- the idle (RRC IDLE) state can save the power consumption of the terminal. For example, some non-real-time applications (web browsing, instant communication, etc.) always exist for a period of time, and the terminal does not need to continuously monitor downlink data, and does not need to perform correlation. Processing, DRX can be applied to such a scenario.
- the terminal since there is an RRC connection in the Active DRX state, the terminal has to go to the state of listening to the downlink data very quickly.

- the terminal maintains a waking time each time it wakes up from DRX, and the terminal searches during that time. PDCCH.
- stop timer Inactivity Timer
- the terminal When the terminal is awake, it successfully keeps the active time after the PDCCH originally transmitted by the HARQ (Hybrid Automatic Repeat Reqest) is successfully decoded, that is, when the PDCCH received by the terminal indicates an initial transmission of UL/DL.

At this time, the ON Duration Timer and the DRX Inactivity Timer are stopped, but the timer related to the retransmission is not stopped, and the terminal is required to continue. Listen for retransmitted content.
- the starting point for setting up the two-stage DRX Cycle is that it is more likely that there will be data transmission immediately after the end of a data transmission process of the terminal. Therefore, a short DRX Cycle is set to cope with this probability, and there is no data in several short DRX cycles. To transmit, it means that the data transmission has indeed been completed, and it can enter deep sleep state, so that long and short period cooperation can achieve better DRX. effect.

Description
一种非连续接收方法及*** 技术领域 Discontinuous receiving method and system
本发明涉及移动通信领域, 尤其涉及一种非连续接收方法及***。 背景技术 The present invention relates to the field of mobile communications, and in particular, to a discontinuous reception method and system. Background technique
非连续接收(DRX, Discontinuous Reception )指的是终端在一段时间 里停止监听物理下行控制信道 ( PDCCH , Physical Downlink Control Channel )。 DRX分两种: 一种是空闲( IDLE ) DRX, 就是当终端处于 IDLE 状态下的非连续接收; 处于 IDLE 状态时, 已经没有无线资源控制协议 ( RRC , Radio Resource Control )连接和用户的专有资源, 因此 IDLE DRX 主要用于监听呼叫信道与广播信道, 只要定义好固定的周期, 就可以达到 非连续接收的目的; 但是, 如果终端监听用户数据信道, 则必须从 IDLE状 态先进入连接状态。 另一种就是激活 (Active ) DRX, 就是终端处在 RRC 连接(RRC-CONNECTED )状态下的 DRX, 可以优化***资源配置, 更重 要的是可以节省终端功耗, 不需要通过让终端进入到 RRC 空闲 ( RRC IDLE )状态就可以达到节省终端功耗的目的, 例如一些非实时应用 ( web 浏览、 即时通信等) 总是存在一段时间, 终端不需要不停的监听下 行数据, 也不需要进行相关处理, DRX就可以应用到这样的场景中。 此外, 由于 Active DRX状态下存在 RRC连接, 因此终端要转到监听下行数据的 状态的速度非常快。 Discontinuous Reception (DRX) means that the terminal stops listening to the Physical Downlink Control Channel (PDCCH) for a period of time. There are two types of DRX: one is idle (IDLE) DRX, which is the discontinuous reception when the terminal is in the IDLE state; when in the IDLE state, there is no RRC (Radio Resource Control) connection and the user's proprietary Resources, therefore IDLE DRX is mainly used to monitor the call channel and the broadcast channel. As long as a fixed period is defined, the discontinuous reception can be achieved. However, if the terminal listens to the user data channel, it must first enter the connection state from the IDLE state. The other is to activate (Active) DRX, which is the DRX in the RRC-CONNECTED state of the terminal. It can optimize system resource configuration. More importantly, it can save terminal power consumption. It does not need to let the terminal enter RRC. The idle (RRC IDLE) state can save the power consumption of the terminal. For example, some non-real-time applications (web browsing, instant communication, etc.) always exist for a period of time, and the terminal does not need to continuously monitor downlink data, and does not need to perform correlation. Processing, DRX can be applied to such a scenario. In addition, since there is an RRC connection in the Active DRX state, the terminal has to go to the state of listening to the downlink data very quickly.
