下面通过附图和实施例， 对本发明实施例的技术方案做进一步的详细描 述。 无线通信系统（例如全球移动通信系统 GSM ) 的跳频技术可以分为基带 现有技术中基站只包括一个多载波模块， 而多载波模块工作的频点是有 一定范围的， 例如， 多载波模块可以处理的跳频频点的频带范围在 fl与 fL之 间。 而为了拓宽小区内跳频频点的频带范围， 提升网络性能， 增强多载波模 块的适应能力， 可以为基站小区设置多个多载波模块， 每个多载波模块对应 不同的频段， 多个多载波模块之间进行互连， 不同频点的跳频数据通过不同 的多载波模块进行收发， 可以实现多载波小区跳频频点的分布范围超过单个 多载波模块的收发带宽范围， 扩展跳频技术的适用场景。
图 1为本发明第一实施例的基站的结构示意图， 包括至少两个多载波模 块 11 (图 1中所示为 1 , 2...N ) , 所述至少两个多载波模块之间互连， 所述 至少两个多载波模块中的至少一个多载波模块用于确定待收发的数据的跳 频频点及该跳频频点所属于的多载波模块， 并将该跳频频点通知给该跳频 频点属于的多载波模块， 由该跳频频点属于的多载波模块对待收发的数据 进行收发处理。 以一个多载波模块进行确定为例， 所述一个多载波模块用 于确定待收发的数据的跳频频点及该跳频频点所属于的多载波模块， 在该 调频频点属于另一个多载波模块时， 所述另一个多载波模块对待收发的数 据进行收发处理。 或者， 在该调频频点属于所述一个多载波模块时， 所述 一个多载波模块对待收发的数据进行收发处理。
本实施例中通过多个多载波模块之间的连接， 可以将待收发的数据传 输给对应的多载波模块进行跳频收发处理， 使跳频频点并不限定于单一的 多载波模块的频点范围， 可以扩展跳频技术的适用范围。
具体的， 在实施时可以设置每个多载波模块都具有确定待收发的数据 的跳频频点及该跳频频点属于哪个多载波模块的能力， 或者， 设置一个多 载波模块具有确定待收发的数据的跳频频点及该跳频频点属于的多载波模 块。 根据不同的情况， 多载波模块之间的连接关系是不同的。 当每个多载波模块都具有确定待收发的数据的跳频频点及该跳频频点 属于的多载波模块的能力时，各多载波模块 11之间可以如图 1所示的进行 串联， 或者， 各多载波模块之间可以进行两两连接。 当只有一个多载波模 块具有确定待收发的数据的跳频频点及该跳频频点属于哪个多载波模块的 能力时， 其他的不具有上述能力的多载波模块均需要与该具有上述能力的 多载波模块连接。
跳频频点属于的多载波模块具体为： 确定多载波模块或者与所述确定 多载波模块不同的另一个多载波模块， 该确定多载波模块用于确定待收发 的数据的跳频频点及该跳频频点属于的多载波模块； 即当一个多载波模块 用来确定待收发的数据的跳频频点及该跳频频点属于哪个多载波模块时， 该执行确定功能的多载波模块为确定多载波模块。
图 2为本发明第二实施例的基站的结构示意图， 本实施例多载波模块之 间两两连接， 每个多载波模块都具有确定待收发的数据的跳频频点及该跳 频频点属于哪个多载波模块的能力。 本实施例以三个多载波模块为例， 可 以理解的是， 当多载波模块为两个或四个以上时本实施例也适用。 参见图 2 , 本实施例中基站包括三个多载波模块 21 , 三个多载波模块之间两两连 接， 每个多载波模块均可以用于确定待收发的数据的跳频频点及该跳频频 点属于的多载波模块， 并在该跳频频点属于的多载波模块为另一个多载波 模块时， 将该跳频频点通知给该另一个多载波模块， 由该跳频频点属于的 该另一个多载波模块对该待收发的数据进行收发处理。 其中， 每个多载波 模块 21包括基带处理单元 211和中射频单元 212 ,每个多载波模块中的基 带处理单元 211两两连接实现多载波模块之间的两两连接。 具体地， 基带 处理单元 211之间可以通过高速总线进行连接。
其中， 本实施例中的多载波模块包括的基带处理单元 211和中射频单 元 212可以釆用现有技术实现，多载波模块 21具备基带跳频或射频跳频的 能力。 本实施例中通过多个多载波模块之间的连接， 可以将待收发的数据由 对应的多载波模块进行处理， 使跳频频点并不限定于单一的多载波模块的 频点范围， 可以扩展跳频技术的适用范围。
