附图说明
为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
首先，对本公开涉及的一些名词进行简单介绍：
PDCCH监听自适应：
在R17节能(power saving)项目中提出了PDCCH监听自适应(monitoring adaptation)方案，即：采用调度DCI中的一个包含N个比特(bit)的比特域(bitfield)，指示PDCCH监听自适应行为。
当终端设备收到PDCCH监听自适应指示(也就是上述DCI)以后，终端设备行为可以采用如下之一：
·行为1:不激活跳过PDCCH(PDCCHskipping)
·行为1A:在X时长内停止PDCCH监听(也即PDCCH skipping)。网络设备可以在DCI中动态的指示X的数值。
·行为2:停止监听SSSG#1和SSSG#2(如果有该配置)中的搜索空间，监听SSSG#0中的搜索空间。
·行为2A:停止监听SSSG#0和SSSG#2(如果有该配置)中的搜索空间，监听SSSG#1中的搜索空间。
·行为2B:停止监听SSSG#0和SSSG#1中的搜索空间，监听SSSG#2(如果有该配置)中的搜索空间。
取消挂起的SR：
相关技术中，定义了如下两种取消挂起的SR的原因：
(1)终端设备发送了包含缓存状态报告(Buffer State Report，BSR)的媒体接入控制(Medium Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)，则可以取消在组装该MAC PDU之前的挂起的SR。
(2)终端设备收到了上行调度指令，且能够满足所有挂起的上行数据的传输需求，则可以取消挂起的SR。
如果终端设备在发送SR之后，SR尚处于挂起状态，那么终端设备在接收到网络设备发送的PDCCH监听自适应指示之后，应该如何处理SR过程，相关技术中尚未提供解决方案。
下面，对本公开实施例提供的解决方案进行说明。
图1示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个接入网设备120。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端设备(简称为“终端”)14提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G新空口(New Radio，NR)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本公开实施例中的描 述，上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端设备。接入网设备120与终端设备14之间通过某种空口技术互相通信，例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本公开实施例也可以应用于这些通信系统。
图2示出了本公开一个示例性实施例提供的调度请求过程的处理方法的方法流程图，该方法应用于图1所示的通信系统中的终端设备中，该方法包括：
步骤210：终端设备接收网络设备发送的PDCCH监听自适应指示。
网络设备可以向终端设备发送PDCCH监听自适应指示。相应的，终端设备 接收由网络设备发送的PDCCH监听自适应指示。
其中，PDCCH监听自适应指示是网络设备向终端设备发送的，用于指示进行PDCCH监听调整的信息。
步骤220：终端设备在存在SR挂起，且接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，取消挂起的SR。
在本公开实施例中，终端设备在执行调度请求过程，该调度请求过程是通过发送SR来请求获取上行资源的过程，且当前的进度为：终端设备已经向网络设备发送了SR，该SR处于挂起(pending)状态，终端设备侧存在待传输的挂起数据。
其中，挂起状态是SR在被触发之后，尚未被取消时的一种状态。
在存在SR挂起的情况下，终端设备接收到网络设备发送的PDCCH监听自适应指示；其中，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，终端设备取消挂起的SR。也即，在存在SR挂起且接收到包含第一指示信息的PDCCH监听自适应指示携带的情况下，终端设备取消挂起的SR。
可以理解的是，在终端设备执行调度请求过程，通过发送SR来请求获取上行资源时，在终端设备发送完SR，且SR处于挂起状态之后，终端设备需要通过进行PDCCH监听，从而确认网络设备是否对SR进行响应。由于终端设备后续接收到了PDCCH监听自适应指示，且PDCCH监听自适应指示用于指示进行PDCCH监听调整，因此，接收到的PDCCH监听自适应指示会对终端设备确认网络设备是否对SR进行响应的行为产生影响。
