Description

低功耗唤醒信号的监听方法、控制参数的配置方法和相关装置
本申请要求于2024年03月28日提交中国专利局、申请号为202410372589.1、发明名称为“低功耗唤醒信号的监听方法、控制参数的配置方法和相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种低功耗唤醒信号的监听方法、低功耗唤醒信号的控制参数的配置方法、电子设备、计算机程序产品以及计算机可读存储介质。
背景技术
在一些通信系统中,网络设备经由下行链路信道来寻呼用户设备(user equipment,UE)或者向UE发送广播消息。为了检测潜在寻呼消息或广播消息,UE可以利用主接收机(main radio,MR)持续地监测下行链路信道。为了降低UE的功耗,UE配置低功耗唤醒接收机(low power receiver,LR),相应地,网络设备向UE发送唤醒信号。在UE处于唤醒信号的覆盖范围内,MR被关闭,UE处于睡眠状态,由LR接收唤醒信号。在LR接收到唤醒信号之后,将UE从睡眠状态唤醒且唤醒MR来接收寻呼消息或广播消息。
目前,协议规定了UE进入唤醒信号的覆盖范围可以由进入门限值来规定,UE离开唤醒信号的覆盖范围可以由退出门限值来规定。假设进入门限值和退出门限值相同,UE处在唤醒信号的覆盖范围边界且来回变动时,UE将不可避免的频繁的打开和关闭MR。然而,频繁打开关闭MR会导致UE的硬件设备的寿命受损,且产生不必要的功耗。

本申请实施例涉及的多个,是指大于或等于两个。需要说明的是,在本申请实施例的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。
本申请实施例提供的技术方案可应用于通信系统,该通信系统可以是第二代(2G)通信系统、第三代(3G)通信系统,可以是LTE系统,也可以是第五代(5G)通信系统,还可以是LTE与5G混合架构、也可以是5G新无线(5G New Radio,5G NR)系统,以及未来通信发展中出现的新通信系统等。
通信系统包括第一设备和第二设备。第一设备可以是网络侧用于提供网络通信功能的设备,有些情况下也称作网络设备、网元,网络设备通常可以是基站(包括基站的功能单元,或者基站的功能单元的组合)或者是核心网单元,其中,核心网单元可以是核心网中的功能单元,包括但不限于接入和移动性管理功能(access and mobility management function,AMF)单元或会话管理功能(session management function,SMF)单元。第二设备可以是接入网络的设备,通常可以为终端。通信系统的一种示例如图1所示,图1中包括基站100与终端200。
在本申请实施例中,基站100可以是具有无线收发功能的任意一种设备,包括但不限于:长期演进(long term evolution,LTE)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),新无线(new radio,NR)中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point,TRP),3GPP后续演进的基站,Wi-Fi系统中的接入节点,无线中继节点,无线回传节点等。基站可以是:宏基站,微基站,微微基站,小站,中继站,或气球站等。基站可以包含一个或多个共站或非共站的传输点(Transmission Reception Point,TRP)。基站还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器、集中单元(centralized unit,CU),和/或分布单元(distributed unit,DU)。基站可以与终端200进行通信,也可以通过中继站与终端200进行通信。终端200可以与不同技术的多个基站进行通信,例如,终端可以与支持LTE网络的基站通信,也可以与支持5G网络的基站通信,还可以与支持LTE网络的基站以及5G网络的基站进行双连接。
