技术领域
本公开涉及通信技术领域,特别是指一种上行控制信道的发送方法、接收方法、装置、终端及基站。
背景技术
随着移动通信业务需求的发展变化,ITU(International Telecommunication Union,国际电信联盟)和3GPP等组织都开始研究新的无线通信系统(例如5G新空口(5G NR,5Generation New RAT))。新的无线通信系统中定义了新的帧结构,支持不同的基带参数(numerology,包括如子载波间隔等参数)。针对不同的基带参数,定义了一个子帧的长度总是1ms,一个子帧包含A个时隙(slot),对应不同的基带参数,A的个数可能不同,用于满足一个子帧的长度为1ms。针对不同的基带参数,一个时隙中可以包含7或14个符号(OFDM(正交频分复用技术)符号或DFT-S-OFDM(离散傅里叶变换扩频的正交频分复用多址接入技术)符号等)。例如子载波间隔为30kHz时,假设约定或配置一个slot包含7个符号,则为了满足一个子帧长度为1ms,一个子帧中需包含4个slot,假设约定或配置一个slot包含14个符号,则为了满足一个子帧长度为1ms,一个子帧中需包含2个slot。一个时隙可以有多种时隙结构,不同的结构对应一个时隙中不同的上下行资源划分,例如一个时隙中的多个符号可以都用于下行传输,即下行传输时隙(DL only slot),也可以都用于上行传输,即上行传输时隙(UL only slot),还可以部分用于上行传输、部分用于下行传输,即上下行传输时隙(DL+UL slot)。时隙结构可以半静态通过无线资源控制RRC信令通知给终端,也可以通过组播公共信令动态通知给终端,实现动态改变时隙结构。
由于一个时隙中包含的上行符号个数可能发生变化,5G NR系统中定义了长PUCCH(Physical Uplink Control Channel,物理上行链路控制信道)和短PUCCH两类PUCCH。其中长PUCCH可以为4到14个符号,短PUCCH可以为1或2个符号。为了提高上行覆盖,上行控制信息(UCI)在长PUCCH中传输时,还可以在多个时隙中进行重复传输。由于不同时隙的上行区域大小可能不同,目前如何在多个时隙中进行长PUCCH传输还没有明确方案。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,本公开一些实施例提供一种上行控制信道的发送方法,包括:
步骤11,确定发送待反馈的上行控制信息的多个目标时隙,其中,所述待反馈的上行控制信息在所述目标时隙中通过上行控制信道进行发送。
本步骤中,上行控制信道的发送方法一般应用于终端侧,即终端确定待反馈的上行控制信息UCI,并确定待反馈的UCI在多个目标时隙中通过上行控制信道传输。
步骤12,获取所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;其中,每个所述目标时隙中的上行控制信道的传输长度或格式相同。
本步骤中,不同的目标时隙中承载待反馈的UCI的上行控制信道的传输长度或格式是相同的,例如,目标时隙1中承载待反馈的UCI的上行控制信 道的传输长度为7个符号,则其他目标时隙中(如目标时隙2、3等)承载待反馈的UCI的上行控制信道的传输长度均为7个符号。
步骤13,按照确定的所述上行控制信道的传输长度或格式,在每个所述目标时隙中发送承载所述待反馈的上行控制信息的上行控制信道。
本步骤中,一种传输长度或格式对应了一种传输结构,即按照对应的传输结构在每个目标时隙中发送承载所述待反馈的UCI的上行控制信道。
具体的,本公开的一些实施例中,步骤11包括:
根据预先定义的多个目标时隙的信息,确定发送待反馈的上行控制信息的多个目标时隙;预先定义可以是终端和基站均遵守的某一标准的定义;或者,
根据高层信令配置的多个目标时隙的信息,确定发送待反馈的上行控制信息的多个目标时隙;或者,
