LTE使用非授权主要有两种模式,一种是载波聚合(Carrier Aggregation,CA),非授权作为辅助的一个分量载波接入,另一种是采用双连结(Dual Connectivity,DC)的接入模式。在这两种工作模式下,非授权载波上都有可能需要发送物理上行控制信道(Physical Uplink Control Channel,PUCCH)。
相关技术中的LTE的PUCCH支持多种传输格式,包括某个时刻仅占一个资源块(Resource Block,RB)的Format 1/1a/1b/2/2a/2b/3/5以及占连续1~8个RB的format 4。
其中,每种格式的调制方式以及最多能承载的信息比特数目如表1所示。
表1
每种格式支持的上行控制信令组合为:
Normal CP(一般循环前缀)时,对于format 1a,仅能发送1比特HARQ-ACK或1比特的HARQ-ACK和SR组合;
Format 1b可以用来发送2比特的HARQ-ACK或2比特的混合自动重传请求-确认(Hybrid Automatic Repeat Request-Acknowledgement,HARQ-ACK和调度请求(Scheduling Request,SR)组合;
当使能信道选择的时候,Format 1b最多承载4比特的HARQ-ACK反馈:当没有与HARQ-ACK复用时,Format 2用来发送信道质量指示(Channel Quality Indication,CQI)/预编码矩阵指示(Precoding Matrix Indicator,PMI)或秩指示(Rank Indicator,RI);
Format 2a用来发送CQI/PMI或RI与1比特的HARQ-ACK复用;
Format 2b用来发送CQI/PMI或RI与2比特的HARQ-ACK复用;
format 2用来发送CQI/PMI或RI与HARQ-ACK复用;
Format 3用来发送频分双工方式(Frequency Division Duplex,FDD)系统中最多10比特的HARQ-ACK或TDD系统中最多20比特的HARQ-ACK;
Format 4用来发送多个载波的HARQ-ACK和/或者周期信道状态信息
(Channel State Information,CSI);
Format 5用来发送多个载波的HARQ-ACK和/或者周期CSI。
按照国家地区管制的要求,终端在非授权载波进行上行数据(如上行控制信息)传输之前需要先做先听后说(Listen before talk,LBT),也称作空闲信道评估(Clear Channel Assessment,CCA),且发送数据需要满足80%占用带宽及功率谱密度(Power Specturm Density,PSD)的管制要求,但是目前LTE的PUCCH结构仅占系统带宽边界的一个RB,或者连续的几个RB,这样并不能满足管制的要求。
针对相关技术中存在的在非授权载波上进行UCI信息发送时,无法满足地区管制及非授权载波占用带宽的问题,目前尚未提出有效的解决方案。

下面结合具体实施例对本公开中提供的非授权频谱上行控制信息的发送方法做详细说明。
实施例一:
本实施例对PUCCH的资源或结构及配置进行说明。
每个UE分配有一个PUCCH信道,一个PUCCH信道占等间隔离散的M个RB,间隔的RB数目为N。例如对于20M的系统带宽,M和N的值都为10,如图3所示,一个PUCCH信道占编号为0、10、20、30、40、50、60、70、80、90的10个RB,这些RB可以组成一个交织单位,交织单位的编号为0。编号为1的交织单元包括RB1、RB11、RB21、RB31、RB41、RB51、RB61、RB71、RB81、RB91。每个UE的PUCCH信道占一个交织单元,即10个RB。
