具体实施方式
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清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如,部件可以是但不限于,在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示,在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中,部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外,这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据,例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
本发明实施例的方案可以应用于现有的蜂窝通信系统,如全球移动通讯 (英文全称可以为:Global System for Mobile Communication,英文简称可以为:GSM),宽带码分多址(英文全称可以为:Wideband Code Division Multiple Access,英文简称可以为:WCDMA),长期演进(英文全称可以为:Long Term Evolution,英文简称可以为:LTE)等系统中,所支持的通信主要是针对语音和数据通信的。通常来说,一个传统基站支持的连接数有限,也易于实现。
下一代移动通信系统将不仅支持传统的通信,还将支持M2M(英文全称可以为:Machine to Machine)通信,或者叫做MTC(英文全称可以为:Machine Type Communication)通信。根据预测,到2020年,连接在网络上的MTC设备将会达到500到1000亿,这将远超现在的连接数。对M2M类业务,由于其业务种类千差万别,对网络需求存在很大差异。大致来说,会存在如下几种需求:
可靠传输,但对时延不敏感;
低延迟,高可靠传输。
对可靠传输,而对时延不敏感业务,较容易处理。但是,对低延迟、高可靠传输类的业务,不仅要求传输时延短,而且要求可靠,比如V2V(英文全称为:Vehicle to Vehicle)业务。如果传输不可靠,会导致重传而造成传输时延过大,不能满足要求。
由于大量连接的存在,使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入终端设备以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。根据本发明实施例的方案能够有效解决上述资源消耗问题。
可选地,该网络设备为基站,该终端设备为用户设备。
本发明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(UE,User Equipment)用户设备、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。终端设备可以是WLAN(Wireless Local Area Networks,无线局域网)中的ST(STAION,站点),可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol,会话启动协议)电话、WLL(Wireless Local Loop,无线本地环路)站、PDA(Personal Digital Assistant,个人数字处理)、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网络中的终端设备或者未来演进的 PLMN网络中的终端设备等。
此外,本发明结合网络设备描述了各个实施例。网络设备可以是网络设备等用于与移动设备通信的设备,网络设备可以是WLAN(Wireless Local Area Networks,无线局域网)中的AP(ACCESS POINT,接入点),GSM或CDMA(Code Division Multiple Access,码分多址)中的BTS(Base Transceiver Station,基站),也可以是WCDMA中的NB(NodeB,基站),还可以是LTE(Long Term Evolution,长期演进)中的eNB或eNodeB(Evolutional Node B,演进型基站),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网络中的终端设备或者未来演进的PLMN网络中的网络设备等。
此外,本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,CD(Compact Disk,压缩盘)、DVD(Digital Versatile Disk,数字通用盘)等),智能卡和闪存器件(例如,EPROM(Erasable Programmable Read-Only Memory,可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是使用本发明的传输信息的通信系统的示意图。如图1所示,该通信系统100包括网络设备102,网络设备102可包括多个天线例如,天线104、106、108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(FDD,Frequency Division Duplex)系统中,例如,前向链路118可利用与反向链路120所使用的不同频带,前向链路124可利用与反向链路126所使用的不同频带。
再例如,在时分双工(TDD,Time Division Duplex)系统和全双工(Full Duplex)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如,可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外,与网络设备通过单个天线向它所有的终端设备发送信号的方式相比,在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。
此外,该通信系统100可以是公共陆地移动网络(英文全称可以为:Public Land Mobile Network,英文简称可以为:PLMN)网络或者D2D网络或者M2M网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他网络设备,图1中未予以画出。图2示出了从发送端设备描述的根据本发明一实施例的传输信息的方法200的示意性流程图。如图2所示,该方法200包括:
S210,网络设备根据终端设备在进行上行传输时所使用的时频资源和码域资源,确定与该终端设备相对应的反馈时频资源;
S220,通过该反馈时频资源向该终端设备发送针对该上行传输的反馈结果的指示信息。
