Description

子帧指示方法及设备 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种子帧指示方法及设备。
背景技术
随着技术的不断发展,未来第五代移动通信(the 5th Generation Mobile Communication,5G)中,逐渐演变出自包含(self-contain)子帧。与长期演进(Long Term Evolution,LTE)中的上行子帧或下行子帧不同,自包含子帧在一个时间间隔(time interval)内,同时存在下行控制信令、上行控制信令、下行数据和/或上行数据。当自包含子帧中既存在下行控制信令,又存在上行数据时,下行控制信令(例如为上行调度信息)与上行数据之间存在一个间隔(Gap),该间隔用于上下行转换和用户设备(User Equipment,UE)准备上行数据。
图1为自包含子帧的结构示意图。请参照图1,该自包含子帧的符号从左至右依次被下行控制信令(如横线填充部分)、下行数据(如竖线填充部分)、间隔(如空白部分)、上行数据(如斜线填充部分)、上行控制信令(如方格填充部分)占用,示意出一种最基本的自包含子帧类型。实际中,可以对图1进行变形,得到其他类型的自包含子帧。例如,将间隔、上行数据和上行控制信令占用的符号变为0,则得到仅包含下行控制信令和下行数据的自包含子帧;再如,将下行控制信令、下行数据、间隔和上行控制信令占用的符号变为0,则得到仅包含上行数据的自包含子帧。通信过程中,需要由网络侧设备将自包含子帧的子帧类型指示给UE,使得UE根据子帧类型,判断出自包含子帧包含哪些部分,从而发送上行控制信令或上行数据,或者接收下行数据或下行控制信令。
然而,自包含子帧中,根据图1对基本类型进行变形,可以得到8种自包含子帧类型。进一步的,每种类型的子帧中,各部分占用的符号的数据是可变的,进而可以得到更多类型的自包含子帧,导致指示子帧类型的信令开销巨大。

具体实施方式
未来5G中的子包含子帧的结构如图1所示,对图1进行变形,可以得到7类型的子帧,即第一类型~第七类型(Type1~Type7),具体的,可参见图2,图2为对图1所示自包含子帧变形后得到的子帧类型结构示意图。将图1所示子帧类型记为第八类型(Type8),结合图1与图2,共有8中子帧类型。其中:Type1包括下行控制信息与下行数据,仅包括下行Type2包括下行控制信令、下行数据、间隔和上行控制信息;Type3包括下行控制信令、间隔与上行数据;Type4包括下行控制信令、间隔、上行数据与上行控制信令;Type5包括上行数据,而且仅包括上行;Type6包括上行数据、上行控制信令,也仅包括上行;Type7包括下行控制信令、下行数据、间隔、上行数据。
通信过程中,需要由网络侧设备将自包含子帧的子帧类型指示给UE, 使得UE根据子帧类型,判断出自包含子帧包含哪些部分,从而发送上行控制信令或上行数据,或者接收下行数据或下行控制信令。然而,自包含子帧中,根据图1对基本类型进行变形,可以得到8种自包含子帧类型。进一步的,每种类型的子帧中,各部分占用的符号的数据是可变的,进而可以得到更多类型的自包含子帧。
具体的,由于Type1~Type7均是Type8的变形,因此,对Type8进行分析可知:假设5G中的子帧与LTE子帧同样,一个子帧中包含14个符号,由于下行控制信令需要占用1、2或者3个符号,上行控制信令需要占用1或2个符号。则下行控制信令包含4种可能(0,1,2,3个符号),上行控制包含3种可能(0,1,2)个符号,间隔(Gap)包含2种可能(0,1个符号),除去第一个符号与最后一个符号,间隔可能的位置有12种,因此间隔包含13种可能(包含间隔占用0个符号的情况),间隔的位置不同也就区分了上行数据和下行数据的位置和大小。因此,所有子帧类型的种类为4×3×13=156种,若需要指示的话,则子帧指示信息需要8比特(bit),信令开销是非常巨大的。
有鉴于此,本发明实施例提供一种帧指示方法及设备,实现减少子帧指示信息开销的目的。
