该无线通信***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***或网络还可以称为新无线(New Radio,NR)***或网络。
为了更好地理解本申请实施例的用于确定DRX状态的方法,下面先结合图2对DRX进行简单的介绍。如图2所示,一个完整的DRX周期由DRX激活期和DRX休眠期组成,当满足一定的触发条件时,终端设备进入DRX激活期,在DRX激活期中如果终端设备发起数据调度请求,那么就开启DRX非激活定时器(DRX-Inactivity Timer),如果在DRX非激活定时器的定时时间内终端设备没有接收到调度信息,那么在达到DRX非激活定时器的定时时间后终端设备就进入DRX休眠期,如果在DRX非激活定时器的定时时间内终端设备检测到调度信息,那么终端设备就可以重启DRX非激活定时器继续监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)。
应理解,在DRX激活期终端设备处于第一DRX状态,在DRX休眠期终端设备处于第二DRX状态。无论终端设备处于第一DRX状态还是处于第二DRX状态,终端设备与网络设备均处于RRC连接状态。当终端设备处于DRX第一DRX状态(此时终端设备处于DRX激活期)时终端设备打开接收机,监听物理下行控制信道(Physical Downlink Control Channel,PDCCH),当终端设备处于第二DRX状态(此时终端设备处于DRX休眠期)时,终端设备关闭接收机不再监听PDCCH。
在现有的长期演进(Long Term Evolution,LTE)LTE***中,网络设备通过RRC信令为终端设备静态配置DRX参数,这些DRX参数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)、DRX短周期定时器(DRX-Short Cycle Timer)、以及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)等等。
现有的静态配置DRX参数的方式非常不灵活,不能动态地调整为终端设备配置的DRX参数,进而灵活改变终端设备所处的DRX状态。
例如,当终端设备向网络设备发起数据调度请求后,DRX非激活定时器开启,终端设备开始监听PDCCH,当网络设备接收到终端设备的数据调度请求后,由于网络负载较重,终端设备在DRX非激活定时器的定时时间内无法调度终端设备,而在DRX非激活定时器启动后,终端设备需要一直处于监听状态直到DRX非激活定时器失效。也就是说,在DRX非激活定时器的定时时间内,网络设备并不调度终端设备,但是终端设备却一直处于监听状态,导致终端设备消耗的电能增加。
因此,本申请实施例提出了一种确定DRX状态的方法,通过动态的指示信息来指示终端设备灵活地切换终端设备所处的DRX状态或者改变终端设备所处的DRX状态的持续时间。下面结合图3和图4对本申请实施例的确定DRX状态的方法进行详细的介绍。
图3是本申请实施例的用于确定DRX状态的方法的示意性流程图。图3的方法包括:
310、终端设备接收网络设备发送的第一指示信息,该第一指示信息用于指示终端设备切换DRX状态或者用于指示终端设备处于DRX状态的时间。
上述第一指示信息可以指示终端设备将当前所处的DRX状态切换至另一种DRX状态,也可以指示终端设备处于当前所处的DRX状态的时间或者终端设备处于下一个DRX状态的时间。
可选地,如果终端设备当前处于第一DRX状态,那么第一指示信息可以指示终端设备从第一DRX状态切换到第二DRX状态,这样,当终端设备 在接收到第一指示信息后就从第一DRX状态切换到第二DRX状态。具体地,如果终端设备当前处于第一DRX状态,那么网络设备可以在网络负载较多或者该终端设备的优先级较低(例如,该终端设备为执行增强移动宽带业务的设备)的情况下生成上述第一指示信息,指示终端设备从第一DRX状态切换到第二DRX状态。
