背景技术
在高级长期演进(Long Term Evolution–Advanced,LTE-A)的系统中,终端设备接收网络设备发送的指示传输第一传输块的第一调度信息,并根据该第一调度信息传输第一传输块。若终端设备向网络设备发送的第一传输块传输失败时,终端设备可以对第一传输块进行重传。具体地,网络设备可以发送指示重传第一传输块的第二调度信息,该第二调度信息中携带指示终端设备重传第一传输块的指示信息,终端设备根据该第二调度信息重传第一传输块,这样UE从接收到第一调度信息到根据该第一调度信息传输第一传输块的时间与接收到第二调度信息到根据该第二调度信息重传第一传输块的时间相同。

还应理解,在本申请实施例中,用户设备(User Equipment,UE)可称之为终端(Terminal)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal)等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,UE可称为接入终端、终端设备、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。UE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5G网络中的终端设备等。
本申请实施例中所使用的资源可以包括调度资源,也可以包括免调度资源,或者说,在本申请实施例中,通信系统中的各通信设备(例如,网络设备或终端设备)可以基于免调度传输方案使用资源进行通信,也可以基于调度方式使用资源进行通信,本申请实施例并未特别限定。
其中,调度传输可以是指:终端设备传输数据所使用资源需要由网络设备分配并通知给该终端设备。
即,在本申请实施例中,数据的传输可以是基于基站调度的,调度的基本时间单位是一个或多个时间资源,其中,时间资源的时间长度可以是一个或多个符号,也可以是一个或多个符号组,也可以是一个或多个迷你时隙、也可以是一个或多个时隙,也可以是一个或多个子帧,其中,符号可以是是一个子载波所在的频域为15kHz的符号,也可以是一个子载波所在的频域大于15kHz的通信系统的符号;时隙是一个子载波所在的频域为15kHz的时隙,或者,是一个子载波所在的频域大于15kHz的通信系统的时隙,长度可以小于0.5ms;迷你时隙是一个子载波所在的频域为60kHz的迷你时隙,或者,是一个子载波所在的频域其他的通信系统的时隙,长度可以小于时隙;子帧是一个子载波所在的频域为15kHz的子帧,或者是一个子载波所在的频域大于15kHz的通信系统的子帧,长度可以小于1ms,本实施例对此不作限定。如,一个子载波所在的频域大于15kHz的频域可以为30kHz,60kHz,120kHz,本实施例对此不作限定。
一个时域资源是指一个或多个时间资源;
一个频域资源可以是一个或多个子载波,也可以是一个或多个短物理资源块(Short Physical Resource Block,SPRB),也可以是一个或多个短物理资源块组(Short Physical Resource Block Group,SRBG),也可以是一个或多个短虚拟资源块(Short Virtul Resource Block,SVRB),也可以是一个或多个子载波组,也可以是一个或多个载波,也可以是一个或多个载波组。其中,SPRB和SVRB分别为不同含义的资源分配的基本单位。SPRB为频域上y个连续的子载波,时域上是一个传输时间长度的资源,传输时间长度可以从1个符号至x个符号中的任意符号数,x,y为正整数,在集中式资源分配时SVRB与SPRB的定义相同,在分布式资源分配时SVRB与SPRB有一定的对应关系。SPRB索引为SPRB索引,SVRB索引为SVRB索引,因此,该SPRB索引和该SVRB索引可以不同。SRBG可包括多个SPRB,SRBG中包括的SPRB的个数根据终端设备的带宽确定或者由网络设备指示得到。其中,SPRB索引可以为SPRB的编号,SRBG索引可以为SRBG的编号,SVRB索引可以为SVRB的编号,子载波索引可以为子载波的编号,子载波组索引可以为子载波组的编号。子载波组包括至少一个子载波,这里的一个子载波所在的频域可以是等于或大于15kHz的。
具体的调度流程是基站发送控制信道,该控制信道可以承载使用不同的下行控制信息(Downlink Control Information,DCI)格式的调度信息,该调度信息包括比如资源分配信息,调制编码方式等控制信息。终端设备在一个或多个时间资源中检测控制信道,并根据检测出的控制信道中承载的调度信息来进行下行数据信道的接收或上行数据信道的发送。
