Description

无线信号传输方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种无线信号传输方法及装置。
背景技术
新一代移动通信系统(new radio，简称为NR)需要支持增强移动宽带(enhanced mobile broad band，简称为eMBB)、高可靠低时延通信(Ultra-Reliable and Low-Latency Communications，简称为URLLC)以及海量机器类型通信(massive machine type communication，简称为mMTC)业务，而且将会在低于6GHz或者高于6GHz的更高的载波频率上进行系统组网，目前得到业界广泛共识和国际组织认定的频段主要是3GHz～6GHz，6GHz～100GHz，这一频段基本上属于厘米波段和毫米波段。研究表明，频率在6G～100GHz之间，特别是较高频率，射频器件的相位噪声非常严重，而增加正交频分多址系统的子载波宽度可以抵抗相位噪声。高频传播特性与较低频段有明显区别，由于高频段的传播损耗明显大于低频段，高频段的覆盖一般远小于低频段的覆盖范围，较小的覆盖范围一般情况下信道的延时扩展也比较小，相应的相干带宽比在300M～3000M的低频段的相干带宽要大，子载波宽度相对于长期演进(Long Term Evolution，简称为LTE)系统增加后仍然可以满足子载波间隔在相干带宽内这一设计要求。所以子载波间距(sub-carrier spacing，简称为SCS)(等同于子载波宽度)需要根据载波的高低进行调整，而且调整的可行性是存在且合理的。
新一代无线NR系统覆盖了从6G以下(sub 6G)一直到100G的载波频率，需要使用不同的子载波间距的帧结构参数来适应载波频率，也就是说各个载波频率上的帧结构设计参数会有所不同，举例来说，频率越接近LTE的核心频率，其子载波间隔等典型帧结构参数越接近LTE现有的参数，频率越高，其子载波间隔就越大。
不仅是系统在不同的频率上帧结构参数会有不同，即使NR系统在同 一个载波上，其传输业务类型的不同，不同类型业务的子载波间隔参数也会有所区别，比如说URLLC的业务强调低延时，相应的符号比eMBB更短，子载波间隔也大于eMBB，而mMTC业务需求偏向于海量接入和深度覆盖，其子载波间隔可能远远小于eMBB业务，符号长度也比eMBB大得多。多种类型的业务复用在同一载波上，使得系统帧结构参数更加的复杂。
子载波间隔SCS这一重要帧结构参数变化后，会相应的影响类似OFDM等多址系统的符号的长度以及循环前缀(Cyclic Prefix，简称为CP)的长度等。
一种常规的处理方法，是以LTE目前的帧结构为基础，进行可伸缩的帧结构参数变化，这种变化称为可Scalable。比如目前正在研究的子载波间距从15KHz、30KHz、60KHz、75KHz、120KHz一直到240KHz等或者比15KHz还要小的情况都是可能存在的，而且以上参数都是按照整数倍伸缩系数进行变化的。但是由于LTE帧结构参数的特殊性，即LTE的0.5ms的时隙中7个符号中第一个符号是长符号，其他6个符号是短符号，所以一般为了保证和时分(Time Division，简称为TD)LTE系统共存，帧结构参数伸缩一般是以一个时间间隔单元(Interval)(通常是1ms的子帧)长度为基础进行的，这样可以保证NR系统与TD-LTE系统以1ms为边界对齐，避免共存时带来的上下行相互干扰。
然而，当NR系统的帧结构参数伸缩以1ms的子帧长度为基础进行时，由于LTE时隙是由1个长符号和6个短符号组成的，所以在进行整数倍伸缩时，不同的子载波间隔参数对应的帧结构在符号边缘不能对齐。图1是根据相关技术中不同子载波间隔参数对应的帧结构示意图，图1中是以1ms为基础伸缩，不同参数的帧结构之间符号无法对齐。如图1所示，15KHz的LTE时隙有7个符号，子载波间隔调整为30KHz时，同样的0.5ms内是由原1ms的子帧的14个符号压缩1倍形成的，可以通过简单计算得出，15KHz的第一个符号末尾和30KHz的第1、2个符号的末尾是对不齐的，差距是8Ts，约0.26us。