在本申请实施例中,终端200可以是各种形式,例如,手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。终端有时也可以称为终端设备、用户设备(user equipment,UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定终端或者移动终端。
在一些通信系统中,基站可以经由下行链路信道(例如,物理下行链路控制信道(PDCCH)或窄带PDCCH(NPDCCH))来寻呼UE,以指示数据和/或控制信息可用于UE。为了检测潜在寻呼消息,UE可以持续地监测下行链路信道。然而,为了降低UE处的功耗,可能期望仅在下行链路信道的某些时频资源期间针对寻呼消息进行监测。相应地,基站可以向UE发送低功耗唤醒信号(LP-WUS,low power-wake up signal),简称唤醒信号(WUS,wake up signal),以便将UE从睡眠状态唤醒并且向UE指示在对应的寻呼时机期间针对寻呼消息来监测下行链路信道。如果UE没有接收到WUS,则在下行链路信道中可能不存在针对UE的寻呼消息,并且UE可以保持在睡眠状态中(例如,直到基站重传WUS为止)。
并且,UE设置有主接收机(main radio,MR)以接收基站发送的寻呼消息或其他广播消息等,还设置有低功耗接收机(low power receiver,LR),也称为低功耗唤醒接收机(LP-WUR,low power-wake up receiver)或者辅助接收机。LP的功耗远远小于MR。当基站向UE发送唤醒信号,以唤醒MR睡眠的终端,因MR睡眠,UE使用LP来接收唤醒信号,收到唤醒信号后可以唤醒MR以进行数据收发操作等。另,UE还引入了低功耗同步信号(LP-SS,synchronization signals)进行同步。
示例性的,如图2中(a)所示,UE200沿靠近基站100的方向移动,开始进入基站100发送的唤醒信号的覆盖范围时,UE关闭MR,打开LR,由LR来接收基站100发送的唤醒信号。如图2中(b)所示,UE200沿远离基站100的方向移动,开始离开基站100发送的唤醒信号的覆盖范围时,UE可打开MR,由MR接收寻呼消息。UE可维持LR开启状态或者关闭LR。协议规定了UE200进入唤醒信号的覆盖范围可以由进入门限值来规定,UE离开唤醒信号的覆盖范围可以由退出门限值来规定。现需要对进入门限值和退出门限值的关系进行讨论。
一些实施例中,进入门限值和退出门限值可以称为目标参考信号质量的门限值,进入门限值和退出门限值可以为同一值或者为不同值。进入门限值和退出门限值可以为参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal receiving quality,RSRQ)等参数的门限值。
进入门限值和退出门限值为不同值,可以称为进入门限值和退出门限值等价,可以理解成:进入门限值和退出门限值也可以为RSRP或RSRQ等目标参考信号质量的门限值,但受限于UE进入和离开唤醒信号的覆盖范围,由不同硬件监测RSRP或RSRQ等目标参考信号质量,进入门限值和退出门限值会有所差异,但两者之间具有映射关系,该映射关系能够指示出进入门限值和退出门限值为相同值。示例性的,图2中(a)展示的进入门限值为RSRP_entry,可以理解成为MR监测的RSRP的门限值,退出门限值为LR-RSRP_exit,可以理解成由LR监测的RSRP的门限值。
以下以进入门限值为RSRP_entry,退出门限值为LR-RSRP_exit为示例进行介绍,但这并不构成对目标参考信号质量的门限值的限定。