另外,近年来,研究人员针对时延敏感用户接入时间过长的问题提出了上行免调度(Grant-free)传输方案,所谓Grant Free是指不需要网络设备进行调度即可实现用户数据上行传输的方法,从而节省了上行接入过程中的时间。
在本申请实施例中,免调度传输可以理解为如下含义的任意一种含义,或,多种含义,或者多种含义中的部分技术特征的组合或其他类似含义:
免调度传输可以指:网络设备预先分配并告知终端设备多个传输资源;终端设备有上行数据传输需求时,从网络设备预先分配的多个传输资源中选择至少一个传输资源,使用所选择的传输资源发送上行数据;网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端设备发送的上行数据。所述检测可以是盲检测,也可能根据所述上行数据中某一个控制域进行检测,或者是其他方式进行检测。
免调度传输可以指:网络设备预先分配并告知终端设备多个传输资源,以使终端设备有上行数据传输需求时,从网络设备预先分配的多个传输资源中选择至少一个传输资源,使用所选择的传输资源发送上行数据。
免调度传输可以指:获取预先分配的多个传输资源的信息,在有上行数据传输需求时,从所述多个传输资源中选择至少一个传输资源,使用所选择的传输资源发送上行数据。获取的方式可以从网络设备获取或预先定义。
免调度传输可以指:不需要网络设备动态调度即可实现终端设备的上行数据传输的方法,所述动态调度可以是指网络设备为终端设备的每次上行数据传输通过信令来指示传输资源的一种调度方式。可选地,实现终端设备的上行数据传输可以理解为允许两个或两个以上终端设备的数据在相同的时频资源上进行上行数据传输。可选地,所述传输资源可以是终端设备接收所述信令的时刻以后的一个或多个时域资源的传输资源。
免调度传输可以指:终端设备在不需要网络设备授权的情况下进行上行数据传输。所述授权可以指终端设备发送上行调度请求给网络设备,网络设备接收调度请求后,向终端设备发送上行授权,其中所述上行授权指示分配给终端设备的上行传输资源。
免调度传输可以指:一种竞争传输方式,具体地可以指多个终端在预先分配的相同的时频资源上同时进行上行数据传输,而无需基站进行授权。
高层信令可以指:高层协议层发出的信令,高层协议层为物理层以上的每个协议层中的至少一个协议层。其中,高层协议层可以具体为以下协议层中的至少一个:媒体接入控制(Medium Access Control,MAC)层、无线链路控制(Radio Link Control,RLC)层、分组数据会聚协议(Packet Data Convergence Protocol,PDCP)层、(Radio Resource Control,无线资源控制RRC)层和非接入层(Non Access Stratum,NAS)层等。
所述的数据可以为业务数据或者高层信令数据。
在本申请实施例中,网络设备可以是GSM中的网络设备(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e-NodeB),还可以是新一代基站(new generation Node B,gNodeB),本申请实施例并不限定,但为描述方便,下述实施例将以ENB为例进行说明。
高级长期演进(Long Term Evolution–Advanced,LTE-A)系统中的时间域是通过无线帧(Radio-Frame)来进行标识的,每个无线帧由10个1毫秒(ms)长度的子帧(subframe)组成,每个子帧包括2个时隙(slot)。对于普通循环前缀(normal CP,Normal cyclic prefix),每个slot有7个符号(symbol)组成;对于长循环前缀(Extended cyclic prefix),每个slot有6个symbol组成。一个资源元素(resource element)在时间上是一个符号,在频率上是一个子载波。其中,上行符号称为单载波频分多址(Single Carrier Frequency Division Multiple Access,SC-FDMA)符号,下行符号称为正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。
