Description

上行控制信息的发送及接收方法和装置
本申请要求于2017年10月26日提交中国专利局、申请号为201711022583.8、申请名称为“上行控制信息的传输方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种上行控制信息的传输方法和装置。
背景技术
在无线通信系统中，终端通常通过物理上行控制信道(Physical Uplink Control Channel；PUCCH)传输上行控制信息(Uplink Control Information；UCI)，通过物理上行共享信道(Physical Uplink Shared Channel；PUSCH)进行数据的传输。当基站配置终端关闭PUCCH和PUSCH同时传输功能，或者终端没有在一个时刻同时传输PUCCH和PUSCH的功能时，则在该时刻该终端只传输PUSCH，而PUCCH中的UCI则嵌入到PUSCH中与数据一起传输。
在高级长期演进(Long Term Evolution-Advanced，LTE-A)系统中，由于PUCCH的传输时长固定为1ms，且频域上的子载波间隔也为固定值，终端在将PUCCH中的UCI复用在PUSCH中与数据一起传输时，数据将围着UCI进行速率匹配，或者UCI将数据打孔，具体地，UCI中的信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、预编码类型指示(Precoding Type Indication，PTI)将从高频部分横向生长，确认/否定确认(ACKnowledgement/Negative ACKnowledgement；A/N)附着在解调参考信号(Demodulation Reference Signal；DMRS)两边的符号上，再往外是秩指示(Rank Indicator，RI)。
然而，在新空口(New Radio；NR)中，PUCCH的传输时长不固定，且NR中有多种子载波间隔，导致单位符号长度也有多种，因此，如何将UCI映射到PUSCH中，以保证上行控制信息能够合理的通过PUSCH发送，是目前亟待解决的技术问题。
发明内容
本申请实施例提供一种上行控制信息的传输方法和装置，通过将上行控制信息合理的映射到PUSCH中，并能够合理的通过PUSCH发送UCI。
本申请第一方面提供一种上行控制信息的传输方法，包括：确定映射影响因素，所述映射影响因素用于指示物理上行共享信道PUSCH或所述上行控制信息；根据所述映射影响因素，将所述上行控制信息映射到所述PUSCH中；将所述PUSCH发送给基站。
在本方案中，UCI中包括信道状态指示(Channel State Indicator，CSI)、确认/ 否定确认(ACKnowledgement/Negative ACKnowledgement，A/N)、调度请求(Scheduling Request，SR)、以及一些波束相关的指示信息等多种信息，其中CSI又包括信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、预编码类型指示(Precoding Type Indication，PTI)和秩指示(Rank Indicator，RI)等。
在上述方案中，由于终端设备在确定出映射影响因素之后，将根据不同的映射影响因素，按照不同的方式将上行控制信息映射到PUSCH中，由此，终端可以将上行控制信息UCI合理的映射到PUSCH中，并能够合理的通过PUSCH发送UCI。
可选地，所述映射影响因素包括如下信息中的至少一个：配置给所述上行控制信息的资源的子载波间隔、所述PUSCH的子载波间隔、配置给所述上行控制信息的资源的时域位置、所述PUSCH的时域位置、配置给所述上行控制信息的资源的频域位置、所述PUSCH的频域位置、所述上行控制信息的传输时延、终端的处理时延、所述PUSCH的码块组CBG信息、所述PUSCH的跳频情况、所述PUSCH的调制阶数、所述PUSCH的码率、所述PUSCH中数据的重传信息、所述PUSCH中数据包的大小、配置给所述上行控制信息的资源和PUSCH是否在同一个载波或同一个带宽部分、所述PUSCH的参考信号的位置、所述上行控制信息的定时。
可选地，所述映射影响因素包括配置给所述上行控制信息的资源的子载波间隔和所述PUSCH的子载波间隔；所述上行控制信息映射到能够覆盖所述上行控制信息的时域资源对应的PUSCH的时域资源上。
在本方案中，当配置给UCI的资源的子载波间隔和PUSCH的子载波间隔不同时，比如配置给UCI的资源和PUSCH位于不同的载波上(不支持在一个载波上给UE有多种子载波间隔不同的激活的带宽部分)，则配置给UCI的资源的符号与PUSCH的符号的长短将不一样。此时，在映射UCI时，可以将UCI映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上，由此可以保证UCI能够合理的映射到PUSCH，保证了UCI的正常传输。