在一种情况下,假设RSRP_entry<LR-RSRP_exit,如图3中(a)所示,UE200处于唤醒信号的覆盖范围内,MR被关闭;UE沿远离基站100的方向移动,离开唤醒信号的覆盖范围,且监测的RSRP值小于LR-RSRP_exit且大于RSRP_entry,但MR还处于关闭状态,会导致出现在唤醒信号的覆盖范围外接收唤醒信号,进而导致出现丢失寻呼消息的问题。
在另一种情况下,假设RSRP_entry=LP-RSRP_exit,UE处在唤醒信号的覆盖范围边界且来回变动,UE将不可避免的频繁的在1.打开MR和关闭LR,以及2.关闭MR和打开LR之间切换。频繁打开关闭MR存有以下问题:
1、UE打开MR会涉及UE的其他硬件,而这些硬件都有读写寿命,频繁的打开关闭MR会导致这些硬件的寿命缩减。
2、频繁的打开关闭MR,会产生不必要的功耗。
如图4中(a)所示,UE处于唤醒信号的覆盖范围外,MR处于开启状态,间断性监听基站下发的寻呼消息、广播消息等。经检测:MR的一次监听和服务小区的测量功耗为300。如图4中(b)所示,UE在唤醒信号的覆盖范围边缘进出一次,在UE满足进入唤醒信号的覆盖范围的条件时,MR被关闭,LR被开启,检测其功耗为5,UE又离开唤醒信号覆盖范围,MR被开启,经检测:MR被开启的功耗为15000~40000,且MR被开启,还需要进行一次同步,该同步的功耗为1000~3000。如此发现:MR开启+同步能耗是MR监听功耗的5~8倍。
为避免上述两个问题,本申请实施例提供了一种低功耗唤醒信号的监听方法。为了使得本申请实施例的技术方案更加清楚、易于理解,下面结合附图,对本申请实施例提供的低功耗唤醒信号的监听方法进行介绍。
参见图5所示的一种低功耗唤醒信号的监听方法的流程图,该方法中,基站100向UE200配置目标参考信号质量的门限值和迟滞时长,目标参考信号质量的门限值和迟滞时长为唤醒信号的控制参数,用于在UE200通过目标参考信号的门限值确定自身进入唤醒信号的覆盖范围之后,延迟迟滞时长后利用LR监听唤醒信号和关闭MR。如图5所示,该方法包括:
S501、基站100向UE200配置目标参考信号质量的门限值和迟滞时长。
UE驻留服务小区时,服务小区对应的基站向UE配置目标参考信号质量的门限值和迟滞时长;其中,服务小区是指为UE提供服务的小区。UE可能会连接到一个或多个小区,但只有一个被指定为服务小区,即主要提供通信服务的小区。
目标参考信号质量的门限值属于利用LR监听唤醒信号和控制UE开启,或停止利用LR监听唤醒信号和关闭MR的门限值,UE监测的目标参考信号质量大于目标参考信号质量的门限值,说明UE进入唤醒信号的覆盖范围,UE则关闭MR,还可以控制LR监听唤醒信号;UE监测的目标参考信号质量小于目标参考信号质量的门限值,则说明UE离开唤醒信号的覆盖范围,UE则开启MR,停止利用LR监听唤醒信号。
一些实施例中,在UE停止利用LR监听唤醒信号的情况下,UE可关闭LR或维持LR开启,因LR运行功耗较低。因此,目标参考信号质量的门限值也可以理解成用于指示UE是否进入或离开唤醒信号的覆盖范围,或者理解成用于控制接收或不接收唤醒信号。
在一些实施例中,目标参考信号质量的门限值为一个,UE通过该门限值来检测自身是否进入唤醒信号的覆盖范围,以及检测自身是否离开唤醒信号的覆盖范围。
在另一些实施例中,目标参数信号质量的门限值包括进入门限值和退出门限值,示例性的,目标参数信号质量的门限值为RSRP的门限值时,进入门限值称呼为RSRP_entry,退出门限值为LR-RSRP_exit,进入门限值和退出门限值相同,或者等价(可以理解成具有映射关系),可参见前述内容。
迟滞时长可以是以秒或毫秒为单位的正整数,示例性的,0~30s中的一个数值。迟滞时长属于控制在UE监测的目标参考信号质量小于目标参考信号质量的门限值时,延迟关闭MR的延迟时长。
