Description
一种获得合并增益的方法和基站 技术领域
本发明实施例涉及通信领域, 尤其涉及一种获得合并增益的方法和基站。 背景技术
随着移动通信的不断演进, 通用移动通信系统(UMTS, Universal Mobile Telecommunications System )已经或即将成为移动通信的主流标准。与此同时, 智能手机的不断普及对数据通讯的需求也在迅猛增长。在频谱带宽有限的情况 下, 不断挖掘频谱利用效率是业界的共同追求。
在 UMTS中存在更软切换、 软切换和硬切换等切换方式, 由于基站间数据 交互存在一定难度, 而且单个芯片容量总是有限, 因此并不是所有的同频小区 都能实现更软切换。 一般只选择在邻近的少数几个同频小区之间进行更软切 换, 其余的小区之间采用软切换或硬切换。
现有技术中, 对于同一个基站(Node B )支持的所有同频小区进行小区组 的划分, 即, 将载波频率相同的小区划分成一组, 这样的一组小区可以称作同 频小区组。在载波频率相同的一组小区内支持更软切换, 同频小区组之间支持 软切换。 例如, 小区 0和小区 1为一个同频小区组, 小区 2和小区 3为另一个同频 小区组。 小区 0和小区 1之间或小区 2和小区 3之间支持更软切换, 而小区 0和小 区 2之间、 小区 0和小区 3之间、 小区 1和小区 2之间或者小区 1和小区 3之间支持 软切换。对于支持更软切换的小区, 所有天线接收的数据都一起输送至与该小 区相连的所有基带处理芯片, 而基带处理芯片之间不进行数据交换。
由于单个基带处理芯片的容量或处理能力有限, 因此, 即使在一个基站内 部也可能出现多个同频小区组。换言之,在基站内部出现多个同频小区组的情 况下, 同频小区组的小区之间通常采用软切换, 而软切换时数据的合并是一种 选择性合并, 性能相对较差。

本发明实施例提供一种获得合并增益的方法和基站, 以提高数据解调性 能。
请参阅附图 1 , 是本发明实施例提供的一种获得合并增益的方法流程示意 图, 主要包括步骤:
S101 ,主基带处理芯片接收上行数据和至少一个辅基带处理芯片对所述至 少一个辅基带处理芯片接收的上行数据进行最大比合并后发送至所述主基带 处理芯片的数据,所述上行数据由用户设备同时向所述主基带处理芯片和所述 辅基带处理芯片发送;
在本发明提供的实施例中,主基带处理芯片或辅基带处理芯片可以是定制 化的, 也可以是通用的, 例如, 可以是特定用途集成电路(ASIC, Application Specific Integrated Circuit )„在本发明提供的一个实施例中,主基带处理芯片是 用户设备 ( User Equipment, UE )所有无线链路 ( Radio Link, RL )所在的所 有基带芯片中的一个, 可以是小区中主服务基站中的处理芯片,辅基带处理芯
片是 UE所有无线链路所在的所有基带芯片中除主基带处理芯片之外的处理芯 片, 可以是小区中辅服务基站中的处理芯片。 所谓主服务基站和辅服务基站, 是为了最大限度地提高数据解调性能而在小区中设立的两类基站, 一般地, 小区中只有一个主服务基站, 但辅服务基站可以不限于一个。 主服务基站和 辅服务基站会接收同一 UE发送的同一数据, 而且均会对这些数据进行解调解 码, 所不同的是, 主服务基站会通过与辅服务基站进行信息的交互(例如, 辅 服务基站通过 lub接口向主服务基站发送对数似然比软值信息),通过从辅服务 基站得到的信息并结合自身对 UE发送的数据的处理而提高数据解调性能, 但 辅服务基站之间一般不会进行信息的交互。 因此, 从拓朴上来看, 主服务基站 与辅服务基站可以是一种星形连接, 即, 主服务基站与所有辅服务基站之间有 连接关系, 但辅服务基站之间不存在连接关系。 在本发明提供的其他实施例中,主基带处理芯片和辅基带处理芯片也可以 处于同一个基站(NodeB ) 中, 此处的基站可以是一个物理基站实体, 也可以 是一个逻辑基站。所谓逻辑基站,是指包含一个物理基站或多个物理基站的逻 辑体, 这些逻辑体之间可以通过数据交换实现数据的更软合并。
