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。第五代移动通信技术(5G)作为新一代的移动通信技术,相对第四代移动通信技术(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。

降低TTI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个正交频分复用(OFDM)符号的长度,这样就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)也已立项讨论短(short)TTI(sTTI)时延降低技术。
当采用降低TTI的方式来降低时延后,发送不同的信道时各信道对应的TTI长度可能不同,就会出现不同TTI长度的信道在发送时间上有重叠的情况,这种情况下如何进行信道发送目前还没有解决方案。具体来说,在短TTI技术中,用户设备(UE)需要支持sTTI和现有1ms长度的TTI,UE可以在两者之间动态切换。当短TTI的信道和1ms TTI的信道在发送时间上有重叠时,如何进行信道发送还没有有效的解决方案,是目前亟待解决的问题。
基于此,在本发明的各种实施例中:当至少两个上行信道的约定传输时间有重叠时,发送设备确定发送方式,按照所述发送方式发送目标信号;所述发送方式是预设的和/或基站指示的;所述至少两个上行信道中至少有两个上行信道对应的TTI长度不同;所述上行信道为数据信道或者控制信道,在所述至少两个上行信道中至少有一个控制信道。

下面以控制信道为物理上行链路控制信道(PUCCH,Physical Uplink Control CHannel),数据信道为物理上行共享信道(PUSCH,Physical Uplink Shared CHannel为例,并在实施例一的基础上,在实施例二至十二中详细描述信道发送的过程。
需要说明的是:在实施例二至十二中,sTTI的PUCCH又可以成为
sPUCCH,sTTI的PUSCH又可以称为sPUSCH。
实施例二
本实施例给出在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应的TTI长度不同。这里,TTI的长度可以是现有长期演进(LTE)系统中的1ms TTI,或者所述TTI包含2个传输符号、4个传输符号、或者7个传输符号等。其中,2个传输符号、4个传输符号、或者7个传输符号可以是物理上连续的,也可以是不连续的。比如TTI长度为2个传输符号时,PUSCH的DMRS在一个子帧上的第一个传输符号上发送,上行数据在该子帧的第三个传输符号上发送。实际应用中TTI的长度不限于本实施例中描述的TTI长度。在本实施例中,长度小于1ms的TTI称为sTTI。在本实施例中,PUSCH的TTI长度大于PUCCH的TTI长度。比如PUSCH的TTI长度为1ms,PUCCH的TTI长度为4个传输符号;或者,PUSCH的TTI长度为4个传输符号,PUCCH的TTI长度为2个传输符号。本实施例以1ms TTI的PUSCH和sTTI的PUCCH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以用于其它TTI长度的应用场景。图2给出了PUSCH和sPUCCH的传输时间有重叠时的示意图。其中,UE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sPDSCH,需要在n+4子帧发送sPUCCH。
对于这种情况,可以有以下几种实现方式:
第一种方式,sPUCCH和PUSCH同时传输,即在sPUCCH所在的传输符号上,UE同时发送2个信道。
其中,所述sPUCCH和PUSCH对应的频域资源不重叠。该方式也可以用于两个以上的信道的约定传输时间有重叠时,可以同时发送所述两个以上的信道。
第二种方式,如果sPUCCH包含CSI,则所述CSI在PUSCH上发送,比如写入PUSCH的交织矩阵中,写入的位置可以是sPUCCH对应的传输符号位置。如果sPUCCH上除了CSI外还有其他信息,则将所述其他信息
放在sPUCCH上传输。如果没有其他信息,则不发送sPUCCH,只发送PUSCH。
这里,实际应用时,如果sPUCCH上有周期CSI,PUSCH上有非周期CSI,则sPUCCH上的CSI放弃传输。如果sPUCCH上除了CSI还有其他信息,则将所述其他信息放在sPUCCH上传输。如果没有其他信息,则不发送sPUCCH信道,只发送PUSCH。
实施例三
