(1)网络侧设备,是一种为所述终端提供无线通信功能的设备,包括但不限于:5G中的gNB、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(BaseBand Unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、移动交换中心等。本申请中的基站还可以是未来可能出现的其他通信系统中为所述终端提供无线通信功能的设备。

在长期演进(Long Term Evolution,LTE)系统中,用户设备之间允许进行直接通信。为了便于描述,定义用户设备之间的直接通信链路为Sidelink链路,其对应的无线接口称为直接通信接口(也称为Sidelink接口);网络侧设备与用户设备之间的蜂窝通信链路称之为Uu link链路,其对应的接口称为Uu接口。如图1所示,UE1和UE2之间通过Sidelink链路进行直接通信,UE1和UE2与网络侧设备之间通过Uu link链路进行通信。

具体的,第一终端获取所述网络侧设备发送的RRC信令或者MAC CE,所述RRC信令或者MAC CE中包括所述直通链路信道测量值。

方式一、获取直通链路信道测量值与非连续接收定时器(非连续接收(Discontinuous Reception,DRX)Timer)的时长之间的对应关系,之后,根据所述对应关系以及所述直通链路信道测量值,确定所述目标非连续接收定时器的时长。
其中,所述对应关系是网络侧设备配置的,或者,所述对应关系是预配置在所述第一终端中的。例如,网络侧设备可通过专用RRC信令或者广播RRC信令配置所述对应关系。
具体的,连接态的终端可以使用专用的RRC信令配置的所述直通链路信道测量值与非连续接收定时器的时长的对应关系,或使用广播RRC信令配置的所述直通链路信道测量值与非连续接收定时器的时长的对应关系,或使用预配置的所述直通链路信道测量值与非连续接收定时器的时长的对应关系;网络覆盖范围内的idle(空闲态)或inactive(非激活态)的终端,可以使用广播RRC信令配置的所述直通链路信道测量值与非连续接收定时器的时长的对应关系,或使用预配置的所述直通链路信道测量值与非连续接收定时器的时长的对应关系。网络覆盖范围外的终端,可以使用预配置的直通链路信道测量值与非连续接收定时器的时长的对应关系。
在本公开实施例中,所述直通链路信道测量值与非连续接收定时器的时 长的对应关系可以为表格,或为计算公式,或为索引等形式等,对此不做具体限定。
例如,直通链路信道测量值与非连续接收定时器的时长的对应关系可表示成如下表1所示。
表1
当直通链路信道测量值为CBR、CR、误码率、误块率时,可采用表1形式的对应关系,Timer3的值大于Timer2的值,Timer2的值大于Timer1的值,且Timer1、Timer2、Timer3均大于0。threshold 1小于threshold 2,且可根据实际需要设置。此时,直通链路信道测量值越大,对应的DRX Timer越大。例如CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的DRX timer时长等待接收数据。
当直通链路信道测量值为CSI、RI、CQI、SINR、RSRP、RSRQ、RSSI时,也可采用表1形式的对应关系,Timer3的值小于Timer2的值,Timer2的值小于Timer1的值,且Timer1、Timer2、Timer3均大于0。threshold 1小于threshold 2,且可根据实际需要设置。此时,直通链路信道测量值越大,对应的DRX Timer越小。例如CSI值越大,表明信道条件越好,DRX timer越小。
例如,在上表1中,经和threshold 1、threshold 2分别进行比较,如果某个直通链路信道测量值大于threshold 1但小于threshold 2,那么,对应的DRX Timer为Timer2。
方式二、获取直通链路信道测量值、QoS与非连续接收定时器的时长之间的对应关系,然后,根据所述对应关系、当前业务所需的QoS(Quality of Service,服务质量)以及所述直通链路信道测量值,确定所述目标非连续接收定时器的时长。
其中,所述对应关系是网络侧设备配置的,或者,所述对应关系是预配置在所述第一终端中的。例如,网络侧设备可通过专用RRC信令或者广播RRC信令配置所述对应关系。
这种方式中,上述对应关系可以理解为:在同一个直通链路信道测量值门限范围内基于不同的业务QoS参数而确定不同的DRX timer的时长,第一终端可以根据一定原则(比如当前业务的优先级、或者业务的时延需求等)选择合适的DRX timer的时长。例如,所述对应关系可以为表格,或为计算公式,或为索引等形式等,对此不做具体限定。
例如,所述直通链路信道测量值、QoS与非连续接收定时器的时长之间的对应关系如下表2-1所示。
表2-1
