Description

上行数据传输的方法和装置
本申请要求于2015年06月25日提交中国专利局、申请号为PCT/CN2015/082357、发明名称为“上行数据传输的方法和装置”的PCT专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，并且更具体地，涉及上行数据传输的方法和装置。
背景技术
在典型无线通信网络(比如，长期演进(Long Term Evolution，简称为“LTE”网络)中，上行数据共享信道(Shared Data Channels)的选择基于调度/准许(Scheduling/Grant)机制，完全受基站(Base Station，简称为“BS”)控制。在该机制中，用户设备(User Equipment，简称为“UE”)首先向BS发出上行调度请求。当BS接收到该请求后，向UE发出上行Grant以通知该UE为该UE分配给的上行传输资源。UE据此在经过准许的上行传输资源上进行数据传输。
大规模用户接入是下一代通信网络的典型应用场景之一。当海量用户接入时，如果沿用上述Scheduling/Grant机制，则一方面将导致巨大的信令传输开销以及BS资源分配的调度压力，另一方面将造成显著的传输时延。鉴于此，下一代通信网络为支撑海量用户接入将采用免授权(Grant Free)传输方式。在Grant Free传输方式下，BS在上行传输资源中划定竞争传输单元(Contention Transmission Unit，简称为“CTU”)的接入区域。UE在该区域内以竞争方式接入上行传输资源，而无需遵循Scheduling/Grant机制。
为成功进行Grant Free上行传输，UE应当首先确定上行传输的CTU资源。确定CTU资源可以基于UE和BS双方已知的预定UE-CTU映射规则。该映射规则可以通过标准规定或固件实现等隐性方式为UE预知。也可以由BS通过显性高层信令方式予以通知。比如，不同的映射规则可以首先在标准中进行定义，然后由BS将相应映射规则的序号通过信令告知UE。
不同UE被允许采用相同特征波(特征波可以称为Signature)进行上行接入传输，Signature可以被认为是码资源。当多个UE采用相同Signature同 时接入相同的时频资源(即相同的时-频-码资源)时就会发生冲突，需要相应的高级检测方法予以解决。当多个采用相同时-频-码资源的UE进一步采用相同导频时，其冲突一般被认为是无法单纯通过检测方法解决的。此种情况需要配合特殊的冲突避免或解决机制，比如重映射、重传等。为降低特定UE或特定CTU上的冲突，部分UE可以重新映射到新的CTU资源上。
上述海量用户接入的Grant Free传输，由于允许多个UE在同一CTU资源上竞争传输，因此会导致竞争冲突，降低Grant Free传输可靠性。为确保低时延高可靠性Grant Free传输，有必要为部分有特殊业务需求的UE提供额外的传输保障。

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付出创造性劳动的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(Global System for Mobile Communication，简称为“GSM”)，宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)，长期演进(Long Term Evolution，简称为“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，还将支持机器对机器(Machine to Machine，简称为“M2M”)通信，或者叫做机器类通信(Machine Type Communication，简称为“MTC”)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，比如设备对设备(Vehicle to Vehicle，简称为“V2V”)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(User Equipment，简称为“UE”)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。终端设备可以是无线局域网(Wireless Local Area Networks，简称为“WLAN”)中的站点(Station，简称为“ST”)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“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。
