Description

一种检测唤醒信号的方法和终端设备 技术领域
本申请涉及通信领域，更具体地，涉及通信系统中检测唤醒信号的方法和终端设备。
背景技术
物联网(internet of things，IoT)是一种面向机器类型通信(machine type communication，MTC)的网络，是未来通信领域的一类重要网络。物联网通信主要应用于智能抄表、医疗检测监控、物流检测、工业检测监控、车联网、智能社区以及可穿戴设备通信等。由于物联网应用场景多种多样，包括从室外到室内，从地上到地下，因而对物联网的设计提出了很多特殊的要求：
覆盖增强：许多IoT终端都处于覆盖较差的环境下，比如电表水表等，通常安装在室内甚至地下室等无线网络信号很差的地方，因此需要覆盖增强技术来解决差覆盖下的通信质量问题；
终端数量巨大：IoT设备的数量要远远大于人与人通信的设备数量；
业务速率需求低、时延不敏感：IoT设备传输的数据包一般较小，且对延时不敏感；
极低成本：许多IoT应用要求非常低的终端设备成本以便大规模部署；
低功耗：在大多数情况下，IoT设备通过电池来供电，并要求能够使用十年以上而不需要更换电池，这要求IoT设备能够以极低功耗来工作。
为了满足这些特殊需求，移动通信标准化组织第三代合作伙伴计划(3rd generation partnership project，3GPP)在全球移动通信系统(global system for mobile communications，GSM)/GSM演进增强数据速率(enhanced data rates for GSM evolution，EDGE)无线接入网(GSM/EDGE radio access network，GERAN)第62次会议上通过了一个新的研究课题，用来研究在蜂窝网络中支持极低复杂度和低成本的物联网的方法，并且在无线接入网(radio access network，RAN)第69次会议上立项为窄带物联网(narrow band internet of things，NB-IoT)课题。
在无线通信系统中，终端设备有两种状态，一种是连接态，表示终端设备已与网络设备建立了连接，可直接进行通信；一种是空闲态或称为睡眠态，终端设备无法与网络设备直接进行通信。空闲态的终端设备会定期醒来监听寻呼消息，看是否有自己的寻呼指示。终端设备醒来的位置叫寻呼机会(paging occasion，PO)，终端设备会在PO处监听窄带物理下行控制信道(narrow band physical downlink control channel，NPDCCH)。但在实际应用中，网络设备寻呼终端设备的概率和系统消息变更的概率一般都很低，故大部分PO可能是空的，即网络设备在PO处不发送相应的NPDCCH，但是终端设备依然需要在每个PO处监听NPDCCH，因为终端设备只有盲检完毕后才知道网络设备是否有发送NPDCCH，这其实是一种功耗的浪费。
针对上述问题，NB-IoT R15引入了唤醒信号(wake-up signal，WUS)，来指示终端 设备在PO位置是否需要被唤醒来接收和检测后续的NPDCCH。具体地，终端设备会在PO前检测唤醒信号，如果检测到WUS信号，则会检测后续的NPDCCH；如果没有检测到WUS信号，则不会检测后续的NPDCCH。
但是标准尚未规定WUS信号出现在哪里，在这种情况下终端需要通过多次盲检才能知道网络设备在哪里发送WUS信号，甚至不确定网络设备是否有发送WUS信号，这样会显著增加终端设备功耗。因此，如何减少因盲检消耗的终端设备的功耗是一个亟待解决的问题。

下面以LTE系统为例进行介绍。
