Description

信息传输方法、终端设备及接入网设备
本申请要求于2017年1月6日提交中国专利局、申请号为201710011443.4、申请名称为“信息传输方法、终端设备及接入网设备”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，尤其涉及一种信息传输方法、终端设备及接入网设备。
背景技术
第五代移动通信(the 5th Generation Mobile Communication，简称5G)新无线接入技术(New Radio Access Technology，简称NR)致力于支持更高系统性能，支持不同的业务，不同的部署场景和不同的频谱。其中，上述所说的业务例如可以为增强的移动宽带(enhanced Mobile Broadband，简称eMBB)业务、机器类型通信(Machine Type Communication，简称MTC)业务、超可靠低延迟通信(Ultra-reliable and low latency communications，简称URLLC)业务、多媒体广播多播业务(Multimedia Broadcast Multicast Service，简称MBMS)和定位业务等。上述所说的部署场景例如可以为室内热点(Indoor hotspot)场景、密集城区(dense urban)场景、郊区场景、城区宏覆盖(Urban Macro)场景、高铁场景等。上述所说的频谱例如可以为100GHz以内的任一的频率范围。
为满足5G NR中各业务、各部署场景以及各频谱等对应的业务需求，该5G NR中需增加上行控制信息(Uplink Control Information，简称UCI)的类型。这使得终端设备在同一个时间单元内可能需通向接入网设备上报多个UCI。
然而，当终端设备具有多个UCI需要同时上报至接入网设备，易产生UCI的上报冲突，会导致该多个UCI全部无法上报，影响数据传输性能，难以保证业务需求。
发明内容
本申请实施例提供一种信息传输方法、终端设备及接入网设备，以避免UCI的上报冲突，提高数据传输性能，保证业务需求。

具体实施方式
本申请下述各实施例提供的信息传输方法、终端设备及接入网设备，可适用于5G NR通信技术或者其他任一通信技术的演进通信技术中。
图1为本申请实施例适用的通信系统的架构图。本申请下述各实施例提供的方法可应用于图1所示的通信系统中。如图1所示，通信系统中包括至少一个接入网设备101。每个接入网设备101通过无线接口服务至少一个终端设备102。
需要说明的是，对于图1所示的通信系统中包括的接入网设备101的数量、每个接入网设备101服务的终端设备102的数量，均根据实际网络需求部署。本申请对此不进行具体限定。
在图1中，仅示例性的示意了一个接入网设备101以及接入网设备101服务的终端设备102。图1中示意的内容并不是对通信系统中包括的接入网设备101的数量、 接入网设备101服务的终端设备102的数量的具体限定。
图1中所示的终端设备102，可以是指向用户提供数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的无线设备。无线终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，简称SIP)话机、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字助理(Personal Digital Assistant，简称PDA)等设备。无线终端也可以称为订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)、智能手机(smartphone)、自动驾驶设备(Automotive Device)或物联网设备(Internet Of Things Device)。
图1中所示的接入网设备101可以为无线电台站的一种形式，是指在一定的无线电覆盖区中，通过移动通信交换中心与移动电话终端之间进行信息传递的无线电收发信电台；或者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。该接入网设备可以用于将收到的空中帧与互联网协议(Internet Protocol，简称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。该接入网设备还可协调对空中接口的属性管理。例如，该接入网设备可以为基站，如基本传输站(Base Transceiver Station，简称BTS)、基本站点(Node Base，简称NodeB)、演进型基站(evolutional Node B，简称eNB)等任一，本申请并不限定。
