Description

一种保留资源的指示方法及设备
本申请要求于2018年01月12日提交中国专利局、申请号为201810033527.2、申请名称为“一种保留资源的指示方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，尤其涉及一种保留资源的指示方法及设备。
背景技术
随着通信技术的不断发展，第五代无线通信技术(the fifth Generation Telecommunication，5G)系统，即新无线接入技术(New Radio Access Technology，New RAT，NR)系统应运而生，其与演进型长期演进(Long Term Evolution-Advanced，LTE-A)系统相比，具有更大的单载波带宽和更灵活的部署频段。在短期内，LTE-A系统仍将继续为其用户设备(User Equipment，UE)提供无线通信服务，因此，LTE-A系统与NR系统在短期内会共享时频资源。并且，NR系统将在现有LTE-A系统频段上逐渐取代LTE-A系统。
另外，增强型机器类通信(enhanced Machine Type Communication，eMTC)系统及其其他演化系统(如，进一步eMTC(Further eMTC，FeMTC)系统；更进一步eMTC(Even Further eMTC，eFeMTC)系统)是在长期演进(Long Term Evolution，LTE)系统上衍生的系统，其在LTE系统的频段中进行工作。如，在下行(Downlink，DL)传输中，其使用LTE系统中的小区特定参考信号(Cell-specific Reference Signal，CRS)、主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)、物理广播信道(Physical Broadcast Channel，PBCH)，以及用于承载重要系统信息的带宽降低的系统信息块1(System Information Block 1-Bandwidth Reduced，SIB1-BR)。且，eMTC系统已经开始部署商用，由于eMTC UE具有低功耗、长休眠等特性，其电池寿命较长，预期可达10年左右。因此，可以预见的是，在NR系统在LTE-A系统频段上逐步取代LTE-A系统的过程中，eMTC UE依然在工作，这样，NR系统与eMTC系统很可能同时在同频段共存。这种情况下，NR系统需要考虑如何为eMTC系统保留时频资源(如，保留CRS、PSS、SSS、PBCH，以及SIB1-BR资源)，使得eMTC网络设备和eMTC UE可以正常工作。
在现有技术中，NR系统支持一种为LTE系统的CRS做资源保留的方法，具体为：NR系统可以通知NR UE用于为LTE系统中CRS做资源保留的配置信息，以便NR UE能够根据接收到的配置信息，确定出LTE系统中传输CRS需占用的资源粒子(Resource Element，RE)，从而避免在这些RE上接收有用信号。另外，NR系统还支持一种资源块-符号级(RB-symbol level)的资源保留方法，其可通过多个位图(bitmap)组合的方法通知NR UE哪些资源需要进行保留。
但是，现有技术仅支持LTE系统中CRS的资源保留，以及频域上资源块(Resource  Block，RB)级别的、周期不超过40毫秒(ms)的资源保留，无法精确为eMTC系统保留资源。

具体实施方式
本申请说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同对象，而不是用于限定特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了解决现有技术无法精确为通信系统保留资源的问题，本申请实施例提供一种保留资源的指示方法，其基本原理是：终端设备接收来自网络设备的保留资源指示信息；其中，所述保留资源指示信息包括第一时间偏移指示信息、第二时间偏移指示信息、第一指示信息和第二指示信息中的至少一个；第一时间偏移指示信息用于指示系统帧号偏移值，第二时间偏移指示信息用于指示子帧索引号偏移值或时隙索引号偏移值，第一指示信息用于指示物理广播信道的重复，第二指示信息用于指示带宽降低的系统信息块1的重复次数，第一时间偏移指示信息和/或第二时间偏移指示信息指示的时间范围小于或等于门限值，保留资源指示信息用于确定保留资源。终端设备根据来自网络设备的包括有第一时间偏移指示信息、第二时间偏移指示信息、第一指示信息和第二指示信息中的至少一个保留资源指示信息，能够精确的确定出需要为通信系统保留的资源。或者，终端设备根据来自网络设备的包括一个指示周期大于门限值的第一位图信息，或至少二个指示周期小于或等于所述门限值的第一位图信息的保留资源指示信息，也能够精确的确定出需要为通信系统保留的资源。终端设备不在保留资源上接收或发送数据。
下面将结合附图对本申请实施例的实施方式进行详细描述。
图1为本申请实施例提供的一种系统架构的简化示意图。其中，本申请可应用与 第一通信系统与第二通信系统共享时频资源，且第一通信系统与第二通信系统之间需要避免干扰(如，第一通信系统与第二通信系统同站址，或第一通信系统与第二通信系统异站址且基站的布局位置较近的场景)的场景。示例性的，第一通信系统可以是NR系统或者下一代无线通信系统，第二通信系统可以是eMTC系统、FeMTC系统、eFeMTC系统或者LTE系统等，本申请实施例在此不做具体限制。

网络设备11、网络设备14与终端设备12、终端设备13之间可以通过无线电波来进行通信，也可以通过可见光、激光、红外、光量子、电力线、光纤、同轴电缆、铜绞线等进行通信。
其中，网络设备11，具体的可以是基站。基站可以是无线通信的基站(Base Station，BS)或基站控制器等。也可以称为无线接入点，收发站，中继站，小区，发送接收点(Transmit and Receive Port，TRP)等等。具体的，网络设备11是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置，其可以与终端设备进行连接，接收终端设备发送的数据并发送给核心网设备。网络设备11的主要功能包括如下一个或多个功能：进行无线资源的管理、互联网协议(Internet Protocol，IP)头的压缩及用户数据流的加密、用户设备附着时进行MME的选择、路由用户面数据至服务网关(Service Gateway，SGW)、寻呼消息的组织和发送、广播消息的组织和发送、以移动性或调度为目的的测量及测量报告的配置等等。网络设备11可以包括各种形式的蜂窝基站、家庭基站、小区、无线传输点、宏基站、微基站、中继站、无线接入点等等。
