Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
在窄带物联网(narrow band internet of things，NB-IoT)系统中，网络设备定期发送寻呼信号(paging)，指示终端设备是否应该从空闲态切换到连接态，以便与终端设备交互业务数据。处于空闲态的终端设备定期醒来检测寻呼信号，定期醒来的周期称为非连续接收(discontinuous reception，DRX)周期，醒来的位置称为寻呼机会(paging occasion，PO)。终端会在PO位置起始的搜索空间内进行盲检，如果盲检到窄带物理下行控制信道(narrowband physical downlink control channel，NPDCCH)，则确定需要切换到连接态，否则保持空闲态。
在实际应用中，网络设备寻呼终端设备的概率一般很低，因此为了降低终端设备定期检测寻呼信号的频率，网络设备在PO位置前可以通过发送唤醒信号(wake up signal，WUS)序列，以指示终端设备是否需要在PO位置处醒来。当PO上有NPDCCH时，网络设备在PO前发送唤醒信号序列，以指示终端设备需要在PO位置处醒来；当PO上没有NPDCCH时，网络设备不发送唤醒信号序列。相应的，在PO前，如果终端设备检测到唤醒信号序列，则会在PO位置开始时盲检NPDCCH；如果没有检测到唤醒信号序列，则不会在PO位置开始时盲检NPDCCH。
在NB-IoT R15中，在PO之前定义了一个预设资源用于发送唤醒信号序列。而在NB-IoT R16中，在PO之前定义了两个预设资源用于发送唤醒信号序列，这两个预设资源都用于发送组唤醒信号序列和公共唤醒信号序列，其中的第一预设资源与NB-IoT R15中定义的预设资源相同，第二预设资源是在NB-IoT R15的基础上新增加的资源。目前网络侧不确定选择哪个预设资源为该终端设备发送组唤醒信号序列和公共唤醒信号序列，相应地，该终端设备也不确定选择哪个预设资源监听组唤醒信号序列和公共唤醒信号序列。
发明内容

具体实施方式
下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例可以应用于NB-IoT以及增强型机器类通信(enhanced machine type of communication，eMTC)、新无线(new radio，NR)系统、全球移动通讯(global system of mobile communication，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、长期演进(long term evolution，LTE)系统、先进的长期演进(advanced long term evolution，LTE-A)系统等其它通信系统，具体的，在此不做限制。本申请实施例中部分场景以NB-IoT网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的通信方法的通信系统的示意图。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，网络设备也可以向终端设备1～终端设备6发送下行数据。此外，终端设备4～终端设备6也可以组成一个通信系统，此时在该通信系统中，网络设备可以将终端设备4、终端设备6的下行数据发送至终端设备5，终端设备5再转发给终端设备4、终端设备6。
本申请实施例中，终端设备，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、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、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(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、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、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)中的无线终端等。
网络设备，可以是LTE系统中的演进型基站(evolutional node B，eNB)，可以是全球移动通讯(global system of mobile communication，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)等。