可选地，所述映射影响因素包括配置给所述上行控制信息的资源的时域位置和所述PUSCH的时域位置，所述上行控制信息映射到配置给所述上行控制信息的资源和所述PUSCH重叠的时域资源上。
其中，配置给UCI的资源和PUSCH可以全部重叠，也可以部分重叠。当部分重叠，且配置给UCI的资源早于PUSCH时，可以将UCI映射在PUSCH中最早的符号上，这样，可以尽可能的降低UCI的传输时延。当部分重叠，且配置给UCI的资源晚于PUSCH，可以将UCI映射在PUSCH中最晚的符号上，这样，能够确保将UCI映射在PUSCH中。
可选地，所述上行控制信息映射在配置给所述上行控制信息的资源和所述PUSCH重叠的第一个符号上或者基站配置的符号上。
在本方案中，当配置给UCI的资源和PUSCH具有重叠的时域资源时，可以将UCI映射在重叠的第一个符号上，这样，传输UCI的时延将更低。
可选地，所述上行控制信息映射到所述PUSCH的位置对应的符号不早于配置给所述上行控制信息的资源的起始符号，或不晚于配置给所述上行控制信息的资源的最 后一个符号。
在本方案中，配置给UCI的资源的时域位置包括该资源的起始符号、终止符号以及符号个数，PUSCH的时域位置包括PUSCH的起始符号、终止符号以及符号个数。
可选地，所述映射影响因素包括配置给所述上行控制信息的资源的频域位置和所述PUSCH的频域位置，所述上行控制信息映射到配置给所述上行控制信息的资源和所述PUSCH重叠的频域资源上。
在本方案中，配置给UCI的资源的频域位置和PUSCH的频域位置均包括起始资源块(Resource Block；RB)、终止RB和RB个数，终端可以根据配置给UCI的资源的起始RB、终止RB和RB个数以及PUSCH的起始RB、终止RB和RB个数，确定配置给UCI的资源和PUSCH重叠的频域资源，并将UCI映射到重叠的频域资源上。
可选地，所述映射影响因素包括所述上行控制信息的传输时延，所述上行控制信息映射的时域位置满足所述上行控制信息的传输时延。
在本方案中，UCI中包括CSI、A/N和SR等多种信息，这些信息虽然均在同一块资源中进行复用，但是却有各自的传输时延，即有各自的定时。终端在进行UCI的映射时，将UCI映射到PUSCH的时域位置将不晚于CSI、A/N和SR各自对应的传输时延的最小值，由此可以保证映射后的UCI的发送时延。
可选地，所述映射影响因素包括所述终端的处理时延，所述上行控制信息映射的时域位置，大于所述终端的处理时延。
在本方案中，UCI映射的时域位置大于终端的处理时延，这样可以使UE能够有足够的时间处理UCI，保证了UCI的正常发送。
可选地，所述映射影响因素包括所述PUSCH的码块组CBG信息，所述上行控制信息映射到所述PUSCH中处于配置给所述上行控制信息的时域资源范围内的所述CBG中。
在本方案中，将UCI映射到PUSCH中处于配置给UCI的时域资源范围内的CBG中，这样可以减少需要重传的CBG的数量。
可选地，所述映射影响因素包括所述PUSCH的跳频情况，所述上行控制信息分散映射到所述PUSCH中的每个跳频中，或者，所述上行控制信息集中映射到所述PUSCH中的一个跳频中。
在本方案中，如果PUSCH的数据有频域跳频，则UCI可以分散映射到PUSCH中的每个跳频中，这样可以获得频率分集增益，另外，UCI也可以集中映射在PUSCH中的少数跳频中，例如可以集中映射在一个跳频中，以降低UCI解调的复杂度。
可选地，所述映射影响因素包括所述配置给所述上行控制信息的资源和PUSCH是否在同一个载波或同一个带宽部分，若所述配置给所述上行控制信息的资源和PUSCH在同一个载波或同一个带宽部分，所述上行控制信息在所述PUSCH中以频域优先的方式映射；若所述配置给所述上行控制信息的资源和PUSCH不在同一个载波或同一个带宽部分，所述上行控制信息在所述PUSCH中以时域优先的方式映射。
在本方案中，若配置给UCI的资源和PUSCH在同一个载波或同一个BWP中，则子载波间隔(Sub Carrier Spacing；SCS)相同的可能性较大，此时，可以将UCI在PUSCH中以频域优先的方式映射，如果配置给UCI的资源和PUSCH不在同一个载波或同一 个BWP中，则SCS不同的可能性较大，此时，可以将UCI在PUSCH中以时域优先的方式映射。
可选地，若所述PUSCH中包括参考信号，所述上行控制信息映射到所述PUSCH中不与所述参考信号重叠的位置，或者，所述上行控制信息的比特数小于预设阈值时，所述上行控制信息映射到所述PUSCH中的所述参考信号上，所述参考信号包括如下信号中的至少一种：解调参考信号DMRS、侦听参考信号SRS、信道状态信息参考信号CSI-RS或相位跟踪参考信号PT-RS。
