技术领域

背景技术
共享频谱例如非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。非授权频段由多种技术(RATs)共用，因此，非授权频段在使用时必须符合一些规则，例如，先听后说(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等，以保证所有通信设备可以公平的使用该资源。
非授权频段的通信设备发送数据前需要先执行LBT，以对周围的节点进行功率检测(Energy Detection，ED)，当检测到的功率低于功率检测门限时认为信道为空(idle)，通信设备可以进行数据发送。反之，则认为信道为忙，通信设备不能进行数据发送。
高频通信中，基站和终端等通信设备将采用波束赋形技术发送和接收。针对波束赋形发送和接收，在共享频谱做功率检测时要考虑波束的方向性。然而，相关技术中并没有新定义该如何确定LBT时使用的功率检测门限，容易导致确定出的功率检测门限不准确，影响通信系统性能。

需要说明的是，本申请各个实施例中提到的波束(beam)可以通过波束信息来确定，该波束信息也可以称为：波束的标识信息、空间关系(spatial relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域接收滤波器(spatial domain reception filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、准共址(Quasi-Colocation，QCL)信息或QCL参数等。其中，下行波束信息通常可使用传输配置指示状态信息或QCL信息表示。上行波束信息通常可使用准共址信息或空间关系信息表示。
可选地，S202中通信设备根据监听波束覆盖发送波束的覆盖关系确定第一功率输出值包括：所述通信设备根据所述监听波束覆盖所述发送波束的覆盖关系确定传输簇；所述通信设备根据所述传输簇的EIRP确定所述第一功率输出值。
该实施例中，通信设备根据所述监听波束覆盖所述发送波束的覆盖关系确定传输簇可以包括如下1)和2)的至少之一：
1)若所述监听波束覆盖一个所述发送波束，则将一个所述发送波束上发 送的间隔均不大于X个时间单位的传输集合作为传输簇，X是正数，该时间单位可以是时隙(slot)、子时隙(sub-slot)、符号、微秒(us)等。
该例子例如，若一个LBT的监听波束只覆盖了一个发送波束，则传输簇是通信设备(如基站或者UE)在该发送波束上发送的任意间隔均不大于X的传输集合，X小于等于16us。也就是说，不同发送波束上的传输分别看作是不同的传输簇，无论这些发送波束上的传输之间的间隔是否小于等于X。
可选地，上述提到的传输集合，可以是通信设备在监听波束关联的一个COT内发送的传输集合。
2)若所述监听波束覆盖多个所述发送波束，则将多个所述发送波束上发送的间隔均不大于X个时间单位的传输集合作为传输簇，X是正数，该时间单位可以是slot、sub-slot、符号、微秒(us)等。
该例子例如，若一个LBT的监听波束覆盖多个发送波束，则传输簇是通信设备(如基站或者UE)在一个或者多个发送波束上发送的任意间隔均不大于X的传输集合，X小于等于16us。也就是说，不同的发送波束的传输间隔若小于等于X，则可以看作是一个传输簇。
可选地，上述提到的传输集合，可以是通信设备在监听波束关联的一个COT内发送的传输集合。
该实施例通过对不同发送波束的传输簇进行定义，有利于准确地得到每个监听波束对应的功率检测门限，避免不同通信设备采用不同的确定方式确定传输簇而造成的传输问题，提高通信系统性能。
本申请各个实施例中提到的所述监听波束覆盖所述发送波束可以包括如下1)至3)中的至少之一：
1)所述监听波束的主瓣和所述发送波束的主瓣的重叠部分超过所述监听波束的主瓣的y％。例如，y＝90，100或者其他正数值。
2)所述发送波束的Z dB波束宽度包含在所述监听波束的Z’dB波束宽度内。例如，Z和Z’＝3或者其他正数值。可选地，Z和Z’二者的取值还可以不一样。
3)所述监听波束在第一方向上的增益与所述发送波束在所述第一方向上的增益之比大于或等于Z1dB，Z1是正数。该第一方向可以是最大传输功率方向，还可以是最大传输功率方向之外的其他方向。
可以理解，上述1)至3)只是示例性介绍，实际上，还可以采用其他方式来确定所述监听波束覆盖所述发送波束的覆盖关系，或者是确定所述监听波束覆盖所述发送波束，本申请实施例并不以上述1)至3)为限。
在前文各个实施例的基础上，所述通信设备根据监听波束覆盖发送波束的覆盖关系确定第一功率输出值包括如下1)和2)至少之一：
1)若所述监听波束关联的信道占用时间(Channel Occupancy Time，COT)内包含一个传输簇，则将一个所述传输簇的平均EIRP作为所述第一功率输出值。该传输簇的确定方法可以参照前文实施例的介绍。
