- the base station issues configuration to the UE through RRC signaling configuredGrantConfig.
- the signaling includes rrc-ConfiguredUplinkGrant. If the UE needs to send PUSCH, it can directly send PUSCH according to this configuration without waiting for the base station to issue DCI scheduling. Or activate; this method is also called grant free PUSCH
- the base station first issues the RRC layer signaling configuredGrantConfig (excluding rrc-ConfiguredUplinkGrant), and then the UE needs to receive the DCI issued by the base station to activate the configuration. After the UE is activated, it performs periodic data transmission at fixed resources and fixed times. This method is also called semi-static PUSCH (similar to semi-static PDSCH).
- SRS sounding reference signal
- channel state information channel state information
- SRS is a signal sent by the UE to the base station for measuring channel quality

- SRS and CSI reporting are uplink signals sent by the UE, which are divided into three types: aperiodic/periodic/semi-static (A/P/SP, Aperiodic/Persistent/Semi Persistent):
- the uplink signal is sent based on the trigger of PDCCH issued by the base station, and the trigger is sent once (similar to dynamic PDSCH/PUSCH scheduling);
- P-SRS/P-CSI is sent periodically, that is, the base station is configured with the RRC signaling configuration for SRS/CSI reporting, and the UE sends SRS/CSI reporting according to this configuration period;
- SP-SRS/SP-CSI is also sent periodically, but the base station needs to configure RRC configuration and the base station needs to issue a PDCCH trigger so that the UE can send it periodically according to the configuration; (similar to configured grant type 2/SPS PDSCH).
- CSI-RS is a downlink reference signal sent by the base station, which is received and measured by the UE (the measurement is sent to the base station in the above CSI report); CSI of the UE -RS measurement behavior is also divided into three types: A/P/SP:
- A-CSI-RS based on the PDCCH issued by the base station, tells the UE where to perform measurements, triggering the measurement once (similar to dynamic PDSCH/PUSCH scheduling);
- P-CSI-RS is a periodic measurement, that is, the base station is configured with CSI-RS measurement configuration, and the UE measures the channel according to the configuration period;
- SP-CSI is also measured periodically, but the base station needs to configure the CSI-RS measurement configuration and the base station needs to issue a PDCCH trigger so that the UE can measure periodically according to the configuration; (similar to configured grant type 2/SPS PDSCH).
- Dis-continuous transmission (DTX) mechanism In order to further reduce the power consumption of communication equipment, the communication equipment can be enabled not to send data transmission for a period of time, or the communication equipment can be enabled not to transmit data for a period of time. Send all channels or part of channels. This way of reducing power consumption of communication equipment can be called the DTX mechanism.
- DTX Due to the interactive nature of communication systems, DTX has different interpretations of two or more communication devices communicating.
- DTX can be understood as a non-persistent sending mechanism.
- the receiving device corresponding to the sending device configured with DTX the receiving device at this time can be understood as a non-continuous receiving mechanism in DTX.
- DTX in this application refers to the non-persistent transmission mechanism at the cell level. Since network equipment can communicate with multiple terminal devices in the cell, for convenience of description, DTX at the cell level in this application can also be understood as network equipment.
- DTX mechanism through the DTX mechanism of network equipment, energy saving of network equipment can be achieved.
- the network device can set a transmission pattern to only transmit data in part of the time period within a transmission cycle, and do not send or receive data in other time periods.
- the network device DTX mechanism can be used to reduce the power consumption of the network device.
- the network device DTX mechanism can also be used to aggregate the data to be sent into time period A. Send, so that it can enter the DTX state in time period B to achieve static energy saving of network equipment.
- Dis-continuous reception (DRX) mechanism enables the terminal to detect the physical downlink control channel (PDCCH) only within a specified time period, but this technology only works on some transmission channels and signals.
- the base station cannot completely silence the base station through the DRX configuration of the UE.
- the basic mechanism of DRX is to configure a DRX cycle for the terminal device in the radio resource control (RRC) connected state.
- the DRX cycle consists of "on Duration” and “Opportunity for DRX”: During the "on duration” period, the terminal device detects and receives the physical downlink control channel (PDCCH) ); and during the "DRX opportunity” period, the terminal equipment does not detect the PDCCH to save power consumption.
- PDCH physical downlink control channel
- FIG. 2 is a schematic diagram of the DRX basic model provided by this application.
- the terminal equipment in the RRC connected state periodically enters the activation time period and the deactivation time period.
- the terminal equipment performs PDCCH detection, and when the terminal equipment enters the deactivation time During this period, the terminal equipment no longer detects the PDCCH, that is, the terminal equipment does not need to be in a state of detecting the PDCCH all the time, thereby achieving the purpose of reducing terminal power consumption.
