Description

一种频分双工无线宽带通信方法、装置及基站 技术领域
本文涉及但不限于一种无线宽带通信技术领域，尤其涉及一种频分双工无线宽带通信方法、装置及基站。
背景技术
在无线宽带通信系统中，Massive MIMO(Massive Multiple-Input Multiple-Output，大规模多输入多输出系统)及其相关技术得到了广泛的研究，其中相关技术包括多天线发送预处理技术以及信道检测技术。在发送端获得信道状态信息的情况下，使用发送预处理可明显提升系统性能。
TD-LTE(Time Division Long Term Evolution，分时长期演进技术)的上下行传输使用同样的频率，当上下行的发送时间间隔足够短时，可认为上行信道与下行信道的衰落基本相同，即上下行信道具有互易性。基于这一特性，TD-LTE基站可以通过上行发送信号的检测(如上行的参考信号)来估计下行发送信号将要经历的信道衰落，并由此来确定下行传输的方案和参数，在保证下行信道衰落的估计精度的同时，可以节省终端的反馈开销。
但是，传统频分双工系统的上下行链路工作于不同频点，请参见图1，图1中将系统可用带宽划分成两部分，一部分用作设置上行信道(该上行信道相对基站为接收信道，相对终端则为发送信道)，另一部分用作设置下行信道(该下行信道相对基站为发送信道，相对终端则为接收信道)，导致上下行信道频率相差较大，相关性低，使得上下行信道的互易性较差。因此，移动台需要使用专门的反馈信道把测量到的下行信道的状态信息发送到基站，基站才可确定下行信道传输的方案和参数，从而消耗了系统资源，降低了信道检测的准确度，同时也增加了系统复杂度。

第二评估子模块，设置为当所述接收子频段中与所述发送信道对应位置的接收信道为两个或两个以上时，将这两个或两个以上接收信道的状态进行均值计算，得到所述发送信道的状态；或者，选择任意一个接收信道的状态作为所述发送信道的状态。
可选的，所述发送信道和接收信道均为同级网元之间的通信信道或者上下级网元之间的通信信道。
本发明实施例还提供了一种基站，包括如上所述的频分双工无线宽带通信装置。
本发明实施例还提出了一种计算机可读存储介质，存储有计算机可执行指令，计算机可执行指令用于执行上述描述的任意一个方法。
本发明实施例的有益效果是：
本发明实施例提供的频分双工无线宽带通信方法、装置及基站，将可用带宽划分成相互交错的发送子频段和接收子频段，然后在所述发送子频段和接收子频段中分别对应设置发送信道和接收信道，使得发送信道与接收信道 频率相近，导致两者信道状态相似、相关性强且互易性较好；因此，当对其中一发送子频段中的其中一发送信道进行状态估算时，根据与该发送子频段对应的接收子频段中，与该发送信道对应位置的接收信道的状态进行估算，并进行发送预处理，从而有效地避免了使用专门的反馈信道将发送信道的状态信息进行反馈才能确定发送信道的传输方案和参数。因此，本发明实施例提供的方案无需采用专门的反馈信道就可对信道的状态进行检测，从而提升了系统的信道估计实时性以及准确度，同时节省了系统空口资源，降低了系统复杂度。