与实施例一类似,本实施例给出在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应的TTI长度不同。
在本实施例中,PUSCH的TTI长度大于PUCCH的TTI长度。本实施例以1ms TTI的PUSCH和sTTI的PUCCH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以用于其它TTI长度。
对于这种情况,可以有以下几种实现方式:
第一种方式,UE传输sPUCCH,放弃传输PUSCH。
可选地,当PUSCH包含UCI时,所述UCI的所有或者部分信息在sPUCCH上传输。这里,UCI包括以下至少之一:CQI和/或PMI(本发明中用CQI/PMI表示)、HARQ-ACK、RI和CRI,其中HARQ-ACK为下行数据的反馈信息,比如为1bit的ACK/NACK。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。实际应中不限于这些信息。可选地,如果所述UCI包含HARQ-ACK,则将所述HARQ-ACK放在sPUCCH上传输,如果所述UCI还包含其他信息,则放弃传输其他信息。
可选地,如果所述UCI包含HARQ-ACK和/或RI/CRI,则将所述HARQ-ACK和/或RI放在sPUCCH上传输,如果所述UCI还包含其他信息,
则放弃传输其他信息。比如,当UCI有HARQ-ACK和RI/CRI以及CQI/PMI,可以将HARQ-ACK和RI/CRI放到sPUCCH上传输,将CQI/PMI放弃传输。
可选地,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,将所述HARQ-ACK、RI/CRI和预设类型的CQI/PMI中的至少之一放在sPUCCH上传输,放弃传输其他信息。
其中,预设类型CQI/PMI可以是某些格式的CQI/PMI,比如为宽带CQI/PMI等。举个例子来说,当UCI包含HARQ-ACK和RI/CRI以及窄带CQI/PMI,可以将HARQ-ACK和RI/CRI放到sPUCCH上传输,窄带CQI/PMI放弃传输。
进行传输处理时,如果所述UCI的bit数与所述sPUCCH上的bit数之和超过了sPUCCH所能支持的bit数时,可以采用HARQ-ACK bundling技术。
PUSCH的UCI中被放弃传输的信息可以在下一个调度的PUSCH上传输。
第二种方式,UE传输sPUCCH,并将PUSCH推迟传输。
举个例子来说,将PUSCH推迟到没有PUSCH要传输的第一个子帧传输,比如在图2中,当子帧n+5没有PUSCH和sPUCCH要传输时,则在子帧n+5传输需要推迟的PUSCH,如果子帧n+5有PUSCH和/或sPUCCH要传输时,则继续向后推迟,直到推迟到没有PUSCH要传输的子帧为止。实际应用时,当有超过两个上行信道的传输时间有重叠,且其中有一个是PUCCH,且该PUCCH的TTI长度最短,也可以类似采用上述方法。为了保证较短TTI长度的PUSCH的时延性能,将PUSCH中TTI长度最短的PUSCH和该PUCCH按照上述方式进行处理。可选地,其余PUSCH可以放弃传输或者推迟传输。比如图3中将具有2个传输符号的sPUCCH和具有4个传输符号的sPUSCH按照本实施中的方法进行处理。
当有一个PUCCH、多个PUSCH的传输时间有重叠时,其中PUCCH对应的TTI长度最小,如图3所示,此时,只传输所述PUCCH,放弃传输其他信道。可选地,将多个PUSCH上的UCI放到PUCCH上传输,或者只把指定类型的UCI放到PUCCH上传输。类似前面的描述,比如指定类型
的UCI为HARQ-ACK,或者为HARQ-ACK和RI/CRI的至少之一,或者为HARQ-ACK、RI/CRI和预设类型CQI/PMI的至少之一。比如,只把HARQ-ARQ放到sPUCCH上传输。实际应用中不限于这种方式,比如也可以只把HARQ-ARQ和RI中的至少之一放到sPUCCH上传输。
当有多个PUCCH、一个或者多个PUSCH的传输时间有重叠时,其中TTI长度最小的是其中一个PUCCH。那么传输所述TTI长度最小的PUCCH,其他PUCCH上的UCI或者指定类型的UCI在所述TTI长度最小的PUCCH上传输。放弃传输其他信道或者推迟传输其他信道。可选地,当PUSCH上有UCI时,将所述UCI或者指定类型的UCI在所述TTI长度最小的PUCCH上传输。这里,PUCCH上的UCI包括CSI、SR和HARQ-ACK的至少之一。指定类型的UCI可以为HARQ-ACK、或者SR、或者SR和HARQ-ACK、或者预设类型的CSI、SR和HARQ-ACK的至少之一。这里预设类型的CSI可以是宽带CSI或者其他,该定义也用于后面的实施例。比如,有2-符号的PUCCH,4-符号的PUSCH,7-符号的PUCCH,1ms的PUSCH,那么,只发送2-符号的PUCCH。其他PUCCH和PUSCH上的UCI可以放在2-符号的PUCCH上发送。