在采用不同的无线接入技术的系统中，基站的名称可能会有所不同，例如，在LTE系统中，称为演进的基站(evolved NodeB，eNB或eNodeB)，在第3代移动通信技术(the third Generation Telecommunication，3G)系统中，称为基站(Node B)，在NR系统中，称为gNB，CU,DU等等，在无线本地接入系统中，称为接入点(Access Point)。随着通信技术的演进，这一名称可能会变化。此外，在其它可能的情况下，网络设备11可以是其它为终端设备提供无线通信功能的装置。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为网络设备。
终端设备12和终端设备13，均指的是包含无线收发功能，可以与接入网设备和/或核心网设备等网络侧设备配合为用户提供通讯服务的设备。终端设备12和终端设备13均可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(如，Radio Access Network，RAN)与一个或多个核心网或者互联网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)、计算机和数据卡，例如，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，它们与无线接入网交换语言和/或数据。例如，个人通信业务 (Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户站(Subscriber Station，SS)、用户端设备(Customer Premises Equipment，CPE)、UE等。例如，该终端设备可以手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、上网本、个人数字助理(Personal Digital Assistant，PDA)等等。作为一种实施例，如图1所示，本申请的系统架构包括的终端设备12和终端设备13均以手机为例示出。
在本申请实施例中，示例性的，以第一通信系统是NR系统，第二通信系统eMTC系统为例，图1所示的终端设备12可以是NR系统的UE，终端设备13可以是eMTC系统的UE，两者在同一个基站的服务范围内，基站可以通过向终端设备12发送保留资源指示信息，以便终端设备12为eMTC系统保留资源。

图2中示出的设备结构并不构成对网络设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
图3为本申请实施例提供的一种终端设备的组成示意图。如图3所示，该终端设备可以包括至少一个处理器31、存储器32、收发器33和总线34。
下面结合图3对终端设备的各个构成部件进行具体的介绍：
处理器31可以是一个处理器，也可以是多个处理元件的统称。例如，处理器31可以是一个通用CPU，也可以是ASIC，或一个或多个用于控制本申请方案程序执行的集成电路，例如：一个或多个DSP，或，一个或者多个FPGA。其中，处理器31可以通过运行或执行存储在存储器32内的软件程序，以及调用存储在存储器32内的数据，执行终端设备的各种功能。

图4为本申请实施例提供的一种保留资源的指示方法的流程图，该保留资源的指示方法应用于第一通信系统与第二通信系统共享时频资源，且第一通信系统与第二通信系统之间需要避免干扰的场景。如图4所示，该方法可以包括：
需要说明的是，为了便于本领域技术人员理解，本申请实施例以第一通信系统为NR系统，第二通信系统为eMTC系统，且NR系统需要为eMTC系统保留资源为例，对本申请实施例进行具体介绍，但本申请实施例并不限于此。其中，假设NR系统需要为eMTC系统保留CRS、PSS、SSS、PBCH，以及SIB1-BR资源中的一种或多种。
401、网络设备向终端设备发送保留资源指示信息。所述保留资源指示信息可以包括第一时间偏移指示信息、第二时间偏移指示信息、第一指示信息和第二指示信息中的至少一个。
其中，第一时间偏移指示信息用于指示系统帧号(System Frame Number，SFN)偏移值。系统帧号偏移值可以指的是NR系统的系统帧号与eMTC系统的系统帧号之间的偏移值。系统帧号偏移值也可以指的是NR系统的系统帧号与eMTC系统的系统帧号之间的偏移值对门限值取模的结果。
第二时间偏移指示信息用于指示子帧索引号偏移值或时隙(slot)索引号偏移值。子帧索引号偏移值可以指的是NR系统的子帧索引号与eMTC系统的子帧索引号之间的偏移值，时隙索引号偏移值可以指的是NR系统的时隙索引号与eMTC系统的子帧索引号之间的偏移值。子帧索引号偏移值也可以指的是NR系统的子帧索引号与eMTC系统的子帧索引号之间的偏移值对门限值取模的结果，时隙索引号偏移值也可以指的是NR系统的时隙索引号与eMTC系统的子帧索引号之间的偏移值对门限值取模的结果。
在本申请实施例中，第一时间偏移指示信息和/或第二时间偏移指示信息指示的时间范围小于或等于门限值。所述门限值可以小于或等于80ms。其中，该门限值是在确定需要保留的PSS、SSS、PBCH以及SIB1-BR资源时，NR系统与eMTC系统之间时域偏移的最大值。通过将第一时间偏移指示信息和/或第二时间偏移指示信息指示的时间范围限制在门限值内，可以有效的降低通知终端设备保留资源时的消息开销。需要说明的是，所述门限值的取值范围仅是本申请实施例提供的一种可能实现，在实际的应用场景中，该门限值的具体取值范围也可以根据实际应用场景的需求进行设置，例如，所述门限值可以小于或等于10240ms。
第一时间偏移指示信息和/或第二时间偏移指示信息用于指示对确定出的需保留的时频资源进行时域偏移，以确定出实际需要保留的时频资源。
第一指示信息用于指示物理广播信道(PBCH)的重复。示例性的，由于eMTC 系统是在LTE系统上衍生的系统，而在LTE系统中，对于特定的双工模式、特定的带宽而言，若PBCH需要重复，则其重复次数是固定的，因此，第一指示信息可以具体指示PBCH是否重复。在这种场景下，当第一指示信息指示PBCH重复，PBCH的重复次数可以根据双工模式和带宽指示信息指示的带宽确定。第一指示信息也可以具体指示PBCH的重复次数。
第二指示信息用于指示带宽降低的系统信息块1(SIB1-BR)的重复次数。该重复次数为在80ms周期中SIB1-BR重复发送的次数。
进一步的，所述保留资源指示信息还可以包括以下至少一种：带宽指示信息、物理小区标识(Physical cell identification，PCID)、第三指示信息、第四指示信息、第五指示信息、第六指示信息、第七指示信息、第八指示信息。
其中，带宽指示信息可以用于指示eMTC系统的带宽。PCID指的是eMTC系统的PCID。
第三指示信息用于指示第一子载波的频率位置。示例性的，第一子载波可以是eMTC系统的中心子载波。
第四指示信息用于指示小区特定参考信号(CRS)端口数。CRS为eMTC系统或LTE系统使用的参考信号。
