- the term “plurality” refers to two or more than two, and other quantifiers are similar.
- Figure 1 is a schematic diagram of a cellular communication network; in traditional cellular network communication, uplink/downlink data and control information are transmitted between a terminal and a network-side device through a Uu interface.
- the transmission of uplink and downlink data is controlled by the base station (evolutional Node B, eNB) scheduler.
- the scheduler determines When scheduling a user, it will notify the terminal on which resource to send or receive data through the control channel.
- the terminal User Equipment, UE
- a common working mode is that the terminal continuously monitors the control channel, and schedules the downlink for each control channel.
- the subframes of the control channel are all analyzed to determine whether they are scheduled.
- This working method can achieve higher efficiency when the terminal data volume is large and may be frequently scheduled. However, for some services, the data The arrival frequency is low, resulting in a small number of times the terminal is scheduled. If the terminal continues to monitor the control channel, it will undoubtedly increase its power consumption.
- the cellular network communication system adopts discontinuous reception (Discontinuous Reception, DRX) working mode, in this working mode, the terminal periodically monitors the control channel, thus achieving the purpose of power saving.
- DRX discontinuous Reception
- the terminal UE shall monitor the PDCCH (UE shall monitor PDCCH).
- the duration represents the time period during which the UE monitors the control channel, during which the radio frequency channel is turned on, and continuously monitors the control channel; except for other times (such as DRX opportunity (Opportunity for DRX)), the UE is in Sleep In this state, its RF link will be shut down and no longer monitor the control channel to save power.
- On Duration is a periodic occurrence (Cycle), and the specific period is implemented by the eNB configuration.
- the DRX mechanism of the cellular network considers the arrival model of data services, that is, the arrival of data packets is sudden (it can be understood that once a data packet arrives, more packets will arrive continuously in a short period of time).
- the DRX process adopts a variety of timers, which are combined with the Hybrid Automatic Repeat Request (HARQ) process to achieve better power saving performance.
- HARQ Hybrid Automatic Repeat Request
- the DRX related timers are as follows:
- DRX duration timer (drx-on Duration Timer): The time when the UE periodically wakes up to monitor the control channel, as shown in Figure 2.
- Short DRX cycle Timer In order to better match the characteristics of data service arrival, the cellular network communication system supports the configuration of two DRX cycles: long cycle and short cycle. The on duration timer of the two cycles is the same, but the sleep time is different. In the short cycle, the sleep time is relatively shorter, and the UE can monitor the control channel again faster. Long cycle is mandatory and is the initial state of the DRX process; short cycle is optional. The short DRX cycle timer sets the duration of the short cycle. After the Short cycle timer times out, the UE will use the Long cycle.
- DRX inactivity timer (drx-Inactivity Timer): After DRX is configured, when the UE receives the control signaling of HARQ initial transmission within the time allowed to monitor the control channel (the time the UE monitors the control channel (Active Time)) Turn on this timer, and until the timer expires, the UE continuously monitors the control channel. If the UE receives the control signaling of HARQ initial transmission before the drx-Inactivity Timer times out, it will terminate and restart the drx-Inactivity Timer.
- HARQ round-trip delay (Round-Trip Time, RTT) timer (HARQ RTT Timer): divided into DRX's HARQ downlink round-trip delay timer (drx-HARQ-RTT-Timer DL) and DRX's HARQ uplink round-trip delay timer
- the purpose is to make it possible for the UE not to monitor the control channel before the next retransmission, so as to achieve better power saving effect.
- PUCCH Physical Uplink Control Channel
- the UE If the data in the corresponding HARQ process is not successfully decoded after the previous HARQ transmission (the UE feeds back a negative response (Negative-Acknowledgment, NACK)), after the drx-HARQ-RTT-Timer DL times out, the UE turns on the downlink retransmission timing of DRX timer (drx-RetransmissionTimer DL). If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (UE feedback response (Acknowledgment, ACK)), after the drx-HARQ-RTT-Timer DL timer expires, the UE does not start the drx-Retransmission Timer DL. If only drx-HARQ-RTT-Timer DL is currently running, the UE does not monitor the control channel.
- NACK negative response
- HARQ retransmission timer (HARQ retransmission Timer): divided into the HARQ uplink retransmission timer (drx-RetransmissionTimer DL) of DRX or the HARQ downlink retransmission timer (drx-RetransmissionTimer UL) of DRX.
- the UE monitors the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.

本公开涉及通信技术领域,尤其涉及一种直通链路激活状态的处理方法、装置及终端。The present disclosure relates to the field of communication technologies, and in particular, to a method, an apparatus, and a terminal for processing the activation state of a direct link.
