配置信息指示方法及通信装置
本申请要求于2018年04月04日提交中国国家知识产权局、申请号为201810301975.6、申请名称为“一种指示低功耗设备通信资源的方法、设备及系统”的中国专利申请的优先权，以及于2018年06月22日提交中国国家知识产权局、申请号为201810654254.3、申请名称为“配置信息指示方法及通信装置”的中国专利申请的优先权，它们的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，尤其涉及配置信息指示方法及通信装置。
背景技术
对于配置有唤醒射频/唤醒接收机(wake-up radio/wake-up receiver，WUR)模块的用户设备(user equipment，UE)来说，当基站没有数据向UE发送且UE也没有数据传输时，UE的主通信接口处于关闭状态，而WUR接口处于激活状态或间歇性激活状态。当基站有数据向UE发送时，首先向UE的WUR接口发送唤醒信号，以便使UE唤醒自己的主通信接口。UE唤醒自己的主通信接口之后，根据自身处于无线资源控制(radio resource control，RRC)连接态还是RRC空闲态，选择不同的流程接入网络。
在第五代(5th-generation，5G)新无线(new radio，NR)网络中，UE需要获取网络的带宽部分(bandwidth part，BWP)配置信息，才能知道在哪个信道接入网络。如果UE从WUR激活状态唤醒主通信接口前处于RRC连接态，则需要在网络所指示的BWP上发起随机接入流程，随后接入网络进行相应的数据交互；如果UE从WUR激活状态唤醒主通信接口前处于RRC空闲态，则可能需要经过小区搜索过程、随机接入过程才能接入网络。
由于UE从关闭主通信接口，进入WUR激活状态后，再到唤醒主通信接口的这个过程中，所在小区的BWP配置可能发生了变化。无论UE是处于RRC连接态还是RRC空闲态，小区BWP配置的变化都可能引起UE无法成功接入网络的问题，UE必须重新经历一次小区搜索和随机接入的流程，这会带来一定的时延问题。
发明内容
本申请实施例提供了配置信息指示方法及通信装置，用于减少通信时延。
有鉴于此，本申请第一方面提供了一种配置信息指示方法，该方法包括：终端设备接收网络设备发送的唤醒信号，该唤醒信号包括BWP指示信息，则终端设备根据该BWP指示信息确定目标BWP，并使用目标BWP与网络设备进行通信。

本实现方式提供了另一种指示目标BWP的方式，提高了方案的灵活性。
本申请第二方面提供了一种配置信息指示方法，该方法包括：当网络设备确定需要唤醒终端设备的主通信接口时，网络设备确定终端设备在主通信接口唤醒后对应的第一BWP配置，然后向终端设备发送唤醒信号，该唤醒信号用于唤醒主通信接口，并且该唤醒信号包括BWP指示信息，终端设备根据该BWP指示信息可以确定与网络设备进行通信的目标BWP，该目标BWP为第一BWP配置中的BWP。
本实现方式中，当网络设备需要唤醒终端设备的主通信接口是，即网络设备有数据需要向终端设备发送时，会向终端设备发送唤醒信号，并且该唤醒信号携带有BWP指示信息，终端设备接收到该唤醒信号后，可以根据该唤醒信号中的BWP指示信息确定目标BWP，并使用该目标BWP与网络设备进行通信。即本申请中可以将终端设备在唤醒后要使用的BWP对应的指示信息携带在唤醒信号中，终端设备在唤醒主通信接口后，不需要进行小区搜索和随机接入，直接根据唤醒信号中的指示信息就可以知道在唤醒后要使用那一段BWP进行通信，减少了终端设备的通信时延。

本实现方式提供了一种指示目标BWP的方式，提高了方案的灵活性。
