Abstract
本发明公开了一种终端设备的扩展使用方法、终端设备、网络设备及计算机存储介质，其中方法包括：向网络侧发送时频资源申请信息；接收所述网络侧为所述终端设备分配的时频资源，基于所述时频资源进行非基站通信业务。
Description
本发明涉及信息处理技术领域，尤其涉及一种终端设备的扩展使用方法、终端设备、网络设备及计算机存储介质。
授权频谱属于独占性频谱，即一般仅用于特定的通信技术使用，比如现在运营商使用的GSM900MHz频谱等仅能用于运营商的GSM业务使用。授权频谱的这种使用方式，导致频谱的利用率跟网络覆盖下的用户数量及活跃情况有关，如用户不多或用户活跃不强或时间分布比较集中等因素都会导致运营商频谱的利用率不高，频谱资源浪费。
此外，随着智能终端以及具备通信功能的特殊终端的快速发展，终端具备的功能也越来越强大，终端对周围环境的感知也渐渐成为迫切的需求。因此如何充分利用终端现有的通信能力以及空闲频谱实现非基站通信业务(比如环境探测)是一个可能的研究点和突破点。

为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种终端设备的扩展使用方法，应用于终端设备，如图1所示，所述方法包括：
步骤101：向网络侧发送时频资源申请信息；
步骤102：接收所述网络侧为所述终端设备分配的时频资源，基于所述时频资源进行非基站通信业务。
这里，所述终端设备可以为用户设备(UE)，具体的可以为移动通信网络中的用户设备。
本实施例提供的方案，主要用于终端设备向网络侧申请小区时频资源，该时频资源用于非基站通信类业务；相应的，网络侧动态衡量小区负载及对后续负载变化等进行预测，在满足一定条件后为终端调度一定的时频资源用于终端的环境探测等业务应用。
其中，所述非基站通信类业务可以为环境探测等业务。当然，还可以有其他业务，只是本实施例中不进行穷举。需要理解的是，环境探测等非基站通信类业务指终端利用自身已具备的通信收发功能如GSM/LTE/5G等来探测周围环境信息，如终端向周围测距来识别障碍物，或者识别周围的识别码进行导航及获取信息等应用。
所述方法还包括：
当分配的所述时频资源不适合进行非基站通信业务时，与所述网络侧进行协商重新获取更新后的时频资源、或者、断开连接。
也就是说，网络侧实时监测小区内的干扰情况或终端监测自身干扰情况等信息，在不适合继续进行非基站通信业务的情况下，与网络协商重新分配资源或断开连接。
下面可以分别针对终端设备在空闲态以及在连接态两种情况进行处理说明：
第一种场景、终端设备在空闲态下的授权频谱扩展使用方案：
其中，所述向网络侧发送时频资源申请信息，包括：
当所述终端设备处于空闲态时，基于所述终端设备的通信能力生成并向网络侧发送时频资源申请信息；其中，所述通信能力至少包括所述终端设备支持的通信制式以及通信频段。
本场景中，假设常规终端为UE，环境探测终端为UE1。当终端处于空闲态时，终端UE1依据自身情况尝试向网络发起近距离环境感知时频资源申请，该申请可以基于终端UE1支持的通信制式和通信频段等信息向网络申请。
网络衡量小区当前的用户负载情况，同时基于之前的用户负载经验判断资源的利用情况。之后网络给终端UE1分配特定的时频资源，用于终端UE1的环境探测。
比如，可以获取终端设备之前使用过的时频资源，首先针对该使用过的时频资源判断负载情况(也就是是否可以使用)，若可以，则可以直接为其分配以前使用过的时频资源；否则，可以选择当前负载最低的时频资源，将当前负载最低的时频资源分配给该终端设备。
进一步地，所述基于所述时频资源进行非基站通信业务，包括：
当所述时频资源为空闲状态时，所述终端设备采用第一功率进行发射；
当所述时频资源为非空闲状态时，所述终端设备采用第二功率进行发射；其中，所述第二功率低于第一功率。
具体来说，该分配的时频资源如为空闲状态，则终端UE1可以采用常规功率发射；如该分配的时频资源为占用状态且相关UE有较远距离，则网络仍可将该资源调度给UE1，但为避免对常规用户UE的干扰，需要限定UE1的发射功率等条件。
网络侧对以上资源的使用及调度等具有决策权，网络可以在任何时候视小区用户负载情况决定停止UE1对资源的使用或者对UE1收发状态进行调整。
比如，当所述终端设备与其他终端设备的距离小于预设门限值时，重新从网络侧获取更新后的时频资源、或基于网络侧控制停止使用所述时频资源；
