具体实施方式
如图1所示，在相关技术中，在LTE系统中，为了降低终端耗能，引入了DRX机制，即终端在处于连接态的时候，不需要连续监听基站的控制信道，而是间断的监听控制信道，其中，激活区间(On Duration)表示终端监听控制信道的时间段，而除去激活区间之外的其他时间则为非激活区间(Off Duration)，终端处于省电状态，其射频链路关闭。终端在配置的DRX周期起始处的激活区间唤醒执行连续PDCCH检测，而在非激活区间则不执行PDCCH检测，其中，DRX周期可以包括长周期(Long DRX Cycle)，或短周期(Short DRX Cycle)，在短周期内，On Duration出现的比长周期更加频繁，而当检测到该终端专属的PDCCH后，该UE被唤醒。如果没有检测到该终端专属的物理下行控制信道(PDCCH，Physical Downlink Control Channel)，并且DRX on定时器(drx-on DurationTimer)也超时，则该终端继续进入节能态；或者如果检测到该终端专属的PDCCH并启动/重启激活定时器(drx-InactivityTimer)，则该终端在激活定时器超时或收到DRX命令(Commond)，媒体接入控制(Medium Access Control，MAC)控制元素(Control Element，CE)，则该终端进入节能态。
由于终端仍然需要在DRX配置的周期时刻唤醒执行一段时间的盲检 PDCCH，同时在睡眠期间对于公有消息的接收也没有明确限制，因此亟需一种DRX机制增强方法来进一步提升终端节能。
下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
实施例一：
为了解决相关技术中终端仍然需要在DRX配置的周期时刻唤醒执行盲检PDCCH而产生耗能，同时在睡眠期间对于公有消息的接收也没有明确限制，所导致的DRX性能较为有限的问题，本实施例提供一种非连续接收DRX配置方法，请参见图2示出的接收配置方法的流程图：
S201：确定在非连续接收DRX周期内的第一时长内的指示信息检测结果。
其中，本实施例中的指示信息可以为物理层指示信息，终端可以在DRX唤醒态和DRX节能态之间进行转换，其中，DRX唤醒态也即在激活区间(On Duration)执行连续的PDCCH盲检测，而DRX节能态则是在非激活区间(Off Duration)执行非连续PDCCH盲检测，或则除了接收指示信息之外其余的信号或信道均不接收。
本实施例中的指示信息包括状态转换信道或状态转换信号，在状态转换信道或状态转换信号为单向状态转换信道或单向状态转换信号时，其中一种形式可以为唤醒信号和/或唤醒信道(WUS/WUP，Wake Up Signal/Wake Up PDCCH)，可以用于指示转入唤醒态，而在状态转换信道或状态转换信号为单/双向状态转换信道或单/双向状态转换信号时，其中一种形式则可以为包括L1信号和/或L1信道的L1信令，至少具有指示转入节能态(go to sleep)的功能，本实施例中的DRX周期由激活区间和非激活区间组成。应当说明的是，本实施例中的第一时长为指示信息的检测时长，其可以选择设置在DRX周期的激活区间和非激活区间中的任一种之内，或者也可以同时处于这两个区间之内。此外，应当理解的是，本实施例中的指示信息检测结果用于指示终端是否接收到指示信息。
S202：根据检测结果确定所需执行的DRX配置策略。
应当说明的是，本实施例中根据是否接收到指示信息来触发对应的DRX配置策略来对DRX性能进行增强。
S203：根据DRX配置策略进行DRX配置。
在本实施例的一些示例中，DRX配置策略包括：激活区间的DRX唤醒态配置策略、非激活区间的DRX节能态配置策略以及DRX唤醒态动态转入DRX 节能态配置策略中的至少一种。
其中，在本实施例中的DRX配置策略为激活区间的DRX唤醒态配置策略时，激活区间的DRX唤醒态配置策略包括以下至少一种：执行当前DRX周期或从当前往后的N个DRX周期的激活区间的PDCCH检测，在当前DRX周期或从当前往后的N个DRX周期的激活区间继续保持节能态；N取大于等于1的整数。
