7、应用多(多业务被提及可以在其中运营，例如机器到机器(Machine to Machine，简称为M2M)、车辆到车辆(Vehicle to Vehicle，简称为V2V))。
在长期演进(Long-Term Evolution，简称为LTE)的演进过程中，LTE Rel-13版本于2014年9月份开始立项研究，其中一个重要内容就是LTE系统使用非授权载波工作。这项技术将使得LTE系统能够使用目前存在的非授权载波，大大提升LTE系统的潜在频谱资源，使得LTE系统能够获得更低的频谱成本。
但是，针对LTE系统和/或其他系统在非授权频谱上工作的情况，相关技术中LTE系统有一种利用用户设备(User Equipment，简称为UE)侧参与非授权载波资源竞争来提高获取资源概率的机制。基于此机制，当UE执行空闲信道评估(Clear Channel Assessment，简称为CCA)检测发现信道空闲时，会立刻向基站发送一个占用信号。此时会出现如下问题：如果UE1通过执行CCA，发现信道空闲，发送一个占用信号，而UE2在执行CCA时，发现信道被占用，而不进行占用信号的识别和测量，屏蔽到周围干扰，这样就会出现同小区或是同运营商下不同小区中多用户复用进行数据传输受到严重的干扰，影响系统的整体性能。并且，相关技术中的UE在检测非授权载波资源是否空闲时，是在整个非授权载波资源上进行检测，这样的话，整个非授权载波资源只能被同一个小区中的UE或同运营商下不同小区中的UE所使用，而能够使用的非授权载波资源也是有限的，由此可知，能够使用非授权载波资源的UE数量也是有 限制的，整个非授权载波资源的复用率相对较低。
针对相关技术中存在的资源复用率低的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种非授权载波的占用方法，图1是根据本发明实施例的第一种数据发送方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，第一组终端和/或第二组终端通过如下方式至少之一进行非授权载波带宽资源的空闲信道评估CCA和/或演进的空闲信道评估eCCA检测：第一组终端和/或第二组终端分别在预先配置给第一组终端和/或第二组终端的CCA和/或eCCA资源上进行CCA和/或eCCA检测；第一组终端和/或第二组终端分别在整个非授权载波带宽资源上进行CCA和/或eCCA检测，其中，第一组终端和第二组终端中均包括两个或两个以上的终端；
步骤S104，第一组终端和/或第二组终端根据检测结果确定后续数据发送。
通过上述步骤，在进行非授权载波带宽资源的CCA和/或eCCA检测时，是以一组终端来进行的，并且，在后续的数据发送时，也是一组终端在空闲的非授权载波上进行数据的发送，相对于相关技术中的单个终端执行CCA和/或eCCA检测，进行数据发送的方案而言，可以有效提高资源的复用率，可以同时实现多个终端发送数据，提高终端与其他节点的数据交换效率，从而解决相关技术中存在的资源复用率低的问题，达到了提高资源复用率的效果。
从上述步骤中可以看出，每组终端中是可以包括多个终端的，同组里边的终端之间是具备一定的特性的，在一个可选的实施例中，第一组终端中的终端具备如下特征至少之一：同一个小区中的终端；同一个运营商下不同小区中的终端；不同运营下不同小区中的UE；第二组终端中的终端具备如下特征至少之一：同一个小区中的终端；同一个运营商下不同小区中的终端；不同运营下不同小区中的UE。
预先配置的CCA和/或eCCA资源的配置方式可以有多种，在一个可选的实施例中，预先配置的第一组终端和/或第二组终端的CCA和/或eCCA资源均通过如下方式至少之一进行配置：由基站配置；由第一组终端和第二组终端之间协商配置。
其中，上述的第一组终端和/或第二组终端在预先配置的CCA资源和/或eCCA资源上进行CCA和/或eCCA检测之后，若发现信道空闲，还可以在发送用于占用空闲的信道的占用信号，包括：第一组终端和/或第二组终端确定信道空闲；第一组终端和/或第二组终端分别在各自执行CCA和/或eCCA检测的非授权载波带宽资源上发送占用信号；或者，第一组终端和/或第二组终端分别在整个非授权载波带宽资源上发送占用信号；第一组终端和/或第二组终端根据发送的占用信号确定后续数据发送。其中，当一组中的某个终端竞争到了预先配置的部分非授权载波资源或整个非授权载波资源后，该组中的其它终端都可以使用上述竞争到的预先配置的非授权载波资源或整个非授权载波资源进行数据的发送。也就是说，一组终端可以共同复用非授权载波资源。
在一个可选的实施例中，在第一组终端和/或第二组终端分别在整个非授权载波带宽资源上进行CCA和/或eCCA检测之后，还包括：第一组终端和/或第二组终端确定信道空闲；第一组终端和/或第二组终端检测到信道空闲之后，分别在整个非授权载波带宽资源上发送占用信号；或者，第一组终端检测到信道空闲后，在整个非授权载波带宽资源上发送占用信号，第二组终端检测到信道非空闲时，第二组终端接收并解析第一组终端发送的占用信号。
其中，上述的第一组终端和/或第二组终端发送的占用信号中均携带组标识、小区标识、运营商标识中的至少之一，且第一组终端和/或第二组终端发送的占用信号均包括以下形式至 少之一：信道探测参考信号SRS、前导码、主同步序列/辅同步序列PSS/SSS、预定标识。
在一个可选的实施例中，在第一组终端和/或第二组终端在整个非授权载波带宽资源上发送占用信号之前，还包括：第一组终端中的第一终端确定第一终端和预先占用整个非授权载波带宽资源的第二终端属于同一个小区或同一运营商不同小区中的终端；和/或，第二组终端中的第三终端确定第三终端和预先占用整个非授权载波带宽资源的第四终端属于同一个小区或同一运营商不同小区中的终端。其中，不同组中的终端也可以属于同一小区或同一运营商。
