非授权频段下的信息传输方法、网络设备及终端
相关申请的交叉引用
本申请主张在2017年10月20日在中国提交的中国专利申请号No.201710997028.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种非授权频段下的信息传输方法、网络设备及终端。
背景技术
在未来第五代(5th Generation，5G)通信系统中，或称为新空口(New Radio，NR)系统中，非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充，以帮助运营商对服务进行扩容。为了与NR部署保持一致，并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz、37GHz和60GHz频段。非授权频段的大带宽(80MHz或者100MHz)能够减小网络设备和终端的实施复杂度。由于非授权频段由多种无线接入技术(Radio Access Technology，RATs)共用，例如无线保真(Wireless Fidelity，WiFi)、雷达、长期演进授权频谱辅助接入(Long Term Evolution License Assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合某些规定(regulation)以保证所有设备可以公平的使用该资源，例如先听后说(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
在NR系统中，每个载波最大的信道带宽(Channel Bandwidth)可达到400MHz。但是考虑到终端能力，终端支持的最大带宽可以小于400MHz，且终端可以工作在多个小的带宽部分(Bandwidth Part，BWP)上。每个带宽部分对应于一个数值配置(Numerology)、带宽(Bandwidth)、频域位置(Frequency Location)。网络设备可以为终端配置多于一个BWP，这时网络设备需要告诉终端在哪一个BWP上工作，即激活(activate)哪一个BWP。BWP的激活或 去激活可以通过下行控制信息(Downlink Control Information，DCI)信令指示，终端在收到激活或去激活指令后，在相应的激活BWP(active BWP)上进行传输。其中，在非授权频段上，网络设备或者终端在激活BWP上传输前也需要进行信道侦听，当信道为空时，才可传输信息。当只针对激活的BWP进行信道侦听时，若侦听到信道为忙，则网络设备或者终端不能进行传输，但网络设备为终端配置其他未激活的BWP可能会空闲，这部分资源将会被浪费。

进一步地，步骤11具体为：分别对非授权频段中辅小区(Secondary cell，Scell)的第一BWP的传输信道进行侦听，得到信道侦听结果。其中，第一BWP为网络设备为终端的辅小区配置的至少一个BWP。
步骤12：若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则在传输信道空闲的BWP中选取至少一个BWP确定为第一激活BWP。
若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则可在这些传输信道空闲的BWP中选取至少一个BWP确定为第一激活BWP，其中，选取数目可根据终端上报的终端能力确定，如终端同时最多支持的激活BWP的数目等。其中，值得指出的是，网络设备确定第一激活BWP后会告知终端哪些BWP为第一激活BWP，以使终端对相应BWP进行激活。
步骤13：在第一激活BWP上，向终端发送信息。
网络设备在确定第一激活BWP后，在这些BWP上向终端发送下行信息。
其中，值得指出的是，终端可同时支持一个激活BWP，或至少两个激活BWP进行数据传输，下面本实施例将结合不同的终端能力对非授权频段下的信息传输方法做详细说明。
场景一、终端同时仅支持一个激活BWP。
虽然终端同时仅支持一个激活BWP，但网络设备仍可为终端配置至少两个BWP作为候选传输资源。
具体地，步骤11包括：分别对非授权频段中的第一BWP中的全部BWP进行侦听，得到信道侦听结果。即网络设备对终端所有的配置的BWP(configured BWP)进行侦听。
步骤12具体包括：当传输信道空闲的BWP中存在上一次传输所使用的激活BWP时，则所述激活BWP为第一激活BWP；或者，当传输信道空闲的BWP中不存在上一次传输所使用的激活BWP时，在传输信道空闲的BWP中选取一个BWP确定为第一激活BWP。