S102, 主基带处理芯片对所述主基带处理芯片接收的数据进行最大比合 并。
主基带处理芯片在收到用户设备发送至该主基带处理芯片的上行数据后, 首先进行解调, 然后对解调后的数据进行最大比合并。 如前所述, 由于用户设 备同时向主基带处理芯片和所有辅基带处理芯片发送上行数据, 因此,辅基带 处理芯片也可以对其自身接收的上行数据进行最大比合并后发送至主基带处 理芯片。主基带处理芯片接收至少一个辅基带处理芯片对接收到的上行数据进 行最大比合并后的数据后,将对该主基带处理芯片自身接收的上行数据进行最 大比合并后的数据和至少一个辅基带处理芯片对接收到的上行数据进行最大 比合并后的数据再次进行最大比合并,之后, 主基带处理芯片对所述再次进行
最大比合并后所得数据进行译码以及判决等处理。在本发明实施例中,译码也 可在进行最大比合并之前处理, 本实施例是在对数据进行最大比合并之后进 行。
在本发明提供的实施例中,主基带处理芯片或辅基带处理芯片能够对解调 后的数据进行最大比合并主要是基于这样一个事实, 即,一个传输符号由于多 径传播, 其能量被分散到不同的传输路径上, 并且这些能量通过这些路径到达 接收端的时间也不相同。所谓最大比合并是指先明确一个传输符号的不同路径 (例如, 本发明实施例中一个传输符号经过所有辅服务基站), 再统计这些不 同路径上的能量的总和,计算每条路径在总能量中所占的比例, 然后将这个比 例乘以该条路径在传输这个传输符号时刻的信噪比( Signal Noise Ratio, SNR ), 最后将这些乘积按照路径数累加起来的结果即为最大比合并的结果。
主基带处理芯片可以将经过译码后所得数据进行干扰抵消 ( IC , Interference Cancellation ), 或者, 将经过译码后所得数据发送至所有所述辅基 带处理芯片, 以提供给所有辅基带处理芯片由其决定是否进行 IC的处理。在本 发明实施例中, 干扰抵消是指对解调或译码后的信号(数据 )进行重构, 将重 构后的信号 (数据)从天线数据中抵消掉, 以减少该用户对其它用户的干扰。 需要说明的是, 并不是对所有的用户都会进行干扰抵消,对于某用户是否进行 干扰抵消由资源管理模块决定, 例如,在主基带处理芯片中该用户是速率最高 的用户, 则进行干扰抵消。 然而, 在辅基带处理芯片中, 若该用户速率不是最 高的, 而且比该用户更高速率的用户占用了所有的干扰抵消资源, 则该用户在 辅基带处理芯片中可以不进行干扰抵消。
主基带处理芯片和辅基带处理芯片之间进行数据交互前可以先进行消息 通知, 使得主基带处理芯片和辅基带处理芯片之间能够正常通信。 具体地, 当 无线网络控制器(RNC, Radio Network Controller )对指定用户设备(即同时
向主基带处理芯片和辅基带处理芯片发送上行数据的用户设备, 下同) 进行 RL建立、重配和删除等操作时, RNC通知主控模块进行相应的操作, 即, RNC 对指定 UE进行 RL建立、 重配和删除等操作时, RNC通知主控模块该 RNC对指 定用户设备进行 RL建立、 重配和删除等操作。 主控模块收到这一通知后, 向 主基带处理芯片转发,主基带处理芯片接收由主控模块转发的 RNC对指定用户 设备进行 RL建立、 重配和删除等操作的通知。 在本发明实施例中, 主控模块 可以是一个逻辑概念, 例如, 主控模块可以是一个物理实体, 也可以是多个物 理实体映射在不同的物理 NodeB、 RNC等。 