具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本实施例中提供的控制器可执行本申请任意实施例所提供的码率调整方法，具备执行该方法相应的功能模块。未在本实施例中详尽描述的技术细节，可参见本申请任意实施例所提供的码率调整方法。
值得注意的是，上述码率调整装置的实施例中，所包括的各个单元和模块只是按照功能逻辑进行划分的，但并不局限于上述的划分，只要能够实现相应的功能即可；另外，各功能单元的具体名称也只是为了便于相互区分，并不用于限制本申请的保护范围。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信技术(5th generation wireless systems，5G)系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站 eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(transmission reference point，TRP)等，本申请实施例并不限定。在本申请中以5G基站为例进行说明。
本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
高频场景中相位噪声比较大，即使接收端做了相位补偿，也会残留很多的相位噪声。同时，高频场景中多普勒频移比较大，即使接收端做了频偏补偿，数据符号里也会残留一些的相位偏差。特别是对于一些低级终端，由于器件成本低，性能差，因此相位噪声会更大。
另外高频场景中，路损和阴影衰弱也比较大，因此在小区边缘有些区域的信噪比会非常低。而且高频时放大器(Power Amplifier，PA)的效率比较低，为了提高信噪比，同时也要节省用户设备(User Equipment，UE)电池的功耗，就需要UE发射信号的峰均比PAPR比较低。目前5G NR标准里，为了发送更低PAPR的信号，通常会选用离散傅里叶变换扩展正交频分复用(Discrete Fourier  Transform-Spread OFDM，DFT-sOFDM)波形，由于其数据是在时域上映射的，使得PAPR会低于循环前缀正交频分复用(Cyclic Prefix-Orthogonal Frequency Division Multiplexing，CP-OFDM)。
目前NR协议中单载波的PTRS主要是以分组均匀插入的方式进行配置，这种配置方式较为单一。综上所述，需要考虑在不影响系统频谱效率又使PAPR较低的情况下，如何来抑制相位噪声的影响，因此需要设计新的PTRS配置方案来解决这个问题。
针对上述问题，本申请实施例提供如下技术方案。
在一个实施例中，提供一种PTRS配置方法，所述PTRS配置方法适用于在高频场景中抑制相位噪声的情况。如图1所示，本申请实施例提供的信息指示方法主要包括步骤S11、S12。
S11、在时域符号内非均匀配置至少两个相位跟踪参考信号PTRS块，其中，每个PTRS块中均包括一个或多个PTRS。
S12、将配置好的PTRS发送至第二节点。
在本实施例中，上述第一节点是指5G系统中的发送端，所述发送端可以是上述任意一个基站或者用户设备。第二节点是是指5G系统中的接收端，所述接收端可以是上述任意一个基站或者用户设备。
在一个示例性的实施方式中，所述至少两个相位跟踪参考信号PTRS块包括：第一PTRS块和第二PTRS块。
在一个示例性的实施方式中，所述至少两个相位跟踪参考信号PTRS块包括：第一PTRS块、第二PTRS块和第三PTRS块。
在本实施例中，PTRS块是指由多个连续PTRS构成的信号块，或者也可以称为PTRS组。进一步的，第一PTRS块可以理解为首部PTRS块，即配置在时域符号首部的一系列连续的PTRS，第二PTRS块可以理解为尾部PTRS块，即配置在时域符号尾部的一系列连续的PTRS。第三PTRS块可以理解为中间PTRS块，即配置在时域符号中间的一系列连续的PTRS。
在一个实施方式中，在时域符号内非均匀配置首部PTRS块和尾部PTRS块。
在另一个实施方式中，在时域符号内非均匀配置首部PTRS块、中间PTRS块和尾部PTRS块。即中间PTRS块可以根据实际情况配置或者不配置。
在一个示例性的实施方式中，所述第一PTRS块配置在所述时域符号的首部，所述第二PTRS块配置在所述时域符号的尾部。
在一个示例性的实施方式中，所述第一PTRS块内的PTRS和第二PTRS块内的PTRS均是连续排列的。
在一个示例性的实施方式中，当预设时域范围内包括多个时域符号，则每个时域符号内的所述第一PTRS块中PTRS序列相同，每个时域符号内的所述第二PTRS块中PTRS序列相同。
