下面结合图1至图5对本申请实施例的传输信息的方法进行说明，应理解，图1至图5是本申请实施例的传输信息的方法的示意性流程图，示出了该方法的详细的通信步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者图1至图5中的各种操作的变形。
此外，图1至图5中的各个步骤可以分别按照与图1至图5所呈现的不同的顺序来执行，并且有可能并非要执行图1至图5中的全部操作。
图1是根据本申请实施例的传输信息的方法100的示意性流程图，如图1所示，该方法100可以包括如下内容：
S110，第一设备使用第一波束和第一能量检测门限对免授权载波上的第一信道进行信道检测，以确定所述第一设备用于发送第一信息的第一时域资源是否可用；
S120，在所述第一时域资源可用的情况下，所述第一设备通过所述第一时域资源发送所述第一信息。
可选地，该第一设备可以为网络设备或者终端设备，因此，本申请实施例可以应用于免授权频谱上的网络设备或终端设备的信道接入过程。
在本申请实施例中，网络设备或终端设备的信道接入过程可以包括：通过检测信道是否处于空闲状态来判断该信道是否可用。
例如，网络设备和/或终端设备可以检测具有某一带宽(如，20MHz)的频域资源当前是否处于空闲状态，或者说，该频域资源是否被其他设备使用。
若该频域资源处于空闲状态，或者说，该频域资源未被其他设备使用(即信道空闲)，则网络设备和/或终端设备可以使用该频域资源进行通信，例如，进行上行传输或下行传输等。
若该频域资源不处于空闲状态，或者说，该频域资源已被其他设备使用(即信道被占用)，则网络设备和/或终端设备无法使用该频域资源。
具体而言，第一设备可以使用第一波束和第一能量检测门限对免授权载波上的第一信道进行信道检测，其中，所述第一能量检测门限为第一发射功率对应的能量检测门限，可选地，信道检测可以指第一设备可以收集一段时间内该第一信道上的信号能量，将能量值与该第一能量检测门限作比较，若该能量值大于或等于该第一能量检测门限，则可以认为信道被占用，从而可以确定用于发送第一信息的第一时域资源不可用，或者若该信号能量值小于该第一能量检测门限，则可以认为信道空闲，从而可以确定该第一时域资源可用，进一步地，可以在该第一时域资源上发送该第一信息。
可选地，该第一能量检测门限的大小可以根据该第一设备用于信号传输的发射功率的大小确定，例如，若发射功率越小，对应的能量检测门限可以越大，发射功率越大，对应的能量检测门限越小。
应理解，本申请实施例中，接收一个信号所使用的波束(或称接收波束)，可以理解为，接收一个信号所使用的空间域接收滤波器(Spatial domain reception filter)；相应地，发送一个信号所使用的波束(或称发送波束)，可以理解为，发送一个信号所使用的空间域传输滤波器(Spatial domain transmission filter)。对于采用相同的空间域发送滤波器发送的两个信号，可以称这两个信号相对于空间接收参数是准同址(Quasi-Co-Located，QCL)的。
可选地，在本申请实施例中，用于信道检测的第一波束(即接收波束中的一个或多个)和用于信号发送的第二波束(即发送波束中的一个或多个)可以为同一波束，或者也可以为不同的波束，本申请实施例对此不作限定。应理解，当用于信道检测的第一波束与用于信号发送的第二波束为不同的波束时，该第一波束的空间域覆盖范围与该第二波束的空间域覆盖范围至少部分重叠。
可选地，在本申请实施例中，所述第一波束对应的方向可以为全向，即第一设备可以进行全向的信道检测，然后可以进行方向性的数据传输。
应理解，在本申请实施例中，波束可以包括数据域的预编码处理，或者也可以包括模拟域的预编码处理，或者也可以包括数据域和模拟域的预编码处理，本申请实施例对此不作限定。