在本方案中，在进行UCI映射时，若PUSCH中包括DMRS、SRS、CSI-RS或PT-RS中的至少一个时，则可以避开DMRS、SRS、CSI-RS或PT-RS的位置，即映射到PUSCH中不与上述参考信号重叠的位置。另外，若UCI的比特数较少，如小于2比特时，则可以将UCI直接映射到PUSCH中的上述参考信号上，如循环移位(Cyclic Shift；CS)或正交掩码(Orthogonal Cover Code；OCC)或梳齿Comb携带比特。
可选地，所述上行控制信息包括至少两部分，各部分映射到所述PUSCH中的映射方式不同，或各部分映射到不同的时频资源。
在本方案中，可以将UCI分为多个部分，其中，每个部分在映射到PUSCH中时，可以独立的选择对应的映射方式，以及映射到哪部分时频资源。
可选地，各部分中包含的信息类型不同。
在本方案中，UCI中包括有CSI、A/N和SR等信息，若UCI包括至少两部分信息时，各部分中包括的信息类型不同。
可选地，上行控制信息的映射方式为集中映射方式或分散映射方式；或者上行控制信息的映射方式为上行控制信息对数据进行打孔或数据围绕所述上行控制信息做速率匹配。
在本方案中，UCI在映射到PUSCH中时，可以采用UCI对数据进行打孔的方式进行集中映射或者分散映射，也可以采用数据围绕UCI做速率匹配的方式进行集中映射或者分散映射。
可选地，所述映射影响因素为所述基站配置给终端或所述终端上报给所述基站的。
在本方案中，配置给UCI的资源的子载波间隔、PUSCH的子载波间隔、配置给UCI的资源的时域位置、PUSCH的时域位置、配置给UCI的资源的频域位置、PUSCH的频域位置、UCI的传输时延、PUSCH的CBG信息、PUSCH的跳频情况、PUSCH的调制阶数、PUSCH的码率、PUSCH中数据的重传信息、PUSCH中数据包的大小、配置给UCI的资源和PUSCH是否在同一个载波或同一个带宽部分、PUSCH的参考信号的位置或UCI的定时是由基站配置给终端的，终端的处理时延是由终端上报给基站的。
本申请第二方面提供一种上行控制信息的传输方法，包括：接收终端发送的物理上行共享信道PUSCH，所述PUSCH中包含有上行控制信息；根据映射影响因素，获取所述PUSCH中包含的所述上行控制信息，所述映射影响因素用于指示物理上行共享信道PUSCH或所述上行控制信息。
在本方案中，UCI中包括CSI、A/N、SR、以及一些波束相关的指示信息等多种信息，其中CSI又包括CQI、PMI、PTI和RI等。
在上述方案中，由于基站在接收到PUSCH后，可以根据映射影响因素，从PUSCH中获取到UCI，从而保证了UCI的正常传输。
可选地，所述映射影响因素包括如下信息中的至少一个：配置给所述上行控制信息的资源的子载波间隔、所述PUSCH的子载波间隔、配置给所述上行控制信息的资源的时域位置、所述PUSCH的时域位置、配置给所述上行控制信息的资源的频域位置、所述PUSCH的频域位置、所述上行控制信息的传输时延、终端的处理时延、所述PUSCH的码块组CBG信息、所述PUSCH的跳频情况、所述PUSCH的调制阶数、所述PUSCH的码率、所述PUSCH中数据的重传信息、所述PUSCH中数据包的大小、配置给所述上行控制信息的资源和PUSCH是否在同一个载波或同一个带宽部分、所述PUSCH的参考信号的位置、或所述上行控制信息的定时。

具体实施方式
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2)基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station；BTS)，也可以是WCDMA中的基站(NodeB)，还可以是长期演进(Long Term Evolution；LTE)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本申请并不限定。
本领域技术人员可以理解，本申请实施例提供的上行控制信息的映射方法可以应用于第5代网络(5th Generation；5G)和下一代通信系统中。图1为NR系统的架构示意图，如图1所示，该系统包括终端10和基站20，其中，终端10例如可以为UE。其中，基站20向终端10传输数据的过程为下行传输，终端10向基站20传输数据的过程为上行传输。
