附图说明
图1是本发明实施例一种设置DRX的活动态的方法的流程图；
图2是本发明实施例一种设置DRX的活动态的装置的结构示意图。
具体实施方式
在普通的无线蜂窝通信中，由于用户设备通常使用电池，为了延长电池的使用时间，避免频繁换电池或者充电，出于节能目的，引入了DRX机制。当用户设备配置了DRX，其只在特定的条件下或特定的时间段内监听来自基站等网络设备的控制信息，例如承载在物理下行控制信道(Physical downlink control channel，PDCCH)上的下行控制信息(Downlink Control information，DCI)，这里的控制信息包括调度上下行资源的控制信息，也包括例如用于调整用户设备发送功率的控制信息。由于用户设备不需要时刻检测控制信息，因此可以降低能耗。
在边链路通信过程中也需要降低用户设备的功耗。
针对该问题，本发明实施例在边链路通信中引入了DRX机制，即，只在特定的条件下或特定的时间段内监听来自发送用户设备的控制信息，从而可以有效地降低接收用户设备的功耗。
在边链路通信的多种场景(包括CSI上报的场景和盲重传的场景)中，如在与SCI关联的传输中，可能存在用户设备处于睡眠态而无法及时收到另一个用户设备发送的信息。
针对该问题，本发明实施例设置了与SCI关联的有效时间，其开始于用户设备发出或者收到SCI的时刻、或者自发出或收到边链路控制信息后一段时间内的时刻。自该时刻起的有效时间内用户设备处于活动态，从而在与SCI关联的传输中，用户设备可以及时收到另一个用户设备发送的信息。
在CSI上报的场景中，发送用户设备获取了CSI(CSI是无线信道的信道属性，反应了信道的通信质量)后，可以调整资源分配的参数。具体而言，当发送用户设备准备向接收用户设备发送数据时，发送用户设备可以通过发送SCI要求接收用户设备反馈其收到的参考 测量信号的信息(即CSI)以确定其至接收用户设备方向的无线信道的质量；接收用户设备可以在规定的时间内反馈CSI，但如果此时发送用户设备处没有任何定时器(timer)在运行而处于睡眠态，则无法收到接收用户设备反馈的CSI。
针对CSI上报场景中的该具体问题，本发明实施例将发送用户设备设置成自其发出SCI的时刻、或者自发出SCI后一段时间内的时刻开始的有效时间内处于活动态；由于发送用户设备在该有效时间内处于活动态，因此，其能够及时(如在规定的时间内)收到接收用户设备反馈的CSI。
在盲重传的场景中，接收用户设备反馈了否定应答(NACK)信息后，会启动混合自动重传请求往返时间定时器(Hybrid Automatic Repeat reQuest Round-Trip Time，HARQ RTT timer)，HARQ RTT timer超时时，会启动重传定时器(retransmission timer)，等待发送用户设备的重传。边链路通信可以支持资源预留，例如，发送用户设备一次获得5个资源，但高层配置的最大资源个数为3，则可用的资源数为3，其中，第一个SCI指示第一个资源用于本次传输，剩余的2个资源预留，其可用于本次传输的重传，也可以用于新的传输；当本次传输的资源和后续传输的预留资源不满足HARQ RTT(不满足HARQ RTT表示，本次传输的资源与后续连续的预留资源之间的时间差较小，而不足以让发送用户设备收到接收用户设备的HARQ反馈(HARQ feedback)，并根据feedback的是接收成功还是失败来判断是否重传)时，发送用户设备发出的SCI中可以指示不需要HARQ feedback，而不需要HARQ feedback的盲重传不启动HARQ RTT timer(进而不会在HARQ RTT timer超时时启动retransmission timer)，但如果此时接收用户设备处于睡眠态，则无法收到发送用户设备在预留的后续资源上发送的SCI，如第2个SCI。
针对盲重传场景中的该具体问题，本发明实施例将接收用户设备设置成自其收到SCI开始的时刻、或者自收到SCI后一段时间内的时 刻开始的有效时间内处于活动态；由于接收用户设备自收到SCI开始的有效时间内处于活动态，因此，其能够及时收到发送用户设备在预留的后续资源上发送的SCI。
本发明实施例的技术方案可以应用于3G、4G通信系统，也可以应用于5G系统以及未来演进的共用陆地移动通信网络(Public Land Mobile Network，PLMN)等系统，其中，5G系统包括两种组网，即非独立组网(Non-Standalone，NSA)和独立组网(Standalone，SA)。
