Definitions
- the present application relates to the field of communications, and more particularly to a method, network device and terminal device for transferring uplink information without authorization.
- the terminal device before transmitting uplink data, the terminal device first needs to establish a radio resource control connection with the base station, enter a radio resource control connection state, and obtain an authorization instruction of the base station. After that, the uplink data can be sent according to the instruction of the base station. This method of transmitting data upstream is called an authorized transmission. Since the terminal device needs to send data to and from the air interface to determine that there is uplink data, a large amount of signaling interaction is required, and therefore, the delay of the authorized transmission is large.

Description
本申请要求于2016年9月30日提交中国专利局、申请号为201610870865.2、申请名称为“免授权的传输上行信息的方法、网络设备和终端设备”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。
本申请涉及通信领域,并且更具体地,涉及一种免授权的传输上行信息的方法、网络设备和终端设备。
无线蜂窝网络,例如,长期演进(Long Term Evolution,LTE)系统中,终端设备在发送上行数据之前,首先需要与基站建立无线资源控制连接,进入无线资源控制连接状态,并在获得基站的授权指令后,才能根据基站的指令要求发送上行数据。这种上行发送数据的方法称为授权传输。由于终端设备从确定有上行数据需要发送到从空口将数据发送出去,需要大量的信令交互,因此,授权传输的时延较大。
大规模机器通信是未来第五代通信技术中的一个重要应用场景。在MTC通信场景下,终端设备的数量庞大,业务类型以小数据包业务为主,而且对低时延有一定的要求。这种场景中,免授权传输被认为是一种优于授权传输的传输上行数据方法。免授权传输的基本思想是数据“即来即走”,即终端确定有上行数据要发送时,不必经过发送上行调度请求和等待接收基站的授权指令交互过程,而是直接将数据经过的一定处理后发送给基站。
而低时延高可靠性通信(Ultra-Reliable Low Latency Communication,URLLC)也是5G中的重要场景。对车联网、无人驾驶、工业控制等一些业务来说,系统容量并不是主要的问题,但是对于时延和可靠性却有着很高的要求。因此,免授权传输被认为是更加适用于低时延高可靠性的场景。
现有技术中提供的免授权的传输上行信息的方法,是在连续上行子帧上多次发送同一个传输块TB而无需等待确定应答(Acknowledgement,ACK)或否定应答(Negative Acknowledgement,NACK),这种技术称为子帧捆绑(Transmission Time Interval Bundling,TTI Bundling)。但是子帧捆绑技术仅仅利用了时间上的分集来缩短时延,灵活性较低。

下面将结合附图,对本申请中的技术方案进行描述。
