Definitions

  • Time division multiple access is affected by transmission delay and signal multipath propagation. To ensure that users are orthogonal to each other, the protection time needs to be added to the system design. Similarly, due to the non-ideality of the filter, the edge of the signal bandwidth is unlikely to drop, and the out-of-band spread of the signal is inevitable. To ensure orthogonality, the guard bandwidth needs to be added in the frequency division multiple access system. Due to the influence of multipath, code division multiple access cannot be guaranteed to be completely orthogonal between code words, which also brings loss of capacity. The orthogonal frequency division multiplexing multiple access sub-channels have a certain bandwidth overlap, which improves the frequency band utilization.

本申请主张在2014年7月2日在中国提交的中国专利申请号No.201410312309.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开文本涉及无线通信技术领域，特别涉及一种数据传输的方法、系统和设备。
背景技术
移动通信需要使所有的用户共享有限的无线资源，以实现不同用户不同地点同时通信并尽可能减少干扰的目的，这就是多址接入技术。
随着无线通信的快速发展，用户数和业务量呈爆炸式增长，这对无线网络的系统容量不断提出更高的要求。业界研究预测，每年移动数据业务流量以翻倍的速度增长，到2020年全球将有大约500亿用户设备接入无线移动网络。爆炸性的用户增长使得多址接入技术成为网络升级的核心问题。多址接入技术决定了网络的基本容量，并且对系统复杂度和部署成本有极大地影响。
传统的移动通信(1G-4G)采用正交多址接入技术，如频分多址，时分多址，码分多址，正交频分复用多址等。
时分多址因为传输时延及信号多径传播的影响，为保证用户相互正交，系统设计时需要加入保护时间。同样的，由于滤波器的非理想性，信号带宽边缘不可能突降，信号的带外扩散也不可避免，为保证正交性，在频分多址系统中就需要加入保护带宽。码分多址由于多径的影响，码字之间无法保证完全正交，同样带来了容量的损失。正交频分复用多址各子信道有一定的带宽重叠，提高了频带利用率，但在时域上为保证符号正交，也引入了循环前缀，同样牺牲了系统效率。为了使系统发送和接收简单，传统的移动通信系统采用正交多址技术和线性接收机作为基础来设计。
综上所述，目前从多用户信息理论的角度来看，正交方式只能达到多用 户容量界的内界，造成无线资源利用率比较低。

具体实施方式
下面结合附图和实施例，对本公开文本的具体实施方式做进一步描述。以下实施例仅用于说明本公开文本，但不用来限制本公开文本的范围。
为使本公开文本实施例的目的、技术方案和优点更加清楚，下面将结合本公开文本实施例的附图，对本公开文本实施例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公开文本的一部分实施例，而不是全部的实施例。基于所描述的本公开文本的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开文本保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开文本所属领域内具有一般技能的人士所理解的通常意义。本公开文本专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
