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,提出了上行的免授权(Grant Free)传输的一种方案。Grant Free传输可以理解为一种基于竞争的上行业务数据传输,与无线局域网络(Wireless Local Area Network,WLAN)的数据传输、以及长期演进LTE(Long Term Evolution,)系统中现有的随机接入过程有本质的区别。然而,Grant Free传输还没有一种网络设备获得使用Grant Free传输资源的许可的机制。

还应理解,本发明实施例的技术方案还可以应用于各种基于非正交多址接入技术的通信系统,例如稀疏码多址接入(Sparse Code Multiple Access,简称为“SCMA”)系统,当然SCMA在通信领域也可以被称为其他名称;进一步地,本发明实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统,例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing,简称为“OFDM”)、滤波器组多载波(Filter Bank Multi-Carrier,简称为“FBMC”)、通用频分复用(Generalized Frequency Division Multiplexing,简称为“GFDM”)、滤波正交频分复用(Filtered-OFDM,简称为“F-OFDM”)系统等。
本发明结合终端设备描述了各个实施例。终端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,终端设备可以指用户设备(User Equipment,简称为“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,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,未来5G网络中的终端设备等。

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。
下一代移动通信系统将不仅支持传统的通信,还将支持机器到机器(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:(I)可靠传输,但对时延不敏感;(II)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(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。
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。

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,本发明提出了上行的免授权(Grant Free)传输的一种方案。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::
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,如混合自动重传请求(Hybrid Automatic Repeat reQuest,简称为“HARQ”)机制等。
竞争传输单元(Contention Transmission Unit,简称为“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。
终端设备104-114在接入网络设备102之后,可以向网络设备102上报自身的能力信息,其中,该能力信息可以包括用于指示是否具有上行的免授权传输的能力的信息。这样,网络设备102可以根据各个终端设备上报的能力信息,采用上行的免授权传输机制或传统的请求-授权机制与终端设备进行通信。可选地,网络设备102可以通知终端设备进行上行的免授权传输的必要信息,例如该网络设备102可以指示终端设备进行上行的免授权传输,向终端设备发送搜索空间信息、CAR信息、CTU信息、调制编码方式信息,等等,其中,每个终端设备被映射到一个或多个CTU,该映射规则可以预定义或者由网络设备配置。终端设备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,但本发明实施例对此不做限定。应理解,本发明实施例还可以应用于除图1之外的其它通信系统,本发明实施例对此不做限定。
