Description

一种发送SR的方法及设备
相关申请的交叉引用
本申请要求在2020年01月06日提交中国专利局、申请号为202010010996.X、申请名称为“一种发送SR的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种发送SR(Scheduling Request，调度请求)的方法及设备。
背景技术
当终端需要进行数据传输时，终端向网络侧设备发送调度请求(Scheduling Request，SR)以请求上行资源。在SR初始触发时，会设置SR计数(SR_COUNTER)为0，SR每成功发送一次，SR_COUNTER累加1，当SR_COUNTER累加到最大值SR_transmitMax时，UE将触发随机接入过程，即通过随机接入过程来获取上行(Uplink，UL)授权，以便在UL资源上进行数据传输。
在新一代无证无线电(New Radio in Unlicensed Spectrum，NR-U)网络中使用的是非授权频谱发送SR。在非授权频谱上，为了减少使用非授权频谱内用户造成的干扰，需要进行信道检测，在信道空闲时发送SR，若信道被占用则停止发送SR。如果一直无法等到非授权频谱的信道空闲，终端没有发送SR，因此没有办法对SR_COUNTER累加，导致无法累加到SR_transmitMax，无法通过随机接入过程来获取UL授权，最终导致终端无法获取UL资源，数据传输时延增加。
发明内容
本申请实施例提供一种发送SR的方法及设备，用以通过随机接入过程获取UL授权，以使终端通过获取的UL资源进行数据传输，降低数据传输时延。
第一方面，本申请实施例提供一种发送SR的方法，该方法包括：

在一种可能的实现方式中，终端通过如下方式判断是否满足发送调度请求SR的更新条件：
若终端确定连续一个或连续多个SR发送资源无法发送SR，则确定满足发送SR的更新条件；和/或
若终端确定在设定时长内SR发送资源无法发送SR，则确定满足发送SR的更新条件。
在一种可能的实现方式中，一个或连续多个无法发送SR的SR发送资源的数量是网络侧设备配置的或预先定义的；和/或
设定时长是网络侧设备配置的或预先定义的。
上述方法，给出终端确定是否满足发送SR的更新条件的判定条件，当满足判定条件后，终端即确定满足发送SR的更新条件，进一步对SR配置信息进行更新，给出判定条件，以便终端更加准确的确定在什么时候对SR配置信息进行更新，并使用更新后的SR配置信息发送SR，以便获取上行资源，使用获取的上行资源进行数据传输，减少数据传输延时。
在一种可能的实现方式中，终端通过如下方式确定SR发送资源是否无法发送SR：

上述方法，由于终端在确定是否满足发送调度请求SR的更新条件时，需要确定SR发送资源是否无法发送SR，只有在SR发送资源无法发送SR且满足上述判定条件时，才会更新SR配置信息，因此终端需要确定SR发送资源是否无法发送SR，具体的，当终端确定SR发送资源与其他资源发生冲突和/或确定SR发送信道忙时，确定SR发送资源无法发送SR，给出判定当前的SR发送资源是否无法发送SR的判定条件，以便进一步确定是否满足发送SR的更新条件。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)本申请实施例中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。
(2)本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
(3)“和/或”，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。字符“/”一般表示前后关联对象是一种“或”的关系。
终端在进行数据传输时，终端需要向网络侧设备发送自身有上行数据需要传输，以便网络侧设备决定是否给终端分配上行资源。因此NR(New radio，下一代无线)一个上行调度请求(Scheduling Request，SR)的机制。
