Abstract
一种传输信息的方法,包括:在一个载波上,当两个以上的物理上行共享信道PUSCH的约定传输时间有重叠时,按照预设的发送方式和基站eNB指示的发送方式中至少之一进行传输。
Description
本申请涉及但不限于无线通信领域,尤其涉及一种传输信息的方法及装置、接收信息的方法及装置。
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(5th-Generation,第五代移动通信技术)作为新一代的移动通信技术,相对4G(4th-Generation,第四代移动通信技术)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(Transmission Time Interval,简称TTI)降低作为当前时延降低的重要研究方向,旨在将现在1毫秒(ms)长度的TTI降低为0.5ms,甚至1至2个正交频分多路复用(Orthogonal Frequency Division Multiplexing,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。将这种0.5ms甚至1至2个OFDM符号的长度的TTI称为short TTI(sTTI,短TTI),3GPP(Third Generation Partnership Project,第三代合作伙伴计划)也已立项讨论short TTI时延降低技术。
在短TTI技术中,终端(UE,User Equipment)需要支持短TTI和现有1ms TTI,UE可以在两者之间动态切换。当短TTI的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)和发送1ms TTI的PUSCH在时间上有重叠时,如何进行传输还没有有效的解决方案。

其中,当放弃发送第二PUSCH时,可将第二PUSCH,包括携带的UCI(上行控制信息,Uplink Control Information)全部丢弃,放弃发送,只发送第一PUSCH,在之后的子帧中也不会再发送放弃的第二PUSCH。
当推迟发送第二PUSCH时,将第二PUSCH在该约定传输时间对应的子帧上不发送,推迟到该约到传输时间之后发送,比如,推迟到下个未调度PUSCH的空闲子帧进行传输。这里,当在出现约定传输时间重叠情况的子帧不发送第二PUSCH时,推迟到下个子帧进行传输,当下个子帧也调度了PUSCH时,则继续延迟,直到检测到没有调度PUSCH的子帧时,在该子帧
发送被推迟的第二PUSCH,传输所述第二PUSCH。
在该发送方式中,当所述第二PUSCH的信息中携带上行控制信息(Uplink Control Information,UCI)时,将所述UCI在所述第一PUSCH上发送。这里,在发送第一PUSCH的信息的同时,在发送第一PUSCH的信息的第一PUSCH上发送第二PUSCH的UCI,将第二PUSCH的数据信息放弃发送,从而在保证第一PUSCH的信息发送的同时,将第二PUSCH的UCI也发送;其中,在第一PUSCH上发送的第二PUSCH的UCI的全部信息或部分信息。

这里,预设类型CQI可以为宽带CQI,预设类型PMI可以为宽带PMI。
下面对本实施例提供的一种传输信息的方法中的发送方式一进行进一步说明。
当两种TTI长度的数据的传输时间有重叠时,其中这两种TTI的长度不同。这里,TTI的长度可以是LTE(Long Term Evolution,长期演进)系统中的1ms TTI,或者所述TTI包含2个符号或者4个符号或者7个符号,所述2个符号或者4个符号或者7个符号可以是物理上连续的,或者不连续的。比如TTI长度为2个符号时,DMRS在一个子帧上的第一个符号上发送,上行数据在该子帧的第三个符号上发送。实际应用中,不限定所述TTI的长度。在本实施例中,小于1ms的TTI又称为sTTI(短TTI)。
本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明,本实施例中的方法也可用于两个sTTI同时传输,其中,这两种sTTI的长度不同。比如一个sTTI长度为4个符号,另一个sTTI长度
为2个符号。本实施例中,1ms TTI的PUSCH称为PUSCH,sTTI的PUSCH称为sPUSCH。其中,sPUSCH为第一PUSCH,TTI的长度较短,PUSCH为第二PUSCH,TTI的长度较长。