其中,网络设备向该终端设备发送信息的方式可以是广播方式,或者是定向方式,或者是其他方式。
可选地,该上行传输为免授权传输,该免授权传输为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,并使用所选择的传输资源发送上行数据。
具体地说,近年来,研究人员针对海量用户接入引发的一系列问题提出了上行免授权(Grant-free)传输方案,所谓Grant Free是指不需要网络设备动态调度即可实现用户数据上行传输的方法。
本发明实施例的方法200可以用于针对基于Grant Free(即,使用的免授权传输资源进行)方案的上行传输的反馈过程,例如,HARQ中ACK或NACK的反馈过程。
应理解,以上列举的HARQ中ACK或NACK的反馈过程仅为反馈的示例性说明,本发明并不限定于此,其他能够反馈方式均落入本发明的保护范围内,例如,还可以列举自动重传请求(ARQ,Automatic Repeat-reQuest)等技术中的反馈。
以下,为了便于理解和说明,以将本发明实施例的方法应用于HARQ时的处理过程为例,进行详细说明。
为了解决未来网络大量的MTC类业务,以及满足低时延、高可靠的业务传输,本专利提出了免授权传输的一种方案。免授权传输英文可以表示为Grant Free。这里的免授权传输可以针对的是上行数据传输。免授权传输可以理解为如下含义的任一一种含义,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:
免授权传输可以指: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。

免授权传输可以指: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。
免授权传输可以指: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。
所述的数据可以为包括业务数据或者信令数据。
所述盲检测可以理解为在不预知是否有数据到达的情况下,对可能到达的数据进行的检测。所述盲检测也可以理解为没有显式的信令指示下的检测。
所述传输资源可以包括但不限于如下资源的一种或多种的组合:
α-时域资源,如无线帧、子帧、符号等;
β-频域资源,如子载波、资源块等;

δ-上行导频资源。
如上的传输资源可以根据包括但不限于如下的控制机制进行的传输:
a-上行功率控制,如上行发送功率上限控制等
b-调制编码方式设置,如传输块大小、码率、调制阶数设置等;
c-重传机制,如HARQ机制等。
竞争传输单元(英文全称可以为:Contention Transmission Unit,英文缩写可以为:CTU)可以为免授权传输的基本传输资源。CTU可以指时间、频率、码域相结合的传输资源,或者,可以指时间、频率、导频相结合的传输,或者,可以指时间、频率、码域、导频相结合的传输资源。
CTU所属的接入区域可以指CTU对应的时频区域。
专利号PCT/CN2014/073084,申请名称为“System and Method for Uplink Grant-free Transmission Scheme”的专利申请给出了一种上行免授权传输的技术方案。PCT/CN2014/073084申请介绍可以将无线资源划分为各种CTU,UE被映射到某个CTU。每个CTU可以被分配一组码,所分配的一组码可以是一组CDMA码,也可以是SCMA码本集或LDS序列组或签名(signature)组等。每一个码可以对应一组导频。用户可以选择一个码以及与该码对应的导频组中的一个导频进行上行传输。PCT/CN2014/073084申请内容也可以理解为通过引用作为本发明实施例内容的一部分,不再赘述。
在适用该方法200的通信系统中,可以具有多个(两个或两个以上)终端设备,各终端设备根据Grant Free方案,自主选择免授权传输资源向网络设备发送上行数据。并且,各导频和各传输资源(或者说,免授权资源)可以具有一一对应关系,网络设备可以根据各终端设备所选择的导频,获知各终端设备所选用的传输资源。
不失一般性,以下,为了便于理解和区分,以针对多个终端设备中的终端设备(以下,为了便于理解和区分,记做:终端设备#A)的反馈过程为例,进行对该方法200进行详细说明。
在S210,网络设备可以根据该终端设备#A所使用的传输资源(以下,为了便于理解和区分,记做:传输资源#A),基于预设的用于指示各传输资源与下行时频资源中的各反馈时频资源之间的对应关系的映射规则(例如, 公式或表项等,以下,为了便于理解和区分,记做:映射规则#A),确定与该免授权传输资源#A相对应的反馈时频资源(即,反馈时频资源,以下,为了便于理解和区分,记做:反馈时频资源#A)。
类似地,终端设备#A可以根据该映射规则#A,确定反馈时频资源#A。
通过使网络设备和终端设备使用相同的映射规则,能够使双方所确定的反馈时频资源相同,从而能够确保反馈的可靠性。
可选地,该下行时频资源包括免授权反馈区域和授权反馈区域,该免授权反馈区域用于针对该免授权传输的反馈,该授权反馈区域用于针对授权传输的反馈。
该网络设备根据终端设备在进行上行传输时所使用的时频资源和码域资源,确定与该终端设备相对应的反馈时频资源,包括:
网络设备根据终端设备在进行上行传输时所使用的时频资源和码域资源,从该免授权反馈区域中,确定与该终端设备相对应的反馈时频资源。
具体地说,图3示出了本发明实施例的下行时频资源的分布方式的一例,如图3所示,下行时频资源包括用于对授权传输进行反馈的授权反馈区域、用于对免授权传输进行反馈的免授权反馈区域以及用于承载下行数据的下行传输区域,在本发明实施例中,可以从该免授权反馈区域确定反馈时频资源,以进行针对上述免授权传输的反馈。
另外,在本发明实施例中,采用授权区域中的时频资源进行针对授权上行传输的反馈的过程和方法可以与现有技术相似,并且,通过下行传输区域中的时频资源进行下行传输的过程和方法可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
应理解,图3所示的下行时频资源的分布方式仅为实例性说明,本发明并不限定于此,例如,在图3中示出了免授权反馈区域位于授权反馈区域和下行传输区域之间的方式,但本发明并不限定于此,免授权反馈区域也可以位于授权反馈区域之前而处于下行时频资源的最前端,或者,免授权反馈区域也可以下行传输区域之后而处于下行时频资源的最末端。
根据本发明实施例的传输信息的方法,通过使下行时频资源包括免授权反馈区域和授权反馈区域,并使该免授权反馈区域用于针对该免授权传输的反馈,该授权反馈区域用于针对授权传输的反馈,能够同时应对针对授权上行传输的反馈以及免授权上行传输的反馈,能够提高本发明实施例的传输信 息的方法的实用性和灵活性。
可选地,该网络设备根据终端设备在进行上行传输时所使用的时频资源和码域资源,确定与该终端设备相对应的反馈时频资源,包括:
网络设备根据终端设备在进行上行传输时所使用的时频资源和数据部分所使用的码域资源,确定与该终端设备相对应的反馈时频资源。
具体地说,在本发明实施例中,上行传输(包括授权传输和免授权传输)可以包括数据部分和导频部分,在上行传输过程中,该导频部分可以用于进行信道估计等,该数据部分可以承载上行传输所要传输的数据,在本发明实施例中,上述进行上行传输时所使用的传输资源可以为上行传输时数据部分所使用的传输资源。
另外,如上所述,传输资源可以包括时域资源、频域资源、空域资源、码域资源等,网络设备或终端设备可以使用其中的时频资源和码域资源来确定反馈时频资源。
可选地,该终端设备在进行上行传输时所使用的时频资源为该终端设备在上行传输时所使用的竞争传输单元CTU对应的时频资源。
具体地说,目前的Grant-free方案中定义了CTU作为信息的承载单元,用户设备按照一定准则将数据映射在CTU上,完成上行数据传输,基站侧对CTU资源进行盲检,恢复出承载的用户数据。
图4示出了可用带宽被分成四个竞争接入区域(也成为CTU接入区域)的时频区域,即,CTU接入区域(CTU access region)310、320、330和340,即。每个CTU access region可以占用预定数量的资源块(Resource Block),例如,在图4的实施例中,CTU access region 310包括四个RB:RB1、RB2、RB3和RB4。本发明的实施例并不限于此,例如,不同的竞争接入区域可以包括不同数目的RB。在图4中,每个CTU access region能够支持36个UE竞争该CTU access region中定义的36个CTU,每个CTU是时域资源、频域资源、码域资源和导频的结合。码域资源包括CDMA码或SCMA码或LDS序列或其它签名(signature)等。每个竞争接入区域占用一个时频资源区,每个时频资源区支持6个码域资源(S1-S6),并且每个码域资源映射到6个导频,从而生成总共36个导频(P1-P36)。网络设备可以使用导频或码域资源解相关器来检测或解码各个UE在CTU上发送的信号。
UE进入源网络设备的覆盖区时,可以接收到网络设备发送的高层信令。 该高层信令可以携带CTU接入区域定义(CTU access region definition)、CTU的总数、默认映射规则等等。可替代地,UE也可预先配置默认映射规则。UE可以确定一个合适的CTU以在该CTU上进行免授权传输。当不同的UE在相同的CTU进行免授权传输时,即竞争相同的CTU时,会出现冲突。UE可以根据网络设备的指示确定是否存在冲突。例如,可以采用异步HARQ方法解决冲突引起的问题。然而,如果冲突的次数超过预定的阈值,则可以请求网络设备重新映射CTU。网络设备将重新映射后的CTU的信息发送给UE,以便UE在重新映射后的CTU上进行免授权传输。
应理解,为了描述方便,图4示出了四个CTU access region,本发明的实施例并不限于此,可以根据需要定义更多或更少的CTU access region。。
因此,在本发明实施例中,可以根据上述CTU access region来确定反馈资源。
即,上述映射规则#A可以记录有各CTU access region与各反馈时频资源之间的映射关系。从而,网络设备或终端设备#A可以根据该终端设备#A在免授权传输时使用的上行CTU access region,确定相同的用于进行针对该终端设备#A的反馈的反馈时频资源(例如,时频资源块)。
再例如,在本发明实施例中,可以根据用于免授权传输的码域资源(例如,码本)来确定反馈资源。
即,上述映射规则#A可以记录有各码域资源与各反馈时频资源之间的映射关系。从而,网络设备或终端设备#A可以根据该终端设备#A在上行传输时使用的码本,确定相同的用于进行针对该终端设备#A的反馈的反馈时频资源。
再例如,在本发明实施例中,可以根据用于免授权传输的导频资源来确定反馈资源。
即,上述映射规则#A可以记录有各导频与各反馈时频资源之间的映射关系。从而,网络设备或终端设备#A可以根据该终端设备#A在上行传输时使用的导频,确定相同的用于进行针对该终端设备#A的反馈的反馈时频资源。
再例如,在本发明实施例中,可以根据用于免授权传输的空域资源(例如,所使用的天线)来确定反馈资源。
即,上述映射规则#A可以记录有各空域资源与各反馈时频资源之间的 映射关系。从而,网络设备或终端设备#A可以根据该终端设备#A在上行传输时使用的空域资源,确定相同的用于进行针对该终端设备#A的反馈的反馈时频资源(即,反馈时频资源)。
在确定了上述反馈时频资源之后,在S220,网络设备可以在该反馈时频资源上发送针对终端设备#A的反馈信息(即,上行传输的反馈结果的指示信息的一例,例如,ACK信息或NACK信息),并且,终端设备#A在该反馈时频资源上接收上述反馈信息。
从而,能够在无需网络设备的资源调度的情况下完成上行传输的反馈过程。
可选地,该上行传输的反馈结果的指示信息包括该终端设备所对应的符号序列,该终端设备所对应的符号序列属于包括至少两个彼此正交的符号序列的符号序列集合,该终端设备所对应的符号序列用于指示该上行传输的反馈结果为确认ACK,或该终端设备所对应的符号序列用于指示该上行传输的反馈结果为非确认NACK。
具体地说,在本发明实施例中,可以预先设定一个或多个符号序列集合,并且,每个符号序列集合中包括多个彼此正交的符号序列。
可选地,该符号序列包括沃尔什wash序列或古德恩Golden序列。
具体地说,在本发明实施例中,可以采用例如wash序列或Golden序列作为正交的符号序列,应理解,以上列举的作为符号序列的具体实例仅为实例性说明,本发明并不限定于此,本发明的符号序列可以通过任意能够生成正交序列的方法生成。
可选地,该符号序列集合中的符号序列和导频具有一一对应关系,以及
该方法还包括:
根据该终端设备在进行免授权传输时使用的导频,确定该终端设备所对应的符号序列。
具体地说,在本发明实施例中,可以使多个导频与多个符号序列一一对应,从而,在终端设备#A选择导频#A后,,网络设备或终端设备#A可以确定与该导频#A相对应的符号序列#A,作为该终端设备#A所对应的符号序列。
应理解,以上列举的使终端设备与符号序列之间的一一映射关系的具体实现方式,仅为示例性说明本发明并不限定于此,例如,也可以以终端设备的设备标识作为媒介,即,使多个终端设备标识与多个符号序列一一对应, 从而,网络设备或终端设备#A可以确定与该终端设备#A的标识相对应的符号序列#A,作为该终端设备#A所对应的符号序列。
从而,在网络设备进行反馈时,可以将同一终端设备组中反馈结果为ACK的多个终端设备所对应的符号序列叠加,并承载于如上所述确定的同一反馈时频资源中,发送给该各终端设备,各终端设备根据各自所对应的符号序列对承载于该反馈时频资源中的信息(由多个符号序列叠加而成)进行相关处理(例如,自相关处理),从而各终端设备能够判定该信息中是否携带有与其相对符号序列,如果判定结果为是,则表明网络设备对其反馈的结果为ACK;如果判定结果为否,则表明网络设备对其反馈的结果为NACK。
