Description

一种数据帧实现方法和装置 技术领域
本发明涉及通信领域,尤其涉及一种数据帧实现方法和装置。
背景技术
目前随着通信技术的发展和用户需求的增长,界内都在研究5G移动通信,其中,5G移动通信除了支持传统的电信业务外,还需要更好地满足未来移动互联网和物联网业务的快速发展。因此,业界为5G移动通信提出了多样性的业务需要,包括高容量、短时延、大连接、高可靠、高速度等关键性能需求。且多样性的业务对系统数值参数的需求是不统一的,甚至是互斥的。例如高速移动用户需要较宽的子载波间隔以抵抗较高的多普勒扩展(Doppler Spread),而为了服务远距离用户又需要设计较较窄的子载波间隔以保证有效的相干带宽(Coherent Bandwidth)。然而,目前移动通信系统中的子帧具有完全相同的数据结构,如等子帧长度、等符号数、等子载波间隔,且对于相等的传输带宽采样频率和FFT大小都相等。可见,目前移动通信系统中子帧的这种单一化的特点,不能满足5G移动通信多样化的业务需求,从而导致5G移动通信的业务水平很低。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例中提供的数据帧实现方法可以应用于5G移动通信,由于业界为5G移动通信提出了多样性的业务需要,包括高容量、短时延、大连接、高可靠、高速度等关键性能需求。因此本发明实施例中配置用于无线信号传输的数据帧,该数据帧包括至少两个子帧,且每个所述子帧的长度固定,所述至少两个子帧可映射到子载波间隔不同的至少两个频带上,且每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应。这样本发明实施例中,可以实现数据帧可以包括不同的长度的子帧,从而该数据帧可以传输不同的业务,另外,由于数据帧可以映射到子载波间隔不同的至少两个频带上,这样该数据帧可以应用于不同的应用场景,可以满足5G移动通信多样化的业务需求,以提高5G移动通信的业务水平。
请参阅图1,图1是本发明实施例提供的一种数据帧实现方法的流程示意图,如图1包括以下步骤:
101、发送机配置用于无线信号传输的数据帧,所述数据帧包括至少两个子帧,每个所述子帧的长度固定,所述至少两个子帧可映射到子载波间隔不同的至少两个频带上,且每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应。
本实施例中,上述数据帧包括至少两个子帧可以理解为上述数据帧可以包括两个或者两个以上的子帧。且数据帧包括的子帧可以是长度不同的子帧,或者长度相同的子帧。
另外,上述每个所述子帧的长度固定可以理解为,每个子帧的长度是不可变,但上述数据帧中可以包括长度不相同的多个子帧,或者可以包括长度相同的多个子帧,或者可以包括部分子帧的长度相同,部分子帧的长度不相同。
另外,上述至少两个子帧可映射到子载波间隔不同的至少两个频带上可以 理解为,上述至少两子帧拥有能够映射到子载波间隔不同的至少两个频带上的能力,或者可以理解为,上述至少两子帧允许映射到子载波间隔不同的至少两个频带上。这样上述数据帧就可以映射到子载波间隔不同的至少两个频带上,例如:可以根据不同的应用场景将上述数据帧映射到子载波间隔不同的频带上。另外,上述映射可以理解为上述至少两个子帧可以在子载波间隔不同的至少两个频带上传输。
另外,上述每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应可以理解为,每个子帧包括的符号的数量可以随映射到的频带的子载波间隔变化。例如:如图2所示,上述数据帧中的第一子帧映射到子载波间隔为15kHz的频带上时,第一子帧只包括一个符号,即第一子帧的符号数量为1,另外,在该情况下,第一子帧包括一个循环前缀(Cyclic Prefix,CP),其中,第一子帧长度为71.87us,或者理解为第一子帧的传输时间间隔(Transmission Time Interval,TTI)为71.87us,其中,符号(Symbol)的长度为66.67us,CP的长度为5.20us。如图3所示,上述数据帧的第一子帧映射到子载波间隔为30kHz的频带上时,第一子帧包括两个符号,即第一子帧的符号数量为2,第一子帧包括两个CP,且第一子帧的长度为71.87us,每个符号(Symbol)长度为33.33us,每个CP为2.60us。如图4所示,上述数据帧的第一子帧映射到子载波间隔为60kHz的频带上时,第一子帧包括四个符号,即第一子帧的符号数量为4,第一子帧包括四个CP,且第一子帧的长度为71.87us,每个符号(Symbol)长度为16.67us,每个CP为1.30us。