图2示例性地示出了四个CAR 202-208,其中,系统可用带宽被分成了多个不同的时间频率区域,每个CAR占用不同的资源块,其中,可选地,每个CAR占用的资源块的数量可以预定义,例如,CAR 202占用频带的资源块(Resource Block,简称为“RB”)1-4。如图2所示,每个CAR可以进一步划分成至少一个CTU,其中,每个CTU是特定时间、频率、签名和导频的组合,图2中每个CAR对应相同的CTU映射关系,这里为了说明,从不同的角度分别示出四个CAR的映射关系,但本发明实施例不限于此。如图2所示,每个CAR支持6个签名(S1-S6),每个签名可以对应于6个导频,因此共构成36个导频(P1-P36),对应36个CTU,但本发明实施例不限于此。
应理解,图2示例性地示出了四个CAR并且每个CAR包括36个CTU,但本发明实施例还可以包括其它数量的CAR并且每个CAR可以包括其它数
量的CTU,本发明实施例对此不做限定。
应理解,本发明实施例的免授权传输资源即为上文中所述的免授权传输的传输资源。
图3示出了本发明实施例的用于上行数据传输的方法300。该方法300由终端设备执行,方法300包括:
S310,终端设备向网络设备发送用于请求免授权传输资源的信息;
S320,该终端设备接收该网络设备发送的资源指示信息,该资源指示信息用于指示该网络设备根据该用于请求免授权传输资源的信息,为该终端设备分配的免授权传输资源;
S330,该终端设备根据该资源指示信息,确定进行免授权传输的传输资源。
因此,本发明实施例的用于上行数据传输的方法,终端设备向网络设备发送用于请求免授权传输资源的信息,接收该网络设备发送的资源指示信息,在网络设备为终端设备分配的免授权传输资源上,终端设备可以进行上行数据传输,从而实现基于竞争的上行数据传输,提高系统传输数据的效率。
具体而言,在本发明实施例的S310中,终端设备可以通过明示的方式来请求免授权传输资源,例如可以通过发送资源请求信息,从网络设备获得使用上行的免授权传输资源的许可。例如,终端设备可以通过在随机接入过程的第三个步骤(第三个步骤发送的消息Mesg3)中,发送无线资源控制(Radio Resource Control,简称为“RRC”)信令来发送资源请求信息,也可以通过在随机接入过程的的第三个步骤中,发送介质访问控制(Media Access Control,简称为“MAC”)信令发送资源请求信息。
应理解,在本发明实施例中,终端设备也可以通过发送单独的消息来请求免授权传输资源,还可以通过在随机接入的第一个步骤中通过隐示的方式来请求免授权传输资源,例如,以特定的随机接入前导序列、或者以特定的随机接入信道发送随机接入前导序列,或者上述特定的随机接入前导序列和特定的随机接入信道的组合,来请求免授权传输资源,本发明实施例对发送用于请求免授权资源的信息的具体形式不作限定。
在S320和S330中,网络设备在接收到终端设备发送的信息后,为终端设备分配免授权传输资源,并向终端设备发送资源指示信息。终端设备在该免授权传输资源上,可以进行上行数据传输。其中,该资源指示信息包括用
于指示免授权传输资源的时域位置的信息、频域位置的信息、码域位置的信息和导频信息中的一种或多种的组合。
例如,网络设备可以确定频域范围和时域范围作为免授权传输资源供该终端设备使用;也可以确定频域范围供该终端设备使用,该终端设备在该频域范围的任何时间都可以进行免授权传输;还可以确定时域范围供该终端设备使用,该终端设备在该时域范围的任何频带上都可以进行免授权传输。或者,网络设备还可以为终端设备分配码域资源或导频。资源指示信息中可以包括上述资源中的一种或多种的组合。应理解,网络设备为该终端设备分配的免授权传输资源可以为一个也可以为多个,本发明实施例对此不作限定。
具体地,资源指示信息可以包括无线帧、子帧、符号、子载波、资源块的信息,还可以包括天线、波束、码组等信息。可选地,本发明实施例中,资源指示信息可以包括频域位置的信息,或者更具体为频域位置的索引,这里的频域位置可以是免授权传输资源在频域上占用的子带的位置。例如,可以是正交频分复用(Orthogonal Frequency Division Multiplexing,简称为“OFDM”)系统中的子带,或者是滤波的正交频分复用(Filter Orthogonal Frequency Division Multiplex,简称为“F-OFDM”)系统中的子带,也可以是其它系统中的子带,本发明实施例对此不作限定。