如下结合多个实例进行举例说明。
图2为本申请实施例提供的一种信息传输方法的流程图。如图2所示，该方法可包括：
S201a、接入网设备向终端设备发送指示信息。
步骤S201a是可选的步骤。接入网设备可以是通过物理下行信道向终端发送该指示信息，该信息可以是以单播的方式单独发给终端，也可以是以广播的方式发给终端。该物理下行信道例如可以包括如下至少一种：物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)、物理控制格式指示信道(Physical Control Format Indicator Channel，简称PCFICH)、物理混合自动重发请求指示信道(Physical Hybrid Automatic Repeat Request Indicator Channel，简称PHICH)、物理广播信道(Physical Broadcast Channel，简称PBCH)、物理多播信道(Physical Multicast Channel，简称PMCH)等。
相应的，该终端设备可从该接入网设备接收该指示信息。
S201、终端设备确定在同一时间单元内需要发送的N个UCI，N为大于或等于2的整数，该N种UCI包括如下中的至少一种：波束赋形信息、缓存状态报告(Buffer  Status Report，简称BSR)信息和调度请求(Scheduling Request，简称SR)信息。
其中，该波束赋形信息可以为波束赋形指示(Beam Forming Indication，简称BFI)，可以是在上行信道上发送的波束赋形指示信令，也可以是指示下行信道所在的波束的信息，也可以是指示天线端口(antenna port)的信息。该BFI可包括该终端设备所选择的波束标识(Beam IDentification)，用于向接入网设备上报终端设备选择了哪个波束、或者，该终端设备所选择的波束的信道质量指示等信息，用于向接入网设备上报终端设备选择的波束上的信道质量。BFI还可包括该终端设备所选择的天线端口，比如下行参考信号的天线端口。该BSR信息可包括：该终端设备待发送的上行数据量的指示信息等。该SR信息可包括：该终端设备是否需发送上行数据的指示信息和/或待发送的上行数据量的指示信息等。其中，该待发送的上行数据量的指示信息可以通过比特数表示。
可选的，多个UCI所占用的资源的时间单元的长度可能相同，也可能不同，例如子载波间隔不同导致的符号长度不同，以及占用的符号数也可能不同。例如，一个子帧包括两个时隙，每个时隙7个符号。一个子帧有14个符号，但对不同的UCI，频域上的子载波间隔(SubCarrier Spacing，简称SCS)不同，导致了符号长度不同，如下表1所示。多个UCI中不同UCI的时间单元可能发生部分重叠，也可能全部重叠。例如一个UCI可通过物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)发送的。承载这个UCI的字帧长度是1毫秒，这个子帧有14个符号，且这14个符号都用于发送该UCI。第二个UCI也通过PUCCH发送，承载这个UCI的字帧长度是0.5毫秒，该子帧也有14个符号，且这14个符号都用来发送该UCI。这两个UCI都用14个符号发送。但对于长度1毫秒的子帧而言，一个符号的时域长度是长度0.5毫秒的子帧的两倍。假设第一个UCI的PUCCH的时域起始位置和第二个UCI的PUCCH的起始位置一样，第二个UCI的PUCCH和第一个UCI的PUCCH的前0.5毫秒重叠。这两个UCI部分重叠。如果发送这两个UCI的PUCCH时域起始相同，都占14个符号，而且这两个PUCCH的符号时域长度相同，则这两个UCI在时域上全部重叠。
一个UCI所占用的资源的时间单元可以是至少一个无线帧、至少一个子帧、至少一个时隙或者至少一个符号等。
而且，发送一个UCI的PUCCH可以不是14个符号。比如，发送UCI的PUCCH是在时域上占1个符号或者2个符号。这样也会导致两个UCI在时域上会发生部分重叠，而并非完全重叠。