类似地,在网络设备进行反馈时,也可以将同一终端设备组中反馈结果为NACK的多个终端设备所对应的符号序列叠加,并承载于如上所述确定的同一反馈时频资源中,发送给该各终端设备,各终端设备根据各自所对应的符号序列对承载于该反馈时频资源中的信息(由多个符号序列叠加而成)进行自相关处理,从而各终端设备能够判定该信息中是否携带有与其相对符号序列,如果判定结果为是,则表明网络设备对其反馈的结果为NACK;如果判定结果为否,则表明网络设备对其反馈的结果为ACK。
现有技术中,采用物理混合自动请求重传指示信道(PHICH,Physical HARQ Indication Channel)承载针对上行共享信道数据包的HARQ应答信息,终端设备根据应答信息决定是否进行上行数据包的重传,因此对应答信息的可靠性有比较高的要求,由于ACK/NACK信息由1bit信令表示,信息长度很短,因此采用了重复编码、低阶调制、正交扩展、加扰、时频分集映射等方式保证ACK/NACK的传输性能。
目前LTE系统中的具体处理方式如下,在常规循环前缀(CP,Cyclic Prefix)情况下,8个ACK/NACK比特(bit)构成一个组,每个ACK/NACK bit经过三倍重复、二进制相移键控(BPSK,Binary Phase Shift Keying)调制后与长度为4的正交扩展序列相乘,而后将一组内的多路信号进行叠加并加扰,映射在控制区域的3个离散资源单元组(REG,Resource Element Group)上。扩展CP的处理流程与上述类似,只是一个PHICH组包好4个ACK/NACK比特并且正交扩展序列长度为2。此时进行码分复用的ACK/NACK比特个数减少为常规CP情况下的一半,这是因为扩展CP通常使用在频率选择性比较明显的信道环境下,此时序列之间的正交性会受到信 道的影响而由比较明显的下降。
假设采用Grant-free系统正交频分复用(OFDM,Orthogonal Frequency Division Multiplex)框架,系统带宽6RB(1.08MHz),单个CTU access region占用的时频资源的大小为一个资源块(RB,Resource Block),150%的SCMA码本,每个码本对应导频数为6,则极端情况下,用于ACK/NACK应答的资源单元(RE,Resource Element)数为3240。
每个而上述参数下,系统的总的RE数为10080。
可以发现反馈需要占据将近1/3的资源,如果考虑IOT场景下小包传输情况,CTU access region更小、单位时间内容纳用户数更多,则用于反馈的RE数需求也会进一步增加,显然,考虑到其他系统信令的开销,下行信道无法提供如此多的资源用于应答。
与此相对,根据本发明实施例的传输信息的方法,使用相同的码域资源或上行时频资源进行上行传输的多个终端设备与多个正交的符号序列一一对应,并根据各终端设备所对应的符号序列生成反馈结果的指示信息并承载于在同一反馈时频资源,能够实现在同一时频资源上进行多个终端设备的反馈,能够减小对时频资源的开销,提高通信系统在单位时间内容纳终端设备的数量,提高传输效率,并能够进一步提高传输的可靠性。
并且,如上所述,存在多个终端设备复用同一CTU access region(即,时频资源的一例)进行上行传输的情况,并且,存在多个终端设备复用同一码域资源进行上行传输的情况,因此,可能存在多个终端设备所对应的反馈时频资源相同,通过使使用相同的码域资源或上行时频资源进行上行传输的多个终端设备与多个正交的符号序列一一对应,并根据各终端设备所对应的符号序列生成反馈结果的指示信息并承载于在同一反馈时频资源,能够避免出现因复用同一CTU access region或使用同一码域资源的终端设备因选择相同的反馈时频资源而导致无法准确传输反馈结果的情况。
这里,作为确定上述终端设备组的分组依据(或者说,确定使用同一符号序列集合的多个终端设备的依据),可以是各终端设备所使用的码域资源(即,情况1),即,使用同一码域资源的终端设备需要使用属于同一符号序列集合中的彼此正交的符号序列,相对应地,可以根据码域资源来确定反馈时频资源,以确保使用不同码域资源的终端设备对应不同的反馈时频资源,进而,能够确保同一反馈时频资源上承载的符号序列属于同一符号序列集合 而彼此正交。
或者,作为确定上述终端设备组的分组依据,还可以是各终端设备所使用的时频资源,例如,上述CTU access region(即,情况2),即,使用同一时频资源的终端设备需要使用属于同一符号序列集合中的彼此正交的符号序列,相对应地,可以根据时频资源来确定反馈时频资源,以确保使用不同的时频资源的终端设备对应不同的反馈时频资源,进而,能够确保同一反馈时频资源上承载的符号序列属于同一符号序列集合而彼此正交。
下面,分别对以上两种情况下,确定反馈资源的方法进行详细说明。
情况1
首先,对本发明实施例中的“码域资源”进行说明。
可选地,该免授权码域资源包括稀疏码分多址SCMA码本、低密度签名LDS序列或码分多址CDMA码。
具体地说,在本发明实施例中,可以采用SCMA码本、LDS序列或CDMA码作为码域资源,应理解,以上列举的作为码域资源的具体实例仅为实例性说明,本发明并不限定于此,其他能够用于传输的码本均落入本发明的保护范围内。
可选地,该SCMA码本包括至少两个码字,该SCMA码本用于指示至少两种数据组合与该至少两个码字的映射关系,该码字为多维复数向量,用于指示数据与多个调制符号之间的映射关系,该调制符号包括至少一个零调制符号和至少一个非零调制符号
具体地说,稀疏码多址接入(SCMA,Sparse Code Multiple Access)是一种非正交的多址接入技术,当然本领域技术人员也可以不把这个技术称之为SCMA,也可以称为其他技术名称。该技术借助码本在相同的传输资源上传输多个不同的数据流,其中不同的数据流使用的码本不同,从而达到提升资源的利用率。数据流可以来自同一个终端设备也可以来自不同的终端设备。
SCMA采用的码本为两个或两个以上码字的集合。
其中,码字可以为多维复数域向量,其维数为两维或两维以上,用于表示数据与两个或两个以上调制符号之间的映射关系,该映射关系可以为直接映射关系,该调制符号包括至少一个零调制符号和至少一个非零调制符号,数据可以为二进制比特数据或者多元数据可选的,零调制符号和非零调制符号的关系可以为零调制符号个数不少于非零调制符号个数。
码本由两个或两个以上的码字组成。码本可以表示一定长度的数据的可能的数据组合与码本中码字的映射关系,该映射关系可以为直接映射关系。
SCMA技术通过将数据流中的数据按照一定的映射关系直接映射为码本中的码字即多维复数向量,实现数据在多个资源单元上的扩展发送。SCMA技术中的直接映射关系可以理解为数据流中的数据不需要被映射为中间调制符号,或者有其他中间处理过程。这里的数据可以是二进制比特数据也可以是多元数据,多个资源单元可以是时域、频域、空域、时频域、时空域、时频空域的资源单元。
