Description
本申请要求在2015年12月04日提交中国专利局、申请号为201510884921.3、申请名称为“一种信息的发送和接收方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及无线通信技术领域,特别涉及一种信息的发送和接收方法及设备。
LTE(Long Term Evolution,长期演进)系统中,一个无线帧包含10个子帧。LTE TDD(LTE Time Division Duplexing,长期演进时分双工)系统中,收发数据在同一载波的不同时间完成,即上下行是在时间上以子帧粒度进行区分的。
TDD系统中的子帧包括下行子帧,上行子帧和特殊子帧,其中,特殊子帧包括DwPTS(Downlink Pilot Time Slot,下行导频时隙),GP(Guard Period,保护间隔)和UpPTS(Uplink Pilot Time Slot,上行导频时隙)三个部分,其中GP主要用于下行到上行的转换时间和上下行传输时延的补偿。LTE版本12以前的系统可以支持7种不同的上下行子帧配置(Uplink-downlink configuration),具体的配置如表1所示,其中D表示下行子帧,S表示特殊子帧,U表示上行子帧,0-6为上下行配置索引。在本申请文件中,上下行配置索引为0的帧结构也可称为上下行配置0,其余类似。表1中,上下行配置0、1、2和6的下上行转换周期为5ms,上下行配比3、4和5的下上行转换周期为10ms。
表1
LTE系统支持CA(Carrier Aggregation,载波聚合)技术,即可以把多个成员载波或服务小区同时分给一个UE(User Equipment,用户设备),用于支持更高的数据速率传输。本领域一般技术人员应当理解,服务小区即为载波。CA中有一个主服务小区和至少一个辅服务小区,且承载HARQ-ACK(Hybrid Automatic Repeat request-Acknowledgment,混合自动重传请求确认应答)的PUCCH(Physical Uplink Control Channel,物理上行控制信道)只发送在主服务小区上。
根据现有移动网络中的业务趋势,下行数据业务需求远远大于上行业务需求。从现有上下行配置可看出,能最大限度将频谱资源应用于下行数据业务传输的上下行配置为上下行配置5。如表1所示,在该上下行配置5下,一个无线帧最大有9个子帧可用于下行数据传输。
为了更好地匹配现有网络业务趋势,现有技术中引入了一种新的无线帧结构,使得一个无线帧中所有子帧均可用于下行数据传输,具体的帧结构的上下行配置如表2所示。
表2
如表2所示的上下行配置能使一个无线帧中的10个子帧都用于下行数据的传输,从而实现了最大限度将频谱资源应用于下行数据业务传输。
但是这种上下行配置,一个无线帧中仅包括下行子帧,一方面,使得SRS(Sounding Reference Signal,探测参考信号)无法在该上下行配置部署的服务小区上传输,从而使得该服务小区不能通过信道互易性提高Massive MIMO(Multiple-Input Multiple-Output,多入多出)的性能,大大限制了Massive MIMO能够带来的性能增益;另一方面,一个无线帧仅包括下行子帧,使得该服务小区对应的上行反馈信息,包括混合自动重传确认信息和信道状态信息等,只能通过另一个服务小区进行反馈,从而使得该上下行配置部署的服务小区不能独立工作;同时,从用户设备的角度来说,该上下行配置部署的服务小区只能作为辅服务小区,因此限制了该上下行配置部署的服务小区仅能为具有载波聚合能力的用户设备服务,限制了该上下行配置的应用场景。
综上所述,目前为实现最大限度将频谱资源应用于下行数据业务传输而引入的新的无线帧结构,不但限制了Massive MIMO可能带来的性能增益,而且使得通过该上下行配置部署的服务小区不能独立工作。

为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅仅是本申请的一部分实施例,而不是全部的实施例。基于本申请中的实施例,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它实施例,都属于本申请保护的范围。