在图1所示的系统架构的基础上，在5G NR中，引入了多种子载波间隔，基线为 15kHz，可以是15kHz*2 n，其中，n是整数，这样，从3.75、7.5直到480kHz，最多8种子载波间隔。对应的，也有多种符号长度和时隙长度。子帧长度固定为1毫秒，因而1个子帧中包含的时隙个数会随着子载波间隔的不同而不同。另外，在NR中，一个时隙可以由下行传输、保护间隔(Guard Period；GP)和上行传输等其中的至少一个组成；这样时隙的构成至少包括下面几种：下行(Downlink；DL)时隙(DL only slot)，下行中心时隙(DL centric slot),上行(Uplink；UL)中心时隙(UL centric slot)和上行时隙(UL only slot)等。不同的时隙构成包括的上行符号个数、下行符号个数或保护间隔符号个数不一定一样。
另外，时隙还可以有不同的时隙类型，不同的时隙类型包括的符号个数不一样，如迷你时隙(Mini slot)包含小于14个符号(如1个符号、2个符号、4个符号、7个符号等)，普通时隙(Slot)包含14个符号。当工作于高频场景时，衰落较严重，为了解决覆盖问题，在NR中，引入了时隙聚合技术，即可以将多个时隙分配给同一个UE用于传输数据，可以用于上行数据(PUSCH)调度，也可以用于下行数据(PDSCH)调度，还可以将这多个时隙用于UCI重复(PUCCH)。
在NR上行传输中，当一个时隙既有UCI需要传输也有数据需要传输时，会将UCI承载在PUSCH上与数据一起传输，由于PUCCH的传输时长不固定，且NR中有多种子载波间隔，导致单位符号长度也有多种，因此，终端将无法合理的把UCI映射到PUSCH中，因而也就无法合理的通过PUSCH发送上行控制信息。
本申请实施例考虑到这些情况，提出一种上行控制信息的映射方法，通过确定映射影响因素，并根据该映射影响因素，将上行控制信息映射到中，然后将PUSCH发送给基站，其中，映射影响因素用于指示PUSCH或上行控制信息。由于终端设备在确定出映射影响因素之后，将根据不同的映射影响因素，按照不同的方式将上行控制信息映射到PUSCH中，由此，终端可以将上行控制信息UCI合理的映射到PUSCH中，并能够合理的通过PUSCH发送UCI。
图2为本申请上行控制信息的映射方法实施例一的信令流程图。在上述图1所示系统架构的基础上，如图2所示，本实施例的方法可以包括：
步骤201、终端确定映射影响因素，该映射影响因素用于指示PUSCH或UCI。
在本实施例中，当基站配置终端关闭PUCCH和PUSCH同时传输功能，或者终端没有在一个时刻同时传输PUCCH和PUSCH的功能时，则在该时刻该终端将只传输PUSCH，而PUCCH中的UCI则嵌入到PUSCH中与数据一起传输。由于在NR中，PUCCH的传输时长不固定，且NR中有多种子载波间隔，导致单位符号长度也有多种，因此，UCI映射到PUSCH中时，将会存在多种映射影响因素影响UCI的映射位置，其中，映射影响因素用于指示PUSCH或UCI。
具体地，UCI中包括信道状态指示(Channel State Indicator，CSI)、确认/否定确认(ACKnowledgement/Negative ACKnowledgement，A/N)、调度请求(Scheduling Request，SR)、以及一些波束相关的指示信息等多种信息，其中CSI又包括信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、预编码类型指示(Precoding Type Indication，PTI)、秩指示(Rank Indicator，RI)等。
在一种可能的实现方式中，映射影响因素包括如下信息中的至少一个：配置给UCI的资源的子载波间隔、PUSCH的子载波间隔、配置给UCI的资源的时域位置、PUSCH的时域位置、配置给UCI的资源的频域位置、PUSCH的频域位置、UCI的传输时延、终端的处理时延、PUSCH的码块组(Code Block Group；CBG)信息、PUSCH的跳频情况、PUSCH的调制阶数、PUSCH的码率、PUSCH中数据的重传信息、PUSCH中数据包的大小、配置给上行控制信息的资源和PUSCH是否在同一个载波或同一个带宽部分(BandWidth Part；BWP)、PUSCH的参考信号的位置、上行控制信息的定时。
配置给UCI的资源指基站配置给终端用于发送UCI的PUCCH的资源，可以是只占一个或两个符号的短PUCCH，也可以是占4-14个符号的长PUCCH；可以是占一个RB的PUCCH，也可以是占多个RB的PUCCH。只是由于该时刻同时出现上行数据调度PUSCH，而终端没有在一个时刻同时传输PUCCH和PUSCH的功能，或终端有在一个时刻同时传输PUCCH和PUSCH的功能但基站配置终端关闭PUCCH和PUSCH同时传输功能，因而终端实际并未发送PUCCH信道。