如图3所示,图3中给出了PUSCH和sPUSCH的传输时间有重叠时的示意图。其中,终端(UE,User Equipment)在子帧n检测到上行授权,UE将要在子帧n+4发送PUSCH,而在子帧n+3内,UE又收到调度UE在子帧n+4的2个符号上发送sPUSCH的上行授权。
此时,可通过以下两种方法来进行sPUSCH和PUSCH的信息的发送。
一种方法是UE传输sPUSCH,放弃传输PUSCH。
在示例性实施方式中,当PUSCH上包含UCI时,所述UCI的所有或者部分信息在sPUSCH上传输。这里,UCI至少包括以下之一:CQI、PMI、HARQ-ACK、RI、CRI,其中,HARQ-ACK为下行数据的反馈信息,比如为1bit的ACK/NACK(确定/否定消息)。所述RI可以是以下之一:只有RI,RI和i1的联合上报,CRI(CSI-RS Resource Indication,CSI-RS(Channel State Information-Reference Signal信道状态信息参考信号)资源指示)和RI的联合上报,CRI、RI和i1的联合上报,CRI、RI和PTI(Precoding Type Indicator,预编码类型指示)的联合上报,RI和PTI的联合上报。其中,i1为Wideband first PMI i1。实际应用中不限于这些信息。
这里,当sPUSCH也包含UCI时,可将PUSCH的UCI和sPUSCH的UCI同时进行传输,其中,可通过级联的方式进行传输。
当将PUSCH上的UCI和sPUSCH上的UCI进行级联传输时,PUSCH上的UCI和sPUSCH上的UCI可按照UCI的类型进行级联传输。比如,sPUSCH上的HARQ-ACK和PUSCH上的HARQ-ACK先级联,然后写入sPUSCH的交织矩阵中,或sPUSCH上的RI和PUSCH上的RI先级联,然后写入sPUSCH的交织矩阵中。这里,级联的顺序可以是预设的,比如sPUSCH的UCI在前,PUSCH的UCI在后。其中,UCI根据类型可分为:HARQ-ACK、RI/CRI、CQI/PMI。
当PUSCH上包含UCI时,所述UCI的部分信息在sPUSCH上传输包括以下至少之一:
如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUSCH上传输,如果所述UCI还包含其他信息,放弃传输所述其他信息;
如果所述UCI包含以下至少之一:HARQ-ACK、RI/CRI,将所述HARQ-ACK和RI/CRI中至少一项放在sPUSCH上传输,如果所述UCI还包含其他信息,放弃传输其他信息;比如,当UCI有HARQ-ACK和RI/CRI以及CQI/PMI,可以将HARQ-ACK和RI/CRI放到sPUSCH上传输,CQI/PMI放弃传输;
如果所述UCI包含HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一时,将所述HARQ-ACK、RI/CRI和预设类型的CQI/PMI中的至少之一放在sPUSCH上传输,放弃传输其他信息。这里预设类型的CQI/PMI可以是某些格式的CQI/PMI,比如为宽带CQI/PMI;例如:当UCI有HARQ-ACK和RI/CRI以及窄带CQI/PMI,可以将HARQ-ACK和RI/CRI放到sPUSCH上传输,将窄带CQI/PMI放弃传输。后面的实施例中,对预设类型的CQI/PMI的描述与这里类似。
另一种当PUSCH和sPUSCH的传输时间有重叠时的传输方法是,将所述PUSCH推迟传输。比如推迟到没有PUSCH和sPUSCH中至少一项要传输的第一个子帧传输,比如在图3中,当子帧n+5没有PUSCH和sPUSCH要传输时,则在子帧n+5传输推迟的PUSCH,如果子帧n+5有PUSCH和sPUSCH中至少一项要传输时,则继续向后推迟,直到推迟到没有PUSCH和sPUSCH中至少一项要传输的子帧为止。在示例性实施方式中,推迟的PUSCH的UCI可以在sPUSCH上传输,类似上述的方式。
在实际应用中,当有超过2个TTI长度的PUSCH的传输时间有重叠时,即超过2个TTI长度的PUSCH中至少有一个符号是相同的,也可以类似采用上述方法。图4给出了3个TTI长度的PUSCH的传输时间有重叠的示意图。其中,3个PUSCH的TTI长度都不同,分别为1ms、4个符号、2个符号。其中,三者重叠的符号是符号#4和#5,斜线部分为DMRS符号。
