If the UE detects a GTS on the PoSS occasion, and the detected GTS indicates that the UE has no data scheduling within the corresponding OnDuration time period, the UE enters the dormant state again. If the UE does not detect the GTS on the PoSS occasion or the detected GTS indicates that the UE has data scheduling in the corresponding OnDuration time period, the UE will be awakened and monitor the PDCCH.

Description
本申请要求于2019年12月14日提交国家知识产权局、申请号为201911287187.7、申请名称为“资源配置方法、网络设备及计算机存储介质”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。
本申请属于通信技术领域,尤其涉及一种资源配置方法、网络设备及计算机存储介质。
当终端设备处于非连续接收(Discontinuous Reception,DRX)模式下时,基站侧的网络设备需要指示终端设备进行信道状态信息(Channel State Information,CSI)的测量与上报。
终端设备的CSI测量资源和上报资源由基站侧的网络设备进行配置。目前,当基站侧的网络设备为终端设备配置CSI测量资源和上报资源时,往往采用相同的资源配置方案。
但是,在不同的DRX周期,终端设备的状态差异较大,采用单一的资源配置方案难以适应无线通信***中差异化的终端状态,容易造成资源配置过多或过少。
发明内容
有鉴于此,本申请实施例提供了一种资源配置方法、网络设备及计算机存储介质,以解决现有技术中采用单一的资源配置方案难以适用无线通信***中差异化的终端状态,容易造成资源配置过多或过少的问题。
本申请实施例的第一方面提供了一种资源配置方法,包括:
网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息;
所述网络设备将所述资源配置信息发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量与上报。
需要说明的是,待配置的DRX周期可以根据用户的配置方案进行设置。待配置的DRX周期可以为有数据传输的DRX周期,也可以为每一个DRX周期。
第一参数的类型可以根据实际情况进行选择。预设的资源配置信息表为用户预先设置的资源配置表。预设的资源配置表中记录着第一参数与资源配置信息的对应关系。用户可以通过实验测试、理论计算等方式确定各第一参数对应的资源配置信息,从而得到第一参数与资源配置信息的对应关系,建立预设的资源配置表。
在第一方面的一种可能的实现方式中,所述第一参数为所述待配置的DRX周期的周期长度;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源 配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取待配置的DRX周期的周期长度,在预设的资源配置表中查询与所述周期长度对应的资源配置信息。
需要说明的是,待配置的DRX周期的周期长度越长,则待配置的DRX周期内网络设备和用户终端设备发生数据交互的可能性越大,则网络设备应当配置更多的CSI测量资源和上报资源;待配置的DRX周期的周期越短,则待配置的DRX周期内网络设备与用户终端设备发生数据交互的可能性越小,则网络设备应当配置更少的CSI测量资源和上报资源。
因此,可以将待配置的DRX周期的周期长度作为第一参数,根据待配置的DRX周期的周期长度进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为所述待配置的DRX周期的周期类型;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取待配置的DRX周期的周期类型,在预设的资源配置表中查询与所述周期类型对应的资源配置信息。
需要说明的是,待配置的DRX周期的周期类型可以包括短DRX周期和长DRX周期。当待配置的DRX周期的周期类型为短DRX周期时,在待配置的DRX周期内网络设备和用户终端设备发生数据交互的可能性较小,网络设备应当配置较少的CSI测量资源和上报资源;当待配置的DRX周期的周期类型为长DRX周期时,在待配置的DRX周期内网络设备和用户终端设备发生数据交互的可能性较大,网络设备应当配置较多的CSI测量资源和上报资源。
因此,可以将待配置的DRX周期的周期类型作为第一参数,根据待配置的DRX周期的周期类型进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备在所述待配置的DRX周期之前的总休眠时间;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取终端设备在待配置的DRX周期之前的总休眠时间,确定所述总休眠时间所处的休眠时间区间;
所述网络设备在预设的资源配置表中查询与所述休眠时间区间对应的资源配置信息。
需要说明的是,如果终端设备在待配置的DRX周期之前的总休眠时间越长,则网络设备应当配置更多的CSI测量资源和上报资源;如果终端设备在待配置的DRX周期之前的总休眠时间越短,则网络设备应当配置更少的CSI测量资源和上报资源。
因此,可以将终端设备在待配置的DRX周期之前的总休眠时间作为第一参数,根据终端设备在待配置的DRX周期之前的总休眠时间进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备在所述待配置的DRX周期之前的总休眠次数;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取终端设备在待配置的DRX周期之前的总休眠次数,在预设的资源配置表中查询与所述总休眠次数对应的资源配置信息。