其中，当第一终端确定第一终端和第二终端属于同一个小区或同一运营商不同小区中的终端后，第一终端确定第一终端和第二终端之间的距离是否大于第一预定阈值和/或确定第一终端接收到的来自第二终端的信号强度是否小于第二预定阈值；如果判断结果为是，第一终端发送占用信号；否则，第一终端不发送占用信号；和/或，当第三终端确定第三终端和第四终端属于同一个小区或同一运营商不同小区中的终端后，第三终端确定第三终端和第四终端之间的距离是否大于第一预定阈值和/或确定第三终端接收到的来自第四终端的信号强度是否小于第二预定阈值；如果判断结果为是，第三终端发送占用信号；否则，第三终端不发送占用信号。
需要说明的是，上述的占用信号可以满足一定的规则，在一个可选的实施例中，上述占用信号占发送带宽的比例可以大于一个预定的比例，其中，可以通过如下方式至少之一使得占用信号占发送带宽的比例大于预定比例：重复占用信号；利用组标识、小区标识、运营商标识、其他预定标识中的至少之一加扰占用信号；修改频域上配置的子载波间隔的大小；在带宽频域资源的两端发送占用信号。该比例可以灵活设置，例如设置为80％。
在一个可选的实施例中，上述的CCA的图样、eCCA的图样、占用信号的图样以及数据发送图样中的至少之一均是可以由预调度信息指示的，即，预调度信息中可以携带有上述CCA的图样、eCCA的图样、占用信号的图样以及数据发送图样中的至少之一。
图2是根据本发明实施例的第一种占用信号的发送方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，第一组终端和/或第二组终端通过如下方式至少之一进行占用信号的发送：当第一组终端和/或第二组终端在各自执行的空闲信道评估CCA和/或演进的空闲信道评估eCCA资源上检测到信道空闲时，分别在各自执行CCA和/或eCCA的资源上发送占用信号；当第一组终端和/或第二组终端在各自执行的空闲信道评估CCA和/或演进的空闲信道评估eCCA资源上检测到信道空闲时，分别在整个非授权载波带宽上发送占用信号；当第一组终端和/或第二组终端分别在整个非授权载波带宽资源上执行空闲信道评估CCA和/或演进的空闲信道评估eCCA检测，检测到信道空闲时，第一组终端和/或第二组终端分别在整个非授权载波带宽资源上发送占用信号；当第一组终端和/或第二组终端分别在整个非授权载波带宽资源上执行空闲信道评估CCA和/或演进的空闲信道评估eCCA检测，检测到信道空闲时，第一组终端和/或第二组终端分别在各自执行CCA和/或eCCA的资源上发送占用信号；其中，第一组终端和第二组终端中均包括两个或两个以上的终端。
通过上述步骤，一组中的终端在检测信道是否空闲时，可以检测整个非授权载波资源是否空闲，也可以检测各自执行CCA和/或eCCA的资源是否空闲，并且，每种检验方式都可以对应两种占用信号的发送方式，一种是在整个非授权载波带宽上发送占用信号，一种是在各自执行CCA和/或eCCA的资源上发送占用信号。并且，从上述步骤中可以看出，无论是检测还是占用信号的发送都是由一组终端去执行的，可以有效提高资源的复用率，可以同时实现多个终端发送数据，提高终端与其他节点的数据交换效率，从而解决相关技术中存在的资源复用率低的问题，达到了提高资源复用率的效果。
在一个可选的实施例中，第一组终端和/或第二组终端发送的占用信号中均携带组标识、小区标识、运营商标识中的至少之一，且第一组终端和/或第二组终端发送的占用信号均包括以下形式至少之一：信道探测参考信号SRS、前导码、主同步序列/辅同步序列PSS/SSS、预定标识。
其中，在第一组终端和/或第二组终端在发送占用信号之前，还可以首先进行CCA和/或eCCA的检测，可以包括：第一组终端和/或第二组终端分别在预先配置给第一组终端和/或第二组终端的CCA和/或eCCA资源上进行CCA和/或eCCA检测；和/或，第一组终端和/或第二组终端分别在整个非授权载波带宽资源上进行CCA和/或eCCA检测。

预先配置的CCA和/或eCCA资源的配置方式可以有多种，在一个可选的实施例中，预先配置的第一组终端和/或第二组终端的CCA和/或eCCA资源均通过如下方式至少之一进行配置：由基站配置；由第一组终端和第二组终端之间协商配置。
在一个可选的实施例中，第一组终端和/或第二组终端在发送占用信号之后，还包括：根据配置的CCA和/或eCCA资源，进行数据发送；和/或，根据预调度信息，进行数据发送。

在一个可选的实施例中，第一组终端和/或第二组终端在整个非授权载波带宽资源上发送占用信号之前，还包括：第一组终端中的第一终端确定第一终端和预先占用整个非授权载波 带宽资源的第二终端属于同一个小区或同一运营商不同小区中的终端；和/或，第二组终端中的第三终端确定第三终端和预先占用整个非授权载波带宽资源的第四终端属于同一个小区或同一运营商不同小区中的终端。其中，不同组中的终端也可以属于同一小区或同一运营商。
其中，当第一终端确定第一终端和第二终端属于同一个小区或同一运营商不同小区中的终端后，第一终端确定第一终端和第二终端之间的距离是否大于第一预定阈值和/或确定第一终端接收到的来自第二终端的信号强度是否小于第二预定阈值；如果判断结果为是，第一终端发送占用信号；否则，第一终端不发送占用信号；和/或，当第三终端确定第三终端和第四终端属于同一个小区或同一运营商不同小区中的终端后，第三终端确定第三终端和第四终端之间的距离是否大于第一预定阈值和/或确定第三终端接收到的来自第四终端的信号强度是否小于第二预定阈值；如果判断结果为是，第三终端发送占用信号；否则，第三终端不发送占用信号。
