Description

一种被用于无线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其是涉及支持在非授权频谱(Unlicensed Spectrum)上进行数据传输的通信方法和装置。
背景技术
在5G系统中，eMBB(Enhance Mobile Broadband，增强型移动宽带),和URLLC(Ultra Reliable and Low Latency Communication，超高可靠性与超低时延通信)是两大典型业务类型。在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)新空口Release 15中已针对URLLC业务定义了一个新的调制编码方式(MCS,Modulation and Coding Scheme)表。
为了支持更高要求的URLLC业务，比如更高可靠性、更低延迟(0.5-1ms)等，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#80次全会上通过了新空口Release 16的URLLC增强的SI(Study Item，研究项目)。其中，对调度/HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)/CSI(Channel State Information，信道状态信息)处理时序(timeline)的增强是需要研究一个重点。
发明内容
发明人通过研究发现，对于低延迟要求的应用需要更快的反馈HARQ/CSI，而对于延迟要求不高的应用则可以较慢的反馈HARQ/CSI，因此如何针对不同延迟要求来配置HARQ/CSI反馈是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。
本申请公开了一种用于无线通信的用户设备中的方法，其特征在于，包括：
接收第一信令；
在第一时间窗中接收第一无线信号；
在第二时间窗中发送针对所述第一无线信号的反馈；
其中，所述第一信令被用于确定所述第一无线信号所占用的时域资源；第一时域偏差是所述第二时间窗与所述第一时间窗在时域上的偏差；如果所述第一信令携带第一标识，所述第一时域偏差是K1个第一类备选偏差中之一，所述K1是正整数；如果所述第一信令携带第二标识，所述第一时域偏差是K2个第二类备选偏差中之一，所述K2是正整数；所述第一标识不同于所述第二标识，所述K2个第二类备选偏差中至少一个第二类备选偏差和所述K1个第一类备选偏差都不同。
作为一个实施例，本申请要解决的问题是：如何针对新空口Release16对更低延迟要求，对HARQ-ACK反馈延迟配置的方案进行增强。
作为一个实施例，本申请要解决的问题是：在新空口Release 15中，HARQ-ACK(Hybrid Automatic Repeat reQuest ACKnowledgement，混合自动重传请求确认)反馈延迟的配置可以通过DCI(下行控制信息，Downlink Control Information)(DCI format 1_0或1_1中的PDSCH(Physical Downlink Shared CHannel，物理下行共享信道)-to-HARQ_feedback timing indicator域)指示或者RRC(Radio Resource Control，无线电资源控制)配置(DCI format1_1中当PDSCH-to-HARQ_feedback timing indicator域为0比特时)。通过DCI指示的方法是从RRC配置的一个HARQ-ACK反馈延迟的范围中选择一个延迟值，而通过RRC配置的方法是RRC配置一个HARQ-ACK反馈延迟。要在新空口Release 16中支持更低延迟的HARQ反馈， 如何对上述DCI指示的方法或者RRC配置的方法进行增强是需要解决的一个关键问题。
作为一个实施例，上述方法的实质在于，第一信令是调度PDSCH的DCI信令，第一无线信号是被第一信令调度的PDSCH，针对所述第一无线信号的反馈是HARQ-ACK，第一时间窗是PDSCH所在的时隙，第二时间窗是HARQ-ACK所在的时隙，第一时域偏差是HARQ-ACK相对PDSCH的反馈延迟，第一标识和第二标识是用于DCI的CRC加扰的两个不同的RNTI；如果检测到DCI是由第一标识加扰时，HARQ-ACK相对PDSCH的反馈延迟属于K1个第一类备选偏差；如果检测到DCI是由第二标识加扰时，HARQ-ACK相对PDSCH的反馈延迟属于K2个第二类备选偏差。采用上述方法的好处在于，将用于加扰DCI的CRC的RNTI与HARQ-ACK反馈延迟的范围相关联，通过识别RNTI可以隐性确定HARQ-ACK反馈延迟的范围；一方面，对于通过DCI信令从HARQ-ACK反馈延迟的范围中选择一个延迟值的情况，避免了为了支持更低延迟在DCI中引入更多的比特开销；另一方面，对于通过RRC信令指示HARQ-ACK反馈延迟的情况，配置多个与RNTI有关的HARQ-ACK反馈延迟的范围，解决了不同业务对延迟的不同要求。

-.将用于加扰DCI的CRC的RNTI与HARQ-ACK反馈延迟的范围相关联，通过识别RNTI可以隐性确定HARQ-ACK反馈延迟的范围。
-.对于通过DCI信令从HARQ-ACK反馈延迟的范围中选择一个延迟值的情况，本申请避免了为了支持更低延迟在DCI中引入更多的比特开销；
-.对于通过RRC信令指示HARQ-ACK反馈延迟的情况，本申请配置多个与RNTI有关的HARQ-ACK反馈延迟的范围，解决了不同业务对延迟的不同要求。
