Description

通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在移动通信系统中，用户设备(User Equipment，UE)在进行异频或异系统切换之前，首先要进行异频或异系统的测量。当UE所在的当前服务小区信号较差，异频或异系统测量被触发后，基站(Evolutional Node B，eNB)会下发测量间隙(gap)配置指示给UE，测量gap配置指示包括测量gap的测量周期、测量gap的测量窗口和测量起始时间，比如，测量gap的测量窗口是6ms，测量周期为40ms或80ms。UE接收到测量gap配置指示后，UE按照测量gap配置指示启动测量gap。UE通常只有一个接收机，同一时刻只能在一个频点上接收信号，所以在测量gap窗口内，UE无法处理上下行所有信道，即UE不进行数据传输，例如测量gap周期为40ms时，UE在每40ms有连续的6ms无法处理上下行所有信道。
频分双工(Frequency Division Duplex，FDD)上行是同步混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)，同一HARQ通道的重传固定在8ms之后。物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)初传和重传会使用不同的冗余版本号，通信协议36.321中给出冗余版本序列为0、2、3、1，重传和重传的上一次传输按照所给出的冗余版本序列累加变化，以初传和重传为例，如初传使用冗余版本号0，则下一次重传使用冗余版本号2，冗余版本号代表传输的数据块包含不同的冗余部分，eNB通过合并携带不同冗余部分的数据块增加合并增益。
如果eNB上行调度时初传和重传完全避让测量gap影响，需要保证物理下行控制信道(Physical Downlink Control Channel，PDCCH)、PUSCH以及物理HARQ指示信道(Physical HARQ Indicator Channel，PHICH)都不落在测量gap窗口内，上行可调度子帧数大幅减少，上行速率下降明显。所以，eNB上行调度只会避免初传时的部分信道落在测量gap窗口内，PUSCH重传有可能落在测量gap窗口内。而通信协议36.321规定，若UE上行PUSCH传输是由于测量gap导致无法发送数据时，此HARQ通道下一次重传时会进行PUSCH非自适应重传，非自适应重传时，UE使用上一次PUSCH传输的资源进行重传，重传时使用的冗余版本号不累加变化。在实际应用中，可能会出现UE侧实现错误导致重传时使用的冗余版本号会根据冗余版本序列发生变化，而eNB侧根据通信协议36.321的规定重传时使用的冗余版本号不累加变化，因此存在eNB和UE两侧冗余版本号不一致的风险，导致PUSCH误码率抬升。
发明内容

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)以及第五代移动通信(the 5th Generation mobile communication technology，5G)系统。
本申请涉及的通信装置主要包括网络设备和终端设备。
网络设备：可以是基站，或者接入点，或者接入网设备，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。网络设备可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。例如，网络设备可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站，例如gNB等，在此并不限定。
终端设备：可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经RAN与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
