  • the peak-to-average ratio of the analog signal output has a certain relationship with the correlation between the set of discrete time domain data. Assume that a set of discrete time domain data signals y(n) is convolved with a set of time domain discrete data d(n) in the time domain to obtain yd(n):
  • PAPR1 and PAPR2 the peak-to-average ratios of the output signals of y(n) and yd(n) after passing through the DAC are PAPR1 and PAPR2 respectively. If d(n) is a set of designed weight coefficients, the correlation between adjacent data of yd(n) will be better than the correlation between adjacent data of y(n). The higher the correlation, the lower the PAPR, so PAPR2 will be smaller than PAPR1. After a set of discrete time domain data is convolved with a set of designed discrete data, PAPR can be effectively reduced.
  • the convolution operation of two time domain signals is equivalent to the dot product operation of the two time domain signals in the frequency domain. Therefore, a set of discrete time domain data is transformed into discrete frequency domain data after discrete Fourier transform (DFT), and then dot-multiplied with the designed spectrum shaping sequence, and then the time domain signal after inverse discrete Fourier transform (IDFT) can effectively reduce PAPR. Since the dot product operation is less complex than the convolution operation, this PAPR reduction technology operates better in the frequency domain, so this technology is called FDSS technology.

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端设备11和网络侧设备12。其中，终端设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端设备11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmission Reception Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function，PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、统一数据管理(Unified Data Management，UDM)，统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)，网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function，AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
本申请实施例提供的信号发射方法，可以在UE基于extension PRB进行信号发射的场景下，对MPR指标的资源块区域划分进行重新定义，终端设备可以根据重新划分的资源块区域对上行发射信号的MPR进行重新设定，进而基于重新设定的MPR发射上行发射信号。可以理解的是，终端设备基于重新设定的MPR发射上行发射信号时，可以在选定了波形、信道带宽、调制阶数等参数后，通过某些技术如FDSS技术，对 上行发射信号的性能，如峰均比(Peak Average Power Ratio，PAPR)等进行改善。示例性地，终端设备可以通过extension PRB的FDSS技术对上行发射信号进行上行发射功率增强。
FDSS是一种RAN4使用的频域赋形技术，可以有效降低PAPR，获得性能上的增益。一组离散时域信号经过数模转换器(Digital Analog Converter，DAC)后，其输出的模拟信号的峰均比与该组离散时域数据之间的相关性具有一定的关系。假设一组离散时域数据信号y(n)与一组时域离散数据d(n)进行时域卷积，获得yd(n):
设y(n)与yd(n)经过DAC后输出信号的峰均比分别为PAPR1和PAPR2，如果d(n)为一组设计好的权重系数的话，则yd(n)的相邻数据之间相关性会比y(n)的相邻数据之间相关性要好。相关性越高，PAPR越低，因此PAPR2会小于PAPR1，一组离散的时域数据与一组设计好的离散数据卷积后，能够有效降低PAPR。