SCMA采用的码字可以具有一定稀疏性,比如说码字中的零元素数量可以不少于调制符号数量,以便于接收端可以利用多用户检测技术来进行较低复杂度的译码。这里,以上列举的零元素数量与调制符号的关系仅为稀疏性一个示例性说明,本发明并不限定于此,零元素数量与非零元素数量的比例可以根据需要任意设定。
在使用SCMA的通信系统中,多个用户复用同一个时频资源块进行数据传输。每个资源块由若干资源RE组成,这里的RE可以是OFDM技术中的子载波-符号单元,也可以是其它空口技术中时域或频域的资源单元。例如,在一个包含L个终端设备的SCMA系统中,可用资源分成若干正交的时频资源块,每个资源块含有U个RE,其中,该U个RE可以是在时域上的位置相同。当终端设备#L发送数据时,首先将待发送数据分成S比特大小的数据块,通过查找码本(由网络设备确定并下发给该终端设备)将每个数据块映射成一组包括U个调制符号的调制符号序列X#L={X#L1,X#L2,…,X#LU},序列中的每个调制符号对应资源块中一个RE,然后根据调制符号生成信号波形。对于S比特大小的数据块,每个码本含有2S个不同的调制符号组,对应2S种可能的数据块。
上述码本也可以称为SCMA码本是SCMA码字集合,SCMA码字是一种信息比特到调制符号的映射关系。即,SCMA码本为上述映射关系的集合。
另外,在SCMA中,每个终端设备所对应的组调制符号X#k={X#k1,X#k2,…,X#kL}中,至少一个符号为零符号,并且,至少一个符号为非零符号。即,针对一个终端设备的数据,在L个RE中,只有部分RE(至少一个RE)承载有该终端设备的数据。
图5示出了以6个数据流复用4个资源单元作为举例的SCMA的比特 映射处理(或者说,编码处理)的示意图,如图5所示,6个数据流组成一个分组,4个资源单元组成一个编码单元。一个资源单元可以为一个子载波,或者为一个RE,或者为一个天线端口。在图5中,数据流和资源单元之间有连线表示至少存在该数据流的一种数据组合经码字映射后会在该资源单元上发送非零的调制符号,而数据流和资源单元之间没有连线则表示该数据流的所有可能的数据组合经码字映射后在该资源单元上发送的调制符号都为零。数据流的数据组合可以按照如下阐述进行理解,例如,二进制比特数据流中,00、01、10、11为所有可能的两比特数据组合。为了描述方便,每个数据流的数据分别表示为s1至s6,每个资源单元发送的符号分别表示为x1至x4,并且数据流和资源单元之间的连线表示该数据流的数据经扩展后会在该资源单元上发送调制符号,其中,该调制符号可以为零符号(与零元素相对应),也可以为非零符号(与非零元素相对应),数据流和资源单元之间没有连线则表示该数据流的数据经扩展后不会在该资源单元上发送调制符号。
从图5中可以看出,每个数据流的数据经扩展后会在多个资源单元上发送,同时,每个资源单元发送的符号是来自多个数据流的数据经扩展后的非零符号的叠加。例如数据流3的数据s3经扩展后会在资源单元1和资源单元2上发送非零符号,而资源单元3发送的数据x2是数据流2、数据流4和数据流6的数据s2、s4和s6分别经扩展后得到的非零符号的叠加。由于数据流的数量可以大于资源单元的数量,因而该SCMA系统可以有效地提升网络容量,包括系统的可接入用户数和频谱效率等。
码本中的码字通常具有如下形式:
Figure PCTCN2016087947-appb-000001
而且,相对应的码本通常具有如下形式:
Figure PCTCN2016087947-appb-000002
其中,N为大于1的正整数,可以表示为一个编码单元所包含的资源单元数量,也可以理解为码字的长度;Qm为大于1的正整数,表示码本中包含的码字数量,与调制阶数对应,例如,在采样四相相移键控(QPSK,Quadrature Phase Shift Keying)或4阶调制时Qm为4;q表示Qm个码字中的第q个码字,q为正整数,且1≤q≤Qm;码本和码字所包含的元素cn,q为复数,cn,q数学上可以表示为:
cn,q∈{0,α*exp(j*β)},1≤n≤N,1≤q≤Qm
α可以为任意实数,β可以为任意值,N和Qm可以为正整数。
并且,码本中的码字可以和数据形成一定映射关系,例如码本中的码字可以与2比特数据形成一种映射关系。
例如,“00”可以对应码字1,即
Figure PCTCN2016087947-appb-000003
“01”可以对应码字2,即
Figure PCTCN2016087947-appb-000004
“10”可以对应码字3,即
Figure PCTCN2016087947-appb-000005
“11”可以对应码字4,即

结合上述图3,当数据流与资源单元之间有连线时,数据流对应的码本和码本中的码字应具有如下特点:码本中至少存在一个码字在相应的资源单元上发送非零的调制符号,例如,数据流3和资源单元1之间有连线,则数据流3对应的码本至少有一个码字满足c1,q≠0,1≤q≤Qm
当数据流与资源单元之间没有连线时,数据流对应的码本和码本中的码字应具有如下特征:码本中所有码字在相应的资源单元上发送为零的调制符 号,例如,数据流3和资源单元3之间没有连线,则数据流3对应的码本中的任意码字满足c3,q=0,1≤q≤Qm
综上所述,当调制阶数为QPSK时,上述图3中数据流3对应的码本可以具有如下形式和特征:

举例地,如果数据流3的数据s3为“10”,则根据前述映射规则,该数据组合映射为码字即4维复数向量:
Figure PCTCN2016087947-appb-000010
可选地,该LDS序列包括至少两个签名序列,该LDS序列用于指示至少两种数据组合与该至少两个签名序列的映射关系,该签名序列为多维复数向量,该多维向量包括至少一个零元素和至少一个非零元素,该签名序列用于对调制符号进行幅度和相位的调整,该调制符号是通过调制星座对数据进行星座映射后得到的。
具体地说,低密度签名(LDS,Low Density Signature)技术也是一种非正交多址接入和传输技术,当然该LDS技术在通信领域还可以被称为其他名称。该类技术将来自一个或多个用户的O(O为不小于1的整数)个数据流叠加到P(P为不小于1的整数)个子载波上进行发送,其中每个数据流的每个数据都通过稀疏扩频的方式扩展到P个子载波上。当O的取值大于P时,该类技术可以有效地提升网络容量,包括系统可接入用户数和频谱效率等。因此,LDS技术作为一种重要的非正交接入技术,已经引起越来越多的关注,并成为未来无线蜂窝网络演进的重要备选接入技术。
如图5所示,以6个数据流复用4个资源单元为例进行说明,即O=6, 且P=4,其中,O为正整数,表示数据流的数量;P为正整数,表示资源单元的数量。一个资源单元可以为一个子载波,或者为一个资源粒子(Resource Element,简称为“RE”),或者为一个天线端口。其中,6个数据流组成一个分组,4个资源单元组成一个编码单元。
