调度请求发送方法、调度请求接收方法、终端和网络设备
相关申请的交叉引用
本申请主张在2019年7月11日在中国提交的中国专利申请号No.201910626768.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种调度请求发送方法、调度请求接收方法、终端和网络设备。
背景技术
在高频段通信***中，由于无线信号的波长较短，较容易发生信号传播被阻挡等情况，导致信号传播中断。如果采用相关技术中的无线链路重建，则耗时较长，因此引入了波束失败恢复机制。相关技术中的波束失败恢复(Beam failure recovery，BFR)机制包括以下四个步骤：
第一，波束失败检测(Beam failure detection)。终端在物理层对波束失败检测参考信号(beam failure detection reference signal)进行测量，并根据测量结果来判断是否发生波束失败事件。
第二，新的候选波束识别(New candidate beam identification)。终端物理层测量波束识别参考信号(beam identification Reference signal)，寻找新的候选波束(candidate beam)。本步骤不强制在beam failure event发生后，也可以在之前。
第三，传输波束失败恢复请求(Beam failure recovery request，BFRQ)信息。
第四，终端检测网络设备对波束失败恢复请求的响应(UE monitors gNB response for beam failure recovery request)。
在辅小区波束失败恢复(SCell BFR)过程中，可以通过调度请求(Scheduling Request，SR)触发网络设备为终端配置或者指示上行授权资源，在该上行授权资源上传输BFRQ信息。然而，相关技术中，满足SR的触发 条件后，终端将会周期性的发送SR，这将会导致SR的资源开销较大。
发明内容
本公开实施例提供一种调度请求发送方法、调度请求接收方法、终端和网络设备，以解决相关技术中，满足SR的触发条件后，周期性的发送SR，导致SR的资源开销较大问题。

第二方面，本公开实施例还提供一种调度请求接收方法，应用于网络设备，包括：
接收终端在满足第一触发条件的情况下，发送的调度请求SR；
在满足第二触发条件的情况下，停止所述SR的接收或跳过N次所述SR的接收，N为大于1的整数。
第三方面，本公开实施例还提供一种终端，包括：
发送模块，用于在满足第一触发条件的情况下，向网络设备发送调度请求SR；在满足第二触发条件的情况下，取消所述SR的发送或跳过N次SR的发送，N为大于1的整数。
第四方面，本公开实施例还提供一种网络设备，包括：
接收模块，用于接收终端在满足第一触发条件的情况下，发送的调度请求SR；在满足第二触发条件的情况下，停止所述SR的接收或跳过N次所述SR的接收，N为大于1的整数。
第五方面，本公开实施例还提供一种终端，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的程序，所述程序被所述处理器执行时实现上述调度请求发送方法中的步骤。
第六方面，本公开实施例还提供一种网络设备，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的程序，所述程序被所述处 理器执行时实现上述调度请求接收方法中的步骤。

本公开实施例，通过设置第二触发条件，在满足第二触发条件的情况下，取消所述SR的发送或跳过N次SR的发送。这样减少了SR的发送次数，从而降低了SR的资源开销。与此同时，降低了终端功耗，延长了终端的待机时长。

下面结合附图介绍本公开的实施例。本公开实施例提供的一种调度请求发送方法、调度请求接收方法、终端和网络设备可以应用于无线通信***中。该无线通信***可以为采用第五代(5 th generation，5G)***，或者演进型长期演进(Evolved Long Term Evolution，eLTE)***，或者后续演进通信***。
请参见图1，图1是本公开实施例可应用的一种网络***的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。上述网络设备12可以是5G基站，或者以后版本的基站，或者其他通信***中的基站，或者称之为节点B，演进节点B，或者发送接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
