Description

通信方法及装置 技术领域
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
在长期演进(Long Term Evolution,LTE)中,已经引入了小数据传输(early data transmission,EDT)。在小数据传输过程中,终端设备可能始终保持在空闲(idle)态或者中止(suspend)状或者非激活(inactive)态,来完成上行和/或下行小数据包的传输。
在数据传输过程中,可能会触发功率余量报告(Power Headroom Reporting,PHR)。PHR会将估计的上行传输功率和终端设备的最大发射功率之差上报给网络设备,从而帮助网络设备对终端设备进行功率控制以及上行调度。
然而,在小数传输过程中,若存在已触发的PHR,由于PHR的媒质接入控制单元(Medium Access Control Communication Edge,MAC CE)具有更高的逻辑信道优先级,PHR MAC CE会优先于数据传输。小数据传输的过程要求终端设备保持在非激活态完成数据传输,从而使得终端设备需要在一段时间内完成少量数据的传输。由于PHR MAC CE传输需要占用部分数据传输资源,进而会导致需要更多次的上行调度才能完成全部待传输数据的上传。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
首先对于小数据传输进行说明。
在长期演进(Long Term Evolution,LTE)中,已经引入了小数据传输(early data transmission,EDT)。在小数据传输过程中,终端设备可能始终保持在空闲(idle)态或者中止(suspend)状或者非激活(inactive)态,来完成上行和/或下行小数据包的传输。在配置上,网络设备会在第二系统信息块(System Information Block 2,SIB2)上配置一个当前网络允许传输的最大传输块(Transport Block,TB)大小,终端设备判断自己待传输的数据量,如果待传输的数据量小于网络设备广播的最大TB大小,则终端设备可以发起EDT传输。如果待传输的数据量大于或等于网络设备广播的最大TB大小,终端设备UE使用正常的连接建立过程,进入连接态传输数据。若终端设备发起上行EDT的小区与最后的服务小区相同,则网络设备在收到终端设备发送的连接恢复请求及上行数据后,可以直接将上行数据递交给核心网设备。
其次对于配置上行资源(Preconfigured Uplink Resource,PUR)进行说明。
在LET R16中,针对窄带物联网(Narrow Band Internet of Things,NB-IoT)和增强机器类通信(LTE enhanced MTO,eMTC)场景,引入了在空闲态利用预配置上行资源(Preconfigured Uplink Resource,PUR)进行数据传输的方法。图1为现有的PUR传输的流程示意图。如图1所示,PUR只在当前配置的小区内有效,即当终端设备检测到小区变化,并在新的小区发起随机接入时,终端设备需要释放原小区配置的PUR。PUR传输流程和LTE UP-EDT相比,省去了发送前导码获取定时提前量(time advance,TA)和上行授权(UL grant)的过程。
再次对于功率余量报告(Power Headroom Reporting,PHR)进行说明。
PHR的过程是将估计的上行传输功率和终端设备的最大发射功率之差上报给网络设备,从而帮助网络设备对终端设备进行功率控制以及上行调度。其中,PHR可以通过终端设备的最大发射功率减去物理上行共享信道(Physical Uplink Shared Channel,PUSCH)发 射功率确定,或者通过终端设备的最大发射功率减去PUSCH发射功率和物理上行控制信道(Physical Uplink Control Channel,PUCCH)这和确定。
现有的PHR的触发条件可以包括以下至少一项:上报时间定时器(phr-ProhibitTimer)超时且与前一次传输的PHR相比路径变化量超过阈值(phr-Tx-PowerFactorChange dB)、周期性上报定时器(phr-PeriodicTimer)超时、上层配置或重配置功率余量报告且不用于指示禁用功率余量报告功能、新增或改变主辅小区(Primary Secondary Cell,PSCell)、激活任何MAC实体的辅小区(Secondary Cell,SCell)且该MAC实体的配置的上行链路的第一活跃下行带宽标识(firstActiveDownlinkBWP-Id)为休眠带宽部分((Bandwidth Part)。