以下结合附图对本公开文本的原理和特征进行描述，所举实例只用于解释本公开文本，并非用于限定本公开文本的范围。
本公开文本实施例发送端对一个或多个用户设备的信号进行发送处理；对发送处理后的一个或多个用户设备的信号进行非正交特征图样映射，以使不同用户设备的信号在对应的无线资源叠加，并根据非正交特征图样映射的结果，发送处理后的一个或多个用户设备的信号。由于能够使一个或多个用户设备的信号在无线资源进行非正交的叠加，实现了非正交多址接入传输，从而提高了无线资源利用率。
这里，如上提及的非正交特征图样是指在相同的时域和频域资源上对具有一定特征的信号图样进行叠加，使得这些信号在相同时域和频域资源上不能够以正交的方式被分割。另一方面，如上提及的非正交特征图样映射是指在相同时域和频域资源上进行多用户传输时，对多个用户的信号按照非正交 特征图样叠加的方式来进行信号叠加传输，而每个用户的信号对应非正交特征图样中的一种信号图样。
在实施中，本公开文本实施例可以对现有正交多址接入的资源进行进一步多用户复用，从而实现非正交多址接入传输；也可以直接对多用户复用，从而实现非正交多址接入传输。
在实施中，若是上行传输，则发送端是用户设备，接收端是网络侧设备；
若是下行传输，则发送端是网络侧设备，接收端是用户设备。
本公开文本实施例的网络侧设备可以是基站(比如宏基站、微基站、家庭基站等)，也可以是RN(中继)设备，还可以是已知或未知的其它网络侧设备。
下面结合说明书附图对本公开文本实施例作进一步详细描述。
如图1所示，本公开文本实施例一进行数据传输的系统包括：发送设备10和接收设备20。
发送设备10，用于对一个或多个用户设备的信号进行发送处理；对处理后的一个或多个用户设备的信号进行非正交特征图样映射，以使不同用户设备的信号在对应的无线资源叠加；根据非正交特征图样映射的结果，发送处理后的一个或多个用户设备的信号。
接收设备20，用于对收到的对应于多个用户设备的信号进行非正交特征图样检测，确定接收的信号对应的非正交特征图样；利用检测到的非正交特征图样，对收到的接收的信号进行串行干扰抵消(Serial Interference Cancellation，SIC)方式的多用户设备检测，并进行接收处理，确定不同用户设备的数据。
可选地，所述发送设备对处理后的一个或多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备采用单独信号域非正交特征图样或联合信号域非正交特征图样，对处理后的一个或多个用户设备的信号进行非正交特征图样映射。
相应的，所述接收设备采用单独信号域非正交特征图样或联合信号域非正交特征图样，对接收的信号进行非正交特征图样检测。
可选地，所述信号域包括但不限于下列中的部分或全部：
功率域、空域和编码域。
在实施中，若是上行传输，则发送设备是用户设备，接收设备是网络侧设备。
若是下行传输，则发送设备是网络侧设备，接收设备是用户设备。
下面分别进行介绍。
情况一、下行传输，则发送设备是网络侧设备，接收设备是用户设备。
方式一、非正交特征图样为功率域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据功率域非正交特征图样，为多个用户设备的信号分配发射功率，其中为所有用户设备分配的发射功率之和等于系统可用总功率，以区分不同的用户设备。
相应的，所述接收设备若采用功率域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源，且每个用户设备具有不同的发射功率，则确定接收的信号中包含的非正交特征图样为功率域非正交特征图样。
如果没有特别说明，本公开文本实施例中的所有用户设备处于同一区域，比如同一个小区。
在实施中，为多个用户设备的信号分配发射功率，其中为所有用户设备分配的发射功率之和等于系统可用总功率。也就是说，同一时频资源上重叠的多个用户设备信号的发射功率，按特定约束条件在该时频资源的最大可用发射功率上进行分配。
例如，在基站发送两个用户设备的信号的情况下，假如可发送的总功率为P，则设置一个功率分配因子α(0＜α＜1)，为用户设备1分配功率αP，为用户设备2分配功率(1-α)P。
方式二、所述非正交特征图样为空域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据空域非正交特征图样，为至少一个用户设备的信号分配至少两个发射天线端口，且至少一个发射天线端口对应至少两个用户设备的信号，以区分不同的用户设备或同一用户设备的不同数据流。也就是说信号在对应的发射天线上发送，比如某信号对应两根天线，则该信号就会分别在这两根天线上发送。
