本申请基于申请号为201711144740.2、申请日为2017年11月17日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及但不限于通信领域。
背景技术
在相关技术中，新一代移动通信***即新空口(New Radio，简称为NR)中***，上行控制信道(Physical Uplink Control CHannel，简称为PUCCH)如何确定自身的序列组还未有定论。具体地，NR***中有一种PUCCH格式，通过一个序列的不同循环移位(Cyclic Shift，简称为CS)来携带用户设备(UE)反馈的ACK信息、NACK信息和参考信号(Reference Signal，简称为RS)信息，关于如何确定PUCCH的序列组还未定论。
在相关技术中，NR***中，码块组(Code Block Group，简称为CBG)重传机制被支持，即UE反馈混合自动重传请求-确认信息(Hybrid Automatic Repeat Request-Acknowledge，简称为HARQ-ACK)时可以按照CBG进行反馈，基站重传未被正确解码的CBG，而不需要重传整个传输块(Transport Block，简称为TB)(一般的，一个TB能包含多个CBG)，这样有利于减少重传的数据量。
进一步地，NR***中也支持，如果UE配置了CBG重传机制，当基站使用回退DCI(fallback DCI，一种DCI格式)为UE调度TB)时，如果UE为该TB反馈HARQ-ACK不和其他HARQ-ACK复用时，UE应该反馈TB级别HARQ-ACK。也就是说在上面的情况下，CBG级别的HARQ-ACK 失效了。
但是，这也带来了另一个问题，如果UE配置了CBG重传机制，基站使用回退下行控制信息(Downlink Control Information，简称为DCI)为UE调度TB，且UE为该TB反馈HARQ-ACK要与其他HARQ-ACK复用，UE如何为该TB形成HARQ-ACK还未定论。
在NR***中，PUCCH的资源分配目前正在讨论，基本可以确定的内容有：
NR的PUCCH在调度单元(例如时隙(slot))内被配置起始符号，以及持续的符号数，以及是否跳频，起始的CS索引等，以确定该PUCCH发送时具体的资源等。例如，一个PUCCH可以被开始从调度单元中某一符号，持续N个符号，并且跳频，起始的CS索引等。PUCCH在调度单元的起始符号是变化的，是通过基站配置的。PUCCH的符号数也是基站配置的，跳频后，每个跳频(英文可以表达为hop)的符号位置也是变化的。相关技术中，在LTE中PUCCH在子帧内的起始位置是固定的，符号数也是固定的，跳频位置也是固定。
在NR***中对于一些PUCCH，它是通过正交序列来携带ACK和/或NACK比特信息的，例如通过一个序列(这个序列本文称为序列组，也有称基序列)的不同CS分别携带ACK信息和NACK，以及RS信息，对于PUCCH等信道或信号如何确定其使用的序列组还未定论。
针对相关技术中无法确定信道或信号使用的序列组或CS的问题，目前还没有有效的解决方案。

下面结合本公开应用实施例进行详细说明。
本公开应用实施例包括以下14个具体实施例，如下：
应体实施例1
描述PUCCH的序列组为按照其起始符号在slot中的符号位置计算的序列组，该序列组被使用为该PUCCH(包括每个跳频)。
在一个调度单元(例如一个slot，下文以slot为例进行描述)包含14个OFDM符号，编号从0～13。假设一个用户设备(UE)的PUCCH被配置起始符号为符号2，持续10个符号，也就是这PUCCH使用的符号为符号2～符号11。这里不管其是否跳频。由于PUCCH在slot中的起始符号是变化的，且持续符号数也是配置的，所以PUCCH的跳频位置也是变化的。
基站和UE按照下面等式推算该PUCCH的序列组。其中，u表示序列组的索引。Q为30，等于总的序列组个数。f ss被定义从小区物理ID得到，具体可以参考长期演进(LTE)协议的36.211的5.5.1.3节。n s为调度单元的编号，该编号按照NR***中的定义来取值。l(L的小写)是符号编号，从0～13，N是每个slot中包含的符号数，NR中取值为14。c(i)是一个伪随 机序列，其初始值为

