Abstract

本发明公开了一种信息传输方法及装置、计算机存储介质,所述方法包括:根据预设方式或者eNB通知的方式确定传输资源的位置和/或图样,在所述传输资源上传输信息,其中,所述信息包括以下至少之一:下行控制信息、下行数据、上行数据、上行控制信息。

Description

一种信息传输方法及装置、计算机存储介质 技术领域
本发明涉及无线通信领域,尤其涉及一种信息传输方法及装置、计算机存储介质。
背景技术
移动互联网和物联网的快速发展引发了数据流量的爆发式增长和多样化、差异化业务的广泛兴起。5G作为新一代的移动通信技术,相对4G将支持更高速率(Gbps)、巨量链接(1M/Km2)、超低时延(1ms)、更高的可靠性、百倍的能量效率提升等以支撑新的需求变化。其中,超低时延作为5G技术的关键指标,直接影响着如车联网、工业自动化、远程控制、智能电网等时延受限业务的发展。当前一系列关于5G时延降低的标准研究正在逐步推进。
传输时间间隔(TTI,Transmission Time Interval)降低作为当前时延降低的重要研究方向,旨在将现在1ms长度的TTI降低为0.5ms甚至1~2个OFDM符号的长度,成倍地降低了最小调度时间,进而在不改变帧结构情况下也能成倍地降低单次传输时延。目前,第三代合作伙伴计划(3GPP,Third Generation Partnership Project)在RAN1和RAN2工作组已经立项讨论短(short)TTI下的系统设计。
当系统中既有支持short TTI的用户设备或终端(UE,User Equipment)、又有支持1ms TTI的传统(legacy)UE时,如果两者的资源是时分的,会增加支持short TTI的UE的时延。如果两者的资源是频分的,不灵活,还可能有资源浪费。能够缓解上述方式的缺点的一个方法就是支持short TTI的UE和legacy UE在相同的资源上传输,但这种方法对两者的传输都会造 成一定的影响,然而,如何缓解这种方式对两者传输的影响,目前还没有有效的解决方案。

以下通过具体实施例对本申请的技术方案进行说明。
实施例一
本实施例给出多个UE共享相同资源的方法,其中,多个UE的传输资源有部分重叠。
本实施例以支持short TTI的UE和legacy UE在相同资源上传输信息为例来说明。所述方法也可用于两个支持短TTI的UE在相同资源上传输信息,所述方法也可以用于其它类型的UE。本发明实施例对此并不限定。
本实施例以支持Short TTI的UE为例来说明,这里简称S-UE,S-UE传输信息的TTI的长度可以为1、2、3、4、5、6、7个符号,实际应用中不限于S-UE。本实施例中给出一种下行信息的传输方法。为了避免混淆,于此,S-UE的信道前面都加“S-”。本实施例中包括以下之一:S-下行控制信息、S-PDSCH、S-PHICH。
当S-UE传输信息的TTI中包含PDCCH所在的符号时,那么在所述TTI中,S-UE在PDCCH所在的符号之外的符号上进行传输。如图3所示,一个子帧包含7个TTI,每个TTI包含2个符号,图3中的灰色区域为PDCCH 所在的符号,那么TTI#0中的下行信号只在第四个符号以及之后的符号上传输。于此,避开PDCCH传输符号的好处是:避免对PDCCH造成干扰。S-UE的传输对于legacy UE的传输是透明的,S-UE的下行信息在legacy UE的物理下行共享信道(PDSCH,Physical Downlink Shared Channel)的资源上打孔传输,为了使legacy UE能够正确接收,eNB应适当降低legacy UE的码率。
对于常规循环前缀(CP,Cyclic Prefix),一个子帧包含14个符号,一个子帧中的符号按照时间顺序,索引分别为0、1、2、……、13。其中,可用于S-UE传输下行信号的符号索引为k、k+1、……、13,k可以为预设值,比如为2,或者,比如当下行带宽包含的PRB数目时,k=4,当时,k=3或者k由系统中PDCCH占用的符号数确定,比如PDCCH占用的符号数是2,则k=2,即一个子帧中的第3个符号以及之后的符号可用于传输下行信号。S-UE可以通过接收PCFICH,获得PDCCH占用的符号数。