终端通过SR向网络侧设备发送需要上行传输资源，以便用于上行共享信道(Uplink-Shared Channel，UL-SCH)传输；网络侧设备在已分配的SR资源上检测是否有终端发送SR，网络侧设备在接收到SR后，为终端分配上行资源，分配的上行资源至少足够终端发送缓存状态报告(Buffer Status Report，BSR)的资源。
目前，SR传输有两种形式，分别为专用SR传输和随机接入SR传输；
专用SR传输是使用网络侧设备配置的物理上行控制信道(Physical Uplink Control Channle，PUCCH)专用资源传输SR。
随机接入SR传输是通过随机接入过程获取上行资源。
目前，考虑到不同业务具有不同的时延要求，5G系统中允许网络侧设备为终端配置多套专用SR资源，根据不同业务选择其中的SR资源，还可以配置每个逻辑信道和专用SR资源的映射关系。终端确定有常规BSR触发时，首先确定触发常规BSR的逻辑信道；若确定没有针对该常规BSR的UL资源，则终端根据该逻辑信道和专用SR资源的映射关系选择可用的专用SR资源，并利用该专用SR资源发送SR。如果触发常规BSR的逻辑信道没有配置专用SR资源，将会触发终端发起随机接入SR。此外，当终端使用专用SR资源达到最大传输次数后，也会触发随机接入SR。
若专用SR资源无法发送SR后，终端还需要进行通知无线资源控制(Radio Resource Control，RRC)层释放所有服务小区对应的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源、通知RRC层释放所有服务小区对应的探测无线信号(Sounding Radio Signal，SRS)资源，清空上/下行半持续调度的资源等过程。
媒体接入控制(Medium Access control，MAC)实体可以被配置0个，1个或多个SR配置。一个SR配置包括多个带宽分片(Bandwidth Part，BWP)和小区上的PUCCH资源。对于一个逻辑信道，每个BWP上最多只能配置一个PUCCH资源。
每一个SR配置对应1个或多个逻辑信道，每个逻辑信道可以对应0个或1个SR，其中SR配置对应的逻辑信道及逻辑信道对应的SR由RRC信令配置。
其中，能够触发BSR的SR为pending(等待)SR。
因为UE没有物理上行共享信道(Physical Uplink Share Channel，PUSCH)资源发送BSR，所以UE在PUCCH上发送SR请求UL资源。网络侧设备可 以为每个UE分配一个专用SR资源用于发送SR。专用SR资源是周期性的，每n个时隙或符号出现一次。
如图1所示，为SR传输的一个例子：其中UE在数据到达后，触发了一个SR，并在下一个最近的SR资源上发送了SR，接着UE收到了UL授权，并在UL授权指示的PUSCH(UL-SCH)上发送了数据，发送的数据一般是指包含BSR的数据包。
在SR初始触发时，会设置参数SR_COUNTER为0，SR每成功发送一次，SR_COUNTER累加1，如果SR_COUNTER累加到最大值SR_transmitMax，UE将触发随机接入过程，即通过随机接入过程来获取UL授权。
在NR-U网络中使用的是非授权频谱发送SR。在非授权频谱上，为了减少使用非授权频谱内用户造成的干扰，需要进行信道检测，在信道空闲时发送SR，若信道被占用则停止发送SR。如果一直无法等到非授权频谱的信道空闲，终端没有发送SR，因此没有办法对SR_COUNTER累加，导致无法累加到SR_transmitMax，无法通过随机接入过程来获取UL授权，最终导致终端无法获取UL资源，数据传输时延增加。
基于上述内容，本申请提供一种发送SR的方法及设备，来解决使用费授权频谱发送SR，如果一种无法等到非授权频谱的信道空闲，同时由于终端实际没有发送SR，从而也无法累积SR_COUNTER，从而无法达到SR_COUNTER的最大值。所以终端无法通过随机接入过程获取UL授权，从而造成终端无法获取UL资源，导致数据传输延时增加的问题。本申请中：终端判断是否满足发送SR的更新条件，在确定满足发送SR的更新条件后，对SR配置信息进行更新，并使用更新后的SR配置信息发送SR，以提高发送SR的成功率，进一步通过随机接入过程获取UL授权，并通过获取的UL资源进行数据传输，降低数据传输延时。