第五指示信息用于指示多播单频网络(Multicast Broadcasting Single Frequency Network，MBSFN)子帧配置。
第六指示信息用于指示小区特定参考信号(CRS)偏移参数。CRS偏移参数可以用CRS V shift表示。
第七指示信息可用于指示eMTC系统的双工模式。双工模式包括：频分双工(Frequency Division Duplex，FDD)模式和时分双工(Time Division Duplex，TDD)模式。
第八指示信息可用于指示eMTC系统的循环前缀(Cyclic Prefix，CP)模式。CP模式包括：普通CP模式和长CP模式。
其中，由于eMTC系统是在LTE系统上衍生的系统，因此，带宽指示信息也可以用于指示LTE系统的带宽，第一子载波也可以是LTE系统的中心子载波，即第三指示信息用于指示LTE系统的中心子载波的频率位置，PCID也可以指的是LTE系统的PCID，第七指示信息也可用于指示LTE系统的双工模式，第八指示信息也可用于指示LTE系统的CP模式。
在一些实施例中，由于现有NR系统已经支持为LTE系统的CRS资源保留，因此，上述第三指示信息、带宽指示信息、第四指示信息、第五指示信息和第六指示信息可以包含在小区特定参考信号(CRS)指示信息中通过所述保留资源指示信息发送给终端设备。所述CRS指示信息用于确定CRS占用的资源。在一些实施例中，上述第三指示信息、带宽指示信息、第四指示信息、第五指示信息和第六指示信息也可以直接携带在保留资源指示信息中发送给终端设备。本申请实施例在此不做具体限制。
另外，需要说明的是，由于在LTE系统中，带宽为1.4MHz(兆赫兹)时，PBCH是不能重复发送的，因此，当带宽指示信息指示第一带宽，即指示的带宽为1.4MHz时，可以不指示PBCH的重复，即所述保留资源指示信息中可以不包括用于指示PBCH 重复的第一指示信息，以节省保留资源指示信息的开销。
由于在LTE系统中，带宽为1.4MHz或3MHz时，SIB1-BR的重复次数是固定的(4次)，因此，当带宽指示信息指示第一带宽或第二带宽，即指示的带宽为1.4MHz或3MHz时，可以不指示SIB1-BR的重复次数，即所述保留资源指示信息中可以不包括用于指示SIB1-BR的重复次数的第二指示信息，以节省保留资源指示信息的开销。
所述保留资源指示信息包括的第六指示信息是用于指示CRS偏移参数，即CRS V shift的，而CRS V shift可以利用PCID计算出来，因此，当所述保留资源指示信息包括PCID时，可以不指示CRS偏移参数，即所述保留资源指示信息中可以不包括用于指示CRS偏移参数的第六指示信息，以节省保留资源指示信息的开销。
当NR系统和eMTC系统的SFN和子帧索引号完全对齐时，所述保留资源指示信息中也可以不包括用于指示SFN偏移值的第一时间偏移指示信息和用于指示子帧索引号偏移值或时隙索引号偏移值的第二时间偏移指示信息，以节省保留资源指示信息的开销。
当NR系统和eMTC系统的SFN和子帧索引号完全对齐，eMTC系统的带宽等于1.4MHz时，所述保留资源指示信息中也可以不包括用于指示SFN偏移值的第一时间偏移指示信息、用于指示子帧索引号偏移值或时隙索引号偏移值的第二时间偏移指示信息、用于指示PBCH重复的第一指示信息以及用于指示SIB1-BR的重复次数的第二指示信息。
通常情况下，NR系统和eMTC系统的双工模式以及CP模式是相同的，因此，所述保留资源指示信息中也可以不包括用于指示eMTC系统的双工模式的第七指示信息和/或用于指示eMTC系统的CP模式的第八指示信息，以节省保留资源指示信息的开销。当所述保留资源信息不包括第七指示信息和/或第八指示信息时，可以根据NR系统的双工模式和/或CP模式，确定eMTC系统的双工模式和/或CP模式。另外，NR系统和eMTC系统通常使用的CP模式为普通CP模式。
当需要为eMTC系统保留资源时，网络设备可以向终端设备发送保留资源配置信息。其中，所述终端设备指的是NR系统中的终端设备。
402、终端设备接收来自网络设备的保留资源指示信息。
403、终端设备根据保留资源指示信息确定保留资源。
在终端设备接收到来自网络设备的保留资源指示信息之后，便可以根据接收到的保留资源指示信息和eMTC系统使用资源的映射关系确定需要为eMTC系统保留的CRS、PSS、SSS、PBCH，以及SIB1-BR的资源中的一种或多种。
示例性的，终端设备确定需为CRS保留的资源需用以下指示信息：用于指示第一子载波(如中心子载波)的频率位置的第三指示信息、带宽指示信息、用于指示CRS端口数的第四指示信息、用于指示MBSFN子帧配置的第五指示信息以及用于指示CRS偏移参数(CRS V shift)的第六指示信息。根据这些信息终端设备便可以确定出CRS所占用的RE，即可确定出需要为CRS保留的资源。
其中，中心子载波的频率位置和带宽指示信息所指示的带宽用于终端设备确定CRS的频率范围以及CRS V shift的变化。CRS V shift的变化主要是由于LTE系统的中心子载波不是有效的传输载波，但在NR系统中，中心子载波是有效的传输载波引起的， 可用于后续确定CRS所占用的RE。
CRS端口数和CRS V shift用于终端设备确定CRS在一个“子帧(时域)·RB(频域)”范围所占用的RE。其中，CRS端口数可以为1、2或4。CRS V shift的取值可以是0-5。
MBSFN子帧配置用于终端设备确定在确定出的RE中，哪些RE上需要为CRS保留资源。由于在LTE系统的MBSFN子帧上是不发送CRS的，因此在这些MBSFN子帧上不需要为CRS保留资源。在本申请实施例中，不同的CRS端口数对应的需要为CRS保留的资源可以如图5所示。
另外，在本申请实施例中，当所述保留资源指示信息包括PCID，不包括用于指示CRS偏移参数(CRS V shift)的第六指示信息时，CRS V shift可以根据PCID，利用公式(1)计算得到：
Figure PCTCN2019071496-appb-000001
其中，
Figure PCTCN2019071496-appb-000002
为PCID。
终端设备确定需为PSS/SSS保留的资源需用以下指示信息：用于指示第一子载波(如，中心子载波)的频率位置的第三指示信息、用于指示子帧索引号偏移值或时隙索引号偏移值的第二时间偏移指示信息、用于指示eMTC系统的双工模式的第七指示信息以及用于指示eMTC系统的CP模式的第八指示信息。根据这些信息终端设备便可以确定出PSS/SSS所占用的资源，即可确定出需要为CRS保留的资源。