RNC对主控模块的通知方式可以是 显式的信令, 也可以是隐式的通知, 例如, 对于显式的信令这种通知方式, 所 有信令发送至主控模块后由主控模块对信令进行解析,分发到主基带处理芯片 和辅基带处理芯片, 而隐式的通知方式, 可以是直接将信令传递至主基带处理 芯片或辅基带处理芯片, 由主基带处理芯片或辅基带处理芯片解析信令, 然后 主基带处理芯片或辅基带处理芯片将解析之后的信令通知主控模块;主控模块 也可以根据需要通知所有或部分主基带处理芯片 /辅基带处理芯片相应的主基 带处理芯片 /辅基带处理芯片的地址信息, 主基带处理芯片 /辅基带处理芯片接 收由主控模块通知的主基带处理芯片或辅基带处理芯片的地址信息。例如, 当 主基带处理芯片发生变化时,通知所有的辅基带处理芯片, 当辅基带处理芯片 发生变化时通知主基带处理芯片, 此处的通知不限于上述方式,也可以采用广 播、 组播等方式。
从上述本发明实施例可知,由于主基带处理芯片先是对用户设备发送至所 述主基带处理芯片的上行数据进行最大比合并, 然后,将此次最大比合并所得 数据与至少一个辅基带处理芯片对所述至少一个辅基带处理芯片接收的上行 数据进行最大比合并所得数据一起, 再次进行最大比合并, 因此, 相对于软切 换时的选择性合并, 本发明实施例提供的方法可以获得较好的增益,提高数据
解调性能; 另一方面, 主基带处理芯片接收辅基带处理芯片对上行数据进行最 大比合并后的数据, 这种通过片间交互的方式可以获得更软合并增益, 减少用 户的重传次数, 提升小区边缘用户的速率, 降低掉话率, 提升用户体验。
请参阅附图 2 ,本发明另一实施例提供的获得合并增益的方法流程示意图, 主要包括步骤:
5201 , 主基带处理芯片对上行数据进行译码。
译码 (或解码 )是编码的逆过程, 目的是还原或获得编码前的上行数据。 在本发明实施例中,所述上行数据是由用户设备同时向辅基带处理芯片和所述 主基带处理芯片发送的数据, 而主基带处理芯片、辅基带处理芯片分别与附图 1所述实施例中的主基带处理芯片、 辅基带处理芯片类似, 此处不做赞述, 可 参阅前述实施例。
5202,若主基带处理芯片译码错误且所有辅基带处理芯片对所述辅基带处 理芯片接收的上行数据译码错误,则所述主基带处理芯片接收至少一个辅基带 处理芯片对所述至少一个辅基带处理芯片接收的上行数据进行最大比合并后 的数据。
显然, 对于译码错误的数据进行最大比合并没有意义, 并且, 如前所述, 译码可在数据进行了最大比合并(无论是初次进行最大比合并还是再次进行最 大比合并)之后进行。 因此, 在本实施例中, 若主基带处理芯片译码错误且所 有辅基带处理芯片对所述辅基带处理芯片接收的上行数据译码错误,则所述主 基带处理芯片接收至少一个辅基带处理芯片对所述至少一个辅基带处理芯片 接收的上行数据进行最大比合并后的数据,以便在进行了最大比合并之后再进 行译码等处理。
5203 , 主基带处理芯片对所述主基带处理芯片接收的数据进行最大比合 并。
在本实施例中, 若主基带处理芯片对其接收的上行数据译码正确, 则主基 带处理芯片可以对所述译码正确的数据进行最大比合并, 或者, 若所有辅基带 处理芯片中至少有一个辅基带处理芯片对其接收的上行数据译码正确,则主基 带处理芯片可以接收至少一个辅基带处理芯片对上行数据进行正确译码后的 数据, 即,接收来自于其中一个辅基带处理芯片对其接收的上行数据进行正确 译码后的数据、来自于所有辅基带处理芯片对其接收的上行数据进行正确译码 后的数据, 或者根据预设的条件,选择接收部分辅基带处理芯片对该部分辅基 带处理芯片接收的上行数据进行正确译码后的数据。具体地, 这些数据可以是 软符号经星座图解映射和译码后得到的软比特 /硬比特, 其中, 软符号是指在 星座图解映射之前的一个符号, 可能包含一个比特, 也可能包含多个比特, 具 体包含的比特数和调制方式有关, 例如, BPSK调制方式的符号包含 1个比特, QPSK调制方式的符号比特包含 2个, 而 16QAM调制方式的符号包含 3个比特, 等等。