需要说明的是，上述的占用信号可以满足一定的规则，在一个可选的实施例中，上述占用信号占发送带宽的比例可以大于一个预定的比例，其中，可以通过如下方式至少之一使得占用信号占发送带宽的比例大于预定比例：重复占用信号；利用组标识、小区标识、运营商标识、其他预定标识中的至少之一加扰占用信号；修改频域上配置的子载波间隔的大小；在带宽频域资源的两端发送占用信号。该比例可以灵活设置，例如设置为80％。

通过上述步骤，可知，每组终端在进行数据发送时，可以有两种发送方式，可以在与预先配置给该组终端的空闲信道评估CCA和/或演进的空闲信道评估eCCA资源相同的频域资源中发送数据，也可以在整个非授权载波带宽资源上，根据预调度信息，进行数据发送，从而增加了数据发送的灵活性，并且，从上述步骤中可以看出，在进行数据的发送时是由一组终端去执行的，可以有效提高资源的复用率，可以同时实现多个终端发送数据，提高终端与其他节点的数据交换效率，从而解决相关技术中存在的资源复用率低的问题，达到了提高资源复用率的效果。

步骤S502，第一组基站和/或第二组基站通过如下方式至少之一进行占用信号的发送：当第一组基站和/或第二组基站在各自执行的空闲信道评估CCA和/或演进的空闲信道评估eCCA的资源上检测到信道空闲时，分别在各自执行CCA和/或eCCA的资源上发送占用信号；当第一组基站和/或第二组基站在各自执行的空闲信道评估CCA和/或演进的空闲信道评估eCCA的资源上检测到信道空闲时，分别在整个非授权载波带宽上发送占用信号；当第一组基站和/或第二组基站分别在整个非授权载波带宽资源上执行空闲信道评估CCA和/或演进的空 闲信道评估eCCA检测，检测到信道空闲时，第一组基站和/或第二组基站分别在整个非授权载波带宽资源上发送占用信号；当第一组基站和/或第二组基站分别在整个非授权载波带宽资源上执行空闲信道评估CCA和/或演进的空闲信道评估eCCA检测，检测到信道空闲时，第一组基站和/或第二组基站在各自已协商好的资源中发送占用信号；其中，第一组基站和第二组基站中均包括两个或两个以上的基站。
通过上述步骤，一组中的基站在检测信道是否空闲时，可以检测整个非授权载波资源是否空闲，也可以检测各自执行CCA和/或eCCA的资源是否空闲，并且，每种检验方式都可以对应两种占用信号的发送方式，一种是在整个非授权载波带宽上发送占用信号，一种是在各自执行CCA和/或eCCA的资源上发送占用信号。并且，从上述步骤中可以看出，无论是检测还是占用信号的发送都是由一组基站去执行的，可以有效提高资源的复用率，可以同时实现多个基站发送数据，提高基站与其他节点的数据交换效率，从而解决相关技术中存在的资源复用率低的问题，达到了提高资源复用率的效果。
在一个可选的实施例中，第一组基站和/或第二组基站发送的占用信号中均携带组标识、小区标识、运营商标识中的至少之一，且第一组基站和/或第二组基站发送的占用信号均包括以下形式至少之一：前导码、主同步序列/辅同步序列PSS/SSS、预定标识。
其中，第一组基站和/或第二组基站在发送占用信号之前，还包括：第一组基站和/或第二组基站分别在各自已协商好的给第一组基站和/或第二组基站的CCA和/或eCCA资源上进行CCA和/或eCCA检测；和/或，第一组基站和/或第二组基站在整个非授权载波带宽资源上进行CCA和/或eCCA检测。
从上述步骤中可以看出，每组基站中是可以包括多个基站的，同组里边的基站之间是具备一定的特性的，在一个可选的实施例中，第一组基站中的基站具备如下特征至少之一：同一个运营商下的基站；不同运营下的基站；第二组基站中的基站具备如下特征至少之一：同一个运营商下的基站；不同运营下的基站。其中，当一组中的某个基站竞争到了预先配置的部分非授权载波资源或整个非授权载波资源后，该组中的其它基站都可以使用上述竞争到的预先配置的非授权载波资源或整个非授权载波资源进行数据的发送。也就是说，一组基站可以共同复用非授权载波资源。
在一个可选的实施例中，第一组基站和/或第二组基站在发送占用信号之后，还包括：根据配置的CCA和/或eCCA资源，进行数据发送。
在一个可选的实施例中，第一组基站和/或第二组基站在整个非授权载波带宽资源上发送占用信号包括：第一组基站和/或第二组基站在检测到信道空闲之后，第一组基站和/或第二组基站在整个非授权载波带宽资源上发送占用信号；或者，第一组基站检测到信道空闲后，在整个非授权载波带宽资源上发送占用信号，第二组基站检测到信道非空闲时，第二组基站接收并解析第一组基站发送的占用信号。
其中，第一组基站和/或第二组基站在整个非授权载波带宽资源上发送占用信号之前，还包括：第一组基站中的第一基站确定第一基站和预先占用整个非授权载波带宽资源的第二基 站属于同一运营商中的基站；和/或，第二组基站中的第三基站确定第三基站和预先占用整个非授权载波带宽资源的第四基站属于同一运营商中的基站。其中，不同组中的基站也可以属于同一运营商。
其中，当第一基站确定第一基站和第二基站属于同一运营商下的基站后，第一基站确定第一基站和第二基站之间的距离是否大于第一预定阈值和/或确定第一基站接收到的来自第二基站的信号强度是否小于第二预定阈值；如果判断结果为是，第一基站发送占用信号；否则，第一基站不发送占用信号；和/或，当第三基站确定第三基站和第四基站属于同一运营商下的基站后，第三基站确定第三基站和第四基站之间的距离是否大于第一预定阈值和/或确定第三基站接收到的来自第四基站的信号强度是否小于第二预定阈值；如果判断结果为是，第三基站发送占用信号；否则，第三基站不发送占用信号。