- the base station sends DRX configuration information to the terminal device, so that the terminal device enters the activation mode within a specified time period based on the DRX configuration information, and enters the deactivation mode at the rest of the time to achieve sleep under the DRX mechanism.
- the DRX configuration mainly includes the following parameters:
- Activation timer (on Duration Timer): It can be understood as a continuous number of downlink subframes, indicating the time that the terminal device can maintain after waking up from sleep state. Within this number of consecutive downlink subframes, the terminal device needs to listen to the physical downlink control channel.
- DRX inactivity timer (DRX-Inactivity Timer): It can also be understood as a continuous number of downlink subframes.
- the DRX inactivation timer is started when the terminal device successfully demodulates the first symbol after the reception of the PDCCH that schedules the new transmission (uplink or downlink) of the terminal device, indicating that the corresponding MAC receives a PDCCH indicating a new transmission.
- the length of time to monitor PDCCH is also required. That is to say, it is necessary to continue to monitor the physical downlink control channel during the timing period of the DRX inactivation timer.
- DCI Downlink control information
- PDSCH physical downlink shared channel
- SPS downlink semi-persistent scheduling
- the terminal equipment will start at the starting moment of the first symbol after the end symbol of the physical uplink control channel (PUCCH) that carries the feedback information "ACK/NACK" of the PDSCH transmission.
- PUCCH physical uplink control channel
- RTT round trip time
- DRX–Retransmission Timer uplink DRX retransmission timer
- the terminal equipment is considered to be in the activation time period (Active Time) in any of the following situations; otherwise, it is considered to be in the deactivation time period (Inactive Time): activation time timer, DRX inactivation timer, downlink DRX resumption timer transmission timer and uplink DRX retransmission timer.
- the terminal device when the terminal device sends a scheduling request and the scheduling request is in the "pending" state, and when the terminal device ends based on the non-contention random access process, the terminal device receives a PDCCH indicating a cell wireless network temporary identifier. When a new scrambled transmission is not successfully received, the terminal device is also considered to be in the activation period.
- the terminal equipment during the operation of the activation time timer, DRX inactivation timer, downlink DRX retransmission timer, uplink DRX retransmission timer, and when the terminal device sends a scheduling request and the scheduling request is pending In the "pending" state and when the terminal equipment receives a PDCCH indicating that a new transmission scrambled by a cell wireless network temporary identifier has not been successfully received, the terminal equipment is in the time period for PDCCH detection, and in the remaining time periods, the terminal equipment is in a non-stop state.
- the deactivation period for PDCCH detection is performed to reduce the power consumption of the terminal equipment.
- the deactivation period may also be referred to as the dormancy period under the DRX mechanism.
- This technology only works on some transmission channels and signals, and the base station cannot completely silence the base station through the UE's DRX configuration.
- the base station cannot completely shut down the base station through the UE's DRX configuration. That is to say, the base station will still send some downlink signals when it is inactive.
- the transmission of this part of the signal causes the power consumption of the base station to increase.
- the UE still has to receive this signal when it is inactive.
- Some signals for example, 1) SSB, PRACH, 2) SI/RA/TC/P-RNTI, PS-RNTI scrambled DCI, 3) SPS PDSCH, 4) CG PUSCH, 5) HARQ-ACK for SPS PDSCH, 6) SR/BFR, so the UE will receive the above signal during the DRX inactive Time, so the base station cannot turn off signal transmission during the DRX inactive Time of the UER, otherwise it will affect the UE reception. Therefore, the base station cannot turn off data transmission through the existing DRX configuration of the UE, that is, it cannot achieve sleep on the base station side.
- the inactive Time of UE DRX does not take effect for some transmissions, and the existing UE DRX configuration is configured through RRC signaling.
- the two reconfigurations take a long time and cannot be dynamically adjusted according to the dynamic changes of the service load. Flexibly and dynamically adjust the DRX configuration of UE received data to achieve maximum energy saving.