图1是可以应用本申请的一种通信系统架构的示意图，如图1所示，网络设备和终端设备1～终端设备6组成一个通信系统。在该通信系统中，终端设备1～终端设备6可以发送上行数据给网络设备，网络设备需要接收终端设备1～终端设备6发送的上行数据，网络设备也可以发送下行数据给终端设备1～终端设备6。此外，终端设备4～终端设备6也可以组成一个通信系统，在该通信系统中，终端设备4和终端设备6可以发送上行数据给终端设备5，终端设备5也可以发送下行数据给终端设备4和终端设备6。
在无线通信系统中，终端设备有两种状态，一种是连接态，表示终端设备已与网络设备建立了连接，可直接进行通信；一种是空闲态或称为睡眠态，终端设备无法与网络设备直接进行通信。为了保证网络设备能够有效地找到空闲态的终端设备，网络设备一般会通过寻呼的方式，即定期地向终端设备发送寻呼信号，以指示终端设备是否应该从空闲态切换到连接态以便与网络设备进行通信。终端设备在没有业务发送或接收的时候，可以进入空闲态以降低耗电量。对于处在空闲态的终端设备，当网络设备要向终端设备发送业务或者需要终端设备上报一些业务的时候，可以通过寻呼机制通知终端设备，终端设备在接到寻呼通知后可以醒来进入连接态，以便发送或者接收业务数据。
图2是终端设备视角下的寻呼示意图。空闲态的终端设备会定期醒来监听寻呼消息，看是否有自己的寻呼指示，如图2所示，定期醒来的周期称为非连续接收(discontinuous reception，DRX)周期，DRX的周期可以由系统消息指示。终端设备醒来的位置叫PO(paging occasion，寻呼机会)，终端设备会在PO处监听NPDCCH。对于空闲态的终端设备，在 DRX周期内的绝大部分时间是休眠的，而只在对应的PO处醒来监听NPDCCH，终端设备在DRX周期内只需要检测一个PO。
在现有系统中，终端设备总是先检测目标搜索空间，确定是否有相应的下行调度(例如NPDCCH调度)：如果在目标搜索空间中检测到NPDCCH，则终端设备根据检测到的NPDCCH上承载的指示信息来接收窄带物理下行共享信道(narrow band physical downlink shared channel，NPDSCH)；如果在目标搜索空间中没有检测到NPDCCH，则终端设备不会接收NPDSCH。
终端设备一般会在NPDCCH目标搜索空间(search space)内以盲检的形式检测NPDCCH。NPDCCH目标搜索空间是指目标NPDCCH可能出现的备选位置(candidate)的集合，PO指示终端设备监听NPDCCH的起始位置，从而确定一个目标搜索空间的起始位置，根据该位置进行盲检。终端设备在以PO位置为起始位置的搜索空间中，依次盲检不同的备选位置，直到检测成功为止；如果都不成功，则认为网络设备没有发送NPDCCH。对于NB-IoT系统，NPDCCH的接收时间可能比较长，盲检测算法也比较复杂，因此终端设备在PO处监听NPDCCH是非常耗费功耗的。
因此，NB-IoT R15引入了唤醒信号(wake-up signal，WUS)，来指示终端设备在PO位置是否需要被唤醒来接收和检测后续的NPDCCH。具体地，在终端设备视角下，终端设备会在PO前检测唤醒信号，如果检测到WUS信号，则会检测后续的NPDCCH；如果没有检测到WUS信号，则不会检测后续的NPDCCH。图3是网络设备视角下寻呼指示信号示意图。如图3所示，在网络设备视角下，当PO上有NPDCCH时，例如需要寻呼终端设备或者系统消息发生变更，网络设备在PO前发送唤醒信号WUS；当PO上没有NPDCCH时，网络设备不发送任何信号，即非连续发送(discontinuous transmission，DTX)。