若所述主基带处理芯片译码错误且所有所述辅基带处理芯片对所述辅基 带处理芯片接收的上行数据译码错误,则主基带处理芯片对接收的数据进行最 大比合并包括:
主基带处理芯片对译码错误之前接收的上行数据(用户设备发送至所述主 基带处理芯片的上行数据 )进行最大比合并。 由于用户设备同时向主基带处理 芯片和所有辅基带处理芯片发送上行数据,辅基带处理芯片可以对辅基带处理 芯片在译码错误前接收的上行数据进行最大比合并后发送至主基带处理芯片。 主基带处理芯片接收到这部分数据后,将对该主基带处理芯片在译码错误之前 接收的上行数据进行最大比合并后的数据和至少一个辅基带处理芯片在译码 错误前接收的上行数据进行最大比合并后的数据再次进行最大比合并, 之后, 主基带处理芯片对所述再次进行最大比合并后所得数据进行译码以及判决等
处理。
主基带处理芯片可以将经过译码后所得数据进行干扰抵消, 或者,将经过 译码后所得数据发送至所有所述辅基带处理芯片,以提供给所有辅基带处理芯 片由其决定是否进行干扰抵消的处理。在本发明实施例中, 干扰抵消是指对解 调或译码后的信号(数据 )进行重构, 将重构后的信号(数据 )从天线数据中 抵消掉, 以减少该用户对其它用户的干扰。 需要说明的是, 并不是对所有的用 户都会进行干扰抵消,对于某用户是否进行干扰抵消由资源管理模块决定, 例 如, 在主基带处理芯片中该用户是速率最高的用户, 则进行干扰抵消。 然而, 在辅基带处理芯片中, 若该用户速率不是最高的, 而且比该用户更高速率的用 户占用了所有的干扰氐消所用资源,则该用户在辅基带处理芯片中可以不进行 干扰抵消。
与前述实施例类似,主基带处理芯片和辅基带处理芯片之间进行数据交互 前可以先进行消息通知,使得主基带处理芯片和辅基带处理芯片之间能够正常 通信。 具体地, 当无线网络控制器(RNC, Radio Network Controller )对指定 用户设备进行 RL建立、 重配和删除等操作时, RNC通知主控模块进行相应的 操作, 即, RNC对指定用户设备进行 RL建立、 重配和删除等操作时, RNC通 知主控模块该 RNC对指定用户设备进行 RL建立、 重配和删除等操作。 主控模 块收到这一通知后, 向主基带处理芯片转发, 主基带处理芯片接收由主控模块 转发的 RNC对指定用户设备进行 RL建立、 重配和删除等操作的通知。 在本发 明实施例中, 主控模块可以是一个逻辑概念, 例如, 主控模块可以是一个物理 实体, 也可以是多个物理实体映射在不同的物理 NodeB、 RNC等。 RNC对主控 模块的通知方式可以是显式的信令, 也可以是隐式的通知, 例如, 对于显式的 信令这种通知方式, 所有信令发送至主控模块后由主控模块对信令进行解析, 分发到主基带处理芯片和辅基带处理芯片, 而隐式的通知方式, 可以是直接将
信令传递至主基带处理芯片或辅基带处理芯片,由主基带处理芯片或辅基带处 理芯片解析信令,然后主基带处理芯片或辅基带处理芯片将解析之后的信令通 知主控模块; 主控模块也可以根据需要通知所有或部分主基带处理芯片 /辅基 带处理芯片相应的主基带处理芯片 /辅基带处理芯片的地址信息, 主基带处理 芯片 /辅基带处理芯片接收由主控模块通知的主基带处理芯片或辅基带处理芯 片的地址信息。 例如, 当主基带处理芯片发生变化时, 通知所有的辅基带处理 芯片, 当辅基带处理芯片发生变化时通知主基带处理芯片, 此处的通知不限于 上述方式, 也可以采用广播、 组播等方式。