需要说明的是，上述的占用信号可以满足一定的规则，在一个可选的实施例中，上述占用信号占发送带宽的比例可以大于一个预定的比例，其中，可以通过如下方式至少之一使得占用信号占发送带宽的比例大于预定比例：重复占用信号；利用组标识、小区标识、运营商标识、其他预定标识中的至少之一加扰占用信号；修改频域上配置的子载波间隔的大小；在带宽频域资源的两端发送占用信号。该比例可以灵活设置，例如设置为80％。
在一个可选的实施例中，上述的CCA的图样、eCCA的图样、占用信号的图样以及数据发送图样中的至少之一均是可以由预调度信息指示的，即，预调度信息中可以携带有上述CCA的图样、eCCA的图样、占用信号的图样以及数据发送图样中的至少之一。

通过上述步骤，可知，每组基站在进行数据发送时，可以有两种发送方式，可以在与预先配置给该组基站的空闲信道评估CCA和/或演进的空闲信道评估eCCA资源相同的频域资源中发送数据，也可以在整个非授权载波带宽资源上，根据预调度信息，进行数据发送，从而增加了数据发送的灵活性，并且，从上述步骤中可以看出，在进行数据的发送时是由一组基站去执行的，可以有效提高资源的复用率，可以同时实现多个基站发送数据，提高基站与其他节点的数据交换效率，从而解决相关技术中存在的资源复用率低的问题，达到了提高资源复用率的效果。

下面，结合具体的实施例来说明组内的终端或基站如何识别在已竞争到的非授权载波资源上发送的占用信号，以及规避周围干扰，以便确定可以在竞争到的非授权载波资源复用的其他终端或基站：
下面以第一组终端和第二组终端为例，对本发明进行说明，当然，下述的实施例对于基站组同样适用。
在该实施例中，主要涉及如下方面：具有竞争能力的UE(同上述的第一组终端中的UE/或第二组终端中的UE)在特定的非授权载波上执行空闲信道评估(Clear Channel Assessment，简称为CCA)和/或eCCA并发送占用信号的操作，占用信号特有功能部分和占用信号满足发送信号占发送带宽80％以上管制要求的发送规则。
UE在特定的(该“特定的”可以是整个非授权载波资源，也可以是预先配置的部分非授权载波资源，其中，该配置方式也可以为多种，如频域上采用频分等)非授权载波资源上执行CCA和/或eCCA后的操作，可以包括如下步骤：
当UE在执行CCA和/或eCCA时检测到非授权载波空闲后，该UE发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是与该UE同组的其他UE，例如，可以是同小区或是同运营商不同小区的UE发送的，且 两个UE间距离很近时，则该UE可以不发送占用信号。可选的，该UE也可以发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是同组的UE发送的，且两个UE间距离很远时，则该UE为了屏蔽周围的隐藏节点而需要发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是不同组的UE发送的，则UE停止执行CCA和/或eCCA，不发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且不能检测出预先占用非授权载波的UE是否是同组中的UE时，则该UE继续执行CCA和/或eCCA。
UE发送的占用信号，必须具备的特征如下：
特征一：距离较远且执行CCA和/或eCCA检测到信道空闲的UE彼此间需独立发送占用信号。
特征二：同一组中执行CCA和/或eCCA检测到信道空闲的UE之间是相互不互斥的。
上述特征一主要是用于避免UE侧隐藏节点的问题，其是指竞争成功的UE彼此之间距离较远时必须发送占用信号，以消除隐藏节点对其造成干扰。
上述特征二是指同组中的UE可以通过某种方式识别出这个占用信号是自己组中UE发送的而忽略发送的占用信号，认为信道为空闲，发送自己的占用信号。
对于上述的让本组的其他UE识别竞争成功UE发送的占用信号的方法，可采用下述方法：
信号检测方法。即执行CCA和/或eCCA检测到信道空闲的UE，在发送的占用信号中携带组标识，例如：组标号、小区标识Cell ID或者运营商标识，可选的，还可以携带发送资源的位置信息。还在继续执行CCA和/或eCCA的UE在检测到该占用信号中携带与自己相同的组标识，则认为此非授权载波空闲，然后发送自己的占用信号。反之，认为信道忙，停止检测信道。
上述方法中通过检测来获知占用信号是否是本组中的UE所发送，其中，检测依据主要是通过检测发送占用信号中携带的组标识。这里，发送的占用信号可以是以下形式至少之一：SRS、Preamble、PSS/SSS、简单的标识。
其中，执行CCA和/或eCCA检测到信道空闲的UE，发送具有UE特有功能占用信号，UE发送的占用信号特有功能为占用信道的功能和用于测量的功能。
UE侧发送的占用信号主要用于占用信道，其主要是指执行CCA和/或eCCA检测到信道空闲的UE，在CCA和/或eCCA检测成功后立刻在非授权载波上发送一个占用信号，这个信号可以是无意义的信号、携带简单的占用标识的信号、携带Cell ID的信号、携带运营商标识的信号或是携带UE ID和Cell ID及这些信号的组合。在此功能下，发送的占用信号应该至少要能优先的占住信道，其次，可以在发送的信号中携带有利于继续执行CCA和/或eCCA的 UE识别出是否是本组中的UE发送的占用信号的标识，为多用户复用传输做准备。
其中，对于不同组中的UE，发送的占用信号至少要携带组标识或小区标识或运营商标识，继续执行CCA和/或eCCA的UE检测到占用信号是不同组的UE发送的，则立刻停止检测，认为信道已被占用。