基站可以通过高层信令半静态配置每个UE的PUCCH资源,或者UE可以通过隐含映射的方式确定自己的PUCCH资源。例如基站通过4比特信令来指示UE PUCCH信道的交织单元编号。0000表示该UE的PUCCH占编号为0的交织单元,包含RB索引为0、10、20、30、40、50、60、70、80、90的RB。1001表示该UE的PUCCH占编号为9的交织单元,包含的RB索引为9、19、29、39、49、59、69、79、89、99。
或者,当PUCCH承载的内容包含ACK/NACK的时候,UE通过ACK/NACK对应的PDSCH子帧的PDCCH的最小CCE索引来确定PUCCH信道的交织单元编号。
PUCCH和PUSCH通过频分的方式占用不同的交织单元,基站调度PUSCH或给UE分配PUSCH资源的时候,避开PUCCH的资源。
实施例二
本实施例对PUCCH采用的格式进行说明。
PUCCH的信道结构如附图4所示,每个PUCCH信道包含多个RB,每个RB所采用的结构仍然是原来R13已有的PUCCH格式。
其中,每个RB所采用的格式可以包括下面两种:
第一种:预定义或者基站高层信令半静态配置某个交织单位仅包含一种format。即,每个RB的format都相同,例如均为format2,或者都为
format2a,或者都为format2b,或者均为format 5,或者均为format4。
第二种:基站配置某个交织单位包含多种format,不同RB采用的格式可以不同。例如,某个交织单元的某些RB是format 1,某些RB是format 2,或者某些RB采用格式3,某些RB采用格式2,或者某些RB采用格式1,某些RB采用格式4或格式5。
基站可以通过分配不同的format实现不同UCI比特数目的发送以及各种格式之间的切换。
相同的RB上不同UE仅能使用相同的格式,以便实现多用户正交复用。
各个UE通过不同交织索引频域复用以及相同交织索引内不同频域扩频码,和/或正交卷积码(Orthogonal Convolutional Code,OCC)在一个交织资源内进行PUCCH资源码分复用。
其中,载波传输的UCI信息可以包括以下至少之一:
一个载波多个进程或多个子帧的ACK/NACK;一个或多个载波的周期CSI信息或者非周期CSI信息;BSR;额外比特用于基站和UE保持ACK/NACK上报同步。
UCI的信息处理过程包括下面两种方式:
方式一:先将UCI信息分组,一个组可能最终映射到多个RB上,不同组映射到不同的RB或通过不同的format承载。
然后每个组的UCI信息按照映射的RB对应的格式所能承载的比特信息对信息进行编码速率匹配,然后是加扰,调制,映射。
方式二:将UCI信息重复在多个RB上发送。每个RB对UCI处理方式根据该RB采用的格式进行处理。
实施例三
本实施例对PUCCH仅包含format 2/2a/2b其中一种,或format 2/2a/2b中的两种或三种格式的情况进行说明。
通过系统预定义方式或基站高层RRC信令配置的方式定义PUCCH的每个RB都是采用format 2/2a/2b的处理方式进行UCI的处理。PUCCH的结构如图5所示。每个RB都用相同的一种格式,例如一个交织单元的所有RB都为格式2,或者都为格式2a或者都为格式2b。或者每个RB采用不同的格式,例如索引为0的RB采用format2,索引为10的RB采用format 2a,索引为20的RB采用format2b。
采用格式2/2a/2b的PUCCH每个子帧都包含4个DMRS符号位置,具体位置跟现有的位置相同。
当UCI包括ACK/NACK、CQI、PMI、RI等CSI信息的时候,可以通过format2/2a/2b发送上行控制信息。具体信息处理过程如下:
将UCI信息等分成10个组,然后每个组映射到不同的RB上面,每个组按照该RB对应的格式进行相应的信息处理,编码,加扰,调制,然后频域乘以一个ZC序列扩频,最后映射到一个RB的相应的SC-OFDM符号上。
其中,每个RB所用的ZC序列的确定方式如下:
方式一:所有RB的ZC序列都相同。
方式二:所有RB的ZC序列的根序列都相同,每个RB采用的循环移位不同。
当多个UE占用相同的RB且ZC根序列相同的时候,所采用的ZC序列的循环移位不同。