从上述本发明实施例可知,由于主基带处理芯片先是对用户设备发送至所 述主基带处理芯片的上行数据进行译码,在主基带处理芯片译码错误且所有辅 基带处理芯片对所述辅基带处理芯片接收的上行数据译码错误时,将主基带处 理芯片对用户设备发送至所述主基带处理芯片的上行数据进行最大比合并后 所得数据与至少一个辅基带处理芯片对所述至少一个辅基带处理芯片接收的 上行数据进行最大比合并所得数据一起, 再次进行最大比合并, 因此, 相对于 软切换时的选择性合并, 本发明实施例提供的方法可以获得较好的增益,提高 数据解调性能; 另一方面, 主基带处理芯片接收辅基带处理芯片对上行数据进 行最大比合并后的数据, 这种通过片间交互的方式可以获得更软合并增益, 减 少用户的重传次数, 提升小区边缘用户的速率, 降低掉话率, 提升用户体验。
请参阅附图 3 , 基于本说明书前述实施例的实施, 相对应的, 附图 3是本发 明另一实施例提供的获得合并增益的方法流程示意图, 该方法主要包括步骤:
5301 , 辅基带处理芯片对所述辅基带处理芯片接收的上行数据进行译码。 在本实施例中,所述上行数据是用户设备同时向主基带处理芯片和所述辅 基带处理芯片发送的数据。
5302,若辅基带处理芯片译码错误,则该辅基带处理芯片对辅基带处理芯
片接收的上行数据进行最大比合并。
在本发明提供的实施例中,辅基带处理芯片能够对解调后的数据进行最大 比合并主要是基于这样一个事实, 即, 一个传输符号由于多径传播, 其能量被 分散到不同的传输路径上,并且这些能量通过这些路径到达接收端的时间也不 相同。 所谓最大比合并是指先明确一个传输符号的不同路径(例如, 本发明实 施例中一个传输符号经过所有辅服务基站 ), 再统计这些不同路径上的能量的 总和,计算每条路径在总能量中所占的比例, 然后将这个比例乘以该条路径在 传输这个传输符号时刻的 SNR,最后将这些乘积按照路径数累加起来的结果即 为最大比合并的结果。
S303 ,辅基带处理芯片将进行最大比合并后所得数据发送至所述主基带处 理芯片。
辅基带处理芯片将进行最大比合并后所得数据发送至主基带处理芯片的 目的在于,使主基带处理芯片对接收到的数据进行最大比合并, 主基带处理芯 片对接收到的数据进行最大比合并的原理与辅基带处理芯片将进行最大比合 并相同。主基带处理芯片对接收到的数据进行最大比合并后, 进行译码和判决 等处理, 可以将译码所得数据发送至辅基带处理芯片。
辅基带处理芯片对接收到的主基带处理芯片译码所得数据可进行干扰抵 消。 所谓干扰抵消, 是指对解调或译码后的信号(数据)进行重构, 将重构后 的信号(数据)从天线数据中抵消掉, 以减少该用户对其它用户的干扰。 需要 说明的是, 并不是对所有的用户都会进行干扰抵消,对于某用户是否进行干扰 抵消由资源管理模块决定, 例如,在主基带处理芯片中该用户是速率最高的用 户, 则进行干扰抵消。 然而,在辅基带处理芯片中,若该用户速率不是最高的, 而且比该用户更高速率的用户占用了所有的干扰抵消所用资源,则该用户在辅 基带处理芯片中可以不进行干扰抵消。

辅基带处理芯片对接收到的主基带处理芯片译码所得数据可进行干扰抵 消。 所谓干扰抵消, 是指对解调或译码后的信号(数据)进行重构, 将重构后 的信号(数据)从天线数据中抵消掉, 以减少该用户对其它用户的干扰。 需要 说明的是, 并不是对所有的用户都会进行干扰抵消,对于某用户是否进行干扰 抵消由资源管理模块决定, 例如,在主基带处理芯片中该用户是速率最高的用 户, 则进行干扰抵消。 然而,在辅基带处理芯片中,若该用户速率不是最高的, 而且比该用户更高速率的用户占用了所有的干扰抵消所用资源,则该用户在辅 基带处理芯片中可以不进行干扰抵消。

