具体实施方式
本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
以下对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：
1)终端，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
2)基站，又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，其包括各种通信制式中的基站，例如包括但不限于：传输接收点(Transmission Reception Point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)。此外，还可以包括Wifi接入点(Access Point，AP)等
3)免许可频谱，是指其使用不受无线电技术、运营企业和使用年限约束的的频谱。
4、侦听间隔，是指基于帧的设备(Frame Based Equipment,FBE)的侦听策略中，相邻两次侦听动作之间的时间间隔，侦听间隔包括信道占用时间(Channel Occupancy Time,简称COT)和空闲时间(IDle Period,简称IDP)。
5、竞争窗口，是指在基于负载的设备(Load Based Equipment，LBE)的侦听策略中，随机配置的空闲信道评测(Clear Channel Assessment,简称CCA)次数与单次CCA的时长的乘积。
在现有的许可辅助接入LTE(Licensed-Assisted Access LTE，简称LAA-LTE)***中，利用现有LTE(Long-term Evolution，长期演进)***中的载波聚合(Carrier Aggregation，CA)的配置和结构，以配置运营商许可频段上的载波进行通信为基础，配置免许可频段上的载波辅助许可频段上的载波进行通信，其设计需要遵循LBT的竞争机制。
在LBT的竞争机制中要求基站、终端等设备在发送信息之前先根据预设的侦听策略对信道进行空闲信道评测(Clear Channel Assessment,简称CCA)，若在CCA时间内接收到来自周围所有发送设备的总功率低于标准规定的固定CCA门限值，则认为成功抢占到信道，此时可以利用信道发送信号；反之认为信道被占用，则不发送信号，，在经过预设的时间间隔之后，再执行下一次的空闲信道评测，直到成功抢占到信道。
现有技术中，信道的侦听策略包括两种：一种为基于负载的设备(Load Based Equipment，简称LBE)的侦听策略，另一种为基于帧的设备(Frame Based Equipment,FBE)的侦听策略。
针对FBE的侦听策略，要求侦听和发送遵守一个固定帧结构，以图1为例，设备在CCA时间内执行信道侦听，当检测到信道被占用时，则在接下来的一个帧周期的COT内不发信息，反之则在COT内发送信息。其中，FBE侦听策略的一个帧周期的长度等于COT长度与IDP长度之和。现有技术中FBE侦听策略的帧周期长度是固定，即现有技术中FBE侦听策略的侦听间隔是固定不变。
针对LBE的侦听策略，现有技术设置有一个回退机制，当检测到信道被占用或基站结束信道占用之后都会在一个固定的时间间隔之后，进行下一次的空闲信道评测，其计数器初始化为一个随机整数，每隔CCA时长进行一次CCA，如果检测到信道空闲，则将计数器减一，直到计数器归零后再占用信道发送业务。LBE的竞争窗口等于该随机整数乘以CCA时长。在通信***中，LBE侦听策略的竞争窗口是固定不变的。