需要说明的是,如果终端设备在待配置的DRX周期之前的总休眠次数越多,则网络设备应当配置更多的CSI测量资源和上报资源;如果终端设备在待配置的DRX周期之前的总休眠次数越少,则网络设备应当配置更少的CSI测量资源和上报资源。
因此,可以将终端设备在待配置的DRX周期之前的总休眠次数作为第一参数,根据终端设备在待配置的DRX周期之前的总休眠次数进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为所述待配置的DRX周期对应的功率节省信号的信号类型;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取待配置的DRX周期对应的功率节省信号的信号类型,在预设的资源配置表中查询与所述信号类型对应的资源配置信息。
需要说明的是,功率节省信号的信号类型可以包括唤醒信号(Wake Up Signal,WUS)信号和休眠信号(Go to Sleep Signal,GTS)。
当功率节省信号的信号类型为WUS信号时,表示终端设备在待配置的DRX周期内需要与网络设备进行数据交互,此时网络设备应当配置较多的CSI测量资源和上报资源;当功率节省信号的信号类型为GTS信号时,表示终端设备在待配置的DRX周期内处于休眠状态,不需要与网络设备进行数据交互,此时网络设备应当配置较少的CSI测量资源和上报资源。
因此,可以将待配置的DRX周期对应的功率节省信号的信号类型作为第一参数,根据待配置的DRX周期对应的功率节省信号的信号类型进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备当前的业务量;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备测量终端设备当前的业务量,确定所述业务量所处的业务量区间;
所述网络设备在预设的资源配置表中查询与所述业务量区间对应的资源配置信息。
需要说明的是,网络设备可以在业务量测量周期内统计用户终端设备的业务量,将其作为终端设备当前的业务量。终端设备当前的业务量越多,则表示在待配置的DRX周期内,网络设备需要与终端设备交互的数据越多,网络设备应当配置更多的CSI测量资源和上报资源;终端设备当前的业务量越少,则表示在待配置的DRX周期内,网络设备需要与终端设备交互的数据越少,网络设备应当配置更少的CSI测量资源和上报资源。
因此,可以将终端设备当前的业务量作为第一参数,根据终端设备当前的业务量进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备当前的业务对应的服务质量等级标识的优先级;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取终端设备当前的业务对应的服务质量等级标识的优先级,在预设的资源配置表中查询与所述服务质量等级标识的优先级对应的资源配置信息。
需要说明的是,对于QCI(QoS Class Identifier,服务质量等级标识)优先级较高的业务,例如GBR(Guaranteed Bit Rate,保证比特速率)类的业务,应当配置较多的CSI测量资源和上报资源以保证业务的服务质量;而对于QCI优先级较低的业务,例如Non-GBR类业务,相对而言网络设备可以配置较少的CSI测量资源和上报资源。
因此,可以将终端设备当前的业务对应的服务质量等级标识的优先级作为第一参数,根据终端设备当前的业务对应的服务质量等级标识的优先级进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备与网络设备的距离;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取终端设备与网络设备的距离,确定所述距离所处的距离区间;
所述网络设备在预设的资源配置表中查询与所述距离区间对应的资源配置信息。
需要说明的是,如果当前终端设备距离网络设备较远,则表示终端设备可能处于小区边缘。此时,如果终端设备没有满足退出DRX模式的触发条件,即终端设备没有满足小区切换或终端设备在无线资源控制连接(Radio Resource Control Connected,RRC_Connected)状态下因为信道环境较差的触发退出DRX模式的条件,则终端设备的信道质量波动和时延很大。此时,如果网络设备配置的CSI测量资源和上报资源少,则终端设备可能无法及时上报信道质量指示(Channel Quality Indication,CQI)进行调制与编码策略(Modulation and Coding Scheme,MCS)调整,网络设备的吞吐率性能会受一定程度影响。
因此,可以将终端设备与网络设备的距离作为第一参数,根据终端设备与网络设备的距离进行资源配置。
在第一方面的另一种可能的实现方式中,所述第一参数为终端设备的移动速度;
相应的,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
所述网络设备获取终端设备的移动速度,确定所述移动速度所处的速度区间;
所述网络设备在预设的资源配置表中查询与所述速度区间对应的资源配置信息。
需要说明的是,如果终端设备的移动速度较高,且终端设备没有处罚退出DRX模式的条件,则可能出现终端设备还没完成CSI测量,终端设备就已经离开原网络设备的覆盖范围的情况,从而导致终端设备网络切换失败和出现掉话情况。因此,可以将终端设备的移动速度进行CSI测量资源和上报资源的配置。如果终端设备的移动速度较快,则网络设备应当配置较多的CSI测量资源和上报资源,以指示终端设备尽快完成CSI测量和上报,减少网络切换失败和掉话情况;如果终端设备的移动速度较慢,则相对而言网络设备可以配置较少的CSI测量资源和上报资源。