在一种可能的实现方式中，网络设备向终端设备发送唤醒信号之前可以执行如下流程：网络设备判断第一BWP配置对应的网络配置状态相对于第二BWP配置对应的网络配置状态是否发生了变化，若发生了变化，则网络设备判断第一BWP配置中的初始态BWP与第二BWP配置中的初始态BWP是否相同，若不相同，则网络设备确定第一BWP配置中的初始态BWP为目标BWP，即BWP指示信息包括如下至少一项：第一BWP配置中初始态BWP对应的BWP索引标识，第一BWP配置中初始态BWP的配置信息，第一BWP配置对应的全局BWP配置索引标识；若相同，则网络设备确定第二BWP配置中的初始态BWP为目标BWP，则BWP指示信息包括如下至少一项：初始态BWP对应的BWP类型指示，第二BWP配置中初始态BWP对应的BWP索引指示。
需要说明的是，本实现方式中，第二BWP配置指的是网络设备进入休眠状态前对应的BWP配置；网络配置状态具体包括：BWP划分信息和/或哥哥BWP对应的系统参数集信息。
本实现方式中，网络设备向终端设备指示目标BWP之前，如果网络配置状态没有发生变化，网络设备会判断初始态BWP是否发生变化，如果没有发生变化，则使用原来的初始态BWP进行通信，即使用终端设备已获取BWP配置(第二BWP配置)中的BWP进行通信，可以减少信令资源。
在一种可能的实现方式中，当网络设备确定第一BWP配置对应的网络配置状态相对于第二BWP配置对应的网络配置状态没有发生变化时，网络设备进一步判断第一BWP配置中的默认态BWP与第二BWP配置中的默认态BWP是否相同，若相同，则网络设备确定第二配置中的默认态BWP为目标BWP，即BWP指示信息包括如下至少一项：默认态BWP对应的BWP类型指示，或第二BWP配置中默认态BWP对应的索引标识。
本实现方式中，网络设备向终端设备指示目标BWP之前，如果网络配置状态没有发生变化，但是默认态BWP没有发生变化，则使用原来的默认态BWP进行通信，即使用终端设备已获取BWP配置(第二BWP配置)中的BWP进行通信，可以减少信令资源。

应理解，本申请实施例的技术方案可以应用于多种通信系统，例如：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、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)通信系统或第五代移动通信技术(5th-generation，5G)等，需要说明的是，本申请实施例并不限定具体的通信系统。

应理解，本申请实施例中的终端设备包括但不限于移动台(mobile station，MS)、用户设备(user equipment，UE)、移动终端(mobile terminal)、移动电话(mobile telephone)、手机(handset)及便携设备(portable equipment)等，该终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
为了便于理解，下面对本申请涉及的一些词汇进行介绍。
唤醒射频(wake-up radio，WUR)模块：唤醒射频又称为唤醒接收机(wake-up receiver，WUR)，为了便于描述，本申请实施例统一用唤醒射频来称呼。WUR模块指的是用于设备唤醒的模块，又称为WUR模块或WUR接口。
主通信接口(main radio)：用于数据通信的模块，又可以称为主模块，主接口或者主通信模块，如LTE接口、NR接口、无线保真(wireless-fldelity，Wi-Fi)接口、蓝牙接口(bluetooth)等。
唤醒信号(wakeup signal，WS)：可被唤醒射频接收并解码的信号，如唤醒帧、同步帧、唤醒包等。
带宽部分(Bandwidth Part，BWP)：对一个小区的高频频段进行划分得到多个字带宽，每个子带宽包含一定的系统参数集(numerology)特性。具体地，带宽部分可以分为初始态带宽部分(initial BWP)，默认态带宽部分(default BWP)和激活态带宽部分(active BWP)三个类型。其中，初始态BWP用于初始上行接入或下行接入的带宽部分；激活态BWP指的是处于激活状态的大带宽部分，用于高速数据传输；默认态BWP用于缺省配置，UE在激活态BWP去激活后，回退到默认态BWP中进行业务。默认态BWP在没有配置的时候，可以等于初始态BWP。默认态BWP有配置时，可以初始态BWP，也可以是除去初始态/激活态BWP后剩下的BWP。