在这种情况下,为了保证最短的TTI长度的sPUSCH的时延性能,应传输最短的TTI长度的sPUSCH,放弃其他PUSCH和sPUSCH的传输,UCI的处理方式和上述相同。
在实际应用中,本实施例给出的方法不限于用于PUSCH,也可以用于其它信道。
下面对本实施例提供的传输信息的方法中的发送方式二进行进一步说明。
与图1对应的实施例类似,本实施例给出当两种TTI长度的数据的传输时间有重叠时的传输方法,其中,以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,为第三PUSCH,sTTI的PUSCH称为sPUSCH,为第一PUSCH。
在本实施例中,调度sPUSCH的上行授权中的资源分配必须和调度PUSCH的上行授权中的资源分配相同。
sPUSCH在PUSCH上打孔传输,这里打孔传输是指在离散傅里叶变换(Discrete Fourier Transform,DFT)操作之前,sPUSCH上的信息在PUSCH的交织矩阵上打孔传输,或者,也可以叫做sPUSCH上的信息在交织矩阵中覆盖所述PUSCH上的部分信息。
例如,PUSCH对应的传输时间为子帧n,sPUSCH对应的传输时间为子帧n上的前两个符号,那么,在PUSCH的交织矩阵中,前两个符号对应的列被sPUSCH上的信息覆盖。比如,PUSCH的交织矩阵为(Rmux×Cmux),Rmux为行数,Cmux为列数。如下所示,矩阵中的每个元素y
i(i为整数,且0≤i≤(R′mux×Cmux-1))为1列(Qm·NL)行的向量。R′mux=Rmux/(Qm·NL),其中,Qm为调制阶数,NL为层数。为PUSCH传输的符号数,不包含发送DMRS的符号,如果有信道探测参考信号(Sounding Reference Signal,SRS),也不包含发送SRS的符号。
由于sPUSCH占用前两个符号,那么sPUSCH将交织矩阵中前两个符号对应的列上的PUSCH的信息覆盖,即覆盖前两列。如图5所示,前两列为sPUSCH的信息,其余的列为PUSCH本身的信息。在示例性实施方式中,sPUSCH写入的方式可以是预设的,比如从第一行向下,先列后行的方式写
入;或者,可以从第一列向右,先行后列的方式写入。
这里,当sPUSCH的对应的符号包含PUSCH的DMRS所在的符号时,在所述符号上,仍然发送PUSCH的DMRS,不覆盖PUSCH的DMRS。
在本实施例中,调度sPUSCH的上行授权和调度PUSCH的上行授权中的传输块数目可相同。其中,调度sPUSCH上行授权和调度PUSCH的上行授权中的每个传输块包含的层数相同。
在本实施例中,调度sPUSCH的上行授权中和调度PUSCH的上行授权中的传输块数目可不同,但两者有一个传输块对应的层数相同。比如,sPUSCH包含一个传输块,该传输块对应2层,PUSCH包含两个传输块,一个传输块对应2层,一个传输块对应1层。
在本实施例中,调度sPUSCH的上行授权和调度PUSCH的上行授权中的MCS可相同。比如,两者都有两个传输块,两个传输块的MCS分别相同;或者,sPUSCH有一个传输块,PUSCH有两个传输块,sPUSCH和PUSCH中的一个传输块的MCS相同。
在本实施例中,当PUSCH包含2个传输块,sPUSCH包含1个传输块时,sPUSCH的传输块在PUSCH上的两个传输块上重复传输。当PUSCH包含2个传输块,sPUSCH包含1个传输块时,sPUSCH的传输块在PUSCH上的1个传输块上传输;示例性地,sPUSCH在MCS最高的传输块上发送,或者sPUSCH在预设的传输块上发送,比如sPUSCH的传输块在PUSCH的第1个传输块上发送。当PUSCH包含2个传输块,sPUSCH包含2个传输块时,sPUSCH的两个传输块分别在PUSCH上的2个传输块上传输。当PUSCH包含1个传输块,sPUSCH包含2个传输块时,sPUSCH的2个传输块均在PUSCH上的1个传输块上传输。
示例性地,当在PUSCH的1个传输块中发送时,可以在该传输块对应的所有层上发送,或者在部分层上发送。比如,sPUSCH发送的层数由调度sPUSCH的DCI确定,比如PUSCH的一个传输块对应4层,调度sPUSCH的DCI中通知sPUSCH的一个传输块对应2层,则sPUSCH只传输2层。又比如,当PUSCH的传输块的层数大于1,sPUSCH的传输块的层数等于1时,所述sPUSCH在PUSCH的传输块上的所有层上重复传输。