当有多个PUCCH、一个或者多个PUSCH的传输时间有重叠时,其中,TTI长度最小的是PUSCH,那么,只传输所述多个PUCCH中TTI长度最小的一个PUCCH,其他PUCCH上的UCI或者指定类型的UCI在所述TTI长度最小的PUCCH上传输。放弃传输其余信道或者推迟传输其余信道。可选地,当PUSCH上有UCI时,将所述UCI或者指定类型的UCI在所述TTI长度最小的PUCCH上传输。比如,有2-符号的PUSCH,4-符号的PUCCH,7-符号的PUCCH,1ms的PUSCH,那么,只发送4-符号的PUCCH。其他PUCCH和PUSCH上的UCI可以放在2-符号的PUCCH上发送。
实施例四
与实施例一类似,本实施例中,在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应的TTI长度不同。
在本实施例中,PUSCH的TTI长度大于PUCCH的TTI长度。本实施例以1ms TTI的PUSCH和sTTI的PUCCH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以用于其它TTI长度。
对于这种情况,在本实施例中,只发送PUSCH。具体地,在离散傅里叶变换(DFT)操作之前,sPUCCH上的UCI在PUSCH的交织矩阵上打孔传输。这里,也可以称为sPUCCH上的UCI在交织矩阵中覆盖PUSCH上的部分信息。
下面给出一个例子。PUSCH对应的传输时间为子帧n,sPUCCH对应的传输时间为子帧n上的前两个传输符号,那么,在PUSCH的交织矩阵中,前两个传输符号对应的列被sPUCCH上的UCI覆盖。
可选地,sPUCCH上的UCI可以占满sPUCCH对应的传输符号对应的交织矩阵上的数据。比如,PUSCH的交织矩阵为(Rmux×Cmux)的矩阵,Rmux为行数,Cmux为列数,如图4所示。在图4中,交织矩阵中的每个元素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SRS,也不包含发送SRS的符号。
由于sPUCCH占用交织矩阵中前两个传输符号,那么sPUCCH将会覆盖交织矩阵中前两个符号对应的列上的PUSCH的信息,即覆盖前两列。如图5所示。
可选地,当sPUCCH对应的传输符号包含PUSCH的DMRS所在的传输符号时,在PUSCH的DMRS所在的传输符号上,仍然发送PUSCH的DMRS。
更具体来说,当sPUCCH对应的传输符号和PUSCH的DMRS对应的传输符号没有重叠时,在该子帧上,只发送PUSCH对应的DMRS;当sPUCCH对应的传输符号和PUSCH的DMRS对应的传输符号有重叠时,在PUSCH的DMRS对应的传输符号上,仍然发送PUSCH的DMRS。sPUCCH只在所述DMRS所在传输符号之外其他的sPUCCH对应的符号上发送。
可选地,sPUCCH上的UCI占用的资源数是eNB配置的,比如计算
sPUCCH占用的资源数的公式中的参数是eNB配置的。
可选地,sPUCCH上的UCI写入PUSCH的交织矩阵时,按照预设的方式写入,比如从上到下逐行写入,或者从下到上逐行写入等。
可选地,sPUCCH上的UCI可以在PUSCH的所有传输块上发送,或者也可以在PUSCH的2个传输块中的一个传输块上发送。在一实施例中,sPUCCH上的UCI在MCS索引值较大的传输块上发送,当两个传输块的MCS索引值相同时,可以在预设的传输块上发送,比如在第一个传输块上发送等。
可选地,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。比如在PUSCH的传输块上的所有层上重复传输。
可选地,当PUSCH上包含UCI时,sPUCCH中的UCI信息写入时应跳过PUSCH上的UCI对应的信息。
可选地,当PUSCH上有RI/CRI和CQI/PMI中的至少之一时,sPUCCH的UCI不能覆盖所述RI/CRI和CQI/PMI中的至少之一的部分或者所有信息,即在RI/CRI和CQI/PMI中的至少之一的部分或者所有信息之外对PUSCH的信息进行覆盖,即在RI/CRI和CQI/PMI中的至少之一的部分或者所有信息之外做速率匹配。
可选地,当PUSCH上有HARQ-ACK时,所述HARQ-ACK在sPUCCH的信息写入所述交织矩阵后进行打孔。
