成为移动通信的重要组成部分，卫星通信具备通信距离远、覆盖面积大、组网灵活等特点，可以为各种固定终端或移动终端提供服务。
但是卫星通信系统中信号的往返传输时延较大，例如，第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)组织研究显示,低轨道(Low Earth Orbit，LEO) 卫星(600公里)的往返传输时延是28.408毫秒，中轨道(Medium Earth Orbit，MEO)卫星(高度10000公里)的往返传输时延是190.38毫秒，同步轨道(Geostationary Earth orbit，GEO)卫星(高度35786公里)往返传输时延是544.75毫秒。导致接收端用于请求发送端重新发送数据的信息无法即时到达发送端，而发送端重新发送的数据也无法即时到达接收端，使得HARQ快速反馈的优势无法在卫星通信系统中很好的体现出来。而在卫星通信系统中，重传任务可以通过上层协议来完成，例如，通过无线链路控制(Radio link control，RLC)层来实现重传。因此，在卫星通信系统中亟需一种能够指示HARQ功能开启或关闭的方法。
一种可能的实现方式是，采用控制信道资源来承载指示HARQ功能开启或关闭的指示信息，例如，通过下行控制信息(Downlink Control Information，DCI)来承载该指示信息。具体的，DCI的帧格式可以有多种，图2所示的是DCI的一种帧格式。如图2所示，DCI中的每个字段均已经定义好了，如果需要DCI来控制HARQ功能开启或关闭，则需要对DCI当前的帧格式进行修改，例如，在现有帧格式的基础上扩展出一个字段，使得扩展出的字段能够指示HARQ功能开启或关闭，同时还需要增加HARQ进程数，使得HARQ进程号对应的比特位增加。
但是，对DCI当前的帧格式进行修改会产生如下几方面的问题，例如，会对现有的通信协议和实现产生较大的冲突。另外，由于DCI承载于物理下行控制信道(Physical Downlink Control Channel,PDCCH)上，而PDCCH信道资源是非常有限的资源，在DCI中扩展几个比特都可能需要精心的设计，例如，需要重新设计相关的物理层资源。此外，DCI需要在每个TTI发送一次，如果用DCI来控制HARQ功能开启或关闭，则意味着每个TTI需要指示一次HARQ功能开启或关闭，而在通常情况下，HARQ功能并不需要在每个TTI就进行一次开启或关闭，因此，频繁的指示HARQ功能开启或关闭还会造成空口资源的浪费。
针对上面所述的问题，本申请实施例提出了一种通过无线资源控制(Radio resource control，RRC)消息指示HARQ功能开启或关闭的方法。下面结合实施例对该方法进行详细的描述。
本申请实施例提供的一种混合自动重传请求的指示方法可应用于如图3所示的应用场景，该应用场景融合了卫星通信和5G技术。该应用场景中的网元包括：终端、5G基站、地面站和5G核心网。
其中，终端是支持5G新空口的移动设备，例如，手机、平面电脑等移动设备，具体的，终端可通过5G新空口接入卫星网络并发起呼叫、上网等业务。5G基站部署在卫星上，主要用于提供无线接入服务，调度无线资源给接入终端，提供可靠的无线传输协议和数据加密协议等。地面站负责转发卫星基站和5G核心网之间的信令和业务数据。5G核心网负责用户接入控制、移动性管理、会话管理、用户安全认证、计费等业务。5G核心网包括多个功能单元，例如，该多个功能单元中包括控制面的功能实体和数据面的功能实体。例如，接入及移动管理单元(Access and Mobility Management Function，AMF)和会话管理单元(Session Management Function，SMF)属于控制面的功能实体，用户面单元(User Plane Function，UPF)属于数据面的功能实体。其中， AMF负责用户接入管理、安全认证、以及移动性管理。UPF负责管理用户面数据的传输、流量统计、安全窃听等功能。
另外，终端通过5G新空口接入网络，具体的，终端通过5G新空口与5G基站连接，该5G新空口是终端和5G基站之间的无线连接。5G基站和5G基站之间通过Xn接口进行通信，Xn接口主要用于5G基站之间的信令交互和用户数据传输。5G基站通过地面站与5G核心网连接。具体的，5G基站通过NG接口与地面站进行通信，NG接口主要用于交互5G核心网的非接入层(Non-access stratum，NAS)等信令，以及用户的业务数据。
另外，需要说明的是，本申请实施例所述的指示HARQ功能开启或关闭的方法不仅适用于卫星通信系统，还可以适用于如上所述的各种类型的通信系统，例如，5G通信系统。