这里,当PUSCH上有UCI时,其中,UCI包括HARQ-ARQ、RI/CRI和CQI/PMI中的至少之一,sPUSCH的信息不覆盖PUSCH的UCI的部分或者所有信息,即在UCI的部分或者所有信息之外对PUSCH的信息进行覆盖。
示例性地,如果所述UCI包含HARQ-ACK,sPUSCH的信息写入交织矩阵时应跳过所述HARQ-ACK,如果所述UCI还包含其他信息,则可以覆盖。
示例性地,如果所述UCI包含以下至少之一:HARQ-ACK、RI/CRI,sPUSCH的信息写入交织矩阵时应跳过HARQ-ACK和RI/CRI中至少之一,如果所述UCI还包含其他信息,则可以覆盖。
示例地,如果所述UCI包含HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一时,sPUSCH的信息写入交织矩阵时应跳过HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一,放在sPUSCH上传输,如果所述UCI还包含其他信息,则可以覆盖。
需要说明的是,即使UCI信息中不包含HARQ-ACK,sPUSCH也不在交织矩阵中HARQ-ACK对应的位置上覆盖,而是让开HARQ-ACK的位置,以免当UE漏检PDCCH时,使得eNB对sPUSCH在交织矩阵中的位置产生混淆。
或者,当PUSCH的信息中包含第一UCI,且sPUSCH对应的符号和PUSCH的信息中的UCI所在的符号有重叠时,在将sPUSCH的信息写入交织矩阵时,跳过PUSCH的信息中UCI的部分信息或者全部信息对应的位置。这里第一UCI为RI/CRI和CQI/PMI中的至少之一。比如,只跳过RI/CRI对应的位置。
当PUSCH的信息中包含HARQ-ACK,并且sPUSCH对应的符号和PUSCH的信息中的HARQ-ACK所在的符号有重叠时,先将PUSCH的信息写入,然后再写入HARQ-ACK。
例如,当PUSCH中包含RI和HARQ-ARQ时,sPUSCH写入的符号中也恰好包含了RI和HARQ-ARQ所在的符号,那么在sPUSCH对应的符号上,可以采用下面的顺序写入,先写入RI和PUSCH的信息,然后,按照预设的方式写入sPUSCH的信息,比如从第一行开始向下写入,最后,将HARQ-ARQ
在对应的位置上打孔写入,即覆盖交织矩阵中原本写入的信息。
示例性地,当PUSCH上有UCI时,当sPUSCH对应的符号和UCI对应的符号有重叠时,则sPUSCH向后推迟到不和PUSCH的UCI冲突的位置上,比如推迟到下一个sTTI。
当sPUSCH对应的符号和PUSCH的DMRS对应的符号没有重叠时,在该子帧上,只发送PUSCH对应的DMRS,当sPUSCH对应的符号和PUSCH的DMRS对应的符号有重叠时,在PUSCH的DMRS对应的符号上,仍然发送PUSCH的DMRS。sPUSCH只在所述DMRS所在符号之外的其他的sPUSCH对应的符号上发送。
当有超过2个TTI长度的PUSCH的传输时间有重叠时,也可以类似采用上述方法。为了保证较短的TTI长度的sPUSCH的时延性能,将TTI长度最短的的两个PUSCH按照上述方式进行处理。比如图4中将2符号sPUSCH和4符号sPUSCH按照本实施中的方法进行处理。
下面对本实施例提供的传输信息的方法中的发送方式三进行进一步说明。
与图1所示的实施例类似,本实施例给出当两种TTI长度的数据的传输时间有重叠时的传输方法,其中,本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,为第三PUSCH,sTTI的PUSCH称为sPUSCH,为第一PUSCH。
在本实施例中,在sPUSCH对应的符号上,只传输sPUSCH的信息,不传输PUSCH的信息,在PUSCH对应的其余符号上仍传输PUSCH的信息。如图6所示,图中PUSCH为一个子帧中的14个符号,其中sPUSCH占用符号#6、7,斜线部分为DMRS。在该方法中,sPUSCH和PUSCH对应的频域资源可以是重叠、或者不重叠或者部分重叠的。
