Description

非连续接收的通信方法、装置、通信设备和通信***
本申请要求于2018年4月4日提交中国国家知识产权局、申请号为201810301051.6、申请名称为“非连续接收的通信方法、装置、通信设备和通信***”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信领域，尤其涉及非连续接收的通信方法、装置、通信设备和通信***。
背景技术
无线通信***可以提供诸如语音、视频、分组数据、消息传送、广播等等各种类型的通信内容。
无线通信***可以采用非连续接收(discontinuous reception，DRX)功能来节省终端设备空闲模式或连接模式下的功率使用。DRX是指终端设备仅在唤醒(awake)周期，有时也称之为激活时间(active time)进入唤醒状态，例如打开接收机以接收下行数据和信令，而在其他时间进入休眠(sleep)状态，例如关闭接收机停止接收下行数据和信令。
随着技术的演进，无线通信***中逐步引入了抢占、免授权(grant free)调度，混合自动重传请求(hybrid automatic repeat request，HARQ)等技术，这些技术如何与DRX功能相配合，是一个需要解决的问题。
发明内容
本发明实施例提供了一种非连续接收的通信方法、装置、通信设备和通信***，可以减少DRX模式下终端设备在HARQ重传中激活时间，节省功耗。本发明实施例还提供了一种非连续接收的通信方法、装置、通信设备和通信***，使得DRX模式的终端设备在发送数据前能及时更新可用的资源，减少数据发送的资源冲突，避免对其他终端设备的干扰。
第一方面，提供了一种非连续接收的通信方法，可用于终端设备，包括：
在定时器T11运行期间接收到网络设备发送的指示信息，其中，所述指示信息包括终端设备的数据初传或数据重传的HARQ反馈信息；
停止所述定时器T11。
其中，定时器T11是在所述数据初传或所述数据重传之后启动的，用于监听物理下行控制信道PDCCH。
在上述方法中，终端设备接收到HARQ反馈信息即停止定时器T11，允许进休眠状态，也就是没有其他满足激活时间的条件成立时，可以进入休眠状态，缩短了终端设备在DRX模式下的激活时间，节省了功耗。
结合第一方面，在第一方面的第一种可能的实现方式中，该方法还可以包括：所述定时器T11停止后，如果当前不是激活时间，确定进入休眠状态。
结合第一方面以及第一方面的第一种可能的实现方式中，在第一方面的第二种可能的实现方式中，可以根据指示信息或者是否分配免授权调度资源确定是否停止定时器T11。
例如，根据指示信息确定不需要继续等待上行授权，也就是指示信息为肯定应答，或者指示信息为肯定应答且没有其他数据需要传输，确定可以停止定时器T11。
又例如，确定已分配免授权调度资源，则可以停止定时器T11。
这种方式下，终端设备根据指示信息一旦确定需要重传或对其他数据初传，可以利用已分配的免调度资源传输，无需等待上行授权。这种方式不影响正常调度场景，终端设备仍可以在drx-RetransmissionTimerUL等待接收上行授权，避免网络设备在此时间段发送上行授权失败，而在其他激活时间重发。
基于第一方面或第一方面各可能的实现方式，该方法还可以包括：

上述方法，在DRX模式的终端设备的上行传输资源被抢占时，可以使得终端设备及时接收资源更新信息，确定可用于发送数据的资源，避免了不同业务或不同终端设备数据传输时的资源占用冲突。
结合第二方面，在第二方面的第一种可能的实现方式中，所述在第二时间段接收资源更新信息包括：
在所述第二时间段起始时刻t3启动时长为m的定时器T21，所述时长m满足m＝t4-t3；
接收所述资源更新信息。
例如，定时器T21的最大时长M以及第二时间段的结束时刻t4的位置可以由网络设备指示给终端设备或者由***定义。终端设备可以根据第二时间段的结束时刻t4的位置确定出第二时间段的结束时刻t4，则定时器T21的时长m为M和t4-t1之中的最小值。
又例如，定时器T21的最大时长M以及第二时间段的起始时刻t3的位置可以由网络设备指示给终端设备，或者由***定义。终端设备可以根据第二时间段的起始时刻t3的位置确定出第二时间段的起始时刻t3，则定时器T21的时长m为M和t2-t3之中的最小值。
通过定时器控制终端设备在第二时间段接收资源更新信息，实现上比较简单。
结合第二方面或第二方面的第一种可能的实现方式，在第二方面的第二种可能的实现方式中，还包括：

如果没有其他满足激活时间的条件成立，则可以确定进入休眠状态。
基于上述第二方面或第二方面各可能的实现方式，还包括：