图1是适用于本申请实施例的通信***1000的架构示意图。如图1所示,该通信***包括无线接
入网100和核心网200,可选地,通信***1000还可以包括互联网300。其中,无线接入网100可以包括至少一个无线接入网设备(如图1中的110a和110b),还可以包括至少一个终端(如图1中的120a-120j)。终端通过无线的方式与无线接入网设备相连,无线接入网设备通过无线或有线方式与核心网连接。核心网设备与无线接入网设备可以是独立的不同的物理设备,也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端和终端之间以及无线接入网设备和无线接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图,该通信***中还可以包括其它网络设备,如还可以包括无线中继设备和无线回传设备,在图1中未画出。
接入网设备也可以称为接入设备,(R)AN能够管理无线资源,为用户设备提供接入服务,完成用户设备数据在用户设备和核心网之间的转发,(R)AN也可以理解为网络中的基站。
示例性地,本申请实施例中的接入网设备可以是用于与用户设备通信的任意一种具有无线收发功能的通信设备。该接入网设备包括但不限于:基站(base station)、演进型基站(evolved NodeB,eNodeB)、发送接收点(transmission reception point,TRP)、第五代(5th generation,5G)移动通信***中的下一代基站(next generation NodeB,gNB)、第六代(6th generation,6G)移动通信***中的下一代基站、未来移动通信***中的基站或WiFi***中的接入节点等;也可以是完成基站部分功能的模块或单元,例如,可以是集中式单元(central unit,CU),也可以是分布式单元(distributed unit,DU)。这里的CU完成基站的无线资源控制协议和分组数据汇聚层协议(packet data convergence protocol,PDCP)的功能,还可以完成业务数据适配协议(service data adaptation protocol,SDAP)的功能;DU完成基站的无线链路控制层和介质访问控制(medium access control,MAC)层的功能,还可以完成部分物理层或全部物理层的功能,有关上述各个协议层的具体描述,可以参考第三代合作伙伴计划(3rd generation partnership project,3GPP)的相关技术规范。无线接入网设备可以是宏基站(如图1中的110a),也可以是微基站或室内站(如图1中的110b),还可以是中继节点或施主节点等。
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括有源天线单元(active antenna unit,AAU)。CU实现gNB的部分功能,DU实现gNB的部分功能。比如,CU负责处理非实时协议和服务,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负责处理物理层协议和实时服务,实现无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层和物理(physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息由CU生成,最终会经过DU的PHY层封装变成PHY层信息,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,也可以认为是由DU发送的,或者,由DU+AAU发送的。可以理解的是,接入网设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外,可以将CU划分为接入网(radio access network,RAN)中的接入网设备,也可以将CU划分为核心网(core network,CN)中的接入网设备,本申请对此不做限定。
本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。为了便于描述,下文以基站作为无线接入网设备的例子进行描述。
终端也可以称为终端设备、UE、移动台、移动终端、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、无线通信设备、用户代理或用户装置等。本申请的实施例中的终端可以是手机(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、增强现实(augmented reality,AR)终端、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、蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,5G网络中的终端或者未来演进网络中的终端等。
终端可以广泛应用于各种场景,例如,设备到设备(device-to-device,D2D)、车物(vehicle to everything,V2X)通信、机器类通信(machine-type communication,MTC)、物联网(internet of things,
IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。
基站和终端可以是固定位置的,也可以是可移动的。基站和终端可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上;还可以部署在飞机、气球和人造卫星上。本申请的实施例对基站和终端的应用场景不做限定。
基站和终端的角色可以是相对的,例如,图1中的直升机或无人机120i可以被配置成移动基站,对于那些通过120i接入到无线接入网100的终端120j来说,终端120i是基站;但对于基站110a来说,120i是终端,即110a与120i之间是通过无线空口协议进行通信的。当然,110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的,此时,相对于110a来说,120i也是基站。因此,基站和终端都可以统一称为通信装置,图1中的110a和110b可以称为具有基站功能的通信装置,图1中的120a-120j可以称为具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信,也可以通过免授权频谱进行通信,也可以同时通过授权频谱和免授权频谱进行通信;可以通过6千兆赫(gigahertz,GHz)以下的频谱进行通信,也可以通过6GHz以上的频谱进行通信,还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。
在本申请的实施例中,基站的功能也可以由基站中的模块(如芯片)来执行,也可以由包含有基站功能的控制子***来执行。这里的包含有基站功能的控制子***可以是智能电网、工业控制、智能交通、智慧城市等上述应用场景中的控制中心。终端的功能也可以由终端中的模块(如芯片或调制解调器)来执行,也可以由包含有终端功能的装置来执行。
可以理解,上述应用于本申请实施例的网络架构仅是一种举例说明,适用本申请实施例的网络架构并不局限于此,任何能够实现上述各个网元的功能的网络架构都适用于本申请实施例。
在未来的通信***,例如6G通信***中,上述网元或设备仍可以使用其在4G或5G通信***中的名称,或者也可以有其它名称,本申请实施例对此不作限定。上述网元或设备的功能可以由一个独立网元完成,也可以由若干个网元共同完成。在实际部署中,核心网中的网元可以部署在相同或者不同的物理设备上。例如作为一种可能的部署,可以将AMF和SMF部署在同一个物理设备上。又例如,5G核心网的网元可以和4G核心网的网元部署在同一物理设备上。本申请实施例对此不作限定。
可以理解,图1只是一种示例,对本申请的保护范围不构成任何限定。本申请实施例提供的通信方法还可以涉及图1中未示出的网元,当然本申请实施例提供的通信方法也可以只包括图1示出的部分网元。
随着第五代(5th generation,5G)通信***的不断发展,使用的频谱越来越宽,配置的发送天线数目越来越多,接入网设备整体消耗功率越来越高。但网络侧的功耗和业务负载并不成正比,每个传输时间间隔(transmission time interval,TTI)上接入网设备功耗都包括很多部分,例如与负载相关的动态功耗部分、与负载无关的静态功耗部分。也就是说,即使负载较轻时,与负载无关的静态部分仍然会导致接入网设备消耗能量。
现有NR协议中,支持给终端设备配置非连续接收(dis-continuous reception,DRX)机制,使能终端设备只在规定时间段进行下行控制信道(physical downlink control channel,PDCCH)检测,但是该技术只对部分传输信道、信号起作用,接入网设备并不能通过UE的DRX配置实现数据传输的关断,无法完全实现接入网侧的休眠。
如何能根据业务负载实现动态关断,降低接入网设备的功耗,已成为目前研究的重点问题。
为便于理解本申请实施例,对本申请中涉及到的术语做简单说明。
1、同步信号/物理广播信号(synchronization signals/PBCH,SSB):包括主同步信号(primary synchronization signals,PSS)、辅同步信号(secondary synchronization signals,SSS)、物理广播信道(physical broadcast channel,PBCH)。其中,PSS/SSS主要用于终端设备下行同步和获取小区标识(identification,ID),下行同步包括时钟同步,无线帧同步,符号同步。其中,PBCH主要用于承载主信息块(master information block,MIB),MIB中包括***帧号(system frame number,SFN),子
载波间隔,调度***信息(system information,SI)的PDCCH配置等信息。
2、物理随机接入信道(physical random access channel,PRACH):终端设备在随机接入的过程中,网络设备需要为终端设备配置PRACH用于接入***。由于终端设备的移动使得终端设备和网络设备之间的距离是不确定的,所以如果终端设备需要发送消息到基站,则必须实时进行上行同步的维持管理。PRACH的目的就是为达到上行同步,建立终端设备和网络设备上行同步的关系以及请求网络设备分配给终端设备专用资源,使终端设备正常接入网络设备进行业务传输。