在一些实施例中,基站100向UE200发送广播消息,广播消息用于指示目标参考信号质量的门限值和迟滞时长,其中,广播消息指示目标参考信号质量的门限值和迟滞时长的一种实现方式可以是:消息携带目标参考信号质量的门限值和迟滞时长。一些实施例中,基站100向UE200发送的广播消息可指代系统信息广播SIB,由SIB指示目标参考信号质量的门限值和迟滞时长,该SIB可为SIB1、SIB2等,并无具体限制。
在一些实施例中,基站100可以通过UE200发送不同的广播消息,来分别指示目标参考信号质量的门限值和迟滞时长,也可以发送一个广播消息来指示目标参考信号质量的门限值和迟滞时长。
基站100向UE200配置目标参数信号质量的门限值和迟滞时长之后,UE100可基于目标参数信号质量的门限值和迟滞时长,利用LR监听低功耗唤醒信号和关闭MR,或者停止利用LR监听低功耗唤醒信号和开启MR。下述步骤S502至步骤S508提供了一种实现方式。
S502、UE200获取目标参考信号质量的门限值和迟滞时长。
S503、UE200判断目标参考信号质量是否不小于目标参考信号质量的门限值。
UE200可间断性监测基站100的目标参考信号质量,并获取目标参考信号质量的门限值和迟滞时长,UE200将监测得到的目标参考信号质量和目标参考信号质量的门限值进行比对,以判断目标参考信号质量是否大于或等于目标参考信号质量的门限值。
其中,UE200判断目标参考信号质量大于或等于目标参考信号质量的门限值,则执行步骤S505,反之则执行步骤S504。
一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,UE200判断目标参考信号质量不小于目标参考信号质量的门限值则可指代是否不小于进入门限值。
S504、UE200维持MR开启状态。
UE200判断目标参考信号质量小于目标参考信号质量的门限值,说明UE200还处于唤醒信号的覆盖范围之外,UE200可维持MR处于开启状态,由MR监听UE100的寻呼消息或广播消息等。
S505、UE200不利用LR监听唤醒信号,维持MR开启状态,启动定时器。
结合图6所示,UE200处于唤醒信号的覆盖范围外,且在t0进入到覆盖范围,UE监测的目标参考信号质量等于或大于目标参考信号质量的门限值。通常情况下,UE200进入到唤醒信号的覆盖范围,UE200应关闭MR,由LR监听唤醒信号。但如前述内容,若UE200进入唤醒信号的覆盖范围之后,再反复进出唤醒信号的覆盖范围则会存在上述两个问题。基于此,UE200监测到目标参考信号质量小于目标参考信号质量的门限值之后,首次监测到目标参考信号质量不小于目标参考信号质量的门限值,先不关闭MR,且不利用LR监听唤醒信号,维持MR处于开启状态,还启动定时器,该定时器的定时时长则为迟滞时长。
需要说明的是,UE200启动定时器可以理解成是对进入唤醒信号的覆盖范围的时长进行计时,与确定是否达到迟滞时长。
S506、UE200判断定时器的计时时长是否达到迟滞时长。
定时器被启动之后,UE200则可判断定时器的计时时长是否达到迟滞时长,UE200判断出定时器的计时时长达到迟滞时长,则执行步骤S508,反之执行步骤S507。
S507、UE200判断目标参考信号质量是否大于目标参考信号质量的门限值。
UE200判断定时器的计时时长没有达到迟滞时长,则通过步骤S507判断在目标参考信号质量是否大于目标参考信号质量的门限值,若判断目标参考信号质量不大于目标参考信号质量的门限值,则说明UE200从唤醒信号的覆盖范围离开,可执行步骤S508。若判断目标参考信号质量大于目标参考信号质量的门限值,说明UE200持续位于唤醒信号的覆盖范围内,则返回执行步骤S506。
在一些实施例中,步骤S506和步骤S507可以是并行执行,并无图5展示的先后顺序的限制。