如果确定有可用资源发送数据，则在数据发送时机到来时，在这些资源发送数据。
由于资源更新及时，在确定可用的资源上发送数据，也避免了对其他终端设备数据传输的干扰。

具体实施方式
为便于理解下面对本申请中涉及到的一些名词做些说明。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信***，例如但不限于，窄带物联网***(Narrow Band-Internet of Things，NB-IoT)、全球移动通信(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、未来的第五代(5th Generation，5G)***或新一代无线接入技术(new radio access technology，NR)等。
为便于理解本申请实施例，首先以图1中示出的通信***为例详细说明适用于本 申请实施例的通信***。图1示出了适用于本申请实施例的通信方法的通信***的示意图。如图1所示，该通信***100可包括多个通信设备，通信设备可以是网络设备，也可以是终端设备。以图1为例，通信***100包括网络设备102和终端设备104，网络设备102可与终端设备104通信。可选地，该通信***100还可包括更多的网络设备和/或更多的终端设备，本申请对此不做限定。每个网络设备102同时支持针对多个终端设备104的通信，例如，网络设备102可以在下行链路信道和上行链路信道上与终端设备104进行通信。其中，下行链路可以是从网络设备102到终端设备104的传输，此时网络设备102可以是发送端设备，终端设备104可以是接收端设备；上行链路可以是从终端设备到网络设备102的传输，此时，网络设备102可以是接收端设备，终端设备104可以是发送端设备。
其中，网络设备可以是任意一种具有无线收发功能的通信设备，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)***中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，***中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的 无线终端等等。本申请的实施例对应用场景不做限定。
在通信***100中，网络设备102可以与多个终端设备(例如包括图中所示的终端设备104)通信。终端设备104也可以与多个网络设备(例如包括图中所示的网络设备102)通信。图1中所示的网络设备102与终端设备104通信的场景仅为本申请所提供的通信方法所适用的一种可能的场景，本申请所提供的通信方法还可适用于更多的场景，例如，多点协作(Coordination Multiple Point，CoMP)传输场景、设备到设备(device to device，D2D)通信场景等，图1中仅为便于理解而示例，并未予以画出。
需要说明的是，本申请中，名词“网络”和“***”经常交替使用，“装置”和“设备”也经常交替使用，但本领域的技术人员可以理解其含义。“通信装置”可以是芯片(如基带芯片，或者数据信号处理芯片，或者通用芯片等等)，终端，基站，或者其他网络设备。
如图2所示，为终端设备104处于DRX状态通信的一个示例。其中，开启期间(On Duration)表示终端设备104监听控制信道时间段。在该期间内终端设备开启射频通道，连续监听控制信道，例如，接收下行指配消息，或者下行反馈信息等。终端设备104监听控制信道的时间段也可以称之为激活时间(active time)，终端设备为唤醒(awake)状态，如图2中t20至t23这段时间，以及t24至t25这段时间。其中，控制信道可以是物理下行控制信道(physical downlink control channel，PDCCH)等。激活时间之外其他时间，终端设备104处于休眠(sleep)状态，其射频通道被关闭，不监听控制信道，以达到省电的目的，有时候也称为关闭期间(Off Duration)或休眠时间，如图2中t23至t24这段时间，以及t20之前的一段时间。开启期间一般是按照DRX周期出现，DRX周期又分为长周期(long cycle)和短周期(short cycle)，短周期配置下终端设备104唤醒的次数相比于长周期配置下要频繁。
为了实现DRX功能，***中定义了多种定时器进行激活时间和休眠状态的控制，如：
1)DRX开启期间定时器(drx-onDurationTimer)：
用于指示每个DRX周期开始时的一段持续时间。该定时器在每个DRX周期开始时开启，如图2中t20，t24所示，分别为DRX周期的开始。如果同时为终端设备配置了长周期和短周期，其drx-onDurationTimer的时长是相同的。这段持续时间为激活时间，终端设备为唤醒状态，需要监听控制信道。