因此,可以将终端设备的移动速度作为第一参数,根据终端设备的移动速度进行 资源配置。
在第一方面的一种可能的实现方式中,所述网络设备将所述资源配置信息发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量与上报包括:
所述网络设备将所述资源配置信息封装至物理下行信道的下行信号中;
所述网络设备通过所述物理下行信道将所述下行信号发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量与上报。
在第一方面的一种可能的实现方式中,所述下行信号为下行控制信息、媒体接入控制控制单元、无线资源控制信令或参考信号指示信息。
在第一方面的一种可能的实现方式中,所述网络设备将所述资源配置信息发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量与上报包括:
所述网络设备将所述资源配置信息发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量,并将测量得到的信道状态信息通过物理上行控制信道或物理上行共享信道上报至所述网络设备。
在第一方面的一种可能的实现方式中,所述信道状态信息包括信道质量指示信号、预编码矩阵指示符、秩指示符、层指示符中的一种或多种的组合。
在第一方面的一种可能的实现方式中,所述资源配置信息包括信道状态信息测量参考信号的时频位置、信道状态信息测量参考信号的数目、信道状态信息测量参考信号的周期、信道状态信息上报资源的时频位置、信道状态信息上报资源的数目、信道状态信息上报资源的周期中的一种或多种的组合。
在第一方面的一种可能的实现方式中,所述网络设备获取待配置的DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息包括:
网络设备在每一个DRX周期开始之前,获取所述DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息。
需要说明的是,将每一个DRX周期都视为待配置的DRX周期,则络设备即使在终端设备经历了较长时间的休眠期也能及时获取CSI信息,使得网络设备基于波束传递高频信息时,鲁棒性更强,降低数据调度时延。
本申请实施例的第二方面提供了一种网络设备,包括:

为了说明本申请所述的技术方案,下面通过具体实施例来进行说明。
应当理解,当在本说明书和所附权利要求书中使用时,术语“包括”指示所描述特征、整体、步骤、操作、元素和/或组件的存在,但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
还应当理解,在此本申请说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本申请。如在本申请说明书和所附权利要求书中所使用的那样,除非上下文清楚地指明其它情况,否则单数形式的“一”、“一个”及“该”意在包括复数形式。
还应当进一步理解,在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合,并且包括这些组合。
如在本说明书和所附权利要求书中所使用的那样,术语“如果”可以依据上下文被解释为“当...时”或“一旦”或“响应于确定”或“响应于检测到”。类似地,短语“如果确定”或“如果检测到[所描述条件或事件]”可以依据上下文被解释为意指“一旦确定”或“响应于确定”或“一旦检测到[所描述条件或事件]”或“响应于检测到[所描述条件或事件]”。
另外,在本申请的描述中,术语“第一”、“第二”、“第三”等仅用于区分描述,而不能理解为指示或暗示相对重要性。
本申请实施例可以应用于无线通信***。无线通信***通常由小区(cell)组成,每个小区包含一个基站(Base Station,BS),基站向多个终端设备提供通信服务。其中基站包含基带单元(Baseband Unit,BBU)和远端射频单元(Remote Radio Unit,RRU)。BBU和RRU可以放置在不同的地方,例如:RRU拉远,放置于离高话务量的开阔区域,BBU放置于中心机房。BBU和RRU也可以放置在同一机房。BBU和RRU也可以为一个机架下的不同部件。
在本申请实施例中,所述基站是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述基站可以包括各种形式的宏基站,微基站(也称为小站),中继站,接入点,传输接收点(Transmission Reception Point,TRP)等。在采用不同的无线接入技术的***中,具备基站功能的设备的名称可能会有所不同,例如,在长期 演进(Long Term Evolution,LTE)***中,称为演进的节点B(evolved NodeB,eNB或者eNodeB),在第三代(3rd Generation,3G)***中,称为节点B(Node B,NB)等。为方便描述,本申请所有实施例中,上述为终端设备提供无线通信功能的装置统称为网络设备。
本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端设备也可以称为移动台(Mobile Station,MS)、终端(Terminal),还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能手机(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication,MTC)终端等。为方便描述,本申请所有实施例中,上面提到的设备统称为终端设备。
在当前的长期演进(Long Term Evolution,LTE)***与第五代无线接入***(5th Generation,5G)新空口(New Radio,NR)中,用户终端设备(User Equipment,UE)所做的物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测贡献了相当大的UE耗电占比。
