Description

宽带集群系统组呼业务中用户的上行反馈方法及装置 技术领域
本发明涉及宽带无线通信领域，更具体的，涉及一种宽带集群系统组呼业务中用户的上行反馈方法及装置。
背景技术
组呼(Group Call)是LTE集群通信(Trunking Communications)中最常用的一种通信业务。进行组呼业务时组内所有用户共享下行集群专用信道，即所有用户均使用相同下行资源，只有主呼用户处于RRC连接态，其余用户基本处于RRC空闲态，公网标准中对于RRC连接态的终端会通过PUCCH信道或PUSCH信道复用进行下行接收数据状态的上行反馈，但对于RRC空闲态的终端不进行上行反馈。CCSA标准对于组呼业务也定义为不进行上行反馈。
因此组呼业务常采用保守调度的模式，但是这样会导致系统资源的大量浪费，且当某些组内用户信道恶化，系统不能实时调整，降低了系统的稳定性。

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做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。
实施例一
请参阅图1，在群组业务中，用户终端由于信号环境变化，例如图1中所示的建筑遮挡，会导致建筑物后的用户终端(UE)出现接收数据错误的情况，现有技术中，用户终端不能进行上行反馈，向无线终端反馈接收数据错误，造成用户信道恶化，降低了系统的稳定性。
针对上述问题，本实施例公开了一种宽带集群系统组呼业务中用户的上行反馈方法，应用于无线基站，请参阅图2，所述方法具体包括以下步骤：
S101：建立多个群组，并为每个所述群组分配对应的反馈信道，使当每个所述群组中的用户终端接收到的下行数据错误时通过相应的反馈信道进行反馈；
可以理解的是，无线基站发一份下行数据，群组内的多个用户终端同时接收，由于每个用户终端所处的位置不同，可能导致有的用户终端接收到的数据错误，另一些用户终端接收到的数据正常。
在群组建立时，无线基站会为每个群组分配对应的反馈信道，本实施例公开了两种分配反馈信道的模式。
分配模式一：
为每个所述群组分配一个公共的反馈信道，也就是说，每一个群组对应一个反馈信道，群组内的所有用户终端通过同一个反馈信道向无线基站反馈数据错误的反馈信号。
在这种模式下，无线基站只能通过反馈信号区分用户终端来自哪个群组，但相应的，这种模式可以有效的节约资源。
分配模式二：
确定每个所述群组中各个用户终端的优先级，所述优先级包括第一优先级和第二优先级；分别为每个第一优先级用户终端分配一个反馈信道；分别对每个所述群组中的第二优先级用户终端进行分组，并为每个组的第二优先级用户终端分配一个公共的反馈信道。
可以理解的是，第一优先级高于第二优先级，也就是说，第一优先级用户终端为重要用户终端，无线基站为其分配专用的反馈信道，第二优先级用户终端为普通用户终端，无线基站对每个群组中的第二优先级用户终端进行分组，每个组中第二优先级用户终端的数量可以根据实际情况，由无线基站进行调整，为每个组的第二优先级用户终端分配一个公共的反馈信道，组内的所有第二优先级用户终端通过同一个反馈信道向无线基站反馈数据错误的反馈信号。
在这种模式下，无线基站能通过反馈信号区分用户终端的优先级，也就是说，无线基站可以区分反馈的用户终端是否为重要客户，并可以在确定反馈的用户终端为普通客户时，区分反馈的用户终端来自哪个群组中具体的哪个组，这种模式无线基站对反馈的用户终端的识别精度高，重要用户终端可以通过专用反馈信道进行反馈，调高了反馈的可靠性。
S102：实时对各个所述群组的反馈信道进行盲检测；
具体的，S102的执行过程如下：
实时检测是否接收到来自各个所述群组的反馈信道上的反馈信号；
当接收到的反馈信号的功率超过功率门限值或信噪比超过信噪比门限值时，判定所述反馈信号为用户终端发送的数据错误反馈信号。
需要说明的是，无线基站并不知道用户终端发送了反馈信号，由于是码分资源反馈，也不能确定是哪些码道上进行了反馈，所以需要通过盲检测来确定用户终端是否发送了反馈信号。
S103：当检测到用户终端的数据错误反馈信号时，根据预设的反馈处理模式对所述用户终端所在的群组进行反馈处理。
具体的，对应于上述S101中两种分配反馈信道的模式，本实施例也公开了两种反馈处理模式。
需要说明的是，用户终端的反馈信号中包括带循环移位值的正交序列，不同反馈信道中传输的反馈信号中的正交序列是相同的，但是循环移位值不同，这样可以根据循环移位值区分反馈信道。
反馈信道的设计如图3所示，预设数量的反馈信道共同占用1RB时频域资源，所述时频域资源包括两个Slot，各个用户终端在Slot上传输码分反馈信号。
可以理解的是，1RB时频域资源中允许的反馈信道的数量是有限的，预设数量为1RB时频域资源中允许的反馈信道数量的上限。
本实施例提供的宽带集群系统组呼业务中用户的上行反馈方法，无线基站建立多个群组，并为每个群组分配对应的反馈信道，预设数量的反馈信道共同占用1RB时频域资源，提高了系统资源的利用率。
反馈处理模式一：
基于上述分配模式一，在本模式下根据用户终端的数据错误反馈信号中的循环移位值，确定所述用户终端所在的群组；降低向所述用户终端所在的群组发送数据的码率。
反馈模式二
基于上述分配模式二，在本模式下根据用户终端的数据错误反馈信号中的循环移位值，确定所述用户终端的优先级；当所述用户终端为第一优先级时，向所述用户终端重传数据；当所述用户终端为第二优先级时，降低向所述用户终端所在的组发送数据的码率。
本实施例提供的宽带集群系统组呼业务中用户的上行反馈方法，无线基站建立多个群组，并为每个群组分配对应的反馈信道，预设数量的反馈信道共同占用1RB时频域资源，提高了系统资源的利用率，基于实施例提供的上行反馈方法，使得空闲态用户终端上行反馈成为可能，能够保证组呼业务传输的可靠性，提高频谱利用率。