2)DRX活动定时器(drx-InactivityTimer)：
用于指示终端设备从控制信道，如PDCCH上接收到媒体接入控制(media access control，MAC)实体上行或下行数据初传的指示的时机后的持续时间。定时器在终端设备每次接收到数据初传的PDCCH指示后开启，如图2中t21，t22所示。如果定时器超时前，终端设备接收到下一个数据初传的PDCCH指示，将停止并重启该定时器，如图2中t22所示。这段持续时间为激活时间，终端设备为唤醒状态，需要监听控制信道。
drx-InactivityTimer超时后，终端设备可以进入DRX周期中的休眠状态，直到下一周期。
为了提供可靠传输，无线通信***还引入了HARQ技术。接收端设备向发送端设备反馈数据传输成功与否，发送端设备根据反馈信息确定是否需要重传，接收端设备将已接收到的数据初传和重传内容合并译码，提高译码的成功率，从而提高数据传输的成功率。
结合上行HARQ过程，***中还为DRX定义了如下定时器：
3)DRX上行HARQ往返时间定时器(drx-HARQ-RTT-TimerUL)：MAC实体预期接收到上行HARQ重传的授权之前的最短持续时间。也可以认为UL HARQ重传的授权最早在多少个子帧(subframe)或时隙(slot)后出现。每个上行HARQ进程对应一个drx-HARQ-RTT-TimerUL。如图3所示，t330以及t350处进行数据初传或重传后，启动drx-HARQ-RTT-TimerUL。
4)DRX上行重传定时器(drx-RetransmissionTimerUL)：等待接收上行重传的授权(grant)的最长持续时间。每个上行HARQ进程对应一个drx-RetransmissionTimerUL。该定时器在drx-HARQ-RTT-TimerUL结束后启动，同时终端设备在drx-RetransmissionTimerUL运行期间是处于激活时间的，可以用于接收上行授权。如图3所示，t331以及t352处，drx-HARQ-RTT-TimerUL超时，drx-RetransmissionTimerUL启动，并且在终端设备接收到上行授权时停止该定时器。
无线通信***中，DRX状态的控制比较复杂，除了上述定时器外，还可以包括其他定时器，如：DRX下行HARQ往返时间定时器(drx-HARQ-RTT-TimerDL)，DRX下行重传定时器(drx-RetransmissionTimerDL)，随机接入竞争解决定时器(ra-ContentionResolutionTimer)等等。如前述，在一个DRX周期内，包括激活时间和休眠时间，其中，激活时间可以包括以下任一时间，也可以是以下任一条件成立，终端设备处于激活时间：
1)以下定时器运行期间：drx-onDurationTimer，或，drx-InactivityTimer，或，drx-RetransmissionTimerDL，或，drx-RetransmissionTimerUL，或，ra-ContentionResolutionTimer；
2)在上行控制信道，例如PUCCH，发送调度请求，请求数据初传的上行传输资源，并且处于挂起(pending)状态时。这里挂起是指发出该调度请求后还没有接收到对上行传输资源的分配；
3)针对不是MAC实体选择的前导(preamble)的随机接入场景，在成功接收到随机接入响应(random access response)后，还未接收到数据初传的PDCCH指示。
需要说明的是，随着技术的演进，场景的更新，DRX状态下激活时间还可能包括更多其他时间，本发明实施例并不以此为限制。
在正常调度过程中，终端设备每次发送上行数据前，都要接收网络设备的上行资源的授权，如，数据初传的上行资源授权，数据重传的上行授权等，网络设备可以通过PDCCH上的物理层信令，如下行控制信息(downlink control information，DCI)发送上行授权。这种方式不适应短时延业务的需求。
需要说明的是，本申请各实施例中所述的上行资源或下行资源均可以包括以下一项或多项：时域资源、频域资源、HARQ进程、调制编码方案(modulation code scheme，MCS)等。
其中，时域资源可以包括子帧，时隙、周期、符号等中的一项或多项；
频域资源可以包括子载波、带宽、频率等中的一项或多项。