3、无线网络临时标识符(information-radio network temporary identifier,RNTI):RNTI用于区分或识别小区中连接的终端设备、特定无线信道或寻呼情况下的一组终端设备、接收功率控制参数的一组终端设备或者由网络设备为所有终端设备发送的***信息。RNTI可以是一个16位标识符,其值取决于RNTI的类型。其中,用于寻呼(paging)的RNTI记为P-RNTI。除此之外还有用于数据调度的小区无线网络临时标识(cell radio network temporary identifier,C-RNTI)、调制和编码方案小区无线网络临时标识(modulation and coding scheme cell radio network temporary identifier,MCS-C-RNTI)、配置调度无线网络临时标识(configured scheduling radio network temporary identifier,CS-RNTI)等。
4、物理下行控制信道(physical downlink control channel,PDCCH):UE是通过基站配置在搜索空间(search space)和控制资源集合CORESET(control resource set)确定基站可能发送PDCCH所占的时域、频域位置。
5、物理下行共享信道(physical downlink shared channel,PDSCH):NR下行数据的调度分为两类:一类是基于PDCCH动态调度的PDSCH,另一类是半静态调度的PDSCH;
动态调度就是发送一个PDCCH调度一个PDSCH,在每次发送PDSCH前,都需要发送一个PDCCH。PDCCH中包括调度的PDSCH的时域位置、频域位置等信息,终端设备根据这些信息去接收PDSCH。
而半静态调度就是网络设备发送一个PDCCH,这个PDCCH激活RRC信令配置的半静态调度配置,半静态配置包括PDSCH下发的周期,终端设备按照这个周期,周期性的接收PDSCH,PDSCH的在不同slot中的时域频域位置,都是根据激活PDCCH中的时域频域资源分配来确定的。
6、物理上行共享信道(physical downlink shared channel,PUSCH):当前PUSCH的发送也可以分为三类:
A、动态授权、dynamic grant、grant based,本质上就是基于PDCCH动态调度的PUSCH发送(调度机制类似基于PDCCH动态调度的PDSCH接收)。
B、configured grant type 1,基站通过RRC信令configuredGrantConfig给UE下发配置,信令包含rrc-ConfiguredUplinkGrant,UE如果有PUSCH发送的需求,可以直接按照这个配置发送PUSCH,不需要等待基站下发DCI调度或激活;这种方式也叫grant free的PUSCH
C、configured grant type 2,基站首先下发RRC层信令configuredGrantConfig(不包含rrc-ConfiguredUplinkGrant),然后UE需要接收到基站下发的DCI来激活该配置。UE激活之后,便在固定资源固定时间进行周期性的数据传输。这种方式也叫半静态的PUSCH(类似半静态PDSCH)。
7、信号参考信号(sounding reference signal,SRS)和信道状态信息(channel state information):SRS是UE发送给基站用于测量信道质量的信号;CSI是基站发送的CSI-RS,UE接收测量之后的上报信息;SRS和CSI上报,都是UE发送的上行信号,分为非周期/周期/半静态(A/P/SP,Aperiodic/Persistent/Semi Persistent)三种:
A-SRS/A-CSI,基于基站下发PDCCH触发的上行信号发送,触发一次发送一次(类似动态PDSCH/PUSCH调度);
P-SRS/P-CSI,是周期性的发送,即基站配置了SRS/CSI上报的RRC信令配置,UE按照这个配置周期的发送SRS/CSI上报;
SP-SRS/SP-CSI也是周期性发送,但是需要基站配置RRC配置并且需要基站下发PDCCH触发,UE才能按照配置周期性的发送;(类似configured grant type 2/SPS PDSCH)。
8、信道状态信息参考信号(channel state information reference signal,CSI-RS):CSI-RS是基站发送的下行参考信号,UE接收并测量(测量就在上述CSI上报中发送给基站);UE的CSI-RS测量行为,也分为A/P/SP三种:
A-CSI-RS,基于基站下发PDCCH告诉UE在哪里进行测量,触发一次测一次(类似动态
PDSCH/PUSCH调度);
P-CSI-RS,是周期性的测量,即基站配置了CSI-RS测量配置,UE按照配置周期的测量信道;
SP-CSI也是周期性的测量,但是需要基站配置CSI-RS测量配置并且需要基站下发PDCCH触发,UE才能按照配置周期性进行测量;(类似configured grant type 2/SPS PDSCH)。
9、非持续传输(dis-continuous transmission,DTX)机制:为了进一步降低通信设备的功率消耗,可以使能通信设备在一段时间内不发送数据传输,或者,可以使能通信设备在一段时间内不发送全部信道或者部分信道。这种降低通信设备功率消耗的方式可以称为DTX机制。
