图2为本申请实施例提供的启动定时器的方法的流程示意图,如图2所示,所述启动定时器的方法包括以下步骤:
步骤201:终端接收控制信令,如果所述控制信令指示有数据传输的调度以及将第一带宽部分BWP切换到第二BWP,则所述终端启动第一定时器。
本申请实施例中,所述终端可以是手机、平板电脑、车载终端、笔记本、可穿戴 式设备等任意能够与网络进行通信的设备。
本申请实施例中,所述终端被网络配置有至少两个BWP,分别为第一BWP和第二BWP,终端可以在将第一BWP作为工作带宽,也可以将第二BWP作为工作带宽,第一BWP和第二BWP至少具有不同的带宽大小、和/或不同的带宽位置、和/或不同的子载波间隔(SCS,Subcarrier Spacing)。
假设终端当前的工作带宽为第一BWP,网络侧可以向终端发送一个指示信息,来指示终端将第一BWP切换到第二BWP。具体实现时,该指示信息可以通过承载在下行控制信道(PDCCH,Physical Downlink Control Channel)中的控制信令来实现,进一步,所述控制信令为下行控制信息(DCI,Downlink Control Information)。
本申请实施例中,MAC协议定义了第一定时器,以下对第一定时器的具体实现方式进行描述。
实现方式一:所述第一定时器用于所述终端在所述第一定时器运行期间监听PDCCH。
举个例子:在非连续接收(DRX,Discontinuous Reception)中,所述第一定时器为DRX-inactivityTimer,在DRX-inactivityTimer运行期间,终端的MAC实体处于DRX激活时间,MAC实体在DRX激活时间监听PDCCH,这里,终端监听的PDCCH由一些无线网络临时标识(RNTI,Radio Network Tempory Identity)加扰。需要说明的是,DRX-inactivityTimer由某些事件触发,比如收到PDCCH(该PDCCH调度新传数据)时,DRX-inactivityTimer就会启动或者重启。
一个DRX周期包括两个时间段,一个是DRX激活时间,另一个是DRX非激活时间。DRX-inactivityTimer运行的时间段属于DRX激活时间。
实现方式二:所述第一定时器用于所述终端在所述第一定时器运行期间不在第一混合自动重传请求(HARQ,Hybrid Automatic Repeat reQuest)进程对应的上行资源上传输第一数据(第一数据是新传数据),所述第一HARQ进程与所述第一定时器具有对应关系,所述第一数据是除第二数据以外的数据,所述第二数据是占用所述第一HARQ进程的数据。
这里,第一HARQ进程对应的上行资源是上行配置资源,这个上行资源是半静态配置的,包含以下两种类型:
Type1configured grant:由RRC配置,配置之后就激活;
Type2configured grant:由RRC配置,但是配置之后需要DCI信令激活,激活之 后才开始使用。
举个例子:在HARQ中,所述第一定时器为configuredGrantTimer,该configuredGrantTimer是针对某个HARQ进程(本申请实施例称为第一HARQ进程)配置的,并且,该HARQ进程具有对应的上行资源(称为configuredGrant),在configuredGrantTimer运行期间,configuredGrant仅限于该HARQ进程占用,终端不会在与该HARQ进程对应的configured grant上新传数据(新传数据可以是上行数据和/或下行数据)。
本申请实施例中,网络侧可以向终端发送一个指示信息,来指示有数据传输的调度,进一步,该指示信息用于指示有新传数据的调度(新传数据可以是上行数据和/或下行数据)。具体实现时,该指示信息可以通过承载在PDCCH中的控制信令来实现,进一步,所述控制信令为DCI。
在一实施方式中,指示有数据传输的调度的控制信令与指示将第一BWP切换到第二BWP的控制信令为同一控制信令,例如:网络侧向终端发送PDCCH,该PDCCH中的DCI指示有新传数据的调度的同时,还指示从第一BWP切换到第二BWP,从而使得终端从第一BWP切换到第二BWP后,在第二BWP上实现新数据的传输。
在另一实施方式中,指示有数据传输的调度的控制信令与指示将第一BWP切换到第二BWP的控制信令为不同的控制信令。例如:网络侧向终端发送第一DCI和第二DCI,第一DCI指示有新传数据的调度,第二DCI指示从第一BWP切换到第二BWP。
本申请实施例中,如果所述终端接收到的控制信令既指示了有数据传输的调度,又指示了将第一BWP切换到第二BWP,则所述终端启动所述第一定时器,使得所述第一定时器的超时时刻在BWP切换成功之后,从而实现第一定时器相应的功能。需要说明的是,所述终端在接收到所述控制信令的时刻开始执行从第一BWP到第二BWP的切换。进一步,所述终端在BWP切换过程中启动第一定时器的方式可以具有如下几种:
方式一:所述终端在所述控制信令收到之后的第一个时域符号上启动所述第一定时器。其中,所述第一定时器的时长是网络配置的第一时长。
进一步,所述第一定时器超时时,如果所述终端未完成从所述第一BWP到所述第二BWP的切换,则所述终端重启所述第一定时器。其中,重启的所述第一定时器的时长由网络配置;或者,重启的所述第一定时器的时长为从所述第一BWP到所述 第二BWP的切换时延;或者,重启的所述第一定时器的时长为规定的BWP最小切换时延。
