本申请涉及通信技术领域，尤其涉及一种共享信道的接入方法和接入设备。
背景技术
移动通信系统已经经历了第一代通信系统、第二代通信系统、第三代通信系统和正在经历的第四代通信系统。对于第四代通信系统，其采用的标准在国际上相对统一，为国际标准化组织3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)制定的长期演进(Long Term Evolution/Long Term Evolution-Advanced，LTE/LTE-A)，其下行基于正交频分多直接入(Orthogonal Frequency Division Multiple Access，OFDMA)，上行基于单载波频分多直接入(Single Carrier–Frequency Division Multiple Access，SC-FDMA)的接入方式，依据灵活的带宽和自适应的调制编码方式，达到下行峰值速率1Gbps，上行峰值速率500Mbps的高速传输。
MF(MulteFire)为在LTE R13 LAA(Licensed-Assisted Access，授权辅助接入)下行传输方法的基础上，新定义上行传输方法，该方法为可以独立工作于非授权频段的LTE技术,即stand-alone LTE-U。在非授权频段的传输,需要遵守该频段的信道接入规范，例如对于美国的3.5GHz非授权频段，CBRS(Citizens Broadband Radio Service，市民宽带无线电服务)，既要支持不同优先级用户间的信道共享，又要支持相同优先级的用户间的信道共享，同时既包括相同系统间的信道共享，也包括异系统间的信道共享。通常的共享信道方式，包括载波监听，其中载波监听需要发送端在前导报文Preamble 中指示占用情况。基于传统前导报文Preamble的载波监听方式，需要在现有MF传输前添加前导报文Preamble。
在实现本申请过程中，发明人发现现有技术中至少存在如下问题：
由于基于现有前导报文Preamble的载波监听方式，需要在现有MF传输前添加前导报文Preamble，因此信令开销较大。

实施例一
本申请实施例提供了一种共享信道的接入方法，如图1所示，该方法可以应用于基站或者用户设备中，该方法包括：
101、获取周边小区的系统消息。
具体的，系统消息是以信息广播形式向目标设备(基站和/或用户设备)发布的公开的消息、公告、通知、提示等，具有群发性，高可达性等消息特性。系统消息包含了空中接口上主要的无线网络参数，具体包括网络识别参数、小区的配置参数、系统控制参数和网络功能参数等，通过接收系统消息，目标设备能够准确的接入和进行网络选择，充分利用网络提供的各种服务，与网络达到良好的配合。
在一个可行的实施方案中，可以通过空口检测，获取所述系统消息。
具体的，进行空口检测时，基站或用户设备需要执行初始小区搜索过程，通过检测发现信号或同步信号与目标小区同步，在与目标小区同步后，可以获取到目标小区的系统消息，进而可以获取周边小区的系统消息。其中，周边小区是指能够和该基站或该用户设备进行通信的小区，周边小区包括具有相同网络类型的小区和不同网络类型的小区，具有相同网络类型的小区为邻小区。
102、根据所述系统消息，获取所述周边小区的配置参数。
具体的，配置参数中包含该小区的小区号、小区名称、载频配置、系统类型等信息，该小区可以根据对应的配置参数进行通信。
在一个可行的实施方案中，还可以向SAS(Spectrum Access  System，频谱接入控制系统)服务器或SON(Self-Organizing Networks，自组织网络)服务器或OAM(operations,administration and maintenance，操作、管理、维护)服务器发送携带有周边小区标识的请求消息，SAS服务器或SON服务器或OAM服务器在接收到该请求消息后，根据周边小区标识，将对应小区的配置参数发送给该基站或用户设备，如果是用户设备获取到该配置参数，该用户设备还可以将该配置参数上报给对应的基站。其中，SAS服务器或SON服务器或OAM服务器可以对小区的配置参数周期性进行更新。
103、根据所述配置参数，对所述周边小区进行监听，以进行共享信道接入。
在一个可行的实施方案中，可以根据所述配置参数，确定所述周边小区的系统种类，然后根据所述系统类型和所述配置参数，对所述周边小区进行监听。
在一个可行的实施方案中，当所述系统类型为LTE TDD时，可以根据所述配置参数，获取所述周边小区的上下行配置参数，然后根据所述上下行配置参数，对所述周边小区进行监听。