图4为本申请实施例提供的一种混合自动重传请求的指示方法的信令图。所述的混合自动重传请求的指示方法所涉及的网元包括：网络设备和终端，其中，网络设备可以是如上所述的5G基站或5G核心网中的功能实体。具体的该方法包括如下步骤：
S41、网络设备向终端发送RRC消息，该RRC消息中包括指示信息，该指示信息用于指示HARQ功能开启或关闭。
具体的，该指示信息通过如下至少一种资源来承载，该资源包括：数据信道资源、广播信道资源、资源块。其中，数据信道资源具体可以是物理下行共享信道(Physical Downlink Shared Channel，PDSCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，广播信道资源具体可以是物理广播信道(Physical Broadcast Channel，PBCH)，资源块具体可以是部分带宽(Bandwidth Part，BWP)。
S42、终端根据指示信息，确定HARQ功能开启或关闭。
相应的，当终端接收到该网络设备发送的RRC消息时，从该RRC消息中获取到该指示信息，并根据该指示信息，确定当前服务小区中的HARQ功能是开启或关闭。
本实施例通过RRC消息来承载指示HARQ功能开启或关闭的指示信息，实现了一种能够指示HARQ功能开启或关闭的方法，使得卫星通信系统中的HARQ功能可以根据实际需求进行开启或关闭，从而提高了HARQ功能的灵活性。另外，通过数据信道资源、广播信道资源、资源块中的至少一种资源来承载该指示信息，相比于通过控制信道资源来指示HARQ功能开启或关闭，不仅节省了宝贵的控制信道资源，同时还可避免频繁的指示HARQ功能开启或关闭而造成的空口资源浪费。
下面分别对数据信道资源、广播信道资源、资源块中的至少一个资源来承载该指示信息进行介绍。
在一种可能的实现方式中，所述指示信息为所述RRC消息中的服务小区下行数据信道配置(PDSCH-ServingCellConfig)信息块(Information element，IE)中的nrofHARQ-ProcessesForPDSCH字段，此处，将nrofHARQ-ProcessesForPDSCH字段记为第一字段，所述第一字段用于指示服务小区所支持的HARQ的进程数，例如，下行HARQ的最大进程数。在现有技术中，服务小区所支持的下行HARQ的最大进程数可 配置为2、4、6、10、12、16。此处可采用与现有技术中最大进程数不同的数值来指示HARQ功能关闭。例如，当服务小区所支持的下行HARQ的最大进程数被配置为1、3、5、7、8、9、11、13、14或15时，指示下行的HARQ功能关闭。
在本申请实施例中，服务小区所支持的下行HARQ的最大进程数可配置为0、2、4、6、10、12、16。也就是说，0是新增值。当服务小区所支持的下行HARQ的最大进程数被配置为0时，指示下行的HARQ功能关闭。当服务小区所支持的下行HARQ的最大进程数被配置为2、4、6、10、12、16中的某一个值时，指示下行的HARQ功能开启。
本实施例通在RRC消息中的PDSCH-ServingCellConfig信息块中的nrofHARQ-ProcessesForPDSCH字段中增加新的取值，例如0，使得服务小区所支持的下行HARQ的最大进程数被配置为0时指示下行的HARQ功能关闭，从而使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在上述实施例的基础上，当nrofHARQ-ProcessesForPDSCH字段被配置为1、3、5、7、8、9、11、13、14或15时，还可用于指示下行的HARQ功能和上行的HARQ功能被关闭。或者，当服务小区所支持的下行HARQ的最大进程数被配置为0时，指示下行的HARQ功能和上行的HARQ功能被关闭。当服务小区所支持的下行HARQ的最大进程数被配置为2、4、6、10、12、16中的某一个值时，指示下行的HARQ功能和上行的HARQ功能被开启。也就是说，通过在RRC消息中的PDSCH-ServingCellConfig信息块中的nrofHARQ-ProcessesForPDSCH字段中增加新的取值，同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启，节省了同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启所需的指示开销，提高了指示效率。