图 3为本发明第三实施例的基站的结构示意图， 与第二实施例不同的 是，本实施例是每个多载波模块 31中的基带处理单元 311均与其它多载波模 块 31中的中射频单元 312连接。
本实施例一个多载波模块中的基带处理单元直接与另一多载波模块中 的中射频单元连接， 待收发的数据不需要通过其它基带处理单元的转发， 可以提高运行速度。
图 4为本发明第四实施例的基站的结构示意图， 本实施例针对一个多载 波模块具有确定待收发的数据的跳频频点及该跳频频点属于的多载波模块 的能力的情况。参见图 4 , 本实施例的多载波模块包括一个第一多载波模块 41 (下面简称为第一模块）和至少一个（图中所示为 1 ...N ) 第二多载波模 块 42 (下面简称为第二模块） ， 所述至少一个第二模块 42分别与第一模块 41连接， 第一模块 41用于确定待收发的数据的跳频频点及该跳频频点属于 的多载波模块， 并在该跳频频点属于的多载波模块为某个第二模块时， 将 该跳频频点通知给该跳频频点属于的多载波模块， 由该跳频频点属于的多 载波模块对该待收发的数据进行收发处理。
其中， 图 4中第一模块 41和各个第二模块 42可以均包括基带处理单元和中 射频单元， 且第一模块 41中的第一基带处理单元 411分别与各个第二模块 42中 的第二基带处理单元 421连接。 即第一模块 41包括第一基带处理单元 411和第 一中射频单元 412 , 第二模块 42包括第二基带处理单元 421和第二中射频单元 422。 第一模块 41中的第一基带处理单元 411用于确定待收发数据的跳频频点 及该跳频频点属于的中射频单元； 进一步地， 在该跳频频点属于的中射频单 元所在多载波模块为第二模块时， 将该跳频频点通知给该跳频频点属于的多 载波模块。 本实施例中通过多个多载波模块之间的连接， 可以将待收发的数据传 输给对应的多载波模块进行处理， 使跳频频点并不限定于单一的多载波模 块的频点范围， 可以扩展跳频技术的适用范围。
图 5为本发明第五实施例的基站的结构示意图， 与图 4所示的实施例类 似， 本实施例的多载波模块包括一个第一多载波模块 51 (下面简称为第一 模块）和至少一个（图中所示为 1 ...N )第二多载波模块 52 (下面简称为第 二模块）， 本实施例的第一模块 51包括第一基带处理单元 511和第一中射频 单元 512 , 第二模块 52包括第二基带处理单元 521和第二中射频单元 522。 与 图 4所示的实施例不同的是，本实施例是第一模块 51中的第一基带处理单元 511分别与所述至少一个第二模块 52中的第二中射频单元 522互相连接。
本实施例一个多载波模块 （即确定多载波模块） 直接与另一多载波模 块中的中射频单元连接， 待收发的数据不需要基带处理单元的转发， 可以 提高运行速度。
图 6是本发明第六实施例的基站的结构示意图，本实施例的多载波模块 包括一个第一多载波模块 61 (下面简称为第一模块） 和至少两个 （图中所 示为 1 ...N ) 第二多载波模块 62 (下面简称为第二模块） ， 与第四、 五实施 例不同的是， 本实施例是将基带处理单元从第二多载波模块中分离出去， 仅在第一多载波模块中保留基带处理单元。 即本实施例的第一模块 61包括 基带处理单元 611 , 而不包括中射频单元； 第二模块 62包括中射频单元 622 , 而不包括基带处理单元。 所述第一模块的基带处理单元用于确定待收发数 据的跳频频点及该跳频频点属于的第二模块； 该跳频频点属于的第二模块 用于对该待收发的数据进行收发处理。
本实施例中多个中射频单元共享一个基带处理单元， 实现基带集中处 理。
图 7为本发明第七实施例的基站跳频方法流程示意图， 包括如下步骤。 步骤 71 : 基带处理单元确定待收发数据的跳频频点。 步骤 72 : 基带处理单元确定该跳频频点属于的多载波模块。 步骤 73 : 基带处理单元将所述跳频频点通知给所述多载波模块， 该跳 频频点属于的多载波模块根据所述跳频频点对所述待收发数据进行收发处 理。