在一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,步骤S507可以理解成UE200判断目标参考信号质量是否小于退出门限值。其中,小于退出门限值则执行S508,反之则执行步骤S506。
S508、UE200不利用LR监听唤醒信号,维持MR开启状态,关闭定时器。
结合图6所示,UE200在t0进入到唤醒信号的覆盖范围之后,在t1时刻又离开覆盖范围,UE200则会监测到目标参考信号质量不大于目标参考信号质量的门限值,UE200则停止定时器,停止定时器还需要将定时器的计时清零。
步骤S508之后,UE200则返回到步骤S503,以重新监测目标参考信号质量,以通过目标参考信号质量是否不小于与目标参考信号质量的门限值这一评判标准,来确定UE200是否进入到唤醒信号的覆盖范围。
同样结合图6所示,UE200在t2时刻又进入到唤醒信号的覆盖范围,UE200则会监测到目标参考信号质量大于目标参考信号质量的门限值,UE200则不利用LR接收唤醒信号,维持MR开启,且重新开启定时器。
UE200在t2时刻进入到唤醒信号的覆盖范围之后,维持在该覆盖范围T时长,即迟滞时长,UE200则通过下述步骤S509在定时器的计时时长达到迟滞时长,即在t3时刻关闭MR,且控制LR接收唤醒信号。
S509、UE200关闭MR,并控制LR监听唤醒信号。
UE200判断定时器的计时时长达到迟滞时长,说明在UE200进入唤醒信号的覆盖范围的持续时长已经足够,可以关闭MR,并控制LR接收唤醒信号。
在一些实施例中,LR不受限于UE200出入唤醒信号的覆盖范围,持续处于开启状态。因UE200进入唤醒信号的覆盖范围,LR则自动会对唤醒信号进行监听,基于此,UE200控制LR接收唤醒信号可以理解成LR自动开始接收唤醒信号,无需UE200下发控制命令。
在另一些实施例中,UE离开唤醒信号的覆盖范围,UE200开启MR,且关闭LR。在该场景中,UE200进入到唤醒信号的覆盖范围,则需要控制LR打开,以监听唤醒信号。
需要说明的是,前述内容中,t0、t1、t2和t3属于时间轴的几个时刻点,并不限制两者之间只能为紧密的时刻点,不能包括时间间隔。
本申请实施例中,在UE进入到唤醒信号的覆盖范围内,UE不会立即关闭MR,而是延迟迟滞时长才关闭MR,不利用LR监听唤醒信号,且在迟滞时长内,若UE反复出入唤醒信号的覆盖范围,MR均维持MR处于开启状态,由MR接收寻呼消息或广播消息等,可以避免MR被频繁打开关闭导致的UE的其他硬件寿命缩减的问题,还可以避免MR被频繁打开关闭产生不必要的功耗。
参见图7所示的另一种低功耗唤醒信号的监听方法的流程图,该方法中,基站100向UE200配置目标参考信号质量的门限值和迟滞时长,目标参考信号质量的门限值和迟滞时长为唤醒信号的控制参数,用于在UE200通过目标参考信号的门限值确定自身离开唤醒信号的覆盖范围之后,开启MR且在迟滞时长内UE通过目标参考信号的门限值确定又进入唤醒信号的覆盖范围,不利用LR监听唤醒信号,且不关闭MR直至开启MR的时长达到迟滞时长。如图7所示,该方法包括:
S701、基站100向UE200配置目标参考信号质量的门限值和迟滞时长。
步骤S701的实现方式,可参见步骤S501,此处不再赘述。
基站100向UE200配置目标参数信号质量的门限值和迟滞时长之后,UE100可基于目标参数信号质量的门限值和迟滞时长,利用LR监听唤醒信号和控制MR关闭,或停止利用LR监听唤醒信号和开启MR。下述步骤S702至步骤S713提供了一种实现方式。
S702、UE200获取目标参考信号质量的门限值和迟滞时长。
S703、UE200判断目标参考信号质量是否不大于目标参考信号质量的门限值。
UE200可间断性监测基站100的目标参考信号质量,并获取目标参考信号质量的门限值和迟滞时长,UE200将监测得到的目标参考信号质量和目标参考信号质量的门限值进行比对,以判断目标参考信号质量是否不大于目标参考信号质量的门限值。