对于直接通信接口,目前不支持节电机制,因此终端耗电量会比较快。为了解决耗电问题,蜂窝网络通信系统采用了非连续接收(Discontinuous Reception,DRX)工作模式,在这种工作模式下,终端周期性的对控制信道进行监听,因而达到节电的目的。但是,在这种工作模式下,由于终端周期性的对控制信道进行监听,也即是终端在持续时间(On duration)内连续监听控制信道,在除去On duration之外的其它时间处于睡眠(Sleep)状态,不再监听控制信道,这样终端在直通链路的DRX/非连续发送(Discontinuous Transmission,DTX)工作模式下,可能存在有传输需求时而不能进行信息传输的情况,从而会造成传输性能的损失。For the direct communication interface, the power saving mechanism is not currently supported, so the terminal consumes power faster. In order to solve the problem of power consumption, the cellular network communication system adopts a discontinuous reception (Discontinuous Reception, DRX) working mode. In this working mode, the terminal periodically monitors the control channel, thus achieving the purpose of saving power. However, in this working mode, since the terminal periodically monitors the control channel, that is, the terminal continuously monitors the control channel within the duration (On duration), and is in sleep (Sleep) at other times except the On duration. ) state, and no longer monitor the control channel, so that the terminal may not be able to transmit information when there is a transmission demand in the DRX/Discontinuous Transmission (DTX) working mode of the direct link, which will cause transmission performance. loss.

Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.
如图1是蜂窝通信网络示意图;传统的蜂窝网络通信,终端和网络侧设备之间通过Uu接口进行上/下行数据和控制信息的传输。Figure 1 is a schematic diagram of a cellular communication network; in traditional cellular network communication, uplink/downlink data and control information are transmitted between a terminal and a network-side device through a Uu interface.
在基于共享信道的移动通信系统中,例如长期演进(Long Term Evolution,LTE)中,上下行数据的传输由基站(演进型网络设备(evolutional Node B,eNB)调度器负责控制,当调度器确定调度某用户时,将通过控制信道通知终端在何种资源上发送或接收数据。终端(User Equipment,UE)监听控制信道,当检测到包含自己的调度信息时,根据控制信道上的指示完成数据的发送(上行)或接收(下行)。在激活状态下,由于终端不确定eNB何时对其进行调度,因此一种常见的工作模式为,终端连续监听控制信道,对每个包含其下行调度控制信道的子帧都进行解析,以判断是否被调度。这种工作方式在终端数据量较大,可能被频繁调度的情况下能获得较高的效率。然而对某些业务而言,数据的到达频率较低,导致终端被调度的次数也较小,如果终端仍然连续监听控制信道,无疑会增加其耗电量。为了解决耗电问题,蜂窝网络通信系统采用了非连续接收(Discontinuous Reception,DRX)工作 模式,在这种工作模式下,终端周期性的对控制信道进行监听,因而达到节电的目的。In a shared channel-based mobile communication system, such as Long Term Evolution (LTE), the transmission of uplink and downlink data is controlled by the base station (evolutional Node B, eNB) scheduler. When the scheduler determines When scheduling a user, it will notify the terminal on which resource to send or receive data through the control channel. The terminal (User Equipment, UE) monitors the control channel, and when it detects its own scheduling information, completes the data according to the instructions on the control channel In the active state, since the terminal is not sure when the eNB will schedule it, a common working mode is that the terminal continuously monitors the control channel, and schedules the downlink for each control channel. The subframes of the control channel are all analyzed to determine whether they are scheduled. This working method can achieve higher efficiency when the terminal data volume is large and may be frequently scheduled. However, for some services, the data The arrival frequency is low, resulting in a small number of times the terminal is scheduled. If the terminal continues to monitor the control channel, it will undoubtedly increase its power consumption. In order to solve the problem of power consumption, the cellular network communication system adopts discontinuous reception (Discontinuous Reception, DRX) working mode, in this working mode, the terminal periodically monitors the control channel, thus achieving the purpose of power saving.
DRX的基本原理如图2所示。在DRX周期(Cycle)终端UE应监控PDCCH(UE shall monitor PDCCH)。其中,持续时间(On duration)表示UE监听控制信道的时间段,其间射频通道打开,并连续监听控制信道;除去On duration之外的其它时间(如DRX机会(Opportunity for DRX)),UE处于Sleep状态,其射频链路将被关闭,不再监听控制信道,以达到省电的目的。On Duration都是周期性出现(Cycle),具体周期由eNB配置实现。The basic principle of DRX is shown in Figure 2. In the DRX cycle (Cycle), the terminal UE shall monitor the PDCCH (UE shall monitor PDCCH). Among them, the duration (On duration) represents the time period during which the UE monitors the control channel, during which the radio frequency channel is turned on, and continuously monitors the control channel; except for other times (such as DRX opportunity (Opportunity for DRX)), the UE is in Sleep In this state, its RF link will be shut down and no longer monitor the control channel to save power. On Duration is a periodic occurrence (Cycle), and the specific period is implemented by the eNB configuration.