相应的，所述接收设备若采用空域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源，且至少一个用户设备的信号对应至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，则确定接收的信号中包含的非正交特征图样为空域非正交特征图样。
在实施中，为至少一个用户设备的信号分配至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，其中每个天线端口是一个可识别的基带逻辑单元。每个基带逻辑单元可以对应一根物理天线，也可以对应多根物理天线的组合。
例如，在基站采用两根天线发送两个用户设备的信号的情况下，如果是正交发送方式，则只能为每个用户传输一个数据流总计两个数据流，不失一般性，假设用户1的数据流记为S1，在第一根天线发送，用户2的数据流记为S2，在第二根天线发送。在空域非正交发送方式下，基站可以发送大于两个数据流，不失一般性，假设基站可以为用户2多发送一个数据流S3。如果采用无空间编码的空域非正交发送方式，则用户1的数据流S1在天线1发送，用户2的数据流S2在天线1发送，用户2的数据流S3在天线2发送，即天线1上对应用户1的数据流S1和用户2的数据流S2，天线2上对应用户2的数据流S3。如果采用带空间编码的空域非正交发送方式，则用户1的数据流S1同时在天线1和天线2发送，用户2的数据流S2在天线1发送，用户2的数据流S3在天线2发送，即天线1对应用户1的数据流S1和用户2的数据流S2，天线2对应用户1的数据流S1和用户2的数据流S3。和无空间编码的空域非正交发送方式相比，带空间编码的空域非正交发送方式因为具有更多的发送信息，其对应的接收端的检测性能更高。方式三、所述非正交特征图样为编码域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据编码域非正交特征图样，为每个用户设备的信号分配不同的编码方式和不同的发送时延差，以区分不同的用户设备。
相应的，所述接收设备若采用编码域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源、不同的编码方式和不同的发送时延差，则确定接收的信号中包含的非正交特征图样为编码域非正交特征图样。
例如，在基站发送3个用户设备的信号的情况下，假如用户设备1的编码后的数据流在某时刻发送，则用户设备2的编码后的数据流相对于用户设备1延时t1后发送，用户设备3的编码后的数据流相对于用户设备2延时t2后发送。
方式四、所述非正交特征图样为功率域和空域联合信号域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据功率域和空域联合信号域非正交特征图样，为多个用户设备的信号分配发射功率。其中为所有用户设备分配的发射功率之和等于系统可用总功率，以及为至少一个用户设备的信号分配至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，以区分不同的用户设备。
相应的，所述接收设备若采用功率域和空域联合信号域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源，不同用户设备具有不同的发射功率，且至少一个用户设备的信号对应至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，则确定接收的信号中包含的非正交特征图样为功率和空域联合信号域非正交特征图样。
方式五、所述非正交特征图样为功率域和编码域联合信号域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据功率域和编码域联合信号域非正交特征图样，为多个用户设备的信号分配发射功率。其中为所有用户设备分配的发射功率之和等于系统可用总功率，以及为每个用户设备的信号分配不同的编码方式和不同的发送时延差，以区分不同的用户设备。
相应的，所述接收设备若采用功率域和编码域联合信号域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源、不同的发射功率、不同的编码方式和不同的发送时延差，则确定接收的信号中包含的非正交特征图样为功率域和编码域联合信号域非正交特征图样。
方式六、所述非正交特征图样为空域和编码域联合信号域非正交特征图样。
所述发送设备对处理后的多个用户设备的信号进行非正交特征图样映射，包括：