该传输簇可以包括一个或多个所述发送波束的传输，也即所述监听波束关联的COT内包含一个或多个所述发送波束的传输。
2)若所述监听波束关联的COT内包含多个传输簇，则将如下之一作为所述第一功率输出值：多个所述传输簇中每个所述传输簇的平均EIRP的平均值；多个所述传输簇中每个所述传输簇的平均EIRP的最大值。该传输簇的确定方法可以参照前文实施例的介绍。
每个传输簇可以包括一个或多个所述发送波束的传输，也即所述监听波束关联的COT内包含一个或多个所述发送波束的传输。
该例子例如，所述监听波束关联的COT内包含传输簇1和传输簇2，通信设备可以确定出传输簇1的平均EIRP为A，确定出传输簇2的平均EIRP为B，然后将A和B的平均值作为第一功率输出值；或者，将A和B中较大的一个值作为第一功率输出值。
该实施例中，每个所述传输簇的平均EIRP包括如下之一：每个所述传输簇包括的多个所述发送波束的EIRP的平均值；每个所述传输簇包括的多个所述发送波束的EIRP的加权平均值。
例如，传输簇1包括有发送波束1和发送波束2的传输，在确定传输簇 1的平均EIRP时，通信设备可以确定发送波束1的EIRP为C，确定发送波束2的EIRP为D；然后将C和D的平均值作为传输簇1的平均EIRP，或者，将C和D的加权平均值作为传输簇1的平均EIRP。
该例子中，加权的权重值可以根据监听波束覆盖发送波束的覆盖关系来确定，例如，监听波束的主瓣和发送波束1的主瓣的重叠部分为监听波束的主瓣的60％，监听波束的主瓣和发送波束2的主瓣的重叠部分为监听波束的主瓣的40％，则发送波束1对应的权重值可以为0.6，发送波束2对应的权重值可以为0.4，传输簇1的平均EIRP为(0.6C+0.4D)。可以理解，上述只是示例性介绍，实际应用中还可以采用其他的方法来确定加权的权重值。
与上述实施例并列，所述通信设备根据监听波束覆盖发送波束的覆盖关系确定第一功率输出值包括：若所述监听波束覆盖多个所述发送波束，则将多个所述发送波束的EIRP的加权平均值作为所述第一功率输出值。
该实施例例如，监听波束覆盖发送波束3和发送波束4，发送波束3的EIRP为E，发送波束4的EIRP为F，通信设备将E和F的加权平均值作为所述第一功率输出值。
该例子中，加权的权重值可以根据监听波束覆盖发送波束的覆盖关系来确定，例如，监听波束的主瓣和发送波束3的主瓣的重叠部分为监听波束的主瓣的70％，监听波束的主瓣和发送波束4的主瓣的重叠部分为监听波束的主瓣的30％，则发送波束3对应的权重值可以为0.7，发送波束4对应的权重值可以为0.3，第一功率输出值为(0.7E+0.3F)。可以理解，上述只是示例性介绍，实际应用中还可以采用其他的方法来确定加权的权重值。
可选地，前文各个实施例中，在一个所述监听波束覆盖一个所述发送波束的情况下，至少两个所述发送波束对应各自的所述功率检测门限。例如，若一个所述监听波束覆盖一个所述发送波束，则针对至少两个所述发送波束确定出的所述功率检测门限不同。
该实施例例如，若存在多个监听波束和多个发送波束，多个监听波束和多个发送波束是一一对应关系，若一个LBT的监听波束只覆盖了一个发送波 束，则针对不同发送波束的LBT的功率检测门限可以不同。
可选地，前文各个实施例提到的通信设备可以是网络侧设备(如基站)，所述方法还包括：所述网络侧设备发送COT的持续时间信息(COT duration)以及所述COT的持续时间信息对应的波束信息，所述波束信息用于终端确定是否能够共享所述COT。
该实施例中，基站可以基于波束信息指示COT的持续时间信息。即，基站除了指示COT的持续时间信息，还指示与该COT的持续时间信息相关联的监听波束的信息，下行发送波束或者上行发送波束等相关信息。
可选地，与上述实施例对应，前文各个实施例提到的通信设备还可以是终端，所述方法还包括：所述终端接收COT的持续时间信息以及所述COT的持续时间信息对应的波束信息；所述终端根据所述波束信息，所述COT的持续时间信息以及数据调度信息确定是否能够共享所述COT。
该实施例中，终端根据波束信息，COT的持续时间信息以及数据调度信息确定是否可以共享基站的COT。
可选地，上述两个实施例提到的波束信息可以包括如下至少之一：所述COT相关的所述监听波束的相关信息；下行波束的相关信息；上行波束的相关信息。
为详细说明本申请实施例提供的功率检测门限的确定方法、COT共享方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例中，若一个LBT的监听波束只覆盖一个发送波束(简称波束)，如图3所示，即通信设备针对每一个发送波束分别进行LBT(per-beam LBT)。在COT开始之前，基站或者UE针对每个发送波束分别做LBT。此时每个波束上的功率检测门限(EDT)可以根据该波束上的传输簇来计算。
