发送UCI的方法及用户终端
相关申请的交叉引用
本申请主张在2018年2月9日在中国提交的中国专利申请号No.201810136167.9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，特别是指一种发送UCI的方法及用户终端。
背景技术
长期演进(Long Term Evolution，LTE)系统中，当用户终端(User Equipment，UE)在某一个子帧内同时需要发送上行数据与上行控制信令(uplink control information，UCI)时，UE可以在上行数据中携带上行控制信令，从而降低功率峰均比。
LTE系统还支持载波汇聚(Carrier Aggregation，CA)技术，UE可以在多个上行载波发送上行数据。当在一个子帧内多个上行载波同时存在物理上行共享信道(physical uplink shared channel，PUSCH)发送，且UE需要在该子帧内发送UCI时，UE选择其中一个PUSCH携带UCI，即，在选择的PUSCH中复用UCI并发送。UE简单根据载波的下标选择PUSCH，即复用最小的载波下标的PUSCH以传输UCI。
新空口(New Radio，NR)系统也支持CA以及在PUSCH中复用UCI的设计。但一方面，NR系统中支持灵活的帧结构，不同上行载波的数值特征(numerology)可以不同。另一方面，NR系统中支持灵活动态的物理上行控制信道(physical uplink control channel，PUCCH)结构，PUCCH可以是1～2个符号的短PUCCH格式，或4～14符号的长PUCCH格式。因此，LTE简单的载波选择技术不适用于NR。此外，NR还可以为UE配置免授权(grant-free)或配置调度(configured scheduling)的PUSCH以支持高可靠低时延(Ultra-reliable low latency communication，URLLC)业务，简单沿用LTE的载波选择技术会增加免授权或配置调度的PUSCH的处理复杂度。
发明内容
本公开要解决的技术问题是提供一种发送UCI的方法及用户终端，能够支持UE在有多个候选的PUSCH发送时选择最好的PUSCH携带UCI，降低系统的处理时延，降低UE的峰均比。
为解决上述技术问题，本公开的实施例提供技术方案如下：
第一方面，本公开的一些实施例提供了一种发送UCI的方法，包括：
在物理上行控制信道PUCCH与物理上行共享信道PUSCH在时间上存在重叠时，根据以下参数的至少一种选择PUSCH携带UCI并进行发送：

上行载波的数值特征。
第二方面，本公开的一些实施例提供了一种用户终端，包括：

本公开的实施例具有以下有益效果：
上述方案中，根据上行数据调度类型以及上行载波的数值特征来选择合适载波上的PUSCH携带UCI进行发送，能够支持UE在有多个候选的PUSCH发送时选择最好的PUSCH携带UCI，一方面可以降低上行传输时延，提高UCI的传输可靠度，降低UE端编码以及复用PUSCH的复杂度，降低UE的 峰均比。另一方面，也避免UCI复用对URLLC业务的影响，降低URLLC的上行数据的处理时延，避免基站对URLLC的上行数据的盲检，并保持URLLC的上行数据的码率不下降。

图2-图11为本公开的一些实施例的选择PUSCH的示意图；
图12为本公开的一些实施例的用户终端的结构框图；以及
图13为本公开的一些实施例的用户终端的组成示意图。
具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完成地描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的实施例提供一种发送UCI的方法及用户终端，能够支持UE在有多个候选的PUSCH发送时选择最好的PUSCH携带UCI，降低系统的处理时延，降低UE的峰均比。
本公开的一些实施例提供了一种发送UCI的方法，如图1所示，包括：
步骤101：在PUCCH与PUSCH在时间上存在重叠时，根据以下参数的至少一种选择PUSCH携带UCI并进行发送：
上行数据调度类型；
上行载波的数值特征。
其中，上行载波的数值特征也指子载波间隔和符号长度。本公开的一些实施例提供了一种复用PUSCH发送UCI的方法，具体可以根据上行数据调度类型、上行载波的数值特征(numerology)、子载波间隔(subcarrier spacing，SCS)或符号长度(symbol duration)选择合适载波上的PUSCH携带UCI并 发送。