UE侧发送的占用信号主要用于测量的功能。其主要是指具有竞争能力的UE在进行CCA和/或eCCA检测时，对周围接收到的信号强度进行一个测量判断。对于执行CCA和/或eCCA检测发送信道空闲的UE，在进行周围信号强度判断时，认为周围信号强度没有达到干扰门限预设值，从而认为该信道是一个近乎于干净的信道，所以发送了一个占用信号。而对于继续执行CCA和/或eCCA检测的其他UE，继续评估来自周围其他UE的信号强度大小以此判断信道是否空闲。如果已发占用信号UE对继续执行CCA和/或eCCA检测的UE的信号强度没有达到干扰门限预设值，则认为信道空闲，便会发送一个占用信号。进而根据接收到已发送占用信号的信号强度获知周围正在发送占用信号UE与继续测量周围干扰UE间的距离(可以根据公式PR＝PT/rn来计算距离)，这个距离信息可以用于后续其他用途。
上述发送的占用信号必须满足非授权载波上发送信号占发送带宽的80％(或其他的比例)的管制要求，基于此，可以采用以下规则至少之一满足管制要求：
规则一：占用信号在频域上简单的重复。
规则二：频域上从低到高的顺序依次发送预先指定的占用信号，在剩余频域资源上发送按照组标识、UE ID、小区ID、运营商标识进行加扰的占用信号序列。
规则三：修改频域上子载波间隔大小。如子载波间隔可以为1.25kHz、2.5kHz、3.75kHz、5kHz、7.5kHz、10kHz、15kHz、20kHz、30kHz、60kHz、120kHz等。
规则四：在带宽频域资源的两端发送占用信号，中间的频域资源上不发送指定序列或是空置出来用于发送数据等其他信息或是什么都不发。
通过上述实施例，可以有效解决LTE系统中UE在特定的非授权载波上执行CCA检测到信道空闲，发送占用信号，但本组其他UE只检测不做相应操作而导致其他系统中节点以为信道空闲进行传输造成严重干扰的问题，通过本专利提供的方法，可以很好的规避具有竞争能力的UE附近出现的隐藏节点问题和辅助进行节点周围干扰情况测量，这样做不仅可以确保特定的非授权载波资源被真正的占住，还可以获知节点周围干扰情况及节点间距离，进一步提高了非授权载波资源的利用率。此外，提供了多种满足发送信号占发送带宽80％以上的方法，并赋予新的意义。
下面结合具体实施例对本发明进行说明：
实施例一：
图13是根据本发明实施例一的异系统共存场景中解决隐藏节点示意图；
对于非授权载波上LTE系统和Wi-Fi系统共存场景，针对eNB覆盖范围下两个具有竞争能力的UE相距较远且彼此邻近都有Wi-Fi系统中的站点(Station，简称为STA)和接入点(Access Point，简称为AP)节点的情况，如图13所示。对于UE在特定的非授权载波资源上执行CCA和/或eCCA。
当UE在执行CCA和/或eCCA时检测到非授权载波空闲后，UE发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是同组的UE发送的，且两个UE间距离很远时，则UE为了屏蔽周围的隐藏节点而需要发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是不同组的UE发送的，则UE停止执行CCA和/或eCCA，不发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且不能检测出组标识时，UE继续执行CCA和/或eCCA。
具体到本实施例中，UE1、UE2和UE3都是具有竞争能力的UE，UE1和UE2是同组中的UE，UE3是与UE1、UE2不同组中的UE，它们在执行CCA和/或eCCA检测特定的非授权载波时，只有UE1执行CCA和/或eCCA成功，检测到信道空闲，则UE1立刻发送携带有组标识的占用信号。
当UE2在继续执行CCA和/或eCCA检测信道忙，且检测到占用信号是同组下的UE1发送的，同时UE1和UE2之间距离相对较远，UE2为了屏蔽到周围隐藏节点，例如，STA2，则发送一个占用信号。
当UE3在继续执行CCA和/或eCCA检测信道忙，且检测到占用信号中携带的组标识不是自己组的，则认为信号忙，从而停止检测，进一步也不会在特定的非授权载波上发送占用信号。
如果UE2和UE3在继续执行CCA和/或eCCA时检测信道忙，且不能检测出组标识，UE2和UE3继续执行CCA和/或eCCA。
通过上述实施例能够有效的规避成功执行CCA和/或eCCA竞争到特定非授权载波UE周围的隐藏节点问题。
实施例二：
图14是根据本发明实施例二的异系统共存场景中解决隐藏节点示意图；
本实施例给出的LTE和Wi-Fi共存的场景中，针对eNB1覆盖范围下两个具有竞争能力的UE相距较近，eNB2是与eNB1同一运营商，eNB2中有一个UE，但eNB3是与eNB1和eNB2 不同的运营商基站，且与eNB1覆盖重叠处有一个UE，同时这些UE附近都有Wi-Fi系统中的STA和AP节点的情况，如图14所示。
对于UE在特定的非授权载波资源上执行CCA和/或eCCA，当UE在执行CCA和/或eCCA时检测到非授权载波空闲后，UE发送占用信号。
当UE执行CCA和/或eCCA检测到非授权载波信道忙，且检测到非授权载波上的占用信号是同组的UE发送的，且两个UE间距离很近(即两个UE的覆盖范围几乎重叠)时，则UE可以不发送占用信号。
具体到本实施例中，UE1、UE2、UE3和UE4都是具有竞争能力的UE，UE1、UE2和UE3是同组下的UE，且UE1和UE2是紧挨的两个UE，UE4是另一组中的UE，UE1、UE2、UE3和UE4在执行CCA和/或eCCA检测特定的非授权载波时，只有UE1执行CCA和/或eCCA成功，检测到信道空闲，则UE1立刻发送携带有组标识的占用信号。
当UE2在继续执行CCA和/或eCCA检测信道忙，且检测到占用信号是同组下的UE1发送的同时UE1和UE2之间距离相对较近，由于与之邻近的UE1已经发送了占用信号屏蔽了周围隐藏节点，则UE2可以不再发送占用信号。