现有的通信系统中，可能会出现收发波束(beam)不完全匹配的情况，例如，在进行信道检测时，通信设备可以使用较粗方向的接收预编码，但发送信号时，通信设备可以使用较细方向的发送预编码来提高数据传输的波束增益(beamforming gain)，又例如，通信设备可以使用全向接收的方式进行信道检测，但使用带波束增益的方式进行信号发送等，从而可能导致收发波束不完全匹配的情况。
以网络设备和终端设备之间的下行传输为例，如图2所示，gNB1在为UE1提供服务前，可以基于发射功率P对应的能量检测门限，使用波束方向1对UE1所在方向的干扰进行信道检测，若发现信道空闲，则gNB1可以使用发射功率P和波束方向2对UE1进行数据传输。若波束方向2的beamforming gain(即波束增益)大于波束方向1的beamforming gain，会使得gNB1的数据传输范围超出了gNB1的信道检测范围，从而导致gNB1对UE1的数据传输会影响UE1周围的通信链路，例如，gNB2和UE2之间的通信链路。
基于上述技术问题，可选地，作为一个实施例，S120可以具体包括：
所述第一设备使用第二发射功率通过所述第一时域资源发送所述第一信息，其中，所述第二发射功率的大小和所述第一发射功率的大小不同，所述第一发射功率用于确定所述第一能量检测门限。
由上文描述可知，若信道检测范围小于数据传输范围，可能造成数据传输对其他通信链路的干扰，同时由于数据传输范围超出信道检测范围，可能存在有些信道上的资源是不可用的，因此，在该资源上进行数据传输，可能导致数据传输失败，影响数据传输的可靠性。
因此，在本申请实施例中，第一设备通过控制用于信号发送的第二发射功率和用于信道检测的第一发射功率，能够使得信道检测范围大于或等于数据传输范围，从而有利于避免数据传输对其他通信链路的干扰，同时也能够保证数据的有效传输。
应理解，在该实施例中，第一设备使用所述第二发射功率发送所述第一信息所使用的第二波束与使用所述第一发射功率对应的能量检测门限进行信道检测使用的第一波束可以相同，或者也可以不同，本申请实施例对此不作限定，只要通过控制第二发射功率和所述第一发射功率的关系，能够使得信道检测范围大于或等于数据传输范围即可。
需要说明的是，在本申请实施例中，一个波束对应的空间域覆盖范围可以由该波束的对应方向、覆盖角度和信号幅度(即波束增益)联合决定。若接收信号使用的第一波束对应的空间域覆盖范围和发送信号使用的第二波束对应的空间域覆盖范围完全相同， 可以认为该第一波束和第二波束相同；否则，可以认为该第一波束和该第二波束不同。其中，第一波束对应的空间域覆盖范围和第二波束对应的空间域覆盖范围完全相同可以指所述第一波束的对应方向、覆盖角度和波束增益与所述第二波束的对应方向、覆盖角度和波束增益都相同。可选地，若一个波束的覆盖角度越小，该波束对应的波束增益越大；反之，一个波束的覆盖角度越大，该波束对应的波束增益越小。
基于图2所示的技术问题，作为另一个实施例，S120可以具体包括：
所述第一设备使用第二波束通过所述第一时域资源发送所述第一信息，其中，所述第二波束和所述第一波束不同。
这里，第二波束和第一波束不同可以指第一波束和第二波束的覆盖角度和信号幅度中的至少一项不同，第一波束对应的方向和第二波束的对应方向至少部分重叠。第一设备使用与进行信道检测的第一波束不同的第二波束进行数据传输，从而所述第一设备可以通过控制所述第一波束和第二波束的空间域覆盖范围(例如，通过控制能量检测门限、信号发射功率、或第一波束和第二波束的选取等)使得信道检测范围至少覆盖数据传输范围，从而能够避免数据传输对其他通信链路的干扰。
应理解，在该实施例中，第一设备发送所述第一信息所使用的第二发射功率与所述第一设备进行信道检测所使用的能量检测门限对应的第一发射功率可以相等，或者也可以不等，本申请实施例对此不作限定，即在该实施例中，所述第一设备可以通过控制所述第一波束的空间域覆盖范围和所述第二波束的空间域覆盖范围以使信道检测范围大于或等于数据传输范围即可。