需要说明的是,如果后续技术引入正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)的上行多址方式,则上行符号也可以称为OFDM符号。在本申请实施例中,上行符号和下行符号都可以简称为“符号”。传输时间间隔(transmission time interval,TTI)缩减为1个符号到0.5ms之间的数据包统称为sTTI数据包,或者,TTI不大于1ms的数据包称为sTTI数据包。
新无线技术(New radio,NR)系统中由多个OFDM符号或者SC-FDMA符号组成,但长度取决于不同的子载波间隔。例如,若子载波间隔为15kHz,则时隙长度为0.5ms;若子载波间隔大于为15kHz,则时隙小于0.5ms。NR系统可以包含多个不同的子载波间隔,1个子载波间隔被称为1个数字(numerology)。在不同的numerology下,符号的时间长度是不同的。
在第五代移动NR系统中存在多种不同的业务类型,而这多种业务类型分别对应不同的业务需求。例如,超可靠低延迟通信(Ultra-reliable and low latency communications,uRLLC)要求短时延高可靠性即在1ms中传输成功,增强的移动宽带(enhanced Mobile Broadband,eMBB)要求频谱效率但没有时延要求,海量物联网通信(massive Machine Type Communications,mMTC)要求周期性低功率发送等。
图1示出了UE发送上行数据信道的示意图。如图1所示,在LTE-A的系统中,终端 设备从没有调度资源到发送上行数据信道的步骤包括:
(1)UE等待发送调度请求(Scheduling Request,SR)的时间,如图1中的等待时段。
(2)UE在0号时段上发送SR,并在1号、2号和3号时段上等待网络设备接收该SR。这里为描述方便可以对时段进行编号,每个编号对应的时段长度为1ms。
(3)eNB接收该SR并生成调度信息,向UE发送调度信息,如图1所示,UE在4号时段接收到该调度信息。其中,eNB生成调度信息时并不知道UE实际想要发送的数据量。
(4)UE在5号、6号和7号时段为传输数据信道做准备操作,例如,组包、编码等。
(5)UE在8号时段上发送上行数据信道,并在上行数据信道中携带了UE的缓存器状态报告(Butter Status Report,BSR)信息和第一传输块,基站解调该上行数据信道得到BSR,根据BSR获知UE的数据量还没有发送完,则基站至少还会发送一个调度信息指示UE发送剩余的数据量,直到UE没有上行数据传输。
网络设备确定UE需要重传第一传输块时,可以在重传调度信息中携带指示UE重传第一传输块的重传指令,例如,在图2中的12号时段上的调度信息中携带重传第一传输块的重传指令,那么UE在12号时段之后开始重传包的组包,具体地可以是进行编码准备等。这样UE从接收到初传调度信息到初传的时间与接收到重传调度信息到重传的时间相同,即从4号时段到8号时段与从12号时段到16号时段的时间相同。因此,对于第一传输块是属于要求传输时延较短的URLLC业务,当第一传输块需要重传时,现有技术方案很难满足传输时延较短的要求。例如,要求在1ms的时间内传输正确的概率为1-10e -5的uRLLC业务来说,该方案很难满足。
图3示出了本申请一个实施例的数据发送的方法的示意性流程图。如图3所示,该方法的执行主体可以是终端设备,该方法包括:
301,终端设备接收第一调度信息,该第一调度信息用于指示第一资源,该第一资源是用于发送第一传输块的资源,该第一调度信息还用于指示部分或全部的该第一传输块可能被重传,或指示部分或全部的该第一传输块可能不被重传;
302,该终端设备根据该第一调度信息,在该第一资源上发送该第一传输块。
具体而言,终端设备接收第一调度信息,第一调度信息用于指示发送第一传输块的第一资源,进而终端设备可以在第一资源上传输该第一传输块,其中,第一资源包括第一时域资源和/或第一频域资源。此外,该第一调度信息还用于指示部分或全部的第一传输块是否可能被重传,即网络设备可以预测部分或全部第一传输块是否可能被重传,并通过第一调度信息指示给终端设备。若终端设备根据第一调度信息确定部分或全部的第一传输块可能被重传,那么在终端设备接收用于指示终端设备重传部分或全部的该第一传输块的第二调度信息或第三调度信息之前,终端设备可以确定是否需要为重传部分或全部的第一传输块做准备操作,进而缩短可以执行重传部分或全部的第一传输块的时间。也就是说,本申请实施例中,从第二调度信息或第三调度信息到重新传输部分或全部的第一传输块的时间小于从第一调度信息到传输第一传输块的时间,减少了重传时延。
