  • Wireless communication is based on spectrum, and spectrum is usually divided into two categories: licensed spectrum and unlicensed spectrum.
  • Licensed spectrum is widely used in mobile communications, satellite communications, radar detection and other application scenarios, and its use must be obtained. It can only be used with the authorization of the regulatory authority; the unlicensed spectrum is another way of using it, that is, the unlicensed spectrum can be used without the authorization of the regulatory authority, such as the commonly used WIFI, Bluetooth, etc. are all working on the unlicensed spectrum.

  • unlicensed spectrum For unlicensed spectrum, since everyone can use it, if it is not controlled, it will cause everyone to occupy the same spectrum resources at the same time and cause mutual interference, and even cannot be received by the receiver. Therefore, the use of unlicensed frequency bands can follow the principle of "first come, first served", that is, the terminal equipment needs to monitor whether there are other terminal equipment transmitting signals on the planned spectrum before transmitting signals (that is, the planned spectrum is occupied), If there is, it cannot be accessed, that is, it needs to find other target spectrums, and it can be occupied only when no other terminal equipment is transmitting signals.
  • the terminal device Before the terminal device transmits signals on the channel of the unlicensed spectrum, it needs to perform channel listening first. Only when the channel listening result is that the channel is idle, the terminal device can send the signal; if the terminal device is in the unlicensed spectrum channel The result of channel listening on the channel is that the channel is busy, and the terminal device cannot send signals.
  • the terminal device For the millimeter wave spectrum, the space propagation loss is large due to the high frequency. Therefore, as shown in Figure 2, the terminal device generally uses a narrow transmit beam to concentrate energy in the direction facing the receiving end for transmission to reduce propagation loss.