下面结合说明书附图对本发明实施例作进一步详细描述。
本发明实施例主要应用于LTE系统,单载波或多载波聚合场景。
图1为适用于本发明实施例提供的技术方案的通信系统的示意图。该通信系统包括:用户设备(User Equipment,UE)100、基站101和核心网。采用本发明实施例提供的技术方案,由于服务小区对应的帧结构中一个无线帧中的所有子帧都能够用于物理下行共享信道的传输,实现最大限度将频谱资源应用于下行数据业务传输,从而较好地匹配现有下行业务远大于上行业务的业务趋势。
此外,由于服务小区对应的帧结构中一个无线帧包括第一特殊子帧,而该第一特殊子帧包括用于上行传输的符号,该用于上行传输的符号可用于上行控制信道传输,具体可包括混合自动重传请求确认传输、信道状态信息传输和/或调度请求传输,从而使得该服务小区对应的上行控制信息反馈可以不依赖于另一个服务小区,因此部署该上下行配置的服务小区能够独立工作;并且由于第一特殊子帧中包括的用于上行传输的符号还可用于SRS的传输,从而使得该服务小区上能够通过信道互易性提高Massive MIMO的性能,或提高链路自适应带来的增益。
下面对本发明实施例提供的技术方案进行详细说明。
图2是根据本发明一个实施例的发送和接收信息的方法的流程示意图,包括:
步骤200,确定服务小区的帧结构,该帧结构对应的一个无线帧包括至少一个第一特殊子帧,该无线帧中其余子帧为下行子帧,其中该第一特殊子帧包括用于下行传输的符号、保护时间GP和用于上行传输的符号,该上行传输包括混合自动重传请求确认上行控制信道传输和/或探测参考信号SRS传输,该下行传输包括物理下行共享信道传输;
步骤201,基于该帧结构在该服务小区上发送和接收信息。
其中,本发明实施例中的执行主体可以为基站,也可以为UE。
需要说明的是,本发明的实施例中不限制第一特殊子帧的具体子帧结构。图3给出了一个子帧长度为1ms时,第一特殊子帧的子帧结构。图3所示的子帧结构中,第一特殊子帧包括12个用于下行传输的符号、时长为1个符号的保护时间(Guard Period,GP)和1个用于上行传输的符号。其中,对于用于下行传输的符号可以为OFDM符号,对于用于上行传输的符号可以为SC-OFDM符号。
在本发明实施例中,上行传输除了包括混合自动重传请求确认上行控制信道传输和/或探测参考信号SRS传输以外,还可以包括信道状态信息传输和/或调度请求的传输。
在具体实现时,通过在目前上下子帧配置的基础上增加新的上下行子帧配置,如表3所示。
表3
其中,x为大于6的正整数,S表示特殊子帧,S1为第一特殊子帧,D为下行子帧,U为上行子帧。
在本发明实施例中,上下行配置x对应的上下行配比为0:10,需要说明的是,本发明所有实施例中,假设服务小区的上下行配比为X:Y,可以表示该服务小区的帧结构中用于物理上行共享信道传输的子帧数与用于物理下行共享信道传输的子帧数的比为X:Y。由于该上下行配置x对应的上下行配比为0:10,即用于物理上行共享信道传输的子帧数为0,用于物理下行共享信道传输的子帧数10。因此能够实现一个无线帧中所有子帧都可用于物理下行共享信道传输,从而较好地匹配现有下行业务远大于上行业务的业务趋势。
另外,由于第一特殊子帧包括用于上行传输的符号,该用于上行传输的符号可用于承载上行控制信道传输的上行控制信息,其中上行控制信息可包括混合自动重传请求确认、信道状态信息和/或调度请求,从而使得该服务小区对应的上行控制信息反馈可以不依赖于另一个服务小区,因此部署该上下行配置的服务小区能够独立工作;同时,该用于上行传输的符号还可用于传输探测参考信号SRS,从而使得该服务小区上能够通过信道互易性提高Massive MIMO的性能。
可选的,在步骤201中,根据服务小区的上下行配置确定服务小区的帧结构,以表3为例,若表3中x的值7,若当前上下行配置为上下行配置7,则确定服务小区的帧结构为与上下行配置7对应的帧结构。
为实现一个无线帧中所有子帧都可用于物理下行共享信道传输,服务小区能够独立工作以及使得该服务小区上能够通过信道互易性提高Massive MIMO的性能,可选的,至少一个第一特殊子帧在无线帧中的子帧位置为至少一个子帧位置中的一个或多个,其中,至少一个子帧位置为上下行配置0的一个无线帧中上行子帧和特殊子帧对应的子帧位置,即第一特殊子帧在一
个无线帧中的子帧位置是上下行配置0一个无线帧中上行子帧和特殊子帧对应的子帧位置的子集。