在一种可能的实现方式中，映射影响因素为基站配置给终端或终端上报给基站的。其中，配置给UCI的资源的子载波间隔、PUSCH的子载波间隔、配置给UCI的资源的时域位置、PUSCH的时域位置、配置给UCI的资源的频域位置、PUSCH的频域位置、UCI的传输时延、PUSCH的CBG信息、PUSCH的跳频情况、PUSCH的调制阶数、PUSCH的码率、PUSCH中数据的重传信息、PUSCH中数据包的大小、配置给UCI的资源和PUSCH是否在同一个载波或同一个带宽部分、PUSCH的参考信号的位置或UCI的定时是由基站配置给终端的，终端的处理时延是由终端上报给基站的。
步骤202、终端根据映射影响因素，将UCI映射到PUSCH中。
在本实施例中，终端在确定出映射影响因素之后，可以根据不同的映射影响因素，确定出不同的映射方式，并根据不同的映射方式将UCI映射到PUSCH中。
在本实施例中，终端在确定出映射影响因素之后，可以根据不同的映射影响因素，确定出不同的映射资源，并将UCI映射到PUSCH的对应映射资源中。
下面，将对终端根据不同的映射影响因素，将UCI映射到PUSCH中的具体方式进行详细说明。
可选地，若映射影响因素包括配置给UCI的资源的子载波间隔和PUSCH的子载波间隔，则UCI映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上。
具体地，在发送UCI之前，基站会给终端配置承载UCI的资源，例如可以配置PUCCH资源，只是刚好PUCCH和PUSCH出现在了同一个时隙，且UE没有能力同时传输PUCCH和PUSCH或基站不允许能PUCCH和PUSCH同时传输。但是，对于终端来说，终端是可以获知承载UCI的资源的。
当配置给UCI的资源的子载波间隔和PUSCH的子载波间隔不同时，比如配置给UCI的资源和PUSCH位于不同的载波上(不支持在一个载波上给UE有多种子载波间隔不同的激活的带宽部分BWP)，则配置给UCI的资源的符号与PUSCH的符号的长短将不一样。此时，在映射UCI时，可以将UCI映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上。
举例来说，图3a为配置给UCI的资源的子载波间隔和PUSCH的子载波间隔的一 示意图，如图3a所示，当配置给UCI的资源的子载波间隔小于PUSCH的子载波间隔，即配置给UCI的资源的符号大于PUSCH的符号，以15kHz和30kHz为例，配置给UCI的资源所在载波的符号长度是PUSCH所在载波的符号长度的两倍，在映射UCI时，可以将UCI映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上，即将UCI映射到配置给UCI的资源所在符号对应的PUSCH的符号上。如图3a所示，可以将UCI同时映射到与配置给UCI的资源的符号重叠的两个PUSCH中，如第12个符号和第13个符号上。另外，但由于一般配置给UCI的资源的带宽比PUSCH小，因而可能只需要将UCI映射到PUSCH中的一个符号上即可，此时可以在与PUCCH符号重叠的两个PUSCH符号中选一部分符号映射UCI。在一种可能的实现方式中，可以选择前面一个符号，如第12个符号上，这样，传输UCI的时延将更低。当然，也可以是基站确定出重叠的符号中哪些符号用于承载UCI后，将确定出的结果通知给终端，终端将UCI映射到基站确定出的符号上。
图3b为配置给UCI的资源的子载波间隔和PUSCH的子载波间隔的另一示意图，如图3b所示，当配置给UCI的资源的子载波间隔大于PUSCH的子载波间隔，即配置给UCI的资源的符号小于PUSCH的符号，以30kHz和15kHz为例，配置给UCI的资源所在载波的符号长度是PUSCH所在载波的符号长度的一半，在映射UCI时，可以将UCI映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上，即将UCI映射到配置给UCI的资源所在符号对应的PUSCH的符号上。如图3b所示，可以将UCI映射到与配置给UCI的资源的符号重叠的PUSCH的符号中，此时与配置给UCI的资源的符号重叠的可能是一个或多个更长PUSCH符号，如果重叠的只有一个符号，则选择该符号，并将UCI映射到该符号上。如果重叠的有多个符号，如图3b中配置给UCI的资源占的两个符号分别对应了PUSCH所占时隙的第12个和第13个符号的一半，此时，可以将UCI同时映射在这两个符号上，也可以选择前面一个符号，这样，传输UCI的时延将更低。当然，还可以是基站确定出重叠的符号中哪些符号用于承载UCI后，将确定出的结果通知给终端，终端将UCI映射到基站确定出的符号上。
在本实施例中，在映射影响因素包括配置给UCI的资源的子载波间隔和PUSCH的子载波间隔时，UCI将映射到能够覆盖UCI的时域资源对应的PUSCH的时域资源上，由此可以保证UCI能够合理的映射到PUSCH，保证了UCI的正常传输。
可选地，若映射影响因素包括配置给UCI的资源的时域位置和PUSCH的时域位置，UCI映射到配置给UCI的资源和PUSCH重叠的时域资源上。