由此可见，现有技术中不论是LBE的侦听策略还是FBE的侦听策略，其信道侦听的CCA门限值、侦听间隔或竞争窗口均是固定不变的。然而在不同网络状态下，同频干扰大小是不同的，比如当竞争某一免许可频谱的设备数量较少时，该免许可频谱上的同频干扰较小，其相对于设备数量较多的情况对信号传输的影响较小，此时如果放宽对CCA门限值的限制，或者减小侦听间隔或竞争窗口，就能够使得设备更容易抢占到信道，从而提高免许可频谱的利用率。而如果始终保持CCA门限值、侦听间隔或竞争窗口固定不变，则无法充分利用免许可频谱，导致免许可频谱的利用率较低。尤其在新无线(New Radio，简称NR)***中引入了高频的情况下，由于高频同样存在大量的免许可频谱，且由于高频的免许可频谱采用的是波束成形的定向传输方式，在一定程度上减少了竞争碰撞的机会，并且，即使存在一定的干扰，***也可以正确的进行数据接收。而现有的许可辅助接入技术并未考虑到NR***的新特性，因此，基于上述原因需要对许可辅助接入技术中的CCA门限值、侦听间隔或竞争窗口进行重新设计。
图2为本申请实施例提供的一种应用场景示意图。图2中包括LAA控制实体00、基站10，基站11、基站12和基站13。其中，基站11、基站12、基站13所在的小区14、小区15、小区16包含在基站10的小区17内，即基站10为宏基站，基站11、基 站12和基站13为宏基站覆盖范围下的微基站。LAA控制实体00可以是独立的硬件实体，也可以是设置在宏基站10内的功能实体，本实施不对此做具体限定。实际执行过程中，LAA控制实体00根据小区17中各基站反馈的免许可频谱使用情况，确定竞争每个免许可频谱的设备数量。再根据竞争每个免许可频谱的设备数量，为每个免许可频谱配置相应的竞争参数，比如侦听策略(LBE的侦听策略或者FBE的侦听策略)、CCA门限值、侦听间隔或竞争窗口等。进一步的，再将每个免许可频谱对应的竞争参数发送给小区17中的基站，从而使得免许可频谱的竞争参数可以随着网络的变化而变化，比如当竞争某一免许可频谱的设备数量较少时，可以将该免许可频谱对应的CCA门限值设置的相对较大一些，将侦听间隔或竞争窗口设置的相对较小一些，这样就能有效提高该免许可频谱的利用率。当然为了清楚的阐述本申请的技术思想，图2中仅是以基站侧为例来做的示例性说明，但是本领域技术人员应该了解的是，上述技术方案在终端侧同样适用，其原理类似在这里不再赘述。
下面以基站侧为例结合具体的实施例对图2所示场景的执行方法进行详细的阐述，然而本领域技术人员应该了解的是，下述方法同样能够应用于终端侧的频谱竞争。
图3为本申请实施例提供的一种免许可频谱的竞争方法的信令流程图。在图3中默认采用LBE的侦听策略对免许可频谱进行侦听。如图3所示，该方法包括如下信令流程：
S1a、终端向其所属的基站发送免许可频谱的使用情况。
S1b、基站将其所处小区中免许可频谱的使用情况携带在频谱使用消息中发送给LAA控制实体。
S1c、其他设备将免许可频谱的使用情况发送给LAA控制实体。
S2、LAA控制实体根据免许可频谱的使用情况，确定免许可频谱的竞争参数。
S3、LAA控制实体将免许可频谱以及免许可频谱的竞争参数携带在第一通知消息中发送给基站。
S4、基站根据第一通知消息，将目标免许可频谱，以及目标免许可频谱的竞争参数发送给小区下的终端。
本实施例中涉及的其他设备包括但并不仅限于包括其他运营商的通信设备。
本实施例中，基站和其他设备实时的或周期性的将其所在区域的免许可频谱的使用情况携带在频谱使用消息中发送给LAA控制实体，其中，免许可频谱的使用情况中必要的包括使用过的免许可频谱，可选的，还可以包括免许可频谱的使用时间和时长，以及不能使用的免许可频谱。
具体的，LAA控制实体在接收到多个基站以及其他设备发送的频谱使用消息后，对各免许可频谱的使用情况进行统计，确定出竞争各免许可频谱的设备数量。进一步的，LAA控制实体再根据预先设定的设备数量与竞争参数之间的映射关系，为每个免许可频谱配置竞争参数，并将免许可频谱，以及免许可频谱的竞争参数，携带在第一通知消息中发送给基站，基站再将其参与竞争的目标免许可频谱，以及目标免许可频谱的竞争参数发送给基站所在小区下的终端。也就是说本实施例可以示例性的表述为免许可频谱的竞争参数与竞争免许可频谱的设备数量有关联。其中，免许可频谱的竞争参数中包括CCA门限值，可选的还可以包括侦听参数，其中侦听参数包括竞争窗口 或侦听间隔，侦听间隔包括COT和IDP，本实施例中示例性的采用LBE侦听策略，因此侦听参数中包括竞争窗口。