从表3中可以看出,上下行配置0对应的上行子帧U和特殊子帧S的位置分别为1、2、3、4、6、7、8、9,则第一特殊子帧的位置可以为1、2,也可以为4、8、9,只要第一特殊子帧的位置对应的集合为集合{1、2、3、4、6、7、8、9}的子集即可,当第一特殊子帧的位置对应的集合为集合{1、2、3、4、6、7、8、9}的真子集时,较佳地,其它位置为下行子帧,例如第一特殊子帧的位置为1、2,则位置3、4、6、7、8、9为下行子帧。需要说明的是,上下行配置0对应的下行子帧D的位置还为下行子帧。
为简化实现方式,可选的,至少一个第一特殊子帧在无线帧中的子帧位置与至少一个子帧位置对应,其中,至少一个子帧位置为上下行配置0到上下行配置6中的一种上下行配置中,一个无线帧中上行子帧和特殊子帧对应的子帧位置,即第一特殊子帧在一个无线帧中的子帧位置与上下行配置0到上下行配置6中一种上下行配置一个无线帧中上行子帧和特殊子帧对应的子帧位置相同。
需要说明的是,较佳地,下行配置0到上下行配置6中下行子帧的位置在包含第一特殊子帧的无线帧中还是下行子帧的位置。
具体的,如表4所示,一个无线帧包括10个子帧,其中,子帧0和子帧5为下行子帧,子帧1、子帧2、子帧3、子帧4、子帧6、子帧7、子帧8和子帧9为第一特殊子帧;或子帧0、子帧4、子帧5和子帧9为下行子帧,子帧1、子帧2、子帧3、子帧6、子帧7和子帧8为第一特殊子帧;或子帧0、子帧3、子帧4、子帧5、子帧8和子帧9为下行子帧,子帧1、子帧2、子帧6和子帧7为第一特殊子帧;或子帧0、子帧5、子帧6、子帧7、子帧8和子帧9为下行子帧,子帧1、子帧2、子帧3和子帧4为第一特殊子帧;或子帧0、子帧4、子帧5、子帧6、子帧7、子帧8和子帧9为所述下行子帧,子帧1、子帧2和子帧3为第一特殊子帧;或子帧0、子帧3、子帧4、子帧5、子帧6、子帧7、子帧8和子帧9为下行子帧,子帧1和子帧2为第一特殊子帧;
或子帧0、子帧5和子帧9为下行子帧,子帧1、子帧2、子帧3、子帧4、子帧6、子帧7和子帧8为第一特殊子帧。
表4
其中,上下行配置7中第一特殊子帧S1的位置与上下行配置0中上行子帧0和特殊子帧S的位置相同,上下行配置8中第一特殊子帧S1的位置与上下行配置1中上行子帧0和特殊子帧S的位置相同,上下行配置9中第一特殊子帧S1的位置与上下行配置2中上行子帧0和特殊子帧S的位置相同,上下行配置10中第一特殊子帧S1的位置与上下行配置3中上行子帧0和特殊子帧S的位置相同,上下行配置11中第一特殊子帧S1的位置与上下行配置4中上行子帧0和特殊子帧S的位置相同,上下行配置12中第一特殊子帧S1的位置与上下行配置5中上行子帧0和特殊子帧S的位置相同,上下行配置13中第一特殊子帧S1的位置与上下行配置6中上行子帧0和特殊子帧S的位置相同,需要说明的是,仅以表4中上下行配置x(x取值为7、8、9、……、13)与子帧结构的对应关系,以及x的取值为例对子帧的结构进行说明,但本发明不限于表4中x的取值,以及上下行配置x与子帧结构的对应关系。
由于第一特殊子帧在一个无线帧中的子帧位置是上下行配置0一个无线帧中上行子帧和特殊子帧对应的子帧位置的子集,或第一特殊子帧在一个无线帧中的子帧位置与上下行配置0到上下行配置6中一种上下行配置一个无线帧中上行子帧和特殊子帧对应的子帧位置相同,从而当配置上行控制信息
如周期信道状态信息和/或探测参考信号SRS在该服务小区上反馈时,可重用现有LTE系统的对应机制,节省了标准复杂度和降低了实现复杂度;另外,也保护了该服务小区的上行控制信息和/或SRS受到邻小区下行信号的干扰,因为无论邻小区的上下行配置是哪一种,该服务小区的上行控制信息和/或SRS都仅与邻小区的上行传输碰撞,但由于与邻小区的上行传输碰撞造成的干扰较小,可忽略不记。
当服务小区为用户设备的辅服务小区时,可选地,服务小区为用户设备的辅服务小区,至少一个第一特殊子帧在无线帧中的子帧位置为至少一个子帧位置中的一个或多个,其中,至少一个子帧位置为用户设备的主服务小区上的一个无线帧中下行子帧对应的子帧位置,即第一特殊子帧在一个无线帧中的子帧位置,是该用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置的子集;其中,包含第一特殊子帧的无线子帧中的其它位置为下行子帧。
