Description

监听或发送唤醒信号的方法和装置及通信设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及监听或发送唤醒信号的方法和装置及通信设备。
背景技术
目前，已知一种寻呼机制，终端设备会在对应的寻呼时刻，或者说，寻呼机会(paging occasion，PO)之前检测唤醒信号(wake up signal，WUS)，如果检测到WUS则在PO检测寻呼消息，如果未检测到WUS，则在PO休眠。
根据该现有技术，对于包括多个终端设备的PO，如果该PO内存在需要被寻呼的终端设备(记做，终端设备#a)，则需要发送该PO对应的WUS。
此情况下，如果该PO内存在不需要被寻呼的终端设备(记做，终端设备#b)，则该终端设备#b由于检测到WUS，因此会在PO内唤醒，从而导致终端设备#b的功耗增加。
因此，希望提供一种技术，能够降低终端设备的功耗。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通信(global system for mobile communications，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、 通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
作为示例而非限定，本申请实施例的技术方案可以应用于物联网(internet of things，IoT)系统、机器类型通信(machine type communication，MTC)系统，或者说，机器对机器(machine to machine，M2M)系统。
IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
在本申请实施例中，IOT技术可以通过例如窄带(narrow band)NB技术，做到海量连接，深度覆盖，终端省电。例如，NB只包括一个资源块(resource block，RB)，即，NB的带宽只有180kHz。要做到海量接入，必须要求终端在接入上是离散的，根据本申请实施例的通信方法，能够有效解决IOT技术海量终端在通过NB接入网络时的拥塞问题。
MTC狭义上的定义是机器到机器的通信，广义上的定义是以机器终端智能交互为核心的网络化的应用与服务。MTC是基于智能机器终端，以多种通信方式为接入手段，为客户提供的信息化解决方案，用于满足客户对监控、指挥调度、数据采集和测量等方面的信息化需求。
IoT和MTC可以应用于行业应用、家庭应用、个人应用等。行业应用如交通监控、告警系统、海上救援、自动售货机、开车付费等。家庭应用如自动抄表、温度控制等。个人应用如生命检测、远端诊断等。
IoT和MTC有别于传统LTE通信，其不追求数据传输速率、多频段、多天线、全双工传输，而是追求较长的终端装置电池时间，较低廉的终端装置成本，即要求终端能够实现低功耗(low power consumption)、低成本(low cost))，此外，考虑到IoT和MTC的终端的应用场景，例如水表、电表等，终端的信号覆盖强度无法满足信号接收要求，因此对MTC进行增强，使基站和终端能够支持扩展覆盖(coverage enhancement)，目前实现扩展覆盖的主要方法是重复多次发送上行或下行信号，通过多次接收合并实现提高数据接收成功率的目的。此外，在MTC或IoT的应用场景中，数据传输的特点是数据量较小，且数据到达时间不确定。例如，网络侧呼叫终端上报数据，或是网络侧向终端下达控制指令等。现有技术中，为了传输数据，需要建立起基站与终端之间的无线连接，而建立该无线连接需要一定的信令开销，如果只是为了传输较小的数据，沿用现有技术中的连接建立流程，会使得无线资源的利用效率降低，大量资源用于连接建立的流程，少量资源用于数据传输。
根据本申请提供的方案能够有效降低终端设备的功耗，从而能够满足MTC或IoT的应用场景中对降低终端设备功耗的要求。
作为示例而非限定，在本申请实施例中，本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop， WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网系统中的终端设备，或者，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通信(global system for mobile communications，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolved NodeB，eNB或eNodeB)，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，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，可以是WLAN中的接入点(access point，AP),可以是新型无线系统(new radio，NR)系统中的gNB本申请实施例并不限定。
另外，在本申请实施例中，接入网设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与接入网设备进行通信，该小区可以是接入网设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
此外，LTE系统或5G系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如在载波聚合(carrier aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(cell indentification，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。
此外，在本申请中，网络设备可以包括基站(gNB)，例如宏站、微基站、室内热点、以及中继节点等，功能是向终端设备发送无线电波，一方面实现下行数据传输，另一方面发送调度信息控制上行传输，并接收终端设备发送的无线电波，接收上行数据传输。
其中，以上列举的终端设备、接入网设备和核心网设备的功能和具体实现方式仅为示例性说明，本申请并未限定于此。