本实施例中,上述至少两个子帧可以包括第一长度的第一子帧;
当所述第一子帧被映射到第一子载波间隔的频带上时,所述第一子帧包括至少一个符号;
当所述第一子帧被映射到第二子载波间隔的频带上时,所述第一子帧包括至少两个符号,所述第二子载波间隔的大于所述第一子载波间隔。
其中,上述第一长度可以是预先设定的,例如:设置第一长度为4G或者3G或者2G系统中一个符号长度和一个CP长度之积,例如:第一长度=TL0=传统符号长度(Legacy-Symbol)66.67us+传统CP(Legacy-CP)5.2us=71.87us。 当然,本实施例中,上述第一长度还可以是其他长度,例如两个TL0长度等,对此本实施例不作限定。
其中,参考图2至图4,以第一长度为71.87us为例进行举例说明,这样通过图2至图4可以清楚地知道,第一子帧映射到不同的频带上时,包括的符号数量都是不同的。且由于第一子帧的长度可以设置比较短,从而本实施例中,还可以定义第一子帧为超短子帧。另外,由于第一子帧内的符号和CP的长度是可以灵活变化的,这样当符号和CP长度越长,可支持更大的多径时延,且子载波间隔越大,可容忍多普勒扩展越大。因此图2所示的超短子帧数据结构可在广覆盖的场景下满足低时延需求,而图4所示的超短子帧数据结构可在高速移动的场景下满足时延需求。
另外,针对上述第一子帧还可以参考图5,在图5中给出了第一子帧在不同带宽下的数值参数,其中,选项1表示图2所示的场景,即第一子帧映射在子载波间隔为15kHz的频带上,选项2表示图3所示的场景,即第一子帧映射在子载波间隔为30kHz的频带上,选项3表示图4所示的场景,即第一子帧映射在子载波间隔为60kHz的频带上△f为子载波间隔,Tu表示符号的长度,FFT大小快速傅氏变换(Fast Fourier Transformation,FFT size)。通过图5所示的表格,可知,第一子帧映射到不同的频带上时,包括的符号数量都是不同的,从而满足5G移动通信多样化的业务需求。另外,通过图5可知,长度固定的帧具有符号数不同,但CP开销保持一致的特点,从而可以节约网络传输资源。
本实施例中,上述至少两个子帧可以包括第二长度的第二子帧,其中,所述第二长度等于N倍所述第一长度,所述N为大于1的正整数;
当所述第二子帧被映射到所述第一子载波间隔的频带上时,所述第二子帧包括至少N个符号;
当所述第二子帧被映射到第二子载波间隔的频带上时,所述第二子帧包括至少2N个符号。
该实施方式中,可以实现为数据帧配置包括上述第二子帧,由于上述第二子帧的长度是上述第一子帧的长度的N倍,这样可以传输高容量高移动速度 的业务。例如:当第二子帧映射到子载波间隔为15kHz的频带上时,第二子帧包括N个符号,当第二子帧映射到子载波间隔为30kHz的频带上时,第二子帧包括2N个符号,当第二子帧映射到子载波间隔为60kHz的频带上时,第二子帧包括4N个符号。
本实施例中,上述至少两个子帧可以包括第三长度的第三子帧,其中,所述第三长度等于M×N倍所述第一长度,所述M和N为大于1的正整数;或者
上述至少两个子帧可以包括第四长度的第四子帧,其中,所述第四长度等于K×M×N倍所述第一长度,所述K、M和N均为大于1的正整数。
例如,如图6所示,其中,第一子帧的第一长度TL0=66.67us+5.2us=71.87us,第二子帧的第二长度TL1=N×TL0=0.5ms,第三子帧的第三长度TL2=M×TL1=1ms,第四子帧的第四长度TL3=K×TL2=2ms。当然,这里仅是以第一长度71.87us进行举例。
另外,本实施例中,每个所述子帧包括的符号数量与映射到的频带的子载波间隔成正比。即所述子载波间隔越大,所述子帧包括的符号数量越多;所述子载波间隔越小,所述子帧包括的符号数量越少。
由于每个子帧的长度固定,这样可以实现当子载波间隔越大,符号宽度越窄,可支持的移动速度越大;当子载波间隔越小,符号宽度越宽,可服务的用户距离越远,覆盖范围越大。同时,子帧越长,资源利用效率相对越高。因此,通过上述第一子帧、第二子帧、第三子帧和第四子帧和不同的子载波间隔对应,可适配不同的应用场景和业务需求。