是该小区的小区物理ID，或高层配置的一个虚拟小区物理ID。
u＝(f gh(n s,l)+f ss)mod Q  等式1
Figure PCTCN2018114785-appb-000010
这样，通过等式1和2，可以计算得到一个slot中每个OFDM符号对应的序列组。对于上面的例子中，PUCCH的起始符号为符号2，那么该PUCCH使用的序列组则为按照l取值为2时计算得到的序列组。
应用实施例2
对于跳频的PUCCH，描述PUCCH的每个跳频的序列组为按照其每个跳频(hop)的起始符号在slot中的符号位置计算的序列组，该序列组被使用为该PUCCH的跳频。
由于PUCCH在slot中的起始符号是变化的，且持续符号数也是配置的，所以PUCCH的跳频位置也是变化的，本具体实施例中，对于跳频的PUCCH，按照每个跳频的第一个符号在slot中的符号位置来计算序列组。
在一个slot包含14个OFDM符号，编号从0～13。假设一个UE的PUCCH被配置起始符号为符号2，持续10个符号，也就是这PUCCH使用的符号为符号2～符号11，且跳频，跳频图样为5/5跳频，即前5个符号为一个跳频，后5个符号为一个跳频，这样对应到slot中，即该PUCCH的跳频符号为在符号6和符号7之间。
基站和UE按照应用实施例1中的等式1和2来计算序列组。此时第一个跳频的序列组计算时，l取值为2，第二个跳频的序列组计算时l取值为7。对应其他参数按照约定进行取值即可。具体的计算不再赘述。
应用实施例3
对于PUCCH的序列组，可以按照其某一符号在slot中的符号位置计算其使用的序列组，为整个PUCCH使用。所述某一符号在slot中的符号位置 可以是基站配置的。
这里，按照某一符号计算得到PUCCH使用的序列组，主要目的是，为了支持可能灵活复用。例如，一个PUCCH有10个符号，另一个PUCCH有6个符号，这里假设都不跳频(如果跳频的话，下面介绍的原理是不变的)。此时，6个符号的PUCCH复用在10个符号的PUCCH的后6个符号中使用相同的资源，通过CS或结合正交覆盖编码(Orthogonal Cover Code，简称为OCC)方式复用，此时需要这两个PUCCH在复用的6个符号中有相同的序列组，所以，此时10个符号的PUCCH的序列组计算使用被复用的6个符号中第一个符号在slot中的符号位置进行计算(计算方法同应用实施例1)。6个符号的PUCCH的序列组按照该PUCCH第一个符号在slot中的符号位置进行计算(也可以理解此时某一符号被定义为该PUCCH的第一个符号)。这样就保证了复用的两个PUCCH使用了相同的序列组(只需要在复用的6个符号中序列组必须相同，对于10个符号的PUCCH的前4个符号中使用的序列组也可以使用与后6个符号相同的序列组，也可以利用该PUCCH的第一个符号在slot中的符号位置来计算)。
这里所述的某一符号是基站配置的，例如基站预计对于10个符号的UE将采用上述的复用方式，基站能通知该UE，它的PUCCH的序列组计算按照该10个符号中的第5个计算(实际计算时，需要将所述第5个符号换算为其在slot中的符号位置)。然后，基站和UE按照应用实施例1中等式1和2来计算序列组。具体的计算不再赘述。
应用实施例4
对于PUCCH，其序列组为可以按照某一符号在slot中的符号位置计算得到的序列组，该序列组被使用从所述某一符号开始持续使用直到有新的序列组(这个新的序列组被计算根据另一个符号在slot中的符号位置)。
这里实际上和应用实施例3有些类似。