在图6所示的二分图中,数据流和资源单元之间有连线表示至少存在该数据流的一种数据组合,该数据组合经星座映射以及幅度和相位的调整后在该资源单元上发送非零调制符号,而数据流和资源单元之间没有连线则表示该数据流的所有可能的数据组合经星座映射以及幅度和相位的调整后在该资源单元上发送的调制符号都为零调制符号。数据流的数据组合可以按照如下阐述进行理解,例如,在二进制比特数据流中,00、01、10、11为两比特数据的所有可能数据组合。为了描述方便,用s1至s6依次表示该二分图中6个数据流待发送的数据组合,用x1至x4依次表示该二分图中4个资源单元上发送的调制符号。
从该二分图中可以看出,每个数据流的数据组合经星座映射以及幅度和相位的调整后会在两个或两个以上的资源单元上发送调制符号,同时,每个资源单元发送的调制符号是来自两个或两个以上的数据流的数据组合经各自星座映射以及幅度和相位的调整后的调制符号的叠加。例如,数据流3的待发送数据组合s3经星座映射以及幅度和相位的调整后可能会在资源单元1和资源单元2上发送非零调制符号,而资源单元3发送的调制符号x3是数据流2、数据流4和数据流6的待发送数据组合s2、s4和s6分别经各自星座映射以及幅度和相位的调整后得到的非零调制符号的叠加。由于数据流的数量可以大于资源单元的数量,因而该非正交多址接入系统可以有效地提升网络容量,包括系统的可接入用户数和频谱效率等。
进一步地,如图6所示,数据流的数据(b1,b2)经星座映射后得到的调制符号为q,使用签名序列中的每一个元素,即调整因子,对调制符号q进行相位和幅度的调整,得到每个资源单元上发送的调制符号,分别为q*s1、q*s2、q*s3和q*s4。
应理解,以上列举的作为码域资源而列举的SCMA码本和LDS序列仅为示例性说明,本发明并未限定于此,还可以列举CDMA码等,这里,CDMA码的具体作用和使用方法可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
下面,对根据码域资源确定反馈资源的方法进行详细说明。

进一步可选地,终端设备在进行上行传输时所使用的时频资源所属于的时频资源集合可以是终端设备在进行上行传输时所使用的CTU对应的时频资源所属于的时频资源的集合,CTU对应的时频资源也可以理解为CTU所属接入区域。
以上时频资源集合具体实现可以是时频资源集合的索引,以上码域资源具体实现也可以是码域资源的索引。可选地,该网络设备根据终端设备在进行上行传输时所使用的时频资源和码域资源,确定与该终端设备相对应的反馈时频资源,包括:网络设备根据终端设备在进行上行传输时所使用的码域 资源所属于的码域资源集合和时频资源,确定与该终端设备相对应的反馈时频资源,其中,该码域资源集合包括至少一个码域资源。
进一步可选地,进行上行传输时所使用的码域资源所属于的码域资源集合可以是终端设备进行上行传输时数据部分所使用的码域资源所属于的码域资源集合。
进一步可选地,终端设备在进行上行传输时所使用的时频资源可以是终端设备在进行上行传输时所使用的CTU对应的时频资源,CTU对应的时频资源也可以理解为CTU所属的接入区域。

具体地说,在本发明实施例中,一个码域资源集合可以包括一个或多个码域资源(例如,码本)。
此情况下,一个符号序列集合对应一个码域资源集合,具体地说,一个符号序列集合中的各元素与一个码域资源集合中的各元素一一对应,这里,一个符号序列集合中的各元素为该符号序列集合中的多个彼此正交的符号序列,一个码域资源集合中的各元素为一个码域资源集合中的多个码域资源,即,以码域资源集合为单位配置符号序列集合,或者说,当多个码域资源与多个导频一一对应时,同一符号序列集合中的多个(部分或全部)正交的符号序列还可以与该符号序列集合所对应的码域资源集合中的多个码域资源所对应的导频一一对应。
例如,当码域资源集合中仅包括一个码域资源时,该一个码域资源中的各导频与符号序列集合中的多个符号序列一一对应。
再例如,当码域资源集合中包括多个码域资源时,该多个码域资源中的各导频与符号序列集合中的多个符号序列一一对应。
下面,对符号序列(或者说,符号序列集合)的生成方法进行详细说明。
例如,符号序列集合可以由WASH序列按照Hadamard矩阵扩展生成,假设每个码域资源对应的终端设备为6个(或者说,每个码域资源对应的导频为6个,该6个导频与6各终端设备一一对应),因此扩展出4阶的WASH正交序列组即可(共8个正交序列,最多可支持8个终端设备)。具体生成过程可以由以下公式示出:
Figure PCTCN2016087947-appb-000011
其中H2为2阶Hadamard矩阵,经过递推矩阵H2N扩展后,生成4阶的Hardamard矩阵,取矩阵的列向量即可获得4个4阶WASH正交序列;将列向量元素1用虚数
Figure PCTCN2016087947-appb-000012
替换后,获得另外4个4阶WASH序列,由此一共获得8个相互正交的4阶WASH序列。更高阶的WASH序列生成可以此类推。以下表1示出了如上所述生成的符号序列(4阶WASH序列)的一例。

4 j,j,j,j
5 j,-j,j,-j
6 j,j,-j,-j
7 j,-j,-j,j
例如,在码域资源集合中只包括一个码域资源时,由于每个码域资源所对应终端设备(或者说,导频)数为6个,因此只需从生成的WASH序列集合中选取6个就可以满足与导频一一对应的要求,例如,可以取前6个正交序列,按照序号与导频一一映射。以下表2示出了各终端设备与各符号序列的对应关系的一例。

1 1,-1,1,-1
2 1,1,-1,-1

再例如,在码域资源集合中包括K码域资源,并且每个码域资源所对应终端设备(或者说,导频)数为6个时,需从生成的WASH序列集合中选取6K个符号序列就可以满足与导频一一对应的要求,按照序号与导频一一映射。
应理解,以上列举的WASH序列的生成方式进行示例性说明,本发明并不限定于此,还可以采用不同阶数的Hadamard矩阵可以生成所包含的符号序列数量相异的符号序列集合,从而能够支持不同数量的终端设备复用同一反馈时频资源。

或者,符号序列集合可以由多个Golden序列构成,例如,该Golden序列可以由两个5阶、构成优选对的m序列模2加生成,具体地说,由于每改变两个m序列相对位移即可得到一个新的Golden序列,加上原来两个m序列本身,所以5级m序列可以产生2m-1共33个Golden序列,最多支持33个导频。更高阶的Golden序列可以基于高阶m序列递推产生。

应理解,以上列举的Golden序列的生成方法以及具体实例仅为示例性说明,本发明并不限定于此,例如,还可以根据以下表5所示m序列反馈系数生成相应的Golden序列。

例如,在码域资源集合包括K码域资源时,如果每个码域资源所对应导频数为6个,则需从生成的WASH序列组中选取6K个符号序列,以满足所选择的符号序列与多个导频一一对应的要求。
当一个码域资源与一个符号序列集合相对时,可能出现使用该码域资源的终端设备的数量(或者说,该码域资源所对应的导频的数量)小于一个符号序列集合中的符号序列的数量,进而导致该符号序列集合中的符号序列未被任何终端设备选择而被浪费的情况。