在每个多载波模块均包含中射频单元时， 分为该多载波模块 （即确定 多载波模块）自己进行收发处理和其它多载波模块进行收发处理两种情况， 即当一个多载波模块的基带处理单元确定该跳频频点属于该多载波模块， 则将该跳频频点发送给该多载波模块的中射频单元， 由该多载波模块的中 射频单元进行数据的收发处理； 当该多载波模块的基带处理单元确定该跳 频频点属于其他的多载波模块时， 将该跳频频点通知给该跳频频点属于的 其他的多载波模块的中射频单元， 由该跳频频点属于的多载波模块的中射 频单元进行数据的收发处理。
在基带集中处理时， 即多个中射频单元共享一个基带处理单元时， 基 带处理单元直接通知该跳频频点属于的多载波模块中的中射频单元。
其中， 对一个多载波模块来说， 所述多载波模块在自身内部可以进一 步对该待收发的数据进行射频跳频或者基带跳频。 射频跳频为： 所述基带 处理单元将该跳频频点通知给所述基站内与待收发数据对应的中射频单 元， 及将待发送的数据发送给所述基站内与该待收发数据对应的中射频单 元； 或者所述基带处理单元将该跳频频点通知给所述基站内与待收发数据 对应的中射频单元。 该中射频单元根据该跳频频点调节自身载波的输出频 率， 使自身载波的输出频率与该跳频频点相符， 并在该输出频率上发送该 待发送的数据或接收待接收的数据。 基带跳频为： 所述基带处理单元将该 跳频频点通知给所述基站内输出频率范围可以包含该跳频频点的中射频单 元， 及待发送的数据发送给所述基站内输出频率范围可以包含该跳频频点 的中射频单元； 或者所述基带处理单元将该跳频频点通知给所述基站内输 出频率范围可以包含该跳频频点的中射频单元。 该中射频单元发送该待发 送的数据或接收待接收的数据。 所述中射频单元可以通过调节对应中频单 元中的数控振荡器 （NCO , Numerical Control Oscillator ) 的频率， 或射频 单元的模拟射频锁相环的频率， 或中频单元中的数控振荡器 N C 0的频率和 射频单元的模拟射频锁相环的频率得到需要的跳频频点。
本实施例从一个多载波模块 （执行确定功能的多载波模块） 的基带处 理单元的角度进行了描述， 对本领域技术人员来讲， 该方法也可以由多载 波模块来完成。 具体可以包括如下步骤： 确定待收发数据的跳频频点； 确 定该跳频频点属于的多载波模块； 通过所述跳频频点属于的多载波模块在 所述跳频频点上对所述待收发数据进行收发处理。
进一步地， 在下行方向上， 该方法还可以包括： 若所述待发送数据对 应的基带处理单元属于一个多载波模块， 而确定的跳频频点属于的多载波 模块是另一个多载波模块， 将所述待发送数据从所述一个多载波模块传送 到所述另一个多载波模块， 由所述另一个多载波模块对所述待发送数据进 行处理得到射频数据， 并在确定的跳频频点上将所述射频数据发射出去。
或者， 在上行方向上， 该方法还可以包括： 若确定的跳频频点属于的 多载波模块是一个多载波模块， 而所述待接收数据对应的基带单元所属的 多载波模块为另一个多载波模块， 通过所述一个多载波模块对所述待接收 数据进行处理得到基带数据后， 将所述基带数据从所述一个多载波模块传 送给所述另一个多载波模块进行基带处理。
具体的， 图 8为本发明第七实施例对应的多载波模块结构示意图， 本实施 例对下行方向进行了描述， 以两个多载波模块实现下行跳频为例， 本实施例的 中射频单元具体包括中频单元、加法器、数模转换器（ Digital to Analog Converter DAC ) 、 模拟射频锁相环（Phase Lock Loop, PLL )和乘法器。 两个多载波模 块分别为第一多载波模块 81和第二多载波模块 82 , 其中第一多载波模块 81的频 点范围为 f！〜 φ, 第二多载波模块 82的频点范围为 gl~gk, 假定两个多载波模块 支持的发射瞬时带宽为 X ( MHz ) , 即 φ-ί!