具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用 于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network，RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、 无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
首先，基站在传输物理下行共享信道(Physical Downlink Shared Channel，PDSCH)/或者物理下行控制信道(Physical Downlink Control Channel，PDCCH)(如指示半静态PDSCH释放的PDCCH等)后，终端在接收并解码完成后，要向基站侧反馈PDSCH/PDCCH的解码结果，告诉基站是否成功解码出PDSCH/半静态PDSCH，释放PDCCH。基站根据其反馈，进行下一步的调度决策，这一过程称为混合自动重传请求(Hybrid Automatic Repeat request，HARQ)。
在HARQ-应答ACK/否定应答NACK反馈模式中，终端成功解码PDSCH/PDCCH，则反馈ACK，否则反馈NACK。在HARQ仅否定应答NACK only反馈模式中，终端之后在没有成功解码PDSCH/PDCCH时反馈NACK，其余时候不反馈信息。

时间单元可以是时隙、子时隙、子帧、帧、OFDM符号集等。
由于在网络侧设备调度具有相同优先级的单播HARQ-ACK和多播 HARQ-ACK在相同时间单元反馈时，终端被配置单播HARQ-ACK的第一信道资源是可选地，如果终端未被配置单播HARQ-ACK的第一信道资源，则无法通过单播HARQ-ACK的第一信道资源将单播HARQ-ACK和/或多播HARQ-ACK反馈给网络侧设备。在本步骤中，在终端未被配置单播HARQ-ACK的第一信道资源的情况下，终端可以通过多播HARQ-ACK的目标信道资源，向网络侧设备反馈单播HARQ-ACK和多播HARQ-ACK，或反馈多播HARQ-ACK；或，终端可以通过单播HARQ-ACK的第二信道资源，向网络侧设备反馈单播HARQ-ACK和多播HARQ-ACK，或反馈单播HARQ-ACK。

具体地，预设比特数可以为2比特，例如单播HARQ-ACK的第二信道资源最多可以传输2比特，那么在单播HARQ-ACK和多播HARQ-ACK的总比特数等于2比特时，终端可以采取将单播HARQ-ACK和多播HARQ-ACK复用到单播HARQ-ACK的第二信道资源上反馈给网络侧设备的反馈方式。
在本实施例中，在网络侧设备调度具有相同优先级的单播HARQ-ACK和多播HARQ-ACK在相同时间单元反馈时，且在终端未被配置单播HARQ-ACK的第一信道资源的情况下，如果单播HARQ-ACK和多播HARQ-ACK的总比特数小于或等于预设比特数，则终端可以采取将单播 HARQ-ACK和多播HARQ-ACK复用到单播HARQ-ACK的第二信道资源上反馈给网络侧设备的反馈方式，实现了HARQ-ACK的反馈，提高了通信的可靠性。

在上述情况2中，预设比特数可以为2比特，由于单播HARQ-ACK和多播HARQ-ACK的总比特数大于2比特，假设单播HARQ-ACK的第二信道资源最多可以传输2比特，在这种情况下，可以选择丢弃多播HARQ-ACK，并通过单播HARQ-ACK的第二信道资源，向网络侧设备反馈单播HARQ-ACK的反馈方式。
在上述情况3中，单播HARQ-ACK的比特数大于或等于多播HARQ-ACK比特数，可以选择丢弃比特数较少的多播HARQ-ACK，并通过单播HARQ-ACK的第二信道资源，向网络侧设备反馈单播HARQ-ACK的反馈方式。

具体地，预设码率为单播HARQ-ACK的第一信道资源对应的最大码率或1。如果单播HARQ-ACK和多播HARQ-ACK的传输码率大于预设码率，无法通过单播HARQ-ACK的第一信道资源传输，终端可以选择部分丢弃多播HARQ-ACK，直至单播HARQ-ACK和剩余的多播HARQ-ACK的传输码率小于或等于预设码率，并将单播HARQ-ACK和剩余的多播HARQ-ACK复用到单播HARQ-ACK的第一信道资源上或多播HARQ-ACK的目标信道资源上反馈给网络侧设备的反馈方式。

在本实施例中，由于网络侧设备保证配置的单播HARQ-ACK的第一信道资源足够传输单播HARQ-ACK和多播HARQ-ACK的反馈，那么在网络侧设备调度具有相同优先级的单播HARQ-ACK和多播HARQ-ACK在相同时间单元反馈时，且在终端被配置单播HARQ-ACK的第一信道资源的情况下，终端可以选择将单播HARQ-ACK和多播HARQ-ACK复用到单播HARQ-ACK的第一信道资源上反馈给网络侧设备的反馈方式，实现了HARQ-ACK的反馈，提高了通信的可靠性。

具体地，预设码率为单播HARQ-ACK的第一信道资源对应的最大码率或1。如果单播HARQ-ACK和多播HARQ-ACK的传输码率小于或等于预设码率，由于终端被配置单播HARQ-ACK的第一信道资源，单播HARQ-ACK的第二信道资源不可用，终端可以将单播HARQ-ACK和多播HARQ-ACK复用到单播HARQ-ACK的第一信道资源上反馈给网络侧设备。