在本发明的实施例中，用户设备(User Equipment，UE)可以为接入终端、用户单元、用户站、移动站、移动台(Mobile Station，建成MS)、远方站、远程终端、移动设备、用户终端、终端设备(Terminal Equipment)、无线通信设备、用户代理或用户装置；用户设备还可以为蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称SIP)电话、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字处理(Personal Digital Assistant，简称PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的用户设备或者未来演进的PLMN中的用户设备等，本申请实施例对此并不限定。
在本发明的实施例中，用户设备可以包括边链路通信中的发送用户设备和接收用户设备。在边链路通信的交互过程中，用户设备可以既为发送用户设备、又为接收用户设备；但是，在一次具体的传输中，可以将发送SCI的设备称为发送用户设备、接收SCI的设备称为接收用户设备。
在本发明的实施例中，“第一”和“第二”等描述，仅作示意与区分描述对象之用，没有次序之分，也不表示本发明实施例中对设备个数的特别限定，不构成对本发明实施例的任何限制。
本发明的实施例中，“时隙”是对将时间分割成周期性的时间段后对这些时间段的统称，它可以是时隙(time slot)，帧(frame)，子帧(subframe)等，本申请实施例对此并不限定。
为了使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种设置DRX的活动态的方法100的流程图，包括以下步骤：
步骤S110：将用户设备设置成在有效时间内处于活动态，有效时间的开始时刻为用户设备发出或收到边链路控制信息的时刻、或者自发出或收到边链路控制信息后一段时间内的时刻。
用户设备包括第一用户设备和第二用户设备。
SCI与用户设备的传输数据关联，传输数据可以是CSI，也可以是应用层数据。
边链路通信会涉及与SCI关联的传输，其中可能存在用户设备处于睡眠态而无法及时收到另一个用户设备发送的信息。
针对该问题，于步骤S110中设置了与SCI关联的有效时间，其开始于用户设备发出或收到SCI的时刻、或者自发出或收到SCI后一段时间内的时刻。自该时刻起的有效时间内用户设备处于活动态，从而在与SCI关联的传输中，用户设备可以及时收到另一个用户设备发送的信息。
该一段时间在大于0至小于20毫秒的范围内。
有效时间可以在1至20毫秒(ms)的范围内。
步骤S110的一些具体实施例适于CSI上报的场景。
在CSI上报的场景中，第一用户设备向第二用户设备发出触发CSI的SCI后，第二用户设备向第一用户设备发送CSI(其中包含CSI报告)以及调度该CSI的SCI。
在CSI上报的场景中，有效时间具有开始时刻和结束时刻，在该有效时间内，第一用户设备处于活动态。开始时刻可以为第一用户设备向第二用户设备发出SCI的时刻。开始时刻也可以为第一用户设备 向第二用户设备发出SCI之后一段时间内的某一时刻，该一段时间在大于0至小于20毫秒的范围内；例如，开始时刻可以为发出SCI之后的3ms，具体的数值可以由基站设置或由协议规定。
结束时刻可以为第一用户设备未收到CSI的规定时间。规定时间可以由与第一用户设备建立连接的基站设备设置，也可以由第一用户设备预先配置。规定时间可以在3至20ms的范围内。
具体而言，第一用户设备可以根据其收到的、由第二用户设备发出的CSI与SCI的映射关系而确定未收到CSI。该映射关系反映了CSI与请求该CSI的SCI的对应关系。
例如，第一用户设备可能发送了两个SCI用于请求CSI反馈，当其收到一个CSI反馈时，根据映射关系，如果确定该CSI对应第二个SCI，也就是该CSI不对应第一个SCI，则对于第一个SCI而言，其所对应的有效时间仍然为自第一用户设备发出第一个SCI的时刻(即开始时刻)至规定时间，也就是认为第一个SCI对应的CSI未收到。
又例如，第一用户设备可能发送了两个SCI用于请求CSI反馈，当其收到一个CSI反馈时，根据映射关系，如果无法确定该CSI对应哪一个SCI，则对于两个SCI而言，其各自所对应的有效时间仍然为自第一用户设备发出SCI的时刻(即开始时刻)至规定时间，也就是认为两个SCI对应的CSI均未收到。
结束时刻也可以为第一用户设备收到第二用户设备发出的CSI的时刻。其中，第一用户设备收到第二用户设备发出的CSI可以基于CSI与SCI的映射关系而确定，也可以基于第一用户设备收到第二用户设备发出的CSI的报告而确定。