其中，由于在时域上eMTC系统和NR系统仅能保证子帧边界是对齐的(其中，一个子帧为1ms长，对于15kHz子载波间隔的NR系统而言，1ms也正好是1个slot的长度)，但不能保证一个eMTC系统的无线帧(10ms)内的10个子帧的子帧号与一个NR系统的无线帧内的10个子帧的子帧号是对齐的。例如，如图6所示，eMTC系统和NR系统的子帧在一个无线帧的子帧号相差3，并没有对齐。因此，为了能够精确为PSS/SSS保留资源，需要指示子帧索引号偏移值(或时隙索引号偏移值)。另外，由于PSS/SSS的周期为5个子帧，因此，子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-4。其中，对于大于或等于5的子帧偏移值(如子帧偏移值为N)情况，子帧偏移值为N的情况下PSS/SSS所占的资源与“N mod 5”情况下PSS/SSS所占的资源是相同的，“mod”表示取模运算。
目前，PSS/SSS的持续时间以及频域宽度(6RB+1中心子载波＝73个子载波)是固定的。
具体的，PSS/SSS在时域上占1个符号长，周期为5个子帧。具体的时域位置与LTE系统的双工模式、CP模式有关。例如，如图7所示，当双工模式为FDD模式时，PSS在一个系统帧中占0号子帧和5号子帧的第7个符号，SSS在一个系统帧中占0号子帧和5号子帧的第6个符号。当双工模式为TDD模式时，PSS在一个系统帧中占1号子帧和6号子帧的第3个符号，SSS在一个系统帧中占0号子帧和5号子帧的第14个符号。
PSS/SSS在频域上以LTE系统的中心子载波为中心，占连续的73个子载波，其中含中心子载波，两端各还有若干子载波留空作为保护带。
其中，中心子载波的频率位置用于终端设备确定为PSS/SSS保留的资源的频率范 围。
子帧索引号偏移值或时隙索引号偏移值、双工模式以及CP模式用于终端设备确定为PSS/SSS保留的资源的时间范围。
示例性的，以第一子载波为eMTC系统的中心子载波，eMTC系统的双工模式为FDD模式、CP模式为普通CP模式为例，终端设备根据上述信息确定PSS/SSS的保留资源具体的可以是：
终端设备可以根据LTE系统的中心子载波的频率位置，确定PSS和SSS的频域的中心位置。根据PSS和SSS的频域宽度(6RB+1中心子载波＝73个子载波)，即在频域上占连续的73个子载波和PSS和SSS的频域的中心位置，确定出为PSS和SSS在频域上所占的资源，即确定需保留的资源的频率范围。终端设备根据现有标准(TS36.211)对FDD模式和普通CP模式的规定，确定PSS在时域上占每个无线帧的0号子帧和5号子帧的第7个符号(即符号6)，确定SSS在时域上占每个无线帧的0号子帧和5号子帧的第6个符号(即符号5)，即确定出PSS和SSS在时域上所占的资源，即确定需保留的资源的时间范围。结合确定出的需保留的资源的频率范围和时间范围即可确定需保留的时频资源。根据子帧索引号偏移值或时隙索引号偏移值对确定出的需保留的时频资源进行时域偏移，便可以确定出实际需要为PSS/SSS保留的时频资源。
需要说明的是，确定需为PSS/SSS保留的资源需用的指示信息中：帧索引号偏移值或时隙索引号偏移值，也可以替换为系统帧号偏移值，或者系统帧号偏移值和子帧索引号偏移值或时隙索引号偏移值的叠加，本申请实施例在此不做具体限制。例如，当SFN偏移值来代替子帧/时隙索引号偏移值时，如可以用0、0.1、0.2、0.3、0.4个SFN偏移来表示0-4的子帧/时隙索引号偏移值。
当所述保留资源指示信息中不包括双工模式时，终端设备可以假设eMTC系统的双工模式与NR系统的双工模式是相同的。当所述保留资源指示信息中不包括CP模式时，终端设备可以假设eMTC系统的CP模式与NR系统的双工模式是相同的。从而利用双工模式和CP模式确定出需要为PSS/SSS保留的资源的时间范围。
终端设备确定需为PBCH保留的资源需用以下指示信息：用于指示第一子载波(如中心子载波)的频率位置的第三指示信息、用于指示子帧索引号偏移值或时隙索引号偏移值的第二时间偏移指示信息、用于指示PBCH的重复的第一指示信息、带宽指示信息、用于指示eMTC系统的双工模式的第七指示信息以及用于指示eMTC系统的CP模式的第八指示信息。根据这些信息终端设备便可以确定出PBCH所占用的资源，即可确定出需要为PBCH保留的资源。
其中，由于在时域上eMTC系统和NR系统仅能保证子帧边界是对齐的，但不能保证一个eMTC系统的无线帧内的10个子帧的子帧号与一个NR系统的无线帧内的10个子帧的子帧号是对齐的。因此，为了能够精确为PBCH保留资源，需要指示子帧索引号偏移值(或时隙索引号偏移值)。另外，由于PBCH的周期(如果需要重复的话，包括重复的PBCH部分)为10个子帧，因此，子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-9。其中，对于大于或等于10的子帧偏移值(如子帧偏移值为N)情况，子帧偏移值为N的情况下PBCH所占的资源与“N mod 10”情况下 PBCH所占的资源是相同的。
用于指示PBCH的重复的第一指示信息可以包含1比特，用于指示eMTC系统中的PBCH是否进行重复发送。其中，若第一指示信息用于指示重复发送PBCH，则终端设备可以根据双工模式和带宽指示信息所指示的带宽确定出重复次数。在不同双工模式下，不同带宽对应的重复次数是固定的。当然，用于指示PBCH的重复的第一指示信息也可以直接指示PBCH的重复次数，本申请实施例在此并不做具体限制。
目前，PBCH的持续时间和频域宽度(6RB+1中心子载波＝73个子载波)是固定的。
PBCH在时域上占4个符号长(0号子帧的第8-11个符号)，周期为10个子帧(即一个无线帧)。具体的时域位置与LTE系统的CP模式有关。
PBCH在频域上以LTE系统的中心子载波为中心，占连续的73个子载波，其中含中心子载波。若需要重复发送PBCH，则其重复的部分所占用的资源与双工模式和带宽指示信息指示的带宽有关。
其中，中心子载波的频率位置用于终端设备确定为PBCH保留的资源的频率范围。
用于指示PBCH的重复的第一指示信息用于终端设备确定PBCH是否重复，或者确定PBCH的重复次数。
当PBCH不重复时，子帧索引号偏移值或时隙索引号偏移值以及CP模式用于终端设备确定为PBCH保留的资源的时间范围。
当PBCH重复时，子帧索引号偏移值或时隙索引号偏移值以及CP模式用于终端设备确定为核心部分的PBCH保留的资源的时间范围，子帧索引号偏移值或时隙索引号偏移值、带宽指示信息以及双工模式用于终端设备确定为重复部分的PBCH保留的资源的时间范围。
示例性的，以eMTC系统的双工模式为FDD模式，CP模式为普通CP模式，第一子载波为eMTC系统的中心子载波，LTE系统的带宽等于5MHz，PBCH需要重复发送为例，终端设备根据上述信息确定PBCH的保留资源具体的可以是：