Therefore, it has significant characteristics with the low frequency band in the communication mode.

背景技术
低频段非授权频谱的接入方式是通过终端天线监测目标频谱的无线信号能量，来判断是否有其他终端占用。例如，低频段终端在占用的非授权频谱上以球面辐射的方式向空间进行信号发射，即，若某个终端占用所述非授权频谱，将导致其他终端在处于所述某个终端的任何方向上都会收到所述某个终端发射的信号，从而导致其他终端无法接入所述非授权频谱。

应理解，本申请实施例中网络/系统中具有通信功能的设备均可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备120和终端设备110，网络设备120和终端设备110可以为上文所述的设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要说明的是，上述涉及的终端设备可以采用非授权频谱的载波或授权频谱的载波进行数据传输。其中非授权频谱也可称为免授权频谱。
下面对非授权频谱和授权频谱进行介绍。
无线通信是建立在频谱的基础上，而频谱通常和划分为授权频谱和非授权频谱两大类，其中授权频谱被广泛用于移动通信、卫星通信、雷达探测等应用场景，且其使用必须得到监管部门的授权才可以使用；而非授权频谱则是与之相对的另外一种使用方式，也即在非授权频谱上面无需监管部门的授权即可使用这段频谱，比如通常所用到的 WIFI、蓝牙等都是工作在非授权频谱上。
例如，非授权频谱包括了频率比较低的频谱如2.4GHz等，也包括了频率高达几十GHz的毫米波频谱。而且，随着无人机等无线电终端的普及和应用，处于低频段的免授权频谱的使用变得非常拥塞，导致效率不高，因此越来越多的免授权业务及应用开始往毫米波等高频段迁移。
对于非授权频谱来说，由于所有人都可以使用，如果不加控制就会导致大家同时占用相同的频谱资源发射导致相互干扰，甚至无法被接收端接收。因此，免授权频段的使用可以遵循“先到先得”的原则，即终端设备在发射信号之前需要监测计划使用的频谱上面是否有其他终端设备在发射信号(即计划使用频谱被占用了)，如果有则不能接入，即需要寻找其他目标频谱，只有当没有其他终端设备在发射信号时，才可以占用。
换言之，终端设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该终端设备才能进行信号发送；如果终端设备在非授权频谱的信道上的信道侦听结果为信道忙，该终端设备不能进行信号发送。
如上所述，目前越来越多的业务开始往毫米波等高频段迁移。
而对于毫米波频谱来说，因频率很高导致空间传播损耗很大。因此，如图2所示，终端设备一般会采用窄发射波束来将能量集中到面向接收端的方向进行发射，以降低传播损耗。这是与低频段不同的，低频段终端设备则是采用向整个球面空间进行能量辐射的方式来进行信号的发射。因此在通信方式上跟低频段具有了显著的特点。
低频段非授权频谱的接入方式是通过终端设备天线监测目标频谱的无线信号能量，来判断是否有其他终端设备占用。例如，低频段终端在占用的非授权频谱上以球面辐射的方式向空间进行信号发射，即，若某个终端占用所述非授权频谱，将导致其他终端设备在处于所述某个终端的任何方向上都会收到所述某个终端设备发射的信号，从而导致其他终端设备无法接入所述非授权频谱。
但是，考虑到终端在高频段非授权频谱上发射信号的方式，不同于终端在低频段非授权频谱上发射信号的方式，因此，低频段非授权频谱的接入方式并不适用于低频段非授权频谱。
本申请实施例提供了一种适用于高频段非授权频谱的接入方式。
图3是本申请实施例提供的无线通信方法200的示意性流程图。所述方法200可以由终端设备执行。例如，如图1所示的终端设备。
如图3所示，所述方法200可包括：
S210，基于第一波束上的信号的强度确定所述第一波束是否为可用波束，所述第一波束为非授权频谱上的波束。
例如，若所述第一波束为可用波束，说明终端设备可以基于所述非授权频谱上的第一波束接入信道；若所述第一波束不是可用波束，说明终端设备不可以基于所述第一波束接入信道。
其中，所述第一波束上的信号可以是所述非授权频谱上其他终端发射的且被所述第一波束接收到的信号。所述第一波束上的信号也可称为所述第一波束上接收信号或所述第一波束上干扰信号。所述第一波束上的信号会对所述终端设备在所述第一波束上发送的信号产生干扰。为便于描述，下面将所述终端设备称为第二终端，将所述其他终端设备称为第一终端。
基于第一波束上的信号的强度，所述第二终端可以确定所述第一波束是否为可用波束，在所述第一波束为可用波束的情况下，所述第二终端可以基于所述第一波束进行信道接入，相当于，所述第一波束所在的非授权频谱可以同时支持多个终端设备的接入，由此，不仅能够实现在非授权频谱上进行无线通信，还能够提升非授权频谱的使用效率。
