其中,上述第一UCI和第二UCI可以是不同的业务的UCI,例如:第一UCI为第一业务的UCI,第二UCI可以是第二业务的UCI。另外,本公开实施例中,UCI包括但不限于:混合自动重传请求确认(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)、信道状态信息(Channel State Information,CSI)、调度请求(Scheduling Request,SR)等中的至少一项。
另外,本公开实施例中,第一业务可以是URLLC业务,第二业务可以是eMBB业务,当然,对此不作限定,例如:第一业务或者第二业务可以是海量机器类通信(Massive Machine Type Communication,mMTC),或者第一业务和第二业务还可以是后续通信系统中引入的不同业务。其中,本公开实施例中主要以第一业务是URLLC业务,第二业务是eMBB业务进行举例说明。
而上述第一上行信道和第二上行信道可以是物理上行控制信道(Physical Uplink Control Channel,PUCCH),例如:承载所述第一UCI的PUCCH可以称作第一PUCCH,承载所述第二UCI的PUCCH可以称作第二PUCCH。当然,上述第一上行信道和第二上行信道也可以是物理上行共享信道(Physical  Uplink Shared Channel,PUSCH),例如:承载所述第一UCI的PUSCH可以称作第一PUSCH,承载所述第二UCI的PUSCH可以称作第二PUSCH。
另外,上述承载所述第一UCI的第一上行信道的传输时域资源与承载第二UCI的第二上行信道的传输时域资源存在重叠可以是,第一上行信道的传输时域资源与第二上行信道的传输时域资源存在部分或者全部资源重叠,例如:如图3所示,第一PUCCH的传输时域资源与第二PUCCH的传输时域资源重叠。
而上述将所述第一UCI和所述第二UCI复用在同一信道上传输可以是,将所述第一UCI和所述第二UCI的全部或者部分比特复用在同一信道上传输,例如:将第一UCI的全部比特,以及将第二UCI的全部或者部分比特复用在上述第一上行信道上传输。当然,在一些情况下,可以丢弃第一UCI和所述第二UCI的一个UCI,以保证另一个UCI传输,例如:在第一上行信道的最大码率不允许传输第一UCI和第二UCI的所有比特的情况下,可以丢弃第二UCI的全部或者部分比特。另外,上述传输可以是向网络设备发送。
本公开实施例中,通过上述步骤可以实现将所述第一UCI和所述第二UCI复用在同一信道上传输,从而避免UCI传输冲突,以提高终端传输UCI的效果。
作为一种可选的实施方式,上述同一信道是所述第一上行信道。
这样可以实现使用第一上行信道和第二上行信道中上行信道进行传输,而不需要额外增加信道,降低复杂度。
可选的,所述第一UCI的优先级高于所述第二UCI的优先级。
例如:第一UCI为URLLC业务的UCI,第二UCI为eMBB业务的UCI。
这样可以实现在优先级高的UCI对应的上行信道上复用传输第一UCI和所述第二UCI,以保证高优先级的UCI的传输的同时兼顾低优先级的UCI的传输。
其中,UCI的优先级可以是根据对应物理信令确定,即物理层信令能够区分不同UCI的优先级。例如:根据UCI对应的下行控制信息(Downlink Control Information,DCI)确定的。可选的,所述第一UCI对应的DCI为:
特定格式的DCI、采用特定无线网络临时标识(Radio Network Temporary  Identifier,RNTI)加扰的DCI或者配置有特定调制与编码策略表(Modulation and Coding Scheme,MCS)的DCI。
其中,上述第一UCI对应的DCI可以是,第一UCI的业务关联的DCI,如用于调度该业务的传输,或者用于配置该业务的传输配置等关联的DCI。
这样可以实现使用DCI格式、DCI加扰的RNTI或者MCS表等确定UCI的优先级。例如:如高优先级的UCI(包括HARQ-ACK,SR,CSI)指相应于下述的UCI:
一个特定的DCI格式;
或者使用特定RNTI加绕的DCI;
或者DCI中配置特定MCS表;
例如:低优先级的UCI(包括HARQ-ACK,SR,CSI)指相应于下述的UCI:
除了上述特定DCI格式的其他DCI格式,
或者除了特定RNTI的其他RNTI加绕的DCI,
或者DCI中配置的除了上述特定MCS表的其他MCS表。
另外,本公开实施例中,上述特定格式的DCI可以是预设格式的DCI,例如:网络配置、协议约定等;而上述采用特定RNTI加扰的DCI可以是采用预设RNTI加扰的DCI,例如:网络配置、协议约定等,如调制与编码策略小区无线网络临时标识(Modulation and Coding Scheme Cell Radio Network Temporary Identifier,MCS-C-RNTI)加扰的DCI;而上述配置有特定MCS表的DCI可以是配置有预设MCS表的DCI,例如:配置有网络配置、协议约定的MCS表的DCI,如低频谱效率的MCS表。
该实施方式中,由于可以通过对应的DCI确定UCI的优先级,从而避免增加额外的指示,以节约开销。
作为一种可选的实施方式,上述若所述第一上行信道为第一PUCCH,所述第二上行信道为第二PUCCH,则所述将所述第一UCI和所述第二UCI复用在同一信道上传输,包括:
将所述第一UCI和所述第二UCI复用在承载所述第一UCI的第一PUCCH的PUCCH资源上传输。
该实施方式中,可以实现在第一UCI和第二UCI承载在PUCCH上传输的情况下,将所述第一UCI和所述第二UCI复用在承载所述第一UCI的第一PUCCH的PUCCH资源上传输。例如:如果URLLC的HARQ-ACK和eMBB的HARQ-ACK在PUCCH上传输,使用URLLC的PUCCH资源承载URLLC的HARQ-ACK和eMBB的HARQ-ACK。
其中,上述PUCCH资源可以依据所述复用的总比特数确定。
可选的,所述总比特数包括:
所述第一UCI的比特数和所述第二UCI的比特数之和;或者
所述第一UCI的比特数和所述第二UCI的折算比特数之和,其中,所述第二UCI的折算比特数为所述第二UCI的比特数的函数。
其中,上述函数可以是预设函数,例如:协议中约定或者网络配置的,如上述函数可以为实际比特数乘以折算因子,即上述第二UCI的折算比特数等于第二UCI的实际比特乘以折算因子得到的比特数。其中,该折算因子可以预先配置的,例如:协议中约定或者网络配置的。
需要说明的是,本公开实施例中,在总比特数确定后,如何确定PUCCH资源的方式不作限定,例如:可以是先基于总比特数确定包括上述PUCCH资源的PUCCH资源集,再在该PUCCH资源集中确定上述PUCCH资源。具体可以采用协议中定义确定PUCCH资源的方式,或者采用协议中后续引入的确定PUCCH资源的方式。由于PUCCH资源可以依据所述复用的总比特数确定,从而避免资源浪费。
下面以第一UCI为URLLC的HARQ-ACK,第二UCI为eMBB的HARQ-ACK进行举例说明,这样可以实现PUCCH资源集确定基于如下:
URLLC的HARQ-ACK和eMBB的HARQ-ACK总的比特数,或者
URLLC的HARQ-ACK比特数+折算后的eMBB的HARQ-ACK比特数。
具体可以如下:
对于PUCCH的资源集确定基于URLLC的HARQ-ACK比特数+折算后的eMBB的HARQ-ACK比特数。一种折算方式:
折算的eMBB HARQ-ACK bit数等于如下:
eMBB HARQ-ACK bit数*(MaxCodeRate 1(用于URLLC)/MaxCodeRate  2(用于eMBB))
其中,MaxCodeRate 1(用于URLLC)和MaxCodeRate 2(用于eMBB)分别为高层配置的用于传输URLLC和eMBB业务的PUCCH的最大码率。