方式三:所有RB所用的扩频序列由同一条ZC序列截取得到。
例如,PUCCH占一个交织单元的10个RB,每个RB上扩频用的序列由同一条长度为120的ZC序列,值为N(0)、N(1)、N(2)、N(3)、……N(119)截取不同的位置的12个值得到。交织单元的第一个RB用的序列为这条序列的N(0)~N(11),第二个RB用的序列为N(12)~N(23),依此类推。
当UCI信息小于10比特的时候,处理方式为:
方式一:每个RB都重复传输该UCI信息。即PUCCH包含的所有RB上最终的SC-OFDM符号的内容都相同。
方式二:将UCI信息分成p个组,p小于10,例如p为2或5。然后将每个组重复映射到多个RB上。每个RB的数据按照本RB对应的序列进行扩频。
实施例四
本实施例对上行控制信息通过PUCCH format4进行承载时候的资源映射方式进行说明。
扩展配置PUCCH format 4的原来预留的配置7用于支持PUCCH占一个交织单元,或者离散等间隔的10个RB。然后基站通过高层信令给出该UE的PUCCH占的交织单位的索引。不同UE的PUCCH所占的交织单位的编号不同。或者说该格式下不同UE仅能通过频分的方式复用。
然后不同比特的UCI通过编码速率匹配进行10个RB,12个OFDM符号的数据生成,然后按照现有的format 4的方式进行数据加扰以及QPSK调制处理生成调制符号,然后将这些调制符号映射到离散等间隔的10个RB的SC-OFDM符号上。
例如,高层信令配置某UE的PUCCH所占的交织单元为编号1,则PUCCH信道所占的RB索引为1、11、21、31、41、51、61、71、81、91,映射到子载波的索引包括k=12、13、14……23,……。
PUCCH format4至少承载10个调制符号的UCI信息,当UCI信息小于10个调制符号的时候,采用重复的方式进行发送,即每个RB的相同SC-OFDM符号上的数据都相同。
实施例五
本实施例对PUCCH对应每个RB都为格式5(即,format5)的情形进行说明。
通过系统预定义方式或基站高层无线资源控制(Radio Resource Control,RRC)信令配置的方式定义PUCCH的每个RB都是采用format5的处理方式进行UCI的处理。PUCCH的结构如图6所示。每个子帧包含2个DMRS符号位置,位于符号3和符号10。
在一实施例中,UCI信息处理过程可以如下:
将UCI信息等分成10个组,然后每个组映射到不同的RB上面,每个组按照格式5的方式进行相应的信息处理,编码,加扰,调制,然后映射到SC-OFDMA符号上。
多个UE可以通过配置不同的交织单元频分的方式或者同一频域资源码分的方式实现复用。
实施例六
本实施例对PUCCH支持多种格式时候各种格式之间的切换进行说明。
当PUCCH支持多种格式的时候,可以根据以下之一方式确定所使用的格式。
当UE配置的载波数目小于预定义阈值n1的时候,或者UCI的比特数目小于预定义阈值m1的时候,PUCCH采用format 2/2a/2b。
当UE配置的载波数目大于n1小于预定义阈值n2的时候,或者UCI的比特数目大于m1小于预定义阈值m2的时候,PUCCH采用format 3。
当UE配置的载波数目大于预定义阈值n2的时候,或者UCI的比特数目大于预定义阈值m2的时候,PUCCH采用format 4/5。
当UCI信息仅包含ACK/NACK信息的时候,采用format1a/1b和/或format3或format4或format5。
当UCI信息包含CSI和ACK/NACK复用的时候,采用format2/2a/2b和/或format4或format5。
实施例七
本实施例对比特数目较少的UCI的信息处理进行说明。
当某个载波反馈的UCI比特数目比较少的时候,采用以下方式之一处理:
方式一:转到授权载波主小区PCell发送。
方式二:通过重复的方式发送。
具体的,这些UCI信息重复在多个RB上面发送,具体UCI的信息处理过程根据该RB对应的已有的PUCCH格式进行。