该终端设备还可以是根据预设的多个UCI的时间单元信息，将该待发送的多个UCI中时间单元部分重叠或全部重叠的N个UCI确定为同一时间单元内需要发送的N个UCI。也就是说，该终端设备根据定时关系确定的发送时刻，比如基站在D子帧发送下行信息，UE根据定时关系确定发送时刻为D+k。预设在该终端设备侧的该预设的多种UCI的时间单元信息，确定该同一时间单元内需要发送的N种UCI。该多个UCI的时间单元信息可包括：预设的该多个UCI中各UCI的定时发送信息、触发信息等。
也就是说，如上所示的S201中终端设备还可以根据该指示信息，确定承载多个UCI的时间单元信息，根据承载该多个UCI的时间单元信息，将该多个UCI中时间单元部分重叠或全部重叠的N个UCI确定为同一时间单元内需要发送的该N个UCI。其 中，该同一时间单元可以包括至少一个无线帧、至少一个子帧、至少一个时隙或者至少一个符号等。该终端设备可以是根据该M个UCI中各UCI的时频资源，分别向接入网设备发送该M个UCI。
其中，该指示信息可包括：接入网设备为该终端设备配置的各UCI的发送周期和/或时间偏移等信息。例如，该终端设备分别接收接入网设备配置的秩指示(Rank Indicator，简称RI)、预编码矩阵指示(Precoding Matrix Indicator，简称PMI)/信道质量指示(Channel Quality Indicator，简称CQI)的发送周期和时间偏移。该终端设备可根据配置的发送周期和时间偏移确定承载RI、PMI/CQI的时间单元。该终端设备在承载RI的时间单元上发送RI；该终端设备在承载PMI/CQI的时间单元上发送PMI/CQI。
S202、终端设备根据该N个UCI的优先级，向接入网设备发送M个UCI；该M个UCI的优先级高于该N个UCI中另外N-M个UCI的优先级，M为小于或等于N的正整数。
该终端设备可以是根据预设的优先级规则，确定该N个UCI的优先级，并从该N个UCI中确定优先级最高的M个UCI，继而向接入网设备发送该M个UCI，而将该N个UCI中优先级最低的N-M个UCI进行丢弃，而并不发送至接入网设备。该M个UCI的优先级高于该N个UCI中另外N-M个UCI的优先级。
可选的，该终端设备可以是在承载该M个UCI中各UCI的时间单元上分别向接入网设备发送该M个UCI中的各UCI。
可选的，如上所示的终端设备可根据该N个UCI的优先级，在该时间单元向接入网设备发送M个UCI。该时间单元可以为承载该M个UCI的时间单元在时域上所重叠的部分。
相应的，该接入网设备从终端设备接收M个UCI。
可选的，M小于N。终端设备确定在同一时间单元内需要发送的N个UCI，并根据该N个UCI的优先级，向接入网设备发送该N个UCI中优先级最高的M个UCI。该方法中，该终端设备向接入网设备发送优先级最高的M个UCI，对该N个UCI进行排序和取舍，而并非将该N个UCI均上报至该接入网设备，有效避免了UCI的上报冲突，保证UCI的上报成功率，有效保证数据传输性能及业务需求。
可选的，该N个UCI中还可包括信道状态信息(Channel State Information，简称CSI)。该波束赋形信息、该BSR信息和该SR信息中至少一个UCI的优先级可高于该CSI的优先级。
可选的，若该N个UCI中仅包括该波束赋形信息和CSI，其中，该波束赋形信息的优先级可高于CSI的优先级。该终端设备可以是根据该N个UCI的优先级，仅向接入网设备发送该波束赋形信息，而将该CSI丢弃，不发送该CSI。
本申请实施例的方法中，该波束赋形信息的优先级高于CSI的优先级，可使得接入网设备及时接收该波束赋形信息，从而有效避免接入网设备再次收到该波束赋形信息的较长等待时间，有效保证业务需求。
可选的，该CSI包括如下中的至少一个：RI、PMI、CQI、预编码类型指示(Precoding Type Indicator，简称PTI)。CQI用于指示信道质量，PMI用于指示预编码矩阵，PTI 用于指示预编码类型，RI用于指示信道矩阵的秩。
其中，PMI可包括：宽带(Wideband，简称WB)PMI和/或子带(SubBand，简称SB)PMI。CQI可包括：WB CQI和/或SB CQI。
可选的，该波束赋形信息的时域发送周期为T个预设时间长度，该CSI的时域发送周期为P个该预设时间长度，其中T≥P，T、P均为正整数。
可选的，T可以为P的A倍，其中，A为正整数。
也就是说，该波束赋形信息的时域发送周期可大于或等于该CSI的时域发送周期，由于相对于CSI，波束赋形信息变化较慢，不需要频繁更新，因而发送周期可以相对较长，以节省信令开销。