根据卷积定理，两个时域信号的卷积操作可以等效于该两个时域信号在频域里的点乘操作。因此将一组离散时域数据经过离散傅里叶变换(Discrete Fourier Transform，DFT)之后变换成离散频域数据，然后点乘设计好的频谱成型序列，再经过离散傅里叶逆变换(Inverse Discrete Fourier Transform，IDFT)之后的时域信号就可以有效地降低PAPR。由于点乘操作比卷积操作复杂度低，这种降PAPR的技术在频域中操作更好，因此称这种技术为FDSS技术。
终端设备在利用FDSS技术对上行发射信号进行调制时，可以预留allocated PRB临近的PRB作为extension PRB，以调整上行发射信号的频域波形，获得较为平滑的波形，优化d(n)系数，降低PAPR。预留extension PRB主要有预留空间PRB和预留重复PRB这两种方式。
参照图2，示出了本申请实施例提供的一种基于预留空闲PRB的频谱成型示意图。如图2所示，在调度UE数据后，为其预留一些空闲PRB，也即extension PRB，供其将滤波器滚降旁瓣放入其中。相比于UE之间紧挨的方式，预留一些空闲PRB可以降低UE加窗的滚降幅度要求和截止频率要求，在滚降处实现更加平滑的下降，减少较为尖锐的抖动，可以获得更高的实际发送功率，获取更好的性能提升。
参照图3，示出了本申请实施例提供的一种基于重复PRB的频谱成型示意图。如图3所示，将传输数据PRB，也即allocated PRB的第一个PRB的内容进行重复并附加到传输数据PRB的最后，将传输数据PRB中的最后一个PRB的内容进行重复并附加到传输PRB之前，形成如图3所示的PRB带宽类型。这种方式相比于图2所示的方式，预留重复PRB在相关性上比预留空闲PRB的相关性更好，因此可能能够具有更好的性能提升。
需要说明的是，上述示例仅对UE基于extension PRB进行信号发射的场景下，对MPR指标的资源块区域划分进行重新定义，以及对上行发射信号的MPR进行重新设定之后，终端设备基于extension PRB，利用FDSS技术对上行发射信号的调制过程进行示例性说明。终端设备对上行发射信号进行重新设定之后，也可以基于extension PRB的配置信息以及重新设定的MPR，对上行发射信号进行其他处理，本申请实施例在此不做具体限定。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信号发射方法进行详细地说明。
第一方面，参照图4，示出了本申请实施例提供的一种信号发射方法的流程图。该方法应用于终端设备，如图4所示，该方法具体可以包括：
步骤401、终端设备基于第一参数划分最大功率回退指标的资源块区域，所述资 源块区域中包含分配物理资源块和扩展物理资源块；
步骤402、所述终端设备根据划分的资源块区域，重新设定上行发射信号的最大功率回退值；
步骤403、所述终端设备基于重新设定的最大功率回退值发射所述上行发射信号；
其中，所述第一参数包括以下任一项：
A1、分配物理资源块的配置信息；
A2、分配物理资源块的配置信息和扩展物理资源块的配置信息。
需要说明的是，所述终端设备可以是图1中的终端设备11，本申请实施例在此不再赘述。
在本申请实施例中，终端设备在划分MPR指标的资源块区域时，可以仅考虑allocated PRB的配置信息，也可以同时考虑allocated PRB的配置信息和extension PRB的配置信息。
可选地，所述分配物理资源块的配置信息包括分配物理资源块的起始位置和分配物理资源块的数目。
所述扩展物理资源块的配置信息包括：
扩展物理资源块的数目；或者，
扩展物理资源块的数目和扩展物理资源块的位置。
allocated PRB以资源块(Resource Block，RB)为单位，当allocated PRB包含多个RB时，这些RB是连续的。allocated PRB的起始位置为allocated PRB中的第一个RB的位置，allocated PRB的数目为allocated PRB中包含的连续RB的数目。
同样地，extension PRB以RB为单元，当extension PRB包含多个RB时，这些RB可以是连续的，也即连续分布在allocated PRB的一侧；或者，这些RB可以不连续，分布在allocated PRB的两侧。需要说明的是，extension PRB紧邻allocated PRB分布，且allocated PRB的任一侧的extension PRB中包含的RB是连续的。extension PRB的起始位置为extension PRB中的第一个RB的位置，extension PRB为紧邻allocated PRB的extension PRB中包含的RB的数目之和。示例性地，如果allocated PRB左侧的extension PRB中包含的RB的数目为x1，allocated PRB右侧的extension PRB中包含的RB的数目为x2，则extension PRB中包含的RB的数目，也即本申请中extension PRB的数目x＝x1+x2。其中，x1和x2可以均大于0，或者，x1和x2中有一项大于0，另一项等于0。
终端设备根据上述第一参数A1和A2中的任一项划分MPR指标的资源块区域。在本申请中，重新划分后的MPR指标的资源块区域中包含allocated PRB和extension PRB。相关技术中仅针对allocated PRB设定了MPR。因此，本申请在重新划分MPR指标的资源块区域之后，需要针对MPR指标的资源块区域中allocated PRB和extension PRB，重新设定上行发射信号的MPR值。进一步地，终端设备根据重新设定的MPR值发射上行发射信号，可以使得终端设备的上行发射信号在不同调制或信道带宽下具备较合适的功率，有利于提升上行发射信号的性能。
可选地，所述第一参数包括分配物理资源块的配置信息和扩展物理资源块的配置信息，所述终端设备基于第一参数划分最大功率回退指标的资源块区域，包括：在满足第一条件的情况下，所述终端设备基于第一参数划分最大功率回退指标的资源块区域。
其中，所述第一条件包括以下至少一项：