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中的接入点(Access Point，简称为“AP”)，码分多址(Code Division Multiple Access，简称为“GSM”或“CDMA”)中的基站(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA中的基站(NodeB，简称为“NB”)，还可以是长期演进(Long Term Evolution，简称为“LTE”)中的演进型基站(Evolutional Node B，简称为“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。
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，压缩盘(Compact Disk，简称为“CD”)、数字通用盘(Digital Versatile Disk，简称为“DVD”)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(Erasable Programmable Read-Only Memory，简称为“EPROM”)、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示出了应用本发明实施例的一种通信系统的示意性架构图。如图1所示，该通信系统100可以包括网络设备102和终端设备104～114(图中简称为UE)通过无线连接或有线连接或其它方式连接。
该通信系统100可以是指公共陆地移动网络(Public Land Mobile Network，简称为“PLMN”)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，通信系统中还可以包括其他网络设备，图1中未予以画出。
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，或者其他类似的含义：
1、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。
2、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，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。
3、免授权传输可以指：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。
4、免授权传输可以指：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UE接收所述的信令的时刻以后的一个或多个传输时间单位的传输资源。一个传输时间单位可以是指一次传输的最小时间单元，比如传输时间间隔(Transmission Time Interval，简称为“TTI”)，数值可以为1ms，或者可以是预先设定的传输时间单元。
5、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。
6、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：
-时域资源，如无线帧、子帧、符号等；
-频域资源，如子载波、资源块等；
-空域资源，如发送天线、波束等；
-码域资源，如稀疏码多址接入(Sparse Code Multiple Access，简称为“SCMA”)码本、低密度签名(Low Density Signature，简称为“LDS”)、CDMA码等；
-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：
-上行功率控制，如上行发送功率上限控制等
-调制编码方式设置，如传输块大小、码率、调制阶数设置等；
-重传机制，如HARQ机制等。
上述传输资源可以进一步被分成一个或多个竞争传输单元(Contention Transmission Unit，简称为“CTU”)。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、导频相结合的传输资源，或者，可以指时间、频率、码域、导频相结合的传输资源。CTU的接入区域可以指用于免授权传输的时频区域。
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。
图2示出了根据本发明实施例的上行数据传输的方法的示意性流程图。该方法是由网络设备执行的，如图2所示，该方法200包括：
S210，接收包括传输模式信息的第一消息，该传输模式信息用于指示终端设备能够通过同一时间间隔TTI内的至少两个竞争传输单元CTU传输上行数据，该CTU指时间、频率、码域相结合的传输资源，或者，指时间、频率、导频相结合的传输资源，或者，指时间、频率、码域、导频相结合的 传输资源，该至少两个CTU传输的上行数据部分相同或全部相同。
也可以理解第一消息指示终端设备能够进行冗余传输，其中冗余传输包括一种传输模式：通过同一时间间隔TTI内的至少两个竞争传输单元CTU传输上行数据；对第一消息理解可以适用于其他实施例，其他实施例不在赘述。