为了避免对PUSCH对应的DMRS和UCI中至少一项产生影响,可以规定不允许sPUSCH在所述UCI的部分或者所有信息对应的符号上传输,也就是说,UE不期望接收到这样的上行授权,所述上行授权调度UE在包含UCI和DMRS中至少一项的符号上传输sPUSCH。这里,所述UCI的部分或者所有信息对应的符号包括以下至少之一:不管PUSCH上是否有HARQ-ACK,
PUSCH对应的HARQ-ACK对应的符号,避免因为UE漏检控制信道造成没有发送HARQ-ACK时造成eNB和UE的理解不同;如果PUSCH包含RI/CRI,RI/CRI对应的符号;如果PUSCH中包含CQI/PMI,CQI/PMI对应的符号。
或者,当PUSCH上有UCI时,可以采用下述的方法之一进行发送:
方式一:
不管sPUSCH位置如何,当PUSCH上有UCI时,所述UCI的全部或者部分信息都放到sPUSCH上传输。
对于UCI的全部或者部分信息都放到sPUSCH上传输,包括:
如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUSCH上传输,如果所述UCI还包含其他信息,放弃传输所述其他信息。
如果所述UCI包含以下至少之一:HARQ-ACK、RI/CRI,将所述HARQ-ACK和RI/CRI中至少之一放在sPUSCH上传输,如果所述UCI还包含其他信息,放弃传输其他信息。
如果所述UCI包含HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一时,将所述HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一放在sPUSCH上传输,放弃传输其他信息。
后面提到的所述UCI的全部或者部分信息放到sPUSCH上传输的描述与这里类似。
方式二:
当PUSCH上有UCI,且sPUSCH对应的符号和UCI对应的符号有重叠时,将重叠部分的UCI的全部或者部分信息放到sPUSCH上传输。这里,符号有重叠是指有部分符号相同。比如,HARQ-ACK和CSI(Channel State Information,信道状态信息)中至少一项重叠,则将HARQ-ACK和CSI中至少一项放到sPUSCH上。当UCI不重叠时,则UCI仍放置在PUSCH上。如图7所示,当sPUSCH对应前两个符号时,如果PUSCH上刚好有RI发送,那么将RI放到PUSCH上传输。所述重叠部分的UCI的全部或者部分信息的描述与方式一类似。
方式三:
当sPUSCH对应的符号和所述UCI的全部或者部分信息对应的符号有重叠时,sPUSCH仍然在所述重叠的符号上传输。
方式四:
当sPUSCH对应的符号和所述UCI的全部或者部分信息对应的符号有重叠时,则sPUSCH向后推迟到不和UCI冲突的位置上。比如推迟到下一个没有UCI信息的sTTI。
当sPUSCH对应的符号和PUSCH的DMRS所在符号有重叠时,可以采用下述的方式之一进行传输:
方式一:
sPUSCH在DMRS所在的符号上传输,可以采用剩下的其他符号上的DMRS对PUSCH进行解调,比如sPUSCH在第一个时隙上,可以采用第二个时隙上的DMRS对PUSCH进行解调。
方式二:
按照sPUSCH和PUSCH频域跨度生成一个DMRS。如图8所示,sPUSCH对应的符号是符号#2和3,和PUSCH的第一个时隙的DMRS符号有重叠,此时,按照PUSCH和sPUSCH的频域跨度生成一个DMRS,即从两者的最低频率到最高频率生成一个DMRS。DMRS的时域位置可以是PUSCH的DMRS所在符号,也可以是sPUSCH的DMRS所在符号,图8中DMRS的时域位置是DMRS所在符号。
当有超过2个TTI长度的PUSCH的传输时间有重叠时,也可以类似采用上述方法。为了保证较短的TTI长度的sPUSCH的时延性能,将TTI长度最短的两个PUSCH按照上述方式进行处理。对于其他的PUSCH,采用放弃或推迟方式,这里,具体的放弃或推迟的细节参见发送方式一的实施例的描述。当其他的PUSCH包括UCI时,可将这些UCI的部分信息或全部信息在sPUSCH上发送。比如图3中将2符号sPUSCH和4符号sPUSCH按照本实施例中的方法进行处理。
这里,当有超过2个TTI长度的PUSCH的传输时间有重叠时,在一个传输符号上,只传输指定PUSCH,其中,所述指定PUSCH满足以下条件之
一:在所述两个以上的PUSCH中,只有指定PUSCH的约定传输时间包括所述传输符号;在所述两个以上的PUSCH中,有多个PUSCH的约定传输时间包括所述传输符号,在所述多个PUSCH中,指定PUSCH对应的TTI长度最小。