图2是根据相关技术中符号未对齐时的上下行干扰示意图，当系统中出现了多套帧结构参数以频分复用(Frequency Division Multiplexing，简称为FDM)的方式共存时，如图2的15KHz和30KHz两套帧结构参数共存时，如果采用的是时分双工(Time Division Duplexing，简称为TDD)双工方式，TDD的上下行切换点在整数个符号长度单位的情况下，比如15KHz帧结构下的第2符号是下行，30KHz帧结构下的第3、4符号是下行，第5个符号是上行，15KHz帧结构下的第2符号会在第2符号末尾的边缘也就是对不齐的位置干扰30KHz帧结构下第5个符号。
针对相关技术中存在不同子载波间隔参数时容易产生符号未对齐的情况，进而会导致上下行干扰的问题，目前尚未给出有效的解决方案。

下面结合优选实施例进行说明，以下优选实施例结合了上述实施例及其优选实施方式。
优选实施例
实施例一
符号为循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing，简称为CP-OFDM)符号，描述CP-OFDM的参数有多套，同一套参数内的有效符号(即承载有效数据(不包含CP)的OFDM符号部分，也称净载荷)等长，同一套参数内前缀CP有两种可能的长度，分别定义为长CP和短CP，其中，长CP的长度大于短CP的长度；多套参数间的有效符号长度，前缀CP不相等，如果满足伸缩原则，且伸缩因子Scale factor＝m，则伸缩后的子载波间隔fs下的有效符号长度及长短CP长度(一套参数)为基础子载波间隔f0下的(另一套参数)1/m。其中m可以为大于等于1的正整数，也可以是1/2，1/3，1/4等分子为1、分母为正整数的分数。
同一套参数内符号级联组合成符号级联块发射，块内(块内只包含下行链路部分DL Part或上行链路部分UL Part)由多个CP-OFDM符号组成，块内符号最多不超过基础帧结构(子载波间隔为f0)的子帧或时隙总的符号数。
块内每个符号之间的长度相对比例，和基础帧结构参数下的块内每个符号之间的长度相对比例相同，如果是只有长符号和短符号两种长度，则长符号和短符号的长度相对比例和基础帧结构参数下的长符号和短符号之间的长度相对比例相同。
多套参数间在同一时间段内对应的m个符号级联块的长度一致。
图4是根据本发明优选实施例一的符号级联成块后进行伸缩的示意图，如图4所示，假设基础子载波间隔为f0(对应一套配置或参数，包括该子载波间隔下的有效符号长度，前缀CP等)，下行和上行部分分别是2个符号，伸缩后的子载波间隔是fs＝2*f0(对应另一套配置或参数，包括该子载波间隔下的有效符号长度，前缀CP等)，伸缩后这一套配置的符号长度为基础子载波间隔对应的那一套配置的符号长度的1/2，下行和上行分别是4个符号。对基础帧结构的2个符号级联成块(即符号级联块)然后进行时间压缩后，压缩比例为1/2，呈现的图样参见图4，基础帧结构f0的第1和第2符号是长CP和短CP的图样，则压缩后的同一时间段内，压缩的帧结构为压缩后的长CP-OFDM+短CP-OFDM的2个符号级联成的符号级联块再加另外一个长CP-OFDM+短CP-OFDM级联成的符号级联块进行组合的形式。基础帧结构的第3和第4符号是短CP和短CP的图样，则压缩后的帧结构为短CP-OFDM+短CP-OFDM+短CP-OFDM+短CP-OFDM的组合。其中fs下的长CP-OFDM、短CP-OFDM的长度相对比例与f0下的相同，且长CP-OFDM+短CP-OFDM+长CP-OFDM+短CP-OFDM的符号级联块(符号1、2、3、4)，再进行组合的总长度和基础帧结构f0的符号并级块(符号1、2)的长度相同。
通俗的说，上述方案中的NR系统依据不同伸缩因子scaling factor进行伸缩时，基于特定DL、GP、UL part长度基准进行伸缩，即伸缩不改变各部分基准类型，从而解决了相关技术中存在不同子载波间隔参数时容易产生符号未对齐的情况，进而会导致上下行干扰的问题，避免了上下行干扰，提升了系统健壮性及稳定性。
实施例二
