Description

管理定时器的方法和终端设备Method and terminal device for managing timers 技术领域Technical field
本发明实施例涉及通信领域，并且更具体地，涉及管理定时器的方法和终端设备。Embodiments of the present invention relate to the field of communications, and, more particularly, to a method and a terminal device for managing a timer.
背景技术Background technique
现有技术中，基于包的数据流通常是突发性的。换句话说，终端设备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。由此，如果终端设备一直对物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)盲检，会导致终端设备的功耗过大。In the prior art, packet based data streams are typically bursty. In other words, the terminal device has data transmission for a period of time, but there is no data transmission for a long period of time. Therefore, if the terminal device blindly checks the physical downlink control channel (PDCCH), the power consumption of the terminal device is excessive.
为了解决上述问题，在长期演进(Long Term Evolution，LTE)中，提出了非连续接收(Discontinuous Reception，DRX)的概念。具体地，在终端设备没有数据传输的时候，可以通过停止接收物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)(此时会停止PDCCH盲检)来降低功耗，从而提升电池使用时间。In order to solve the above problem, in the Long Term Evolution (LTE), the concept of Discontinuous Reception (DRX) is proposed. Specifically, when the terminal device does not have data transmission, the power consumption can be reduced by stopping receiving the Physical Downlink Control Channel (PDCCH) (the PDCCH blind detection is stopped at this time), thereby improving battery life.
更具体地，网络设备会为处于无线资源控制连接(Radio Resource Control_CONNECTED，RRC_CONNECTED)态的终端设备配置一个DRX周期(cycle)。More specifically, the network device configures a DRX cycle for the terminal device in the Radio Resource Control_CONNECTED (RRC_CONNECTED) state.
其中，DRX cycle由激活期(On Duration)和休眠期(Opportunity for DRX)组成，在On Duration时间内，终端设备监听并接收PDCCH；在Opportunity for DRX时间内，终端设备不接收PDCCH以减少功耗。The DRX cycle is composed of an On Duration and an Opportunity for DRX. During the On Duration, the terminal device monitors and receives the PDCCH. During the Opportunity for DRX, the terminal device does not receive the PDCCH to reduce power consumption. .
然而，在非授权频段进行DRX操作时，有可能On Duration的时间会受到网络侧先侦听后传输(Listen Before Talk，LBT)的影响。However, when DRX operation is performed in an unlicensed band, it is possible that the On Duration time will be affected by the Listening Before Talk (LBT) on the network side.
例如，在一个On Duration时间内，网络有LBT失败不能发送PDCCH，则UE不能启动DRX去激活定时器(drx-InactivityTimer)，这样On Duration就会在DRX-激活期定时器(drx-onDurationTimer)失效的时候结束。然而，如果没有LBT的影响，网络正常发送PDCCH，UE收到PDCCH能够启动drx-InactivityTimer,这样On Duration的时间会随着drx-onDurationTimer的启动而延长。For example, if the network has LBT failure and cannot send PDCCH within one On Duration time, the UE cannot start the DRX deactivation timer (drx-InactivityTimer), so the On Duration will be invalid in the DRX-active period timer (drx-onDurationTimer). The time is over. However, if there is no impact of the LBT, the network normally transmits the PDCCH, and the UE receives the PDCCH to start the drx-InactivityTimer, so that the On Duration time is extended with the start of the drx-onDurationTimer.

具体实施方式Detailed ways
图1是本发明实施例的应用场景的示意图。FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the present invention.
如图1所示，通信***100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。As shown in FIG. 1, communication system 100 can include terminal device 110 and network device 120. Network device 120 can communicate with terminal device 110 over an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.
但是，基于包的数据流通常是突发性的。换句话说，终端设备100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。由此，如果终端设备100一直对物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)盲检，会导致终端设备的功耗过大。However, packet-based data streams are often bursty. In other words, the terminal device 100 has data transmission for a period of time, but there is no data transmission for a long period of time. Therefore, if the terminal device 100 blindly checks the physical downlink control channel (PDCCH), the power consumption of the terminal device is excessive.