本申请各实施例中所述的定时器的时长或时间段可以包括一个或多个时隙，或，一个或多个子帧，或一个或多个符号，或若干毫秒等。时间或时刻的单位可以是时隙(slot)，或子帧(subframe)，或帧(frame)，或符号，或毫秒(ms)等。这些单位是可以相互换算的，例如在NR***中，1个帧包括10个子帧，每个子帧1ms，每个slot在正常循环前缀(normal cyclic prefix，NCP)下包括的OFDM符号数为14个，在扩展循环前缀(extended cyclic prefix，ECP)下包括的OFDM符号数为固定值12个。每个帧和子帧里包含的slot数目根据子载波间隔的不同而不同，例如，子载波间隔为15kHz时，每个子帧包括时隙数为1，子载波间隔为60kHz时，每个子帧包括的时隙数为4。需要说明的是，此时仅为方便举例，并不以此为限制。每个帧的总长均为10ms，而每个帧包含的时隙数目不同，但是每个时隙的符号数目相同，因此这也就意味着，在不同子载波间隔下，符号的长短是不同。
在新空口技术中，引入了免授权(grant free)调度方式。网络设备为终端设备分配免授权调度资源，可用于短时延业务的传输，终端设备可以直接使用这些资源发送上行数据，不需要等待网络设备对上行资源的授权。例如，网络设备可以通过无线资源控制信令(radio resource control，RRC)信令为终端设备分配免授权调度资源。又例如，网络设备可以通过RRC信令为终端设备分配免授权调度资源，通过DCI指示免授权调度资源的变化。又一种可能的方式中，网络设备也可以通过RRC信令分配静态的资源，DCI分配动态的资源，例如通过RRC信令为终端设备分配时域资源，通过DCI指示频域资源等。需要说明的是，此处均为举例说明，并不限于此。这种方式下，终端设备不需要在每次发送数据前等待接收上行授权，减少了数据发送的时间。
图3为DRX状态下进行上行HARQ重传过程的一个示例。
310：终端设备104向网络设备102发送调度请求，请求上行资源用于数据的传输。
如图所示t310处终端设备104向网络设备发送调度请求。
320：终端设备104接收网络设备102的上行授权，该上行授权用于为终端设备104分配上行资源。
如图所示t320处，网络设备102向终端设备104发送上行授权，处于激活时间的终端设备104接收到网络设备102的上行授权。
其中，上行授权属于下行控制信息DCI中的一种，可以包括用于指示上行资源的信息。
指示上行资源的信息可以是指示资源的标识或编号，或者资源范围等。例如，时隙号，子帧号，符号个数，带宽，子载波标识，频率，频点，MCS索引，HARQ进程标识等等。需要说明的是，此处均为举例说明，本申请实施例并不限于此。
上行资源可以是动态调度的资源，通过PDCCH物理层信令在每次发送数据前指示，例如，通过DCI在每次发送数据前指示；也可以是免授权调度的资源，通过RRC信令或者RRC信令和物理层信令配合指示。例如，时域资源通过RRC信令进行指示，如通过RRC信令指示周期；又例如，频域资源可以通过RRC信令或物理层信令，如DCI，指示。又例如，MCS可以通过RRC信令或DCI进行指示。又例如，HARQ进 程标识，可以通过RRC信令进行指示。
330：终端设备104根据步骤320所指示的上行资源进行数据的初传，并启动定时器drx-HARQ-RTT-TimerUL。
定时器drx-HARQ-RTT-TimerUL运行期间，如t330至t331期间，如果不是激活时间，则终端设备可以休眠，不监听PDCCH。
定时器drx-HARQ-RTT-TimerUL超时后，终端设备104启动drx-RetransmissionTimerUL，且监听PDCCH，如图3所示t331处。
340：终端设备104接收网络设备102的HARQ反馈信息。
网络设备102向终端设备104发送HARQ反馈信息，用于对终端设备104发送的数据进行反馈。如果不能正确接收到终端设备104发送的上行数据，如，未接收到该数据，或者接收到但不能成功译码等，网络设备102发送否定应答NACK，使终端设备104获知需要进行重传；如果接收到且能成功译码终端设备发送的上行数据，网络设备102发送肯定应答ACK，终端设备104可以不必进行重传。
在图3所示例的过程中，网络设备102在t340发送的是对数据初传的否定应答，在t360发送的是对数据重传的肯定应答。需要说明的是，此处仅为举例，并不以此为限制。
在一种可能的实现方式中，网络设备102也可以向终端设备104发送上行授权，如340’所示，用于指示用于数据重传的上行资源。终端设备104接收到该信息即可获知需要进行重传。在t340’处终端设备104停定时器drx-RetransmissionTimerUL，如果此时没有其他满足激活时间的条件成立，则终端设备104可以进入休眠状态，直到激活时间出现，如图3中t341处。