PDCCH用于为下行链路发送信息,其传输的信息包括公共控制信息(例如***信息、寻呼信息等)和用户专属信息(下行资源分配指示、上行功率控制参数等)。
在实际的应用过程中,由于包的数据流通常是突发性的。在一段时间内,网络设备与UE之间有数据传输,但是在接下来的一段较长时间内可能是没有数据传输的。因此,UE所做的大部分PDCCH监听是没有检测到任何指示的,且这些没有任何指示的PDCCH监听会产生相当大的UE耗电。
基于上述情况,在LTE与5G NR中都引入非连续接收DRX(Discontinuous Reception,DRX)技术。在DRX技术中,可以在没有数据传输时,通过使UE停止检测PDCCH并停止接收相应数据传输来降低UE的功耗,从而提升UE的电池使用时间。
在DRX技术中,基站侧的网络设备可以为处于无线资源控制状态的UE配置DRX周期(DRX cycle)。如图2所示,DRX cycle中包含一个监听持续时间(On Duration)的时间区域和非连续接收时间(Opportunity for DRX)的时间区域。
在On Duration的时间内,UE可以检测PDCCH和/或接收物理下行共享信道(Physical Downklink Shared Channel,PDSCH)。UE在每一个DRX cycle时间起始位置(即OnDuration的时间起始位置)开启一个定时器,该定时器的时间长度即为OnDuration的时间长度,该定时器可以称之为持续时间定时器(DRX-onDurationTimer),DRX-onDurationTimer的范围可以根据实际情况进行设置,例如,可以将DRX-onDurationTimer的范围设置为1~1200ms。
如图3所示,UE在DRX-onDurationTimer的时间范围内检测PDCCH。如果UE在DRX-onDurationTimer的时间范围内没有检测到PDCCH,那么DRX-onDurationTimer到期后UE进入睡眠状态,从而降低UE的功耗。如果UE在DRX-onDurationTimer的时间范围内检测到了PDCCH,那么UE就会开启DRX机制中的非激活定时器(DRX-InactivityTimer)。如果在DRX-InactivityTimer的运行时间 内,UE继续检测到了PDCCH,那么UE会重置该非激活定时器重新开始计数。如果非激活定时器正在运行,则即使DRX-onDurationTimer超时,UE依然需要继续检测PDCCH,直到DRX-InactivityTimer超时。
在DRX机制中,还有其它一些定时器,比如DRX下行重传定时器(drx-RetransmissionTimerDL)、DRX上行重传定时器(drx-RetransmissionTimerUL)。但是这些定时器的作用与本申请实施例的方案无关,在此不作详细描述。如果上述定时器(包括DRX-onDurationTimer、DRX-InactivityTimer以及其他定时器)中的任意一个正在运行,那么UE就会处于激活时间(Active Time)。在DRX机制中,如果UE处于Active Time,那么UE就需要检测PDCCH。注意的是,还有其它一些情况会让UE处于Active Time,但与本申请实施例的方案无关,在此不作详细描述。
DRX cycle、onDuration和Opportunity for DRX都是由基站侧的网络设备配置给UE。如图4所示,DRX周期分为短DRX周期(short DRX cycle)以及长DRX周期(long DRX cycle)。short DRX cycle和long DRX cycle的周期长度不同,UE按照特定的规则在两种不同周期长度的DRX cycle之间进行切换。
通常而言,当DRX-InactivityTimer超时或收到DRX媒体接入控制控制单元(Media Access Control-Control Element,MAC-CE)时,如果UE没有被配置short DRX cycle,则直接使用long C-DRX cycle;如果UE配置了short DRX cycle,则UE使用short DRX cycle并启动或重启短DRX周期定时器(drxShortCycleTimer),当drxShortCycleTimer超时,则UE使用long DRX cycle。
当UE使用short DRX cycle或long DRX cycle时,如果子帧编号满足以下条件,则启动DRX-onDurationTimer:
(SFN*N+sn)mod(short DRX cycle)=(drxStartOffset)mod(short DRX cycle)
(SFN*N+sn)mod(short DRX cycle)=drxStartOffset
其中,SFN(System Frame Number)为***帧号,N为正整数,N为一个SFN周期内的子帧数量,sn(subframe number)为子帧编号,mod为取模函数,drxStartOffset为周期开始子帧号。
在DRX技术的实际应用过程中,由于数据传输在时间上具有突发性和稀疏性,因此,即使UE只在DRX的active time做PDCCH检测,也有相当大的比例检测不到任何指示,功耗浪费严重。特别是在NR***中,UE会工作在更大的射频和基带带宽,导致UE浪费的功耗更高。
基于上述情况,在NR Rel-16技术标准中会引入功率节省信号(Power Saving Signal,PoSS)以进一步降低UE功耗。在DRX cycle的OnDuration之前,基站侧的网络设备向UE发送PoSS,以指示UE在接下来的一个或多个DRX cycle内是否需要唤醒执行监听PDCCH、接收PDSCH、进行测量上报等操作中的一种或多种。
PoSS可以为唤醒信号(Wake Up Signal,WUS),即UE需要醒来。当PoSS为WUS时,UE的行为就像之前C-DRX规定的一样。或者,PoSS也可以为休眠信号(Go to Sleep,GTS),即UE在接下来的C-DRX cycle进行休眠,不需要进行PDCCH监听。