可选的，该N个UCI还可包括确认(ACKnowledge，简称ACK)/否定确认(Negative ACKnowledge，简称NACK)，该波束赋形信息、该BSR信息和该SR信息中至少一个UCI的优先级低于该ACK/NACK的优先级。
若UCI包括：BFI、BSR、SR、RI、WB CQI/PMI、SB CQI/PMI、ACK/NACK这几种类型的UCI，则该终端设备还可以采用如下多种方式确定N个UCI的优先级。其中，BFI表示该波束赋形信息，BSR表示该BSR信息，SR表示该SR信息。其中，CQI用于指示信道质量，PMI用于指示预编码矩阵，PTI用于指示预编码类型，RI用于指示信道矩阵的秩。ACK/NACK用于反馈是否正确接收数据，BSR用于上报缓存状态，SR用于发送调度请求，BFI用于向基站上报终端设备选择了哪个波束。
可选的，该N个UCI的优先级从高至低可依次表示为：BFI>ACK/NACK>SR>RI>WB CQI/PMI>SB CQI/PMI>BSR。针对不同的波束，会有不同的UCI，而UCI对应的参数都是与波束相关的，因此，为保证接入网设备及时准确的解析到终端设备所选择的波束等信息，在本申请实施例的方法中，该BFI的优先级可以高于N个UCI中的其他UCI的优先级。并且，ACK/NACK决定接入网设备与终端设备间的数据重传等信息，SR即便未传输成功还可以继续传输，而与CSI相比，SR的传输更紧急，因此，该SR的优先级可低于ACK/NACK的优先级，但高于该CSI的优先级。在该CSI所包括的各UCI中，RI的优先级可高于WB CQI/PMI的优先级，该WB CQI/PMI的优先级可高于SB CQI/PMI的优先级。若该BSR是通过物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)传输，而该PUCCH的优先级可大于该PUSCH的优先级，因此，该BSR的优先级可低于SB CQI/PMI的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：ACK/NACK>BFI>SR>RI>WB CQI/PMI>SB CQI/PMI>BSR。由于ACK/NACK是针对接入网设备向终端设备下发的下行数据，因此，对于该接入网设备来说，发送该下行数据的波束等资源信息是已知的，则该N个UCI中，BFI的优先级可低于ACK/NACK的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：ACK/NACK>SR>BFI>RI>WB CQI/PMI>SB CQI/PMI>BSR。由于终端设备发送SR的资源实际是由接入网设备所配置的，即无论对于终端设备通过哪个波束发送SR，接入网设备只要获知该终端设备具有发送上行数据的需求便可，因此，在本申请实施例的方法中，该N个UCI中，BFI的优先级可低于SR的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：ACK/NACK>SR>RI>BFI>WB CQI/PMI>SB CQI/PMI>BSR。由于该RI一旦解析错误，将会导致至少一个码字的混淆，并且，该RI的上报周期，也就是时域发送周期大于预设的周期限值，一旦解析失败被丢弃，等待下次上报的时间较长，因此，在本申请实施例的方法中，该N个UCI中，BFI的优先级还可低于RI的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：BFI>SR>ACK/NACK>RI>WB CQI/PMI>SB CQI/PMI>BSR。由于SR为终端设备具有上行数据的发送需求的情况下，向接入网设备发送的调度资源请求，然而，ACK/NACK为该终端设备针对接入网设备发送的下行数据的接收反馈，该上行数据的发送需求更紧迫，因此，在本申请实施例的方法中，该N个UCI中，SR的优先级还可高于ACK/NACK的优先级，而ACK/NACK的优先级高于CSI的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：BFI>ACK/NACK>SR>RI>BSR>WB CQI/PMI>SB CQI/PMI。由于BSR包括该终端设备待发送的上行数据量，其也具有SR的功能，如BSR的时域发送周期大于CQI的时域发送周期，则BSR等待下次发送机会的时间更长，因此，在本申请实施例的方法中，该N个UCI中，BSR的优先级可高于WB CQI/PMI的优先级。
