具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,简称为“GSM”)系统、码分多址(Code Division Multiple Access,简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service,简称为“GPRS”)、长期演进(Long Term Evolution,简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex,简称为“FDD”)系统、LTE时分双工(Time Division Duplex,简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System,简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access,简称为“WiMAX”)通信系统或未来的5G系统等。
图1示出了本申请实施例应用的无线通信系统100。该无线通信系统100可以包括网络设备110。网络设备100可以是与终端设备通信的设备。网络设备100可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备(例如UE)进行通信。可选地,该网络设备100可以是GSM系统或CDMA系统中的基站(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),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,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、未来5G网络中的网络侧设备或者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。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或固定的。可选地,终端设备120可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地,5G系统或网络还可以称为新无线(New Radio,NR)系统或网络。
应理解,图1示只是例性地示出了一个网络设备和两个终端设备,可选地,该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
现有技术中,通过无线资源控制(Radio Resource Control,RRC)层为每一个终端设备配置一套DRX参数,也就是说终端设备的多种业务对应的是同一套DRX参数。但是由于终端设备的不同业务的要求不同,例如,对于某些周期较长的周期性的业务,休眠时间需要设置的较长,而对于某些实时性较强的业务,休眠时间需要设置的较短,这时均采用同一套DRX参数显然不利于执行各种不同类型的业务。因此,本申请实施例提出了一种通信方法,在该方法中,能够直接确定终端设备的某个业务对应的DRX参数,与现有技术相比更加灵活,下面结合图2和图3对本申请实施例的通信方法进行详细的描述。
图2是本申请实施例的通信方法的示意性流程图。图2的方法包括:
210、终端设备确定目标业务对应的DRX参数。
上述目标业务可以是终端设备将要执行的业务,例如,该目标业务可以是终端设备从网络设备接收下行数据。
另外,不同的目标业务既可以对应相同的DRX参数,也可以对应不同的DRX参数。例如,如果两种业务对传输数据的时延要求很接近,那么这两种业务可以对应相同的DRX参数;当这两种业务对传输数据的时延要求相差较大时,这两种业务可以分别对应不同的DRX参数。
可选地,上述目标业务的业务类型信息可以包括:目标业务的数据所属的逻辑信道标识(Logical Channel Identif,LCID)或者逻辑信道组标识、该目标业务的数据的服务质量分流标识(Quality of Service Flow Identif,QoS-Flow-ID),以及所述目标业务的数据所属的数据无线承载(Data Radio Bearer,DRB)中的至少一种。
可选地,图3的方法还包括:终端设备接收网络设备发送的第一指示信息,该第一指示信息指示所述目标业务对应的DRX参数。在接收到第一指示信息之后,终端设备就可以直接根据第一指示信息来确定目标业务对应的DRX参数,简化了终端设备确定DRX参数的过程。
第一指示信息在指示DRX参数时可以有多种实现方式,可选地,上述第一指示信息可以直接指示目标业务对应的DRX参数在预先配置的多种DRX参数中的索引。这样,终端设备在接收到第一指示信息之后可以根据第一指示信息确定目标业务对应的DRX参数在预先配置的多种DRX参数中的索引,然后根据该索引从预先存储的多种DRX参数中确定与目标业务对应的DRX参数。
当第一指示信息以索引的方式指示DRX参数时,使用较小的比特位就能够指示出目标业务对应的DRX参数,不仅能够实现对DRX参数的指示,还能够节省一定的信令开销
例如,终端设备预先配置10种DRX参数,第一指示信息指示目标业务对应的DRX参数在预先配置的10种DRX参数中的索引号为5,那么终端设备在接收到第一指示信息后就可以确定预先配置的10种参数中索引号为5的DRX参数为目标业务对应的DRX参数。
可选地,上述第一指示信息除了可以指示DRX参数的索引之外,还可以直接指示目标业务对应的DRX参数的参数值。这样终端设备在接收到第一指示信息之后就可以直接确定目标业务对应的DRX参数的参数值,此时 终端设备可以不必预先配置多种DRX参数,因为,终端设备通过第一指示信息就可以直接确定目标业务对应的DRX参数的参数值,与指示DRX索引的方式相比能够更快地确定目标业务对应的DRX参数的参数值。
可选地,上述第一指示信息可以承载在下行控制信息(Digital Copyright Identifier,DCI)或者媒体接入控制单元(Media Access Control Control Element,MAC CE)中。当第一指示信息承载在DCI或者MAC CE中时,能够通过第一指示信息来动态指示确定目标业务对应的DRX参数。
可选地,终端设备除了根据网络设备的指示来确定目标业务对应的DRX参数之外,还可以直接根据目标业务的业务类型,以及业务类型与DRX参数的对应关系,从预先配置的多种DRX参数中确定目标业务对应的DRX参数。预先配置的多种DRX参数可以是网络设备之前通过配置信令为网络设备配置的。