应理解的是,网络设备可以预测该第一传输块的传输解调错误的概率,当解调错误的概率较高时,网络设备预测部分或全部的该第一传输块可能被重传;当解调错误的概率较 低时,网络设备预测部分或全部的该第一传输块可能不被重传。进一步的,当解调错误的概率等于或高于第一门限值,则认为解调错误概率较高;当解调错误的概率等于或低于第一门限值,则认为解调错误概率较低。
需要说明的是,第一传输块可以是一个传输块,也可以是多个传输块。
需要说明的是,终端设备根据高层信令、第一调度信息、第二调度信息、第三调度信息中的至少一个,确定重传部分的第一传输块或重传全部的第一传输块。该终端设备可以确定重传部分的第一传输块或重传全部的第一传输块。部分的第一传输块可以是至少一个码块,也可以是至少一个码块组,本申请不做限定。若确定重传部分的第一传输块时,相比传统方案减少了执行重传传输块的大小,提高了网络资源利用率。
需要说明的是,若终端设备接收的第一调度信息指示可能重传部分第一传输块,则该调度信息还可以指示重传的部分第一传输块在第一传输块中的具体位置;或者终端设备可以和网络设备提前约定重传的部分第一传输块的具体位置,本申请对此不进行限定。此外,为描述方便,在不作特别说明的情况下,下述实施例中重传第一传输块既可以是重传全部第一传输块,也可以是重传部分第一传输块。
应理解,终端设备为重传第一传输块做准备操作,准备操作包括一下至少一种:编码处理,配置高层配置信息,接收高层配置信息。终端设备进行编码处理,可以是预先设定的码率采用Turbo的并行级联卷积编码(Parallel Concatenated Convolutional Code,PCCC)或低密度奇偶校验码(Low Density Parity Check Code,LDPC)或卷积编码(Convolutional Code,CC)或咬尾卷积编码(Tail Biting Convolutional Code,TBCC)或极化码(Polar Code)的编码方式对至少一个编码块进行编码,也可以是预先设定的码率采用Turbo或PCCC或LDPC或CC或TBCC的编码方式对至少一个编码块编码之后,进行以下处理的一种或多种的组合:加扰,调制,层映射,预编码。
还应理解,为描述方便可以将第一传输块的一次传输表示为“初传”或“传输”,部分或全部的第一传输块的再一次传输表示为“重传”。
还应理解,第一传输块为至少承载数据信息和/或控制信息的基本单元,数据信息和/或控制信息可包含在一个传输块(或多个传输块)中,符合此特征的都可以作为第一传输块,本申请对第一传输块不进行限定。控制信息可以为上行控制信息(Uplink Control Information,UCI),上行控制信息可以包括以下至少一个:信道状态信息(Channel State Information,CSI),混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ),秩指示(Rank indicator,RI),预编码矩阵指示器(Precoding Matrix Indicators,PMI),信道质量指示器(Channel Quality Indicator,CQI)等。
因此,本申请实施例的数据发送的方法,通过接收用于指示发送第一传输块的第一资源以及指示部分或全部的该第一传输块可能被重传或可能不被重传的第一调度信息,并根据该第一调度信息在第一资源上发送该第一传输块,这样终端设备可以根据部分或全部的第一传输块可能被重传或可能不被重传提前确定是否需要为重传第一传输块做准备操作,进而在确定第一传输块可能被重传之后,在终端设备接收用于指示终端设备重传部分或全部的该第一传输块的第二调度信息或第三调度信息之前提前做准备操作,减少执行重传第一传输块的时间。
可选地,终端设备还可以接收第二调度信息,该第二调度信息用于指示终端设备重传 第一传输块,且第二调度信息用于指示第二资源,该第二资源为用于重传第一传输块的资源。这样终端设备根据该第二调度信息,可以在第二资源上重传第一传输块。当终端设备已知可能重传第一传输块,则可以在接收第二调度信息之前进行了准备操作,因此该第二资源包括的时域资源通常为早于按照传统方案确定的重传第一传输块的时域资源,相比传统方案减少了执行重传第一传输块的时间。
应理解,第二资源包括第二时域资源和/或第二频域资源。
可选地,网络设备可以预测第一传输块可能被重传,可能不被重传。网络设备通过第一调度信息指示重传第一传输块有关的指示信息给终端设备。