其中,UE200判断目标参考信号质量小于或等于目标参考信号质量的门限值,说明UE200离开唤醒信号的覆盖范围,则执行步骤S705,反之则执行步骤S704。
一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,UE200判断目标参考信号质量不大于目标参考信号质量的门限值则可指代是否不大于退出门限值。
S704、UE200维持MR关闭状态,由LR监听唤醒信号。
UE200监测得到的目标参考信号质量不小于目标参考信号质量的门限值,则说明UE200持续位于唤醒信号的覆盖范围内,MR则被维持关闭状态,由LR监听唤醒信号。
S705、UE200开启MR,启动定时器。
UE200监测得到的目标参考信号质量首次小于或等于目标参考信号质量的门限值,则说明UE200从唤醒信号的覆盖范围离开,则开启MR以接收寻呼消息或广播消息等,并启动定时器,UE还停止利用LR监听唤醒信号。
S706、UE200判断定时器的计时时长是否达到迟滞时长。
UE200启动定时器之后,判断定时器的计时时长是否达到迟滞时长,在判断出达到迟滞时长之后,则执行步骤S707。在判断出未达到迟滞时长,则执行步骤S709。
S707、UE200判断目标参考信号质量是否不小于目标参考信号质量的门限值。
其中,UE200离开唤醒信号的覆盖范围,且满足迟滞时长,UE200又通过步骤S707判断目标参考信号质量大于或等于目标参考信号质量的门限值,以确定UE200进入唤醒信号的覆盖范围,则执行步骤S708,反之说明UE200一直处于覆盖范围外,则持续维持MR处于开启状态。
一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,步骤S707可以理解成UE200判断目标参考信号质量是否大于或等于进入门限值。其中,大于或等于进入门限值则执行S708,反之则持续维持MR开启。
S708、UE200关闭MR,并控制LR监听唤醒信号。
结合图8所示,UE200处于唤醒信号的覆盖范围内,且在t0时刻离开覆盖范围,UE监测的目标参考信号质量小于目标参考信号质量的门限值,则停止利用LR监听唤醒信号,开启MR且启动定时器,该定时器的定时时长则为迟滞时长。之后,UE200一直在唤醒信号的覆盖范围外,等待迟滞时长T超时后,即到了t6时刻,UE200进入唤醒信号的覆盖范围,则关闭MR,控制LR监听唤醒信号。
其中,图8展示的定时器未运行可以理解成UE200一直处于唤醒信号的覆盖范围外,没有进出该覆盖范围导致UE200开启定时器。在该情况下,UE200首次通过判断目标参考信号质量大于目标参考信号质量的门限值,以确定UE200进入唤醒信号的覆盖范围,UE200关闭MR,控制LR监听唤醒信号。其中,控制LR监听唤醒信号可如对应图5的实施例内容的解释,此处不再赘述。
S709、UE200判断目标参考信号质量是否不小于目标参考信号质量的门限值。
UE200离开唤醒信号的覆盖范围,启动MR和定时器之后,通过步骤S706确定处于迟滞时长内,进一步通过步骤S709继续检测UE200是否又进入到唤醒信号的覆盖范围。
其中,UE200判断目标参考信号质量不小于目标参考信号质量的门限值,则执行步骤S710,当然UE判断目标参考信号小于目标参考信号质量的门限值,则说明UE200持续位于唤醒信号的覆盖范围外,则持续维持MR开启,维持停止LR监听唤醒信号。
在一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,步骤S709可以理解成UE200判断目标参考信号质量是否不小于进入门限值。其中,大于或等于进入门限值则执行S710,反之则持续维持MR开启,维持停止LR监听唤醒信号。
S710、UE200判断定时器的计时时长是否达到迟滞时长。