前面的实施例重点以解决上下行互相干扰为目的进行的对齐，解决方案也是考虑对相同传输方向的多符号组成的级联块进行对齐。下面这个实施例主要是从多符号的功能归一化角度出发考虑问题。
符号仍然为CP-OFDM符号，描述CP-OFDM的参数有多套，同一套 参数内的有效符号(不包含CP)的部分等长，同一套参数内前缀CP有两种可能的长度，分别定义为长CP和短CP，其中，长CP的长度大于短CP的长度；多套参数间的有效符号长度，前缀CP不相等，如果满足伸缩原则，且伸缩因子(Scale factor)＝m，则伸缩后的子载波间隔fs下的有效符号长度及长短CP长度(一套参数)为基础子载波间隔f0下的(另一套参数)1/m。其中m可以为大于等于1的正整数，也可以是1/2，1/3，1/4等分子为1、分母为正整数的分数。
同一套参数内执行相同功能的符号级联组合成符号级联块发射，比如只执行下行控制信息承载的符号级联块，只执行下行数据承载的符号级联块，只执行上行控制信息承载的符号级联块，只执行上行数据承载的符号级联块等。块内由1个或多个CP-OFDM符号组成，块内符号最多不超过基础帧结构(子载波间隔为f0)的子帧或时隙总的符号数。
块内每个符号之间的长度相对比例，和基础帧结构参数下的块内每个符号之间的长度相对比例相同，如果是只有长符号和短符号两种长度，则长符号和短符号的长度相对比例和基础帧结构参数下的长符号和短符号之间的长度相对比例相同。
图5是根据本发明优选实施例二的符号级联成块后进行伸缩的示意图，假设基础子载波间隔为f0(对应一套配置或参数，包括该子载波间隔下的有效符号长度，前缀CP等)，下行和上行部分分别是2个符号，即下行控制Ctrl和下行数据Data各1个符号，上行控制Ctrl和上行数据Data各1个符号。伸缩后的子载波间隔是fs＝2*f0(对应另一套配置或参数，包括该子载波间隔下的有效符号长度，前缀CP等)，伸缩后这一套配置的符号长度为基础子载波间隔对应的那一套配置的符号长度的1/2。对基础帧结构的1个符号级联成块(即符号级联块)然后进行时间压缩后，压缩比例为1/2，呈现的图样参见图5，基础帧结构f0的第1符号(第1块)是长CP的图样，则压缩后的同一时间段内，压缩的帧结构为压缩后的长CP-OFDM+长CP-OFDM的2个符号级联成的符号级联块。基础帧结构f0的第2符号是短CP的图样，则压缩后的同一时间段内，压缩的帧结构为 压缩后的短CP-OFDM+短CP-OFDM的2个符号级联成的符号级联块。基础帧结构的第3符号是短CP图样，则压缩后的帧结构为短CP-OFDM+短CP-OFDM的组合。基础帧结构的第4符号是短CP的图样，则压缩后的帧结构也为短CP-OFDM+短CP-OFDM的组合。其中fs下的长CP-OFDM、短CP-OFDM的长度相对比例与f0下的相同，且长CP-OFDM+短CP-OFDM+长CP-OFDM+短CP-OFDM的符号级联块为符号1+2、3+4、5+6、7+8，分别表示下行控制、下行数据、上行数据、上行控制，这些功能块分别和基础帧结构f0的符号并级块(符号1、2、3、4)各自的长度相同。功能块的组合的总长度和基础帧结构f0的符号并级块(符号1、2、3、4)的总长度相同。
从图5中可以归纳出，对齐的级联块之间存在这样的相对关系：具有大子载波间隔(符号较短)的级联块中x个符号的长度的相对关系(即长、短、短…关系)与小子载波间隔(符号较长)中y个符号的长度的相对关系相同，这里x＝scaling factor×y。具体来说小子载波间隔的符号如果为长符号，则对应的大子载波间隔的scaling factor个符号也为长符号，小子载波间隔的符号如果为短符号，则对应的大子载波间隔的scaling factor个符号也为短符号。从这个实施例可以看出，如果小子载波间隔的级联块中有一个符号为长符号，则对应的大子载波间隔的级联块中至少也有一个符号为长符号。
通俗的说，上述方案中的NR系统依据不同伸缩因子scaling factor进行伸缩时，基于特定功能，比如控制、数据部分的长度基准进行伸缩，即伸缩不改变各部分基准类型功能，从而解决了相关技术中存在不同子载波间隔参数时容易产生符号未对齐的情况，进而会导致功能块之间相互干扰的问题，提升了系统健壮性及稳定性。
