在一种可能的实施方式中，
所述第三指示信息指示的第一装置期望用于数据传输的时频资源不包括第一初始BWP的频域资源和第二初始BWP的频域资源，即第一装置期望用于数据传输的资源与第一初始BWP资源之间不重叠，并且第一装置期望用于数据传输的资源与第二初始BWP资源之间也不重叠。

如果所述期望用于数据传输的时频资源的位置未发生改变，则不需要包括第五字段，依然采用最近一次第三字段指示的时频资源进行数据传输，从而避免重复发送相同时频资源位置的指示信息。
本实施方式中，只有在第一装置期望用于数据传输的时频资源的位置发生变化时，才发送第五字段，相比于不区分时频资源位置发生变化的指示方法，避免了重复发送相同时频资源位置的指示信息，从而节省了信令开销。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。在对本申请实施例的技术方案说明之前，首先结合附图对本申请实施例的应用场景进行说明。
本申请技术方案主要应用于未来行业私有网络与公共网络之间资源共享的场景，其中所述行业私有网络可以简称为“私网”，包括但不限于工业制造工厂、工业园区、生产园区等。所述公共网络可以简称为“公网”，例如长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统，或新无线(new radio，NR)通信系统，以及未来的移动通信系统等。其中，所述新无线也可称为新空口。
可选的，所述私网又称为专用网络，或简称为“专网”。
本申请的技术方案主要为协调分配给不同网络设备的公网与私网的频谱资源，从而达到各个设备对频谱资源的合理利用。其中，所述频谱资源包括5G NR通信系统中，信道和信号占用的频谱资源。为了便于后续方案理解，首先介绍相关背景技术，包括：5G NR物理信道和信号的名称、功能，以及5G NR的物理信道所在的时频资源位置和大小，部分带宽(Bandwidth Part，BWP)等。
表1为5G网络的下行物理信道/信号和功能对应表,表2为5G网络的上行物理信道/信号和功能对应表。所述物理信道按使用对象可分为公共信道和专用信道；按用途可分为控制信道和数据信道。进一步地，公共信道和控制信道可用于传输和接收所述数据信道，其中，所述公共信道包括：同步信号(Synchronization Signal，SS)、物理广播信道(Physical broadcast channel，PBCH)和物理随机接入信道(Physical Random Access Channel，PRACH)。所述控制信道包括物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理上行控制信道(Physical Uplink Control Channel，PUCCH)。所述数据信道包括物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。具体地，如下面的表1和表2所示。
表1，下行物理信道/信号和功能对应表

Figure PCTCN2019103385-appb-000008
表2，上行物理信道/信号和功能对应表
Figure PCTCN2019103385-appb-000009
图1为一种下行物理信道和信号的时频域分布的示意图。下行物理信道被划分出多块资源，具体地，被划分的资源包括PDCCH、PDSCH、SS/PBCH和CSI-RS等。其中，所述PDSCH可用于承载DMRS或PT-RS。
如图1所示，以子帧(subframe)0的一个下行时隙(slot)0为例，对于PDCCH资源，被配置为在时域上占用时隙0的前3个符号，即第0至第2个符号，其频域上使用的资源可配置。并且支持PDCCH和PDSCH资源在相同符号上频分复用(Frequency-division multiplexing，FDM)。
对于承载有DMRS的PDSCH资源(英文：DMRS for PDSCH)，在划分时该PDSCH资源的时域、频域位置，时频资源的大小均可配置；并且支持DMRS和PDSCH资源在相同符号上频分复用。
对于同步信号/物理广播信道(SS/PBCH，SSB)资源的划分，其时域位置一般是固定 的，频域位置可配置。例如，配置该SSB在频域上的起始位置为某个RE，但该SSB在频域上占用20个资源块(resource block，RB)；并且支持SSB和PDSCH资源在相同符号上频分复用。
对于CSI-RS资源的划分，其时域、频域位置以及带宽大小均可配置，并且支持CSI-RS和PDSCH相同符号上频分复用。
另外，在下行物理信道中还被划分出一块资源用于传输PT-RS，该用于传输PT-RS的资源在图1中未示出，具体地，该PT-RS资源的时域、频域位置以及带宽大小均可配置。可选的，将所述PT-RS资源配置在PDSCH资源内。
在下面的实施例中，在图1中示出的PDCCH、PDSCH、SSB和CSI-RS等资源被划分之后，这些资源的位置和大小将通过指示信息的方式通知给对端的接收设备。具体地，发送端配置所述指示信息的过程，以及所述指示信息中所携带的内容在后续的实施例中会详细介绍。对于这些被划分的资源，例如SSB资源，其时频位置以及大小可以统一地设置。
举例说明，图2为一种SSB资源的示意图。SSB可称为同步广播块(SS PBCH Block)，一个SSB在频域上占用20RB，时域上占用4个连续符号。具体地，一个SSB包括：主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)和PBCH。其中，在时域上的4个连续符号中，PSS位于第1个符号，SSS位于第3个符号，PBCH位于第2和第4个符号。
在5G NR中，每个SSB的频域位置可以灵活配置，用户设备(User equipment，UE)可通过盲检信道来获得所述SSB的频域位置；而SSB的时域位置也可以配置，例如通过协议来规定，不同子载波间隔(subcarrier carrier space，SCS)和SSB时域图案(pattern)之间的对应关系，通过SSB时域图案可确定SSB的时域位置。表3示出了一种SCS和SSB时域图案之间的对应关系。所述SSB时域图案反映出下行物理信道上所有SSB的时域符号的分布情况，对于各个时域图案可以由不同的方案(case)来表示。具体地，图3给出了方案A到方案E 5种不同的时域图案示意图。
表3，SCS和SSB时域图案之间的对应关系
Figure PCTCN2019103385-appb-000010
Figure PCTCN2019103385-appb-000011
例如，UE根据自己的NR工作频段以及表3所示对应关系，确定自己的SSB子载波间隔，以及SSB子载波间隔所对应的SSB时域图案，所述SSB时域图案为方案A至方案E中的一个，然后根据确定的方案得到每个SSB的时域位置。
需要说明的是，在n5的工作频段上(800M)可支持15KHz和30KHz两种SCS，当UE工作在n5频段时，需要分别使用15KHz和30KHz两种SCS做SSB信道盲检，并根据SSB信道盲检结果确定目标SCS。例如使用15kHz检测到SSB，则确定目标SCS为15kHz。然后根据表3所示的对应关系，UE确定出15kHz的SCS所对应的SSB时域图案是方案A，最后，UE根据方案A确定每个SSB的时域位置。