请参见图2，图2是本公开实施例提供的一种调度请求发送方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201，在满足第一触发条件的情况下，向网络设备发送调度请求SR；
步骤202，在满足第二触发条件的情况下，取消所述SR的发送或跳过N次SR的发送，N为大于1的整数。
上述SR可以用于触发网络设备配置或者指示上行授权资源，在该上行授权资源上可以传输BFRQ信息。上述N的大小可以根据实际需要进行设置， 在本实施例中，该N的大小可以通过协议约定，也可以由网络设备通知。
本公开实施例中，可以在发送波束失败事件时，触发SR和BFRQ信息，通过预先设置的第二触发条件限制SR的发送，例如，在满足第二触发条件时，可以取消SR的发送，也可以直接跳过N次SR的发送，N的大小可以根据实际需要进行设置，在此不做进一步的限定。
可选的，上述SR在生成后，处于待发送pending状态。在该pending状态下，终端可以对该SR进行发送。
本公开实施例，通过设置第二触发条件，在满足第二触发条件的情况下，取消所述SR的发送或跳过N次SR的发送。这样减少了SR的发送次数，从而降低了SR的资源开销。与此同时，降低了终端功耗，延长了终端的待机时长。
可选的，上述SR可以为专用于波束失败恢复的SR(以下称之为专用SR，即dedicated SR)或其他SR(以下称之为相关技术SR，即相关技术中的SR)。其中，专用SR用于通知网络设备将有BFRQ信息发送给网络设备，也即该专用SR用于触发网络设备指示的第一上行授权资源，该第一上行授权资源专用于传输BFRQ信息。相关技术SR可以用于通知网络设备存在待发送的其他上行信息，网络设备可以根据该相关技术SR为终端配置或指示第二上行授权资源，上述BFRQ信息可以与其他上行信息复用在该第二上行授权资源上进行传输。
可选的，在一实施例中，上述步骤201之后，该方法还包括：
在网络设备配置或指示的上行授权资源上，向所述网络设备发送BFRQ信息。
本实施例中，网络设备配置或指示的上行授权资源可以包括上述第一上行授权资源或最近可用的第二上行授权资源。可选的，该第二上行授权资源包括以下至少一项：
配置授权(configured grant)的上行授权资源；
动态授权(dynamic grant)的上行授权资源；
随机接入(Random Access，RA)过程中的上行授权资源。
可选的，该随机接入过程具体可以指2步随机接入过程或者4步随机接 入过程。对应的，第二上行授权资源指：2步随机接入(2-step RA)过程的PUSCH或者4步随机接入(4-step RA)过程的PUSCH。
进一步的，上述BFRQ信息可以由媒体接入控制控制元素(Medium Access Control Control Element，MAC CE)承载。
本实施例中，可以是不同的BFRQ信息在不同的MAC CE上，且一个MAC CE用于传输一个BFRQ信息的部分或全部信息，也可以是一个MAC CE传输多个或所有BFRQ信息。
进一步的，在一可选实施例中，在满足第二触发条件的情况下，所述方法还包括：
取消所述BFRQ信息的发送。
本公开实施例中，由于将第二触发条件设置为取消BFRQ信息发送的触发条件，从而可以减少BFRQ信息重复发送的次数。这样，可以进一步减少数据发送量，因此可以降低资源开销，降低终端功耗，延长终端的待机时长。
应理解，上述第一触发条件具体可以根据实际需要进行设置，例如在一可选实施例中，上述第一触发条件可以包括以下至少一项：
检测到发生波束失败；
检测到发生波束失败，且识别到新的波束；
存在待发送的波束失败恢复请求BFRQ信息，且不存在可用的上行资源发送所述待发送的BFRQ信息。
其中，所述检测到发生波束失败包括以下至少一项：
检测到小区发生波束失败；
检测到带宽部分(Bandwidth Part，BWP)发生波束失败；
检测到发送接收点TRP发生波束失败。
上述检测到发生波束失败，且识别到新的波束包括以下至少一项：
检测到小区发生波束失败，且在检测到波束失败的小区上识别到新的波束；
检测到带宽部分BWP发生波束失败，且在检测到波束失败的BWP上识别到新的波束；
检测到发送接收点TRP发生波束失败，且在检测到波束失败的TRP上识 别到新的波束。
本实施例中，终端可以测量波束失败检测参考信号(Beam Failure Detection Reference Signal，BFD RS)。根据测量结果判断在至少一个目标对象是否发生波束失败事件，该目标对象为小区、BWP或TRP。此外，终端可以通过测量用于新的候选波束识别的下行参考信号，确定发生波束失败的小区、BWP或TRP上是否找到新的波束。