接收预设下行控制信道发送的多个目标时隙的信息,确定发送待反馈的上行控制信息的多个目标时隙;其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道。
具体的,多个目标时隙的信息至少包括:多个目标时隙的数量以及多个目标时隙的标识;例如,4个目标时隙,目标时隙1、目标时隙2、目标时隙3以及目标时隙4。
进一步的,本公开的一些实施例中步骤12包括:
根据预先定义获取所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;或者,
根据高层信令的配置确定所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;或者,
根据预设下行控制信道中的指示域确定所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息 反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道;或者,
根据所述多个目标时隙中的至少一个目标时隙中的上行区域的大小或至少一个目标时隙中用于传输上行控制信道的上行区域的大小,确定所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;例如,根据多个目标时隙中的第一个目标时隙的上行区域的大小来确定上行控制信道的传输长度或格式;再例如,根据多个目标时隙中的所有目标时隙的上行区域的大小的平均值来确定上行控制信道的传输长度或格式;又例如,根据多个目标时隙中上行区域最小的目标时隙的上行区域的大小来确定上行控制信道的传输长度或格式。
需要说明的是,上行控制信道的传输长度和格式可以是一一对应,例如一个传输长度对应唯一一种格式,或者一种格式对应唯一一个传输长度;也可以同一个传输长度对应多种格式,则确定了格式就可以确定传输长度;还可以同一格式对应多个传输长度,则确定了传输长度就可以确定格式。
进一步的,本公开的一些实施例中,步骤13包括:
根据确定的所述上行控制信道的传输长度或格式,确定所述上行控制信道内上行控制信息和参考信号的传输结构;
根据所述传输结构,在每个所述目标时隙中发送承载所述待反馈的上行控制信息和参考信号的所述上行控制信道。
本公开的一些实施例中,一个传输长度或格式对应一种上行控制信息UCI和参考信号RS的传输结构,即根据传输长度或格式可以确定上行控制信道进行UCI和RS映射时的映射结构,即上行控制信道所占用的多个符号中哪些符号用于传输UCI,哪些符号用于传输RS。例如,传输长度为7个符号,格式为x1,则对应的UCI和RS结构为UURRRUU(或为URUURRU),其中U表示7个符号中传输UCI的符号位置,R表示7个符号中传输RS的符号位置。又例如,传输长度为4个符号,格式为x2,则对应的UCI和RS结构为URRU(或RURU)。综上,确定了传输长度或格式就可以确定对应的UCI和RS结构,就可以按照该结构在上行控制信道中传输UCI和RS。
需要说明的是,上述传输结构仅为本公开的一些实施例,还可以有其他结构,针对不同传输长度以及是否存在符号之间的跳频,也可以有不同的UCI和RS结构,不是本公开所关注的内容,在此不进行详细描述。
本公开的一些实施例中,由于多个目标时隙中可能包含相同的上行区域或用于传输上行控制信道的上行区域,也可能包含不同的上行区域或用于传输上行控制信道的上行区域,则针对相同传输长度或格式的上行控制信道,其上行控制信道在多个目标时隙中的位置可能相同也可能不同。故为了更准确的确定承载待反馈的UCI的上行控制信道的位置,本公开一些实施例提供的上行控制信道的发送方法中还需进一步确定多个目标时隙中所述上行控制信道的起始位置和/或截止位置。
具体的,确定多个目标时隙中所述上行控制信道的起始位置和/或截止位置的方法还包括:
接收预设下行控制信道发送的一个或多个目标时隙中所述上行控制信道的起始位置和/或截止位置,其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道;和/或,