在本实施例的一些示例中，在DRX周期的激活区间内设置第一时长，第一时长的长度通过高层信令配置，第一时长的起始时刻与DRX周期相同，第一指示信息包括唤醒态指示信息，用于指示转入唤醒态，可以为唤醒信号和/或唤醒信道。那么，根据检测结果确定所需执行的DRX配置策略包括：在检测结果为检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为执行当前DRX周期或从当前往后的N个DRX周期的激活区间的PDCCH检测；在检测结果为未检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为在当前DRX周期或从当前往后的N个DRX周期的激活区间继续保持节能态。具体的请参阅图3，图3中的DRX周期所采用的是长周期(Long DRX Cycle)，其中T0表示第一时长，只有先在T0内检测到WUS/WUP，才执行在On Duration检测PDCCH，否则继续保持节能态。应当说明的是，第一时长可以小于或等于激活区间时长。
应当说明的是，请继续参阅图3，作为本实施例中的一种示例，第一指示信息如唤醒信号和/或唤醒信道的配置周期与DRX周期相同，也即每两个T0的同一参考时刻之间所间隔的时长与每两个DRX周期的同一参考时刻之间所间隔的时长相同，当然在另一些实施方式中，第一指示信息的配置周期也可以大于或小于DRX周期，可视具体应用场景灵活设置。
并且，本实施例中在配置T0时，可以共用DRX配置时的一些参数，例如周期、偏移等，仅需额外配置部分参数。
还应当说明的是，本实施例中的第一时长可以包括：传输第一指示信息所需时长、节能态转入唤醒态所需时长以及第一指示信息的应答反馈时长中的至少一种。
此外，在本实施例的一些示例中，在DRX配置策略为激活区间的DRX唤醒态配置策略时，激活区间的DRX唤醒态配置策略包括以下至少一种：在后续至少一个DRX周期的激活区间保持节能态；执行后续至少一个DRX周期的激活区间的PDCCH检测。
在本实施例的一些示例中，在DRX周期的非激活区间内设置第一时长，第 一时长的长度通过高层信令配置，第一时长小于或等于非激活区间时长，第一指示信息包括唤醒态指示信息，用于指示终端指示转入唤醒态，例如可以为唤醒信号和/或唤醒信道。那么，根据检测结果确定所需执行的DRX配置策略包括：在检测结果为检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测；在检测结果为未检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为在后续至少一个DRX周期的激活区间继续保持节能态。具体的请参阅图4，图4中的DRX周期所采用的是长周期(Long DRX Cycle)，其中T0表示第一时长，只有先在T0内检测到WUS/WUP，才执行在下一个DRX周期的on duration检测PDCCH，否则继续保持节能态。应当说明的是，第一指示信息的配置周期可以与DRX周期相同，第一指示信息所在第一时长的起始时刻可以根据预设的偏移值确定。应当理解的是，本实施例中可以将偏移值确定为DRX周期的长度与第一时长的长度的差值，也即将第一时长的终止时刻与下一个DRX周期的起始时刻相同。当然在另一些实施例中，也可以将第一时长的终止时刻与下一个DRX周期的起始时刻间隔一定时长设定。
另外，本实施例中也可以将第一指示信息与DRX周期独立配置，也即T0与DRX周期为无关的两套配置，与图4中所不同的是，本实施例中的T0的终止时刻与下一个DRX周期的起始时刻之间间隔一定时长，并且在第一指示信息的配置周期比DRX周期小的情况下，在一个DRX周期可以出现多个T0，提升了T0的设置密度。
另外，如图3和图4中所示出的是T0内传输的1个WUS/WUP对应一个DRX周期的唤醒，当然也可以图5中所示出的1个WUS/WUP对应后续N个DRX周期的唤醒，即指示终端是否需要在后续X个DRX周期的执行on duration的PDCCH检测，其中，X为预设或配置或动态指示的取值，图5中所示出的X取2。