为了便于理解本申请实施例，下面先对本申请中配置信息方法所适用的系统架构进行介绍，如图1所示，该系统包括基站101以及UE 102，其中，基站能够发送唤醒信号(如唤醒帧、同步帧等)给UE 102；UE 102配置了WUR模块和主模块，通过WUR模块UE 102可以接收基站101发送的唤醒信号，并根据唤醒信 号唤醒主模块。
UE配置WUR模块是实际上就是UE在配置传统主接口(主模块)的基础上，引入一个WUR接口(WUR模块)。主模块通常处于关闭状态，只有当收到来自WUR模块的触发信号时，主模块才会激活，然后通过主模块与基站进行数据通信。其中，触发信号可是由WUR模块发送给主模块的中断信号，用于触发主模块进入激活状态，触发信号是UE的内部信号，可通过有线或无线方式传输。需要说明的是，上述WUR模块发送触发信号给主模块是逻辑上的，在实际系统中，WUR模块也可以将收到的唤醒信号转发给处理器，由处理器决定是否唤醒主模块，此时，触发信号实际上是由处理器发出的，或由处理器指示其它模块发出的。
UE的WUR模块可以持续处于接收状态，也可以间歇性处于接收状态，具体本申请不作限定。具体地，UE的WUR模块持续处于接收状态，即UE的WUR始终处于监听状态，这样基站可以随时唤醒UE，可以有效降低唤醒延迟，但是这会使得UE的能耗升高。UE的WUR模块间歇性的处于接收状态，即UE的WUR模块间歇性处于激活状态，本申请中将WUR模块处于激活状态的时间窗称为唤醒窗口(wakeup window)，这些唤醒窗口的出现一般是规律性的，这样基站可以知道UE的WUR何时能够接收唤醒信号，例如，WUR在每100ms中有2ms处于激活状态，如图2所示。当基站有数据需要向UE发送时，可在该UE的唤醒窗口中发送唤醒信号，从而唤醒UE的主通信模块。唤醒窗口的起始时刻、窗口时长以及周期，可以是标准预定义的，也可以是基站配置的。
需要说明的是，基站在逻辑上也包括主模块和WUR模块，但对于当前第三代合作伙伴项目(the 3rd generation partnership project，3GPP)标准而言，主模块常常为正交频分复用(orthogonal frequency division multiplexing，OFDM)宽带发射机，而WUR的唤醒信号则可能是窄带信号(以降低WUR的接收功耗)，出于降低成本和结构简单考虑，可以利用OFDM宽带发射机产生窄带WUR唤醒信号。例如，将OFDM信号的部分子载波空置而仅在WUR唤醒信号对应的窄带上传输信号，从而产生窄带信号，这就是利用OFDM宽带发射机产生WUR窄带信号的例子，故图1中基站仅包含一个模块。需要特别说明的是，基站具体实现中也可将主模块和WUR模块分别进行单独实现，即图1基站侧也可以同时包含主模块和WUR模块。另外，图1中基站和UE都只有一个天线，这主要是考虑主模块和WUR模块使用相同或接近的频段载波情况下，可共用同一天线，以节省成本和简化设备结构。当然，主模块和WUR模块分别使用不同天线显然也是可行的。当主模块和WUR模块使用频域上距离较大的不同频段载波时，两者应配置不同天线。例如，主模块使用6GHz频段，WUR模块使用1.8GHz频段，此时两者应使用不同天线。
唤醒信号通常采用易于接收端解调的调制方式，例如开关键控(on-off key，OOK)调制、频移键控(frequency-shift keying，FSK)、振幅键控(amplitude shift keying，ASK)等。以OOK调制为例，接收端通过有无能量判断接收信号承载的信息，例如，有能量为1，无能量为0。而传统主接口信号(如LTE/NR的信号)由于在发送端采用OFDM 调制、涡轮码(turbo code)/低密度奇偶校验码(low density parity check code，LDPC)/极化码(polar code)信道编码等，相应地，接收端需执行离散傅氏变换的快速算法(fast fourier transformation，FFT)、前向纠错(forward error correction，FEC)译码等复杂信号处理操作，这些操作需要耗费大量能量。因此，UE采用WUR接收信号相比使用主模块接收信号能够降低功耗。另外，在一些方案中，出于节省成本和简化设计的考虑，UE的WUR接口往往只支持唤醒信号的接收能力即可，而无需支持发送能力。而本申请实施例中UE的WUR接口可以支持信号发送，也可以不支持信号发送，具体不作限定。