在一个可行的实施方案中，可以根据所述配置参数，确定所述周边小区的系统种类；当所述系统类型为LTE TDD时，获取所述周边小区的elMTA-RNTI(Enhanced Interference Management and Traffic Adaptation-Radio Network Temporary Identifier，增强的干扰管理和业务量自适应-无线网络临时标识)加扰的PDCCH(Physical Downlink Control Channel，物理下行控制信道)；根据所述PDCCH，获取所述周边小区的上下行配置参数；根据所述上下行配置参数，对所述周边小区进行监听。
具体的，针对支持增强的干扰管理和业务量自适应eIMTA的小区，在搜索PDCCH时，通过eIMTA-RNTI去解扰DCI format1C(Downlink Control Information format1C，下行控制信息格式1C)，当成功检测到eIMTA-RNTI加扰的DCI format 1C时，根据其指示来判断当前帧(子帧0被检测到时)或者下一帧(非子帧0被检测到 时)的PDCCH，然后在根据PDCCH获取周边小区的上下行配置信息。
在一个可行的实施方案中，根据所述配置参数，确定所述周边小区的系统种类；当所述系统种类为LAA或MF时，对所述周边小区的系统进行突发Burst检测，判断所述周边小区的下行结束位置和上行起止位置，以根据所述下行结束位置和所述上行起止位置对所述周边小区进行监听。
具体的，在进行Burst检测时，在基于能量检测的基础上可以通过CRS(Common Reference Signal，公共参考信号)序列的检测判断当前发送的小区，并可以进一步通过C-PDCCH(CC-RNTI(Common Control RNTI，公共控制无线网络临时标识)加扰的PDCCH)的检测判断下行结束以及上行的起止位置(ULduration(Up Link duration，上行持续时间))，其中，可以在与目标小区同步时获取目标小区标识PCI(Physical Cell Identity，物理小区标识)，然后根据PCI进行计算，获取CRS序列，并且可以建立CRS序列与、小区和配置参数的对应关系，在获取到CRS序列后，可以根据CRS序列和该对应关系，确定出对应的小区，即CRS序列可以作为小区索引的功能。
进一步的，通过上述提到的周边小区的上下行配置信息或周边小区的下行结束位置和上行起止位置获取到的信息与通过现有技术中前导报文Preamble获取到的信息相同，即周边小区的上下行配置信息或周边小区的下行结束位置和上行起止位置能够起到与现有技术中前导报文Preamble相同的作用，因此可以根据周边小区的上下行配置信息或周边小区的下行结束位置和上行起止位置进行载波监听。
在一个可行的实施方案中，在进行共享信道接入时，可以基于上述对周边小区的上行位置检测，当前小区的下行可以避免在目标小区的上行时间范围内发送，具体可以包括下行传输在目标小区的上行传输开始前结束和/或下行LBT(Listen Before Talk，先听后发) 在目标小区的上行时间范围内进行延迟，以及调度上行传输。基于上述信息，可以实现避免多个网络间的上下行干扰，协同发射时间等。
在一个可行的实施方案中，系统消息可以包括MIB(Master Information Block，主信息)、SIB1(System Information BlockType1，系统信息)、MIB-MF、SIB-MF1等信息，并可以根据MIB，SIB1，MIB-MF，SIB-MF1等信息，获取PLMN ID(Public Land Mobile Network IDentity，公共陆地移动网络身份标识号码)、ECGI(E-UTRAN Cell Global Identifier，演进型-通用移动通信系统陆地无线接入网小区全局标识符)、NHN ID(Neutral Host Network ID，中立主机网络标识)和PSP ID(Participating Service Provider ID，参与服务提供商标识)等小区的配置参数信息，例如，可以根据MIB或MIB-MF获取下行带宽和SFN(System Frame Number，系统帧号)等信息；可以根据SIB1获取PLMN-ID,ECGI等信息；可以根据SIB-MF1获取PLMN-ID,NHN-ID,PSP-ID，ECGI等信息，并且通过PLMN ID、ECGI、NHN ID和PSP ID等小区的配置参数信息可以区分本小区和当前检测到的目标小区的关系,例如如果是同一个PLNM所属的不同小区,那么可能会允许更高的干扰,但是不同PLMN所属的小区间,允许的互相干扰会较低,NHN和PSP的情况也类似。