当UE3在继续执行CCA和/或eCCA检测信道忙，且检测到占用信号中携带的组标识与自己相同，则认为信道空闲，发送一个占用信号。
当UE4在继续执行CCA和/或eCCA检测信道忙，且检测到占用信号中携带的组标识与自己不同，则认为信道忙，从而停止检测，进一步也不会在特定的非授权载波上发送占用信号。
如果UE2、UE3和UE4在继续执行CCA和/或eCCA时检测信道忙，且不能检测出组标识，UE2、UE3和UE4继续执行CCA和/或eCCA。
实施例三：
图15为根据本发明实施例三的UE执行CCA和/或eCCA和识别占用信号的整体流程图；
对于UE侧，具有竞争非授权载波资格的UE如何在特定的非授权载波上执行CCA和/或eCCA并发送占用信号占用信道的整体流程如图15所示，包括如下步骤：
步骤S1502：具有竞争资格的所有UE在指定竞争的非授权载波上执行CCA和/或eCCA检测，其中，该指定的非授权载波可以是预定位置(例如，奇数位置，或偶数位置)上的非授权载波，也可以是整个非授权载波。
本步骤中，具有竞争资格的UE，包括：接收到UL grant的UE、有数据发送的UE、基站指定的分组中的UE等。这些具有竞争资格的UE在基站预先指定的非授权载波上进行CCA检测。
对于上述UE进行CCA和/或eCCA检测，这里可以假定每个UE执行CCA和/或eCCA的起始时刻是相同的或是不同的，以及计算来自周围干扰的方式不同。这里对于CCA和/或eCCA检测和识别信号，可以按照信号检测和干扰计算方法来实现。
步骤S1504，UE执行CCA和/或eCCA检测到信道空闲。
步骤S1506，上述UE在其非授权载波上立刻发送占用信号。
在上述步骤中，执行CCA和/或eCCA成功的UE立刻在竞争到的非授权载波上发送占用信号。这里的发送的占用信号中携带了组标识，例如，组标号、Cell ID、携带运营商标识。用于下一步中其他UE检测信道和进行信号解析。
步骤S1508，继续进行CCA和/或eCCA检测的其他UE检测和识别。
步骤S1510，根据检测和识别结果进行发送占用信号处理或进行放弃检测的处理。其中，对于UE侧，继续执行CCA和/或eCCA检测的UE，发现特定的非授权载波被占用，进一步检测信号中信息，如果检测到占用信号中携带的组标识和自身所在的组相同，则认为信道空闲。根据实施例一情况，正在检测的UE和已发送占用信号UE间的距离较远，则该UE发送占用信号，规避该UE周围的隐藏节点。根据实施例二中的情况，则该UE可以不发送占用信号，可以认为周围隐藏节点已被屏蔽。如果检测到占用信号中携带的组标识相同，则UE认为信道空闲，发送占用信号。如果检测到占用信号中携带的组标识不同，则该UE认为信道已被占用，从而停止继续执行CCA和/或eCCA检测。
实施例四：
图16为根据本发明实施例四的未竞争成功的UE处理过程示意图；
如图16(a)所示，具有竞争资格的UE有可能有一部分UE或是只有一个UE成功竞争到非授权载波，而其他竞争失败的UE可以按照如下方法来处理：
第一种：CCA和/或eCCA失败的UE，不再继续执行CCA和/或eCCA，认为信道已经被占，从而停止进行该信道的能量检测。
第二种：CCA和/或eCCA失败的UE，继续执行CCA和/或eCCA，检测信道是否空闲。这里继续检测信道空闲的意思是指检测和识别占用信号是否是同组下的UE发送的。检测到信道空闲的未竞争成功的UE，立刻发送占用信号。下面进一步详述CCA和/或eCCA失败的UE，继续执行CCA和/或eCCA的情况。
具体到本实施例中，如图16(b)所示。假定UE1、UE2和UE3是同一个组下的UE。如果在执行CCA和/或eCCA的过程中UE1成功竞争到非授权载波，则UE1立刻发送占用信号。UE2和UE3检测到信道上的占用信号，解析占用信号信息，如果UE1发送的占用信号中携带的组标识，例如组标识与其自身携带的相同，则UE2和UE3认为信道空闲，立刻发送占用信号，如果还有诸如UE4或是UE5执行CCA和/或eCCA，则采用上述同样的方法处理。
假定UE1、UE2和UE3是同一个组下的UE。如果UE1执行CCA和/或eCCA成功竞争到非授权载波，则UE1立刻发送占用信号。UE2和UE3在继续执行CCA和/或eCCA的过程中检测信道状况，如果检测到信道上已有占用信号，则解析占用信号中携带的组标识，例如组标号、小区标识Cell ID、运营商标识。如果UE2和UE3发现它们的组标识相同，则UE2和UE3认为信道空闲，可以立刻发送占用信号(当距离较近时，也可以不发送占用信号)。如果UE2和UE3发现它们的组标识不同，则UE2和UE3认为信道忙，从而停止检测该非授权载波。
未竞争成功的UE在继续执行CCA和/或eCCA的过程中，还可以进一步判断UE之间的相对距离是不是大于第一预定阈值，或者UE之间的信号能量是否小于第二预定阈值，其中，该信号能量可以是周围节点的信号能量，从而确定解析正确的UE是否需要发送占用信号。
实施例五：
图17是根据本发明实施例五的UE发送占用信号用于测量功能的示意图；
本实施例主要详述进行CCA和/或eCCA检测到信道空闲的UE，发送占用信号用于测量功能。在初始开始进行CCA和/或eCCA检测时，假定周围没有发送信息的节点存在，较远距离的节点发送的信息这里忽略不计。
