Description

免授权传输方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种免授权传输方法和装置。
背景技术
在典型无线通信网络(比如，长期演进(Long Term Evolution，LTE)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，BS)控制。在该机制中，用户设备(User Equipment，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。
上述海量用户接入的免授权传输，由于允许多个UE在同一时频资源上竞争传输，因此会导致竞争冲突，降低免授权传输的可靠性。
因此，亟待一种方法，来提高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。
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。
应理解，本申请实施例的技术方案可以应用于各种通信系统，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、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)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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，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。
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终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
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UE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。
图1示出了应用本申请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。

本申请提出了免授权(Grant Free)传输的一种方案。Grant free传输可以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。Grant free传输可以针对的是上行数据传输。本领域技术人员可以知道，Grant free传输也可以叫做其他名称,比如叫做自发接入、自发多址接入、或者基于竞争的多址接入等。Grant Free传输可以理解为包括但不限于如下含义中的任意一种含义，或，多种含义，或者多种含义中的部分技术特征的组合：
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，不需要网络设备动态调度也可以理解为静态,和/或,半静态调度。其中，本申请实施例中提到的“A和/或B”可以表示A和B，或，A，或B，不再赘述。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，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，SCMA)码本组、低密度签名(Low Density Signature，LDS)组、CDMA码组等；上行导频资源；交织资源；信道 编码方式。
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。
竞争传输单元(Contention Transmission Unit，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、导频序列相结合的传输，或者，可以指时间、频率、码域、导频序列相结合的传输资源；或者，可以指时间、频率、码域、导频序列、交织图样相结合的传输资源；或者，可以指时间、频率、码域、导频序列、信道编码方式相结合传输的资源；或者，可以指时间、频率、码域、导频序列、交织图样、信道编码方式相结合传输的资源。其中，CTU对应的码域资源可以对应包括本申请实施例提到的码分多址编码方法。
当然，CTU还可以是以上提到的各种资源的其他任意组合方式，为了简洁，不再一一列举。有关于CTU的介绍另一篇专利申请PCT/CN2014/073084申请内容也可以理解为通过引用作为本申请实施例内容的一部分作为补充参考，但本专利申请实施例保护范围不限于PCT/CN2014/073084描述内容。
在本申请实施例提到的交织图样集合可以包括各种用于区分用户的交织图样。
可选地，在本申请实施例中，交织图样集合中不同的交织图样可以基于不同的交织器，可以是基于相同的交织器，但是对应不同的参数。
为了便于理解，以下描述根据本申请实施例的几种交织器的实现方式。
实现方式A
设定基交织矩阵的大小为L×K,，L和K可以为正整数，即L行K列。将LK个输入比特{b0,b1,…,bLK-1}按照如下表1的顺序排列：
表1
b0 bL … bLK-L
b1 bL+1 … bLK-L+1
… … … …
bL-1 b2L-1 … bLK-1
按行输出交织后的比特：b0,bL,…,bLK-L,b1,…,bLK-L+1,…,bL-1,…,bLK-1。不同的交织图样可以是对基交织矩阵的不同列排列，即改变基交织矩阵各列的顺序。假设终端设备k排列前的矩阵为
Figure PCTCN2017083085-appb-000010
i＝1,...,L,j＝1,...K，对应的列排列为πk，其中πk(j)表示第j列在排列后的列序号。经过列排列后矩阵为
Figure PCTCN2017083085-appb-000011
其中
Figure PCTCN2017083085-appb-000012
其中，交织图样πk(j)＝mod(π(j)+ak,K),j＝0,...,K-1实现；
其中，ak＝mod(n，K)；
或，

应理解，在该种实现方式中，也可以按行输入比特，并按列输出交织后的比特；或按行输入比特，并按行输出交织后的比特；或按列输入比特，并按列输出交织后的比特。
实现方式B
在该种实现方式中，可以采用Turbo码内交织器。交织可以通过以下公式实现：
πi(x)＝mod(ak+f1x+f2x2，K)，x＝0，...，K-1
其中，所述K为待传输比特块大小，K可以为正整数，f1和f2的取值为所述K相关，ak表示对输入比特进行循环移位的次数，x表示输入比特的序号，ak表示对输入比特循环移位的次数，πi(x)表示输入比特在交织后进行输出的序号；
其中，ak＝mod(n，K)；
或，
Figure PCTCN2017083085-appb-000015
或，
Figure PCTCN2017083085-appb-000016
其中，N是所述终端设备的小区标识、n是所述终端设备的标识n，m是帧号或时隙编号(终端设备待传输数据或上次传输数据所占用的子帧或时隙的编号)，d是子带编号(终端设备待传输数据或上次传输数据所占用的子带的编号)。
可选地，参数f1和f2取决于编码块大小K，其中，f1和f2的取值可以通过查找以下表2获取。

在本申请实施例中，信道编码可以例如为LTE系统中的Turbo码编码，咬尾卷积码编码等。根据用户QoS要求的不同，可以选择不同的码率的编码方法进行信道编码。对于免授权传输，可以针对一类业务使用相同的编码方法和码率。
可选地，本申请实施例提到的码分多址编码方法可以是一种码域多址方式，可以采用ZC码、PN码和稀疏码本(例如SCMA码本)或者其他的码进行码分多址编码。

具体地说，SCMA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。
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，本申请并不限定于此，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。
当然，本申请实施例的码分多址编码方法还可以对应多用户共享接入(multi-user shared access，MUSA)码或其他稀疏扩频码。其中，该MUSA码可以通过使用随机非正交复杂扩频码支持免授权传输和高用户负荷。

可选地，网络设备可以广播可选择的多个CTU，每个CTU包括码分多址编码方法、导频序列、时频资源和交织图样，其中，不同的CTU可以至少有一个维度不同，例如交织图样不同，从而可以通过交织图样的不同，可以尽量避免由于多个终端选择相同的时频资源所造成的无法区分终端而导致的数据解码失败的问题。
可选地，终端设备可以基于索引，从多个CTU中选择CTU。可选地，可以基于随机数发生器生成该索引，其中，该随机数发生器的初值为该终端设备的标识、系统帧号、时隙编号和小区标识中的至少一种。其中，系统帧号和时隙编号可以是当前用于发送数据的帧的帧号和时隙的编号，小区标识可以是终端设备所在的小区的标识。
可选地，在本申请实施例中，CTU和元素集合(例如，码分多址编码方法集合或交织图样集合)可以同时存在。例如，CTU包括码分多址编码方法、时域资源和频域资源，而交织图样可以从交织图样集合中选择。
可选地，在CTU和元素集合同时存在时，可以采用同一索引选择CTU和从元素集合中选择元素，也可以采用不同的索引选择CTU和从元素集合中选择元素。