根据预先约定的规则确定一个或多个目标时隙中所述上行控制信道的起始位置和/或截止位置。
具体的,若多个目标时隙中的每个目标时隙中包含相同大小的上行区域或用于传输上行控制信道的上行区域,此时:
所述上行控制信道在每个目标时隙的上行区域(或用于传输上行控制信道的上行区域)中的起始位置和/或截止位置是相同的,可以是预先约定的位置,也可以是根据预设下行控制信道中的指示域确定的。
若多个目标时隙中的至少两个目标时隙包含不同大小的上行区域或用于传输上行控制信道的上行区域,此时:
可通过预设下行控制信道的指示域来确定每个上行控制信道的起始位置和/或截止位置;其中,多个目标时隙中的每个目标时隙都对应一个独立的指 示。
或者在多个目标时隙中的第一个目标时隙中的上行控制信道的起始位置和/或截止位置是根据预设下行控制信道中的指示域确定的;其中,所述预设下行控制信道中仅指示一个起始位置和/或截止位置;而在多个目标时隙中的其他目标时隙中,其上行控制信道的起始位置和/或截止位置是根据预先约定的规则确定的,例如预先约定占满所述目标子帧中的上行区域或用于传输所述上行控制信道的上行区域,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的第A个符号开始,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的倒数第B个符号截止等。
再或者,在多个目标时隙中的每个目标时隙中,其上行控制信道的起始位置和/或截止位置均是根据预先预定的规则确定的。例如,预先约定占满所述目标子帧中的上行区域或用于传输所述上行控制信道的上行区域,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的第A个符号开始,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的倒数第B个符号截止等。
需要说明的是:
如果没有获得指示目标时隙的结构的信息(即不能确定每个目标时隙中的上行区域或用于传输上行控制信道的上行区域),或者如果目标时隙中的上行区域的大小(或用于传上行控制信道的上行区域的大小)小于确定的传输长度或确定的格式对应的传输长度,或根据预设下行控制信道的指示或根据预先约定的规则确定的起始位置和/或截止位置与所述目标时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)不吻合(例如指示的起始和/或截止位置不在这个范围内),则终端可以跳过这个目标时隙,在下一个目标时隙中继续传输(该目标时隙的个数可以计入N个目标时隙,也可以不计入,N为预先确定的传输UCI的目标时隙的个数)。
进一步,在上述情况中,如果终端接收到预设下行控制信道,且预设下行控制信道指示上行控制信道的起始位置和/或截止位置,则终端也可以根据指示的起始位置和/或截止位置,以及确定好的传输长度或确定好的格式对应 的传输长度,在该目标时隙中进行上行控制信道传输(即不管该目标时隙中的上下行资源分配,不管该目标时隙中的上行区域或上行区域中用于传输上行控制信道的区域的大小,终端总是按照指示的位置进行传输);或者,在上述情况中,终端总是根据预先约定的规则确定的该目标时隙中的起始位置和/或截止位置,以及确定好的传输长度或确定好的格式对应的传输长度,在该目标时隙中进行上行控制信道传输(即不管该目标时隙中的上下行资源分配,不管该目标时隙中的上行区域或上行区域中用于传输上行控制信道的区域的大小,终端总是按照指示的位置进行传输)。