其中,所述规定的BWP最小切换时延由所述终端的能力确定。
举个例子:终端在t1时刻接收到PDCCH,该PDCCH中的DCI用于指示有新传数据的调度,以及指示从BWP#1切换到BWP#2,终端从t1时刻开始执行BWP的切换过程,在t2时刻完成BWP的切换过程,BWP切换时延为t2-t1,终端在t1时刻之后的第一个正交频分复用(OFDM,Orthogonal Frequency Division Multiplexing)符号上启动第一定时器,该第一定时器的时长由网络配置为T1,第一定时器按照T1运行时,其超时时刻有两种情况,一种是位于BWP切换过程中,参照图3(b);另一种是位于BWP切换结束后,参照图3(a)。对于图3(b)的情况,第一定时器超时时,终端重启第一定时器,重启的第一定时器的时长为T2(T2与T1可以相等,也可以不等),T2可以由网络配置,或者等于BWP切换时延,或者等于38.133规定的BWP最小切换时延,使得重启的第一定时器的超时时刻位于BWP切换结束后。需要说明的是,如果第一定时器重启之后,第一定时器的超时时刻仍然在切换时延之内,则继续再重启第一定时器,直到第一定时器的超时时刻在成功切换之后。
进一步,所述第一定时器超时时,如果所述终端未完成从所述第一BWP到所述第二BWP的切换,则:
1)所述终端从所述第一BWP切换到默认BWP上;或者,2)所述终端从所述第一BWP切换到所述第二BWP上,并在所述第二BWP上重启所述第一定时器。
参照图3(e),所述终端在PDCCH收到之后的第一个时域符号上启动所述第一定时器,所述第一定时器在所述第一BWP到所述第二BWP的切换时延中超时,其中,所述PDCCH用于指示待切换的所述第二BWP。终端可以选择1):切换到初始/默认BWP上;或者,2)切换到PDCCH指示的BWP#2上,然后,在该BWP#2上重启第一定时器。需要说明的是,该第一定时器可以是bwp-InactivityTimer。
参照图3(f),所述终端在PDCCH收到之后的第一个时域符号上启动所述第一定时器,所述第一定时器在所述第一BWP到所述第二BWP的切换时延中超时,其中,所述PDCCH用于调度RRC消息,所述RRC消息用于指示待切换的所述第二BWP。终端可以选择1):切换到初始/默认BWP上;或者,2)切换到RRC消息指示的BWP#2上,然后,在该BWP#2上重启第一定时器。需要说明的是,该第一定时器可以是bwp-InactivityTimer。
方式二:所述终端在所述控制信令收到之后的第一个时域符号上启动所述第一定时器。其中,所述第一定时器的时长基于网络配置的第一时长、以及第二时长确定。具体地,所述第一定时器的时长是所述第一时长加上所述第二时长。
其中,所述第二时长由网络配置;或者,所述第二时长为从所述第一BWP到所述第二BWP的切换时延;或者,所述第二时长为规定的BWP最小切换时延。
其中,所述规定的BWP最小切换时延由所述终端的能力确定。
举个例子:终端在t1时刻接收到PDCCH,该PDCCH中的DCI用于指示有新传数据的调度,以及指示从BWP#1切换到BWP#2,终端从t1时刻开始执行BWP的切换过程,在t2时刻完成BWP的切换过程,BWP切换时延为t2-t1,终端在t1时刻之后的第一个OFDM符号上启动第一定时器,该第一定时器的时长由网络配置的T1和另一个延迟时长T3确定,例如:第一定时器的时长等于T1+T3,参照图3(c),其中,T3可以由网络配置,或者等于BWP切换时延,或者等于38.133规定的BWP最小切换时延,使得第一定时器的超时时刻位于BWP切换结束后。
上述方案中,38.133规定的BWP最小切换时延由终端的能力决定,可以取最大值,也可以由网络和终端根据能力来决定。
方式三:所述终端在所述控制信令收到之后的第一时间启动所述第一定时器,其中,所述第一时间与所述控制信令的接收时间具有第一时间偏移。其中,所述第一定时器的时长是网络配置的第一时长。
具体地,所述第一时间偏移为所述第一BWP到所述第二BWP的切换时延;或者,所述第一时间偏移为规定的BWP最小切换时延。其中,所述第一时间偏移由网络配置;或者,所述第一时间偏移由协议约定。
举个例子:终端在t1时刻接收到PDCCH,该PDCCH中的DCI用于指示有新传数据的调度,以及指示从BWP#1切换到BWP#2,终端从t1时刻开始执行BWP的切换过程,在t2时刻完成BWP的切换过程,BWP切换时延为t2-t1,终端在t1时刻之后延长一个T(offset)时长后,启动第一定时器,参照图3(d),T(offset)等于BWP切换时延,或者等于38.133规定的BWP最小切换时延,使得第一定时器的超时时刻位于BWP切换结束后。
本申请实施例中,所述方法还包括:如果所述控制信令未指示将第一BWP切换到第二BWP,则所述终端启动第二定时器。
具体实现时,所述终端在所述控制信令收到之后的第一个时域符号上启动所述第 二定时器。本申请实施例中,所述第二定时器和所述第一定时器可以为同一定时器。第二定时器的时长可以为网络配置的时长。
需要说明的是,本申请实施例的上述技术方案实现在终端的MAC层,通过终端的MAC实体来执行上述技术方案。