具体地，当配置给UCI的资源和PUSCH具有重叠的时域资源时，则将UCI映射到配置给UCI的资源和PUSCH重叠的时域资源上。其中，配置给UCI的资源和PUSCH可以全部重叠，也可以部分重叠。
举例来说，图4a为配置给UCI的资源和PUSCH的一示意图，如图4a所示，配置给UCI的资源和PUSCH部分重叠，且配置给UCI的资源早于PUSCH，则可以将UCI映射在配置给UCI的资源和PUSCH重叠的符号上。在一种可能的实现方式中，可以将UCI映射在PUSCH中最早的符号上，这样，可以尽可能的降低UCI的传输时延。
图4b为配置给UCI的资源和PUSCH的另一示意图，如图4b所示，配置给UCI 的资源和PUSCH部分重叠，且配置给UCI的资源晚于PUSCH，则可以将UCI映射在配置给UCI的资源和PUSCH重叠的符号上。在一种可能的实现方式中，可以将UCI映射在PUSCH中最晚的符号上，这样，能够确保将UCI映射在PUSCH中。
在一种可能的实现方式中，UCI映射在配置给UCI的资源和PUSCH重叠的第一个符号上或者基站配置的符号上。
具体地，当配置给UCI的资源和PUSCH具有重叠的时域资源时，可以将UCI映射在重叠的第一个符号上，这样，传输UCI的时延将更低。另外，还可以是基站确定出重叠的符号中哪些符号用于承载UCI后，将确定出的结果通知给终端，终端将UCI映射到基站确定出的符号上。
在一种可能的实现方式中，UCI映射到PUSCH的位置对应的符号不早于配置给UCI的资源的起始符号，或不晚于配置给UCI的资源的最后一个符号。
具体地，配置给UCI的资源的时域位置包括该资源的起始符号、终止符号以及符号个数，PUSCH的时域位置包括PUSCH的起始符号、终止符号以及符号个数。在将UCI映射到PUSCH中，可以包括如下几种情况：(1)保证UCI映射到PUSCH的位置对应的符号不早于配置给UCI的资源的起始符号；(2)保证UCI映射到PUSCH的位置对应的符号不能晚于配置给UCI的资源的最后一个符号；(3)保证UCI映射到PUSCH的位置对应的符号不早于配置给UCI的资源的起始符号，且保证UCI映射到PUSCH的位置对应的符号不晚于配置给UCI的资源的最后一个符号。
可选地，若映射影响因素包括配置给UCI的资源的频域位置和PUSCH的频域位置，则UCI映射到配置给UCI的资源和PUSCH重叠的频域资源上。
具体地，配置给UCI的资源的频域位置和PUSCH的频域位置均包括起始资源块(Resource Block；RB)、终止RB和RB个数，终端可以根据配置给UCI的资源的起始RB、终止RB和RB个数以及PUSCH的起始RB、终止RB和RB个数，确定配置给UCI的资源和PUSCH重叠的频域资源，并将UCI映射到重叠的频域资源上。其中，UCI可以映射到所有重叠的频域资源上，也可以映射到部分重叠的频域资源上，例如：若配置给UCI的资源占的RB数较少，则可以将所有UCI集中映射到PUSCH的少数符号上，如集中映射到一个符号上。
另外，配置给UCI的资源和PUSCH的频域部分可以全部重叠，也可以部分重叠。
在本实施例中，在映射影响因素包括配置给UCI的资源的频域位置和PUSCH的频域位置时，UCI将映射到配置给UCI的资源和PUSCH重叠的频域资源上，由此可以保证UCI能够合理的映射到PUSCH，保证了UCI的正常传输。
可选地，若映射影响因素包括UCI的传输时延，UCI映射的时域位置满足UCI的传输时延。
具体地，UCI中包括CSI、A/N和SR等多种信息，这些信息虽然均在同一块资源中进行复用，但是却有各自的传输时延，即有各自的定时，例如：A/N的反馈定时取决于基站给终端配置的反馈时间K1的取值，CSI的传输时延和SR的传输时延均由基站确定后，会通知给终端。
终端在进行UCI的映射时，UCI映射到PUSCH的时域位置将不晚于UCI的传输时延，在实际应用中，将UCI映射到PUSCH的时域位置将不晚于CSI、A/N和SR各 自对应的传输时延的最小值，由此可以保证映射后的UCI的发送时延。
在本实施例中，在映射影响因素包括UCI的传输时延时，UCI映射的时域位置将满足UCI的传输时延，这样可以保证UCI的发送时延。
可选地，若映射影响因素包括终端的处理时延，UCI映射的时域位置大于终端的处理时延。
具体地，为了保证终端能够来得及准备UCI，在进行UCI映射时，UCI映射的时域位置需要大于终端的处理时延，即UCI映射到PUSCH的位置不早于终端的处理时延(收到PDSCH到反馈A/N的时间)，保证UCI映射的位置处于终端的处理时延范围内。
在本实施例中，在映射影响因素包括终端的处理时延时，UCI映射的时域位置大于终端的处理时延，这样可以使UE能够有足够的时间处理UCI，保证了UCI的正常发送。