另外,上述实施方式中,第一UCI在所述PUCCH资源中使用的第一物理资源块(Physical Resource Block,PRB)数量可以为不超过第一PUCCH格式的最大码率时的最小PRB数量;
而上述第二UCI在所述PUCCH资源中使用的第二PRB数量可以为不超过第二PUCCH格式的最大码率时的最小PRB数量。
另外,若所述第二PRB数量大于第三PRB数量,则可以丢弃所述第二UCI的比特,直到所述第二PRB数量小于或者等于所述第三PRB数量,所述第三PRB数量等于所述PUCCH资源的最大PRB数量减去所述第一PRB数量;
其中,所述第一PUCCH格式为所述第一UCI使用的PUCCH格式,所述第二PUCCH格式为所述第二UCI使用的PUCCH格式。
例如:以第一UCI为URLLC的HARQ-ACK,第二UCI为eMBB的HARQ-ACK为例,对于确定PUCCH资源集后,确定PUCCH资源集中的RB数可以按照如下规则确定:
如果终端使用包含

个PRB的PUCCH格式2或格式3传输O ACK1个URLLC信息bit和O CRC1bit;
对于URLLC HARQ-ACK需要的PRB,终端确定小于或等于配置的高层配置的PUCCH-format2的nrofPRBs1或者PUCCH-format3的nrofPRBs1的最小PRB:

而对于eMBB HARQ-ACK需要的PRB,终端确定小于或等于配置的高层配置的PUCCH-format2的nrofPRBs2或PUCCH-format3的nrofPRBs2的最小PRB:

为子载波数,
Figure PCTCN2020098831-appb-000015
为UCI占用的符号数,Q m2为eMBB PUCCH的UCI的调制方式,r2为配置的用于eMBB业务的PUCCH的最大码率MaxCodeRate 2(用于eMBB)。
nrofPRBs1可以等于nrofPRBs2,也可以不等于nrofPRBs2。
如果
Figure PCTCN2020098831-appb-000016
丢弃部分或全部eMBB的HARQ-ACK bit直到
Figure PCTCN2020098831-appb-000017

Figure PCTCN2020098831-appb-000019
个PRB传输用于URLLC的PUCCH传输URLLC的HARQ-ACK bit,并且丢弃eMBB的HARQ-ACK。
在上述过程终端分别确定在第一PUCCH上承载第一UCI需要的PRB数以及在第一PUCCH上承载第二UCI需要的PRB数。第一UCI和第二UCI需要的最大PRB数,不超过第一PUCCH的资源集内最大的允许PRB数。可选的,在上述将所述第一UCI和所述第二UCI复用在承载所述第一UCI的第一PUCCH的PUCCH资源上传输的实施方式中,第一UCI和所述第二UCI可以联合编码或者分别独立编码,且可以使用不同的码率或者相同的码率。例如:
在所述第一UCI和所述第二UCI的联合编码的情况下,若所述联合编码的码率超过所述第一PUCCH的最大码率,则丢弃所述第二UCI的比特,直到所述联合编码的码率不超过所述第一PUCCH的最大码率;或者
在所述第一UCI和所述第二UCI分别独立编码的情况下,若所述第二UCI编码后的码率超过所述第二PUCCH的最大码率,则丢弃所述第二UCI的比特,直到所述第二UCI编码后的码率不超过所述第二PUCCH的最大码率。
其中,上述最大码率可以是预先配置的,例如:网络配置或者协议约定等。
该实施方式中,可以保证述第一UCI的传输码率,从而实现保证高优先级的UCI的传输的同时兼顾低优先级的UCI的传输。
下面以URLLC的HARQ-ACK和eMBB的HARQ-ACK进行举例:
如果复用URLLC的HARQ-ACK和eMBB的HARQ-ACK后,导致URLLC的实际传输码率超过URLLC的PUCCH配置的最大码率,则丢弃部分或全部eMBB的HARQ-ACK直到实际传输码率低于配置的URLLC的PUCCH最大码率。如果eMBB的HARQ-ACK实际传输码率大于配置的eMBB的PUCCH的最大码率(如果存在)则丢弃部分eMBB(可以按照预配置的顺序)的HARQ-ACK bit,直到实际传输码率低于配置的PUCCH的最大码率,或者丢弃全部eMBB的HARQ-ACK bit。