例如，一个12个符号的PUCCH(记为PUCCH1)，将被分段与3个PUCCH(分别记为PUCCH2，PUCCH3，PUCCH4)复用，每个PUCCH有4个符号。例如，PUCCH2和PUCCH1复用在PUCCH1的前4个符号， PUCCH3和PUCCH1复用在PUCCH1中间4个符号，PUCCH4和PUCCH1复用在PUCCH1的后4个符号。复用的PUCCH在复用符号中要使用相同的序列组。那么此时PUCCH1的序列组需要分别按照3段计算，第一段的序列组计算时可以按照PUCCH1的第一个符号在slot中符号位置进行计算，该序列组被使用在PUCCH1的前4个符号。PUCCH1的中间4个符号的序列组按照PUCCH1的第5个符号在slot中的符号位置计算，该序列组被使用在PUCCH1的中间4个符号(PUCCH1的第5个符号至第8个符号)。PUCCH1的后4个符号的序列组按照PUCCH1的第9个符号在slot中的符号位置计算得到，该序列组被使用在PUCCH1的后4个符号中。
PUCCH2，PUCCH3和PUCCH4的序列组按照各自的第一个符号在slot中的符号位置计算得到。
这样按照应用实施例1中的等式1和2就可以分别计算得到PUCCH1的不同段的序列组。本应用实施例中举例的具体数据可以被替换为其他合理数据，可以采用上位描述。
应用实施例5
描述PUCCH的序列组为按照该PUCCH所在slot中的某一上行符号位置计算的序列组，该序列组被使用为该PUCCH(包括每个跳频)。
这里，slot中的某一上行符号位置可以是slot中第一个上行符号位置。本应用实施例中，PUCCH的序列组计算时，使用了PUCCH所在slot中的第一个上行符号的符号位置。例，在NR***中，每个slot中符号的属性(即上行符号或下行符号)是基站可以配置的，所以slot中的包含的上行符号的符号位置和数量都是在变化的。这里如果一个PUCCH在一个slot中，该slot中第一个上行符号为符号3(符号编号从0～13)，那么这个PUCCH的序列组计算时，使用符号3来计算序列组。例如，使用应用实施例1中的等式1和2，此时l的取值为3。计算得到的序列组应用于该PUCCH(这里不管PUCCH是否跳频)。
进一步地，如果序列组要求在不同的跳频之间变化时，此时上面得到的序列组为PUCCH第一个跳频使用。再根据slot中第二上行符号位置计算 得到的序列组用于该PUCCH第二个跳频。
在NR***中，UE是可以根据相关信令得到slot类型中符号的属性的。
应用实施例6
描述PUCCH的序列组为按照该PUCCH的每个符号在slot中的符号位置计算得到PUCCH每个符号中的序列组，这里不管PUCCH是否跳频。
本应用实施例中，例如，5个符号的PUCCH在slot中使用了部分符号，假设从slot的符号2开始至slot的符号6，那么该PUCCH的序列组是按照符号计算的，每个符号都可以有不同的序列组。例如，这个PUCCH的第1个符号至第5个符号分别使用的序列组按照slot中的符号2至符号6分别计算得到。
这样PUCCH每个符号使用的序列组都是不同的，且是根据PUCCH每个符号在slot中的符号位置计算得到的。
具体的计算可以使用应用实施例1中的等式1和2。
这里，也可以将slot中符号分组，根据每一组的第1个符号在slot中的符号位置计算该符号组使用的序列组。这样对于一个PUCCH，如果该PUCCH的符号落在哪个符号组，那么该PUCCH的符号就是使用这个符号组对应的序列组。例如，slot中的符号分为7组，每组2个符号，slot中符号0和1是第一个符号组，符号2和3是第二个符号组，符号4和5是第三个符号组，.....。如果一个PUCCH包含8个符号，起始符号为slot中的符号0，持续至符号7。那么此时该PUCCH的前2个符号的序列组为slot中的第一个符号组计算得到的序列组，顺序的，PUCCH再2个符号的序列组为slot中的第二个符号组计算得到的序列组，PUCCH再2个符号的序列组为slot中第3个符号组计算得到序列组，PUCCH再2个符号的序列组为slot中第4个符号组计算得到序列组。
应用实施例7
描述PUCCH的CS为按照其起始符号在slot中的符号位置计算的
Figure PCTCN2018114785-appb-000011
然后再结合基站配置的初始CS 0计算得到一个CS为该PUCCH(包括每个跳频)。其中，l为所述起始符号在slot中的符号索引。
基本思想与应用实施例1相似，只是计算具体方法和计算的对象不同。