在本发明实施例中所涉及的F-OFDM的技术,可以将频谱分成多个子带,一个子带有一套子带的参数(参数英文可以为numerology),。不同子带的参数(numerology)可以相同,也可以不同。子带的参数可以包括子载波间隔、传输时间间隔(Transmission Time Interval,TTI)长度、符号长度、符号数,以及循环前缀(Cyclic Prefix,CP)长度等参数中的至少一种。子带的参数可以是预先配置的,也可以根据业务负载的情况灵活的适配。不同类型的业务可以使用不同的子带。比如:传统语音/视频、物联网(Internet of Things,IOT)、实时车联网、多媒体广播多播业务(Multimedia broadcast multicast service,MBMS)分别分布在不同的子带中。
用于进行免授权传输的所有资源可以以表或数组等形式配置在网络设备和各终端设备中,资源指示信息中以索引或标识等,通知该终端设备为其分配的免授权传输资源。优选地,该资源指示信息包免授权传输资源的索引、免授权传输资源的时域位置的索引、免授权传输资源的频域位置的索引、免授权传输资源的码域位置的索引和免授权传输资源的导频的索引中的一种
或多种的组合。
在本发明实施例中,S310终端设备向网络设备发送用于请求免授权传输资源的信息,可以包括:该终端设备在随机接入的第三个步骤向网络设备发送资源请求信息,以用于请求免授权传输资源。换而言之,终端设备在随机接入的第三个步骤向网络设备发送的消息3(Msg3)中携带资源请求信息,以用于请求免授权传输资源。本发明实施例不改变现有的随机接入过程的基本的步骤,在随机接入过程的步骤中发送消息时增加免授权传输资源的相关信息,因而与现有的随机接入过程有很好的兼容性。
在本发明实施例中,资源请求信息除了用于终端设备向网络设备请求免授权传输资源,进一步地,该资源请求信息还可以包括传输特性信息,其中,该传输特性信息用于指示该终端设备的免授权传输资源的传输特性。例如,该传输特性信息可以包括时延特性信息、功耗特性信息和传输时间间隔TTI特性信息中的至少一种。
具体而言,不同的终端设备在不同的情况下,有可能需要使用不同性能的免授权传输资源进行上行数据传输。例如,当终端设备传输实时控制指令等要求极低时延的业务数据时,需要使用TTI短的免授权传输资源;而当终端设备的发射功率较低或无线信道条件较差或是传输无线抄表等时延不敏感的业务数据时,则需要使用TTI长的免授权传输资源。这就要求终端设备从网络设备获得的免授权传输资源的许可,要适合其Grant Free业务的特性要求。
在一个例子中,系统可以设置不同类型的免授权传输资源,例如普通的免授权传输资源以及低时延的免授权传输资源。终端设备要求进行极低时延的业务数据传输时,通过传输特性信息将该要求告知网络设备,从而获取低时延的免授权传输资源;否则,终端设备要求普通的免授权传输资源,或者对免授权传输资源的传输特性不做要求,此时网络设备为其分配普通的免授权传输资源。
因此,本发明实施例的终端设备发送传输特性信息告知网络设备其Grant Free业务传输的特性要求,例如低时延/短TTI的Grant Free传输、低功率/长TTI的Grant Free传输等。网络设备在收到该信息后,调度合适的免授权传输资源供该终端设备使用。
应理解,本发明实施例中的传输特性信息不限于时延特性信息、功耗特
性信息和传输时间间隔TTI特性信息等,还可以包括其它类型的对传输特性的需求信息,本发明实施例对此不作限定。
在本发明实施例中,可选地,该资源请求信息包括终端设备标识,以便于该网络设备根据该终端设备标识解决多个终端设备的竞争冲突。网络设备接收到终端设备发送的资源请求信息后,根据资源请求信息中的终端设备标识或用户标识,为不同的终端设备分配不同的免授权传输资源,并向用户发送资源指示信息,以解决多用户同时接入的竞争冲突。
在一个具体的例子中,终端设备可以通过随机接入过程的第三个步骤,从网络设备获取免授权传输资源。随机接入的具体过程如图4所示,包括:
S410,第一个步骤,终端设备选择一个随机接入前导序列,通过随机接入信道(Random Access Channel,简称为“RACH”),向网络设备发送该随机接入前导序列,以通知网络设备有一个随机接入请求,同时使得网络设备可以估计该终端设备的上行定时偏差。
S420,第二个步骤,网络设备在RACH检测到随机接入前导序列之后,向终端设备发送随机接入响应,告知终端设备其检测到的随机接入前导序列及其所在RACH的信息,通知终端设备调整UL定时偏差,并为终端设备调度在第三个步骤中用于发送Msg3的UL资源。