具体地，假设当终端同一时刻只能在一个active BWP上传输，终端在主 小区/主辅小区(Primary cell，Pcell/Primary Secondary cell，PScell)有一个active BWP(或称为BWPp)，在辅小区即非授权频段上有一个active BWP(或称为BWPs)。为了在非授权频段上进行下行传输，网络设备在终端所有的configured BWP上进行侦听。当侦听到传输信道空闲(idle)的BWP包括上一次使用的active BWPs时，则将该active BWPs确定为第一激活BWP，并在该active BWPs上进行下行信息的发送。当侦听到传输信道空闲的BWP不包括上一次使用的active BWP时，如图2中侦听到BWP1和BWP2空闲，BWP3为忙(busy)，传输信道空闲(idle)的BWP不包括上一次使用的active BWPs(如图2中BWP3)，网络设备可随机选取其中一个空闲的BWPs作为第一激活BWP(如图2中的BWP1)。
场景二、终端同时支持至少两个激活BWP。
具体地，步骤11包括：分别对非授权频段中的第一BWP中的全部BWP进行侦听，得到信道侦听结果。即网络设备对终端所有的配置的BWP(configured BWP)进行侦听。
若网络设备为终端配置的BWP数目等于终端最大支持的激活BWP时，步骤12包括：若信道侦听结果指示第一BWP中的全部BWP的传输信道空闲，则将第一BWP中的全部BWP确定为第一激活BWP；或者，若信道侦听结果指示第一BWP中的部分BWP的传输信道空闲，则将传输信道空闲的全部BWP确定为第一激活BWP，并继续对第一BWP中的其他BWP的传输信道进行侦听，若侦听到其他BWP的传输信道空闲，则将其他BWP补充至第一激活BWP中。其中，这里所说的其他BWP指的是第一BWP中暂时为忙的BWP。
具体地，假设终端同一时刻可以在多个active BWP上传输时，终端在Pcell/PScell有多个(如Np个)active BWP，在Scell即非授权频段上有Ns个active BWP。网络设备为终端配置Pcell/PScell上的BWP(configured BWP)的个数是Cp，在Scell上配置的BWP的个数是Cs，即第一BWP中BWP的个数为Cs。其中，Np≤Cp，Ns≤Cs。
其中，当Ns＝Cs时，若网络设备第一次侦听时则侦听到第一BWP中的所有BWP的传输信道均为空闲，那么确定第一BWP中的全部BWP为第一 激活BWP。如图3所示，若网络设备在首次侦听时，侦听到第一BWP中的部分BWP的传输信道空闲(如图3中BWP1和BWP2)，那么网络设备将传输信道空闲的所有BWP(如BWP1何BWP2)确定为第一激活BWP。进一步地，网络设备还可以继续对侦听到为忙的BWP(如图3中BWP3)进行侦听，在后续侦听到该BWP的传输信道空闲时，则将其确定为新的激活BWP并补充至第一激活BWP中。如图3所示，在起始时刻，网络设备对BWP1、BWP2和BWP3这三个BWP同时进行侦听，侦听结果显示BWP1和BWP2的传输信道空闲，BPW3的传输信道忙。这时网络设备将BWP1和BWP2确定为第一激活BWP，并继续对BWP3进行侦听。当侦听到BWP3的传输信道空闲时，将BWP3确定为新的激活BWP并补充至第一激活BWP。其中，值得指出的是，所有BWP之间是独立的，每个BWP的MCOT也是独立的。图3的示例中，BWP1和BWP2会先行结束MCOT，如果网络设备还有数据需要传输，则会继续针对BWP1和BWP2进行侦听。而BWP3的MCOT会在晚一些时候结束，视数据传输情况决定是否继续侦听。进一步地，若对BWP3进行侦听，侦听到BWP3为忙的时间较长，下行信息已经在BWP1和BWP2上完成传输，则放弃对BWP3的侦听。此外，还可预先设置每个BWP的最大侦听时间，若最大侦听时间内侦听到某个BWP的传输信道持续为忙，则放弃对该BWP的侦听。
若网络设备为终端配置的BWP数目小于终端最大支持的激活BWP时，步骤12还包括：若信道侦听结果指示第一BWP中的传输信道空闲的BWP数目大于或等于第一预设数目Ns，则在传输信道空闲的BWP中选取Ns个BWP确定为第一激活BWP；其中，Ns为正整数，且小于非授权频段中第一BWP的总数；或者，若信道侦听结果指示第一BWP中的传输信道空闲的BWP数目小于第一预设数目Ns，则将传输信道空闲的全部BWP确定为第一激活BWP，并继续对第一BWP中的其他BWP的传输信道进行侦听，若侦听到其他BWP的传输信道空闲，则将其他BWP补充至第一激活BWP中。
具体地，假设终端同一时刻可以在多个active BWP上传输时，终端在Pcell/PScell有多个(如Np个)active BWP，在Scell即非授权频段上有Ns个active BWP。网络设备为终端配置Pcell/PScell上的BWP(configured BWP) 的个数是Cp，在Scell上配置的BWP的个数是Cs，即第一BWP中BWP的个数为Cs。其中，Np≤Cp，Ns≤Cs。
其中，当Ns<Cs时，若网络设备第一次侦听时则侦听到第一BWP中的传输信道空闲的BWP的数目大于或等于Ns，那么在传输信道空闲的BWP中选取Ns个BWP确定为第一激活BWP。若网络设备侦听到第一BWP中传输信道空闲的BWP的数目小于Ns，那么网络设备将传输信道空闲的所有BWP确定为第一激活BWP。进一步地，网络设备还可以继续对侦听到为忙的BWP进行侦听，在后续侦听到该BWP的传输信道空闲时，则将其确定为新的激活BWP并补充至第一激活BWP中。