或者，当所述终端设备检测到干扰超过预设干扰门限值时，将所述终端设备的时频资源的发射功率降低预设值、或者、停止在所述时频资源的发射并且向网络侧发送取消所述时频资源的授权的通知。
其中，所述干扰门限值可以根据实际情况进行设置，所述距离门限值也可以根据实际情况设置。
也就是说，当UE1和常规用户UE距离变近导致UE1潜在干扰常规用户UE或基站检测到较强的上行干扰等情况下，网络将为确保常规用户UE的性能而改变对UE1的授权策略，如改用新的时频资源或直接取消资源授权。
比如，参见图2，当UE1(也就是终端设备)处于空闲态的时候，若需要向网络侧(具体为图中的基站(BS))发送环境探测的时频资源请求，在该时频资源请求中可以包括有时长、发射功率等信息；相应的，BS基于时频资源请求，基于当前小区的负载、以及预期负载等情况，为UE1分配时频资源，其中，预期负载可以根据当前小区接入的UE的数量、业务等情况进行预测，则可以得知分配时频资源之后对应的小区负载将会成为什么情况，然后BS为UE1分配时频资源，其中可以包括有使用时长、频率以及传输功率限制(比如最大传输功率等等)；然后UE1可以向BS发送确认信息。
进一步地，如图2所示，还可以包括有当需要进行资源重分配的时候，BS基于检测得到的负载变化，为UE1调整并分配时频资源；然后UE1接收到BS重新分配的时频资源之后，向BS反馈确认消息。
第二种场景、如图3、4所示，在连接态下，终端具备的部分通信制式处于使用状态，此时如终端发起环境探测需求，则需同时兼顾目前正在进行的常规通信业务。
所述向网络侧发送时频资源申请信息，包括：
当所述终端设备处于连接态时，基于所述终端设备的通信能力生成并向网络侧发送时频资源申请信息；
其中，所述通信能力至少包括所述终端设备支持的通信制式、通信频段、期望时长以及发射功率。
其中，所述基于所述终端设备的通信能力生成并向网络侧发送时频资源申请信息，包括：
当所述终端设备支持在至少两个通信制式下工作的能力、或者所述终端设备支持一个通信制式中的至少两个通信频段中工作的能力时，向网络侧发送除当前常规通信业务所使用的时频资源之外的时频资源申请信息。
终端UE1依据自身情况尝试向网络发起近距离环境感知时频资源申请，该申请可以基于终端UE1支持的通信制式、通信频段、当前的常规通信制式及时频资源等信息向网络申请环境探测资源。该申请信息包含了终端支持的频段及通信制式信息、期望的时长信息、发射功率等。
如终端具备多个通信制式或一个通信制式里面的多个频段，同时终端具备多个制式或多个频段的同时工作能力，则终端可向网络按以下方式申 请资源：
终端申请除当前常规通信业务外的环境探测业务，以确保常规业务和环境探测业务采用的时频资源及终端收发通道不重叠。
如图3所示，网络衡量小区当前的用户负载情况，同时基于之前的用户负载经验判断资源的利用情况。之后网络给终端UE1分配特定的时频资源，用于终端UE1的环境探测。
所述基于所述时频资源进行非基站通信业务，包括：
当所述时频资源为空闲状态时，所述终端设备采用第一功率进行发射；
当所述时频资源为非空闲状态时，所述终端设备采用第二功率进行发射；其中，所述第二功率低于第一功率。
具体的，若该资源如为空闲状态，则终端UE1可以采用常规功率发射。
如该资源为占用状态且相关UE有较远距离，则网络仍可将该资源调度给UE1，但为避免对常规用户UE的干扰，需要限定UE1的发射功率等条件。
网络侧对以上资源的使用及调度等具有决策权，网络可以在任何时候视小区用户负载情况决定停止UE1对资源的使用或者对UE1收发状态进行调整。当所述终端设备与其他终端设备的距离小于预设距离门限值时，重新从网络侧获取更新后的时频资源、或基于网络侧控制停止使用所述时频资源。或者，当所述终端设备检测到干扰超过预设干扰门限值时，将所述终端设备的时频资源的发射功率降低预设值、或者、停止在所述时频资源的发射并且向网络侧发送取消所述时频资源的授权的通知。
比如，当UE1和常规用户UE距离变近导致UE1潜在干扰常规用户UE或基站检测到较强的上行干扰等情况下，网络将为确保常规用户UE的性能而改变对UE1的授权策略，如改用新的时频资源或直接取消资源授权。如下图4所示。
终端UE1的环境探测链路应避免对常规发射链路带来干扰，如UE1检测到较强的干扰，则应调低环境探测链路的发射功率，或停止发射且通知网络取消相应资源的授权。如图4所示。