可选地，若映射影响因素包括PUSCH的码块组(Code Block Group；CBG)信息，UCI映射到PUSCH中处于配置给UCI的时域资源范围内的CBG中。
具体地，当映射影响因素包括PUSCH的CBG信息时，UCI映射到PUSCH中处于配置给UCI的时域资源范围内的CBG中，在一种可能的实现方式中，可以映射到所有处于配置给UCI的时域资源范围内的CBG中，在另一可能的实现方式中，也可以集中映射在PUSCH中的某个或某些CBG中，这样可以减少需要重传的CBG的数量，例如可以映射在图3a和图3b中的CBG3中，也可以映射在CBG4中，或者还可以同时映射在CBG3和CBG4中。
在本实施例中，在映射影响因素包括PUSCH的码块组CBG信息时，UCI映射到PUSCH中处于配置给UCI的时域资源范围内的CBG中，这样可以减少需要重传的CBG的数量。
在另一可能的实现方式中，PUSCH的TB不拆分成CBG，或者说PUSCH只包含一个CBG。PUSCH是TB级传输还是CBG级传输可以用于确定UCI在PUSCH中的映射资源或映射方式，例如如果PUSCH是TB级传输，则数据围绕UCI进行速率匹配；如果PUSCH是CBG级传输，则UCI对数据进行打孔。因为如果PUSCH是CBG级传输，UCI对数据进行打孔只会影响部分CBG，如果出错需要重传的内容少；而如果PUSCH是TB级传输，UCI也对数据进行打孔则可以导致整个TB需要重传。
可选地，若映射影响因素包括PUSCH的跳频情况，UCI分散映射到PUSCH中的每个跳频中，或者，UCI集中映射到PUSCH中的一个跳频中。
具体地，如果PUSCH的数据有频域跳频，则UCI可以分散映射到PUSCH中的每个跳频中，这样可以获得频率分集增益，另外，UCI也可以集中映射在PUSCH中的少数跳频中，例如可以集中映射在一个跳频中，以降低UCI解调的复杂度。
可选地，若映射影响因素包括配置给UCI的资源和PUSCH是否在同一个载波或同一个BWP，若配置给UCI的资源和PUSCH在同一个载波或同一个BWP，UCI在PUSCH中以频域优先的方式映射；若配置给UCI的资源和PUSCH不在同一个载波或同一个BWP，UCI在PUSCH中以时域优先的方式映射。
具体地，若配置给UCI的资源和PUSCH在同一个载波或同一个BWP中，则子载 波间隔(Sub Carrier Spacing；SCS)相同的可能性较大，此时，可以将UCI在PUSCH中以频域优先的方式映射，如果配置给UCI的资源和PUSCH不在同一个载波或同一个BWP中，则SCS不同的可能性较大，此时，可以将UCI在PUSCH中以时域优先的方式映射。
可选地，若PUSCH中包括参考信号，UCI映射到PUSCH中不与参考信号重叠的位置，或者，上行控制信息的比特数小于预设阈值时，UCI映射到PUSCH中的参考信号上，其中，参考信号包括如下信号中的至少一种：解调参考信号(Demodulation Reference Signal；DMRS)、侦听参考信号(Sounding Reference Signal；SRS)、信道状态信息参考信号(Channel State Information-Reference Signal；CSI-RS)或相位跟踪参考信号(Phase Tracking Reference Signal；PT-RS)。
具体地，在进行UCI映射时，若PUSCH中包括DMRS、SRS、CSI-RS或PT-RS中的至少一个时，则可以避开DMRS、SRS、CSI-RS或PT-RS的位置，即映射到PUSCH中不与上述参考信号重叠的位置。另外，若UCI的比特数较少，如小于2比特时，则可以将UCI直接映射到PUSCH中的上述参考信号上，如循环移位(Cyclic Shift；CS)或正交掩码(Orthogonal Cover Code；OCC)或梳齿Comb携带比特。
另外，需要进行说明的是，若映射影响因素包括上述因素中的两个或两个以上时，在进行UCI映射时，将需要同时满足包括的映射影响因素对应的映射条件。例如：若映射影响因素包括配置给UCI的资源的时域位置和PUSCH的参考信号的位置时，在进行UCI的映射时，在将UCI映射到配置给UCI的资源和PUSCH重叠的时域资源上时，若遇到DMRS、SRS、CSI-RS或PT-RS信号时，则需要避开上述参考信号的位置，如继续向前或向后选取合适的符号，以映射UCI。
值得注意的是，在实际应用中，在映射影响因素同时包含上述的所有信息时，将UCI映射到PUSCH中后，UCI的性能最好。
可选地，UCI包括至少两部分，各部分映射到PUSCH中的映射方式不同，或各部分映射到不同的时频资源。