具体地,目标业务的数据所属的逻辑信道(或者逻辑信道组)、目标业务的数据的服务质量分流标识以及目标业务的数据所属的DRB这三种信息均可以与DRX有一定的对应关系,也就是说,同一DRX参数可以同时对应上述三种信息,具体地,一个DRX参数可以对应一个逻辑信道(逻辑信道组)标识、一个服务质量分流标识以及一个DRB。终端设备在确定DRX参数时可以利用上述三者信息中的任一个信息与DRX参数的对应关系来确定目标业务对应的DRX参数。
例如,第一逻辑信道的数据对应第一套DRX参数,第二逻辑信道的数据对应第二套DRX参数,第三逻辑信道的数据对应第三套DRX参数,那么当目标业务的数据属于第一逻辑信道时,该目标业务对应的DRX参数就是第一套DRX参数。
另外,当目标业务为语音业务时,由于语音包的周期性,终端设备可以迅速进入休眠期以达到省电效果,此时终端设备在确定目标业务对应的DRX参数时,可以将具有较短DRX非激活定时器(DRX inactivity timer)的DRX参数确定为该目标业务对应的DRX参数,以使得终端设备在以非连续接收的方式接收数据时能够快速进入休眠期。
当目标业务为下载业务时,基站可能会持续调度终端设备一段时间,此时较长的DRX非激活定时器有利于终端设备更快速的响应。因此,终端设备可以将具有较长DRX非激活定时器(DRX inactivity timer)的DRX参数 确定为该目标业务对应的DRX参数。
由于不同业务类型的需求不同,因此,为不同的业务配置不同的DRX参数是有必要的,并且根据业务类型来确定DRX参数能够提高用户体验和保证QoS。
可选地,目标业务的业务类型可以是终端设备从网络设备接收的第二指示信息获取的,此时第二指示信息指示的是目标业务的业务类型。另外,该第二指示信息具体可以是索引信息,该第二指示信息可以具体指示目标业务的业务类型在多种业务类型的索引信息。具体地,假设一共存在10种业务类型,那么这10种业务类型分别对应索引号1-10,这时第二指示信息在值业务类型时可以直接指示目标业务的业务类型在这10种业务类型中的索引号。
220、所述终端设备根据所述目标业务对应的DRX参数以非连续接收的方式执行所述目标业务。
现有技术中,通过无线资源控制RRC层为每一个终端设备(媒体访问控制MAC实体)配置一种DRX参数,也就是说终端设备的不同的业务对应的都是同一套DRX参数,而不同业务类型的传输需求可能并不相同,不适合采用同一套DRX参数。而本申请中,确定DRX参数的方式更加灵活,例如,可以根据不同的业务类型确定业务对应的DRX参数。
可选地,上述DRX参数可以包括持续时间定时器(on Duration Timer)、DRX非激活定时器(DRX-Inactivity Timer)、DRX重传定时器(DRX-Retransmission Timer)、长DRX周期偏移(long DRX-Cycle Start Offset)、短DRX周期(short DRX-Cycle)和DRX短周期定时器(DRX-ShortCycle Timer)中的至少一种。应理解,不同的业务对应DRX参数中包含的参数的类型可能不同,例如,某些要求较低的业务对应的DRX参数可能只包含上述参数中的一种,而某些要求较高的业务对应的DRX参数中可能会包含上述参数中的至少两种。
下面结合图3和图4对DRX参数进行说明。
如图3所示,一个完整的DRX周期由激活期和休眠期组成,on Duration Timer是在每个DRX周期内DRX需要监听的物理下行控制信道(Physical Downlink Control Channel,PDCCH)的子帧数目,当超过了on Duration Timer的时间后,终端设备就可以关闭其接收机,进入休眠状态。
DRX-Inactivity Timer是终端设备成功解码指示上行或者下行初始传输的PDCCH后所连续监听的非活动的PDCCH的子帧数目,在此时间内,终端设备必须没有监听到相关的PDCCH后,终端设备才能进行DRX状态。
图4示出了数据重传的过程。该过程包括:
410、终端设备接收数据。
终端设备接收数据后解码数据失败,启动混合自动重传请求往返时间定时器(Hybrid Auto Repeat Request Round Trip Time Timer,HARQ RTT Timer)。
420、终端设备向基站反馈NACK信息。
430、终端设备启动DRX-Retransmission Timer并接收基站重新传输的数据。
HARQ RTT Timer是终端设备等待下行数据重传之前所需要的最少的子帧数目。DRX-Retransmission Timer是指UE在等待HARQ重传时,所需要监听的最大的PDCCH的子帧数目。
上文结合图2至图4从终端设备的角度对本申请实施例的通信方法进行了详细的描述,下面结合图5从网络设备的角度对本申请实施例的通信方法进行详细的描述,应理解,图5中所示的通信方法与图2至图4中所示的通信方法是对应的,为了简洁,适当省略重复的描述。
图5是本申请实施例的通信方法的示意性流程图。图5的方法包括:
510、网络设备生成第一指示信息,所述第一指示信息用于所述终端设备从预先配置的多种DRX参数中确定与目标业务对应的DRX参数;
520、所述网络设备向所述终端设备发送第一指示信息。
现有技术中,终端设备只对应一套DRX参数,也就是说终端设备的不同的业务对应的都是同一套DRX参数,而不同业务类型的传输需求可能并不相同,不适合采用同一套DRX参数,而本申请中,能够确定每一种业务对应的DRX参数,与现有技术相比更加灵活。
可选地,上述第一指示信息指示所述目标业务对应的DRX参数。
具体地,上述第一指示信息可以具体指示目标业务对应的DRX参数在预先配置的多种DRX参数中的索引。
上述第一指示信息还可以具体指示目标业务对应的DRX参数的参数值。
可选地,上述第一指示信息指示目标业务对应的业务类型
可选地,在网络设备生成第一指示信息之前,图3的方法还包括:网络设备根据目标业务的业务类型,以及业务类型与DRX参数之间的对应关系,从预先配置的多种DRX参数中确定目标业务对应的DRX参数。
可选地,目标业务的业务类型信息包括目标业务的数据所属的逻辑信道标识或者逻辑信道组标识、目标业务的数据的服务质量分流标识,以及目标业务的数据所属的DRB中的至少一种。
可选地,上述第一指示信息承载在下行控制信息DCI或者媒体接入控制单元MAC CE中。
可选地,图5的方法还包括:网络设备为终端设备配置多种DRX参数。