现有的PHR过程中,若网络设备为终端设备分配了上行资源用于新数据传输,且此时PHR被触发,并且所分配的资源足够携带PHR相应的MAC CE。则MAC层从物理层获得功率余量信息,并将PHR MAC CE组装在MAC分组数据单元(Packet Data Unit,PDU)中,进行PHR的上报。在单小区场景下,即没有配置双连接(Dual Connectivity,DC),也没有配置上行载波聚合(UL Carrier Aggregation,UL CA)的场景下,终端设备上报单个小区的PHR。在多无线制式双连接(Multi-RAT Dual Connectivity,MR-DC)场景下,终端设备会上报终端设备所有激活态小区的PHR,包括主小区组(Master Cell Group,MCG)侧的小区和辅小区组(辅小区组,SCG)侧的小区。
最后对于5G NR中的小数据传输进行说明。
在5G新空口(5G NR)系统中,无线资源控制(Radio Resource Control,RRC)状态分别为:RRC空闲态、RRC非激活态和RRC连接态。其中RRC非激活态是5G系统从节能角度考虑引入的新状态,对于RRC非激活态的终端设备,无线承载和全部无线资源都会被释放,但终端设备侧和网络设备侧保留终端设备接入上下文,以便快速恢复RRC连接。网络设备通常将数据传输不频繁的终端设备保持在RRC非激活态。Rel-16之前,处于RRC非激活态的终端设备不支持数据传输,当发起(Mobile Original,MO)或接收(Mobile Terminated,MT)数据到达时,终端设备需要恢复连接,待数据传输完成后再释放到RRC非激活态。对于数据量小且传输频率低的终端设备,上述传输机制会导致不必要的功耗和信令开销。因此,Rel-17立项开展对RRC非激活态下小数据传输(Small Data Transmission,SDT)(与EDT含义相同)的研究,从而实现基于随机接入过程(两步/四步)的上行小数据传输以及基于预配置资源的上行小数据传输。
然而,现有的PHR流程中,PHR以MAC CE的形式上报给网络。根据现有逻辑信道优先级顺序,PHR MAC CE的优先级高于DTCH。在SDT过程中,若存在触发的PHR(pending PHR),由于PHR MAC CE具有更高的逻辑信道优先级,PHR MAC CE会优先于数据传输。SDT要求终端设备保持在RRC非激活态完成数据传输,从而使得终端设备需要在一段时间内完成少量数据的传输。由于PHR MAC CE传输需要占用部分数据传输资源,会导致需要更多次的上行调度才能完成全部上行数据的传输。
为解决上述技术问题,本申请实施例提供一种通信方法及装置,终端设备在小数据传输触发功率余量报告时,可以基于上行资源和待传输数据来确定上行数据中是否包含功率余量报告,避免了一些情况下不必要的功率余量报告,进而避免了由于功率余量报告的媒体介入控制单元占用部分数据传输资源而导致的需要更多次的上行调度才能完成全部待传输数据的上传。
需要说明的是,本申请实施例的技术方案可以应用于各种通信系统,本申请实施例对此不做限制。例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演 进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。

下面以终端设备和网络设备为例,以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本申请实施例提供的一种通信方法的信令交互图。本申请实施例的执行主体为终端设备和网络设备,涉及的是终端设备如何确定第一上行数据中所包含的内容的具体过程。如图3所示,该方法包括:
S201、终端设备在小数据传输时触发功率余量报告。
其中,小数据传输为终端设备保持在空闲态或中止状或者非激活态,来完成上行和/或下行小数据包的传输。在小数据传输中,终端设备传输的数据量需要小于网络设备广播的最大TB大小。
应理解,本申请实施例对于小数据传输的类型不做限制,示例性的,可以包括基于随机接入的小数据传输(RA-SDT)或基于预配置资源的小数据传输(CG-SDT)。
在本申请中,终端设备在进行小数据传输时,可以由于某些条件触发功率余量报告。本申请实施例对于功率余量报告的触发条件也不做限制,示例性的,功率余量报告的触发 条件包括以下至少一项:上报时间定时器超时且与前一次传输的功率余量报告相比路径变化量超过阈值、周期性上报定时器超时、上层配置或重配置功率余量报告且不用于指示禁用功率余量报告功能、当前无触发的功率余量报告且当前上行资源的容量小于待传输的数据量。
需要说明的是,在本申请实施例中,可以由上述一个触发条件触发功率余量报告,也可以由上述多个条件触发功率余量报告,本申请实施例对此不做限制
此外,本申请实施例对于上报时间定时器和周期性上报定时器均不作限制,示例性的,上报时间定时器可以为phr-ProhibitTimer,周期性上报定时器可以为phr-PeriodicTimer。本申请实施例对于路径变化量的阈值也不做限制,可以根据实际情况具体设置,例如,路径变化量的阈值可以为phr-Tx-PowerFactorChange dB。
