Description

频段状态指示方法和装置、频段状态确定方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及频段状态指示方法、频段状态确定方法、频段状态指示装置、频段状态确定装置和电子设备。
背景技术
随着通信技术的发展，授权频段已难以满足终端与基站的通信需要，例如在5G通信系统中，需要将基站与终端的通信拓展到了非授权频段。但是在使用非授权频段之前，需要先对见非授权频段进行检测，以确定非授权频段的状态，在非授权频段处于空闲的状态下，才能够占用非授权频段进行通信。
而在5G通信系统中，载波的带宽相对于4G通信系统中载波的带宽要大，为了提高检测的精度，可以将载波划分为多个子频段(也可以称作子带)，那么在非授权频段对应的载波包含多个子频段的情况下，对非授权频段进行检测，可以具体是对非授权频段中每个子频段进行检测。
在基站需要占用非授权频段的情况下，基站可以对非授权频段中每个子频段的状态进行检测，并基于每个子频段的状态生成检测结果，然后将检测结果发送至终端，从而终端不必对每个子频段进行检测，就可以根据接收到的检测结果确定每个子频段的状态。
基站在确定到空闲的子频段时，会立即占用空闲的子频段与终端进行通信，但是基站基于每个子频段的状态生成检测结果需要花费一段时间，所以不能在占用空闲的子频段时，立即将检测结果发送至终端，这就使得终端不能及时地确定每个子频段的状态。
发明内容
有鉴于此，本公开的实施例提出了频段状态指示方法、频段状态确定方法、频段状态指示装置、频段状态确定装置和电子设备，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种频段状态指示方法，适用于基站，所述方法包括：
检测非授权频段中n个子频段的状态，n≥1；
在所述n个子频段中存在空闲子频段的情况下，在占用所述空闲子频段的占用时长的起始位置，通过所述空闲子频段，向终端发送预设的n个状态指示信息，其中，所述n个状态指示信息用于指示所述n个子频段的状态。
根据本公开实施例的第二方面，提出一种频段状态确定方法，适用于终端，所述包括：
在非授权频段中空闲的子频段接收基站发送的预设的n个状态指示信息，n≥1；
根据所述n个状态指示信息，确定所述非授权频段中n个子频段的状态。
根据本公开实施例的第三方面，提出一种频段状态指示装置，适用于基站，所述装置包括：
状态监测模块，被配置为检测非授权频段中n个子频段的状态，n≥1；
信息发送模块，被配置为在所述n个子频段中存在空闲子频段的情况下，在占用所述空闲子频段的占用时长的起始位置，通过所述空闲子频段，向终端发送预设的n个状态指示信息，其中，所述n个状态指示信息用于指示所述n个子频段的状态。
根据本公开实施例的第四方面，提出一种频段状态确定装置，适用于终端，所述包括：
信息接收模块，被配置为在非授权频段中空闲的子频段接收基站发送的预设的n个状态指示信息，n≥1；
状态确定模块，被配置为根据所述n个状态指示信息，确定所述非授权频段中n个子频段的状态。
根据本公开实施例的第五方面，提出一种电子设备，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为实现上述任一实施例所述的频段状态指示方法。
根据本公开实施例的第六方面，提出一种电子设备，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为实现上述任一实施例所述的频段状态确定方法。
根据本公开的实施例，基站可以在占用时长的起始位置，通过该空闲子频段向终端发送预设的n个状态指示信息，以通过这n个状态指示信息向终端指示n个子频段的状态。