本申请提供的技术方案,可以应用于无线蜂窝网络的各种通信系统,例如:全球移动通信(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 Wireless,WCDMA)系统,通用分组无线业务(General Packet Radio Service,GPRS)系统,长期演进(Long Term Evolution,LTE)系统,通用移动通信系统(Universal Mobile Telecommunications System,UMTS),下一代移动通信系统(例如,5G),和机器与机器(Machine to Machine,M2M)通信系统等。
首先,对本申请实施例涉及到的相关概念作简单介绍。
应理解,传统的授权频谱资源一般需要国家或者地方无线委员会审批才可以使用的频谱资源。不同系统(例如,LTE系统、WiFi系统)或不同运营商的系统不可以共享使用授权频谱资源。
传统的免授权频谱资源传输是指无需系统分配,各个通信设备可以共享使用免许可频谱包括的资源。免许可频段上的资源共享是指对特定频谱的使用只规定发射功率、带外泄露等指标上的限制,以保证共同使用该频段的多个设备之间满足基本的共存要求。
需要说明的是,本申请实施例所描述的免授权传输有别于上述免授权频谱资源传输,需要经过用户接入网络和基站为用户分配免授权传输资源的过程。当用户有数据需要发送时,直接在基站分配的免授权资源上发送。因此,本申请实施例中所述的免授权频谱资源传输与传统的免授权频谱资源传输不同的是,本申请实施例中用于免授权传输的资源需要系统预先分配。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与移动台通信的设备,网络设备可以是无线局域网(Wireless Local Area Networks,WLAN)中的接入点(ACCESS POINT,AP),GSM或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS)。也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
在本申请实施例中,网络设备能够通过上述免授权传输进行无线通信。另外,网络设备也可以通过授权频谱资源传输进行无线通信。
本申请结合终端设备描述了各个实施例。终端设备也可以称为用户设备(User
Equipment,UE)、移动台、接入终端、用户单元、用户站、移动站、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等。终端设备可以是无线局域网(Wireless Local Area Networks,WLAN)中的站点(STAION,ST),可以是蜂窝电话、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、个人数字处理(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、可穿戴设备以及未来通信网络(例如,5G)中的移动台或者未来演进的PLMN网络中的终端设备等。
在本申请实施例中,终端设备能够通过上述免授权传输进行无线通信。另外,终端设备也可以通过授权频谱资源传输进行无线通信。
本申请实施例中所述的网络设备和终端设备可以如图1中所示的计算机设备(或系统)100的方式来实现。
图1是本申请实施例提供的计算机设备(或系统)100的示意图。其中,计算机设备100包括至少一个处理器101、存储器102、通信总线103和至少一个通信接口104。
处理器101可以为中央处理器(CPU)、微处理器、特定应用集成电路(application-specific integrated circuit,ASIC),或一个或多个用于控制本申请技术方案程序执行的集成电路。
存储器102可以是只读存储器(read-only memory,ROM)或可存储静态信息和指令的其他类型的静态存储设备,随机存取存储器(random access memory,RAM)或者可存储信息和指令的其他类型的动态存储设备,也可以是电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory,EEPROM)、只读光盘(Compact Disc Read-Only Memory,CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质,但不限于此。存储器可以是独立存在,也可以和处理器集成在一起。