S202、终端设备根据待传输的数据量和第一上行资源,确定第一上行数据中是否包含功率余量报告。
在本步骤中,当终端设备在小数据传输时触发功率余量报告后,终端设备可以先获取第一上行资源,再根据待传输的数据量和第一上行资源,确定第一上行数据中是否包含功率余量报告。
应理解,本申请实施例中,第一上行资源可以为一种,也可以为多种,本申请实施例对此不做限制。示例性的,第一上行资源包括以下至少一项:通过随机接入响应(Random Access Response,RAR)调度的上行授权(UL grant)、用于传输两步随机接入(MsgA)有效载荷(payload)的物理上行共享信道资源、网络设备通过动态调度配置的上行资源、预配置的半静态资源。
应理解,第一上行资源用于传输第一上行数据,第一上行数据为终端设备在小数据传输过程中传输给网络设备的数据,第一上行数据的传输可以为当前小数据传输过程中的第一次数据传输,也可以为小数据传输过程中第一次传输后的数据传输,即后续(subsequent)传输,本申请实施例对此不做限制。
在本申请中,当终端设备获取到第一上行资源后,可以确定第一上行数据所包含的内容中是否包含功率余量报告。
应理解,本申请实施例对于如何确定第一上行数据中是否包含功率余量报告不做限制,在一些实施例中,终端设备可以通过判断是否有必要进行率余量报告来确定第一上行数据中是否包含功率余量报告。
示例性的,若第一上行资源的容量大于或等于待传输的数据量,终端设备没有必要进行功率余量上报,则第一上行资源可以容纳全部待传输的数据,第一上行数据中可以不包含功率余量报告。相应的,终端设备可以取消所有已触发的功率余量报告,按照现有链路控制协议(Link Control Protocol,LCP)流程组建MAC PDU,进而通过第一上行资源将第一上行数据发送给网络设备。
示例性的,若第一上行资源的容量小于待传输的数据量,则第一上行资源不能容纳全部待传输的数据,则终端设备需要进行功率余量报告,此时若第一上行资源的容量大于或等于功率余量报告的媒体介入控制单元和子包头之和,则第一上行数据中包含功率余量报告。相应的,终端设备生成功率余量报告的媒体介入控制单元,并按照现有LCP流程组建MAC PDU。随后,终端设备将功率余量报告的媒体介入控制单元和MAC PDU作为第一上行数据发送给网络设备。
需要说明的是,本申请实施例中功率余量报告承载于功率余量报告的媒体介入控制单元中。本申请实施例对于功率余量报告的媒体介入控制单元的类型不做限制,示例性的,功率余量报告的媒体介入控制单元可以为单次(Single Entry)媒质接入控制单元或多次(Multiple Entry)媒质接入控制单元或小数据传输引入的媒质接入控制单元。
需要说明的是,本申请实施例中按照现有LCP流程组建MAC PDU可以基于小数据传 输流程组建,MAC PDU中可以包含待传输的数据。
可选的,在一些实施例中,若终端设备配置有双链接或聚波载合,则终端设备在计算功率余量报告时不受限于或不执行动态功率共享配置,认为终端设备最大传输功率全部用于终止于主节点(Master Node,MN)的主小区组(Master Cell Group,MCG)数据传输。
示例性的,若终端设备的最大发射功率为A,采用动态功率共享配置,则用于主小区(Primary Cell,PCell)数据发送的功率为B,其余A-B的功率用于其他小区的数据发送。而在本申请中,由于SDT不恢复CA、DC配置,因此在SDT过程中的PHR计算可以不受限于或不执行动态功率共享配置,从而使得终端设备可以采用更大的上行功率进行数据传输,进而提升数据传输的可靠性。
S203、终端设备使用第一上行资源将第一上行数据发送给网络设备。
应理解,本申请实施例对于如何使用第一上行资源传输第一上行数据不做限制,可以使用常用的上行数据传输方案。
本申请实施例提供的通信方法,终端设备先在小数据传输时触发功率余量报告。随后,终端设备根据待传输的数据量和第一上行资源,确定第一上行数据中是否包含功率余量报告,第一上行资源用于传输第一上行数据。通过该方式,终端设备可以基于上行资源和待传输数据来确定上行数据中是否包含功率余量报告,进而避免了由于功率余量报告的媒体介入控制单元占用部分数据传输资源而导致的需要更多次的上行调度才能完成全部待传输数据的上传。

本申请实施例对于如何判断第一上行数据中是否包含功率余量报告不做限制,在一些实施例中,若第一上行资源的容量大于或等于待传输的数据量,则第一上行数据中不包含功率余量报告。在另一些实施例中,若第一上行资源的容量小于待传输的数据量且第一上行资源的容量大于或等于功率余量报告的媒体介入控制单元和子包头之和,则第一上行数据中包含功率余量报告。