由于预设的n个状态指示信息是预先设定的，那么基站在占用空闲子频段之前已经存储了这n个状态指示信息，从而可以在占用空闲信道时，在占用时长的起始位置立即将n个状态指示信息发送给终端，使得终端可以及时接收到n个状态指示信息，以确定n个子频段的状态，进而可以根据确定的状态对相应的子频段及时采取适当的动作。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种频段状态指示方法的示意流程图。本实施例所示的方法可以适用于基站，所述基站可以与终端进行通信，例如可以基于4G协议与终端进行通信，也可以基于5G协议与终端进行通信。并且可以在授权频段(例如运营商网络对应的频段)与终端进行通信，也可以在非授权频段(例如Wi-Fi频段、蓝牙频段等)与终端进行通信。所述终端包括但不限于手机、平板电脑、可穿戴设备等电子设备。
如图1所示，所述频段状态指示方法可以包括以下步骤：
在步骤S1中，检测非授权频段中n个子频段的状态，n≥1；
在步骤S2中，在所述n个子频段中存在空闲子频段的情况下，在占用所述空闲子频段的占用时长的起始位置，通过所述空闲子频段，向终端发送预设的n个状态指示信息，其中，所述n个状态指示信息用于指示所述n个子频段的状态。
在一个实施例中，非授权频段可以包括n个子频段，例如图2所示，非授权频段可以包括4个子频段，子频段A、子频段B、子频段C和子频段D，每个子频段可以对应相等的带宽。
基站在需要占用非授权频段与终端进行通信时，可以对非授权频段中n个子频段进行检测，以确定n个子频段中每个子频段的状态，例如可以通过LBT(Listen Before Talk，先听后说)的方式对每个子频段进行检测，具体确定是否该子频段是否已被占用，在该子频段未被占用的情况下，可以确定该子频段空闲，在该子频段已被占用的情况下，可以确定该子频段非空闲。
在n个子频段中确定存在空闲子频段的情况下，可以占用该空闲子频段(例如存在多个子频段空闲，那么可以在其中选择一个子频段占用)，然后通过该空闲子频段与终端通信。
但是基站占用空闲子频段并非永久占用，而是需要确定一个占用时长，该占用时长可以称作信道占用时长(Channel Occupancy Time，简称COT)，基站在该占用时长内占用子频段。
根据本公开的实施例，基站可以在占用时长的起始位置，例如占用时长的一个时域单元(具体可以是符号、时隙等)，通过该空闲子频段向终端发送预设的n个状态指示信息，以通过这n个状态指示信息向终端指示n个子频段的状态。
由于预设的n个状态指示信息是预先设定的(例如可以根据前一次或前几次对n个子频段的检测结果设定)，那么基站在占用空闲子频段之前已经存储了这n个状态指示信息，从而可以在占用空闲信道时，在占用时长的起始位置立即将n个状态指示信息发送给终端，使得终端可以及时接收到n个状态指示信息，以确定n个子频段的状态，进而可以根据确定的状态对相应的子频段及时采取适当的动作。
图3是根据本公开的实施例示出的另一种频段状态指示方法的示意流程图。如图3所示，所述方法还包括：
在步骤S3中，根据所述n个子频段的状态更新所述n个状态指示信息；
在步骤S4中，在占用所述空闲子频段的占用时长的起始位置以外的其他位置， 将更新后的n个状态指示信息发送至所述终端。
在一个实施例中，由于预设的n个状态信息是预先设定的，所以与基站对于n个子频段的实际检测结果可能存在差异。基站在向终端发送预设的n个状态信息后，可以根据检测到的n个子频段的状态更新n个状态指示信息，以使更新后的n个状态指示信息能够准确地表示基站对于n个子频段的实际检测结果。
然后可以在占用所述空闲子频段的占用时长的起始位置以外的其他位置(其他位置也位于占用时长内，例如可以是起始位置之后的任一位置)，将更新后的n个状态指示信息发送至所述终端，从而使得终端可以根据更新后的n个状态指示信息准确地确定n个子频段的状态。
可选地，所述n个状态指示信息按照预设顺序排列，其中，所述预设顺序与所述n个子频段存在关联关系。
在一个实施例中，基站发送的n个状态指示信息可以按照预设顺序排列，而预设顺序则可以与n个频段存在关联关系，终端可以预先存储该关联关系，从而在接收到n个状态指示信息后，可以根据该关联关系，确定第i序位对应的第i个子频段，进而确定位于第i序位的第i个指示信息，用于指示的第i个子频段的状态，1≤i≤n。