其中,存储器102用于存储执行本申请技术方案的应用程序代码,处理器101用于执行存储器102中存储的应用程序代码。
在具体实现中,作为一种实施例,处理器101可以包括一个或多个CPU。例如图1中所示的CPU0和CPU1。
在具体实现中,作为一种实施例,计算机设备100可以包括多个处理器,每个处理器可以是一个单核(single-CPU)处理器,也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
在具体实现中,作为一种实施例,计算机设备100还可以包括输出设备105和输入设备106。输出设备105和处理器101通信,可以以多种方式来显示信息。例如,输出设备105可以是液晶显示器(Liquid Crystal Display,LCD),发光二级管(Light Emitting Diode,LED)显示设备,阴极射线管(cathode ray tube,CRT)显示设备,或投影仪(projector)等。输入设备106和处理器101通信,可以以多种方式接受用户的输入。例如,输入设备可以是鼠标、键盘、触摸屏设备或传感设备等。
上述的计算机设备100可以是一个通用计算机设备或者是一个专用计算机设备。在具体实现中,计算机设备100可以是台式机、便携式电脑、网络服务器、掌上电脑(Personal Digital Assistant,PDA)、移动手机、平板电脑、无线终端设备、通信设备、嵌入式设备或有图1中类似结构的设备。本申请实施例不限定计算机设备100的类型。
应理解,在本申请实施例中,编号“第一”、“第二”仅仅为了区分不同的对象。例如,为了区分不同的指示信息,不应对本申请实施例的保护范围构成任何限定。
还应理解,以下各个实施例的方法中所示的步骤或操作仅仅作为示例,也可以执行其他操作或者各种操作的变形。并且,在具体实施时,各个步骤还可以按照与本申请实施例中所述的不同的顺序来执行,并且有可能并非执行本申请实施例所示出的全部操作或步骤。或者,也可能执行本申请各实施例所示出的更多的操作或步骤。
为了便于理解和说明,以下仅以UE和基站分别作为终端设备和网络设备的示例,对本申请实施例的免授权的传输上行信息的方法进行说明。
图2示出了本申请实施例的免授权传输上行信息的方法的示意性交互图。如图2所示,该方法主要包括步骤210至步骤230。
210、UE确定承载至少一个冗余版本的多个目标多接入资源MAR,每个冗余版本至少包括该终端设备需要发送给基站的上行信息,该多个目标MAR能够通过频率分集或签名分集进行区分。
应理解,一个多接入资源(Multiple Access Resource,MAR)由一个多接入物理资源(Multiple Access Physical Resource,MAPR)和一个多接入签名(MA Signature,MAS)构成。其中,MAPR专指时频资源(Time Frequency Resource)。而MAS至少包括以下一种但不限于:码本(Codebook)、码字(Codeword)、序列(Sequence)、交织图样(Interleaver pattern)、映射图样(mapping pattern)、解调参考信号(Demodulation reference signal)、前导字(Preamble)、空域(Spatial-dimension)和功率域(Power dimension)。
可选地,作为一个实施例,该多个目标MAR能够通过频率分集、签名分集和时间分集的任意组合进行区分。
需要说明的是,UE在发送上行信息时,可以发送一个冗余版本或多个冗余版本,本申请实施例对此不作任何限定。
这里所说的一个冗余版本是指仅有一个版本号。多个冗余版本是指多个版本号。应理解,本申请实施例中所述的冗余版本(Redundancy Version,RV)用于实现增量冗余(Incremental redundancy,IR)的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ),即,将对传输块(Transport Block,TB)生成的冗余比特(Redundancy Bit)分成若干组,每个RV定义一个传输起始点,首次传输和各次重传分别使用不同的RV,以实现冗余比特的逐步积累,完成增量冗余HARQ。更具体地,关于冗余版本的详细说明也可以参考现有技术中的定义,这里不做详述。特别地,当各个MAR上发送的冗余版本一致时,这种增量冗余的方法就变成Chase Combining(蔡司合并,简称为CC)方法。
