当用户设备进行非连续接收节能是，用户设备可以周期性的运行DRX on timer，在DRX on timer的运行中用户设备处于活跃状态，需要进行下行控制信道的检测和接收等操作；当DRX on timer过期，用户设备可以转为非活跃状态，不需要进行下行接收操作。DRX on timer的起始时间、周期、运行时间等可以根据预配置或者基站配置得到，不属于本专利的内容，在此不再赘述。
然而，接收用户设备的DRX操作会影响发送用户设备的资源选择，如果发送用户设备选择的发送资源落在接收用户设备的DRX off时间段上，接收用户将无法收到直连传输。如果发送端用户设备无法对接收端的DRX进行控制和调整，发送端用户设备需要保证其直连传输所选择的时间频率资源处于接收端用户设备的活跃时间段内。
但是，额外的资源选择限制会增加所选择的资源受到较强干扰的可能性，降低系统性能。此外，发送端用户设备可能无法确保预留的时频率资源也一定处于接收端的活跃时间内。
因此，本发明提出了一种发送端端用户设备可以对接收端用户设备的DRX进行控制和调整的方案。
下面参照附图描述本发明实施例的直连通信控制方法、装置、设备及其存储介质，其中，为了描述的方便，分别集中在发送设备侧和接收设备侧描述，其中，发送设备和接收设备分别是直连数据通信的发送端用户设备和接收端用户设备，其中，发送设备和接收设备可以为移动终端等。
下面首先集中在发送设备侧进行描述。
图1是根据本发明实施例提供的一种直连通信控制方法的流程图，其中，包括：
步骤101，发送直连控制信令，其中，直连控制信令包括控制接收设备的非连续接收DRX的第一指示信息。
在本实施例中，发送设备发送包含控制接收设备进行非连续接收DRX的有关操作的第一指示信息，从而，以便于发送设备直接指示接收设备的非连续接收DRX操作，避免发送端设备无法确保预留资源一定处于接收设备的活跃时间内，平衡了节能和系统性能。
应当理解的是，上述发送设备的预留资源可以为用于指示未来在直连传输通信时，发送设备预留的时间频率的资源位置等。本发明的目的，是为了使得接收设备可以在预留时频资源之前进入到活跃状态。
需要说明的是，在不同的应用场景中，可以不同的方式实现直连控制信令的传输，作为一种可能的实现方式，直连控制信令为物理层直连控制信息(sidelink control information-SCI)，即通过物理层直连控制信息实现直连控制信令的传输；作为另一种可能的实现方式，直连控制信令为介质访问控制控制单元MAC CE，即可以通过MAC层控制单元实现直连控制信令的传输。
综上，本发明实施例的直连通信控制方法，发送设备直接向用户设备发送直连控制信令，其中，直连控制信令包括控制接收设备的非连续接收DRX的第一指示信息。由此，避免发送设备无法确保预留资源一定处于接收设备的活跃时间内，平衡了节能和系统性能。
在实际执行过程中，为了便于平衡节能和系统性能，发送设备向用户设备发送携带控制接收设备进行非连续接收DRX的有关操作的第一指示信息，可以包含任意可以使得发送设备和接收设备资源可以对接成功的指示内容。
下面主要集中在三种可能的第一指示信息的指示内容上进行示例说明：
第一种：
在本实施例中，第一指示信息，包括指示：接收设备进入活跃状态的时刻的信息，从而，使得发送设备预留好接收设备进入活跃状态的资源等。
在一些可能的示例中，直连控制信令为物理层直连控制信息，物理层直连控制信息中包括：为未来直连传输所预留的时间频率资源位置的第二指示信息，其中，预留的时间频率资源位置的第二指示信息还用于指示接收设备进入活跃状态的时刻，由此，接收设备在所预留时频率资源之前进入活跃的接收状态，避免能耗，提高系统性能。
其中，指示所述接收设备进入活跃状态的时刻的第二指示信息可以包含不同的内容：
示例一：