具体地，可以将UCI分为多个部分，其中，每个部分在映射到PUSCH中时，可以独立的选择对应的映射方式，以及映射到哪部分时频资源。例如：UCI包括第一部分和第二部分，其中，第一部分可以选择第一映射方式映射，第二部分可以选择第二映射方式进行映射，此时，第一部分和第二部分可以映射到同一个时频资源中，也可以映射到不同的时频资源中。另外，也可以是第一部分映射到第一时频资源中，第二部分映射到第二时频资源中，此时，第一部分和第二部分可以采用相同的映射方式进行映射，也可以采用不同的映射方式进行映射。
另外，在一种可能的实现方式中，UCI中各部分中包含的信息类型不同。具体地，UCI中包括有CSI、A/N和SR等信息，若UCI包括至少两部分信息时，各部分中包括的信息类型不同。例如：将UCI分成两部分信息，第一部分信息中包括A/N，第二部分信息中包括CSI和SR。又例如，将UCI分成三部分信息，第一部分信息中包括A/N，第二部分信息中包括CSI，第三部分信息中包括SR。
在一种可能的实现方式中，UCI中各部分包含的信息类型相同，如都是CSI，但各部分包含的信息内容不同。例如，将UCI分成两部分信息，第一部分信息中包括 CQI/PMI，第二部分信息中包括RI。又例如，将UCI分成两部分信息，第一部分信息中包括Type I CSI，第二部分信息中包括Type II CSI。其中Type 1CSI类似LTE的量化后的CQI/PMI，Type II CSI为信道矩阵信息。
可选地，UCI映射到PUSCH中的映射方式包括集中映射方式或分散映射方式，或者UCI的映射方式包括UCI对数据进行打孔或数据围绕UCI做速率匹配。
具体地，UCI在映射到PUSCH中时，可以采用UCI对数据进行打孔的方式进行集中映射或者分散映射，也可以采用数据围绕UCI做速率匹配的方式进行集中映射或者分散映射。
例如：在进行UCI的映射时，若映射影响因素包括PUSCH的调制阶数，则在调制阶数大于预设调制阶数时，将采用集中映射的方式将UCI映射到PUSCH中，在调制阶数不大于预设调制阶数时，将采用分散映射的方式将UCI映射到PUSCH中。此时，无论调制阶数是多少，终端可以采用UCI对数据进行打孔的方式映射UCI，也可以采用数据围绕UCI做速率匹配的方式映射UCI。
若映射影响因素包括PUSCH的码率，则在码率大于预设码率时，将采用集中映射的方式将UCI映射到PUSCH中，在码率不大于预设码率时，将采用分散映射的方式将UCI映射到PUSCH中。此时，无论码率是多少，终端可以采用UCI对数据进行打孔的方式映射UCI，也可以采用数据围绕UCI做速率匹配的方式映射UCI。
若映射影响因素包括PUSCH中数据的重传信息，则在PUSCH中的数据初传时，采用数据围绕UCI做速率匹配的方式将UCI映射到PUSCH中，在PUSCH中的数据重传时，采用UCI对数据进行打孔的方式将UCI映射到PUSCH中，此时，无论数据是否为重传，终端可以将UCI集中映射到PUSCH中，也可以将UCI分散映射到PUSCH中。
若映射影响因素包括PUSCH中数据包的大小，则在数据包的大小大于预设数值，即为大数据包时，采用UCI对数据进行打孔的方式将UCI映射到PUSCH中，在数据包的大小不大于预设数值，即为小数据包时，采用数据围绕UCI做速率匹配的方式将UCI映射到PUSCH中，此时，无论数据包的大小为多少，终端可以将UCI集中映射到PUSCH中，也可以将UCI分散映射到PUSCH中。
另外，终端获知要反馈的比特数的时间早于实际反馈A/N的时间，可以提前做速率匹配。
步骤203、终端将PUSCH发送给基站。
在本实施例中，终端在将UCI映射到PUSCH中后，则将映射有UCI的PUSCH发送给基站。
步骤204、基站根据映射影响因素，获取PUSCH中包含的UCI。
在本实施例中，基站在接收到终端发送的PUSCH之后，将获取映射影响因素，并根据获取到的映射影响因素，获取PUSCH中包含的UCI。
在一种可能的实现方式中，映射影响因素为基站配置给终端或终端上报给基站的。其中，配置给UCI的资源的子载波间隔、PUSCH的子载波间隔、配置给UCI的资源的时域位置、PUSCH的时域位置、配置给UCI的资源的频域位置、PUSCH的频域位置、UCI的传输时延、PUSCH的CBG信息、PUSCH的跳频情况、PUSCH的调制阶 数、PUSCH的码率、PUSCH中数据的重传信息、PUSCH中数据包的大小、配置给UCI的资源和PUSCH是否在同一个载波或同一个带宽部分、PUSCH的参考信号的位置或UCI的定时是由基站配置给终端的，终端的处理时延是由终端上报给基站的。
本申请实施例提供的上行控制信息的映射方法，通过确定映射影响因素，并根据该映射影响因素，将上行控制信息映射到中，然后将PUSCH发送给基站，其中，映射影响因素用于指示PUSCH或上行控制信息。由于终端设备在确定出映射影响因素之后，将根据不同的映射影响因素，按照不同的方式将上行控制信息映射到PUSCH中，由此，终端可以将上行控制信息UCI合理的映射到PUSCH中，并能够合理的通过PUSCH发送UCI。