这里，

按照等式3计算。其中，n s为调度单元的编号，该编号按照NR***中的定义来取值。l(L的小写)是符号编号，从0～13，N是每个slot中包含的符号数，NR***中取值为14。c(i)是一个伪随机序列，其初始值为

将

和CS 0结合，可以按照等式4计算对应的符号l使用的CS。CS 0是基站配置给UE。
Figure PCTCN2018114785-appb-000016
Figure PCTCN2018114785-appb-000017
假设有一个PUCCH占用6个符号，从slot中的符号2至符号7，那么该PUCCH在每个符号中的CS是按照该PUCCH起始符号在slot中的符号位置来计算，即l取值为2计算得到CS，将该CS应用到该PUCCH的所有符号中。
应用实施例8
对于跳频的PUCCH，描述PUCCH的每个跳频的CS为按照其每个跳频(hop)的起始符号在slot中的符号位置计算的
Figure PCTCN2018114785-appb-000018
然后再结合基站配置的初始CS 0计算得到一个CS为该PUCCH的跳频。其中，l为所述起始符号在slot中的符号索引。
基本思想与应用实施例2相似，只是计算具体方法和计算的对象不同。
该应用实施例指示按照PUCCH的每个跳频分别计算每个跳频中使用的CS。例如一个PUCCH有8个符号，从slot的符号2至符号9，且跳频， 第一个跳频为前4个符号，第二个跳频为后4个符号(也就是跳频位置在slot的符号5和符号6之间)。
此时计算PUCCH第一个跳频的CS时，l取值为2，计算第二个跳频的CS时，l取值为6，分别根据具体实施例7中计算等式得到2个CS分别应用与第一个跳频的所有符号和第二个跳频的所有符号。
应用实施例9
对于PUCCH的CS，可以按照其某一符号在slot中的符号位置计算的
Figure PCTCN2018114785-appb-000019
再结合基站配置的初始CS 0计算得到一个CS为整个PUCCH使用。所述某一符号在slot中的符号位置可以是基站配置的。其中，l为所述起始符号在slot中的符号索引。
基本思想与应用实施例3相似，只是计算具体方法和计算的对象不同。
这里，按照某一符号计算得到PUCCH使用的序列组，主要目的是，为了支持可能灵活复用。例如，一个PUCCH有10个符号，另一个PUCCH有6个符号，这里假设都不跳频(如果跳频的话，下面介绍的原理是不变的)。此时，6个符号的PUCCH复用在10个符号的PUCCH的后6个符号中使用相同的资源，通过CS或结合OCC方式复用，此时需要这两个PUCCH在复用的6个符号中有对应的CS，所以，此时10个符号的PUCCH的CS使用被复用的6个符号中第一个符号在slot中的符号位置进行计算(计算方法同具体实施例7)。6个符号的PUCCH的CS按照该PUCCH第一个符号在slot中的符号位置进行计算(也可以理解此时某一符号被定义为该PUCCH的第一个符号)。这样就保证了复用的两个PUCCH有对应的CS。
这里所述的某一符号是基站配置的，例如基站预计对于10个符号的UE将采用上述的复用方式，基站能通知这个UE，它的PUCCH的CS计算按照该10个符号中的第5个计算(实际计算时，需要将所述第5个符号换算为其在slot中的符号位置)。然后，基站和UE按照具体实施例7中等式3和4来计算CS。具体的计算不再赘述。
应用实施例10
对于PUCCH，其CS为可以按照某一符号在slot中的符号位置计算的

再结合基站配置的初始CS计算得到一个CS，该CS被使用从所述某一符号在slot中的符号位置开始持续使用直到有新的CS(这个新的CS被计算根据另一个符号在slot中的符号位置)。
基本思想与应用实施例4相似，只是计算具体方法和计算的对象不同。