应当说明的是，在本实施例的一些示例中，第一时长的起始时刻和结束时刻分别位于不同的DRX周期内，也即用于进行指示信息的第一时长同时处于当前DRX周期的非激活区间及下一DRX周期的激活区间内，从而第一时长的起始时刻处于当前DRX周期的非激活区间，然后一直延续至下一DRX周期的激活区间，并将第一时长的结束时刻设置在该激活区间内，第一时长的长度通过高层信令配置，这种情况下，第一指示信息中具有唤醒态指示信息。那么，根据检测结果确定所需执行的DRX配置策略包括：在检测结果为在当前DRX周期的非连续检测区间检测到第一指示信息如唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测；在检测结果为未检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX 配置策略为在后续至少一个DRX周期的激活区间继续保持节能态。而在检测结果为在下一DRX周期的连续检测区间检测到第一指示信息如唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测；在检测结果为未检测到唤醒信号和/或唤醒信道时，确定所需执行的DRX配置策略为在后续至少一个DRX周期的激活区间继续保持节能态。
还在本实施例的一些示例中，在DRX周期的非激活区间内设置第一时长；第一时长小于或等于非激活区间时长，第二指示信息包括节能态指示信息，用于指示终端转入节能态，例如可以为包括L1信号和/或L1信道的L1信令。那么，根据检测结果确定所需执行的DRX配置策略包括：在检测结果为检测到指示终端转入节能态的L1信令时，确定所需执行的DRX配置策略为执行在后续至少一个DRX周期的激活区间继续保持节能态；在检测结果为未检测到该L1信令时，确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测。具体的请参阅图6，图6中的DRX周期所采用的是长周期(Long DRX Cycle)，其中L1所指位置表示第一时长，只有先在信息检测时长内检测到指示终端转入节能态L1信令，则表示进入节能态，并直至下一次检测L1之前，均保持节能态不执行PDCCH盲检。
应当说明的是，图6示出了指示L1信令的检测时长等于DRX周期的情况，在这种情况下，为检测时长配置不同的偏移值或者与下一DRX周期的起始时刻的Gap值，Gap大于等于0，此时每个DRX周期起始之前唯一对应一个L1信号和/或L1信道。而在另一些实施方式中，也可以分别如图7和图8中所示，将L1信令的检测时长分别设置为大于、小于DRX周期。
在本实施例中的一种示例中，在包括节能态指示信息的第二指示信息的配置周期小于DRX周期时，确定在DRX周期内所设置的多个第一时长内的指示信息检测结果之后，根据最后一个检测结果确定所需执行的DRX配置策略。具体的请再次参阅图8，每一DRX周期内配置有两个第一时长，此时若在前一个时长内检测到指示终端转入节能态的第二指示信息，而在后一个时长内未检测到，则以所检测到第二指示信息的前一个时长的检测结果确定DRX配置策略，而在另一种情况下，若在后的时长内检测到该指示信息，则不论在前的时长内是否检测到该指示信息，均以在后的时长的检测结果确定DRX配置策略。
此外，在本实施例的一种示例中，指示信息还包括激活区间的长度指示信息；激活区间的DRX唤醒态配置策略还包括：激活区间的的长度指示策略。在这种情况下，指示信息除了可以指示所需转入的状态之外，还可以对激活区间的长度进行指示，WUS/WUP或具有指示唤醒的功能的L1信号和/或信道指示唤 醒时长或者唤醒定时器门限值，此时处于唤醒态的时长可以由WUS/WUP或具有指示唤醒的功能的L1信号和/或L1信道指示的唤醒时长确定，或者通过由WUS/WUP或具有指示唤醒的功能的L1信号和/或L1信道指示的唤醒定时器超时确定。其中，作为一种实施方式，终端成功检测到专属PDCCH后重启唤醒定时器。即此时新指示的唤醒时长或者唤醒定时器替代之前配置的激活定时器。另外，所述WUS/WUP还指示带宽部分(BandWidth Part，BWP)切换/时隙格式指示(Slot Format Indication，SFI)等信息。