本实施例中，存在待发送的BFRQ信息，且不存在可用的上行资源发送所述待发送的BFRQ信息具体可以理解为：当存在用于传输BFRQ信息的MAC CE(MAC CE for BFRQ)的情况下，没有用于新传输的物理上行共享信道(Physical uplink shared channel，PUSCH)资源，或者即使存在上行资源，但根据逻辑信道优先级关系，该MAC CE for BFRQ的优先级较低，而不能使用该上行资源。
进一步的，所述向网络设备发送调度请求SR之前，所述方法还包括：
在发生波束失败的情况下，触发第一MAC CE，所述第一MAC CE用于传输BFRQ信息；
或者，检测到发生波束失败，且识别到新的波束的情况下，触发第一MAC CE，所述第一MAC CE用于传输BFRQ信息。
在本公开实施例中，不同第一MAC CE(用于传输BFRQ信息的MAC CE，即MAC CE for BFRQ)对应的SR可以不同，例如，不同的辅小区SCell的MAC CE for BFRQ对应不同的SR。
可选的，上述第一MAC CE生成后，该第一MAC CE处于待发送pending状态。在该pending状态下，终端可以发送该第一MAC CE。
应理解，本实施例中，在触发生成第一MAC CE后，即可理解为存在待发送的BFRQ信息。
进一步的，上述第二触发条件具体内容可以根据实际需要进行设置，在一可选实施例中，该第二触发条件包括以下任一项：
向所述网络设备发送BFRQ信息；
完成波束失败恢复；
接收到所述网络设备发送的无线资源控制(Radio Resource Control，RRC)、 媒体接入控制控制元素MAC CE和下行控制信息(Downlink Control Information，DCI)中的至少一项；
释放或去激活发生波束失败的小区；
释放或去激活发生波束失败的带宽部分BWP；
释放或去激活发生波束失败的发送接收点TRP；
切换到新的小区；
切换到新的带宽部分BWP；
切换到新的发送接收点TRP；
切换到新的波束。
在本公开实施例中，接收到所述网络设备发送的RRC、MAC CE和DCI中的至少一项，可以理解为网络设备通过RRC信令、MAC CE命令和DCI信令中的至少一项，向所述终端发送调度信令、波束训练的相关信令、释放或去激活信令、切换信令等。具体的，RRC信令、MAC CE命令和DCI信令可以是在发生波束失败的目标对象上传输的，也可以是在未发生波束失败的目标对象上传输的。
为了更好的理解本公开，以下以BFRQ信息关联的目标对象为小区，且BFRQ信息由MAC CE承载为例，对本公开的具体实现过程进行详细说明。具体的，可以包括以下步骤：
步骤1，终端测量BFD RS，根据测量结果判断在至少一个目标对象是否发生波束失败事件。
步骤2，终端测量用于新的候选波束识别的下行参考信号(DL RS for new beam identification)，确定是否找到新的波束(new beam)。该步骤2与步骤1不存在先后关系。
步骤3，终端触发生成用于传输BFRQ信息的MAC CE(即MAC CE for BFRQ)。
用于传输BFRQ信息的MAC CE可以是专用于传输BFRQ的MAC CE(该MAC CE不同于相关技术中的MAC CE)，例如使用新的逻辑信道头标识。用于传输BFRQ信息的MAC CE还可以是用于传输其他上行信息的MAC CE，通过该MAC CE中的预留bit新定义值来标识该MAC CE是否用于传输 BFRQ信息。
进一步的，在检测到目标对象发生波束失败的情况下，也触发生成MAC CE for BFRQ，该MAC CE for BFRQ也处于pending状态；或者，在检测到目标对象发生波束失败，且识别到所述目标对象存在新的波束时，也触发生成MAC CE for BFRQ，该MAC CE for BFRQ也处于pending状态。
步骤4，如满足第一触发条件，则终端向网络设备发送SR.
其中，该SR可以为相关技术中的SR；或者，该SR为专用于波束失败恢复的SR，如dedicated SR，该dedicated SR用于通知网络将有BFRQ信息发送给网络，也即该dedicated SR用于触发用来发送MAC CE for BFRQ的上行资源(PUSCH)。
可选的，该SR处于pending状态。
可选的，该SR由终端周期性持续向网络发送。
步骤5，终端向网络设备发送MAC CE for BFRQ