例如，一个12个符号的PUCCH(记为PUCCH1)，将被分段与3个PUCCH(分别记为PUCCH2，PUCCH3，PUCCH4)复用，每个PUCCH有4个符号。例如，PUCCH2和PUCCH1复用在PUCCH1的前4个符号，PUCCH3和PUCCH1复用在PUCCH1中间4个符号，PUCCH4和PUCCH1复用在PUCCH1的后4个符号。复用的PUCCH在复用符号中是要使用CS的。那么此时PUCCH1的CS需要分别按照3段计算，第一段的CS计算时可以按照PUCCH1的第一个符号在slot中符号位置进行计算，该CS被使用在PUCCH1的前4个符号。PUCCH1的中间4个符号的CS按照PUCCH1的第5个符号(也就是每段的第一个符号)在slot中的符号位置计算，该CS被使用在PUCCH1的中间4个符号(PUCCH1的第5个符号至第8个符号)。PUCCH1的后4个符号的CS按照PUCCH1的第9个符号在slot中的符号位置计算得到，该CS被使用在PUCCH1的后4个符号中。
PUCCH2，PUCCH3和PUCCH4的CS按照各自的第一个符号在slot中的符号位置计算得到。
这样按照应用实施例7中的等式3和4就可以分别计算得到PUCCH1的不同段的CS。本具体实施例中举例的具体数据可以被替换为其他合理数据，可以采用上位描述。

描述PUCCH的CS为按照该PUCCH所在slot中的某一上行符号位置计算的
Figure PCTCN2018114785-appb-000021
再结合基站配置的初始CS计算得到一个CS，该CS被使用为该PUCCH(包括每个跳频)。这里slot中的某一上行符号位置可以是 slot第一个上行符号位置。
基本思想与应用实施例5相似，只是计算具体方法和计算的对象不同。
这里，slot中的某一上行符号位置可以是slot第一个上行符号位置。本应用实施例中，PUCCH的CS计算时，使用了PUCCH所在slot中的第一个上行符号的符号位置。例，在NR***中，每个slot中符号的属性(即上行符号或下行符号)是基站可以配置的，所以slot中的包含的上行符号的符号位置和数量都是在变化的。这里如果一个PUCCH在一个slot中，该slot中第一个上行符号为符号3(符号编号从0～13)，那么计算这个PUCCH的CS时，使用符号3来计算CS。例如，使用应用实施例7中的等式3和4，此时l的取值为3。计算得到的CS应用该PUCCH(这里不管PUCCH是否跳频)。

再结合基站配置的初始CS计算得到该PUCCH每个符号上的CS，不管该PUCCH是否跳频。
基本思想与应用实施例6相似，只是计算具体方法和计算的对象不同。
本应用实施例中，例如，5个符号的PUCCH在slot中使用了部分符号，假设从slot的符号2开始至slot的符号6，那么该PUCCH的CS是按照符号计算的，每个符号可以都有不同的CS。例如，这个PUCCH的第1个符号至第5个符号分别使用的CS按照slot中的符号2至符号6分别计算得到。
这样PUCCH每个符号使用的CS是不同的，且是根据PUCCH每个符号在slot中的符号位置计算得到的。具体的计算可以使用应用实施例7中的等式3和4。
这里，也可以将slot中符号分组，根据每一组的第1个符号在slot中的符号位置计算该符号组使用的CS。这样，对于一个PUCCH，如果该PUCCH的符号落在哪个符号组，那么该PUCCH的符号就是使用这个符号组对应的CS。例如，slot中的符号分为7组，每组2个符号，slot中符号0和1是第一个符号组，符号2和3是第二个符号组，符号4和5是第三个符号组，.....。如果一个PUCCH包含8个符号，起始符号为slot中的符号0，持续至符号7。那么此时该PUCCH的前2个符号的CS为slot中的第一个符号组计算得到的CS，顺序的，PUCCH再2个符号的CS为slot中的第二个符号组计算得到的CS，PUCCH再2个符号的CS为slot中第3个符号组计算得到CS，PUCCH再2个符号的CS为slot中第4个符号组计算得到CS。
应用实施例13
下面提供一种方法，它能被发送端(基站)或接收端(UE)使用，以来确定信道或信号的序列组或CS。例如确定上行或下行物理信道或信号，方法具体为(以确定PUCCH使用的序列组为例描述)：