对于扩展CP,一个子帧包含12个符号,一个子帧中的符号按照时间顺序,索引分别为0、1、2、……、11。其中,可用于S-UE传输下行信号的符号索引为k、k+1、……、11,与上述类似,k可以是预设的,或者由PDCCH占用的符号数确定。
实施例二
本实施例中给出一种下行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。所述下行信息包括下行控制信息和/或下行数据。
如果S-UE传输下行信息的TTI中有PDCCH的符号,例如上述图3中的TTI#0和1,如果不允许S-UE的下行信息在包含PDCCH的符号中传输,那么上述的TTI#0对于S-UE就不可用。如此,S-UE就至少得推迟到TTI#1才能传输数据,这样会降低S-UE的传输时延,与S-UE降低时延的要求相 悖。为了解决这个问题,应允许UE在PDCCH的符号中传输,在S-UE的下行信息所在的资源上,对PDCCH进行打孔。如图4所示,PDCCH在前三个符号上传输,在TTI#0上,S-UE的下行信息在PDCCH的区域内打孔传输,即图4的斜线部分。对于legacy UE而言,S-UE的传输是透明的,eNB应适当增大legacy UE的PSCCH的聚合等级以保证legacy UE能正确接收PDCCH。这里以TTI为两个符号为例来说明,实际应用中不限于这种TTI长度,可以为1~7个符号中的任意一个。
PCFICH用于指示PDCCH的传输符号数,在16个RE上传输,如果S-UE的下行信息将PCFICH的资源占用,将PCFICH信息打掉,那么可能会导致UE不能正确接收控制格式指示(CFI,Control Format Indicator)信息,从而对PDCCH区域的判断出错,造成接收PDCCH和PHICH也会相应出错。为了避免这种情况,可选地,S-UE的下行信息应避开PCFICH所在的RE位置,即在PCFICH所在的RE之外的RE上传输。S-UE的下行信息可以映射在PCFICH所在的RE上,然后用PCFICH将S-UE的数据打掉传输,或者也可以在PCFICH所在的RE之外的RE上做速率匹配。
在现有的LTE系统中,PCFICH占用的资源元素组(REG,Resource Element Group)对应的起始RE的索引为、、、,其中,,为一个PRB包含的子载波数,即12,为物理小区标识,为下行系统带宽对应的PRB个数,比如对于20MHz的系统,=100。PCFICH占用的REG为从上述起始RE除去小区专用参考信号(CRS,Cell Specific Reference Signal)位置的接下来的4个RE,不管实际的CRS端口为多少,假设PCFICH所在的符号上的CRS端口为端口0和端口1。
PHICH携带混合自动重传请求(HARQ,Hybrid Automatic Repeat reQuest)确认/否认(ACK/NACK),指示eNB是否正确接收到物理上行共享信道(PUSCH,Physical Uplink Shared Channel)的传输,如果S-UE的 下行信息将PHICH的资源占用,将PHICH信息打掉,那么可能会导致UE不能正确接收HARQ ACK/NACK信息,可能会导致不必要的重传或者导致该重传的数据包没有重传等。为了避免这种情况,可选地,S-UE的下行信息应避开PHICH所在的RE位置,即在PHICH所在的RE之外的RE上传输。在PHICH所在的RE上对S-UE的下行信息进行打孔,或者S-UE的下行信息也可以在PHICH所在的RE之外的RE上做速率匹配。
在本发明一实施方式中,S-UE的下行信息应避开PCFICH以及PHICH所在的RE。
实施例三