本申请实施例中，终端是一种具有无线通信功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端可以是手机(Mobile  Phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(Industrial Control)中的无线终端、无人驾驶(Self Driving)中的无线终端、远程医疗(Remote Medical)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety)中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端等；还可以是各种形式的终端，移动台(Mobile Station，MS)，终端(Terminal Device)。
网络侧设备可以是基站，是一种为终端提供无线通信功能的设备，包括但不限于：5G中的gNB、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home Evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、传输点(Transmitting and Receiving Point，TRP)、发射点(Transmitting Point，TP)、移动交换中心等。本申请中的基站还可以是未来可能出现的其他通信系统中为终端提供无线通信功能的设备。
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
如图2所示，为本申请实施例提供的一种发送SR的方法流程图，包括如下步骤：
步骤200，终端判断是否满足发送调度请求SR的更新条件。
在本申请中，终端确定逻辑信道上有数据到达，并触发BSR后，但确定没有对应逻辑信道的UL授权，无法通过上行资源传输BSR时，终端触发SR以获取用于数据传输的上行资源。
终端触发SR后，在非授权频谱资源上发送SR。由于在非授权频谱资源 上发送SR时，非授权频谱资源可能与其他资源发生冲突，或终端探测到SR发送信道处于非空闲态即SR发送信道忙，此时终端在非授权频谱资源上无法发送SR，若长时间无法发送SR，则就无法获取UL授权，导致无法通过UL资源传输BSR，传输延时增加。
为了尽快发送SR，可以对SR配置信息进行更新，如将非授权频谱资源切换成授权频谱资源，在授权频谱资源上发送SR，或提升SR发送优先级，以在发生冲突时，优先发送SR。但是对SR配置信息进行更新之前，终端必须要判断是否满足发送SR的更新条件，只用在满足发送SR的更新条件时，终端才可对SR配置信息进行更新。
步骤210，若确定满足发送SR的更新条件，终端对SR配置信息进行更新，并使用更新后的SR配置信息发送SR。
在本申请中，当确定满足发送SR的更新条件后，终端对SR配置信息进行更新，并使用更新后的SR配置信息发送SR；以提高发送SR的成功率，以获取网络侧设备根据SR分配的上行资源，并在上行资源上进行数据传输，降低数据传输延时。
在本申请中，终端通过如下方式确定是否满足SR的更新条件：
方式一：终端确定一个或连续多个SR发送资源无法发送SR后，确定满足SR的更新条件。
在此情况下，设置一个计数器，用于对连续多个SR发送资源无法发送SR进行计数，一个或连续多个无法发送SR的SR发送资源的数量为网络侧设备配置或预先定义的；当确定一个或连续多个SR发送资源无法发送SR，确定满足SR的更新条件。
比如，预设无法发送SR的SR发送资源的数量为3，当连续3个SR发送资源无法发送SR后，确定满足SR的更新条件。若第一个SR发送资源无法发送SR，但是第二个SR发送资源成功发送SR，此时计数器重新计数。
方式二：终端确定在设定时长内SR发送资源无法发送SR后，确定满足发送SR的更新条件。
在此情况下，设置一个计时器，用于对发送SR进行计时，当确定在设定时长内，仍无法发送SR后，确定满足发送SR的更新条件。其中计时器的设定时长是网络侧设备配置的或预先定义的。
在本申请中，对SR配置信息进行更新时：对SR配置信息中的SR发送资源进行更新；和/或