可选的，该N个UCI的优先级从高至低可依次表示为：BFI>ACK/NACK>BSR>RI>WB CQI/PMI>SB CQI/PMI。如该终端设备在同一时间单元内发送的N个UCI中不存在SR，而存在BSR，则在本申请实施例的方法中，该N个UCI中，BSR的优先级可高于RI的优先级。
可选的，本申请实施例提供的信息传输方法中，在如上所示的S202中终端设备根据该N种UCI的优先级，在该时间单元内向接入网设备发送M种UCI之前，终端设备还可以是采用如下所示的承载UCI的资源对应的子载波间隔(SubCarrier Spacing，简称SCS)、承载UCI的资源对应的时间长度、UCI对应的信息类型或者业务类型中至少一种确定该N种UCI的优先级。
可选的，如上所示的S202中终端设备根据该N个UCI的优先级，向接入网设备发送M个UCI之前，该方法还可包括：
该终端设备根据SCS确定UCI的优先级，SCS越大，对应的UCI的优先级越高；也就是说，SCS越小，对应的UCI的优先级越低。
例如，N＝3，一共有3个UCI。承载第一个UCI的资源是PUCCH，该PUCCH的SCS是15KHz；承载第二个UCI的资源是PUCCH，该PUCCH的SCS是30KHz；承载第三个UCI的资源是PUCCH，该PUCCH的SCS是60KHz。则第三个UCI的优先级大于第二个UCI的优先级；第二个UCI的优先级大于第一个UCI的优先级。即在这三个UCI中，第三个UCI的优先级最高，第二个UCI的优先级次高，第一UCI的优先级最低。
或者，
该终端设备根据时间长度确定UCI的优先级，时间长度越短，对应的UCI的优先级越高；时间长度越长，对应的UCI的优先级越低。
例如，N＝3，一共有3个UCI。承载这三个UCI的资源是PUCCH。承载第一 UCI的PUCCH有1个符号；承载第二个UCI的PUCCH有3个符号；承载第三个UCI的PUCCH有2个符号。且这三个UCI中每个符号的长度都一样。则第一个UCI的优先级最高，第二个UCI的优先级最低，第三个UCI的优先级次高。也就是说，第一个UCI的优先级大于第三个UCI的优先级；第三个UCI的优先级大于第二个UCI的优先级。
或者，
该终端设备根据信息类型或业务类型确定UCI的优先级，信息类型或业务类型的优先级越高，对应的UCI的优先级越高；也就是说，信息类型或业务类型的优先级越低，对应的该UCI的优先级越高越低。
本申请实施例中的UCI对应的业务类型，为上行信道发送的上行信息的业务类型，如eMBB业务、MTC业务、URLLC业务。本申请实施例中的UCI对应的UCI信息类型，包括：BFI、BSR、SR、RI、WB CQI/PMI、SB CQI/PMI、ACK/NACK这几种类型的UCI。
其中，该BFI、该BSR信息和该SR信息中至少一个UCI的优先级可高于该RI、WB CQI/PMI、SB CQI/PMI的优先级，小于该ACK/NACK的优先级。该UCI对应的信息类型对应的优先级，可以是采用上述类似的方式确定的，在此不再赘述。
其中，URLLC业务的UCI的优先级可高于eMBB业务的UCI的优先级，该eMBB业务的UCI的优先级可高于mMTC业务的UCI的优先级。举例来说，若该N个UCI包括第一UCI、第二UCI和第三UCI，其中，第一UCI为URLLC业务的UCI的优先级，第二UCI为eMBB业务的UCI，第三UCI为mMTC业务的UCI，则该N个UCI中，该第一UCI的优先级可高于第二UCI的优先级，第二UCI的优先级可高于第三UCI的优先级。
也就是说，本申请实施例的方法中，终端设备可以是根据该N个UCI中，承载每个UCI的资源对应的SCS确定，该每个UCI的优先级；也可以是根据承载该每个UCI的资源对应的时间长度确定，该每个UCI的优先级；还可以是根据该每个UCI对应的信息类型或者业务类型的优先级确定该每个UCI的优先级。本实施例的子载波间隔，为承载上行信道的资源的子载波间隔。可以是物理的频域子载波间隔，如3.75kHz、7.5kHz、15kHz、30kHz、60kHz、120kHz、240kHz、480kHz。
本实施例的时间长度，为承载上行信道的资源的时间长度。如符号长度、时隙长度、子帧长度等，又如长PUCCH时间长度可以为0.5ms或者1ms，而短PUCCH的时间长度可以为1个符号或者2个符号等，对于15kHz的SCS，1个符号的长度可以为71us。