在本实施例中，预留的时间频率资源位置的指示信息也指示接收设备进入活跃状态的时刻，包括：在预留的时间频率资源位置之前T时间进入活跃状态，以确保接收设备需要在发送设备所预留时频率资源之前T时间进入活跃接收状态。
其中，这里在T时间之前指在预留时频率资源的某个参考时间位置之前T时间。例如参考时间位置为时频率资源的起始OFDM symbol位置，或，预留时频率资源所在的slot等等；T的单位可以是物理时间单位，也可以是逻辑时间单位，例如，秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
在一些可能的实施例中，T的取值范围包括0，可以是固定值；也可能取值由设备的能力决定的；或者，可以通过接收基站等网络侧发送的下行信令，或者，通过读取预配置信息确定T的信息，该T的信息包括上述提到的T的取值或者是取值范围。
其中，也可以为T(预)配置一组值，通过物理层控制信息指示具体取哪一个值，即在物理层控制信息中包括指示T的信息，该T的信息包括上述提到的T的取值或者是取值范围。正如以上提到的，在一些可能的中，物理层控制信息中包含第二指示信息是否用于指示接收设备是否进入活跃状态的时刻，也可以理解，该物理层控制信息中，包含第二指示信息是否用于指示接收设备是否进入活跃状态的指示，比如，若是该物理层控制信息中,，表示第二指示信息是否用于指示接收设备是否进入活跃状态的指示的信息位的信息为1，则表示第二指示信息用于指示接收设备是否进入活跃状态，若是信息位的信息为0，则表示第二指示信息不用于指示接收设备是否进入活跃状态。
例如，在1st stage SCI中或对应的2nd stage SCI中携带指示T的取值的指示信息，接收设备在根据1st stage SCI中的预留时频率资源信息进入活跃状态时，使用1st stage SCI或对应2nd stage SCI中指示的T的取值。
示例二：
在本实施例中，预留的时间频率资源位置的第一指示信息，包括：指示接收设备进入活跃状态的时刻的偏移值的信息，以确保接收设备需要在发送设备所预留时频率资源之前进入活跃接收状态。
在一些可能的实施例中，可以通过接收基站等网络侧发送的下行信令，或者，通过读取预配置信息确定得到接收设备进入活跃状态时刻的偏移值的信息，该偏移值的信息包括偏移值的取值或者取值范围，例如，配置的偏移值为{-8，-4,-2， 0,2，4,8}，通过3比特指示具体使用哪个偏移值。
在本实施例中，可以在直连控制信令中指示是否携带进入活跃状态时刻的偏移值，接收设备根据接收到的偏移值指示调整下一周期进入活跃状态的时间。例如，指示的偏移值为-4slot，那么接收设备在下一个周期提前4个slot进入活跃状态；如果指示的偏移值为2slot，那么接收设备延后2个slot进入活跃状态。这里和之后指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
例如，接收设备根据当前的帧号，slot号判断启动DRX on timer的时间，当(DFN*1个Frame里的slot数目+当前slot号)％(DRX周期)＝(配置offset)％(DRX周期)时才启动DRX on timer，其中DFN为sidelink的帧号，DRX周期和配置offset为基站配置或预配置值。
即在本实施例中，当接收到携带偏移指示的SCI或MAC CE后，接收设备根据如下公式判断下一次启动DRX on timer的时间，公式为：
(DFN*1个Frame里的slot数目+当前slot号)％(DRX周期)＝(配置offset+偏移指示)％(DRX周期)。这里偏移指示为携带的指示的偏移值。
可以在物理层直连控制信息SCI中包含本次传输是否携带偏移指示的指示，也可以通过不同的直连控制信令格式隐式指示本次直连控制信令传输是否携带偏移指示。例如，定义不同的2nd stage SCI格式，只有当选择特定的2nd stage SCI时，物理层直连控制信息中才包含偏移指示的信息域。