或者,若所述待反馈的上行控制信息的大小大于所述第一预设值,根据所述上行控制信道中承载所述上行控制信息的符号个数以及所述目标时隙的个数对所述待反馈的上行控制信息进行信道编码和速率匹配得到编码后的第二比特序列,在每个所述目标时隙中发送承载与目标时隙对应的第二比特序列的子比特序列的上行控制信道;即当待反馈的UCI大于2比特时,对待反馈的UCI基于对应传输长度或格式的上行控制信道中承载UCI的符号个数以 及目标时隙的个数进行信道编码和速率匹配,得到编码后的第二比特序列,并在第二比特序列中取与目标时隙对应的子比特序列在该目标时隙中进行传输。例如,第二比特序列为111000111,目标时隙的个数为3个,分别为目标时隙1、目标时隙2以及目标时隙3,与目标时隙1对应的子比特序列为111,与目标时隙2对应的子比特序列为000,与目标时隙3对应的子比特序列为111;则在目标时隙1中传输承载子比特序列为111的上行控制信道,在目标时隙2中传输承载子比特序列为000的上行控制信道,在目标时隙3中传输承载子比特序列为111的上行控制信道。

综上,本公开一些实施例提供的终端中,当终端需要在多个目标时隙中传输上行控制信道时,终端在多个目标时隙中按照相同的上行控制信道的传输长度或格式进行上行控制信道的传输,实现了在多个时隙中进行上行控制信道传输的目的。
需要说明的是,本公开一些实施例提供的终端是与上述上行控制信道的发送方法相对应的终端,则上述上行控制信道的发送方法的所有实施例均适用于该终端,且均能达到相同或相似的有益效果。
为了更好的实现上述目的,本公开一些实施例还提供一种计算机可读存储介质,其上存储有计算机程序,该程序被处理器执行时实现以下步骤:

为了更好的对上行控制信道的传输方法进行描述,如图4所示,本公开一些实施例还提供一种上行控制信道的接收方法,应用于基站侧,包括:
步骤41,确定发送待反馈的上行控制信息的多个目标时隙,其中,所述待反馈的上行控制信息在所述目标时隙中通过上行控制信道进行发送。
本步骤中,上行控制信道的发送方法一般应用于终端侧,即终端确定待反馈的上行控制信息UCI,并确定待反馈的UCI在多个目标时隙中通过上行控制信道传输。
步骤42,获取所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;其中,每个所述目标时隙中的上行控制信道的传 输长度或格式相同。
本步骤中,不同的目标时隙中承载待反馈的UCI的上行控制信道的传输长度或格式是相同的,例如,目标时隙1中承载待反馈的UCI的上行控制信道的传输长度为7个符号,则其他目标时隙中(如目标时隙2、3等)承载待反馈的UCI的上行控制信道的传输长度均为7个符号。
步骤43,按照确定的所述上行控制信道的传输长度或格式,在每个所述目标时隙中接收承载所述待反馈的上行控制信息的上行控制信道。
本步骤中,一种传输长度或格式对应了一种传输结构,即按照对应的传输结构在每个目标时隙中发送承载所述待反馈的UCI的上行控制信道。
具体的,本公开的一些实施例中步骤41包括:
根据预先定义的多个目标时隙的信息,确定发送待反馈的上行控制信息的多个目标时隙;其中,预先定义可以是终端和基站均遵守的某一标准的定义。具体的,多个目标时隙的信息至少包括:多个目标时隙的数量以及多个目标时隙的标识;例如,4个目标时隙,目标时隙1、目标时隙2、目标时隙3以及目标时隙4。
进一步的,本公开的一些实施例中,步骤41之后,所述方法包括:
将所述多个目标时隙的信息通过高层信令或者预设下行控制信道发送给终端;其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道。
具体的,本公开的一些实施例中步骤42包括:
根据预先定义获取所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;或者,
根据所述多个目标时隙中的至少一个目标时隙中的上行区域的大小或至少一个目标时隙中用于传输上行控制信道的上行区域的大小,确定所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式;例如,根据多个目标时隙中的第一个目标时隙的上行区域的大小来确定上行控制信道的传输长度或格式;再例如,根据多个目标时隙中的所有目标时隙 的上行区域的大小的平均值来确定上行控制信道的传输长度或格式;又例如,根据多个目标时隙中上行区域最小的目标时隙的上行区域的大小来确定上行控制信道的传输长度或格式。