图3为方案A至方案E所对应的SSB图案定义及在时隙内位置分布的示意图。如图3所示，每个SSB图案在时域上占用4个连续的OFDM符号，不同方案对应的SSB图案在时域上的分布位置不同。例如，当使用方案A时，第一个SSB图案位于第一个时隙的第2至5OFDM符号，第二个SSB图案位于第一个时隙的第8至11OFDM符号。
需要说明的是，在子载波间隔是30KHz时，SSB图案包括方案B和方案C，在这种情况下，配置方案C是主用的SSB图案。
可选的，对于SSB的周期，可以通过系统消息块(System Information Block，SIB)来配置，例如网络设备通过SIB1来配置SSB的广播周期。进一步地，所述SSB的广播周期可以为5ms、10ms、20ms、40ms、80ms和160ms等。
另外，协议规定了SSB支持的最大块(block)的个数。例如对于Sub 3G，定义最大4个SSB；对于Sub 3G至Sub 6G，定义最大8个SSB；对于Sub 6G以上，定义最大64个SSB。当小区中实际发送的SSB个数小于协议中定义的最大SSB个数时，会有剩余SSB资源未被使用，为了使资源充分利用，基站可以指示在这些剩余的SSB资源上发送PDSCH资源。一种实现方式是，利用系统消息(system Information，SI)或无线资源控制(Radio Resource Control，RRC)信令来指示未被使用的SSB资源位置。
可以理解地，所述SSB的时域图案可通过NR工作频段和SCS取值来确定，进一步地，所述SCS取值可通过UE盲检信道确定。但对于本实施例，两端交互的设备是对等设备，例如基站与基站之间的交互，所以，各端基站彼此是不知道对端基站的NR工作频段和SCS 取值，为了实现对SSB资源的位置指示，一种具体的实现方式是，两端基站彼此交互各自的NR工作频段、SCS取值、SSB周期等。更进一步地，两端设备互相指示和确定SSB资源的过程将在后续的实施例中详细说明。
其中，在上述对SSB时域图案指示的过程中，涉及5G NR无线帧结构以及该无线帧(radio frame)所包含的子帧(subframe)数、时隙(slot)数、符号(symbol)之间的对应关系。表4给出了一种NR子载波配置、每时隙符号数、每子帧时隙数之间的对应关系，与LTE每个子帧包含的时隙个数固定不同，5G NR的每个子帧包含的时隙个数可变，且所述每个子帧包含的时隙个数与子载波间隔取值有关。
为了便于理解，图4给出当子载波间隔为30KHz时，5G NR网络无线帧结构示意图。如图4所示，一个无线帧长度T f＝10ms，T f表示一个无线帧的长度；每个无线帧由10个子帧组成，每个子帧长度T sf＝1ms，T sf表示一个子帧的长度；每个子帧包含两个时隙，即1subframe＝2slot；每个时隙由14个OFDM符号组成，即1slot＝14OFDM。

为40。
由于5G NR业务种类多样，不同的业务对频谱资源的需要也不同，所以引入部分带宽(Bandwidth part，BWP)概念。系统可以根据不同业务的需要来配置BWP。具体地，BWP按照种类可以划分为：初始(Initial)BWP、专用(Dedicated)BWP，激活(Active)BWP和默认(Default)BWP。
所述初始BWP是UE初始接入阶段使用的BWP，即初始接入阶段的信号和信道在该初始BWP内传输。所述专用BWP是UE在RRC连接态时使用的BWP。一般地，一个UE最多可以被配置4个专用BWP。所述激活BWP是UE在RRC连接态的某一时刻被激活的BWP，该激活BWP可以是多个专用BWP中的一个或多个。在现有标准R15协议版本中，UE在RRC连接态时，在某一时刻只配置一个激活BWP。所述默认BWP是UE在RRC连接态时，当UE的BWP不活跃定时器(inactivity timer)超时后该UE会从激活BWP回到默认的BWP上；该默认BWP可以是多个专用BWP中的一个。具体地，可以通过RRC信令指示UE选择某一个专用BWP来作为所述默认BWP。
对于BWP的频域位置指示，一种可能的实现方式是通过资源块(resource block,RB)索引指示。具体地，设置点A(point A)作为基本参考点。所述点A为资源组(Resource group，RG)所有RB的基本参考点，所述点A可以通过参考位置(Reference Location) 和偏移量(Offset)计算来获得。如图5所示，在频域上点A位置等于参考位置与偏移量之和，即表达式为：point A＝Reference Location+Offset。其中，所述参考位置是第一个SSB的起始位置，进一步地，所述SSB的起始位置可以是第一装置和第二装置在进行SSB交互时获得。进一步地，关于RB，RG参见TS 38.211中4.4章节。
可选的，所述offset的取值可以为正值，也可以为负值。
公共资源块(Common RB，CRB)可用于RG内RB的索引，且CRB的第0号子载波与点A对齐。物理资源块(Physical RB，PRB)可用于BWP内RB的索引，且在每个BWP内从0开始计数。一般地，PRB与CRB的资源配置参数(numerology)相同。其中，所述资源配置参数可包括以下至少一种：子载波间隔、时隙长度、循环前缀(Cyclic prefix，CP)。另外，对于不同资源配置参数，点A的位置一般都是固定的，不同资源配置参数的CRB的0号子载波位置也都相同，且与点A位置相同，但各自独立编号。
现有的LTE和NR频谱共享的方案，主要针对小区覆盖范围完全重叠或部分重叠的LTE小区和NR小区。如图6a和图6b所示，在LTE和NR频谱共享流程中，LTE小区的基站(eNB)和NR小区的基站(gNB)之间通过互发消息来通知各自期望使用的资源，例如eNB向gNB发送资源请求消息，该资源请求消息中包括eNB期望使用的资源，gNB接收后向eNB回复资源响应消息。该资源响应消息用于向所述eNB反馈，所述gNB收到所述eNB期望使用的资源情况。可选的，该资源响应消息还用于指示所述gNB期望使用的资源情况。
例如，所述资源请求消息为演进的通用陆地无线接入-新无线小区资源协调请求(E-UTRA-NR CELL RESOURCE COORDINATION REQUEST)；所述资源响应消息为演进的通用陆地无线接入-新无线小区资源协调响应(E-UTRA-NR CELL RESOURCE COORDINATION RESPONSE)。其中E-UTRA即为LTE，演进的通用陆地无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)。
表5示出LTE和NR资源共享与公网和私网的资源共享这两种资源共享的不同点。比如LTE和NR资源共享限制了使用场景，且未考虑私网(比如私网标识)、以及NR的一些特性(比如初始BWP和SSB资源)，所以现有的LTE和NR频谱共享的方案，不能直接用于公网和私网共享资源，需要设计新的频谱共享方案，从而实现公网和私网的频谱共享。