350：终端设备104进行数据重传，并启动定时器drx-HARQ-RTT-TimerUL。
对于采用免授权调度的终端设备，如果已经分配到免授权调度资源，则可以在免授权调度资源中确定用于重传的上行资源，并进行重传；
对于正常调度的终端设备，可以根据步骤340’所指示的上行资源在t350处进行数据的重传。
可以理解的是，数据的初传和重传的内容可以不相同，也可以相同。例如初传是数据的冗余版本0，重传是数据的冗余版本2，又例如初传是数据的冗余版本0，第一次重传是数据的冗余版本3，第二次重传是数据的冗余版本0。每个冗余版本都是数据的信息比特及其冗余比特组成的数据块的一部分，例如，从该网络设备102可以将接收到多个冗余版本合并译码得到该数据，或者说是得到该数据的信息比特。
定时器drx-HARQ-RTT-TimerUL运行期间，如t350至t352期间，如果不是激活时间，则终端设备可以休眠，不监听PDCCH。
定时器drx-HARQ-RTT-TimerUL超时后，终端设备104启动drx-RetransmissionTimerUL，且监听PDCCH，如图3所示t352处。
360：终端设备104接收网络设备102的HARQ反馈信息。
网络设备102向终端设备104发送HARQ反馈信息可参见步骤340中描述，此处不再赘述。如图3所示终端设备104在t360处收到肯定应答，终端设备104可以不必进行重传，待定时器drx-RetransmissionTimerUL超时后，如果没有其他满足激活时间 的条件成立，则终端设备104可以进入休眠状态，直到激活时间出现。
可以理解的是，步骤350中数据重传可以不止一次，如果网络设备对数据重传发送否定应答，则终端设备104可以继续对数据进行重传，也就是重复步骤340和350，直到收到肯定应答如步骤360，或重传定时器超时才结束。
如果终端设备104已分配到免授权调度资源，则可以在接收到HARQ反馈信息后确定是否需要在在免授权调度资源上数据的重传或另一数据的初传，不需要继续等待上行授权。而图3所示例的过程中，终端设备104接收到HARQ反馈信息后仍处于drx-RetransmissionTimerUL运行的激活时间，即使没有其他满足激活时间的条件成立，终端设备104也不能进入休眠状态。如果能在t340或t360处接收到HARQ反馈信息后停止定时器drx-RetransmissionTimerUL，在没有其他满足激活时间的条件成立时，终端设备104可以进入休眠状态，进一步节省功耗。如图4所示为免授权调度场景下，对图3所示例过程的改进。免授权调度场景下，网络设备可以通过RRC信令或RRC信令结合DCI指示用于多次数据传输的资源，而不需要在每次数据传输前通过PDCCH上的DCI指示该次数据传输的资源。其中步骤410至步骤430，450与图3对应的步骤310至步骤330以及350相同，与图3所不同的是，步骤440和步骤460中，接收到HARQ反馈信息后，停止定时器drx-RetransmissionTimerUL。从而终端设备104可以进入休眠状态。可以理解的是，步骤450中重传可以不止一次，如果网络设备对重传发送否定应答，则终端设备104可以继续对数据进行重传，也就是重复步骤440和450，直到收到肯定应答如步骤460，或重传定时器超时才结束。
图5为本发明一实施例提供的非连续接收的通信方法的示意性流程图。如图所示，包括：
540：终端设备104在激活时间接收到网络设备102发送的指示信息，其中，所述指示信息包括终端设备的数据初传或数据重传的HARQ反馈信息。
其中，激活时间可以是终端设备104初传或重传之后的时间，可以通过启动定时器T11来控制，从而终端设备104在定时器T11运行期间接收到网络设备102发送的指示信息。
指示信息可以是下行反馈信息DFI，包括了对终端设备104对数据初传或重传的HARQ反馈信息，如：肯定应答或否定应答。其中，指示信息还可以包括：载波指示字段(carrier indicator field，CIF)，或，发送功率控制(transmit power control，TPC)，或，CIF和TPC等。
在一种可能的实现方式中，指示信息可以是网络设备102对上述信息使用小区网络临时标识(cell radio network temporary identifier，C-RNTI)加扰后得到的。终端设备104接收到指示信息后，可以进行解扰等等上述信息。
终端设备104对数据的初传或重传既可以是通过正常调度，在正常调度所分配的资源传输，也可以在免授权调度所分配的资源上传输。
550：终端设备104停止定时器T11。
