当1<i<W时,UE承载i个业务的情况可以单独划分为一种类型,也可以和UE承载i+1或i-1个业务的情况划分为一类。
下面结合附图将对本发明实施例的技术方案作进一步的详细描述。
实施例一:
如图2所示,UE1有2个上行业务,采用相同的发射方式,即单天线端口发射模式。对应多业务DCI12,传输模式为TM12。由于只有2种业务,所以DCI12采用S1=[1、2、4、8]控制信道信元CCE聚合度,M1=[6、6、2、2]候选级进行调度和检测。
如图3所示,UE2有3个下行业务,采用不同的发射方式,即分别采用发射分集、大延迟CDD以及端口7-14的8层波束赋形发射模式。对应多业务DCI15,传输模式为TM15。由于有3种业务,所以DCI15采用S2=[2、4、8、16]CCE聚合度,M2=[2、2、2、2]候选级进行调度和检测。
本实施例中,DCI15的内容包括:1)第1#业务属性包,该业务采用资源分配类型0,占用0~3#资源块RB,MCS=4,RV=0,NDI=0等调度信息;2)第2#业务属性包,该业务采用资源分配类型0,占用8~35#RB,transport block1的MCS=16,RV=0,NDI=0,transport block2的MCS=16,RV=0,NDI=0等调度信息。3)第3#业务属性包,该业务采用资源分配类型0,占用40~79#RB,transport block1的MCS=20,RV=0,NDI=0,transport block2的MCS=25,RV=0,NDI=0,Antenna port(s),scrambling identity and number of layers=7等调度信息。在DCI的UE属性中定义Carrier indicator=0,SRS request=1等信息组成UE属性包。三个业务属性包顺序级联在尾部附加上UE
属性包,组成UE2的多业务DCI15。
如图4所示,UE3有4个下行业务,分别采用发射分集、发射分集、大延迟CDD以及闭环空间复用发射模式。对应多业务DCI18,传输模式为TM18。由于有4种业务,所以DCI18采用S3=[4、8、16、32]CCE聚合度,M3=[2、2、2、2]候选级进行调度和检测。
在UE3有4个下行业务的情况下,DCI18的内容包括:1)第1#业务属性包,该业务采用资源分配类型0,占用0~7#RB,MCS=9,RV=0,NDI=0等调度信息;2)第2#业务属性包,该业务采用资源分配类型0,占用8~19#RB,MCS=15,RV=0,NDI=0等调度信息;3)第3#业务属性包,该业务采用资源分配类型0,占用32~47#RB,transport block1的MCS=20,RV=0,NDI=0,transport block2的MCS=20,RV=0,NDI=0,Precoding information=2等调度信息。4)第4#业务属性包,该业务采用资源分配类型0,占用80~91#RB,transport block1的MCS=25,RV=0,NDI=0,transport block2的MCS=25,RV=0,NDI=0,Precoding information=2等调度信息。在DCI的UE属性中定义Carrier indicator=1,SRS request=1等信息组成UE属性包。三个业务属性包顺序级联在尾部附加上UE属性包,组成UE3的多业务DCI18。
本发明实施例提出的多业务控制信道设计提高了同一UE多业务情况时的控制信道传输频谱利用率,选用合适的DCI聚合度集合,保证了控制信道的传输性能,也降低了盲检测次数,从而完成了高效的、可靠的多业务通信。
同时,本申请还提供一种多业务控制信道发送的装置,如图5所示,应用于物理下行控制信道PDCCH,所述装置包括处理器、程序存储设备和数据存储设备,还包括:
配置模块11,适用于当用户设备UE承载N个业务时,配置多业务下行控制信息DCI,1≤N;还适用于为所述UE承载N个业务时的DCI配置相应
的聚合度以及候选级;

同一类型的情况下配置聚合度sp以及配置候选级度mp。
较佳地,
所述业务调度信息包括调制方式、资源分配、HARQ重传和预编码。
本发明还可有其它多种实施例。例如,LTE下行多业务DCI格式定义有多种,这里可以定义若干适用与实际的通信应用场景的典型格式。同时,考虑到承载业务个数的情况会导致DCI长度不同,所以灵活地定义合适的CCE聚合度集合可以保证DCI的传输检测性能。聚合度集合的合理分类,也减少了DCI检测次数。在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
以上所述仅为本发明的优选实施例而已,并不用于限制本发明,对于本领域的技术人员来说,本发明可以有各种更改和变化。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件完成,所述程序可以存储于计算机可读存储介质中,如只读存储器、磁盘或光盘等。可选地,上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现,相应地,上述实施例中的各模块/模块可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。本申请不限制于任何特定形式的硬件和软件的结合。