物理层直连控制信息或MAC层控制单元中携带的偏移指示可以只适用于下一个DRX周期，也可以适用于之后的一段时间内的DRX周期，或者使用于之后所有的DRX周期。当适用于之后一段时间内的DRX周期时，一段时间的长度可以通过基站配置或预配置的方法决定。
当接收设备在一个DRX周期接收到多个携带偏移指示的直连控制信令的时候，接收设备使用最后接收到的一个偏移指示。
第二种：
在本示例中，控制接收设备进行非连续接收DRX的第一指示信息，包括：接收设备进入活跃状态的时间长度的信息。
在一些可能的示例中，指示接收设备进入活跃状态的时间长度的指示，包括：指示接收设备进入活跃状态时间长度改变的偏移值，或者，指示接收设备进入活跃状态时间长度的取值。
在本实施例中，可以在直连控制信令中包含本次传输是否携带偏移指示的指示，也可以通过不同的直连控制信令格式隐式指示本次传输是否携带偏移指示。其中，该偏移指示用于指示是否携带接收设备进入活跃状态的时间长度的指示信息。
需要说明的是，在不同的场景中，时间长度的指示信息可以包含不同的内容：
示例一：
在本示例中，指示接收设备进入活跃状态时间长度改变的偏移值，包括：通过接收基站侧发送的下行信令或者读取预配置得到接收设备进入活跃状态的时间长度改变的偏移值的取值或者取值范围。
在本实施例中，接收设备可根据接收到的偏移值延长或缩短本DRX周期的活跃时长。例如延长或缩短DrX on timer的expire时间。
在本示例中，通过接收基站等网络设备侧发送的下行信令或者读取预配置信息得到接收设备进入活跃状态的时间长度的信息，该信息包括时间长度取值或者取值范围。
示例二：
在本示例中，指示接收设备进入活跃状态时间长度的取值，包括：
通过接收基站等网络设备侧发送的下行信令或者读取预配置信息得到接收设备进入活跃状态的时间长度改变的偏移值的信息，该信息包括偏移值的取值或者取值范围。
第三种：
在本实施例中，第一指示信息，包括：接收设备DRX周期的信息。其中，该信息可以只适用于本DRX周期，或者下一个DRX周期，或者，适用于之后的一段时间内的DRX周期，或者适用于之后所有的DRX周期。当适用于之后一段时间内的DRX周期时，一段时间的长度可以通过基站配置或预配置的方法决定。
需要说明的是，在不同的应用场景中，该第一指示信息可以包含不同的内容，示例说明如下：
示例一：
在本示例中，指示信息包括指示接收设备DRX周期改变的偏移值。例如配置的偏移值为{-8，-4,-2，0,2，4,8}，通过3比特指示具体使用哪个偏移值。这里指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
示例二：
在本示例中，指示信息包括指示接收设备DRX周期的取值。比如，指示接收设备DRX周期的活跃时长和退出时长等。
其中，在一些可能的实施例中，可通过接收基站等网络设备侧发送的下行信令或者读取预配置信息得到接收设备DRX周期改变的偏移值的信息，该偏移值的信息包括偏移值的取值或者取值范围。
在另一些可能的实施例中，可以通过接收基站等网路设备侧发送的下行信令或者读取预配置信息得到接收设备DRX周期的信息，该信息包括DRX周期的取值或者取值范围。
在实际执行过程中，可以在直连控制信令中直接指示是否携带接收设备DRX周期的指示信息，也可以通过不同的直连控制信令格式隐式指示本次直连控制信令传输是否携带DRX周期值指示，比如，可通过1st stage SCI，也有可能是2nd stage SCI，也有可能是两者之和或其他SCI格式隐式指示本次直连控制信令传输是否携带DRX周期值指示，例如，在1st stage SCI或者对应的2nd stage SCI中携带1比特信息域。只有当取值“是”的时候，接收设备才根据与1st stage SCI或者本次2nd stage SCI传输对应的1st stage SCI中包含的资源预留信息进入活跃状态。这里说的与2nd stage SCI对应的1st stage SCI指的是他们对应着相同的PSSCH传输。