对于支持WUS的UE,基站侧的网络设备可以在DRX cycle的OnDuration起始位置之前的PoSS occasion(功率节省信号时间)以不连续发送(Discontinuous Transmission, DTX)形式发送WUS,即基站侧的网络设备根据调度数据的需求决定是否在PoSSoccasion上发送WUS。UE需要在PoSS occasion判断基站是否发送WUS。如图5所示,如果UE在PoSS occasion上没有检测到WUS或检测到的WUS指示UE在对应的OnDuration时间段内没有数据调度,则UE可以直接进入休眠状态而无需进行PDCCH监听。如图6所示,如果UE在PoSS occasion上检测到WUS,且检测到的WUS指示UE在对应OnDuration时间段内有数据调度,则UE就会被唤醒,UE可以按照之前DRX规定的流程启动DRX-onDurationTimer,检测PDCCH。
图6中的空白矩形表示OnDuration时间段,斜线标记的矩形表示DRX-InactivityTimer,UE在PoSS occasion上检测到WUS,且检测到的WUS指示UE在对应OnDuration时间段内有数据调度,则UE逐渐被唤醒,并在OnDuration时间段开始检测PDCCH。UE检测到PDCCH,则启动DRX-InactivityTimer。DRX-InactivityTimer结束后,DRX-onDurationTimer尚未结束,表示OnDuration时间段尚未结束,继续对PDCCH进行监测。DRX-onDurationTimer结束后,UE逐渐进入休眠状态。
与WUS相似的是,对于支持GTS的UE,基站侧的网络设备可以在DRX cycle的OnDuration起始位置之前的PoSS occasion以DTX形式发送GTS。UE需要在PoSS occasion判断基站是否发送GTS。如果UE在PoSS occasion上检测到GTS,且检测到的GTS指示UE在对应OnDuration时间段内没有数据调度时,那么UE就重新进入休眠状态。如果UE在PoSS occasion上没有检测到GTS或检测到的GTS指示UE在对应OnDuration时间段内有数据调度时,那么UE就会被唤醒,对PDCCH进行监听。
在另一些可能的情况中,基站侧的网络设备可以通过GTS指示UE在一段时间内进入休眠状态或停止检测PDCCH一段时间,该时间可以被称为休眠时间(Sleep Duration)。如图7所示,UE在OnDuration时间段内检测到PDCCH,则启动DRX-InactivityTimer。UE在DRX-InactivityTimer的持续时间内检测到GTS,包含了休眠时间T的GTS表示基站侧的网络设备确定UE在接收到GTS信号后的连续时间T内,不需要给UE调度任何数据以及发送PDCCH。所以,在检测到包含了休眠时间T的GTS并解析后,UE进入休眠状态不进行PDCCH检测,关闭部分射频或基带电路,并在休眠时间T后唤醒检测PoSS信号或PDCCH。通过这种方式,可以减少UE不必要的功耗。
PoSS可以是序列信号,也可以是数据信号。当PoSS为数据信号时,PoSS可以是下行控制信息(Downlink Control Information,DCI)、物理下行共享信道(Physical Downlink Shared Channel,PDSCH)、媒体介入控制控制单元(Media Access Control-Control Element,MAC-CE)、无线资源控制(Radio Resource Control,RRC)信令等数字信号中的一种。
在目前的C-DRX中,UE只能在DRX中的Active time进行CSI测量与CSI上报。基站侧的网络设备无法在DRX cycle的起始时及时有效的获得CSI信息对数据传输链路进行调整,从而降低了***的频带效率并且有可能由于数据重传带来UE功耗的增加。
在PoSS occasion和OnDuration之间通常设置有补偿时间(offset duration),offset duration用于UE执行PoSS检测及解析其指示的含义、时频同步、信道状态信息(Channel State Information,CSI)测量、波束管理等处理。UE需要执行的处理越多,所需的时间越长。
为了提高接收数据的可靠性,基站侧的网络设备可以在有数据调度时,考虑在offset duration放置参考信号用于CSI的测量与上报,基于PoSS信号触发CSI上报,从而提高OnDuration内与下一个DRX cycle的数据传输效率。上述参考信号可以为信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、解调参考信号(Demodulation Reference Signal,DM-RS)、时域频域跟踪参考信号(Time/Frequency Tracking Signal,TRS)、同步信号块(Synchronization Signal Block,SSB)信号等类型的参考信号。参考信号的数量可以为一个或一个以上。
此时,PoSS既可以作为功率节省信号指示UE在当前DRX周期唤醒收发数据,也可以作为CSI上报的触发信号。基站侧的网络设备不需要专用的PDCCH触发CSI上报,减少网络信令开销。并且,CSI上报是按需上报,只有当UE被PoSS唤醒进行数据收发时才被触发进行CSI上报,从而使得CSI的测量与上报更有效,使得基站侧的网络设备可以在DRX的active time获得及时的CSI信息进行数据传输。
但是,当基站侧的网络设备在配置CSI的测量资源和上报资源时,往往采用相同的资源配置方案,单一的资源配置方案难以适用NR等无线通信***中差异化的UE状态,容易造成资源配置过高或过低。