具体地,在本申请实施例中,UE确定承载至少一个冗余版本的多个目标MAR,包括多种方式。
方式1
UE根据捆绑信息确定目标MAR,其中,捆绑信息是终端设备和网络设备预先约定的。
其中,捆绑信息可以与以下几种因素相关:
是否重传:UE在重传时可以使用与初传相同的捆绑信息,也可以使用域初传不同的捆绑信息。例如,UE可以在重传时增加RV的数量、增加MAR的数量或将RV放置在分集更高的MAR上等。
UE的服务质量(Quality of Service,QoS):UE针对不同QoS要求的数据包,使用不同的捆绑信息。例如,对于时延要求较高的数据包,尽量选择频率分集或签名分集而不是时间分集。或者,基站可以通过系统的预设规则尝试在更短的时间内进行译码。又例如,针对可靠性要求较高的数据包,可以传输更多的RV、增加占用RV占用的MAR数量,将RV放置在分集更高的MAR上等。
具体地,本申请实施例中所述的捆绑(Bundling)信息可以包括以下信息中的至少一个:发送上行信息时使用冗余版本的数量、发送上行信息时使用的冗余版本占用MAR的数量和大小、MAR的位置、发送所述上行信息时使用的冗余版本与MAR的映射关系、每个MAR上承载冗余版本的数量和每个MAR能够使用的调制与编码策略(Modulation and Coding Scheme,MCS)。
可选地,作为一个实施例,该多个目标MAR中的每个目标MAR携带UE的标识信息和所承载的冗余版本的版本号,每个目标MAR携带有第二控制信道,第二控制信道上承载有第二指示信息,第二指示信息用于指示该标识信息和版本号,以便于基站对该至少一个冗余版本进行合并,得到上行信息。
在承载有冗余版本的MAR(即,目标MAR)携带有UE的标识信息和RV的版本号时,每个目标MAR可以单独携带控制信道(即,第二控制信道),控制信道上承载有UE标识信息和RV版本号的指示信息(即,第二指示信息)。这样,基站在接收到RV时,同时接收到携带在MAR上的UE的标识信息和RV的版本号。基站基于UE的标识信息和版本号能够获知每个RV的版本号和该RV所属的UE,从而可以对每个UE的RV进行合并译码。
即,在方式1中,UE发送冗余版本时使用哪些MAR完全是根据系统定义确定。这里,系统定义可以指由基站和UE预先约定。或者,系统定义也可以指由标准规定。
方式2
UE参考捆绑信息确定。
可选地,作为一个实施例,UE确定承载至少一个冗余版本的多个目标MAR,包括:
UE根据捆绑信息,确定至少一个冗余版本对应的多个第一MAR,其中,捆绑信息是该UE与网络设备预先约定的,捆绑信息中包括以下信息中的至少一个:发送上行信息时使用冗余版本的数量、发送上行信息时使用的冗余版本占用MAR的数量和大小、该多个第一MAR的位置、发送上行信息时使用的冗余版本与该多个第一MAR的映射关系、每个第一MAR上承载冗余版本的数量和每个第一MAR能够使用的调制与编码策略MCS;
UE从该多个第一MAR中确定该多个目标MAR。
应理解,这里的第一MAR是指系统定义的承载RV的MAR。目标MAR是UE从多个第一MAR中确定的在实际发送RV时使用的MAR。
可以理解的是,在方式2中,网络侧仅能够获知系统预先定义MAR(即,网络侧仅知道第一MAR),而并不知道UE实际发送RV时使用的MAR。因此,UE需要告知网
络设备实际发送RV时使用的MAR(即,目标MAR)。
可选地,作为一个实施例,该方法还包括:
UE向网络设备发送第三控制信道,第三控制信道上承载有第三指示信息,第三指示信息用于指示该UE基于捆绑信息确定的该多个目标MAR,以便于网络设备根据捆绑信息和第三指示信息,在该多个第一MAR中的目标MAR上接收所述至少一个冗余版本。
可见,在方式2中,UE在捆绑信息的基础上确定目标MAR。与上方式1不同的是,在这种方式中,UE仅是将系统定义作为发送RV时的参考。因此,UE发送的承载RV的MAR(即,目标MAR)可能并不是完全按照系统定义。这种方式中,UE需要告知基站自己选定的发送RV的MAR。
方式3
UE自主确定。
可选地,作为一个实施例,该方法还包括:
UE向网络设备发送第一控制信道,第一控制信道上承载有第一指示信息,第一指示信息用于指示该多个目标MAR,以便于网络设备根据第一指示信息在该多个目标MAR上接收该至少一个冗余版本。