DRX中存在一些定时器, 下面描述一些定时器, 其中所有的时间都是 基于子帧的, 即以 ms为单位): There are some timers in DRX. Some timers are described below, where all times are subframe-based, that is, in ms:
1、 持续工作定时器( On Duration Timer ) 1, On Duration Timer
终端每次从 DRX 醒来后维持醒着的时间, 终端在该段时间内会搜索
PDCCH。 The terminal maintains a waking time each time it wakes up from DRX, and the terminal searches during that time. PDCCH.
2、 停止定时器( Inactivity Timer ) 2, stop timer (Inactivity Timer)

After (instead of retransmission), it is necessary to maintain Active time. When the terminal is awake, it will keep Active for each time it successfully decodes the PDCCH originally transmitted by HARQ.
3、 一次醒来后总的工作定时器 ( Active Timer ) 3. The total working timer (Active Timer) after waking up
终端从 DRX醒来后保持醒着的总时间,在此时间段,终端监听 PDCCH, 包括所有导致终端处于 Active的状态 ,比如是 DRX周期开始 "On Duration" , 或收到初始传输的 PDCCH, 或监听重传等。 The total time that the terminal stays awake after waking up from the DRX. During this time period, the terminal monitors the PDCCH, including all the states that cause the terminal to be Active, such as the DROn cycle starting "On Duration", or receiving the PDCCH of the initial transmission, or Listen for retransmissions, etc.
如果配置了 DRX,那么 Active Time 包括以下时间: On Duration Timer、 Inactivity Timer、 DRX重传定时器( DRX Retransmission Timer )以及 MAC 层拥塞解决定时器( MAC Contention Resolution Timer )运行的时间; 或, 有调度请求(SR, Scheduling Req终端 set ) 已经发送到 PUCCH, 并且处于 挂起的状态(也就是这个调度请求还没有满足); 或, 对一个挂起的 HARQ 存在上行授权, 并且在对应的 HARQ 緩冲区里有数据; 或, 在非竟争随机 接入后,成功收到随机接入响应消息,此时应有 PDCCH发送给终端指示一 个新的传输,但是这个 PDCCH还没有收到, 此时终端还是必须处于 Active 状态。 If DRX is configured, the Active Time includes the following times: On Duration Timer, Inactivity Timer, DRX Retransmission Timer, and MAC Layerion Resolution Timer running time; or, there is scheduling The request (SR, Scheduling Req terminal set) has been sent to the PUCCH and is in a suspended state (that is, the scheduling request has not been met); or, there is an uplink grant for a pending HARQ, and the corresponding HARQ buffer There is data in the area; or, after the non-contention random access, the random access response message is successfully received. At this time, the PDCCH should be sent to the terminal to indicate a new transmission, but the PDCCH has not been received yet. Still have to be in the Active state.
4、 HARQ往返定时器( HARQ RTT Timer ) 4. HARQ Round Trip Timer ( HARQ RTT Timer )
终端预期下行重传( DL Retransmission )到达的最少间隔时间, 就是终 端暂且不需要理会重传最早会什么时候到, 只要这个定时器超时, 终端就 要处于醒着的状态。 The minimum interval at which the terminal expects the downlink retransmission (DL Retransmission) to arrive is that the terminal does not need to pay attention to when the retransmission will occur at the earliest. As long as the timer expires, the terminal is in a awake state.
5、 DRX Retransmission Timer
终端预期接收 DL Retransmission的时间, 就是需要这么多时间来接受 下行 5, DRX Retransmission Timer The time that the terminal expects to receive the DL Retransmission is that it takes so much time to accept the downlink.
6、 DRX周期长度( DRX Cycle length ) 6, DRX cycle length (DRX Cycle length)
DRX Cycle length一旦配置 /重配置就固定不变, 不会因为 Active Time 大于 On Duration而发生变 4匕。 Once the DRX Cycle length is configured/reconfigured, it will not change because Active Time is greater than On Duration.
现有的 DRX的运行过程主要包括: 如果使用短 DRX Cycle , 则检查当 前子帧是否满足公式: [(SFN * 10) + subframe number] modulo (shortDRX-Cycle) = (drxStartOffset) modulo (shortDRX-Cycle); 如果使用长 DRX周期, 则检查当前子帧是否满足公式: [(SFN * 10) + subframe number] modulo (longDRX-Cycle) = drxStartOffset;当上面的两个条件满足其中之一, 那么就启动 On Duration Timer, 此时终端开始监听 PDCCH。 当这个子帧 HARQ RTT Timer (期望重发的最短时间)超时, 重发就有可能到来, 如果 这时对于 HARQ进程的软緩冲区还有没有解码成功的数据(也就是前面的 数据接收失败了, 需要数据重传), 就启动 DRX Retransmission Timer开始 监听 PDCCH重传相关的数据。 如果收到 DRX MAC控制信息单元, 就意 味着 eNB要求终端进入睡眠状态,这时就会停止 ON Duration Timer和 DRX Inactivity Timer, 但是并不会停止跟重传相关的定时器, 用于要求终端继续 监听重传的内容。当 DRX Inactivity Timer超时或收到 DRX MAC控制信息 单元时, 如果配置了短 DRX Cycle, 那么启动或重启短 DRX周期定时器 ( Short DRX Cycle Timer ), 使用短 DRX Cycle; 否则, 使用长 DRX Cycle; 如果 Short DRX Cycle Timer超时, 那么使用长 DRX Cycle。 The existing DRX operation process mainly includes: If the short DRX Cycle is used, it checks whether the current subframe satisfies the formula: [(SFN * 10) + subframe number] modulo (shortDRX-Cycle) = (drxStartOffset) modulo (shortDRX-Cycle If a long DRX cycle is used, check if the current subframe satisfies the formula: [(SFN * 10) + subframe number] modulo (longDRX-Cycle) = drxStartOffset; when the above two conditions satisfy one of them, then start On Duration Timer, the terminal starts to monitor the PDCCH. When this subframe HARQ RTT Timer (the shortest time expected to be retransmitted) times out, retransmission may come, if there is still no successful decoding data for the soft buffer of the HARQ process (that is, the previous data reception failure After the data retransmission is required, the DRX Retransmission Timer is started to start monitoring the data related to the PDCCH retransmission. If the DRX MAC control information element is received, it means that the eNB requires the terminal to enter a sleep state. At this time, the ON Duration Timer and the DRX Inactivity Timer are stopped, but the timer related to the retransmission is not stopped, and the terminal is required to continue. Listen for retransmitted content. When the DRX Inactivity Timer expires or receives the DRX MAC control information element, if a short DRX Cycle is configured, start or restart the short DRX Cycle Timer, use the short DRX Cycle; otherwise, use the long DRX Cycle; If the Short DRX Cycle Timer times out, then use a long DRX Cycle.
设置两级 DRX Cycle的出发点是认为终端的一次数据传输过程结束后 马上再有数据传输的可能性较大, 因此设置一个短 DRX Cycle来应对这种 概率, 当几个短 DRX Cycle内一直没有数据要传输, 说明该次数据传输确 实已经完成,可以进入深睡眠状态,这样长短周期配合能够达到更好的 DRX
效果。 The starting point for setting up the two-stage DRX Cycle is that it is more likely that there will be data transmission immediately after the end of a data transmission process of the terminal. Therefore, a short DRX Cycle is set to cope with this probability, and there is no data in several short DRX cycles. To transmit, it means that the data transmission has indeed been completed, and it can enter deep sleep state, so that long and short period cooperation can achieve better DRX. effect.
上述是以 LTE***为例说明的 DRX机制中不同 Timer的定义和 DRX 执行流程。 DRX机制也可以应用在其他***,如通用移动通信***(UMTS, Universal Mobile Telecommunications System )、 全球移动通讯*** ( GSM, Global System of Mobile communication )等, 具体的执行细节略有差异, 大 体流程相似。 The above is the definition of different Timers and the DRX execution flow in the DRX mechanism described by the LTE system. The DRX mechanism can also be applied to other systems, such as Universal Mobile Telecommunications System (UMTS), Global System of Mobile Communication (GSM), etc. The specific implementation details are slightly different, and the general process is similar.
随着智能终端业务应用的丰富, 出现了很多新的数据业务传输规律。 例如及时通信类业务, 有不同周期的数据传输要求, 如终端向服务器发送 周期保活数据包(keepalive packet ), 周期性好友状态更新 (上线 /下线等) 等。尽量使得网络或终端选择的 DRX参数能适配数据发送周期是需要进一 步研究的内容; 同时, 耗电是智能终端的一个大问题, 只有在网络与终端 间的处理适配数据发送周期时才能起到最好的节电性能。 With the rich application of smart terminal services, many new data traffic transmission rules have emerged. For example, the timely communication service has different data transmission requirements, such as the terminal sending a keepalive packet to the server, a periodic friend status update (online/downline, etc.). Trying to make the DRX parameters selected by the network or terminal adapt to the data transmission period is a matter for further research. At the same time, power consumption is a big problem for intelligent terminals, and only when the processing between the network and the terminal adapts the data transmission period. To the best power saving performance.
在考虑业务特性更加复杂的情况下, 为了达到省电的目的, 需要引入 更大的 DRX Cycle, 但是如果长 DRX周期 ( long DRX Cycle )设置的很大 (如几十秒 ),而且还使用现有的两级周期控制方案,可能在几个 Short DRX Cycle 没数据需要传输, 终端将进入长 DRX Cycle, 随后终端处于长期的 sleep状态, 当在该 sleep状态时, 如果数据到达, 该数据将被緩存, 等到 On Duration期间才能传输, 必将带来较大时延。 发明内容 In the case of more complicated business characteristics, in order to achieve power saving, it is necessary to introduce a larger DRX Cycle, but if the long DRX cycle is set large (such as several tens of seconds), There are two-stage periodic control schemes. It may be that there is no data to be transmitted in several Short DRX cycles, the terminal will enter the long DRX Cycle, and then the terminal is in the long-term sleep state. When in the sleep state, if the data arrives, the data will be Cache, which can only be transmitted during the On Duration, will inevitably lead to large delays. Summary of the invention

本发明的基本思想是: 终端接收网络侧配置并发送的 DRX参数, 其中 携带多个 DRX Cycle; 终端根据所述 DRX参数启动 DRX进程 , 并在运行 DRX进程时, 启用相应的 DRX Cycle。 The basic idea of the present invention is: The terminal receives the DRX parameter configured and sent by the network side, and carries multiple DRX cycles; the terminal starts the DRX process according to the DRX parameter, and enables the corresponding DRX Cycle when the DRX process is running.
下面通过附图及具体实施例对本发明再做进一步的详细说明。 The invention will be further described in detail below with reference to the drawings and specific embodiments.
本发明提供一种非连续接收方法, 图 1 是本发明实现非连续接收方法 的流程示意图, 如图 1所示, 该方法包括以下步骤: The present invention provides a discontinuous reception method. FIG. 1 is a schematic flowchart of a method for implementing a discontinuous reception according to the present invention. As shown in FIG. 1, the method includes the following steps:
步骤 101 , 网络侧为终端配置 DRX参数, 其中携带多个 DRX Cycle, 并将配置的 DRX参数发送给终端; Step 101: The network side configures a DRX parameter for the terminal, where the DRX parameter is carried, and the configured DRX parameter is sent to the terminal.
具体的, 网络侧根据业务的特性判断业务是否适合配置 DRX机制, 例 如在一段时间内,业务数据的发送是周期性的,那么这类业务适合配置 DRX 机制, 如果业务数据的发送没有明显的规律, 则这类业务不适合配置 DRX 机制; 当网络侧确定业务适合配置 DRX机制时, 网络侧还需要判断是否需 要配置多个 DRX周期(DRX Cycle ), 例如, 如果业务数据的发送的周期性 是分时段的, 即在一段时间内业务数据的发送是周期 1 , 一段时间内业务数 据的发送是周期 2, 以此类推, 则需要配置多个 DRX Cycle; Specifically, the network side determines whether the service is suitable for configuring the DRX mechanism according to the characteristics of the service. For example, the service data is periodically sent within a period of time, and the service is suitable for configuring the DRX mechanism. If the service data is sent without obvious rules. The service is not suitable for configuring the DRX mechanism. When the network side determines that the service is suitable for configuring the DRX mechanism, the network side also needs to determine whether multiple DRX cycles need to be configured. For example, if the periodicity of service data transmission is For a period of time, that is, the transmission of service data is period 1 for a period of time, the transmission of service data for a period of time is period 2, and so on, and multiple DRX cycles need to be configured;
当需要配置多个 DRX Cycle时, 网络侧根据终端运行的业务的特性, 为终端配置 DRX参数, 该 DRX参数中携带多个 DRX Cycle, 可选的, 还 可以携带该多个 DRX Cycle 的使用策略, 另外, 还可以包括 on Duration Timer ¾ DRX Inactivity Timer、 DRX Retransmission Timer; 这里, 网络则 可以将配置的 DRX参数通过信令发送给终端, 承载 DRX参数的信令可以 是 RRC连接建立命令、 RRC连接重建命令、 RRC连接重配置命令、 切换 命令等, 也可以通过 MAC控制单元 ( MAC CE, MAC Control Element )来 配置, 或通过物理层的下行控制信息(DCI, Downlink Control Information ) 配置; 其中, 业务的特性包括构成该业务的不同用途的数据的周期性、 时
延要求等。 When multiple DRX cycles need to be configured, the network side configures DRX parameters for the terminal according to the characteristics of services running on the terminal. The DRX parameters carry multiple DRX cycles. Optionally, the DRX Cycle can also be used. In addition, the ON Duration Timer 3⁄4 DRX Inactivity Timer and the DRX Retransmission Timer may be included. Here, the network may send the configured DRX parameters to the terminal by signaling, and the signaling carrying the DRX parameters may be an RRC connection setup command, an RRC connection. The reconfiguration command, the RRC connection reconfiguration command, the handover command, and the like may also be configured by a MAC Control Element (MAC Control Element) or by a downlink control information (DCI, Downlink Control Information) of the physical layer; Characteristics include the periodicity of the data that constitutes the different uses of the service, Extension requirements, etc.
步骤 102, 终端接收网络侧配置并发送的 DRX参数, 根据该 DRX参 数启动 DRX进程, 并在运行 DRX进程时, 启用相应的 DRX Cycle; Step 102: The terminal receives the DRX parameter configured and sent by the network, starts the DRX process according to the DRX parameter, and enables the corresponding DRX Cycle when the DRX process is run.
具体的, 终端接收网络侧配置并通过信令发送的 DRX 参数, 根据该 DRX参数在终端内部启动 DRX进程; 在运行 DRX进程时 , 终端可以根据 网络侧指示和 /或预设规则和 /或自主选择, 启用相应的 DRX Cycle; Specifically, the terminal receives the DRX parameter configured by the network side and sends the DRX parameter, and starts the DRX process in the terminal according to the DRX parameter. When the DRX process is run, the terminal may perform the DRX process according to the network side indication and/or preset rules and/or autonomous. Select to enable the corresponding DRX Cycle;
如果在运行 DRX进程时, 网络侧通过 RRC信令、 MAC CE、 物理层 指示等方式指示终端, 通知终端需要启用的 DRX Cycle周, 则终端需要根 据网络侧的指示启用 DRX Cycle; If the network side is instructed by the RRC signaling, the MAC CE, the physical layer indication, etc., to notify the terminal that the DRX Cycle is to be enabled, the terminal needs to enable the DRX Cycle according to the indication on the network side.
和 /或, 如果网络侧为终端配置的 DRX参数中携带 DRX Cycle的使用 策略, 则该 DRX Cycle的使用策略作为预设规则, 终端可以根据该预设规 则, 选择启用的 DRX Cycle, 例如, 预设规则是多个 DRX Cycle的使用是 从短到长依次转换, 数据传输结束后, 终端首先启用最短的 DRX Cycle, 当规定次数的周期循环结束后(期间没有数据收发动作发生), 启用次长的 DRX Cycle, 当规定次数的周期循环结束后(期间没有数据收发动作发生 ), 再启用更长的 DRX Cycle,以此类推,在此过程中 ,如果任何一个 DRX Cycle 内, 发生数据收发动作, 则待数据收发结束后, 再重新进入上述过程; 和 /或, 终端还可以自主选择使用的 DRX Cycle, 该自主选择的方式具 体为: 终端根据业务的特性决定使用的 DRX Cycle, 并将该决定通过 RRC 信令或 MAC CE或物理层指示等方式通知网络侧; 网络侧收到通知后, 可 以通过信令回复确认信息给终端,信令可以是 RRC信令,也可以通过 MAC CE或物理层指示等将确认信息回复给终端。 And/or, if the DRX parameter configured for the terminal on the network side carries the DRX Cycle usage policy, the DRX Cycle usage policy is used as a preset rule, and the terminal may select the enabled DRX Cycle according to the preset rule, for example, The rule is that the use of multiple DRX cycles is to change from short to long. After the data transmission is finished, the terminal first enables the shortest DRX Cycle. After the specified number of cycles is over (no data transmission and reception occurs during the period), the second length is enabled. DRX Cycle, when the specified number of cycle cycles is over (no data transmission and reception occurs during the period), then the longer DRX Cycle is enabled, and so on. In this process, if any DRX Cycle occurs, data transmission and reception will occur. Then, after the data is sent and received, the process is re-entered; and/or the terminal can also independently select the DRX Cycle to be used. The method of self-selection is specifically as follows: The terminal determines the DRX Cycle to be used according to the characteristics of the service, and determines the decision. Notifying the network side through RRC signaling or MAC CE or physical layer indication; the network side receives the notification Then, the acknowledgement information may be sent back to the terminal by signaling, and the signaling may be RRC signaling, or the acknowledgement information may be returned to the terminal by using a MAC CE or a physical layer indication.