可选地,所述sPUCCH上的UCI可以采用独立的调制编码,或者可以采用和PUSCH相同的调制编码方式。
实际应用时,当有超过两种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。为了保证较短TTI长度的PUCCH的时延性能,将TTI长度最短的PUSCH和PUCCH按照上述方式进行处理。比如图3中将具有2个传输符号的sPUCCH和具有4个传输符号的sPUSCH按照本实施中的方法进行处理。1ms的PUSCH放弃传输。
当有多个PUCCH、一个或者多个PUSCH的传输时间有重叠时,可以
只传输所述多个PUSCH中的TTI长度最短的PUSCH,其余信道放弃传输或者推迟传输。可选地,当只有一个PUCCH的TTI长度小于所述多个PUSCH中的TTI长度最短的PUSCH的TTI长度时,将所述PUCCH上的UCI或者指定类型的UCI在所述多个PUSCH中的TTI长度最短的PUSCH上发送,发送方式与本实施例中的上述方式相同。可选地,当有多个PUCCH的TTI长度小于所述多个PUSCH中的TTI长度最短的PUSCH的TTI长度时,将所述多个PUCCH上的UCI或者指定类型的UCI在所述多个PUSCH中的TTI长度最短的PUSCH上发送。发送位置可以是多个PUCCH中TTI长度最短的PUCCH对应的符号。如图6所示。有四个信道的约定传输时间有重叠,其中,PUSCH中最短的TTI长度的PUSCH是7-符号的sPUSCH,则发送7-符号的sPUSCH,其他信道都放弃发送。比7-符号的TTI长度短的PUCCH有两个,即4-符号的sPUCCH和2-符号的sPUCCH,这两个信道上的UCI写入7-符号的sPUSCH,写入的位置是4-符号的sPUCCH和2-符号的sPUCCH中的最短的TTI长度的PUCCH对应的符号,即符号#12和13,即网状部分。
实施例五
与实施例一类似,本实施例中,在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应TTI的长度不同。
在本实施例中,PUSCH的TTI长度大于PUCCH的TTI长度。本实施例以1ms TTI的PUSCH和sTTI的PUCCH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以用于其它TTI长度。
在本实施例中,在sPUCCH对应的符号上,只传输sPUCCH,不传输PUSCH,在PUSCH对应的其余符号上仍传输PUSCH。如图7所示,图7为一个子帧中的14个传输符号,其中sPUCCH占用符号#6、7,斜线部分为DMRS。在该方法中,sPUCCH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。
也就是说,在sPUCCH所在的传输符号上,不传输PUSCH,sPUCCH
所在的传输符号之外的其余PUSCH的信息仍传输。
当PUSCH上包含UCI时,将所述UCI放到sPUCCH上传输。或者,当PUSCH上包含UCI时,且所述UCI所在的符号与sPUCCH对应的符号有重叠时,将所述UCI放到sPUCCH上传输。
可选地,如果所述UCI包含HARQ-ACK,则将所述HARQ-ACK放在sPUCCH上传输,如果所述UCI还包含其他信息,则放弃传输其他信息。
可选地,如果所述UCI包含HARQ-ACK和/或RI/CRI,则将所述HARQ-ACK和/或RI放在sPUCCH上传输,如果所述UCI还包含其他信息,则放弃传输其他信息。比如,当UCI有HARQ-ACK和RI/CRI以及CQI/PMI,可以将HARQ-ACK和RI/CRI放到sPUCCH上传输,将CQI/PMI放弃传输。
可选地,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,将所述HARQ-ACK、RI/CRI和预设类型的CQI/PMI中的至少之一放在sPUCCH上传输,放弃传输其他信息。
为了避免对PUSCH对应的DMRS和/或UCI产生影响,进一步地,当sPUCCH对应的发送符号对应PUSCH上的DMRS和/或UCI时,可以推迟发送sPUCCH。
可选地,当sPUCCH和PUSCH的重叠部分包含DMRS所在的符号时,可以根据sPUCCH和PUSCH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。
实际应用时,当PUSCH上有UCI时,可以采用下述的方法之一进行发送:
第一种方式:完全不考虑sPUCCH对应的传输符号与PUSCH的UCI对应的传输符号的位置关系,只要PUSCH上有UCI时,所述UCI都放到sPUCCH上传输。
可选地,如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUCCH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。
可选地,如果所述UCI包含HARQ-ACK和/或RI/CRI,将所述HARQ-ACK和/或RI放在sPUCCH上传输,如果所述UCI还包含其他信息,
放弃传输其他信息。
可选地,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,将所述HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一放在sPUCCH上传输,放弃传输其他信息。
第二种方式:当PUSCH上有UCI,且sPUCCH对应的传输符号和UCI对应的符号有重叠时,将重叠部分的UCI放到sPUCCH上传输;当和UCI不重叠时,则UCI仍放置在PUSCH上。
这里,符号有重叠是指有部分符号相同。比如,sPUCCH对应的传输符号和HARQ-ACK和/或CSI所在的传输符号重叠,则将HARQ-ACK和/或CSI放到sPUCCH上。如图8所示,当sPUCCH对应前两个传输符号时,如果PUSCH上刚好有RI发送,那么将RI放到PUSCH上传输。
可选地,如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUCCH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。
可选地,如果所述UCI包含HARQ-ACK和/或RI/CRI,将所述HARQ-ACK和/或RI放在sPUCCH上传输,如果所述UCI还包含其他信息,放弃传输其他信息。
可选地,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,将所述HARQ-ACK、RI/CRI和预设类型CQI/PMI中的至少之一放在sPUCCH上传输,放弃传输其他信息。
第三种方式:当sPUCCH对应的传输符号和所述UCI的全部或者部分信息对应的传输符号有重叠时,sPUCCH仍然在所述重叠的传输符号上传输。
第四种方式:当sPUCCH对应的传输符号和所述UCI的全部或者部分信息对应的传输符号有重叠时,则sPUCCH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。
实际应用时,当sPUCCH对应的符号和PUSCH的DMRS所在符号有重叠时,可以采用以下方式传输:
第一种方式:sPUCCH在DMRS所在的传输符号上传输,可以采用剩
下的其他符号上的DMRS对PUSCH进行解调,比如sPUCCH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。
第二种方式:按照sPUCCH和PUSCH频域跨度生成一个DMRS。如图9所示。sPUCCH对应的传输符号是符号#2和3,和第一个时隙的DMRS符号有重叠,此时,按照PUSCH和sPUCCH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所在传输符号,也可以是sPUCCH所在传输符号,图9中DMRS的时域位置是DMRS所在符号。
当有超过两种TTI长度的信道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长度的信道的时延性能,将TTI长度最短的PUSCH和PUCCH按照上述方式进行处理。比如将图3中将具有2个传输符号的sPUSCH和具有4个传输符号的sPUCCH按照本实施中的方法进行处理。
或者,当有超过2个TTI长度的信道的传输时间有重叠时,在一个传输符号上,只传输指定信道,其中,
所述指定信道满足以下条件之一:
在所述两个以上的信道中,只有指定PUSCH的约定传输时间包括所述传输符号;
在所述两个以上的信道中,有多个信道的约定传输时间包括所述传输符号,在所述多个信道中,指定信道对应的TTI长度最小。
图10给出一个示意图,有三种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sPUCCH和2符号的sPUCCH,其中,1ms的PUSCH的约定传输时间是符号#0~13,4符号的sPUCCH的约定传输时间是符号#5~8,2符号的sPUCCH的约定传输时间是符号#7和8。那么,在符号#7和符号8上只传输2符号的sPUCCH,在符号#5和6上只传输4符号的sPUCCH,在其余的符号上,即符号#0~4以及9~13,只传输1ms的PUSCH。