例如:URLLC的HARQ-ACK和eMBB的HARQ-ACK可以采用联合编码。一种方法是把URLLC的HARQ-ACK和eMBB的HARQ-ACK级联然后编码,编码后的码率小于URLLC的PUCCH的最大码率(例如:由高层参数PUCCH-MaxCodeRate确定)。PUCCH资源集根据使用URLLC的HARQ-ACK和eMBB的HARQ-ACK总的bit数确定。
又例如:URLLC的HARQ-ACK和eMBB的HARQ-ACK独立编码并使用不同的码率,即URLLC的HARQ-ACK编码后的码率不超过配置的URLLC的PUCCH最大码率(例如:由高层参数PUCCH-MaxCodeRate 1确定,相应于高优先级业务的PUCCH最大码率)。eMBB的HARQ-ACK编码后的码率不超过配置的eMBB的PUCCH的最大码率(由高层参数PUCCH-MaxCodeRate 2确定,相应于低优先级业务的PUCCH的最大码率)。
可选的,在所述第一UCI和所述第二UCI分别独立编码的情况下,上述第一UCI编码后的比特映射在所述PUCCH资源中前j个符号组上;
其中,若所述前j个符号组的最后一个符号组被所述第一UCI编码后的比特全部占用,则所述第二UCI编码后的比特映射在所述PUCCH资源中的剩余符号组上;或者,若所述第一UCI编码后的比特无法占用所述前j个符号组的最后一个符号组的全部资源单元,则所述在所述最后一个符号组中的每个符号按照尽可能平均分配的方式承载所述第一UCI编码后的比特,所述第二UCI编码后的比特映射在所述前j个符号组的最后一个符号组的剩余资源单元和所述PUCCH资源中的剩余符号组上。
下面以URLLC的HARQ-ACK和eMBB的HARQ-ACK为例,对于 PUCCH资源映射,当URLLC的HARQ-ACK和eMBB的HARQ-ACK分别编码时,按照表1的映射方式进行映射:

Figure PCTCN2020098831-appb-000028
例如:先把URLLC的HARQ-ACK编码后的bit映射到第1到第j-1个OFDM符号组上,占用全部的资源单元,如果第1到第j-1个OFDM符号组中最后一个OFDM符号组上占用了全部的资源单元,此时,承载eMBB的HARQ-ACK的编码后的bit占用剩余的OFDM符号组。
如果第1到第j-1个OFDM符号组中最后一个OFDM符号组上承载URLLC的HARQ-ACK编码后的bit无法占用全部的资源单元。则第1到第j-1个中OFDM符号组最后一个OFDM符号组内每个OFDM符号尽可能平均地承载URLLC的HARQ-ACK编码后的bit。在第1到第j-1个OFDM符号组中最后一个OFDM符号组的其他位置和剩余的OFDM符号组上放置eMBB的HARQ-ACK的编码后的bit。例如:URLLC的HARQ-ACK编码后的bit经过前面的OFDM符号组映射之外,只剩下10个资源单元,最后的OFDM符号组包括4个OFDM符号,从而将10个资源单元以尽可能平均分配的方式承载在第1到第j-1个OFDM符号组中最后一个OFDM符号组的各OFDM符号上,如将4个资源单元分别映射至4个OFDM符号的第一个子载波上,再将另4个资源单元分别映射至4个OFDM符号的第二个子载波上,以及将另外2个资源单元映射到第一OFDM符号和第二OFDM符号的第三个子载波上。由于尽可能平均的映射,从而可以提高UCI的传输性能。
作为一种可选的实施方式,若所述第一上行信道和所述第二上行信道为PUSCH,则所述将所述第一UCI和所述第二UCI复用在同一信道上传输,包括:
将所述第一UCI和所述第二UCI复用在承载所述第一UCI的第一PUSCH上传输。