例如以图2为例，子频段A、子频段B、子频段C、子频段D与预设顺序的对应关系为，子频段A对应第1序位，子频段B对应第2序位，子频段C对应第3序位，子频段D对应第4序位，而4个状态指示信息，状态指示信息a、状态指示信息b、状态指示信息c、状态指示信息d按照序位1、2、3、4排列。
那么可以确定状态指示信息a用于指示子频段A的状态，状态指示信息b用于指示子频段B的状态，状态指示信息c用于指示子频段C的状态，状态指示信息d用于指示子频段D的状态。
图4是根据本公开的实施例示出的又一种频段状态指示方法的示意流程图。如图4所示，所述向终端发送预设的n个状态指示信息包括：
在步骤S21中，向所述终端发送物理下行控制信道的信息，其中，在所述物理下行控制信道的信息中携带有所述n个状态指示信息。
在一个实施例中，基站可以在所述非授权频段向终端发送物理下行控制信道的信息，而所述n个状态指示信息则可以携带在物理下行控制信道的信息中。
可选地，所述n个子频段中第i子频段的状态包括以下之一：
为空闲、或为非空闲、或为可能空闲。
在一个实施例中，状态指示信息可以用于指示三种状态：空闲、非空闲和可能空闲，由于预设的n状态指示信息与基站对于n个子频段的实际检测结果可能存在差异，所以在通过状态指示信息指示子频段空闲和非空闲外，还可以指示子频段可能空闲。
需要说明的是，预设的n个状态信息可以根据前预设次数对n个子频段的检测结果来设定。
例如在预设次数为1的情况下，前一次对于第i个子频段的检测结果为第i个子频段空闲，那么预设的n个状态信息中对应第i个子频段的状态信息用于表征第i个子频段空闲；前一次对于第i个子频段的检测结果为第i个子频段非空闲，那么预设的n个状态信息中对应第i个子频段的状态信息用于表征第i个子频段非空闲；对于第i个子频段，过去没有对其进行检测，也即不存在前一次对i个子频段的检测结果，那么预设的n个状态信息中对应第i个子频段的状态可以表征第i个子频段可能空闲。
可选地，所述n个状态指示信息中的每个状态指示信息占用一个比特，或占用多个比特。
在一个实施例中，状态指示信息可以占用一个比特，也可以占用多个比特。
在状态指示信息占用多个比特的情况下，以占用两个比特为例，由于两个比特可以表示4种情况，因此针对每个子频段可以全面地表示上述空闲、非空闲和可能空闲3种状态。例如状态指示信息所表示的状态如表1所示：
状态指示信息 子频段的状态
00 空闲
01 非空闲
10 可能空闲
11 预留
表1
状态指示信息的值为00时，表示子频段空闲，状态指示信息的值为01时，表 示子频段非空闲，状态指示信息的值为10时，表示子频段可能空闲，状态指示信息的值为11为预留，暂不表示子频段的状态，以备后续使用时设置其表达的含义。
而在状态指示信息占用一个比特的情况下，由于一个比特只能表示2种情况，那么仅通过状态指示信息难以全面地表示上述空闲、非空闲和可能空闲3种状态，对于这种情况下，在后续实施例中进行说明。
可选地，所述n个状态指示信息中的每个状态指示信息占用一个比特，所述物理下行控制信道的信息中还携带有位置指示信息，其中，所述位置指示信息用于指示，所述物理下行控制信道的信息位于占用所述空闲子频段的占用时长的起始位置，或位于占用所述空闲子频段的占用时长的起始位置以外的其他位置。
在一个实施例中，在状态指示信息占用一个比特位的情况下，可以结合n个状态指示信息的位置对终端进行指示，使得同一个状态指示信息在所述n个状态指示信息在所述占用时长内位于不同位置时，表达不同的含义。
其中，可以预先设定位置与n个状态指示信息所指示的n个子频段的状态的关联关系，例如可以设定n个状态指示信息位于所述占用时长的起始位置时，状态指示信息中的1表示对应子频段可能空闲，0表示对应子频段非空闲；n个状态指示信息位于所述占用时长的起始位置以外的其他位置时，状态指示信息中的1表示对应子频段空闲，0表示对应子频段非空闲。
据此，可以结合n个状态指示信息在占用时长中所处的位置，通过一个比特的状态信息全面地表示空闲、非空闲和可能空闲3种状态。
