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
3GPP(3rd Generation Partner Project，第三代合作伙伴项目)LTE(Long-term Evolution，长期演进)Release 13及Release 14在蜂窝系统中引入了非授权频谱通信。为保证和其它非授权频谱上的接入技术兼容，LBT(Listen Before Talk，会话前侦听)技术被LTE的LAA(Licensed Assisted Access，授权频谱辅助接入)采纳以避免因多个发射机同时占用相同的频率资源而带来的干扰。LTE系统中LBT是宽带的，即LBT的带宽与CC(Component Carrier)的带宽通常是相同的。在5G NR(New Radio Access Technology，新无线接入技术)Phase 1(阶段1)系统中，为了更好的支持不同接收带宽和发送带宽能力的UE(User Equipment，用户设备)，在一个CC中引入了BWP(Bandwidth Part，频带部分)的概念。当带宽能力较大的UE与小区通信时，所述UE可以在带宽较大的BWP上进行下行接收或上行发送。NR Release 16关于非授权频谱的接入技术正在讨论中，目前已经同意采纳子带(Subband)LBT，子带LBT的带宽是20MHz的整数倍，子带LBT的带宽可以等于或者小于BWP的带宽。
在无线通信系统中，参考信号一直是保证通信质量的必要手段之一。在高频段，相位噪声对信道估计性能的影响不容忽视，在NR R15中，PTRS(Phase-Tracking Reference Signal，相位跟踪参考信号)被接收端用于相位跟踪，通过在信道估计中进行相位补偿来提升信道估计精度。
发明内容
发明人通过研究发现，相比LTE系统的宽带LBT，NR系统采用子带LBT可以提高信道接入机会，但是也导致了实际占用资源的不确定性，在这种情况下如何设计PTRS是需要考虑的一个关键问题。
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，所述第一信令指示N1个时频资源块；
在N个时频资源块中分别操作N个无线信号；
其中，所述N1个时频资源块在频域上分别属于N1个子频带,所述N1个子频带中的任意两个子频带都正交，N1是大于1的正整数；所述N个时频资源块中的任一时频资源块都是所述N1个时频资源块中之一，N是大于1且不大于所述N1的正整数；所述N个无线信号分别包括N个第一类参考信号，所述N个第一类参考信号的发送天线端口都与第一天线端口相关联；第一目标信号是所述N个第一类参考信号中的任一第一类参考信号，所述第一目标信号的频域密度和所述N1个时频资源块中的仅目标时频资源块有关，所述目标时频资源块是所述N1个时频资源块中之一；所述操作是发送，或者，所述操作是接收。
作为一个实施例，本申请要解决的问题是：子带LBT下的PTRS设计是需要被研究的一个关键问题。
作为一个实施例，本申请要解决的问题是：现有NR标准中，PDSCH/PUSCH的调度带宽(Scheduled Bandwidth)被用于确定PTRS的频域密度，调度带宽越小，PTRS的频域 密度可能越小(即频域分布越密集)，在宽带LBT情况下实际占用带宽和调度带宽相同；但是，在子带LBT下，当一个PDSCH/PUSCH的调度时频资源包括多个子带上的时频资源时，由于信道占用的不确定性，实际占用带宽可能是小于调度带宽的，在这种情况下如何确定PTRS的频域密度是需要被重新考虑的一个关键问题。
作为一个实施例，上述方法的实质在于，N1个时频资源块是调度给PDSCH/PUSCH的时频资源，N1个子频带是N1个子带，N1个子带中只有N个子带的信道是空闲的，因此PDSCH/PUSCH在N1个时频资源块中的仅N个时频资源块中被发送，N个第一类参考信号分别是N个时频资源块中的PTRS；一个时频资源块中的PTRS的频域密度和N1个时频资源块中的仅一个时频资源块有关。采用上述方法的好处在于，所提的PTRS的频域密度的确定方法与实际占用带宽无关或者子带LBT的结果无关，因此保证了各种子带LBT结果下的收发端关于PTRS频域密度的理解的一致性，保证了PDSCH/PUSCH的传输可靠性。
根据本申请的一个方面，上述方法的特征在于，所述N个无线信号还分别包括N个解调参考信号，所述N个第一类参考信号的发送天线端口都相同，所述N个解调参考信号的发送天线端口都相同，所述第一天线端口是所述N个解调参考信号的一个发送天线端口。

作为一个实施例，上述方法的实质在于，一个时频资源块中的PTRS的频域密度仅和该PTRS所属的一个时频资源块有关。采用上述方法的好处在于，保证了各种子带LBT结果下的PTRS相位跟踪的准确性，保证了PDSCH/PUSCH的传输可靠性。
作为一个实施例，上述方法的实质在于，一个时频资源块中的PTRS的频域密度仅和N1个时频资源块中带宽最小的一个时频资源块有关，因此N个时频资源块中的PTRS的频域密度都相同。采用上述方法的好处在于，保证了各种子带LBT结果下的PTRS相位跟踪的准确性，保证了PDSCH/PUSCH的传输可靠性。
根据本申请的一个方面，上述方法的特征在于，包括：

根据本申请的一个方面，上述方法的特征在于，所述N1个时频资源块中的任一时频资源块包括正整数个时频资源单元，所述N1个时频资源块中的任意两个时频资源单元在频域上都正交；第一时频资源块是所述N个时频资源块中包括所述第一目标信号所占用的时频资源的一个时频资源块，所述第一时频资源块包括M1个时频资源单元，所述第一目标信号所占用的所述时频资源属于所述M1个时频资源单元中的仅M2个时频资源单元；所述目标时频资源块包括的所述时频资源单元的数量和所述第一目标信号的所述频域密度被用于从所述M1个时频资源单元中确定所述M2个时频资源单元；M1是正整数，M2是不大于所述M1的正整数。
作为一个实施例，上述方法的实质在于，N个时频资源块中的PTRS的频域分布分别是独立确定的。
根据本申请的一个方面，上述方法的特征在于，所述N1个时频资源块中的任一时频 资源块包括正整数个时频资源单元，所述N1个时频资源块中的任意两个时频资源单元在频域上都正交；所述N大于1，第二时频资源块和第三时频资源块是所述N个时频资源块中的任意两个在频域上相邻的时频资源块，所述第三时频资源块的频率高于所述第二时频资源块的频率，第二目标信号和第三目标信号分别是所述N个第一类参考信号中分别在所述第二时频资源块和所述第三时频资源块中被发送的第一类参考信号；所述第二时频资源块包括S1个时频资源单元，所述第二目标信号所占用的所述时频资源属于所述S1个时频资源单元中的仅S2个时频资源单元；所述第三时频资源块包括T1个时频资源单元，所述第三目标信号所占用的所述时频资源属于所述T1个时频资源单元中的仅T2个时频资源单元；所述S2个时频资源单元中频率最高的一个时频资源单元和所述第三目标信号的频域密度被用于从所述T1个时频资源单元中确定所述T2个时频资源单元。