在本申请的一些实施例中，所述第一波束为所述非授权频谱上的第一方向上的波束。
例如，所述第一波束可以是所述非授权频谱上的，如图2所示的波束中的，任一方 向上的波束。
在本申请的一些实施例中，所述S210可包括：
若所述第一波束上的信号的强度，在第一持续时间内，大于第一阈值，确定所述第一波束不是可用波束；和/或
若在所述第一持续时间内，所述第一波束上的信号的平均强度，大于所述第一阈值，确定所述第一波束不是可用波束；和/或
若所述第一波束上的信号的强度，在第二持续时间内，小于或等于第二阈值，确定所述第一波束是可用波束；所述第二阈值小于或等于所述第一阈值；和/或
若在所述第二持续时间内，所述第一波束上的信号的平均强度，小于或等于第二阈值，确定所述第一波束是可用波束；和/或
若所述第一波束上的信号的强度，在第三持续时间内，小于或等于第三阈值，确定所述第一波束为可用波束中的优质备选波束；所述第三阈值小于或等于所述第二阈值；和/或
若在所述第三持续时间内，所述第一波束上的信号的平均强度，小于或等于第三阈值，确定所述第一波束为可用波束中的优质备选波束。
换言之，可以通过第一阈值、所述第二阈值以及所述第三阈值中的至少一个阈值，确定所述第一波束是否为可用波束。
需要说明的是，所述第一阈值、所述第二阈值以及所述第三阈值可以相等，即所述第一阈值、所述第二阈值以及所述第三阈值可以是同一个阈值。若所述第一波束上的信号的强度大于所述同一个阈值，说明存在占用所述非授权频上的所述第一波束的第一终端，此时，如果第二终端工作在所述第一波束上，即如果通过所述第一波束发送消息，所述第二终端和所述第一终端之间会存在干扰，影响通信质量；换言之，所述第二终端需要避免基于所述第一波束接入信道。与之相反，若所述第一波束上的信号的强度小于或等于所述同一个阈值，说明不存在占用所述非授权频谱上的第一波束的第一终端，此时，所述第二终端可以通过所述第一波束发送信息，即所述第二终端可以基于所述第一波束接入信道。
此外，所述第一持续时间、所述第二持续时间以及所述第三持续时间可以相同，也可以不同。所述第一持续时间、所述第二持续时间或所述第三持续时间可以是非负数。例如非负整数。
当然，所述第一阈值、所述第二阈值、所述第三阈值、所述第一持续时间、所述第二持续时间或所述第三持续时间可以是预设的，也可以是配置的，还可以是基于所述第二终端实现的数值。所述预设的可以是通标准定义或规定的；所述配置可以是其他设备配置的，例如，接入网设备或其他终端设备；所述配置可包括静态配置、半静态配置以及动态配置等。
在本申请的一些实施例中，所述方法200还可包括：
基于波束上的信号的强度，对所述非授权频谱上的可用波束进行排序。
例如，所述第二终端确定所述非授权频谱上的可用波束包括多个波束，所述第二终端可以按照信号的强度由高到低或由低到高的顺序对所述多个波束进行排序。
再如，若所述所述第一阈值、所述第二阈值以及所述第三阈值相等，且所述第二终端确定所述非授权频谱上的可用波束包括多个波束，所述第二终端可以按照信号的强度由高到低或由低到高的顺序对所述多个波束进行排序。
图4是本申请实施例提供的第一波束的示意性结构图。
如图4所示，所述第二终端在非授权频谱上可包括波束A、波束B以及波束C。
在确定可用波束的过程中，第二终端可以先使用一个接收波束(假设为A波束)来进行信号的检测，此时第二终端将接收到来自第一终端的发射信号，且信号强度持续时间T1(T1≥0)高于一定阈值X。此时第二终端认为当前信道被占用，且如果用A波束 发射则将对第一终端产生干扰，如果用A波束接收将受到来自第一终端的干扰。因此波束A不可用。
由此，所述第二终端可换另一个方向的波束(假设为B波束)来进一步做信号的检测，此时所述第二终端可能仍然会收到第一终端发送的信号，假设所述第二终端在波束B上收到的信号的强度持续T2(T2≥0)低于阈值Y(Y≤X)。此时，所述第二终端确定波束B为可用备选波束。
基于波束的频谱占用检测方式，与第二终端在整个空间辐射中的频谱占用的检测机制不同，具体而言，所述第二终端在某个方向上的波束检测到频谱占用实际并不意味着在其它方向也会跟占用频谱的第一终端产生干扰。因此通过调整波束指向，可以规避终端间的干扰。从而，提高了非授权频谱的利用率，及整体系统的吞吐量。
当然，所述第二终端也可以换另一个方向的波束(假设为C波束)来做信号的检测，此时收到的第一终端发送的信号的强度很弱，也即所述第二终端在波束C上收到的信号的强度持续T3(T3≥0)低于阈值Z(Z≤Y)，所述第二终端可以确定所述波束C为优质备选波束。
需要说明的是，阈值Y和阈值Z可以不进行区分，也即只有一个阈值，此时，所述“优质备选波束”实际可以划归到“可用备选波束”，并通过第二终端波束接收到的第一终端的发射信号的强度来对波束的干扰情况进行排序。第二终端完成目标频谱的检测后得到一组备选波束，所述第二终端可以在这些方向内进一步确定出后续使用的波束，即用于发射的波束。