终端设备可以根据中心子载波的频率位置，确定PBCH的频域中心位置。根据PBCH的频域宽度(6RB+1中心子载波＝73个子载波)，即在频域上占连续的73个子载波和PBCH的频域的中心位置，确定出PBCH在频域上所占的资源，即确定需保留的资源的频率范围。终端设备根据现有标准中对FDD模式的规定，确定PBCH的“核心部分”在时域上占每个无线帧的0号子帧的符号7、8、9、10。根据LTE系统的带宽为5MHz，确定PBCH可以重复发送(此步也可以省略，因为若LTE系统的带宽＝1.4MHz，则PBCH重复指示信息应该总是指示“不重复”)。根据PBCH重复指示信息，确定PBCH重复发送。根据现有标准中FDD模式的规定，确定PBCH的“重复发送部分”在每个无线帧的0号子帧的符号3、4、11、12、13，以及每个无线帧的9号子帧的符号3、4、5、6、7、8、9、10、11、12、13。根据确定出的“核心部分”和“重复发送部分”在时域上所占用的资源，可确定出PBCH在时域上所占的资源，即确定需要保留的资源的时间范围，其中包括PBCH的核心部分和重复发送部分。结合确定出的需保留的资源的频率范围和时间范围，即可确定需保留的时频资源。进一步地，根据子帧索引号偏移值或时隙索引号偏移值对确定出的需保留的时频资源进行 时域偏移，便可以确定出实际需要为PBCH保留的时频资源。
需要说明的是，确定需为PBCH保留的资源需用的指示信息中：子帧索引号偏移值或时隙索引号偏移值，也可以替换为系统帧号偏移值，或者系统帧号偏移值和子帧索引号偏移值或时隙索引号偏移值的叠加，本申请实施例在此不做具体限制。
当所述保留资源指示信息中不包括双工模式时，终端设备可以假设eMTC系统的双工模式与NR系统的双工模式是相同的。当所述保留资源指示信息中不包括CP模式时，终端设备可以假设eMTC系统的CP模式与NR系统的双工模式是相同的。从而利用双工模式和CP模式确定出需要为PBCH保留的资源的时间范围。
终端设备确定需为SIB1-BR保留的资源需用以下指示信息：用于指示第一子载波(如中心子载波)的频率位置的第三指示信息、用于指示SFN偏移值的第一时间偏移指示信息、用于指示子帧索引号偏移值或时隙索引号偏移值的第二时间偏移指示信息、带宽指示信息、用于指示SIB1-BR的重复次数的第二指示信息、PCID、用于指示eMTC系统的双工模式的第七指示信息以及用于指示eMTC系统的CP模式的第八指示信息。根据这些信息终端设备便可以确定出SIB1-BR所占用的资源，即可确定出需要为SIB1-BR保留的资源。
其中，由于在时域上eMTC系统和NR系统仅能保证子帧边界是对齐的，但不能保证一个eMTC系统的无线帧内的10个子帧的子帧号与一个NR系统的无线帧内的10个子帧的子帧号是对齐的，可能也不能保证无线帧号也是对齐的。例如，结合图6所示，K不一定等于L。因此，为了能够精确为SIB1-BR保留资源，需要指示子帧索引号偏移值(或时隙索引号偏移值)和SFN偏移值。另外，由于SIB1-BR具有一个80ms(8个无线帧)周期的时频样式，因此SFN偏移值的取值范围可以为0-7，需要一个3比特信息来指示。子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-9，需要一个4比特信息来指示。另外，也可以单独用一个子帧索引号偏移值(或时隙索引号偏移值)来指示时域上的偏移，此时，子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-79。或者，单独用一个SFN偏移值来指示时域上的偏移，SFN偏移值的取值范围可以为0.0-7.9，步径为0.1。
目前，一个SIB1-BR的持续时间以及频域宽度(1NB＝6RB＝72个子载波)是固定的。
具体的，SIB1-BR在时域上占1个子帧中的后X个符号。其中，SIB1-BR在1个子帧中的起始符号可以根据LTE系统的带宽确定。如，LTE系统的带宽>10个RB时，起始符号索引为3，X＝11，LTE系统的带宽≤10个RB时，起始符号索引为4，X＝10。且SIB1-BR是在一个80ms周期中重复发送的，在该80ms周期中的重复次数的可能取值为4、8、16。如图8所示，为一个SIB1-BR的重复次数为4次、LTE系统的带宽大于10MHz时所占的资源的简单示意图。
SIB1-BR在频域占一个NB(也即6个连续的RB，即72个子载波)的宽度，而且频域位置是根据PCID、SIB1-BR的重复次数、LTE系统的带宽以及双工模式确定的。
其中，带宽指示信息用于终端设备确定SIB1-BR在时域上一个子帧中的起始符号，即确定X。
中心子载波的频率位置、带宽指示信息以及PCID用于终端设备确定为SIB1-BR 保留的资源的频率范围。
SIB1-BR的重复次数，带宽指示信息，系统帧号偏移值，子帧索引号偏移值或时隙索引号偏移值，PCID以及双工模式用于终端设备确定为SIB1-BR保留的资源的时间范围。
也就是说，终端设备可以根据中心子载波的频率位置、带宽指示信息以及PCID，并结合SIB1-BR的频域宽度(一个NB)确定出为SIB1-BR保留的资源的频率范围。终端设备根据带宽指示信息所指示的带宽确定SIB1-BR在时域上一个子帧中的起始符号，即确定X，并根据X、SIB1-BR的重复次数，带宽指示信息所指示的带宽，PCID以及双工模式确定出SIB1-BR的时域位置，并根据系统帧号偏移值，以及子帧索引号偏移值或时隙索引号偏移值便可以确定出实际需要为SIB1-BR保留的资源的时间范围。这样，便可确定出需要为SIB1-BR保留的资源。另外，由于SIB1-BR是具有跳频的，因此，上述确定出的频率范围和时间范围不是完全独立的。例如，示例性的，确定出的时域资源是1,2，频域资源是a，b，则可能确定出的传输资源是{1a，2b}，而不是{1a，1b，2a，2b}。
示例性的，以第一子载波为eMTC系统的中心子载波，eMTC系统的双工模式为FDD模式，CP模式为普通CP模式，LTE系统的带宽等于20MHz，SIB1-BR的重复发送次数为4次为例，终端设备根据上述信息确定SIB1-BR的保留资源具体的可以是：
终端设备可以根据中心子载波的频率位置确定SIB1-BR所在时频资源的参照频率或参照载波。
终端设备根据LTE系统的带宽＝20MHz以及现有标准协议(TS 36.211)的规定，确定“一个”SIB1-BR占的时域资源为一个子帧的后11个符号，占的频域资源为一个NB，也即占的频域资源包括连续的72个子载波。
终端设备根据现有标准协议(TS 36.211)的规定、LTE系统的带宽和PCID，确定SIB1-BR在80ms周期中进行跳频时所占的NB数以及跳频的顺序。
具体地可以是：终端设备根据现有标准协议(TS 36.211)的规定，以及根据LTE系统的带宽(LTE系统的带宽＝20MHz)和PCID，确定其跳频时所占的NB数为4。根据PCID和跳频时所占的NB数，结合下述公式可以确定在跳频过程中的跳频顺序。
n NB＝s j

其中，{s j}表示在LTE系统中的NB集合，{s j}中不包括与中心72个有效子载波重叠的NB。

Figure PCTCN2019071496-appb-000006
也即{s i}包括14个NB。NB按频率从低到高编号成NB0、NB1、……NB13。对于LTE系统带宽为20MHz的情况，跳频窄带数m＝4。进一步，可以根据PCID和公式
Figure PCTCN2019071496-appb-000007