UE200结合步骤S706和步骤S709,判断出UE200在开启定时器之后的迟滞时长内又进入唤醒信号的覆盖范围。再通过步骤S710来判断是否达到迟滞时长,若达到迟滞时长,则执行步骤S711
S711、UE200关闭MR,并控制LR监听唤醒信号。
结合图8所示,UE200处于唤醒信号的覆盖范围内,且在t0时刻离开覆盖范围,UE监测的目标参考信号质量小于目标参考信号质量的门限值,则开启MR,停止利用LR监听唤醒信号且启动定时器,该定时器的定时时长则为迟滞时长。在迟滞时长内,UE200在t1时刻进入覆盖范围,UE200则不关闭MR,不利用LR监听唤醒信号。之后,UE200一直在唤醒信号的覆盖范围内,等待迟滞时长T超时后,即到了t2时刻控制LR监听唤醒信号,关闭MR。
S712、UE200判断目标参考信号质量是否不大于目标参考信号质量的门限值。
其中,UE200判断目标参考信号质量小于或等于目标参考信号质量的门限值,则执行步骤S713。
在一些实施例中,目标参考信号质量的门限值包括进入门限值和退出门限值,步骤S712可以理解成UE200判断目标参考信号质量是否小于退出门限值。其中,小于退出门限值则执行S713。
S713、UE200重新启动定时器。
结合图8所示,UE200处于唤醒信号的覆盖范围内,且在t3时刻离开覆盖范围,UE监测的目标参考信号质量小于目标参考信号质量的门限值,则开启MR,停止利用LR监听唤醒信号且启动定时器,该定时器的定时时长则为迟滞时长。在迟滞时长内,UE200在t4时刻进入覆盖范围,UE200则不关闭MR,不利用LR监听唤醒信号。之后,UE200在迟滞时长T内,在t5时刻,UE200再次离开唤醒信号的覆盖范围,即判断监测到的目标参考信号质量小或等于目标参考信号质量的门限值,则重新启动定时器。
步骤S5713之后,UE200则返回到步骤S706。
前述内容中,t0、t1、t2和t6属于时间轴的几个时刻点,并不限制两者之间只能为紧密的时刻点,不能包括时间间隔。同理,t3、t4和t5属于时间轴的几个时刻点,并不限制两者之间只能为紧密的时刻点,不能包括时间间隔。
本申请实施例中,在UE离开唤醒信号的覆盖范围后,启动MR,停止利用LR监听唤醒信号且还会启动定时器,在定时器的计时时长超过迟滞时长之后,UE再进入唤醒信号的覆盖范围,UE才会关闭MR,且利用LR监听唤醒信号。而在迟滞时长内,UE进入唤醒信号的覆盖范围,UE不会立即关闭MR,也不利用LR监听唤醒信号,而是等到定时器的计时时长超过迟滞时长之后,才会关机MR且利用LR监听唤醒信号。如此,在迟滞时长内,UE进出唤醒信号的覆盖范围,MR均处于开启状态以接收寻呼消息或广播消息,可以避免MR被频繁打开关闭导致的UE的其他硬件寿命缩减的问题,还可以避免MR被频繁打开关闭产生不必要的功耗。
图9展示了UE不配置迟滞时长和配置迟滞时长,其功耗的对比示意图。
假设30s内,UE进出唤醒信号的覆盖范围三次,即UE10s进出唤醒信号的覆盖范围一次。
如图9中(a)所示,MR的一次监听和服务小区的测量功耗为300,LR接收唤醒信号一次的功耗为5,UE在唤醒信号的覆盖范围边缘进出一次,MR被开启的功耗为15000~40000,且MR被开启,还需要进行一次同步,该同步的功耗为1000~3000。
图9中(b)所示,MR进出一次唤醒信号的覆盖范围之后,MR在迟滞时长内持续处于开启状态,待30s后,UE的功耗仅为图9中(a)展示的16%。
具体计算如下:
(30/0.6)*300=15000(15000/30000)/3=16%
上述两个实施例提供了两种基于目标参考信号质量的门限值和迟滞时长来控制监听唤醒信号的方案,能够避免MR被频繁打开关闭导致的UE的其他硬件寿命缩减的问题,还可以避免MR被频繁打开关闭产生不必要的功耗。