B4、扩展物理资源块的数目与分配物理资源块、扩展物理资源块的数目之和的比值大于第四阈值；
B5、所述终端设备的上行发射信号的调制阶数(Modulation order)或调制与编码策略(Modulation and Coding Scheme，MCS)指数小于第五阈值；
B6、所述终端设备的上行发射信号采用基于离散傅里叶变换的扩频正交频分复用(Discrete Fourier Transmission-Single Carrier-Orthogonal Frequency Division，DFT-S-OFDM)波形；
B7、所述终端设备采用低峰均比(low Peak Average Power Ratio，low PAPR)序列作为解调参考信号(Demodulation Reference Signal，DMRS)序列。
在本申请中，终端设备在划分MPR指标的资源块区域时，可以不考虑其他前提条件，直接基于A1或A2进行资源块区域划分；也可以在满足第一条件的情况下，也即满足上述B1至B7中的至少一项时，同时基于allocated PRB的配置信息和extension PRB的配置信息划分MPR指标的资源块区域。
需要说明的是，上述第一阈值、第二阈值、第三阈值、第四阈值和第五阈值，均可以由网络侧设备配置，或者，由协议规定。

其中，RBend为分配物理资源块的末端位置，RBEend为扩展物理资源块的末端位置；max(RBend，RBEend)表示取RBend与RBEend中的最大值。
若所述第一参数不满足第二条件和第三条件，则所述资源块区域属于外部区域。
在同时考虑allocated PRB的配置信息和extension PRB的配置信息的情况下，可以按照上述第二条件、第三条件，确定MPR指标的资源块区域在信道中所属的区域。具体地，如果allocated PRB与extension PRB的数目之和，也即allocated PRB与extension PRB中包含的RB的数目之和，小于或等于第一数值，且allocated PRB的起始位置与extension PRB的起始位置中的最小值，也即MPR指标的资源块区域的起始位置，大于或等于第二数值、小于或等于第三数值，则说明allocated PRB的配置信息和extension PRB的配置信息满足第二条件，MPR指标的资源块区域属于内部区域。

其中，第一数值、第二数值、第三数值和第四数值可以是固定值，也可以由协议规定。
作为一种示例，第一数值＝ceil(NRB/2)，第二数值＝max(1,floor(LCRB/2))，第三数值＝NRB–max(1,floor(LCRB/2))–LCRB；第四数值＝2，或者，所述第四数值由协议规定；
其中，NRB是给定信号带宽和子载波间距下的最大资源块数目，ceil(NRB/2)为大于或等于NRB/2的最小整数，floor(LCRB/2)为小于或等于LCRB/2的最大整数，max(1,floor(LCRB/2))表示取1和floor(LCRB/2)中的最大值。

若所述第一参数不满足第四条件和第五条件，则所述资源块区域属于外部区域。
在仅考虑allocated PRB的配置信息的情况下，可以按照上述第四条件、第五条件确定MPR指标的资源块区域在信道中所属的区域。具体地，如果allocated PRB的数目，也即allocated PRB中包含的RB的数目小于或等于ceil(NRB/2)，且allocated PRB的起始位置大于或等于1和floor(LCRB/2)中的最大值、小于或等于NRB–max(1,floor(LCRB/2))–LCRB，则说明allocated PRB的配置信息满足第四条件，MPR指标的资源块区域属于内部区域。
如果allocated PRB的数目小于等于2，且MPR指标的资源块区域位于信道带宽的最左端或最右端，则说明allocated PRB的配置信息满足第五条件，MPR指标的资源块区域属于边缘区域。
如果allocated PRB的配置信息既不满足第四条件，也不满足第五条件，则可以确定MPR指标的资源块区域属于外部区域。
需要说明的是，本申请实施例中，所述信道带宽包括系统带宽、部分系统带宽中的至少一项。

在本申请实施例中，MPR指标的资源块区域中，extension PRB的数目可以为固定 值，且extension PRB的数目与allocated PRB的数目之间不存在关联关系。或者，extension PRB的数目不固定，可以自适应调节，但是extension PRB的数目与allocated PRB的数目之间存在关联关系，例如，extension PRB的数目与allocated PRB的数目线性相关，或者满足其他函数关系。

在本申请实施例中，extension PRB的位置可以是固定的，extension PRB在allocated PRB的两侧呈对称式分布。
或者，extension PRB的位置不固定，可以根据allocated PRB的位置对extension PRB的位置进行自适应调节，extension PRB在allocated PRB的两侧呈非对称式分布。在这种情况下，allocated PRB的每一侧的extension PRB的数目，也即extension PRB中包含的RB的数目，均大于或等于1；或者，allocated PRB的某一侧的extension PRB的数目等于0，另一侧的extension PRB的数目大于或等于1。
需要说明的是，无论extension PRB的位置满足D1至D3中的哪一项条件，extension PRB都需要紧邻allocated PRB。
作为一种示例，在同时考虑allocated PRB的配置信息和extension PRB的配置信息的情况下，假设allocated PRB的每一侧的extension PRB的数目都大于0，本申请对于MPR指标的资源块区域的划分方式可以如图5至图7所示。