目前，在NB-IoT系统中，一个PO之前的一个间隙(gap)可以包括至少两个用于发送唤醒信号序列的预设资源，其中间隙为至少一个预设资源中，与PO最近的预设资源的结束位置，与PO的起始位置之间的时间长度。举例来说，如图2所示，图2中的PO之前，间隙1对应两个预设资源，这两个预设资源为NB-IoT R16中定义的资源。需要说明的是，在NB-IoT R15中，只定义了图2中与PO距离较近的预设资源。网络设备可以在这两个预设资源中都发送唤醒信号序列，也可以只在其中一个预设资源中发送唤醒信号序列。
唤醒信号序列包括两种，一种可以称为公共(common)唤醒信号序列，一种可以称为组(group)唤醒信号序列。公共唤醒信号序列可以唤醒所有终端设备，即任一终端设备接收到公共唤醒信号序列时，需要在PO位置醒来。组唤醒信号序列对应一组终端设备，该对应关系为预先建立的，组唤醒信号序列只可以唤醒一组终端设备。终端设备在接收到不是与该终端设备所处的组对应的组唤醒信号序列时，忽略该组唤醒信号序列，不在PO位置醒来。在NB-IoT R15中定义的预设资源上，可能会将R15唤醒信号序列作为公共唤醒信号序列。如果终端设备为支持NB-IoT R16的终端设备，当该终端设备一直监听NB-IoT R15中定义的预设资源时，会由于不断接收到公共唤醒信号序列而被唤醒，而实际上该终端设备可能并不需要被唤醒。因此如何降低终端设备被错误唤醒的几率，还没有确定的解决方案。
需要说明的是，一个PO之前可以存在多个间隙，每个间隙对应至少两个预设资源。举例来说，如图3所示，图3中的PO之前包括3个间隙，分别为间隙1、间隙2以及间隙3，每个间隙对应两个预设资源。
结合前面的描述，如图4所示，为本申请实施例提供的一种通信方法流程示意图。图4中，第一设备可以为终端设备，第二设备可以为网络设备，在本申请实施例中，第一设备和第二设备也可以均为终端设备。进一步的，第一设备可以为支持NB-IoT R15或NB-IoT  R16的终端设备。参见图4，该方法包括：
步骤401：第二设备根据第一预设规则，从第一寻呼机会PO之前的同一间隙对应的至少两个预设资源中确定第一资源；
步骤402：第二设备在所述第一资源中向第一设备发送唤醒信号序列。
步骤403：第一设备根据第一预设规则，从第一寻呼机会PO之前的同一间隙对应的至少两个预设资源中确定第一资源；
步骤404：第一设备在所述第一资源中监听至少一个唤醒信号序列。
其中，至少一个唤醒信号序列的数量为L，L的取值并不限定，例如可以为3或4。L的取值可以为发送所述至少一个唤醒信号序列的第二设备配置的，也可以通过其他方式约定，在此不再赘述。
通过上述方法，第一设备监听唤醒信号序列的第一资源，是根据第一预设规则确定的，因此可以避免第一设备始终在一个资源上监听唤醒信号序列，由于经常接收到公共唤醒信号序列而被不必要的唤醒，导致第一设备被唤醒的虚警概率很高。
本申请实施例中，第一设备根据所述第一预设规则在不同PO之前确定的资源的资源索引值不同或相同，或者，第一设备根据所述第一预设规则在连续K个PO之前确定的K个资源的K个资源索引值中，存在不相同的资源索引值，K为大于1的整数；所述资源索引值用于指示所述资源位于该PO之前的同一间隙对应的至少两个预设资源中的位置。
举例来说，结合图2所示，可以预先为每个PO之前的预设资源设置资源索引值，例如距离PO较远的预设资源的资源索引值为0，即预设资源1的资源索引值为0；距离PO较近的预设资源的资源索引值为1，即预设资源2的资源索引值为1。本申请实施例中，第一设备在连续5个PO之前确定的5个资源的5个资源索引值分别为：0，1，0，1，0。
再举例来说，第一设备根据所述第一预设规则，从第二PO之前的同一间隙对应的至少两个预设资源中确定第二资源；所述第二资源在所述第二PO之前的同一间隙对应的至少两个预设资源中的资源索引值，与所述第一资源在所述第一PO之前的同一间隙对应的至少两个预设资源中的资源索引值不相同。
通过这种方法，能够保证第一设备不会每次都在一个预设资源中监听唤醒信号序列，从而降低第一设备接收到不希望接收的唤醒信号序列的概率。
每个PO之前确定的资源的资源索引值可以不同，也可以相同。例如，第一设备在PO1之前确定出的资源的资源索引值为0，在PO2之前确定出的资源的资源索引值为2。
本申请实施例中，第一预设规则可以存在多种实现方式，下面分别进行描述。