可选地，所述第一波束可以为第一波束集合中的波束，所述第二波束可以为第二波束集合中的波束，其中，所述第一波束集合可以为用于信道检测(或者信号接收)的波束的集合，所述第二波束集合可以为用于信号发送的波束的集合，所述第一波束集合和所述第二波束集合中至少一个波束不同。例如，第一波束集合和第二波束集合中包括的波束的个数不同，第一波束集合中包括N个波束，N为正整数，该N个波束对应不同的方向，第二波束集合中包括M个波束，M为正整数，该M个波束也对应不同的方向，第一波束集合中的N个波束与第二波束集合中的M个波束对应相同的方向和覆盖角度。假设M＝2*N，那么第一波束集合中的一个波束对应的方向和覆盖角度与第二波束集合中的两个波束联合对应的方向和覆盖角度相同，在这种情况下，可选地，第一波束集合中一个波束的波束增益小于第二波束集合中一个波束的波束增益。
可选地，在一些实施例中，所述第一设备也可以结合波束的信息和发射功率，控制信道检测范围至少覆盖数据传输范围。
例如，在所述第一波束和所述第二波束的信息(例如，对应方向，覆盖角度，信号幅度或称波束增益)确定的情况下，第一设备可以通过控制所述第一发射功率和所述第二发射功率的大小来控制信道检测范围和数据传输范围的大小。
应理解，本发明实施例中的数据发送可以是物理信道的发送或参考信号的发送，其中物理信道包括上行物理信道或下行物理信道，参考信号包括上行参考信号或下行参考信号，本申请对此并不限定。
可选地，在本申请实施例中，所述第一设备可以自行确定所述第一发射功率、所述第二发射功率、所述第一波束的信息和所述第二波束的信息，例如，所述第一设备可以先确定所述第一发射功率，然后再根据所述第一发射功率确定所述第二发射功率。或者，所述第一设备也可以先确定所述第二发射功率，然后再根据所述第二发射功率确定所述第一发射功率。或者，所述第一设备也可以同时确定所述第一发射功率和所述第二发射功率。
可选地，在本发明实施例中，对于第一波束、第二波束、第一发射功率和第二发射功率，第一设备可以通过其中的任意三个参数来确定第四个参数，本申请对此并不限制。例如，第一设备可以先确定第一波束、第二波束和第一发射功率，然后根据这三个参数 来确定用于数据传输的第二发射功率。又例如，第一设备可以先确定第一波束、第二波束和第二发射功率，然后根据这三个参数来确定第一发射功率，从而确定用于信道检测的第一发射功率对应的能量检测门限。
情况1：所述第一波束的对应方向和覆盖角度大于所述第二波束的对应方向和覆盖角度，且所述第一波束的信号幅度小于所述第二波束的信号幅度，或者说，第一波束的波束增益小于第二波束的波束增益，例如，图2所示的场景。
此情况下，所述第一设备可以使用第一波束和第一发射功率对应的第一能量检测门限进行信道检测，在信道检测成功(即信道检测结果为空闲)后，使用第二发射功率进行数据发送，其中，第二发射功率小于第一发射功率。
可选地，所述第一设备可以控制第一发射功率P1和第二发射功率P2的差值大于或等于特定的调整量X，从而能够使得数据传输范围落入信道检测范围内，即信道检测范围至少覆盖数据传输范围，其中，所述调整量X根据所述第二波束的波束增益大小与所述第一波束的波束增益大小的差值确定。
可选地，X可以为所述第一波束的波束增益和所述第二波束的波束增益的差值，例如，所述X可以为第一波束的波束增益和所述第二波束的波束增益的功率差值，或，所述X可以为第一波束的波束增益和所述第二波束的波束增益的能量差值，或者，所述X可以为第一波束的波束增益和所述第二波束的波束增益的信噪比差值。
可选地，在本申请实施例中，所述第一波束的波束增益也可以理解为基于第一波束对应的第一预编码获得的第一预编码增益，所述第二波束的波束增益也可以理解为基于第二波束对应的第二预编码获得的第二预编码增益。
相应地，所述X可以为第一预编码增益和第二预编码增益的功率差值，或，所述X可以为第一预编码增益和所述第二预编码增益的能量差值，或者，所述X可以为第一预编码增益和所述第二预编码增益的信噪比差值。