需要特别说明的是，本申请实施例中唤醒信号的发送端可以是基站，接收端是配备WUR的终端设备，如手机、传感器等；唤醒信号的发送端也可以是终端设备，如手机，接收端是配备WUR的其它终端设备，如智能手表、手环等；唤醒信号的发送端还可以是终端设备，如手机，接收端是配备WUR的基站。总之，唤醒信号的发送端需具备唤醒信号发送能力，接收端必须配备WUR接口以便接收唤醒信号。为便于描述，本申请中基站表示唤醒信号的发送端，UE表示唤醒信号的接收端，而不代表收发设备的具体产品形态。
在一些方案中，终端设备获取BWP配置的方式如图3所示。终端设备处于无线资源控制(radio resource control，RRC)空闲状态时，需要完成小区搜索和随机接入两个流程后完成网络的接入，具体地，小区搜索过程先行主同步/辅同步信号的检索，然后通过解码物理广播信道(physical broadcast channel，PBCH)获取当前最重要的系统消息，其中包括了用于上行接入的初始态BWP(initial uplink BWP)(可能也用于下行接入的初始态BWP(initial downlink BWP)的配置)。随后，UE发起随机接入过程，进入RRC连接态之后，获取完整的BWP配置。终端设备获取完整的BWP配置之后，在系统没有显性指令通知的时候，终端设备会认为当前的BWP配置没有发生变化，如果BWP配置发生了变化，则根据BWP配置变化的具体情况，会引发不同的处理流程，一般来说，这些处理流程是由网络侧指示UE完成的，即由网络侧向UE发送相关控制信令，UE根据相关控制信令执行相应流程。
但是，WUR模块的引入会带来WUR模块唤醒主通信接口的时延，并且该时延并不是固定的，这会使得UE所接收的相关控制信令时效性受到影响。WUR模块唤醒时延的影响对于超高可靠超低时延通信(ultra reliable&low latency communication,URLLC)等低时延要求高的场景来说，是不可忽视的因素，如果希望在这些应用场景中也使用WUR技术，就需要尽可能缩短WUR模块所产生的时延以满足场景需求。因此，本申请实施例提供了配置信息指示方法及通信装置，可以减少了终端设备与基站之间的通信时延。下面先对本申请中的配置信息指示方法进行介绍，请参阅图4，本申请实施例中配置信息指示方法的一个实施例包括：
401、网络设备确定终端设备在主通信接口唤醒后对应的第一BWP配置。
配置有WUR模块的终端设备进入休眠状态(即住通信接口)后，当网络设备确定需要唤醒终端设备的主通信接口时，网络设备确定终端设备在主通信接口唤 醒后对应的BWP配置。为了便于描述，本实施例将终端设备在唤醒后对应的BWP配置称为第一BWP配置，将终端设备进入休眠状态时对应的BWP配置称为第二BWP配置。
402、网络设备向终端设备发送唤醒信号。
网络设备确定第一BWP配置后，会从第一BWP配置中选择一段或者多段BWP，并通过BWP指示信息指示终端设备使用该BWP(目标BWP)进行通信，其中，该BWP指示信息携带在唤醒信号中，即本实施例中，网络设备确定第一BWP配置后，会向终端设备发送包含BWP指示信息的唤醒信号，以指示终端设备唤醒主通信接口，并使用目标BWP与网络设备进行通信。
需要说明的是，本实施例中，网络设备通过指示信息所指示的BWP(即目标BWP)可以是上行BWP(uplink bandwidth part，UL BWP)，可以是下行BWP(downlink bandwidth part，DL BWP)，还可以是下行BWP和上行BWP对(DL/UL BWP pair)，具体本申请不作限定。
本实施例中，网络设备可以通过如下至少一项信息指示终端设备使用哪一段BWP或者哪几段BWP进行通信(即BWP指示信息包括如下至少一项)：BWP索引标识，全局BWP配置索引标识，BWP配置信息，BWP类型的指示信息。
其中，BWP索引标识用于标识某个小区对应的BWP配置中的一段或多段BWP，具体可以包括BWP的索引号，或者与BWP的索引号具有映射关系的标识，或者其他可以标识BWP的信息，具体此处不作限定。

其次，本申请实施例中网络设备可以通过多种方式向终端设备指示目标BWP，终端设备可以通过多种方式确定目标BWP，提高了方案的灵活性。
为了便于理解，下面以具体的应用场景对本申请实施例中的配置信息指示方法进行介绍。
场景一、UE处于RRC连接状态，基站用BWP索引标识向UE指示BWP。
对于RRC连接态的UE，BWP配置是半静态的，基站用WUS唤醒UE时，若已配置的BWP没有发生变化，则可以在WUS中专门的BWP指示域指示UE唤醒主接口后，用BWP配置中的一段BWP来通信，具体流程如图6所示。
RRC连接态UE经过网络侧半静态的BWP配置后，当WUR模块处于接收状态时，UE通过该WUR模块接收基站发送的WUS，通过该WUS唤醒主通信接口，并使用基站在WUS所指示的BWP进行通信。
如图7所示，一个小区可以配置的BWP子带划分最多有4个，基站在WUS的BWP指示域中可以具体携带该小区BWP配置的BWP索引0,1,2,3中的一个或多个(BWP-index)以指示UE唤醒主通信接口之后进行通信所用的BWP，如图8所示。在非对称频谱中，该BWP索引可以是指示了一个上行BWP和一个下行BWP的配对索引。在对称频谱中，上下行BWP的索引还可以具体的用上行BWP索引(UL-BWP-index)和下行BWP索引(DL-BWP-index)指示。需要说明的是，小区级别的BWP配置可以是小区内统一的，也可以对每个UE唯一的。
场景二、不管RRC处于连接态或RRC处于空闲态，基站用全局BWP配置索引标识指示BWP配置。
无论UE处于RRC连接态还是RRC空闲态，网络侧都可以使用全局BWP配置 索引标识为UE指示唤醒主通信接口之后使用的BWP配置。如图9所示，网络中所有小区的BWP配置(及其参数)的种类是一个有限集，则每个小区唤醒WUR处于激活态的UE时，发送的WUS中可以具体携带一个全局BWP配置索引(global BWP configuration index，GBCI)以向UE指示唤醒主通信接口之后使用的BWP配置，WUS中还可以携带该BWP配置下的一个或多个BWP索引标识以指示UE唤醒主通信接口之后进行通信所用的BWP，流程如图10所示。需要说明的是，对于支持载波聚合技术的UE，WUS中还可以携带多个全局BWP配置索引。
应理解，本实施例中，网络侧除了可以使用全局BWP配置索引标识指示BWP配置，还可以在WUS中携带完整的BWP详细配置信息，其中包括BWP配置中每个BWP子带的系统集参数(Numerology)、带宽(bandwidth)、频域位置(frequency location)等等。但这种方法所需要的比特(bit)数多，为了减少信令资源，网络侧也可以使用初始态BWP的详细配置信息指示UE，或者使用默认态BWP的详细配置信息指示UE。
实施例三、不管RRC处于连接态或RRC处于空闲态，基站用与小区识别码(cell identification，cell ID)向UE指示BWP配置。
网络侧可以在WUS中携带cell ID，通过cell ID向UE指示BWP配置，cell ID与GBCI的映射关系如图11所示。UE根据WUS唤醒主通信接口后，使用WUS中的cell ID域，结合与预配置或者网络控制的映射关系确定唤醒主通信接口后可以使用的BWP(即确定唤醒后UE对应的BWP配置)，然后以所指示的BWP配置中的初始BWP与网络设备进行通信。