需要说明的是,上行控制信道的传输长度和格式可以是一一对应,例如一个传输长度对应唯一一种格式,或者一种格式对应唯一一个传输长度;也可以同一个传输长度对应多种格式,则确定了格式就可以确定传输长度;还可以同一格式对应多个传输长度,则确定了传输长度就可以确定格式。
进一步的,本公开的一些实施例中,步骤42之后,所述方法还包括:
将所述目标时隙中承载所述待反馈的上行控制信息的上行控制信道的传输长度或格式通过高层信令或者预设下行控制信道发送给终端;其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道。
具体的,本公开的一些实施例中步骤43包括:
根据确定的所述上行控制信道的传输长度或格式,确定所述上行控制信道内上行控制信息和参考信号的传输结构;
根据所述传输结构,在每个所述目标时隙中接收承载所述待反馈的上行控制信息和参考信号的所述上行控制信道。
本公开的一些实施例中,一个传输长度或格式对应一种上行控制信息UCI和参考信号RS的传输结构,即根据传输长度或格式可以确定上行控制信道进行UCI和RS映射时的映射结构,即上行控制信道所占用的多个符号中哪些符号用于传输UCI,哪些符号用于传输RS。例如,传输长度为7个符号,格式为x1,则对应的UCI和RS结构为UURRRUU(或为URUURRU),其中U表示7个符号中传输UCI的符号位置,R表示7个符号中传输RS的符号位置。又例如,传输长度为4个符号,格式为x2,则对应的UCI和RS结构为URRU(或RURU)。综上,确定了传输长度或格式就可以确定对应的UCI和RS结构,就可以按照该结构在上行控制信道中传输UCI和RS。
需要说明的是,上述传输结构仅为本公开的一些实施例,还可以有其他 结构,针对不同传输长度以及是否存在符号之间的跳频,也可以有不同的UCI和RS结构,不是本公开所关注的内容,在此不进行详细描述。
本公开的一些实施例中,由于多个目标时隙中可能包含相同的上行区域或用于传输上行控制信道的上行区域,也可能包含不同的上行区域或用于传输上行控制信道的上行区域,则针对相同传输长度或格式的上行控制信道,其上行控制信道在多个目标时隙中的位置可能相同也可能不同。故为了更准确的确定承载待反馈的UCI的上行控制信道的位置,本公开一些实施例提供的上行控制信道的发送方法中还需进一步确定多个目标时隙中所述上行控制信道的起始位置和/或截止位置。
具体的,确定多个目标时隙中所述上行控制信道的起始位置和/或截止位置的方法还包括:
根据预先约定的规则确定一个或多个目标时隙中所述上行控制信道的起始位置和/或截止位置。
且所述方法还包括:
通过预设下行控制信道将确定的一个或多个目标时隙中所述上行控制信道的起始位置和/或截止位置发送给终端,其中,所述预设下行控制信道为如下信道中的至少一种:在所述上行控制信道中进行上行控制信息反馈的下行共享信道所对应的下行控制信道、在所述上行控制信道中进行上行控制信息反馈的指示下行半持续调度资源释放的下行控制信道以及用于指示目标时隙的时隙结构的组播下行控制信道。
具体的,若多个目标时隙中的每个目标时隙中包含相同大小的上行区域或用于传输上行控制信道的上行区域,此时:
所述上行控制信道在每个目标时隙的上行区域(或用于传输上行控制信道的上行区域)中的起始位置和/或截止位置是相同的,可以是预先约定的位置,也可以是根据预设下行控制信道中的指示域确定的。
若多个目标时隙中的至少两个目标时隙包含不同大小的上行区域或用于传输上行控制信道的上行区域,此时:
可通过预设下行控制信道的指示域来确定每个上行控制信道的起始位置和/或截止位置;其中,多个目标时隙中的每个目标时隙都对应一个独立的指 示。