=Χ, gk-gl=X, 但 gk-fl>X。 第一多 载波模块 81包括第一基带处理单元 811和第一中频单元 812及第一加法器 813、 第一 DAC814、 第一 PLL815和第一乘法器 816, 第二多载波模块 82包括第二基 带处理单元 821和第二中频单元 822及第二加法器 823、 第二 DAC824、 第二 PLL825和第二乘法器 826。 第一多载波模块 81上被分配 n个载波， 第二多载波模 块 82上被分配 m个载波， 其中 n, m为正整数。 对射频跳频， 在逻辑上， 本实施 例中第一多载波模块 81中包括 n个分别与基带处理单元输出的各基带信号（即 基带数据 )对应的中频单元， 第二多载波模块中包括 m个分别与各基带信号对 应的中频单元。 假设第一多载波模块 81中的第一基带处理单元 811具备确定各 个载波的跳频频点属于哪个多载波模块的能力， 如果第一基带处理单元 811发 现待发送的数据的频点属于第二多载波模块 82的发射频率范围 （例如， 待发射 的数据的频点为 g2, g2位于 gl和 gk之间） ， 则第一基带处理单元 811将对应的 发射频点通过第一基带处理单元 811和第二基带处理单元 821之间的高速总线 通知给第二多载波模块 82, 以及第一基带处理单元 811将对应的基带数据（待 发送基带数据）通过该高速总线发送给第二多载波模块 82, 第二多载波模块 82 按照其接收的通知中的跳频频点信息进行射频跳频， 以及将待发送的基带数据 调制到对应的频点上发射到空口。 如果第一基带处理单元 811确定待发送数据 的频点属于第一多载波模块 81的范围（如频点为 fl ) , 则第一基带处理单元 811 直接将跳频频点通知给第一多载波模块 81中的对应该待发送数据的中频单元， 以及待发送数据发送给该对应该待发送数据的中频单元， 由该中频单元根据该 跳频频点调整数控振荡器的频率， 实现第一多载波模块内的射频跳频， 第一多 载波模块 81将待发送的数据调制到对应的频点上发射到空口。 通过两个多载波 模块的联合， 可以实现频点范围为 f！〜 gk的下行跳频， 由于 gk-fl>X, 实现了超 过单个多载波模块频点范围 （X ) 的下行跳频处理， 使下行跳频的适用范围更 广。
或者对基带跳频， 在物理上多载波模块有多个中频单元， 每个中频单 元在工作过程中不改变数控振荡器 NCO的输出频率， 也就是中频单元到射频 单元输出的调制频率是不变的。 基带处理单元按照跳频算法， 计算出下行数 据对应的频点， 通过交换器找到该频点对应的中频单元， 向该中频单元发送 数据， 实现下行基带跳频。 上面描述的是下行处理， 下面对上行处理进行描 述：
图 9为本发明第七实施例对应的多载波模块的结构示意图，本实施例对 上行方向进行了描述， 以两个多载波模块实现上行跳频为例， 本实施例的中 射频单元具体为包括中频单元、 模数转换器 ( Analog to Digital Converter, ADC ) 、 PLL和乘法器。 两个多载波模块分别为第一多载波模块 91和第二 多载波模块 92 , 其中第一多载波模块 91的频点范围为 fl~fd, 第二多载波模 块 92的频点范围为 gl ~gj , 两个多载波模块支持的发射瞬时带宽为 Y
( MHz ) , 即 fd-fl=Y, gj-gl=Y, 但 gj-fl>Y。 第一多载波模块 91包括第一 基带处理单元 911和第一中频单元 912及第一 ADC913、 第一 PLL914和第一 乘法器 915 , 第二多载波模块 92包括第二基带处理单元 921和第二中频单元 922及第二 ADC923、 第二 PLL924和第二乘法器 925。 第一多载波模块 91上 被分配 r个载波， 第二多载波模块 92上被分配 k个载波， 其中 r, k为正整数。 对射频跳频， 在逻辑上， 第一多载波模块 91中包括 r个分别与各基带信号对 应的中频单元，第二多载波模块 92中包括 k个分别与各基带信号对应的中频 单元。