其中，第一指示信息是PDCCH监听自适应指示中携带的信息。
在本公开实施例中，第一指示信息是使得终端设备认为SR难以得到满足的信息。因此，终端设备取消挂起的SR，结束当前的调度请求过程。上述SR难以得到满足也可以理解为：SR没有继续挂起的必要、调度请求过程失败等等。
综上所述，本实施例提供的调度请求过程的处理方法，在存在SR挂起的情况下，终端设备接收到网络设备发送的PDCCH监听自适应指示，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，由于第一指示信息使得终端设备认为SR难以得到满足，因此终端设备取消挂起的SR，避免终端设备不必要的持续挂起SR，浪费终端设备的存储计算资源。
在一种可能的实施方式中，第一指示信息包括：指示跳过PDCCH的信息。
图3示出了本公开一个示例性实施例提供的调度请求过程的处理方法的方法流程图，该方法应用于图1所示的通信系统中的终端设备中，该方法包括：
步骤310：终端设备接收网络设备发送的PDCCH监听自适应指示。
在一些实施方式中，网络设备向终端设备发送PDCCH监听自适应指示，相应的，终端设备接收网络设备发送的PDCCH监听自适应指示。
其中，PDCCH监听自适应指示是网络设备向终端设备发送的，用于指示进行PDCCH监听调整的信息。
可选的，PDCCH监听自适应指示承载在调度DCI中。示例性的，调度DCI中包括一个包含N个比特的比特域，该比特域用于指示PDCCH监听自适应指示。
·调度DCI为用于下行调度的DCI。
也即，PDCCH监听自适应指示承载在用于下行调度的DCI中。
·调度DCI为用于上行调度的DCI。
也即，PDCCH监听自适应指示承载在用于上行调度的DCI中。
示例性的，此处的上行调度不能满足与SR对应的所有待传输的挂起数据的传输要求。
其中，传输要求可以包括与如下方面相关的要求：
(1)上行调度分配的资源的数量不足够所有待传输的挂起数据的传输。
(2)上行调度分配的资源的特征不能满足所有待传输的挂起数据的服务质量(Quality of Service，QoS)要求。
例如，某些逻辑信道上待传输的挂起数据要求所映射的物理层资源物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的时域长度最大为4个时域符号。如果上行调度分配的PUSCH的时域长度是8个符号，那么该上行调度分配的资源不能满足该逻辑信道的挂起数据的传输。
步骤320：终端设备在存在SR挂起，且接收到的PDCCH监听自适应指示携带有第一指示信息，第一指示信息包括：指示跳过PDCCH的信息的情况下，取消挂起的SR。
其中，指示跳过PDCCH的信息(即PDCCH skipping指示)指的是指示终端设备在一段时间内不执行PDCCH监听的信息。
可以理解的是，在终端设备执行调度请求过程，通过发送SR来请求获取上行资源时，终端设备在发送完SR，SR处于挂起状态之后，终端设备需要通过进行PDCCH监听，从而确认网络设备是否对SR进行响应。由于终端设备后续接收到了PDCCH监听自适应指示，且PDCCH监听自适应指示携带有第一指示信息，第一指示信息包括：指示跳过PDCCH的信息，终端设备将基于第一指示信息，在一段时间内不执行PDCCH监听，此时若继续将SR处于挂起状态，终端设备也无法确认网络设备是否对SR进行响应，因此，终端设备取消挂起的SR。
可选的，指示跳过PDCCH的信息携带跳过持续时间，且跳过持续时间超过第一时长；其中，跳过持续时间是不监听PDCCH的持续时间。可选的，PDCCH包含Type 3公共搜索空间(common search space)和UE特定搜索空间(UE specific search space)。
也即，指示跳过PDCCH的信息指示的跳过持续时间(即skipping duration)大于等于(或大于)第一时长。
示例性的，第一时长是终端设备基于网络设备侧的配置，计算得到的一个时间阈值。上述配置可以是与SR相关的配置。
如果跳过持续时间小于第一时长，即终端设备跳过监听PDCCH的时间较短，在跳过持续时间之后，终端设备还可以继续监听用于上行调度的DCI。在该较短的跳过持续时间内，无需取消SR。
如果跳过持续时间大于第一时长，即终端设备跳过监听PDCCH的时间较长，在该跳过持续时间内，终端设备将无法获得用于上行调度的DCI，即调度请求在该较长时段内都无法被满足，所以可以取消SR。
下面，对第一时长进行进一步说明。
·第一时长是根据网络设备配置的调度请求-禁止定时器(sr-ProhibitTimer)确定的时长。