应当说明的是，在DRX配置策略为激活区间的DRX唤醒态配置策略时，在确定在DRX周期内第一时长内的指示信息检测结果之后，还包括：根据检测结果确定是否在第一时长内未接收到指示信息；若未接收到指示信息，则在DRX周期内设置第二时长作为漏检补偿时长；在该第二时长内再次进行指示信息检测。
在实际应用中，若基站在第一时长内发送了指示信息，但是没有接收到终端的ACK/NACK应答反馈，或者没有收到后续调度的物理下行共享信道(PDSCH：Physical Downlink Shared Channel)的ACK/NACK应答反馈，为避免终端和基站之间的歧义理解，则基站在终端的DRX周期内预设/配置的周期位置再次发送指示终端转入唤醒态的指示信息。对应的，如果终端在第一时长内没有收到该指示信息，则终端在DRX周期内以预设/配置的周期再次尝试接收指示信息。更进一步的，如果终端在第一时长内检测到指示信息，或者在DRX周期内再次检测到指示信息，则不需要在DRX周期内继续检测指示信息。
本实施例的一种示例中，在第二时长内进行指示终端转入唤醒态的指示信息检测之后，还包括：若在第二时长内检测到指示信息，则将激活区间的起始时刻调整至在第二时长内检测到指示信息的时刻。
以上实施例通过对DRX唤醒态的优化，使得终端在没有业务传输需求的时候无需每个DRX周期都唤醒执行PDCCH盲检，提升终端节能效果，保证终端以低能耗工作。
另外，在本实施例中的DRX配置策略为非激活区间的DRX节能态配置策略时，非激活区间的DRX节能态配置策略包括以下至少一种：执行当前DRX周期或从当前往后的M个DRX周期的非激活区间的PDCCH检测，在当前DRX周期或从当前往后的M个DRX周期的非激活区间继续保持节能态；M取大于等于1的整数。
在本实施例的一种示例中，确定在DRX周期内的非激活区间内所设置的预设时长的第一时长内的指示信息检测结果；第一时长的长度通过高层信令配置，第一时长小于或等于非激活区间时长，第一指示信息包括唤醒态指示信息；并 在检测结果为检测到该第一指示信息时，确定所需执行的DRX配置策略为执行当前DRX周期或从当前往后的M个DRX周期的非激活区间的PDCCH检测；在检测结果为未检测到该第一指示信息时，确定所需执行的DRX配置策略为在当前DRX周期或从当前往后的M个DRX周期的非激活区间继续保持节能态。
其中一种实现方式是，独立配置仅在DRX off期间执行WUS/WUP检测的WUS/WUP周期。在Off Duration期间，一旦在WUS/WUP周期时刻检测到WUS/WUP，则终端继续执行PDCCH盲检，执行时长可以为DRX on duration定时器的门限值。可选的，独立配置仅在DRX 0ff期间执行WUS/WUP检测的WUS/WUP周期，例如与DRX周期配置相同且仅在DRX off的起始位置。
另一种实现方式是，在DRX off期间，一旦在L1信令周期时刻检测到具有唤醒态指示信息的L1信令，则终端继续执行PDCCH盲检，执行时长为DRX on duration定时器的门限值。
以上实施例通过对DRX节能态的优化，使得终端在DRX节能态有唤醒机会，进而实现低时延高可靠与节能之间的折中。
此外，在DRX配置策略为DRX唤醒态动态转入DRX节能态配置策略时，在本实施例的一些示例中，确定在DRX周期的激活区间内所设置的预设时长的第一时长内的第三指示信息检测结果；第一时长的长度通过高层信令配置，第一时长小于或等于激活区间时长，第三指示信息同时包括节能态指示信息和唤醒态指示信息，例如既可用于指示转入节能态又可用于指示转入唤醒态的、具备双向状态转换指示功能的L1信令，并在检测结果为检测到该L1信令时，确定所需执行的DRX配置策略为执行在当前DRX周期或从当前往后的多个DRX周期的激活区间继续保持节能态。在On Duration期间一旦在L1信令周期时刻检测到L1信令且指示进入节能态，则终端进入节能态或者进入深度节能态(深度节能态为仅保留检测L1信令的能力)。另外，该L1信令也可以指示间隔时间T后进行节能态，T值可以为预设的或无线资源控制(Radio Resource Control，RRC)配置的多个值中的一个值。
