Description

信息传输装置、方法以及无线通信系统 技术领域
本发明涉及通信技术领域,特别涉及一种信息传输装置、方法以及无线通信系统。
背景技术
在长期演进(LTE,Long Term Evolution)系统中,控制信息的应用比较广泛。从协议架构来看,在无线资源控制(RRC,Radio Resource Control)层,控制信息可包括用于辅助用户设备(也可称为终端)接入网络的系统信息(SI,System Information)以及RRC连接控制信息等。
在物理层,控制信息可包括用来传输重要系统信息的物理广播信道(PBCH,Physical Broadcast Channel),和用来指示调度信息的物理下行控制信道(PDCCH,Physical Downlink Control Channel)以及用来传输RRC信令的物理下行共享信道(PDSCH,Physical Downlink Shared Channel)。
通常情况下,PBCH携带系统信息中最重要的主信息块(MIB:Master Information Block)。例如在Rel.13协议中,PBCH包括以下重要信息:系统带宽,物理混合自动重传请求指示信道(PHICH,Physical Hybrid automatic repeat request Indicator Channel)的配置,系统帧号以及用于指示系统信息块(SIB,System Information Block)SIB1信息传输的调度信息。
表1示出了MIB的部分内容。
表1
Figure PCTCN2016090879-appb-000001
PBCH以40ms为周期进行发送,每个周期内,每10ms发送一个可以进行独立译码的MIB样本。在频域位置,PBCH占据和同步信道(包括主同步信号(PSS,Primary Synchronization Signal)/辅同步信号(SSS,Secondary Synchronization Signal))相同的系统载频中心的6个资源块(RB,Resource Block)。
图1是LTE系统的物理广播信道传输的一示意图。如图1所示,用户设备进行下行同步后,可以接收PBCH获得系统信息,然后监听PDCCH上的控制信息,用于后续数据的传输和接收。
通常来说,在每个子帧中,基站使用固定个数和位置的符号发送PDCCH,在频域上,基站可以使用系统带宽内所有的频率资源进行PDCCH传输。为了减少用户设备的盲检次数(尤其是针对大带宽系统),对于不同类型的PDCCH,例如发送小区通用控制信息的位于公共搜索空间(common search space)的PDCCH和发送特定用户设备的控制信息的位于专用搜索空间(UE-specific search space)的PDCCH,可以使用不同的频率资源,这样在特定的频率资源位置,只检测一个或者多个特定格式的PDCCH,从而减少了盲检次数。
另一方面,未来需要提供更加先进的无线通信技术,目前一些标准组织进行了未来无线通信系统的需求研究。例如,系统要支持大容量传输速率的通信方式,可称为增强的移动宽带(eMBB,enhanced mobile broadband);还要考虑对大量机器类型通信的支持,可称为海量机器类通信(mMTC,massive machine type communication);另外,考虑到自动驾驶、灾难场景应急通信等,还要能支持高可靠度以及低延迟的通信,可称为超可靠低时延通信(uRLLC,ultra-reliable low latency communication)。
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
但是,发明人发现:控制信息所占PDCCH的传输在LTE系统中是在全带宽资源上传输,而在未来超大带宽系统上,如果使用所有的全带宽资源进行PDCCH传输,将会导致用户设备侧巨大的盲检复杂度,即使按照公共搜索空间和专用搜索空间进一步划分这些资源,仍然会带来很大的盲检复杂度。为此,需要考虑在未来超大带宽和 多种制式(numerology)共存的系统下如何传输控制信息的问题。
本发明实施例提供一种信息传输装置、方法以及无线通信系统。期望在未来超大带宽和多种制式共存的系统下,可靠地传输控制信息并降低接收复杂度。

具体实施方式
参照附图,通过下面的说明书,本发明的前述以及其它特征将变得明显。在说明书和附图中,具体公开了本发明的特定实施方式,其表明了其中可以采用本发明的原则的部分实施方式,应了解的是,本发明不限于所描述的实施方式,相反,本发明包括落入所附权利要求的范围内的全部修改、变型以及等同物。