举例来说，当竞争免许可频谱的设备数量较少时，可以将该免许可频谱对应的CCA门限值设置的相对较大一些，将该免许可频谱的侦听间隔或竞争窗口设置的相对较小一些，这样就能有效的提高免许可频谱的利用率。当然这里仅为示例说明，而不是对上述映射关系的具体限定，实际上，上述映射关系可以根据需求具体设定，本实施例在这里不做限定。
可选的，当LAA控制实体接收到的频谱使用消息中包括基站使用免许可频谱的时间和时长，以及基站不能使用的免许可频谱的信息时，LAA控制实体根据基站使用免许可频谱的时间和时长，以及基站不能使用的免许可频谱的信息，确定出基站在各免许可频谱中的优先级，并将优先级信息携带在第一通知消息中发送给基站。比如，当基站a使用免许可频谱A的时间较多、时长较长时，则将基站a在免许可频谱A中的优先级设置的高一些，从而使得基站a能够较容易的竞争到免许可频谱A的使用权。再比如，基站a不能使用免许可频谱B，则免许可频谱B对应的基站优先级中就不包括基站a的优先级信息。当然这里仅为示例说明而不是对本发明的唯一限定。
可选的，本实施例中基站在接收到第一通知消息后，可能包括如下执行方式：
在一种可能的设计中，基站在接收到第一通知消息后，从第一通知消息所涉及的多个免许可频谱中随机确定一个免许可频谱作为目标免许可频谱。并根据第一通知消息中目标免许可频谱对应的竞争参数，竞争使用该目标免许可频谱。
在另一种可能的设计中，第一通知消息中还包括参与竞争每个免许可频谱的设备数量。在这种场景下，对于免许可频谱而言，参与竞争的设备数量越少，越容易抢占，且同频干扰也会相对较小，因此，基站在接收到第一通知消息后，优选的，根据第一通知消息中携带的每个免许可频谱对应的设备数量，从免许可频谱中选择对应设备数量最小，且可用的频谱作为目标免许可频谱。本实施例中，在确定目标免许可频谱之后可以通过两种方式竞争使用目标免许可频谱：一种方式是直接根据目标免许可频谱的竞争参数对目标免许可频谱进行竞争使用，在另一种方式中，基站先根据预先设定的设备数量与CCA门限值之间的映射关系，对目标免许可频谱的CCA门限值进行调整，再根据调整后的CCA门限值和第一通知消息中携带的竞争窗口竞争使用目标免许可频谱。比如，当目标免许可频谱对应的设备数量低于预设的数量时，可以将目标免许可频谱在第一通知消息中对应的CCA门限值增大，具体增大的数值与取决于设备数量与预设数量之间的偏离程度。这样就能在确保正常传输的前提下，提高抢占成功的概率，从而达到提高免许可频率利用率的目的。
在又一种可能的设计中，第一通知消息中包括基站在免许可频谱中的优先级信息，由于基站在免许可频谱中的优先级越高，越容易抢占到免许可频谱。因此，基站在接收到第一通知消息后，将其对应优先级最高的免许可频谱确定为目标免许可频谱。这样能够有效提高基站的抢占成功率。进一步的，在确定目标免许可频谱后，基站可以直接根据目标免许可频谱在第一通知消息中对应的竞争参数对目标免许可频谱进行竞争使用。可选的，基站也可以先根据预先设定的竞争优先级与CCA门限值之间的映射关系，对目标免许可频谱的CCA门限值进行调整，并根据调整后的CCA门限值竞争使 用目标免许可频谱。比如，当基站在目标免许可频谱中的竞争优先级高于预设等级时，可以将目标免许可频谱对应的CCA门限值增大，具体增大的数值与取决于基站在目标免许可频谱中的竞争优先级与预设等级之间的等级差。这样就能在确保正常传输的前提下，提高抢占成功的概率，从而达到提高免许可频率利用率的目的。
这里需要说明的是，本实施例仅是以LBE侦听策略为例进行的示例说明，但在实际应用中采用FBE侦听策略的情况与此类似，其不同在于在使用FBE侦听策略的情况下，免许可频谱的竞争参数中包括CCA门限值和侦听间隔，在这里不再赘述。