虽然，在长期演进(Long Term Evolution，LTE)中，提出了非连续接收(Discontinuous Reception，DRX)的概念。具体的，DRX的主要想法是：网络可以配置终端在网络预知的时间醒来(DRX ON)，终端监听下行控制信道；同时网络也可以配置终端在网络预知的时间睡眠(DRX OFF)，即，终端设备不用监听下行控制信道。这样，如果有数据要传给终端，网路可以 在终端DRX ON的时间内调度终端，而DRC OFF时间内，由于射频关闭，可以减少终端耗电。Although, in Long Term Evolution (LTE), the concept of Discontinuous Reception (DRX) is proposed. Specifically, the main idea of the DRX is that the network can configure the terminal to wake up at the network foreseen (DRX ON), and the terminal listens to the downlink control channel; at the same time, the network can also configure the terminal to sleep at the network for a predetermined time (DRX OFF), ie, The terminal device does not need to listen to the downlink control channel. In this way, if there is data to be transmitted to the terminal, the network can schedule the terminal within the time of the terminal DRX ON, and during the DRC OFF time, the power consumption of the terminal can be reduced due to the radio frequency being turned off.
但是，终端设备在非授权频谱上传输数据需要满足一些非授权频谱规范的要求的。例如，先侦听后传输(Listen Before Talk，LBT)。However, the transmission of data by the terminal equipment on the unlicensed spectrum needs to meet the requirements of some unlicensed spectrum specifications. For example, Listen Before Talk (LBT).
其中，先侦听后传输(Listen Before Talk，LBT)可以理解为：终端设备在传输数据之前需要侦听信道，如果检测到的能量低于某个门限值，则认为终端可以在该信道上传输数据。The Listening Before Talk (LBT) can be understood as: the terminal device needs to listen to the channel before transmitting the data, and if the detected energy is below a certain threshold, the terminal can be considered to be on the channel. transfer data.
可以发现：在非授权频段进行DRX操作时，有可能On Duration的时间会受到网络侧先侦听后传输(Listen Before Talk，LBT)的影响。It can be found that when the DRX operation is performed in the unlicensed band, it is possible that the On Duration time is affected by the Listening Before Talk (LBT) on the network side.
例如，在一个On Duration时间内，网络有LBT失败不能发送PDCCH，则UE不能启动DRX去激活定时器(drx-InactivityTimer)，这样On Duration就会在DRX-激活期定时器(drx-onDurationTimer)失效的时候结束。然而，如果没有LBT的影响，网络正常发送PDCCH，UE收到PDCCH能够启动drx-InactivityTimer,这样On Duration的时间会随着drx-onDurationTimer的启动而延长。For example, if the network has LBT failure and cannot send PDCCH within one On Duration time, the UE cannot start the DRX deactivation timer (drx-InactivityTimer), so the On Duration will be invalid in the DRX-active period timer (drx-onDurationTimer). The time is over. However, if there is no impact of the LBT, the network normally transmits the PDCCH, and the UE receives the PDCCH to start the drx-InactivityTimer, so that the On Duration time is extended with the start of the drx-onDurationTimer.
因此，本发明实施例中提供了一种管理定时器的方法，能够使得工作在非授权频段下的终端设备，在DRX的On Duration随着PDCCH的监测情况动态调整，进而提高用户体验。Therefore, in the embodiment of the present invention, a method for managing a timer is provided, which enables a terminal device operating in an unlicensed frequency band to dynamically adjust the On Duration of the DRX according to the monitoring condition of the PDCCH, thereby improving the user experience.

Specifically, the terminal device 110 can communicate with one or more core networks (Core Network) via a radio access network (RAN), and can also be referred to as an access terminal, a user equipment (User Equipment, UE), Subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device.

图2是本发明实施例的管理定时器的示意性流程图。FIG. 2 is a schematic flowchart of a management timer according to an embodiment of the present invention.
具体地，如图2该，该方法包括：Specifically, as shown in FIG. 2, the method includes:
210，该终端设备在该DRX周期的第一激活期的起始时刻，启动该第一定时器。210. The terminal device starts the first timer at a start time of the first activation period of the DRX cycle.
220，该终端设备在该第一激活期的起始时刻到该第一定时器的失效时刻之间，在该非授权频段的载波上，未侦听到PDCCH时，重新确定该第一定时器的时长。220. The terminal device re-determines the first timer when the PDCCH is not detected on the carrier of the unlicensed band between the start time of the first activation period and the failure time of the first timer. The length of time.
230，该终端设备在该第一激活期之后相邻的第二激活期的起始时刻，重新启动该第一定时器。230. The terminal device restarts the first timer at a start time of an adjacent second activation period after the first activation period.