综上所述，当需要私网和公网业务共享频谱资源时，考虑未来频谱稀缺以及不同业务对频谱资源的需求不同，需要高效共享频谱资源，但现有频谱共享技术不适用于公网和私网的共享场景。鉴于此，本申请实施例提出一种资源共享的方法，通过第一装置和第二装置之间的信令交互、或者通过集中控制器来统一协调两个装置之间的频谱资源，从而实现第一装置和第二装置之间的高效地频谱资源共享。
下面对本实施例提供的资源共享方法做详细的说明。

本实施例提供一种资源共享的方法，该方法可应用于至少两个装置组成的通信系统，比如，系统包括第一装置和第二装置。进一步地，所述第一装置可以是一种网络设备，该网络设备包括基站(base station，BS)进一步地，所述基站可以是全球移动通信系统(global system for mobile communication，GSM)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-CDMA，WCDMA)中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional NodeB，eNB/e-NodeB)，或者下一代LTE中的演进型基站(next generation eNB，ng-eNB)，或者NR中的基站(gNB)，或者，未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
本申请实施例中，所述第二装置与所述第一装置是对等的设备，可以是与第一装置相同的网络设备。另外，在实现本发明方式的所涉及的步骤和工作原理上，所述第一装置和所述第二装置是对等的，即都要进行相同的处理。
本申请实施例中，所述第一装置可以是公网基站，也可以是私网基站。对应地，所述第二装置可以是公网基站或私网基站。例如，在一个场景下，第一装置是公网基站，第二装置是私网基站；在另一个场景下，第二装置是公网基站，第一装置是私网基站。
如图7所示，本申请实施例提供了一种资源共享的方法和装置，所述方法至少可以包括以下步骤：
步骤101：第一装置向第二装置发送第一指示信息。
所述第一指示信息用于指示所述第一装置保留的资源。例如，保留的资源用于传输PSS、SSS、PBCH、Common PDCCH和PRACH等重要信号。由于用于传输上述重要信号的资源不与第二装置共享，所以第一装置要预先预留该保留的资源，并将该保留的资源通知第二装置。
在一个示例中，所述第一指示信息用于指示第一初始部分带宽BWP的频域资源，所述第一初始BWP的频域资源为所述第一装置不与所述第二装置共享的资源，所述第一初始BWP的频域资源为所述第一装置和所述第二装置的第一候选共享资源的一部分。所述第一候选共享资源为第一装置和第二装置所能够使用的公共资源或公共带宽。
在一种可能的设计中，所述第一初始BWP资源中包含所述第一装置保留的资源。当第一初始BWP资源被保留时，其包含的所述第一装置保留的资源也被保留，因此通过指示第一初始BWP的资源来达到指示保留所述第一装置的保留资源的目的。进一步地，在指示第 一初始BWP的资源过程中，一般地，对于初始BWP的时域位置可灵活配置，例如为整个时域资源，所以本实施例中通过第一指示信息来指示第一初始BWP的频域位置即可。
比如，在NR系统中，初始BWP资源中包括：PSS、SSS、PBCH(即SSB)以及公共(Common)PDCCH、PRACH等保留资源，所以可以利用初始BWP来统一指示这些保留资源的频域位置。参见图8，所述第一装置保留的资源还包括：第一装置用于发送系统消息SI和寻呼(paging)消息的资源，且这些资源可以在Common PDCCH资源上。
步骤102：第一装置从第二装置接收第二指示信息。
所述第二指示信息用于指示所述第二装置保留的资源。对于保留的资源的描述，参见步骤101。第二装置要预先预留第二装置保留的资源，并将该保留的资源通知第一装置。
在一个示例中，所述第二指示信息用于指示第二初始BWP的频域资源，所述第二初始BWP的频域资源为所述第二装置不与所述第一装置共享的资源，所述第二初始BWP的频域资源为所述第一候选共享资源的一部分。在一种可能的设计中，所述第二初始BWP资源中包含所述第二装置保留的资源。
可选的，在第二指示信息来指示第二初始BWP的频域资源时，一种可能的情况是，第一初始BWP的频域资源与第二初始BWP的频域资源之间不重叠，即第一装置指示的第一初始BWP的频域资源和第二装置指示的第二初始BWP的频域资源之间在所述第一候选共享资源中没有重叠的频谱资源。
在一个示例中，所述第一指示信息和所述第二指示信息又称为保留资源的指示信息。
步骤103：第一装置向第二装置发送第三指示信息，所述第三指示信息用于指示所述第一装置在所述第一候选共享资源中期望用于数据传输的时频资源。
例如，所述第一候选共享资源为第一装置的可用资源和第二装置的可用资源的交集，可选的，第一候选共享资源可以是第一装置的全带宽、或者是第二装置的全带宽、或者第一装置和第二装置的公共带宽。如图9a所示，第一装置的可用资源是0～100兆赫兹(MHz)，第二装置的可用资源是20～120MHz，第一装置和第二装置的第一候选共享资源为20～100MHz。并且，如图9b所示，在该第一候选共享资源20～100MHz中，所述第一指示信息所指示的第一初始BWP的频域资源是20～30MHz，该第一初始BWP的频域资源为所述第一候选共享资源的一部分。所述第二指示信息所指示的第二初始BWP的频域资源是80～90MHz，也属于所述第一候选共享资源的一部分。
所述第三指示信息指示的时频资源可以是该第一候选共享资源中除去第一初始BWP的频域资源后的剩余资源中的一部分或全部；或者，第三指示信息指示的时频资源还可以是该第一候选共享资源中除去所述第一初始BWP的频域资源以及所述第二初始BWP的频域资源之后，剩余资源中的一部分或全部。
可选的，所述第三指示信息指示的第一装置期望用于数据传输的时频资源，不包括所述第一初始BWP的频域资源和所述第二初始BWP的频域资源。
第二装置接收到第三指示信息后，根据所述第三指示信息指示的第一装置期望用于数据传输的时频资源，以及第一装置的第一保留资源来计算第一装置的资源分配情况。当最近一次收到的第三指示信息指示的内容和最近一次收到的第一保留资源存在冲突时，第二装置会优先考虑第一保留资源。第三指示信息指示的内容和最近一次收到的第一保留资源存在冲突意味着，第三指示信息指示的期望用于数据传输的时频资 源和所述第一保留资源之间存在重叠。在这种情况下，第二装置优先考虑第一保留资源是指，在计算第一装置的资源分配时，第二装置会以最近一次收到保留资源指示为准。
例如，如果第二装置最近一次收到的第一装置期望用于数据传输的时频资源为20～60MHz，而最近一次收到的第一装置的保留资源为20～30MHz，那么第二装置在计算第一装置的资源分配时，会认为第一装置的保留资源为20～30MHz，而第一装置期望用于数据传输的时频资源为30～60MHz。
步骤103具体包括以下实现方式：
第一种实现方式是，所述第三指示信息指示第一装置期望用于数据传输的频域资源为：所述第一候选共享资源中除去所述第一初始BWP所指示的频域资源20～30MHz，和第二初始BWP所指示的频域资源80～90MHz之后的剩余资源，所述剩余资源包括30～80MHz，以及90～100MHz，如图9b所示。可选的，所述第一装置期望用于数据传输的频域资源还可以是所述剩余资源中的一部分。例如30～50MHz或者90～100MHz。