将无线帧的每个调度单元中前7个符号和后7个符号分别编号(或者将无线帧中从第一个符号开始，每7个符号编一个号，NR中每个调度单元有14个符号)，编号从0开始，且是无线帧中第一个slot中第一个7个符号。编号记为Ks。然后按照Ks计算每个Ks对应的序列组，这样每个调度单元得到2个序列组。UE在一个调度单元只有一个PUCCH且不调频时，将每个调度单元得到第一个或第二个序列组应用于UE在该调度单元中的PUCCH，具体用于那个序列组可以是基站和UE事先约定的或者由基站指示给UE。
UE在一个调度单元只有一个PUCCH且调频时，将每个调度单元得到第一个(或第二个)序列组应用于UE在该调度单元中的PUCCH的第一个跳频；将每个调度单元得到第二个(或第一个)序列组应用于所述UE在该调度单元中的PUCCH的第二个跳频。如果UE在该调度单元中有多个PUCCH，且都跳频，上述方式能被使用为每个PUCCH。
如果UE在该调度单元中有多个PUCCH，且都不跳频，则将该调度单 元得到的第一个序列组应用于所述UE在该调度单元中所有奇数(或偶数)PUCCH(标号从0开始)，将该调度单元得到的第二个序列组应用于所述UE在该调度单元中所有偶数(或奇数)PUCCH(标号从0开始)。
如果UE在该调度单元中有多个PUCCH，且都不跳频，则将该调度单元得到的第一个序列组应用于所述UE在该调度单元中每个PUCCH按照跳频时第一个跳频对应的符号，将该调度单元得到的第二个序列组应用于为所述UE在该调度单元中每个PUCCH按照跳频时第二个跳频对应的符号。
具体使用Ks计算等式如下：

上述各实施例的技术特征在不冲突时可以结合使用。
应用实施例14
本具体实施例14给出一种方法，该方法解决不同的UE的上行控制信息和DMRS之间的复用问题。例如，UE1的上行控制信息和UE2的DMRS复用问题。上行控制信息可以包含ACK/NACK、SR和一些信道测量信息。上行控制信息可以通过物理上行控制信道PUCCH来承载，这样本实施例也可以是解决不同UE的PUCCH的复用问题。
为UE1分配一个循环移位CS0(一个序列有不同的CS，例如序列长度为12，就有12个循环移位，记为CS0～CS11。这里的CS编号只是一个举例，其他CS值也可以的，下同)，用于承载UE1的ACK或NACK，为UE1分配一个CS8用于承载UE1的DMRS；为UE1分配一个CS4承载UE1的ACK/NACK和SR。具体为：当UE1只有ACK或NACK传输时，使用CS0， 并将对应的ACK或NACK信息调制到CS0上发送。当UE1有ACK或NACK要传输，同时进行SR请求时，例如使用“1”表示，此时将“1”调制到CS4上发送。当UE1有ACK或NACK要传输，同时不进行SR请求时，例如使用“0”，此时将“0”调制到CS4上发送(先将0通过调制变为-1，然后调制到CS上)。
为UE2做类似处理，也分配为CS0，CS4和CS8表示含义相同。
UE1和UE2的PUCCH或上行控制信息和DMRS复用为：在相同的时频资源中，在第一符号中，UE1发送上行控制信息的CS(例如UE1的CS0或CS4)，同时该符号中UE2发送DMRS。在第二符号中，UE2发送上行控制信息的CS(例如UE2的CS0或CS4)，同时该符号中UE1发送DMRS。
这样，在一些符号中，UE1的上行控制信息和UE2的DMRS通过不同的CS进行复用。在另一些符号中，UE1的DMRS和UE2的上行控制信息通过不同的CS进行复用。当有2个UE时，一个符号中需要3个有CS(如上面的例子)，这样如果序列的长度为12，那么3个CS的间隔最大可以4。当有更多的UE时，上述的方法仍然能被使用，在同一符号中，至少有一个UE的DMRS和其他至少一个UE的上行控制信息。在其他同一符号中，至少有一个UE的上行控制信息和其他至少一个UE的DMRS。它们通过不同的CS复用在相同的资源中。
由上述内容可知，在不同UE的上行控制信息和DMRS复用的OFDM符号中，在一些符号中至少有一个UE1的DMRS和其他至少一个UE2的上行控制信息通过CS复用在相同资源中；在另一符号中至少有一个UE2的DMRS和其他至少一个UE1的上行控制信息通过CS复用在相同资源中。上行控制信息包括至少之一：ACK，NACK和SR。它们通过调制到CS上进行承载。