在本申请的一些实施例中，所述非授权频谱上的波束包括至少一个波束组，所述至少一个波束组中的第一波束组，所述第一波束组包括所述第一波束。可选的，所述第一波束可以是所述第一波束组中位于中间位置的波束。可选的，所述第一波束可以是所述第一波束中的特定波束。
例如，可以按照以下方式确定所述第一波束是否为可用波束。
若所述第一波束上的信号的强度，在第四持续时间内，大于第四阈值，确定所述第一波束组内的波束均不是可用波束；和/或
若在所述第四持续时间内，所述第一波束上的信号的平均强度，大于所述第四阈值，确定所述第一波束组内的波束均不是可用波束；和/或
若所述第一波束上的信号的强度，在第五持续时间内，小于或等于第五阈值，确定所述第一波束是可用波束；所述第一波束组内的其他波束是否为可用波束基于所述其他波束上的信号的强度确定，所述第五阈值小于或等于所述第四阈值；和/或
若在所述第五持续时间内，所述第一波束上的信号的平均强度，小于或等于第五阈值，确定所述第一波束是可用波束；和/或
若所述第一波束上的信号的强度，在第六持续时间内，大于第六阈值，确定所述第一波束组内的波束均是可用波束；所述第六阈值小于或等于所述第五阈值；和/或
若在所述第六持续时间内，所述第一波束上的信号的平均强度，小于或等于第六阈值，确定所述第一波束组内的波束均是可用波束。
通过波束分组可以在所述第二终端有多个细分波束的情况下，加快干扰检测，从而与逐个波束检测相比，能够降低干扰检测或确定可用波束的耗时。
换言之，可以通过第四阈值、所述第五阈值以及所述第六阈值中的至少一个阈值，确定所述第四波束是否为可用波束。
需要说明的是，所述第四阈值、所述第五阈值以及所述第六阈值可以相等，即所述第四阈值、所述第五阈值以及所述第六阈值可以是同一个阈值。若所述第四波束上的信号的强度大于所述同一个阈值，说明存在占用所述非授权频上的所述第四波束的第四终端，此时，如果第五终端工作在所述第四波束上，即如果通过所述第四波束发送消息，所述第五终端和所述第四终端之间会存在干扰，影响通信质量；换言之，所述第五终端 需要避免基于所述第四波束接入信道。与之相反，若所述第四波束上的信号的强度小于或等于所述同一个阈值，说明不存在占用所述非授权频谱上的第四波束的第四终端，此时，所述第五终端可以通过所述第四波束发送信息，即所述第五终端可以基于所述第四波束接入信道。
此外，所述第四持续时间、所述第五持续时间以及所述第六持续时间可以相同，也可以不同。所述第四持续时间、所述第五持续时间或所述第六持续时间可以是非负数。例如非负整数。
当然，所述第四阈值、所述第五阈值、所述第六阈值、所述第四持续时间、所述第五持续时间或所述第六持续时间可以是预设的，也可以是配置的，还可以是基于所述第五终端实现的数值。所述预设的可以是通标准定义或规定的；所述配置可以是其他设备配置的，例如，接入网设备或其他终端设备；所述配置可包括静态配置、半静态配置以及动态配置等。
图5是本是本申请实施例提供的第一波束的示意性结构图。
如图5所示，所述第二终端在非授权频谱上可包括三个波束组，即{A1，A2，A3}波束组、{B1，B2，B3}波束组以及{C1，C2，C3}波束组。
在确定可用波束的过程中，第二终端选取各组合中间波束作为初始波束进行干扰检测，以{A1，A2，A3}波束组为例，选择A1进行初始波束的干扰检测。例如，所述第二终端检测到的信号的强度在一定时间T1内高于上文涉及的阈值X时，终端设备停止该波束组内其他波束(A2和A3)的干扰检测。再如，所述第二终端检测到的信号的强度在一定时间T2内低于上文涉及的阈值Y时，所述第二终端可进一步基于该组合内其他波束(A2和A3)进行干扰检测。再如，所述第二终端检测到的信号的强度在一定时间T3内低于上文涉及的阈值Z时，所述第二终端检可将该组合内其他波束(A2和A3)直接认定为可用备选波束。
以此类推，所述第二终端还可以继续对{B1，B2，B3}波束组以及{C1，C2，C3}波束组进行干扰检测。
在本申请的一些实施例中，所述第六阈值等于所述第五阈值；所述方法200还可包括：
确定用于确定所述其他波束是否为可用波束的判断方式。
例如，若上述阈值Y和上述阈值Z为同一阈值，所述第二终端确定用于确定波束组中除所述第一波束之外的其他波束是否为可用波束的判断方式。
在本申请的一些实施例中，所述方法200还可包括：
在所述非授权频谱上的可用波束中，确定用于发射数据的发射波束。
例如，所述第二终端在确定的多个可用波束中，将信号的强度最小的波束确定为用于发射数据的波束。
在本申请的一些实施例中，所述方法200还可包括：
周期性检测所述发射波束上的信号的强度；或
周期性检测所述非授权频谱上的每一个可用波束上的信号的强度。
在本申请的一些实施例中，所述方法200还可包括：
若所述发射波束上的信号的强度，在第七持续时间内，小于或等于第七阈值，调整用于发射数据的波束。
例如，所述第二终端在所述发射波束上发射数据，且周期性检测所述发射波束或每一个可用波束上的信号的强度。即对可能的潜在干扰进行监测，以避免可能存在的干扰。理由，由于所述第二终端发生移动或所述第二终端的波束的指向发生变化，此时所述发射波束上的信号的强度也可能发生变化。
