技术领域
本申请涉及通信领域，并且更具体地，涉及一种信息指示的方法和通信装置。
背景技术
低能力(reduced capability)终端设备(user equipment，UE)是指对服务速率和时延没有那么高的要求，反而需要控制成本的终端设备，即低能力终端设备不需要有很强的硬件能力，与普通终端设备(legacy UE)相比较，接收天线数、工作带宽、处理时间等都会有所下降。
低能力终端设备按接收天线数量可分为有1根接收天线的终端设备(本申请中简称为1R UE)和有2根接收天线的终端设备(本申请中简称为2R UE)，1R UE因为接收天线数量少，所以覆盖要比2R UE和4R UE的UE差，这里的4R UE表示有4根接收天线的普通终端设备。如图1所示，基站服务的小区#1的覆盖范围为外侧较大的实线圆圈，4R UE覆盖范围(即可正常传输数据的范围)为内侧较大的虚线圆圈，1R UE覆盖范围为内侧较小的实线圆圈。所以如果想要让1R UE在内侧实线圈外且虚线圈内与4R UE一样能正常接收数据，基站就需要对1R UE做覆盖增强。
在一种技术中，基站可以通过系统信息块(system information block，SIB)1指示1R UE是否可以驻留小区#1。但该方法中，如果图1中的基站为不支持覆盖增强的基站，当基站指示1R UE都能够驻留小区#1时，这种情况下，如果部分1R UE位于图1的内侧实线圈外且虚线圈内，因为基站不支持覆盖增强会导致1R UE驻留之后无法正常接收数据；当基站指示1R UE都不能驻留小区#1时，这种情况下，如果部分1R UE位于图1的内侧实线圈内(即小区#1中心)，不需要基站对1R UE做覆盖增强，由于基站指示1R UE都不能驻留小区#1，那么基站也会禁止这部分1R UE驻留小区#1，即处于小区#1中心的1R UE也无法正常驻留到此小区上。
发明内容
本申请提供一种信息指示的方法和通信装置，以单个UE为粒度，UE通过RSRP阈值能够确定网络设备是否允许UE驻留或UE是否可以正常接收数据，能够节省UE的功耗和时间。
第一方面，提供了一种信息指示的方法，该信息指示的方法可以由终端设备执行，或者，也可以由设置于终端设备中的芯片或电路执行，本申请对此不作限定，为了便于描述，下面以由终端设备执行为例进行说明。该方法包括：终端设备从网络设备接收第一消息；终端设备根据第一消息中是否包括参考信号接收功率RSRP阈值确定是否被允许驻留第一小区。
上述技术方案中，相比图1中不支持覆盖增强的网络设备直接指示某一类型UE是否可以驻留第一小区，可能会导致本来能够驻留小区#1的UE却被指示无法驻留小区#1，或者，导致不能驻留小区#1的UE驻留小区后却无法正常接收数据，这样，无法驻留小区#1和无法正常接收数据的UE会继续选择新的小区进行驻留，浪费了UE的功耗和时间。而本申请提出的方案以单个UE为粒度，UE通过第一消息中的RSRP阈值能够准确判断自己是否能够驻留第一小区或是否可以正常接收数据，能够避免由于直接指示导致的部分UE再次进行小区选择的问题，节省了UE的功耗和时间。
结合第一方面，在第一方面的某些实现方式中，当第一消息中包括RSRP阈值时，终端设备的RSRP值小于RSRP阈值时，终端设备不被允许驻留第一小区，终端设备的RSRP值大于RSRP阈值时，终端设备被允许驻留第一小区，终端设备的RSRP值等于RSRP阈值时，终端设备被允许驻留第一小区，或者，终端设备不被允许驻留第一小区。

上述技术方案中，当UE进行小区切换(或小区重选)时，UE会根据第一指示信息仅读取相关的SIB消息，可以让UE在某些情况下少读一部分SIB消息，而不是将所有关于小区重选的SIB消息都读一遍，从而节省UE功耗和小区选择时间；当UE进行初始小区选择时，可以让UE读取相关的SIB消息，而不是所有的SIB消息都不读而进行小区盲选，从而减少了小区盲选次数，节省UE功耗和小区选择时间。

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：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)，车到其它设备(vehicle-to-X V2X)，其中V2X可以包括车到互联网(vehicle to network，V2N)、车到车(vehicle to-vehicle，V2V)、车到基础设施(vehicle to infrastructure，V2I)、车到行人(vehicle to pedestrian，V2P)等、车间通信长期演进技术(long term evolution-vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(internet of things，IoT)、机器间通信长期演进技术(long term evolution-machine，LTE-M)，机器到机器(machine to machine，M2M)等。
本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统等。本申请对此不做限定。
参见图2，图2是本申请实施例提供的一种网络架构的示意图。如图2所示，本申请实施例的通信系统可以包括网络设备和多个终端设备。网络设备可包括1个天线或多个天线。另外，网络设备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)。