其中，在一些可能的实施例中，针对DRX周期的指示信息可以只适用于之后的一段时间，这一段时间的长度可以通过基站配置或预配置的方法决定。
综上，本公开实施例的直连通信的指示方法，可以根据场景灵活采用不同的方式生成接收设备进行非连续接收DRX操作的指示信息。由此，提高了直连通信指示的灵活性。
下面其次集中在接收设备侧描述本发明实施例的直连通信控制方法。
图2是根据本发明实施例提供的另一种方法的流程图，其中，包括：
步骤201，接收直连控制信令，其中，直连控制信令包括控制接收设备进行非连续接收DRX的第一指示信息。
在本实施例中，接收设备接收发送设备发送的直连控制信令，其中，直连控制信令携带控制接收设备进行非连续接收DRX的第一指示信息，该指示信息包含多种可能的格式，将会在后续实施例说明，在此不再赘述。
步骤202，根据第一指示信息进行DRX操作。
在本实施例中，接收设备直接根据第一指示信息进行DRX操作，由此，使得发送设备在预留的资源下接收设备已经进入活跃状态，平衡了系统性能和能耗。
其中，本实施例中的发送设备预留的资源预留信息可能是非周期性的资源预留字段，指示同一个传输块(TB)的后续重复传输的时间频率资源；也可能是周期性的资源预留字段，指示周期性预留的周期取值。接收设备有可能只依据周期性预留所指示的预留资源的时域位置进入活跃状态，也有可能只依据非周期性预留所指示的预留资源的时域位置进入活跃状态，也有可能两者都包括。
综上，本发明实施例的直连通信控制方法，接收设备接收发送设备发送的接收直连控制信令，其中，直连控制信令携带控制接收设备进行非连续接收DRX操作的第一指示信息，进而，接收设备根据第一指示信息进行DRX操作。由此，避免发送设备无法确保预留资源一定处于接收设备的活跃时间内，平衡了节能和系统性能。
在实际执行过程中，用户设备根据指示信息进行DRX操作的方式可以根据场景的不同而不同，理论上可以包括任意可以实现根据发送设备的预留资源调整的方式，下面结合三种可能的实现方式举例说明：
第一种：
在本示例中，根据第一指示信息进行DRX操作，包括：根据第一指示信息指示的接收设备进入活跃状态的时刻的信息进入活跃状态。
在一些可能的实施例中，若是直连控制信令为物理层直连控制信息，该物理直连控制信息中包括预留的时间频率资 源位置的第二指示信息，则可根据第二指示信息指示的为未来直连传输所预留的时间频率资源位置的指示信息进入活跃状态的时刻。由此，使得所预留的时间频率资源下，接收设备进入活跃状态，避免能耗的增加。
其中，该控制接收设备进入活跃状态的时刻的指示信息，在不同的场景中可以不同，示例如下：
示例一：
在本示例中，在预留的时间频率资源位置的指示信息指示的时间频率资源之前的T时间进入活跃状态。
其中，T时间可以通过接收基站等网络设备侧发送的下行控制信令得到，也可以通过预配置信息得到，还可以通过接收物理层直连控制信息携带的T取值的指示信息得到等。
其中，这里在T时间之前指在预留时频率资源的某个参考时间位置之前T时间。例如参考时间位置为时频率资源的起始OFDM symbol位置，或，预留时频率资源所在的slot等等；T的单位可以是物理时间单位，也可以是逻辑时间单位，例如，秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
在一些可能的实施例中，T的取值范围包括0，可以是固定值；也可能取值由设备的能力决定的；或者取值通过接收基站下行控制信令或读取预配置信息得到。
其中，也可以为T(预)配置一组值，正如以上提到的，通过物理层控制信息指示具体取哪一个值。正如以上提到的，在一些可能的中，物理层控制信息中预留的时间频率资源位置的指示信息也指示接收设备是否进入活跃状态的时刻的指示。