具体的,重传部分或全部的该第一传输块的调制方式可以为四相移键控(Quaternary Phase Shift Keying,QPSK),或正交幅度调制(Quadrature Amplitude Modulation,16QAM),或64QAM,或256QAM,或512QAM,或1024QAM,本发明不做限制。

具体的,重传部分或全部的该第一传输块的重传的功控命令字可以为指示一个载波的功控命令字,也可以是指示一个载波组的功控命令字,本发明不做限制。
具体的,重传部分或全部的该第一传输块的时间间隔可以是步骤301~步骤302中时间间隔的定义,这里不再赘述。
应理解的,第一调度信息还用于指示的信息可以是一个一种信息,也可以是多钟信息,也可以是多个同一种信息。
可选地,第一调度信息还用于指示第一传输块可能被重传,或第一传输块可能不被重传,这样终端设备根据第一调度信息确定第一传输块可能被重传,或者第一传输块可能不被重传。其中,该第一调度信息可以通过“显式”指示第一传输块可能被重传或可能不被重传,也可以通过“隐式”指示,本申请对此不进行限定。
可选地,第一调度信息可以包含第一指示信息,该第一指示信息“隐式”指示第一传输块可能被重传或可能不被重传。具体地,第一指示信息用于指示至少两个调制编码方式(Modulation and Coding Scheme,MCS)表格中的一个,该至少两个MCS表格中的第一表格用于指示部分或全部的该第一传输块可能被重传,该至少两个MCS表格中的第二表格用于指示部分或全部的该第一传输块可能不被重传。这样终端设备根据该第一指示信息确定该MCS表格是第一表格还是第二表格,进而能够确定该第一传输块可能被重传还是可能不被重传。也就是说,通过“隐式”指示第一传输块可能被重传还是可能不被重传,而不引入额外的指示信息域,这样能够使得减少第一调度信息承载的信息,从而降低网络中控制信令开销,提升网络传输效率。
例如,第一MCS表格可以是表1~表4中的一个或多个元素构成的。应理解的是,第二MCS表格中的MCS索引#X所对应的调制阶数、传输块大小索引中至少一个小于第一MCS表格中的MCS索引#X所对应的调制阶数、传输块大小索引。例如第一MCS表格中的MCS索引#11所对应的调制阶数为4、传输块大小索引为10,那么第二MCS表格中的MCS索引#11所对应的调制阶数为2、传输块大小索引为10。再例如第一MCS表格中的MCS索引#11所对应的调制阶数为4、传输块大小索引为10,那么第二MCS表格中的MCS索引#11所对应的调制阶数为2、传输块大小索引为4。再例如第一MCS表格中的MCS索引#11所对应的调制阶数为4、传输块大小索引为10,那么第二MCS表格中的MCS索引#11所对应的调制阶数为4、传输块大小索引为2。
应理解的,本申请实施例中是指具有第二MCS表格中的MCS索引#X所对应的调制阶数、传输块大小索引中至少一个小于第一MCS表格中的MCS索引#X所对应的调制阶数、传输块大小索引的特征的第一MCS表格和第二MCS表格。

可选地,第一调度信息可以包含第二指示信息,该第二指示信息“显式”指示第一传输块可能被重传或可能不被重传。具体地,第二指示信息可以为至少一个比特,该至少一个比特的第一比特状态值用于指示部分或全部的该第一传输块可能被重传,该至少一个比特的第二比特状态值用于指示部分或全部的该第一传输块可能不被重传。也就是说,通过“显式”指示第一传输块可能被重传还是可能不被重传,引入专用的指示信息域,使得网络设备可以灵活指示是否部分或全部的该第一传输块可能被重传。
例如,第二指示信息占用一个比特位,若该比特位的状态值为1指示第一传输块可能被重传;若该比特位的状态值为0指示第一传输块可能不被重传,或者也可以进行相反的设定,本申请对此不进行限定。
应理解,第二指示信息占用的比特位可以是专门为第二指示信息分配的,也可以是复用其他信息的比特位,本申请对此不进行限定。
可选地,第一调度信息可以包含第三指示信息,该第三指示信息“隐式”指示第一传输块可能被重传或可能不被重传。具体地,第三指示信息用于指示至少两个时间间隔中的一个,该至少两个时间间隔中的第一时间间隔用于指示部分或全部的该第一传输块可能被重传,该至少两个时间间隔中的第二时间间隔用于指示部分或全部的该第一传输块可能不被重传。也就是说,通过“隐式”指示第一传输块可能被重传还是可能不被重传,能够节省网络设备的功耗。