如图9所示,三种TTI长度的PUSCH的约定传输时间有重叠,分别是1ms的PUSCH,4符号的sPUSCH和2符号的sPUSCH,其中,1ms的PUSCH的约定传输时间是符号0至13,4符号的sPUSCH的PUSCH的约定传输时间是符号5至8,2符号的sPUSCH的约定传输时间是符号7和8。那么,在符号7和符号8上,2符号的sPUSCH的TTI长度最小,只传输2符号的sPUSCH,在符号#5和6上,4符号的sPUSCH的TTI长度最小只传输4符号的sPUSCH,在其余的符号上,即符号#0至4以及9至13,只有1ms的PUSCH的约定传输时间包括该符号,只传输1ms的PUSCH。
当第二PUSCH的信息中携带UCI时,将所述UCI的部分或者全部信息在所述第一PUSCH上发送。其中,第一PUSCH为约定传输时间重叠的PUSCH中TTI长度最小的PUSCH,第二PUSCH为约定传输时间重叠的PUSCH中除第一PUSCH以外的PUSCH。同上面的例子,4符号的sPUSCH和1ms的PUSCH为第二PUSCH,2符号的sPUSCH为第一PUSCH,当4符号的sPUSCH和1ms的PUSCH携带UCI时,将携带的UCI的部分信息或者全部信息在2符号的PUSCH上发送。
下面对本实施例提供的传输信息方法中的发送方式四进行进一步说明。
与图1所示实施例类似,本实施例给出当两种TTI长度的数据的传输时间有重叠时的传输方法,其中,本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,为第三PUSCH,sTTI的PUSCH称为sPUSCH,为第一PUSCH。
在本实施例中,当sPUSCH和PUSCH对应的频域位置没有重叠时,将sPUSCH和PUSCH同时发送,则将sPUSCH的信息和PUSCH的信息同时发送。
当sPUSCH和PUSCH的DMRS有重叠时,可以按照sPUSCH和PUSCH
对应的频域总资源生成DMRS序列,然后分别映射到一个符号中sPUSCH和PUSCH对应的总频域资源上。比如PUSCH对应物理资源块(Physical Resource Block,PRB)#1至6,共6个PRB,sPUSCH对应PRB#11至20,共10个PRB,那么DMRS序列在16个PRB上产生,然后分别映射到PRB#1至6、11至20上。DMRS所在的符号可以是预设的和eNB指示的中至少之一,比如为sPUSCH的DMRS所在的符号,或者为PUSCH的DMRS所在的符号,或者为sPUSCH的第一个符号。DMRS对应的循环移位可以是预设的和eNB指示的中至少之一,比如为sPUSCH对应的DCI指示的,或者为PUSCH对应的DCI指示的。
或者,当sPUSCH和PUSCH的DMRS有重叠时,PUSCH和sPUSCH的DMRS分别在各自的频域范围内发送。
在本实施例中,在sPUSCH所在的符号上,sPUSCH和PUSCH的数据可以通过一个DFT产生,DFT的大小由sPUSCH和PUSCH的总频域资源确定,比如sPUSCH占2个PRB,PUSCH占3个PRB,那么DFT大小为(2+3)×12=60,DFT后的值映射到sPUSCH和PUSCH对应的子载波上,然后做IFFT(Inverse Fast Fourier Transform,快速傅里叶逆变换)。或者,sPUSCH和PUSCH分别采用一个DFT产生,如上例,sPUSCH的DFT大小为2×12=24,PUSCH的DFT大小为3×12=36。sPUSCH的DFT产生的信号映射在sPUSCH对应的子载波上,PUSCH的DFT产生的信号映射在PUSCH对应的子载波上。
当有超过2种TTI长度的PUSCH的约定传输时间有重叠时,且所有PUSCH的频域资源都不重叠时,也可以采用上述的方法进行传输,DMRS的产生方式是类似的。
下面对本实施例提供的传输信息的方法中的发送方式五进行进一步说明。
与图1所示的实施例类似,本实施例给出当两种TTI长度的数据的约定传输时间有重叠时的传输方法,本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,为第三PUSCH,sTTI的PUSCH称为sPUSCH,为第一PUSCH。本实施例中的方法也用于两种以上的TTI长度的数据的传输时
间有重叠时。