另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
需要说明的是，在本申请实施例中，在应用层可以运行多个应用程序，此情况下，执行本申请实施例的通信方法的应用程序与用于控制接收端设备完成所接收到的数据所对应的动作的应用程序可以是不同的应用程序。
图1是能够适用本申请实施例通信方法的系统100的示意图。如图1所示，该系统100包括接入网设备102，接入网设备102可包括1个天线或多个天线例如，天线104、106、108、110、112和114。另外，接入网设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
接入网设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，接入网设备102可以与类似于终端设备116或终端设备122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路(也称为下行链路)118向终端设备116发送信息，并通过反向链路(也称为上行链路)120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(frequency division duplex，FDD)系统中，例如，前向链路118 可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(time division duplex，TDD)系统和全双工(full duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为接入网设备102的扇区。例如，可将天线组设计为与接入网设备102覆盖区域的扇区中的终端设备通信。接入网设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在接入网设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，接入网设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与接入网设备通过单个天线或多天线发射分集向它所有的终端设备发送信号的方式相比，在接入网设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，接入网设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络、设备到设备(device-to-device，D2D)网络、机器到机器(machine to machine，M2M)网络、IoT网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他接入网设备，图1中未予以画出。
在本申请实施例中，数据或信息可以通过时频资源来承载，其中，该时频资源可以包括时域上的资源和频域上的资源。其中，在时域上，时频资源可以包括一个或多个时间单元。
其中，一个时间单元可以是一个符号，或者一个迷你时隙(Mini-slot)，或者一个时隙(slot)，或者一个子帧(subframe)，其中，一个子帧在时域上的持续时间可以是1毫秒(ms)，一个时隙由7个或者14个符号组成，一个迷你时隙可以包括至少一个符号(例如，2个符号或4个符号或者7个符号，或者小于等于14个符号的任意数目符号)。
本申请提供的方案可以应用于对终端设备的寻呼过程。
在移动通信中，可以通过寻呼来实现指示处于空闲态(idle)的终端设备发起和网络侧之间的连接、或指示处于空闲态的终端设备根据网络侧的指示进行其它的处理(例如，更新小区的系统消息)。
具体的说，终端设备可以包括两种状态，即，空闲态和连接态(connected)。
网络设备(例如，核心网设备或接入网设备)可以对空闲态和连接态的终端设备进行寻呼。
其中，该寻呼的过程可以有核心网设备触发，即，通知终端设备接收寻呼请求。
或者，该寻呼过程可以有接入网设备触发，用于通知终端设备更新系统信息，或者，通知终端设备接收地震和海啸预警系统(earthquake and tsunami warning system，ETWS)消息或商用移动警报系统(commercial mobile alert system，CMAS)消息等。
终端设备接收到的寻呼消息中如果携带有用户标识(UE ID)列表，则终端设备需要 将UE ID列表中的UE ID与终端设备自身的UE ID进行对比，以判定该寻呼消息是否是在呼叫该终端设备，即，如果该终端设备自身的UE ID在该UE ID列表中，则标识该寻呼消息呼叫该终端设备；如果该终端设备自身的UE ID不在该UE ID列表中，则标识该寻呼消息不是呼叫该终端设备。
另外，寻呼消息中可以包括寻呼标识(paging ID)。
其中，如果该paging ID为例如，系统架构演进临时移动用户标识(system architecture evolution temporary mobile subscriber identity，S-TMSI)，则标识本次寻呼是正常的业务呼叫。
或者，如果该paging ID为例如，国际移动用户标识号(international mobile subscriber identity，IMSI)，则标识本次寻呼是异常的呼叫，用于网络侧的错误恢复，并且，例如，此情况下，终端设备可以重新进行附着(attach)过程。
作为示例而非限定，承载寻呼消息的信道可以为寻呼控制信道(paging control channel，PCCH)，其中，该PCCH为逻辑信道。PCCH的数据块可以由寻呼信道(paging channel，PCH)承载，该PCH为传输信道。并且，该PCH承载于物理下行数据信道(physical downlink shared channel，PDSCH)。由于该PDSCH还可以承载下行数据，因此，在接收寻呼消息之前，终端设备可以监听物理下行控制信道(physical downlink control channel，PDCCH)，并根据该PDCCH是否携带该终端设备的寻呼移动网络临时标识(paging radio network temporary identifier，P-RNTI)的情况，判定本次寻呼周期(具体地说，是本次寻呼周期的PDSCH)中是否包括发送给该终端设备的寻呼消息，即，如果该PDCCH中携带有P-RNTI，则表示本次寻呼周期包括发送给该终端设备的寻呼消息；如果该PDCCH中未携带有P-RNTI，则表示本次寻呼周期不包括发送给该终端设备的寻呼消息。