终端设备104停止定时器T11，如果当前不是激活时间，终端设备104可以进入休眠状态。
如果指示信息指示肯定应答，终端设备104无需进行重传，并且终端设备104也没有其他数据需要传输，可以提前结束激活时间，无需等待定时器T11超时。
如果指示信息为否定应答，或者指示信息虽然为否定应答，但是终端设备104仍有其他数据需要传输：
对于正常调度，如果终端设备104此时没有接收到上行授权，则可以等待下个激活时间到来时监听PDCCH信道，接收网络设备发送的上行授权。
对于免授权调度，终端设备104可以通过免授权调度资源进行重传，所以不需要继续等待上行授权。
可见，上述方法在HARQ传输时，接收到数据的HARQ反馈信息即停止定时器，允许进入休眠状态，可以减少终端设备处于激活状态的时长，节省功耗。
可选地，终端设备104也可以根据指示信息或者是否分配免授权调度资源确定是否停止定时器T11。
一种可能的方式为，终端设备104根据指示信息确定不需要继续等待上行授权，也就是指示信息为肯定应答，或者指示信息为肯定应答且没有其他数据需要传输，终端设备可以停止定时器T11。
又一种可能的方式为，终端设备104如果已分配免授权调度资源，则可以停止定时器T11。这种方式下，终端设备根据指示信息一旦确定需要重传或对其他数据初传，可以利用已分配的免调度资源传输，无需等待上行授权。这种方式不影响正常调度场景，终端设备仍可以在drx-RetransmissionTimerUL等待接收上行授权，避免网络设备在此时间段发送上行授权失败，而在其他激活时间重发。
可选地，对于免授权调度场景，该通信方法还可以包括：
560：终端设备104可以根据指示信息确定是否在第一免授权调度资源上对所述数据进行重传。
若指示信息包括否定应答，终端设备104确定需要对数据进行重传，如果终端设备104已被分配免授权调度资源，则可以从免授权调度资源中确定第一免调度资源用于对数据进行重传。
若指示信息包括肯定应答，终端设备104确定不需要对数据进重传。进一步地，终端设备104确定是否有其他数据需要传输。如果没有其他数据需要传输，终端设备104可以根据当前是否激活时间确定是否需要进入休眠状态；如果有数据需要传输，且终端设备104已被分配免授权调度资源，则可以从免授权调度资源中选择第一免调度资源用于新的数据的传输。
可选地，步骤540之前还可以包括：
530：终端设备104启动定时器T11，用于监听PDCCH。
其中，一种可能的实现方式中，定时器T11可以是drx-RetransmissionTimerUL，该定时器可以在drx-HARQ-RTT-TimerUL超时后启动，如图4中步骤430或450。当然定时器T11也可以是其他定时器，定时器T11运行期间，也就是处于激活时间，终端设备104可以监听物理下行控制信道PDCCH。
可选地，步骤530之前还可以包括对数据进行初传或重传，并且在初传或重传后启动定时器drx-HARQ-RTT-TimerUL。
可选地，步骤530之前还可以包括如图4中步骤410至420，获取数据初传或重传的上行授权。
通过本实施例的方法，终端设备接收到所传输数据的反馈信息后，即允许尽早进入休眠状态，而不需要继续监听PDCCH，等待上行授权，从而可以减少终端设备处于激活状态的时长，进一步节省功耗。
在非连续接收模式下，终端设备在数据发送时机到来前，可能处于休眠状态。如果网络设备将分配给该数据的资源进行再分配，终端设备不及时更新资源信息，可能造成数据发送失败。可以理解的是，网络设备对资源的再分配既可以是将该资源分配给其他终端设备，也可以是将改资源分配给同一终端设备的其他高优先级业务。本发明实施例并不以此为限制。
图6为本发明另一实施例提供的非连续接收的通信方法的示意性流程图。如图所示，包括：
610：网络设备102在第一时间段向终端设备104发送上行授权信息。
网络设备102确定终端设备104在第一时间段处于激活时间，向终端设备104发送上行授权信息，该上行授权信息用于分配上行传输资源。例如，网络设备102为终端设备104分配资源0,1,2和3。
终端设备在DRX状态下的多个定时器可以由网络设备配置，故网络设备可以根据终端设备处于激活时间的条件以及相应的定时器时长和启动时间确定终端设备是否处于激活时间，从而使得网络设备和终端设备在DRX状态下收发信息和激活时间是匹配的。
终端设备104在第一时间段接收到上行授权信息。
其中，第一时间段可以是终端设备104的激活时间，终端设备104的激活时间可以参考前述，此处不再赘述。第一时间段的结束时刻为t1。