在一个示例性的实施方式中，第一PTRS块中PTRS序列与时域参考信号的首部序列相同；第二PTRS块中PTRS序列与时域参考信号的尾部序列相同。
在一个示例性的实施方式中，当所述参考信号是在频域定义，则第一PTRS块中PTRS序列与频域参考信号经过快速傅里叶逆变换(Inverse Fast Fourier Transform，IFFT)后的时域参考信号的首部序列相同，第二PTRS块中PTRS序列与频域参考信号经过IFFT后的时域参考信号的尾部序列相同。
在时域内非均匀放置PTRS，每个符号内的PTRS分为首部PTRS块，中间PTRS块以及尾部PTRS块。进一步地，每个符号内的首部PTRS块和尾部PTRS块都是连续排列的。进一步地，在一定范围内，每个符号内的首部PTRS块序列都相同，每个符号内的尾部PTRS块序列相同，而中间的PTRS块不同。这样做的好处是，在可以使用PTRS进行相位噪声估计的同时，可以利用首尾序列达到循环前缀(Cyclic Prefix，CP)的效果，以达到抵抗多径时延的效果。在可以使用PTRS进行相位噪声估计的同时，可以利用首尾序列达到CP的效果，以达到抵抗多径时延的效果。
在一个示例性的实施方式中，所述第一PTRS块内PTRS个数与时域符号长度成正比；所述第二PTRS块内PTRS个数由衰落信道多径时延确定。
首部PTRS个数与符号长度成正比，尾部PTRS个数与衰落信道多径时延有关；这样可以根据信道环境配置具有CP作用效果的首尾PTRS。
在一个示例性的实施方式中，所述第二PTRS块内PTRS个数大于所述第一PTRS块内PTRS个数。
在一个示例性的实施方式中，所述第三PTRS块中的PTRS离散分布在所述时域符号的数据中。
在一个示例性的实施方式中，所述第三PTRS块中的PTRS均匀分布在除第一PTRS块和第二PTRS块之外的所述时域符号的数据中。
在一个示例性的实施方式中，在第三PTRS块中包括多个PTRS的情况下，所述第三PTRS块内包括长度相同的一个或多个子块，每个所述子块内均包括一个或多个PTRS；
其中，每个所述子块在时域数据中均匀分布。
在一个示例性的实施方式中，一个所述第三PTRS块内包括的子块的数量和每个子块内PTRS数量均由以下一个或多个参数确定：数据受到的相位噪声的大小及变化速度，高斯白噪声的大小及变化速度。
中间PTRS块分成的子块块数A以及每个子块内的PTRS个数B为某一设定值，且该设定值通常与数据受到的相位噪声及高斯白噪声的大小和变化速度有关。这样根据实际环境的相位噪声和加性高斯白噪声(Additive White Gaussian Noise，AWGN)，可以灵活的配置PTRS，保证高的资源利用率的同时可以很好的补偿相位噪声。
在一个示例性的实施方式中，所述第三PTRS块中的PTRS序列调制方式与所述时域符号内的数据调制方式相同。
首尾PTRS序列与参考信号序列相同，中间的PTRS序列的调制方式与数据符号的调制方式相同。这样做的好处是，可以降低整体的PAPR。
在一个示例性的实施方式中，所述调制方式包括如下一个或多个：二进制相移键控(Binary Phase Shift Keying，BPSK)调制方式，pi/2BPSK调制方式，正 交相移键控(Quadrature Phase Shift Keying,QPSK)调制方式、正交幅度调制(Quadrature Amplitude Modulation，16QAM)方式。
如果参考信号是在频域定义的，则首尾PTRS序列与频域的参考信号经过IFFT后的时域参考信号的首尾序列相同；进一步地，数据符号的调制方式为pi/2BPSK、BPSK、QPSK、16QAM等，中间的PTRS序列调制方式为pi/2BPSK、BPSK、QPSK、16QAM；这样不会因为数据中间插入了PTRS而破坏了原有的调制方式的低PAPR的特性。
本申请实施例提供的相位跟踪参考信号配置方法，通过在时域符号内非均匀配置至少两个相位跟踪参考信号PTRS块，其中，每个PTRS块中均包括一个或多个PTRS；将配置好的PTRS块发送至第二节点，实现了在不影响系统频谱效率且峰值平均功率比(Peak to Average Power Ratio，PAPR)较低的情况下，抑制相位噪声的影响。
在一个应用性的实施方式中，图2是本申请实施例提供的一个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，在首部和尾部分别配置一段连续的PTRS，中间部分为数据，不配置中间PTRS。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。