其中，承载UCI的资源可以为承载UCI的时频资源，该时频资源可以为PUCCH上的时频资源。承载该N个UCI中，不同UCI的资源对应的SCS可不同，也可相同。不同的子载波间隔可对应不同的(时域)符号长度。即使N个UCI中承载多个UCI的资源对应的SCS相同，也就是说符号的长度相同，承载不同UCI的资源对应的时间长度也可能不同，因为它们的符号个数可能不同。
图3为本申请实施例提供的一种子帧的时频资源的结构示意图。本申请实施例所使用的通信系统，如5G NR中的时频资源在时域上包括：多个10ms的无线帧，一个无线帧包括10个1ms的子帧，一个子帧中有两个时隙(slot)。时频资源在频域上可 包括：多个子载波，频域调度的颗粒度可以为资源块组(Resource Block Group，简称RBG)，资源块组可包括：多个资源块(Resource Block，简称RB)对。1个RB对包括：时域上一个子帧，频域上12个子载波的二维资源块。图3中以一般循环前缀(Normal Cyclic Prefix，简称NCP)为例，对于该NCP，每个时隙可包括7个符号，一个RB对可包括168个时频资源单元(Resource Element，简称RE)。对于扩展循环前缀(Extended Cyclic Prefix，简称ECP)(图3未示出)，每个时隙可包括6个符号，一个RB对可包括144个RE。
承载该UCI的资源可以包括至少一个图3中所示的RB，也可以包括图3中所示的时域为至少一个符号，频域为至少一个子载波构成的至少一个RE。
图3中的一个子载波还可称为一个SCS。在该5G NR中，一个子帧内各包括多种不同的SCS，而不同的SCS可对应不同的符号长度。也就是说，该图3所示的时频资源中，每个符号长度的可能不同。
承载该UCI的资源对应的SCS可以为承载该UCI的资源在频域上的子载波间隔。承载该UCI的资源对应的时间长度可以为承载该UCI的资源在时域上的资源长度。表1给出了本申请实施例中SCS与符号长度的对应关系。

根据该表1可知，在本申请实施例的方法中，不同频域长度的SCS，其对应的符号长度可不同。即不同的子载波间隔可对应不同的符号长度。其中，SCS可以为15kHz*2n，n是整数，承载该UCI的资源对应的SCS可以为3.75，7.5……480kHz的8种SCS中任一。承载该UCI的资源对应的时间长度可以包括：至少一个符号，每个符号的长度可以为根据承载该UCI的资源对应的SCS，采用上述表1所确定的符号长度。表1中F0、F1及F2可分别对应8种SCS中任意三个不同的SCS。
若该N个UCI中，一个UCI为低时延要求的业务如URLLC业务的UCI，承载该一个UCI的资源对应的SCS越大，承载该一个UCI的资源对应的符号越短。若该N个UCI中，另一个UCI为eMBB业务或mMTC业务等对时延不敏感业务的UCI，则承载该另一个UCI的资源对应的SCS越小，承载该另一个UCI的资源对应的符号越长。因而本申请实施例提供的方法中，承载UCI的资源对应的SCS越大，该UCI的优先级越高，承载该UCI的资源对应的SCS越小，该UCI的优先级越低，或者，承载该UCI的资源对应的时间长度越短，该UCI的优先级越高，承载该UCI的资源对应的时间长度越长，该UCI的优先级越低，可使得低时延业务的UCI的优先级较高，而时延不敏感业务的UCI的优先级更低，有效地使得接入网设备尽可能的接收到的低时延业务的UCI，有效保证低时延业务的可靠性及时延需求等。
可选的，该终端设备根据SCS确定UCI的优先级还包括：
若SCS相同，该终端设备根据信息类型或业务类型确定UCI的优先级。
例如，终端设备首先根据SCS确定UCI的优先级，N＝6个UCI，其中2个UCI的SCS一样，都是最高优先级；则终端设备进一步根据UCI的信息类型或业务类型确定UCI的优先级，例如第一个UCI的信息类型为BFI，第二个UCI的信息类型为CQI，终端设备上报BFI。BFI的优先级高于CQI的优先级。
可选的，该终端设备根据时间长度确定UCI的优先级还包括：
若时间长度相同，该终端设备根据信息类型或业务类型确定UCI的优先级。
也就是说，若该N个UCI中，承载多个UCI的资源对应的SCS或时间长度相同，本申请实施例提供的方法中，该终端设备还可根据该多个UCI中，各UCI对应的信息类型或者业务类型确定该各UCI的优先级，以准确对N个UCI进行排序，继而向接入网设备发送该N个UCI中优先级最高的M个UCI。
可选的，该终端设备根据信息类型或业务类型确定UCI的优先级还包括：
若信息类型或业务类型相同，该终端设备根据SCS或时间长度确定UCI的优先级。