320、终端设备根据上述第一指示信息切换终端设备当前所处的DRX状态,或者,根据上述第一指示信息确定终端设备所处的DRX状态的时间,其中,终端设备当前所处的DRX状态为第一DRX状态或者第二DRX状态,在第一DRX状态下终端设备的接收机开启(监听PDCCH),在第二DRX状态下终端设备的接收机关闭(不监听PDCCH)。
本申请实施例中,通过第一指示信息能够动态地调整终端设备所处的DRX状态或者终端设备所处的DRX状态的时间,进而提高终端设备以DRX方式传输数据的效率,减少终端设备电能的消耗。
应理解,当上述第一指示信息用于指示终端设备处于DRX状态的时间时,该DRX状态可以是终端设备当前所处的DRX状态也可以是终端设备进行状态切换后所处的DRX状态。
可选地,终端设备当前所处的DRX状态为第一DRX状态,上述第一指示信息用于指示终端设备处于第一DRX状态的时间,当终端设备接收到该第一指示信息后就可以确定终端设备处于该第一DRX状态的时间。
通过第一指示信息可以重新为终端设备配置处于第一DRX状态的时间,也就是说通过第一指示信息能够动态调整终端设备处于第一DRX状态的时间,从而提高终端设备以DRX传输数据的效率。
例如,终端设备处于第一DRX状态,并且当前网络负载较多时,网络设备无法在在当前一段时间内调度终端设备,这时网络设备可以通过第一指示信息为第一DRX状态重新配置一个较短的时间使得终端设备能够快速从第一DRX状态切换到第二DRX状态,从而减少终端设备不必要的监听,减少电能的消耗。
可选地,上述第一指示信息用于指示终端设备处于第一DRX状态的时间时有多种可能的指示方式,这些指示方式至少包括以下几种:
(1)、第一指示信息具体用于指示所述第一DRX状态的持续时间为第一时间段。
例如,根据网络设备为终端设备预先配置的DRX参数,终端设备处于第一DRX状态的持续时间为30ms,并且,终端设备当前已经处于第一DRX状态的时间是10ms,第一指示信息指示第一DRX状态的持续时间为20ms,那么终端设备根据第一指示信息确定第一DRX状态的持续时间为20ms,而不是原来的30ms,也就是说从当前再经过10ms的时间终端设备就会从第一DRX状态切换到第二DRX状态。
(2)、第一指示信息具体用于指示第一DRX状态持续到第一时刻。
例如,当前时刻为第10ms,根据网络设备为终端设备预先配置的DRX参数,终端设备处于第一DRX状态的时间是从第0ms持续到第30ms,第一指示信息指示第一DRX状态持续到第20ms,那么终端设备在接收到第一指示信息后就可以确定第一DRX状态持续到第20ms,到了第20ms的终端设备就要从第一DRX状态切换到第二DRX状态。
可选地,终端设备当前所处的DRX状态为第一DRX状态,上述第一指示信息还可以指示终端设备处于第二DRX状态的时间,其中,该第二DRX状态为终端设备从第一DRX状态进行状态切换之后所处的DRX状态,在这种情况下,终端设备可以根据第一指示信息确定终端设备处于第二DRX状态的时间,也就是说终端设备可以根据第一指示信息确定处于下一个DRX状态的时间。
可选地,上述第一指示信息用于指示终端设备处于第二DRX状态的时间时有多种可能的指示方式,这些指示方式至少包括以下几种:
(3)、第一指示信息具体用于指示第二DRX状态的持续时间为第二时间段。
例如,终端设备经过一段时间之后将从当前所处的第一DRX状态切换到第二DRX状态,根据网络设备为终端设备配置的DRX参数,终端设备接下来将要处于第二DRX状态的持续时间为30ms,而第一指示信息指示终端设备接下来将要处于第二DRX状态的持续时间为20ms,那么,在接收到第一指示信息后,当终端设备切换到第二DRX状态之后在该状态下的持续时间就变成了20ms,这样就缩短了终端设备处于第二DRX状态的时间。