例如，在1st stage SCI中或对应的2nd stage SCI中携带指示T的取值的指示信息，接收设备在根据1st stage SCI中的预留时频率资源信息进入活跃状态时，使用1st stage SCI或对应2nd stage SCI中指示的T的取值。
示例二：
在本示例中，根据第一指示信息指示的所述接收设备进入活跃状态的时刻的信息进入活跃状态，包括：根据第一指示信息指示的接收设备进入活跃状态的时刻的偏移值，调整后续DRX周期进入活跃状态的时刻。例如，配置的偏移值为{-8，-4,-2，0,2，4,8}，可以通过3比特指示具体使用哪个偏移值。
在一些可能的示例中，根据接收设备进入活跃状态的时刻的偏移值的第一指示信息，调整后续DRX周期进入活跃状态的时刻，包括以下至少之一：
(1)根据指示接收设备进入活跃状态的时刻的偏移值的第一指示信息，调整下一个DRX周期进入活跃状态的时刻。比如，可以将进入下一个DRX周期进入活跃状态的时刻根据偏移值提前或者延迟等。
例如，指示的偏移值为-4slot，那么接收设备在下一个周期提前4个slot进入活跃状态；如果指示的偏移值为2slot，那么接收设备延后2个slot进入活跃状态。这里和之后指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
例如，接收设备根据当前的帧号，slot号判断下一个DRX周期启动DRX on timer的时间，当(DFN*1个Frame里的slot数目+当前slot号)％(DRX周期)＝(配置offset)％(DRX周期)时才启动DRX on timer，其中DFN为sidelink的帧号，DRX周期和配置offset为基站配置或预配置值。
(2)根据指示接收设备进入活跃状态的时刻的偏移值的第一指示信息，调整后续预设时段内DRX周期进入活跃状态的时刻。即在本实施例中，确定后续预设时间段内包括的所有的DRX周期，可以将该所有DRX周期进入活跃状态的时刻根据偏移值提前或者延迟等。在一些可能的实施例中，可以通过接收基站等网络设备侧发送的下行信令，或者，读取预配置信息得到接收设备调整后续预设时段内DRX周期进入活跃状态的时刻所对应的预设时段长度。
例如，指示的偏移值为-4slot，那么接收设备在预设时间段内所有DRX周期提前4个slot进入活跃状态；如果指示的偏移值为2slot，那么接收设备在预设时间段内所有DRX周期延后2个slot进入活跃状态。这里和之后指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
例如，接收设备根据当前的帧号，slot号判断启动预设时间段内所有DRX周期的DRX on timer的时间，当(DFN*1个Frame里的slot数目+当前slot号)％(DRX周期)＝(配置offset)％(DRX周期)时才启动DRX on timer，其中DFN为sidelink的帧号，DRX周期和配置offset为基站配置或预配置值。
(3)根据指示接收设备进入活跃状态的时刻的偏移值的第一指示信息，调整后续所有DRX周期进入活跃状态的时刻。在本实施例中，直接将所有DRX周期进入活跃状态的时刻根据偏移值提前或者延迟等。
例如，指示的偏移值为-4slot，那么接收设备在后续所有DRX周期提前4个slot进入活跃状态；如果指示的偏移值 为2slot，那么接收设备在后续所有DRX周期延后2个slot进入活跃状态。这里和之后指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