在本申请中,基站可以被称为接入点、广播发射机、节点B、演进节点B(eNB)等,并且可以包括它们的一些或所有功能。在文中将使用术语“基站”。每个基站对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域,这取决于使用该术语的上下文。
在本申请中,移动站或设备可以被称为“用户设备”(UE,User Equipment)。UE可以是固定的或移动的,并且也可以称为移动台、终端、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、 手持设备、膝上型计算机、无绳电话等。
针对未来通信的三种不同的应用场景,为了简化设计,需要进行统一的系统设计。例如对于uRLLC应用(或者也可以称为业务)来说,需要尽可能低的传输时延,需要将符号长度降低,也即将子载波间隔拉长(如果采用类似OFDM设计的话);对于mMTC应用来说,数据传输速率不高,可以使用更长的符号,也即将子载波间隔降低;而对于eMBB应用来说,处于uRLLC和mMTC这两个应用的需求之间。
这三种不同业务使用的子载波间隔和符号长度等参数可能不同,一种子载波间隔和符号长度(以及其他参数等)可以称为一种制式(Numerology)。其他参数例如包括:循环前缀(CP,Cycle Prefix)长度,等等;但本发明不限于此。
为了保证系统设计的简单,可以尽量将多种Numerology下的时间间隔(例如子帧长度)设计成相同。
图2是本发明实施例的多种制式下的帧结构的一示意图,如图2所示,在某一时间间隔(例如一个子帧长度)内,时频资源可以有多种制式(如图2所示的制式1、制式2和制式3)。不同的Numerology下有不同的子载波间隔和符号长度,但子帧长度是相同的。在未来超大带宽系统下,多种Numerology可能共存,不同的Numerology可以占用独立的一段频率划分(frequency portion)或者共有一段频率划分。
以上对于制式进行了示意性说明;其中以不同制式具有不同的子载波间隔和/或符号长度为例,但本发明不限于此,例如不同制式还可以具有不同的其他参数。关于制式的名称,本发明并不对此进行限制,例如还可以称为模式、样式等等。
以下以将无线通信系统中的基站作为发送端、将用户设备作为接收端为例进行说明,但本发明不限于此,例如发送端和/或接收端还可以是其他的网络设备。
实施例1
本发明实施例提供一种信息传输方法,应用于使用多种不同制式的时频资源的无线通信系统中。图3是本发明实施例的信息传输方法的一示意图,如图3所示,所述信息传输方法包括:
步骤301,发送端通过一个物理广播信道向接收端发送多种不同制式对应的系统信息;其中,该物理广播信道在预先确定的频域资源和时域资源上被周期性地发送。
在本实施例中,该发送端可以为宏基站(例如eNB),接收端为用户设备;该宏 基站产生的宏小区(例如Macro cell)可以为该用户设备提供服务。或者,发送端也可以为微基站,接收端为用户设备;该微基站产生的微小区(例如Pico cell)可以为该用户设备提供服务。或者,发送端和/或接收端也可以为其他网络设备。本发明不限于此,可以根据实际的需要确定具体的场景。
在本实施例中,在存在多种Numerology的无线通信系统中,物理广播信道在固定的频域位置并周期性地发送。该固定的频率资源位置可以被预先约定,可以和同步信道占用相同大小的频率资源,或者也可以占用不同大小的频率资源位置;在时间上可以分时地周期发送。
通过固定发送物理广播信道的频域资源,可以方便用户设备在同步完成后接收系统消息。如果在不同的Numerology对应的系统资源上分别传输物理广播信道,将会增加用户设备的接收复杂度;为此,本发明将不同Numerology对应的系统信息统一在一个固定频域位置上发送,可以方便用户设备在该频域位置收到不同Numerology对应的系统信息,降低用户设备的接收复杂度。
此外,发送本发明实施例的物理广播信道的时域资源也可以被预先确定,即该物理广播信道在预先确定的频域资源以及时域资源上被周期性地发送。
在本实施例中,物理广播信道可以承载有多种不同制式的配置信息。所述制式的配置信息可以包括如下信息的其中一项或多项:带宽信息、频域资源信息、时域资源信息、波束标识(beam ID)相关信息。但本发明不限于此,还可以包括其他的信息。
例如,这些配置信息可以包括以下信息的一个或者多个:不同Numerology的带宽信息,频域资源信息、时域资源信息;此外还可以包括以下信息的一个或者多个:系统帧编号,SIB1的调度信息,beam ID相关信息等。其中,时域资源信息可以是该Numerology配置可以持续的时间信息。这些配置信息可以被携带在MIB中。