若波束1(beam1)有一个传输簇，即该波束1上的多个传输之间的间隔(gap)小于X us，则第一功率输出值是这个传输簇内的平均(mean)EIRP，然后根据这个EIRP计算波束1上的EDT。
若波束2上有两个传输簇，即该波束2上的两个传输之间的间隔大于X us，则确定EDT的第一功率输出值是这两个传输簇的平均ERIP的平均值。依次类推。
需要说明的是，图3中是以时分复用(Time Division Multiplexing，TDM)的传输方式为示例，对于空分复用(Space Division Multiplexing，SDM)的传输方式上述方法同样适用。
另外，在图3中，COT内不同发送波束传输之间的LBT还可以省略。后续图4和图5中，COT内不同发送波束传输之间没有LBT。
该实施例中，由于不同的监听波束可以采用不同的第一功率输出值来进行LBT(取决于该监听波束上传输的传输簇的平均EIRP)，因此，per-beam LBT的方式可以针对不同的发送波束采用不同的EDT。
实施例二
该实施例中，若一个LBT的监听波束覆盖多于一个发送波束，如图4所示，一个监听波束(如图4左下角的扇形所示)覆盖3个发送波束。
在COT开始前，基站或者UE使用一个宽波束做LBT，该宽波束可以覆盖多个在COT内传输的发送波束，如图4中的波束1，波束2和波束3。其中波束1和波束2的传输中间的间隔小于X us，则这两个传输看作一个传输簇。波束3的传输和传输簇1之间的间隔大于X us，则看作另外一个传输簇。
因此，采用宽波束做LBT的时候，确定EDT的第一功率输出值是传输簇1的平均EIRP和传输簇2的平均EIRP的平均值。其中每个传输簇的平均EIRP是他们包含所有的发送波束的EIRP的平均值。
此外，若监听波束覆盖发送波束的覆盖关系如图5所示，此时第一功率输出值可以看作是三个发送波束的EIRP的加权平均值，该例子中可以不存在传输簇的概念，可以忽略图5中的传输簇1和传输簇2。
该例子中，每一个发送波束的权重可以通过监听波束覆盖发送波束的覆盖关系确定，例如发送波束和监听波束在某些方向上的功率比，或者发送波束和监听波束主瓣的重叠度等等，也可以通过其他影响发送波束功率的因素 确定。
可选地，图5中也可以用传输簇1的平均EIRP和传输簇2的平均EIRP的平均值来确定EDT的第一功率输出值，其中，每个传输簇的平均EIRP是他们包含所有的发送波束的EIRP的加权平均值。
例如，传输簇1的平均EIRP是发送波束1和发送波束2的EIRP的加权平均值。权重可以通过监听波束覆盖发送波束的覆盖关系确定，例如发送波束和监听波束在某些方向上的功率比，或者发送波束和监听波束主瓣的重叠度等等。也可以通过其他影响发送波束功率的因素确定。
可选地，实施例二的上述各个例子中，确定EDT的第一功率输出值还可以是监听波束覆盖的所有传输簇的平均EIRP的最大值，前文各个例子均以各个传输簇的平均EIRP的平均值为例进行说明。
实施例三
当基站在监听波束1上做LBT，且在该波束方向上向UE1发送下行信息，则UE1根据接收到的COT的持续时间信息，只能在监听波束1的覆盖范围内共享信道，即UE1只能在监听波束1的覆盖范围内共享基站的COT向基站发送上行信息。
若基站在多个波束做LBT，例如监听波束1，监听波束2和监听波束3，此时，虽然基站只在监听波束1的覆盖范围向UE1发送下行信息，但是UE1可以在监听波束1，监听波束2和监听波束3覆盖范围内共享基站的COT向基站发送上行信息。
因此，该实施例的核心思想是：基站将COT的持续时间信息与监听波束的相关信息一起发送给UE，则UE可以根据联合信息确定是否共享基站的COT。
例如，基站针对每个监听波束分别指示COT的持续时间信息，使得UE可以在各个监听波束的覆盖范围内共享基站的COT。在下行控制信息(Downlink Control Information，DCI)2_0中，增加波束信息指示域，该波束信息指示了基站做LBT的监听波束相关信息，或者基站进行DL传输的TCI  state信息或QCL信息，或者UE进行上行传输的TCI state信息或spatial relation信息。UE根据该波束信息，可以确定在哪些波束上可以共享基站的COT。
此外，DCI 2_0中可以按照传统方式对每个小区指示一个COT的持续时间信息，表示波束信息指示域中所指示的所有波束的COT的持续时间都一样。也可以扩展COT的持续时间信息指示域，分别指示波束信息指示域中所指示的每一个波束的COT的持续时间。
UE根据波束指示信息、COT的持续时间信息，以及数据调度信息，可以确定是否可以共享基站的COT进行上行传输。
如果基站指示的波束信息和数据调度信息中指示波束信息不一致，或者说UE从波束信息中得出的上行传输波束信息和数据调度信息中指示上行传输波束信息不一致，则UE自己发起COT(initiate COT)进行传输。否则，UE在对应的波束上共享基站的COT进行上行传输。