S430,第三个步骤,终端设备在接收到与自身发送的随机接入前导序列相匹配的随机接入响应之后,使用其所调度的UL资源,发送Msg3,Msg3中包括向网络设备请求免授权传输资源的资源请求信息。该资源请求信息可以通过RRC信令或MAC信令发送,指示了该终端设备需要进行上行的免授权传输,或者指示了该终端设备支持上行的免授权传输。该资源请求信息可以进一步指示,该上行的免授权传输的特性要求。例如,资源请求信息还可以包括用于指示该终端设备的免授权传输资源的传输特性的传输特性信息。例如,该传输特性信息包括时延特性信息、功耗特性信息和传输时间间隔TTI特性信息中的至少一种。
在一种实现中,终端设备仅在Msg3中发送用于向网络设备请求免授权传输资源的资源请求信息,不发送用于请求授权传输资源(非竞争的上行传输资源)的RRC连接请求(RRCConnectionRequest)。为了解决多终端设备的竞争冲突,可以在携带资源请求信息的信令中同时携带终端设备标识的相关信息,也可以使用另外一个信令携带终端设备标识,本发明实施例对此不
作限定。
在另一种实现中,终端设备在Msg3中既发送用于向网络设备请求免授权传输资源的资源请求信息给网络设备,也发送RRCConnectionRequest给网络设备,以请求授权传输资源。
S440,第四个步骤,网络设备在接收到携带资源请求信息的信令后,根据检测出的终端设备标识,向该终端设备标识对应的终端设备发送Msg4确认信息,以解决多终端设备同时接入的竞争冲突;并向该终端设备发送用于指示免授权传输资源的资源指示信息,以使该终端设备能够进行上行的免授权传输。
在一种实现中(对应于S430的一种实现),网络设备在Msg4中仅发送用于指示免授权传输资源的资源指示信息给终端设备,而不发送授权传输资源的配置信息,例如RRC连接配置(RRCConnectionSetup)。在这种情况下,终端设备可以无需建立RRC连接,通过上行的免授权传输直接向网络设备发送业务数据。
在另一种实现中(对应于S430的另一种实现),网络设备在Msg4中既发送用于指示免授权传输资源的资源指示信息给终端设备,也发送RRCConnectionSetup给终端设备,以使得终端设备既能够使用免授权传输资源传输数据,也能够使用授权传输资源传输数据。优选地,终端设备可以使用免授权传输资源传输小包数据,使用授权传输资源传输大包数据,本发明实施例对此不作限定。本实现方式可以与现有的LTE系统中请求授权传输资源的方案很好的兼容。
应理解,网络设备向终端设备发送的资源指示信息以及RRCConnectionSetup等,可以通过Msg3中的RRC信令,也可以通过Msg3中的MAC信令,但本发明实施例并不限于此。
在本发明实施例中,可选地,S310终端设备向网络设备发送用于请求免授权传输资源的信息,包括:该终端设备通过无线资源控制RRC信令,向该网络设备发送用于请求免授权传输资源的资源请求信息。
具体而言,终端设备可以在向网络设备发送的RRC信令RRCConnectionRequest中,增加关于免授权传输资源请求的定义。例如,具体形式如下。其中,增加的定义为contentionAccess,表示终端设备请求免授权传输资源,contentionAccess-fast表示请求的免授权传输资源为短TTI的资
源。应理解,以上仅为举例,可以增加其它字段或定义以表明终端设备请求免授权传输资源,本发明对具体实现方式不作限定。
RRCConnectionRequest message
此外,终端设备还可以向网络设备新发送一条RRC信令来携带用于请

备和终端设备的约定特定随机接入配置可以通过标准规范实现,也可以通过发送消息(例如,网络设备向终端设备发送随机接入配置消息)来实现,本发明实施例对具体的实现方法不作限定。
可选地,作为一个实施例,S310终端设备向网络设备发送用于请求免授权传输资源的信息,包括:该终端设备通过发送第一随机接入前导序列,向该网络设备请求免授权传输资源,其中,该第一随机接入前导序列属于第一随机接入前导序列组,该第一随机接入前导序列组用于请求免授权传输资源,该第一随机接入前导序列组包括至少一个随机接入前导序列。
具体而言,终端设备在随机接入过程的第一个步骤,向网络设备发送随机接入前导序列。终端设备可以以特定的随机接入前导序列(例如,第一随机接入前导序列),向网络设备请求免授权传输资源。其中,网络设备和终端设备可以预先设定一组特定的随机接入前导序列(例如,为第一随机接入前导序列组),用于终端设备请求免授权传输资源。网络设备在接收到终端设备发送的第一随机接入前导序列后,检测第一随机接入前导序列对应的复数波形,可以确定该终端设备发送的第一随机接入前导序列是否属于第一随机接入前导序列组。当确定第一随机接入前导序列属于第一随机接入前导序列组时,可以确定终端设备在进行免授权传输资源的请求,网络设备为该终端设备分配免授权传输资源。