第一种可能的实现方式中，所述第一预设规则包括：
根据来自第二设备的第一指示信息确定监听唤醒信号序列的资源。第二设备为发送唤醒信号序列的设备。
此时，第一设备可以将所述至少两个预设资源中所述第一指示信息指示的资源作为所述第一资源。
例如，第一指示信息指示在PO1之前，在距离PO1最近的预设资源中监听唤醒信号序列，在PO2之前，在距离PO2最远的预设资源中监听唤醒信号序列。第一设备按照第一指示信息的指示，在相应的预设资源中监听唤醒信号序列即可。
通过这种方法，根据第一指示信息，可以保证第一设备需要监听的唤醒信号序列，能够被监听到，从而提高第一设备接收唤醒信号序列的成功率。
第二种可能的实现方式中，所述第一预设规则包括：
根据所述第一设备的标识、所述第一PO所在的系统帧号、所述第一PO所在的超帧号以及所述第一设备的非连续接收周期中的至少一项确定资源索引值。
如前所述，本申请实施例中，每个PO之前的同一间隙对应的至少两个预设资源中的每个预设资源与一个资源索引值对应，因此第一设备可以将第一PO之前的同一间隙对应的至少两个预设资源中，与所述资源索引值对应的预设资源作为监听唤醒信号序列的资源，即第一资源。
需要说明的是，针对第二PO可以采用同样的方法确定资源索引值，在此不再赘述。
举例来说，结合图2，预设资源1的资源索引值为0，预设资源2的资源索引值为1。
第一设备根据第一预设规则确定的资源索引值为0时，在预设资源1中监听唤醒信号序列，相应的，确定的资源索引值为1时，在预设资源2中监听唤醒信号序列。
具体如何确定资源索引值，可能存在多种场景，举例来说，所述资源索引值满足以下任一公式：
Figure PCTCN2019085379-appb-000013
Figure PCTCN2019085379-appb-000014
其中，Val表示所述资源索引值，UE_ID表示所述第一设备的标识，f(UE_ID)为所述UE_ID的函数，SFN表示所述第一PO所在的系统帧号(system frame number，SFN)，HFN表示所述第一PO所在的超帧号(hyper system frame number，HSFN)，T location表示预设变换周期，DRX_cycle表示所述第一设备的非连续接收周期，N表示每个PO之前的同一间隙对应的预设资源的数量，mod表示取余运算，
Figure PCTCN2019085379-appb-000015
表示向下取整运算。其中，1个超帧包括1024个系统帧。需要说明的是，f(UE_ID)是对UE_ID进行运算后获得的值，例如可以对UE_ID进行取模运算，例如f(UE_ID)＝UE_ID mod X，X为预设取值，或者该函数就是UE_ID本身，即f(UE_ID)＝UE_ID。
举例来说，结合图2，预设资源1的资源索引值为0，预设资源2的资源索引值为1。假设f(UE_ID)＝0、DRX_cycle＝128、T location＝2，在不同系统帧中的PO之前，确定的资源索引值可以如表1所示。
表1
PO所在的系统帧号 资源索引值
32 0
32+128＝160 0
32+128＊2＝288 1
32+128＊3＝416 1
32+128＊4＝544 0
32+128＊5＝672 0
需要说明的是，以上只是示例，还可能存在多种上述公式的变形，在此不再逐一举例说明。
第三种可能的实现方式中，所述第一预设规则包括：
将PO之前的同一间隙对应的至少两个预设资源中，与所述第一设备所处的组的组标识对应的预设资源作为监听唤醒信号序列的资源。
本申请实施例中，可以将多个设备分为一个组(group)，每一组中的所有设备通过组标识进行区分。因此，可以预先规定，在PO之前的同一间隙对应的每个预设资源，与至少一个组标识存在映射关系。在该情况下，第一设备可以在第一设备所处的组的组标识对应的预设资源中，监听唤醒信号序列。
举例来说，结合图2，假如包括6个组，组标识分别为0～5。组标识为0、1、2、3的4个组中的设备监听预设资源1，组标识为4、5的2个组中的设备监听预设资源2。当第一设备确定其所处的组的组标识为2时，在预设资源1中监听唤醒信号序列；当第一设备确定其所处的组的组标识为5时，在预设资源2中监听唤醒信号序列，其它情况不在赘述。
示例性的，PO之前的每个预设资源对应的组的数量由第二设备配置。需要说明的是，每个预设资源对应的组的数量可以相同，也可以不同，本申请实施例对此并不限定。
举例来说，结合图2，第二设备可以向第一设备发送N1、N2，N1表示预设资源1中对应的组的数量，N2表示预设资源2中对应的组的数量。N1、N2为大于或等于0的整数。
