Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及无线通信中的反馈信息的传输方案和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务识别和定义了4大用例组(Use Case Group)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。在3GPP RAN#80次全会上通过了NR V2X的技术研究工作项目(SI，Study Item)。在3GPP RAN#83次全会上决定对NR V2X启动WI(Work Item)进行标准化。
发明内容
NR V2X和现有的LTE V2X系统相比，一个显著的特征在于可以支持组播和单播以及支持HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)功能。在3GPP RAN1#95次会上同意引入一个独立的伴随链路(Sidelink)的反馈信道(PSFCH，Physical Sidelink Feedback Channel)。PSFCH被用于携带HARQ(混合自动重传请求进程，Hybrid Automatic Repeat Request)。另外，3GPP同意了用户设备(UE，User Equipment)可以将伴随链路(Sidelink)的HARQ反馈报告给基站。用户设备向基站报告伴随链路(Sidelink)的HARQ反馈设计需要解决方案。
针对NR V2X中的伴随链路的HARQ反馈报告的设计的问题，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，只是采用NR V2X场景作为一个典型应用场景或者例子；本申请也同样适用于面临相似问题的NR V2X之外的其它场景(比如中继网络，D2D网络，蜂窝网络，支持半双工用户设备的场景)，也可以取得类似NR V2X场景中的技术效果。此外，不同场景(包括但不限于NR V2X场景和伴随链路传输的场景)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，本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中，反之亦然。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。
本申请公开了一种被用于无线通信的第一节点中的方法，其特征在于，包括：
接收第一信息，所述第一信息被用于确定目标时频资源集合，所述目标时频资源集合在时域所包括的最早的多载波符号是第一多载波符号，所述目标时频资源集合所包括的频域资源属于第一频域资源池；
发送第一信号，所述第一信号所占用的频域资源属于第二频域资源池，所述第一频域资源池和所述第二频域资源池之间的频域关系被用于确定参考延时；
接收第二信号，第二多载波符号的起始时刻和所述第二信号的接收结束时刻之间的时间 间隔长度等于所述参考延时，所述第二多载波符号的起始时刻不早于所述第二信号的接收结束时刻；
当所述第一多载波符号不早于所述第二多载波符号时，发送第二信息；
其中，当所述第二信息被发送时，所述目标时频资源集合被用于所述第二信息的传输；所述第一信号所占用的时频资源被用于确定所述第二信号所占用的空口资源；所述第二信号所携带的信息被用于确定所述第二信息，所述第一信息的发送者和所述第二信号的发送者不相同。
作为一个实施例，通过所述第一多载波符号和所述第二多载波符号的早晚关系来确定所述第二信息的发送，使得伴随链路的HARQ-ACK向基站发送报告的定时满足用户设备的最低的时延要求，考虑了用户设备的处理能力，从而减轻用户设备在实现时的负担和复杂性。

    其中，当所述第二信息被发送时，所述目标时频资源集合被用于所述第二信息的传输；所述第一信号所占用的时频资源被用于确定所述第二信号所占用的空口资源；所述第二信号所携带的信息被用于确定所述第二信息，所述第一信息的发送者和所述第二信号的发送者不相同。
  11. 一种被用于无线通信的第二节点中的方法，其特征在于，包括：
    发送第一信息和第一信令，所述第一信息被用于指示目标时频资源集合，所述目标时频资源集合在时域所包括的最早的多载波符号是第一多载波符号，所述目标时频资源集合所包括的频域资源属于第一频域资源池；
    接收第二信息；
    其中，所述第一信令被用于指示第一信号所占用的时频资源，所述第一信号所占用的频域资源属于第二频域资源池，所述第一频域资源池和所述第二频域资源池之间的频域关系被用于确定参考延时；所述第一信号所占用的时频资源被用于指示第二信号所占用的空口资源；第二多载波符号的起始时刻和所述第二信号的接收结束时刻之间的时间间隔长度等于所述参考延时，所述第二多载波符号的起始时刻不早于所述第二信号的接收结束时刻；所述目标时频资源集合被用于所述第二信息的传输；所述第二信号所携带的信息被用于确定所述第二信息，所述第二信号的发送者是所述第二节点设备之外的节点设备；所述第一多载波符号不早于所述第二多载波符号。