本公开的一些实施例中，根据上行数据调度类型以及上行载波的数值特征来选择合适载波上的PUSCH携带UCI进行发送，能够支持UE在有多个候选的PUSCH发送时选择最好的PUSCH携带UCI，一方面可以降低上行传输时延，提高UCI的传输可靠度，降低UE端编码以及复用PUSCH的复杂度，降低UE的峰均比。另一方面，也避免UCI复用对URLLC业务的影响，降低URLLC的上行数据的处理时延，避免基站对URLLC的上行数据的盲检，并保持URLLC的上行数据的码率不下降。
具体来说，当UE配置了多个服务小区(serving cell)或上行载波(carrier)，或补充上行载波(supplementary uplink，SUL)，且PUCCH与PUSCH不同时发送，如果UE需要发送PUCCH，UE需要选择PUSCH来复用PUCCH发送UCI。
首先，需要在PUCCH发送的时隙(slot)内，判断PUCCH与PUSCH是否重叠，所述根据以下参数的至少一种选择PUSCH携带UCI并进行发送的步骤之前，所述方法还包括：
在PUCCH发送的时隙内，判断PUCCH与PUSCH在时间上是否存在重叠。
判断方法包括有：
方法一：基于符号判决重叠
把PUSCH以及PUCCH映射到参考载波上，并根据数值特征的不同对PUSCH以及PUCCH进行缩放，可选PUCCH所在载波为参考载波。
例如，PUCCH的SCS是15kHz，PUSCH的SCS是30kHz。以PUCCH所在载波为参考载波，则一个14符号长度的PUSCH在PUCCH所在载波上的映射为7符号长度。
图2所示为将SCS是30kHz、时隙标识(slot index)是1的PUSCH映射到SCS是15kHz、slot index是0的PUCCH所在载波上示意图，其中，slot index是时隙编号，symbol index是符号编号。
在把PUSCH以及PUCCH映射到参考载波上后，可以根据PUCCH的符 号的起始位置以及长度，映射后的PUSCH的符号的起始位置以及长度，判断PUCCH与PUSCH在时间上是否存在重叠。
方法二：基于slot判决重叠
本方法是根据PUCCH的numerology，把PUCCH进行缩放并映射到每个PUSCH所在载波上，如果映射后的PUCCH的符号的起始位置以及长度，与PUSCH所在的slot部分或完全重叠，则认为两者存在重叠。
其中，判断方法的选择可以是协议预定义，或通过高层参数配置。
在判断PUCCH与PUSCH是否重叠后，如果PUCCH与PUSCH不存在重叠，则UCI继续在PUCCH上发送。如果PUCCH与PUSCH在时间上存在重叠，则按照下面方法选择PUSCH携带UCI进行发送。
(1)所述上行数据调度类型包括由下行控制信息DCI调度，如果存在一个PUSCH由下行控制信息(downlink control information，DCI)调度，且该DCI指示了非周期信道状态信息(aperiodic channel state information，A-CSI)或半静态信道状态信息(semi-persistent channel state information，SP-CSI)上报，则复用该DCI调度的PUSCH，选择所述PUSCH携带UCI并进行发送。
(2)所述上行载波的数值特征包括开始传输的时间点，比较映射后的PUSCH与PUCCH的起始符号位置。
如果存在PUSCH的起始符号下标大于或等于PUCCH的起始符号下标，则复用该PUSCH进行UCI的传输。即在PUSCH开始传输的时间点与PUCCH开始传输的时间点相同或PUSCH开始传输的时间点在PUCCH开始传输的时间点之后时，选择复用所述PUSCH发送UCI。
(3)所述上行数据调度类型包括免授权或配置调度，在不存在PUSCH的起始符号下标大于或等于PUCCH的起始符号下标时，即在PUSCH开始传输的时间点在PUCCH开始传输的时间点之前时，如果重叠的PUSCH至少有一个是免授权(grant-free)或配置调度(configured scheduling)的PUSCH，则打孔(puncture)PUCCH重叠的部分，或丢弃整个UCI；否则，传输该PUCCH，并不传输PUSCH重叠的部分(例如打孔或速率匹配)或丢弃整个PUSCH。