可以理解的是,由于在方式3中,UE发送RV时使用的MAR(即,目标MAR)可以完全是由UE自己确定。因此,在这种方式中,UE也需要将自己选定的承载RV的MAR告知网络侧。
UE基于以上多种方式确定了目标MAR后,会在目标MAR上向基站发送一个或多个冗余版本。每个冗余版本都至少包括了UE需要发送给基站的上行信息。
下面结合多个实施例,详细说明本申请实施例的目标MAR(即,用于承载冗余版本RV的MAR)。
图3示出了UE发送一个冗余版本的一种方式。如图3所示,UE每次发送一个传输块(Transport Block,TB),且TB只有一个冗余版本。
应理解,在本申请各个实施例中所述的一个冗余版本是指UE发送给网络侧的冗余版本的版本号相同,即,仅有一个版本号。同样的,多个冗余版本是指UE发送给网络侧的冗余版本有多个版本号。
以下,对目标MAR上仅承载一个冗余版本的情况进行说明。
图4示出了本申请一实施例的MAR的示意图。在本实施例中,将时间连续,采用相同多接入签名(Multiple Access Signature,MAS),长度固定的时频资源块定义为一个资源组。每个资源组中包括的多个MAR可以采用不同的调制与编码策略(modulation and coding scheme,MCS)。其中,每个资源组的划分在传输上行信息前由UE和基站已知。
本申请各个实施例中所述的资源组可以是UE自己选择,或者也可以采用半静态配置的方式。
应理解,这里所述的半静态配置是指UE初次发送RV时基于网络侧的预先配置,并存储网络侧的配置信息。每隔一定周期,UE使用与初次发送RV时相同的MAR资源发送RV。
如图4所示,UE#1选取资源组#1,UE#2选取资源组#3,UE#3选取资源组4。对于每个UE而言,将包括上行信息的冗余版本放置在所选资源组中的所有MAR上。
相对应地,在网络侧,基站将每个资源组上所有MAR上的冗余版本进行合并译码。在译码正确的情况下,基站可以获得UE发送的上行信息。
图5示出了本申请另一实施例的MAR的示意图。如图5所示,在本实施例中,将时间连续,采用相同多接入签名、长度不固定的时频资源块定义为一个资源组。
如图5所示,资源组#1、资源组#2与资源组#3、资源组#4有着不同的长度。UE#1选择资源组#1,UE#2选择资源组#3。UE#3选择资源组#4。UE将各自TB的RV放置在选定资源组中的每个MAR上。
相对应地,在网络侧,基站将每个资源组包括的所有MAR上的冗余版本进行合并译码,得到UE发送的上行信息。
图6示出了本申请再一实施例的MAR的示意图。在本实施例中,将时间不连续、采用相同多接入签名、长度不固定的时频资源块定义为一个资源组。在每个资源中,放置(或者说,承载)冗余版本多个MAR在时域上可以为连续的,或者也可以不连续。
如图6所示,资源组#1在时域上不连续。资源组#3和资源组#4在时域上连续。其中,UE#1选择资源组#1,UE#2选择资源组3,UE#3选择资源组4。每个UE分别将各自的TB产生的RV放置在选定资源组的每个MAR上。
相对应地,基站将每个资源组上所有MAR上的冗余版本进行合并译码,得到UE发送的上行信息。
图7示出了本申请又一实施例的MAR的示意图。在本实施例中,将时间不连续、采用相同多接入签名、长度不固定、在不同频域上的时频资源块定义为一个资源组。
如图7所示,资源组#1在时域上选取了不连续的资源,且分布在不同的频域上。UE#1选取资源组#1,UE#2选取资源组#2。UE#3选取资源组#3。UE分别将各自TB产生的RV放置在选定资源组的每个MAR上。
相对应地,基站将每个资源组的所有MAR上的冗余版本进行合并并译码,从而获取到UE发送给基站的上行信息。
图8示出了本申请又一实施例的MAR的示意图。在本实施例中,将时间不连续、采用不同多接入签名的、长度不固定且在不同频域上的时频资源块定义为一个资源组。
如图8所示,资源组#1在时域上选取了不连续的资源,且分布在不同的频域上。UE#1选取资源组#1。UE#2选取资源组#2。UE#3选取资源组#3。UE分别将各自的TB产生的RV放置在选定资源组的每个MAR上。
相对应地,在网络侧,基站将每个资源组上所有MAR的冗余版本进行合并后译码,得到UE发送给基站的上行信息。
图9示出了UE发送一个冗余版本的另一种方式。在本实施例中,UE每次发送一个传输块(Transport Block,TB),且一个TB仅有一个冗余版本。每个MAR上传送控制字。