具体而言，第一用户设备可以根据其收到的、由第二用户设备发出的CSI与SCI的映射关系而确定收到了该CSI。该映射关系反映了CSI与请求该CSI的SCI的对应关系。
例如，第一用户设备可能发送了两个SCI用于请求CSI反馈，当 其收到一个CSI反馈时，根据映射关系，如果确定该CSI对应第一个SCI，则可以将第一用户设备发出第一个SCI的时刻(即开始时刻)至其收到该CSI的时刻(结束时刻)的时间确定为第一个SCI的有效时间(如称为第一有效时间)，第一用户设备在该第一有效时间内处于活动态；在该第一有效时间结束后，第一个SCI对应的活动态可以取消。类似地，独立于第一有效时间的确定，第二个SCI对应的有效时间(如称为第二有效时间)可以为自第一用户设备发出第二个SCI的时刻(即开始时刻)至其收到与该第二个SCI映射或对应的CSI的时刻(结束时刻)的时间确定为第二个SCI的第二有效时间，第一用户设备在该第二有效时间内处于活动态。
具体而言，第一用户设备还可以根据其收到的、由第二用户设备发出的CSI报告确定收到了该CSI。
例如，第一用户设备可以基于指示信息确定收到了第二用户设备发出的CSI报告。在具体实施中，第一用户设备向第二用户设备发出触发CSI的SCI后，第二用户设备向第一用户设备发送CSI(其中包含CSI报告)以及调度该CSI的SCI，第一用户设备可以从调度该CSI的SCI的指示信息中推断出收到了第二用户设备发出的CSI报告。
又例如，第一用户设备也可以从CSI中解码出具体的CSI报告而确定收到了第二用户设备发出的CSI报告。在具体实施中，第一用户设备向第二用户设备发出触发CSI的SCI后，第二用户设备向第一用户设备发送CSI(其中包含CSI报告)以及调度该CSI的SCI，第一用户设备可以从该CSI中解码出具体的CSI报告而确定收到了第二用户设备发出的CSI报告。
步骤S110的另一些具体实施例适于盲重传场景。
在盲重传的场景中，当第一用户设备判断出本次传输的资源和后续传输的资源不满足HARQ RTT时，第一用户设备可以发出SCI，其中指示第二用户设备不发送HARQ feedback，相应地，第一用户设 备也不基于HARQ feedback而发出SCI(即盲重传)。可选地，第一用户设备发出的SCI为指示重传的SCI。
在盲重传的场景中，有效时间具有开始时刻和结束时刻，在该有效时间内，第二用户设备处于活动态。开始时刻可以为第二用户设备收到由第一用户设备发出的SCI的时刻或者其后一段时间内的时刻，该一段时间在大于0至小于20毫秒的范围内。
结束时刻可以为HARQ RTT确定的时刻，其中，HARQ RTT表示重传若是基于HARQ feedback所需要的与初始传输相距的最小时间长度。由于不满足HARQ RTT，导致第二用户设备不发送HARQ feedback(如不发送NACK)，第一用户设备也不基于HARQ feedback而直接进行重传；在第一用户设备发出一个指示不需要HARQ feedback的SCI时，在之后的HARQ RTT时间内，可能还存在SCI，因此，可以将结束时刻设置为HARQ RTT确定的时刻(即经过HARQ RTT所确定的时间而到达的时刻)。
结束时刻也可以为重传定时器确定的结束时刻。具体而言，在接收用户设备收到SCI的时刻，启动重传定时器，在重传定时器确定的时间内，处于活动态，在重传定时器运行的结束时刻，用户设备结束活动态而开始进入睡眠态。
结束时刻也可以为SCI指示的预留资源所在时隙的结束时刻所对应的时刻。例如，发送用户设备可用的资源数为N(N为大于1的整数)，发送用户设备在发出第一个SCI后，该第一个SCI还指示了后续N-1个预留资源所在时隙的结束时刻对应的时刻，可以将这N-1个预留资源所在时隙的结束时刻对应的时刻分别设置为结束时刻；可以将第二用户设备收到由第一用户设备发出的第一个SCI的时刻记为开始时刻，N-1个预留资源所在时隙的结束时刻分别对应N-1个结束时刻；开始时刻分别结合N-1个结束时刻从而可以得到N-1个有效时间。
在一个实施例中，有效时间的开始时刻和结束时刻都可以为SCI 指示的预留资源所对应的时刻。例如，发送用户设备具有若干个可用的资源数，开始时刻可以为在先预留资源所在时隙的开始时刻所对应的时刻，结束时刻可以为在后预留资源所在时隙的结束时刻所对应的时刻。又例如，发送用户设备具有至少一个可用资源数，开始时刻可以为任一预留资源所在时隙的开始时刻所对应的时刻，结束时刻可以为该任一预留资源所在时隙的结束时刻所对应的时刻。
本发明实施例公开了一种存储介质，其上存储有计算机指令，该计算机指令运行时执行以上结合图1所述方法的步骤。