在一个应用性的实施方式中，图3是本申请实施例提供的不同时隙内两个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，中间部分为数据，不配置中间PTRS。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。由于第一个时隙内的OFDM符号长度为第二个时隙内的2倍，所以第一个OFDM符号的首部PTRS长度也设置为第二个符号的两倍，且尾部保持相同。
在一个应用性的实施方式中，图4是本申请实施例提供的不同时隙内两个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，中间部分为数据，不配置中间PTRS。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。由于第一个时隙内的OFDM符号与第二个时隙内的OFDM经历的信道的多径时延不同，即前者的多径时延大于后者，所以第一个OFDM符号的尾部PTRS长度设置为大于第二个符号的尾部，且首部保持相同。
在一个应用性的实施方式中，图5是本申请实施例提供的不同时隙内两个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，第一个OFDM符号中间为数据，不配置中间PTRS。第二个OFDM符号中间有一个中间PTRS块，A＝1。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。由于第一个时隙内的OFDM符号与第二个时隙内的OFDM经历的信道的噪声不同，即前者的噪声小于后者，所以第二个OFDM符号额外增加中间PTRS，而首尾PTRS相同。
在一个实施方式中，首尾PTRS调制方式和中间PTRS调制方式一样；在另一个实施方式中，首尾PTRS调制方式和中间PTRS调制方式不一样。
在一个应用性的实施方式中，图6是本申请实施例提供的不同时隙内两个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，第一个OFDM符号中间为数据，不配置中间PTRS，第二个OFDM符号中间有7个PTRS块，A＝7。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。由于第一个时隙内 的OFDM符号与第二个时隙内的OFDM受到的相位噪声不同，即前者的相位噪声小于后者，所以第二个OFDM符号额外增加了分组的中间PTRS，而首尾PTRS相同。
在一个实施方式中，中间PTRS也可以是非均匀分布的。
在一个应用性的实施方式中，图7是本申请实施例提供的同一时隙内1个OFDM符号和1个DMRS的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，中间为数据，不配置中间PTRS。DMRS内的首尾部分序列与OFDM数据符号内的PTRS首尾序列相同。首尾PTRS是DMRS符号的一部分。如果DMRS参考信号为频域产生，则时域参考信号为频域DMRS经过IFFT之后的时域序列。
在一个应用性的实施方式中，图8是本申请实施例提供的一个OFDM符号的PTRS配置方案的示意图，由于经历的信道为具有一定多径时延的衰落信道，并且在发送端和接收端有一定的相位噪声存在，则在首部和尾部分别有一段连续的PTRS，中间为数据，A＝7。并且同一时隙内其他OFDM符号的配置也如此，且每个符号的首尾的PTRS序列完全相同。数据调制方式为QPSK，中间PTRS也为QPSK调制。另外，中间PTRS调制也可以不与数据调制方式相同，即中间PTRS调制为固定某种调制，如pi/2BPSK，在发送端设定好，不随数据变化而变化。
在一个实施例中，提供一种PTRS配置装置，所述PTRS配置装置适用于在高频场景中抑制相位噪声的情况。如图9所示，本申请实施例提供的PTRS配置装置主要包括配置模块91、发送模块92。
配置模块91，被配置为在时域符号内非均匀配置至少两个相位跟踪参考信号PTRS块，其中，每个PTRS块中均包括一个或多个PTRS。
发送模块92，被配置为将配置好的PTRS发送至第二节点。
本申请实施例提供的相位跟踪参考信号配置方法，通过在时域符号内非均匀配置至少两个相位跟踪参考信号PTRS块，其中，每个PTRS块中均包括一个或多个PTRS；将配置好的PTRS块发送至第二节点，实现了在不影响系统频谱效率且峰值平均功率比(Peak to Average Power Ratio，PAPR)较低的情况下，抑制相位噪声的影响。

值得注意的是，上述PTRS配置装置的实施例中，所包括的各个单元和模块只是按照功能逻辑进行划分的，但并不局限于上述的划分，只要能够实现相应的功能即可；另外，各功能单元的具体名称也只是为了便于相互区分，并不用于限制本申请的保护范围。