或者在多个目标时隙中的第一个目标时隙中的上行控制信道的起始位置和/或截止位置是根据预设下行控制信道中的指示域确定的;其中,所述预设下行控制信道中仅指示一个起始位置和/或截止位置;而在多个目标时隙中的其他目标时隙中,其上行控制信道的起始位置和/或截止位置是根据预先约定的规则确定的,例如预先约定占满所述目标子帧中的上行区域或用于传输所述上行控制信道的上行区域,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的第A个符号开始,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的倒数第B个符号截止等。
再或者,在多个目标时隙中的每个目标时隙中,其上行控制信道的起始位置和/或截止位置均是根据预先预定的规则确定的。例如,预先约定占满所述目标子帧中的上行区域或用于传输所述上行控制信道的上行区域,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的第A个符号开始,或者预先约定从目标子帧中的上行区域或用于传输所述上行控制信道的上行区域中的倒数第B个符号截止等。
需要说明的是:
如果没有获得指示目标时隙的结构的信息(即不能确定每个目标时隙中的上行区域或用于传输上行控制信道的上行区域),或者如果目标时隙中的上行区域的大小(或用于传上行控制信道的上行区域的大小)小于确定的传输长度或确定的格式对应的传输长度,或根据预设下行控制信道的指示或根据预先约定的规则确定的起始位置和/或截止位置与所述目标时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)不吻合(例如指示的起始和/或截止位置不在这个范围内),则终端可以跳过这个目标时隙,在下一个目标时隙中继续传输(该目标时隙的个数可以计入N个目标时隙,也可以不计入,N为预先确定的传输UCI的目标时隙的个数)。
进一步,在上述情况中,如果终端接收到预设下行控制信道,且预设下行控制信道指示上行控制信道的起始位置和/或截止位置,则终端也可以根据指示的起始位置和/或截止位置,以及确定好的传输长度或确定好的格式对应 的传输长度,在该目标时隙中进行上行控制信道传输(即不管该目标时隙中的上下行资源分配,不管该目标时隙中的上行区域或上行区域中用于传输上行控制信道的区域的大小,终端总是按照指示的位置进行传输);或者,在上述情况中,终端总是根据预先约定的规则确定的该目标时隙中的起始位置和/或截止位置,以及确定好的传输长度或确定好的格式对应的传输长度,在该目标时隙中进行上行控制信道传输(即不管该目标时隙中的上下行资源分配,不管该目标时隙中的上行区域或上行区域中用于传输上行控制信道的区域的大小,终端总是按照指示的位置进行传输)。
具体的,本公开的一些实施例中步骤43包括:
若所述待反馈的上行控制信息的大小小于或者等于第一预设值,在每个所述目标时隙中接收承载调制符号的上行控制信道;其中,所述调制符号为终端对所述待反馈的上行控制信息进行调制得到的调制符号;第一预设值一般可设置为2比特,即当待反馈的UCI为1比特或2比特时,对该1比特或2比特的UCI进行调制后得到1个调制符号,得到的该1个调制符号分别在所述多个目标时隙中的每个目标时隙中,在对应的传输长度或格式的上行控制信道中进行重复传输;
若所述待反馈的上行控制信息的大小大于所述第一预设值,在每个所述目标时隙中接收承载第一比特序列的上行控制信道;即当待反馈的UCI大于2比特时,对待反馈的UCI基于对应传输长度或格式的上行控制信道中承载UCI的符号个数进行信道编码和速率匹配,得到编码后的第一比特序列,并分别在多个目标时隙中的每个目标时隙中进行重复传输。
或者,若所述待反馈的上行控制信息的大小大于所述第一预设值,在每个所述目标时隙中接收承载与目标时隙对应的第二比特序列的子比特序列的上行控制信道;即当待反馈的UCI大于2比特时,对待反馈的UCI基于对应传输长度或格式的上行控制信道中承载UCI的符号个数以及目标时隙的个数进行信道编码和速率匹配,得到编码后的第二比特序列,并在第二比特序列中取与目标时隙对应的子比特序列在该目标时隙中进行传输。例如,第二比特序列为111000111,目标时隙的个数为3个,分别为目标时隙1、目标时隙2以及目标时隙3,与目标时隙1对应的子比特序列为111,与目标时隙2对 应的子比特序列为000,与目标时隙3对应的子比特序列为111;则在目标时隙1中传输承载子比特序列为111的上行控制信道,在目标时隙2中传输承载子比特序列为000的上行控制信道,在目标时隙3中传输承载子比特序列为111的上行控制信道。