可选地,终端设备接收高层信令,该高层信令包括第一阈值,终端设备可以根据该第 一阈值与第三指示信息指示的时间间隔的大小关系确定第三指示信息指示的第一时间间隔和/或第二时间间隔。
具体地,可以将第三指示信息指示的时间间隔大于第一阈值的时间间隔设定为第一时间间隔,将第三指示信息指示的时间间隔小于或等于第一阈值的时间间隔设定为第二时间间隔,或者也可以进行相反的设定,本申请对此不进行限定。
可选地,该第一阈值还可以是终端设备与网络设备预先设定的;该第一时间间隔或第二时间间隔可以是终端设备根据该第一阈值与第三指示信息指示的时间间隔的大小关系确定的,本申请对此不进行限定。
具体而言,该至少两个时间间隔中的时间间隔包括以下中至少一个:
接收第一调度信息的时域资源到该第一资源包含的第一时域资源的时间间隔。例如第一调度信息的时域资源为时域资源#A,该第一资源包含的第一时域资源为时域资源#B那么时间间隔为时域资源#A到时域资源#B,假设时域资源#A和时域资源#B的时域资源长度均为第一时间长度,那么时间间隔为(B-A)个第一时间长度的时间,例如,时间间隔可以是从时域资源#A的结束时刻到时域资源#B的起始时刻,也可以是时域资源#A的索引到时域资源#B的索引;
接收第一调度信息的时域资源到可能接收第二调度信息的时域资源的时间间隔,或,接收第一调度信息的时域资源到可能接收第三调度信息的时域资源的时间间隔。例如第一调度信息的时域资源为时域资源#A,可能接收第二调度信息的时域资源为时域资源#C,那么时间间隔为时域资源#A到时域资源#C,假设时域资源#A和时域资源#C的时域资源长度均为第一时间长度,那么时间间隔为(C-A)个第一时间长度的时间,例如,时间间隔可以是从时域资源#A的结束时刻到时域资源#C的起始时刻,也可以是时域资源#A的索引到时域资源#C的索引;
接收第一调度信息的时域资源到可能重传部分或全部的该第一传输块的时域资源的时间间隔,或,接收第一调度信息的时域资源到该第二资源的时域资源的时间间隔,或,接收第一调度信息的时域资源到该第三资源的时域资源的时间间隔。例如第一调度信息的时域资源为时域资源#A,可能重传部分或全部的该第一传输块的时域资源为时域资源#D,那么时间间隔为时域资源#A到时域资源#D,假设时域资源#A和时域资源#D的时域资源长度均为第一时间长度,那么时间间隔为(D-A)个第一时间长度的时间,例如,时间间隔可以是从时域资源#A的结束时刻到时域资源#D的起始时刻,也可以是时域资源#A的索引到时域资源#D的索引;
该第一资源包含的第一时域资源到可能重传部分或全部的该第一传输块的时域资源的时间间隔,该第一资源包含的第一时域资源到该第二资源包含的第二时间资源的时间间隔。例如该第一资源包含的第一时域资源为时域资源#B,可能重传部分或全部的该第一传输块的时域资源#D,那么时间间隔为时域资源#B到时域资源#D,假设时域资源#B和时域资源#D的时域资源长度均为第一时间长度,那么时间间隔为(D-B)个第一时间长度的时间,例如,时间间隔可以是从时域资源#B的结束时刻到时域资源#D的起始时刻,也可以是时域资源#B的索引到时域资源#D的索引;
该第一资源包含的第一时域资源到可能接收第二调度信息的时域资源的时间间隔,该第一资源包含的第一时域资源到可能接收第三调度信息的时域资源的时间间隔。例如该第 一资源包含的第一时域资源为时域资源#B,可能接收第二调度信息的时域资源为时域资源#C,那么时间间隔为时域资源#B到时域资源#C,假设时域资源#B和时域资源#C的时域资源长度均为第一时间长度,那么时间间隔为(C-B)个第一时间长度的时间,例如,时间间隔可以是从时域资源#B的结束时刻到时域资源#C的起始时刻,也可以是时域资源#B的索引到时域资源#C的索引;
接收第二调度信息的时域资源到可能重传部分或全部的该第一传输块的时域资源的时间间隔,接收第二调度信息的时域资源到该第二资源的时域资源的时间间隔,接收第三调度信息的时域资源到可能重传部分或全部的该第一传输块的时域资源的时间间隔,接收第三调度信息的时域资源到该第三资源的时域资源的时间间隔。例如接收第二调度信息的时域资源为时域资源#C,可能重传部分或全部的该第一传输块的时域资源#D,那么时间间隔为时域资源#C到时域资源#D,假设时域资源#C和时域资源#D的时域资源长度均为第一时间长度,那么时间间隔为(D-C)个第一时间长度的时间,例如,时间间隔可以是从时域资源#C的结束时刻到时域资源#D的起始时刻,也可以是时域资源#C的索引到时域资源#D的索引;
其中,可能接收第二调度信息的时域资源,可能接收第三调度信息的时域资源,可能重传部分或全部的该第一传输块的时域资源可以是预定义的或高层信令配置的时域资源。
