Description

一种控制定时器的方法和装置
本申请中要求在2018年04月04日提交中国专利局、申请号为201810300184.1、申请名称为“一种控制定时器的方法和装置”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，特别涉及一种控制定时器的方法和装置。
背景技术
在移动通信领域，用户设备(UE)的不连续接收(discontinuous reception，DRX)是指UE在一段时间没有监听到物理下行控制信道(physical downlink control channel，PDCCH)的调度信息，则UE可以进入睡眠状态(sleep mode)，在睡眠状态下UE不去监听PDCCH信道，而在需要监听的时候，UE从睡眠状态中唤醒(wake up)，这样就可以达到降低UE功率消耗的目的。在进入睡眠状态之前，UE需要确定DRX重传定时器(DRX-retransmission timer)和DRX HARQ RTT(DRX混合自动重传请求-往返时间)定时器等定时器的计时均终止，以确定可以进入睡眠状态，而在这些定时器开始计时之前，UE需要根据当前激活的部分带宽(bandwidth part，BWP)的参数，配置这些定时器的定时时长。
然而，在BWP场景下，上述的定时机制存在不兼容的情况。
发明内容
本申请提供一种控制定时器的方法和装置，用以优化BWP场景下的定时器控制问题。
第一方面，本申请实施例提供配置定时器的方法，在用户设备响应第一消息激活第一部分带宽后，由用户设备执行以下中的一个步骤：控制目标定时器根据第二部分带宽的单位计时长度计时，直到目标定时器停止计时或目标定时器的计时超时后，控制目标定时器根据第一部分带宽的单位计时长度启动计时；或者，确定激活第一部分带宽时目标定时器的第一计数，根据第一计数，确定目标定时器的第二计数，控制目标定时器根据第一部分带宽的单位计时长度、从目标定时器的第二计数开始计时；或者，根据第一计数，确定第三计数，控制目标定时器根据第一部分带宽的单位计时长度和第三计数执行计时；或者，控制目标定时器根据第一部分带宽的单位计时长度，重新启动计时；或者停止目标定时器的计时或者令目标定时器超时；或者，控制目标定时器根据第一部分带宽的单位计时长度继续执行目标定时器的计时，以优化BWP场景下的定时器控制问题。
在一种可能的设计中，用户设备可以根据目标定时器的第一计数和调整倍率，确定目标定时器的第二计数，其中调整倍率根据第一部分带宽的单位计时长度和第二部分带宽的单位计时长度确定的，例如，调整倍率可以等于第一部分带宽的单位计时长度除以第二部分带宽的单位计时长度，则此时可以第二计数等于第一计数乘以调整倍率；或者调整倍率可以等于第二部分带宽的单位计时长度除以第一部分带宽的单位计时长度，则此时可以第二计数等于第一计数除以调整倍率。
在一种可能的设计中，第三计数为激活第一部分带宽时目标定时器的剩余计时数，该 剩余计时数用于指示目标定时器在超时前根据第二部分带宽的单位计时长度计时的剩余时隙数或剩余符号数，例如，目标定时器为DRX重传定时器，用户设备配置DRX重传定时器计时10个时隙，若第二部分带宽的时隙长度为1ms，用户设备在DRX重传定时器的计数为第8ms时激活第一部分带宽，则此时DRX重传定时器的第一计数为8ms，DRX重传定时器的剩余计时时长为2ms，可以根据以下方法确定第三计数：根据DRX重传定时器的剩余计时时长除以第二部分带宽的时隙长度，即确定第三计数为2。
在一种可能的设计中，用户设备可以确定第一部分带宽的单位计时长度大于第二部分带宽的单位计时长度；或者，确定第一部分带宽的单位计时长度小于第二部分带宽的单位计时长度。从而在第一部分带宽的单位计时长度与第二部分带宽的单位计时长度相同时，不再调整目标定时器。
在一种可能的设计中，用户设备还可以根据接收的第二消息，确定第一部分带宽的单位计时长度，和/或根据接收的第三消息，确定第二部分带宽的单位计时长度。这里的第二消息和第三消息可以相同。
在一种可能的设计中，单位计时长度为时隙长度，和/或单位计时长度为符号长度。其中，第一部分带宽的时隙长度和/或符号长度可以根据第一部分带宽的子载波间隔的配置确定，第二部分带宽的时隙长度和/或符号长度可以根据第二部分带宽的子载波间隔的配置确定。
在一种可能的设计中，用户设备还可以根据第一消息或者第四消息，激活第二部分带宽。