如图17所示，UE1、UE2和UE3在第一个CCA和/或eCCA期进行能量检测，由于周围没有其他节点发送信息或是其他节点都处于静默状态，这三个UE都在特定的非授权载波上执行CCA，只有UE1根据自身周围的干扰状况判断信道此时为空闲状态，发送了一个占用信号。UE2和UE3在检测周围信号强度情况时，认为信道处于忙的状态，从而继续进行CCA和/或eCCA检测。在下一个CCA和/或eCCA期，继续执行CCA和/或eCCA检测的UE2和UE3再次判断周围信号强度情况，并解析已发占用信号，获知UE1正在发送占用信号，此时可以根据UE1发送功率和UE2和UE3接收功率的比值获知他们之间的距离。进一步根据占用信号中携带的信息(如组标号、小区标识、运营商标识)，判断是否是本组中的UE发送的占用信号，而抉择是否发送占用信号，从而屏蔽周围隐藏节点。在第2个CCA和/或eCCA期，只有UE2检测和解析正确特定非授权载波上发送的占用信号是本组中的UE1发送的，且距离较远，需要发送一个占用信号来屏蔽到周围隐藏节点。UE3检测和解析失败，所以需要继续执行CCA和/或eCCA检测。
实施例六：
图18是根据本发明实施例六的占用信号按照各种规则满足管制要求的示意图。
为了满足在非授权载波上发送的信号必须占到发送带宽的80％以上的管制要求，如图18所示的，可以通过下述几种规则来实现管制要求。
规则一：占用信号在频域上简单的重复。
规则二：频域上从低到高的顺序依次发送预先指定的占用信号，在剩余频域资源上发送按照组标识、UE ID、小区ID、运营商标识和同频复用指示或是它们的组合进行加扰的占用信号序列。
规则三：修改频域上子载波间隔大小。如子载波间隔可以为1.25kHz、2.5kHz、3.75kHz、5kHz、7.5kHz、10kHz、15kHz、20kHz、30kHz、60kHz、120kHz等。
规则四：在带宽频域资源的两端发送占用信号，中间的频域资源上不发送指定序列或是空置出来用于发送数据等其他信息或是什么都不发。
具体到本实施例，这里发送的占用信号可以为不携带任何有用信息的信号或是用于PSS/SSS、SRS或Preamble等信号或信道。以Preamble序列为例说明，Preamble在频域上占用6个RB，一个RB中有12个子载波，通常情况下，一个子载波间隔为15kHz，不能满足占用80％信道带宽的要求。基于此，修改子载波间隔，使得满足占用的带宽为发送带宽的80％，如图18(c)所示。根据目前子载波间隔的可用取值1.25kHz、2.5kHz、3.75kHz、5kHz、7.5kHz、10kHz、15kHz、20kHz、30kHz、60kHz、120kHz等，可以根据实际发送占用信号所需带宽要求而灵活进行更改子载波间隔。
规则一比较简单，就是在执行CCA成功后的符号上发送占用信号，如果占用信号在频域上只占一部分资源的话，则按照方法一在频域上进行简单的重复占用信号，使得满足占用的带宽为发送带宽的80％，图18(a)所示。
规则二，就是采用发送占用序列加扰方法。对于原始待发送的占用信号频域不满占用80％要求的情况，通过在剩余频域资源上发送用组标识、Cell ID、运营商标识或是暗含指示的标识加扰原始序列方法满足占用的带宽为发送带宽的80％的要求，图18(b)所示。
规则四是通过在频域资源两端的位置发送占用信号以满足占用信号占带宽80％的要求。也就是说，我们认为总带宽频域资源上，两端发送占用信号占用的频域资源为发送带宽的20％以下，则认为信道占用情况是满足80％以上要求的。根据频域资源上中间的空白和占用信号间的不同组合，会产生不同的图样。具体到图18(d)所示，占用信号本身可以采用空白方式发送，也可以在发送占用信道的部分RE上发送指示信息、信令或是数据，具体的占用指示信息和数据是按照时域各占一半或是频域各占一半或是数据占满整个占用信号资源或是其他规则可视情况而定。进一步的，中间的空余资源可以用于PUSCH资源或是数据传输。如果采用规则四，可以使非授权载波资源频域资源得到更好的利用。
实施例七：
对于目前LTE-U，终端侧和/或基站侧在执行CCA和/或eCCA检测时，都是基于整个频域带宽上进行信道空闲检测。这种在整个频域资源上执行CCA和/或eCCA检测的方式，假如终端或是基站检测信道空闲，便会在竞争到的整个非授权载波资源上进行数据传输。这样会 导致资源复用率低。
而本发明中的方案，则主要是：首先，引入组的概念，通过对终端或是基站以组的形式进行划分。其次，使不同组的UE组或是不同组的基站组在频域上不同的频域资源中执行对应的CCA和/或eCCA检测。然后，根据CCA和/或eCCA检测结果，如果不同组的UE组或是不同组的基站组均检测到信道空闲，则组内的UE或是基站就可以一起复用在对应频域位置上检测到空闲的非授权载波资源了。该方案，不仅使不同组的UE组或是基站组之间在进行信道空闲感知时就规避了彼此间的干扰，还可以使组内UE或是基站一起复用竞争到的资源，使资源在很大程度上得到了复用。下面将在本实施例中详细进行说明。
图19是根据本发明实施例的CCA和/或eCCA资源或者数据资源的示意图。
本实施例主要是说明UE对预先配置给该UE所属的组的特定的非授权载波或某一非授权载波中的预先配置给该UE所属的组的部分频域资源中进行CCA和/或eCCA检测，并进行占用信号发送的处理的。
下面从CCA和/或eCCA检测图样、占用信号的发送图样，发送数据的图样方面来进行说明：
CCA和/或eCCA检测图样可以有两种，分别是按频域上频分的方式或占用整个非授权载波资源的方式，具体而言，一种是预先配置给该组终端的CCA资源或eCCA资源，一种是对应于整个非授权载波带宽资源的CCA资源或eCCA资源。其中，预先配置的CCA资源或eCCA资源可以是特定位置上的资源，可以是奇数位置上的资源或偶数位置上的资源等。并且，配置给每个组的CCA和/或eCCA资源可以是不同的，可以为不同的组配置不同位置上的资源(如上述的可以按奇数偶数配置，还可以分段配置，当然也可以按等间隔和/或不等间隔方式配置)。举例说明不同组在执行CCA和/或eCCA检测的图样，假设：非授权频谱系统带宽为20MHz(20MHz系统带宽频域上等同于100个PRB或等同于1200个子载波)，有3组不同的UE组(即，第一组UE、第二组UE和第三组UE和第四组UE)。通过规则：(频域上PRB号)Mod(总的UE组数目)，使得在频域上100个PRB模3得到0，1，2的对应资源依次分配给第一组UE、第二组UE和第三组UE进行CCA或eCCA检测。