通过在物理广播信道中携带不同Numerology的配置信息,可以让用户设备通过物理广播信道获得各个Numerology的带宽、频域配置、时域配置(包括周期性或者非周期性的配置)等,以便用户设备在后续数据传输中选择合适的Numerology进行数据传输。
另外,在多天线系统中,通过在广播信道中携带beam ID或者与之相关的信息,以便于采用基于beam传输时获取该传输PBCH和其他物理信道(比如PDCCH,PDSCH等)所使用的beam标识。
又例如,如果用户设备将要进行eMBB的数据传输,在物理广播信道中获得了对应eMBB的Numerology的配置信息后,可以在要求的系统带宽和时间上进行eMBB的数据传输;对于uRLLC和mMTC业务,可以类似地进行处理。当然,多种不同业务的Numerology可以采用一组相同的配置信息,或者也可以采用不同的配置信息,具体可以取决于系统的设置。
在本实施例中,多种不同制式可以分别具有物理控制信道。其中,每一制式所对应的物理控制信道可以占用独立的时域资源和/或频率资源。所述制式所对应的物理控制信道的配置信息,可以通过所述物理广播信道被发送,和/或,也可以通过控制信令(例如RRC信令)被发送。
其中,物理控制信道的配置信息可以包括如下信息的其中一项或多项:物理控制信道所占频域位置信息、物理控制信道所占时域位置信息、公共搜索空间的物理控制信道的配置信息以及专用搜索空间的物理控制信道的配置信息。但本发明不限于此,还可以包括其他信息。
值得注意的是,物理控制信道可以是PDCCH,例如可以是LTE系统中的PDCCH或者ePDCCH,或者也可以是新定义的物理控制信道。本发明对此并不进行限制,还可以是其他的物理控制信道。
在一个实施方式中,多种不同制式可以在频域上被复用。
图4是本发明实施例的频域复用多种制式的一示意图,如图4所示,在一个时间间隔(TT,Time Interval)内可以具有制式1、制式2和制式3三种时频资源,其中每种制式分别具有物理控制信道。
如图4所示,当不同的Numerology以频分方式复用在不同的带宽资源上时,每个Numerology在所占的带宽资源上都可以有独立的物理控制信道,该物理控制信道所占时域资源信息(例如符号个数和/或位置等)和/或频域位置信息(例如所占的全部带宽资源,或者部分带宽资源等)可以通过物理广播信道通知给接收端(例如用户设备)。
在本实施例中,除了不同的Numerology采用频分复用的方式复用在系统的带宽资源上,还可以通过时分复用的方式来进行多种Numerology的通信,或者通过时分和频分联合复用的方式来进行多种Numerology的通信。
在另一个实施方式中,多种不同制式可以在时域上被复用。
图5是本发明实施例的时域复用多种制式的一示意图,如图5所示,在一个时间间隔内可以具有制式1的时频资源,在另一时间间隔内可以具有制式2的时频资源,其中每种制式分别具有物理控制信道。
如图5所示,不同的Numerology在不同的时间可以使用全部的频率资源,在每个Numerology的发送时间内,其物理控制信道的时域配置信息(例如符号个数和/位置)以及频域配置信息可以通过物理广播信道发送给接收端(例如用户设备)。
在本实施例中,当系统需要根据灵活地配置多个Numerology时,还可以采用时域和频域联合复用的方法。
在另一个实施方式中,多种不同制式可以在时域和频域上联合被复用。
图6是本发明实施例的时域和频域联合复用多种制式的一示意图,如图6所示,在一个时间间隔内可以具有制式1的时频资源,在另一时间间隔内可以具有制式1和制式2的时频资源,在另一时间间隔内可以具有制式1的时频资源;其中每种制式分别具有物理控制信道。
如图6所示,制式2占用了制式1的部分时频资源,在这种情况下,两种制式里的物理控制信道的配置信息可以在物理广播信道中发送。或者为了更加灵活地配置制式2的数据信道和控制信道资源,也可以在RRC信令中传输该制式2上用于传输控制信道的配置信息。
在本实施例中,接收端(例如用户设备)可以从固定的频域资源位置发送的物理广播信道接收到系统消息,可以获取各个Numerology的系统配置信息,以及各个Numerology的控制信道的配置信息,然后根据不同的业务需要,可以到相应的物理控制信道(例如PDCCH)接收控制信息进行数据传输。
由上述实施例可知,通过一个物理广播信道发送多种不同制式对应的系统信息;其中,所述物理广播信道在预先确定的频域资源和时域资源上被周期性地发送。由此,在未来超大带宽和多种制式共存的系统下,不仅可靠地传输控制信息,而且能够降低接收复杂度。