可选地,在本发明实施例中,在该终端设备通过发送第一随机接入前导序列,向该网络设备请求免授权传输资源之前,该方法300还包括:该终端设备从多个随机接入前导序列组中选择该第一随机接入前导序列组的该第一随机接入前导序列,该多个随机接入前导序列组至少包括该第一随机接入前导序列组和第二随机接入前导序列组,该第二随机接入前导序列组用于请求授权传输资源。
具体而言,终端设备发送的第一随机接入前导序列是从多个随机接入前导序列组中选择出来的。系统将随机接入前导序列(例如,现有技术中包括64种随机接入前导序列)进行分组,例如分为第一随机接入前导序列组和第二随机接入前导序列组,第一随机接入前导序列组用于请求免授权传输资源,第二随机接入前导序列组用于请求授权传输资源。在终端设备需要请求免授权传输资源时,该终端设备从多个随机接入前导序列组中选择第一随机接入前导序列组的第一随机接入前导序列,发送给网络设备。应理解,系统可以
将随机接入前导序列分为更多的随机接入前导序列组,而不限于上述例子中的两组。
当网络设备确定第一随机接入前导序列属于第一随机接入前导序列组时,可以确定终端设备在进行免授权传输资源的请求,网络设备为该终端设备分配免授权传输资源。当网络设备确定第一随机接入前导序列不属于第一随机接入前导序列组时,例如属于第二随机接入前导序列组(对应与授权传输资源的请求)时,可以确定终端设备在进行授权传输资源的请求,网络设备为该终端设备分配授权传输资源。
在本发明实施例中,该第一随机接入前导序列组包括M个第一随机接入前导序列子组,该M个第一随机接入前导序列子组是根据传输特性来划分的。其中,该传输特性可以包括时延特性、功耗特性和传输时间间隔TTI长度特性中的一种或多种,还可以包括其它的一些用于指示免授权传输资源的性能的特性或参数等,本发明实施例对此不作限定。
进一步地,网络设备和终端设备可以约定多个不同的随机接入前导序列子组,来对应不同类型的免授权传输资源的请求。例如,可以将第一随机接入前导序列组分为多个(例如,M个)随机接入前导序列子组,包括第一随机接入前导序列子组、第二随机接入前导序列子组等,不同的随机接入前导序列子组对应不同的传输特性的免授权传输资源。应理解,随机接入前导序列子组的个数可依据对免授权传输资源的传输性能的分类决定,本发明实施例对随机接入前导序列子组的个数不作限定。换而言之,终端设备根据对免授权传输资源的传输特性的需求,以及免授权传输资源的传输特性与随机接入前导序列子组的映射关系,确定与该需求对应的随机接入前导序列子组;该终端设备向该网络设备发送与需求对应的随机接入前导序列子组中的随机接入前导序列。
类似地,作为一个实施例,S310终端设备向网络设备发送用于请求免授权传输资源的信息,包括:该终端设备通过在第一随机接入信道上发送随机接入前导序列,向该网络设备请求免授权传输资源,其中,该第一随机接入信道属于第一随机接入信道组,该第一随机接入信道组用于请求免授权传输资源,该第一随机接入信道组包括至少一个随机接入信道。
在本发明实施例中,在该终端设备通过在第一随机接入信道上发送随机接入前导序列之前,该方法300还包括:该终端设备从多个随机接入信道组
中选择该第一随机接入信道组的该第一随机接入信道,该多个随机接入信道组至少包括该第一随机接入信道组和第二随机接入信道组,该第二随机接入信道组用于请求授权传输资源。
具体而言,终端设备用于发送随机接入前导序列的随机接入信道是从多个随机接入信道组中选择出来的。系统将随机接入信道进行分组,例如分为第一随机接入信道组和第二随机接入信道组,第一随机接入信道组用于请求免授权传输资源,第二随机接入信道组用于请求授权传输资源。在终端设备需要请求免授权传输资源时,该终端设备从多个随机接入信道组中选择第一随机接入信道组的第一随机接入信道,在该信道上发送随机接入前导序列。应理解,系统可以将随机接入信道分为更多的随机接入信道组,而不限于上述例子中的两组。
在本发明实施例中,第一随机接入信道组包括N个随机接入信道子组,该N个随机接入信道子组是根据传输特性来划分的。具体而言,系统可以将用于请求免授权传输资源的第一随机接入信道组进一步划分,划分为N个随机接入信道子组,以对应不同传输特性的免授权传输资源。终端设备根据对免授权传输资源的传输特性的需求,以及免授权传输资源的传输特性与随机接入信道的映射关系,确定用于发送该随机接入前导序列的与需求对应的随机接入信道;该终端设备在与需求对应的随机接入信道上,向该网络设备发送该随机接入前导序列。
类似地,作为一个实施例,S310终端设备向网络设备发送用于请求免授权传输资源的信息,包括:该终端设备通过在第一随机接入信道上发送第一随机接入前导序列,向该网络设备请求免授权传输资源,其中,该第一随机接入信道和第一随机接入前导序列的组合属于第一组合集合,该第一组合集合用于请求免授权传输资源,该第一组合集合包括至少一个随机接入信道和随机接入前导序列的组合。