举例来说，如图3所示，UE 102可以根据网络侧设备101配置的时隙数量配置上行DRX重传定时器，例如，UE 102为上行DRX重传定时器配置时隙数量为10，假设当前UE 102激活的BWP1的时隙长度为1毫秒(ms)，则DRX重传定时器实际上需要计时的时长为10ms，若上行DRX重传定时器10ms的计时终止，则表示已监听BWP1的10个时隙；又如，UE 102为上行DRX-HARQ-RTT定时器配置的符号数量为10，假设当前UE 102激活的BWP1的时隙长度为1ms，若BWP1的时隙长度为符号长度的七倍，BWP1的符号长度为0.143ms，则上行DRX-HARQ-RTT定时器实际计数时长为1.43ms，若上行DRX-HARQ-RTT定时器1.43ms的计时终止，则说明已监听10个符号。
在UE 102需要将已经激活的BWP1切换为如图3所示的BWP2，或者UE 102需要在BWP1的基础上再次激活一个新的BWP2时，由于UE 102需要在新的BWP2上进行数据传输，UE 102应当控制DRX重传定时器在启动时就根据时隙数量和BWP2的时隙长度计时，和/或控制DRX HARQ RTT定时器在启动时就根据符号数量和BWP2的符号长度计时，但在UE 102激活新的BWP时，DRX重传定时器已经根据UE 102原本激活的BWP1的时隙长度开始计时并存在一个计数，和/或控制DRX HARQ RTT定时器已经根据UE 102原本激活的BWP的符号长度开始计时并存在一个计数，从而在激活BWP2之后，DRX重传定时器只能在之前计数的基础上按照BWP2的时隙长度计时，和/或，DRX HARQ RTT定时器只能在之前计数的基础上按照BWP2的符号长度计时；由于BWP的时隙长度和符号长度，可以根据BWP的子载波间隔(subcarrier spacing，SCS)确定，BWP2的SCS与UE102原本激活的BWP1的SCS可能不同，即BWP2的时隙长度与UE 102原本激活的BWP1的时隙长度不同，且BWP2的符号长度与UE 102BWP1的符号长度不同，以上计时方案 中DRX重传定时器已经存在的计数并不能准确反映已经监听的BWP2的时隙数量，和/或DRX HARQ RTT定时器已经存在的计数并不能准确反映已经监听的BWP2的符号数量，从而，UE 102不能准确判断是否可以进入睡眠状态。
下面以网络侧设备101与UE 102，第一部分带宽为图2所示的BWP2，第二部分带宽为图2所示的BWP1为例，说明本申请实施例提供的一种配置定时器的方法，如图4所示，该方法包括以下步骤：
步骤S101：UE 102响应网络侧设备101发送的第一消息，激活BWP2；这里的激活BWP2，可以是UE 102将激活的BWP从BWP1切换至BWP2，也可以是UE 102在激活BWP2同时保持BWP1为激活状态；
步骤S102-a：UE 102控制目标定时器根据BWP1的单位计时长度计时，直到目标定时器停止计时或目标定时器的计时超时，控制目标定时器根据BWP2的单位计时长度启动计时；或者
步骤S102-b：UE 102确定激活BWP2时目标定时器的第一计数，根据第一计数确定第二计数，控制目标定时器根据BWP2的单位计时长度从第二计数开始计时；或者
步骤S102-c：UE 102确定激活BWP2时目标定时器的第一计数，根据第一计数确定第三计数，控制目标定时器根据BWP2的单位计时长度和第三计数次执行计时；
步骤S102-d：UE 102控制目标定时器根据BWP2的单位计时长度，重新启动计时；或者
步骤S102-e：UE 102停止目标定时器的计时，或UE 102将目标定时器置为超时；
步骤S102-f：UE 102控制目标定时器根据BWP2的单位计时长度继续计时；
其中，目标定时器包括DRX重传定时器和/或DRX HARQ RTT定时器；
BWP1为用户设备激活BWP2之前，原本激活的部分带宽。
应注意，以上步骤S102-a、S102-b、S102-c、S102-d、S102-e和S102-f之间是择一执行的关系。这里的DRX重传定时器可以包括上行DRX重传定时器和下行DRX重传定时器；DRX HARQ RTT定时器可以包括上行DRX HARQ RTT定时器和下行DRX HARQ RTT定时器。
在上述步骤的实施中，若目标定时器为DRX重传定时器，则单位计时长度为时隙长度，从而根据UE 102为DRX重传定时器配置的时隙数量和单位计时长度，能够确定DRX重传定时器需要计时的时间长度；若目标定时器为DRX HARQ RTT定时器，则单位计时长度为符号长度，从而根据UE 102为DRX HARQ RTT定时器配置的符号数量和单位计时长度，能够确定DRX HARQ RTT定时器需要计时的时间长度。在实施中，BWP1的时隙长度和符号长度可以根据BWP1的子载波间隔的配置确定，BWP2的时隙长度和符号长度可以根据BWP2的子载波间隔的配置确定。
在步骤S101的实施中，UE 102所相应的第一消息可以是网络侧设备101向UE 102发送的用于指示UE 102将激活的BWP从已经激活的BWP1切换至BWP2的命令，或者是网络侧设备101向UE 102发送的用于指示UE 102激活新的BWP2同时保留BWP1的命令。具体来说，第一消息可以是PDCCH信令，也可以是MAC CE或者无线资源控制(RRC)消息。
在实施中，网络侧设备101可以在第一消息中携带BWP2的标识(identify，ID)，并由UE 102根据已知的BWP2的信息进行切换，例如，网络侧设备101还可以向网络侧设 备101发送第二消息，其中包括BWP2的信息，例如，第二消息可以是RRC重配置消息，其中可以包括BWP2的SCS信息、时隙长度信息和符号长度信息中的部分或全部，从而UE 102在收到第一消息后，可以根据已知的BWP2的信息，将激活的BWP切换到BWP2，或激活BWP2。另外，UE 102已经激活的BWP1的信息，也可以是网络侧设备101为UE102配置的，例如，网络侧设备101在向UE 102发送的第三消息中携带BWP1的信息，用于UE 102激活BWP1，其中，第三消息可以是RRC重配置消息，其中，BWP1的信息可以包括BWP2的SCS信息、时隙长度信息和符号长度信息中的部分或全部。在实施中，网络侧设备101还可以通过同一个消息(例如RRC重配置消息)，将BWP1的信息和BWP2的信息发送至UE 102，该消息中还可以包括其他的BWP的信息；UE 102在收到上述消息后，可以向网络侧设备101发送一个响应消息，以示反馈。
应注意，本申请实施例中也不排除由网络侧设备101通过第一消息向UE 102发送BWP2的信息，用于UE 102激活BWP2，例如，第一消息可以包括BWP2的SCS信息、时隙长度信息和符号长度信息中的部分或全部。或者，UE 102激活BWP2的步骤也可以是UE 102接收第四消息后，响应第四消息执行的，第四消息可以是网络侧设备101发送的。
在步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f的实施之前，UE 102还可以确定BWP1的单位计时长度和BWP2的单位计时长度之间的关系，以确定是否需要执行步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f。
具体来说，若UE 102根据第一消息，确定需要将已经激活的BWP1切换至BWP2，UE 102可以在BWP2的单位计时长度与BWP1的单位计时长度不同后，执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。其中，若UE 102确定BWP2的时隙长度与BWP1的时隙长度不同(即BWP2的时隙长度大于BWP1的时隙长度，或者BWP2的时隙长度小于BWP1的时隙长度)，则UE可以针对DRX重传定时器执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个，以确保DRX重传定时器不会提前超时，或者确保DRX重传定时器不会提前、滞后超时，避免UE 102用于DRX重传定时器的计数不准，出现通信异常；另外，在BWP1的时隙长度和BWP2的时隙长度不同时，BWP1的符号长度和BWP2的符号长度必然不同，因此UE 102在确定BWP2的时隙长度与BWP1的时隙长度不同后，还可以针对或只针对DRX HARQ RTT执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。若UE 102确定BWP2的符号长度与BWP1的符号长度不同，则UE可以执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个以确保DRX HARQ RTT定时器不会提前超时，或者确保DRX HARQ RTT定时器不会提前、滞后超时，避免UE 102用于DRX HARQ RTT定时器的计数不准出现通信异常；另外，在确定BWP2的符号长度与BWP1的符号长度不同后，UE 102还可以针对或只针对DRX HARQ RTT执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。
另外，若UE 102根据第一消息，确定需要激活BWP2，并同时通过BWP1和BWP2进行通信，UE 102可以在BWP2的单位计时长度大于BWP1的单位计时长度后，执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。其中，若UE 102确定BWP2的时隙长度大于BWP1的时隙长度，则UE可以针对DRX重传定时器执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个，以确保DRX重 传定时器不会提前超时，或者确保DRX重传定时器不会提前、滞后超时，避免UE 102用于DRX重传定时器的计数不准出现通信异常；另外，在BWP2的时隙长度大于BWP1的时隙长度时，BWP2的符号长度必然大于BWP1的符号长度，因此UE 102在确定BWP2的时隙长度与BWP1的时隙长度不同后，还可以针对或只针对DRX HARQ RTT执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。若UE 102确定BWP2的符号长度大于BWP1的符号长度，则UE可以针对DRX HARQ RTT执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个以确保DRX HARQ RTT定时器不会提前超时，或者确保DRX HARQ RTT定时器不会提前、滞后超时，避免UE 102用于DRX HARQ RTT定时器的计数不准出现通信异常；另外，在确定BWP2的符号长度大于BWP1的符号长度后，UE 102还可以针对或只针对DRX HARQ RTT执行上述步骤S102-a、S102-b、S102-c、S102-d、S102-e或者S102-f中的一个。
在步骤S102-a的实施中，UE 102可以在控制目标定时器继续根据BWP1的单位计时长度计时，并在目标定时器通知或者超时后，再次启动后控制目标定时器根据BWP1的单位计时长度计时。具体来说，UE 102可控制DRX重传定时器根据BWP1的时隙长度继续计时，直到DRX重传定时器停止计时或DRX重传定时器的计时超时，并在下次启动DRX重传定时器后，控制DRX重传定时器根据BWP2的时隙长度进行计时。其中，DRX重传定时器停止计时，可以是DRX重传定时器在UE 102的控制下停止计时。
一种实施方式为，若UE 102确定新激活的BWP2的时隙长度小于原本激活的BWP1的时隙长度，UE 102可以在激活BWP2后，控制DRX重传定时器根据BWP1的时隙长度继续计时，直到DRX重传定时器停止计时或DRX重传定时器的计时超时，并在重新启动DRX重传定时器后，控制DRX重传定时器根据BWP2的时隙长度进行计时；另外，若UE 102确定新激活的BWP2的时隙长度大于原本激活的BWP1的时隙长度，UE 102可以在激活BWP2后，控制DRX重传定时器根据BWP2的时隙长度继续计时，直到DRX重传定时器停止计时或DRX重传定时器的计时超时，并在重新启动DRX重传定时器后，控制DRX重传定时器根据BWP2的时隙长度进行计时。
举例来说，如图2所示，若UE 102配置DRX重传定时器计时的时隙数量为10个时隙，BWP1的时隙长度为1ms，则DRX重传定时器根据BWP1的时隙长度计时的时间长度应为10ms，假如UE 102激活BWP2时DRX重传定时器运行于8ms，此时根据步骤S102-a，UE 102可以继续根据1ms的时隙长度计时2ms至超时，此后，UE 102控制DRX重传定时器根据BWP2的时隙长度启动，若BWP2的时隙长度为0.5ms，DRX重传定时器计时的时间长度变更为5ms。在上例中，假如UE 102激活BWP2时DRX重传定时器运行于8ms(若根据BWP1的时隙长度计时，8ms的计数相对于10ms的时间长度尚未超时)，但DRX重传定时器根据BWP2的时隙长度计时的时间长度仅为5ms(8ms的计数相对于5ms的时间长度已经超时)，因此切换至BWP2时有可能导致DRX重传定时器超时而造成UE 102提前进入睡眠状态；但若UE 102仍然控制DRX重传定时器根据1ms的时隙长度计时，直至DRX重传定时器超时，则可以避免UE 102提前进入睡眠状态，也就不会影响正常通信。
另外，UE 102还可以控制DRX HARQ RTT定时器根据BWP1的符号长度继续计时，直到DRX HARQ RTT定时器停止计时或DRX HARQ RTT定时器的计时超时，并在下次启动DRX重传定时器后，控制DRX HARQ RTT定时器根据BWP2的符号长度进行计时。 其中，DRX HARQ RTT定时器停止计时，可以是DRX HARQ RTT定时器在UE 102的控制下停止计时。
在步骤S102-b的实施中，UE 102可以根据目标定时器的第一计数和调整倍率，确定目标定时器的第二计数，其中，调整倍率可以根据BWP2的单位计时长度和BWP1的单位计时长度确定，之后，UE 102可以控制目标定时器根据BWP2的单位计时长度从第二计数开始计时。
具体来说，若目标定时器为DRX重传定时器，UE 102可以确定激活BWP2时DRX重传定时器的第一计数，并根据第一计数和调整倍率确定第二计数，之后控制DRX重传定时器根据BWP2的时隙长度从第二计数开始计时(即从第二计数开始计时，直到DRX重传定时器计时终止，计时终止时的时间长度根据UE 102配置的时隙数量和BWP2的时隙长度确定)，其中，调整倍率可以根据BWP2的时隙长度与BWP1的时隙长度确定，或者根据BWP2的符号长度与BWP1的符号长度确定，例如，若调整倍率等于BWP2的时隙长度除以BWP1的时隙长度的比值，则第二计数等于第一计数乘以调整倍率；若调整倍率等于BWP1的时隙长度除以BWP2的时隙长度的比值，则第二计数等于第一计数除以调整倍率。
举例来说，如图2所示，若UE 102配置DRX重传定时器计时的时隙数量为10个时隙，BWP1的时隙长度为1ms，则DRX重传定时器根据BWP1的时隙长度计时的时间长度应为10ms，假如UE 102激活BWP2时DRX重传定时器运行于8ms，此时根据步骤S102-b，UE 102可以确定DRX重传定时器的计数为8ms，另外，UE 102可以确定BWP2的时隙长度为0.5ms，则BWP2的时隙长度和BWP1的时隙长度的比值为1:2，则UE 102可以确定第二计数为4(8*1/2)ms，并控制DRX重传定时器从4ms开始计时，且DRX重传定时器在计数为5ms时终止(由于UE 102配置DRX重传定时器计时的时隙数量为10个时隙，DRX重传定时器根据BWP2的时隙长度计时的时间长度为5ms，即DRX重传定时器的计数达到5ms时计时终止)。采用该方法，能够避免DRX重传定时器提前或滞后终止，避免影响正常通信。
相应地，在步骤S102-b的实施中，UE 102还可以确定DRX HARQ RTT定时器在UE102激活BWP2时的第一计数，以及确定调整倍率，用于确定第二计数，之后，UE 102可以控制DRX HARQ RTT定时器根据BWP2的符号长度，从第二计数开始计时。其中，调整倍率可以等于BWP2的时隙长度除以BWP1的时隙长度，第二计数为DRX重传定时器在UE 102激活BWP2时的计数乘以调整倍率；或者，调整倍率可以等于BWP1的时隙长度除以BWP2的时隙长度，第二计数为DRX重传定时器在UE 102激活BWP2时的计数除以调整倍率；另外，调整倍率还可以等于BWP2的符号长度除以BWP1的符号长度，第二计数为DRX重传定时器在UE 102激活BWP2时的计数乘以调整倍率；或者，调整倍率可以等于BWP1的符号长度除以BWP2的符号长度，第二计数为DRX重传定时器在UE 102激活BWP2时的计数除以调整倍率。
在步骤S102-c的实施中，第三计数可以为激活BWP2时目标定时器的剩余计时数，剩余计时数用于指示目标定时器在超时前根据BWP1的单位计时长度计时的剩余时隙数或剩余符号数，UE 102可以根据目标定时器的剩余单位计时长度和BWP1的剩余计时时长，确定第三计数，目标定时器的剩余计时时长可以是UE 102根据激活BWP2时目标定时器的第一计数确定的。则在确定第三计数后，UE 102可以控制目标定时器根据BWP2的单 位计时长度和根据第三计数计时，例如，控制目标定时器执行第三计数次的计数，每次计时的长度均为BWP2的单位计时长度。