另外，由于本实施例中默认采用的LBE的侦听策略，因此，无需另外确定目标免许可频谱的侦听策略，并且本实施例中免许可频谱的竞争参数中包括侦听参数，即竞争窗口，因此，即使不是在默认侦听策略(LBE侦听策略或FBE侦听策略)的情况下，基站也可以根据具体的侦听参数，即竞争窗口或COT和IDP，以及目标免许可频谱的CCA门限值来对目标免许可频谱进行竞争使用。而在侦听策略不固定，免许可频谱的竞争参数中也不包括侦听参数的场景下，可选的，基站可以根据竞争目标免许可频谱的设备数量来确定目标免许可频谱的侦听策略，比如，当竞争目标免许可频谱的设备数量低于预设阈值时，采用LBE侦听策略，反之则采用FBE侦听策略。当然此处仅为示例说明，而不是本申请的唯一限定。
可选的，本实施例中，每个免许可频谱的侦听策略还可以由LAA控制实体配置后发送给基站。比如当某一免许可频谱对应的竞争设备的数量小于预设阈值时，则将该免许可频谱的侦听策略配置为LBE侦听策略，否则配置为FBE侦听策略，此与基站根据免许可频谱对应的设备数量确定侦听策略的方法类似，在这里不再赘述。
类似的，本实施例中免许可频谱的CCA门限值也可以由LAA控制实体根据竞争免许可频谱的设备数量进行配置，比如，当竞争免许可频谱的设备数量较少时，可以将该免许可频谱的CCA门限值设置的相对较大些，这样就能够增大该免许可频谱的竞争成功率，从而增大频谱利用率，至于设备数量与CCA门限值之间的映射关系，本实施例中不做限定。
可选的，在本实施例中，免许可频谱的竞争参数中还可以包括与侦听策略对应的侦听参数，比如，当免许可频谱的侦听策略为LBE侦听策略时，则竞争参数中包括竞争窗口，当免许可频谱的侦听策略为FBE侦听策略时，则竞争参数中包括侦听间隔。这里所涉及的竞争窗口或侦听间隔为LAA控制实体根据竞争该免许可频谱的设备数量确定的。当然，实际场景中，竞争参数中也可以不包括侦听参数，此时，基站根据第一通知消息中携带的免许可频谱的侦听策略、CCA门限值，以及现有技术中FBE侦听策略对应的侦听间隔，或者LBE侦听策略对应的竞争窗口竞争使用免许可频谱。
本实施例具体的竞争过程与现有技术类似，在这里不再赘述。
本实施例中，由于基站接收到的竞争参数是根据竞争免许可频谱的设备数量灵活设定的，因而使得频谱竞争更加能够适应网络的变化情况，比如当某一免许可频谱对应的竞争设备数量较少时，通过将该免许可频谱对应的CCA门限值设置的相对较大一些，这样该免许可频谱的抢占成功率就会有所提高，进而该免许可频谱的利用率也会相应的得到提高。
图4为本申请实施例提供的一种免许可频谱的竞争方法的流程图，在图4中默认采用LBE的侦听策略对免许可频谱进行侦听，如图4所示，本实施例在图3所示方案的基础上，包括如下步骤：
步骤201、基站向许可辅助接入LAA控制实体发送频谱使用消息，频谱使用消息中包括基站所处区域内的免许可频谱的使用情况。
步骤202、基站接收LAA控制实体发送的第一通知消息，第一通知消息中至少包括免许可频谱，以及免许可频谱的竞争参数，免许可频谱的竞争参数中包括CCA门限值和侦听参数。
步骤203、基站根据第一通知消息，竞争使用目标免许可频谱，目标免许可频谱为第一通知消息中包含的频谱。
其中，步骤201-步骤203的执行方式与图3所示实施例类似在这里不再赘述。
步骤204、确定是否成功竞争并使用目标免许可频谱，其中，若否，则执行步骤205，若是，则执行步骤206。
步骤205、基站确定目标免许可频谱是否是高频频谱，若是，则执行步骤208，否则，执行步骤207。
在本实施例中，考虑到NR***中引入了高频，由于在NR***中高频采用定向发送的方式发送数据，因此，在NR***中，不同方向上的频谱竞争互不影响，因此，当检测到目标免许可频谱为高频频谱时，即使保持当前的侦听参数的值不变，也能保证较高的频谱利用率。而当目标免许可频谱被占用，目标免许可频谱又不是高频频谱时，通过提高侦听参数的值，就能够提高目标免许可频谱的抢占成功率。实际应用中侦听参数包括侦听间隔或竞争窗口，而本实施例中默认采用LBE侦听策略，因此，侦听参数被具体为竞争窗口。即通过增大竞争窗口来提高频谱利用率。