再举例来说，第二设备可以向第一设备发送N、N1。N1表示预设资源1中对应的组的数量，N表示预设资源2中对应的组的数量与预设资源1中对应的组的数量的总和。第一设备可以确定预设资源2中对应的组的数量N2＝N-N1。
需要说明的是，本申请实施例中，第一预设规则还可以存在其他实现方式，只要第一预设规能够实现在不同PO之前确定的资源的资源索引值不同或相同，或者，在连续K个PO之前确定的K个资源的K个资源索引值中存在不相同的资源索引值即可，在此不再逐一举例说明。
如前所述，目前可以将多个设备分为一个组，每一个组通过组标识进行区分。通过将设备划分为多个组，可以为每组设备分配至少一个唤醒信号序列，该组中的设备在监听到该组对应的任一唤醒信号序列时，在PO位置醒来；相应的，该组中的设备在监听到其它组对应的唤醒信号序列时，可以在PO位置保持睡眠状态。
举例来说，假如有6组设备，这6组设备与唤醒信号序列的对应关系可以如表2所示。
表2
Figure PCTCN2019085379-appb-000016
Figure PCTCN2019085379-appb-000017
表2中，唤醒信号序列的序列索引值，用于标识一个唤醒信号序列。当第一设备所处的组的组标识为1时，需要监听序列索引值分别为#1、#2以及#8的唤醒信号序列；当第一设备所处的组的组标识为5时，需要监听序列索引值分别为#0、#6以及#9的唤醒信号序列，其它情况不再赘述。
通过上面的描述可知，不同分组之间的组合情况非常多，由于终端设备的分组可能是经常变化的，因此终端设备需要监听的唤醒信号序列也可能经常变化，因此终端设备如何确定需要监听的唤醒信号序列，是一个亟待解决的问题。
为此本申请实施例中，提供一种通信方法，在增加信令开销的情况下，终端设备可以实时确定出需要监听的唤醒信号序列，下面将详细描述。
结合前面的描述，如图5所示，为本申请实施例提供的一种通信方法流程示意图。图5中，第一设备可以为终端设备，第二设备可以为网络设备，在本申请实施例中，第一设备和第二设备也可以均为终端设备。进一步的，第一设备可以为支持NB-IoT R15或NB-IoT R16的终端设备。参见图5，该方法包括：
步骤501：第二设备根据第二预设规则确定至少一个第一唤醒信号序列；
步骤502：第二设备在第一寻呼机会PO之前的第一预设资源中发送所述至少一个第一唤醒信号序列中的一个第一唤醒信号序列。
步骤503：第一设备根据第二预设规则确定在第一寻呼机会PO之前的第一预设资源中监听的至少一个第一唤醒信号序列；
步骤504：第一设备在所述第一预设资源中监听所述至少一个第一唤醒信号序列。
需要说明的是，步骤502以及步骤504中，第一预设资源可以为根据第一预设规则确定的，具体如何确定，可以参考图4所示的流程中的描述，在此不再赘述。
其中，至少一个第一唤醒信号序列的数量为L，L的取值并不限定，例如可以为3或4。L的取值可以为第二设备配置的，也可以通过其他方式约定，在此不再赘述。
通过上述方法，第一设备通过第二预设规则，可以确定出需要监听的至少一个唤醒信号序列。由于第二预设规则是预先定义的，因此即使第一设备所处的分组发生变化，也能够确定出需要监听的至少一个唤醒信号序列。同时，这种方法不需要第二设备主动通知第一设备，从而避免了额外的信令开销，提高了系统效率。
本申请实施例中，根据第二预设规则在不同PO之前确定出的唤醒信号序列的数量不 同或相同，和/或，根据所述第二预设规则在不同PO之前确定出的至少一个唤醒信号序列的生成参数集合不同，所述生成参数集合中包括至少一个生成参数，每个生成参数能够用于生成一个唤醒信号序列，每个生成参数根据所述第一设备所处的组的组标识确定。
举例来说，第一设备还可以根据所述第二预设规则，确定在第二PO之前的第二预设资源中监听的至少一个第二唤醒信号序列。
其中，所述至少一个第二唤醒信号序列的数量与所述至少一个第一唤醒信号序列的数量不同，和/或，所述至少一个第二唤醒信号序列的生成参数集合与所述至少一个第一唤醒信号序列的生成参数集合不同。所述生成参数集合中包括至少一个生成参数，每个生成参数用于生成一个唤醒信号序列，每个生成参数根据所述第一设备所处的组的组标识确定。
本申请实施例中，所述第二预设规则可以包括：
根据所述第一设备的标识、第一PO所在的系统帧号、所述第一PO所在的超帧号以及所述第一设备的非连续接收周期中的至少一项确定第一标识。