还在本实施例的另一些示例中，确定在DRX周期的激活区间内所设置的预设时长的第一时长内的第四指示信息检测结果；第一时长小于或等于激活区间时长，第四指示信息则包括对调度单播业务下行控制信息(Downlink Control Information，DCI)的物理下行控制信息中增加唤醒态指示信息；在检测结果为检测到DCI时，确定所需执行的DRX配置策略为执行在当前DRX周期或从当前往后的多个DRX周期的激活区间继续保持节能态。该第四指示信息可以通过对调度单播业务的DCI中引入1bit指示后续无需接收检测PDCCH。此时在DRX on期间，一旦检测到调度单播业务的DCI中该1bit所指示的后续无需接收检测 PDCCH，则由On Duration转入Off Duration。
以上实施例通过支持DRX唤醒态动态转入DRX节能态的优化，使得终端仅通过接收检测L1信令就可以转入DRX节能态，进而更加灵活的实现节能。
此外，还应当说明的是，当指示转入唤醒态的指示信息例如唤醒信号和/或唤醒信道(WUS/WUP)与DRX同时配置时，优先级规则包括以下至少之一：
方式一：当唤醒信号WUS与DRX同时配置时：当WUS所在BWP无法支持PDCCH传输时，则当WUS优先级高时，则DRX进入节能态仍然允许通过WUS唤醒；当DRX优先级高时，在处于WUS监测期间所在BWP无法支持PDCCH传输，DRX无法周期唤醒执行，或者切换至默认的(default)BWP执行DRX唤醒态检测PDCCH，在DRX节能态期间不能通过WUS唤醒终端。当WUS所在BWP可以支持PDCCH传输时，则当WUS优先级高时，则DRX进入节能态仍然允许通过WUS唤醒；当DRX优先级高时，在处于WUS检测期间但没有检测到WUS时仍然可以在DRX唤醒态期间唤醒执行PDCCH检测，在DRX节能态期间不能通过WUS唤醒终端。
方法二：当唤醒信道WUP与DRX同时配置时：当WUP优先级高时，则DRX进入节能态仍然允许通过WUP唤醒；当DRX优先级高时，在处于WUP检测期间但没有检测到WUP时仍然可以执行DRX唤醒检测PDCCH，在DRX节能态期间不能通过WUP唤醒终端。
方法三：当WUS/WUP与DRX同时配置时：当WUS所在BWP无法支持PDCCH传输时，则当WUS/WUP优先级高时，则DRX进入节能态仍然允许通过WUS/WUP唤醒；当DRX优先级高时，在处于WUP检测期间但没有检测到时仍然可以执行DRX唤醒检测PDCCH，在DRX节能态期间不能通过WUP唤醒终端，在处于WUS监测期间所在BWP无法支持PDCCH传输，DRX无法周期唤醒执行，或者切换至default BWP执行DRX唤醒态检测PDCCH，在DRX节能态期间不能通过WUS唤醒终端。当WUS所在BWP可以支持PDCCH传输时，则当WUS/WUP优先级高时，则DRX进入节能态仍然允许通过WUS/WUP唤醒；当DRX优先级高时，在处于WUS/WUP检测期间但没有检测到时仍然可以在DRX唤醒态期间唤醒执行PDCCH检测，在DRX节能态期间不能通过WUS/WUP唤醒终端。
通过确定不同节能机制的优先级，使得终端和基站避免歧义理解，进而保证不同节能机制的共存。
由于通过本发明实施例提供的接收配置方法，通过确定在DRX周期内的第一时长内的指示信息检测结果，DRX周期包括激活区间和非激活区间；根据检 测结果确定所需执行的DRX配置策略；根据DRX配置策略进行DRX配置。在引入指示信息的情况下，通过对指示信息进行检测来配置DRX，实现了DRX性能的优化。
实施例二：
本实施例提供一种接收控制方法，请参见图9示出的接收控制方法的流程图：
S901：向终端发送指示信息；指示信息的发送情况用于指示终端确定DRX配置策略。
S902：接收终端基于在DRX周期内的第一时长内，检测到指示信息后所发送的应答信息；DRX周期包括激活区间和非激活区间。