其中，该N个UCI中存在多个信息类型或业务类型相同的UCI时，本申请实施例提供的方法中，该终端设备还可根据该多个信息类型相同的UCI中中，承载各UCI的资源对应的SCS或时间长度确定该各UCI的优先级，以准确对N个UCI进行排序，继而向接入网设备发送该N个UCI中优先级最高的M个UCI。
例如，终端设备首先根据信息类型确定UCI的优先级，N＝6个UCI，其中2个UCI的信息类型一样，都是最高优先级的信息类型，如BFI；则终端设备进一步根据UCI的SCS或时间长度确定UCI的优先级，例如第一个UCI承载在长PUCCH上，第二个UCI承载在短PUCCH上，则第二个UCI的优先级高于第一UCI的优先级，终端设备上报第二个UCI。
对于接入网设备侧，UCI的优先级为该接入网设备根据SCS确定的，SCS越大，对应的UCI的优先级越高；或者，
UCI的优先级为该接入网设备根据时间长度确定的，时间长度越短，对应的UCI的优先级越高；或者，
UCI的优先级为该接入网设备根据信息类型或业务类型确定的，信息类型或业务类型的优先级越高，对应的UCI的优先级越高。
可选的，若UCI的优先级为该接入网设备根据SCS确定的，而SCS相同，UCI的优先级为该接入网设备设备根据信息类型或业务类型确定的。
可选的，若UCI的优先级为该接入网设备根据时间长度确定的，而时间长度相同，UCI的优先级为该接入网设备设备根据信息类型或业务类型确定的。
可选的，若UCI的优先级为该接入网设备根据信息类型或业务类型确定的，而信息类型或业务类型相同，UCI的优先级为该接入网设备根据SCS或时间长度确定的。
具体地，接入网设备根据SCS、时间长度、以及根据信息类型或业务类型，确定UCI的优先级的具体实现及有益效果可参见上述终端设备确定UCI的优先级的描述，在此不再赘述。
可选的，如上所示的S202中终端设备根据该N个UCI的优先级，向接入网设备 发送M个UCI，可包括：
该终端设备根据该N个UCI的优先级，通过PUCCH向该接入网设备发送该M个UCI。
图4为本申请实施例提供的另一种信息传输方法的流程图。如图4所示，该方法在如上所示的终端设备根据该N个UCI的优先级，通过PUCCH向该接入网设备发送该M个UCI，包括：
S401、若该N个UCI的总比特数大于该PUCCH能够承载的最大比特数，终端设备根据该N个UCI的优先级，通过该PUCCH向该接入网设备发送该M个UCI，其中，该M个UCI的总比特数小于或等于该PUCCH的最大比特数。
可选的，为保证接入网设备尽可能接收到终端设备发送的UCI，M可以为根据优先级，PUCCH能够承载的UCI的最大个数。
也就是说，在该M个UCI的基础上，如增加一个余下的N-M个UCI中优先级最高UCI，则该增加后的所有UCI的总比特数会大于该PUCCH的最大比特数。即M+1个UCI的总比特数大于该PUCCH的最大比特数。
可选的，如上所示的，该S401中若该N个UCI的总比特数大于该PUCCH能够承载的最大比特数，终端设备根据该N个UCI的优先级，通过该PUCCH向该接入网设备发送该M个UCI之前，该方法还可包括：
S401a、终端设备比较该N个UCI的总比特数与该PUCCH能够承载的最大比特数。
若该N个UCI的总比特数大于该PUCCH能够承载的最大比特数，则执行上述S401；若该N个UCI的总比特数小于或等于该PUCCH能够承载的最大比特数，该方法中终端设备可以向接入网设备发送该N个UCI。
本申请实施例的方法可在N个UCI的总比特数大于该PUCCH能够承载的最大比特数的情况下，向该接入网设备发送该N个UCI中优先级最高的M个UCI，可有效避免在PUCCH上上报该N个UCI所导致的上报冲突，提高了UCI的上报成功率，有效保证数据传输性能及业务需求。
可选的，该接入网设备从终端设备接收M个UCI之后，对应该N-M个UCI，该方法还可包括：
该接入网设备确定距离当前时间最近的该N-M个UCI对应的历史参数。
具体地，该距离当前时间最近的该N-M个UCI对应的历史参数可以为该终端设备最近一次上报的该N-M个UCI的参数。该接入网设备在确定该N-M个UCI个UCI对应的历史参数后，可使用该N-M个UCI对应的历史参数执行该N-M个UCI对应的操作。
该接入网设备从该终端设备接收该M个UCI后，还确定距离当前时间最近的该N-M个UCI对应的历史参数，继而使用该N-M个UCI对应的历史参数，在避免UCI上报冲突，提高了UCI的上报成功率的基础上，还可有效保证接入网设备在接收到UCI较少的情况下的业务需求，采用该距离当前时间最近的该N-M个UCI对应的历史参数，保证该终端设备的业务需求。
