具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,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。
本发明各实施例的技术方案,可以应用于正交频分复用(Orthogonal Frequency Division Multiplexing,简称OFDM)系统中,例如,WLAN系统,特别是WiFi等。本发明各实施例的方法还可以应用于单载波(Single Carrier,简称SC)系统中。当然,本发明实施例的方法还可应用其它类型的OFDM系统。本发明实施例在此不作限制。
相对应的,发送端设备和接收端设备可以是WLAN中用户站点(Station,简称STA),该用户站点也可以称为系统、用户单元、接入终端、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置或用户设备(User Equipment,简称UE)。该STA可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称SIP)电话、无线本地环路(Wireless Local Loop,简称WLL)站、个人数字助理(Personal Digital Assistant,简称PDA)、具有无线局域网(如Wi-Fi)通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备。
另外,发送端设备和接收端设备也可以是WLAN中接入点(Access Point,简称AP),接入点可用于与接入终端通过无线局域网进行通信,并将接入终端的数据传输至网络侧,或将来自网络侧的数据传输至接入终端。接收端设备可以是与发送端设备相对应的通信对端。
以下,为了便于理解和说明,作为示例而非限定,以将本发明的传输数据的方法和装置在Wi-Fi系统中的执行过程和动作进行说明。
图1是本发明实施例可应用的传输数据的场景示意图。如图1所示的场景系统可以是WLAN系统,图1的系统包括一个或者多个接入点AP101和一个或者多个站点STA102,图1以一个接入点和两个站点为例。接入点101和站点102之间可以通过各种标准进行无线通信。其中,接入点101和站点 102之间可以采用多用户多入多出技术(Multi-User Multiple-Input Multiple-Output,简称MU-MIMO)进行无线通信。
本发明各实施例均可适用于802.11ad系统及其后更先进的通信系统,如工作在60GHz频段的WLAN中。该802.11ad系统可适用于点对点近距离的无线高清音视频信号传输、无线接入、回传、点到多点的传输等场景。
实施例一
本发明实施例一提供一种数据传输方法。该实施例的方法可由发送端设备执行。该发送端设备可为站点或接入点。当发送端设备为接入点时,接收端设备为站点;当发送端设备为站点时,接收端设备为接入点。图2为本发明实施例一提供的数据传输方法的流程图。如图2所示的方法应用于60GHz频段的WLAN系统中,该方法可包括:
S201、对至少两个信道中每个信道对应的信息比特进行编码调制,获得该每个信道的调制符号。
该至少两个信道例如可以包括4个信道,每个信道的带宽为2.16GHz。该每个信道对应的信息比特可以为发送端设备的信号源产生的数字基带信号。该每个信道对应的信息比特可以为至少一个比特组成的比特流。该至少两个信道中不同信道对应的信息比特可以不同,即该不同信道对应的信息比特可以为不同比特组成的比特流。
对该每个信道对应的信息比特进行编码调制,例如可以是对该每个信道对应的信息比特的比特流进行加密、信道编码等处理生成编码符号,继而采用预设的调制方式对该编码符号进行调制,从而获得该每个信道的调制符号。该发送端设备可以通过该每个信道对应的编码调制模块对该每个信道对应的信息比特进行编码调制。该每个信道对应的编码调制模块,可以作为该发送端设备的一个单信道数据处理器集成该发送端设备内部。该每个信道对应的编码调制模块,对该至少两个信道中不同信道对应的信息比特进行编码调制采用的编码调试方式可以相同。
S202、对该至少两个信道的调制符号进行交织,确定至少一个射频通道中每个射频通道的数据符号。
该至少一个射频通道中一个射频通道可对应发送端设备的一个发射天线。也就是说,该发送端设备的射频通道的数量即为该发送端设备的发射天 线个数。
对该至少两个信道的调制符号进行交织可以是将至少两个信道的调制符号进行重排序,继而根据重排序后的符号确定该每个射频通道的数据符号,可使得该至少两个信道的调制符号分布至该至少两个射频通道。也就是说,该每个射频通道的数据符号可包括该至少两个信道的部分符号。
可选的,对该至少两个信道的调制符号进行交织,例如可以通过该发送端设备设备的多信道交织器将该至少两个信道的调制符号进行交织,从而对该至少两个信道的调制符号的进行重排序,形成该至少两个信道的调制符号组成的新的符号序列,从而将该至少两个信道汇聚成一个信道。该新的符号序列即为该汇聚成的一个信道的调制符号。其中,该多信道交织器例如可以通过软件和/或硬件的形式实现。
若发送端设备包括一个发射天线,即该至少一个射频通道包括一个射频通道,该发送端设备还根据该多信道交织器输出的该新的序号序列确定该一个射频通道的数据符号。若该发送端设备包括至少两个发射天线,即该至少一个射频通道包括至少两个射频通道,该发送端设备还需根据该多信道交织器输出的该新的符号序列确定该至少两个射频通道中每个射频通道的符号,继而分别根据该每个射频通道的符号确定该每个射频通道的数据符号。
S203、根据该每个射频通道的数据符号生成该每个射频通道的待发送数据。
不同的载波传输方式,该发送端设备发送的无线帧结构中,数据部分的数据结构不同,因此该发送端设备例如可以是根据不同的载波传输方式分别采用对应的方式确定该每个射频通道的待发送数据。
S204、在该每个射频通道上发送该每个射频通道的待发送数据。
若载波传输为单载波传输方式,则该发送端设备可以是在该每个射频通道的单载波上发送该每个射频通道的待发送数据。若载波传输为多载波传输方式,则该发送端设备可以是在该每个射频通道的多载波上发送该每个射频通道的待发送数据。
本发明实施例一提供的数据传输方法,可通过对至少两个信道的调制符号进行交织,确定至少一个射频通道中每个射频通道的数据符号,使得该至少两个信道的调制符号分布至该每个射频通道,因而将根据该每个射频通道 的数据符号生成的该每个射频通道的待发送数据进行发送,可使得该每个射频通道可传输该至少两个信道对应的数据,从而使得通信系统的容量不受该发送端设备的射频通道数量的限制,提高通信系统的容量。
实施例二
本发明实施例二还提供一种数据传输方法。图3为本发明实施例二提供的一种数据传输方法的流程图。如图3所示,该方法在上述实施例的基础上,可选的,上述S202中对该至少两个信道的调制符号进行交织,确定该每个射频通道的数据符号可以包括:
S301、对该至少两个信道的调制符号及采用行进列出的形式进行交织,获得第一符号矩阵。
S302、根据该第一符号矩阵及及所述至少一个射频通道的通道个数确定该每个射频通道的数据符号。
可选的,S301中对该至少两个信道的调制符号采用行进列出的形式进行交织,获得第一符号矩阵可包括:
根据公式(1),对该至少两个信道的调制符号采用行进列出的形式进行交织,获得该第一符号矩阵;
其中,该公式(1)可以为:
T(m,k)=xm(k)         公式(1)。
其中,m=1,2…,M;k=1,2…,K;M为该至少两个信道中信道的个数;K为单位符号周期内该每个信道的调制符号中的符号个数;T为该第一符号矩阵;xm(k)为第m个信道的调制符号中的第k个符号。
其中,该单位符号周期指的是一个正交频分复用(Orthogonal Frequency Division Multiplexing,简称OFDM)符号周期。T(m,k)为所述第一符号矩阵中第m行k列的参数。
举例来说,若M为2,即该至少两个信道中信道个数可以为2。不同载波传输方法,该发送端设备发送的无线帧结构中,数据部分的数据结构不同,单位符号周期内该每个信道的调制符号中的符号个数不同。也就是说,K可以是根据该发送端设备的载波传输所确定的。若该发送端设备采用的在载波传输方式为单载波传输方式,则对该每个信道对应的数据进行编码调制获得的单位周期内的该每个信道的调制符号中的符号个数可以为448,即K为 448。若该发送端设备采用的在载波传输方式为多单载波传输方式,则对该每个信道对应的数据进行编码调制获得的单位周期内的该每个信道的调制符号中的符号个数可以为336,即K为336。
该两个信道中第一信道的调制符号x1(k)可以为x1(1),x1(2),…,x1(K)。该两个信道中第二信道的调制符号x2(k)可以为x2(1),x2(2),…,x2(K)。
因此根据该两个信道的调制符号及该公式(1)可获得该第一符号矩阵T可以为
Figure PCTCN2015080204-appb-000046
上述S302中根据该第一符号矩阵及该至少一个射频通道的通道个数确定该每个射频通道的数据符号可以包括:
采用公式(2),根据该第一符号矩阵及该至少一个射频通道的通道个数确定该每个射频通道的数据符号;
其中,该公式(2)可以为:

若该发送端设备的包括2个射频通道,即该L为2。
根据该公式(2)及该第一符号矩阵,可确定该2个射频通道中第1个射频通道的数据符号y1(1),y1(2),…,y1(K)可依次为

本发明实施例二还提供另一种数据传输方法。图4为本发明实施例二提供的另一种数据传输方法的流程图。如图4所示,该方法在上述实施例的基础上,可选的,上述S202中对该至少两个信道的调制符号进行交织,确定该每个射频通道的数据符号可以包括:
S401、对该至少两个信道的调制符号及采用列进行出的形式进行交织,获得第二符号矩阵。
S402、根据该第二符号矩阵及及所述至少一个射频通道的通道个数确定该每个射频通道的数据符号。
可选的,S401中对该至少两个信道的调制符号及采用列进行出的形式进行交织,获得第二符号矩阵,可包括:
根据公式(3),对该至少两个信道的调制符号采用列进行出的形式进行交织,获得该第二符号矩阵。
其中,该公式(3)可以为:
T(k,m)=xm(k)      公式(3)
其中,m=1,2…,M;k=1,2…,K;M为该述至少两个信道中信道的个数;K为单位符号周期内该每个信道的调制符号中的符号个数;T为该第二符号矩阵;xm(k)为第m个信道的调制符号中的第k个符号。
其中,T(m,k)为所述第二符号矩阵中第k行m列的参数。
举例来说,若M为2,即该至少两个信道中信道个数可以为2。
该两个信道中第一信道的调制符号x1(k)可以为x1(1),x1(2),…,x1(K)。该两个信道中第二信道的调制符号x2(k)可以为x2(1),x2(2),…,x2(K)。
因此根据该两个信道的调制符号及该公式(3)可获得该第二符号矩阵T可以为

若该发送端设备的包括2个射频通道,即该L为2。
根据该公式(4)及该第二符号矩阵,可确定该2个射频通道中第1个射频通道的数据符号y1(1),y1(2),…,y1(K)可依次为

本发明实施例二的数据传输方法,通过多种对该至少两个信道的调制符号进行交织的实现方案,可更好地保证该每个射频通道的数据符号可包括该至少两个信道的部分调制符号,从而将该每个信道的调制符号分布在该至少一个射频通道对应的频带上,实现调试符号在频域的分集发送,提高系统的容量。