(4)、第一指示信息具体用于第二DRX状态持续到第二时刻。
例如,终端设备在第10ms时将从当前所处的第一DRX状态切换到第二DRX状态,根据网络设备为终端设备配置的DRX参数,终端设备将在第 10ms至第40ms之间处于第二DRX状态,而第一指示信息指示终端设备在切换到第二DRX状态保持该状态并持续到第30ms,那么,在接收到第一指示信息后,终端设备就将在第10ms至第30ms之间处于第二DRX状态,缩短了终端设备处于第二DRX状态的时间。
应理解,通过第一指示信息既可以缩短终端设备处于第一DRX状态或者第二DRX状态的时间,也可以延长终端设备处于第一DRX状态或者第二DRX状态的时间。
下面结合实例1和实例2对本申请确定DRX状态的方法进行详细的介绍:
实例1:
终端设备向网络设备发起数据调度请求后,DRX非激活定时器开启,终端设备开始监听PDCCH,网络设备接收到终端设备的数据调度请求后,由于网络负载较重,网络设备在DRX非激活定时器的定时时间内不能调度终端设备,因此,网络设备向终端设备发送指示信息,指示终端设备由DRX激活状态切换到DRX休眠状态,以减少电能的消耗。
实例2:
网络设备通过RRC信令为终端设备配置的HARQ RTT Timer为8个子帧长度。当需要快速反馈HARQ时,网络设备可以通过指示信息指示HARQ RTT Timer的持续时间为4个子帧,使得终端设备能够快速由DRX休眠状态切换到DRX激活状态以监听PDCCH;而不需要快速反馈HARQ时,网络设备可以通过指示信息指示HARQ RTT Timer的持续时间为12个子帧,使得终端设备在DRX休眠状态持续较长时间后再切换到DRX激活状态。
可选地,上述第一指示信息还可以承载在媒体接入控制单元MAC CE中。具体地,如表1所示,表1示出了逻辑信道ID字段标识对应的MAC业务数据单元(Service Data Unit,SDU)的逻辑信道实例以及相应的MAC控制单元或填充的类型。
上述第一指示信息可以承载表1所示的DRX命令(DRX Command)MAC CE、长DRX命令(Long DRX Command)MAC CE以及逻辑信道指示的预留(Reserved)MAC CE中的至少一个。
表1
Figure PCTCN2017070749-appb-000001
可选地,上述第一指示信息承载在下行控制信息(Downlink Control Information,DCI)上。
具体地,可以在DCI中通过增加一个新的域(DRX-Trigger)来表示上述第一指示信息,DRX-Trigger可以是1比特信息,0表示触发终端设备从第一DRX状态切换到第二DRX状态,1表示触发终端设备保持当前的第一DRX状态。
可选地,上述终端设备可以通过专属下行控制信道或者公共控制信道接收所述网络设备发送的第一指示信息。
可选地,网络设备可以预先为终端设备配置多个DRX参数,这时第一指示信息用于指示网路设备为所述终端设备动态配置的目标DRX参数,其中,该目标DRX参数用于指示终端设备处于DRX状态的时间。
上述第一指示信息指示目标DRX参数时有多种指示方式,例如,第一指示信息可以具体指示目标DRX参数在预先配置的多个DRX参数中的索引,第一指示信息还可以具体指示目标DRX参数的索引与第一DRX参数的索引的差值,其中,该第一DRX参数为预先配置的多个DRX参数中的任意一个DRX参数。优选地,上述第一DRX参数可以是网络设备通过RRC信令预先为终端设备配置的默认的DRX参数。
也就是说,第一指示信息可以通过直接指示的方式指示目标DRX参数的索引,也可以间接的指示该目标DRX参数的索引与某个DRX参数的索引的差值。
应理解,上述第一指示信息不仅可以直接通过第一指示信息本身来指示终端设备处于DRX状态的时间(此时第一指示信息指示的就是时间信息)。上述第一指示信息还可以间接通过指示目标DRX参数的方式来指示终端设备处于DRX状态的时间。
