Abstract

Disclosed in embodiments of the present disclosure are an energy-saving method and apparatus for a terminal device, applied to a communication system. The method comprises: a terminal device being configured to be in a C-DRX mode; the terminal device starting a retransmission timer for an HARQ process, and monitoring a low-power wake-up signal (LP-WUS); the terminal device being in an energy-saving state; if the LP-WUS is monitored before the retransmission timer times out, entering a PDCCH monitoring state from the energy-saving state; if the LP-WUS is not monitored before the retransmission timer times out, maintaining an LP-WUS monitoring state and the energy-saving state. According to the present disclosure, unnecessary PDCCH blind detection can be reduced in an energy-saving state, thereby reducing the energy consumption of a terminal. Moreover, LP-WUS monitoring is used, and when an LP-WUS is monitored, the terminal device is waked up immediately and reenters the PDCCH monitoring state, such that the effect on the delay of data transmission is small, thereby ensuring the transmission delay performance of retransmitted data.

为了便于理解,首先介绍本申请涉及的术语。To facilitate understanding, the terminology involved in this application is first introduced.
非连续接收(Discontinuous Reception,DRX)基于包的数据流通常是突发性的,在一段时间内有数据传输,但在接下来的一段较长时间内没有数据传输。在没有数据传输的时候,可以通过停止接收PDCCH(此时会停止PDCCH盲检)来降低功耗,从而提升电池使用时间。Discontinuous Reception (DRX) packet-based data flow is usually bursty, with data transmission for a period of time, but no data transmission for a long period of time. When there is no data transmission, you can reduce power consumption by stopping receiving PDCCH (at this time, PDCCH blind detection will be stopped), thereby increasing battery life.
混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)是自动重传(Automatic Repeat Request,ARQ)和前向纠错编码(Forward Error Correction,FEC)联合使用的一种差错控制技术。其目的是通过重传功能和时间分集产生的增益,保证数据包的正确传输,提高无线通信系统的可靠性。在使用HARQ之后,发送端需要向接收端反馈一个确认信息来指示发送的数据包是否被接收方正确的接收。如果确认信息为肯定应答ACK(上行指示为CRC(循环冗余码校验,Cyclic Redundancy Check)OK,以下统称为ACK),表示数据包已经被接收方正确接收;如果确认消息为否定应答NACK(上行指示为CRC ERR,以下统称为NACK),表示数据包没有被接收方正确接收,需要发送方对该数据包进行必要的重传。Hybrid Automatic Repeat Request (HARQ) is an error control technology jointly used by Automatic Repeat Request (ARQ) and Forward Error Correction (FEC). Its purpose is to ensure the correct transmission of data packets and improve the reliability of the wireless communication system through the gain generated by the retransmission function and time diversity. After using HARQ, the sender needs to feed back a confirmation message to the receiver to indicate whether the sent data packet has been correctly received by the receiver. If the confirmation message is a positive response ACK (the uplink indication is CRC (Cyclic Redundancy Check, Cyclic Redundancy Check) OK, hereafter collectively referred to as ACK), it means that the data packet has been correctly received by the receiver; if the confirmation message is a negative response NACK ( The uplink indication is CRC ERR (hereinafter collectively referred to as NACK), which indicates that the data packet has not been received correctly by the receiver, and the sender needs to retransmit the data packet as necessary.

下面结合附图对本申请所提供的终端设备节能方法及其装置进行详细地介绍。The energy-saving method and device for terminal equipment provided by this application will be introduced in detail below with reference to the accompanying drawings.
请参见图2,图2是本申请实施例提供的一种终端设备节能方法的流程示意图。该终端设备节能方法由终端设备执行。如图2所示,该方法可以包括但不限于如下步骤:Please refer to Figure 2. Figure 2 is a schematic flowchart of an energy saving method for terminal equipment provided by an embodiment of the present application. The terminal equipment energy saving method is executed by the terminal equipment. As shown in Figure 2, the method may include but is not limited to the following steps:
S21,终端设备为HARQ进程开启重传定时器。S21: The terminal device starts a retransmission timer for the HARQ process.