本实施例中给出一种下行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。
在本发明一实施方式中,S-UE的下行信息应避开现有的DMRS对应的RE,即在现有DMRS之外的RE上传输。在现有DMRS所在的RE上,对S-UE的下行信息进行打孔,或者S-UE的下行信息也可以在现有DMRS所在的RE之外的RE上做速率匹配。这样,如果eNB给legacy UE发送了DMRS,S-UE的传输不会影响legacy UE的传输。如图5所示,S-UE在灰色区域传输。可选地,S-UE的下行信息映射的资源应避开端口7/8/11/13和9/10/12/14的DMRS对应的RE,或者eNB也可以通知UE避开哪个端口的DMRS,比如用1比特(bit)指示是端口7/8/11/13的DMRS对应的RE,还是端口9/10/12/14的DMRS对应的RE。
在本发明一实施方式中,eNB可以给S-UE指示S-UE的下行信息是否避开现有的DMRS对应的RE。这样,当S-UE和一个基于CRS解调的legacy UE的资源重叠时,eNB可以通知S-UE不用避开现有DMRS对应的RE,这样可以增加S-UE用于传输的资源。当S-UE和一个基于DMRS解调的legacy UE的资源重叠时,eNB可以通知S-UE避开现有DMRS对应的RE, 使得legacy UE的DMRS能够正常发送。可选地,如果eNB给S-UE指示了需要避开现有的DMRS,S-UE的下行信息映射的资源应避开端口7/8/11/13和9/10/12/14的DMRS对应的RE,或者,eNB也可以通知S-UE避开哪个端口的DMRS。比如通过DCI通知或者RRC信令通知。
在本发明一实施方式中,eNB可以给S-UE指示S-UE的下行信息在哪些PRB上需要避开DMRS,或者在哪些PRB上不需要避开DMRS,比如eNB给S-UE采用2bit指示这几种状态:在所有分配的资源上都不需要避开现有DMRS、在频率较低的一半资源上避开现有的DMRS、在频率较高的一半资源上避开现有的DMRS。或者,eNB给S-UE指示需要避开DMRS的PRB对应的资源指示值(RIV,Resource Indication Value),即用下行资源分配类型2来指示,或者也可以用其他资源分配类型来指示。可选地,如果eNB给S-UE指示了需要避开现有的DMRS的PRB,在所述PRB上,S-UE的下行信息映射的资源应避开端口7/8/11/13和9/10/12/14的DMRS对应的RE,或者eNB也可以通知S-UE避开哪个端口的DMRS。
实施例四
本实施例中给出一种上行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。其中,所述上行信息为上行控制信息和/或上行数据。
在小区专有的SRS子帧上,S-UE应避开最后一个符号上的SRS带宽对应的RE,比如SRS带宽为96个PRB,那么最后一个符号上的中心1152(96×12=1152)个RE都不能用于S-UE的传输。
如果S-UE传输信息的TTI中包含legacy DMRS对应的符号,比如对于常规CP,legacy DMRS占用每个时隙的第4个符号,对于扩展CP,legacy DMRS占用每个时隙的第3个符号。在legacy DMRS所在的符号上,S-UE的DMRS也在legacy UE的DMRS上发送。可选地,S-UE的DMRS和legacy  UE的DMRS可以在相同的符号上码分传输。如图6所示,图6中为常规CP下的一个上行子帧,包括14个符号。short TTI占用4个符号,其DMRS在现有DMRS的符号上发送,如图6中short TTI中灰色的符号,S-UE的PUSCH在其他3个符号上发送。