请参考图2，图2为本实施例提供的频分双工无线宽带通信方法流程图。
在本实施例中，频分双工无线宽带通信方法包括：
S101，将可用带宽划分成相互交错的发送子频段和接收子频段，发送子频段和接收子频段中分别对应设置发送信道和接收信道；
S102，对其中一发送子频段中的其中一发送信道进行状态估算时，根据与该发送子频段对应的接收子频段中，与所述发送信道对应位置的接收信道的状态进行估算。
通过上述步骤，在对发送信道的状态进行估算时，将发送子频段与接收子频段相互交错，并在所述发送子频段和接收子频段中分别对应设置发送信道和接收信道，使得同一部通讯设备的发送信道与其对应位置的接收信道之间的频率差距小于传统频分双工中发射信道与接收信道的频率差距，增强了收、发信道的互易性，从而提升了系统的信道估计实时性，降低了系统复杂度，同时也节省了系统空口资源。
应当理解的是，上述步骤中，发送信道和接收信道相对于不同级的设备直接则为对应的上、下行信道。例如，相对于基站和终端之间，发送信道相对于基站来说则是指下行信道，接收信道相对于基站来说则是指上行信道；相应的，接收信道相对于终端来说则是指下行信道，发送信道相对于终端来说则是指上行信道。基站到终端属于下行信道，终端到基站属于上行信道。在一个基站对多个终端的通信系统中，不同终端所处的地理位置不同，导致同个频点的下行信道以及同个频点的上行信道在用于传输不同终端的信息时，信道状态是有区别的。讨论信道估计时，应该限制在可接受的一定时间范围内，讨论同一台终端的上下行信道的互易性。
应当理解的是，本实施例中的发送信道和接收信道也包含同一级设备之间的信道。例如，在一对一的对等通信系统中不存在上下行信道，收发信道对于双方而言，是一个相反的称呼。如从通信设备1到通信设备2的无线传输信道，是通信设备1的发送信道，同时也是通信设备2的接收信道。所以，上述设备不限定于终端和基站，对于其他设备若满足收、发信道的关系同样属于本实施例保护的范围。
对于S101步骤，同级网元或者不同级网元之间会事先协商出一套可用带宽划分规则，根据划分规则将可用带宽进行划分，然后根据该划分结果，对信道进行估计。
可选的，在S101步骤中的相互交错，本实施例中相互交错是指将可用带宽划分成至少一个发送子频段和至少两个接收子频段，或者划分成至少两个发送子频段和至少一个接收子频段，并且发送子频段与接收子频段全部交错分布。发送子频段和接收子频段中都包括至少一个信道，发送子频段中包括发送信道，接收子频段中包括接收信道，其中，发送信道的频域宽度与接 收信道的频域宽度不做限定，二者可相同也可不相同，发送子频段中的发送信道数量与所述接收子频段中的接收信道数量可以相等，也可以不相等。可选的方案是，发送子频段和接收子频段中均仅设置一个信道，则发送信道与接收信道密集的相邻交错，频率较接近，使得对应发送信道和接收信道之间的互易性也更好，因此信道估计的实时性也较好。但应当理解的是，本实施例在对应的发送子频段和接收子频段中设置信道的个数还可根据具体需求等因素设置多个，例如图3所示的设置方式，则是在对应的发送子频段中设置两个发送信道，在对应的接收子频段中设置两个接收信道(图3中箭头向上的表示发送信道，反之表示接收信道)。
此外，发送子频段中的发送信道与接收子频段中的接收信道对应设置，并且发送子频段中发送信道的数量等于接收子频段中接收信道的数量，对于发送信道与接收信道的对应关系，存在以下两种情况：
一种情况是，发送信道的中心频点与对应位置的接收信道的中心频点之间的间隔为固定值，也就是说每对收、发信道的中心频点间隔都相等，只要该固定值小于相关技术中发送信道与接收信道的最小中心频点间隔即可。
另一种情况是，发送信道与接收信道之间的中心频点间隔可不等同，只要其最大中心频点间隔小于相关技术中最小中心频点间隔即可，本发明实施例中的中心频点间隔的大小可参照相关技术中中心频点的数量值进行配置。
对于上述中心频点间隔，由于本发明可应用于LTE(Long Term Evolution，长期演进技术)系统中，在LTE系统中下行采用OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用技术)作为其无线网络演进的标准之一，OFDM技术可将频谱上几段分散的可用带宽中的信道聚合形成系统资源总带宽，以达到节约带宽资源的目的，因此，本实施例信道之间可能会部分重叠，且信道重叠的方式是相关技术中任意规则的重叠，以及在LTE系统中聚合场景或其他场景都采用现有方式。对于同一台基站下不同终端而言，基站分配的上下行信道之间的中心频点间隔也会相应的不同。基站在信道分配时，对于同一台终端而言，相邻信道的中心频点间隔可根据实际需要进行相应调整，这里不做限定，可选地若干倍15千赫兹(KHZ)内的对应信道分配给同一台终端，以便于同台终端上下行频点更接近，拥有更好的互易性，更有 利于信道评估。