但是标准尚未规定WUS信号出现在哪里，在这种情况下终端设备需要通过多次盲检才能知道网络设备在哪里发送WUS信号，甚至不确定网络设备是否有发送WUS信号，这样会显著增加终端设备功耗。
本申请提供一种检测唤醒信号的方法和终端设备，能够使得终端设备确定检测唤醒信号的位置，从而降低终端设备的功耗。
图4是根据本申请实施例提供的一种检测唤醒信号的方法的示意性流程图。图4的方法可以由终端设备执行，包括以下内容中的至少部分内容。
在401中，终端设备向网络设备发送第一信息，该第一信息用于指示上报间隔。
在402中，该终端设备接收网络设备发送的第二信息。
在403中，该终端设备根据该第二信息确定第一间隔的配置情况和第二间隔的配置情况。
在404中，该终端设备根据该上报间隔、该第一间隔的配置情况和该第二间隔的配置情况，确定目标间隔。
在405中，该终端设备在寻呼时间窗口PTW中首个寻呼机会PO的起始位置之前的检测位置处检测唤醒信号，该检测位置由该目标间隔与该唤醒信号的最大持续时间确定。
上述技术方案终端设备通过上报间隔、第一间隔的配置情况和第二间隔的配置情况，确定目标间隔，结合唤醒信号的预设的最大持续时间，进而确定检测唤醒信号的位置，可以避免终端设备盲检唤醒信号，从而降低终端设备的功耗。
下面分别对401-405进行详细描述。
在401中，终端设备向网络设备发送第一信息，该第一信息用于指示上报间隔。
在检测WUS时，终端设备可以只需要做序列相关，因此可以关闭大部分电路以省功耗。
当检测到WUS后，终端设备才需打开其他电路、加载内存等，进而去解调PO上的NPDCCH，而这需要一定时间(warm up time)。
可选地，上报间隔为打开其他电路、加载内存等需要的这段时间。
例如，上报间隔为40ms，表示认为终端设备在检测到WUS后，至少需要40ms才能完成“打开其他电路、加载内存等”准备工作，才能去解调PO上的NPDCCH。
因此，上报间隔可以反应终端设备能力。一般来讲，上报间隔越大，表示终端设备能力越弱(加载内存比较慢)。
可选地，终端设备为具备扩展的非连续接收(extend discontinuous reception，eDRX)配置的终端设备。
可选地，具有eDRX配置的终端设备可以处于eDRX状态。
首先，对于不具备eDRX配置的终端设备，终端设备在PO之外的时间处于浅睡眠(light sleep)，可以关闭大部分电路，以节省功耗；终端设备周期性的醒来去检测PO，该周期称为DRX周期(DRX cycle)，例如，DRX周期取值可以是{1.28s,…,10.24s}。
因此，对于不具备eDRX配置的终端设备至少10.24s需要醒来一次(因为DRX周期最大为10.24s)。
相较于不具备eDRX配置的终端设备，具备eDRX配置的终端设备在时域上有一个寻呼时间窗口(paging time window，PTW)，如图5所示。具有eDRX配置的终端设备只在PTW内部醒来，PTW内部的行为与不具备eDRX配置的终端设备一致。PTW周期最大为2.9h，意味着具备eDRX配置的终端设备可以每2.9h才醒来一次。
终端设备在PTW外处于深睡眠(deep sleep)状态，深睡眠状态比浅睡眠状态相比可以关闭更多的电路，所以eDRX是比DRX更省电的状态。
同样，eDRX检测到WUS后也需要更长的warm up time(对应更长的WUS gap)。
应理解，PTW中首个寻呼机会前的唤醒信号可以在PTW中，也可以在PTW外。
对于具有eDRX配置的终端设备，终端设备一定会上报一个唤醒信号间隔(WUS gap或WUS offset)。如图3所示，唤醒信号间隔为唤醒信号的预设的最大持续时间(configured maximum WUS duration)结束处于PO起始处之间的间隔。