由于通信***的交互性,DTX对于通信的两个或者多个通信设备有不同的解读。对于发送设备,DTX可以理解为非持续发送机制,对于与配置了DTX的发送设备对应的接收设备,此时的接收设备在DTX可以理解为非持续接收机制。为方便描述,本申请中的DTX指代小区级的非持续传输机制,由于网络设备可以和小区内的多个终端设备通信,为方便描述,本申请中小区级的DTX也可以理解为网络设备DTX机制,通过网络设备DTX机制,可以实现网络设备的节能。
例如,网络设备可以设置一个传输图样,在一个传输周期内只在部分时间段上进行数据传输,在其他时间段都不进行数据收发。
当没有业务负载的时候,可以采用网络设备DTX机制,从而降低网络设备的功耗。
当业务负载很轻的时候,很多传输时间间隔上虽然有数据传输,但传输时间间隔的资源利用率很低,此时也可以采用网络设备DTX机制,通过将待发送的数据汇集到时间段A发送,从而可以在时间段B进入DTX状态,实现网络设备的静态节能。
10、非持续接收(dis-continuous reception,DRX)机制:使能终端只在规定时间段进行下行控制信道(physical downlink control channel,PDCCH)检测,但是该技术只对部分传输信道、信号起作用,基站并不能通过UE的DRX配置完全实现基站的静默。
DRX的基本机制是为处于无线资源控制(radio resource control,RRC)连接态的终端设备配置一个DRX周期。DRX周期由“持续时间(on Duration)”和“DRX的机会”(Opportunity for DRX)组成:在“持续时间”的时间段内,终端设备检测并接收物理下行控制信道(physical downlink control channel,PDCCH);而在“DRX的机会”的时间段内,终端设备不检测PDCCH以节省功耗。
其中,本申请中,将“持续时间”的时间段也称为激活时间段,将“DRX的机会”的时间段也称为去激活时间段。示例性地,图2为本申请提供的DRX基本模型的示意图。如图2所示,处于RRC连接态的终端设备周期性地进入激活时间段和去激活时间段,当终端设备进入激活时间段时,终端设备进行PDCCH的检测,而当终端设备进入去激活时间段时,终端设备不再进行PDCCH的检测,即不需要终端设备一直处于检测PDCCH的状态,从而达到降低终端功耗的目的。
目前,基站通过向终端设备发送DRX配置信息,以使得终端设备基于DRX配置信息在规定时间段内进入激活模式,而在其余时间进入去激活模式,以实现DRX机制下的休眠。具体地,在DRX配置中主要包括以下参数:
激活时间定时器(on Duration Timer):可以理解为一段连续的下行子帧数,表示终端设备在从休眠状态唤醒后所能维持的时间。在该段连续的下行子帧数内,终端设备需要侦听物理下行控制信道。
DRX非激活定时器(DRX–Inactivity Timer):同样可以理解为一段连续的下行子帧数。该DRX非激活定时器在终端设备成功解调出属于调度该终端设备新传(上行或下行)的PDCCH接收结束后的第一个符号启动,表示对应MAC在接收到一个指示新传的PDCCH后还需要监听PDCCH的时长。也就是说,在该DRX非激活定时器的定时时间段内也需要继续监听物理下行控制信道。
下行混合自动重传请求(hybrid automatic repeat request,HARQ)往返时延(round trip time,RTT)定时器(Timer)和下行DRX重传定时器(DRX–Retransmission Timer):当终端设备收到1个下行控制信息(downlink control information,DCI)指示一个物理下行共享控制信道(physical downlink shared channel,PDSCH)传输或者一个下行半持续调度(semi-persistent scheduling,SPS)的PDSCH传输被接收(不区分PDSCH是新传还是重传),终端设备会在承载该PDSCH传输的反馈信息“ACK/NACK”的物理上行控制信道(physical uplink control channel,PUCCH)的结束符号后的第一个符号起始时刻,启动下行HARQ-RTT-Timer并停止下行DRX重传定时器;当下行HARQ-RTT-Timer结束且终端设备没有成功接收该PDSCH传输,启动下行DRX重传定时器,如果终端设备成功接收该PDSCH传输,
则不启动下行Retransmission Timer。
上行混合自动重传请求(hybrid automatic repeat request,HARQ)往返时延(round trip time,RTT)定时器(Timer)和上行DRX重传定时器(DRX–Retransmission Timer):当终端设备收到1个DCI指示一个物理上行共享控制信道(physical uplink shared channel,PUSCH)传输或者一个上行配置授权(configured grant,CG)类型的PUSCH传输被激活,终端设备会在该PUSCH传输的第一个重复(repetition)的结束符号后第一个符号起始时刻,启动上行HARQ-RTT-Timer并停止上行行DRX重传定时器;当上行HARQ-RTT-Timer结束启动上行Retransmission Timer。