在本申请中，为了减小终端设备的功耗，可以采用非连续接收(discontinuous reception，DRX)技术，即，在DRX模式下，终端设备可以周期性的在某些时段进入睡眠状态(sleep mode)，不去监听承载物理下行控制信道(physical downlink control channel，PDCCH)的子帧，而需要监听的时候，则从睡眠状态中唤醒(wake up)，这样就能够使UE到达省电的目的。
此情况下，终端设备在一个DRX周期内，可以只在对应的寻呼无线帧(paging frame，PF)上的寻呼机会(paging occasion，PO)监听P-RNTI加扰的PDCCH，进而去判断该PDCCH指示的PDSCH上是否承载寻呼消息。例如，如果在PDCCH上携带有P-RNTI，则按照PDCCH上指示的PDSCH的参数去接收PDSCH上的数据，进而获得寻呼消息；如果终端设备在PDCCH上未解析出P-RNTI，则无需接收PDSCH，并可以按照DRX周期进入休眠。
即，通过上述机制，在一个DRX周期内，终端设备可以只在PO出现的时间位置上去接收PDCCH，然后再根据PDCCH是否携带P-RNTI的情况去接收PDCCH，从而能够达到降低终端设备的功耗的目的。
在本申请中，终端设备和网络设备(例如，接入网设备或核心网设备)可以基于以下方法确定终端设备的PO。
例如，终端设备可以首先确定需要监听的PDCCH所承载于的无线帧的帧号，即，PF。然后确定PF上的PO。
作为示例而非限定，在本申请中可以基于以下公式1，确定PF：
SFN mod T＝(T/S)×(K mod S)      公式1
即，满足公式1的SFN指示的无线帧均可以作为PF。
其中，SFN为系统帧号，作为示例而非限定，SFN的取值范围可以是[0，1023]。
T表示DRX参数，作为示例而非限定，网络设备可以在系统消息，例如，SIB2中广播该参数，并且，例如，该T的取值可以包括但不限于32、64、128或256等，其中，T的单位可以是无线帧。
并且，S的取值可以是T和nB中的最小值，nB可以是网络设备在系统消息，例如SIB2中广播的参数，该nB的取值可以包括但不限于4T、2T、T、T/2、T/4、T/8、T/16或T/32，其中，S和nB的单位可以是无线帧。
K为终端设备的设备标识，或者，K为终端设备的设备标识对应的数值。
例如，K＝Q mod 1024，其中，Q可以为终端设备的IMSI。
在本申请中，PO可以是终端设备需要监听的PDCCH在PF上的子帧号。
即，终端设备和网络设备可以计算出该终端设备的PO在PF上的位置D，进而可以根据该D与PO的对应关系确定出PO。
作为示例而非限定，在本申请中可以基于以下公式2，确定D。
D＝floor(K/S)mod nS       公式2
其中，nS可以为1和nB/T中的最大值。例如，根据上述公式1中对nB的解释，nS的取值可以包括但不限于1、2或4。
即，在本申请中，D的取值范围可以包括但不限于0、1、2或3。
以下表1示出了本申请的D与PO的对应关系的一例。
表1
nS 当D＝0时PO的值 当D＝1时PO的值 当D＝2时PO的值 当D＝4时PO的值
1 0 不可用(N/A) N/A N/A
2 0 5 N/A N/A
4 0 1 5 6
为了降低终端设备的功耗，可以引入唤醒机制，即，终端设备可以在如上所述确定的PO之前，检测唤醒信号(wake up signal，WUS)，如果检测到WUS则在PO检测寻呼消息，如果未检测到WUS，则在PO休眠。
根据该现有技术，对于包括多个终端设备的PO，如果该PO内存在需要被寻呼的终端设备(记做，终端设备#a)，则需要发送该PO对应的WUS。
此情况下，如果该PO内存在不需要被寻呼的终端设备(记做，终端设备#b)，则该终端设备#b由于检测到WUS，因此会在PO内唤醒，从而导致终端设备#b的功耗增加
对此，在本申请中，可以将同一PO内的多个终端设备划分为多个(例如，U个)终端设备组，并且，如图2所示，每个终端设备组可以对应一个WUS，或者说，每个终端设备组可以对应一个承载WUS的时频资源，其中，各终端设组与各WUS之间的映射关系可以由通信系统或通信协议规定，或者，各终端设组与各WUS之间的映射关系可以由网络设备配置。
从而，一个终端设备可以确定其所属于的终端设备组，并在该终端设备组对应的时频 资源上检测WUS。
下面，结合图2和图3对上述终端设备组的确定该过程进行详细说明。
图2示出了网络设备#A(例如，接入网设备)与终端设备#A之间的唤醒信号传输方法200的一例的示意性流程。
如图2所示，在S210，终端设备#A可以获取该终端设备#A的寻呼特征信息，以下，为了便于理解，记做：寻呼特征信息#A。

作为实例而非限定，在本申请中，该寻呼特征信息#A可以根据该终端设备#A的功能确定，例如，在本申请中，该终端设备#A可以为MTC或IoT中的终端设备，例如，智能水表或智能电表等，由于该终端设备的功能简单，且业务访问时间固定，因此，制造商或运营商可以根据实验或历史数据确定该寻呼特征信息，并且，可以在该终端设备出厂或入网时将该寻呼特征信息下发至终端设备。
应理解，以上列举的终端设备#A确定寻呼特征信息#A的方法和过程仅为示例性说明，本申请并未限定于此，其他能够使终端设备#A确定寻呼特征信息#A的方法和过程均落入本申请的保护范围内。

例如，R＝2时，该2个终端设备组可以包括寻呼特征对应的数值高(例如，业务频繁到达而使业务到达率高于预设门限)的终端设备组，例如，该终端设备组的索引可以为“0”，并且，该2个终端设备组可以包括寻呼特征对应的数值低(例如，业务偶尔到达而使业务到达率低于预设门限)的终端设备组，例如，该终端设备组的索引可以为“1”。

作为实例而非限定，在本申请中，网络设备可以基于以下任意一种方式确定终端设备组#A。
方式3