在另一个可行的实施方案中，在上述方案的基础上，还可以通过下述方法进行共享信道接入：发送前导报文Preamble信号，且前导报文Preamble信号包含帧结构指示的时候，再根据前导报文Preamble中的指示协同的同时，继续监测C-PDCCH，当监测到的C-PDCCH指示与前导报文Preamble中的指示不同时，以C-PDCCH中的指示为准，因此可以支持DL的提前结束，上行的提前开始等来提高调度灵活性。例如，前导报文Preamble中指示的下行子帧个数为5个且上行子帧在第6个子帧开始，在第3个子帧上的C-PDCCH指示下一个子帧(即第四个子帧)结束以及上行子帧从第5个子帧 开始，则根据C-PDCCH中指示的帧结构为基础进行共享信道接入及协调。
在另一个可行的实施方案中，在上述方案的基础上，还可以基于前导报文Preamble和/或下行广播信号的占用检测的基础上，进一步结合能量检测门限进行判断是否传输以及何时传输上下行。例如，当检测到C-PDCCH当前为下行传输，且检测能量大于第一门限且小于第二门限(第一门限小于第二门限)时，则发起下行传输直至上行传输开始。又例如，针对具有相同PLMN ID或NHN ID的小区，其允许的能量检测门限为-60dBm；针对不同PLMN ID或NHN ID的小区，其允许的能量检测门限为-70dBm，当检测到的C-PDCCH所对应的目标小区与本小区的PLMN ID或NHN-ID相同且其检测大的能量为-65dBm时，允许本小区的下行发送，并发送到目标小区的上行开始之前。其中，下行广播信号可以包括C-PDCCH，发现信号Discovery Signal，SIB-MF1，SS(synchronization signal，同步信号)，PBCH(physical broadcast channel，物理广播信道)，CRS序列等。
其中，基于能量检测，可以通过与CRS序列相关获得，不同CRS序列可以获得不同小区的能量值，分别进行门限比较。当同时检测到多个小区的信号时，可以根据多个小区的上下行传输情况进行协调，例如避免本小区的下行信号干扰任意一个小区的上行信号。
在本申请实施例中，由于在获取周边小区的系统消息后，可以根据该系统消息，获取到周边小区的配置参数，在获取到所述配置参数后就完成了对周边小区的载波监听，然后再根据配置参数对周边小区进行监听，以进行共享信道的接入，在本申请实施例中，由于无需增加额外的信令，就可以实现对周边小区的载波监听，因此降低了信令的开销，以及由于在不获取前导报文Preamble或者不发送前导报文Preamble的情况下，仍然可以实现对周边小区的载波监听，并进行共享信道的接入，因此通过本申请实施例避免了在没有接收到前导报文Preamble或没有发送前导报文Preamble时，无法进行载波监听和进行信道共享的情况，同时，由于无需对当前的信令 进行修改，因此，本申请实施例不会对当前通信标准进行修改。

本实施例还提供一种非暂态计算机可读存储介质，所述非暂态计算机可读存储介质存储有计算机指令，所述计算机指令使所述计算机执行上述任一方法实施例所提供的方法。
实施例五
本实施例还提供一种计算机程序产品，所述计算机程序产品包括存储在非暂态计算机可读存储介质上的计算机程序，所述计算机程序包括程序指令，当所述程序指令被计算机执行时，计算机能够执行上述任一方法实施例所提供的方法。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统，装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统，装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如，多个单元或 组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用硬件加软件功能单元的形式实现。
上述以软件功能单元的形式实现的集成的单元，可以存储在一个计算机可读取存储介质中。上述软件功能单元存储在一个存储介质中，包括若干指令用以使得一台计算机装置(可以是个人计算机，服务器，或者网络装置等)或处理器(Processor)执行本申请各个实施例所述方法的部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