综上,终端设备在如下任一情况被认为是在激活时间段(Active Time),否则,认为是在去激活时间段(Inactive Time):激活时间定时器、DRX非激活定时器、下行DRX重传定时器、上行DRX重传定时器的运行期间。
此外,在DRX机制下,当终端设备发送调度请求且该调度请求处于悬挂“pending”状态,以及当终端设备基于非竞争随机接入过程结束后,终端设备收到PDCCH指示一个小区无线网络临时标识加扰的一个新传没有被成功接收时,终端设备也被认为是处于激活时间段。
也就是说,对于DRX机制,在激活时间定时器、DRX非激活定时器、下行DRX重传定时器、上行DRX重传定时器的运行期间、以及在终端设备发送调度请求且该调度请求处于悬挂“pending”状态和终端设备收到PDCCH指示一个小区无线网络临时标识加扰的一个新传没有被成功接收时,终端设备处于进行PDCCH的检测的时间段,而在其余时间段,终端设备处于不进行PDCCH检测的去激活时间段,以降低终端设备的功耗。
本申请中将去激活时间段也可以称为DRX机制下的休眠时间段。
该技术只对部分传输信道、信号起作用,基站并不能通过UE的DRX配置完全实现基站的静默。基站并不能通过UE的DRX配置完全实现基站的关断,也就是说,基站在inactive下仍然会发送部分下行信号,这一部分信号的发送导致基站的功耗增加,UE在inactive下仍然要接收这一部分信号,例如,1)SSB、PRACH,2)SI/RA/TC/P-RNTI、PS-RNTI加扰的DCI,3)SPS PDSCH,4)CG PUSCH,5)HARQ-ACK for SPS PDSCH,6)SR/BFR,因此UE会在DRX inactive Time接收如上信号,所以基站在UER的DRX inactive Time期间,也不能关断信号的传输,否则会影响UE接收。所以基站无法通过UE现有的DRX配置实现数据传输的关断,也就是无法做到基站侧的休眠。
从上文可见,UE DRX的inactive Time对一些传输并不生效,且现有的UE DRX配置是通过RRC信令配置的,两次重配时间较长,无法动态的根据业务负载的动态变化,灵活动态的调整UE接收数据的DRX配置,以达到最大限度的节能。
有鉴于此,本申请提供一种数据传输的方法,能够根据业务负载灵活的选择配置机制,从而可以实现双向的动态关断,降低功耗。
以下介绍本申请的具体方案。
图3是本申请提供的一种数据传输的方法的示意性流程图。

S420,网络设备向终端设备发送指示信息#1。
一种可能的实施方式中,该指示信息#1用于指示配置信息集合中的一个或多个DRX配置,例如,DRX配置#a。
相应的,终端设备从网络设备接收该指示信息#1,并根据指示信息#1的指示在配置信息集合中确
定DRX配置#a(如果指示信息#1指示多个DRX配置,则可以确定多个DRX配置,例如,DRX配置#a、DRX配置#b)。
本申请中,指示信息#1可以通过组播方式发送,也可以通过广播方式发送。
一种可选的理解,网络设备在某一个时频资源位置发送PDCCH/PDSCH,所有UE到相同的时频资源位置接收PDCCH/PDSCH。
作为示例而非限定,指示信息#1可以是广播或组播方式下发送的DCI,或者广播或组播方式下发送的PDSCH中承载的MAC-CE。
需要说明的是,上述指示信息#1不属于DRX配置控制的信号。即,指示信息#1的接收不受DRX配置的限制和影响。也即,即使在DRX配置的非激活态期间,UE仍然可以正常接收指示信息#1,从而实现动态的切换DRX配置。
本申请中,UE接收该指示信息#1,可以是在PCell上接收,或SCell上接收,或在PCell/SCell上都可以接收。本申请实施例对此不作限定。
一种可能的实现方式中,指示信息#1用于指示配置信息集合中的DRX配置#a,具体的指示方式可以是在指示信息#1中的比特域中指示。
作为示例而非限定,在指示信息#1中,设置比特域的取值和DRX配置的映射关系,该映射关系可以理解为比特域的取值与DRX配置的对应关系,换句话说,比特域的不同取值对应不同的DRX配置。
可以理解,DRX配置均为配置信息集合中的DRX配置。
以下以G-DCI或MAC-CE为例介绍指示信息#1的一种DRX配置的指示方法。
方法一:
G-DCI的一个比特域或者几个比特位的不同取值对应不同的DRX配置。
例如,配置信息集合中包括DRX配置#a、DRX配置#b、DRX配置#c和DRX配置#d,G-DCI的比特域是“00”,对于不同的UE来说,针对比特域取值“00”可以确定不同的DRX配置。例如,对于UE#1来说,该取值对应DRX配置#a,对于UE#2来说,该取值对应DRX配置#b。
当指示信息#1指示多个DRX配置(例如,DRX配置#a、DRX配置#b),对于UE#1来说,上述比特域取值“00”对应DRX配置#a和DRX配置#b。
具体的,UE可以根据映射DRX配置的索引的方式,或者是按照一定的顺序排列DRX配置来确定比特域取值和DRX配置的对应关系,本申请实施例对此不作限定。
方法二:
G-DCI中的比特位置对应不同的UE,比特位置对应比特取值对应UE的DRX配置。