例如:第一子帧可适用于低时延的业务类型,第二子帧配置的子载波间隔可适用于高容量高移动速度的业务,第三子帧适用于大包传输,第四子帧配置较小的子载波间隔(比如3.75kHz或7.5kHz)可适用于大连接场景下时延不敏感的小包业务。具体可以参考图7,如图7所示,第一子帧可以用于在超短TTI(Ultra-short TTI)的频带上传输时,或者在子载波间隔为15、30和60kHz的频带上传输时,第一子帧可以用于传输低时延(Low latency)的业务,或者传输critical MTC。第二子帧可以在正常传输(Normal Transmission)频带,或者 在子载波间隔为15、30和60kHz的频带上传输时,第二子帧可以用于传输高容量(High capacity)或者高移动速度(High mobility)的业务。第三子帧可以用于在长TTI(Long TTI)的频带上传输,或者在子载波间隔为15、30和60kHz的频带上传输时,第三子帧可以用于传输高容量(High capacity)的业务。第四子帧可以用于在超窄带宽(Ultra-Narrowband)的频带上传输,或者在子载波间隔为3.75和7.5kHz的频带上传输时,第四子帧可以用于传输小包(Small packet)和大连接(Massive connection)的业务。
本实施例中,步骤101可以包括:
发送机配置用于无线信号传输且映射在目标频带上的数据帧,其中,所述数据帧包括如下至少一项:
所述第一子帧、所述第二子帧、所述第三子帧和所述第四子帧;
所述目标频带的子载波间隔包括如下任意一项:
所述第一子载波间隔、所述第二子载波间隔、第三子载波间隔、第四子载波间隔和第五子载波间隔,其中,所述第三子载波间隔大于所述第二子载波间隔,所述第四子载波间隔大于所述第三子载波间隔,所述第五子载波间隔小于所述第一子载波间隔。
通过上述对第一子帧、第二子帧、第三子帧和第四子帧的描述可知,第一子帧、第二子帧、第三子帧和第四子帧的长度都为成倍数关系的,这样在配置数据帧可以使用第一子帧、第二子帧、第三子帧和第四子帧中的多个子帧进行拼装,以适用当前的业务和场景。
另外,通过上述目标频带的描述可知,拼装的数据帧可以是不同的子载波间隔的频带上传输,具体可以按照应用场景和业务需求进行拼装。例如:如图8所示,通过滤波器,大的系统带宽可以被分成若干个频带,或者理解为若干个子带(subband),每一个频带配置不同的子载波间隔,例如:频带1的子载波间隔为60kHz,频带2的子载波间隔为30kHz,频带3的子载波间隔为15kHz,频带4的子载波间隔为15kHz,频带5的子载波间隔为3.75kHz。这样在本实施例中,可以根据不同的应用场景,同一子帧类型可以配置在不同频带上,且配置在不同的频带上有不同的数据结构,例如:第一子帧、第二子帧、第三子 帧和第四子帧都可以配置在频带1至频带5中的任意频带上。另外,根据不同的业务需求,同一频带上也可以配置不同的子帧类型。例如:在频带1上可以配置包括第二子帧和第三子帧的数据帧,在频带2上可以配置包括第一子帧、第二子帧和第三子帧的数据帧,在频带3上可以配置包括第一子帧和第二子帧的数据帧,在频带4上可以配置包括第一子帧、第二子帧和第三子帧的数据帧,在频带5上可以包括第四子帧的数据帧。需要说明的是,这里描述的数据帧内包括的各子帧之间的位置关系可以是根据业务需求进行灵活调整,即在拼装数据帧时可以根据业务需求配置各子帧的位置。
该实施方式中,由于不同的子帧的长度之间具有倍数关系,因此可以根据场景和业务需求灵活拼装数据帧。
该实施方式中,上述数据帧包括的子帧可以按第一种组合方式组合,或者所述数据帧包括的子帧可以按第二种组合方式组合。
其中,所述第一种组合方式和第二种组合方式不同。这里的第一种组合方式可以是适用于目标频带上的任意组合方式,例如:第一种组合方式可以是预先指定的组合方式,或者第一种组合方式可以是根据当前应用的场景按照预先获取的第一组合规则确定的组合方式,或者第一种组合方式可以是根据当前传输的业务按照第一组合规则而确定的组合方式等。例如:针对图8所示的频带1,第一种组合方式可以如图8所示的在频带1上使用第二子帧和第三子帧进行组合;或者针对图8所示的频带1,第一种组合方式还可以是使用第一子帧和第二子帧进行组合等。而上述第二种组合方式可以是适用于目标频带上除上述第一种组合方式之外的任意组合方式。例如:第二种组合方式可以是预先指定的另一种组合方式,或者第二种组合方式可以是根据当前应用的场景按照预先获取的第二组合规则而确定的组合方式,或者第二种组合方式可以是根据当前传输的业务按照第二组合规则而确定的组合方式等。例如:针对图8所示的频带1,第一种组合方式还可以是使用第一子帧和第三子帧进行组合或者使用第一子帧、第二子帧和第三子帧进行组合等。
另外,上述实施方式中,上述数据帧包括的子帧的组合方式可以由控制信号动态指定或者可以由高层信令指定。