UCI的处理与上述类似,比如PUSCH和sPUCCH上的所有UCI或者指定类型的UCI都在sPUCCH上传输。或者只有被打掉的UCI或者打掉的
指定类型的UCI在sPUCCH上传输。
实施例六
本实施例给出在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应的TTI长度不同。这里,TTI的长度可以是现有LTE系统中的1ms TTI,或者所述TTI包含2个传输符号、4个传输符号、或者7个传输符号等。其中,2个传输符号、4个传输符号、或者7个传输符号可以是物理上连续的,也可以是不连续的。比如TTI长度为2个传输符号时,PUSCH的DMRS在一个子帧上的第一个传输符号上发送,上行数据在该子帧的第三个传输符号上发送。实际应用中TTI的长度不限于本实施例中描述的的TTI长度。在本实施例中,长度小于1ms的TTI又称为sTTI。
在本实施例中,PUSCH的TTI长度小于PUCCH的TTI长度。比如PUCCH的TTI长度为1ms,PUSCH的TTI长度为4个传输符号;或者,PUCCH的TTI长度为4个传输符号,PUSCH的TTI长度为2个传输符号。本实施例以1ms TTI的PUCCH和sTTI的sPUSCH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以用于其它TTI长度的应用场景。
PUCCH上的UCI包括CSI、SR和HARQ-ACK的至少之一。发送sPUSCH,放弃传输PUCCH。可选地,将所述PUCCH上的UCI放到sPUSCH上传输,或者将所述PUCCH上的指定的UCI放到sPUSCH上传输。具体如下。
可选地,如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUCCH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。
可选地,如果所述UCI包含SR,将所述SR放在sPUCCH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。
可选地,如果所述UCI包含HARQ-ACK和/或SR,将所述HARQ-ACK和/或SR放在sPUCCH上传输,如果所述UCI还包含其他信息,放弃传输其他信息。
可选地,如果所述UCI包含HARQ-ACK、SR和预设类型的CSI中的至少之一时,将所述HARQ-ACK、SR和预设类型的CSI中的至少之一放在sPUCCH上传输,放弃传输其他信息。这里,预设类型的CSI可以是宽带CSI,实际应用中不限于该形式的CSI。
比如,PUCCH上信息为:HARQ-ACK和周期CSI反馈,那么HARQ-ACK在sPUSCH上传输,周期CSI反馈不在sPUSCH上传输。
PUCCH上除放到sPUSCH上传输的信息外的其它信息放弃传输。
可选地,放弃传输的所述PUCCH上的信息推迟到之后的子帧上传输。
本实施例中的方法也可以用于2个以上的信道的约定传输时间有重叠时。当多个上行信道中,TTI长度最短的是PUSCH,那么其他PUCCH信道上的UCI或者指定类型的UCI放在所述PUSCH上传输,类似上述。可选地,其他PUSCH信道上,如果也有UCI信息,这些UCI也可以放在sPUSCH上传输。这里,当sPUSCH也包含UCI时,上述的UCI可与sPUSCH上的UCI通过级联的方式进行传输。
实施例七
与实施例六类似,本实施例给出在一个载波上,当PUSCH和PUCCH的约定传输时间有重叠时的信道传输方法,其中这两种信道对应的TTI长度不同。
在本实施例中,PUSCH的TTI长度小于PUCCH的TTI长度。本实施例以1ms TTI的PUCCH和sTTI的sPUSCH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以用于其它TTI长度的应用场景。
在本实施例中,PUCCH和sPUSCH同时传输,即在sPUSCH所在的传输符号上,UE同时发送了2个信道。
其中,所述PUCCH和sPUSCH对应的频域资源不重叠。
所述方式也可用于一个以上的PUCCH和一个以上的PUSCH的约定传输时间有重叠时,当它们对应的频域资源不重叠,则同时发送所有信道。
实施例八
本实施例给出在一个载波上,当多个PUCCH的约定传输时间有重叠时的传输方法,其中这多个PUCCH对应的TTI长度不同。