具体的,当用户设备的主服务小区上一个无线帧的帧结构如表4中上下配置13对应的无线帧结构时,用户设备的辅服务小区上的无线帧结构如表5所示。
表5
仅以表5中上下行配置x(x取值为14、15、16)与子帧结构的对应关系,以及x的取值为例对子帧的结构进行说明,但本发明不限于表5中x的取值,以及上下行配置x与子帧结构的对应关系。
为简化实现方式,当服务小区为用户设备的辅服务小区时,可选地,服务小区为用户设备的辅服务小区,至少一个第一特殊子帧在无线帧中的子帧
位置与至少一个子帧位置对应,其中,至少一个子帧位置为用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置,即第一特殊子帧在一个无线帧中的子帧位置,与用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置相同;其中,下行子帧的位置与用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置相同。
具体的,当用户设备的主服务小区无线帧的帧结构为上下行配置0对应的无线帧结构时,则辅服务小区无线帧中子帧0和子帧5为第一特殊子帧,子帧1、子帧2、子帧3、子帧4、子帧6、子帧7、子帧8和子帧9为下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置1对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧4、子帧5和子帧9为第一特殊子帧,子帧1、子帧2、子帧3、子帧6、子帧7和子帧8为下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置2对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧3、子帧4、子帧5、子帧8和子帧9为所述特殊子帧,子帧1、子帧2、子帧6和子帧7为所述下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置3对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧5、子帧6、子帧7、子帧8和子帧9为所述特殊子帧,子帧1、子帧2、子帧3和子帧4为所述下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置4对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧4、子帧5、子帧6、子帧7、子帧8和子帧9为所述特殊子帧,子帧1、子帧2和子帧3为所述下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置5对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧3、子帧4、子帧5、子帧6、子帧7、子帧8和子帧9为所述特殊子帧,子帧1和子帧2为所述下行子帧;
当用户设备的主服务小区无线帧的帧结构为上下行配置6对应的无线帧结构时,则辅服务小区无线帧中子帧0、子帧5和子帧9为所述特殊子帧,子帧1、子帧2、子帧3、子帧4、子帧6、子帧7和子帧8为所述下行子帧。
因此当服务小区为用户设备的辅服务小区时,由于第一特殊子帧在一个无线帧中的子帧位置,是用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置的子集,或第一特殊子帧在一个无线帧中的子帧位置,与用户设备的主服务小区上一个无线帧中下行子帧对应的子帧位置相同,使得该用户设备能够在该服务小区第一特殊子帧中给基站发送的上行控制信息和/或探测信号SRS不与该用户设备的主服务小区上的上行传输碰撞,一方面可以避免在功率受限时,由于与主服务小区的上行传输碰撞而被丢弃,另一方面不用与主服务小区上的上行传输分功率从而保证性能;再则,对于不具备上行载波聚合能力的用户设备,由于该服务小区第一特殊子帧仅与主服务小区的下行子帧碰撞,因此可以当主服务小区为下行子帧时在辅服务小区发送上行传输,当主服务小区为上行子帧时在主服务小区上发送上行传输,从而使得对于仅具有上行单载波能力的用户设备也能在该辅服务小区上发送上行控制信息和/或SRS,提高链路自适应带来的增益。