进一步地，若网络设备为终端配置的BWP数目小于终端最大支持的激活BWP时，步骤11还可通过以下方式实现：在非授权频段中选取第一BWP中第一预设数目Ns个BWP的传输信道进行侦听，得到信道侦听结果；其中，Ns为正整数，且小于非授权频段中第一BWP中BWP的总数。
步骤12包括：若信道侦听结果指示第一BWP中Ns个BWP的传输信道均空闲，则将Ns个BWP确定为第一激活BWP；或者，若信道侦听结果指示第一BWP的Ns个BWP中的部分BWP的传输信道空闲，则将传输信道空闲的全部BWP确定为第一激活BWP，并继续对第一BWP中的其他BWP或Ns个BWP中的其他BWP的传输信道进行侦听，若侦听到其他BWP的传输信道空闲，则将其他BWP补充至第一激活BWP中。
具体地，假设终端同一时刻可以在多个active BWP上传输时，终端在Pcell/PScell有多个(如Np个)active BWP，在Scell即非授权频段上有Ns个active BWP。网络设备为终端配置Pcell/PScell上的BWP(configured BWP)的个数是Cp，在Scell上配置的BWP的个数是Cs，即第一BWP中BWP的个数为Cs。其中，Np≤Cp，Ns≤Cs。当Ns<Cs时，网络设备在第一BWP中选出Ns个BWP进行侦听，若侦听到这Ns个BWP的传输信道均为空闲，则将Ns个BWP确定为第一激活BWP。若侦听到这Ns个BWP中仅有部分BWP(如Ns’个)的传输信道空闲，则将传输信道空闲的全部BWP确定为第一激活BWP，同时网络设备还继续在第一BWP中除Ns’个BWP之外的其他BWP上侦听，或者，在Ns个BWP中除Ns’个BWP之外的其 他BWP上侦听，从而另外选取Ns-Ns’个传输信道空闲的BWP补充至第一激活BWP中。
以上对终端仅支持一个BWP和至少两个BWP的场景中，网络设备如何侦听并确定第一激活BWP的方式进行了说明，另外，网络设备在确定第一激活BWP后还包括：在终端的主小区或主辅小区对应的至少一个BWP上，向终端发送用于指示第一激活BWP的下行控制信息DCI。即网络设备在确定第一激活BWP后，需要通过DCI将第一激活BWP的信息告知终端。也就是说，如图4所示，网络设备在确定第一激活BWP后，在该BWP上发送占用信号(reservation signal)占信道，同时在Pcell/PScell的下一个传输时间单元内(如slot)的DCI里面发送这些BWP的激活指令，其中，Pcell/PScell的DCI需要增加一个新的指示域(field)用来指示Scell的BWP激活/去激活。相应地，终端在收到Pcell/PScell上发送的指示BWP激活/去激活的DCI后，激活新的BWP。
进一步地，步骤13包括：在辅小区相对于DCI的发送时刻的下一个可用的传输时间单元内，在第一激活BWP上，向终端发送信息。其中，传输时间单元包括：时隙slot或微时隙mini-slot。网络设备在发送DCI后，在Scell的下一个可用的传输时间单元内，在第一激活BWP上向终端发送下行信息。其中，如果终端的重新调整(retuning)时间小于一个slot，网络设备还可以利用mini-slot，在发送DCI后的下一个mini-slot开始发送下行信息，即网络设备可根据终端能力在与DCI相同的slot内开始对终端进行mini-slot调度。
本公开实施例的非授权频段下的信息传输方法中，对于下行传输，网络设备在非授权频段上针对多个配置的BWP进行侦听，将传输信道空闲的BWP确定为第一激活BWP，并在第一激活BWP上向终端发送下行信息。这样通过对多个BWP进行侦听，在一个BWP忙时还可利用其它BWP进行传输，从而提高资源利用率。

以上实施例从网络设备侧介绍了不同场景下的非授权频段的信息传输方法，下面将结合附图对与其对应的终端侧非授权频段的信息传输方法及终端做进一步介绍。
如图7所示，本公开实施例还提供了一种非授权频段下的信息传输方法，应用于终端，包括：
步骤71：在终端的主小区或主辅小区对应的至少一个BWP上，接收网络设备发送的用于指示第一激活带宽部分BWP的下行控制信息DCI。
网络设备在确定第一激活BWP后，需要通过DCI将第一激活BWP的信息告知终端，以使终端知道激活或选择那些BWP。
步骤72：根据DCI激活第一激活BWP。
终端在获知第一激活BWP后，对这些BWP进行激活。
步骤73：在辅小区相对于DCI的发送时刻的下一个可用的传输时间单元内，在激活后的第一激活BWP上接收网络设备发送的信息。
其中，传输时间单元包括：时隙slot或微时隙mini-slot。网络设备在发送DCI后，在Scell的下一个可用的传输时间单元内，在第一激活BWP上向终端发送下行信息，相应地，终端在该传输时间单位内，可在第一激活BWP上接收到网络设备发送的信息。