一种可能的方式为终端设备104接收到上行授权，即停相应定时器，如drx-RetransmissionTimerUL，如图3所示t340所示，则第一时间段的结束时刻t1为终端设备104接收到上行授权的时刻。
又一种可能的方式为，终端设备104接收到上行授权，但仍处于激活时间，等定时器超时后，终端设备可以进入休眠状态，如图3所示t321所示，则第一时间段的结束时刻t1为激活时间结束的时刻。
终端设备104根据上行授权信息可以确定上行传输资源的结束时刻为t2，其中上行传输资源的结束时刻不早于第一时间段的结束时刻，t2≥t1。
例如，子载波间隔为30kHz，一个子帧包括2个时隙，第一时间段包括3个时隙，子帧0的时隙0～1，子帧1的时隙0，结束时刻t1为子帧1的时隙0，上行传输资源分配了14个符号，在子帧2的时隙1上，也就是上行传输资源的结束时刻为子帧2的时隙1，则t2和t1之间的间隔为3个时隙。需要说明的是此处为方便举例，以第一时间段和上行传输资源是在同一帧为例，第一时间段和上行传输资源也可以在不同帧，又例如，子载波间隔为120kHz，一个子帧包括8个时隙，第一时间段包括12个时隙，子帧0的时隙0～7，子帧1的时隙0～3，结束时刻t1为子帧1的时隙3，上行传输资源 分配了28个符号，在下一帧的子帧1的时隙0～1上，也就是上行传输资源的结束时刻为下一帧的子帧1的时隙1上，则t2和t1之间的间隔为78个时隙。上述均为举例说明，本申请实施例并不以此为限制。
620：网络设备102向终端设备104发送资源更新信息，所述资源更新信息用于指示所述上行传输资源中部分或全部资源的可用状态。
网络设备102可以按周期向终端设备104发送资源更新信息；
网络设备102也可以确定分配给终端设备104的上行传输资源中部分或全部资源的可用状态发生改变，向终端设备104发送资源更新信息。
其中，可用状态可以是下述中的一个，被抢占、无效或者可用。
网络设备发送资源更新信息的时机可以是确定状态改变后，在终端设备数据发送时机前或数据发送中的激活时间发送。
630：终端设备在第二时间段接收资源更新信息。
其中第二时间段的起始时刻为t3，结束时刻为t4，t3≥t1且t4≤t2。
第二时间段的起始时刻t3不早于第一时间段的结束时刻t1，且第二时间段的结束时刻t2不晚于第一时间段的结束时刻t4。
例如，仍以步骤610中所示例的为例，第一时间段的结束时刻t1为子帧1的时隙0，上行传输资源的结束时刻为子帧2的时隙1，则第二时间段的起始时刻t3不早于子帧1的时隙0，结束时刻t4不晚于子帧2的时隙1。
如图7中A)所示，为第二时间段的一个示例，其中第二时间段的结束时刻t4和上行传输资源的结束时刻t2相同，在上行传输资源结束时刻t2之前的3个时隙为第二时间段。第二时间段的结束时刻t4与上行传输资源的结束时刻t2的间隔为x，从而第二时间段的时长为3个时隙，第二时间段的结束时刻t4与上行资源的结束时刻t2的间隔为0。
如图7中B)所示，为第二时间段的又一个示例，其中第二时间段的起始时刻t3在第一时间段结束时刻t1之后2个时隙，时长m为2个时隙。
一种可能的实现方式中，在第二时间段起始时刻t3启动时长为m的定时器T21，该时长m满足m＝t4-t3，使终端设备处于激活时间，可以监听PDCCH，接收资源更新信息。终端设备的激活时间也可以包括定时器T21运行期间。需要说明的是，m的时间单位可以是本文中所例举的时间段或定时器的时间单位中任一种，如，时隙，毫秒，符号等等。
一种可能的实现方式中，定时器T21的最大时长M以及第二时间段的结束时刻t4的位置可以由网络设备指示给终端设备，或者由***定义。终端设备可以根据第二时间段的结束时刻t4的位置确定出第二时间段的结束时刻t4，则定时器T21的时长m为M和t4-t1之中的最小值，其中，第二时间段的结束时刻t4的位置可以是结束时刻t4的绝对位置，例如第i子帧第j时隙；第二时间段的结束时刻t4的位置也可以是结束时刻t4与上行传输资源的结束时刻t2之间的间隔，也就是相对于t2提前多少时间单位，例如，提前2个时隙等。
又一种可能的实现方式中，定时器T21的最大时长M以及第二时间段的起始时刻t3的位置可以由网络设备指示给终端设备，或者由***定义。终端设备可以根据第二 时间段的起始时刻t3的位置确定出第二时间段的起始时刻t3，则定时器T21的时长m为M和t2-t3之中的最小值，其中，第二时间段的起始时刻t3的位置可以是起始时刻t3的绝对位置，例如第i子帧第j时隙；第二时间段的起始时刻t3的位置也可以是起始时刻t3与第一时间段的结束时刻t1之间的间隔，也就是相对于t1推后多少时间单位，例如，推后14个符号等。
需要说明的是，上述均为举例，本申请实施例并不限于此。