图10示出了本申请又一实施例的MAR的示意图。如图10所示,UE选择不同数量、不同位置的MAR发送冗余版本,同时每个MAR上传送控制字。
可选地,作为一个实施例,控制字中携带UE ID和结束(End)位置指示信息。
相对应地,基站解调来自每个MAR的控制字。当检测到控制字的结束位置指示(End)为1时,将之前接收的所有与该控制字中携带的UE ID相同的MAR上承载的RV进行合
并译码,获取到UE发送的上行信息。
应理解,在本申请实施例中,仅将结束位置指示(End)为“1”时表明依次上行传输结束作为示例。显然,结束位置指示(End)信息可以设置为多种形式,例如,结束位置指示(End)也可以设置为“0”。本申请实施例对此不作任何限定。
可选地,作为一个实施例,控制字中携带UE ID和最大传输次数指示(Bundling Size)。
相对应地,当基站检测到来自同一个UE ID的MAR数目等于最大传输次数时,表明该UE ID所标识的UE的本次上行传输结束。
相对应地,基站将同一个UE ID的多个冗余版本进行合并译码,得到UE发送的上行信息。
可选地,作为一个实施例,控制字中携带UE ID、最大传输次数指示(Bundling Size)和结束位置指示(End)。
相对应地,当基站检测到来自同一UE ID的MAR数目等于最大传输次数或控制字的结束位置指示(End)为“1”时,表示该UE ID标识的UE的本次上行传输结束。基站将接收到的所有与该控制字中携带的UE ID相同的MAR上承载的RV进行合并译码,得到该UE发送的上行信息。
需要说明的是,以上各实施例中所述的资源组可以由UE自己选定。或者也可以由标准规定,或由UE和基站预先约定。UE将需要传输的一个或多个RV放置在资源中的每个MAR上发送给网络侧。
可选地,作为一个实施例,当UE发送给网络侧的至少一个冗余版本的版本号相同时,每个目标MAR上传输给网络侧的上行数据相同。
以下对冗余版本为多个的情况进行说明。
图11示出了本申请实施例的UE发送多个冗余版本的一种方式。在本实施例中,UE每次发送一个TB,该TB包括多个冗余版本。如图11所示,UE#1的TB包括4个冗余版本,分别为RV0、RV1、RV2和RV3。UE#2和UE#3各自的TB包括2个冗余版本,均为RV0和RV1。
图12示出了本申请又一实施例的MAR的示意图。在本实施例中,将时间不连续、采用不同多接入签名、长度不固定、在不同频域上的时频资源块定义为一个资源组。
如图12所示,资源组#1可以传送4个不同版本的RV,分别为RV0、RV1、RV2和RV3且分布在不同的时域和频域上。资源组#2可以传送2个版本的RV,为RV0和RV1。资源组#3仅传送一个冗余版本RV0。UE#1选取资源组#1,UE#2选取资源组#2,UE#3选取资源组#3。每个UE将各自TB产生的RV放置在选定资源组的每个MAR上。
相对应地,在网络侧,eNB将每个资源组的所有MAR上的冗余版本进行合并后译码,得到UE发送给eNB的上行信息。
图13示出了本申请实施例的UE发送多个冗余版本的另一种方式。在本实施例中,UE每次发送一个TB,且拥有多个RV。UE选择不同数量、不同位置的MAR进行发送。每个MAR上所携带的RV版本是固定的。每个MAR上传送控制字。其中,控制字中携带UE ID、最大传输次数指示(Bundling Size)和结束位置指示(End)。
相对应地,当基站检测到来自同一UE ID的MAR数目等于最大传输次数,或者控制字的结束位置指示(End)为“1”时,表示该UE的本次上行传输结束。
图14示出了本申请又一实施例的MAR的示意图。在本实施例中,UE每次发送一个TB,且拥有多个RV。UE选择不同数量、不同位置的MAR进行发送。UE在不同的MAR上放置该MAR规定的版本号的RV,并在所有MAR上放置控制字。
可选地,作为一个实施例,控制字中携带RV ID来指示该MAR上承载的RV的版本号。
相对应地,在网络侧,基站根据MAR和RV的预先对应规则来获得RV的版本号,并进行合并,具体地,针对相同版本号的RV,使用前后合并(Chase Combing,CC)的方法。针对不同版本号的RV,采用增量冗余(Incremental Redundancy,IR)合并的方法。
图15示出了本申请又一实施例的MAR的示意图。在本实施例中,eNB在解调每个MAR的控制字后,对来自每个UE的MAR进行计数,当计数超过一个门限时,对所有接收到的来自每个UE的RV分别进行合并译码。