参考上述方法实施例的实现,请参阅附图 7, 附图 7是本发明实施例提供的 获得合并增益的基站逻辑结构示意图,所述获得合并增益的基站可用于实现前 述实施例所揭示的获得合并增益的方法。 为了便于说明,仅仅示出了与本发明 实施例相关的部分, 其中包含的功能模块 /单元可以是软件模块 /单元、 硬件模 块 /单元或软硬件相结合模块 /单元(本说明书提供的各个实施例都可应用这一 描述原则)。 图 7示例的获得合并增益的基站包括第一基带处理芯片, 可以是前 述方法实施例的主基带处理芯片, 该第一基带处理芯片包括接收模块 701和最 大比合并模块 702, 其中:
接收模块 701 , 用于接收上行数据和至少一个第二基带处理芯片对所述至
少一个第二基带处理芯片接收的上行数据进行最大比合并后发送至所述第一 基带处理芯片的数据,所述上行数据由用户设备同时向所述第一基带处理芯片 和所述第二基带处理芯片发送。本实施例中, 第二基带处理芯片可以是前述实 施例中的辅基带处理芯片;
最大比合并模块 702, 用于对所述接收模块 701接收的数据进行最大比合 并。
需要说明的是, 以上获得合并增益的基站的实施方式中,各功能模块的划 分仅是举例说明, 实际应用中可以根据需要, 例如相应硬件的配置要求或者软 件的实现的便利考虑, 而将上述功能分配由不同的功能模块完成, 即将所述获 得合并增益的基站的内部结构划分成不同的功能模块,以完成以上描述的全部 或者部分功能。 而且, 实际应用中, 本实施例中的相应的功能模块可以是由相 应的硬件实现, 也可以由相应的硬件执行相应的软件完成, 例如, 前述的接收 模块,可以是具有执行前述接收上行数据和至少一个第二基带处理芯片对所述 至少一个第二基带处理芯片接收的上行数据进行最大比合并后发送至所述第 一基带处理芯片的数据的硬件, 例如接收器,也可以是能够执行相应计算机程 序从而完成前述功能的一般处理器或者其他硬件设备;再如前述的最大比合并 模块, 可以是具有执行前述对接收模块(或接收器 )接收的数据进行最大比合 并功能的硬件, 例如最大比合并器,也可以是能够执行相应计算机程序从而完 成前述功能的一般处理器或者其他硬件设备(本说明书提供的各个实施例都可 应用上述描述原则)。
在附图 7示例的获得合并增益的基站中, 第一基带处理芯片或第二基带处 理芯片可以是定制化的, 也可以是通用的, 例如, 可以是特定用途集成电路 ( ASIC, Application Specific Integrated Circuit )。 在本发明提供的一个实施例 中, 第一基带处理芯片是用户设备所有无线链路所在的所有基带芯片中的一 个, 可以是小区中主服务基站中的处理芯片, 第二基带处理芯片是用户设备所 有无线链路所在的所有基带芯片中除第一基带处理芯片之外的处理芯片,可以
是小区中辅服务基站中的处理芯片。所谓主服务基站和辅服务基站,是为了最 大限度地提高数据解调性能而在小区中设立的两类基站, 一般地, 小区中只 有一个主服务基站, 但辅服务基站不限于一个。 主服务基站和辅服务基站会 接收同一 UE发送的同一数据, 而且均会对这些数据进行解调解码, 所不同的 是, 主服务基站会通过与辅服务基站进行信息的交互(例如, 辅服务基站通过 Iub接口向主服务基站发送对数似然比软值信息),通过从辅服务基站得到的信 息并结合自身对用户设备发送的数据的处理而提高数据解调性能,但辅服务基 站之间一般不会进行信息的交互。 因此, 从拓朴上来看, 主服务基站与辅服务 基站可以是一种星形连接,即,主服务基站与所有辅服务基站之间有连接关系, 但辅服务基站之间不存在连接关系。
在附图 7示例的获得合并增益的基站中, 第一基带处理芯片和第二基带处 理芯片也可以处于同一个基站(NodeB ) 中, 此处的基站可以是一个物理基站 实体, 也可以是一个逻辑基站。 所谓逻辑基站, 是指包含一个物理基站或多个 物理基站的逻辑体, 这些逻辑体之间可以通过数据交换实现数据的更软合并。
