发明人通过研究发现,由于在3GPP R16中的超级上行技术所使用的两个载波中,一个载波仅用于单天线上行传输,因此无法有效提升上行带宽利用率。
据此,本公开提供一种终端能力上报方案,能够有效提升上行带宽利用率。
图1是根据本公开一些实施例的终端能力上报方法的流程示意图。在一些实施例中,下面的终端能力上报方法步骤由用户终端执行。
步骤101,获取终端能力信息。
在一些实施例中,终端能力信息包括支持上行双发射机切换的频段组合(Band Combination)中的每个频段对(Band Pair),每个频段对的切换时间,其中每个频段对中包括的第一载波和第二载波均用于上行双发射机传输。例如,一个频段对为3.5GHz频段和2.1GHz频段,第一载波为3.5GHz频段的载波,第二载波为2.1GHz频段的载波。
例如,每个频段对的切换时间为35μs、140μs或210μs。每个频段对的切换时间表示在该频段对中由一个频段切换到另一个频段所需的切换时间。
在一些实施例中,终端能力信息还包括:每个频段对在进行上行切换时是否对频段组合内的频段造成下行中断的指示信息。指示信息包括:针对每个频段对,频段组合内的每个频段是否需要下行中断。
例如,在FDD(Frequency Division Duplex,频分双工)+TDD(Time Division Duplex,时分双共)的CA(Carrier Aggregation,载波聚合)的情况下,对每个做发射机切换的频段对,上报是否对包括该频段对的频段组合内的一个或多个频段带来下行中断。
例如,若频段组合中包括频段A、B、C和D,频段对(A,B)支持上行双发射机切换,则用户终端需要针对频段A、B、C和D分别上报是否需要下行中断。
在一些实施例中,终端能力信息还包括:在CA切换情况下频段组合支持的第一切换选项和第二切换选项中的至少一项。
例如,第一切换选项如表1所示。
情况1 0T+2T
情况2 2T+0T
表1
如表1所示,在情况1中,两个发射机均利用第二载波进行上行传输。在情况2中,两个发射机均利用第一载波进行上行传输。
例如,第二切换选项如表2所示。
情况1 1T+1T
情况2 0T+2T
情况3 2T+0T
表2
如表2所示,在情况1中,两个发射机中的一个使用第一载波进行上行传输,两个发射机中的另一个使用第二载波进行上行传输。在情况2中,两个发射机均利用第二载波进行上行传输。在情况3中,两个发射机均利用第一载波进行上行传输。
在一些实施例中,终端能力信息还包括与上行数据信道的MIMO(Multiple Input Multiple Output,多输入多输出)层数相关联的能力信息、SRS(Sounding Reference Signal,探测参考信号)切换的端口数能力信息、频段组合的功率等级能力信息和频段组合内的频段的功率等级能力信息中的至少一项。
在步骤102,向基站上报终端能力信息。
在本公开上述实施例提供的终端能力上报方法中,通过将支持上行双发射机切换的频段组合中的每个频段对,每个频段对的切换时间上报给基站,由于每个频段对中包括的第一载波和第二载波均用于上行双发射机传输,因此基站能够给接收到的终端能力上报信息配置用户终端进行上行双发射机切换,有效提升上行带宽利用率。
图2是根据本公开一个实施例的用户终端的结构示意图。如图2所示,用户终端包括获取模块21和上报模块22。
获取模块21获取终端能力信息。
在一些实施例中,终端能力信息包括支持上行双发射机切换的频段组合中的每个频段对,每个频段对的切换时间,其中每个频段对中包括的第一载波和第二载波均用于上行双发射机传输。
例如,每个频段对的切换时间为35μs、140μs或210μs。
在一些实施例中,终端能力信息还包括:每个频段对在进行上行切换时是否对频段组合内的频段造成下行中断的指示信息。指示信息包括:针对每个频段对,频段组合内的每个频段是否需要下行中断。
例如,在FDD+TDD的CA的情况下,对每个做发射机切换的频段对,上报是否对包括该频段对的频段组合内的一个或多个频段带来下行中断。
例如,若频段组合中包括频段A、B、C和D,频段对(A,B)支持上行双发射机切换,则用户终端需要针对频段A、B、C和D分别上报是否需要下行中断。
在一些实施例中,终端能力信息还包括:在CA切换情况下频段组合支持的第一切换选项和第二切换选项中的至少一项。
例如,第一切换选项如表1所示。第二切换选项如表2所示。
在一些实施例中,终端能力信息还包括与上行数据信道的MIMO层数相关联的能力信息、SRS切换的端口数能力信息、频段组合的功率等级能力信息和频段组合内的频段的功率等级能力信息中的至少一项。
上报模块22向基站上报终端能力信息。
图3是根据本公开另一个实施例的用户终端的结构示意图。如图3所示,用户终端包括存储器31和处理器32。
存储器31用于存储指令。处理器32耦合到存储器31。处理器32被配置为基于存储器存储的指令执行实现如图1中任一实施例涉及的方法。
如图3所示,用户终端还包括通信接口33,用于与其它设备进行信息交互。同时,该用户终端还包括总线34,处理器32、通信接口33、以及存储器31通过总线34完成相互间的通信。