所述发送设备为多个用户设备的信号分配相同的发送时间和频率资源，并根据空域和编码域联合信号域非正交特征图样，为至少一个用户设备的信号分配至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，以及为每个用户设备的信号分配不同的编码方式和不同的发送时延差，以区分不同的用户设备。
相应的，所述接收设备若采用空域和编码域联合信号域非正交特征图样，确定接收到多个用户设备的信号对应相同的发送时间和频率资源、不同的编码方式和不同的发送时延差，且至少一个用户设备的信号对应至少两个发射天线端口、至少一个发射天线端口对应至少两个用户设备的信号，则确定接收的信号中包含的非正交特征图样为空域和编码域联合信号域非正交特征图样。

对于接收设备在进行串行干扰抵消方式的多用户检测时，是逐级分离出多个用户设备的检测信号并及时地消除同信道干扰，从而做到对多用户设备的高精度检测。
本公开文本实施例通过发送端和接收端的联合处理，在发送端采用多个信号域的非正交特征图样来区分用户，在接收端基于用户图样的特征结构，采用串行干扰抵消方式来实现多用户检测，从而做到多用户在已有时频无线资源的进一步复用。基于这种数据传输的方法、系统和设备对应的技术，被称为图样分割非正交多址接入技术，或简称图分多址(Pattern Division Multiple Access，PDMA)技术。
本公开文本实施例的图分多址技术能够同时适用于通信系统的上下行链路。以基站为例，如图2所示，本公开文本实施例图分多址框架示意图中，基站包含发送端和接收端。基站在发送时，通过发送端来完成下行链路通信信号的调制和发送。基站在接收时，通过接收端来完成上行链路通信信号的接收和检测。与传统的FDMA/TDMA/CDMA/OFDMA通过正交信号域(时域、频域、码域)区别多用户信息不同，PDMA在发送端利用信号在功率域、空域、编码域的单独或者联合非正交信号特征图样对多个用户信号进行区分，并在接收端利用串行干扰抵消检测接收方法对多用户信号进行有效检测，实现多用户在时频域上非正交传输，提升传输的频谱效率。
为简化说明，假设基站是多天线发送，用户设备是单天线接收，图3A给出了图分多址系统的下行链路示意图。
图3A中，发送端：对多用户设备的信号进行发送处理(比如编码、调制等过程)后，再进行非正交特征图样映射，完成发送端的多用户设备的信号在时频域的非正交叠加。
图3A中，接收端：以某个用户设备为例，对收到的用户设备的时频域叠加信号先进行非正交特征图样检测，对信号进行初步识别，然后对初步识别的信号采用串行干扰抵消的方式来进行该有效用户设备的检测。
在用户设备多天线接收的情况下，上述过程与单天线接收类似，只是接收端的前端由单天线接收变成多天线接收。
为简化说明，假设用户设备单天线发送，基站多天线接收，图3B给出了图分多址系统的上行链路示意图。
图3B中，发送端：在N个用户设备的情况下，每个用户设备分别对各自的信号进行编码、调制等过程后，再进行非正交特征图样映射，完成多个用户的发送信号在相同时频域的非正交叠加。
图3B中，接收端：基站对所接收到的多用户时频域叠加信号先进行非正交特征图样检测，对信号进行初步识别，然后对初步识别的多用户信号采用串行干扰抵消的方式来进行各用户设备的检测。
在用户设备多天线发送的情况下，上述过程与单天线发送类似，只是发送端的后端由单天线发送变成多天线发送。
对于非正交特征图样映射，它可以是某个信号域的单独非正交特征图样，也可以是多个信号域的联合非正交特征图样，例如功率域非正交特征图样映射，空域非正交特征图样映射，编码域非正交特征图样映射，功率域和空域联合非正交特征图样映射，功率域和编码域联合非正交特征图样映射，空域和编码域联合非正交特征图样映射，功率域和空域和编码域联合非正交特征图样映射，等等。
功率域图样分割技术根据用户设备信道质量进行功率分配，理论上每个用户设备都可占用系统所有时频资源，在发送端辅助用户调度算法，在接收端进行串行干扰抵消方式，在系统和容量、每用户容量、尤其是小区边缘用户容量上都得到了提升。图5A和图5B给出了一个示例，来说明功率域非正交特征图样映射在上下行链路的具体过程。它包括时频资源分配和功率分配两个基本过程。这两个过程的顺序可以调换，不用按照图中的顺序。
以功率域非正交特征图样为例，图4A给出了非正交相对于正交对无线资源占用的差别。在正交方式下，不同用户设备使用不同的频率资源。但在非正交方式下，不同用户设备使用相同的频率资源，不同的功率，以此来区分用户设备。功率域非正交特征图样是各用户时频资源块所对应的功率矢量。