例如，接收设备根据当前的帧号，slot号判断启动后续所有DRX周期的DRX on timer的时间，当(DFN*1个Frame里的slot数目+当前slot号)％(DRX周期)＝(配置offset)％(DRX周期)时才启动DRX on timer，其中DFN为sidelink的帧号，DRX周期和配置offset为基站配置或预配置值。
在实际执行过程中，如果在一个DRX周期内接收到多个指示接收设备进入活跃状态的时刻的偏移值指示信息，使用最后接收到的一个偏移指示信息调整后续DRX周期进入活跃状态的时刻。
第二种：
在本实施例中，根据第一指示信息进行DRX操作，包括：根据第一指示信息指示的接收设备进入活跃状态的时间长度的信息控制DRX周期内的活跃时长。
在一些可能的实施例中，根据指示接收设备进入活跃状态时间长度改变的偏移值延长或缩短DRX周期内的活跃时长。
在另一些可能的实施例中，根据指示接收设备进入活跃状态时间长度的取值确定DRX周期内的活跃时长。
其中，根据指示接收设备进入活跃状态时间长度的取值确定DRX周期内的活跃时长的方式，可以为下述任意一种：
(1)可以根据指示接收设备进入活跃状态时间长度的取值确定DRX周期内的活跃时长。
在本实施例中，可以直接将指示接收设备进入活跃状态时间长度作为DRX周期内的活跃时长。
(2)可以根据指示接收设备进入活跃状态的时间长度的第一指示信息，控制下一个DRX周期内的活跃时长。
在本实施例中，在本实施例中，可以直接将指示接收设备进入活跃状态时间长度作为下一个DRX周期内的活跃时长。
(3)根据指示接收设备进入活跃状态的时间长度的第一指示信息，控制后续预设时段内DRX周期内的活跃时长。
在本实施例中，确定后续预设时段内包括的所有DRX周期，可以直接将指示接收设备进入活跃状态时间长度作为后续预设时段内包括的所有DRX周期的活跃时长。
在本公开的一个实施例中，可以通过接收基站等网络设备侧发送的下行信令，或者，读取预配置信息得到接收设备控制后续预设时段内DRX周期内的活跃时长所对应的预设时段长度。
(4)根据指示接收设备进入活跃状态的时间长度的第一指示信息，控制后续所有DRX周期内的活跃时长。
在本实施例中，确定后续所有DRX周期，可以直接将指示接收设备进入活跃状态时间长度作为后续的所有DRX周期的活跃时长。
第三种：
在本实施例中，根据第一指示信息进行DRX操作，包括：根据第一指示信息指示的接收设备DRX周期的指示信息确定DRX周期。
需要说明的是，在不同的应用场景中，该指示信息可以包含不同的内容，示例说明如下：
示例一：
在本示例中，指示信息包括指示接收设备DRX周期改变的偏移值。根据指示接收设备DRX周期改变的偏移值延长或缩短DRX周期。
例如配置的偏移值为{-8，-4,-2，0,2，4,8}，通过3比特指示具体使用哪个偏移值。这里指示的偏移值的单位可以是物理时间单元也可以是逻辑时间单元，例如秒，毫秒，帧，子帧，slot，OFDM symbol，存在合适直连时频率资源的slot等。
示例二：
在本示例中，指示信息包括指示接收设备DRX周期的取值，从而，根据指示接收设备DRX周期的取值确定DRX周期。比如，指示接收设备DRX周期的活跃时长和退出时长等。
在本实施例中，根据直连控制信令携带的接收设备DRX周期的指示信息确定DRX周期，包括下面集中几种的任一种：
(1)根据指示接收设备DRX周期的第一指示信息，确定当前DRX周期。
在本实施例中，直接根据指示接收设备DRX周期的指示信息，确定当前DRX周期，仅仅根据该指示信息调整当前的DRX周期。
(2)根据指示接收设备DRX周期的第一指示信息，确定下一个DRX周期。

在本实施例中，确定后续所有DRX周期，根据指示接收设备DRX周期的指示信息，确定后续所有DRX周期，根据该指示信息调整后续预设时段内的所有DRX周期。
综上，本公开实施例的直连通信控制方法，可以根据场景灵活采用不同的方式根据发送设备发送的非连续接收DRX操作的指示信息，进行DRX操作。由此，提高了直连通信时，DRX操作的灵活性。