网络设备可以与多个终端设备通信。本申请实施例中的终端设备也可以称为：用户设 备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、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等。
终端设备可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)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、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，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)中的终端设备和/或用于在无线通信系统上通信的任意其它适合设备，本申请实施例对此并不限定。
其中，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，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。
此外，在本申请实施例中，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LTE系统中的演进型基站B(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，还可以是无线网络控制器(radio network controller，RNC)、基站控制器(base station controller，BSC)、家庭基站(例如，home evolved nodeB，或home nodeB，HNB)、基带单元(baseband unit，BBU)，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，可以是无线局域网(wireless local area networks，WLAN)中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等,可以是新型无线系统(new radio，NR)系统中的gNB或传输点(TRP或TP)，或者， 5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
另外，在本申请实施例中，网络设备为小区提供服务，终端设备通过网络设备分配的传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于宏基站(例如，宏eNB或宏gNB等)，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，在本申请实施例中，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。
为了更好地理解本申请实施例，下面先介绍本申请实施例中涉及到的概念。
1、同步信号块(synchronization signal and PBCH block，SSB)：包含主/辅同步信号以及物理广播信道(physical broadcast channel，PBCH)，为UE提供小区下行同步，以及小区的基本配置信息，其中PBCH中会承载小区的主信息块(master information block,MIB)，MIB中会指示是否有SIB1存在，以及SIB1的位置。
2、小区禁止(Cellbarred)：小区禁止是网络控制负载的一种方式，当网络负载较重的时候，网络可以控制UE不要驻留在某个小区。针对普通(legacy)UE的小区驻留指示，即Cellbarred IE，是通过MIB消息广播给UE的，但是目前MIB中只剩下1比特(bit)可用，所以针对低能力UE的cellbarred IE可以携带在SIB1中去指示，这种方法可以让基站更加灵活的指示legacy UE和低能力UE是否被允许驻留小区。
应理解，当UE做初始小区选择时被禁止驻留时，此时UE不会读其他SIB消息(SIB2、3、4等)，但小区重选的参数包含于这些SIB消息中，所以UE不会读取小区重选的参数而进行小区盲选。
还应理解，当低能力UE成功驻留到某一服务小区，并要向目标小区进行切换时，因 为低能力UE已经成功驻留到该服务小区，所以可以读取其小区重选相关的SIB消息(如SIB2、3、4等)，此时UE可根据相关SIB消息中的参数来进行小区重选。
3、SIB2至SIB5包含的信息：
SIB2包含同频、异频和/或异系统小区重选相关的公共信息；
SIB3包含仅与同频小区重选相关的邻区相关信息，IE包括具有特定重选参数的小区和黑名单小区；
SIB4包含仅与异频小区重选相关的信息，即与小区重选相关的其他NR频率和异频邻区的信息。
SIB5包含仅与系统间小区重选相关的信息，即与小区重选相关的演进的通用陆面无线接入(evolved universal terrestrial radio access，E-UTRA)频率和E-UTRA相邻小区的信息。