第二种实现方式是，所述第一装置期望用于数据传输的频域资源还可以是，所述第一候选共享资源中除去所述第一初始BWP所指示的频域资源后剩余的资源，例如，在20～100MHz中除去所述第一指示信息所指示的频域资源20～30MHz之后的资源，即为30～100MHz，或者还可以是该剩余资源中的一部分，例如30～50MHz。
第三种实现方式是，所述第一装置期望用于数据传输的频域资源还可以是在所述第一候选共享资源中的资源的全部或一部分，例如，在20～100MHz中的资源，或者还可以是20～100MHz中的一部分，例如，30～60MHz。
在上述实施方式中，所述第一装置期望用于数据传输的频域资源可以是频域连续的、或者是频域不连续的，这里不做限制。
此外，在上述步骤101至步骤103之后方法还包括：
步骤104：第一装置从第二装置接收第四指示信息，所述第四指示信息用于指示所述第二装置在所述第一候选共享资源中期望用于数据传输的时频资源。
其中，所述第二装置期望用于数据传输的时频资源，与，所述第一装置期望用于数据传输的时频资源之间，可以存在重叠资源，也可以不存在重叠资源。
所述第四指示信息所指示的时频资源可以是：所述第一候选共享资源中除去所述第二初始BWP的频域资源后的剩余资源中的一部分或全部；或者，还可以是所述第一候选共享资源中除去所述第一初始BWP的频域资源，以及除去所述第二初始BWP的频域资源之后剩余资源中的一部分或全部；或者，还可以是所述第一候选共享资源中除去第一初始BWP、第二初始BWP的频域资源，以及所述第三指示信息指示的资源之后，剩余资源中的一部分或全部。
在一个示例中，第二装置确定其期望用于数据传输的频域资源为：第一候选共享资源20～100MHz中除去所述第一初始BWP的频域资源20～30MHz，和第二初始BWP所指示的频域资源80～90MHz之后的剩余资源，所述剩余资源包括30～80MHz，以及90～100MHz。
在一个示例中，第二装置确定其期望用于数据传输的频域资源为：第一候选共享资源20～100MHz中进行资源指示。
在一个示例中，在第一装置期望用于数据传输的频域资源与第二装置期望用于数据传 输的频域资源之间不重叠的情况下，第二装置确定所述第四指示信息的过程，如图9c所示，第一初始BWP的频域资源为20～30MHz，第二初始BWP的频域资源为80～90MHz，第一装置期望用于数据传输的频域资源为30～80MHz，则第二装置确定其期望用于数据传输的频域资源为90～100MHz。即在所述第一候选共享资源20～100MHz中除去20～30MHz、80～90MHz以及30～80MHz之后剩余的资源。
在一个示例中，在第一装置期望用于数据传输的频域资源与第二装置期望用于数据传输的频域资源之间，存在重叠资源的情况下，第二装置确定所述第四指示信息的过程，如图9d所示，第一初始BWP的频域资源为20～30MHz，第二初始BWP的频域资源为80～90MHz，第一装置期望用于数据传输的频域资源为30～80MHz，第二装置发现自己期望用于数据传输的资源与第一装置期望用于数据传输的资源之间存在重叠，比如所述重叠的资源为40～80MHz，则为了避免冲突，第二装置可以指示自己期望占用该重叠资源的一部分，比如50％，本示例中，假设第二装置期望占用所述重叠资源40～80MHz中的60～80MHz，然后再加上未与第一装置有重叠的资源90～100MHz，得到第四指示信息中第二资源期望用于数据传输的频域资源为60～80MHz以及90～100MHz。
需要说明的是，在本示例中，对于期望资源中重叠部分的占用情况，第二装置可以根据当前业务需求来确定期望占用所述重叠资源的大小，或者还可以通过其他条件来确定，本实施例对此不做具体限制。
另外，需要说明的是，本实施例中，不对上述步骤101和102之间的执行顺序进行限定，并且也不对步骤103和104之间的执行顺序进行限定。
例如，在首先执行上述步骤102，然后执行步骤101的情况下，即第一装置先接收第二装置发送的第二指示信息，然后再配置第一指示信息，该第一指示信息所指示的第一初始BWP的频域资源与第二指示信息所指示的第二初始BWP的频域资源不重叠，最后将所述第一指示信息发送给第二装置。
应理解，第一装置在执行完上述步骤101和102后，可以先执行步骤104，然后再执行步骤103，第一装置可以第一初始BWP的频域资源和第二指示信息指示的第二初始BWP的频域资源，以及所述第四指示信息，确定第一装置期望用于数据传输的资源，并将该资源通过第三指示信息发送给第二装置。
在一示例中，如图9e所示，第一初始BWP的频域资源为20～30MHz，第二指示信息指示的第二初始BWP的频域资源为80～90MHz，第四指示信息指示的第二装置期望用于数据传输的频域资源为55～80MHz和90～100MHz。第一装置确定其期望用于数据传输的频域资源为30～55MHz。具体地，所述30～55MHz为在第一候选共享资源20～100MHz中除去20～30MHz，80～90MHz，以及所述第四指示信息中的部分资源55～80MHz和90～100MHz之后的剩余资源。其中，所述部分资源中的55～80MHz可以根据第一装置或第二装置的业务需求确定，本示例对此不予限定。
本申请实施例中，所述第三指示信息所指示的资源，是第一装置根据自身业务对共享资源的需求来确定。所述第四指示信息所指示的资源，是第二装置根据自身业务对共享资源的需求来确定，本申请实施例对第一装置确定第三指示信息的具体过程，以及第二装置确定第四指示信息的具体过程不予限定。
在本申请实施例方式中，第一装置和第二装置利用第一指示信息和第二指示信息来统 一指示初始BWP的资源位置，由于该初始BWP频域资源中包括至少一种保留的资源，所以通过初始BWP来统一指示保留资源的方式，相比于在指示信息中携带每种资源的具体位置和大小的方式，简单、易于实现，并且节省信令交互的开销。
另外，通过第三指示信息和第四指示信息来分别指示第一装置和第二装置期望用于数据传输的时频资源，使得这两个装置互相获知对方期望使用的资源，从而为合理分配这两个装置的实际共享资源提供依据，本方法通过两端装置实时地交互指示信令，实现了第一装置和第二装置之间频谱资源的高效共享。
可选的，在上述步骤101至步骤104之后，方法还包括：
步骤105：第一装置确定在所述第一候选共享资源中的共享资源。该共享资源是第一装置实际共享的资源。
所述共享资源为第一装置基于所述第一初始BWP和自己期望用于数据传输的资源，以及所述第二初始BWP和第二装置期望用于数据传输的资源中的至少一种，在所述第一候选共享资源中确定的一部分或者全部实际可用于传输的资源。
一种可能的实现方式是，第一装置根据所述第一初始BWP，第二初始BWP和所述第二装置期望用于数据传输的时频资源，确定第一装置在所述第一候选共享资源中的共享资源。
如图10a所示，第一初始BWP的频域资源为20～30MHz，第二初始BWP的频域资源为80～90MHz，所述第四指示信息指示的第二装置期望用于数据传输的频域资源为60～80MHz和90～100MHz，则在第一候选共享资源中确定第一装置的共享频域资源为30～60MHz。即所述第一候选共享资源20～100MHz中，除去20～30MHz、80～90MHz，以及60～80MHz和90～100MHz之后的剩余频域资源。