在本发明实施例中,在该终端设备通过在第一随机接入信道上发送第一随机接入前导序列之前,该方法300还包括:该终端设备从多个组合集合中选择第一组合集合的该第一随机接入信道和第一随机接入前导序列的组合,该多个组合集合至少包括该第一组合集合和第二组合集合,该第二组合集合用于请求授权传输资源。其中,该第一组合集合包括K个组合子集,该K个组合子集是根据传输特性来划分的。本发明实施例的具体实施方式与前文
中描述的,以属于特定的随机接入前导序列组的随机接入前导序列或者以用于发送随机接入前导序列的特定的RACH来请求免授权传输资源的原理相类似,在此不再进行赘述。
在一个具体的例子中,终端设备可以通过发送随机接入前导序列,从网络设备获取免授权传输资源。具体过程如图5所示,包括:
S510,终端设备采用特定的随机接入配置,向网络设备发送随机接入前导序列,以用于请求免授权传输资源。其中,特定的随机接入配置用于告知网络设备终端设备需要进行上行的免授权传输,或者告知网络设备终端设备可以支持上行的免授权传输。其中,特定的随机接入配置可以是上文中描述的三种中的一种。
S520,网络设备在RACH接收到随机接入前导序列之后,检测随机接入前导序列,确定终端设备请求免授权传输资源。网络设备检测其随机接入配置,包括随机接入前导序列所属的随机接入前导序列组,终端设备发送随机接入前导序列使用的RACH,或者上述二者的组合。如果发现其符合与免授权传输资源请求相对应的特定的随机接入配置,则发送随机接入响应,告知终端设备其检测到的随机接入前导序列及其所在RACH的信息。随机接入响应中包括资源指示信息,以使该终端设备能够使用资源指示信息中的资源进行上行的免授权传输。
相应地,本发明实施例的方法相对于现有的发送随机接入前导序列不论是在RRC信令方面还是MAC层方面都有相应的变化。下面,以特定的随机接入配置为随机接入前导序列所属的随机接入前导序列组对应于免授权传输资源请求为例进行说明。具体而言,相对于现有的64个随机接入前导序列对应的随机接入前导序列组仅有A、B两组,本发明实施例的方法可以将64个随机接入前导序列分别定义至更多的组中。在RRC信令方面,RACH-ConfigCommon用于指定通用随机接入参数,其具体定义如下。其中,sizeOfRA-PreamblesGroupC ENUMERATED{n1,n2,n4,n8}用于定义新的随机接入前导序列组。
RACH-ConfigCommon information element
MAC层过程定义则包括随机接入过程的初始化和随机接入资源选择两部分。
(一)随机接入过程的初始化
如果sizeOfRA-PreamblesGroupA+sizeOfRA-PreamblesGroupC等于numberOfRA-PreamblessizeOfRA则不存在随机接入前导序列B组。随机接入前导序列A组中的前导序列是0至sizeOfRA-PreamblesGroupA-1,随机接入前导序列C组中的前导序列是从sizeOfRA-PreamblesGroupA到sizeOfRA–PreamblesGroupC-1。如果随机接入前导序列B组存在,在随机接入前导序列B组中的前导序列是预定义的64个前导序列中的sizeOfRA-PreamblesGroupC到numberOfRA-Preambles-1。
If sizeOfRA-PreamblesGroupA+sizeOfRA-PreamblesGroupC is equal to numberOfRA-PreamblessizeOfRA then there is no Random Access Preambles group B.The preambles in Random Access Preamble group A are the preambles0to sizeOfRA-PreamblesGroupA–1,the preambles in Random Access Preamble group C are from sizeOfRA-PreamblesGroupA to sizeOfRA-PreamblesGroupC–1and,if it exists,the preambles in Random Access Preamble group B are the preambles sizeOfRA-PreamblesGroupC to numberOfRA-Preambles–1from the set of 64preambles.