当直通链路信道测量值为CBR、CR、误码率、误块率时,可采用表2-1形式的对应关系,Timer6>Timer5>Timer4>Timer3>Timer2>Timer1,且Timer1~Timer6均大于0。threshold 1小于threshold 2,且可根据实际需要设置。优先级门限1或者时延门限1也可根据实际需要设置。此时,直通链路信道测量值越大,对应的DRX Timer越大。例如CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的DRX timer时长等待接收数据。业务越优先或者业务更重要,接收端可以选择更长的DRX timer时长等待接收数据。业务时延要求越低,接收端可以选择更短的DRX timer时长等待接收数据。
例如,在上表2-1中,经和threshold 1、threshold 2分别进行比较,如果某个直通链路信道测量值大于threshold 1但小于threshold 2,那么,对应的DRX Timer可能为Timer3或者Timer4;同时,又由于当前业务的优先级小于优先级门限1,那么,最终可确定对应的DRX Timer的时长为Timer3。
在上表2-1中,某个业务的优先级值越高表示其优先级越高,那么,对应的DRX timer时长更长。在实际应用中,也可规定优先级值越低表示其优先级越高,那么,对应的DRX timer时长更长。因此,上表2-1可变化成以下表2-2的形式。
表2-2
在上表2-2中,直通链路信道测量值小于或等于直通链路信道测量值threshold 1时,如果优先级值大于等于优先级门限1,对应的DRX timer时长为Timer1。
又例如,所述直通链路信道测量值、QoS与非连续接收定时器的时长之间的对应关系如下表2-3所示。
表2-3
当直通链路信道测量值为CSI、RI、CQI、SINR、RSRP、RSRQ、RSSI时,可采用表2-3形式的对应关系。
其中,Timer6<Timer5<Timer4<Timer3<Timer2<Timer1,且Timer1~Timer6均大于0。threshold 1小于threshold 2,且可根据实际需要设置。优先级门限 1或者时延门限1也可根据实际需要设置。此时,直通链路信道测量值越大,对应的DRX Timer越小。例如CSI值越大,表明信道条件越好,DRX timer越小。业务越优先或者业务更重要,接收端可以选择更长的timer时长等待接收数据。业务时延要求越低,接收端可以选择更短的timer时长等待接收数据。
在上表2-3中,优先级值越高表示其优先级越高,那么,对应的DRX timer时长更长。在实际应用中,也可规定优先级值越低表示其优先级越高,那么,对应的DRX timer时长更长。因此,上表2-3可变化成以下表2-4的形式。
表2-4
在上表2-4中,直通链路信道测量值小于或等于直通链路信道测量值threshold 1时,如果优先级值大于等于优先级门限1,对应的DRX timer时长为Timer1。
当然,对应关系中也可以规定每个业务优先级对应的timer时长,或者,也可以规定每个业务时延需求对应的timer时长。
当然,上述仅仅是举例说明不同方式下对应关系的不同形式,在具体实 施中,还可以有其他形式的对应关系,本公开实施例中对此不做限定。
在本公开实施例中,所述目标非连续接收定时器包括以下定时器中的一种或者多种:
On duration timer(激活定时器),Short DRX cycle Timer(短DRX周期定时器),Long DRX cycle Timer(长DRX周期定时器),Inactivity Timer(非激活定时器),回环时延(Round Trip Time,RTT)Timer,Retransmission Timer(重传定时器)。
对于不同的定时器,在本公开实施例中还可区分其定时器的时长。
例如,在本公开实施例中,可预设某种规则,根据直通链路信道测量值的不同,确定不同的定时器的时长。例如,可设置一种对应关系,当直通链路信道测量值位于不同的范围时,一种或者几种定时器的时长对应为某个值,或者,几种定时器的时长对应不同的值。也就是说,直通链路信道测量值位于某一个范围时,可确定一种定时器的时长,也可以确定多个定时器的时长,或者,即使直通链路信道测量值位于某一个范围时,不同的定时器也可具有不同的定时器时长。
例如,结合上述表1或者表2,当直通链路信道测量值小于或等于直通链路信道测量值threshold 1,On duration timer的时长为Timer1;当直通链路信道测量值大于或等于直通链路信道测量值threshold 1、但小于或等于直通链路信道测量值threshold 2时,Short DRX cycle Timer的时长为Timer2。
又例如,结合上述表1或者表2,当直通链路信道测量值小于或等于直通链路信道测量值threshold 1,On duration timer和Short DRX cycle Timer的时长为Timer1,或者On duration timer和Short DRX cycle Timer的时长分别为Timer1和Timer1’。
需要说明的是,区分不同定时器的时长的方式可结合对应关系一起配置,也可单独配置,本公开实施例中对其具体实现形式不做限定。
在本公开实施例中,第一终端可以根据直通链路信道测量值或者第二终端的指示信息确定目标非连续接收定时器的时长,从而可节省第一终端的功耗,并且不降低第一终端的通信可靠性。