一种可能的实现方式是，第一装置根据所述第一初始BWP、第二初始BWP、第一装置期望用于数据传输的资源，和第二装置期望用于数据传输的资源，确定第一装置在所述第一候选共享资源中的共享资源。
如图10b所示，第一初始BWP的频域资源为20～30MHz，第二初始BWP的频域资源为80～90MHz，第一装置期望用于数据传输的频域资源为30～80MHz，第四指示信息指示的第二装置期望用于数据传输的频域资源为55～80MHz和90～100MHz。此时，第一装置和第二装置各自期望用于数据传输的资源之间存在重叠资源，该重叠资源为55～80MHz，对于这部分重叠资源，第一装置可根据业务需求，占用其中的一部分，比如占用55～70MHz，然后再加上未重叠的30～55MHz，最后确定第一装置在第一候选共享资源中的共享频域资源为30～70MHz。
对应地，所述方法还包括：第二装置根据第一装置发送的所述第一指示信息、所述第三指示信息，以及所述第二初始BWP和第二装置期望用于数据传输的时频资源中的至少一种，确定第二装置在所述第一候选共享资源中的共享资源。该确定的共享资源为第二装置实际共享的资源。具体的确定过程参见步骤105中第一装置确定所述第一候选共享资源中的共享资源的描述，此处不再赘述。
本实施例，针对第一装置和第二装置的共享资源提出一种频谱资源共享的方法，通过设计第一装置和第二装置之间的交互流程和交互信息，例如在指示信息中包括初始BWP或SSB资源位置信息，或者包括第一装置和第二装置各自期望用于数据传输的资源，使得第 一装置和第二装置互相获知对方期望使用的资源，从而实现这两个装置之间频谱的高效共享。
下面对本申请实施例中的第一指示信息、第二指示信息、第三指示信息和第四指示信息中所携带的内容，以及具体的指示方式进行详细说明。
在上述步骤101中，所述第一指示信息在用于指示第一初始BWP的频域资源时，具体包括：第一指示信息用于指示第一初始BWP的频域起始位置、第一初始BWP的频域终止位置和第一初始BWP的频域宽度中的至少一种。
在上述步骤102中，所述第二指示信息在用于指示第二初始BWP的频域资源时，具体包括：第二指示信息用于指示第二初始BWP的频域起始位置、第二初始BWP的频域终止位置和第二初始BWP的频域宽度中的至少一种。
以步骤101中第一装置发送的所述第一指示信息为例，第二装置根据所述第一装置发送的所述第一指示信息确定所述第一初始BWP的频域资源的过程，具体包括：
一种实现方式是，在所述第一指示信息中只包含上述三种参数中的一种时，所述第二装置根据当前第一指示信息中携带的一种参数，以及通过其他方式获取的另外至少一种参数来确定所述第一初始BWP的频域资源。具体地，第二装置通过第一指示信息获取所述第一初始BWP的频域起始位置，然后根据所述第一装置发送或者其他辅助参数计算确定出第一初始BWP的频域终止位置和频域宽度中的至少一种，最后确定出第一初始BWP的频域资源。例如，第一指示信息中指示第一初始BWP的频域起始位置为2600MHz，然后第二装置根据与第一装置约定的频域宽度，比如400MHz，最后确定出第一初始BWP的频域资源为2600～3000MHz。
另一种实现方式是，所述第一指示信息中包含上述两种或三种参数时，所述第二装置根据该第一指示信息所携带的任意两种参数来确定所述第一初始BWP的频域资源。具体地，所述第一指示信息包括第一初始BWP的频域起始位置和频域宽度两种参数时，确定第一初始BWP的频域终止位置等于所述第一初始BWP的频域起始位置加上所述频域宽度，进而可以确定所述第一初始BWP的频域资源为从第一初始BWP的频域起始位置到频域终止位置之间的范围。例如，第二装置接收的所述第一指示信息中指示第一初始BWP的频域起始位置为2600MHz，频域终止位置为3000MHz，则第二装置可以确定所述第一装置指示的第一初始BWP的频域资源范围为2600～3000MHz。
在上述第一指示信息所包含的内容中，所述第一初始BWP的频域起始位置，或，第二初始BWP的频域起始位置可以通过绝对频点来指示，例如，绝对频点为2600MHz。或者，还可以通过索引(index)标识的方式指示，例如，采用协议预定标识，如子载波索引(subcarrier index)，资源块索引(RB index)等。
举例说明，在第一初始BWP的频域起始位置与一RB索引标识所对应的位置相同时，配置所述第一指示信息中携带该RB索引标识。例如当所述第一指示信息中携带RB索引为10的指示信息时，第二装置根据该RB索引10，以及预存的RB索引标识与初始BWP起始位置之间的对应关系，RB索引10对应的频点为2700MHz，因此确定所述第一初始BWP起始位置为2700MHz。
可以理解地，对于第一、第二初始BWP的频域终止位置也可以通过绝对频点来指示，例如所述绝对频点为2620MHz。或者通过初始BWP的频域起始位置加上所述频域带宽来确 定所述频域终止位置。进一步地，所述频域带宽可以通过RB个数和占用频域资源的绝对数值来确定，例如第一指示信息指示所述频域带宽共占用5个RB，每个RB占用的频域资源为固定值，如180KHz，则确定频域宽度为5×180KHz＝900kHz。
本实施例中，通过在第一指示信息中携带第一初始BWP的频域起始位置、频域终止位置和频域宽度中的至少一种来指示第一初始BWP的频域资源，从而达到指示效率高、开销小的有益效果。
进一步地，在指示所述第一初始BWP的频域位置时，还可以通过辅助参数来间接指示出第一初始BWP的频域位置。具体地，所述第一初始BWP的频域起始位置根据如下方式一或者方式二确定。
方式一：根据第一下行带宽起始位置，和所述第一下行带宽的频域起始位置与所述第一初始BWP的频域起始位置之间的偏移量确定。例如，如图11a所示，设所述第一下行带宽起始位置为A点(point A)，所述第一下行带宽的频域起始位置与所述初始BWP的频域起始位置之间的偏移量为，所述A点到第一初始BWP的频域起始位置之间的偏移量(offset)，则所述第一初始BWP的频域起始位置为A点位置加上所述offset后的位置。
即，第一初始BWP的频域起始位置＝A点+offset。
方式二：根据同步广播块SSB的频域起始位置、所述SSB的频域起始位置与第一下行带宽的频域起始位置之间的偏移量、以及所述第一下行带宽的频域起始位置与所述第一初始BWP的频域起始位置之间的偏移量确定。例如，如图11b所示，设所述SSB的频域起始位置为参考位置(Reference Location)且所述SSB的频域起始位置与第一下行带宽的频域起始位置之间的偏移量为offset 1，所述第一下行带宽的频域起始位置与所述第一初始BWP的频域起始位置之间的偏移量为offset 2，则所述第一初始BWP的频域起始位置为A点位置加上offset 1和offset 2后的位置。
即，第一初始BWP的频域起始位置＝参考位置-offset 1+offset 2。
需要说明的是，offset，offset 1，offset 2中每个的取值可以是正数，也可以是负数。参考点位置point A或Reference Location可以是协议规定的、或者是通过两个装置间的信令通知对方。所述第一下行带宽为所述第一装置对应的系统带宽。