(二)随机接入资源选择
如果RA-PreambleIndex(随机接入前导序列)和RA-PRACH-MaskIndex(PRACH掩码索引)已被明确告知,并且RA-PreambleIndex不是000000:
-随机接入前导序列和PRACH掩码索引是已被明确告知的。
否则,随机接入前导序列由UE选择如下:
-如果消息3尚未被发送,则UE应当:
-如果随机接入前导序列C组存在,并且由上层指示要使用,则:
-选择随机接入前导序列C组;
-如果随机接入前导序列B组存在,并且潜在消息大小(数据可用于传输附加的MAC报头,以及需要的MAC控制元素)大于messageSizeGroupA,并且如果路损比PCMAX,c(服务小区执行随机接入过程的PCMAX,c)-preambleInitialReceivedTargetPower-deltaPreambleMsg3-
messagePowerOffsetGroupB少,则:
-选择随机接入前导序列B组;
-否则:
-选择随机接入前导序列A组。
If ra-PreambleIndex(Random Access Preamble)and ra-PRACH-MaskIndex(PRACH Mask Index)have been explicitly signalled and ra-PreambleIndex is not000000:
-the Random Access Preamble and the PRACH Mask Index are those explicitly signalled.
-else the Random Access Preamble shall be selected by the UE as follows:
-If Msg3has not yet been transmitted,the UE shall:
-if Random Access Preambles group C exists and is indicated by upper layers to be used,then:
-select the Random Access Preambles group C;
-if Random Access Preambles group B exists and if the potential message size(data available for transmission plus MAC header and,where required,MAC control elements)is greater than messageSizeGroupA and if the pathloss is less than PCMAX,c(of the Serving Cell performing the Random Access Procedure)–preambleInitialReceivedTargetPower–del-taPreambleMsg3–messagePowerOffsetGroupB,then:
-select the Random Access Preambles group B;
-else:
-select the Random Access Preambles group A.
应理解,以随机接入前导序列C组上仅为举例,可以增加更多的随机接入前导序列组以用于区分不同的免授权传输资源的传输特性,本发明对具体实现方式不作限定。
相应地,随机接入的流程也定义为两个步骤。第一个步骤为:终端设备向网络设备发送随机接入前导序列,以随机序列前导所属的随机接入前导序列组来区分请求的是否免授权传输资源;第二个步骤为:网络设备向终端设备发送随机接入响应。具体地,可以为:
The two steps of the contention based random access procedures are:
1)Random Access Preamble on RACH in uplink:
-The preamble group C is used.
2)Random Access Response generated by MAC on DL-SCH:
-……
-Conveys at least RA-preamble identifier,Timing Alignment information for the pTAG,UL grant for contention based data transmissions…….