对SR配置信息中的SR发送优先级进行更新。
其中，对SR配置信息中的SR发送资源进行更新，为将非授权频谱资源切换成授权频谱资源，且授权频谱资源是网络侧设备配置的。
对SR配置信息中的SR发送优先级进行更新，为提升SR发送优先级，其中优先级包括：SR配置的优先级和/或与所述SR相对应的逻辑信道的优先级，且优先级时网络侧设备配置的。
在本申请中，只有在满足更新条件时，才会对SR配置信息进行更新，并使用更新后的SR配置信息发送SR，但本申请中存在多种判定是否满足SR的更新条件的判定条件，且在满足SR的更新条件后，存在两种对SR配置信息进行更新方式。
具体通过下列实施例进行详细介绍。
实施例一：对SR配置信息中的SR发送资源进行更新。
由于本申请中是终端在确定满足发送SR的更新条件后，对SR配置信息进行更新。
终端通过如下方式判断是否满足发送SR的更新条件：
若确定一个或连续多个个SR发送资源无法发送SR，则确定满足发送SR的更新条件；和/或
若确定在设定时长内SR发送资源无法发送SR，则确定满足发送SR的更新条件。
因此存在如下两种情况：
情况一：当确定一个或连续多个SR发送资源无法发送SR后，对SR配置信息中的SR发送资源进行更新。
在本实施例中，当终端确定逻辑信道上有数据到达，并触发BSR后，确定没有对应触发BSR的UL授权，无法进行BSR传输时，终端通过非授权频谱资源发送SR，并启动计数器；
其中，通过非授权频谱资源发送SR是网络侧设备预先配置的参数信息；计数器的门限值为无法发送SR的SR发送资源的数量，无法发送SR的SR发送资源的数量可以是网络侧设备配置的参数信息，还可以是预先定义的。
进一步，终端判断当前SR的发送资源是否可以发送SR，在确定当前SR的发送资源无法发送SR后，计数器的计数值累计加1，或在门限值的基础上减1；
其中，终端通过如下方式确定当前SR发送资源是否无法发送SR：
若确定SR发送资源与其他资源发生冲突，则确定SR发送资源无法发送SR；和/或
若通过LBT确定SR发送信道忙，则确定SR发送资源无法发送SR。
因此，当出现上述情况时，若计数器采用累加的方式计数，则在当前计数器的数值基础上加1，并在确定累加值达到门限值后，确定满足发送SR的更新条件，对SR配置信息中的发送资源进行更新；
若计数器采用递减的方式，则在当前计数器的数值基础上减1。在确定由门限值减到0后，终端确定满足发送SR的更新条件，并对SR配置信息中的发送资源进行更新。
其中，对SR配置信息中的SR发送资源进行更新为：将非授权频谱资源切换成授权频谱资源；
在切换成授权频谱资源后，在授权频谱资源上发送SR。
相应的，网络侧设备在对应的非授权频谱资源和授权频谱资源上接收终端发送的SR；
网络侧设备在接收终端发送的SR时，首先在非授权频谱资源上接收终端发送的SR，若在非授权频谱资源的位置上没有接收到SR，则在授权频谱资源的位置上接收SR。
并在接收到终端发送的SR后，向终端发送UL授权，以使终端在UL资源上发送BSR。
如图3所示，为本申请实施例提供的第一种发送SR的示意图。从图3中可知，当终端在非授权频谱资源上发送SR上连续3次无法发送SR后，在授权频谱资源上发送SR。
情况二：当确定在设定时长内SR发送资源无法发送SR后，对SR配置信息中的SR发送资源进行更新。
在本实施例中，当终端确定逻辑信道上有数据到达，并触发BSR后，确定没有对应触发BSR的UL授权，无法进行BSR传输时，终端通过非授权频谱资源发送SR，并启动计时器；
其中，通过非授权频谱资源发送SR是网络侧设备预先配置的参数信息；计时器的设定时长可以是网络侧设备预先配置的参数信息，还可以是预先定义的。
进一步，终端判断当前SR的发送资源是否可以发送SR，在确定当前SR的发送资源无法发送SR后，在确定计时器达到设定时长后仍无法发送SR后，对SR配置信息中的发送资源进行更新。
其中，终端通过如下方式确定当前SR发送资源是否无法发送SR：
若确定SR发送资源与其他资源发生冲突，则确定SR发送资源无法发送SR；和/或
若通过LBT确定SR发送信道忙，则确定SR发送资源无法发送SR。