具体而言,至少两个时间间隔中的时间间隔还可以是该第一时域资源、该第二时域资源、该第三时域资源、第四时域资源和第五时域资源中任意两项时域资源之间的时间间隔。而第一时域资源为第一资源包括的时域资源,第二时域资源为第二资源包括的时域资源,第三时域资源为第三资源包括的时域资源,第四时域资源为终端设备接收第一调度信息的时域资源,第五时域资源为终端设备接收第二调度信息或接收第三调度信息的时域资源。此外,两个时域资源之间的时间间隔为时间在前的时域资源的结束时刻到时间在后的时域资源的起始时刻,例如,第四时域资源与第五时域资源的时间间隔为第四时域资源的结束时刻到第五时域资源的起始时刻,其中,接收第一调度信息的第四时域资源早于接收第二调度信息的第五时域资源。这样终端设备能够根据时间间隔的长短确定第一传输块可能被重传或可能不被重传。
可选的,第一调度信息包含第四指示信息,第四指示信息用于指示至少两个调制编码方式MCS值中的一个,该至少两个MCS值中的第一MCS值用于指示部分或全部的该第一传输块可能被重传,该至少两个MCS值中的第二MCS值用于指示部分或全部的该第一传输块可能不被重传。
终端设备根据该第四指示信息确定该MCS值是第一MCS值还是第二MCS值,进而能够确定该部分或全部的第一传输块可能被重传还是可能不被重传,通过“隐式”方式指示部分或全部的第一传输块可能被重传还是可能不被重传,而不引入额外的指示信息域,这样能够使得减少第一调度信息承载的信息,从而降低网络中控制信令开销,提升网络传输效率。
可选地,终端设备根据第一调度信息确定第一传输块可能被重传,则终端设备执行准备操作,这样终端设备可以使用较短的时间重新传输第一传输块,从而减少了重传第一传输块的时延。
需要说明的是,若终端设备根据第一调度信息确定第一传输块可能不被重传,则终端 设备不需要进行准备操作。
应理解,该第一调度信息还可以指示第一传输块可能被重传的次数,即终端设备可以多次提前为第一传输块进行准备操作,本申请对此不进行限定。
可选地,作为一个实施例,在第一调度信息可以指示重传第一传输块的第三时域资源时,终端设备可以在距离第三时域资源的时间达到第二阈值时,启动重传第一传输块的准备操作,这样可以避免启动太晚对重传第一传输块造成影响,也可以避免太早启动准备操作,节省终端设备的功耗。
需要说明的是,该第二阈值可以是终端设备根据完成重传第一传输块的准备操作所需的时间确定的,也可以是的高层信令通知的,也可以是预先定义的。例如第二阈值为一个或多个子帧,也可以是一个或多个时隙,也可以是一个或多个符号,也可以是一个或多个时域资源,本发明不做限定。
具体而言,时域资源还可以是距离本次调度信息或上行传输的间隔的n个时间资源的单位。频域资源还可以是资源分配、资源分配类型和子载波间隔等中的一个。调制编码具体可以是调制编码表格、调制方式、编码方式、编码码率、调制编码索引值等中的一个。编码码率可以是1/2、1/3或1/6等。参考信号信息可以包括循环移位、位置和结构等。
应理解,重传第一传输块的传输方式可以与初传第一传输块的传输方式相同,也可以不同;在重传部分第一传输块或全部第一传输块时,采用的传输方式可以相同,也可以不同;本申请实施例对此不进行限定。传输方式可以是指调制、编码、传输模式、传输制式(OFDM or IFDMA)、频域资源中的至少一个。
因此,本申请实施例的数据发送的方法,通过接收用于指示发送第一传输块的第一资源以及指示部分或全部的该第一传输块可能被重传或可能不被重传的第一调度信息,并根据该第一调度信息在第一资源上发送该第一传输块,这样终端设备可以根据部分或全部的第一传输块可能被重传或可能不被重传提前确定是否需要为重传第一传输块做准备操作,进而在确定第一传输块可能被重传之后,在终端设备接收用于指示终端设备重传部分或全部的该第一传输块的第二调度信息或第三调度信息之前提前做准备操作,减少执行重传第一传输块的时间。
图4示出了本申请另一个实施例的数据发送的方法的示意性流程图。本实施例中的各种术语的含义与前述各实施例相同。如图4所示,该方法包括:
401,终端设备接收第一调度信息,该第一调度信息用于指示第一资源,该第一资源是用于发送第一传输块的资源,该第一调度信息还用于指示概率值,其中,该概率值为网络设备在该第一资源上接收该第一传输块的误块率或该网络设备在该第一资源上接收该第一传输块的成功概率。相应地,网络设备发送该第一调度信息;
402,该终端设备根据该第一调度信息,在该第一资源上发送该第一传输块。