可选地，上报间隔为唤醒信号间隔。
可选地，该唤醒信号间隔的取值范围可以是{40ms,240ms,1s,2s}。
例如，具有eDRX配置的终端设备上报240ms，表示终端设备认为自己需要240ms才能完成warm up操作。
这里需要说明的是，如果终端设备上报1s、2s，则很大概率表示终端设备有WUS专用检测电路。终端设备可以完全关闭以前的主电路、只打开WUS专用检测电路来检测WUS，当检测到WUS后，终端设备才去打开主电路，以实现超低功耗。
所以，上报1s、2s的终端设备并不一定比上报40ms、240ms的终端设备能力弱，很有可能表示该终端设备有额外的WUS专用检测电路。
由于此时主电路被完全关闭，所以终端设备需要更长的warm up time，因此标准定义了1s、2s。
应理解，终端设备向网络设备上报唤醒信号间隔，也就是向网络设备上报至少需要多久终端设备可以完成准备工作。
可选地，该唤醒信号的最大持续时间可以是网络设备提前通知给终端设备的。
此外，对于不具有eDRX配置的终端设备，终端设备则不会上报唤醒信号间隔。
在402中，该终端设备接收网络设备发送的第二信息；
可选地，网络设备发送第二信息可以以广播的形式。
例如，网络设备在小区内向小区中的终端设备发送广播信息，第二信息可以为该广播信息。
在403中，该终端设备根据该第二信息确定第一间隔的配置情况和第二间隔的配置情况。
可选地，网络设备可以根据小区内多个终端设备上报的多个上报间隔，为该多个终端设备配置同一个第一间隔或第二间隔。
可选地，网络设备可以根据小区内多个终端设备上报的多个上报间隔，为该多个终端设备配置不同的第一间隔或第二间隔。
可选地，第一间隔可以等于上报间隔。
可选地，第一间隔也可以不等于上报间隔。
也就是说，网络设备为终端设备配置的第一间隔不一定等于终端设备上报的上报间隔，第一间隔取决于网络设备的实现。
例如，一个小区内可能有成百上千个终端设备，每个终端设备上报不同的上报间隔，网络设备无法匹配所有终端设备的需求。
可选地，终端设备为具备eDRX配置的终端设备。
网络设备一定会为具备eDRX配置的终端设备配置一个eDRX短间隔。
可选地，第一间隔可以是eDRX短间隔。
可选地，eDRX短间隔的取值范围可以是{40ms，80ms，160ms，240ms}。
也就是说该第一间隔的配置情况可以包括：第一间隔配置为40ms、第一间隔配置为80ms、第一间隔配置为160ms和第一间隔配置为240ms。
此外，对于不具备DRX配置的终端设备，网络设备一定会为终端设备配置一个DRX间隔(DRX gap或者DRX offset)。
可选地，DRX间隔的取值范围可以是{40ms，80ms，160ms，240ms}
可选地，eDRX短间隔大于或者等于DRX间隔。
例如，当DRX间隔等于40ms时，eDRX短间隔的取值范围可以是{80ms，160ms，240ms}。
DRX间隔、eDRX短间隔和eDRX长间隔的关系如图6所示。可选地，该第二间隔可以为eDRX长间隔。
可选地，该第二间隔的配置情况可以包括：未配置第二间隔、第二间隔配置为1s和第二间隔配置为2s。
也就是说，网络设备有可能会具备eDRX配置的终端设备配置一个eDRX长间隔。
在404中，该终端设备根据该上报间隔、该第一间隔的配置情况和该第二间隔的配置情况，确定目标间隔。
该目标间隔为终端设备检测唤醒信号和网络设备发送唤醒信号实际使用的唤醒信号间隔。
可选地，在该上报间隔为1s、该第一间隔配置为40ms且未配置该第二间隔情况下，确定该目标间隔为40ms。
可选地，在该上报间隔为1s、该第一间隔配置为40ms且未配置该第二间隔情况下，该目标间隔由该第一间隔(也即eDRX短间隔)确定。
