本发明的基本思想是: 在用户设备中实现一个功率放大器对应驱动多 个天线, 使用户设备支持多天线发射。
下面结合附图对技术方案的实施作进一步的详细描述。
一种用户设备中功放天线的配置装置, 该装置包括: 该装置包括: 现 有的基带处理单元和现有的射频前端; 该装置还包括: 天线对应驱动单元, 用于实现用户设备中的一个功率放大器对应驱动多个天线, 使用户设备支 持多天线发射。
这里, 天线对应驱动单元进一步包括: 合路器、 功率放大器和分离模 块。 其中, 合路器用于将来自于多个射频前端的多路射频信号合并成一路 后, 输入功率放大器。 功率放大器用于将来自于合路器的一路合并信号放 大后, 输入分离模块。 分离模块用于将来自于功率放大器的一路放大后的 合并信号分离后, 对应驱动多个天线。

这里, 分离模块进一步用于对放大后的合并信号分离时所采用的分离 方式, 与合路器对射频信号合并时所采用的合并方式相对应。
具体来说, 分离模块进一步用于采用的分离方式具体为频分方式时, 合路器采用的合并方式具体为频分方式; 或者, 分离模块进一步用于采用 的分离方式具体为码分方式时, 合路器采用的合并方式具体为码分方式。
一种用户设备中功放天线的配置方法, 该方法包括: 实现用户设备中 的一个功率放大器对应驱动多个天线, 使用户设备支持多天线发射。
这里, 实现一个功率放大器对应驱动多个天线具体包括: 一个合路器 将来自于多个射频前端的多路射频信号合并成一路后, 输入一个功率放大 器; 功率放大器将来自于合路器的一路合并信号放大后, 输入一个分离模 块; 分离模块将来自于功率放大器的一路放大后的合并信号分离后, 对应 驱动多个天线。
这里, 用户设备中仅包括一个功率放大器时, 相对应的, 合路器的数 量为一个, 分离模块的数量为一个。 此时, 实现对应驱动多个天线具体包 括: 一个功率放大器与一个合路器和一个分离模块相结合, 对应驱动用户 设备能支持的所有多个天线。
这里, 分离模块对放大后的合并信号分离时所采用的分离方式, 比如 频分方式或码分方式, 与合路器对射频信号合并时所采用的合并方式相对 应。 合并方式也可以是频分方式或码分方式。
综上所述, 本发明在用户设备中设计功率放大器时, 不局限于由每个 天线必须唯一对应一个功率放大器, 而是将用户设备中的每个功率放大器 对应多个天线, 通过每个功率放大器驱动多个天线实现多天线技术的支持, 从而, 采用本发明设计的这种一个功率放大器用于多个发射天线的配置装 置, 在支持多天线发射的用户设备中能节省功率放大器的数量, 节省成本, 从而, 不仅能大大降低用户设备的设计复杂度, 而且能大大降低用户设备 的功耗。
本发明主要包括以下内容:
针对装置而言, 本发明区别于现有技术, 在支持多天线发射的用户设 备中增加了合路器, 且该合路器作为一个功率放大器的前端设备, 用于将 来自于射频前端的射频信号合并后, 输入这个功率放大器。 相应于增加的 合路器, 在支持多天线发射的用户设备中还增加了分离模块, 且该分离模 块作为这个功率放大器的后端设备, 用于将来自于功率放大器的输出信号 分离后, 再驱动这个功率放大器所对应的多天线。
其中, 针对不同的通信系统而言, 对信号的合并和分离所采用的方式 可能互相造成影响, 因此在实现中可以考虑使用频分或码分的方式对信号 进行合并、 分离。 对于分离模块, 相对应于合路器的不同信号合并方式, 分离模块使用相对应的分离方式分离信号。 比如, 当前合路器采用频分的 方式对信号进行合并时, 分离模块需相对应的也采用频分的方式对信号进 行分离; 当前合路器采用码分的方式对信号进行合并时, 分离模块需相对 应的也采用码分的方式对信号进行分离。
总之, 采用本发明的配置装置, 一个功率放大器对应多个天线, 结合 使用这个功率放大器前端的合路器, 和这个功率放大器后端的分离模块, 能将这个功率放大器的输出信号分离, 以用于驱动用户设备所支持的多个 天线。 本发明的配置装置是一种发射装置, 可应用于具备多天线发射能力 的用户设备中。
针对方法而言, 本发明的配置过程包括: 多路基带处理单元输出多路 基带信号; 多路基带信号分别送入多个射频前端; 多个射频前端输出的射 频信号分别送入一个合路器; 一个合路器输出合并信号后送入一个功率放 大器; 一个功率放大器输出信号进入一个分离模块; 一个分离模块对信号 分离后分别驱动多个天线。
以下对本发明进行举例阐述。
系统实施例一:
如图 1所示, 本实施例为用户设备中一个功率放大器对应两个天线的 配置装置, 该装置包括: 两个基带处理单元、 两个射频前端、 一个合路器、 一个功率放大器和一个分离模块。 本实施例中, 由一个功率放大器对应控 制驱动两个天线。 装置中仅包括一个功率放大器。
其中, 两个基带处理单元用于将输入的两路射频信号分别处理成基带 信号后, 将两路基带信号分别输入两个射频前端。 两个射频前端用于将两 路基带信号分别处理成射频信号后, 将两路射频信号分别输入同一个合路 器。 一个合路器用于将两路射频信号合并为合并信号后, 将一路合并信号 输入同一个功率放大器。 一个功率放大器用于将一路合并信号放大后, 输 入同一个分离模块。 一个分离模块用于将一路放大后的合并信号分离成两 路信号后, 分别驱动两个天线。
系统实施例二:
如图 3 所示, 本实施例为用户设备中一个功率放大器对应四个天线的 配置装置, 该装置包括: 四个基带处理单元、 四个射频前端、 一个合路器、 一个功率放大器和一个分离模块。 本实施例中, 由一个功率放大器对应控 制驱动四个天线。 本实施例与上述系统实施例一的一功率放大器对应控制 驱动两天线的结构类似, 装置中仅包括一个功率放大器。
其中, 四个基带处理单元用于将输入的四路射频信号分别处理成基带 信号后, 将四路基带信号分别输入四个射频前端。 四个射频前端用于将四 路基带信号分别处理成射频信号后, 将四路射频信号分别输入同一个合路 器。 一个合路器用于将四路射频信号合并为合并信号后, 将一路合并信号 输入同一个功率放大器。 一个功率放大器用于将一路合并信号放大后, 输 入同一个分离模块。 一个分离模块用于将一路放大后的合并信号分离成两 路信号后, 分别驱动四个天线。
系统实施例三:
如图 4所示, 本实施例为用户设备中两个双天线叠加时一个功率放大 器对应两个天线的配置装置, 该装置包括: 四个基带处理单元、 四个射频 前端、 两个合路器、 两个功率放大器和两个分离模块。 本实施例中, 由两 个功率放大器的每一个功率放大器分别对应控制驱动两个天线。 装置中包 括两个功率放大器。 这样做的好处是: 以上系统实施例二仅包括一个功率 放大器, 一个功率放大器要实现对应控制驱动四个天线时需要使用的功率 放大器功率较大, 而本实施例采用两个功率放大器, 每一个功率放大器分 别对应控制驱动两个天线, 能减少每一个功率放大器的功率, 从而比以上 系统实施例二更优化, 能避免在用户设备中使用更大功率的功率放大器。 而且, 用户设备中功率放大器数量上的减少可以减小电流消耗, 有利于用 户设备的节电。 该装置虽然也是支持四天线的发射结构, 但是, 使用两个 发射天线叠加的发射结构, 达到优化用户设备设计的目的。 本实施例的核 心就是: 四路基带信号经过射频前端处理后合并到两个独立的功率放大器 中, 并经过这两个功率放大器去分别驱动两个天线, 从而实现用户设备对 四天线的支持。
其中, 四个基带处理单元用于将输入的四路射频信号分别处理成基带 信号后, 将四路基带信号分别输入四个射频前端。 四个射频前端用于将四 路基带信号分别处理成射频信号后, 将每两路射频信号分别输入同一个合 路器。 两个合路器用于将每两路射频信号合并为合并信号后, 将每一路合 并信号输入同一个功率放大器。 两个功率放大器用于将每一路合并信号放 大后, 输入同一个分离模块。 两个分离模块用于将每一路放大后的合并信 号分离成两路信号后, 分别驱动四个天线。
方法实施例: 用户设备中一个功率放大器对应两个天线的情况。
此时, 采用的装置包括两个基带处理单元、 两个射频前端、 一个合路 器、 一个功率放大器和一个分离模块。 由一个功率放大器对应控制驱动两 个天线。 装置中仅包括一个功率放大器, 用户设备为手机, 以手机上使用 1 个 23dBm功率放大器为例, 与使用 2个 20dBm功率放大器等效。
本实施例中, 频分方式的功率放大器天线配置信号处理流程包括以下 步驟:
步驟 101、 两个基带处理单元输出两路基带信号。
步驟 102、 两路基带信号分别送入两个射频前端。
步驟 103、 两个射频前端输出两路射频信号分别送入同一个合路器。 步驟 104、 这个合路器输出合并信号并送入一个功率放大器。
步驟 105、 这个功率放大器将输出信号送入一个分离模块。
步驟 106、 这个分离模块对信号分离后分别驱动两个天线。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