在另一种可能的实现方式中，所述指示信息为所述RRC消息中的服务小区上行数据信道配置(PUSCH-ServingCellConfig)信息块中的HARQ关闭指示(HARQ-disable-indicator)字段，此处将HARQ-disable-indicator字段记为第二字段，该HARQ-disable-indicator字段可以是在PUSCH-ServingCellConfig信息块中新增的可选字段。例如，PUSCH-ServingCellConfig信息块中包括多个空余的比特，该多个空余的比特可被划分为多个可选字段，例如，PUSCH-ServingCellConfig信息块中包括三个可选字段。HARQ-disable-indicator字段是该三个可选字段中的一个字段。
具体的，该HARQ-disable-indicator字段用于指示服务小区是否支持HARQ功能，例如是否支持上行HARQ功能。例如，当HARQ-disable-indicator字段不存在时，指示上行HARQ功能开启，并且上行HARQ的进程数为16。当HARQ-disable-indicator字段存在时，指示上行HARQ功能关闭。
可以理解的是，作为在PUSCH-ServingCellConfig信息块中增加HARQ-disable-indicator字段的一种可替换方式是，在PUSCH-ServingCellConfig信息块中增加HARQ开启指示(HARQ-enable-indicator)字段。具体的，当 HARQ-enable-indicator字段不存在时，指示上行HARQ功能关闭，当HARQ-enable-indicator字段存在时，指示上行HARQ功能开启。
本实施例通过在RRC消息中的PUSCH-ServingCellConfig信息块中增加可选地HARQ-disable-indicator字段，当HARQ-disable-indicator字段不存在时，指示上行HARQ功能开启，当HARQ-disable-indicator字段存在时，指示上行HARQ功能关闭，从而使得RRC消息在已有字段的基础上即可指示HARQ功能关闭或开启，而不需要在RRC消息中通过增加额外的比特数来增加字段，减少了对现有协议的修改。
在上述实施例的基础上，当HARQ-disable-indicator字段不存在时，还可以同时指示下行的HARQ功能和上行HARQ功能被开启。当HARQ-disable-indicator字段存在时，同时指示下行的HARQ功能和上行HARQ功能被关闭。
或者，当HARQ-enable-indicator字段不存在时，同时指示下行的HARQ功能和上行HARQ功能关闭，当HARQ-enable-indicator字段存在时，同时指示下行的HARQ功能和上行HARQ功能开启。也就是说，通过在RRC消息中的PUSCH-ServingCellConfig信息块中新增可选地HARQ-disable-indicator字段或HARQ-enable-indicator字段，可同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启，节省了同时指示下行的HARQ功能和上行的HARQ功能被关闭或开启所需的指示开销，提高了指示效率。
在又一种可能的实现方式中，所述指示信息为所述网络设备给所述终端配置的部分带宽的标识信息，部分带宽的标识信息具体可以是部分带宽的标识号(BWP-ID)。
可以理解的是，在上行方向上，网络设备可以给终端最多配置4个BWP。在下行方向上，网络设备可以给终端最多配置4个BWP。本实施例中的RRC消息可以是与BWP相关的RRC消息。具体的，该RRC消息可以包括下行BWP(BWP-Downlink)信息块和上行BWP(BWP-Uplink)信息块。其中，BWP-Downlink信息块中包括下行的BWP-ID字段，BWP-Uplink信息块中包括上行的BWP-ID字段。
以下行的BWP-ID为例，当下行的BWP-ID字段的取值在第一范围内时，下行的HARQ功能被关闭，当下行的BWP-ID字段的取值在第二范围内时，下行的HARQ功能被开启。具体的，第一范围为5-9，第二范围为0-4。例如，当BWP-ID为0时，BWP-ID为0的BWP对应的HARQ功能被开启。当BWP-ID为1-4中的某一个值，例如，BWP-ID为1时，BWP-ID为1的BWP对应的HARQ功能被开启。其中，BWP-ID为0的BWP可用于终端进行网络接入。BWP-ID为1-4的BWP可用于终端进行数据传输。当BWP-ID为5-9中的某一个值时，相应的BWP对应的HARQ功能被关闭。
同理，当上行的BWP-ID字段的取值在第一范围，例如5-9时，上行的HARQ功能被关闭，当上行的BWP-ID字段的取值在第二范围，例如0-4时，上行的HARQ功能被开启。例如，在上行方向上，网络设备给终端配置了4个BWP，该4个BWP的ID依次为1、2、6、7，则BWP-ID＝1的BWP和BWP-ID＝2的BWP对应的HARQ功能被开启。BWP-ID＝6的BWP和BWP-ID＝7的BWP对应的HARQ功能被关闭。