可选的，对于S102步骤，对其中一个发送子频段中的某一个发送信道进行状态估算时，首先会将与该发送信道对应位置的接收信道的状态记录在一个信道状态表中，也可以是其他载体，这里不做限定。应当理解的是，信道状态表中包括多个发送信道或者接收信道的状态，且信道状态表有多个；然后当需要对该发送信道的状态进行估算时，只需要从信道状态表中查找对应位置的接收信道的状态就可得到该发送信道的状态。应当注意的是，信道状态表中发送信道与接收信道的对应关系是明确的。例如，在基站与终端之间，一般而言，一个终端会占用多个发送信道和多个接收信道。基站对于一个终端的资源分配，至少分配一个发送信道和一个与发送信道对应的接收信道，可选地多个发送信道与接收信道进行交错。同时，基站对下属的每一个终端都建立一张信道状态表，例如，在信道状态表更新周期内，每当基站接收到终端的上行信号时，就会将对应的上行信道的状态数据记录在该终端对应的信道状态表上，以便对对应位置的下行信道的状态进行估算。
在收发信道交错的基础上，对发送信道的状态进行估算时，会根据与发送信道对应位置的接收信道的状态进行估算，信道估算存在以下两种情况：
若当前发送信道只有一个对应位置的接收信道，则直接将该接收信道的状态作为当前发送信道的状态；
若当前发送信道有两个或两个以上对应位置的接收信道，则对两个或两个以上接收信道的状态进行均值计算，估算出当前发送信道的状态，或者选择任意一个接收信道的状态作为当前发送信道的状态。
在无线通信领域，信道状态信息(CSI，Channel State Information)，就是通信链路的信道属性。它描述了信号在每条传输路径上的衰弱因子，即信道增益矩阵H中每个元素的值，如信号散射(Scattering)、环境衰弱(fading，multipath fading or shadowing fading)、距离衰减(power decay of distance)等信息。对两个传输路径上对应的衰弱因子数值进行均值计算，得出新的信道增益矩阵。
因此，对两个或两个以上接收信道的状态进行均值计算，估算出当前发 送信道的状态包括：
对两个或两个以上接收信道的信道增益矩阵进行均值计算，得到发送信道的信道增益矩阵。
例如，请参见图4所示的划分示例，对于子频段中只包括一个信道的情况，可将每一个信道按频率顺序依次编号，接收信道使用编号为偶数的子载波，发送信道使用编号为奇数的子载波。当对编号为3的发送信道的状态进行估算时，该信道有两个相邻的接收信道(分别为编号为2和4的信道)，则将编号为2和4的信道的状态的均值作为编号为3的信道的状态；或者根据预定的选择规则从编号为2和4的信道的状态中选择一个作为编号为3的信道的状态。类似的，当对编号为1的信道的状态进行估算时，只需将编号为2的信道的状态作为该信道的状态。
可选的，由于系统对数据实时性的要求较高，当信道状态表中记录的状态信息超过一定的时间，则需要将对应的状态信息清除，避免接收信道状态变化后对发送信道的状态判断不准确。
可选的，对信道进行估算时，可选地以一个资源块的频域宽度为基本单元。一个资源块频域中包括12个信道，即一个资源块的频域宽度为15KHZ×12＝180KHZ。另外，本实施例中均是以一段连续的可用带宽为单元，进行收发信道交错处理，对于其他段可用带宽，也同样采用本实施例中的方式对带宽进行划分，对信道进行估算。本实施例除了可以应用在LTE系统，也可以应用在5G或其他制式的通讯系统上。在其他系统中，只要应用到本实施提出的方案，也同样属于本发明保护的范围。

应当理解的是，本实施例中的发送信道和接收信道也包含同一级设备而之间的信道。例如，在一对一的对等通信系统中不存在上下行信道，收发信道对于双方而言，是一个相反的称呼。如从通信设备1到通信设备2的无线传输信道，是通信设备1的发送信道，同时也是通信设备2的接收信道。所以，上述设备不限定于终端和基站，对于其他设备若满足收、发信道的关系同样属于本实施例保护的范围。

此外，发送子频段中的发送信道与接收子频段中的接收信道对应设置，并且发送子频段中发送信道的数量等于接收子频段中接收信道的数量，对于发送信道与接收信道的对应关系，存在以下两种情况：
一种情况是，发送信道的中心频点与对应位置的接收信道的中心频点之间的间隔为固定值，也就是说每对收、发信道的中心频点间隔都相等，只要该固定值小于相关技术中发送信道与接收信道的最小中心频点间隔即可
另一种情况是，发送信道与接收信道之间的中心频点间隔可不等同，只要其最大中心频点间隔小于相关技术中最小中心频点间隔即可，本发明实施例中的中心频点间隔的大小可参照相关技术中中心频点的数量值进行配置。