相应地，终端在接收到n个状态指示信息后，可以确定n个状态指示信息在占用空闲子频段的占用时长中所处的位置，然后根据位置与n个状态指示信息所指示的n个子频段的状态的关联关系，查询所述位置对应的所述n个状态指示信息所指示的所述n个子频段的状态，从而根据查询到的n个状态指示信息，确定n个子频段的状态。
而为了使得终端能够确定n个状态指示信息在占用空闲子频段的占用时长中所处的位置，基站在发送的物理下行控制信道的信息中还可以携带有位置指示信息，通过位置指示信息指示所述物理下行控制信道的信息位于占用空闲子频段的占用时长的起始位置，还是位于占用空闲子频段的占用时长的起始位置以外的其他位置。
可选地，所述n个状态指示信息中的每个状态指示信息占用一个比特，所述物 理下行控制信道的信息的加扰信息用于指示，所述物理下行控制信道的信息位于占用所述空闲子频段的占用时长的起始位置，或位于占用所述空闲子频段的占用时长的起始位置以外的其他位置。
在一个实施例中，除了通过在物理下行控制信道的信息中额外设置位置指示信息，还可以通过物理下行控制信道的信息的加扰信息来指示所述物理下行控制信道的信息位于占用空闲子频段的占用时长的起始位置，还是位于占用空闲子频段的占用时长的起始位置以外的其他位置。
需要说明的是，位于占用时长的起始位置的物理下行控制信道的信息所携带的n个状态指示信息，可以是上述实施例中预设的n个状态指示信息。而位于占用时长的起始位置以外的其他位置(其他位置也位于占用时长内，例如可以是起始位置之后的任一位置)的物理下行控制信道的信息所携带的n个状态指示信息，则可以是上述实施例中更新后的n个状态指示信息。
其中，所述物理下行控制信道的信息可以通过无线网络临时标识(Radio Network Tempory Identity，简称RNTI)加扰，加扰信息可以是指无线网络临时标识本身，还可以是指用于对无线网络临时标识进行加扰的加扰信息。
可选地，所述物理下行控制信道为群组公共物理下行控制信道。
在一个实施例中，物理下行控制信道具体可以是群组公共物理下行控制信道(Group Common Physical Downlink Control Channel，简称GC-PDCCH)，通过群组公共物理下行控制信道，基站可以向属于特定群组的终端发送所述物理下行控制信道的信息。
可选地，所述n个子频段属于同一个载波，或其中至少一个子频段与其他子频段属于不同载波，或其中至少一个子频段对应预设载波的频段。
在一个实施例中，基站所检测的n个子频段，可以属于同一个载波，也可以属于不同载波，例如其中至少一个子频段与其他子频段属于不同载波，还可以有子频段对应预设载波的频段，也即子频段与预设载波的频段相同。而具体子频段属于上述哪种情况，可以根据实际需要设定。
图5是根据本公开的实施例示出的一种频段状态确定方法的示意流程图。本实施例所示的方法可以适用于终端，所述终端可以与基站(例如上述任一实施例所述的基站)进行通信，例如可以基于4G协议与基站进行通信，也可以基于5G协议与基站 进行通信。并且可以在授权频段(例如运营商网络对应的频段)与基站进行通信，也可以在非授权频段(例如Wi-Fi频段、蓝牙频段等)与基站进行通信。所述终端包括但不限于手机、平板电脑、可穿戴设备等电子设备。
如图5所示，所述频段状态确定方法可以包括以下步骤：
在步骤S1'中，在非授权频段中空闲的子频段接收基站发送的预设的n个状态指示信息，n≥1；
在步骤S2'中，根据所述n个状态指示信息，确定所述非授权频段中n个子频段的状态。
在一个实施例中，基站可以占用空闲的子频段来向终端发送预设的n个状态指示信息，由于预设的n个状态指示信息是预先设定的(例如可以根据前一次或前几次对n个子频段的检测结果设定)，那么基站在占用空闲子频段之前已经存储了这n个状态指示信息，从而可以在占用空闲信道时，在占用时长的起始位置立即将n个状态指示信息发送给终端，使得终端可以及时接收到n个状态指示信息，以确定n个子频段的状态，进而可以根据确定的状态对相应的子频段及时采取适当的动作。
图6是根据本公开的实施例示出的另一种频段状态确定方法的示意流程图。如图6所示，所述方法还包括：
在步骤S3'中，接收所述基站发送的根据所述n个子频段的状态更新后的n个状态指示信息；