S220，发送包括指示信息的第二消息，该指示信息用于使该终端设备根据该指示信息确定进行上行数据传输所使用的CTU。
可选地，该上行数据传输所使用的CTU包括同一TTI内的至少两个CTU，进一步可选地，该上行数据传输所使用的CTU中包括的同一TTI内的至少两个CTU用于进行冗余传输，或者称所使用的CTU中包括的同一TTI内的至少两个CTU用于传输部分相同或全部相同的上行数据。上述对于指示信息的理解可以适用于其他实施例，其他实施例不在赘述。
具体而言，网络设备接收终端设备发送的包括传输模式信息的第一消息，并根据该传输模式信息确定该终端设备能够通过同一时间间隔TTI内的至少两个竞争传输单元CTU传输上行数据，并且该终端设备通过该至少两个CTU传输的上行数据部分相同或全部相同，网络设备接收到该第一消息后，可以确定终端设备用于确定进行上行数据传输能够使用的CTU的指示信息，并向终端设备发送包括该指示信息的第二消息。
因此，本发明实施例的上行数据传输的方法，网络设备接收终端设备发送的包括传输模式信息的第一消息，并向该终端设备发送包括指示信息的第二消息，使得该终端设备可以根据该指示信息确定进行上行数据传输所使用的CTU，由于终端设备能够通过同一TTI内的至少两个CTU传输上行数据，因此能够提升数据传输的可靠性，并能降低传输时延。
应理解，在本发明实施例中，冗余传输可以理解包含如下一种传输方式：在一次数据传输过程中所传输的数据至少包括第一数据和第二数据，且该第二数据与该第一数据部分相同或全部相同。当然冗余传输也可以被称为可靠性传输，或者属于可靠性传输的一种类别。冗余传输或者可以被称为包含上述传输方式的其他名称。
可选地，本发明实施例的方法能够应用于如下领域中的任意一个或多个领域：设备到设备D2D领域、机器对机器M2M领域、机器类通信MTC领域。但本发明并不限于此。
可选地，本发明实施例中的上行数据的传输为免授权传输。
在本发明实施例中，可选地，不能进行冗余传输的终端设备可以向网络设备发送传输模式信息，指示该终端设备不能进行冗余传输，而能够进行冗余传输的终端设备不向网络设备发送传输模式信息，网络设备在一定时间内未接收到终端设备发送的传输模式信息，可以认为该终端能够进行冗余传输。或者能够进行冗余传输的终端设备向网络设备发送传输模式信息，指示该终端设备能够进行冗余传输，不能进行冗余传输的终端设备不向网络设备发送传输模式信息，网络设备在一定时间内未收到终端设备发送的传输模式信息，则认为该终端设备不能进行冗余传输，但本发明并不限于此。
应理解，在终端设备不能进行冗余传输时，网络设备同样也会向该终端设备发送包括指示信息的消息，此时，该终端设备可以根据该指示信息确定进行常规传输所采用的CTU，并进行初始传输或重传。
可选地，在S210中，该至少两个CTU传输的上行数据部分相同或全部相同可以理解为：该至少两个CTU中的每个CTU传输待传输的上行数据的一部分数据且每个CTU传输的数据不同；或者，该至少两个CTU中的某些CTU传输相同且完整的待传输的上行数据，该至少两个CTU中其他的CTU传输该待传输的上行数据的部分数据。本发明对此不作限定。
可选地，在S210中，网络设备可以通过某一上行公共控制信道接收终端设备发送的该第一消息，该第一消息还可以包括该终端设备进行冗余传输的相应要求，本发明对此不作限定。
举例来说，终端设备可以在RRC连接建立请求消息(RRC ConnectionRequest Message)中添加与冗余传输相关的字段。例如，可以在RRC连接建立请求消息中增加包括但不限于以下指示信息中的任一种指示信息：grantFreeCapability BITSTRING(SIZE(8))，指示不同的免授权(Grant Free)支撑能力，该指示信息包括的8个比特中的一个比特用于指示终端设备是否能够进行冗余传输，例如，可以在该一个比特的值取1时，指示该终端设备能够进行冗余传输(1-Enable)，在该一个比特的值取0时，指示该终端设备不能够进行冗余传输(0-Disable)；candidateMappingRule，指示备选CTU序号映射规则集合，redundantTransmissionPattern，指示数据传输模式，这个redundantTransmissionPattern可以为上述传输模式信息的一种举例。当指示终端设备是否能够进行冗余传输和指示数据传输模式的信息比如上述 的比特信息同时存在的时候，那么可以理解为冗余传输可以包括多种数据传输模式，能够通过同一时间间隔TTI内的至少两个竞争传输单元CTU传输上行数据是其中一种传输模式。
在本发明实施例中，可选地，可以在现有标准的传输模式(Transmission mode)定义中添加Grant Free时频分集传输模式来确定冗余传输时的传输模式，例如，可以按表1所示的方法定义：
表1
Figure PCTCN2016087333-appb-000001