确定SIB1-BR在80ms周期中进行跳频所使用的NB的顺序。
终端设备根据标准协议(TS 36.211)中对FDD模式的规定、LTE系统的带宽、PCID和SIB1-BR的重复次数确定SIB1-BR在80ms周期中所占的子帧(和顺序)。
具体的，当LTE系统的带宽＝20MHz时，根据表1可以确定SIB1-BR在80ms周期中所占的子帧，其中
Figure PCTCN2019071496-appb-000008
表示下行带宽所包括的RB数。
表1
Figure PCTCN2019071496-appb-000009
时SIB1-BR的帧和子帧的集合
Figure PCTCN2019071496-appb-000010
其中，FDD模式使用的帧结构类型为帧结构类型1(Frame structure type 1)，TDD模式使用的帧结构类型为帧结构类型2(Frame structure type 2)。
由于LTE系统的带宽不为1.4MHz或3MHz，因此可以确定SIB1-BR的重复次数可以不为4(此步也可以省略，因为若LTE系统的带宽＝1.4MHz或3MHz，则SIB1-BR重复指示信息应总是指示“4”)。终端设备根据SIB1-BR的重复次数指示信息，确定SIB1-BR的重复次数为4次，也即可以确定使用上表中重复次数(也即
Figure PCTCN2019071496-appb-000011
)为4所对应的行。
这样，结合表1，终端设备根据PCID，确定使用SIB1-BR的重复次数为4次的2行中的第1行或第2行。以PCID为偶数为例，此时
Figure PCTCN2019071496-appb-000012
使用第一行。最终根据表1可以确定SIB1-BR在80ms周期中所占的子帧为：每个偶数无线帧的子帧4。由于80ms中包含8个无线帧，可以分别标记为无线帧0，无线帧1，……无线帧7，则可以确定SIB1-BR占无线帧0、无线帧2、无线帧4、无线帧6的子帧4，顺序则为时域上的先后顺序。
结合所确定的需保留的资源的时间范围和频率范围即可确定SIB1-BR在80ms周期中所占的时频资源，即确定需保留的时频资源。
例如，若确定出的SIB1-BR的NB数和NB的顺序为NB4、NB8、NB12、NB2，SIB1-BR使用的子帧和子帧顺序为无线帧0、无线帧2、无线帧4、无线帧6的子帧4，确定出的SIB1-BR使用一个子帧中的符号3、4、5、6、7、8、9、10、11、12、13，则SIB1-BR在80ms周期中所占用的时频资源为下述4个资源的集合。
资源1、时域：无线帧0的子帧4中的符号3-13，频域：NB4
资源2、时域：无线帧2的子帧4中的符号3-13，频域：NB8
资源3、时域：无线帧4的子帧4中的符号3-13，频域：NB12
资源4、时域：无线帧6的子帧4中的符号3-13，频域：NB2
根据系统帧号偏移值，以及子帧索引号偏移值或时隙索引号偏移值对确定出的需保留的时频资源进行时域偏移，并根据确定出的中心子载波或参照频率对确定出的需保留的时频资源进行频域偏移，便可以确定出实际需要为SIB1-BR保留的时频资源。 需要说明的是，确定需为SIB1-BR保留的资源需用的指示信息中：系统帧号偏移值和子帧索引号偏移值或时隙索引号偏移值的叠加，也可以替换为帧索引号偏移值或时隙索引号偏移值，还可以替换为系统帧号偏移值，本申请实施例在此不做具体限制。
由于SIB1-BR在不同的带宽下有不同的可重复次数和传输跳频窄带数，因此在不同带宽、不同的重复次数下，SIB1-BR在80ms周期内的时频资源的重复周期也不相同，所以系统帧号偏移值和/或子帧索引号偏移值或时隙索引号偏移值指示的时间范围的门限值的最小取值范围也不同，若偏移值指示的时间范围的门限值的范围小于一个最小取值，则会导致无法精确表示保留资源的时域偏移。在不同的重复次数和带宽下的偏移值指示的时间范围的最小取值可以如表2所示。
表2
Figure PCTCN2019071496-appb-000013
可见，在不同带宽下，偏移值指示的时间范围的最小取值不同，但最小取值的最大值不超过80ms。因此，在本申请实施例中，80ms可以作为系统帧号偏移值和/或子帧索引号偏移值或时隙索引号偏移值指示的时间范围的门限值。另外，也可以在不同带宽、不同重复次数下有不同的门限值，如在系统带宽为10MHz、SIB1-BR重复次数为4时，系统帧号偏移值和/或子帧索引号偏移值或时隙索引号偏移值指示的时间范围的门限值为40ms，这样可以缩小指示范围，进一步减少指示开销。又或者，偏移值指示的时间范围门限值可以为系统帧号可取值的最大值的时间10240ms，这样可以精确指示系统帧索引号和/或子帧索引号或时隙索引号的偏移量。
当LTE系统的带宽小于或等于3MHz时，SIB1-BR的重复次数固定的4次，因此，所述保留资源指示信息中不包括用于指示SIB1-BR的重复次数的第二指示信息，终端设备可以根据带宽指示信息所指示的带宽确定出重复次数。当LTE系统的带宽大于3MHz时，SIB1-BR的重复次数可能为4、8、16，此时，需要一个2比特信息指示SIB1-BR的重复次数。另外，在标准协议(TS 36.213)中规定，在LTE系统中可以使用一个5比特的SIB1-BR调度信息(schedulingInfoSIB1-BR)来指示SIB1-BR的重复次数和传输块大小，在本申请实施例中可以沿用schedulingInfoSIB1-BR来指示SIB1-BR的重复次数。
当所述保留资源指示信息中不包括双工模式时，终端设备可以假设eMTC系统的双工模式与NR系统的双工模式是相同的。当所述保留资源指示信息中不包括CP模式 时，终端设备可以假设eMTC系统的CP模式与NR系统的双工模式是相同的。从而利用双工模式和CP模式确定出需要为SIB1-BR保留的资源的时间范围。
综合考虑上述确定PSS、SSS、PBCH，以及SIB1-BR的保留资源所需的第一时间偏移指示信息和/或第二时间偏移指示信息，可以确定出第一时间偏移指示信息的取值单位和/或第二时间偏移指示信息的取值范围。例如，当保留资源指示信息包括第一时间偏移指示信息和第二时间偏移指示信息时，第一时间偏移指示信息的指示的SFN偏移值的取值范围可以为0-7，第二时间偏移指示信息指示的子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-9。当保留资源指示信息包括第一时间偏移指示信息时，第一时间偏移指示信息的指示的SFN偏移值的取值范围可以为0.0-7.9，步进为0.1。当保留资源指示信息包括第二时间偏移指示信息时，第二时间偏移指示信息指示的子帧索引号偏移值(或时隙索引号偏移值)的取值范围可以为0-79。