终端设备可以被配置为DRX模式,以在一段时间里停止监听PDCCH信道,DRX模式可以包括闲置态(IDLE)DRX模式和连接态DRX(Connected DRX,C-DRX)模式。其中,Idle-DRX模式指终端设备处于IDLE状态下的非连续性接收。而C-DRX模式指终端设备处于RRC-CONNECTED状态下的非连续性接收。The terminal device can be configured in DRX mode to stop monitoring the PDCCH channel for a period of time. The DRX mode can include idle DRX mode and connected DRX (Connected DRX, C-DRX) mode. Among them, Idle-DRX mode refers to discontinuous reception when the terminal device is in the IDLE state. The C-DRX mode refers to discontinuous reception when the terminal device is in the RRC-CONNECTED state.
需要说明的是,HARQ进程可以包括上行(uplink,UL)HARQ和下行(downlink,DL)HARQ。It should be noted that the HARQ process may include uplink (UL) HARQ and downlink (downlink, DL) HARQ.
针对每个DLHARQ进程,在配置C-DRX模式的情况下,可以为终端设备向网络设备发送的HARQ反馈(feedback)预留一段到达网络设备的传输时间,在每个DL HARQ进行中配置一个DLHARQ往返时间(Round Trip Time,RTT)定时器(drx-HARQ-RTT-TimerDL)。当终端设备接收到一个下行数据传输包,且CRC校验失败,需要给网络设备反馈否定应答(NACK)信息。当drx-HARQ-RTT-TimerDL正在运行时终端设备无需监听PDCCH。终端设备在drx-HARQ-RTT-TimerDL超时后,且终端为该HARQ进程反馈NACK,则终端可以开启重传下行HARQ进程来接收网络设备的重传数据。但是由于终端设备并不确定网络设备下发HARQ重传数据的具体时间,为了节省终端设备的能耗,终端设备不可能持续等待,因此可以启动重传下行HARQ进程的下行重传定时器(drx-RetransmissionTimerDL),在下行重传定时器超时前持续进行PDCCH监听。For each DLHARQ process, when C-DRX mode is configured, a period of transmission time can be reserved for the HARQ feedback (feedback) sent by the terminal device to the network device to reach the network device, and a DLHARQ is configured during each DL HARQ process. Round Trip Time (RTT) timer (drx-HARQ-RTT-TimerDL). When the terminal device receives a downlink data transmission packet and the CRC check fails, it needs to feed back negative acknowledgment (NACK) information to the network device. The terminal device does not need to listen to the PDCCH when drx-HARQ-RTT-TimerDL is running. After the terminal device times out drx-HARQ-RTT-TimerDL, and the terminal returns NACK to the HARQ process, the terminal can start the retransmission downlink HARQ process to receive retransmitted data from the network device. However, since the terminal device is not sure of the specific time when the network device delivers HARQ retransmission data, in order to save energy consumption of the terminal device, the terminal device cannot continue to wait, so the downlink retransmission timer (drx) of the retransmission downlink HARQ process can be started. -RetransmissionTimerDL), continue to monitor the PDCCH before the downlink retransmission timer expires.
针对每个ULHARQ进程,在配置C-DRX模式的情况下,终端设备向网络设备发送的一个上行数据包后,就可以启动ULHARQ RTT定时器(drx-HARQ-RTT-TimerUL)。在drx-HARQ-RTT-TimerUL超时后,可以开启重传上行HARQ进程,以向网络设备重传数据。但是由于终端设备并不确定向网络设 备重传是否正确,为了节省终端设备的能耗,终端设备不可能持续等待,因此可以启动重传上行HARQ进程的上行重传定时器(drx-RetransmissionTimerDL),在上行重传定时器超时前持续进行PDCCH监听。For each ULHARQ process, when the C-DRX mode is configured, the ULHARQ RTT timer (drx-HARQ-RTT-TimerUL) can be started after the terminal device sends an uplink data packet to the network device. After drx-HARQ-RTT-TimerUL times out, the retransmission uplink HARQ process can be started to retransmit data to the network device. However, since the terminal device is not sure whether the retransmission to the network device is correct, in order to save the energy consumption of the terminal device, the terminal device cannot continue to wait, so the uplink retransmission timer (drx-RetransmissionTimerDL) of the retransmission uplink HARQ process can be started.