蜂窝网络的DRX机制考虑了数据业务的到达模型,即数据分组的到达是突发的(可以理解为,一旦有数据分组到达,那么会在较短时间内连续到达较多的分组)。为了适应这种业务到达特点,DRX过程采用了多种定时器,并与混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)过程相结合,以期达到更好的节电性能。The DRX mechanism of the cellular network considers the arrival model of data services, that is, the arrival of data packets is sudden (it can be understood that once a data packet arrives, more packets will arrive continuously in a short period of time). In order to adapt to the arrival characteristics of such services, the DRX process adopts a variety of timers, which are combined with the Hybrid Automatic Repeat Request (HARQ) process to achieve better power saving performance.
DRX相关定时器如下:The DRX related timers are as follows:
DRX的持续时间定时器(drx-on Duration Timer):UE周期性醒来监听控制信道的时间,如图2所示。DRX duration timer (drx-on Duration Timer): The time when the UE periodically wakes up to monitor the control channel, as shown in Figure 2.
短DRX周期定时器(Short DRX cycle Timer):为了更好的配合数据业务到达的特点,蜂窝网络通信系统支持配置两种DRX cycle:长周期(long cycle)和短周期(short cycle)。两种cycle的on duration timer相同,但sleep的时间不一样。在short cycle中,sleep时间相对更短,UE可以更快地再次监听控制信道。Long cycle是必须配置的,并且是DRX过程的初始状态;short cycle是可选的。short DRX cycle timer设置了采用short cycle持续的时间。Short cycle timer超时后,UE将使用Long cycle。Short DRX cycle Timer: In order to better match the characteristics of data service arrival, the cellular network communication system supports the configuration of two DRX cycles: long cycle and short cycle. The on duration timer of the two cycles is the same, but the sleep time is different. In the short cycle, the sleep time is relatively shorter, and the UE can monitor the control channel again faster. Long cycle is mandatory and is the initial state of the DRX process; short cycle is optional. The short DRX cycle timer sets the duration of the short cycle. After the Short cycle timer times out, the UE will use the Long cycle.
DRX的非激活定时器(drx-Inactivity Timer):配置了DRX后,当UE在允许监听控制信道的时间内(UE监听控制信道的时间(Active Time))收到HARQ初始传输的控制信令时打开该定时器,在该定时器超时之前,UE连续监听控制信道。如果在drx-Inactivity Timer超时前,UE收到HARQ初始传输的控制信令,将终止并重新启动drx-Inactivity Timer。DRX inactivity timer (drx-Inactivity Timer): After DRX is configured, when the UE receives the control signaling of HARQ initial transmission within the time allowed to monitor the control channel (the time the UE monitors the control channel (Active Time)) Turn on this timer, and until the timer expires, the UE continuously monitors the control channel. If the UE receives the control signaling of HARQ initial transmission before the drx-Inactivity Timer times out, it will terminate and restart the drx-Inactivity Timer.
HARQ往返时延(Round-Trip Time,RTT)定时器(HARQ RTT Timer): 分为DRX的HARQ下行往返时延定时器(drx-HARQ-RTT-Timer DL)和DRX的HARQ上行往返时延定时器(drx-HARQ-RTT-Timer UL),目的是使UE有可能在下次重传到来前不监听控制信道,达到更好的节电效果。以下行为例,UE相关进程的物理上行控制信道(Physical Uplink Control Channel,PUCCH)传输之后的第一个符号启动,将打开此定时器。如果对应HARQ进程中的数据在前一次HARQ传输后解码不成功(UE反馈否定响应(Negative-Acknowledgment,NACK)),在drx-HARQ-RTT-Timer DL超时后,UE打开DRX的下行重传定时器(drx-RetransmissionTimer DL)。如果对应HARQ进程中的数据在前一次HARQ传输后解码成功(UE反馈应答(Acknowledgment,ACK)),在drx-HARQ-RTT-Timer DL定时器超时后,UE不启动drx-Retransmission Timer DL。如果当前只有drx-HARQ-RTT-Timer DL运行,UE不监听控制信道。HARQ round-trip delay (Round-Trip Time, RTT) timer (HARQ RTT Timer): divided into DRX's HARQ downlink round-trip delay timer (drx-HARQ-RTT-Timer DL) and DRX's HARQ uplink round-trip delay timer The purpose is to make it possible for the UE not to monitor the control channel before the next retransmission, so as to achieve better power saving effect. In the following example, the first symbol after the physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission of the UE-related process is started, and this timer will be turned on. If the data in the corresponding HARQ process is not successfully decoded after the previous HARQ transmission (the UE feeds back a negative response (Negative-Acknowledgment, NACK)), after the drx-HARQ-RTT-Timer DL times out, the UE turns on the downlink retransmission timing of DRX timer (drx-RetransmissionTimer DL). If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (UE feedback response (Acknowledgment, ACK)), after the drx-HARQ-RTT-Timer DL timer expires, the UE does not start the drx-Retransmission Timer DL. If only drx-HARQ-RTT-Timer DL is currently running, the UE does not monitor the control channel.