具体而言，在该终端设备在第一激活期的起始时刻，启动第一定时器之前，该终端设备确定该第一激活期的起始时刻。进而，该终端设备在该第一激活期的起始时刻，启动该第一定时器，并在该第一激活期的起始时刻到该第一定时器的失效时刻之间，在该非授权频段的载波上，侦听到PDCCH。如果该终端设备在该第一激活期的起始时刻到该第一定时器的失效时刻之间，在该非授权频段的载波上，未侦听到PDCCH时，则该终端设备重新确定该第一定时器的时长，并在该第一激活期之后相邻的第二激活期的起始时刻，重新启动该第一定时器。Specifically, before the terminal device starts the first timer at the start time of the first activation period, the terminal device determines a start time of the first activation period. Further, the terminal device starts the first timer at a start time of the first activation period, and between the start time of the first activation period and the failure time of the first timer, in the unauthorized On the carrier of the frequency band, the PDCCH is detected. If the terminal device does not detect the PDCCH on the carrier of the unlicensed band between the start time of the first activation period and the failure time of the first timer, the terminal device re-determines the The duration of a timer, and restarting the first timer at the beginning of the second active period adjacent to the first activation period.
由此，使得工作在非授权频段下的终端设备，基于PDCCH的监测情况动态调整第一定时器的时长，进而调整DRX的激活期的时长，能够降低LBT对DRX的影响，提高用户体验。Therefore, the terminal device operating in the unlicensed frequency band dynamically adjusts the duration of the first timer based on the monitoring condition of the PDCCH, thereby adjusting the duration of the DRX activation period, thereby reducing the impact of the LBT on the DRX and improving the user experience.
更具体地，该终端设备将满足以下任一个公式的子帧的起始时刻，确定为该第一激活期的起始时刻：More specifically, the terminal device determines the start time of the subframe that satisfies any of the following formulas as the start time of the first activation period:
[(SFN*10)+A]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-Short Cycle)和[(SFN*10)+A]modulo(drx-LongCycle)＝drx-StartOffset；[(SFN*10)+A]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-Short Cycle) and [(SFN*10)+A]modulo(drx-LongCycle)=drx-StartOffset;
其中，该SFN表示***帧号，该A表示子帧号，该drx-ShortCycle和该drx-LongCycle均表示该DRX周期所占用的子帧数，该modulo表示求模运算，该drx-StartOffset表示该DRX周期的起始子帧号。The SFN represents a system frame number, and the A represents a subframe number, and the drx-ShortCycle and the drx-LongCycle both indicate the number of subframes occupied by the DRX cycle, and the modulo represents a modulo operation, and the drx-StartOffset indicates the The starting subframe number of the DRX cycle.
应理解，本申请实施例中提供的管理定时器的方法可以应用于工作在非授权频段的终端设备，该终端设备配置有DRX周期和第一定时器。It should be understood that the method for managing a timer provided in this embodiment of the present application may be applied to a terminal device operating in an unlicensed frequency band, where the terminal device is configured with a DRX cycle and a first timer.
需要注意的是，本发明实施例中的该第一激活期可以指该DRX周期的任一激活期。It should be noted that the first activation period in the embodiment of the present invention may refer to any activation period of the DRX cycle.
具体地，媒体介入控制(Media Access Control，MAC)实体(entity)由无线资源控制(Radio Resource Control，RRC)配置DRX功能，用于控制终端监测PDCCH的行为。Specifically, the Media Access Control (MAC) entity is configured by the Radio Resource Control (RRC) to configure the DRX function, and is used to control the behavior of the terminal to monitor the PDCCH.
例如，如图3所述，网络设备为终端设备配置的DRX cycle由激活期(On Duration)和休眠期(Opportunity for DRX)组成，在RRC连接态(RRC CONNECTED)模式下，如果终端配置了DRX功能，MAC entity可以在On Duration时间内，终端设备监听并接收PDCCH；在Opportunity for DRX时间内，终端设备不接收PDCCH以减少功耗。For example, as shown in FIG. 3, the DRX cycle configured by the network device for the terminal device is composed of an On Duration and an Opportunity for DRX. In the RRC CONNECTED mode, if the terminal is configured with DRX, Function: The MAC entity can monitor and receive the PDCCH in the On Duration time; during the Opportunity for DRX, the terminal device does not receive the PDCCH to reduce power consumption.
本发明实施例中，处于休眠期的终端设备，只是不接收PDCCH，但是可以接收来自其它物理信道的数据。本发明实施例不作具体限定，例如，该终端设备可以接收物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、确认/非确认(ACK/NACK)等。又例如，在半永久性调度(Semi-Persistent Scheduling，SPS)中，该终端设备可以接收周期性配置的PDSCH数据。In the embodiment of the present invention, the terminal device in the dormant period only does not receive the PDCCH, but can receive data from other physical channels. The embodiment of the present invention does not specifically limit. For example, the terminal device can receive a Physical Downlink Shared Channel (PDSCH), an acknowledgment/non-acknowledgement (ACK/NACK), and the like. For another example, in Semi-Persistent Scheduling (SPS), the terminal device can receive periodically configured PDSCH data.