根据sPUSCH和PUSCH携带的UCI的情况来来确定传输优先级。这里,在确定优先级时,可采用如下方式中的至少一种:
携带有UCI的sPUSCH/PUSCH的优先级高于没有携带UCI的sPUSCH/PUSCH的优先级;即当sPUSCH携带UCI,而PUSCH未携带UCI时,则传输sPUSCH,放弃PUSCH传输;如果PUSCH携带UCI时,而sPUSCH未携带UCI时,则传输PUSCH,则放弃sPUSCH的传输。
携带HARQ-ACK的sPUSCH/PUSCH的优先级高于携带RI/CRI和CQI/PMI中至少之一的sPUSCH/PUSCH的优先级;即当sPUSCH携带HARQ-ACK,而PUSCH未携带HARQ-ACK时,则传输sPUSCH,放弃PUSCH传输。
携带宽带CQI/PMI的PUSCH的优先级比携带窄带CQI/PMI的PUSCH优先级高。
当sPUSCH/PUSCH携带的UCI类型相同的情况下,sPUSCH的优先级高于PUSCH的优先级。即优先传输sPUSCH,放弃传输PUSCH。
当sPUSCH和PUCCH都携带HARQ-ACK时,PUSCH携带的HARQ-ACK与sPUSCH上携带的HARQ-ACK级联后在sPUSCH上发送。
需要说明的,本实施例中的设置优先级高低并根据优先级的高低来进行PUSCH的信息发送的方法,也可以用于PUSCH的TTI长度相同时的情况。
当有超过2种TTI长度的PUSCH的传输时间有重叠时,也可以类似采用上述方法来确定优先级。
在本申请提供的传输信息的方法的一种示例性实施例中,当两种TTI长度的数据的约定传输时间有重叠时的传输方法,本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,sTTI的PUSCH称为sPUSCH,其中sPUSCH为第一PUSCH。本实施例中的方法也用于两种以上的TTI长度的数据的传输时间有重叠时。
在本实施例中,根据两个以上的PUSCH中的第一PUSCH对应的TTI长度确定发送方式,其中,根据sPUSCH的时域符号数确定采用的不同的传输方法。比如,当sPUSCH的时域符号数为7个时,根据上述实施例中的发送方式五的方法进行传输。当sPUSCH的时域符号数小于7个时,采用上述实施例中的发送方式二的方法进行传输。在实际应用中,不限于上述举例。可以根据所述两个以上的PUSCH的TTI的长度的数据来确定对应的发送方式,也可确定一个长度范围对应一种发送方式,当确定第一PUSCH的TTI的长度所述的范围时,则确定该PUSCH对应的发送方式。比如,当1ms和2符号的PUSCH约定传输时间重叠时对应一种传输方式,2符号和4符号的PUSCH的约定传输时间重叠时对应另一种传输方式。
在本申请提供的传输信息的方法的一种示例性实施例中,与图1所示的实施例类似,本实施例给出当两种TTI长度的数据的传输时间有重叠时的传输方法,本实施例以1ms TTI的PUSCH和sTTI的PUSCH的传输时间有重叠时的场景为例来说明。本实施例中,1ms TTI的PUSCH称为PUSCH,sTTI的PUSCH称为sPUSCH。本实施例中的方法也用于两种以上的TTI长度的数据的传输时间有重叠时。
当PUSCH和sPUSCH的频域资源有重叠时,在sPUSCH所在的符号上,将PUSCH的交织矩阵中的sPUSCH所在的符号对应的列取出生成一个交织矩阵P1,为R1行L列。根据sPUSCH分配的资源,生成sPUSCH的交织矩阵P2为R2行L列。UE根据PUSCH和sPUSCH对应的总的频域资源,产生一个更大的交织矩阵P,R行L列,其中R>R1、R2,将P1从P的第一行开始写入,即P1写入了P的前R1行。然后,将P2从P的最后一行写入,即写入P的最后R2行,当遇到PUSCH的信息时,覆盖掉PUSCH的信息。将交织矩阵按列读出,进行后续的DFT和IFFT处理。示例性地,在sPUSCH所在的符号上,如果有PUSCH的DMRS,则在所述DMRS所在的位置上生成一个新的DMRS,该新的DMRS占用的频域资源为PUSCH和sPUSCH对应的总的频域资源。
图10为本申请实施例提供的一种传输信息的装置的示意图。本实施例提供一种传输信息的装置,应用于发送端,如图10所示,所述装置包括:发送单元1001,配置为在一个载波上,当两个以上的PUSCH的约定传输时间有重叠时,按照预设的发送方式和eNB指示的发送方式中至少之一进行传输。