S22,终端设备监听低功耗唤醒信号LP-WUS。S22: The terminal device monitors the low-power wake-up signal LP-WUS.
本申请实施例中,终端设备为节能状态。低功耗唤醒信号(Low power wake up signal,LP-WUS)用于指示终端设备从节能状态进入监听PDCCH的状态。In this embodiment of the present application, the terminal device is in an energy-saving state. Low power wake up signal (LP-WUS) is used to instruct the terminal device to enter the state of monitoring PDCCH from the energy saving state.
本公开中,在终端设备被配置为C-DRX模式的情况下,且为HARQ进程开启重传定时器的情况下,为了降低终端设备的能耗,延长终端设备的续航能力,终端设备可以进入低功耗唤醒信号(Low power wake up signal,LP-WUS)监听状态,并且终端设备进入节能状态,即终端设备的主机进入节能状态。例如,终端设备的主机进入睡眠状态。In this disclosure, when the terminal device is configured in C-DRX mode and the retransmission timer is enabled for the HARQ process, in order to reduce the energy consumption of the terminal device and extend the battery life of the terminal device, the terminal device can enter Low power wake up signal (LP-WUS) listening state, and the terminal device enters the energy-saving state, that is, the host of the terminal device enters the energy-saving state. For example, the host of the terminal device goes to sleep.
可选地,睡眠状态可以包括:深度睡眠状态(deep sleep)、浅睡眠状态(light sleep)、微睡眠状态(micro sleep)的一种。可选地,终端设备可以处于microsleep,需要说明的是,micro sleep状态是处于较浅层次睡眠的一种睡眠状态,可以快速重新进入唤醒。需要说明的是,终端设备在深度睡眠状态的功耗低于在浅睡眠状态的功耗,微睡眠状态的功耗低于浅睡眠状态的功耗,终端设备在微睡眠状态下的功耗要低于监听PDCCH的状态下的功耗。可选地,还可以限制监听PDCCH状态下的功耗与微睡眠状态下的功耗之前的差值大于设定值。Optionally, the sleep state may include: one of deep sleep state (deep sleep), light sleep state (light sleep), and micro sleep state (micro sleep). Optionally, the terminal device can be in microsleep. It should be noted that the micro sleep state is a sleep state in a shallower level of sleep and can quickly re-enter and wake up. It should be noted that the power consumption of the terminal device in the deep sleep state is lower than the power consumption in the light sleep state. The power consumption in the micro sleep state is lower than the power consumption in the light sleep state. The power consumption of the terminal device in the micro sleep state is higher than that in the light sleep state. Lower than the power consumption in the state of monitoring PDCCH. Optionally, the difference between the power consumption in the PDCCH monitoring state and the power consumption in the micro-sleep state can also be limited to be greater than a set value.
本公开中,在终端设备处于微睡眠状态时,监听到LP-WUS后能够快速的从睡眠态转换为正常工作的激活态,因此转换时间很短,缩短终端设备从节能状态进入重新唤醒的时间,便于尽快进行PDCCH监听,避免信息或数据的丢失。In this disclosure, when the terminal device is in the micro-sleep state, it can quickly switch from the sleep state to the normal working activation state after monitoring LP-WUS. Therefore, the conversion time is very short, and the time for the terminal device to re-awaken from the energy-saving state is shortened. , to facilitate PDCCH monitoring as soon as possible and avoid the loss of information or data.