终端设备接收用于指示发送第一传输块的第一资源的第一调度信息,该第一调度信息还用于指示概率值,该概率值可以是网络设备根据终端设备信道质量和/或调制编码方式预测的接收第一传输块的误块率或网络设备根据终端设备信道质量和/或调制编码方式预测的接收该第一传输块的成功概率。这样终端设备可以根据概率值,确定是否需要为重传全部或部分的第一传输块做准备操作,进而可以缩短执行重传部分或全部的第一传输块的时间,减少了重传时延。
终端设备在第一调度信息指示的第一资源上发送第一传输块。相应地,网络设备在第一资源上接收该第一传输块。
应理解的,第一调度信息还用于指示概率值可以是第一调度信息还用于指示该第一传输块的概率值,也可以是第一调度信息还用于指示在该第一资源上发送的该第一传输块的概率值。
应理解,误块率具体可以是网络设备解调第一传输块错误的概率。误块率可以是BLER(Block Error Rate),也可以是rBLER(residual Block Error Rate),本发明不做限定。
例如,概率值可以是第一传输块的误块率,误块率为大于0的有理数,例如0.1,0.01,0.001,0.0001,0.00001,0.000001,0.0000001,0.00000001,0.000000001,0.0000000001,0.02,0.04,0.05,0.002,0.0025等。概率值可以是第一传输块的成功概率,该成功概率为大于0的有理数,具体的可以是1-BLER,也可以是1-rBLER,例如0.9,0.99,0.99999,0.999999999。
还应理解,第一传输块可以是一个传输块,也可以是多个传输块。
可选地,作为一个实施例,该概率值可以是第一概率值或第二概率值,第一概率值指示重传全部或部分第一传输块,第二概率值指示不重传全部或部分第一传输块。
具体而言,该概率值为第一概率值或第二概率值可以是由终端设备确定的,也可以是由网络设备确定的。
例如,网络设备可以设定第一门限阈值,当预测接收第一传输块的成功概率小于该第一门限阈值,则认为解调错误概率高,可以指示终端设备重传全部或部分第一传输块,即表示为第一概率值;当预测接收第一传输块的成功概率大于该第一门限阈值,则认为解调错误概率低,可以指示终端设备重传全部或部分第一传输块,即表示为第二概率值。相反地,网络设备可以设定第二门限阈值,若预测接收第一传输块的误块率大于该第二门限阈值,则认为解调错误概率高,可以指示终端设备重传全部或部分第一传输块,即表示为第一概率值;当预测接收第一传输块的成功概率小于该第二门限阈值,则认为解调错误概率低,可以指示终端设备重传全部或部分第一传输块,即表示为第二概率值。
应理解,第一门限阈值和第二门限阈值可以相同,也可以不同。第一门限阈值为大于0的有理数,例如0.99999,也可以为0.99,也可以是0.999,本发明不做限定。第二门限阈值大于0的有理数,例如,可为0.00001,也可以是0.01,也可以为0.001,本发明不做限定。第一门限阈值和第二门限阈值也可以是预先定义的,也可以是网络设备设定,并通过高层信令通知给终端设备的。
需要说明的是,若第一概率值指示重传部分第一传输块,则该第一调度信息还可以指示重传的部分第一传输块在第一传输块中的具体位置;或者终端设备可以和网络设备提前约定重传的部分第一传输块的具体位置,本申请对此不进行限定。此外,为描述方便,在不作特别说明的情况下,下述实施例中重传第一传输块既可以是重传全部第一传输块,也可以是重传部分第一传输块。
应理解,部分的第一传输块可以是至少一个码块,也可以是至少一个码块组,本申请不做限定。若确定重传部分的第一传输块时,相比传统方案减少了执行重传传输块的大小,提高了网络资源利用率。
可选地,作为另一个实施例,该概率值还可以是第一概率值或第二概率值,该第一概 率值指示全部或部分该第一传输块可能被重传,该第二概率值指示部分或全部的该第一传输块可能不被重传。
具体而言,该概率值是第一概率值还是第二概率值的判定方法可以与上述实施例相同,为避免重复在此不再赘述。
可选地,终端设备在确定第一调度信息还用于指示的概率值为第一概率值时,进行重传全部或部分的第一传输块的准备操作。
具体而言,终端设备在确定第一调度信息用于指示第一概率值时,即第一调度信息用于指示终端设备重传全部或部分第一传输块,或用于指示终端设备可能重传全部或部分第一传输块,则终端设备进行重传全部或部分第一传输块的准备操作,进而缩短可以执行重传部分或全部的第一传输块的时间,减少了重传时延。