方式三:
所有UCI信息按照预定义的编码方式一起编码,然后通过UE特定的加扰序列加扰,以及通过QPSK调制,然后每个调制符号通过乘以不同RB所对应的不同序列映射到一个SC-OFDM符号的多个RB上,如图7所示。且时隙间不用再支持跳频,每个RB的序列仍然为长度12的CG序列。
在一实施例中,每个RB的序列设计可以如下:
每个RB采用的是同一序列的不同循环移位。不同UE可以第一个RB的循环移位不同,基站配置的时候仅给出第一个RB的循环移位,后续RB都是预定义移位相同的长度,因此后续RB也是正交的。时域上,仍然采用原来基于符号的序列跳频方式。
方式四:所有UCI信息可以按照预定义的编码方式一起编码,然后通过UE特定的加扰序列加扰,以及通过QPSK调制,然后每个调制符号先乘以一个时域扩频序列,然后每个RB再乘以一个长度为12的ZC序列,然后映射到多个SC-OFDM符号上,每个调制符号上仅占一个SC-OFDMA符号的一个RB,如图8所示。时隙间仍然支持跳频获得频率分集增益。
实施例八
在本实施例中,先将UCI按照原来format 3的处理方式进行编码,加扰,调制生成一个RB的映射数据。
然后剩余RB映射的数据处理方法为:离散傅氏变换(Discrete Fourier Transform,DFT)变换之前,对一个RB的y(n)内容进行不同长度的循环移位。
假设将UCI采用format 3的方式生成的符号数据为y(n),第一个RB发送的内容为直接对y(n)进行DFT,第二个及其他RB的内容在进行DFT之前,先对y(n)进行预定义长度的循环移位,不同RB的移位长度不同。
例如第二个RB循环移位长度为1,第三个RB循环移位长度为2,第六个RB发送的内容循环移位长度为6,移位后的y(n)变换为:
该方式下,不同RB发送的初始UCI信息是相同的,只是每个RB在DFT之前对发送的调制处理后的符号进行了循环移位。该方式下,由于相同的内容已经在不同的频率位置发送,因此时隙间不用再支持跳频。
实施例九
本实施例对PUCCH的载波分组方法进行说明。
当UE仅支持两个PUCCH同时发送的时候,载波分组采用以下之一:
方法一:非授权载波为一组,授权载波为一组。每个组一个PUCCH,多个载波的UCI通过一个载波的PUCCH发送。
方法二:授权载波+部分非授权载波一组。剩余的非授权载波一组。
方法三:PCell一组。剩余的载波一组,且非授权载波传输PUCCH仅反馈本载波或者本非授权载波组的ACK/NACK。授权载波的ACK/NACK仅通过PCell反馈。
且非授权载波的UCI比特数目比较少的时候通过授权传输,当比特数目多的时候才通过非授权传输。
当UE能支持三个PUCCH发送的时候,PUCCH所对应的载波分组如
下:
授权载波一个组。部分非授权载波一个组,剩余非授权载波一个组。每个载波的UCI信息通过自己的PUCCH发送。
实施例十
本实施例对UCI中的ACK/NACK跟PDSCH的定时关系进行说明。
当一个子帧可以反馈多个子帧PDSCH对应的ACK/NACK的时候,定时关系通过以下方式之一确定:
方式一:如图9所示,按照上一个下行burst最后一个下行PDSCH子帧加4的原则确定。且n+k子帧反馈上一个下行burst中该UE所有PDSCH子帧的解调结构。
方式二:如图10所示,采用跨突发burst反馈的方式。第N+1个TXOP内的上行子帧反馈第N个TXOP内下行burst中所有PDSCH子帧的解调结果。
实施例十一
本实施例对将上行控制信息时域长度压缩频域资源扩展的发送方法进行说明。
上行控制信息可以映射到两个或三个符号的PUCCH信道上传输。或者通过新的PUCCH传输格式承载。此时不同的PUCCH的资源通过不同的RE或RB频分。每个PUCCH信道占带宽内离散的多个RE或RB。每个UE的PUCCH资源通过基站配置。
此时,PUCCH在子帧中的位置结构有如下三种:
第一种:PUCCH从子帧的中间开始传输,或者PUCCH和下行属于同一子帧,子帧结构如图11所示。上行子帧位于下行部分子帧的结束位置。其中GP为用于上下行转换及UE进行CCA的时间。