有鉴于此,本申请实施例提供了一种资源配置方法,网络设备获取与待配置的DRX周期相关的第一参数,第一参数用于表征待配置的DRX周期的状态,根据第一参数确定信道状态的测量资源和上报资源的配置方案,从而根据UE的状态进行合理地资源配置,在确保UE能够在保证功率节省增益的情况,实现更合理有效的资源配置方案,解决了现有技术中采用单一的资源配置方案难以适用无线通信***中差异化的UE状态,容易造成资源配置过多或过少的问题。
接下来,从基站侧的网络设备的角度,对本申请实施例提供的资源配置方法进行详细介绍。参见图1所示的资源配置方法的流程图,该方法包括:
S101、网络设备获取待配置的非连续接收DRX周期对应的第一参数,并在预设的资源配置表中查询与所述第一参数对应的资源配置信息;
待配置的DRX周期可以根据用户的配置方案进行设置。在一些可能的实现方式中,待配置的DRX周期可以为有数据传输的DRX周期。在这种配置方案中,网络设备可以在DRX周期获得到CSI信息以进行数据传输链路的配置,提高***的频带效率。
但是这种方案仅考虑了有数据调度的DRX周期,没有考虑处于休眠状态的DRX周期。NR***基于波束传输高频信息,此时,如果忽视休眠状态下的DRX周期的上报,终端设备可能会出现PoSS信号等高频信号接收失败的情况,从而导致调度时延增加。
例如,DRX周期1至DRX周期5为时间轴上依次排列的5个DRX周期。DRX周期1中网络设备和用户的终端设备存在数据交互,DRX周期2至DRX周期4为休眠状态的DRX周期,DRX周期5中网络设备和用户的终端设备存在数据交互。
此时,如果只将有数据调度的DRX周期视为待配置的DRX周期,则只有在DRX 周期1和DRX周期5终端设备需要进行CSI的测量与上报。但是,由于终端设备经历了3个DRX周期的休眠,在DRX周期5时,终端设备的***状态可能发生了较大的变化,例如天线阵列朝向发生改变等。当网络设备以波束的形式传递高频信息时,波束的指向性较强,覆盖角度较窄,如果终端设备的***状态发生了较大的变化,且网络设备没有对数据传输链路进行调整,则网络设备可能无法将PoSS信号或其他高频信号传递至终端设备,导致终端设备出现数据接收失败的情况,造成调度时延增加。
因此,在另一些可能的实现方式中,待配置的DRX周期可以为每一个DRX周期,即不论该DRX周期内网络设备是否需要跟终端设备进行数据交互,都将该周期视为待配置的DRX周期。此时,网络设备即使在终端设备经历了较长时间的休眠期也能及时获取CSI信息,使得网络设备基于波束传递高频信息时,鲁棒性更强,降低数据调度时延。
例如,参照上一示例,如果将每一个DRX周期都视为待配置的DRX周期,则即使是休眠状态,网络设备也会为终端设备配置DRX周期2至DRX周期4的CSI测量资源,并根据终端设备反馈的CSI(例如信道质量指示(Channel Quality Indication,CQI)等信息)调节数据传输链路,即使终端设备在DRX周期4中***状态发生变化,其变化幅度也比DRX周期2至DRX周期4内终端设备的***状态的变化幅度小,网络设备在DRX周期5可以相对准确将PoSS信号等高频信号传输至终端设备,提高高频信息的传输性能,降低数据调度时延。
在确定了待配置的DRX周期之后,网络设备可以获取待配置的DRX周期对应的第一参数。在一些可能的实现方式中,网络设备可以在待配置的DRX周期内进行CSI测量资源和上报资源的配置。但是这种方式中,网络设备无法在待配置的DRX周期的起始时及时有效的获得CSI信息对数据传输链路进行调整,从而降低了***的频带效率并且有可能由于数据重传带来终端设备功耗的增加。
在另一些可能的实现方式中,为了提高数据接收的可靠性,网络设备可以在待配置的DRX周期开始之前,即待配置的DRX周期的前一DRX周期的结尾处(例如前一DRX周期结尾处的offset duration),获取待配置的DRX周期对应的第一参数进行CSI测量资源和上报资源的配置,从而使网络设备可以在待配置的DRX周期开始之前及时获取到CSI信息对数据传输链路进行调整,提高***的频带效率,降低终端设备的功耗。
第一参数的具体类型可以根据实际情况进行设置。在一些可能的实现方式中,第一参数可以为待配置的DRX周期的周期长度。待配置的DRX周期的周期长度越长,则待配置的DRX周期内网络设备和用户终端设备发生数据交互的可能性越大,则网络设备应当配置更多的CSI测量资源和上报资源;待配置的DRX周期的周期越短,则待配置的DRX周期内网络设备与用户终端设备发生数据交互的可能性越小,则网络设备应当配置更少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以通过查询周期配置参数(例如gNBDrxParamGroup.LongDrxcycle、gNBDrxParamGroup.ShortDrxcycle等)获取待配置的DRX周期对应的周期长度,在预设的资源配置表中查询与上述周期长度对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为待配置的DRX周期的周期类型。终 端设备的周期类型可以包括短DRX周期和长DRX周期。当待配置的DRX周期的周期类型为短DRX周期时,短DRX周期的周期长度较短,网络设备在待配置的DRX周期内与用户终端设备发生数据交互的可能性较小,网络设备应当配置较少的CSI测量资源和上报资源;当待配置的DRX周期的周期类型为长DRX周期时,长DRX周期的周期长度较长,网络设备在待配置的DRX周期内与用户终端设备发生数据交互的可能性较大,网络设备应当配置较多的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取待配置的DRX周期对应的周期类型,在预设的资源配置表中查询与上述周期类型对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为终端设备在待配置的DRX周期之前的总休眠时间。