空域图样分割技术基于串行干扰抵消方式，对用户设备的信号进行空间编码，实现用户设备的信号在串行干扰抵消检测后可以有效分割，从而实现多址接入。图6A和图6B给出了一个示例，来说明空域非正交特征图样映射 在上下行链路的具体过程。它包括时频资源分配和空间编码两个基本过程。这两个过程的顺序可以调换，不用按照图中的顺序。
以空域非正交特征图样为例，图4B给出了无空间编码和有空间编码两种非正交方式对无线资源占用的差别。在无空间编码方式下，用户1的信号只在天线1上发送，用户2的信号在天线1和天线2上发送，导致仅仅使用天线1来同时检测用户1和用户2的信号很困难。。但在有空间编码非正交方式下，用户1的信号在天线1和天线2上重复发送，实现每根天线上都有多用户信号的叠加，使得接收端能够充分利用多根天线的接收信息来进行多用户的检测，性能更为准确，这种空域非正交特征图样是各用户在不同天线阵元的空间编码矩阵。
编码域图样分割技术对多用户数据流进行先编码再延迟的多码流叠加，通过在多用户的数据间建立类似信道编码结构联系来实现，并基于信道编码理论进行结构优化设计。图7A和图7B给出了一个示例，来说明编码域非正交特征图样映射在上下行链路的具体过程。它包括复制、交织、延时这三个基本过程，其中复制和交织就是数据编码的过程，数据编码和延时这两个过程的顺序可以调换，不用按照图中的顺序。
以编码域非正交特征图样为例，图4C给出了非正交相对于正交对无线资源占用的差别。在正交方式下，不同用户设备使用不同的频率资源；但在非正交方式下，不同的用户设备使用相同的频率资源，不同的编码方式和不同的发送时延差，以此来区分用户设备。编码域非正交特征图样是各用户的编码序列和对应的发送时延差。
图8A和图8B给出了功率域和空域联合非正交特征图样映射在上下行链路的具体过程。图9A和图9B给出了功率域和编码域联合非正交特征图样映射在上下行链路的具体过程。其他多域联合非正交特征图样映射能够易于推出，这里不再赘述。图中各个过程的顺序可以调换，不用按照图中的顺序。
以功率域和空域联合信号域非正交特征图样为例，图4D给出了多个用户设备的信号在功率域和空域的叠加情况，不同的用户设备可以使用相同的时频资源，但是在功率和空间编码上有所区分。功率域和空域联合信号域非正交特征图样为功率非正交特征图样和空间编码非正交特征图样的组合。
从图4D可以清楚看出，使用非正交能够使得每个数据块传输十(10)个符号，而使用正交方式每个数据块只能传输九(9)个符号。也就是说，本公开文本实施例相比正交会有更高的频谱效率和更高的分集度(低差错)。
其他非正交特征图样与上述类似，不再重复介绍。
本公开文本实施例主要以功率域、空域、编码域这三类信号域对图分多址技术进行了举例说明，实际使用中，用户的非正交特征图样可进一步拓展到其他的潜在信号域。尤其，发送端的非正交特征图样设计方式，易于在接收端采用串行干扰抵消的检测方式，使得系统具有高性能低复杂度可实现。一方面，发送端的图样映射能够实现用户信息的有效分割，用户图样在接收端可以明确区分；另一方面，接收端可以针对所选取的发送端用户图样进行有效的串行干扰删除，从而恢复多用户的发送信息。这两个方面相辅相成，缺一不可。
根据本公开文本实施例，既能够适用于以码分多址为区分的第3代移动通信系统，也能够适用于以正交频分复用为区分的第4代移动通信系统，可以是现有移动通信系统的叠加技术，来进一步提升系统的容量和频谱效率。此外，本公开文本实施例的技术，还能够适用于未来的第5代移动通信系统(5G)，将满足其大容量需求。
通过单个信号域或多个信号域特征图样的自适应选择，本公开文本的图分多址技术，能够灵活适配5G系统的应用场景多样性。例如，通过功率非正交图样的自适应优化分配，图分多址技术能够有效克服用户远近效应，改善小区边缘覆盖性能；在宏蜂窝与微蜂窝叠加的异构网络场景中，通过功率非正交图样与多用户编码非正交图样的联合优化，图分多址技术能够动态适配网络结构的变化，增加多用户信号传输的灵活性；在分布式多天线或密集小区等典型场景中，通过将空域非正交图样与多用户编码非正交图样的联合优化，甚至进行更多信号域特征图样的联合优化，图分多址技术能够有效抑制多种来源的同频干扰，实现低能耗、高频谱效率的信号传输；在低功耗大连接物联网应用场景下，图分多址技术能够成倍增加上行接入用户数；在低时延高可靠物联网应用场景下，通过图分多址接入技术来进行冗余传输，能够提高传输资源的可靠性。
综上所述，图分多址技术中的用户特征图样，是针对用户属性，在多个信号域空间(功率域、空域、编码域等)中的非正交划分，无需依赖于时频无线资源的正交分割，因而可以放松无线资源数量的严格限制，既具有大幅度提高系统容量的潜力，又具有动态场景的高度适配性。