第二种:PUCCH位于DL burst之后的16微秒开始,其中16微秒用于
下行到上行转换的收发时间,如图12所示。PUCCH的时域长度为2到4个OFDM符号。
此PUCCH用于传输前一个burst中PDSCH的解调结果,即ACK/NACK信息。
第三种:PUCCH从子帧第一个符号开始传输,时域长度占L个OFDM符号,如图13所示。UE CCA的位置位于子帧的末尾。
UCI的处理过程如下:
如果是传输该PUCCH组对应的ACK/NACK信息,则先对这些载波的ACK/NACK信息进行级联,用1比特或2比特表示每个载波的ACK/NACK。
在一实施例中,当一次反馈同一载波上一个下行(Downlink,DL)burst包含的多个PDSCH对应的ACK/NACK的时候,多个PDSCH的包的ACK/NACK信息也是按照子帧的先后顺序进行级联,然后再多个载波再一起级联。原始信息通过一个序列编码后,然后经过QPSK调制生成调制符号,映射到PUCCH对应的RE上。
当信道还承载信道质量指示(channel quality indicator,CQI)信息的时候,该信息可以是该PUCCH组多个载波的CQI,此时也是先将这多个载波的CQI进行级联,然后通过序列编码,然后将ACK/NACK信息附在编码后的CQI信息之后,然后进行正交相移键控(Quadrature Phase Shift Keying,QPSK)调制生成调制符号。然后按照该PUCCH所占的RE进行资源映射。
频域上,部分子帧的PUCCH所映射的频域位置为等间隔的离散的M个RE或者RB,满足整个频域至少占系统带宽80%的要求。
或者采用类似物理混合自动重传指示信道(Physical Hybrid ARQ Indicator Channel,PHICH)的信息处理方法。
实施例十二
本实施例对UE PUCCH信道的资源分配进行说明。资源包括频域资源
及码域资源。
基站通过高层信令半静态配置PUCCH资源,和/或,UE通过跟对应PDCCH的位置隐含确定PUCCH资源。所述资源包括交织单元编号以及交织单元每个RB内的资源索引。
在本实施例中,可以通过以下两种方式分配PUCCH资源:
方式一:当分配的交织单元包含的RB采用的PUCCH格式都相同的时候,基站仅给出第一个RB的资源索引,其他RB都相同。
方式二:当分配的交织单元包含的RB采用不同的PUCCH格式的时候,基站给出每个RB的资源索引。
对于每个RB采用的码域资源的确定方法为:
当交织单元的每个RB的PUCCH格式都相同且给UE分配的资源索引都相同的时候,每个RB的频域扩频序列的循环移位跟第一个RB的相同,或者每个UE都偏移一个相同大小的循环移位。UE通过基站分配的PUCCH资源隐含得到循环移位的大小。
当所采用的格式包含时域扩频码的时候,UE的时域扩频码通过基站分配的PUCCH资源隐含得到码索引。且其他RB相同格式的扩频码都相同。
当交织单元每个RB包含的PUCCH格式不同或者每个RB的资源索引不同的时候,UE每个RB的频域扩频序列的循环移位和/或时域扩频码按照本RB的资源索引确定。
实施例十三
本实施例对实施例十一中不同时域长度的PUCCH进行说明。
系统可以预定义多种包含不同符号数目的PUCCH结构。例如预定义短PUCCH的符号数目有7个,2个,3个,4个。其他不同符号的短PUCCH可以通过上述不同数目的符号进行组合得到。
例如,如附图14所示。当下行burst的最后一个子帧剩余的符号数目
为11的时候,10个符号可以发送PUCCH。则可以通过发送一个7个符号的PUCCH和3个符号的PUCCH结构来实现。
其中,7个符号的PUCCH结构跟现有的一个时隙的PUCCH结构完全相同。3个符号的PUCCH结构为中间一个为DMRS,两边发送UCI。2个符号的PUCCH结构为一个符号为DMRS,另外一个符号发送UCI。4个符号的PUCCH时域结构为中间两个符号为DMRS,两边为UCI,或者两个DMRS隔开中间放UCI。