本申请实施例还提供了另一种技术方案来避免上述两个问题,该技术方案中,基站100向UE200配置目标参考信号质量的门限值和偏移值(offset)。在一些实施例中,基站100配置的目标参考信号质量的门限值包括:进入门限值和退出门限值,进入门限值和退出门限值等价,该偏移值为目标参考信号质量的进入门限值的偏移值,可以理解成:UE200监测得到的目标参考信号质量大于或等于进入门限值和偏移值的和,UE才可关闭MR,利用LR监听唤醒信号。在另一些实施例中,基站100配置的目标参考信号质量的门限值包括进入门限值,UE200可基于该门限值得到其等价的退出门限值,同理,该偏移值为目标参考信号质量的进入门限值的偏移值。其中,进入门限值和退出门限值等价的解释,可参见前述内容。
参见图10所示的另一种低功耗唤醒信号的监听方法的流程图,该方法,包括:
S1001、基站100向UE200配置目标参考信号质量的门限值和偏移值。
步骤S1001中提出的基站100向UE200配置数据的实现方式,可参见步骤S501,此处不再赘述。并且,目标参考信号质量的门限值和偏移值,可参见上述内容的解释,此处不再赘述,
基站100向UE200配置目标参数信号质量的门限值和偏移值之后,UE100可基于目标参数信号质量的门限值和偏移值,利用LR监听低功耗唤醒信号和关闭MR,或者停止利用LR监听低功耗唤醒信号和开启MR。下述步骤S1002至步骤S1006提供了一种实现方式。
S1002、UE200获取目标参考信号质量的门限值和偏移值。
S1003、UE200在LR接收唤醒信号的过程中,判断目标参考信号质量是否小于目标参考信号质量的门限值。
其中,UE200的LR监听唤醒信号,可以理解成UE200处于唤醒信号的覆盖范围。UE200以监测的目标参考信号质量,来和目标参考信号质量的门限值进行比对,来确定UE200是否离开唤醒信号的覆盖范围。其中,与UE200监测的目标参考信号质量进行比对的目标参考信号质量的门限值,可以理解成是退出门限值。
在UE200判断目标参考信号质量小于目标参考信号质量的门限值时,UE200执行步骤S1004;反之则维持MR处于关闭状态,且由LR监听唤醒信号,另外,还要间断性的执行步骤S1003。
S1004、UE200开启MR,停止利用LR监听唤醒信号。
UE200判断目标参考信号质量小于目标参考信号质量的门限值,则说明UE200离开唤醒信号的覆盖范围,UE200开启MR,由MR接收寻呼消息或者广播消息等。当然,LR可被UE关闭或维持其处于开启状态,因UE未处于唤醒信号的覆盖范围,因此,即便LR处于开启状态,其也无法监听到唤醒信号,不会对MR的运行过程造成干扰。
结合图11所示,UE处于唤醒信号的覆盖范围内,UE将监测得到的目标参考信号质量与退出门限值进行比对,图11中示例性的展示了退出门限值为LP-RSRP_exit。UE判断目标参考信号质量小于退出门限值,则开启MR。
S1005、UE200在MR的开启状态下,判断目标参考信号质量是否大于或等于门限值+偏移值。
MR被开启处于运行状态时,UE200还可以基于监测的目标参考信号质量,来判断UE200是否又进入到唤醒信号的覆盖范围。UE200判断监测的目标参考信号质量是否大于或等于门限值+偏移值,该门限值则为进入门限值。
其中,UE200判断目标参考信号质量大于或等于门限值+偏移值,则执行步骤S1006。
S1006、UE200关闭MR,并控制LR监听唤醒信号。
其中,UE200控制LR接收唤醒信号的解释可如前述内容,此处不再赘述。
结合图11所示,UE处于唤醒信号的覆盖范围外,开始进入唤醒信号的覆盖范围,UE监测得到的目标参考信号质量会随之增大,其大于进入门限值,图11示例性的展示进入门限值为RSRP_entry,UE还维持MR开启,由MR接收寻呼消息或广播消息,直至UE监测得到的目标参考信号质量大于或等于进入门限值和偏移值,UE才可关闭MR,由LR监听唤醒信号。如此,可避免UE在唤醒信号的覆盖范围边缘且反复进出,导致MR被频繁打开关闭进而导致UE的其他硬件寿命缩减的问题,还可以避免MR被频繁打开关闭产生不必要的功耗。
