  • NACK-only feedback mode the feedback resource is shared by all UEs in the multicast group.
  • the UE has no uplink feedback; even if the UE has NACK feedback, due to the shared feedback resources, the base station cannot identify the UE that feedbacks NACK, so the base station cannot use the PUCCH or PUSCH channel to perform uplink timing measurement, nor can it Send an uplink timing adjustment command to the UE, causing the UE to lose uplink synchronization.
  • This application discloses a solution for maintaining uplink synchronization (synchronization) when using multicast transmission and HARQ-ACK feedback for MBS services.

  • the base station and the UE support both unicast HARQ retransmission and multicast HARQ retransmission as an example. It is assumed that the base station performs multicast HARQ retransmission first, and then performs unicast HARQ retransmission. Since the retransmission is for the same HARQ process (process), if the stop-and-wait mechanism of the HARQ process is followed, that is, the base station sends the unicast HARQ retransmission after sending the multicast HARQ retransmission and receiving the HARQ-ACK feedback.
  • the retransmission delay is large; if it is supported to send unicast HARQ retransmission before receiving the HARQ-ACK of multicast HARQ retransmission, how to perform HARQ-ACK feedback for two HARQ retransmissions needs to be studied. For example, multicast HARQ retransmission decoding fails, unicast HARQ retransmission decoding succeeds, only NACK feedback is configured for multicast transmission, and ACK/NACK feedback is configured for unicast transmission.

Description

一种被用于无线通信中的方法和装置 技术领域
本申请涉及一种被用于无线通信系统中的方法和装置，尤其涉及无线通信中针对多播传输维持上行同步的方法和装置。
背景技术
虽然多播/广播(multicast/broadcast)传输特性在5G(Fifth Generation)最早的版本，即版本15和版本16中不支持，但是在很多重要的应用场景，比如公共安全(public safety)和紧急任务(mission critical)，V2X(Vehicle-to-Everything，车联网)应用，软件交付(software delivery)和小组通信(group communications)等，多播/广播通信的一对多传输特性可以显著提升系统性能和用户体验。
为了支持多播/广播通信，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#78次全会和RAN#80次全会之间讨论了5G广播演进，总结了两条技术特征，一是地面广播，二是混合模式多播。地面广播仅包括广播传输的传输模式，仅针对下行链路，通过大功率高架设发射塔实现大范围覆盖。5G广播业务的架构演进研究项目(SI，Study Item)在SA(Service and System Aspects)#85次会议上获得通过，其中目标A为在5GS(5G system，5G系统)中使能MBS(multicast/broadcast service，多播/广播业务)并使能识别的用例(use cases)。
发明内容
发明人通过研究发现，UE(User Equipment，用户设备)可以通过多播传输接收MBS业务。针对多播传输的可靠性需求，UE可以被配置HARQ-ACK(Hybrid Automatic Repeat Request-ACKnowledgement，混合自动重传请求-确定)反馈以提高传输可靠性；同时针对多播组包括较多组员的特点，UE可以被配置仅NACK(NACK-only，Negative ACKnowledgment，否定)的反馈模式以节省反馈资源。仅NACK的反馈模式中，反馈资源被多播组中的所有UE共享，当译码失败，UE反馈NACK，当译码成功，UE不反馈。如果UE在一段时间内一直译码成功，UE没有上行反馈；即使UE有NACK反馈，由于共享反馈资源，基站无法识别反馈NACK的UE，因此基站无法利用PUCCH或PUSCH信道进行上行定时测量，也无法向UE发送上行定时调整命令，引起UE上行失步。本申请公开了一种针对MBS业务采用多播传输和HARQ-ACK反馈时的维持上行同步(synchronization)的解决方案。
发明人通过研究发现，UE(User Equipment，用户设备)在RRC(Radio Resource Control，无线资源控制)连接(Connected)状态可以通过多播传输的传输模式或单播传输的传输模式接收MBS业务。基站可以为不同UE配置不同的传输模式和/或HARQ重传模式，比如可以为小区中心UE配置多播传输/多播HARQ重传以提高频谱效率；可以为小区边缘UE配置多播传输/单播HARQ重传以更好的适配UE信道；也可以为小区边缘UE配置多播传输/单播HARQ重传和多播HARQ重传以更好的利用多次重传进行合并译码提高译码成功率。以基站和UE同时支持单播HARQ重传和多播HARQ重传为例进行说明，假设基站先进行多播HARQ重传，然后进行单播HARQ重传。由于重传针对同一个HARQ进程(process)，如果遵从HARQ进程的停等(stop-and-wait)机制，即基站在发送多播HARQ重传并接收到HARQ-ACK反馈后再发送单播HARQ重传，则重传延时大；如果支持在接收到多播HARQ重传的HARQ-ACK之前发送单播HARQ重传，则如何针对两次HARQ重传进行HARQ-ACK反馈需要研究。比如多播HARQ重传译码失败，单播HARQ重传译码成功，针对多播传输配置仅NACK反馈，针对单播传输配置ACK/NACK反馈。如果UE同时在多播HARQ重传对应的反馈资源上反馈NACK，又在单播HARQ重传对应的反馈资源上反馈ACK；基站由于无法识别NACK来自于这个已经成功译码的UE还是其它UE，可能导致基站进行又一次重传，浪费资源；同时UE进行两次HARQ-ACK反馈浪费UE电量。本申请公开了一种针对MBS业务支持多播传输，多播HARQ重传和单播HARQ重传时确定HARQ-ACK反馈的解决方案。
虽然本申请的初衷是针对Uu空口，但本申请也能被用于PC5口。此外，不同场景(包括但不限于下行通信场景，NR(New Radio，新空口)V2X场景等)采用统一解决方案还有助于降低硬件复杂度和成本。 在不冲突的情况下，本申请的第一节点中的实施例和实施例中的特征可以应用到任一其它节点中，反之亦然。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。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS36系列、TS38系列、TS37系列中的定义。