(4)如果确定复用PUSCH来发送UCI，且存在多个与PUCCH在时间 上重叠的PUSCH可以用于携带并发送UCI，根据以下方式中的至少一种选择携带UCI的PUSCH：
a.优先选择非grant-free或configured scheduling PUSCH，即选择免授权或配置调度的PUSCH以外的PUSCH携带UCI。
b.在所述上行载波的数值特征还包括UCI的码率时，根据网络配置或指示的β偏移值(Beta offset)的权重选择携带UCI后UCI的码率最低的PUSCH携带UCI。
c.在所述上行载波的数值特征还包括结束传输的时间点时，根据映射后的PUSCH与PUCCH的结束符号下标，选择其中结束符号下标最小的PUSCH进行UCI的传输，即选择结束传输的时间点最早的PUSCH携带UCI。
d.如果存在重叠的PUSCH在PUCCH所在的小区或载波上传输，则复用在该PUSCH上传输UCI。
e.在所述上行载波的数值特征还包括小区或载波的下标时，选择下标最小的小区或载波上的PUSCH，复用该PUSCH进行UCI的传输；
f.在所述上行载波的数值特征还包括PUSCH的数据部分等效码率和控制比特时，选择携带UCI后PUSCH的数据部分等效码率最低或控制比特开销最少的PUSCH携带UCI。
g.在所述上行载波的数值特征还包括结束传输的时间点，且存在多个与PUCCH重叠的PUSCH能够用于携带UCI时，选择开始传输的时间点与PUCCH开始传输的时间点相同，且结束传输的时间点最早的PUSCH携带UCI。
下面结合具体的示例例对本公开的发送UCI的方法进行详细介绍：
具体示例一
如图3所示为一个长PUCCH格式与PUSCH同时存在的例子，根据上述判断PUCCH与PUSCH是否重叠的方式可以判断，其中的PUSCH-3与PUCCH不重叠，而PUSCH-1与PUSCH-2均与PUCCH重叠。传输时，PUSCH-3单独传输，PUCCH不传输，UCI复用在PUSCH-1上传输。
如图4所示为一个短PUCCH格式与PUSCH同时存在的例子，根据上述 判断PUCCH与PUSCH是否重叠的方式可以判断，其中的PUSCH-2与PUCCH重叠，而PUSCH-1与PUSCH-3均与PUCCH不重叠。传输时，PUSCH-1与PUSCH-3单独传输，PUCCH不传输，UCI复用在PUSCH-2上传输。
具体示例二
如图5所示，当PUCCH与多个PUSCH重叠时，PUCCH不传输，选择复用PUSCH-2来传输UCI，因为PUSCH-2的起始符号下标等于PUCCH的起始符号下标，且结束符号下标小于PUSCH-1。这样可以使得UCI的传输时延较低，从而可以降低空口的传输时延。
具体示例三
如图6所示，如果PUSCH-2配置为configured scheduling PUSCH，用于传输低时延高可靠(Ultra Reliable Low Latency Communications，URLLC)业务，则优先选择非configured scheduling的PUSCH-1，复用PUSCH-1进行UCI的传输。这样，可以避免复用PUSCH-2传输UCI对URLLC业务的影响，降低URLLC的上行数据的处理时延，避免网络侧设备比如基站对URLLC的上行数据的盲检，并保持URLLC的上行数据的码率不下降。
具体示例四
如图7所示，当PUCCH与多个PUSCH重叠，其中PUSCH-2是由DCI调度，且该DCI指示UE触发A-CSI上报，则选择复用该DCI调度的PUSCH-2传输UCI。
具体示例五
如图8所示，当PUCCH与多个PUSCH重叠，且经映射后重叠的PUSCH的起始符号下标小于PUCCH的起始符号下标，则丢弃该重叠的PUSCH。
如图9所示，如果重叠的PUSCH-2是configured scheduling的PUSCH，则丢弃该UCI。
具体示例六
如图10所示，当PUCCH与多个PUSCH重叠，根据网络侧设备指示的β偏移值(Beta offset)的权重，选择复用PUSCH传输UCI后UCI的码率最 低的PUSCH，即PUSCH-2来传输UCI。这样可以保证UCI的传输可靠性。
具体示例七
如图11所示，当PUCCH与多个PUSCH重叠，且经过上述多种条件选择后，仍然存在多个候选的PUSCH，则选择下标最小的小区或载波上的PUSCH，即复用PUSCH-1来传输UCI，这样可以降低UE端编码以及复用PUSCH的复杂度。