可见，通过采用上述方案，就能够由网络侧为终端设备分配时频资源，以使得终端设备基于分配的时频资源进行非基站通信业务，比如环境探测等业务，如此，就能够充分利用授权频谱及终端自身硬件开展环境探测等非通信类业务，在提高频谱利用率的同时扩展了终端能力。
实施例二、
本发明实施例提供了一种终端设备的扩展使用方法，应用于网络设备，如图5所示，所述方法包括：
步骤501：接收终端设备发来的时频资源申请信息；其中，所述时频资源申请信息用于申请进行非基站通信业务的时频资源；
步骤502：基于所述终端设备所在小区的负载情况，为所述终端设备调度时频资源；
步骤503：向所述终端设备分配所述时频资源。
这里，所述终端设备可以为用户设备(UE)，具体的可以为移动通信网络中的用户设备。
本实施例提供的方案，主要用于终端设备向网络侧申请小区时频资源，该时频资源用于非基站通信类业务；相应的，网络侧动态衡量小区负载及对后续负载变化等进行预测，在满足一定条件后为终端调度一定的时频资源用于终端的环境探测等业务应用。
其中，所述非基站通信类业务可以为环境探测等业务。当然，还可以有其他业务，只是本实施例中不进行穷举。需要理解的是，环境探测等非基站通信类业务指终端利用自身已具备的通信收发功能如GSM/LTE/5G等来探测周围环境信息，如终端向周围测距来识别障碍物，或者识别周围的识别码进行导航及获取信息等应用。
所述方法还包括：
检测所述终端设备所在小区的干扰情况或检测所述终端设备的干扰情况；
当基于所述终端设备所在小区的干扰情况、和/或、根据终端设备的干扰情况，确定为所述终端设备分配的所述时频资源不适合进行非基站通信业务时，与所述终端设备进行协商为所述终端设备分配更新后的时频资源、或者、断开连接。
也就是说，网络侧实时监测小区内的干扰情况或终端监测自身干扰情况等信息，在不适合继续进行非基站通信业务的情况下，与网络协商重新分配资源或断开连接。
无论终端设备处于连接状态还是空闲状态，网络侧均需要衡量小区当前的用户负载情况，同时基于之前的用户负载经验判断资源的利用情况。之后网络给终端UE1分配特定的时频资源，用于终端UE1的环境探测。
所述基于所述时频资源进行非基站通信业务，包括：
当所述时频资源为空闲状态时，所述终端设备采用第一功率进行发射；
当所述时频资源为非空闲状态时，所述终端设备采用第二功率进行发射；其中，所述第二功率低于第一功率。
具体的，若该资源如为空闲状态，则终端UE1可以采用常规功率发射。
如该资源为占用状态且相关UE有较远距离，则网络仍可将该资源调度 给UE1，但为避免对常规用户UE的干扰，需要限定UE1的发射功率等条件。
网络侧对以上资源的使用及调度等具有决策权，网络可以在任何时候视小区用户负载情况决定停止UE1对资源的使用或者对UE1收发状态进行调整。当检测到所述终端设备与其他终端设备的距离小于预设门限值时，向终端设备分配更新后的时频资源、或控制终端设备停止使用所述时频资源。或者，当确定所述终端设备与其他终端设备的干扰值大于预设干扰门限值时，向终端设备分配更新后的时频资源、或控制终端设备停止使用所述时频资源。
比如，当UE1和常规用户UE距离变近导致UE1潜在干扰常规用户UE或基站检测到较强的上行干扰等情况下，网络将为确保常规用户UE的性能而改变对UE1的授权策略，如改用新的时频资源或直接取消资源授权。
终端UE1的环境探测链路应避免对常规发射链路带来干扰，如UE1检测到较强的干扰，则应调低环境探测链路的发射功率，或停止发射且通知网络取消相应资源的授权。
可见，通过采用上述方案，就能够由网络侧为终端设备分配时频资源，以使得终端设备基于分配的时频资源进行非基站通信业务，比如环境探测等业务，如此，就能够充分利用授权频谱及终端自身硬件开展环境探测等非通信类业务，在提高频谱利用率的同时扩展了终端能力。
实施例三、
本发明实施例提供了一种终端设备，如图6所示，所述方法包括：
第一通信单元61，向网络侧发送时频资源申请信息；接收所述网络侧为所述终端设备分配的时频资源；
第一处理单元62，基于所述时频资源进行非基站通信业务。
这里，所述终端设备可以为用户设备(UE)，具体的可以为移动通信网络中的用户设备。
本实施例提供的方案，主要用于终端设备向网络侧申请小区时频资源，该时频资源用于非基站通信类业务；相应的，网络侧动态衡量小区负载及对后续负载变化等进行预测，在满足一定条件后为终端调度一定的时频资源用于终端的环境探测等业务应用。

所述第一通信单元61，当分配的所述时频资源不适合进行非基站通信业务时，与所述网络侧进行协商重新获取更新后的时频资源、或者、断开连接。