鉴于上述情况,根据本发明实施例的传输信息的方法,可以由多个码域资源构成一个码域资源集合,并使该码域资源集合与一个符号序列集合相对应,(例如,使一个码域资源集合包括各码域资源所对应的导频与一个符号序列集合中的各符号序列一一对应),能够使符号序列集合中的符号序列均被利用,从而能够进一步节约传输资源。
并且,网络设备可以确定各终端设备所对应的反馈时频资源。
例如,在本发明实施例中,使用不同码域资源集合的终端设备对应不同的符号序列结合,并且,使用不同码域资源集合的终端设备对应的反馈时频资源也相异,从而,使用不同码域资源的终端设备所对应的反馈时频资源相异,并且,使用同一码域资源集合的终端设备的符号序列彼此正交,能够承载于同一反馈时频资源。
除此之外,为了确保传输的可靠性,还可以采用以下方式确定时频资源。
具体地说,可能存在,例如,在使用上行CTU access region集合#A(包括至少一个CTU access region)的多个终端设备与使用上行CTU access region集合#B(包括至少一个CTU access region)的多个终端设备选择同一符号序列集合的情况,由于符号序列集合能够提供的正交序列有限,则可能出现多个用户选择同一符号序列的情况,
例如,如果使用上行CTU access region集合#A的终端设备为6个,使用上行CTU access region集合#B的终端设备为6个,如上所述生成的WASH序列集合包括的正交的符号序列为8个,则能够提供的正交的符号序列的数量8小于选择同一反馈时频资源的终端设备的数量12。
因此,通过使使用上行CTU access region集合#A的终端设备与使用上行CTU access region集合#B的终端设备对应不同的反馈时频资源,即,通过使对应不同上行CTU access region集合(即,上行时频资源的一例)但对 应相同码域资源集合(即,码域资源的一例)的终端设备对应不同的反馈时频资源,能够使使用同一反馈时频资源的终端设备的数量小于或等于一个符号序列集合中的符号序列数量,能够确保传输的可靠性。
例如,作为实例而非限定,可以根据以下公式确定各终端设备所对应的反馈时频资源:
Figure PCTCN2016087947-appb-000013
其中,REindex表示终端设备所对应的反馈时频资源,CTUindex表示终端设备在进行上行传输(例如,免授权传输)时使用的时频资源(例如,该终端设备所使用的CTU所对应的CTU access region)的索引,Codebookindex表示终端设备使用的码域资源(例如,码本)的索引,a表示系统所提供的码域资源(或者说,该终端设备所使用的CTU所对应的码域资源)的数量,b可以根据一个符号序列集合中彼此正交的符号序列的数量(或者说,一个码域资源所对应的导频的数量)确定,例如,在使用WASH序列作为上述符号序列时,b表示Hadamard矩阵的阶数,并且,该Hadamard矩阵的阶数根据所需要生成的正交的符号序列的数量(或者说,一个时频资源集合所对应的导频的数量)决定,c表示终端设备所使用的码域资源所属于的码域资源集合所包括的码域资源的数量。
需要说明的是,当终端设备在进行上行传输时使用的时频资源所属于的时频资源集合仅包括一个时频资源时,上述参数b也可以直接根据该时频资源所对应的导频(或者说,使用时频资源的终端设备)的数量确定,即,调整该Hadamard矩阵的阶数,以使所生成的正交的符号序列的数量大于该时频资源所对应的导频的数量。
并且,当当终端设备在进行上行传输时使用的码域资源所属于的码域资源集合仅包括一个码域资源时,c的取值为1,因此,在使使用不同的码域资源的终端设备所对应的符号序列集合相异的情况下,还可以根据以下公式确定各终端设备所对应的反馈时频资源:
REindex∈[(CTUindex*a+Codebookindex)]*b~[(CTUindex*a+Codebookindex)+1]*b
类似地,终端设备也可以采用相似的方法和过程确定其所对应的反馈时频资源,这里,为了避免赘述,省略其详细说明。
例如,网络设备可以将对应同一反馈时频资源的多个终端设备中反馈结果为ACK的终端设备所对应的符号序列承载于该反馈时频资源,并发送。
设每个码域资源集合包括一个码域资源,设在上行传输时使用码域资源#0的终端设备为终端设备#A(例如,对应的导频#0的终端设备)、终端设备#B(例如,对应的导频#1的终端设备)、终端设备#C(例如,对应的导频#4的终端设备)。
当只有终端设备#A(或者说,导频#0)和终端设备#C(或者说,导频#4)对应的上行数据译码成功,则网络设备可以在确定该终端设备#A、终端设备#B和终端设备#C所对应的反馈时频资源(记做:反馈时频资源#A)后,将终端设备#A(或者说,导频#0)所对应的符号序列(记做:符号序列#A)和终端设备#C(或者说,导频#4)对应的符号序列(记做:符号序列#C)承载于该反馈时频资源#A。
该终端设备#A、终端设备#B和终端设备#C可以确定上述反馈时频资源#A,并接受承载于该反馈时频资源#A上的信息(即,由符号序列#A和符号序列#C叠加而成),并根据其所对应的符号序列对该信息进行自相关处理,经该自相关处理后,终端设备#A和终端设备#C能够确定上述信息中携带有其对应的符号序列,从而,能够确定网络设备的反馈结果为ACK;终端设备#B能够确定上述信息中未携带有其对应的符号序列,从而,能够确定网络设备的反馈结果为NACK。
或者,网络设备可以将对应同一反馈时频资源的多个终端设备中反馈结果为NACK的终端设备所对应的符号序列承载于该反馈时频资源,并发送。
设在上行传输时使用码域资源#0的终端设备为终端设备#A(例如,对应的导频#0的终端设备)、终端设备#B(例如,对应的导频#1的终端设备)、终端设备#C(例如,对应的导频#4的终端设备)。
当只有终端设备#A(或者说,导频#0)和终端设备#C(或者说,导频#4)对应的上行数据译码成功,则网络设备可以在确定该终端设备#A、终端设备#B和终端设备#C所对应的反馈时频资源(记做:反馈时频资源#A)后,将终端设备#B(或者说,导频#1)对应的符号序列(记做:符号序列#B) 承载于该反馈时频资源#A。
该终端设备#A、终端设备#B和终端设备#C可以确定上述反馈时频资源#A,并接受承载于该反馈时频资源#A上的信息(即,由符号序列#C构成),并根据其所对应的符号序列对该信息进行自相关处理,经该自相关处理后,终端设备#A和终端设备#C能够确定上述信息中未携带有其对应的符号序列,从而,能够确定网络设备的反馈结果为ACK;终端设备#B能够确定上述信息中携带有其对应的符号序列,从而,能够确定网络设备的反馈结果为NACK。
情况2
在本发明实施例中,一个CTU access region集合可以包括一个或多个CTU access region。