例如，目标间隔可以为eDRX短间隔的1/2倍、2倍等，也即为20ms、80ms等。
可选地，在该上报间隔为1s、该第一间隔配置为80ms且未配置该第二间隔情况下，确定该目标间隔为80ms。
可选地，在该上报间隔为1s、该第一间隔配置为80ms且未配置该第二间隔情况下，该目标间隔由该第一间隔(也即eDRX短间隔)确定。
例如，目标间隔可以为eDRX短间隔的1/2倍、2倍等，也即为40ms、160ms等。

可选地，在该上报间隔为1s、该第一间隔配置为160ms且未配置该第二间隔情况下，该目标间隔由该第一间隔(也即eDRX短间隔)确定。
例如，目标间隔可以为eDRX短间隔的1/2倍、2倍等，也即为80ms、320ms等。
可选地，在该上报间隔为1s、该第一间隔配置为240ms且未配置该第二间隔情况下，确定该目标间隔为240ms。
可选地，在该上报间隔为1s、该第一间隔配置为240ms且未配置该第二间隔情况下，该目标间隔由该第一间隔(也即eDRX短间隔)确定。
例如，目标间隔可以为eDRX短间隔的1/2倍、2倍等，也即为80ms、480ms等。
通过上述技术方案，终端设备可以确定检测唤醒信号的位置，可以避免终端设备盲检唤醒信号，从而降低终端设备的功耗。
此外上述技术方案中，在上报间隔为1s且网络设备未配置eDRX长间隔时，目标间隔为eDRX短间隔，相较于目标间隔为DRX间隔时，终端设备可以在eDRX状态下检测唤醒信号，这样可以尽可能延长终端设备处于eDRX状态的时间，从而进一步降低终端设备功耗。
可选地，在该上报间隔为2s、该第一间隔配置为40ms且未配置该第二间隔情况下，确定该目标间隔为40ms。
可选地，在该上报间隔为2s、该第一间隔配置为40ms且未配置该第二间隔情况下，该目标间隔由该第一间隔(也即eDRX短间隔)确定。

此外上述技术方案中，在上报间隔为2s且网络设备未配置eDRX长间隔时，目标间隔为eDRX短间隔，相较于目标间隔为DRX间隔时，终端设备可以在eDRX状态下检测唤醒信号，这样可以尽可能延长终端设备处于eDRX状态的时间，从而进一步降低终端设备功耗。

在405中，该终端设备在寻呼时间窗口PTW中首个寻呼机会PO的起始位置之前的检测位置处检测唤醒信号，该检测位置由该目标间隔与该唤醒信号的最大持续时间确定。
可选地，该检测位置为在寻呼时间窗口PTW中首个寻呼机会PO的起始位置之前，与PO相隔目标间隔与该唤醒信号的最大持续时间之和的位置。
例如，假设PO起始位置为T，目标间隔＝40ms，WUS最大持续时间＝128ms，检测位置为T-40-128处。
可选地，该检测位置有该目标间隔、该唤醒信号的最大持续时间和延迟信息确定。
例如，在NB-IoT中有一些子帧是无效子帧、或者用于传输广播信号、同步信号的子帧，WUS遇到这些子帧会采取延迟的方式，即该子帧不能用于WUS传输，也不计数，即跳过去。假设PO起始位置为T，目标间隔＝40ms，WUS最大持续时间＝128ms，在128ms内有10个上述子帧，那么检测位置为T-40-128-10处。

在701中，网络设备接收终端设备发送的第一信息，该第一信息用于指示上报间隔。
可选地，上报间隔为打开其他电路、加载内存等需要的这段时间。

对于网络设备的12种配置，其中40ms代表网络设备为终端设备配置一个eDRX短间隔＝40ms，未配置eDRX长间隔，其他类似形式的第二间隔含义类似；40ms+1s代表网络设备为终端设备配置一个eDRX短间隔＝40ms和一个eDRX长间隔＝1s，其他类似形式的配置含义类似。