本文中描述的技术可用于各种存在多种类型终端的通信系统,例如全球移动通信系统(Global System for Mobile communications,GSM),码分多址(Code Division Multiple Access,CDMA)系统,时分多址(Time Division Multiple Access,TDMA)系统,宽带码分多址(Wideband Code Division Multiple Access Wireless,WCDMA),频分多址(Frequency Division Multiple Addressing,FDMA)系统,正交频分多址(Orthogonal Frequency-Division Multiple Access,OFDMA)系统,单载波FDMA(SC-FDMA)系统,通用分组无线业务(General Packet Radio Service,GPRS)系统,长期演进(Long Term Evolution,LTE)系统,E-UTRA系统、5G移动通信系统,以及其他此类通信系统。
本发明实施例中涉及的第一设备,例如为网络侧设备,其可以为基站、接入点(Access Point,AP)等。其中,基站可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与 IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者是5G基站,本申请并不限定。
本发明实施例中涉及的第二设备,例如为用户设备,可以是有线终端,也可以是无线终端,该无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如,RAN,Radio Access Network,5G RAN,non-3GPP RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
图3为本发明子帧指示方法所适用的系统架构示意图。请参照图3,本系统架构中,至少存在一个第一设备,以及至少一个第二设备,第一设备与各第二设备之间建立通信连接。下面,在图3的基础上对本发明实施例所述的子帧指示方法进行详细说明。具体的,可参见图4。
图4为本发明子帧指示方法实施例一的信令图,包括:
101、第一设备确定子帧指示信息。
本步骤中,第一设备确定出指示第一子帧中的至少一个部分的子帧指示信息,其中,子帧指示信息指示第一子帧的上行控制信令、下行控制信令和数据中的至少一个,数据包括上行数据、下行数据和/或间隔。例如,子帧指 示信息指示第一子帧的上行控制信令、下行控制信息和数据部分;再如,子帧指示信息指示第一子帧的上行控制信令和下行控制信令;又如,子帧指示信息指示第一子帧的数据部分;又如,子帧指示信息指示第一子帧的上行控制信令和数据部分;又如,子帧指示信息指示第一子帧的下行控制信令和数据部分;又如,子帧指示信息指示第一子帧的下行控制信令;又如,子帧指示信息指示第一子帧的上行控制信令。子帧指示信息在对第一子帧的各个部分进行指示,是指指示各个部分占用的符号数、时间长度或时域位置中的至少一个。其中,符号例如为正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号等,本发明并不限定。
102、第一设备向第二设备发送所述子帧指示信息。
在确定好子帧指示信息后,第一设备将子帧指示信息发送给第二设备。
103、所述第二设备根据所述子帧指示信息,确定所述第一子帧的子帧类型。
本步骤中,在接收到子帧指示信息后,第二设备根据该子帧指示信息确定第一子帧的子帧类型。例如,若子帧指示信息指示子帧的第一子帧的上行控制信令、下行控制信令和数据部分,则第二设备从第一子帧中确定第一子帧为Type2、Type4或Type8子帧类型,而且还可以根据各个部分占用的符号数、时间长度或时域位置,确定出子帧的具体类型。
本发明实施例提供的子帧指示方法,第一设备确定出指示第一子帧的上行控制信令、下行控制信令和数据中的至少一个部分的子帧指示信息,并将该子帧指示信息发送给第二设备,使得第二设备根据子帧指示信息确定第一子帧的类型。该过程中,第一设备仅需要将指示第一子帧的各个部分中的至少一个部分的子帧指示信息发送给第二设备,第二设备根据该子帧指示信息即可确定出第一子帧的类型,实现减少子帧指示信息开销的目的。
可选的,在本发明一实施例中,当所述子帧指示信息指示所述第一子帧的上行控制信令时,所述子帧指示信息指示所述第一子帧的上行控制信令占用的符号数、时间长度或时域位置。该种方式下,第一设备仅需要向第二设备指示第一子帧的上行控制信令,子帧指示信息开销小。