假设第一多载波模块 91中的第一基带处理单元 911具备确定各个载波 的跳频频点属于哪个多载波模块的能力，第一基带处理单元 911可以根据帧 号的变化提前获取接下来时隙上需要接收数据的频点， 如果第一基带处理 单元 911发现该频点属于第二多载波模块 92的接收频率范围（例如，待接收 的数据的频点为 g2, g2位于 gl和 gj之间）， 则将对应的接收频点及解调参数 通过第一基带处理单元 911和第二基带处理单元 921之间的高速总线通知给 第二多载波模块 92, 第二多载波模块 92接收到待接收的数据对应的跳频频 点等信息后， 通过调节自身中频单元的数控振荡器 NC0实现接收射频跳 频， 以及对接收到的数据进行 ADC釆样和数字下变频等上行数据处理。 之 后， 若预先配置的该接收数据属于的模块为第一多载波模块 91 , 即后续的 处理， 例如基带处理都设置在第一多载波模块 91中， 则第二多载波模块 92 将处理后的上行数据通过第二基带处理单元 921和第一基带处理单元 911之 间的高速总线发送给第一多载波模块 91 , 由第一多载波模块 91完成后续的 载波上行数据处理。 通过两个多载波模块的联合， 可以实现频点范围为 fl~gj的上行跳频， 由于 gj-fl>Y, 实现了超过单个多载波模块频点范围（Y ) 的上行跳频处理， 使上行跳频的适用范围更广。
或者， 类似于下行， 在物理上也可以有多个中频单元， 实现上行基带 跳频。
需要说明的是， 尽管本实施例中只描述了两个多载波模块， 本领域技 术人员不难明白， 本实施例也同样适用于三个或更多个多载波模块。 本实 施例通过多个多载波模块之间的连接， 可以由适合的多载波模块处理对应 的频点， 实现频点范围的扩大， 扩展跳频的适用场景。
本领实施提供的多载波模块 （如图 8或图 9所示） 可以应用于多载波基 站， 该多载波基站下行跳频或上行跳频的频点范围能够超出单个多载波模 块下行跳频或上行跳频频点范围， 扩展了跳频的适用场景。
图 7对应的第七实施例从一个多载波模块 （执行确定功能的多载波模 块） 的基带处理单元角度进行了描述。 对多载波基站来讲， 本发明还提供 了一个基站跳频方法的实施例， 可以包括如下步骤： 确定待收发数据的跳 频频点； 确定该跳频频点属于的多载波模块； 通过所述跳频频点属于的多 载波模块在所述跳频频点上对所述待收发数据进行收发处理。
其中在下行方向上，
多载波基站确定待发送数据的跳频频点，所述待发送数据为基带数据； 多载波基站确定该跳频频点属于的多载波模块；
若所述待发送数据对应的基带处理单元属于一个多载波模块， 而该跳 频频点属于的多载波模块是另一个多载波模块， 多载波基站将所述待发送 数据从所述一个多载波模块传送到所述另一个多载波模块， 由所述另一个 多载波模块在该跳频频点上将调制后的待发送数据发射出去。
在上行方向上，
多载波基站确定待接收数据的跳频频点，所述待接收数据为射频数据； 多载波基站确定该跳频频点属于的一个多载波模块；
多载波基站通过该跳频频点属于的一个多载波模块接收待接收数据， 所述待接收数据为射频数据；
多载波基站对所述待接收数据进行处理， 得到基带数据；
若所述基带数据对应的多载波模块为另一个多载波模块， 多载波基站 将所述基带数据从所述一个多载波模块传送给所述另一个多载波模块； 由 所述另一个多载波模块进行基带处理。
本领域普通技术人员可以理解： 实现上述方法实施例的全部或部分步 骤可以通过程序指令相关的硬件来完成， 前述的程序可以存储于一计算机 可读取存储介质中， 该程序在执行时， 执行包括上述方法实施例的步骤； 而前述的存储介质包括： ROM、 RAM, 磁碟或者光盘等各种可以存储程序 代码的介质。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案而非对其进 行限制， 尽管参照较佳实施例对本发明进行了详细的说明， 本领域的普通技 术人员应当理解： 其依然可以对本发明的技术方案进行修改或者等同替换， 而这些修改或者等同替换亦不能使修改后的技术方案脱离本发明技术方案的 ^"神和范围。