如果终端设备在待配置的DRX周期之前的总休眠时间越长,则终端设备的***状态变化越大,网络设备应当配置更多的CSI测量资源和上报资源;如果终端设备在待配置的DRX周期之前的总休眠时间越短,则终端设备的***状态变化越小,网络设备应当配置更少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取终端设备在待配置的DRX周期之前的总休眠时间,根据上述总休眠时间所处的休眠时间区间,在预设的资源配置表中查询与上述休眠时间区间对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为终端设备在待配置的DRX周期之前的总休眠次数。如果终端设备在待配置的DRX周期之前的总休眠次数越多,则终端设备的***状态变化越大,网络设备应当配置更多的CSI测量资源和上报资源;如果终端设备在待配置的DRX周期之前的总休眠次数越少,则终端设备的***状态变化越小,网络设备应当配置更少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取终端设备在待配置的DRX周期之前的总休眠次数,在预设的资源配置表中查询与上述总休眠次数对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为网络设备即将下发终端设备的功率节省信号(PoSS)的信号类型。功率节省信号用于指示终端设备在待配置的DRX周期是唤醒状态还是休眠状态。功率节省信号的信号类型可以包括WUS信号和GTS信号。当功率节省信号的信号类型为WUS信号时,表示终端设备在待配置的DRX周期内需要与网络设备进行数据交互,此时网络设备可以配置较多的CSI测量资源和上报资源;当功率节省信号的信号类型为GTS信号时,表示终端设备在待配置的DRX周期内处于休眠状态,不需要与网络设备进行数据交互,此时网络设备可以配置较少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取待配置的DRX周期对应的功率节省信号的信号类型,在预设的资源配置表中查询与上述功率节省信号的信号类型对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为终端设备当前的业务量。网络设备可以在业务量测量周期(CellDrxPara.DataAmountStatTimer)内统计用户终端设备的业务量,将其作为终端设备当前的业务量。在终端设备的业务量没有高于退出DRX模式的业务量门限值(例如CellDrxPara.FddExitDrdThd、CellDrxPara.TddExitDrdThd)的情况下,终端设备当前的业务量越多,则表示在待配置的DRX周期内,网络设备需要与终端设备交互的数据越多,网络设备应当配置更多的CSI测量资源和上报资源;终 端设备当前的业务量越少,则表示在待配置的DRX周期内,网络设备需要与终端设备交互的数据越少,网络设备应当配置更少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取终端设备当前的业务量,确定上述业务量所处的业务量区间,在预设的资源配置表中查询与上述业务量区间对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为终端设备当前业务对应的服务质量等级标识(QoS Class Identifier,QCI)的优先级。总体而言,对于QCI优先级较高的业务,例如保证比特速率(Guaranteed Bit Rate,GBR)类的业务(QCI=5,6,7,8,9,69,70),应当配置较多的CSI测量资源和上报资源以保证业务的服务质量;而对于QCI优先级较低的业务,例如非保证比特速率(Non Guaranteed Bit Rate,Non-GBR)类业务(QCI=1,2,3,4,65,66),相对而言网络设备可以配置较少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取终端设备当前业务对应的服务质量等级标识的优先级,在预设的资源配置表中查询与上述优先级对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为当前终端设备与网络设备的距离。如果当前终端设备距离网络设备较远,则表示终端设备可能处于小区边缘。此时,如果终端设备没有满足退出DRX模式的触发条件,即终端设备没有满足小区切换或终端设备在无线资源控制连接(Radio Resource Control Connected,RRC_Connected)状态下因为信道环境较差的触发退出DRX模式的条件,则终端设备的信道质量波动和时延很大。此时,如果网络设备配置的CSI测量资源和上报资源少,则终端设备可能无法及时上报信道质量指示(Channel Quality Indication,CQI)进行调制与编码策略(Modulation and Coding Scheme,MCS)调整,网络设备的吞吐率性能会受一定程度影响。因此,网络设备可以根据终端设备与网络设备的距离进行CSI测量资源和上报资源的配置。在待配置的DRX周期开始之前,网络设备可以查询位置参数(例如DistBasedHO.DistBasedHOThd)来获取终端设备与网络设备的距离,确定上述距离所处的距离区间,在预设的资源配置表中查询与上述距离区间对应的资源配置信息。
在另一些可能的实现方式中,第一参数可以为当前终端设备的移动速度。如果终端设备的移动速度较高,且终端设备没有满足退出DRX模式的触发条件,则可能出现终端设备还没完成CSI测量,终端设备就已经离开原网络设备的覆盖范围的情况,从而导致终端设备网络切换失败和出现掉话情况。因此,可以将终端设备的移动速度进行CSI测量资源和上报资源的配置。如果终端设备的移动速度较快,则网络设备应当配置较多的CSI测量资源和上报资源,以指示终端设备尽快完成CSI测量和上报,减少网络切换失败和掉话情况;如果终端设备的移动速度较慢,则相对而言网络设备可以配置较少的CSI测量资源和上报资源。因此,网络设备在待配置的DRX周期开始之前,可以获取终端设备在速度测量周期内位置变化信息,根据上述位置变化信息计算终端设备当前的移动速度。网络设备获取到终端设备当前的移动速度之后,确定上述移动速度所处的速度区间,在预设的资源配置表中查询与上述速度区间对应的资源配置信息。