上述由控制信号动态指定可以理解为数据帧包括的子帧的组合方式可以通过控制信号动态告诉接收机,这样发送机就可以灵活地配置数据帧内的子帧组合方式。同理,上述由高层信令指定可以理解为数据帧包括的子帧的组合方式可以通过高层信令告诉接收机,这样发送机就可以灵活地配置数据帧内的子帧组合方式。从而可以实现灵活地对数据帧内的子帧进行组合,以更好地满足5G移动通信多样化的业务需求。
另外,上述实施方式中,上述数据帧包括的子帧的组合方式可以预先与接收机协商。
该实施方式中,在配置上述数据帧前发送机就可以与接收预先协商好数据帧内的子帧的组合方式。这样在传输过程就不需要使用控制信号或者高层信令通知接收机数据帧内的子帧的组合方式,从而可以实现在传输时无需传输额外的控制信号或者高层信令,以节约网络传输资源。
上述实施方式中,上述数据帧还可以用于传输如下至少一项:
广播信令(Broadcast)、公共控制信息(Common Ctr)和同步信号(Sync)。
其中,这里的广播信令、公共控制信息和同步信号可以用于通知上述数据帧内子帧的组合方式,当接收机接收到这些信息时,就通过这些信息获得了数据帧的配置方式。这样可以实现发送机可以灵活配置数据帧内子帧的组合方式,因为无论配置哪一种组合方式,只能将该组合方式告诉接收机,接收机就可以在该组合方式下识别出各子帧。例如:图8所示的频带3上包括信息帧,该信息帧就可用于传输广播信令、用于传输公共控制信息和用于传输同步信号中的至少一项。
本实施例中,如图9所示,上述方法还可以包括如下步骤:
102、发送机向接收机发送所述数据帧。
103、接收机接收上述发送机发送的所述数据帧。
由于接收机接收到上述数据帧可以包括至少两个子帧,且每个所述子帧的长度固定,上述数据帧可以映射到子载波间隔不同的至少两个频带上,且每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应,这样接收机接收的该数据帧就可以满足5G移动通信多样化的业务需求,以提高接收机5G移 动通信的业务水平。
本实施例中,步骤103可以包括:
接收机接收发送机在目标频带上发送的所述数据帧。
其中,接收机接收到的上述数据帧内子帧结构和组合方式可以是参考本实施例中对于发送机发送上述数据帧的描述,此处不作重复说明。
另外,由于接收机接收到的数据帧内的子帧的组合方式可以灵活组合,这样接收机接收到的数据帧就更加容易适合接收机当前所处的场景和当前使用的业务,以更好地满足5G业务的需求。
另外,本实施例中,当上述数据帧包括的子帧的组合方式由控制信号动态指定或者由高层信令指定时,上述接收机可以通过接收发送机发送的控制信号或者高层信令获取上述数据帧内的子帧的组合方式,从而可以识别灵活组合的各子帧。
当上述数据帧包括的子帧的组合方式是预先与所述发送机协商的时,那么,接收机在接收到上述数据帧时就可以按照预先协商好的组合方式识别出各子帧。
另外,当上述数据帧还可以用于传输如下至少一项:
广播信令、公共控制信息和同步信号。
那么接收机可以通过上述数据帧传输的广播信令、公共控制信息和同步信号中的至少一项获取上述数据帧内的子帧的组合方式。
需要说明的是,本实施例中,上述第一子帧、第二子帧、第三子帧和第四子帧可以是分别表示不同类型的子帧,而不限定表示一个单独的子帧。
本实施例中,为了满足5G系统多样化发散的业务需求,提出的一种可以灵活拼装数据帧结构的方法,定长的子帧可以在不同场景下满足低时延需求,各子帧长度之间具有天然的倍数关系,从而易于拼装成帧。另外,本实施例了TTI长度和子载波间隔之间固定的对应关系,各子帧内的符号数可根据配置频带的子载波间隔灵活可变,各帧内的子帧配置方式也可灵活拼装,因此可同时满足多种不同特殊业务需求。
本实施例中,上述发送机可以是任何具备配置数据帧功能的发送机,例如: 基站、接入点设备、网关设备、服务器或者终端等,其中,终端可以包括:手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile station,MS),终端(terminal),终端设备(Terminal Equipment)等等。而上述接收机可以是接收数据帧的设备,例如:终端。
本实施例中,配置用于无线信号传输的数据帧,所述数据帧包括至少两个子帧,每个所述子帧的长度固定,所述至少两个子帧可映射到子载波间隔不同的至少两个频带上,且每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应。由于上述数据帧可以映射到子载波间隔不同的至少两个频带上,且每个所述子帧包括的符号数量与映射到的频带的子载波间隔对应,这样该数据帧就可以满足5G移动通信多样化的业务需求,以提高5G移动通信的业务水平。
