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案，特别是涉及支持π/2-BPSK或π/4-QPSK调制传输的方法和装置。
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)进行研究。在3GPP RAN#75次全会上通过了5G新空口技术(NR)的工作项目(WI，Working Item)的立项，开始对5G新空口技术进行标准化。
为了能够灵活适应多种不同的应用场景，未来的无线通信系统，特别是5G NR将可以支持多种数理结构(Numerology)，多种数理结构是指多种子载波间隔，多种符号时间长度，多种CP(Cyclic Prefix，循环前缀)长度等。另一方面，为了能够保证覆盖性能，特别是由于发射功率受限导致的上行覆盖的问题，在5G NR的WI标准化过程中同意支持低PAPR(Peak to Average Power Ratio，峰均比)或CM(Cubic Matric，立方参数)的SC-FDMA，(Single Carrier Frequency Division Multiple Acess，单载波频分复用多址接入)波形(Waveform)，同时对于DFT-s-OFDM波形还支持π/2-BPSK的调制方式来进一步降低PAPR或CM，从而提高上行传输的覆盖性能和功率放大器的效率。
发明内容
π/2-BPSK调制和π/4-QPSK是分别通过对传统的BPSK和QPSK进行符号间的相位旋转来实现的，这种相位旋转可以尽量保证调制出的符号的相位的连续性和恒包络的属性，即使在经过滤波后(或冲击赋型，Pulse Shaping)后还能保证调制后的信号的低PAPR，提高覆盖的性能。SC-FDMA系统虽然一定程度上保留了单载波的属性，但是由于在实现中变换预编码(一般由DFT实现，即DFT-s-OFDM)或滤波的采用，本质上还是类似于OFDM的多载波形式，同时为了抵抗多径干扰，在每个多载波符号之前插入了循环前缀(CP)。这种DFT-s-OFDM波形的生成和CP的插入都会影响π/2-BPSK调制或π/4-QPSK调制下的基带信号的相位连续性和恒包络属性，从而使PAPR或CM上升，大大抵消了π/2-BPSK调制或π/4-QPSK调制所带来的覆盖性能的提升。
为了解决上述π/2-BPSK调制或π/4-QPSK调制在DFT-s-OFDM波形下面临的问题，本发明提供了解决方案。需要说明的是，在不冲突的情况下，本申请的UE(User Equipment，用户设备)中的实施例和实施例中的特征可以应用到基站中，反之亦然。进一步的，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。

作为一个实施例，本申请中的方法具有如下优点：
-本申请中提供一种时域的相位补偿的方法：在进行变换预编码(Transform Precoding，一般由DFT变换实现)之前，根据资源映射的时候的CP的长度对调制后(如果进行DFT前的多天线发射分集，则在发射分集的预编码之后)的信号依据信号的频率(一般为中心频率)对每个多载波符号上的相位进行补偿，在保持了信号的单载波特性的同时，保证了相位的连续变化，降低了PAPR，提高了覆盖性能。
-该时域相位补偿的方法也同时适用于通过频率变换和滤波产生的SC-FDMA信号，为实现提供了更多的灵活性。
-本申请还提供了一种频域相位补偿的方法：在DFT变换之后，IFFT变换生成基带信号之前，在每个子载波上依据各个子载波上的CP长度和子载波的频率对相位进行补偿，使用该频域相位补偿的方法也能够达到降低PAPR的效果。
-本申请中的相位补偿方法还同时考虑了上行跳频传输，由于参考信号的插入导致数据不连续等情况，通过精巧的设计(比如在跳频开始对相位补偿进行重置和假设参考信号也应用相同的相位补偿等)，进一步保证了SC-FDMA传输的低PAPR，提高了覆盖性能。