其中,所述第一比特序列是终端根据所述上行控制信道中承载所述上行控制信息的符号个数对所述待反馈的上行控制信息进行信道编码和速率匹配后得到的编码后的比特序列;所述第二比特序列是终端根据所述上行控制信道中承载所述上行控制信息的符号个数以及所述目标时隙的个数对所述待反馈的上行控制信息进行信道编码和速率匹配后得到的编码后的比特序列。
更进一步的,本公开的一些实施例中,基站接收到上行控制信道之后,所述方法还包括:
步骤44,从所述上行控制信道中获取所述待反馈的上行控制信息。
具体的,步骤44包括:
若所述待反馈的上行控制信息的大小小于或者等于第一预设值,对在每个所述目标时隙中接收到的调制符号进行合并(可以是调制符号的合并,也可以是比特的合并),并根据合并后的调制符号确定所述待反馈的上行控制信息;
若所述待反馈的上行控制信息的大小大于所述第一预设值,对在每个所述目标时隙中接收到的第一比特序列进行合并,并对合并后的第一比特序列进行译码以确定所述待反馈的上行控制信息,或者,对在每个所述目标时隙中接收到的与第一比特序列对应的调制符号序列进行合并,并基于合并后的调制符号序列得到第一比特序列,对所述第一比特序列进行译码以确定所述待反馈的上行控制信息;即基站将每个目标时隙中接收到的信息进行合并,得到终端发送的UCI。或者,对在每个所述目标时隙中接收到的第二比特序列的子序列进行级联,得到第二比特序列,并对所述第二比特序列进行译码以确定所述待反馈的上行控制信息;即基站将每个目标时隙中接收到的信息级联在一起进行信道译码,得到终端发送的UCI。
综上,本公开一些实施例提供的上行控制信道的接收方法中,当终端需要在多个目标时隙中传输上行控制信道时,基站在多个目标时隙中按照相同 的上行控制信道的传输长度或格式进行上行控制信道的接收,实现了在多个时隙中进行上行控制信道接收的目的。

为了更好的实现上述目的,下面结合附图对本公开一些实施例提供的上行控制信道的发送方法和接收方法进行举例说明:
假设一个时隙包含7个符号(OFDM或SC-FDMA符号),假设一个上行控制信道(PUCCH)约定或配置在2个目标时隙中进行传输,如果是配置的,可以是高层信令预先配置的,例如对于周期性CSI/SR反馈;也可以是下行控制信道配置的,例如对于ACK/NACK反馈,混合自动重传请求HARQ反馈时序可以是前一个时隙中的下行传输的ACK/NACK在后一个时隙中的上行区域开始进行反馈,也可以是当前时隙中的下行传输的ACK/NACK在当前时隙中的上行区域开始进行反馈,HARQ反馈时序关系可以是预先定义的,也可以是高层信令或上述下行控制信道中的相关指示域配置的。
情况1:多个目标时隙中的上行区域相同,如图7所示,时隙i和时隙i+1的结构都为2个符号为下行区域,1个符号为保护间隔GP,4个符号为上行区域。
终端根据周期UCI的反馈周期确定需要在时隙i中进行CSI/SR反馈,并根据预先约定或高层信令的预先配置或根据2个时隙中的至少一个时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)的大小,确定上行控制信道PUCCH的传输长度为4个符号;或者终端根据上述HARQ反馈时序,确定需要在时隙i中进行ACK/NACK反馈,并根据预先约定或高层信令的预先配置或2个时隙中的至少一个时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)的大小,或与上行控制信道对应的下行控制信道中的指示域,确定PUCCH的传输长度为4个符号。