例如,配置信息集合中包括DRX配置#a、DRX配置#b、DRX配置#c和DRX配置#d,G-DCI的比特域是“00 01 10”,对于不同的UE来说,可以找到对应的比特位,进而根据比特位的取值确定对应的DRX配置。例如,UE#1对应“00”位置,UE#1根据该取值确定对应DRX配置#a;再例如,UE#2对应“01”位置,UE#2根据该取值确定对应DRX配置#c。
当指示信息#1指示多个DRX配置(例如,DRX配置#a、DRX配置#b),对于UE#1来说,UE#1对应“00”位置,UE#1根据该取值确定对应DRX配置#a和DRX配置#b。
以上举例仅为示例性说明,对本本申请实施例不作任何限定。
需要说明的是,上述方式仅为举例,通过比特域指示配置信息的任何可能的实施方案均可适用于本申请实施例。
S430,终端设备根据DRX配置#a不接收和/或不发送信号#a。
可以理解,当指示信息#1指示多个DRX配置(例如,DRX配置#a、DRX配置#b),终端设备根据DRX配置#a和DRX配置#b不接收和/或不发送信号#a和信号#b。
本申请中,终端设备根据指示的DRX配置来确定不接收下行信号或者不发送上行信号。
其中,信号#a为DRX配置#a可以控制发送或接收的信号。
需要说明的是,当指示信息#1指示多个DRX配置,则终端设备根据该多个DRX配置控制多个信号的发送或接收状态。
一种可能的实施方式中,当多个DRX配置控制的信号没有重复,则终端设备根据该多个DRX配
置可以控制多个信号的发送或接收,即,对应的信号按照不同DRX配置进行接收或发送。
一种可能的实施方式中,当多个DRX配置控制的信号有重复,也就是说,部分信号相同,则相同的信号可以按照一个DRX配置进行接收或发送。换句话说,根据其中一套配置中的on Duration Time和inactive Time进行周期性的接收或发送。
其中,可以按照配置索引相对较小的一个配置进行上述信号的接收或发送,也可以按照非激活时间持续时间最长的一个配置进行上述信号的接收或发送,也可以按照DRX循环周期最长的一个配置进行上述信号的接收或发送。本申请实施例对此不做限定。
图5示出了多个DRX配置控制多个信号发送或接收的一种方法示意图。如图5中所示,配置信息集合包括三个DRX配置,包括DRX配置#1,DRX配置#2,DRX配置#3,其中,三个DRX配置都控制DG PUSCH,DRX配置#1还控制DG PDSCH,终端设备根据指示信息#1使用DRX配置#1,DRX配置#2,如图中所示,终端设备可以在DRX配置#1的on Duration Time进行DG PDSCH的接收;终端设备可以在DRX配置#2的on Duration Time进行DG PUSCH的发送。
可以理解,终端设备发送上行DG PUSCH时,确定DRX cycle周期最长的DRX配置为DRX配置#2,则在DRX配置#2的on Duration Time进行DG PUSCH的发送。
应理解,以上仅为示例性说明,终端设备也可以按照配置索引相对较小的一个配置进行上述信号的发送,或是按照非激活时间持续时间最长的一个配置进行上述信号的发送,本申请实施例对此不作限定。
一种可能的实施方式中,当多个DRX配置控制的信号有重复,也就是说,部分信号相同,则相同的信号可以按照两个DRX配置进行接收或发送。换句话说,根据两套配置中的on Duration Time和inactive Time进行周期性的接收或发送。
图6示出了多个DRX配置控制多个信号发送或接收的另一种方法示意图。如图6中所示,配置信息集合包括三个DRX配置,包括DRX配置#1,DRX配置#2,DRX配置#3,其中,三个DRX配置都控制DG PUSCH。终端设备根据指示信息#1使用DRX配置#2和DRX配置#3,如图中所示,终端设备可以在DRX配置#2和DRX配置#3的on Duration Time都进行DG PUSCH的发送。
可以理解,终端设备发送上行DG PUSCH时,确定DRX cycle周期最长的DRX配置为DRX配置#3,则在DRX配置#3的on Duration Time进行DG PUSCH的发送。
应理解,以上仅为示例性说明,对本申请实施例不作任何限定。
S440,终端设备根据DRX配置#y不接收和/或不发送信号#y。
当满足第一条件时,DRX配置#a可以理解为失效,则使用DRX配置#y不接收和/或不发送信号#y。
可以理解,当指示信息#1指示多个DRX配置(例如,DRX配置#a、DRX配置#b),当满足第一条件时,DRX配置#a和DRX配置#b可以理解为失效,则使用DRX配置#y不接收和/或不发送信号#y。
其中,DRX配置#y为原有的DRX配置或是默认的DRX配置。
其中,信号#y包括如下信号中至少一种:C/CS/SFI/INI/CI/TPC-PUCCH/TPC-PUSCH/TPC-SRS/AI-RNTI加扰的PDCCH、动态调度的PDSCH、DG PUSCH、动态调度PDSCH的HARQ-ACK、A/P/SP-SRS和A/P/SP-CSI。
一种可能的实施方式中,终端设备从网络设备接收指示信息#2,该指示信息#2指示DRX配置#y。
一种可能的实施方式中,DRX配置#a中包括第一定时器,当该第一定时器超时,则可以激活DRX配置#y。
一种可能的实施方式中,终端设备向网络设备发送特定信号,网络设备收到该特定信号后发送确认信息确认终端设备可以切换至DRX配置#y。
根据本申请实施例的方案,终端设备可以根据网络设备的指示,采用不同的DRX配置控制不同信号的发送或接收状态,能够根据业务负载灵活的选择配置机制,从而可以实现网络设备和终端设备双向的动态关断,降低功耗。