需要说明的是，本发明也可以为eMTC系统保留CRS、PSS、SSS、PBCH、SIB1-BR中的一种或多种所占的资源。例如，当NR系统仅为eMTC系统保留PSS、SSS、PBCH、SIB1-BR所占资源时，保留资源指示信息可以包括物理小区标识、第一时间偏移指示信息、第二时间偏移指示信息、带宽指示信息、第一指示信息、第二指示信息和第三指示信息。又例如，当NR系统仅为eMTC系统保留CRS、PSS、SSS、PBCH所占的资源时，保留资源指示信息可以包括第二时间偏移指示信息、带宽指示信息、第一指示信息、第三指示信息、第四指示信息、第五指示信息和第六指示信息。再例如，当NR系统仅为eMTC系统保留SIB1-BR所占的资源时，保留资源指示信息可以包括物理小区标识、第一时间偏移指示信息、第二时间偏移指示信息、带宽指示信息、第二指示信息和第三指示信息。再例如，当NR系统仅为eMTC系统保留PSS、SSS、PBCH所占的资源时，保留资源指示信息可以包括第二时间偏移指示信息、第一指示信息和第三指示信息。此外，在上述可能的实现方式中，保留资源指示信息还可以包括第七指示信息和/或第八指示信息。在具体的实现中，保留资源指示信息需要包括的指示可以根据具体应用场景的需求进行配置，本申请实施例在此并不做具体限制。
本申请实施例提供的保留资源的指示方法，终端设备根据来自网络设备的包括有第一时间偏移指示信息、第二时间偏移指示信息、第一指示信息和第二指示信息中的至少一个保留资源指示信息，能够精确的确定出需要为通信系统保留的资源。
图9为本申请实施例提供的一种保留资源的指示方法的流程图，该保留资源的指示方法应用于第一通信系统与第二通信系统共享时频资源，且第一通信系统与第二通信系统之间需要避免干扰的场景。如图9所示，该方法可以包括：
需要说明的是，为了便于本领域技术人员理解，本申请实施例以第一通信系统为NR系统，第二通信系统为eMTC系统，且NR系统需要为eMTC系统保留资源为例，对本申请实施例进行具体介绍，但本申请实施例并不限于此。其中，假设NR系统需要为eMTC系统保留CRS、PSS、SSS、PBCH，以及SIB1-BR资源中的一种或多种。
501、网络设备向终端设备发送保留资源指示信息。所述保留资源指示信息可以包括一个指示周期大于门限值的第一位图信息，或者，所述保留资源指示信息可以包括至少二个指示周期小于或等于门限值的第一位图信息。
所述门限值为40毫秒。
进一步的，所述保留资源指示信息还可以包括：子载波偏移指示信息、第二位图信息和第三位图信息，或者，所述保留资源指示信息还可以包括：连续子载波指示信息和第二位图信息。
其中，子载波偏移指示信息用于指示子载波的频率位置偏移值。
连续子载波指示信息用于指示第一子载波的频率位置和包括第一子载波的连续子载波数。所述第一子载波可以是eMTC系统的中心子载波，也可以是eMTC系统的起始子载波。
子载波偏移指示信息和连续子载波指示信息均用于指示对确定出的需保留的时频资源进行子载波级的频域偏移，以确定出实际需要保留的时频资源。
第二位图信息用于指示资源在一个时隙或两个时隙内所占用的符号。第二位图信息(如，用bitmap2表示)是符号等级的位图(symbol-level-bitmap)，用于确定在时域上哪些符号需要作为保留资源。
第三位图信息用于指示资源所占的资源块。第三位图信息(如，用bitmap3表示)是RB等级的位图(RB-level-bitmap)，用于确定在频域上哪些RB需要作为保留资源。例如，如图10所示，假设在频域上共有8个RB需要指示，则bitmap的长度为8，以“1”表示对应的RB需要保留，“0”表示对应的RB不需要保留为例，bitmap3＝{01000001}，其用于表示第2个和第8个RB需要作为保留资源。
第二位图信息和第三位图信息可以结合到一起，共同确定在一定时域和频域范围内的保留资源。例如，在普通CP长度下，一个slot有14个符号；以“1”表示对应的符号需要保留，“0”表示对应的符号不需要保留为例，假设bitmap2＝{10000001000000}，bitmap3＝{01000001}，则如图11所示，表示了bitmap3-bitmap2结合到一起确定的在“时域一个slot*频域8个RB”内的保留资源。
在本申请实施例中，第一位图信息(如，用bitmap1表示)用于将上述bitmap3-bitmap2确定的保留资源扩展到一个更大的时域周期中。bitmap1可以包括{1,5,10,20,40}个bitmap2中的时间总长单位。其中，若bitmap2指示的是1个slot内的符号，则bitmap1中的单位是1个slot；若bitmap2指示的是2个slot内的符号，则bitmap1中的单位是2个slot。例如，以“1”表示需要保留，“0”不需要保留为例，如，bitmap1＝{10101}，则如图12所示，表示了由bitmap1-bitmap2-bitmap3确定出的保留资源。其中，第1个时隙，第3个时隙以及第5个时隙的具体样式如图11所示，第2个时隙和第4个时隙的所有资源均不需要保留。可以得到的是，bitmap1是一个时隙等级(slot-level)，或两个时隙等级(2slot-level)的位图。bitmap1与bitmap3-bitmap2的组合可以把由bitmap3-bitmap2所确定的“一个slot*M个RB”范围内的保留资源扩展到更大的周期去。
如图13所示，考虑到eMTC系统和NR系统在频域上仅能保证eMTC子载波与NR子载波对齐，而不能保证RB的边界对齐，因此，在本申请实施例中，网络设备向终端设备发送的保留资源指示信息除了包括一个指示周期大于门限值的第一位图信息，或者，所至少二个指示周期小于或等于门限值的第一位图信息外，还可以包括子载波偏移指示信息、第二位图信息和第三位图信息，或者，还可以包括：连续子载波指示信息和第二位图信息，以便终端设备精确的确定保留资源。其中，第一位图信息、第 二位图信息和/或第三位图信息是由网络设备根据确定出的需要为eMTC系统保留的资源确定的。
进一步的，为了使得终端设备能够确定出为CRS保留的资源，所述保留资源指示信息还可以包括以下至少一种：带宽指示信息、第一指示信息、第二指示信息、第三指示信息、第四指示信息。
带宽指示信息可以用于指示eMTC系统的带宽。
第一指示信息用于指示第二子载波的频率位置。示例性的，第二子载波可以是eMTC系统的中心子载波。
第二指示信息用于指示小区特定参考信号(CRS)端口数。
第三指示信息用于指示多播单频网络(MBSFN)子帧配置，
第四指示信息用于指示小区特定参考信号(CRS)偏移参数。CRS偏移参数可以用CRS V shift表示。
其中，由于eMTC系统是在LTE系统上衍生的系统，因此，带宽指示信息也可以用于指示LTE系统的带宽，第二子载波也可以是LTE系统的中心子载波，即第一指示信息用于指示LTE系统的中心子载波的频率位置。
当需要为eMTC系统保留资源时，网络设备可以向终端设备发送保留资源配置信息。其中，所述终端设备指的是NR系统中的终端设备。
502、终端设备接收来自网络设备的保留资源指示信息。
503、终端设备根据保留资源指示信息确定保留资源。