则在时隙i和时隙i+1中的上行区域中,都按照长度为4的PUCCH的UCI和RS结构进行传输,如图7中的PUCCH1和PUCCH2所示;其中,PUCCH在每个时隙中都在上行区域的第一个符号开始传输,当然PUCCH在上行区域的起始位置和/或结束位置还可以是信令通知的,例如对应的下行控制信道通知,则可以实现PUCCH在上行区域的任意部分符号上进行传输,可以仅针对第一个时隙进行通知,也可以对每个时隙都有相应的通知信令,则不同时隙中的传输位置可以不同。
当UCI不超过2比特时,UCI在每个时隙之间重复传输,每一个时隙中,根据确定的同一个传输长度对应的UCI和RS结构进行传输,基站侧则按照同样的传输长度在时隙i和时隙i+1中接收上行控制信道,并将两个时隙中的 UCI进行合并得到最终的UCI;当超过2比特时,可以在每个时隙之间重复传输,即终端侧基于根据传输长度确定的UCI和RS结构中的UCI的传输符号个数进行信道编码和速率匹配,然后在两个时隙中重复传输相同的编码后序列,基站侧则按照同样的传输长度在时隙i和时隙i+1中接收上行控制信道,并将两个时隙中接收到的UCI信息进行合并,得到最终的UCI信息,也可以在两个slot中进行联合编码传输,即终端侧基于两个时隙中根据传输长度确定的UCI和RS结构中UCI的传输符号总数进行信道编码和速率匹配,然后分为两部分分别在两个时隙中传输,基站侧则按照同样的传输长度在时隙i和时隙i+1中接收上行控制信道,并将两个时隙中接收到的UCI信息级联在一起进行信道译码,得到最终的UCI信息。
情况2:多个目标时隙中的上行区域不相同,如图8所示,时隙i的结构为2个符号为下行传输,1个符号为保护间隔GP,4个符号为上行传输,而时隙i+1的结构为全上行,即7个符号都为上行传输;或者如图9所示,时隙i的结构为2个符号为下行传输,1个符号为保护间隔GP,4个符号为上行传输,而时隙i+1的结构为1个符号为下行传输,1个符号为保护间隔GP,5个符号为上行传输。
终端根据周期UCI的反馈周期确定需要在时隙i中进行CSI/SR反馈,并根据预先约定或高层信令的预先配置或2个时隙中的至少一个时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)的大小,确定PUCCH的传输长度为4个符号,或者根据上述HARQ反馈时序,确定需要在时隙i中进行ACK/NACK反馈,并根据预先约定或高层信令的预先配置或2个时隙中的至少一个时隙中的上行区域(或上行区域中用于传输上行控制信道的区域)的大小(例如第一个时隙的上行区域大小,或多个时隙的上行区域中的最小值),或与上行控制信道对应的下行控制信道中的指示域,确定PUCCH的传输长度为4个符号。
则在时隙i和时隙i+1中的上行区域中,都按照长度为4的PUCCH的UCI和RS结构进行传输,如图8中的PUCCH1和PUCCH2所示,或如图9中的PUCCH1和PUCCH2所示;其中,PUCCH在每个时隙中都在UL区域的最后一个符号结束传输,即总是占用上行区域中的最后4个符号传输,当然也可以都在上行 区域的第一个符号开始传输,即总是占用上行区域的前4个符号传输,当然PUCCH在上行区域的起始和/或结束位置还可以是信令通知的,例如对应的下行控制信道通知,则可以实现PUCCH在上行区域的任意部分符号上进行传输,可以仅针对第一个时隙进行通知,也可以对每个时隙都有相应的通知信令,则不同时隙中的传输位置可以不同。
当UCI不超过2比特或超过2比特时的传输方法同上情况1,不再赘述。
需要说明的是,一些实施例中的时隙结构仅为举例,每个时隙中包含14个符号时的工作方式同理;上述PUCCH使用4个符号长度(或4个符号长度对应的格式)传输仅为举例,PUCCH还可以使用其他符号长度传输/格式进行传输,例如4~14中的任意整数长度,工作方式同理,在此一一赘述。
以上所述是本公开的一些实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本公开所述原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本公开的保护范围。