可选地,终端设备也可以在被配置为C-DRX模式的情况下,同时被配置为跳过监听PDCCH的状态。可选地,终端设备可以接收网络设备下发的下行控制信息(Downlink Control Information,DCI),从该DCI可以指示终端设备在接下来的设定时段内跳过PDCCH(PDCCH skipping)的监听,设定时间段的可选值由高层信令配置。需要说明的是,终端设备即使配置了PDCCH skipping,该PDCCH skipping并不能应用于重传定时器运行期间。Optionally, when the terminal device is configured in the C-DRX mode, it may also be configured to skip monitoring the PDCCH at the same time. Optionally, the terminal device can receive downlink control information (DCI) issued by the network device, and the DCI can instruct the terminal device to skip monitoring of PDCCH (PDCCH skipping) in the next set period. Optional values for a certain time period are configured by high-level signaling. It should be noted that even if the terminal device is configured with PDCCH skipping, the PDCCH skipping cannot be applied while the retransmission timer is running.
本公开中,终端设备上设置有低功耗接收机,在主机处于节能状态时,开启该低功耗接收机专门接收网络设备发送的LP WUS信号,以此确定是否需要重新启动主机。由于低功耗接收机的功率很小可以达到终端设备节能的目的。In this disclosure, a low-power receiver is provided on the terminal device. When the host is in an energy-saving state, the low-power receiver is turned on to specifically receive the LP WUS signal sent by the network device to determine whether the host needs to be restarted. Since the power of the low-power receiver is very small, the purpose of energy saving of the terminal equipment can be achieved.
本公开中,由于终端设备处于节能状态,不会对PDCCH进行监听,此种情况下,为了使终端设备在节能状态下可以监听到LP-WUS,可选地,网络设备发送的LP-WUS可以为一个序列信号,该序列信号往往自相关较强且互相关较差,通过自相关检测,实现对LP-WUS的监听,例如,LP-WUS可以为一个0和1组成的序列信号。可选地,终端设备可以通过检测载波的能量,若能量低于一定阈值,则可以确定该载波的序列信号为‘0’0,若能量高于设定阈值,则可以确定该载波的序列信号为‘1’。例如,‘0’可以用于指示终端设备在下一个DRX周期无需要唤醒,‘1’用于指示终端设备在下一个DRX周期需要唤醒,以进入监听PDCCH状态。In this disclosure, since the terminal device is in the energy-saving state, the PDCCH will not be monitored. In this case, in order to enable the terminal device to monitor the LP-WUS in the energy-saving state, optionally, the LP-WUS sent by the network device can As a sequence signal, the sequence signal often has strong autocorrelation and poor cross-correlation. Through autocorrelation detection, the monitoring of LP-WUS can be realized. For example, LP-WUS can be a sequence signal composed of 0 and 1. Alternatively, the terminal device can detect the energy of the carrier. If the energy is lower than a certain threshold, it can determine that the sequence signal of the carrier is '0'0. If the energy is higher than the set threshold, it can determine the sequence signal of the carrier. is '1'. For example, '0' can be used to indicate that the terminal equipment does not need to wake up in the next DRX cycle, and '1' can be used to indicate that the terminal equipment needs to wake up in the next DRX cycle to enter the PDCCH listening state.
本公开实施例中,可以在重传定时器开始后,进入LP-WUS监听状态和节能状态,在节能状态下可以减少不必要的PDCCH盲检,因而能够节能终端能耗。进一步地,可以设置终端设备的节能状态为 微睡眠状态,在微睡眠状态下在监听到LP-WUS终端设备可以快速地从节能态转换为正常工作的激活态,转换时间很短,缩短终端设备从节能状态进入重新唤醒的时间,便于尽快进行PDCCH监听,避免信息或数据的丢失。In the embodiment of the present disclosure, after the retransmission timer starts, the LP-WUS listening state and the energy-saving state can be entered. In the energy-saving state, unnecessary PDCCH blind detection can be reduced, thereby saving terminal energy consumption. Furthermore, the energy-saving state of the terminal device can be set to the micro-sleep state. In the micro-sleep state, after monitoring the LP-WUS terminal device, the terminal device can quickly switch from the energy-saving state to the normal working activation state. The conversion time is very short, shortening the terminal equipment's operation time. The time to re-awaken from the energy-saving state is to facilitate PDCCH monitoring as soon as possible to avoid the loss of information or data.

