相关申请的交叉引用
本申请主张在2018年9月26日在中国提交的中国专利申请号No.201811126073.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种上行控制信息的发送、接收方法、终端及网络设备。
背景技术
5G NR系统中相关技术不支持物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的同时传输，因此当PUCCH和PUSCH在时间上重叠时，需要将PUCCH承载的上行控制信息转移到PUSCH上和数据进行复用传输。
在多载波聚合的场景中，如果PUCCH和多个PUSCH在时间上重叠，且多个PUSCH载波的子载波间隔不同，按照相关技术中的规定在选择承载上行控制信息的PUSCH时并没有考虑PUSCH载波的子载波间隔，可能导致上行控制信息复用在子载波间隔较大的载波上进行传输，使上行控制信息的传输性能下降。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示，本公开的实施例提出一种上行控制信息的发送方法，应用于终端，所述方法包括：
步骤11，在物理上行控制信道(PUCCH)和多个物理上行共享信道(PUSCH)在时域上重叠，且多个PUSCH中存在至少两种不同的子载波间隔时，从所述多个PUSCH中，根据所述PUSCH的子载波间隔，选择PUSCH；
步骤12，采用选择的所述PUSCH，发送上行控制信息(UCI)。
本公开的该实施例，根据所述PUSCH的子载波间隔，选择PUSCH，可以避免UCI在子载波间隔较大载波传输导致传输性能下降的情况。
该实施例中，根据所述PUSCH的子载波间隔，选择PUSCH的具体实现方式包括如下几种方式：
1)多个PUSCH中，如果存在子载波间隔和PUCCH载波相同的PUSCH，选择子载波间隔和PUCCH载波相同的PUSCH。
例如：如图2所示，假设基站为终端配置了三个载波，其中载波1和载波3的子载波间隔配置为15kHz，载波2的子载波间隔配置为60kHz。
其中，载波1为PUCCH的传输载波，当在载波1的时隙n中存在PUCCH 传输时，如果同时基站调度了载波2和载波3上的PUSCH传输，如图2所示，在载波2的时隙4n、4n+1、4n+2、4n+3和载波3的时隙n中均存在PUSCH。则由于载波3的子载波间隔配置和载波1相同，终端选择将UCI复用在载波3的PUSCH上进行传输，丢弃载波1上时隙n中的PUCCH。
如果存在多个与PUCCH载波相同的PUSCH，则可以进一步的，从多个与PUCCH载波相同的PUSCH中，选择一个PUSCH；
如图3所示，假设基站为终端配置了五个载波，其中载波1、载波3、载波4和载波5的子载波间隔配置为15kHz，载波2的子载波间隔配置为60kHz。其中载波1为PUCCH的传输载波，当在载波1的时隙n中存在PUCCH传输时，如果同时基站调度了载波2、载波3、载波4和载波5上的PUSCH传输，如图3所示，在载波2的时隙4n、4n+1、4n+2、4n+3、载波3的时隙n、载波4的时隙n和载波5的时隙n中均存在PUSCH。则由于载波3、载波4和载波5的子载波间隔配置和载波1相同，终端优先选择将UCI复用在载波3、载波4或载波5的PUSCH上进行传输，进一步的，在选择出的三个PUSCH载波中，按照预设规则，首先确定载波4和载波5为基于调度的PUSCH载波，具有较高优先级，然后按照载波索引顺序优先选择载波4用于传输UCI，终端最终选择将UCI复用在载波4的PUSCH上进行传输，丢弃载波1上时隙n中的PUCCH。
2)多个PUSCH中，如果不存在子载波间隔和PUCCH载波相同的PUSCH，则选择子载波间隔最小的PUSCH。
例如，假设基站为终端配置了三个载波，其中载波1的子载波间隔配置为15kHz，载波2的子载波间隔配置为60kHz，载波3的子载波间隔配置为30kHz。其中载波1为PUCCH的传输载波，当在载波1的时隙n中存在PUCCH传输时，如果同时基站调度了载波2和载波3上的PUSCH传输，如图4所示，在载波2的时隙4n、4n+1、4n+2、4n+3和载波3的时隙2n、2n+1中均存在PUSCH。由于载波3为PUSCH载波中子载波间隔配置最小的载波，终端选择将UCI复用在载波3的PUSCH上进行传输，丢弃载波1上时隙n中的PUCCH。
3)多个PUSCH中，如果不存在子载波间隔和PUCCH载波相同的PUSCH， 则：
3.1)如果多个PUSCH中包含用于传输A-CSI的PUSCH，则选择用于传输A-CSI的PUSCH；或者，
3.2)如果多个PUSCH中同时存在具有对应PDCCH的PUSCH和没有对应PDCCH的PUSCH，则选择具有对应PDCCH的PUSCH；或者，
3.3)如果多个PUSCH中存在多个具有对应PDCCH的PUSCH和多个没有对应PDCCH的PUSCH，按照PUSCH的载波的编号顺序，选择编号最小的载波上的PUSCH；或者，
3.4)如果在同一个载波上有多个时分复用的PUSCH和同一个PUCCH重叠，则选择起始传输符号最早的PUSCH。
4)选择子载波间隔最小的PUSCH载波。
例如，假设基站为终端配置了三个载波，其中载波1的子载波间隔配置为15kHz，载波2的子载波间隔配置为60kHz，载波3的子载波间隔配置为30kHz。如果同时基站调度了载波2和载波3上的PUSCH传输，在载波2的时隙4n、4n+1、4n+2、4n+3和载波3的时隙2n、2n+1中均存在PUSCH。由于载波3为PUSCH载波中子载波间隔配置最小的载波，终端选择将UCI复用在载波3的PUSCH上进行传输。
本公开的实施例所述的上行控制信息的发送方法中，步骤11选择PUSCH后还可以进一步包括：
如果选择出的PUSCH包括多个子载波间隔相同的PUSCH，则在所述多个子载波间隔相同的PUSCH中，选择一个PUSCH。
其中，在所述多个子载波间隔相同的PUSCH中，选择一个PUSCH时，可以利用上述方式3)实现。
本公开的上述实施例给出了一种UCI在PUSCH上的传输方法，如果PUCCH和多个PUSCH在时间上重叠，且多个PUSCH载波中至少存在两种不同的子载波间隔，优先选择子载波间隔和PUCCH相同或者子载波间隔较小的PUSCH载波传输UCI信息，从而避免UCI在子载波间隔较大载波传输导致传输性能下降的情况。