进一步地，如果在定时器T21运行期间接收到资源更新信息，则停止定时器T21。终端设备如果没有其他满足激活时间的条件成立，终端设备可以进入休眠状态。
640：终端设备根据资源更新信息确定所述上行传输资源中可用于发送数据的资源。
终端设备可以根据资源更新信息中部分或全部资源的可用状态确定已分配的上行传输资源中可用于发送数据的资源。例如，网络设备确定需要将步骤610中分配的资源1和3分配给其他终端设备，则网络设备在620中向终端设备发送资源更新信息。一种可能的实现方式中，资源更新信息中指示资源0～3的可用状态，其中资源1和3的可用状态为被抢占，资源0和2的可用状态为可用，终端设备可以根据资源信息更新每一资源的可用状态，确定状态为可用的资源0和2用于发送数据；又一种可能的实现方式中，资源0和2的可用状态因为没有发生变化，资源更新信息中指示可用状态发生变化的资源1和3，其可用状态为被抢占，终端设备可以根据该信息确定资源0和2可用于发送数据；又一种可能的实现方式中，资源更新信息中指示可用的资源0和2，不包括被抢占的资源1和3，终端设备根据该信息确定资源0和2为可用于发送数据的资源。需要说明的是，此处仅为举例，本发明实施例不限于此。
可选地，还包括：
650：网络设备在上行传输资源中可用的资源上接收所述终端设备的数据。
终端设备在步骤640中如果确定有可用资源发送数据，则在数据发送时机到来时，在这些资源发送数据。
网络设备可在可用资源上接收到终端设备发送的数据。
需要说明的是，本发明实施例是从设备交互的角度进行描述的，对于终端设备和网络设备，可以分别执行各自的方法步骤完成本发明实施例提供的方法。
通过本发明实施例提供的方法，在DRX模式的终端设备的上行传输资源被抢占时，可以使得终端设备及时接收资源更新信息，确定可用于发送数据的资源，避免了不同业务或不同终端设备数据传输时的资源占用冲突，也避免了对其他终端设备数据传输的干扰。
图8为本发明另一实施例提供的非连续接收的通信方法的示意性流程图。如图所示，包括：
810：终端设备104启动定时器T31，用于监听物理下行控制信道PDCCH；
终端设备104启动定时器T31，处于激活时间，可以监听PDCCH，接收资源更新信息。终端设备的激活时间也可以包括定时器T31运行期间。
一种可能的实现方式中，定时器T31可以是定时器drx-RetransmissionTimerUL，当然，定时器T31也可以是控制终端设备激活时间的定时器。
820：网络设备102在第一时间段向终端设备104发送上行授权信息。
网络设备102确定终端设备104处于激活时间，向终端设备104发送上行授权信息，上行授权信息用于分配上行传输资源；
终端设备104在定时器T31运行期间接收到上行授权信息。终端设备不停止定时器T31，继续处于激活时间。
例如，定时器T31为drx-RetransmissionTimerUL，终端设备接收到上行授权后，通常是要停止为drx-RetransmissionTimerUL，但根据本实施例的方法，终端设备并不停止该定时器，继续处于激活时间。
830：网络设备102向终端设备104发送资源更新信息，所述资源更新信息用于指示所述上行传输资源中部分或全部资源的可用状态。
网络设备可以按周期向终端设备发送资源更新信息；
网络设备也可以确定分配给终端设备104的上行传输资源中部分或全部资源的可用状态发生改变，向终端设备104发送资源更新信息。
其中，可用状态可以是下述之一：被抢占、无效或者可用。
网络设备发送资源更新信息可参考前述实施例步骤620。
840：终端设备104接收资源更新信息。
850：终端设备根据资源更新信息确定所述上行传输资源中可用于发送数据的资源。
终端设备根据资源更新信息确定所述上行传输资源中可用于发送数据的资源可参见前述方式实施例中步骤640描述，此处不再赘述。
可选地，还包括：
860：终端设备在可用于发送数据的资源中发送数据。
终端设备在步骤850中如果确定有可用资源发送数据，则在数据发送时机到来时，在这些资源发送数据。
可选地，还包括：
870：若定时器T31处于运行期间，则终端设备停止定时器T31。
定时器T31运行期间，若终端设备在步骤850中确定无可用资源发送数据，终端设备可停止定时器T31。
若终端设备在步骤850中确定有可用资源发送数据，终端设备可以在步骤860发送完数据后，停止定时器T31。
停止定时器T31后，若终端设备没有其他满足激活时间的条件成立，则终端设备可以进入休眠状态。
通过本发明实施例提供的方法，在DRX模式的终端设备的上行传输资源被抢占时，可以使得终端设备及时接收资源更新信息，确定可用于发送数据的资源，避免了不同业务或不同终端设备数据传输时的资源占用冲突，也避免了对其他终端设备数据传输的干扰。