如图15所示,假设eNB收到来自同一UE的2个MAR后开始合并译码。在时隙#2,UE#1选择的MAR资源与UE#2选择的MAR资源发生了碰撞。在时隙#3,eNB接收到来自UE#1的MAR数量达到门限。eNB将来自RV0和RV2合并后进行译码。如果译码成功,eNB向UE反馈ACK。如果译码失败,eNB则在收到RV3时,进行第二次合并译码。本实施例可以在部分控制字发送碰撞时,使eNB启动合并译码机制。
图16示出了本申请又一实施例的MAR的示意图。在本实施例中,eNB每隔一定时间(或者说,时段),对所有UE的冗余版本进行合并译码。如图16所示,假设eNB每隔两个时隙进行一次合并译码。在时隙2,eNB将接收到的来自UE#1的RV0译码,将来自UE#2的RV0译码,将来自UE#3的2个RV0进行合并后译码。如果译码成功,eNB向UE反馈ACK。如果译码失败,eNB在时隙#4进行第二次合并译码。本实施例可以在部分控制字发送碰撞时,使eNB启动合并译码机制。
图17示出了本申请实施例UE发送多个冗余版本的再一种方式。在本实施例中,UE每次发送多个TB,且拥有多个RV。UE选择不同数量、不同位置的MAR进行发送。同时每个MAR上传送控制字。与前述实施例不同的是,控制字中除了携带UE的ID、最大传输次数指示(Bundling Size)和结束位置指示(End),还携带有TB ID。TB ID用来区分该RV属于哪一个TB。
图18示出了本申请又一实施例的MAR的示意图。在本实施例中,相对应地,基站在进行合并译码时,需要合并UE ID相同且TB ID相同的冗余版本并译码,从而得到该UE发送的上行信息。
在上述各个实施例中,eNB在译码成功后向UE反馈ACK。UE接收到ACK后开始发送下一个TB的上行信息。如果上行信息发送失败,可以有以下两种方式对传输失败的上行信息重新进行发送。
(1)eNB向UE反馈NACK信息。
相对应地,UE在接收到NACK信息后进行重传。
(2)eNB不向UE反馈NACK信息。
相对应地,若UE在预设时段内没有接收到eNB反馈的ACK信息,则判断传输失败,并进行重传。重传时可以选择与之前相同的资源组或MAR。也可以重新选择不同的资源组或MAR。例如,在重传时使用数量更多、分集更高的MAR,以提高传输的可靠性。
可见,本申请实施例的免授权的传输上行信息的方法,UE通过频率分集或签名分集(或者,时间分集、频率分集和签名分集的任意组合)传输承载上行信息的冗余版本。与现有技术相比,在保证低时延的前提下,提高了传输上行信息时的灵活性。
220、UE在该多个目标MAR上向基站发送该至少一个冗余版本,基站接收终端设备在多个目标MAR上向基站发送该至少一个冗余版本。
根据前文所述,UE采用不同的方式确定发送冗余版本时使用的MAR(即,目标MAR)。相对应地,基站采用不同的方式接收UE发送冗余版本时使用的MAR,从而在目标MAR上接收到UE发送的冗余版本。
例如,在上述方式1中,UE根据预设规则选择MAR发送冗余版本。相对应地,基站根据预设规则能够获知UE发送冗余版本使用的MAR,从而在对应的MAR接收上接收冗余版本。
又例如,在方式2中,UE参考预设规则(即,预设的捆绑信息),并告知基站发送冗余版本时实际选择的MAR。相对应地,基站也能获知UE在哪些MAR资源上发送了冗余版本,并进行接收。
再例如,在方式3中,UE自主确定发送冗余版本时使用的MAR资源,并告知基站(例如,发送指示信息等)发送冗余版本时使用的MAR。相对应地,基站根据UE发送的指示信息目标MAR上接收冗余版本。
230、基站对该至少一个冗余版本进行合并,得到上行信息。
具体地,基站在接收到UE发送的冗余版本,并进行合并译码,得到UE发送的上行信息。
可选地,基站可以基于预设的MAR的数目,当接收到一个UE发送的MAR的数目达到预设数目时,对接收到的该UE的多个RV进行合并译码。本实施例可参考前文对图15所作的说明。为了简洁,此处不作赘述。
可选地,基站基于预设时段,对接收到的一个UE发送的冗余版本进行合并译码。本实施例可参考前文图16所作的说明。此处不作赘述。
需要说明的是,上述各实施例中资源组中所包括的MAR的数目仅作为示例,不应对本申请实施例的保护范围构成任何限定。
本申请实施例的免授权的传输上行信息的方法,UE通过使用频率分集或签名分集(或者,时间分集、频率分集和签名分集的任意组合)的MAR传输包括上行信息的冗余版本。在保证低时延的前提下,能够提高传输上行信息的灵活性。