或者,如果S-UE传输信息的TTI中包含legacy DMRS对应的符号,S-UE的上行信号应避开现有的DMRS符号,如图7所示,图7中为常规CP下的一个上行子帧,包括14个符号。S-UE的DMRS为图7中斜线部分的符号,其他两个符号用于发送数据,即网格状的符号。这样,当S-UE和legacy UE占用相同资源的时候,S-UE不会对legacy UE的DMRS造成干扰。S-UE的数据和legacy UE的数据虽然存在一定的干扰,但是eNB可以通过功控或者连续干扰消除(SIC,Successive Interference Cancellation)等方式减轻或者消除两者之间的干扰。
或者,short TTI的划分避开DMRS所在的符号,即short TTI不包括DMRS的符号。如图8所示,图8中为常规CP下的一个上行子帧,包括14个符号。除了DMRS占用的两个符号外,其他符号被划分成了4个TTI,每个TTI包含3个符号,S-UE的DMRS为斜线部分的符号,S-UE的PUSCH为网格部分的符号。
在本发明一实施方式中,在小区专有SRS子帧上,S-UE的PUSCH还应该避开SRS带宽对应的RE。可以按照上述的方式在一个TTI中避开SRS宽对应的RE,或者可以在DMRS、SRS所在的符号之外的符号上定义TTI,即short TTI中不包含DMRS和SRS的符号。
在本发明一实施方式中,S-UE的PUSCH还应该避开legacy PUSCH中的秩指示(RI,Rank Indication)或者ACK/NACK或者信道质量指示(CQI,Channel Quality Indicator)或者预编码矩阵指示(PMI,Precoding Matrix Indicator)所在的RE。eNB可以通过调度避开legacy PUSCH中的上述信息 所在的RE,或者,eNB可以给S-UE通知legacy UE的上述信息所在的位置,S-UE避开所述信息的位置。
实施例五
本实施例中给出一种上行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。其中,所述上行信息为上行控制信息和/或上行数据。
S-UE在SRS对应的资源上发送上行信息。比如,eNB配置了小区专有的SRS子帧和SRS带宽,那么,eNB可以调度S-UE在小区专有的SRS子帧内的SRS带宽内传输。对于FDD,即在SRS子帧的最后一个符号上传输,占用的频域资源可以为整个SRS带宽,或者为SRS带宽的一部分,比如预设的,或者在DCI中指示。
eNB可以通过调度来避免S-UE的信息和其他UE的SRS发生冲突,比如时分,或者频分。对此,本申请不做限制。
在本发明一实施方式中,上述S-UE发送上行信息的传输资源可以一部分是在SRS对应的符号上,另一部分在其他符号上,比如在和SRS相邻的符号上。
实施例六
本实施例中给出一种下行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。
S-UE在CSI-RS对应的资源上接收下行信息,eNB在CSI-RS对应的资源上发送下行信息。比如,eNB给UE配置了CSI-RS,那么eNB可以调度S-UE在CSI-RS对应的资源上传输。S-UE根据eNB的CSI-RS配置来接收下行信息。S-UE传输信息的频域范围可以为整个系统带宽,或者为预设的频域范围,或者为eNB指示的,比如在DCI中指示。图9中给出了常规CP下,CSI配置#0对应的的CSI资源。
采用这样方式,对于不支持CSI-RS的legacy UE,在CSI-RS对应的资源上,eNB对legacy UE的数据进行打孔,为减少影响,应适当降低码率。对于支持CSI-RS的legacy UE,eNB可以将legacy UE的数据绕开CSI-RS做速率匹配,提高性能。
在本发明一实施方式中,上述下行信息的传输资源可以一部分是在CSI-RS对应的资源上,另一部分在其他资源上。
在本发明一实施方式中,所述下行信息可以采用CRS解调,或者也可以采用DMRS解调,如果是后者,所述DMRS可以在所述CSI-RS对应的资源上发送,比如一个PRB中有一个RE用于传输DMRS,实际应用中不限于所述方式。