在此实施例中,所述对应关系是网络侧设备配置的,或者,所述对应关系是预配置在所述第二终端中的。具体的,所述对应关系是所述网络侧设备通过专用RRC信令或者广播RRC信令配置的。
其中,所述直通链路信道测量值的含义可参照前述方法实施例的描述,目标非连续接收定时器的内容也可参照前述方法实施例的描述。
在本公开实施例中,第一终端可以根据直通链路信道测量值或者第二终端的指示信息确定目标非连续接收定时器的时长,从而可节省第一终端的功耗,并且不降低第一终端的通信可靠性。
参见图4,图4是本公开实施例提供的信息确定方法的流程图,应用于网络侧设备,如图4所示,包括以下步骤:
步骤401、向第一终端发送直通链路信道测量值,用于使得所述第一终端根据所述直通链路信道测量值确定目标非连续接收定时器的时长。
具体的,网络侧设备可向所述第一终端发送RRC信令或者MAC CE,所述RRC信令或者MAC CE中包括所述直通链路信道测量值。其中,RRC信令可以为专用的RRC信令或者广播RRC信令(如系统信息块(System Information Block,SIB))。进一步的,所述RRC信令或者MAC CE中还包括以下至少一项信息:源L2标识,目的L2标识,SLRB标识,LCID,用于指示所述直通链路信道测量值是第一终端和第二终端之间的直通链路信道测量值。
在本公开实施例中,所述直通链路信道测量值的内容可参照前述实施例的描述。
在实际应用中,网络侧设备可以是基站。网络侧设备指示的直通链路信道测量值可以是网络侧设备通过终端获得的,例如终端上报直通链路信道测量值给网络侧设备,网络侧设备将该服务小区内的直通链路信道测量值(或者是终端上报的直通链路信道测量值的统计平均值)指示给第一终端,用于第一终端确定目标非连续接收定时器的时长。例如,网络侧设备可获取覆盖范围内的任意终端上报的CBR、CR等并将其指示给第一终端,或者,网络侧设备获取第二终端上报的CSI、误码率、误块率、RI、CQI、SINR、RSRP、RSRQ、RSSI等,将其指示给第一终端。
此外,在上述实施例的基础上,为方便第一终端或者第二终端确定非连续接收定时器的时长,所述网络侧还可向第一终端和/或第二终端发送直通链路信道测量值与非连续接收定时器的时长之间的对应关系,或者,向第一终端和/或第二终端发送直通链路信道测量值、QoS与非连续接收定时器的时长之间的对应关系,还可向第一终端和/或第二终端发送上述两种对应关系。
也就是说,上述两种对应关系,网络侧设备可向第一终端和第二终端的一个或者两个发送其中的一种对应关系,也可向第一终端和第二终端的一个或者两个发送两种对应关系。
其中,所述对应关系是通过专用RRC信令或者广播RRC信令发送的。所述对应关系的实现方式可参照前述实施例的描述。
在本公开实施例中,第一终端可以根据直通链路信道测量值或者第二终端的指示信息确定目标非连续接收定时器的时长,从而可节省第一终端的功耗,并且不降低第一终端的通信可靠性。
相关技术中的NR V2X中,并没有DRX机制。对于V2X终端,尤其是P-UE,需要引入sidelink接口的DRX机制。对于sidelink接口mode 2,不同于Uu接口,终端需要在资源池中自主选择一个发送资源。如果附近区域中的终端较多,资源池的拥挤程度较高,终端可能选不到发送资源,而延迟发送,因此,接收终端的DRX timer设计需要和资源池的拥挤程度相关,从而调整Active time,节省功耗的同时,也不会丢失信息。
因此,在本公开实施例中,为解决上述问题,第一终端根据直通链路信道测量值或者第二终端的指示信息,确定DRX timer的时长。
其中,所述直通链路信道测量值与DRX timer的时长的对应关系是由网络侧设备配置,或预配置给第一终端或第二终端的。所述直通链路信道测量值可以是第一终端的直通链路信道测量值,或者是第二终端指示的直通链路信道测量值,或者是网络侧设备指示的直通链路信道测量值。
其中,第一终端通过直通链路与第二终端通信。例如,第一终端为发送终端,第二终端为接收终端,或者第一终端为接收终端,第二终端为发送终端。
以下,结合不同的实施例描述一下本公开实施例的实现过程。其中,第一终端为UE1,第二终端为UE2。
在图5所示的实施例中,第一终端根据第一终端的直通链路信道测量值,确定DRX timer的时长。
参见图5,图5是本公开实施例提供的信息确定方法的流程图,如图5所示,包括以下步骤:
步骤501、UE1对直通链路信道进行测量,得到直通链路信道测量值。
其中,所述直通链路信道测量值可包括信道状态信息、信道拥塞程度中的一种或者两种。

例如,以CBR和Retransmission Timer为例,CBR和Retransmission Timer的时长的对应关系可以如下表3-1所示:
表3-1
其中,Timer3的时长大于Timer2的时长,Timer2的时长大于Timer1的时长。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer(定时器)时长等待混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程的重传。其中,CBR threshold 1小于CBR threshold 2。
例如,对于步骤401得到的CBR值,通过查找表3-1,确定CBR小于或等于CBR threshold 1,那么,Retransmission Timer的时长为Timer1。
又例如,以CBR和Retransmission Timer为例,CBR、QoS和Retransmission Timer的时长的对应关系可以如下表3-2所示:
表3-2
其中,Timer1<Timer2<Timer3<Timer4<Timer5<Timer6。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer(定时器)时长等待HARQ进程的重传。其中,CBR threshold 1小于CBR threshold 2。
例如,对于步骤501得到的CBR值,通过查找表3-2,确定CBR小于或等于CBR threshold 1,Qos大于或等于优先级门限1,那么,Retransmission Timer的时长为Timer2。
又例如,以CBR和Retransmission Timer为例,CBR、QoS和Retransmission Timer的时长的对应关系可以如下表3-3所示:
表3-3
其中,Timer1<Timer2<Timer3<Timer4<Timer5<Timer6。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer(定时器)时长等待HARQ进程的重传。其中,CBR threshold 1小于CBR threshold 2。
例如,对于步骤501得到的CBR值,通过查找表3-2,确定CBR小于或等于CBR threshold 1,Qos大于或等于优先级门限1,那么,Retransmission Timer的时长为Timer1。
例如,对于步骤501得到的CBR值,通过查找表3-2,确定CBR小于或等于CBR threshold 1,Qos小于优先级门限1,那么,Retransmission Timer的时长为Timer2。

在图6所示的实施例中,第一终端根据第二终端的直通链路信道测量值,确定DRX timer的时长。
参见图6,图6是本公开实施例提供的信息确定方法的流程图,如图6所示,包括以下步骤:
步骤601、UE2对直通链路信道进行测量,得到直通链路信道测量值。
其中,所述直通链路信道测量值可包括信道状态信息、信道拥塞程度中的一种或者两种。
具体的,UE2可以根据UE1发送的参考信号(如SRS)或数据信息,对直通链路信道进行测量,从而得到信道状态信息,例如,CSI,RI,CQI,SINR,RSRP,RSRQ,RSSI,误块率、误码率等。或者,UE2可以对直通链路信道进行测量统计,从而得到信道拥塞程度,例如,CBR,CR等。
步骤602、UE2使用SL RRC或者SL MAC CE向UE1发送直通链路信道测量值。
步骤603、UE1根据该直通链路信道测量值确定DRX timer的时长。
在本公开实施例中,所述DRX timer可以为如下timer中的一种或多种:
On duration timer,Short DRX cycle Timer,Long DRX cycle Timer,Inactivity Timer,RTT Timer,Retransmission Timer。
以CBR和Retransmission Timer为例,CBR和Retransmission Timer的时长的对应关系可以如下表4所示:
表4
其中,Timer3的时长大于Timer2的时长,Timer2的时长大于Timer1的时长。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer时长等待HARQ进程的重传。
例如,对于步骤602得到的CBR值,通过查找表4,确定CBR小于或等于CBR threshold 1,那么,Retransmission Timer的时长为Timer1。
在本公开实施例中,UE1还可根据CBR、QoS和Retransmission Timer的时长的对应关系确定CBR为某个具体的取值时Retransmission Timer的时长。 此时,UE1确定的方式可参照图5所示的实施例中步骤502中的相关描述。
步骤604、UE2向UE1发送数据信息。
步骤605、UE1在DRX timer的时长确定的active time接收第二终端发送的数据信息。

在图7所示的实施例中,第一终端根据第二终端的指示信息确定DRX timer的时长。
参见图7,图7是本公开实施例提供的信息确定方法的流程图,如图7所示,包括以下步骤:
步骤701、UE2对直通链路信道进行测量,得到直通链路信道测量值。
其中,所述直通链路信道测量值可包括信道状态信息、信道拥塞程度中的一种或者两种。
具体的,UE2可以根据UE1发送的参考信号(如SRS)或数据信息,对直通链路信道进行测量,从而得到信道状态信息,例如,CSI,RI,CQI,SINR,RSRP,RSRQ,RSSI,误块率、误码率等。或者,UE2可以对直通链路信道进行测量统计,从而得到信道拥塞程度,例如,CBR,CR等。
步骤702、UE2根据该直通链路信道测量值确定DRX timer的时长。
在本公开实施例中,所述DRX timer可以为如下timer中的一种或多种:
On duration timer,Short DRX cycle Timer,Long DRX cycle Timer,Inactivity Timer,RTT Timer,Retransmission Timer。
以CBR和Retransmission Timer为例,CBR和Retransmission Timer的时长的对应关系可以如下表5所示:
表5
其中,Timer3的时长大于Timer2的时长,Timer2的时长大于Timer1的时长。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer时长等待HARQ进程的重传。
例如,对于步骤701得到的CBR值,通过查找表5,确定CBR大于或等于CBR threshold 1,但小于或等于CBR threshold 2,那么,Retransmission Timer的时长为Timer2。
在本公开实施例中,UE2还可根据CBR、QoS和Retransmission Timer的时长的对应关系确定CBR为某个具体的取值时Retransmission Timer的时长。此时,UE2确定的方式可参照图5所示的实施例中步骤502中的相关描述。
步骤703、向UE1发送DRX timer的时长。
第二终端可以根据上述表格和步骤7701中的信道测量值确定Retransmission Timer的时长,例如,Timer1,然后将Timer1通过SL RRC或者SL MAC CE指示给第一终端。

步骤705、UE1在DRX timer的时长确定的active time接收第二终端发送的数据信息。
如果HARQ进程中的数据解码不成功,在RTT Timer超时后,UE启动Retransmission Timer。在Retransmission Timer期间,UE监听控制信令,等待对应HARQ进程的重传数据信息。
在图8所示的实施例中,第一终端根据网络侧设备(如基站)指示的直通链路信道测量值,确定DRX timer的时长。
参见图8,图8是本公开实施例提供的信息确定方法的流程图,如图8所示,包括以下步骤:
步骤801、网络侧设备使用RRC或者MAC CE向UE1发送直通链路信道测量值。
该直通链路信道测量值可以为:信道状态信息,例如,CSI,RI,CQI,SINR,RSRP,RSRQ,RSSI,误块率、误码率等中的一种或多种,或者可以为信道拥塞程度,例如,CBR,CR等中的一种或多种。
步骤802、UE1根据该直通链路信道测量值确定DRX timer的时长。
在本公开实施例中,所述DRX timer可以为如下timer中的一种或多种:

以CBR和Retransmission Timer为例,CBR和Retransmission Timer的时长的对应关系可以如下表6所示:
表6
其中,Timer3的时长大于Timer2的时长,Timer2的时长大于Timer1的时长。即,CBR越高,信道越拥塞,则可供终端选择的发送资源越少,接收端需要更长的timer时长等待HARQ进程的重传。
例如,对于步骤801得到的CBR值,通过查找表6,确定CBR大于CBR threshold2,那么,Retransmission Timer的时长为Timer3。
在本公开实施例中,UE1还可根据CBR、QoS和Retransmission Timer的时长的对应关系确定CBR为某个具体的取值时Retransmission Timer的时长。此时,UE1确定的方式可参照图5所示的实施例中步骤502中的相关描述。