此情况下,一个符号序列集合对应一个CTU access region集合,具体地说,一个符号序列集合中的各元素与一个CTU access region集合中的各元素一一对应,这里,一个符号序列集合中的各元素为该符号序列集合中的多个彼此正交的符号序列,一个CTU access region集合中的各元素为一个CTU access region集合中的多个CTU access region,即,以CTU access region集合为单位配置符号序列集合,或者说,当多个CTU access region与多个导频一一对应时,同一符号序列集合中的多个(部分或全部)正交的符号序列还可以与该符号序列集合所对应的CTU access region集合中的多个CTU access region所对应的导频一一对应
例如,当一个CTU access region集合中仅包括一个CTU access region时,该一个CTU access region所对应的多个导频与一个符号序列集合中的多个符号序列一一对应。
再例如,当一个CTU access region集合中包括多个CTU access region时,该多个CTU access region中的各CTU access region所对应的导频与一个符号序列集合中的多个符号序列一一对应。
情况2中符号序列(或者说,符号序列集合)的生成方法与情况1类似,这里为了避免赘述省略其详细说明。
需要说明的是,在CTU access region集合中只包括一个CTU access region时,例如,如果每个CTU access region所对应码域资源为6,如果每个码域资源所对应终端设备(或者说,导频)数为6个,因此只需从生成的 WASH序列集合中选取6×6个符号序列就可以满足与导频一一对应的要求,例如,可以取前6个正交序列,按照序号与导频一一映射。
在CTU access region集合中包括多个CTU access region(例如,3个)时,例如,如果每个CTU access region所对应码域资源为6,如果每个码域资源所对应终端设备(或者说,导频)数为6个,因此只需从生成的WASH序列集合中选取3×6×6个符号序列就可以满足与导频一一对应的要求。
当一个CTU access region与一个符号序列集合相对时,可能出现使用该CTU access region的终端设备的数量(或者说,该CTU access region所对应的导频的数量)小于一个符号序列集合中的符号序列的数量,进而导致该符号序列集合中的符号序列未被任何终端设备选择而被浪费的情况。但如上段所述,3个CTU access region组成CTU access region集合时,需要的符号序列为3×6×6,如果一个符号序列集合包括36个符号序列,那么可以使得一个符号序列集合中的符号序列尽可能地被使用。
鉴于上述情况,根据本发明实施例的传输信息的方法,可以由多个CTU access region构成一个CTU access region集合,并使该CTU access region集合与一个符号序列集合相对应,(例如,使一个CTU access region集合包括各CTU access region所对应的导频与一个符号序列集合中的各符号序列一一对应),能够使符号序列集合中的符号序列均被利用,从而能够进一步节约传输资源。
并且,网络设备可以确定各终端设备所对应的反馈时频资源。
例如,在本发明实施例中,使用不同CTU access region集合的终端设备对应不同的符号序列结合,并且,使用不同码域资源的终端设备对应的反馈时频资源也相异,从而,使用不同码域资源的终端设备所对应的反馈时频资源相异,并且,使用同一码域资源的终端设备的符号序列彼此正交,能够承载于同一反馈时频资源。
作为实例而非限定,例如,以CTU access region为单位的处理时,可以根据以下公式确定各终端设备所对应的反馈时频资源:
REindex∈CTUindex*b~[CTUindex+1]*b
其中,REindex表示终端设备所对应的反馈时频资源,TRBindex表示终端设备在进行上行传输(例如,免授权传输)时使用的时频资源(例如,CTU access region)的索引,b可以根据一个符号序列集合中彼此正交的符号序列的数 量(或者说,一个码域资源所对应的导频的数量)确定,例如,在使用WASH序列作为上述符号序列时,b表示Hadamard矩阵的阶数,并且,该Hadamard矩阵的阶数根据所需要生成的正交的符号序列的数量(或者说,一个时频资源集合所对应的导频的数量)决定。
需要说明的是,当终端设备在进行上行传输时使用的时频资源所属于的时频资源集合仅包括一个时频资源时,上述参数b也可以直接根据该时频资源所对应的导频(或者说,使用时频资源的终端设备)的数量确定,即,调整该Hadamard矩阵的阶数,以使所生成的正交的符号序列的数量大于该时频资源所对应的导频的数量。
类似地,终端设备也可以采用相似的方法和过程确定其所对应的反馈时频资源,这里,为了避免赘述,省略其详细说明。
例如,网络设备可以将对应同一反馈时频资源的多个终端设备中反馈结果为ACK的终端设备所对应的符号序列承载于该反馈时频资源,并发送。
或者,网络设备可以将对应同一反馈时频资源的多个终端设备中反馈结果为NACK的终端设备所对应的符号序列承载于该反馈时频资源,并发送。
在情况2中网络设备发送反馈结果的指示信息以及终端设备确定反馈结果的过程与情况1中描述的过程类似,这里,为了避免赘述,省略其详细说明。
在本发明实施例中,当有多个终端设备选择相同免授权传输资源(例如,导频)时,其对应的符号序列也相同,此时ACK/NACK反馈可能出现误检,例如,当只有其中一个终端设备的上行数据译码成功时,所有终端设备均会在所确定的反馈时频资源上检测到对应的符号序列,判定译码成功(或者说,上行传输成功)。为避免这种情况,在本发明实施例中,可以在所确定的反馈时频资源中承载指示上述译码成功(或者失败)的终端设备的终端标识。
即,可选地,该免授权传输的反馈结果的指示信息包括承载该终端设备的相关标识的反馈时频资源的位置信息。
具体地说,在本发明实施例中,在反馈时频资源上携带反馈结果的指示信息(即,一个或多个符号序列)和该反馈结果所对应的终端设备的设备标识的指示信息。
图7示出了承载本发明实施例的反馈结果的指示信息及该反馈结果所对 应的终端设备的设备标识的指示信息的反馈信息结构示意图。
如图7所示,该反馈信息包括用于承载上述符号序列的部分,以及用承载该反馈结果所对应的终端设备的设备标识的指示信息的部分。
在本发明实施例中,该该反馈结果所对应的终端设备的设备标识的指示信息可以用于指示该该反馈结果所对应的终端设备的设备标识在数据包(例如,通过下行共享信道传输的下行数据包)中的位置。从而,仅需少量比特位便能够使终端设备获知该反馈结果所对应的终端设备的设备标识,能够进一步节约反馈信息所占用的资源。
此情况下,例如,在以终端设备所使用的码域资源所属于的码域资源集为单位分配符号序列集合的情况下,即,可以通过以下公式确定反馈时频资源:
Figure PCTCN2016087947-appb-000014
其中,n为承载反馈结果所对应的终端设备的设备标识的指示信息的资源的大小。
可选地,该反馈时频资源为物理混合自动重传请求指示信道PHICH所对应的时频资源。