该实施方式中,可以实现在第一UCI和第二UCI承载在PUSCH上传输的情况下,将所述第一UCI和所述第二UCI复用在承载所述第一UCI的第一PUSCH的PUCCH资源上传输。例如:如果URLLC的HARQ-ACK和eMBB的HARQ-ACK在PUSCH上传输,将URLLC的HARQ-ACK和eMBB的HARQ-ACK复用在承载URLLC的HARQ-ACK的PUSCH上传输。
可选的,上述第一UCI和所述第二UCI在每层中占用的调制编码符号数是依据所述复用的总比特数确定。
其中,上述第一UCI和所述第二UCI在每层中占用的调制编码符号数可以是,第一UCI和所述第二UCI在复用的PUSCH的每层中占用的调制编码符号数。
其中,上述第一UCI和所述第二UCI在每层中占用的调制编码符号数是依据所述复用的总比特数确定可以是,上述第一UCI和所述第二UCI在每层中占用的调制编码符号总数是依据所述复用的总比特数确定,例如:上述第一UCI在每层中占用的调制编码符号数是依据所述复用的总比特数中第一UCI的比特数确定,上述第二UCI在每层中占用的调制编码符号数是依据所述复用的总比特数中第二UCI的比特数确定。
需要说明的是,本公开实施例中,在总比特数确定后,如何确定每层中占用的调制编码符号数的方式不作限定,例如:可以采用协议中定义确定每层中占用的调制编码符号数的方式,或者采用协议中后续引入的每层中占用的调制编码符号数的方式。由于每层中占用的调制编码符号数可以依据所述复用的总比特数确定,从而避免资源浪费。
另外,上述总比特数可以包括:
所述第一UCI的比特数和所述第二UCI的比特数之和;或者
所述第一UCI的比特数和所述第二UCI的折算比特数之和,其中,所述第二UCI的折算比特数为所述第二UCI的比特数的函数。
其中,上述函数可以为实际比特数乘以折算因子。
其中,上述总比特数可以参见上述PUCCH的实施方式的相应说明,此处不作赘述。
下面以第一UCI为URLLC的HARQ-ACK,第二UCI为eMBB的HARQ-ACK进行举例说明:
对于分别编码,用于确定URLLC的HARQ-ACK和eMBB的HARQ-ACK占用的每层的调制编码符号数的bit数,根据下式确定总bit数为:
URLLC的HARQ-ACK比特数+折算后的eMBB的HARQ-ACK比特数=URLLC的HARQ-ACK比特数+eMBB的HARQ-ACK比特数*gamma
其中gamma为折算因子(或称作伸缩因子)。
例如:对于在有数据的PUSCH的HARQ-ACK传输每层的调制编码符号数表示为Q′ ACK1+Q′ ACK2,其中Q′ ACK1为URLLC的HARQ-ACK传输每层的调制编码符号数,Q′ ACK2为eMBB的HARQ-ACK传输每层的调制编码符号数。

还以是UCI为HARQ-ACK为例,当承载高优先级业务的HARQ-ACK的PUCCH与承载低优先级业务HARQ-ACK的PUCCH重叠时,本公开实施例可以实现:
如果高优先级的HARQ-ACK和低优先级的HARQ-ACK在PUCCH上传输,使用高优先级的PUCCH资源承载高优先级的HARQ-ACK和低优先级的HARQ-ACK,该资源根据复用后总的bit数确定;
其中,高优先级的HARQ-ACK和低优先级的HARQ-ACK分别独立编码。可以使用不同的码率或者相同的码率。
PUCCH的资源集确定基于如下:
高优先级的HARQ-ACK和低优先级的HARQ-ACK总的比特数,或者
高优先级的HARQ-ACK比特数+折算后的低优先级的HARQ-ACK比特数。
如果高优先级的HARQ-ACK和低优先级的HARQ-ACK在PUSCH上传输,使用高优先级的PUSCH,高优先级的HARQ-ACK和低优先级的HARQ-ACK占用的每层的调制编码符号数,根据以下确定:
高优先级的HARQ-ACK和低优先级的HARQ-ACK总的比特数,或者

本公开实施例中,可以避免UCI传输冲突,以提高终端传输UCI的效果。例如:可以解决URLLC的PUCCH与eMBB PUCCH同时传输HARQ-ACK 的冲突问题,保证URLLC业务传输可靠性,及eMBB业务传输效率问题。