其中,本发明实施例不对服务小区的帧结构中每个子帧的长度做限制,较佳地,每个子帧的长度为1ms。
基于同一发明构思,本发明实施例中还提供了信息发送和接收设备,由于本发明实施例信息发送和接收设备对应的方法为信息发送和接收方法,因此本发明实施例设备的实施可以参见方法的实施,重复之处不再赘述。

应注意,尽管图5所示的设备仅仅示出了处理器510、收发器520和存储器530,但是在具体实现过程中,本领域的技术人员应当明白,该设备还包含实现正常运行所必须的其他器件。同时,根据具体需要,本领域的技术人员应当明白,该设备还可包含实现其他附加功能的硬件器件。此外,本领域的技术人员应当明白,该设备也可仅仅包含实现本发明实施例所必须的器件或模块,而不必包含图5中所示的全部器件。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流
程,是可以通过计算机程序来指令相关的硬件来完成,上述的程序可存储于一计算机可读取存储介质中,该程序在执行时,可包括如上述各方法的实施例的流程。其中,上述的存储介质可为磁盘、光盘、只读存储记忆体(ROM:Read-Only Memory)或随机存储记忆体(RAM:Random Access Memory)等。
从上述内容可以看出:本发明实施例确定服务小区的帧结构,其中帧结构对应的一个无线帧包括至少一个第一特殊子帧,该无线帧中其余子帧为下行子帧,第一特殊子帧包括用于下行传输的符号、保护时间GP和用于上行传输的符号,上行传输包括混合自动重传请求确认上行控制信道传输和/或探测参考信号SRS传输,下行传输包括物理下行共享信道传输;基于所述帧结构在所述服务小区上发送和接收信息。这种技术方案一方面由于服务小区对应的帧结构中一个无线帧中的所有子帧都能够用于物理下行共享信道的传输,实现最大限度将频谱资源应用于下行数据业务传输,从而较好地匹配现有下行业务远大于上行业务的业务趋势;另一方面,由于服务小区对应的帧结构中一个无线帧包括第一特殊子帧,而该第一特殊子帧包括用于上行传输的符号,该用于上行传输的符号可用于上行控制信道传输,具体可包括混合自动重传请求确认传输、信道状态信息传输和/或调度请求传输,从而使得该服务小区对应的上行控制信息反馈可以不依赖于另一个服务小区,因此部署该上下行配置的服务小区能够独立工作;此外,由于第一特殊子帧中包括的用于上行传输的符号还可用于SRS的传输,从而使得该服务小区上能够通过信道互易性提高Massive MIMO的性能,或提高链路自适应带来的增益。
本领域内的技术人员应明白,本发明的实施例可提供为方法、系统、或计算机程序产品。因此,本发明可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且,本发明可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本发明是参照根据本发明实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图
和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器,使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中,使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品,该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上,使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理,从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
尽管已描述了本发明的优选实施例,但本领域内的技术人员一旦得知了基本创造性概念,则可对这些实施例作出另外的变更和修改。所以,所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然,本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