终端设备上报值＝40ms，网络设备为eDRX配置的值＝240ms时，表示终端设备上报WUS gap＝40ms，网络设备只配置了eDRX短间隔＝240ms、未配置eDRX长间隔，这种情 况下，该终端设备对应的WUS gap＝240ms，即网络设备在240ms+128ms处发该终端设备的WUS、终端设备在240ms+128ms检测WUS。
终端设备上报值＝40ms，网络设备为eDRX配置的值＝240ms+1s时，表示终端设备上报WUS gap＝40ms，网络设备配置了eDRX短间隔＝240ms、额外配置了eDRX长间隔＝1s，这种情况下，该终端设备对应的WUS gap＝240ms，即网络设备在240ms+128ms处发该终端设备的WUS、终端设备在240ms+128ms检测WUS。
终端设备上报值＝1s,网络设备为eDRX配置的值＝240ms+1s时，表示终端设备上报WUS gap＝1s(表示终端设备很可能有WUS专用检测电路)，网络设备配置了eDRX短间隔＝240ms、额外配置了eDRX长间隔＝1s，这种情况下，该终端设备对应的WUS gap＝1s，即网络设备在1s+128ms处发该终端设备的WUS、终端设备在1s+128ms检测WUS。
终端设备上报值＝1s,网络设备为eDRX配置的值＝80ms时，表示终端设备上报WUS gap＝1s，网络设备配置了eDRX短间隔＝80ms、未配置了eDRX长间隔，这种情况下，该终端设备对应的DRX gap＝40ms，即网络设备在DRX gap+128ms＝40ms+128ms处发该终端设备的WUS、终端设备在DRX gap+128ms＝40ms+128ms检测WUS，如图8所示。
表格中其他情况的含义类似。

同样以检测位置为在寻呼时间窗口PTW中首个寻呼机会PO的起始位置之前，与PO相隔目标间隔与该唤醒信号的预设的最大持续时间之和的位置为例。
假设网络设备此时配置的DRX gap＝40ms，唤醒信号最大持续时间为128ms。
其中，终端设备上报值＝40ms，网络设备为eDRX配置的值＝240ms时，表示终端设备上报WUS gap＝40ms，网络设备只配置了eDRX短间隔＝240ms、未配置eDRX长间隔，这种情况下，该终端设备对应的WUS gap＝240ms，即网络设备在240ms+128ms处发该终端设备的WUS、终端设备在240ms+128ms检测WUS。
终端设备上报值＝40ms,网络设备为eDRX配置的值＝240ms+1s时，表示终端设备上报WUS gap＝40ms，网络设备配置了eDRX短间隔＝240ms、额外配置了eDRX长间隔＝1s，这种情况下，该终端设备对应的WUS gap＝240ms，即网络设备在240ms+128ms处发该终端设备的WUS、终端设备在240ms+128ms检测WUS。

上述技术方案中，终端设备通过上报间隔、第二间隔和第二间隔，确定目标间隔，结合唤醒信号的最大持续时间，进而确定检测唤醒信号的位置，可以避免终端设备盲检唤醒信号，从而降低终端设备的功耗。
此外，上述技术方案中，上报间隔为1s或者2s且网络设备未配置eDRX长间隔时，目标间隔为eDRX短间隔，相较于目标间隔为DRX间隔(终端设备需要从eDRX状态切换到DRX状态来检测WUS，终端设备功耗增加。具体而言，如果该PO上没有paging(即 网络设备没有发送WUS)，终端设备本可以一直在eDRX状态，即终端设备行为是：eDRX状态→检测WUS→未检测到WUS→继续处于eDRX状态；而当目标间隔为DRX间隔时，终端设备需从eDRX状态切换至DRX状态来检测WUS，处于eDRX状态的时长变短，终端设备功耗增加，即终端设备行为变为了：eDRX状态→DRX状态→检测WUS→未检测到WUS→DRX状态)时，终端设备可以在eDRX状态下检测唤醒信号，这样可以尽可能延长终端设备处于eDRX状态的时间，从而进一步降低终端设备功耗。