在第一标识对应的预设映射表中，将与所述第一设备所处的组的组标识对应的唤醒信号序列作为在所述第一PO之前监听的唤醒信号序列，所述预设映射表中包括至少一对映射关系，每对映射关系为一个唤醒信号序列的序列索引值或生成参数与至少一个组标识的映射关系，每个组标识对应一组设备。
举例来说，假如有6组设备，组标识分别为1至6，这6组设备与唤醒信号序列的对应关系可以如表3、表4以及表5所示。

Figure PCTCN2019085379-appb-000020
表5
Figure PCTCN2019085379-appb-000021
第一设备所处的组的组标识为2，当确定出的第一标识为0时，第一设备需要监听的唤醒信号序列的索引值分别为#1、#3以及#8。当确定出的第一标识为2时，第一设备需要监听的唤醒信号序列的索引值分别为#1以及#2，其它情况不在赘述。
需要说明的是，针对第二PO可以采用同样的方法确定第一标识，在此不再赘述。
具体如何确定第一标识，可能存在多种场景，举例来说，所述第一标识满足以下任一公式：
Figure PCTCN2019085379-appb-000022
Figure PCTCN2019085379-appb-000023
其中，Set_ID表示所述第一标识，UE_ID表示所述第一设备的标识，f(UE_ID)为所述UE_ID的函数，SFN表示所述第一PO的系统帧号，HFN表示所述第一PO的超帧号，DRX_cycle表示所述第一设备的非连续接收周期，M表示所述第一预设资源对应的预设映射表的总数量，mod表示取余运算，
Figure PCTCN2019085379-appb-000024
表示向下取整运算，所述预设映射表中包括至少一对映射关系，每对映射关系为一个唤醒信号序列的序列索引值与至少一个组标识的映射关系，每个组标识对应一组设备。需要说明的是，f(UE_ID)是对UE_ID进行运算后获得的值，例如可以对UE_ID进行取模运算，例如f(UE_ID)＝UE_ID mod X，X为预设取值，或者该函数就是UE_ID本身，即f(UE_ID)＝UE_ID。
需要说明的是，所述M的具体取值为可以为第二设备配置的。第二设备配置M后，将M发生至第一设备。
举例来说，结合表1至表3，假设f(UE_ID)＝0、DRX_cycle＝128、M＝3，随着SFN的不断增加，根据公式(3)确定出的第一标识可以为0、1、2、0、1、2、…等等。
需要说明的是，本申请实施例中，第二预设规则还可以存在其他实现方式，在此不再逐一举例说明。
进一步可选的，本申请实施例中，每个预设映射表中，每组设备对应的唤醒信号序列的数量相同。例如，如表3所示，每组设备均对应3个唤醒信号序列。
通过这种方法，使得每组设备需要监听的唤醒信号序列的数量相同，保证每组设备之间获得相同的监听机会。
当网络设备只配置了1个预设资源，该预设资源为Group WUS resource，即用来发送组唤醒信号序列时，该预设资源有两种可能位置，位置1：与NB-IoT R15中定义的legacy WUS resource重合，即图2中的预设资源2；位置2：位于NB-IoT R15中定义的legacy WUS resource前面的资源，即NB-IoT R16中新定义的资源，图2中的预设资源1。
此时，终端设备在哪个预设资源中监听唤醒信号序列是一个亟待解决的问题。
一种可能的实现方式中，网络设备向终端设备发送第二指示信息，第二指示信息用于指示监听唤醒信号序列的资源。终端设备接收到第二指示信息之后，可以将PO之前的同一间隙对应的两个预设资源中，所述第一指示信息指示的资源作为监听唤醒信号序列的资源。
另一种可能的实现方式中，当终端设备的唤醒信号序列最大持续时长(WUS maximum duration)大于或等于预设阈值时，终端设备将PO之前的同一间隙对应的两个预设资源中，资源一作为监听唤醒信号序列的资源；当终端设备的唤醒信号序列最大持续时长(WUS maximum duration)小于预设阈值时，终端设备将PO之前的同一间隙对应的两个预设资源中，资源二作为监听唤醒信号序列的资源。资源一为同一间隙的两个预设资源中，与起始位置与PO的起始位置距离较近的预设资源；资源二为同一间隙的两个预设资源中，与起始位置与PO的起始位置距离较远的预设资源。
以上只是示例，还可以根据唤醒信号序列最大持续时长、nB中的至少一项确定监听唤醒信号序列的资源。其中nB表示寻呼密度，即一个DRX周期内PO的个数，取值范围是{4T，2T，T，T/2，T/4，T/8，T/16，T/32，T/64，T/128，T/256，T/512，T/1024}，T为预设周期。