在本申请的一些示例中，基站向终端发送指示信息，其中，唤醒信号和/或唤醒信道(WUS/WUP，Wake Up Signal/Wake Up PDCCH)可以用于指示转入唤醒态，而L1信令则包括L1信号和/或信道，至少具有指示转入节能态(go to sleep)的功能，在终端在DRX周期内所设置的第一时长内接收到该指示信息后，则根据该指示信息进行对应DRX配置策略的确定，然后由终端向基站返回对应的应答信息，此时基站才会制定对应的PDCCH发送策略，决定是否或何时在终端的激活区间(On Duration)发送调度终端的单播业务的PDCCH。
进一步的，在向终端发送指示信息之后，还包括：若未接收到终端发送过来的应答信息，则在终端DRX周期内的第二时长内继续向终端发送指示信息。
在本申请的一些示例中，若基站在第一时长内发送了指示信息，但是没有接收到终端的ACK/NACK应答反馈，或者没有收到后续调度的物理下行共享信道(PDSCH：Physical Downlink Shared Channel)的ACK/NACK应答反馈，为避免终端和基站之间的歧义理解，则基站在终端的DRX周期内预设/配置的周期位置再次发送WUS/WUP。对应的，如果终端在第一时长内没有收到指示信息，则终端在DRX周期内以预设/配置的周期再次尝试接收指示信息。
由于通过本发明实施例提供的接收控制方法，在引入指示信息的情况下，通过基站向终端发送该指示信息以控制终端根据指示信息配置DRX，通过对终端DRX唤醒态的优化，使得终端在没有业务传输需求的时候无需每个DRX周期都唤醒执行PDCCH盲检，提升终端节能效果，保证终端以低能耗工作。
实施例三：
如图10所示为本实施例提供的通信系统的结构示意图，该通信系统包括接收配置装置110和接收控制装置120，接收配置装置110和接收控制装置120用于进行指示信息的交互，以及PDCCH的调度与检测。

并且，本实施例中在配置T0时，可以共用DRX配置时的一些参数，例如周期、偏移等，仅需额外配置部分参数。
还应当说明的是，本实施例中的第一时长可以包括：传输第一指示信息所需时长、节能态转入唤醒态所需时长以及第一指示信息的应答反馈时长中的至少一种。

在本实施例的一些示例中，在DRX周期的非激活区间内设置第一时长，第一时长的长度通过高层信令配置，第一时长小于或等于非激活区间时长，第一指示信息包括唤醒态指示信息，用于指示终端指示转入唤醒态，例如可以为唤醒信号和/或唤醒信道。那么，在检测结果为检测到唤醒信号和/或唤醒信道时，策略确定模块1101确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测；在检测结果为未检测到唤醒信号和/或唤醒信道时，策略确定模块1101确定所需执行的DRX配置策略为在后续至少一个DRX周期的激活区间继续保持节能态。应当说明的是，本实施例中也可以将唤醒信号和/或唤醒信道周期与DRX周期独立配置，也即T0与DRX周期为无关的两套配置。
还在本实施例的一些示例中，在DRX周期的非激活区间内设置第一时长；第一时长小于或等于非激活区间时长，第二指示信息包括节能态指示信息，用于指示终端转入节能态，例如可以为包括L1信号和/或信道的L1信令。那么，在检测结果为检测到指示终端转入节能态的L1信令时，策略确定模块1101确定所需执行的DRX配置策略为执行在后续至少一个DRX周期的激活区间继续保持节能态；在检测结果为未检测到该L1信令时，策略确定模块1101确定所需执行的DRX配置策略为执行后续至少一个DRX周期的激活区间的PDCCH检测。应当说明的是，在本实施例中的一种示例中，在具有节能态指示信息的指示信息的配置周期小于DRX周期时，策略确定模块1101确定在DRX周期内所设置的多个预设时长的第一时长内的指示信息检测结果之后，策略确定模块1101根据最后一个检测结果确定所需执行的DRX配置策略。