示例性的，第一时长＝sr-ProhibitTimer。
其中，sr-ProhibitTimer是终端设备侧的一个计时器，其时长由网络设备进行配置。网络设备针对每个SR配置(SR configuration)可以配置一个sr-ProhibitTimer。对于每个SR configuration，终端设备在发送SR后，在sr-ProhibitTimer时长内禁止再次发送SR。
可选的，在网络设备配置了多个sr-ProhibitTimer的情况下，第一时长是根据多个sr-ProhibitTimer中的最大值确定的时长。
示例性的，第一时长＝sr-ProhibitTimer最大值。
·第一时长是根据网络设备配置的sr-ProhibitTimer和调度请求-传输最大值(sr-TransMax)确定的时长。
示例性的，第一时长＝sr-ProhibitTimer*sr-TransMax。
其中，sr-TransMax是终端设备可以重复发起SR的最大次数。网络设备针对每个SR configuration可以配置一个sr-TransMax。如果超出该重复传输次数而终端设备未收到网络设备答复，则认为发生了波束失败或链路失败。
可选的，在网络设备配置了多个sr-ProhibitTimer和多个sr-TransMax的情况下，第一时长是根据多个sr-ProhibitTimer中的最大值和多个sr-TransMax中的最大值确定的时长。
示例性的，第一时长＝sr-ProhibitTimer最大值*sr-TransMax最大值。
综上所述，本实施例提供的调度请求过程的处理方法，在存在SR挂起的情况下，终端设备接收到网络设备发送的PDCCH监听自适应指示，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，由于第一指示信息包括指示跳过PDCCH的信息，使得终端设备认为SR难以得到满足，因此终端设备取消挂起的SR，避免终端设备不必要的持续挂起SR，浪费终端设备的存储计算资源。
在另一种可能的实施方式中，第一指示信息包括：指示切换到空搜索空间集组(Search Space Set Group，SSSG)的信息。
图4示出了本公开一个示例性实施例提供的调度请求过程的处理方法的方法流程图，该方法应用于图1所示的通信系统中的终端设备中，该方法包括：
步骤410：终端设备接收网络设备发送的PDCCH监听自适应指示。
在一些实施方式中，网络设备可以向终端设备发送PDCCH监听自适应指示。相应的，终端设备接收由网络设备发送的PDCCH监听自适应指示。
其中，PDCCH监听自适应指示是网络设备向终端设备发送的，用于指示进行PDCCH监听调整的信息。
可选的，PDCCH监听自适应指示承载在调度DCI中。示例性的，调度DCI 中包括一个包含N个比特的比特域，该比特域用于指示PDCCH监听自适应指示。
·调度DCI为用于下行调度的DCI。
也即，PDCCH监听自适应指示承载在用于下行调度的DCI中。
·调度DCI为用于上行调度的DCI。
也即，PDCCH监听自适应指示承载在用于上行调度的DCI中。
示例性的，此处的上行调度不能满足与SR对应的所有待传输的挂起数据的传输要求。
其中，传输要求可以包括与如下方面相关的要求：
(1)上行调度分配的资源的数量不足够所有待传输的挂起数据的传输。
(2)上行调度分配的资源的特征不能满足所有待传输的挂起数据的QoS要求。
例如，某些逻辑信道上待传输的挂起数据要求所映射的物理层资源PUSCH的时域长度最大为4个时域符号。如果上行调度分配的PUSCH的时域长度是8个符号，那么该上行调度分配的资源不能满足该逻辑信道的挂起数据的传输。
步骤420：终端设备在存在SR挂起，且接收到的PDCCH监听自适应指示携带有第一指示信息，第一指示信息包括：指示切换到空SSSG的信息的情况下，取消挂起的SR。
其中，指示切换到空SSSG的信息指的是指示终端设备切换到一个SSSG，监听该SSSG中的搜索空间，且该SSSG中不包含任何搜索空间，是一个空SSSG(empty SSSG)。
可以理解的是，在终端设备执行调度请求过程，通过发送SR来请求获取上行资源时，终端设备在发送完SR，SR处于挂起状态之后，终端设备需要通过进行PDCCH监听，即，在搜索空间中检测网络设备是否有PDCCH发送给终端设备，从而确认网络设备是否对SR进行响应。由于终端设备后续接收到了PDCCH监听自适应指示，且PDCCH监听自适应指示携带有第一指示信息，第一指示信息包括：指示切换到空SSSG的信息，终端设备将基于第一指示信息，切换到不包含任何搜索空间的空SSSG，此时若继续将SR处于挂起状态，终端设备也无法确认网络设备是否对SR进行响应，因此，终端设备取消挂起的SR。