附图 7示例的最大比合并模块 702可以包括第一合并单元 801和第二合并单 元 802, 如附图 8所示本发明另一实施例提供的获得合并增益的基站, 其中: 第一合并单元 801 , 用于对用户设备发送至所述第一基带处理芯片的上行 数据进行最大比合并;
第二合并单元 802, 用于对第一部分数据和第二部分数据再次进行最大比 合并, 所述第一部分数据为所述第一合并单元 801对用户设备发送至所述接收 模块 701的上行数据进行最大比合并所得数据, 所述第二部分数据为所述至少 一个第二基带处理芯片对所述至少一个第二基带处理芯片接收的上行数据进 行最大比合并所得数据,所述第二部分数据由所述至少一个第二基带处理芯片 发送至第一基带处理芯片的接收模块 701。
具体地, 第一基带处理芯片的接收模块 701在收到用户设备发送至该第一 基带处理芯片的上行数据后, 第一基带处理芯片首先进行解调, 然后第一合并 单元 801对解调后的数据进行最大比合并。 如前所述, 由于用户设备同时向第 一基带处理芯片和所有第二基带处理芯片发送上行数据, 因此, 第二基带处理 芯片也可以对其自身接收的上行数据进行最大比合并后发送至第一基带处理 芯片。 第一基带处理芯片的接收模块 701接收至少一个第二基带处理芯片对接 收到的上行数据进行最大比合并后的数据后, 第二合并单元 802将对该第一基 带处理芯片的接收模块 701接收的上行数据进行最大比合并后的数据和至少一 个第二基带处理芯片对接收到的上行数据进行最大比合并后的数据再次进行 最大比合并,之后, 第一基带处理芯片对所述再次进行最大比合并后所得数据 进行译码以及判决等处理。在本发明实施例中,译码也可在进行最大比合并之 前处理, 本实施例是在对数据进行最大比合并之后进行。
附图 7或附图 8示例的第一基带处理芯片还可以包括译码模块 901和发送模 块 902, 如附图 9所示本发明另一实施例提供的获得合并增益的基站, 其中: 译码模块 901 ,用于对所述第二合并单元 802再次进行最大比合并后所得数 据进行译码;

附图 9示例的第一基带处理芯片还可以包括干扰抵消模块 1001 , 如附图 10 所示本发明另一实施例提供的获得合并增益的基站。干扰抵消模块 1001用于对 所述译码模块 901译码后所得数据进行干扰抵消 ( IC , Interference Cancellation )。
在附图 10示例的获得合并增益的基站中,所谓干扰抵消是指对解调或译码 后的信号 (数据)进行重构, 将重构后的信号 (数据)从天线数据中抵消掉,
以减少该用户对其它用户的干扰。 需要说明的是, 并不是对所有的用户都会进 行干扰抵消, 对于某用户是否进行干扰抵消由资源管理模块决定, 例如, 在第 一基带处理芯片中该用户是速率最高的用户, 则进行干扰抵消。 然而, 在第二 基带处理芯片中,若该用户速率不是最高的, 而且比该用户更高速率的用户占 用了所有的干扰抵消资源,则该用户在第二基带处理芯片中可以不进行干扰抵 消。
第一基带处理芯片和第二基带处理芯片之间进行数据交互前可以先进行 消息通知,使得第一基带处理芯片和第二基带处理芯片之间能够正常通信。具 体地, 当无线网络控制器(RNC, Radio Network Controller )对指定用户设备 进行 RL建立、 重配和删除等操作时, RNC通知主控模块进行相应的操作, 即, RNC对指定用户设备进行 RL建立、 重配和删除等操作时, RNC通知主控模块 该 RNC对指定用户设备进行 RL建立、 重配和删除等操作。 因此, 附图 7至附图 10任一示例的第一基带处理芯片还可以包括通知接收模块 1101或者地址信息 接收模块 1102, 如附图 11所示本发明另一实施例提供的获得合并增益的基站, 其中:

地址信息接收模块 1102,用于接收由主控模块通知的第一基带处理芯片或 第二基带处理芯片的地址信息。
具体地, 主控模块收到无线网络控制器对指定用户设备进行操作的通知 后, 向第一基带处理芯片转发, 第一基带处理芯片的通知接收模块 1101接收由 主控模块转发的 RNC对指定用户设备进行 RL建立、重配和删除等操作的通知。 在本实施例中, 主控模块可以是一个逻辑概念, 例如, 主控模块可以是一个物 理实体, 也可以是多个物理实体映射在不同的物理 NodeB、 RNC等。 RNC对主
控模块的通知方式可以是显式的信令, 也可以是隐式的通知, 例如, 对于显式 的信令这种通知方式, 所有信令发送至主控模块后由主控模块对信令进行解 析, 分发到第一基带处理芯片和第二基带处理芯片, 而隐式的通知方式, 可以 是直接将信令传递至第一基带处理芯片或第二基带处理芯片,由第一基带处理 芯片或第二基带处理芯片解析信令,然后第一基带处理芯片或第二基带处理芯 片将解析之后的信令通知主控模块;主控模块也可以根据需要通知所有或部分 第一基带处理芯片 /第二基带处理芯片相应的第一基带处理芯片 /第二基带处理 芯片的地址信息, 第一基带处理芯片的地址信息接收模块 1102/第二基带处理 芯片接收由主控模块通知的第一基带处理芯片或第二基带处理芯片的地址信 息。 例如, 当第一基带处理芯片发生变化时, 通知所有的第二基带处理芯片, 当第二基带处理芯片发生变化时通知第一基带处理芯片,此处的通知不限于上 述方式, 也可以采用广播、 组播等方式。
需要说明的是, 在附图 7至附图 11任意一个示例的获得增益的基站中, 第 一基带处理芯片和第二基带处理芯片可以处于相同的物理基站或逻辑基站;或 者, 第一基带处理芯片和第二基带处理芯片分别处于不同的物理基站, 例如, 第一基带处理芯片处于主服务基站,第二基带处理芯片处于辅服务基站;或者, 第一基带处理芯片和第二基带处理芯片分别处于不同的逻辑基站。

在附图 12示例的获得增益的基站中,第一基带处理芯片或第二基带处理芯 片可以是定制化的,也可以是通用的,例如,可以是特定用途集成电路(ASIC, Application Specific Integrated Circuit )„在本发明提供的一个实施例中,第一基 带处理芯片是用户设备所有无线链路(Radio Link, RL )所在的所有基带芯片 中的一个, 可以是小区中主服务基站中的处理芯片, 第二基带处理芯片是用户 设备所有无线链路所在的所有基带芯片中除第一基带处理芯片之外的处理芯 片, 可以是小区中辅服务基站中的处理芯片。 所谓主服务基站和辅服务基站,
是为了最大限度地提高数据解调性能而在小区中设立的两类基站, 一般地, 小区中只有一个主服务基站, 但辅服务基站不限于一个。 主服务基站和辅服 务基站会接收同一用户设备发送的同一数据,而且均会对这些数据进行解调解 码, 所不同的是, 主服务基站会通过与辅服务基站进行信息的交互(例如, 辅 服务基站通过 lub接口向主服务基站发送对数似然比软值信息),通过从辅服务 基站得到的信息并结合自身对用户设备发送的数据的处理而提高数据解调性 能, 但辅服务基站之间一般不会进行信息的交互。 因此, 从拓朴上来看, 主服 务基站与辅服务基站可以是一种星形连接, 即, 主服务基站与所有辅服务基站 之间有连接关系, 但辅服务基站之间不存在连接关系。
在附图 12示例的获得增益的基站中,第一基带处理芯片和第二基带处理芯 片也可以处于同一个基站(NodeB )中,此处的基站可以是一个物理基站实体, 也可以是一个逻辑基站。所谓逻辑基站,是指包含一个物理基站或多个物理基 站的逻辑体, 这些逻辑体之间可以通过数据交换实现数据的更软合并。