具体来说，若目标定时器为DRX重传定时器，UE 102可以确定激活BWP2时DRX重传定时器的第一计数，并根据激活BWP2时DRX重传定时器的剩余计时时长除以BWP1的时隙长度得到第三计数，例如图2所示，若UE 102配置DRX重传定时器计时的时隙数量为10个时隙，BWP1的时隙长度为1ms，DRX重传定时器根据BWP1的时隙长度计时的时间长度应为10ms，假如UE 102激活BWP2时DRX重传定时器运行于4ms，此时根据步骤S102-c，UE 102可以确定DRX重传定时器的计数为4ms，即第一计数为4ms，DRX重传定时器剩余计时时长为2ms，UE 102将计时时长除以BWP1的时隙长度确定第三计数为2，则在激活BWP2之后，UE 102可以控制DRX重传定时器在4ms计数的基础上，继续执行2(2次*1ms)ms的计时。
相应地，在步骤S102-c的实施中，UE 102还可以确定DRX HARQ RTT定时器在UE102激活BWP2时的第一计数，以及确定第三计数，之后，UE 102可以控制DRX HARQ RTT定时器根据BWP2的符号长度，和根据第三计数进行计时。其中，第三计数可以根据激活BWP2时DRX HARQ RTT定时器的剩余计时时长除以BWP1的符号长度确定。
在步骤S102-d的实施中，UE 102可以在激活BWP2后，重启DRX重传定时器，并控制DRX重传定时器根据BWP2的时隙长度进行计时。
举例来说，如图2所示，若UE 102配置DRX重传定时器计时的时隙数量为10个时隙，BWP1的时隙长度为1ms，BWP2的时隙长度为0.5ms，则DRX重传定时器根据BWP1的时隙长度计时的时间长度应为10ms，假如UE 102激活BWP2时DRX重传定时器运行于8ms，此时根据步骤S102-c，UE 102重新启动DRX重传定时器的计时，并控制DRX重传定时器根据BWP2的0.5ms的时隙长度计时，即UE 102控制DRX重传定时器根据BWP2的时隙长度进行5ms时间长度的计时。采用该方案，在切换至BWP2后，由UE 102控制DRX重传定时器根据BWP2的时隙长度进行指定数量个时隙长度的完整计时，从而能够避免UE 102由于DRX重传定时器终止而提前进入睡眠模式，影响正常通信。
相应地，在步骤S102-c的实施中，UE 102还可以在激活BWP2后，重启DRX HARQ RTT定时器，并控制DRX HARQ RTT定时器根据BWP2的符号长度进行计时。
在步骤S102-e的实施中，UE 102可以在激活BWP2后，停止DRX重传定时器和/或DRX HARQ RTT定时器的计时；另外，UE 102还可以在激活BWP2后，将DRX重传定时器和/或DRX HARQ RTT定时器的计数置为超时。在实施中，在UE 102停止DRX重传定时器或者将DRX重传定时器置为超时后，UE 102可以不再监控检测PDCCH信道上网络侧设备101调度的该定时器对应的HARQ进程上重传的数据包。另外，在UE 102停止DRX HARQ RTT定时器或者将DRX HARQ RTT定时器置为超时后，UE 102可以启动对应该DRX HARQ RTT定时器的HARQ进程的DRX重传定时器，并在启动DRX重传定时器后，监听PDCCH信道获取该HARQ进程上调度的重传。
在步骤S102-f的实施中，UE 102还可以控制目标定时器根据BWP2的单位计时长度继续执行目标定时器的计时。
具体来说，若UE 102在激活BWP3后仍然保留BWP1，其中BWP3的时隙长度为2ms，BWP1的时隙长度为1ms，则UE 102在激活BWP3后，UE 102可以控制DRX重传定时器根据BWP1的时隙长度计时，和/或，UE 102控制DRX HARQ RTT定时器根据BWP1 的符号长度计时，以避免DRX重传定时器和/或DRX HARQ RTT定时器的提前超时。此时，若UE 102在激活BWP3后仍然控制DRX重传定时器根据BWP1的时隙长度计时，则在DRX重传定时器超时时，UE 102在BWP3监听的时隙数量尚未达到UE 102为DRX定时器配置的时隙数量，将导致DRX重传定时器提前超时，UE 102可能无法及时根据BWP3接收调度信息。
如图5所示，若UE 102根据网络侧设备101发送的第一消息，将已经激活的BWP1切换为BWP2，其中，BWP1的时隙长度为1ms，BWP2的时隙长度为0.5ms，本申请实施例提供的一种控制定时器的方法，具体包括如下步骤：
步骤501：UE 102根据网络侧设备101发送的RRC重配置消息，确定BWP1的时隙长度、符号长度和BWP2的时隙长度、符号长度；