可选的，指示切换到空SSSG的信息携带定时值，且定时值超过第一时长； 其中，定时值是切换到空SSSG的持续时间。
也即，指示切换到空SSSG的信息的定时值大于等于(或大于)第一时长。
示例性的，第一时长是终端设备基于网络设备侧的配置，计算得到的一个时间阈值。上述配置可以是与SR相关的配置。
如果定时值小于第一时长，即终端设备切换到空SSSG、无法监听PDCCH的时间较短，在定时值之后，终端设备还可以继续监听用于上行调度的DCI。在该较短的定时值内，无需取消SR。
如果定时值大于第一时长，即终端设备切换到空SSSG、无法监听PDCCH的时间较长，在该定时值内终端设备将无法获得用于上行调度的DCI，即调度请求在该较长时段内都无法被满足，所以可以取消SR。
下面，对第一时长进行进一步说明。
·第一时长是根据网络设备配置的sr-ProhibitTimer确定的时长。
示例性的，第一时长＝sr-ProhibitTimer。
其中，sr-ProhibitTimer是终端设备侧的一个计时器，其时长由网络设备进行配置。网络设备针对每个SR配置(SR configuration)可以配置一个sr-ProhibitTimer。对于每个SR configuration，终端设备在发送SR后，在sr-ProhibitTimer时长内禁止再次发送SR。

其中，sr-TransMax是终端设备可以重复发起SR的最大次数。网络设备针对每个SR configuration可以配置一个sr-TransMax。如果超出该重复传输次数而终端设备未收到网络设备答复，则认为发生了波束失败或链路失败。
可选的，在网络设备配置了多个sr-ProhibitTimer和多个sr-TransMax的情况下，第一时长是根据多个sr-ProhibitTimer中的最大值和多个sr-TransMax中的最大值确定的时长。
示例性的，第一时长＝sr-ProhibitTimer最大值*sr-TransMax最大值。
综上所述，本实施例提供的调度请求过程的处理方法，在存在SR挂起的情 况下，终端设备接收到网络设备发送的PDCCH监听自适应指示，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，由于第一指示信息包括指示切换到空SSSG的信息，使得终端设备认为SR难以得到满足，因此终端设备取消挂起的SR，避免终端设备不必要的持续挂起SR，浪费终端设备的存储计算资源。

网络设备可以向终端设备发送PDCCH监听自适应指示。相应的，终端设备接收由网络设备发送的PDCCH监听自适应指示。
其中，PDCCH监听自适应指示是网络设备向终端设备发送的，用于指示进行PDCCH监听调整的信息。
在本公开实施例中，在终端设备接收到PDCCH监听自适应指示之前，终端设备在执行调度请求过程，该调度请求过程是通过发送SR来请求获取上行资源的过程，且当前的进度为：终端设备已经向网络设备发送了SR，该SR处于挂起(pending)状态，终端设备侧存在待传输的挂起数据。
其中，挂起状态是SR在被触发之后，尚未被取消时的一种状态。
在存在SR挂起的情况下，终端设备接收到网络设备发送的PDCCH监听自适应指示；其中，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，终端设备取消挂起的SR。也即，在存在SR挂起且接收到包含第一指示信息的PDCCH监听自适应指示携带的情况下，终端设备取消挂起的SR。
可以理解的是，在终端设备执行调度请求过程，通过发送SR来请求获取上行资源时，在终端设备发送完SR，且SR处于挂起状态之后，终端设备需要通过进行PDCCH监听，从而确认网络设备是否对SR进行响应。由于终端设备后续接收到了PDCCH监听自适应指示，且PDCCH监听自适应指示用于指示进行PDCCH监听调整，因此，接收到的PDCCH监听自适应指示会对终端设备确认网络设备是否对SR进行响应的行为产生影响。
其中，第一指示信息是PDCCH监听自适应指示中携带的信息。
在本公开实施例中，第一指示信息是使得终端设备认为SR难以得到满足的信息。因此，终端设备取消挂起的SR，结束当前的调度请求过程。上述SR难以得到满足也可以理解为：SR没有继续挂起的必要、调度请求过程失败等等。
综上所述，本实施例提供的调度请求过程的处理方法，在存在SR挂起的情况下，终端设备接收到网络设备发送的PDCCH监听自适应指示，在接收到的PDCCH监听自适应指示携带有第一指示信息的情况下，由于第一指示信息使得终端设备认为SR难以得到满足，因此终端设备取消挂起的SR，避免终端设备不必要的持续挂起SR，浪费终端设备的存储计算资源。