在步骤S4'中，根据所述更新后的n个状态指示信息，确定所述n个子频段的状态。
在一个实施例中，由于预设的n个状态信息是预先设定的，所以与基站对于n个子频段的实际检测结果可能存在差异，基站在向终端发送预设的n个状态信息后，可以根据n个子频段的状态更新n个状态指示信息，以使更新后的n个状态指示信息能够准确地表示基站对于n个子频段的实际检测结果。然后在占用所述空闲子频段的占用时长的起始位置以外的其他位置(例如占用时长内起始位置之后的任一位置)，将更新后的n个状态指示信息发送至所述终端，终端则可以接收更新后的n个状态指示信息，从而根据更新后的n个状态指示信息准确地确定n个子频段的状态。
图7是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图7所示，所述n个状态指示信息按照预设顺序排列，所述根据所述n个状态指示信 息，确定所述n个子频段的状态包括：
在步骤S21'中，根据所述预设顺序与所述n个子频段的关联关系，确定所述n个状态指示信息中位于第i序位的第i个指示信息，用于指示所述第i序位在所述n个子频段中对应的第i个子频段的状态，1≤i≤n。
在一个实施例中，基站发送的n个状态指示信息可以按照预设顺序排列，而预设顺序则可以与n个频段存在关联关系，终端可以预先存储该关联关系，进而在接收到n个状态指示信息后，可以根据该关联关系，确定第i序位对应的第i个子频段，进而确定位于第i序位的第i个指示信息用于指示第i个子频段的状态，1≤i≤n。
例如以图2为例，子频段A、子频段B、子频段C、子频段D与预设顺序的对应关系为，子频段A对应第1序位，子频段B对应第2序位，子频段C对应第3序位，子频段D对应第4序位，而4个状态指示信息，状态指示信息a、状态指示信息b、状态指示信息c、状态指示信息d按照序位1、2、3、4排列。
那么可以确定状态指示信息a用于指示子频段A的状态，状态指示信息b用于指示子频段B的状态，状态指示信息c用于指示子频段C的状态，状态指示信息d用于指示子频段D的状态。
图8是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图8所示，所述在非授权频段中空闲的子频段接收基站发送的预设的n个状态指示信息包括：
在步骤S11'中，在所述非授权频段接收所述基站发送的物理下行控制信道的信息；
在步骤S12'中，在所述物理下行控制信道的信息中提取所述n个状态指示信息。
在一个实施例中，基站可以在所述非授权频段向终端发送物理下行控制信道的信息，而所述n个状态指示信息则可以携带在物理下行控制信道的信息中。终端可以接收基站发送的物理下行控制信道的信息，然后在所述物理下行控制信道的信息中提取所述n个状态指示信息。
可选地，所述n个子频段中第i子频段的状态包括以下之一：
空闲、或为非空闲、可能空闲。
在一个实施例中，状态指示信息可以用于指示三种状态：空闲、非空闲和可能 空闲，由于预设的n状态指示信息与基站对于n个子频段的实际检测结果可能存在差异，所以在通过状态指示信息指示子频段空闲和非空闲外，还可以指示子频段可能空闲。
例如预设的n个状态信息是根据前一次对n个子频段的检测结果设定，例如前一次对于第i个子频段的检测结果为第i个子频段空闲，那么预设的n个状态信息中对应第i个子频段的状态信息用于表征第i个子频段空闲；例如前一次对于第i个子频段的检测结果为第i个子频段非空闲，那么预设的n个状态信息中对应第i个子频段的状态信息用于表征第i个子频段非空闲；例如对于第i个子频段，过去没有对其进行检测，也即不存在前一次对i个子频段的检测结果，那么预设的n个状态信息中对应第i个子频段的状态可以表征第i个子频段可能空闲。
可选地，所述n个状态指示信息中的每个状态指示信息占用一个比特，或占用多个比特。
状态指示信息可以占用一个比特，也可以占用多个比特。