还应理解，该第一定时器包括但不限于以下定时器中的任一种：It should also be understood that the first timer includes, but is not limited to, any of the following timers:
DRX-激活期定时器、重传定时器和DRX-混合自动重传请求HARQ-往返时间RTT定时器。DRX-active period timer, retransmission timer, and DRX-hybrid automatic repeat request HARQ-round-trip time RTT timer.
下面对该终端设备重新确定该第一定时器的时长的实现方式进行示例性说明：The following is an exemplary description of how the terminal device re-determines the duration of the first timer:
在一个实施例中，该终端设备确定偏置时长；该终端设备可以将该第一时长与该偏置时长的和，确定为该第一定时器的时长，第一时长为该第一激活期的起始时刻到该第一定时器的失效时刻之间的时长。In an embodiment, the terminal device determines the offset duration; the terminal device may determine the sum of the first duration and the offset duration as the duration of the first timer, where the first duration is the first activation period The length of time between the start time and the failure time of the first timer.
具体而言，当终端设备配置了DRX，且工作在非授权频段，如果在当前on duration期间没有监测到PDCCH，则在下一个on duration启动时，其on duration时长增加一个配置的偏置(offset)时长，直到在on duration期间监测到PDCCH。Specifically, when the terminal device is configured with DRX and operates in an unlicensed band, if no PDCCH is detected during the current on duration, the on duration of the next duration is increased by a configured offset (offset). Duration, until the PDCCH is monitored during the on duration.
换句话说，如果该终端设备没有监听到PDCCH，则终端进入DRX关闭(off)阶段(即停止监听PDCCH)，同时给当前配置的该第一定时器增加一个配置的offset时长。In other words, if the terminal device does not monitor the PDCCH, the terminal enters the DRX off phase (ie, stops monitoring the PDCCH), and adds a configured offset duration to the currently configured first timer.
进一步地，该偏置时长可以为网络设备为该终端设备配置的时长。Further, the offset duration may be a duration configured by the network device for the terminal device.
本申请实施例中，终端设备可以根据该第二激活期内对PDCCH的侦听结果，进一步确定终端设备在该第二激活期之后相邻的第三激活期内，该第一定时器的时长。In the embodiment of the present application, the terminal device may further determine, according to the interception result of the PDCCH in the second activation period, the duration of the first timer in the third activation period that is adjacent to the terminal device after the second activation period. .
例如，该终端设备在该第二激活期内侦听到PDCCH时，可以将该第一定时器的时长重置为网络设备配置的初始配置时长。For example, when the terminal device detects the PDCCH during the second activation period, the duration of the first timer may be reset to the initial configuration duration of the network device configuration.
具体而言，如果该终端设备在on duration期间监测到PDCCH，则该第一定时器的时长重置成网络设备为终端设备配置的时长，即终端将所有叠加到该第一定时器上的偏置(offset)全部去掉。Specifically, if the terminal device monitors the PDCCH during the on duration, the duration of the first timer is reset to the duration configured by the network device for the terminal device, that is, the terminal adds all the biases to the first timer. All offsets are removed.
又例如，该终端设备在该第二激活期的起始时刻到该第一定时器的失效时刻之间，在该非授权频段的载波上，未侦听到PDCCH时，可以重新确定该第一定时器的时长；该终端设备在该第二激活期之后相邻的第三激活期的起始时刻，重新启动该第一定时器。For example, the terminal device may re-determine the first time when the PDCCH is not detected on the carrier of the unlicensed band between the start time of the second activation period and the failure time of the first timer. The duration of the timer; the terminal device restarts the first timer at a start time of the adjacent third activation period after the second activation period.
本申请实施例中，为了避免该第一定时器的时长过大。In this embodiment of the present application, in order to avoid the duration of the first timer being too large.
可选的，可以使得该第一定时器的时长小于或等于网络设备配置的最大时间长度。换句话说，该第一定时器的时长加上所以可能的偏置(offset)的总长不能大于一个网络设备为该终端设备配置的时间长度。Optionally, the duration of the first timer may be less than or equal to a maximum length of time configured by the network device. In other words, the duration of the first timer plus the total length of the possible offset cannot be greater than the length of time that a network device is configured for the terminal device.