实施例七
本实施例中给出一种上行/下行信息的传输方法。本实施例以S-UE为例来说明,实际应用中不限于S-UE。
所述S-UE传输信息的传输资源的图样和/或位置为预设的,或者是eNB通知的,比如在SIB或者RRC信令中通知。
在本发明一实施方式中,所述传输资源的图样在频域上为具有指定的间隔的RE,所述间隔为预设的,或者是eNB通知的。比如为每个符号上有离散的等间距的4个RE,如图10中的TTI#3和5所示。或者,可以在DCI或者RRC信令中通知所述传输资源的图样的密度。可选地,eNB可以给S-UE通知所述图样的偏移,比如在图10中,TTI#3的偏移为2,TTI#5的偏移为0。可选地,所述传输资源的图样在频域上可以是在一个PRB或者RBG或者M个PRB中定义,其中,M是一个大于1的整数,所述M是预设的,或者是eNB通知的。比如在一个PRB中是等间隔的,或者也可以是不等间隔的,比如占用一个PRB中的子载波#2、4、9。eNB可以采用相关的资源方式来通知UE,比如分配了PRB#2、3、6、9,那么所述传输资源 在频域上为这几个PRB中的若干个RE,每个PRB中的RE如图10所示。
在本发明一实施方式中,所述指定间隔可以是均匀的,也可以是不均匀的。比如占用一个PRB中的子载波#0、2、10。可选地,所述传输资源的位置可以是预设的,或者eNB配置的,比如所述传输资源在全系统带宽上发送,或者所述传输资源在部分PRB上发送,可以用相关的资源分配类型来指示。
在本发明一实施方式中,所述传输资源可以是一个或者多个连续或者不连续的PRB。比如,假设系统带宽为20MHz,PRB索引分别为0~99,传输资源可以为PRB#0~11,或者为0、2、3、6、9和19。所述传输资源的位置可以是预设的,或者eNB配置的。对于S-UE,所述PRB频域上占用12个子载波,时域上为TTI对应的符号数。
在本发明一实施方式中,所述传输资源可以部分是具有指定的间隔的RE,部分为一个或者多个连续或者不连续的PRB。采用这样的方式,S-UE只在一个子帧中的部分资源上传输,eNB可以只在所述部分资源上对传输其他UE的数据打孔,这样可以降低对其他UE传输的影响。可选地,eNB给所述其他UE通知打掉的部分资源,比如通知所述打掉的部分资源的位置和/或图样,可以在RRC信令或者SIB或者DCI中通知。这样,其他UE可以获知哪些RE上的资源不是自己的,这样,在重传合并时,可以不合并相应位置的数据,减少打孔对性能的影响。
在本发明一实施方式中,所述传输资源的图样和/或位置由小区标识、传输信息的TTI和传输模式确定,如图10所示,斜线部分的资源为S-UE传输信息的RE,对于TTI#3,传输资源的图样和/或位置应避开CRS所在的位置;对于TTI#5,传输资源的图样和/或位置和CRS的位置无关。当传输模式为空频块编码(SFBC,Space-Frequency Block Code)时,频域上的RE数目为2的倍数或者4的倍数。当传输模式为空时块编码(STBC, Space-Time Block Code)时,时域上的RE数目为2的倍数或者4的倍数。
在本发明一实施方式中,一个子帧上的所有TTI上的传输资源的图样和/或位置,都可以根据小区标识确定。
在本发明一实施方式中,所述下行信息可以采用CRS解调,或者也可以采用DMRS解调,如果是后者,所述DMRS可以在所述部分传输资源上发送,比如为TTI中的第一个符号上的所有RE或者部分RE,实际应用中不限于所述方式。
在本发明一实施方式中,所述下行信息的传输模式可以是现有的传输模式,或者是现有传输模式的混合,比如,假设传输资源部分是具有指定的间隔的RE,部分为一个或者多个连续或者不连续的PRB,在离散RE上采用一种传输模式,在一个或者多个不连续的PRB上采用另一种传输模式。或者,也可以定义新的传输模式,比如STBC。
此外,本发明实施例还提供一种信息传输装置,如图11所示,所述装置包括:
