Description

上行控制信息的传输方法、装置 技术领域
本发明涉及通讯领域,特别涉及一种上行控制信息的传输方法和装置。
背景技术
在通讯网络中,时延是一个关键的绩效指标(Key Performance Indicator,KPI),同时也影响着用户的使用体验。随着通讯协议的发展,对时延影响最明显的物理层的调度间隔也越来越小,在最初的宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中,调度间隔是10ms,高速分组接入(High-Speed Packet Access,HSPA)中调度间隔缩短到2ms,长期演进(Long Term Evolution,LTE)中调度间隔缩短到1ms。
小时延的业务需求导致LTE物理层需要引入短传输时间间隔(Transmission Time Interval,TTI)帧结构,以进一步缩短调度间隔,TTI可以从1ms缩短为1符号(symbol)到0.5ms之间。上述提及的符号可以是LTE系统中的一个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。
图1所示为基站数据传输的RTT(Round-Trip Time,传输的来回时间)时延图,如图1所示,基于混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)技术,如果基站在下行(Downlink,简称DL)链路的编号为i的TTI向用户设备传输数据,若用户设备对接收到的该数据正确解调译码,则在上行(uplink,简称UL)链路的编号为i+4的TTI向基站反馈确认字符(Acknowledgement,ACK),若用户设备对接收到的该数据没有正确解调译码,则在编号为i+4的TTI向基站反馈否认字符(Negative Acknowledgment,NACK),而基站则根据编号为i+4的TTI上收到的ACK或NACK决定对下行链路编号为i+8的TTI进行数据新传或重传处理。反馈的ACK或NACK也可以统称为HARQ-ACK信息。在现有技术中,上行链路和下行链路传输的TTI的长度都是1ms。如果引入短TTI传输技术,例如上行链路和下行链路传输的TTI的长度缩短为0.5ms或为1个或多个符号时,可以认为处理时间等比例缩减,同样遵循上述RTT时延。
LTE支持载波聚合技术,即基站把多个载波配置给一个UE来提升UE的数据速率。支持载波聚合技术的UE可能同时检测到多个下行载波上的下行数据,该UE需要同时对该多个下行载波上的下行数据做HARQ的反馈机制。因此需要一个信道可以支持多个下行载波 上下行数据HARQ-ACK的信息。另一方面,为使基站可以在多个下行载波上对UE调度并传输下行数据,UE需要向基站反馈各载波上信道状态信息CSI(Channel State Information)。在一个特定的上行TTI,可能需要同时向基站反馈针对下行调度数据的HARQ-ACK反馈信息和多个载波上的CSI信息。UE还可能向基站发送调度请求信息(Scheduling Request,SR),用于向基站请求上行UL-SCH资源。
当UE支持多个不同TTI长度的下行载波数据接收时,可能需要在一个特定的上行TTI向基站反馈针对下行调度数据的HARQ-ACK反馈信息和多个载波上的CSI信息。由于不同下行载波上的TTI长度不同,导致不同下行载波上的HARQ-ACK反馈时序和CSI反馈时序对应的时延可能不同,从而可能导致UE需要在该特定的上行TTI内传输不同下行TTI长度对应的HARQ-ACK信息和CSI信息。以HARQ-ACK反馈时序为例,图2所示为不同TTI长度的载波对应的数据传输RTT时延图。如图2所示,图2包括一个上行载波(Component carrier,分量载波,简称CC)和两个下行载波,两个下行载波分别为下行载波1和下行载波2。下行载波1和上行载波的TTI时长相等,下行载波2与下行载波1的TTI时长不相等。如果基站在下行载波1的编号为i+2的TTI上发送数据,则UE收到数据后会在上行载波的编号为i+6的TTI上反馈上行控制信息;如果基站在下行载波2的编号为i的TTI上发送数据,则UE收到数据后,会在下行载波2的编号为i+4的TTI对应的时刻,即在上行载波的编号为i+6的TTI上反馈上行控制信息,即在上行载波的编号为i+6的TTI上可能会发生HARQ-ACK信息的反馈冲突。
现有技术中,还没有当出现多个对应不同长度的时域资源的上行控制信息且其对应的时域资源上发生冲突时上行控制信息怎么传输的处理方法。

为了全面理解本发明,在以下详细描述中提到了众多具体的细节,但是本领域技术人员应该理解,本发明可以无需这些具体细节而实现。在其他实施例中,不详细描述公知的方法、过程、组件和电路,以免不必要地导致实施例模糊。
本发明实施例提供了一种上行控制信息的传输方法和装置,可以解决当出现多个对应不同长度的时域资源的上行控制信息且其对应的时域资源上发生冲突时上行控制信息的传输问题。
下面简要介绍本发明实施例的应用环境,以LTE系统或LTE-A系统为例,但本发明实施例的应用环境不限于LTE相关系统,任何通过调度进行数据传输的无线通信系统都可以采用本发明实施例提供的方案。
可以理解的是,在LTE或LTE-A系统中,从时间维度上来看,一个无线帧的时间长度为10ms,一个子帧的时间长度为1ms,一个无线帧包含10个子帧。具体有两种子帧格式:一种是正常循环前缀(Normal Cyclic Prefix,NCP)子帧格式,一个NCP子帧包括14个OFDM符号或2个时隙;将OFDM符号从0开始标号至13,第0号至第6号OFDM符号为奇数时隙,第7号至第13号OFDM符号为偶数时隙。另一种是长循环前缀(Extended Cyclic Prefix,ECP)子帧格式,一个ECP子帧包括12个OFDM符号或2个时隙;将OFDM符号从0开始标号至11,第0号至第5号OFDM符号为奇数时隙,第6号至第11号OFDM符号为偶数时隙。
从频率维度上来看,最小单位是子载波。从时频二维联合来看,对于一个天线端口传输使用的资源,最小单位是资源单位(Resource Element,RE),一个RE在时域上包含一个OFDM符号,在频域上包含一个子载波。资源单元组(Resource-Element Group,REG)可以包含整数个RE,例如,一个REG可以包含4个或16个RE。一个物理资源块(Physical Resource Block,PRB)在时域上包含一个时隙,在频域上包含12个子载波;一个子帧中包含一个PRB对(PRB pair)。一个资源块(Resource Block,RB)在时域上包含一个子帧,在频域上包含12个子载波。资源块组(Resource Block Group,RBG)可以包含整数个PRB,例如,一个RBG可以包含1个,2个,3个,4个或其他整数个PRB。
上行符号称为单载波频分多址(Single Carrier-Frequency Division Multiple Access,简称SC-FDMA)符号,下行符号称为正交频分复用(Orthogonal Frequency Division Multiplexing,简称OFDM)符号。若后续技术引入正交频分多址(Orthogonal Frequency Division Multiple  Access,OFDMA)的上行多址方式,上行符号也可以称为OFDM符号。本发明实施例中,上行符号和下行符号都统称为符号。一个符号包括循环前缀(Cyclic Prefix,CP)部分和信息段部分,其中信息段部分包括了一个符号的全部信息;CP是对一部分信息段信号的重复。本发明实施例的技术方案中提及的符号也可以是其他类型的通信的符号,本发明对此不作限定。
物理信道(physical channel)具体用于数据信息和/或控制信息的传输,本发明实施例中,物理信道包括以下之一或者组合:PUSCH(physical uplink shared channel,PUSCH,物理上行共享信道),PUCCH(physical uplink control channel,物理上行控制信道),PDCCH(Physical Downlink Control Channel,物理下行控制信道),EPDCCH(Enhanced-Physical Downlink Control Channel,增强的物理下行控制信道),PCFICH(Physical Control Format Indicator Channel,物理控制格式指示信道),PHICH(Physical hybrid ARQ indicator channel,物理混合重传指示信道),PDSCH(Physical Downlink Shared Channel,物理下行共享信道)等,或是标准中新引入的功能相同,但是名称不同的信道,例如短TTI传输中引入的控制信道或数据信道等。
短TTI数据传输即TTI小于1个子帧或1ms的数据传输,例如TTI长度为0.5ms,或者TTI长度为1个、2个、3个、4个、5个、6个符号中的一种,或者TTI长度是1个、2个、3个、4个、5个、6个、7个符号中至少两种不同TTI长度的组合,例如1ms内包含4个TTI,长度分别是4个、3个、4个、3个符号或3个、4个、3个、4个符号或其他不同TTI长度的组合。为描述方便,对于1ms内包含4个TTI的情况,如无特殊说明,在本发明实施例中描述为TTI长度为0.25ms。同理,TTI小于1个子帧或1ms的数据包称为短TTI数据包。短TTI数据传输在频域上可连续分布,也可非连续分布。需要说明的是,考虑到后向兼容性,系统中可能同时存在1ms TTI传输和短TTI传输的情况。
图3示出了可以应用本发明实施例提出的方案的一种应用场景,场景中包括小区基站301,处在小区基站301覆盖范围内并与小区基站301进行通信的用户设备302和用户设备303;其中,小区基站301是LTE系统的基站,用户设备302和303是对应的LTE系统的用户设备,小区基站301和用户设备302均为支持短TTI传输的设备,用户设备303为不支持短TTI传输的设备。小区基站301可以分别使用短TTI或正常的1ms TTI和用户设备302进行通信。小区基站301可以使用正常的1ms TTI和用户设备303进行通信。
在本发明实施例中,用户设备(User Equipment,UE)可称之为终端(Terminal)、移 动台(Mobile Station,MS)、移动终端(Mobile Terminal)等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等,例如,用户设备还可以是便携式、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音和/或数据。
在本发明实施例中,基站可以是LTE系统或者LAA-LTE系统中的演进型基站(Evolutional Node B,缩写为eNB或e-NodeB)、宏基站、微基站(也称为“小基站”)、微微基站、接入站点(Access Point,AP)或传输站点(Transmission Point,TP)、或是其他的网络侧设备等,本发明对此并不限定。
在LTE系统中支持载波聚合技术,即基站把多个载波配置给一个UE来提升UE的数据速率。支持载波聚合技术的UE可能同时检测到多个下行载波上的下行数据,该UE需要同时对该多个下行载波上的下行数据做HARQ的反馈机制。因此需要一个上行信道可以支持多个下行载波上下行数据对应的上行HARQ-ACK信息的传输。另一方面,为使基站可以在多个下行载波上对UE调度并传输下行数据,UE需要向基站反馈各载波上的信道状态信息CSI(Channel State Information,CSI)。UE向基站反馈的CSI信息分为周期CSI信息和非周期CSI信息。对于周期CSI,每个下行载波的反馈周期独立配置,当有多个下行分量载波的周期CSI需要同时反馈时,UE只反馈某一个分量载波上具有最高优先级的周期CSI,其中对于具有相同优先级的多个下行分量载波的周期CSI,反馈下行分量载波索引最小的分量载波的周期CSI。而对于非周期CSI,使用动态下行控制信息DCI中的控制位用于触发非周期CSI。在一个特定的上行TTI,UE可能需要同时向基站反馈针对下行调度数据的上行HARQ-ACK反馈信息和多个载波上的CSI信息。UE还可能向基站发送调度请求信息(Scheduling Request,SR),用于向基站请求上行UL-SCH资源。需要说明的是,下行传输数据块对应的上行HARQ-ACK信息,对下行信道状态测量得到的CSI反馈信息和UE发送的调度请求SR信息都是上行控制信息(Uplink Control Information,UCI),其中CSI反馈信息可以包括CQI(Channel Quality Indicator,信道质量指示)信息、PMI(Precoding Matrix Indicator,预编码矩阵指示)信息、RI(Rank Indicator,秩指示)信息中的至少一种。UCI可以承载在PUCCH上,也可以承载在PUSCH上,本发明实施例主要考虑UCI承载在PUCCH上的情况。
LTE系统中,通常基站会给UE配置PUCCH信道资源和PUCCH格式,PUCCH信道资源用于UE传输UCI。其中,一个PUCCH信道资源对应一种PUCCH格式,UE在该PUCCH信道 资源上根据相应的PUCCH格式传输上行控制信息。LTE系统定义了几种不同的PUCCH格式,下面简要介绍几种不同的PUCCH格式,需要说明的是,这些PUCCH格式都是长度为1ms的PUCCH格式。
PUCCH格式1:
占用1个RB,只携带SR信息,且不占用任何无线资源。UE只有在请求上行资源时,才需要发送SR;其它时候UE不发送SR以节约电量和减少干扰。因此与HARQ-ACK信息不同,并没有明确的比特用于发送SR,而是通过对应的PUCCH上是否存在能量来表示是否存在SR。PUCCH格式1的信道资源是通过高层信令配置给UE的。
PUCCH格式1a:
占用1个RB,只传输1比特的HARQ-ACK信息,使用二进制相移键控(Binary Phase Shift Keying,BPSK)调制,对应单小区、单码字的场景。如果同时需要发送SR,还可以携带SR信息。PUCCH格式1a的信道资源是通过调度下行数据传输的PDCCH的第一个控制信道单元(Control Channel Element,CCE)的指示信息隐式通知给UE的。
PUCCH格式1b:
占用1个RB,传输2比特的HARQ-ACK信息,使用正交相移键控(Quadrature Phase Shift Keying,QPSK)调制,对应单小区、双码字的场景。如果同时需要发送SR,还可以携带SR信息。PUCCH格式1b的信道资源是通过调度下行数据传输的PDCCH的第一个CCE的指示信息隐式通知给UE的。
PUCCH格式2:
占用1个RB,对于正常CP子帧格式而言,只携带编码后20比特的CSI信息;对于长CP子帧格式而言,不仅携带20比特的CSI信息,还可以携带1比特或2比特的HARQ-ACK信息。二者均采用QPSK调制。
PUCCH格式2a:
占用1个RB,传输CSI信息和HARQ-ACK信息。只支持正常CP子帧格式,携带编码后20比特的CSI信息和1比特的HARQ-ACK信息,对应单小区、单码字的场景,其中,CSI信息使用QPSK调制,HARQ-ACK信息使用BPSK调制。
PUCCH格式2b:
占用1个RB,传输CSI信息和HARQ-ACK信息。也只支持正常CP子帧格式,携带编码 后20比特的CSI信息和2比特的HARQ-ACK信息,对应单小区、双码字的场景,其中,CSI信息和HARQ-ACK信息均使用QPSK调制。
PUCCH格式2/2a/2b的信道资源是通过高层信令配置给UE的。假设UE被配置了PUCCH格式2,当UE仅传输CSI信息时,使用PUCCH格式2;当UE需要同时传输CSI信息和HARQ-ACK信息时,正常CP子帧格式下使用PUCCH格式2a或2b,长CP子帧格式下使用PUCCH格式2。
PUCCH格式3:
占用1个RB,携带编码后48比特的信息,可支持最多5个服务小区且UE在每个服务小区都被配置了MIMO的场景下的HARQ-ACK发送。在同时有SR需要传输时,也可以支持传输HARQ-ACK的同时传输SR。并且在容量允许的情况下传输最多一个载波的CSI信息。PUCCH格式3的信道资源是通过高层信令配置4种可能的信道资源给UE,然后用动态信令指示UE具体使用4种信道资源中的哪一种。
PUCCH格式4:
是基于PUSCH的PUCCH格式,PUCCH信道资源占用N(1≤N≤8)个RB。PUCCH格式4的信道资源是通过高层信令配置4种可能的信道资源给UE,然后用动态信令指示UE具体使用4种信道资源中的哪一种。
PUCCH格式5:
是基于PUSCH的PUCCH格式,PUCCH信道资源占用1个RB,允许两个用户码分复用。PUCCH格式5的信道资源是通过高层信令配置4种可能的信道资源给UE,然后用动态信令指示UE具体使用4种信道资源中的哪一种。
在现有的LTE系统中,不同格式的PUCCH的信道结构不同。对于同一种PUCCH信道结构,1ms TTI长度的PUCCH包含2个时隙,采用时隙间跳频的方式传输,每个时隙的信道结构完全相同。具体的,以正常CP子帧格式下的奇数时隙为例,PUCCH格式1或1a或1b的信道结构为符号0,符号1,符号5和符号6用于传输信息比特,用序列长度为4的正交掩码(Orthogonal Cover Code,OCC)扩频;符号2,符号3和符号4用于传输参考信号,用序列长 度为3的OCC扩频。PUCCH格式2的信道结构为符号1和符号5用于传输参考信号,其余的5个符号用于传输信息比特,其中,同一个符号上的12个子载波上承载相同的内容,同一个时隙内不同的符号上承载不同的内容,不同时隙内不同的符号上也承载不同的内容。对于PUCCH格式2a或2b,则是在PUCCH格式2的信道结构的基础上,将HARQ-ACK信息调制在用于传输参考信号的符号5上。PUCCH格式3的信道结构和PUCCH格式2的信道结构相同,符号1和符号5用于传输参考信号,其余的5个符号用于传输信息比特,区别在于格式3中一个时隙内同一个符号上的12个子载波每个载波承载不同的内容,同一个时隙内不同的符号上承载相同的内容但使用序列长度为5的OCC时域扩频使其有不同的表现形式,不同时隙上承载不同的内容。PUCCH格式4或5的信道结构和1ms TTI的PUSCH相同,每个PRB的中间一个符号为解调参考信号,原始信息比特进行信道编码和调制后映射到除解调参考信号外的其他位置,在该格式中的原始比特信息可以用卷积码编码的方式,例如咬尾卷积码(Tail Biting Convolutional Code,TBCC)。
需要说明的是,现有的PUCCH格式都是基于1ms TTI的。如果上行引入短TTI的传输,相应的,需要新的支持短TTI传输的上行控制信道,例如短PUCCH的信道结构或新的PUCCH格式。
引入短TTI传输后,UE可以支持多种不同TTI长度的下行数据接收,其中,每个TTI里传输的都可以是能独立被解调的完整的传输数据块。UE也可以支持多种不同TTI长度的上行数据发送。下行传输和其对应的上行传输的TTI长度可以相同,例如下行传输和其对应的上行传输的TTI长度都是0.25ms;下行传输的TTI长度可以小于其对应的上行传输的TTI长度,例如下行传输的TTI长度是2个符号,上行传输的TTI长度是3个符号;下行传输的TTI长度还可以大于其对应的上行传输的TTI长度,例如下行传输的TTI长度是0.25ms,上行传输的TTI长度是1个符号。需要说明的是,多个对应不同TTI长度的下行传输数据块可以来自于同一个载波,也可以来自于不同的载波。当UE有多个下行载波时,UE还需要反馈不同载波上的CSI信息。TTI缩短后,对应的HARQ处理时延也会缩短。可以认为HARQ处理时延等比例缩短,即短TTI的数据传输仍然遵循4倍TTI长度的HARQ反馈时延,也可以认为短TTI的数据传输遵循大于4倍TTI长度的HARQ反馈时延或小于4倍TTI长度的HARQ反馈时延,本发明对此并不限定。但不论哪种情况,都可能出现UE需要在上行同一时间向基站反馈至少两种上行控制信息的场景,从而可能出现上行控制信息传输发生冲突。下面对该问题进行详细描述,为描述方便,以载波聚合场景中UE对不同TTI长度的下行载波反馈对应的上 行HARQ-ACK信息进行说明,在该例子中,短TTI的数据传输遵循4倍TTI长度的HARQ反馈时延,并假设上行传输的TTI长度和其对应的下行传输的TTI长度相同。
如图4所示,UE支持两个下行载波数据接收和一个上行载波数据发送,其中两个下行载波分别为下行载波1和下行载波2。其中,下行载波1和上行载波的TTI长度大于下行载波2的TTI长度,且下行载波1的TTI和上行载波的TTI长度相等。假设下行载波1的一个TTI的时长等于N个下行载波2的TTI的时长。即,假设下行载波2的TTI的时长为L2,则下行载波1的TTI的时长L1=N*L2,图4所示的实施例中,L1=2*L2。
图4中每一个长方体代表对应上行数据或下行数据的一个TTI,即,4101为下行载波1的TTI,4201为上行载波的TTI,4301为下行载波2的TTI。如图4所示,4101的TTI的时长等于4201的TTI的时长,4101的TTI的时长等于4301TTI时长的2倍。
下行载波1的TTI和上行载波的TTI时长相等,因此,下行载波1的第k个TTI上的数据对应的HARQ-ACK信息,会在下行载波1的第k+4个TTI对应的上行载波的TTI上反馈,下行载波1会在第k+8个TTI上重传数据或新传数据。例如在4101上的数据对应的HARQ-ACK信息,会在4105对应的4205上反馈,并且在4109上重传数据或新传数据。
上行载波的TTI的时长是下行载波2的TTI时长的2倍,下行载波2的第k个TTI上的数据对应的HARQ-ACK信息,应在下行载波2的第k+4个TTI对应的上行载波的TTI上反馈。例如在4301上的数据对应的HARQ-ACK信息,按HARQ时序应在4305对应的4203的前半部分上反馈上行控制信息,在4306上的数据,按HARQ时序应在4205的后半部分反馈上行控制信息。
在图4所示的实施例中,上行载波上的反馈信息可能产生冲突,冲突类型可能包括:
1)下行载波1的4101以及下行载波2的4305上同时有UE的数据传输,则UE在上行载波的4205上反馈的控制信息会产生冲突;或者,若下行载波1的4101以及下行载波2的4306上同时有数据传输,则在上行载波的4205上反馈的控制信息会产生冲突。
2)下行载波1的4101、下行载波2的4305以及下行载波2的4306上同时有UE的数据传输,则UE在上行载波的4205上反馈的控制信息会产生冲突。
图5所示为上行载波反馈的控制信息产生冲突的示意图上行载波,图5所示的场景中,包括一个上行载波,两个下行载波,两个下行载波分别为下行载波1和下行载波2。其中,下行载波1的TTI长度大于上行载波及下行载波2的TTI长度,下行载波1的TTI时长为下行载波2的TTI时长的2倍,下行载波2的TTI时长与上行载波的TTI时长相等。
下行载波1的5101上传输的数据对应的HARQ-ACK信息,会在上行载波的5209及5210反馈;下行载波2的5305上传输的数据对应的HARQ-ACK信息,会在5209上反馈,下行载波2的5306上传输的数据对应的HARQ-ACK信息,会在5210上反馈。
图5所示的场景中,上行载波上的反馈的控制信息可能产生冲突,冲突类型可能包括:
3)下行载波1的5101以及下行载波2的5305上同时有UE的数据传输,则UE在上行载波的5209上反馈的控制信息会产生冲突;或者,若下行载波1的5101以及下行载波2的5306上同时有数据传输,则在上行载波的5210上反馈的控制信息会产生冲突。
4)下行载波1的5101、下行载波2的5305、下行载波2的5306上均有UE的数据传输,则UE在上行载波的5209及5210上同时产生冲突。
如果以上述不同长度的TTI中最短TTI的时长作为一个时长单位,则实际上,上述冲突类型1)和3)是相同的,冲突类型2)和4)是相同的。为了便于描述,下文中以冲突1)和冲突2)来代表两种冲突类型。
本发明实施例针对上述冲突类型提出了具体的解决方案,下面结合附图对本发明的实施例进行详细描述。

本发明实施例中,根据第三上行控制信息的内容的不同,作为可选的,具体有以下几种情形。
情形一:第三上行控制信息包括第四上行控制信息,即第三上行控制信息包括第一上行控制信息的部分或全部。
即,用户设备在第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源中重叠的时域资源上不传输第二上行控制信息,从而在该重叠的时域资源上只传输第一上行控制信息的部分或全部。
需要说明的是,上行控制信息包括混合自动重传请求信息、信道状态信息、调度请求信息中的至少一种,其中混合自动重传请求信息是对用户设备接收到的下行数据包的应答信息,调度请求信息是向基站请求上行传输资源的信息,信道状态信息是向基站上报用户设备的下行信道状态的信息。一般情况下,当上行控制信息包括上述三种信息中的至少两种时,可以认为混合自动重传请求信息和/或调度请求信息的优先级高于信道状态信息。
可选的,当第一上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种,以及信道状态信息时,第三上行控制信息包括第一上行控制信息的部分可以指第三上行控制信息包括第一上行控制信息中除信道状态信息外的其他部分。
可选的,当第一上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种而第二上行控制信息包括信道状态信息且不包括混合自动重传请求信息和调度请求信息时,第三上行控制信息包括第一上行控制信息的部分或全部。
下面以图7为例具体说明情形一。图7所示为本发明实施例的同一个上行载波上第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠时的示意图。如图7所示,假设第一上行控制信息对应的时域资源的长度为2个符号,具体对应符号0和符号1,用于传输第一上行控制信息;第二上行控制信息对应的时域资源的长度为4个符号,具体对应符号0,1,2,3,用于传输第二上行控制信息。第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源在符号0和符号1上有重叠。其中,符号0和符号1用7209表示,符号2和符号3用7210表示。在图7所示的例子中,第一上行控制信息对应的资源与第二上行控制信息对应的资源在频域上没有重叠。
用户设备原应在第一上行控制信息对应的资源上传输第一上行控制信息,在第二上行控制信息对应的资源上传输第二上行控制信息。当第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠,由于用户设备上行发送的单载波特性,并考虑到第二上行控制信息对应的时域资源的长度大于第一上行控制信息对应的时域资源的长度,用户设备在重叠的时域资源上,例如图7中7209表示的符号上传输第一上行控制信息的部分或全部。相应的,用户设备在第二上行控制信息对应的时域资源中不包括该重叠的时域资源的时域资源上,例如图7中7210表示的符号上传输第二上行控制信息的部分或全部。用户设备在该重叠的时域资源上,例如图7中7209表示的符号上不传输第二上行控制信息。
可选的,用户设备在重叠的时域资源上传输第一上行控制信息的部分或全部可以为用户设备在重叠的时域资源中第一上行控制信息对应的资源上传输第一上行控制信息的部分或全部。例如用户设备在图7中72091表示的资源上传输第一上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源上传输第一上行控制信息的部分或全部可以为用户设备在重叠的时域资源中第二上行控制信息对应的资源上传输第一上行控制信息的部分或全部。例如用户设备在图7中72092表示的资源上传输第一上行控制信息的部分或全部。
图7中,左上角的四个长方形框为72091,左下角的四个长方形框为72092。
情形二:第三上行控制信息包括第五上行控制信息,即第三上行控制信息包括第二上行控制信息的部分或全部。
即,用户设备在第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源中重叠的时域资源上不传输第一上行控制信息,从而在该重叠的时域资源上只传输第二上行控制信息的部分或全部。
如情形一中所述,一般情况下,当上行控制信息包括混合自动重传请求信息、调度请求信息、信道状态信息等三种信息中的至少两种时,可以认为混合自动重传请求信息和/或调度请求信息的优先级高于信道状态信息。
可选的,当第二上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种,以及信道状态信息时,第三上行控制信息包括第二上行控制信息的部分指第三上行控制信息包括第二上行控制信息中除信道状态信息外的其他部分。
可选的,当第二上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种而第一上行控制信息包括信道状态信息且不包括混合自动重传请求信息和调度请求信息 时,第三上行控制信息包括第二上行控制信息的部分或全部。
下面同样以图7为例说明具体说明情形二。如图7所示,假设第一上行控制信息对应的时域资源的长度为2个符号,具体对应符号0和符号1,用于传输第一上行控制信息;第二上行控制信息对应的时域资源的长度为4个符号,具体对应符号0,1,2,3,用于传输第二上行控制信息。第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源在符号0和符号1上有重叠。其中,上行载波上的符号0和符号1用7209表示,上行载波上的符号2和符号3用7210表示。在图7所示的例子中,第一上行控制信息对应的资源与第二上行控制信息对应的资源在频域上没有重叠。
用户设备原应在第一上行控制信息对应的资源上传输第一上行控制信息,在第二上行控制信息对应的资源上传输第二上行控制信息。当第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠,由于用户设备上行发送的单载波特性,用户设备可以在重叠的时域资源上,例如图7中7209表示的符号上传输第二上行控制信息的部分或全部。相应的,用户设备在该重叠的时域资源上,例如图7中7209表示的符号上不传输第一上行控制信息。如果第一上行控制信息对应的时域资源中的全部时域资源与第二上行控制信息对应的时域资源中的部分时域资源有重叠,用户设备可以丢掉第一上行控制信息的传输。如果第一上行控制信息对应的时域资源中的部分时域资源与第二上行控制信息对应的时域资源中的部分时域资源有重叠,用户设备在第一上行控制信息对应的时域资源中不包括该重叠的时域资源的时域资源上传输第一上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源上传输第二上行控制信息的部分或全部可以为用户设备在重叠的时域资源中第一上行控制信息对应的资源上传输第二上行控制信息的部分或全部。例如用户设备在图7中72091表示的资源上传输第二上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源上传输第二上行控制信息的部分或全部可以为用户设备在重叠的时域资源中第二上行控制信息对应的资源上传输第二上行控制信息的部分或全部。例如用户设备在图7中72092表示的资源上传输第二上行控制信息的部分或全部。
情形三:第三上行控制信息包括第四上行控制信息和第五上行控制信息。即第三上行控制信息包括第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
即,用户设备在第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源中重叠的时域资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部 分或全部。
如情形一中所述,一般情况下,当上行控制信息包括混合自动重传请求信息、调度请求信息、信道状态信息等三种信息中的至少两种时,可以认为混合自动重传请求信息和/或调度请求信息的优先级高于信道状态信息。
可选的,当第一上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种,以及信道状态信息时,第三上行控制信息包括第一上行控制信息的部分指第三上行控制信息包括第一上行控制信息中除信道状态信息外的其他部分。可选的,当第二上行控制信息包括混合自动重传请求信息或调度请求信息中的至少一种,以及信道状态信息时,第三上行控制信息包括第二上行控制信息的部分指第三上行控制信息包括第二上行控制信息中除信道状态信息外的其他部分。
下面同样以图7为例说明具体说明情形三。如图7所示,假设第一上行控制信息对应的时域资源的长度为2个符号,具体对应符号0和符号1,用于传输第一上行控制信息;第二上行控制信息对应的时域资源的长度为4个符号,具体对应符号0,1,2,3,用于传输第二上行控制信息。第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源在符号0和符号1上有重叠。其中,上行载波上的符号0和符号1用7209表示,上行载波上的符号2和符号3用7210表示。在图7所示的例子中,第一上行控制信息对应的资源与第二上行控制信息对应的资源在频域上没有重叠。
用户设备原应在第一上行控制信息对应的资源上传输第一上行控制信息,在第二上行控制信息对应的资源上传输第二上行控制信息。当第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠,用户设备可以在重叠的时域资源上,例如图7中7209表示的符号上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源中第一上行控制信息对应的资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。例如用户设备在图7中72091表示的资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源中第二上行控制信息对应的资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。例如用户设备在图7中72092表示的资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源中第一上行控制信息对应的资源上传输第一上行 控制信息的部分或全部,在重叠的时域资源中第二上行控制信息对应的资源上传输第二上行控制信息的部分或全部。例如用户设备在图7中72091表示的资源上传输第一上行控制信息的部分或全部,在图7中72092表示的资源上传输第二上行控制信息的部分或全部。
可选的,用户设备在重叠的时域资源上可以通过频分复用或码分复用的方式传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。可选的,用户设备在重叠的时域资源上可以通过联合编码或分别对第一上行控制信息和第二上行控制信息编码的方式传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。可选的,用户设备在重叠的时域资源上还可以通过时分复用的方式传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。例如在图7所示的实施例中,用户设备在符号0上传输第一上行控制信息的部分或全部,在符号1上传输第二上行控制信息的部分或全部。
由于用户设备可以将第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部通过联合编码或码分的方式复用,进一步可选的,用户设备可以在第一上行控制信息对应的资源上,和/或在第二上行控制信息对应的资源上传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
需要说明的是,在具体的实施例中,可以使用上述三种情形描述的解决方案中的一种或多种来解决前面提出的冲突1)或冲突2)的技术问题。
本发明实施例中,情形一用户设备在重叠的时域资源上仅传输第一上行控制信息的部分或全部,由于第二上行控制信息对应的时域资源的长度大于第一上行控制信息对应的时域资源的长度,用户设备可以在第二上行控制信息对应的时域资源中不包括该重叠的时域资源的时域资源上发送第二上行控制信息的部分或全部,从而可以保证第一上行控制信息和第二上行控制信息中优先级较高的上行控制信息都可以得到传输;情形二用户设备在重叠的时域资源上仅传输第二上行控制信息的部分或全部,可以保证第二上行控制信息中优先级较高的上行控制信息可以得到较多的传输资源,从而保证其解调性能;情形三在重叠的时域资源上通过复用的方式传输第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部,可以保证第一上行控制信息和第二上行控制信息中优先级较高的上行控制信息都可以得到传输。
对于使用一种情形来解决问题的情况可以参见前面的描述,此处不再赘述。下面对使用两种情形来解决问题的情况给出实施例说明,该实施例具体可以对应冲突2)的技术问题。
具体的,以图8为例说明。图8所示为本发明实施例的同一个上行载波上第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠的示意图。如图8所示,假设第一上行控制信息对应的时域资源的长度为2个符号,UE被配置了两个时域连续的用于传输第一上行控制信息的资源,其中,第一上行控制信息对应的资源1具体对应符号0和符号1,用于传输第一上行控制信息1,第一上行控制信息对应的资源2具体对应符号2和符号3,用于传输第一上行控制信息2;第二上行控制信息对应的时域资源的长度为4个符号,具体对应符号0,1,2,3,用于传输第二上行控制信息。第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源在符号0,1,2,3上都有重叠。其中,上行载波上的符号0和符号1用8209表示,上行载波上的符号2和符号3用8210表示。在图8所示的例子中,第一上行控制信息对应的资源与第二上行控制信息对应的资源在频域上没有重叠。
可选的,用户设备在准备8209上需要传输的内容时,发现第一上行控制信息1和第二上行控制信息冲突,考虑到第一上行控制信息1仅能在8209上传输,第二上行控制信息可以在8209和8210上传输,因此在重叠的时域资源8209上,用户设备可以使用情形一,即在8209上传输第一上行控制信息1而放弃传输第二上行控制信息;用户设备在准备8210上需要传输的内容时,发现第一上行控制信息2和第二上行控制信息冲突,这时,第一上行控制信息2和第二上行控制信息都只能在8210上传输,因此在重叠的时域资源8210上,用户设备可以使用情形三,即通过复用的方式传输第一上行控制信息2和第二上行控制信息。
可选的,用户设备确定第一上行控制信息2和第二上行控制信息的优先级高于第一上行控制信息1,因此在重叠的时域资源8209上,用户设备可以使用情形二,即在8209上传输第二上行控制信息而放弃传输第一上行控制信息1;由于已经在8209上传输第二上行控制信息,在重叠的时域资源8210上,用户设备可以使用情形一,即在8210上传输第一上行控制信息2而放弃传输第二上行控制信息,或者用户设备在8210上使用情形三,即通过复用的方式传输第一上行控制信息2和第二上行控制信息。
可选的,用户设备确定第一上行控制信息1和第二上行控制信息的优先级高于第 一上行控制信息2,类似的,在重叠的时域资源8209上,用户设备可以使用情形一或情形三,在重叠的时域资源8210上,用户设备可以使用情形二。
本发明实施例中,使用上述三种情形描述的解决方案中的至少两种来解决前面提出的冲突1)或冲突2)的技术问题,可以保证发生冲突的上行控制信息中,优先级较高的上行控制信息可以在受到较少干扰的情况下得到传输,从而保证优先级较高的上行控制信息的解调性能。
本发明实施例提供了一种上行控制信息的传输方法,当出现至少两个对应不同长度的时域资源的上行控制信息且其对应的时域资源有重叠时,仅传输其中一个上行控制信息的部分或全部,或者通过复用的方法传输两个上行控制信息中每个上行控制信息的部分或全部,可以保证优先级较高的上行控制信息得到传输,或保证优先级较高的上行控制信息的解调性能。
需要说明的是,现有的PUCCH格式都是基于1ms TTI的。如果上行引入短TTI的传输,相应的,需要新的支持短TTI传输的上行控制信道,例如支持TTI长度小于1ms的PUCCH的信道结构或新的PUCCH格式。本发明实施例提供了一种新的PUCCH信道结构或新的PUCCH格式,可以使PUCCH可以在上行短TTI上传输。为便于和现有技术中的PUCCH格式区别,本发明实施例中,新的PUCCH格式对应的时域资源称为预设资源。
实施例2
图9所示为本发明实施例的一种上行控制信息的传输方法,如图9所示,所述方法包括:
步骤901,用户设备确定第一上行控制信息。
其中,第一上行控制信息对应的时域资源的长度小于1毫秒,第一上行控制信息对应的时域资源包括M个预设时域资源,M为大于或等于1的整数。
其中,M个预设时域资源中的每个预设时域资源对应的长度小于6个符号。
其中,第一上行控制信息包括混合自动重传请求信息、信道状态信息、调度请求信息中的至少一种。
需要说明的是,信道状态信息包括CQI信息,PMI信息,RI信息中的至少一种。
在具体实施步骤901的过程中,可选的,第一上行控制信息对应的时域资源的长度为第一上行控制信息对应的PUCCH的长度。可选的,第一上行控制信息对应的时域资源的长度为0.5ms或0.25ms或4个符号或3个符号或2个符号或1个符号。可选的, 第一上行控制信息对应的时域资源的长度为第一传输时间间隔TTI时长。进一步可选的,第一TTI时长小于1ms,例如,第一TTI时长为0.5ms或0.25ms或4个符号或3个符号或2个符号或1个符号。
在具体实施步骤901的过程中,可选的,第一上行控制信息对应的资源为第一上行控制信息对应的PUCCH信道资源。
在具体实施步骤901的过程中,可选的,基站为用户设备分配第一上行控制信息对应的时域资源。进一步可选的,基站通过RRC信令或MAC信令或物理层信令等方式将第一上行控制信息对应的时域资源的资源分配信息通知给用户设备。进一步可选的,该RRC信令或MAC信令或物理层信令可以承载在本载波上,也可以承载在非本载波上。可选的,还可以通过预定义的方式使用户设备确定第一上行控制信息对应的时域资源。
在具体实施步骤901的过程中,可选的,用户设备接收基站发送的指示信息,指示信息包括第一上行控制信息对应的时域资源的资源分配信息。需要说明的是,上行控制信息对应的时域资源的资源分配信息可以是上行控制信息对应的时域资源的长度的指示信息,可以是上行控制信息对应的PUCCH的TTI长度的指示信息,可以是上行控制信息对应的PUCCH信道资源的指示信息,也可以是包括时域资源指示,和/或频域资源指示,和/或空域资源指示,和/或码资源指示的上行控制信息对应的资源分配信息。
需要说明的是,步骤901中,第一上行控制信息对应的时域资源是预分配给用户设备的用于传输第一上行控制信息的时域资源,该第一上行控制信息实际传输时使用的时域资源不一定是该预分配的第一上行控制信息对应的全部的时域资源。
在具体实施步骤901的过程中,可选的,M个预设时域资源在时域上是连续的。可选的,M个预设时域资源在时域上是非连续的。
在具体实施步骤901的过程中,可选的,M个预设时域资源中的每个预设时域资源对应的长度为1个符号。以图10为例具体说明,如图10所示,每个预设时域资源的长度为1个符号,第一上行控制信息对应的时域资源的长度为0.5ms时,第一上行控制信息对应的时域资源包括7个预设时域资源;第一上行控制信息对应的时域资源的长度分别为4个符号、3个符号、2个符号、1个符号时,第一上行控制信息对应的时域资源分别包括4个预设时域资源、3个预设时域资源、2个预设时域资源、1个预设时域资源。
在具体实施步骤901的过程中,可选的,M个预设时域资源中的每个预设时域资源对应的长度为2个符号。以图11为例具体说明,如图11所示,每个预设时域资源的长度为2个符号,第一上行控制信息对应的时域资源的长度为0.5ms时,第一上行控制信息对应的时域资源包括3个预设时域资源;第一上行控制信息对应的时域资源的长度分别为4个符号、3个符号、2个符号时,第一上行控制信息对应的时域资源分别包括2个预设时域资源、1个预设时域资源、1个预设时域资源。
在具体实施步骤901的过程中,可选的,M个预设时域资源中的每个预设时域资源对应的长度为3个符号。以图12为例具体说明,如图12所示,每个预设时域资源的长度为3个符号,第一上行控制信息对应的时域资源的长度为0.5ms时,第一上行控制信息对应的时域资源包括2个预设时域资源;第一上行控制信息对应的时域资源的长度分别为4个符号和3个符号时,第一上行控制信息对应的时域资源均包括1个预设时域资源。
需要说明的是,第一上行控制信息对应的时域资源除了包括整数个预设时域资源外,还可以包括长度小于预设时域资源的时域资源。例如在图11所示的情况中,预设时域资源的长度为2个符号,第一上行控制信息对应的时域资源的长度为3个符号时,第一上行控制信息对应的时域资源除包括1个预设时域资源外还包括1个符号的时域资源。又例如在图12所示的情况中,预设时域资源的长度为3个符号,第一上行控制信息对应的时域资源的长度为4个符号时,第一上行控制信息对应的时域资源除包括1个预设时域资源外还包括1个符号的时域资源。可选的,该长度小于预设时域资源的时域资源可以用于重复传输预设时域资源的部分或全部内容。可选的,该长度小于预设时域资源的时域资源可以用于传输参考信号。由于参考信号放在前面可以使接收侧尽早做信道估计,减少接收端的处理时延,因此进一步可选的,该参考信号在发送预设时域资源之前发送。如图11或图12所示,该长度小于预设时域资源的时域资源用于传输参考信号,该参考信号放在一个时隙里的第一个符号上。
步骤902,用户设备在M个预设时域资源中的每个预设时域资源上发送第一上行控制信息中的全部信息。
需要说明的是,第一上行控制信息对应的时域资源可以是PUCCH对应的时域资源。本实施例的数据传输方法,可以认为是一种PUCCH的信道结构方案,其中,该种PUCCH信道资源对应的PUCCH格式在M个预设时域资源中的每个预设时域资源上发送。
需要说明的是,M个预设时域资源中的每个预设时域资源携带第一上行控制信息中的全部信息,其中每个预设时域资源传输该第一上行控制信息的形式可以相同,例如M个预设时域资源重复发送,也可以不同,例如M个预设时域资源中不同的预设时域资源使用不同的扰码。可选的,M个预设时域资源中的每个预设时域资源对应的频域资源可以相同,也可以不同,例如M个预设时域资源中的每个预设时域资源对应的频域资源可以根据预定义的或基站通知的跳频图案进行跳频传输。可选的,M个预设时域资源中的每个预设时域资源对应的码资源可以相同,也可以不同,例如M个预设时域资源中的每个预设时域资源对应的码资源可以根据预定义的或基站通知的码资源进行传输。
需要说明的是,由于M个预设时域资源中的每个预设时域资源携带相同的上行控制信息内容,为了使接收端可以对每个预设时域资源独立解调,需要发送参考信号,该参考信号可以承载在M个预设时域资源中的每个预设时域资源上,也可以承载在除M个预设时域资源外的时域资源上。
在具体实施步骤902的过程中,可选的,M个预设时域资源中的每个预设时域资源上至少发送参考信号。考虑到用户设备上行传输的单载波特性,可选的,M个预设时域资源中的每个预设时域资源上至少发送一个符号的参考信号。为了减少接收端的解调时延,可选的,M个预设时域资源中的每个预设时域资源上至少第一个符号用于发送参考信号。可选的,对于预设时域资源的长度为1个符号的情况,该符号用于发送参考信号,上行控制信息内容可以携带在该参考信号上,例如用不同的码资源来区分发送的上行控制信息的内容。
由于TTI缩短,在用户设备的上行传输中,也可以破坏单载波特性,在具体实施步骤902的过程中,可选的,参考信号和上行控制信息的内容频分复用。例如对于预设时域资源的长度为1个符号的情况,该符号上同时发送参考信号和上行控制信息的内容,其中,参考信号和上行控制信息的内容占用不同的频率资源。
本发明实施例还可以应用于下行传输和其对应的上行传输的TTI长度不相等的场景。下面以图4中的上行载波和下行载波2为例具体说明。假设上行载波的一个TTI的时长等于N个下行载波2的TTI的时长,预设时域资源的长度和下行载波2的TTI的长度相等。即,假设下行载波2的TTI的时长为L2,则上行载波的TTI的时长L1=N*L2,一个上行控制信息对应的时域资源包括N个预设时域资源。图4所示的实施例中,N=2。 如图4所示,按HARQ时序,下行载波2的第k个TTI上的数据对应的HARQ-ACK信息,会在下行载波2的第k+4个TTI对应的上行载波的TTI上反馈,即4301上的HARQ-ACK信息会在4203上进行反馈,4305上的HARQ-ACK信息会在4205的前半部分上进行反馈,4306上的HARQ-ACK信息会在4205的后半部分上进行反馈。如果用户设备没有被连续调度多个下行TTI,即假设用户设备在4301上被调度,那么用户设备可以在4203指示的包括2个预设时域资源的TTI上传输4301对应的上行控制信息。为了减少时延,基站可以只解调第1个预设时域资源来确定上行控制信息;为了提高解调性能,基站也可以联合2个预设时域资源解调来确定上行控制信息。如果用户设备被连续调度多个下行TTI,如图所示,假设用户设备在4305和4306上被调度,那么用户设备可以在4205指示的包括2个预设时域资源的TTI中的第1个预设时域资源上传输4305对应的上行控制信息,在4205指示的包括2个预设时域资源的TTI中的第2个预设时域资源上传输4306对应的上行控制信息。相应地,基站在4205指示的包括2个预设时域资源的TTI中的第1个预设时域资源上解调4305对应的上行控制信息,在4205指示的包括2个预设时域资源的TTI中的第2个预设时域资源上解调4306对应的上行控制信息。
本发明实施例中,所述方法还可以包括:
用户设备确定第二上行控制信息,第二上行控制信息包括混合自动重传请求信息、信道状态信息、调度请求信息中的至少一种;
用户设备在第二上行控制信息对应的时域资源上发送第二上行控制信息;
第一上行控制信息对应的时域资源的长度小于第二上行控制信息对应的时域资源的长度。
需要说明的是,这里不限定用户设备确定第一上行控制信息和第二上行控制信息的先后顺序。
可选的,第二上行控制信息对应的时域资源的长度为第二上行控制信息对应的PUCCH的长度。可选的,第二上行控制信息对应的时域资源的长度为1ms或0.5ms或0.25ms或4个符号或3个符号或2个符号。
可选的,当第二上行控制信息对应的时域资源的长度为1ms时,第二上行控制信息选择长度为1ms的PUCCH格式中的至少一种进行传输。
可选的,当第二上行控制信息对应的时域资源的长度小于或等于1ms时,第二上 行控制信息对应的时域资源包括含N个预设时域资源,N为大于1的整数。需要说明的是,用户设备确定第二上行控制信息以及在第二上行控制信息对应的时域资源上发送第二上行控制信息的方法和步骤901,902中描述的用户设备确定第一上行控制信息以及在第一上行控制信息对应的时域资源上发送第一上行控制信息的方法相同,此处不再赘述。
本发明实施例中,M个预设时域资源中的每个预设时域资源携带相同的上行控制信息内容,接收端可以联合M个预设时域资源解调提高解调性能,也可以对每个预设时域资源独立解调。因此,结合本发明实施例中的PUCCH的信道结构,当出现两个对应不同长度的时域资源的上行控制信息且其对应的时域资源有重叠时,上行控制信息在其预分配的上行控制信息对应的时域资源中的部分时域资源上传输,仍然可能被正确解调。所以本发明实施例中,所述方法还可以包括:
当第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠,用户设备在重叠的时域资源上传输第三上行控制信息,第三上行控制信息包括第四上行控制信息和第五上行控制信息中的至少一种,
其中,该第四上行控制信息包括该第一上行控制信息中的部分信息或该第一上行控制信息中的全部信息,该第五上行控制信息包括该第二上行控制信息中的部分信息或该第二上行控制信息中的全部信息。
具体来说,第三上行控制信息可以包括以下八种情况:
第一上行控制信息中的部分信息;
第二上行控制信息中的部分信息;
第一上行控制信息中的全部信息;
第二上行控制信息中的全部信息;
第一上行控制信息中的部分信息和第二上行控制信息中的部分信息;
第一上行控制信息中的部分信息和第二上行控制信息中的全部信息;
第一上行控制信息中的全部信息和第二上行控制信息中的部分信息;
第一上行控制信息中的全部信息和第二上行控制信息中的全部信息。
本发明实施例中提出的上行控制信息传输的信道结构或方法还可以和本发明实施例1中传输上行控制信息的方法结合使用,具体实施方法可以参见本发明实施例1的实施方法,重复之处不再赘述。
本发明实施例中提出的上行控制信息传输的信道结构或方法可以使上行控制信息在其预分配的上行控制信息对应的时域资源中的部分时域资源上传输时,仍然可能被正确解调。进一步的,当出现多个对应不同长度的时域资源的上行控制信息且其对应的时域资源有重叠时,本发明实施例中提出的方法可以使多个上行控制信息都可能被传输和正确解调。
本发明上述实施例1的上行控制信息的传输方法应用于用户设备,用户设备确定第一上行控制信息以及第二上行控制信息,当所述第一上行控制信息对应的时域资源与所述第二上行控制信息对应的时域资源有重叠,用户设备在重叠的时域资源上传输第三上行控制信息,本发明如上的实施例具体说明了第三上行控制信息的多种应用实例。用户设备发送第三上行控制信息至基站,基站接收第三上行控制信息。
实施例3
本发明实施例还公开了一种上行控制信息的传输方法,应用于基站,图13所示为本发明实施例的上行控制信息传输方法的流程图,如图13所示,所述方法包括:
步骤1301,基站在第一上行控制信息对应的时域资源接收第一上行控制信息,在第二上行控制信息对应的时域资源接收第二上行控制信息。
第一上行控制信息对应的时域资源的长度小于第二上行控制信息对应的时域资源的长度,第一上行控制信息或第二上行控制信息包括混合自动重传请求信息、信道状态信息、调度请求信息中的至少一种;
步骤1302,当第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源有重叠,基站在重叠的时域资源上接收第三上行控制信息。
第三上行控制信息包括第四上行控制信息和第五上行控制信息中的至少一种;
其中,该第四上行控制信息包括该第一上行控制信息中的部分信息或该第一上行控制信息中的全部信息,该第五上行控制信息包括该第二上行控制信息中的部分信息或该第二上行控制信息中的全部信息。

如实施例1所示,本实施例中也根据第三上行控制信息的内容的不同,分为三种情形。
情形一:第三上行控制信息包括第四上行控制信息,即第三上行控制信息包括第一上行控制信息的部分或全部。
即,基站在第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源中重叠的时域资源上只接收第一上行控制信息的部分或全部。
以图7为例具体说明情形一。如图7所示,假设第一上行控制信息对应的时域资源的长度为2个符号,具体对应符号0和符号1,用于传输第一上行控制信息;第二上行控制信息对应的时域资源的长度为4个符号,具体对应符号0,1,2,3,用于传输第二上行控制信息。第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源在符号0和符号1上有重叠。其中,符号0和符号1用7209表示,符号2和符号3用7210表示。在图7所示的例子中,第一上行控制信息对应的资源与第二上行控制信息对应的资源在频域上没有重叠。其中,用户设备在第一上行控制信息对应的时域资源与第二上行控制信息对应的时域资源中重叠的时域资源上,例如图7中7209表示的符号上发送第一上行控制信息的部分或全部。

可选的,基站在重叠的时域资源上传输第二上行控制信息的部分或全部可以为基站在重叠的时域资源中第一上行控制信息对应的资源上接收第二上行控制信息的部分或全部。例如基站在图7中72091表示的资源上接收第二上行控制信息的部分或全部。
可选的,基站在重叠的时域资源上接收第二上行控制信息的部分或全部可以为基站在重叠的时域资源中第二上行控制信息对应的资源上接收第二上行控制信息的部分或全部。例如基站在图7中72092表示的资源上接收第二上行控制信息的部分或全部。
情形三:第三上行控制信息包括第四上行控制信息和第五上行控制信息。即第三上行控制信息包括第一上行控制信息的部分或全部,以及第二上行控制信息的部分或全部。