也就是说，网络侧实时监测小区内的干扰情况或终端监测自身干扰情况等信息，在不适合继续进行非基站通信业务的情况下，与网络协商重新分配资源或断开连接。
下面可以分别针对终端设备在空闲态以及在连接态两种情况进行处理说明：
第一种场景、终端设备在空闲态下的授权频谱扩展使用方案：
其中，所述第一通信单元61，当所述终端设备处于空闲态时，基于所述终端设备的通信能力生成并向网络侧发送时频资源申请信息；其中，所述通信能力至少包括所述终端设备支持的通信制式以及通信频段。

进一步地，所述第一处理单元，当所述时频资源为空闲状态时，控制第一通信单元采用第一功率进行发射；当所述时频资源为非空闲状态时，控制第一通信单元采用第二功率进行发射；其中，所述第二功率低于第一功率。
具体来说，该分配的时频资源如为空闲状态，则终端UE1可以采用常规功率发射；如该分配的时频资源为占用状态且相关UE有较远距离，则网络仍可将该资源调度给UE1，但为避免对常规用户UE的干扰，需要限定UE1的发射功率等条件。
网络侧对以上资源的使用及调度等具有决策权，网络可以在任何时候视小区用户负载情况决定停止UE1对资源的使用或者对UE1收发状态进行调整。
比如，当所述终端设备与其他终端设备的距离小于预设门限值时，重 新从网络侧获取更新后的时频资源、或基于网络侧控制停止使用所述时频资源；
或者，当所述终端设备检测到干扰超过预设干扰门限值时，将所述终端设备的时频资源的发射功率降低预设值、或者、停止在所述时频资源的发射并且向网络侧发送取消所述时频资源的授权的通知。
其中，所述干扰门限值可以根据实际情况进行设置，所述距离门限值也可以根据实际情况设置。
也就是说，当UE1和常规用户UE距离变近导致UE1潜在干扰常规用户UE或基站检测到较强的上行干扰等情况下，网络将为确保常规用户UE的性能而改变对UE1的授权策略，如改用新的时频资源或直接取消资源授权。
比如，参见图2，当UE1(也就是终端设备)处于空闲态的时候，若需要向网络侧(具体为图中的基站(BS))发送环境探测的时频资源请求，在该时频资源请求中可以包括有时长、发射功率等信息；相应的，BS基于时频资源请求，基于当前小区的负载、以及预期负载等情况，为UE1分配时频资源，其中，预期负载可以根据当前小区接入的UE的数量、业务等情况进行预测，则可以得知分配时频资源之后对应的小区负载将会成为什么情况，然后BS为UE1分配时频资源，其中可以包括有使用时长、频率以及传输功率限制(比如最大传输功率等等)；然后UE1可以向BS发送确认信息。
进一步地，如图2所示，还可以包括有当需要进行资源重分配的时候，BS基于检测得到的负载变化，为UE1调整并分配时频资源；然后UE1接收到BS重新分配的时频资源之后，向BS反馈确认消息。
第二种场景、如图3、4所示，在连接态下，终端具备的部分通信制式处于使用状态，此时如终端发起环境探测需求，则需同时兼顾目前正在进行的常规通信业务。
所述第一通信单元61，当处于连接态时，基于通信能力生成并向网络侧发送时频资源申请信息；
其中，所述通信能力至少包括所述终端设备支持的通信制式、通信频段、期望时长以及发射功率。
其中，所述第一通信单元，当所述终端设备支持在至少两个通信制式下工作的能力、或者所述终端设备支持一个通信制式中的至少两个通信频段中工作的能力时，向网络侧发送除当前常规通信业务所使用的时频资源之外的时频资源申请信息。

如终端具备多个通信制式或一个通信制式里面的多个频段，同时终端具备多个制式或多个频段的同时工作能力，则终端可向网络按以下方式申请资源：
终端申请除当前常规通信业务外的环境探测业务，以确保常规业务和环境探测业务采用的时频资源及终端收发通道不重叠。
如图3所示，网络衡量小区当前的用户负载情况，同时基于之前的用户负载经验判断资源的利用情况。之后网络给终端UE1分配特定的时频资源，用于终端UE1的环境探测。

终端UE1的环境探测链路应避免对常规发射链路带来干扰，如UE1检测到较强的干扰，则应调低环境探测链路的发射功率，或停止发射且通知网络取消相应资源的授权。如图4所示。
可见，通过采用上述方案，就能够由网络侧为终端设备分配时频资源，以使得终端设备基于分配的时频资源进行非基站通信业务，比如环境探测等业务，如此，就能够充分利用授权频谱及终端自身硬件开展环境探测等 非通信类业务，在提高频谱利用率的同时扩展了终端能力。