可选地，在S220中，网络设备可以使用广播信道，如长期演进LTE系统中的广播控制信道(Broadcast Control Channel，简称为“BCCH”)，以广播的方式向系统中的全部或部分终端设备发送包括指示信息的消息；也可以使用专用控制信道，如长期演进LTE系统中的(Dedicated Control Channel，简称为“DCCH”)，以单播的方式向特定的一个或一组终端设备发送包括指示信息的消息等；也可以使用其他信道，以其他方式向系统中的全部终端设备，或部分终端设备，或特定的一个终端设备或一组终端设备下发包括指示信息的消息，本发明对此不作限定。

举例来说，网络设备可以在无线资源控制消息(RRC Message)中添加与冗余传输相关的指示信息。例如，可以在现有标准的“SystemInformationBlockTypeX”中添加“grantFreeCapability BITSTRING(SIZE(8))”来定义不同的Grant Free支撑能力，该8个比特中的一个比特用于指示网络设备是否能够支持冗余传输，例如，可以在该一个比特的值取1时，指示该网络设备能够支持冗余传输(1-Enable)，在该一个比特的值取0时，指示该网络设备不能支持冗余传输(0-Disable)。网络设备可以在RRC 连接建立消息中增加包括但不限于以下指示信息中的任一种或多种指示信息：ueDCSIndex，指示UE专属的DCS序号；ctuAccessRegion，指示CTU接入区域；ctuNumber，指示CTU接入区域中的CTU的数量；ctuMappingRule，指示UE-CTU序号映射规则。
在本发明实施例中，可选地，该CTU序号映射规则信息是根据如下参数中的任意一个或多个确定CTU序号的规则：该终端设备的DCS的信息；该终端设备能够用于传输上行数据的CTU的数量；该CTU接入区域中的CTU的数量；该CTU接入区域中的起始CTU的序号。
在本发明实施例中，可选地，该确定CTU序号的规则为如下公式中的任意一种或多种：
ITR-ij＝(ITR-INT+DCSi+j)mod NTR，或
ITR-ij＝f(ITR-INT+DCSi+j)mod NTR，
其中，j＝0，1，...，Δi-1，DCS1＝0，DCSi＝DCSi-1+Δi-1，i＝2，3......，f(·)为交织函数，交织范围为[0...NTR-1]，ITR-ij为CTU的序号，ITR-INT为该CTU接入区域中的起始CTU的序号，DCSi为终端设备UEi的DCS，Δi为该UEi能够用于传输上行数据的CTU的数量，NTR为该CTU接入区域中的CTU的数量。
在本发明实施例中，可选地，能够进行冗余传输的终端设备和不能进行冗余传输的终端设备可以具有相同的CTU接入区域，由此可以提高传输资源的利用率。
在本发明实施例中，可选地，可以划定冗余传输的专属区域，该专属区域可以理解只允许能够进行冗余传输的终端设备竞争接入，进行上行数据的传输，而冗余传输可以按照上述进行理解。也就是说该CTU接入区域也可以被称为用于冗余传输的CTU接入区域，或者说，该CTU接入区域为用于可靠性传输的CTU接入区域，或者说，该CTU接入区域为可靠-低时延(Reliable Ultra-Low Latency，简称为“RULL”)传输的CTU接入区域，或者其他名称的接入区域，但本发明并不限于此。
相应地，该CTU序号映射规则信息是根据如下参数中的任意一个或多个确定CTU序号的规则：该终端设备的DCS的信息；该终端设备能够用于冗余传输上行数据的CTU的数量；该用于冗余传输的CTU接入区域中的CTU的数量；该用于冗余传输的CTU接入区域中的起始CTU的序号。
可选地，该确定CTU序号的规则为如下公式中的任意一种或多种：
ITR-ij＝(ITR-INT+DCSi+j)mod NTR，或
ITR-ij＝f(ITR-INT+DCSi+j)mod NTR，
其中，j＝0，1，...，Δi-1，DCS1＝0，DCSi＝DCSi-1+Δi-1，i＝2，3......，f(·)为交织函数，交织范围为[0...NTR-1]，ITR-ij为CTU的序号，ITR-INT为该用于冗余传输的CTU接入区域中的起始CTU的序号，DCSi为终端设备UEi的DCS，Δi为该UEi能够用于冗余传输上行数据的CTU的数量，NTR为该用于冗余传输的CTU接入区域中的CTU的数量。
在本发明实施例中，可选地，该CTU接入区域为一个或多个CTU接入区域，其中，该多个CTU接入区域为属于同一个TTI的CTU接入区域。也就是说，终端设备可以在同一个TTI内映射至多个CTU进行上行数据的传输。
举例来说，图3(a)～(d)示出了根据本发明实施例的终端设备与同一个TTI内的CTU的映射关系图。在图3(a)中，序号依次为UE1～UE8的8个终端设备共映射至8个CTU，每个CTU上均有两个不同终端进行上行数据的传输。8个终端设备按照第一种CTU序号映射规则定义的组合方式映射至第一组4个CTU302-308。其中，UE1和UE2映射至CTU302，UE3和UE4映射至CTU304，UE5和UE6映射至CTU306，UE7和UE8映射至CTU308。同时这8个终端设备又按照第二种CTU序号映射规则定义的组合方式映射至第二组4个CTU310-316。其中，UE1和UE5映射至CTU310，UE2和UE6映射至CTU312，UE3和UE7映射至CTU314，UE4和UE8映射至CTU316。
如果时频资源充足且终端设备有进一步增加冗余传输自由度的需求，则上述全部或部分终端设备可继续按照类似CTU序号映射规则所定义的组合方式映射至同一TTI内其它CTU上。比如，在图3(b)中，这8个终端设备又按照第三CTU序号映射规则定义的组合方式映射至第三组4个CTU318-324。其中，UE1和UE3映射至CTU318，UE5和UE7映射至CTU320，UE2和UE4映射至CTU322，UE6和UE8映射至CTU324。以此类推，上述终端设备可以按照其它CTU序号映射规则定义的组合方式映射至其它组CTU。
在考虑多组终端设备冗余传输时，多组终端设备可以全部或部分地映射 至上述全部或部分CTU资源。例如，在图3(c)中，第二组终端设备的一部分UE11和UE13分别映射至CTU302和CTU304，第三组终端设备的一部分UE16和UE17分别映射至CTU312和CTU314。
在本发明实施例中，进行冗余传输的终端设备和进行常规传输的终端设备可以映射至同一TTI内的CTU，例如，如图3(d)所示，在同一TTI内，UE1，UE2和UE5进行Grant Free冗余传输，其中UE1映射至CTU302和CTU310，UE2映射至CTU302和CTU312，UE5映射至CTU306和310。UE3，UE4，UE7和UE8进行GrantFree常规传输，其中UE3映射至CTU304，UE4映射至CTU316，UE7映射至CTU314，UE8映射至CTU308。以此类推，上述终端设备还可以按照其他CTU序号映射规则定义的组合方式映射至不同的CTU上，本发明对此不作限定。
在本发明实施例中，可选地，该多个CTU接入区域还进一步包括属于不同TTI的CTU接入区域。也就是说，终端设备可以映射至不同TTI内的CTU上进行上行数据的传输。
举例来说，图4示出了根据本发明实施例的终端设备与多个TTI内的CTU的映射关系。如图4所示，UE6，UE7和UE8在TTI1内进行GrantFree常规传输，其中UE6映射至CTU404，UE7映射至CTU414，UE8映射至CTU408。UE12在TTI2内进行Grant Free常规传输，映射至CTU416。UE13和UE15在TTI3内进行Grant Free常规传输，其中UE13映射至CTU408，UE15映射至CTU416。
其它UE分别在多个TTI内进行Grant Free冗余传输。其中，UE1映射至TTI1内的CTU402，TTI2内的CTU402和CTU410。UE2映射至TTI1内的CTU402和CTU410。UE3映射至TTI1内的CTU410，TTI2内的CTU410和CTU414。UE4映射至TTI1内的CTU416，TTI2内的CTU404和TTI3内的CTU412。UE5映射至TTI1内的CTU406和CTU410，TTI2内的CTU404。UE9映射至TTI2内的CTU406，TTI3内的CTU406和CTU410。UE10映射至TTI2内的CTU408和TTI3内的CTU408。UE11映射至TTI2内的CTU612和TTI3内的CTU406。UE14映射至TTI3内的CTU404和CTU414。但本发明并不限于此。
在本发明实施例中，可选地，通过该至少两个CTU来传输的上行数据为重传数据。也就是说，终端设备可以根据该指示信息确定进行初始传输的 CTU和进行重传的CTU，终端设备在确定初始传输失败时，根据该指示信息确定用于进行重传的CTU进行重传数据的传输。
在本发明实施例中，可选地，在网络设备未成功接收上行数据的部分数据时，终端设备可以选择重传未被成功接收的该部分数据，也可以选择重传全部数据，在该网络设备未成功接收该上行数据的全部数据时，该终端设备重新传输该上行数据的全部，本发明对进行重传时采用的数据传输模式不作限定。
在本发明实施例中，可选地，在终端设备传输上行数据失败时，还可以根据新的CTU序号映射规则确定用于进行重传的CTU，该新的CTU序号映射规则可以是标准规定的或UE与网络设备事先约定好的，也可以是网络设备通过广播信道或其他下行信道发送给UE的，比如说，在终端设备传输上行数据失败时，可以接收网络设备发送的包括CTU重映射规则的消息，终端设备根据该CTU重映射规则确定用于进行重传的CTU，本发明对此不作限定。
举例来说，该新的CTU序号映射规则可以是从可选映射方案集合{fUE-TR(·)}中重新选取的一个新的映射规则。也可以是为UEi重新分配DCSi，根据当前采用的确定CTU序号的规则更新
Figure PCTCN2016087333-appb-000002
赋值，从而将UEi映射至新的CTU，为UEi提供新的CTU传输资源。还可以是部分地改变
Figure PCTCN2016087333-appb-000003
中一个或多个元素的赋值，从而为UEi提供部分新的CTU传输资源。但本发明并不限于此。
在本发明实施例中，可选地，如果UE与网络设备(例如，基站BS)双方约定以ACK方式确认接收检测成功，则网络设备在成功检测后将向UE发出ACK。如果UE在等待一定时间后未收到ACK，则认为上行传输发生冲突，网络设备未能成功接收上行数据。如果UE与网络设备双方约定以NACK方式确认接收检测失败，则网络设备在检测失败后将向UE发出NACK。如果UE接收到NACK，则认为上行传输发生冲突，网络设备未能成功接收上行数据。
应理解，在本发明实施例中，网络设备接收多个终端设备的上行Grant Free传输。网络设备根据ICTU与CTU接入区域的对应关系，以及ICTU与终端设备的DCS的对应关系，识别出进行Grant Free冗余传输的CTU，并在这些CTU上进行冗余接收。
在冗余接收过程中，针对UEi的接收检测ACK/NACK反馈不针对ICTU，ij指示的每一个CTU单独进行，而是在UEi冗余合并接收完成后做统一的ACK/NACK。
在本发明实施例中，可选地，在针对UEi进行冗余接收时，网络设备可以根据
Figure PCTCN2016087333-appb-000004
的指示，分别在相应CTU上进行信道估计、信号检测与解码，将解码成功的CTU上的信号比特进行合并，获得比特级合并接收增益，从而提升UEi的传输可靠性。网络设备还可以根据
Figure PCTCN2016087333-appb-000005
的指示，分别在相应CTU上进行信道估计，然后用各CTU信道估计结果以及各接收信号做联合检测，获得合并接收增益输出比特信息，从而提升UEi的传输可靠性。但本发明并不限于此。
举例来说，如图5(a)所示，UE1和UE2映射至CTU502，UE1和UE5映射至CTU510，因此CTU502与CTU510上均存在上行传输冲突。为解决Grant Free传输冲突，可将相应CTU上信号模型描述为如下线性方程组(1)：
Figure PCTCN2016087333-appb-000006
其中，y1为CTU502上的接收信号模型，y2为CTU506上的接收信号模型，y3为CTU510上的接收信号模型，y4为CTU512上的接收信号模型。Xj表示UEj发出的信号，Hij表示UEj至yi的信道信息，ni表示yi接收到的噪声。
从该线性方程组(1)中的两个独立的方程(2)：
Figure PCTCN2016087333-appb-000007
中解得X5和X2的估计值
Figure PCTCN2016087333-appb-000008
和
Figure PCTCN2016087333-appb-000009
然后根据估计值从剩余两个方程中消去X5和X2，使之转化为求解方程(3)：
Figure PCTCN2016087333-appb-000010
也就是说，为解决Grant Free传输冲突，可以首先从没有发生冲突的CTU506和CTU512上分别解出UE5和UE2的信息，然后利用已解得的信息从CTU502和CTU510上分别消除UE2和UE5对UE1的干扰，从而最终解得UE1。
可选地，在图5(b)中，UE1和UE2映射至CTU502，UE1和UE5映射至CTU510，因此CTU502与CTU510上均存在冲突。为解决Grant Free传输冲突，可将相应CTU上信号模型描述为线性方程组(4)：
Figure PCTCN2016087333-appb-000011
其中，y1为CTU502上的接收信号模型，y2为CTU506上的接收信号模型，y3为CTU510上的接收信号模型。Xj表示UEj发出的信号，Hij表示UEj至yi的信道信息，ni表示yi接收到的噪声。
可以先从独立方程y2＝h25x5+n2中解得X5的估计值
Figure PCTCN2016087333-appb-000012
然后根据估计值从y3中消去X5，并从y3＝h31x1+n3中解得X1的估计值
Figure PCTCN2016087333-appb-000013
最后根据估计值从y1中消去X1，并从y1＝h12x2+n1中解得X2的估计值
Figure PCTCN2016087333-appb-000014
也就是说，为解决Grant Free传输冲突，可以首先从没有发生冲突的CTU506上解出UE5的信息，然后利用已解得的UE5信息从CTU510上消除UE5对UE1的干扰，从而解出UE1的信息，最后利用已解得的UE1信息从CTU502上消除UE1对UE2的干扰，并最终解得UE2。
在本发明实施例中，如图5(a)和5(b)所示，UE3分别映射至CTU504和CTU514，且没有其它终端设备冲突，其接收信号模型可以表示为公式(5)：
Figure PCTCN2016087333-appb-000015
其中，y5为CTU504上的接收信号模型，y6为CTU514上的接收信号模型，Hij表示UEj至yi的信道信息，ni表示yi接收到的噪声。
另一方面，经过解决冲突后针对UE1的接收模型为公式(3)：
Figure PCTCN2016087333-appb-000016
由此可见，Grant Free冗余传输为相应UE提供了额外的自由度以提升传输可靠性。
下面将结合具体的例子详细描述本发明实施例，应注意，这些例子只是为了帮助本领域技术人员更好地理解本发明实施例，而非限制本发明实施例的范围。