例如，假设第一设备计划使用第二波束和第二发射功率进行数据发送，以及计划使用第一波束进行信道检测，其中，第一波束对应的方向和覆盖角度包括(或者说，覆盖)第二波束对应的方向和覆盖角度，第一波束的波束增益为3dB，第二波束的波束增益为6dB，第二发射功率P2为17dBm，那么，第一设备确定第一波束的波束增益与第二波束的波束增益的差值X＝6dB-3dB＝3dB，相应地，第一发射功率P1应大于或等于第二发射功率P2与X的和，即P1应大于或等于17+3＝20dBm，即第一设备应根据不小于20dBm的第一发射功率来确定第一能量检测门限。
因此，在用于信道检测的第一波束的对应方向和覆盖角度大于用于数据传输的第二波束的对应方向和覆盖角度的情况下，如果第一波束的波束增益小于第二波束的波束增益，第一设备可以通过更大的第一发射功率进行信道检测，或第一设备可以通过更小的第二发射功率进行数据传输，从而使得数据传输范围小于或等于信道检测范围，进一步能够降低由于发送波束和接收波束不匹配对其他通信链路导致的干扰问题。
情况2：所述第一波束的对应方向和覆盖角度大于所述第二波束的对应方向和覆盖角度，且所述第一波束的信号幅度大于所述第二波束的信号幅度，或者说，第一波束的波束增益大于第二波束的波束增益，例如，图3所示的场景。
应理解，此情况下，第一波束可以包括多个波束，例如图3中第一波束包括3个波束，第二波束包括1个波束。
此情况下，可选地，所述第一设备可以使用第一波束和第一发射功率对应的第一能量检测门限进行信道检测，在信道检测成功(即信道检测结果为空闲)后，使用第二发射功率进行数据发送，其中，第二发射功率等于第一发射功率。
可选地，所述第一设备可以使用第一波束和第一发射功率对应的第一能量检测门限进行信道检测，在信道检测成功(即信道检测结果为空闲)后，使用第二发射功率进行数据发送，其中，第二发射功率大于第一发射功率。
可选地，所述第一设备可以控制第二发射功率P2和第一发射功率P1的差值小于或等于特定的调整量X，从而能够使得数据传输范围落入信道检测范围内，即信道检测范围至少覆盖数据传输范围，其中，所述调整量X根据所述第一波束的波束增益大小与所述第二波束的波束增益大小的差值确定。
可选地，X可以为所述第一波束的波束增益和所述第二波束的波束增益的差值，例如，所述X可以为第一波束的波束增益和所述第二波束的波束增益的功率差值，或，所述X可以为第一波束的波束增益和所述第二波束的波束增益的能量差值，或者，所述X可以为第一波束的波束增益和所述第二波束的波束增益的信噪比差值。
可选地，在本申请实施例中，所述第一波束的波束增益也可以理解为基于第一波束对应的第一预编码获得的第一预编码增益，所述第二波束的波束增益也可以理解为基于第二波束对应的第二预编码获得的第二预编码增益。
相应地，所述X可以为第一预编码增益和第二预编码增益的功率差值，或，所述X可以为第一预编码增益和所述第二预编码增益的能量差值，或者，所述X可以为第一预编码增益和所述第二预编码增益的信噪比差值。
例如，假设第一设备计划使用第二波束和第二发射功率进行数据发送，以及计划使用第一波束进行信道检测，其中，第一波束包括2个波束，第一波束包括的两个波束联合对应的方向和覆盖角度包括(或者说，覆盖)第二波束对应的方向和覆盖角度，第一波束包括的2个波束中每个波束的波束增益为6dB，第二波束的波束增益为3dB，第二发射功率P2为20dBm，那么，第一设备确定第一波束的波束增益与第二波束的波束增益的差值X＝6dB-3dB＝3dB，相应地，第一发射功率P1应大于或等于第二发射功率P2与X的差，即P1应大于或等于20-3＝17dBm，即第一设备应根据不小于17dBm的第一发射功率来确定第一能量检测门限。
因此，在用于信道检测的第一波束的对应方向和覆盖角度大于用于数据传输的第二波束的对应方向和覆盖角度的情况下，如果第一波束的波束增益大于第二波束的波束增益，第一设备可以通过更小的第一发射功率进行信道检测，或第一设备可以通过更大的第二发射功率进行数据传输，从而使得数据传输范围小于或等于信道检测范围，在能够降低由于发送波束和接收波束不匹配对其他通信链路导致的干扰的情况下提升数据传输的发射功率，保证数据传输的可靠性。