占用信号的发送图样也可以有两种，分别是按频域上频分的方式或占用整个非授权载波资源的方式，具体而言，一种是在预先配置的资源上发送占用信号，一种是在整个非授权载波上发送占用信号，并且，该预先配置的资源可以是特定位置上的非授权载波带宽资源，可以是奇数位置上的资源或偶数位置上的资源等。具体配置方式同上。
发送数据的图样也可以有两种，分别是按频域上频分的方式或占用整个非授权载波资源的方式，具体而言，一种是在预先配置的资源上发送数据，一种是在整个非授权载波上发送数据，并且，该预先配置的资源可以是特定位置上的非授权载波带宽资源，可以是奇数位置上的资源或偶数位置上的资源等。具体配置方式同上。
其中，上述图样的配置方式可以有多种，如前面所描述的，对于终端组来说，可以由基 站配置，也可以由不同的终端组之间协商。对于基站组来说，可以是不同的基站组之间进行协商来确定。
从上述内容可知，CCA和/或eCCA检测图样有两种，占用信号的发送图样有两种，发送数据的图样有两种，不同类型的图样之间是可以自由组合的，共有八种组合方式，包括：1)在预先配置的资源上进行CCA和/或eCCA检测，在预先配置的资源上发送占用信号，在预先配置的资源上发送数据；2)在预先配置资源上进行CCA和/或eCCA检测，在预先配置的资源上发送占用信号，在整个非授权载波资源上发送数据；3)在预先配置的资源上进行CCA和/或eCCA检测，在整个非授权载波资源上发送占用信号，在预先配置的资源上发送数据；4)在预先配置的资源上进行CCA和/或eCCA检测，在整个非授权载波资源上发送占用信号，在整个非授权载波资源上发送数据；5)在整个非授权载波资源上进行CCA和/或eCCA检测，在预先配置的资源上发送占用信号，在预先配置的资源上发送数据；6)在整个非授权载波资源上进行CCA和/或eCCA检测，在预先配置的资源上发送占用信号，在整个非授权载波资源上发送数据；7)在整个非授权载波资源上进行CCA和/或eCCA检测，在整个非授权载波资源上发送占用信号，在预先配置的资源上发送数据；8)在整个非授权载波资源上进行CCA和/或eCCA检测，在整个非授权载波资源上发送占用信号，在整个非授权载波资源上发送数据。
下面针对三组UE组之间如何避免干扰来对本发明进行说明，假如同一个组指示的是UE组，如图19可知，第一组UE、第二组UE和第三组UE通过基站侧通知其在频域上执行CCA和/或eCCA检测的频域资源位置，即频域上PRB号与总UE组数模的结果为0表示第三组UE组在该PRB上执行CCA和/或eCCA检测，同理模的结果为1则表示对应PRB资源分配给第一组UE组，模的结果为2则表示对应的PRB资源分配给第二组UE组。
其中：第一组UE和/或第二组UE和/或第三组UE可能是来自同一小区中的UE，也可能是来自于同一运营商不同小区中的UE，又或者，可能是来自于不同运营商不同小区中的UE。
第一组UE、第二组UE和第三组UE在各自的资源上进行CCA和/或eCCA检测，如果第一组UE在分配给自身的资源中执行CCA和/或eCCA检测成功(FBE下，只需要执行一次CCA，如果检测到空闲就算作执行CCA检测成功；LBE下，站点执行eCCA检测直到随机回退值为零，如果检测到空闲就算作执行CCA检测成功)，则立刻发送占用信号。而如果第二组UE在分配给自身的资源中执行CCA和/或eCCA检测成功，则同样在对应资源上发送占用信号。同理，第三组也在分配给自身的资源中执行CCA和/或eCCA检测成功，则同样在对应资源上发送占用信号。因为这三组UE在频域上通过频分的方式，分别在各自的资源上进行检测和占用信号的发送，因此彼此间也不会出现干扰。
其中，在各自分配资源上检测信道空闲且已发送占用信号的UE可以在发送占用信号后第一个符号位置或是第一个子帧位置开始按照与执行CCA和/或eCCA检测的资源位置一致的资源上进行复用或是按照预调度时配置的资源上复用。对于不同组UE在与执行CCA和/或eCCA检测的资源位置一致的资源进行多用户复用时，组内复用UE的资源都是通过基站预调度或是 基站间协商好的或是组内UE自主协商。
或者，第一组UE、第二组UE和第三组UE在各自的资源上进行CCA和/或eCCA检测，如果第一组UE在分配给自身的资源中执行CCA和/或eCCA检测成功，则立刻发送占用信号在整个带宽。而如果第二组UE在分配给自身的资源中执行CCA和/或eCCA检测成功，则同样在对应资源上发送占用信号在整个带宽。第三组UE同理。当第一组UE，或第二组UE或第三组UE执行CCA和/或eCCA检测未成功时，其应该接收整个带宽中的占用信号，并解析。如果解析后，认为可以进行资源复用，则从发送占用信号后第一个符号位置或是第一个子帧位置开始按照与执行CCA和/或eCCA检测的资源位置一致的资源上进行复用或是按照预调度时配置的资源上复用。
同理，图19中第一组、第二组和第三组也可以是基站。对于基站侧，第一组基站、第二组基站和第三组基站按照事先配置的位置，如图19所示。这三组基站在对应的资源位置上执行CCA和/或eCCA检测，如果检测到信道空闲，则立刻发送占用信号。和终端侧一样，基站可以按照与执行CCA和/或eCCA检测的资源位置一致的资源上进行资源复用或是按照协商的资源进行复用。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