HARQ重传定时器(HARQ retransmission Timer):分为DRX的HARQ上行重传定时器(drx-RetransmissionTimer DL)或者DRX的HARQ下行重传定时器(drx-RetransmissionTimer UL)。以下行为例,在drx-RetransmissionTimer DL运行其间,UE监听控制信令,等待对应HARQ进程的重传调度。HARQ retransmission timer (HARQ retransmission Timer): divided into the HARQ uplink retransmission timer (drx-RetransmissionTimer DL) of DRX or the HARQ downlink retransmission timer (drx-RetransmissionTimer UL) of DRX. In the following example, during the drx-RetransmissionTimer DL operation, the UE monitors the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.
通过上述过程可以看出,在On duration Timer、HARQ retransmission Timer和非激活定时器(Inactivity Timer)中,有任何一个定时器正在运行,UE都将监听控制信道。UE监听控制信道的时间又称为激活时间(Active Time)。Active Time除了受DRX定时器(DRX timer)的影响外还有其它因素影响,如UE的Active Time包括如下时间:drx-onDuration Timer或者drx-Inactivity Timer或者drx-Retransmission Timer DL或者drx-Retransmission Timer UL或者随机接入竞争解决定时器(ra-Contention ResolutionTimer)运行的时间。It can be seen from the above process that, in the On duration Timer, HARQ retransmission Timer and Inactivity Timer, if any timer is running, the UE will monitor the control channel.

或者,第一终端从生成指示第二终端发送CSI报告的第二请求的时刻开始,并经过目标时间段,进入直通链路的DRX或DTX激活状态,以及将直通链路的长DRX周期变更为短DRX周期;或者,将直通链路的长DTX周期变更为短DTX周期,等待接收CSI报告,从而进一步保证终端可以及时接收对端发送的CSI报告,进而保证信息的可靠传输,降低传输性能的损失。Or, the first terminal starts from the moment of generating the second request instructing the second terminal to send the CSI report, and after the target time period passes, enters the DRX or DTX activation state of the through link, and changes the long DRX cycle of the through link to Short DRX cycle; or, change the long DTX cycle of the direct link to a short DTX cycle, and wait for the CSI report to be received, so as to further ensure that the terminal can receive the CSI report sent by the peer end in time, thereby ensuring reliable information transmission and reducing transmission performance. loss.
可选地,上述终端执行在目标时间段内进入直通链路的非连续接收DRX或非连续发送DTX激活状态的步骤,也可以在判断当前的DRX/DTX周期是否满足CSI报告的最大时延需求后再确定是否执行。具体的:Optionally, the above-mentioned terminal performs the step of entering the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link within the target time period, and may also judge whether the current DRX/DTX cycle meets the maximum delay requirement of the CSI report. Then determine whether to execute. specific:

例如:当前DRX/DTX周期中,最近的激活时间无法满足CSI报告的时延需求(即CSI报告的时延要求之前,当前DRX/DTX一直处于睡眠状态),则终端执行在目标时间段内进入直通链路的非连续接收DRX或非连续发送DTX激活状态的步骤,以保证终端可以及时发送CSI报告或等待接收对端发送的CSI报告,进而保证信息的可靠传输,降低传输性能的损失。并在通过在判断当前DRX或DTX的周期不满足CSI报告的最大时延要求的情况下,还可以在一定程度上降低耗电。For example: in the current DRX/DTX cycle, if the latest activation time cannot meet the delay requirement of CSI report (that is, before the delay requirement of CSI report, the current DRX/DTX is always in sleep state), then the terminal executes the entry within the target time period. The step of discontinuous reception of DRX or discontinuous transmission of DTX active state of the direct link ensures that the terminal can send the CSI report in time or wait to receive the CSI report sent by the opposite terminal, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance. And by judging that the current DRX or DTX cycle does not meet the maximum delay requirement of the CSI report, power consumption can also be reduced to a certain extent.