步骤502：UE 102接收网络侧设备101发送的第一消息，第一消息指示UE 102将已经激活的BWP1切换为BWP2；
步骤503：UE 102响应第一消息，将已经激活的BWP1切换为BWP2；
步骤504：UE 102确定BWP1的时隙长度大于BWP2的时隙长度，之后执行步骤505-a、506-a、507-a、508-a或者509-a中的任意一个以调整DRX重传定时器，以及执行505-a、506-b、507-b、508-b或者509-b中的任意一个以调整DRX HARQ RTT定时器；
步骤505-a：UE 102控制DRX重传定时器根据BWP1的时隙长度计时，直到DRX重传定时器停止计时或DRX重传定时器的计时超时后，控制DRX重传定时器根据BWP2的时隙长度启动计时；
步骤505-b：UE 102控制DRX HARQ RTT定时器根据BWP1的符号长度计时，直到DRX HARQ RTT定时器停止计时或DRX HARQ RTT定时器的计时超时，控制DRX HARQ RTT定时器根据BWP2的符号长度启动计时；
步骤506-a：UE 102确定激活BWP2时DRX重传定时器的第一计数，根据BWP1的时隙长度除以BWP2的时隙长度得到调整倍率，根据第一计数除以调整倍率得到第二计数，控制DRX重传定时器根据BWP2的时隙长度从第二计数开始计时；
步骤506-b：UE 102确定激活BWP2时DRX HARQ RTT定时器的第一计数，根据BWP1的时隙长度除以BWP2的时隙长度得到调整倍率，根据第一计数除以调整倍率得到第二计数，控制DRX HARQ RTT定时器根据BWP2的符号长度从第二计数开始计时；
步骤507-a：UE 102确定激活BWP2时DRX重传定时器的第一计数，根据第一计数确定DRX重传定时器的剩余单位计时长度，根据剩余单位计时长度除以BWP1的时隙长度得到第三计数，控制DRX重传定时器进行第三计数次计时，其中每次单位计时长度等于BWP2的时隙长度；
步骤507-b：UE 102确定激活BWP2时DRX HARQ RTT定时器的第一计数，根据第一计数确定DRX HARQ RTT定时器的剩余单位计时长度，根据剩余单位计时长度除以BWP1的符号长度得到第三计数，控制DRX重传定时器进行第三计数次计时，其中每次单位计时长度等于BWP2的符号长度；
步骤508-a：UE 102控制DRX重传定时器根据BWP2的时隙长度，重新启动计时；
步骤508-b：UE 102控制DRX HARQ RTT定时器根据BWP2的符号长度，重新启动计时；
步骤509-a：UE 102停止DRX重传定时器的计时，或者将DRX重传定时器置为超时；
步骤509-b：UE 102停止DRX HARQ RTT定时器的计时，或者将DRX HARQ RTT定时器置为超时。
如图6所示，若UE 102根据网络侧设备101发送的第一消息激活BWP2，并保持已经激活的BWP1为激活状态，其中，BWP1的时隙长度为0.5ms，BWP2的时隙长度为1ms，本申请实施例提供的一种控制定时器的方法，具体包括如下步骤：
步骤601：UE 102根据网络侧设备101发送的RRC重配置消息，确定BWP1的时隙长度、符号长度和BWP2的时隙长度、符号长度；

基于与上述方法实施例相同构思，本申请实施例还提供了一种计算机程序产品，当所述计算机程序产品被计算机运行时，可以使得认证服务器执行上述方法实施例、方法实施例的任意一种可能的设计中所涉及的功能。
另外，本申请实施例还提供一种控制DRX激活时间的方法。
仍以图1所示的通信系统100为例，当UE 102工作在DRX模式，UE 102可能在某个时隙从网络侧设备101接收到DRX命令，该DRX命令用于指示UE 102进入睡眠状态。但是从网络侧设备101发送DRX命令的时隙开始，到网络侧设备101确定UE 102成功收到DRX命令的时隙之间的这段时间内为DRX模糊期，即这段模糊时期内网络侧设备101和UE 102都不能完全确定UE 102应该处于激活状态还是睡眠状态。根据本申请实施例提供的一种确定DRX模糊期的方法，网络侧设备101和UE 102能够准确确定DRX模糊期，以确定UE 102是否进入睡眠状态。