本实施例以1ms TTI的PUCCH和sTTI的sPUCCH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以用于其它TTI长度。
在本实施例中,UE同时发送PUCCH和sPUCCH,即在sPUCCH所在的符号上,UE同时发送了两个信道。
其中,所述PUCCH和sPUCCH对应的频域资源没有重叠。
实施例九
本实施例给出在一个载波上,当多个PUCCH的约定传输时间有重叠时的信道传输方法。其中这多个PUCCH对应TTI长度不同。
本实施例以1ms TTI的PUCCH和sTTI的sPUCCH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以用于其它TTI长度。
下面给出几种发送方式,可以采用以下方法之一进行发送:
第一种方式:发送sPUCCH,放弃PUCCH的传输,或者,将PUCCH推迟到后面的子帧中进行传输。
第二种方式:发送sPUCCH,将PUCCH上UCI或者指定类型的UCI放到sPUCCH上传输。
可选地,如果所述UCI包含HARQ-ACK,将所述HARQ-ACK放在sPUCCH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中不包含HARQ-ACK,则只在sPUCCH上发送sPUCCH包含的信息。
可选地,如果所述UCI包含SR,将所述SR放在sPUCCH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中不包含SR,则只在sPUCCH上发送sPUCCH包含的信息。
可选地,如果所述UCI包含HARQ-ACK和/或SR,将所述HARQ-ACK
和/或RI放在sPUCCH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SR以及CQI/PMI,可以将HARQ-ACK和SR放到sPUCCH上传输,CQI/PMI放弃传输。
可选地,如果所述UCI包含HARQ-ACK、SR和预设类型CSI中的至少之一时,将所述HARQ-ACK、SR和预设类型的CSI中的至少之一放在sPUCCH上传输,放弃传输其他信息。这里预设类型的CSI可以是某些格式的CSI,比如为宽带CSI。比如当UCI有HARQ-ACK和SR以及之窄带CSI,可以将HARQ-ACK和SR放到窄带sPUCCH上传输,窄带CSI放弃传输。
可选地,如果所述UCI的bit数与所述sPUCCH上的bit数之和超过了sPUCCH能支持的bit数,那么可以采用HARQ-ACK bundling技术。
第三种方式:在sPUCCH所在的传输符号上,不传输PUCCH。在其余符号上,仍然传输PUCCH。
第四种方式:根据sPUCCH的时域位置来确定发送其中某一个信道。举个例子来说,当sPUCCH的最后一个传输符号超过该子帧中的第m个符号时,则发送PUCCH,如果sPUCCH的最后一个传输符号不超过第m个传输符号时,则发送sPUCCH,比如,m=7。也就是说,当sPUCCH位于第一个时隙时,发送sPUCCH,当sPUCCH位于第二个时隙时,发送PUCCH。
可选地,可以根据sPUSCH对应的TTI长度来确定采用上述哪种方式。
可选地,eNB可以给UE配置sPUCCH和PUCCH是否可以同时传输。如果配置了可以同时传输,那么采用实施例八中的方法传输,否则采用本实施例中的一种方式进行传输。
实施例十
本实施例给出CA场景下,当一个或者多个PUCCH和一个或者多个PUSCH的约定传输时间有重叠时的信道传输方法。其中,所述一个或者多个PUCCH的TTI的长度不同,所述一个或者多个PUSCH的约定传输时间不同。
在本实施例中,只传输PUSCH。如果一个PUCCH的TTI长度和其中一个PUSCH的TTI长度相同时,该PUCCH上UCI的全部或者部分信息在与该PUCCH的TTI长度相同的PUSCH上发送。优选地,如果有多个PUSCH与该PUCCH的TTI长度相同,那么按照预设的规则选择PUSCH进行传输,比如,如果所述多个PUSCH中的某一个在主载波上,则在主载波上的PUSCH上发送,或者,如果所述多个PUSCH都在辅载波上,则在其中ScellIndex最小或最大的载波上的PUSCH进行发送。
对于剩下的PUCCH,即没有和其TTI长度相同的PUSCH,那么剩下的PUCCH在指定的PUSCH上发送,比如,如果主载波上有PUSCH,则在主载波上的PUSCH上发送,或者,如果主载波上没有PUSCH,在其中ScellIndex最小或最大的载波上的PUSCH进行发送。或者,选择TTI长度最小的PUSCH进行发送。