下面对本申请提出的信息指示的方法进行详细描述。
参见图3，图3是本申请提出的一种信息指示的方法的示意性流程图。
S301，网络设备确定第一消息，第一消息通过是否包括参考信号接收功率(reference signal received power，RSRP)值指示接收到第一消息的UE是否被允许驻留第一小区。
当第一消息中包括RSRP阈值时，可以有以下两种表达方式：
(1)当第一消息中包括RSRP阈值时，如果UE的RSRP值小于RSRP阈值，UE不被允许驻留第一小区；如果UE的RSRP值大于RSRP阈值，UE被允许驻留第一小区；如果UE的RSRP值等于RSRP阈值，UE被允许驻留第一小区，或者，UE不被允许驻留第一小区。
(2)当第一消息中包括RSRP阈值时，无论UE的RSRP值为多少都被允许驻留第一小区。如果UE的RSRP值小于RSRP阈值，UE不能正常接收网络设备发送的数据；如果UE的RSRP值大于RSRP阈值时，UE能够正常接收网络设备发送的数据；如果UE的RSRP值等于RSRP阈值，UE不能正常接收网络设备发送的数据，或者，UE能够正常接收网络设备发送的数据。
当第一消息中不包括RSRP阈值时，可以表示UE不被允许驻留所述第一小区。
可选地，第一消息中还包括第一指示信息，第一指示信息用于指示第一类型终端设备是否被允许驻留第一小区。需要说明的，上述通过RSRP阈值判断是否能够驻留第一小区的UE可以理解为第二类型终端设备，其中，第一类型终端设备和第二类型终端设备为不同类型的终端设备。具体地，第一类型终端设备和第二类型终端设备为能力不同的终端设备。作为示例，该实施例中第一类型终端设备为2R UE，第二类型终端设备为1R UE。
可选地，当第一消息中不包括第一指示信息时，第一类型终端设备不被允许驻留第一小区。
可选地，第一消息为第一小区对应的SIB1消息。
在一种可能的具体实现方式中，网络设备可以在SIB1(即第一消息的一例)中为低能力UE添加一个新的cellbarred IE，例如Cellbarred-redcap indication(即第一指示信息的一例)，用来指示2R UE是否允许驻留，发送Cellbarred-redcap indication的同时再携带一RSRP阈值，用来指示1R UE是否允许驻留或是否可以正常接收数据。
可以看出，相比通过两个指示信息分别指示1R UE和2R UE是否被允许驻留的方法， 该实现方式中只使用了一个指示信息，即UE可以通过在一个指示信息中携带一个RSRP阈值指示1R UE和2R UE是否被允许驻留，从而节约了信令开销。
S302，网络设备发送第一消息。
可选地，网络设备向第一小区内的UE广播第一消息。
对应的，UE接收第一消息。
S303，UE根据第一消息中是否包括参考信号接收功率RSRP阈值确定是否被允许驻留第一小区。
关于UE是否被允许驻留第一小区参见S301中的描述，这里不再赘述。
可以看出，相比图1中不支持覆盖增强的网络设备直接指示某一类型UE是否可以驻留第一小区，可能会导致本来能够驻留小区#1的UE却被指示无法驻留小区#1，或者，导致不能驻留小区#1的UE驻留小区后却无法正常接收数据，这样，无法驻留小区#1和无法正常接收数据的UE会继续选择新的小区进行驻留，浪费了UE的功耗和时间。而本申请提出的方案以单个UE为粒度，UE通过第一消息中的RSRP阈值能够准确判断自己是否能够驻留第一小区或是否可以正常接收数据，能够避免由于直接指示导致的部分UE再次进行小区选择的问题，从而节省了UE的功耗和时间。同时，相比通过两个指示信息分别指示1R UE和2R UE是否被允许驻留的方法，节省了信令开销。
在一种实现中，当UE进行初始小区选择时，UE不被允许驻留第一小区，此时UE会进行小区盲选，重新选择其他小区进行驻留，如前所述，当UE做初始小区选择时被禁止驻留时，此时UE不会读其他SIB消息(SIB2、3、4等)，但小区重选的参数包含于这些SIB消息中，所以UE不会读取小区重选的参数而进行小区盲选。但UE可能会选到不支持UE驻留的小区上，浪费低能力UE的功耗和时间。
有鉴于此，本申请提出另一种信息指示的方法，能够减少UE小区盲选的次数，使低能力UE更快的找到合适的小区去驻留。
参见图4，图4是本申请提出的另一种信息指示的方法的示意性流程图。
S401，网络设备确定第一消息，第一消息包括第一指示信息，第一指示信息用于指示一个或多个支持或不支持第三类型终端设备驻留的第二小区，第二小区为第一小区的邻区。
可选地，第三类型终端设备可以为2R UE和/或1R UE。当第三类型终端设备为2R UE，可以理解为第一指示信息用于指示一个或多个支持或不支持2R UE驻留的第二小区；当第三类型终端设备为1R UE，可以理解为第一指示信息用于指示一个或多个支持或不支持1R UE驻留的第二小区；当第三类型终端设备为1R UE和2R UE，可以理解为第一指示信息用于指示一个或多个支持或不支持2R UE驻留的第二小区，同时第一指示信息还用于指示一个或多个支持或不支持1R UE驻留的第二小区。
可选地，当第三类型终端设备仅指示一个类型的终端设备，那么第一消息还可以包括第二指示信息，第二指示信息用于指示一个或多个支持或不支持第二类型终端设备驻留的第三小区，其中，第三小区为第一小区的邻区，第二类型终端设备和第三类型终端设备为不同类型的终端设备。作为示例，第三类型终端设备为2R UE，第二类型终端设备为1R UE。
可选地，第一消息为第一小区对应的SIB1消息。
在一种可能的具体实现方式中，网络设备可以在SIB1(即第一消息的一例)中添加支持或不支持低能力UE的邻区列表(即redcap-supported/redcap-unsupported list)(即第一指示信息的一例)。
可选地，上述支持或不支持低能力UE的邻区列表可以为所有支持或不支持低能力UE的邻区列表，也可以为部分支持或不支持低能力UE的邻区列表。
S402，网络设备发送第一消息。
可选地，网络设备向第一小区内的UE广播第一消息。
对应的，UE接收第一消息，其中，UE为第三类型终端设备。
S403，当UE在第一小区进行小区切换时或当UE被禁止驻留第一小区时，UE根据第一指示信息重新选择小区进行驻留。
上述技术方案中，既适用于初始小区选择的情况，也适用于小区切换的情况。这里主要说明适用于初始小区选择的情况，当UE进行初始小区选择被禁止驻留第一小区，UE可以基于网络设备配置在第一消息中的支持或不支持UE的邻区信息，不接收不支持UE的邻区的广播信息，或仅接收支持UE的邻区的广播信息，或同时根据支持和不支持UE的邻区信息来减少UE进行小区盲选的次数，让UE能够更快的找到合适的小区去驻留，从而节省UE功耗和小区选择时间。
在另一种实现中，如果UE当前已成功驻留到第一小区，并要向目标小区进行切换，当UE进行小区重选时，由于网络设备在小区重选相关的SIB消息(如SIB2、3、4等)里添加了支持UE的邻区列表，UE想要获取这些信息就需要把所有有关小区重选相关的SIB消息都读一遍以确定哪些邻区支持UE驻留，比较浪费UE的功耗和时间。
有鉴于此，本申请提出了又一种信息指示的方法，能够使UE更快地找到合适的小区去驻留。
参见图5，图5是本申请提出的又一种信息指示的方法的示意性流程图。
S501，网络设备确定第一消息，第一消息包括第一指示信息，第一指示信息用于指示UE在第一小区进行小区切换时或UE被禁止驻留第一小区时，读取第一小区对应的关于小区重选的SIB消息中的一个或多个消息，该一个或多个消息中包括支持UE的邻区信息。
可选地，如果第一小区对应的关于小区重选的SIB消息中存在支持UE的同频邻区，但不存在支持UE的异频邻区，则第一指示信息用于指示UE读取第一小区对应的包含支持UE的同频邻区信息的SIB消息。作为示例，第一指示信息指示UE仅读取SIB2和/或SIB3消息即可，而不用读取SIB4等其他不相关的涉及小区重选的SIB消息。可以理解，该示例中的第一指示信息也间接指示了第一小区的异频邻区都不支持UE驻留。
可选地，如果第一小区对应的所有关于小区重选的SIB消息中存在支持UE的异频邻区，但不存在支持UE的同频邻区，则第一指示信息用于指示UE读取第一小区对应的包含支持UE的异频邻区信息的SIB消息。作为示例，第一指示信息指示UE仅读取SIB2和/或SIB4消息即可，而不用读取SIB3等其他不相关的涉及小区重选的SIB消息。可以理解，该示例中的第一指示信息也间接指示了第一小区的同频邻区都不支持UE驻留。
可选地，第一消息为第一小区对应的SIB1消息。
在一种可能的具体实现方式中，网络设备可以在SIB1(即第一消息的一例)中为UE添加一个新的IE，Related-SI indication(即第一指示信息的一例)，当UE进行小区重选 时，UE会根据此IE读取相关必要的SIB消息，而不是将所有关于小区重选的SIB消息都读一遍。
可选地，第一消息中可以不包括第一指示信息，可以表示如下两种情况：
(1)表示第一小区对应的关于小区重选的SIB消息中存在支持UE的同频和异频邻区信息，UE按照现有流程正常读取第一小区对应的所有关于小区重选的SIB消息。
(2)表示第一小区对应的关于小区重选的SIB消息中不存在支持UE的邻区信息，UE无需读取第一小区对应的关于小区重选的SIB消息。
S502，网络设备发送第一消息。
示例性地，网络设备向第一小区内的UE广播第一消息。
对应的，UE接收第一消息。
S503，当UE在第一小区进行小区切换时或当UE被禁止驻留第一小区时，UE根据第一指示信息读取第一小区对应的关于小区重选的SIB消息中的一个或多个消息。
可选地，第一消息中可以不包括第一指示信息，UE如何读取关于小区重选的SIB消息参见S501中的描述，这里不再赘述。
可选地，该实施例中的UE可以为低能力终端设备，也可以为普通UE，本申请对此不做具体限定。
上述技术方案中，当UE进行小区切换(或小区重选)时，UE会根据第一指示信息仅读取相关的SIB消息，可以让UE在某些情况下少读一部分SIB消息，而不是将所有关于小区重选的SIB消息都读一遍，从而节省UE功耗和小区选择时间；当UE进行初始小区选择并被禁止驻留当前小区时，可以让UE读取相关的SIB消息，而不是所有的SIB消息都不读而进行小区盲选，从而减少了小区盲选次数，节省UE功耗和小区选择时间。
应理解，当网络设备广播这些SIB消息时，具有相同传输周期的SIBs可以映射到相同或不同的系统消息中，不同传输周期的SIBs不能映射到同一个系统消息中。所以当这些SIB消息传输周期不同时，SIB2、3、4、5可能会映射到不同的系统消息上，此时，上述方案可以实现节省UE功耗和小区选择时间，即读取一个或多个SIB消息，而不是全读。