应当理解的是,上述关于第一参数的描述仅为本实施例中对第一参数的示意性举例,在其他的可能的实现方式中,第一参数还可以为上行调制编码方案(Modulation and Coding Scheme,MCS)索引、上行数据初传误包率(Initial Block Error Rate,IBLER)阈值、最大时间提前量(time advanced,TA)等与待配置的DRX周期有关的参数。第一参数的具体类型应当根据实际情况进行确定,上述示例不应理解为对第一参数的类型的限制。并且,在上述描述的内容中,虽然仅描述了第一参数为某一种参数的情形,但是第一参数可以为某一种参数,或者,第一参数可以为两种或两种以上的参数的集合。例如,第一参数可以为待配置的DRX周期的周期类型,网络设备在预设的资源配置表中查询与上述周期类型对应的资源配置信息;或者第一参数为待配置的DRX周期的周期类型与业务量的结合,网络设备在预设的资源配置表中查询与上述周期类型以及业务量所处的业务量区间对应的资源配置信息。
上述提及的资源配置信息可以包括CSI测量参考信号的时频位置、CSI测量参考信号的数目、CSI测量参考信号的周期、CSI上报资源的时频位置、CSI上报资源的数目、CSI上报资源的周期等配置参数中的一种或多种。
上述提及的CSI测量参考信号可以包括信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、时频域跟踪参考信号(Time/Frequency Tracking Signal,TRS)、解调参考信号(Demodulation Reference Signal,DM-RS)、同步信号块(Synchronization Signal Block,SSB)等信号中的一种或多种的组合。
上述提及的CSI可以包括信道质量指示(Channel Quality Indication,CQI)、预编码矩阵指示符(Precoding Matrix Indicator,PMI)、秩指示符(Rank Indicator,RI)、层指示符(Layer Indicator,LI)等信号中的一种或多种的组合。
上述提及的预设的资源配置表为用户预先设置的资源配置表。预设的资源配置表中记录着第一参数与资源配置信息的对应关系。可以理解的是,用户可以通过实验测试、理论计算等方式确定各第一参数对应的资源配置信息,从而得到第一参数与资源配置信息的对应关系,建立预设的资源配置表。
S102、网络设备将所述资源配置信息发送至终端设备,以指示所述终端设备根据所述资源配置信息进行信道状态信息的测量与上报。
网络设备从预设的资源配置表中查询到与上述第一参数对应的资源配置信息后,将上述资源配置信息发送至终端设备。
在一些可能的实现方式中,上述资源配置信息可以是具体的资源配置方案。网络设备将具体的资源配置方案发送至终端设备。
在另一些可能的实现方式中,上述资源配置信息可以是索引。终端设备上存储有资源配置信息索引表,网络设备将索引发送至终端设备后,终端设备可以根据索引从资源配置信息索引表中查询具体的资源配置方案。
在另一些可能的实现方式中,上述资源配置信息可以是索引和资源配置信息索引表的结合。网络设备将资源配置信息发送至终端设备后,终端设备获取资源配置信息中的索引和资源配置信息索引表,根据上述索引从资源配置信息索引表中查询具体的资源配置方案。
在一些可能的实现方式中,网络设备可以将上述资源配置信息以指示比特或信令消息的形式封装至物理下行控制信道(Physical Downlink Channel,PDCCH)中的下行信号中,通过PDCCH将下行信号发送至终端设备。
上述下行信号可以为下行控制信息(Downlink Control Information,DCI)、媒体接入控制控制单元(Media Access Control-Control Element,MAC-CE)、无线资源控制(Radio Resource Control,RRC)信令、参考信号指示信息等下行信号中的一种。
当采用DCI消息承载资源配置信息时,可以在现有的DCI消息中增加额外的指示比特。所增加的额外比特可以用于指示资源配置信息,也可以指示PoSS信号类型、DRX参数等信息。或者,也可以引入新的DCI消息,新的DCI消息中的指示比特可以用于指示资源配置信息,也可以指示PoSS信号类型、DRX参数等信息。
以图8所示的DCI消息为例。上述DCI消息包括N个域,每个域包括若干指示比特,一种K个指示比特。其中,N和K均为正整数。
上述DCI消息的指示比特可以用于指示资源配置信息,也可以指示PoSS信号类型(例如WUS信号、GTS信号)、DRX参数(例如DRX周期的周期长度、OnDuration长度)等信息。
如图9所示,假设资源配置信息包括CSI测量参考信号个数、测量参考信号周期、CSI上报资源个数、上报资源周期。此时DCI中域3中的指示比特表征的索引为S(0≤S≤L),则该指示比特表征的资源配置信息为CSI测量参考信号个数为mS,测量参考信号周期为tS,CSI上报资源个数为nS,上报资源周期为pS。
上述资源配置信息用于指示终端设备根据资源配置信息中关于CSI测量资源和上报资源的配置信息进行信道状态信息的测量与上报。
如图10所示,终端设备接收到网络设备发送的资源配置信息后,对资源配置信息进行解析,得到关于CSI测量资源和上报资源的配置信息。终端设备根据CSI测量资源的配置信息,使用一个或一个以上的CSI测量参考信号对信道状态信息进行测量。
终端设备完成信道状态信息的测量之后,可以根据CSI上报资源的配置信息执行上报操作,通过CSI上报资源将信道状态信息反馈至网络设备。
终端设备可以将CSI封装至物理上行控制信道(Physical Uplink Control Channel,PUCCH)中的上行信道控制信息(Uplink Control Information,UCI)、物理上行共享信道(Physical Uplink Shared Channel,PUSCH)中的部分承载信息等。