在本申请中，当终端触发在非授权频谱资源上发送SR时，启动计时器开始计时，此时计时器的初始时刻可以为0，也可以为设定时长；当计时器的初始时刻为0时，采用正计时的方式，当计时器的到达设定时长后，仍无法发送SR时，确定满足SR的更新条件，对SR配置信息中的发送资源进行更新；或当计时器的初始时刻为设定时长时，采用倒计时的方式，当计时器到0后，仍无法发送SR时，确定满足SR的更新条件，对SR配置信息中的发送资源进行更新。
其中，对SR配置信息中的发送资源进行更新为：将非授权频谱资源切换成授权频谱资源；
在切换成授权频谱资源后，在授权频谱资源上发送SR。
相应的，网络侧设备在对应的非授权频谱资源和授权频谱资源上接收终端发送的SR；
网络侧设备在接收终端发送的SR时，首先在非授权频谱资源上接收终端发送的SR，若在非授权频谱资源的位置上没有接收到SR，则在授权频谱资源的位置上接收SR。
并在接收到终端发送的SR后，向终端发送UL授权，以使终端在UL资源上发送BSR。
如图4所示，为本申请实施例提供的第二种发送SR的示意图，从图4中可知终端在非授权频谱资源上发送SR时长到达设定时长后，仍无法发送SR，则在授权频谱资源上发送SR。
实施例二：对SR配置信息中的SR发送优先级进行更新。
由于本申请中是终端在确定满足发送SR的更新条件后，对SR配置信息进行更新。
终端通过如下方式判断是否满足发送SR的更新条件：
若确定一个或连续多个SR发送资源无法发送SR，则确定满足发送SR的更新条件；和/或
若确定在设定时长内SR发送资源无法发送SR，则确定满足发送SR的更新条件。
因此存在如下两种情况：
情况三，当确定一个或连续多个SR发送资源无法发送SR后，对SR配置信息中的SR发送优先级进行更新。
在本实施例中，当终端确定逻辑信道上有数据到达，并触发BSR后，确定没有对应触发BSR的UL授权，无法进行BSR传输时，终端通过非授权频谱资源发送SR，并启动计数器；
其中，通过非授权频谱资源发送SR是网络侧设备预先配置的参数信息；计数器的门限值为无法发送SR的SR发送资源的数量，无法发送SR的SR发送资源的数量可以是网络侧设备预先配置的参数信息，还可以是预先定义的。
进一步，终端判断当前SR的发送资源是否可以发送SR，在确定当前SR的发送资源无法发送SR后，计数器的计数值累计加1，或在门限值的基础上减1；
其中，终端通过如下方式确定当前SR发送资源是否无法发送SR：
若确定SR发送资源与其他资源发生冲突，则确定SR发送资源无法发送SR；和/或
若通过LBT确定SR发送信道忙，则确定SR发送资源无法发送SR。
因此，当出现上述情况时，若计数器采用累加的方式计数，则在当前计数器的数值基础上加1，并在确定累加值达到门限值后，确定满足发送SR的更新条件，对SR配置信息中的SR发送优先级进行更新；
若计数器采用递减的方式，则在当前计数器的数值基础上减1。在确定由门限值减到0后，终端确定满足发送SR的更新条件，并对SR配置信息中的发送资源进行更新。
对SR配置信息中的SR发送优先级进行更新为：提升SR的发送优先级，其中优先级包括：SR配置的优先级和/或与SR相对应的逻辑信道的优先级。
其中，SR配置的优先级和/或与SR相对应的逻辑信道的优先级是由网络侧设备配置的参数信息；初始时，网络侧设备配置第一优先级信息、第二优先级信息等多个优先级信息；其中第二优先级信息第一优先级信息，第一优先级信息和第二优先级可以为SR配置的优先级和/或与SR相对应的逻辑信道的优先级，第二优先级信息也可以为一个门限值。
在提升SR发送优先级后，在非授权频谱资源上使用更新后的优先级信息发送SR；比如由第一优先级更新到第二优先级，则使用第二优先级在非授权频谱上发送SR。
当优先级更新后，在资源发生碰撞时，终端将优先发送SR。其中，资源碰撞可以是和PUSCH资源发生碰撞，比如配置授权频谱资源，或动态调度资源。
相应的，网络侧设备在对应的非授权频谱资源上接收终端发送的SR；
并在接收到终端发送的SR后，向终端发送UL授权，以使终端在UL资源上发送BSR。
如图5所示，为本申请实施例提供的第三种发送SR的示意图，从图4中可知，当终端在非授权频谱资源上发送SR上连续3次无法发送SR后，提升SR配置的优先级，并在非授权频谱资源上的下一个SR资源上使用提升后的优先级发送SR。