可选的,在本发明一实施例中,当所述子帧指示信息指示所述第一子帧的下行控制信令时,所述子帧指示信息指示所述第一子帧的下行控制信令占 用的符号数、时间长度或时域位置。该种方式下,第一设备仅需要向第二设备指示第一子帧的下行控制信令,子帧指示信息开销小。
可选的,在本发明一实施例中,当所述子帧指示信息指示所述第一子帧的数据时,所述子帧指示信息指示所述第一子帧的上行数据、下行数据、间隔中的至少一个部分。例如,当所述子帧指示信息指示所述第一子帧的下行数据时,所述子帧指示信息指示所述第一子帧的下行数据占用的符号数、时间长度或时域位置。再如,当所述子帧指示信息指示所述第一子帧的上行数据时,所述子帧指示信息指示所述第一子帧的上行数据占用的符号数、时间长度或时域位置。又如,当所述子帧指示信息指示所述第一子帧的间隔时,所述子帧指示信息指示所述第一子帧的间隔占用的符号数、时间长度或时域位置。该种方式下,第一设备仅需要向第二设备指示第一子帧的数据部分,子帧指示信息开销小。
上述实施例中,第一子帧的下行控制信令可以进行本子帧调度或跨子帧调度数据。具体的,可参见图5A、图5B、图5C与图5D,图5A本发明子帧指示方法中下行控制信令本子帧调度上行数据的示意图,图5B为本发明子帧指示方法中下行控制信令本子帧调度下行数据的示意图,图5C为本发明子帧指示方法中下行控制信令跨子帧调度上行数据的一个示意图,图5D为本发明子帧指示方法中下行控制信令跨子帧调度上行数据的另一个示意图,图5E为本发明子帧指示方法中下行控制信令跨子帧调度下行数据的示意图。
请参照图5A与图5B,第一子帧中的控制信令有多个,因此对于第一子帧来说,其可同时调度上行数据和下行数据,但对于一个下行控制信令来说,只能调度一种数据,即只能调度上行数据或下行数据。
请参照图5D,当第一子帧的下行控制信令跨子帧调度数据时,可以对第二子帧的下行数据进行调度。具体的,第一子帧的下行控制信令携带第一指示信息,所述第一指示信息指示所述第二设备接收第二子帧的下行数据。该种方式下,当第二设备接收到子帧指示信息后,根据第一指示信息,接收第二子帧的下行数据,实现跨子帧调度下行数据的目的。
请参照图5C,当第一子帧的下行控制信令跨子帧调度数据时,可以对第二子帧的上行数据进行调度。具体的,第一子帧的下行控制信令携带第 二指示信息,所述第二指示信息指示所述第二设备发送第二子帧的上行数据。该种方式下,当第二设备接收到子帧指示信息后,根据第二指示信息准备第二子帧的上行数据并发送,实现跨子帧调度上行数据的目的。
进一步的,当第一子帧的下行控制信令对第二子帧的上行数据进行调度时,第一子帧的下行控制信令还携带第三指示信息,所述第三指示信息指示所述第二子帧的上行数据占用的时域资源、符号数目和/或符号位置。该种方式下,当第二设备接收到子帧指示信息后,根据第二指示信息和第三指示信息准备第二子帧的上行数据并发送,实现跨子帧调度上行数据的目的。
上述实施例中,上行控制信令可以进行本子帧反馈或跨子帧调度反馈。具体的,可参见图6A、图6B与图6C,图6A本发明子帧指示方法中上行控制信令本子帧反馈的示意图,图6B为本发明子帧指示方法中上行控制信令跨子帧反馈的一个示意图,图6C为本发明子帧指示方法中上行控制信令跨子帧反馈的另一个示意图。
当上行控制信令本子帧反馈时,可以对本子帧的下行数据的确认信息,如肯定应答(Acknowledge,ACK)、否定应答(Non-Acknowledge,NACK)进行反馈,以及对信道状态信息(Channel State Information,CSI)、服务请求(Service Request,SR)等进行反馈,其中信道状态信息CSI包括信道质量指示(Channel Quality Indicator,CQI),预编码矩阵指示(Precoding Matrix Index,PMI)和秩指示(Rank Indicator,RI)。图6A所示为第一子帧的上行控制信令对本子帧的下行数据的确认信息进行反馈,或者对信道状态信息或服务请求进行传输。
当上行控制信令跨子帧反馈时,第一子帧的下行控制信令携带第四指示信息,所述第四指示信息指示所述第二设备在第二子帧的上行控制信令中对所述第一子帧的下行数据的确认信息进行反馈或者对信道状态信息或服务请求进行传输。图6B中,最左边两个子帧的下行控制信令分别携带第四指示信息,指示最左边两个子帧的下行数据的确认信息在最右边的子帧的上行控制信令中进行反馈或者对信道状态信息或服务请求进行传输。图6C中,需要在右边子帧中反馈左边子帧的下行数据的ACK/NACK时,需要在左边 子帧的下行控制信令中进行指示,否则第二设备不知道在什么位置反馈ACK/NACK。由于第二设备在接收完左边子帧的下行数据之后,就可以准备相应的ACK/NACK,而不用等到指定的反馈帧再准备。因此,也需要在左边子帧的下行控制信令中指示上行反馈的时域资源或者相应反馈子帧的类型,以及在哪个子帧反馈。