下面给出一个例子,一共有2个载波,ScellIndex分别为0和1,每个载波上都有一个PUSCH,其中ScellIndex为0的载波上的PUSCH的TTI长度为4,scellIndex为1的载波上的PUSCH的TTI长度为2,此时有三个PUCCH,TTI长度分别为2、4、7,那么TTI长度为2的PUCCH上的信息在scellIndex为1的载波上发送,TTI长度为2的PUCCH上的信息在scellIndex为0的载波上发送。TTI长度为7的PUCCH可以在TTI最短的PUSCH上发送,即在scellIndex为1的载波上发送。发送的方式可参考前述的实施例。
实施例十一
本实施例给出在CA场景下,当一个或者多个PUCCH和一个或者多个PUSCH的约定传输时间有重叠时的信道传输方法。其中,所述一个或者多个PUCCH的TTI的长度不同,所述一个或者多个PUSCH的约定传输时间不同。
在本实施例中,当一个或者多个PUCCH和一个或者多个PUSCH的约定传输时间有重叠时,发送所有的PUSCH和一个PUCCH。其中,被发送的PUCCH在所述多个PUCCH中的TTI长度最短。可选地,所述被发送的
PUCCH在主载波上传输。
可选地,在所述多个PUCCH中,除了TTI长度最短的PUCCH之外的PUCCH上的UCI或者UCI的指定信息在所述被发送的PUCCH信道上传输,比如只有HARQ-ACK在所述被发送的PUCCH上传输。
实施例十二
本实施例给出在CA场景下,当一个或者多个PUCCH和一个或者多个PUSCH的约定传输时间有重叠时的信道传输方法。其中,所述一个或者多个PUCCH的TTI的长度不同,所述一个或者多个PUSCH的约定传输时间不同。
在本实施例中,发送所有的PUSCH。如果一个PUCCH的TTI长度和其中一个PUSCH的TTI长度相同时,则该PUCCH上的UCI的全部或者部分信息在与该PUCCH的TTI长度相同的PUSCH上发送。优选地,如果有多个PUSCH与该PUCCH的TTI长度相同,那么按照预设的规则选择PUSCH进行传输,比如,如果所述多个PUSCH中的某一个在主载波上,则在主载波上的PUSCH上发送,或者,如果所述多个PUSCH都在辅载波上,则在其中ScellIndex最小或最大的载波上的PUSCH进行发送。
对于剩下的PUCCH,即没有和其TTI长度相同的PUSCH,选择剩下的PUCCH中TTI最小的PUCCH进行发送,而其他PUCCH上的所有或者部分信息也在所述TTI最小的PUCCH进行发送。也就是说发送了所有的PUSCH和一个PUCCH。
下面给出一个例子,一共有2个载波,ScellIndex分别为0和1,每个载波上都有一个PUSCH,其中ScellIndex为0的载波上的PUSCH的TTI长度为4,scellIndex为1的载波上的PUSCH的TTI长度为2,此时有三个PUCCH,TTI长度分别为2、4、7,那么TTI长度为2的PUCCH上的信息在scellIndex为1的载波上发送,TTI长度为2的PUCCH上的信息在scellIndex为0的载波上发送。TTI长度为7的PUCCH单独发送。也就是说发送了TTI长度为7的PUCCH和两个TTI长度分别为2和4的PUSCH。
实施例十三
本实施例给出在一个载波上,当多个PUCCH的约定传输时间有重叠时的信道传输方法。其中这多个PUCCH对应TTI长度不同。根据PUCCH携带的UCI和/或PUCCH的TTI长度确定优先级,选择优先级最高的PUCCH进行发送,放弃发送其余的PUCCH或者将所述其余的PUCCH推迟到约定传输时间之后发送。
根据以下至少之一确定优先级:
1)携带HARQ-ACK的PUCCH的优先级比携带的CSI的PUCCH的优先级高,即当两个PUCCH,一个携带HARQ-ACK,另一个携带CSI时,传输携带HARQ-ACK的PUCCH,放弃传输携带CSI的PUCCH。
2)携带SR的PUCCH的优先级比携带的CSI的PUCCH的优先级高。
3)携带的UCI类型相同的情况下,对应的TTI长度短的PUCCH比对应的TTI长度长的PUCCH的优先级高,比如,TTI长度为1ms的PUCCH和长度为0.5ms的PUCCH都携带HARQ-ACK,那么长度为0.5ms的PUCCH的优先级高。
4)携带HARQ-ACK和/或SR的对应的TTI长度短的PUCCH比携带HARQ-ACK和/或SR的TTI长度长的PUCCH的优先级高。
可选地,将所述其余信道上的UCI放在所述优先级最高的控制信道上传输。
可选地,当所述其余信道上包含指定信息时,将所述指定信息放在所述优先级最高的控制信道上传输。