在终端设备接收到来自网络设备的保留资源指示信息之后，便可以根据接收到的保留资源指示信息确定需要为eMTC系统保留的CRS、PSS、SSS、PBCH，以及SIB1-BR的资源中的一种或多种。
示例性的，终端设备确定需为CRS保留的资源需用以下指示信息：用于指示第二子载波(如中心子载波)的频率位置的第一指示信息、带宽指示信息、用于指示CRS端口数的第二指示信息、用于指示MBSFN子帧配置的第三指示信息以及用于指示CRS偏移参数(CRS V shift)的第四指示信息。根据这些信息终端设备便可以确定出CRS所占用的RE，即可确定出需要为CRS保留的资源。
需要说明的是，本申请实施例中对于CRS保留资源的确定方法与本申请图4所示的实施例中对于CRS保留资源的确定方法类似，其具体描述可以参考图4所示实施例中的相应内容，本申请实施例在此不在详细赘述。
终端设备确定需为PSS/SSS/PBCH保留的资源需用以下指示信息：一个指示周期小于或等于门限值的第一位图信息、第二位图信息以及连续子载波指示信息。
因为用于指示频域资源位置的第三位图信息(即上述bitmap3)是RB等级的位图，即仅能指示整数个RB的资源是否需要保留，而PSS/SSS/PBCH所占的子载波数为73(6RB+1SC)，且eMTC系统和NR系统的RB边界可能是不对齐的。此时，网络设备可以通过一个指示周期小于或等于门限值的第一位图信息、第二位图信息和连续子载波指示信息来指示需要为PSS/SSS/PBCH保留的资源。
其中，连续子载波指示信息具体可以包括以下两种实现方式：
方式一：连续子载波指示信息具体的可以是一个资源指示值(Resource indicator  Value，RIV)，该RIV用于指示第一子载波的频率位置和包括第一子载波的连续子载波数。例如，RIV具体用于指示需要保留的资源的频率范围的起始子载波的位置信息和包括起始子载波的连续子载波数，或者RIV具体用于指示需要保留的资源的频率范围的中心子载波的位置信息和包括中心子载波的连续子载波数。不同RIV对应的第一子载波和包括第一子载波的连续子载波数是不同的。
方式二：连续子载波指示信息具体的可以是具体的第一子载波的位置信息和包括第一子载波的连续子载波数。例如，连续子载波指示信息是具体的中心子载波的位置信息和包括中心子载波的连续子载波数，或者连续子载波指示信息是具体的起始子载波的位置信息和包括起始子载波的连续子载波数。
需要说明的是，由于各信道需要保留的连续子载波数通常是固定的，因此，在本申请实施例中，可以不通知连续子载波数，仅通知第一子载波的位置信息，即连续子载波指示信息可以仅只是第一子载波的频率位置即可。
终端设备利用连续子载波指示信息确定需要保留的资源的频率范围，并根据一个指示周期小于或等于门限值的第一位图信息和第二位图信息确定需要保留的时域资源，从而确定出需要为PSS/SSS/PBCH保留的资源。
另外，终端设备确定需为PSS/SSS/PBCH保留的资源也可以用以下指示信息：一个指示周期小于或等于门限值的第一位图信息、第二位图信息、第三位图信息以及子载波偏移指示信息。在这种情况下，终端可以在根据第一位图信息、第二位图信息和第三位图信息确定的资源的基础上，根据子载波偏移指示信息进行一个子载波偏移，以确定需要为PSS/SSS/PBCH保留的资源。
终端设备确定需为SIB1-BR保留的资源需用以下指示信息：一个指示周期大于门限值的第一位图信息或至少二个指示周期小于或等于门限值的第一位图信息、第二位图信息以及连续子载波指示信息。
或者，终端设备确定需为SIB1-BR保留的资源需用以下指示信息：一个指示周期大于门限值的第一位图信息或至少二个指示周期小于或等于门限值的第一位图信息、第二位图信息、第三位图信息以及子载波偏移指示信息。
其中，对于连续子载波指示信息的具体描述，与上述确定PSS/SSS/PBCH保留的资源时对连续子载波指示信息的具体描述类似，本申请实施例在此不再详细赘述。
在本申请实施例中，对于第一位图信息，即上述bitmap1，为了能够使得指示周期大于40ms，可达到80ms，网络设备可以通过串行的方法指示至少两个指示周期小于或等于门限值(如40ms)的第一位图信息，以实现在1slot或2slot中的保留资源的周期扩展。终端设备根据至少两个指示周期小于或等于门限值(如40ms)的第一位图信息，并结合第二位图信息以及连续子载波指示信息，或结合第二位图信息、第三位图信息以及子载波偏移指示信息，便可以确定需要为SIB1-BR保留的资源。网络设备也可以通过一个指示周期大于门限值(如40ms)的第一位图信息，来实现在1slot或2slot中的保留资源的周期扩展。终端设备根据一个指示周期大于门限值的第一位图信息，并结合第二位图信息以及连续子载波指示信息，或结合第二位图信息、第三位图信息以及子载波偏移指示信息，便可以确定需要为SIB1-BR保留的资源。
例如，假设网络设备指示SIB1-BR时的配置为：{SC_offset，bitmap3，bitmap2， bitmap1_a，bitmap1_b}。其中，SC_offset为子载波偏移指示信息，其范围为0-11。bitmap1_a和bitmap1_b分别指示了相邻的2个40ms时长中的bitmap2的周期扩展，从而指示了80ms周期中的保留资源。
如图14所示，终端设备为了确定SIB1-BR中第一资源块(一个第一资源块＝频域1NB*时域1子帧中的后X个符号)的样式：可以先通过bitmap3和SC_offset确定该第一资源块的频域位置，然后根据bitmap2确定其在1个slot中的时域位置，最后通过bitmap1_a和bitmap1_b，分别确定由bitmap3和bitmap2确定的第一资源块在一个80ms中的前40ms和后40ms的时频位置。由图13可以得到的是，在80ms周期中的后40ms中不存在第一资源块，可想而知后40ms的bitmap1_b为全0。其他需要保留的资源块的确定方法与第一资源块类似，在此不再一一赘述。
需要说明的是，本发明也可以为eMTC系统保留CRS、PSS、SSS、PBCH、SIB1-BR中的一种或多种所占的资源。例如，当NR系统仅为eMTC系统保留PSS、SSS、PBCH、SIB1-BR所占资源时，保留资源指示信息可以包括一个指示周期大于门限值的第一位图信息、子载波偏移指示信息、第二位图信息和第三位图信息，或者，包括一个指示周期大于门限值的第一位图信息、连续子载波指示信息和第二位图信息，或者，包括至少二个指示周期小于或等于门限值的第一位图信息，子载波偏移指示信息、第二位图信息和第三位图信息，或者，包括至少二个指示周期小于或等于门限值的第一位图信息、连续子载波指示信息和第二位图信息。在具体的实现中，保留资源指示信息需要包括的指示可以根据具体应用场景的需求进行配置，本申请实施例在此并不做具体限制。
本申请实施例提供的保留资源的指示方法，终端设备根据来自网络设备的包括一个指示周期大于门限值的第一位图信息，或至少二个指示周期小于或等于所述门限值的第一位图信息的保留资源指示信息，能够精确的确定出需要为通信系统保留的资源。
