在NR Release 17版本的URLLC继续增强的WI(Work Item,工作项目)中,对UE(User Equipment,用户设备)内(Intra-UE)不同业务的复用(Multiplexing)是需要研究一个重点。
发明内容
当不同优先级的HARQ-ACK(Hybrid Automatic Repeat reQuest ACKnowledgement,混合自动重传请求确认)比特被复用到同一个PUCCH(Physical Uplink Control CHannel,物理上行链路控制信道)或PUSCH(Physical Uplink Shared CHannel,物理上行链路共享信道)中时,高优先级HARQ-ACK比特(如,针对URLLC业务的HARQ-ACK比特)的传输可靠性会受到低优先级HARQ-ACK比特(如,针对eMBB(enhanced Mobile BroadBand,增强移动宽带)业务的HARQ-ACK比特)的影响;如何保证高优先级HARQ-ACK比特的传输可靠性是实现不同业务之间的复用所需要解决的一个关键问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,在本申请的的描述中,采用URLLC作为一个典型应用场景或者例子;本申请也同样适用于其他场景,比如多发送接收节点传输,IoT(Internet of Things,物联网),MBS(Multicast and Broadcast Services,多播和广播服务),车联网,NTN(non-terrestrial networks,非地面网络)等,并取得类似的技术效果。此外,不同场景(包括但不限于URLLC,多发送接收节点传输,IoT,MBS,车联网,NTN)采用统一解决方案还有助于降低硬件复杂度和成本,或者提高性能。在不冲突的情况下,本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。在不冲突的情况下,本申请的实施例和实施例中的特征可以任意相互组合。