以上实施例介绍了不同场景下的非授权频段的信息传输方法，下面将结合附图对与其对应的终端做进一步介绍。
如图8所示，本公开实施例的终端800，能实现上述实施例中在终端的主小区或主辅小区对应的至少一个BWP上，接收网络设备发送的用于指示第一激活带宽部分BWP的下行控制信息DCI；根据DCI激活第一激活BWP； 在辅小区相对于DCI的发送时刻的下一个可用的传输时间单元内，在激活后的第一激活BWP上接收网络设备发送的信息方法的细节，并达到相同的效果，该终端800具体包括以下功能模块：
第一接收模块810，用于在终端的主小区或主辅小区对应的至少一个BWP上，接收网络设备发送的用于指示第一激活带宽部分BWP的下行控制信息DCI；
第一激活模块820，用于根据DCI激活第一激活BWP；
第二接收模块830，用于在辅小区相对于DCI的发送时刻的下一个可用的传输时间单元内，在激活后的第一激活BWP上接收网络设备发送的信息；其中，传输时间单元包括：时隙slot或微时隙mini-slot。
本公开实施例的终端，根据网络设备发送的指示第一激活BWP的DCI对相应的BWP进行激活，并在激活后的BWP上接收网络设备发送的下行信息，由于第一激活BWP时网络设备在非授权频段上针对多个配置的BWP进行侦听确定的，可保证在一个BWP忙时还可利用其它BWP进行传输，从而提高资源利用率。
需要说明的是，应理解以上网络设备和终端的各个模块的划分仅仅是一种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些模块可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分模块通过处理元件调用软件的形式实现，部分模块通过硬件的形式实现。例如，第一接收模块可以为单独设立的处理元件，也可以集成在上述装置的某一个芯片中实现，此外，也可以以程序代码的形式存储于上述装置的存储器中，由上述装置的某一个处理元件调用并执行以上第一接收模块的功能。其它模块的实现与之类似。此外这些模块全部或部分可以集成在一起，也可以独立实现。这里所述的处理元件可以是一种集成电路，具有信号的处理能力。在实现过程中，上述方法的各步骤或以上各个模块可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指令完成。
例如，以上这些模块可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个特定集成电路(Application Specific Integrated Circuit， ASIC)，或，一个或多个信号处理器(digital signal processor，DSP)，或，一个或者多个现场可编程门阵列(Field Programmable Gate Array，FPGA)等。再如，当以上某个模块通过处理元件调度程序代码的形式实现时，该处理元件可以是通用处理器，例如中央处理器(Central Processing Unit，CPU)或其它可以调用程序代码的处理器。再如，这些模块可以集成在一起，以片上系统(system-on-a-chip，SOC)的形式实现。
进一步地，为了更好的实现上述目的，进一步地，图9为实现本公开各个实施例的一种终端的硬件结构示意图，该终端90包括但不限于：射频单元91、网络模块92、音频输出单元93、输入单元94、传感器95、显示单元96、用户输入单元97、接口单元98、存储器99、处理器910、以及电源911等部件。本领域技术人员可以理解，图9中示出的终端结构并不构成对终端的限定，终端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。在本公开实施例中，终端包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、以及计步器等。
其中，射频单元91，用于在处理器910的控制下进行信号的接收和发送；
处理器910，用于调用存储在存储器99上的计算机程序，以执行图8中所示的各个模块执行的方法。
本公开实施例的终端根据网络设备发送的指示第一激活BWP的DCI对相应的BWP进行激活，并在激活后的BWP上接收网络设备发送的下行信息，由于第一激活BWP时网络设备在非授权频段上针对多个配置的BWP进行侦听确定的，可保证在一个BWP忙时还可利用其它BWP进行传输，从而提高资源利用率。
应理解的是，本公开实施例中，射频单元91可用于收发信息或通话过程中信号的接收和发送，具体的，将来自基站的下行数据接收后，给处理器910处理；另外，将上行的数据发送给基站。通常，射频单元91包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器、双工器等。此外，射频单元91还可以通过无线通信系统与网络和其他设备通信。