实施例一 Embodiment 1
图 2是本发明实现非连续接收方法的实施例一的 DRX Cycle的示意图, 如图 2所示, 本实施例中, 存在三个 DRX Cycle, 终端根据预设规则启用
DRX Cycle , 该实施例包括以下步骤: 2 is a schematic diagram of the DRX Cycle of the first embodiment of the method for implementing the discontinuous reception method. As shown in FIG. 2, in this embodiment, there are three DRX cycles, and the terminal is enabled according to a preset rule. DRX Cycle, this embodiment includes the following steps:
步骤 1 ,终端正在运行一个数据业务,该业务的数据发送周期比较复杂, 因此网络侧为终端配置 DRX参数, 其中包括三个 DRX Cycle, 即短 DRX 周期( short DRX Cycle )、 长 DRX周期( long DRX Cycle )、 超长 DRX周期 ( Superlong DRX Cycle ), 其中 DRX Cycle的取值可以为无限大; 同时, 网 络侧还配置了三个 DRX Cycle的使用策略即 M/N, 其中 M、 N均为大于等 于 0的整形数值, 当 M个 short DRX Cycle内没有数据发送 /接收时, 进入 long DRX Cycle; 当 N个 long DRX Cycle内没有数据发送 /接收时, 进入 Superlong DRX Cycle。 Step 1: The terminal is running a data service, and the data transmission period of the service is complicated. Therefore, the network side configures the DRX parameter for the terminal, including three DRX cycles, that is, a short DRX cycle (long DRX cycle) and a long DRX cycle (long DRX Cycle ), Super Long DRX Cycle, where the value of DRX Cycle can be infinite; at the same time, the network side is also configured with three DRX Cycle usage strategies, namely M/N, where M and N are The integer value greater than or equal to 0 enters the long DRX Cycle when there is no data transmission/reception in the M short DRX cycles. When there is no data transmission/reception in the N long DRX cycles, the Superlong DRX Cycle is entered.
步骤 2, 网络侧通过专用信令将配置的 DRX参数发送给终端。 Step 2: The network side sends the configured DRX parameters to the terminal through dedicated signaling.
步骤 3 , 终端接收到网络侧发送的专用信令后, 根据其中的 DRX参数 在终端内部启动 DRX进程。 Step 3: After receiving the dedicated signaling sent by the network side, the terminal starts the DRX process in the terminal according to the DRX parameter.
步骤 4, 终端在运行 DRX进程时, 根据 M/N来启用三个 DRX Cycle, 即首先启用 short DRX Cycle, 当 M个 short DRX Cycle内没有数据发送 /接 收时, 启用 long DRX Cycle; 当 N个 long DRX Cycle内没有数据发送 /接收 时, 再启用 Superlong DRX Cycle。 Step 4: When the terminal runs the DRX process, three DRX cycles are enabled according to the M/N, that is, the short DRX Cycle is enabled first, and when there is no data transmission/reception in the M short DRX cycles, the long DRX Cycle is enabled; When there is no data transmission/reception in the long DRX Cycle, enable Superlong DRX Cycle.
例如,当 M=2, N=2时, DRX Cycle 1对应 short DRX Cycle, DRX Cycle2 周期对应 long DRX Cycle, DRX Cycle3对应 Superlong DRX Cycle;如果 M 的值是 0,则表示终端不需要启用 short DRX Cycle,—开始就直接启用 long DRX Cycle; 同理,如果 N的值为 0,则表示终端可以跳过 long DRX Cycle, 直接启用 Superlong DRX Cycle。 For example, when M=2, N=2, DRX Cycle 1 corresponds to short DRX Cycle, DRX Cycle2 corresponds to long DRX Cycle, DRX Cycle3 corresponds to Superlong DRX Cycle; if M value is 0, it means that terminal does not need to enable short DRX Cycle, - directly enable long DRX Cycle; Similarly, if the value of N is 0, it means that the terminal can skip the long DRX Cycle and directly enable the Superlong DRX Cycle.

The signaling used to indicate the terminal may be in the form of RRC signaling and MAC control information unit. The signaling, physical layer signaling, and the signaling used to indicate the terminal may indicate the DRX Cycle that the terminal needs to enable by means of a number indication (index), without configuring the actual period value.
步骤 6, 终端根据收到的网络侧的指示, 选择启用的 DRX Cycle, 并按 该 DRX Cycle进行 DRX控制; 例如, 如图 3所示, 终端在收到网络侧的指 示后, 启用 DRX Cycle2。 Step 6. The terminal selects the enabled DRX Cycle according to the received network side indication, and performs DRX control according to the DRX Cycle. For example, as shown in FIG. 3, after receiving the indication on the network side, the terminal enables DRX Cycle2.