另外，所述第二初始BWP的频域起始位置根据如下方式三或者方式四确定，
方式三：根据第二下行带宽的频域起始位置，和所述第二下行带宽的频域起始位置与所述第二初始BWP的频域起始位置之间的偏移量确定；
方式四：根据SSB的频域起始位置、所述SSB的频域起始位置与第二下行带宽的频域起始位置之间的偏移量、以及所述第二下行带宽的频域起始位置与所述第二初始BWP的频域起始位置之间的偏移量确定。
具体地，方式三和方式四的确定过程与前述方式一和方式二相同，本实施例此处不再赘述。所述第二下行带宽为所述第二装置对应的系统带宽。
应理解，在步骤102中，第二装置确定第二初始BWP的频域起始位置的方法，与前述第一初始BWP的频域起始位置确定方法类似，本实施例对此不再赘述。
在一个示例中，所述初始BWP的频域宽带可以通过与位置和带宽(location And Bandwidth)对应的资源指示值(Resource indication value，RIV)，以及如下公式来确定，
公式1：

第一装置(或第二装置)同样可以通过查表获得。
在本实施例的步骤102中，第二装置发送所述第二指示信息包括：第二装置发送第一响应消息，所述第一响应消息中包括所述第二指示信息。另外，该第一响应消息中还可以包括第二装置的属性标识，所述第二装置的属性标识用于指示第二装置是公网设备或私网设备。
需要说明的是，本实施例中上述描述了通过第一指示信息和第二指示信息来指示第一装置和第二装置的初始BWP的频域资源。此外，还包括初始BWP的时域资源，对于各方装置的初始BWP的时域位置可通过独立的消息来指示，或者还可以两端装置预先定义。例如，所述初始BWP的时域位置为整个所述第一候选共享资源的时域资源，还可以根据业务需求灵活配置，本申请实施例对初始BWP的时域位置，以及配置过程不予限制。
下面对上述步骤103中的第三指示信息和步骤104中的第四指示信息的配置过程进行说明。
在上述步骤103中，所述第三指示信息包括第一字段和第二字段，通过两级信息来指示。具体地，所述第一字段用于指示所述第一装置期望用于数据传输的时频资源的资源类型，所述资源类型包括上行(Uplink，UL)、辅助上行(Supplementary Uplink，SUL)和下行(Downlink，DL)资源类型中的至少一种；所述第二字段用于指示每种所述资源类型对应的时频资源位置。其中，SUL资源为低频资源，小于6GHz；UL资源为高频资源，大于 等于6GHz。
在一种实现方式中，第一装置通过第一字段指示其期望用于数据传输的资源包括UL共享、SUL共享、UL和SUL共享、DL共享资源中的一个；然后再通过第二字段指示每种共享资源的具体位置，是高频还是低频资源，比如第二装置在接收到所述第三指示信息后，根据该第三指示信息中的第一字段确定第一装置期望用于数据传输的资源，比如包括UL共享资源，然后通过第二字段指示该UL共享资源的频率范围，是SUL的低频资源还是UL的高频资源。
可选的，以第一字段来指示期望用于数据传输的资源可以称为一级指示，以第二字段来指示的资源可以称为二级指示。
在另一种实现方式中，所述第三指示信息还包括第三字段，所述第三字段用于指示所述第二字段中的期望用于数据传输的时频资源的生效时刻。所述期望用于数据传输的时频资源的生效时刻是指，第二装置在接收到所述生效时刻指示时，认为从所述生效时刻指示的时刻开始，第一装置指示的期望用于数据传输的时频资源有效。
可选的，所述生效时刻指示精度可以是系统帧号(System Frame Number，SFN)、子帧号subframe、时隙号slot、符号symbol。如果所述生效时刻指示精度是系统帧号，则相当于在所述系统帧号指示的时刻开始，第一装置指示的期望用于数据传输的时频资源有效。同样的，如果所述生效时刻指示精度是子帧号，则所述生效时刻指示包括系统帧号指示和子帧号指示，所述子帧号用于指示生效时刻是所述系统帧中的哪个子帧，当第二装置接收到所述生效时刻指示时，认为在所述系统帧号指示和所述子帧号指示对应的时刻开始，第一装置指示的期望用于数据传输的时频资源有效。如果所述生效时刻指示精度是时隙号，则所述生效时刻指示包括：系统帧号指示、子帧号指示和时隙号指示，所述子帧号用于指示生效时刻是所述系统帧中的哪个子帧，比如第一子帧；所述时隙号用于指示生效时刻是所述第一子帧中的哪个时隙，比如第一时隙。
需要说明的是，在某一时刻，如果第一装置期望使用的传输资源发生变化时，则上述方法还包括：第一装置指示其发生变化的传输资源的步骤。具体地，包括：第一装置在所述第二字段中添加第四字段，所述第四字段用于指示每种所述资源类型对应的时频资源位置是否发生改变。
例如，用于数据传输的资源类型由UL变为DL，则第一装置在发送的第二字段中新增加第四字段，该第四字段指示本次传输的资源类型与前一次不同，并且在指示所述位置发生改变的情况下，所述第二字段还包括第五字段，所述第五字段用于指示改变后的期望用于传输数据的时频资源位置。例如，所述第五字段用于指示传输资源变为DL后具体的时频资源位置。
在所述第一装置指示其发生变化的传输资源时，所述第一装置还可以直接在所述第二字段中添加第五字段，并发送该第五字段，所述第五字段直接指示改变后第一装置期望用于传输数据的时频资源位置。
进一步地，所述第三指示信息可以通过以下任意一种方式指示：
方式一：位图(bitmap)指示
一种实现方式中，第三指示信息包括第二字段，该第二字段由二进制的字符串组成，其中每个字符占1比特(bit)空间，对应一个时频块，所述时频块在频域上可以表示一 个PRB，在时域上可以表示一个子帧(subframe)、或一个时隙(slot)、或一个符号(symbol)。具体地，比特值为“1”的字符位置所对应的资源为第一装置期望用于数据传输的资源，比特值为“0”的字符位置所对应的资源为第一装置不期望用于数据传输的资源。
例如图12a所示，第二字段为“00111100111100”表示一个时隙(14个符号)的时频资源，对应从时频块1到时频块14，其中时频块3到6，以及时频块9到12上所对应的比特值为“1”，表示这些时频块为第一装置期望用于数据传输的资源。剩余所有比特值为“0”的时频块，包括时频块1,2,7,8,13和14为第一装置不期望用于数据传输的资源。
另一种实现方式中，第三指示信息可以通过两种位图来指示，一种位图用于指示频域资源，另一种位图用于指示时域资源。具体地，在一种示例中，用RB级位图来指示频域资源，其中每个RB用一个比特表示，比特值为“1”表示该RB是用于数据传输的RB，比特值为“0”表示该RB不是用于数据传输的RB。用符号级位图来指示时域资源，其中每个符号(比如OFDM符号)用一个比特表示，比特值为“1”表示该符号用于数据传输，比特值为“0”表示该符号不用于数据传输。
例如图12b所示，在频域上，RB级位图为“0011100”表示只有中间的3个RB用于数据传输。在时域上，符号级位图为“00111100111100”表示只有第2至5，和第8至11个OFDM符号用于数据传输，其余的符号不用于数据传输。
可选的，第一装置将所述第三指示信息通过请求消息方式发送给第二装置，所述请求消息可以是基站间接口Xn消息，例如Xn建立请求(Xn Setup Resquest)或Xn配置更新(Xn Configuration Update)消息，具体是哪条Xn消息，这里不做限制。