在状态指示信息占用多个比特的情况下，以占用两个比特为例，由于两个比特可以表示4种情况，因此针对每个子频段可以全面地表示上述空闲、非空闲和可能空闲3种状态。例如状态指示信息所表示的状态如表1所示，状态指示信息的值为00时，表示子频段空闲，状态指示信息的值为01时，表示子频段非空闲，状态指示信息的值为10时，表示子频段可能空闲，状态指示信息的值为11为预留，暂不表示子频段的状态，以备后续使用时设置其表达的含义。
而在状态指示信息占用一个比特的情况下，由于一个比特只能表示2种情况，那么仅通过状态指示信息难以全面地表示上述空闲、非空闲和可能空闲3种状态，对于这种情况下，在后续实施例中进行说明。
图9是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图9所示，所述n个状态指示信息中的每个状态指示信息占用一个比特，所述根据所述n个状态指示信息，确定所述非授权频段中n个子频段的状态包括：
在步骤S22'中，确定所述n个状态指示信息在占用所述空闲子频段的占用时长中所处的位置；
在步骤S23'中，根据所述位置与所述n个状态指示信息所指示的所述n个子频段的状态的关联关系，查询所述位置对应的所述n个状态指示信息所指示的所述n个 子频段的状态；
在步骤S24'中，根据查询到的所述n个状态指示信息，确定所述n个子频段的状态。
在一个实施例中，在一个实施例中，在状态指示信息占用一个比特位的情况下，可以结合n个状态指示信息的位置对终端进行指示，使得同一个状态指示信息在所述n个状态指示信息在所述占用时长内位于不同位置时，表达不同的含义。
其中，可以预先设定位置与n个状态指示信息所指示的n个子频段的状态的关联关系，例如位置与n个状态指示信息所指示的n个子频段的状态的关联关系如下：n个状态指示信息位于所述占用时长的起始位置时，状态指示信息中的1表示对应子频段可能空闲，0表示对应子频段非空闲；n个状态指示信息位于所述占用时长的起始位置以外的其他位置时，状态指示信息中的1表示对应子频段空闲，0表示对应子频段非空闲。
从而结合n个状态指示信息在占用时长中所处的位置，通过一个比特的状态信息全面地表示空闲、非空闲和可能空闲3种状态。
相应地，终端在接收到n个状态指示信息后，可以确定n个状态指示信息在占用空闲子频段的占用时长中所处的位置，然后根据位置与n个状态指示信息所指示的n个子频段的状态的关联关系，查询所述位置对应的所述n个状态指示信息所指示的所述n个子频段的状态，从而根据查询到的n个状态指示信息，确定n个子频段的状态。
例如终端确定n个状态指示信息在占用空闲子频段的占用时长中位于起始位置，根据位置与n个状态指示信息所指示的n个子频段的状态的关联关系，可以查询到n个状态指示信息中的1表示对应子频段可能空闲，0表示对应子频段非空闲，从而在第i个状态指示信息为1时，可以确定第i个子频段的状态为可能空闲，在第i个状态指示信息为0时，可以确定第i个子频段的状态为非空闲。
图10是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图10所示，所述确定所述n个状态指示信息在占用所述空闲子频段的占用时长中所处的位置包括：
在步骤S221'中，在所述物理下行控制信道的信息中提取位置指示信息；
在步骤S222'中，根据所述位置指示信息确定所述物理下行控制信道的信息位 于占用所述空闲子频段的占用时长的起始位置，或位于占用所述空闲子频段的占用时长的起始位置以外的其他位置。
在一个实施例中，为了使得终端能够确定n个状态指示信息在占用空闲子频段的占用时长中所处的位置，基站在发送的物理下行控制信道的信息中还可以携带有位置指示信息，终端根据位置指示信息可以确定所述物理下行控制信道的信息位于占用空闲子频段的占用时长的起始位置，还是位于占用空闲子频段的占用时长的起始位置以外的其他位置。
图11是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图11所示，所述确定所述n个状态指示信息在占用所述空闲子频段的占用时长中所处的位置包括：
在步骤S223'中，通过解扰信息对所述物理下行控制信道的信息进行解扰；