由于新空口(new radio，NR)中引入了新的跨slot调度，以及相关的混合自动重传请求反馈(hybrid automatic repeat request acknowledgement，HARQACk)机制，DRX的模糊期可以按照如下方式确定：DRX的模糊期包括下列中的部分或全部：PDCCH处理时延和跨slot调度时隙K0，PDCCH所调度的传输DRX命令的物理下行共享信道(physical downlink shared channel，PDSCH)的处理延迟和相应的HARQ-ACk反馈的处理延迟k，以及可选地还可以包括额外的1个slot。
其中，K0可以由网络侧设备101通过专用信令为UE 102配置，k可以从网络侧设备101发送的PDCCH调度信息中获得。其中，需要额外计算一个slot的原因是需要额外计算UE 102执行HARQ-ACk的一个slot，由于HARQ-ACk在该slot还没有成功发送到网络侧设备101，对于网络侧设备101而言，该slot上仍然不能确定UE 102是否一定处于激活或非激活的状态，所以为了降低网络侧设备101由于不能确定UE 102是否处于激活或非激活的状态而导致的对信道状态信息(channel state information，CSI)反馈信息和探测参考信号(sounding reference signalling，SRS)传输的盲检测带来的复杂性，而额外放松了 一个slot，也就是在UE发送HARQ-ACk的下一个slot，网络侧设备101可以明确确定UE102是否处于激活或非激活的状态。
据此，可以DRX模糊期确定为n-K0-k-1个slot。举例来说，如图11所示，网络侧设备101在slot n-K0-k-1发送了DRX命令，则DRX模糊期为slot n-K0-k-1至slot n，即在slot n时，UE 102判断自身处于激活状态还是睡眠状态，以及判断是否需要发送CSI或SRS，需根据slot n-K0-k-1时网络侧设备101发送的DRX命令以及其他的调度信息的传输决定。其中，其他调度信息的传输包括PDCCH指示的下行资源分配信息，UL资源分配信息或者UE发送的调度请求信息等。
为了方便UE 102实现，DRX模糊期可以根据下列中的部分或全部确定：n-K0-k，或者n-k-1，或者n-k，或者n-K0_max-k_max-1,或者，n-K0_max-k_max,或者n-k_max-1，或者n-k_max，其中，K0_max为NR系统中K0能取到的最大值，k_max为NR系统中k能取到的最大值。根据DRX模糊期，UE 102能够确定是否处于DRX非激活时间，例如，UE 102可以在第二时隙接收到DRX控制命令的PDCCH调度信息后，确定在第一时隙所述用户设备的MAC实体处于DRX非激活时间，其中，第二时隙与第一时隙之间的时隙偏移量即为DRX模糊期。
可选地，UE 102在时隙n-(K0+k+1)到时隙n之间，或时隙n-(K0+k)到时隙n之间可以执行CSI和/或SRS传输，也可以不执行CSI和/或SRS传输。
另外，若UE 102当前存在多个激活的BWP，且多个BWP具有不同的slot长度，如何确定模糊期的长度也是需要解决的问题。
在实施中，UE 102可以根据接收DRX命令的BWP对应的slot长度，然后根据n-K0-k-1确定模糊期长度。
或者，UE 102可以根据当前多个激活的BWP中，slot长度最大的BWP的slot长度，以及根据n-K0-k-1计算确定DRX模糊期长度。
基于以上确定DRX模糊期的方法，本申请实施例提供的一种控制DRX激活时间的方法包括：
用户设备确定在第一时隙所述用户设备的MAC实体处于DRX非激活时间内；
所述用户设备确定不执行SRS和/或CSI传输；

所述用户设备在第二时隙接收到DRX控制命令的PDCCH调度信息，所述DRX控制命令用于指示所述用户设备进入DRX非激活时间，所述第二时隙为所述第一时隙减去时隙偏移量，所述时隙偏移量等于如下任意一项：
K0+k；
K0+k+1；
k+1；
k；
n-K0_max-k_max-1；
n-K0_max-k_max；
n-k_max-1；
n-k_max；
其中，所述K0为所述第二时隙接收到的PDCCH调度信息与所述PDCCH调度信息所调度的PDSCH资源之间的间隔，所述k为所述用户设备针对所述PDSCH的接收时隙与所述用户设备执行HARQ反馈的时隙之间的间隔，K0_max为K0的最大值，k_max为k的最大值。
可选地，该方法还包括：
所述用户设备接收第一消息，所述第一消息中包含所述K0的值。
可选地，该方法还包括：
所述用户设备接收第二消息，所述第二消息中包含所述k的值。
可选地，该方法还包括：