进一步的,当上行控制信令跨子帧反馈时,第一子帧的下行控制信令还携带第五指示信息,所述第五指示信息指示所述第二子帧的上行控制信令占用的时域资源、符号数目和/或符号位置。
基于上述各实施例,下面列举一种可行的减少子帧指示信息开销的方法,具体方式本发明中不做限制:假设一个子帧占用14个符号,下行控制信令和上行控制信令来说,由于下行控制信令需要占用1、2或者3个符号,上行控制信令需要占用1或2个符号。则下行控制信令包含4种可能(0,1,2,3个符号),上行控制包含3种可能(0,1,2)个符号,若需要对下行控制信令和上行控制信令进行指示,则子帧类型共有3×4=12种,需要4比特。由于一个子帧中,下行控制信号的容量(D):上行控制信号的容量(U)在8:1到16:1之间。因此,当一个子帧中同时存在下行控制信令和上行控制信令时,上下行控制信令配比较为合理的可能性是:D:U=1:0、D:U=1:1、D:U=2:0、D:U=2:1、D:U=3:0、D:U=3:1或D:U=3:2,共7种情况,因此,需要3bit即可。举例如下:000→D:U=1:0、001→D:U=1:1、010→D:U=2:0、010→D:U=2:0、011→D:U=2:1、100→D:U=3:0、101→D:U=3:1、110→D:U=3:2、其他(Others)→保留(reserve)。
对于数据部分,即上行数据、下行数据来和间隔说,若第二设备已知下行控制信令和上行控制信令占用的符号数,那么,上行数据和下行数据的具体位置和占用的符号数据依赖于间隔的位置。若间隔的位置确定,则上行数据和下行数据的具体位置和占用的符号数据也确定。假设间隔(Gap)包含2种可能(0,1个符号),除去第一个符号与最后一个符号,间隔可能的位置有12种,因此间隔包含13种可能(包含间隔占用0个符号的情况),需要4比特。结合上述对上下行控制信令的分析可知:若对整个子帧的类型进行指示,则子帧指示信息的大小为3+4=7比特。
进一步的,可以用2比特对间隔的位置进行指示,每种不同的间隔位置对应不同的子帧类型。例如,00:间隔在下行控制信令之后的第一个符号→Type3或者Type4;01:间隔在上行控制信令之前的第一个符号→Type2;10:间隔在上行与下行数据部分中间的→Type7、type8;11:间隔等于0→Type1,Type5或者Type6。结合上述对上下行控制信令的分析可知:若对整个子帧的类型进行指示,则子帧指示信息的大小为3+2=5比特。
基于上述分析可知:需要两个信令或者一个信令的2个不同部分联合指示子帧类型,其中一个指示上行控制信令和下行控制信令,另一个指示间隔的位置和符号数,两个共需要5比特或7比特,从而达到减少子帧指示信息开销的目的。
下面,对上述各实施例中,第一设备如何向第二设备发送子帧指示信息进行详细说明。
在一种可行的实现方式中,第一设备将所述子帧指示信息携带在所述第一子帧的下行控制信令中发送给所述第二设备。该下行控制信令可以是一种共有(common)的下行控制信令,所有第二设备都可以接收并解调译码出相应的信息。
具体的,由于该种方式需要用到第一子帧的下行控制信令,因此第一子帧必须为包含下行控制信令的子帧类型,即Type5和Tpye6类型的子帧不适用该种方式。当第一设备需要向第二设备发送子帧指示信息时,第一设备确定所述第一子帧的下行控制信令的频率位置和符号位置;然后,所述第一设备将所述子帧指示信息携带在所述第一子帧的下行控制信令中,并在所述频率位置和符号位置上发送给所述第二设备。
例如,第一设备根据所述第二设备所处小区的小区标识(identification,ID)和/或系统带宽确定所述频率位置。将小区标识表示为
Figure PCTCN2016101411-appb-000001
则频率位置与
Figure PCTCN2016101411-appb-000002
有关,其中,mod表示求余;a表示比例系数;NRB表示系统带宽。