在步骤S224'中，根据所述解扰信息对应的加扰信息确定所述物理下行控制信道的信息位于占用所述空闲子频段的占用时长的起始位置，或位于占用所述空闲子频段的占用时长的起始位置以外的其他位置。
在一个实施例中，基站除了通过在物理下行控制信道的信息中额外设置位置指示信息，还可以通过物理下行控制信道的信息的加扰信息来指示终端物理下行控制信道的信息在所述占用时长内所处位置。
终端可以通过解扰信息对物理下行控制信道的信息进行解扰，然后根据解扰信息对应的加扰信息确定所述物理下行控制信道的信息位于占用空闲子频段的占用时长的起始位置，还是位于占用空闲子频段的占用时长的起始位置以外的其他位置。
终端除了按照上述图10和图11所示实施例的方式确定物理下行控制信道的信息在所述占用时长内所处的位置，还可以与基站预先约定，对于预设时间段内从基站接收到的所有物理下行控制信道的信息，都默认位于所述占用时长内的预设位置(例如起始位置)，从而对于从基站接收到的物理下行控制信道的信息，无需再进一步确定其在占用时长内的位置，而是可以默认其位于预设位置。
可选地，所述物理下行控制信道为群组公共物理下行控制信道。
在一个实施例中，物理下行控制信道具体可以是群组公共物理下行控制信道，通过群组公共物理下行控制信道，基站可以向属于特定群组的终端发送所述物理下行控制信道的信息。
可选地，所述n个子频段属于同一个载波，或其中至少一个子频段与其他子频段属于不同载波，或其中至少一个子频段对应预设载波的频段。
在一个实施例中，基站所检测的n个子频段，可以属于同一个载波，也可以属于不同载波，例如其中至少一个子频段与其他子频段属于不同载波，还可以有子频段对应预设载波的频段，也即子频段与预设载波的频段相同。而具体子频段属于上述哪种情况，可以根据实际需要设定。
在一个实施例中，终端根据确定的状态对相应的子频段及时采取适当的动作，从接收信息角度而言，可以包括监听对应的子频段；从而发送信息角度而言，可以包括直接占用对应的子频段，以及通过预设检测方式以外的其他检测方式检测所述第i个子频段空闲的情况下，占用所述第i个子频段，以及通过预设检测方式检测所述第i个子频段空闲的情况下，占用所述第i个子频段。
图12是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图12所示，所述方法还包括：
在步骤S5'中，在确定所述n个子频段中第i个子频段为空闲的情况下，监听所述第i个子频段，和/或在预设时长内，在需要占用所述第i个子频段时，在不检测所述第i个子频段的状态的情况下，或通过预设检测方式以外的其他检测方式检测所述第i个子频段空闲的情况下，占用所述第i个子频段，其中，所述预设检测方式相对所述其他检测方式检测的时长较长，且检测的结果较为准确。
在一个实施例中，终端在确定第i子频段空闲的情况下，可以继续监听第i子频段。并且还可以在预设时长内，在需要占用所述第i个子频段时，在不检测所述第i个子频段的状态的情况下，直接占用第i个子频段，以与基站通信；或者在预设时长内，在需要占用所述第i个子频段时，在通过预设检测方式以外的其他检测方式检测所述第i个子频段空闲的情况下，占用所述第i个子频段，以与基站通信。
其中，监听第i子频段包括但不限于接收控制信息，接收下行数据；终端占用第i个子频段与基站通信，包括但不限于向基站发送上行数据。
预设检测方式相对所述其他检测方式检测的时长较长，且检测的结果较为准确，例如预设检测方式可以是cat4检测方式，其他检测方式可以是cat2检测方式。
在本实施例中，终端在确定第i子频段空闲的情况下，可以保持对第i子频段的监听，以便及时接收到基站发送的控制信息、数据。
而且在确定第i子频段空闲的情况下，较大概率不会存在其他设备占用第i子频段，那么在需要占用第i子频段与基站进行通信的情况下，可以直接占用第i子频段，或者采用相对不严格的其他检测方式检测第i个子频段空闲时占用第i子频段，由于其他检测方式检测的时长相对较短，因此直接占用第i子频段，或者采用其他检测方式检测第i个子频段，耗时相对较短，有利于终端快速地完成向基站发送数据。