本公开中,在终端设备被配置为C-DRX模式的情况下,且为HARQ进程开启重传定时器的情况下,为了降低终端设备的能耗,延长终端设备的续航能力,终端设备可以进入LP-WUS监听状态,并且终端设备进入节能状态,即终端设备的主机进入节能状态。例如,终端设备的主机进入睡眠状态。In this disclosure, when the terminal device is configured in C-DRX mode and the retransmission timer is enabled for the HARQ process, in order to reduce the energy consumption of the terminal device and extend the battery life of the terminal device, the terminal device can enter LP-WUS listening state, and the terminal device enters the energy-saving state, that is, the host of the terminal device enters the energy-saving state.

可选地,本公开实施例提供的终端设备节能方法还可以包括以下步骤:Optionally, the terminal device energy saving method provided by the embodiment of the present disclosure may also include the following steps:

The terminal device times out after drx-HARQ-RTT-TimerDL and the terminal is HARQ If the process returns NACK, the terminal can start the retransmission downlink HARQ process to receive retransmitted data from the network device. However, since the terminal device is not sure of the specific time for the network device to issue HARQ retransmission data, in order to save the energy consumption of the terminal device, the terminal device cannot continue to wait, so the drx-RetransmissionTimerDL of the retransmission downlink HARQ process can be started.
针对每个ULHARQ进程,在配置C-DRX模式的情况下,终端设备向网络设备发送的一个上行数据包后,就可以启动drx-HARQ-RTT-TimerUL。在drx-HARQ-RTT-TimerUL超时后,可以开启重传上行HARQ进程,以向网络设备重传数据。但是由于终端设备并不确定向网络设备重传是否正确,为了节省终端设备的能耗,终端设备不可能持续等待,因此可以启动drx-RetransmissionTimerDL。For each ULHARQ process, when C-DRX mode is configured, drx-HARQ-RTT-TimerUL can be started after the terminal device sends an uplink data packet to the network device. After drx-HARQ-RTT-TimerUL times out, the retransmission uplink HARQ process can be started to retransmit data to the network device. However, since the terminal device is not sure whether the retransmission to the network device is correct, in order to save the energy consumption of the terminal device, the terminal device cannot wait continuously, so drx-RetransmissionTimerDL can be started.
可选地,针对上行HARQ进程,可能存在异常情况,例如下行HARQ进程中,可能会存在终端设备CRC校验失败,或者预设时间内未收到数据的情况,网络设备可以接收到终端设备反馈的NACK,网络设备可以确定数据传输异常,此种情况下网络设备可以调度下行HAQ进程进行数据重传。例如,在上行HARQ进程中,可能会存在数据上传失败的情况,即网络设备在预设时间内未接收到上传的数据,则可以确定数据传输异常,此种情况下网络设备可以调度下行HAQ进程进行数据重传。Optionally, for the uplink HARQ process, there may be abnormal situations. For example, in the downlink HARQ process, the terminal device may fail the CRC check, or the data may not be received within the preset time. The network device can receive feedback from the terminal device. NACK, the network device can determine that the data transmission is abnormal. In this case, the network device can schedule the downlink HAQ process to retransmit the data. For example, in the uplink HARQ process, data upload may fail. That is, the network device does not receive the uploaded data within the preset time, and it can be determined that the data transmission is abnormal. In this case, the network device can schedule the downlink HAQ process. Perform data retransmission.
针对上行HARQ进程,网络设备可以通过PDCCH向终端设备发送调度上行HARQ进程的重传调度信息。针对下行HARQ进程,网络设备可以向终端设备发送调度下行HARQ进程的重传调度信息。For the uplink HARQ process, the network device can send retransmission scheduling information for scheduling the uplink HARQ process to the terminal device through the PDCCH.