再如,所述第一设备根据参考信号的位置确定所述频率位置,所述参考信号为所述第二设备所处小区的参考信号(Reference Signal,RS)。具体的,可参见图7,图7为本发明子帧指示信息方法所适用的确定频率 位置的示意图。
请参照图7,点填充部位为参考信号的频率位置,斜方格填充部位为下行控制信令的频率位置,下行控制信令的频率位置位于参考信号的频率位置附近,例如下行控制信令的频率位置和参考信号的频率位置相邻,且下行控制信令占用的符号和参考信号占用的符号相同或相邻。这样可以提升所述子帧指示信息的信道估计性能,从而提升其解调译码性能。
又如,在确定下行控制信令的频率位置的过程中,可同时考虑第二设备所处小区的小区标识、系统带宽与参考信号的位置等。
另外,当通过第一子帧的下行控制信令发送子帧指示信息时,下行控制信令还携带其他信息,如时域信息、调制方式、加扰方式、重复次数等。子帧指示信息在第一子帧的第一个符号中传输,使得第二设备先解调出子帧指示信息,确定子帧类型,从而解调出后面的控制信令和数据;调制方式例如为正交移相键控(Quadrature Phase Shift Keying,QPSK);加扰方式与扰码的初始化因子和小区标识(Cell ID)有关;重复次数可以为N次,即子帧指示信息可以在不同的频域传输N次,从而获得分集接收增益,提高接收性能。
在另一种可行的实现方式中,第一设备将所述子帧指示信息携带在无线资源控制(Radio Resource Control,RRC)信令中发送给所述第二设备。
具体的,第一设备配置或预配置对应关系,所述对应关系指示索引、子帧指示信息与子帧号的对应关系,然后,所述第一设备确定出索引,并将索引携带在所述RRC信令中发送给所述第二设备。当第二设备接收到RRC信令后,可以确定出索引,由于第一子帧的子帧号是已知的,因此,可以根据对应关系确定出子帧指示信息指示的子帧类型。
实现过程中,在一个周期内设计不同的子帧类型图样,例如,一个帧包含10个子帧,每个子帧对应一种子帧类型,用3个或5个比特表示(Value),索引(Index)用2个比特表示,则不同的索引对应不同的子帧类型图样,子帧类型图样又包括不同的Value表示不同的子帧类型,对应不同的子帧指示信息。以子帧类型为5比特为例,当Value=00011时,前面三个比特011表示D:U=1:0,即全部符号被下行控制信令或下行数据占用,是一个全下 行子帧,后面两个比特11表示子帧为间隔等于0的子帧,即可能为Type1,Type5或者Type6。综合可知:Value=00011的子帧为Type1类型的子帧。
上述实施例中,索引可以为半静态调度(Semi-Persistent Scheduling,SPS)的索引等。下面,以子帧类型(Value)为5比特、索引为SPS Index为例,对上述的对应关系进行详细说明,具体的,可参见表1。
根据表1可知:索引为2比特,子帧类型(Value)为5比特,有0~31,即32重不同的组合,不同的值对应不同的子帧指示信息,即对应不同的子帧类型。
表1
Figure PCTCN2016101411-appb-000003
在又一种可行的实现方式中,第一设备将所述子帧指示信息携带在系统广播信息,如主信息块(Master Information Block,MIB)或系统信息块(System Information Block,SIB)中发送给所述第二设备。当子帧类型发送变化时,第一设备将新的子帧类型对应的系统广播信息广播给第二设备,第二设备根据系统广播信息确定子帧类型。具体实现时,也可以采用类似上述通过RRC信令发送的方式,配置索引、子帧指示信息与子帧号的对应关系,并将索引携带在所述系统广播信息发送给第二设备,使得第二设备根据系统广播信息确定子帧类型。
图8为本发明下行控制信令发送方法实施例一的信令图,包括:
201、第一设备确定第一子帧的下行控制信令,所述下行控制信令携带第二指示信息,所述第二指示信息指示所述第二设备发送第二子帧的上行数据。
202、所述第一设备向第二设备发送所述下行控制信令。
相应的,第二设备接收下行控制信令。
203、所述第二设备根据所述第二指示信息发送第二子帧的上行数据。
上述的201~203中,第一子帧的下行控制信令携带第二指示信息,第二指示信息指示第二设备准备第二子帧的上行数据并发送。该种方式下,当第二设备接收到下行控制信令后,根据第二指示信息准备第二子帧的上行数据并发送,实现跨子帧调度上行数据的目的。