图13是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图13所示，所述方法还包括：
在步骤S6'中，在确定所述n个子频段中第i个子频段为可能空闲的情况下，监听所述第i个子频段，和/或在需要占用所述第i个子频段时，在检测所述第i个子频段空闲的情况下，占用所述第i个子频段。
在一个实施例中，终端在确定第i子频段可能空闲的情况下，可以继续监听第i子频段。并且在需要占用所述第i个子频段时，在检测(例如通过预设检测方式检测)所述第i个子频段空闲的情况下，占用所述第i个子频段，以与基站通信。
其中，监听第i子频段包括但不限于接收控制信息，接收下行数据；终端占用第i个子频段与基站通信，包括但不限于向基站发送上行数据。预设检测方式可以是检测的时长较长，且检测的结果较为准确的检测方式，例如cat4检测方式。
在确定第i子频段可能空闲的情况下，较大概率会存在其他设备占用第i子频段，那么在需要占用第i子频段与基站进行通信的情况下，可以采用相对严格的预设检测方式检测第i个子频段空闲时占用第i子频段，由于预设检测方式检测的结果较为准确，因此采用预设检测方式检测第i个子频段，可以确保终端能够在第i子频段未被占用的情况下占用第i子频段完成向基站发送数据。
在本实施例中，终端在确定第i子频段可能空闲的情况下，可以保持对第i子频段的监听，以便及时接收到基站发送的控制信息、数据。而且在需要占用第i子频段与基站进行通信的情况下，可以在检测第i个子频段空闲时占用第i子频段，以保证在准确地确定第i子频段空闲时才占用第i子频段。
图14是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图14所示，所述方法还包括：
在步骤S7'中，在确定所述n个子频段中第i个子频段为非空闲的情况下，停止监听所述第i个子频段，和/或在需要占用所述第i个子频段时，在检测所述第i个 子频段空闲的情况下，占用所述第i个子频段。
在一个实施例中，终端在确定第i子频段非空闲的情况下，可以停止监听第i子频段。并且在需要占用所述第i个子频段时，在检测(例如通过预设检测方式检测)所述第i个子频段空闲的情况下，占用所述第i个子频段，以与基站通信。其中，监听第i子频段包括但不限于接收控制信息，接收下行数据。
据此，可以避免终端对第i子频段进行不必要的监听，以便节省终端的电量，并且可以保证在准确地确定第i子频段空闲时才占用第i子频段。
图15是根据本公开的实施例示出的又一种频段状态确定方法的示意流程图。如图15所示，所述方法还包括：
在步骤S8'中，在确定所述n个子频段中第i个子频段为空闲或可能空闲的情况下，监听所述第i个子频段，和/或在需要占用所述第i个子频段时，在检测所述第i个子频段空闲的情况下，占用所述第i个子频段。
在一个实施例中，终端对于子频段为空闲和子频段为可能空闲的情况下，可以如图12和图13所示实施例，分别采取不同的动作。
也可以针对这两种情况采取相同的动作，例如在确定所述n个子频段中第i个子频段为空闲或可能空闲的情况下，可以继续监听所述第i个子频段，而在需要占用所述第i个子频段时，可以在检测所述第i个子频段空闲的情况下，占用所述第i个子频段。以便及时接收到基站发送的控制信息、数据，并且保证在准确地确定第i子频段空闲时才占用第i子频段。并且由于终端针对两种情况采取相同的动作，可以降低终端执行动作的复杂度。
可选地，所述在检测所述第i个子频段空闲的情况下，占用所述第i个子频段包括：
在通过预设检测方式检测所述第i个子频段空闲的情况下，占用所述第i个子频段，其中，所述预设检测方式相对所述预设检测方式以外的所述其他检测方式检测的时长较长，且检测的结果较为准确。
上述任一实施例所述的在检测所述第i个子频段空闲的情况下，占用所述第i个子频段，都可以是通过预设检测方式检测，其中，预设检测方式可以是检测子频段是否空闲的较为严格的检测方式，例如cat4检测方式，而通过较为严格的检测方式进行检测，检测结果将对准确，有利于保证在准确地确定第i子频段空闲时才占用第i 子频段。