情况四，当确定在设定时长内SR发送资源无法发送SR后，对SR配置信息中的SR发送优先级进行更新。
在本实施例中，当终端确定逻辑信道上有数据到达，并触发BSR后，确定没有对应触发BSR的UL授权，无法进行BSR传输时，终端通过非授权频谱资源发送SR，并启动计时器；
其中，通过非授权频谱资源发送SR是网络侧设备预先配置的参数信息；计时器的设定时长可以是网络侧设备预先配置的参数信息，还可以是预先定义的。
进一步，终端判断当前SR的发送资源是否可以发送SR，在确定当前SR的发送资源无法发送SR后，在确定计时器达到设定时长后仍无法发送SR后，对SR配置信息中的发送资源进行更新。
其中，终端通过如下方式确定当前SR发送资源是否无法发送SR：
若确定SR发送资源与其他资源发生冲突，则确定SR发送资源无法发送SR；和/或
若通过LBT确定SR发送信道忙，则确定SR发送资源无法发送SR。
在本申请中，当终端触发在非授权频谱资源上发送SR时，启动计时器开始计时，此时计时器的初始时刻可以为0，也可以为设定时长；当计时器的初 始时刻为0时，采用正计时的方式，当计时器的到达设定时长后，仍无法发送SR时，确定满足SR的更新条件，对SR配置信息中的发送资源进行更新；或当计时器的初始时刻为设定时长时，采用倒计时的方式，当计时器到0后，仍无法发送SR时，确定满足SR的更新条件，对SR配置信息中的发送资源进行更新。
对SR配置信息中的SR发送优先级进行更新为：提升SR的发送优先级，其中优先级包括：SR配置的优先级和/或与SR相对应的逻辑信道的优先级。
其中，SR配置的优先级和/或与SR相对应的逻辑信道的优先级是由网络侧设备配置的参数信息；初始时，网络侧设备配置第一优先级信息、第二优先级信息等多个优先级信息；其中第二优先级信息第一优先级信息，第一优先级信息和第二优先级可以为SR配置的优先级和/或与SR相对应的逻辑信道的优先级，第二优先级信息也可以为一个门限值。
在提升SR的发送优先级后，在非授权频谱资源上使用更新后的优先级信息发送SR；比如由第一优先级更新到第二优先级，则使用第二优先级在非授权频谱上发送SR。
当优先级更新后，在资源发生碰撞时，终端将优先发送SR。其中，资源碰撞，可以是和PUSCH资源发生碰撞，比如配置授权频谱资源，或动态调度资源。
相应的，网络侧设备在对应的非授权频谱资源上接收终端发送的SR；
并在接收到终端发送的SR后，向终端发送UL授权，以使终端在UL资源上发送BSR。
如图6所示，为本申请实施例提供的第四种发送SR的示意图，从图6中可知，当终端在非授权频谱资源上设定时长内仍无法发送SR，则提升SR配置的优先级，并在非授权频谱资源上的下一个SR资源上使用提升后的优先级发送SR。
需要说明的是，上述情况可以进行任一组合，比如在设定时长内一个或连续多个SR发送资源无法发送SR后，对SR发送优先级进行更新以及对SR 配置信息中的SR发送资源进行更新，以通过更新后的SR发送资源发送SR，此时SR的发送优先级已更新，其他方式类似，在此不再赘述。
如图7所示，为本申请实施例提供的一种发送SR的方法流程图，包括如下步骤：
步骤700，网络侧设备确定配置参数；
其中，配置参数包括逻辑信道对应的SR配置信息，SR配置信息包括下列的部分或全部：非授权频谱资源、授权频谱资源、第一优先级信息、第二优先级信息、触发在SR配置资源发送的逻辑信道信息；
第一优先级信息为SR的优先级信息或与SR相对应的逻辑信道的优先级信息，第二优先级信息高于第一优先级信息。
在本申请，第二优先级信息可以是一个门限值。
步骤710，网络侧设备将配置参数发送给终端，以使终端确定满足发送SR的更新条件后，根据配置参数对SR配置信息进行更新，并使用更新后的SR配置信息发送SR。
在一种可能的实现方式中，网络侧设备还为终端配置计数器的门限值，即无法发送SR的SR发送资源的数量；以及为终端配置计时器的设定时长。
基于同一发明构思，本申请实施例中还提供了一种发送SR的设备，由于该设备对应的方法是本申请实施例发送SR的方法，并且该设备解决问题的原理与该方法相似，因此该设备的实施可以参见方法的实施，重复之处不再赘述。