图1为一种通信系统架构示意图，如图1所示，本申请实施例的通信系统可以包括一个或多个网络设备和一个或多个终端设备，网络设备和终端设备之间进行通信。
相关技术中，若按照通信协议36.321的规定，UE上行PUSCH传输是由于测量间隙导致无法发送数据时，即UE在测量间隙窗口内无法发送数据，发送数据所使用的HARQ通道下一次重传时会进行PUSCH非自适应重传，非自适应重传时，UE使用上一次PUSCH传输的资源进行重传，重传时使用的冗余版本号不累加变化，在实际应用中，可能会出现UE侧实现错误导致重传时使用的冗余版本号会根据冗余版本序列发生变化，而eNB侧根据通信协议36.321的规定重传时使用的冗余版本号不累加变化，因此存在eNB和UE两侧冗余版本号不一致的风险，导致PUSCH误码率抬升。为解决这一问题，本申请实施例提供一种通信方法，网络设备未接收到终端设备PUSCH发送的数据时，通过在确定出终端设备未进行数据发送的时间在测量间隙窗口内时，指示终端设备下一次HARQ重传使用的冗余版本号，终端设备根据网络设备指示的冗余版本号进行数据重传，因此可保证网络设备和终端设备两侧的冗余版本号一致，从而可消除网络设备和终端设备两侧冗余版本号不一致的风险，降低PUSCH误码率。下面结合附图详细说明本申请实施例提供的通信方法及装置。
图2为本申请提供的一种通信方法实施例的交互流程图，如图2所示，本实施例的方法可以包括：
S101、网络设备通过PDCCH向终端设备发送调度请求，调度请求用于指示终端 设备根据预设的时间间隔向网络设备发送数据。
S102、终端设备根据预设的时间间隔通过PUSCH向网络设备发送数据。
具体地，网络设备通过PDCCH向终端设备发送调度请求，该调度请求用于指示终端设备可向网络设备发送数据，终端设备接收到调用请求后，开始在预设的时间间隔上向网络设备发送数据，该预设的时间间隔是网络设备和终端设备已知的，或者携带在调度请求中，例如时间间隔为8ms，终端设备接收到调用请求后通过PUSCH向网络设备初传一次数据，若初传数据失败，则在8ms之后进行第一次重传，若第一次重传失败，则在第一次重传的8ms之后进行第二次重传。相应地，网络设备在预设的时间间隔上接收终端设备发送的数据。
S103、网络设备未接收到终端设备通过PUSCH发送的数据时，根据终端设备的测量间隙配置信息确定终端设备本次未进行数据发送的时间是否在测量间隙窗口内，测量间隙配置信息包括测量间隙的测量周期、测量间隙窗口和测量起始时间。
具体地，例如，网络设备在终端设备初传数据的时间未接收到数据，则根据终端设备的测量间隙配置信息确定终端设备初传数据的时间是否在测量间隙窗口内。测量间隙配置信息包括测量间隙的测量周期、测量间隙窗口和测量起始时间，例如，测量间隙窗口是6ms，测量周期为40ms，每40ms有连续的6ms是用于终端设备进行异频或异系统的测量的，每40ms有连续的6ms终端设备是不进行数据发送的，因此网络设备在这6ms内是接收不到终端设备发送的数据的。其中的测量间隙配置信息是网络设备配置给终端设备的，作为一种配置的方式，本实施例的方法还可以包括：
终端设备向网络设备发送用于指示终端设备当前服务小区信号值小于预设阈值的测量报告。
网络设备接收到终端设备发送的用于指示终端设备当前服务小区信号值小于预设阈值的测量报告时，向终端设备发送测量间隙配置信息。
具体地，当终端设备所在的当前服务小区信号较差，即终端设备当前服务小区信号值小于预设阈值时，向网络设备发送测量报告，告知网络设备当前服务小区信号较差，网络设备接收到测量报告时，向终端设备发送测量间隙配置信息，终端设备接收到测量间隙配置信息后，启动异频或异系统的测量，以进行异频或异系统切换。该测量间隙配置信息时网络设备配置给终端设备的，因此网络设备是已知配置给该终端设备的测量间隙配置信息的。
可选的，S103中网络设备根据终端设备的测量间隙配置信息确定终端设备本次未进行数据发送的时间是否在测量间隙窗口内，具体可以为：
网络设备根据测量间隙的测量周期、测量间隙窗口和测量起始时间，计算终端设备本次未进行数据发送的时间是否在测量间隙窗口内，例如，测量间隙窗口是6ms，测量周期为80ms，网络设备根据向终端设备发送的调度请求可获知终端设备每一次传输数据的时间，从测量起始时间开始，网络设备可计算出终端设备本次未进行数据发送的时间是否在一个80ms测量周期中6ms的测量间隙窗口内。