此外，更进一步的，指示信息还包括激活区间的长度指示信息；激活区间的DRX唤醒态配置策略还包括：激活区间的的长度指示策略。在这种情况下， 指示信息除了可以指示所需转入的状态之外，还可以对激活区间的长度进行指示，WUS/WUP或具有指示唤醒的功能的L1信号和/或L1信道指示唤醒时长或者唤醒定时器门限值，此时处于唤醒态的时长可以由WUS/WUP或具有指示唤醒的功能的L1信号和/或L1信道指示的唤醒时长确定，或者通过由WUS/WUP或具有指示唤醒的功能的L1信号和/或L1信道指示的唤醒定时器超时确定。其中，作为一种实施方式，终端成功检测到专属PDCCH后重启唤醒定时器。即此时新指示的唤醒时长或者唤醒定时器替代之前配置的激活定时器。另外，所述WUS/WUP还指示BWP切换/SFI等信息。
应当说明的是，在本实施例的一些示例中，还包括：漏检补偿模块，用于根据检测结果确定是否在第一时长内未接收到指示信息；若未接收到指示信息，则在DRX周期内设置第二时长作为漏检补偿时长；在该第二时长内再次进行指示信息检测。进一步的，还包括：激活区间调整模块，用于在第二时长内检测到指示信息时，将激活区间的起始时刻调整至在第二时长内检测到指示信息的时刻。
以上实施例通过对DRX唤醒态的优化，使得终端在没有业务传输需求的时候无需每个DRX周期都唤醒执行PDCCH盲检，提升终端节能效果，保证终端以低能耗工作。
另外，在本实施例中的DRX配置策略为非激活区间的DRX节能态配置策略时，非激活区间的DRX节能态配置策略包括执行当前DRX周期或从当前往后的M个DRX周期的非激活区间的PDCCH检测，和/或在当前DRX周期或从当前往后的M个DRX周期的非激活区间继续保持节能态，M取大于等于1的整数。

以上实施例通过对DRX节能态的优化，使得终端在DRX节能态有唤醒机会，进而实现低时延高可靠与节能之间的折中。
此外，在本实施例的一些示例中，策略确定模块1101确定在DRX周期的激活区间内所设置的预设时长的第一时长内的指示信息检测结果；第一时长的 长度通过高层信令配置，第一时长小于或等于激活区间时长，第三指示信息同时包括节能态指示信息和唤醒态指示信息，例如既可用于指示转入节能态又可用于指示转入唤醒态的、具备双向状态转换指示功能的L1信令，并在检测结果为检测到该L1信令时，策略确定模块1101确定所需执行的DRX配置策略为执行在当前DRX周期或从当前往后的多个DRX周期的激活区间继续保持节能态。
还在本实施例的另一些示例中，在DRX配置策略为DRX唤醒态动态转入DRX节能态配置策略时，策略确定模块1101确定在DRX周期的激活区间内所设置的预设时长的第一时长内的指示信息检测结果；第一时长小于或等于激活区间时长，第四指示信息则包括对调度单播业务DCI的物理下行控制信息中增加唤醒态指示信息；在检测结果为检测到DCI时，策略确定模块1101确定所需执行的DRX配置策略为执行在当前DRX周期或从当前往后的多个DRX周期的激活区间继续保持节能态。
以上实施例通过支持DRX唤醒态动态转入DRX节能态的优化，使得终端仅通过接收检测L1信令就可以转入DRX节能态，进而更加灵活的实现节能。
请参考图12，图12为本实施例提供的一种接收控制装置120的结构示意图，应用于基站，包括：
发送模块1201，用于向终端发送指示信息；指示信息的发送情况用于指示终端确定DRX配置策略。
接收模块1202，用于接收终端基于在DRX周期内预设的第一时长内，检测到指示信息后所发送的应答信息；DRX周期包括激活区间和非激活区间；
在本实施例的一些示例中，发送模块1201向终端发送指示信息，其中，唤醒信号和/或唤醒信道(WUS/WUP，Wake Up Signal/Wake Up PDCCH)可以用于指示转入唤醒态，而L1信令则包括L1信号和/或L1信道，至少具有指示转入节能态(go to sleep)的功能，在终端在DRX周期内所设置的预设时长的第一时长内接收到该指示信息后，则根据该指示信息进行对应DRX配置策略的确定，然后由终端向接收模块1202返回对应的应答信息，此时基站才会制定对应的PDCCH发送策略，决定是否或何时在终端的激活区间(On Duration)发送调度终端的单播业务的PDCCH。