方式二：多级指示
多级指示为通过两级或两级以上的指示信息来指示所述期望用于数据传输的资源。具体地，以两级指示为例，第一级指示用于指示第一装置期望用于数据传输的资源的频域位置，所述资源的频域位置组成频域图案，例如PRB pattern；第二级指示用于指示在一个时间周期内的每个时间单位是否采用第一级指示中的频域图案。可选的，所述第一级指示通过第一字段的方式指示，所述第二级指示通过第二字段的方式指示。其中，所述第一字段和所述第二字段均为二进制的字符串。
例如图13所示，在一个时间周期中，第一字段用于指示一种PRB pattern，该PRB pattern中包括PRB1至PRB n共n个PRB，对应n个比特，其中，比特值为“1”表示该PRB用于进行数据传输；比特值为“0”表示该PRB不用于进行数据传输。比如字符串“0110”表示PRB2和PRB3为用于数据传输的PRB，在PRB1和PRB4不用于数据传输。第二字段用于指示是否采用第一字段指示的PRB pattern；具体地，比如在时域符号(symbol)11所对应的比特值为“1”时，指示在第11个符号上使用上述PRB pattern，即在第11个符号上PRB2和PRB3用来进行数据传输，当symbol 11所对应的比特值为“0”时，指示在第11个符号上不使用上述PRB pattern，即在第11个符号上PRB2和PRB3不用来进行数据传输。
需要说明的是，所述一个时间周期内的时长包括但不限于一个子帧，时间周期可以配置，此外，时间周期内的每个时间单位还可以是其它时间粒度，比如时隙或OFDM符号，本实施例对此不予限制。
方式三：百分比指示。
所述百分比指示，可以理解为第一装置或第二装置的期望用于数据传输的资源通过百分数方式表示该期望的资源占可分配资源的百分比。其中，所述可分配资源为第一候选共享资源中除去所述第一初始BWP和所述第二初始BWP的频域资源之后剩余的资源。可选的，所述第一初始BWP和所述第二初始BWP的频域资源互相不重叠。
例如在频域上，通过百分比来指示第一装置期望用于数据传输的频域资源范围占所述可分配资源的百分比，例如50％，表示第一装置期望占用所述可分配资源的50％频域资源用于传输数据，然后再通过其他指示信息来指示期望的50％频域范围的起始位置或终止位置等。
另外，所述第三指示信息中还包括时域位置的指示信息，具体地，第一装置可以在所述可分配的资源中指示一个百分比，表示在所述50％频域范围内期望的使用的时域资源范围，例如80％，并且还包括具体的时域起始位置、终止位置和符号个数等。比如在一个时隙的14个OFDM符号中，指示从第2至10个OFDM符号为第一装置期望用于数据传输的时域资源，然后再根据频域指示的百分比(50％)以及频域起始位置、终止位置等信息可以唯一确定出所述第一装置期望用于数据传输的资源。
本实施提供的方法，利用各种方式，包括上述方式一至方式三，灵活地指示第一装置期望用于数据传输的资源，从而可以满足不同的需求。比如采用方式一或方式二来指示可以精确指示具体的资源位置；采用方式三的百分比指示则可以节约信令开销，因为只携带期望使用资源的百分比，其他信息可以通过预先配置或约定获得，所以相比于多级传输的精确指示方式，节约了信令的开销。
在上述实施例中，第一装置发送所述第一指示信息(步骤101)和发送所述第三指示(步骤103)可以通过以下两种方式实现。
一种实现方式，第一装置分别发送所述第一指示信息和所述第三指示信息。所述第一装置先将第一指示信息通过第一请求消息发送给第二装置(步骤101)，然后再将所述第三指示信息通过第二请求消息发送给第二装置(步骤103)。
另一种实现方式，第一装置将第一指示信息和第三指示信息通过一个消息来携带并发送给第二装置，具体地，图7所示的方法流程可以演变为图14所示的方法流程，具体包括：
步骤201：第一装置向第二装置发送第一请求消息，所述第一请求消息中包括所述第一指示信息和所述第三指示信息。
具体地，所述第一指示信息和所述第三指示信息的内容和配置方式与前述实施例的方法步骤101和步骤103相同，此处不再赘述。
在一种可选的实现中，在步骤201之前或之后，方法还包括：第二装置向第一装置发送所述第二指示信息，所述第二指示信息用于指示所述第二装置保留的资源，进一步地，所述第二装置保留的资源用第二初始BWP的频域资源来指示，所述第二初始BWP的频域资源为所述第二装置不与所述第一装置共享的资源，所述第二初始BWP的频域资源为所述第一候选共享资源的一部分。进一步地，所述第二指示信息可以通过第一响应消息发送，即所述第一响应消息中包括所述第二指示信息。
步骤202：第二装置接收来自所述第一装置的所述第一请求消息，根据所述第一请求消息中的第一指示信息和第三指示信息确定第四指示信息。其中，所述第四指示信息用于 指示所述第二装置期望用于数据传输的资源，且该资源与所述第一初始BWP的频域资源和所述第二初始BWP的频域资源之间不重叠。
步骤203：第二装置向所述第一装置发送第二响应消息，所述第二响应消息中包括所述第四指示信息。
具体地，所述第一指示信息至第四指示信息的内容和作用与前述实施例的步骤101至步骤104相同，参见上述关于各个指示信息的详细介绍，以及第一装置确定期望用于数据传输的资源和共享资源的过程，此处不再赘述。
本实现方式中，第一装置将第一指示信息和第三指示信息通过同一请求消息发送给第二装置，相比于分别发送这两个指示信息，节省了信令开销，另外，还能更真实地反应各端装置的业务对共享资源的需求。
此外，上述实施例中，所述方法还包括：第一装置发送第一装置的属性标识，所述属性标识用于指示该装置是公网设备还是私网设备(设备属性)。具体地，所述第一装置的属性标识可以为小区标识(cell ID)。
进一步地，如果第一装置是公网设备，则所述小区标识为第一装置的公网小区标识(cell ID)列表，该公网cell ID列表中包括至少一个公网cell ID，每个所述公网cell ID可以是E-UTRAN cell Identity(LTE小区的ID)，或者是NR Cell Identity(NR小区的ID)。其中，E-UTRAN Cell Identiy长度为28比特(bit)；NR Cell Identity的长度为36bit。
如果第一装置为私网设备，则所述小区标识为第一装置的私网小区标识列表，该私网cell ID列表中包括至少一个私网cell ID，例如该私网cell ID为闭合接入组(Closed Access Group，CAG)ID，或者为非公共网络(Non Public Network，NPN)ID，或者还可以是私网cell标识的比特数或设计方式等。其中，所述NPN ID可以由公用陆地移动网(Public Land Mobile Network，PLMN)和非公共网络指示(non-public network indicator，NID)来表示，所述PLMN由移动国家代码(Mobile Country Code，MCC)和移动网络代码(Mobile Network Code，MNC)组成。进一步地，在标识私网cell ID时，MCC取值为999。