S104、若网络设备确定终端设备本次未进行数据发送的时间在测量间隙窗口内，则向终端设备发送下一次HARQ重传使用的冗余版本号。
具体地，作为一种可实施的方式，网络设备向终端设备发送下一次HARQ重传使 用的冗余版本号可以是：网络设备向所述终端设备发送PDCCH，所述PDCCH中携带所述冗余版本号。例如，具体可以是通过下行控制信息(Downlink Control Information，DCI)0指示终端设备下一次HARQ重传使用的冗余版本号。相应地，终端设备接收网络设备发送的PDCCH，所述PDCCH中携带所述冗余版本号。
S105、终端设备使用本次未进行数据发送所占用的HARQ通道根据所接收到的冗余版本号向网络设备重传数据。
本实施例中，可选的，在S101之前或之后，本实施例的方法还可以包括：
S106、网络设备为所述终端设备的每个上行HARQ通道设置一测量间隙冲突标识，并设置所述测量间隙冲突标识的初始值为第一值。
具体地，同一HARQ通道的重传固定在8ms之后，上行HARQ通道一共有8个，网络设备设置这8个上行HARQ通道的测量间隙冲突标识的初始值为第一值。
S107、若确定终端设备本次未进行数据发送的时间在测量间隙窗口内，则将终端设备本次未进行数据发送所占用的HARQ通道的测量间隙冲突标识的值设置为第二值，其中，测量间隙冲突标识的值为所述第一值的HARQ通道在下一次重传时使用非自适应重传，测量间隙冲突标识的值为所述第二值的HARQ通道在下一次重传时使用自适应重传。
具体地，例如，第一值为0，第二值为1，测量间隙冲突标识的值为0的HARQ通道在下一次重传时使用非自适应重传，非自适应重传时，终端设备使用上一次PUSCH传输的资源进行重传，重传时使用的冗余版本号不累加变化。测量间隙冲突标识的值为1的HARQ通道在下一次重传时使用自适应重传，自适应重传时，网络设备向终端设备发送下一次HARQ重传使用的冗余版本号，通过指示终端设备下一次HARQ重传使用的冗余版本号，终端设备根据网络设备指示的冗余版本号进行数据重传，因此可保证网络设备和终端设备两侧的冗余版本号一致，从而可消除网络设备和终端设备两侧冗余版本号不一致的风险，降低PUSCH误码率。第一值和第二值还可以是其它，本申请实施例对此不做限制。
本实施例中，通过为每个HARQ通道设置一测量间隙冲突标识，测量间隙冲突标识的初始值为第一值，当网络设备确定终端设备本次未进行数据发送的时间在测量间隙窗口内，则将终端设备本次未进行数据发送所占用的HARQ通道的测量间隙冲突标识的值设置为第二值，从而在使用每个HARQ通道进行数据传输时，可根据测量间隙冲突标识的值来确定每个HARQ通道下一次进行数据重传的方式，可提高数据重传的效率，还可记录终端设备每一次数据传输的历史状态。
本实施例提供的通信方法，通过网络设备向终端设备发送调度请求之后，在未接收到终端设备通过PUSCH发送的数据时，根据终端设备的测量间隙配置信息确定终端设备本次未进行数据发送的时间是否在测量间隙窗口内，若是，则向终端设备发送下一次HARQ重传使用的冗余版本号，终端设备可根据网络设备指示的冗余版本号进行数据重传，因此可保证网络设备和终端设备两侧的冗余版本号一致，从而可消除网络设备和终端设备两侧冗余版本号不一致的风险，降低PUSCH误码率。

S207、若网络设备确定终端设备本次未进行数据发送的时间在测量间隙窗口内，将终端设备本次未进行数据发送所占用的HARQ通道的测量间隙冲突标识的值设置为第二值。
其中，测量间隙冲突标识的值为第一值的HARQ通道在下一次重传时使用非自适应重传，测量间隙冲突标识的值为第二值的HARQ通道在下一次重传时使用自适应重传。
S208、本次未进行数据发送所占用的HARQ通道8ms后进行重传时，网络设备确定HARQ通道的测量间隙冲突标识的值为第二值时，确定本次HARQ使用自适应重传，则向终端设备发送本次HARQ重传使用的冗余版本号。