换言之，所述第二终端每隔一定时间将监测所述非授权频谱及发射波束上的来自其他终端设备发射的信号的强度，当检测到的信号的强度高于一定阈值H后，所述第二终 端与所述其他终端设备之间的干扰将影响通信质量，即所述第二终端需要调整工作波束。例如，所述第二终端进行干扰检测并选出可用备选波束，用于后续的信号发射与接收。
图6示出了根据本申请实施例的无线通信方法300的示意性流程图。图7至图11是本申请提供的广播信号的示意性结构图。所述方法300可以由终端设备执行。例如，如图1所示的终端设备。下面结合图7至图11说明所述方法300。
如图6所示，所述方法300可包括：
S310，第一终端向第二终端发送广播信号，所述广播信号用于指示非授权频谱上已占用的第一时间长度。
如图7所示，所述广播信号指示的时间长度可以包括第一终端占用的时间长度L1。
通过所述广播信号，确定其他终端在非授权频谱上预定占用的时间长度，可以避免所述第二终端盲目的频谱占用情况检测，可以使得无序的非授权频谱的使用变得更加透明且可预期。换言之，通过所述广播信号，可以增强终端设备之间的信息沟通，能够避免因为缺少信息沟通导致的发生干扰的可能性比较频繁，以及波束选择及通信的成本过大的问题。此外，还可提升非授权频谱的使用效率。
在本申请的一些实施例中，所述广播信号用于指示至少一个终端设备在所述非授权频谱上分别占用的至少一个时间长度；和/或，所述广播信号用于指示所述至少一个终端设备在所述非授权频谱上的占用顺序；和/或，所述广播信号用于指示所述至少一个终端设备在所述非授权频谱上分别占用的时间的起始时刻。
在本申请的一些实施例中，所述方法300还可包括：
第二终端基于所述第一时间长度，确定期望在所述非授权频谱上占用的第二时间长度；所述第二终端发送请求信息，所述请求信息用于请求在所述非授权频谱上占用所述第二时间长度。可选的，所述第二时间长度位于所述第一时间长度之后。
简言之，所述第二终端确定期望在所述非授权频谱上占用的时间长度L2，并将所述时间长度L2通过广播的方式指示给所述第一终端。
换言之，所述第一终端接收到所述请求消息后，可将所述第二时间长度添加到所述广播信号指示的时间长度内。
例如，如图8所示，所述第一终端可以将所述第二终端期望在所述非授权频谱上占用的时间长度L2，添加至所述第一终端期望在所述非授权频谱上占用的时间长度L1。换言之，第二终端通过基于波束的频谱占用检测后，发现期望占用的非授权频谱已经被第一终端占用及占用的时间长度为L1。所述第二终端将自己预期占用的时间长度L2告知给所述第一终端，所述第一终端将第二终端的预期占用时间长度L2以广播方式通知其它终端。
再如，如图9所示，第三终端检测到第一终端正占用非授权频谱，第三终端同时读取到第一终端的占用时间长度L1以及第二终端的占用时间长度L2，如果第三终端在上述时间之后依然希望能够在这个波束方向占用非授权频谱，则第三终端也将其期望的占用时间长度L3通知第一终端。第一终端在广播消息中加入第三终端的时间长度L3。所述时间长度L3可以叠加在第二终端占用的时间长度L2之后。类似的，第四终端期望在所述非授权频谱上占用的时间长度L4，也可添加至所述时间长度L3。
在本申请的一些实施例中，第二终端周期性发送所述请求消息。
换言之，所述第一终端周期性接收所述请求消息。
通过周期性的发送所述请求消息，所述第二终端可以实时知道当前以及后续的频谱占用情况，能够使得无序的非授权频谱的使用变得更加透明且可预期。
在本申请的一些实施例中，所述方法300还可包括：
若周期性接收所述请求消息失败，取消所述广播信号指示的时间长度内的所述第二时间长度。
例如，第二终端的请求消息需要在间隔一定时间后周期性的告知此时占用频谱的第 一终端。如第一终端没有收到更新的请求消息，则之前接收的请求消息所请求的期望占用的时间长度L2将被取消，即所述广播信号指示的时间长度内不再包括所述时间长度L2。由此，所述第二终端在一定时间后选择了其他波束进行通信后，能够避免继续请求预期占用时间长度L2，避免对时间资源造成浪费。
在本申请的一些实施例中，所述第一终端可利用第三时间长度，替换所述广播信号指示的时间长度内的所述第二时间长度。
例如，如图10所示，利用第五终端期望在所述非授权频谱上占用的时间长度L5，替换所述时间长度L2。
在本申请的一些实施例中，所述第一终端可将所述广播信号指示的时间长度内的，所述第二时间长度之后的，时间长度的起始占用时间点，向前移动且移动的时间长度为所述第二时间长度。
例如，如图11所示，将所述时间长度L3和时间长度L4，整体向前移动且移动的时间长度为L2。
需要说明的是，当第一终端不再占用频谱时，后面的终端设备如第二终端在其预定的时间点占用这段频谱并进行通信。此时，所述第二终端作为当前占用所述非授权频谱的终端，可广播后续其他终端设备(例如，第三终端、第四终端以及第五终端等)预定的占用时间长度。