进一步地，在步骤201中，第一装置发送的所述第一请求消息中还包括所述第一装置的属性标识，使得第一装置将所述第一指示信息和第一装置的属性标识一同发送给第二装置。可以理解地，所述第二请求消息中也可以包括所述第一装置的属性标识。
可选的，所述第二装置发送给所述第一装置的第一响应消息中还包括第二装置的属性标识，并且所述第二设备是公网设备或者私网设备的情况下，对应的cell ID与前述第一装置的cell ID属性情况相同，本实施例对此不详细介绍。
另外，本申请实施例中，图7或图14所示的消息交互流程中，各个指示信息或请求消息(包括响应消息)可以是Xn消息，其中Xn为NR基站间接口，所述第一请求消息可以是Xn消息，如Xn Setup Request，或Xn Configuration Update消息；所述第一响应消息可以是Xn建立响应(Xn Setup Response)消息，或Xn配置更新确认(Xn Configuration Update Acknowledge)消息等。

本实施例提供的方法，通过第三装置来集中管理和分配第一装置和第二装置之间的频谱资源，便于运营商集中管理、收费，从而可引导运营商通过频谱共享，增加盈利。
在本申请的一种可能的实现中，针对上述实施例一和实施例二中的所述第一指示信息和第二指示信息，以上述实施例中的第一指示信息为例，在所述第一指示信息用于指示所述第一装置保留的资源，例如SSB资源时，可以通过以下方式实现。
一种具体的实现方式是，利用第一指示信息分别指示SSB资源的时域位置和频域位置。其中，在用于指示SSB资源的时域位置时，一种指示方式是，利用图案索引(pattern index)的方式指示，比如，所述第一指示信息中包括pattern index A至pattern index E中的任意一个，每个pattern index对应一种SSB pattern，通过第一指示信息中携带的pattern index可以确定一种SSB pattern，进而获得该SSB pattern中每个SSB的时域位置。
进一步地，所述第一装置周期性地发送所述第一指示信息，所述第一指示信息中所携带的指示字段可以是ssb-PeriodicityServingCell。其中，在各个周期发送的第一指示信息所指示的pattern index可以相同，也可以不相同。
另一种指示方式是，利用SCS指示。由于在5G NR系统协议已经规定了SSB在时域上的位置，并且还规定了不同子载波间隔(SCS)可以支持的最大SSB个数，如图3示出的不同SCS对应的SSB图案。所以当所述第一指示信息中包括第一SCS时，根据该第一SCS以及第一SCS与SSB pattern之间的对应关系确定第一SSB的时域位置。例如，第一指示信息中指示的第一SCS等于30kHz，根据图3所示的对应关系，在30kHz时对应case B还是case C两种SSB的pattern，此时还需要进一步指示是case B还是case C，一般地在30kHz时设置方案C是主用的图案，则所述第一指示信息中还包括case C的指示信息。 所述第二装置在接收到第一装置发送的第一指示信息后，根据第一指示信息中携带的第一SCS等于30kHz和case C可以唯一地确定SSB的时域位置。
可选的，对于上述两种指示方式，在具体实现时，第一装置可利用5G NR已有的SIB字段来指示SSB所在的时域位置，如SSB-PositionsInBurst字段,该字段用于指示在包括SSB的半帧中用来传输SSB的时域位置。
另外，第一装置还发送在某个周期内未用于传输SSB资源的指示信息，进而第二装置在接收到该指示信息后，对于未被利用的SSB资源可用于传输其他资源，比如PDSCH资源等。进一步地，所述未用于传输SSB资源的位置指示信息可通过ssb-PositionsInBurst字段指示。
在利用第一指示信息来指示所述SSB的频域位置时，可以通过前述实施例一中的SSB频域起始位置、频域终止位置和频域宽度中的至少一种参数来指示，或者通过其他参数，例如参考位置和工作带宽下边界的偏移量，确定所述SSB的频域起始位置。具体地过程，可以参见实施例一中的描述，本实施例对此不再详细介绍。其中，在指示SSB的频域宽度时，可以设置该SSB的频域宽度为一固定值，比如20RB。
本实施例提供的方法，允许更精细的时频资源位置指示，即通过图案索引或SCS来指示具体地SSB的时域位置，从而使得各端装置可以在所述第一候选共享资源上除了该指示的SSB的资源之外的其他资源上进行共享，提高了资源的利用率。
需要说明的是，由于第一指示信息和第二指示信息是第一装置和第二装置交互的指示保留资源的信息，所以本实施例中对所述第一指示信息的配置和生成过程，同样适用于第二指示信息，所以第二装置生成和发送所述第二指示信息的过程与所述第一指示信息的过程相同，本实施例不再对该第二指示信息进行详细描述。
在本申请上述实施例一和实例二中，利用第一指示信息来指示第一装置保留的资源时，可以采用以下具体的实施方式：
一种可能的实施方式是，以位图方式指示。具体地，与前述实施例一中第三指示信息的“方式一”位图指示相似，将所述第一候选共享资源划分为多个时频块，每个时频块是由时域和频域围成的矩形面积。并且每个时频块的大小可以灵活配置。进一步地，通过定义二进制的字符串的比特值“1”和“0”来指示所述第一装置保留的资源，例如，定义比特值为“1”所对应的资源块为所述保留的资源，比特值为“0”所对应的资源块不是保留的资源。
另一种可能的实施方式是，通过时频图案清单(pattern list)方式来指示。其中所述时频pattern list由至少一个时频pattern ID组成，每个时频pattern ID可由一个二进制的字符串表示，并且对应一种资源。所述对应一种资源可以是SSB、PDCCH、PRACH等，具体是哪一个这里不做限制。例如pattern ID＝1对应SSB的时频块信息指示、pattern ID＝2对应Common PDCCH的时频块信息指示、pattern ID＝3对应PRACH的时频块信息指示等。如图16所示，时频pattern list中包括时频pattern 1至时频pattern m，其中，时频pattern 1可由二进制的n个二进制字符组成，每个二进制字符表示一个时频块，则从1至n的n个字符组成的字符串表示从时频块1至时频块n的总共n个时频资源。并且定义：字符比特值为“1”所对应的时频块是所述保留的资源，比特值为“0”所对应的时频块不是保留的资源。
举例说明，时频pattern ID＝1用于指示SSB资源时，例如通过二进制比特值表示时频块1至14为“00111100111100”时，表示在一个时间周期(比如14个OFDM符号)的时频块3～6和时频块9～12为用于传输SSB资源，其余的时频块1～2,7～8,13～14为不用于传输SSB的资源。其中，每个时频pattern ID所指示的资源类型和/或ID的取值范围均可以由协议规定，例如协议中规定ID的最大值是4或8。
本实施例中，通过位图或者时频pattern list的方式来指示保留的资源，从而达到更精细化的资源指示。

接收单元171，用于从所述第二装置接收第二指示信息，所述第二指示信息用于指示第二初始BWP的频域资源，所述第二初始BWP的频域资源为所述第二装置不与所述第一装置共享的资源，所述第二初始BWP的频域资源为所述第一候选共享资源的一部分。