可以理解的是，现有技术中BWP-ID字段的取值范围为0-4，本实施例采用0-4范 围内的BWP-ID指示HARQ功能开启，采用0-4之外的取值范围，例如，5-9指示HARQ功能关闭。但是，5-9只是不同于现有技术中0-4的一个取值范围，在一些实施例中，如上所述的第一范围可以不限于5-9，还可以是除5-9之外，并且不同于现有技术的取值范围，例如，10-14、15-19等。
另外，需要注意的是，虽然网络设备可以给终端配置4个BWP，但是每次激活的BWP为一个，具体激活该4个BWP中的哪个，需要由DCI中的部分带宽指示(Bandwidth part indicator)字段来指示。Bandwidth part indicator字段包括两个比特，两个比特可以有4种取值。例如，在上行方向上，网络设备给终端配置了4个BWP，该4个BWP的ID依次为1、2、6、7。Bandwidth part indicator字段的两个比特的4种取值和激活的BWP的ID之间的对应关系可以如下表1所示：
表1
Figure PCTCN2020113780-appb-000001
可以理解的是，如表1所示的Bandwidth part indicator字段的两个比特的4种取值和激活的BWP的ID之间的对应关系只是一种示意性举例，本实施例并不限定该对应关系。一方面，当网络设备给终端配置的BWP的ID发生变化时，该对应关系也会随着变化，例如，当网络设备给终端配置的BWP的ID依次为1、2、8、9时，“10”用于指示激活的BWP的ID为8，“11”用于指示激活的BWP的ID为9。另一方面，Bandwidth part indicator字段的取值的大小和激活的BWP的ID的大小之间的关系可以不是如表1所示的这种正相关的关系，例如，可以是负相关的关系，如下表2所示，或者可以是其他的随机关系，如下表3所示。

表3

Figure PCTCN2020113780-appb-000004
本实施例通过扩展RRC消息中BWP-Downlink信息块中的BWP-ID字段的取值范围，来指示下行的HARQ功能被关闭或开启，通过扩展RRC消息中BWP-Uplink信息块中的BWP-ID字段的取值范围，来指示上行的HARQ功能被关闭或开启，从而使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改。
在又一种可能的实现方式中，所述指示信息为所述RRC消息中的管理信息库(Management Information Base，MIB)信息块中的spare字段，此处将spare字段记为第三字段，在现有技术中，spare字段是MIB信息块中的一个空余比特，在本实施例中，通过spare字段对应的一个比特来指示服务小区是否支持HARQ功能。
具体的，当spare字段取值为0时，指示上行的HARQ功能和下行的HARQ功能均被开启。当spare字段取值为1时，指示上行的HARQ功能和下行的HARQ功能均被关闭。
或者，当spare字段取值为0时，指示上行的HARQ功能和下行的HARQ功能均被关闭。当spare字段取值为1时，指示上行的HARQ功能和下行的HARQ功能均被开启。
可以理解的是，spare字段也可以指示上行的HARQ功能和下行的HARQ功能中的一个开启或关闭。例如，当spare字段取值为0时，指示上行的HARQ功能被开启，下行的HARQ功能采用默认配置，例如，下行的HARQ功能在默认模式中被配置为关闭。当spare字段取值为1时，指示上行的HARQ功能被关闭，下行的HARQ功能依然采用默认配置。
或者，当spare字段取值为0时，指示下行的HARQ功能被开启，上行的HARQ功能采用默认配置，例如，上行的HARQ功能在默认模式中被配置为关闭。当spare字段取值为1时，指示下行的HARQ功能被关闭，上行的HARQ功能依然采用默认配置。
本实施例通过MIB信息块中的spare字段来指示服务小区是否支持HARQ功能，由于该spare字段是该MIB信息块中的一个空余比特，因此，通过spare字段来指示服务小区是否支持HARQ功能，可使得RRC消息在不进行帧格式修改的情况下，即可用于指示HARQ功能关闭或开启，减少了对现有协议的修改，提高了对现有协议的兼容性。
可以理解的是，上述实施例中的部分或全部步骤骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
可以理解的是，以上各个实施例中，由终端实现的操作或者步骤，也可以由可用 于终端的部件(例如芯片或者电路)实现，由网络设备实现的操作或者步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。