类似的，当采用FBE侦听策略，侦听参数包括侦听间隔时，可以通过增大侦听间隔中COT或者COT和IDP的值来提高频谱利用率。
步骤206、基站根据本地消息和目标免许可频谱的侦听参数，确定下一次竞争使用目标免许可频谱时的侦听参数，其中，本地消息中包括无线链路失败(Radio Link Failure，简称RLF)的数目和确认(Acknowledgement，简称ACK)消息或者非确认(Non-Acknowledgement，简称NCK)消息。
其中，本实施例中所涉及的ACK消息和NCK消息是基站根据小区中多个终端反馈的ACK消息和/或NCK消息等效获得的。比如，在实际场景中，基站可以将小区下的多个终端，多个调度单元的反馈消息合并为一个等效的确认(Acknowledgement，简称ACK)消息或NCK消息，比如，当接收到的反馈消息中NCK的比例大于预设阈值X％时，则可以将反馈消息等效为NCK消息，反之等效为ACK消息。当然本实施例只是以等效NCK进行示例说明，实际情况中，也可以对ACK消息进行等效判断，其等效判断的方法与NCK类似，在这里不再赘述。
本实施例中，当基站的本地消息中包括NCK消息，且基站的RLF的数目小于预设阈值时，基站增大目标免许可频谱的侦听参数的值，下一次竞争使用该目标免许可频谱时，根据增大后的侦听参数进行竞争。
当基站的本地消息中包括ACK消息和/或基站的RLF的数目大于或等于预设阈值 时，基站维持目标免许可频谱的侦听参数不变或者减小，并将维持不变或者减小的侦听参数作为下一次竞争使用目标免许可频谱时的侦听参数。
这里需要说明的是：由于本实施例中默认采用LBE侦听策略，因此这里具体是通过改变竞争窗口的大小来改变侦听参数的值，而当实际中采用FBE侦听策略竞争目标面许可频谱时，通过改变侦听间隔中COT或者COT和IDP的值来改变侦听参数的值。但不论是改变COT的值还是改变COT和IDP的值，其均应保证IDP不低于COT的5％。
本实施例，通过对RLF的数目进行判断，能够确定出导致NCK的原因是否是由目标免许可频谱被占用所引起的，若是，则通过提高侦听参数值的方式来尽量避免冲突的发生，提高传输效果。
步骤207、基站增大目标免许可频谱的侦听参数的值，并将增大后的侦听参数作为下一次竞争使用目标免许可频谱的侦听参数。
步骤208、基站维持目标免许可频谱的侦听参数的值不变或减少，将维持不变或减少的侦听参数作为下一次竞争使用目标免许可频谱的侦听参数。本实施例，通过在抢占失败时对目标免许可频谱是否是高频频谱进行判断，并在判断目标免许可频谱不是高频时增加目标免许可频谱的侦听参数的值，提高了抢占目标免许可频谱的成功率，提高了频率的利用率。另外，当抢占成功时，通过对频谱占用时间内的反馈消息进行等效NCK和RLF数目的判断，当反馈消息等效为NCK，且RLF数目少于预设阈值时，增大目标免许可频谱的侦听参数的值，从而提高了抢占目标免许可频谱的成功率，提高了频率的利用率。
本申请实施例还提供的一种免许可频谱的竞争方法，在该方法中
LAA控制功能实体首先根据每个免许可频谱所对应的设备数量为每个免许可频谱配置对应的竞争参数，进一步的，再通过随机配置的方式为基站分配对应的免许可频谱，建立基站与免许可频谱之间的对应关系，进一步的，再将基站与免许可频谱之间的对应关系，以及免许可频谱的竞争参数携带在第一通知消息中发送给基站，将基站与免许可频谱之间的对应关系、免许可频谱与侦听策略、侦听策略对应的侦听间隔或竞争窗口发送给终端，以使基站和终端配合完成频谱侦听和信号传输。
本实施例中，基于竞争免许可频谱的设备数量，灵活设定免许可频谱的竞争参数，能够提高免许可频谱的抢占成功率和利用率。尤其当免许可频谱对应的竞争设备数量较少时，通过将免许可频谱对应的CCA门限值设置的相对较大一些，这样抢占成的概率就会增加，进而提高免许可频谱的利用率。
