图 1为本发明信道状态信息 CSI进程配置的方法一个实施例的流 程图, 如图 1所示, 该信道状态信息 CSI进程配置的方法可以包括: 步骤 101 , 基站获取用户设备 UE ( User Equipment, 用户设备) 的信道状态信息 CSI进程处理能力。
其中, 用户设备 UE的信道状态信息 CSI进程处理能力可以是预 定义的或所述用户设备 UE上报的。从而,基站获取预存的预定义的用 户设备 UE的信道状态信息 CSI进程处理能力, 或基站接收所述用户 设备 UE上报的所述用户设备 UE的信道状态信息 CSI进程处理能力。
步骤 102 ,基站向所述用户设备 UE发送信道状态信息 CSI进程配 置信息, 以使所述用户设备根据配置的所述信道状态信息 CSI进程测 量信道状态信息 CSI, 所述信道状态信息 CSI进程配置信息中的 X个 信道状态信息 CSI进程信息对应同一个载波, X大于所述用户设备 UE 的信道状态信息 CSI 进程处理能力中所述载波对应的信道状态信息 CSI进程数量。
具体的, 用户设备 UE的信道状态信息 CSI进程处理能力可以为 用户设备 UE最多支持 K个 CC ( Component Carrier, 成员载波) , 以 及用户设备 UE被配置 K个 CC时,用户设备 UE在每一个载波上支持 P个信道状态信息 CSI进程的处理。
可选的, 基站为用户设备 UE配置信道状态信息 CSI进程, 可以 为基站根据所述信道状态信息 CSI进程处理能力为用户设备 UE配置 信道状态信息 CSI进程, 以保证用户设备 UE能够处理基站配置的所 有的信道状态信息 CSI进程。
可选的, 基站为用户设备 UE 配置的一个或多个载波对应信道状 态信息 CSI进程的数量的和, 小于等于用户设备 UE的信道状态信息 CSI进程处理能力中包括的各载波对应的信道状态信息 CSI进程数量 的和。 这样, 基站可以根据用户设备 UE的信道状态信息 CSI进程处 理能力, 在为用户设备 UE配置信道状态信息 CSI进程时, 使用户设 备 UE在支持的多个载波间共享信道状态信息 CSI进程处理能力, 且 保证用户设备 UE能够处理基站配置的所有的信道状态信息 CSI进程。
例如, 用户设备 UE上报信道状态信息 CSI进程处理能力为: 用 户设备 UE最多支持 2个成员载波, 当用户设备 UE被配置了 2个 CC 时, 在每一个 CC上都支持 1个信道状态信息 CSI 进程。 那么用户设 备 UE能够支持的信道状态信息 CSI进程总数最大为 2。 当基站将 CC1 和 CC2 同时配置给用户设备 UE 时, 基站在 CC1 上可以为用户设备 UE配置一个信道状态信息 CSI进程 1 , 在 CC2上也可以为用户设备 UE配置一个信道状态信息 CSI进程 2。 用户设备 UE根据基站配置, 在 CC1上测量信道状态信息 CSI进程 1 , 在 CC2上测量信道状态信息 CSI进程 2 ,并将基站配置的两个信道状态信息 CSI进程的测量结果上 报。 当基站只将 CC1配置给用户设备 UE时, 基站可以在 CC1上为用 户设备 UE配置 2个信道状态信息 CSI进程(大于用户设备 UE上报的 信道状态信息 CSI进程处理能力中一个 CC上支持的 1个信道状态信 息 CSI进程) 。 用户设备 UE根据基站配置, 在 CC1上测量信道状态 信息 CSI进程 1和信道状态信息 CSI进程 2 , 并将基站配置的两个信 道状态信息 CSI进程的测量结果上报。

例如, 当用户设备 UE的信道状态信息 CSI进程处理能力只包括 一种 CC配置下的信道状态信息 CSI进程处理能力时, 如用户设备 UE 被配置 N1个载波时用户设备 UE在每一个载波上支持的信道状态信息 CSI进程处理的数量为 PN1 , 基站可以为用户设备 UE配置 Nl个载波, 其中至少一个 CC上配置的信道状态信息 CSI进程数大于 PN1 , 或者基 站可以为用户设备 UE配置 J ( N1 ) 个载波, 其中至少一个 CC上配 置的信道状态信息 CSI进程数大于 PN1
又例如, 当用户设备 UE的信道状态信息 CSI进程处理能力包括 一种以上 CC配置下的信道状态信息 CSI进程处理能力时, 如用户设 备 UE被配置 N1个载波时用户设备 UE在每一个载波上支持的信道状 态信息 CSI进程处理的数量为 PN1和用户设备 UE被配置 N2个载波时 用户设备 UE在每一个载波上支持的信道状态信息 CSI进程处理的数 量为 PN2 , 基站可以为用户设备 UE配置 N1个载波, 其中至少一个 CC 上配置的信道状态信息 CSI进程数大于 PN1 ,或者基站可以为用户设备 UE配置 J ( KN1且 KN2; 或者 KN1且 J>=N2 )个载波, 其中至少一 个 CC上配置的信道状态信息 CSI进程数为 V, 那么 V可以为满足以 下条件的数值: 大于 PN1 , 或大于 PN2 , 或大于 PN1且大于 PN2
步骤 103 , 基站接收所述用户设备 UE 根据配置的信道状态信息 CSI进程信息反馈的信道状态信息 CSI。
本发明上述实施例中,其中的基站可以根据用户设备 UE的信道状态信 息 CSI进程处理能力,在为用户设备 UE配置的部分载波配置的信道状态信 息 CSI进程超过用户设备 UE的信道状态信息 CSI进程处理能力,从而可以 进行信道状态信息 CSI进程的灵活配置。尤其当实际配置的 CC数小于用户 设备 UE能够支持的最大 CC数时, 在基站和用户设备 UE达成一致, 在用 户设备 UE能够完成基站配置的信道状态信息 CSI进程处理的同时,两侧都 支持将用户设备 UE能够支持的总的信道状态信息 CSI进程处理能力利用起 来, 从而更好的支持 CoMP传输。

可选的, 基站为用户设备 UE配置信道状态信息 CSI进程, 可以 为基站根据所述信道状态信息 CSI进程处理能力为用户设备 UE配置 信道状态信息 CSI进程, 以保证用户设备 UE能够处理基站配置的所 有的信道状态信息 CSI进程。
其中, 可选的, 基站根据用户设备 UE的信道状态信息 CSI进程 处理能力,可以为用户设备 UE配置一个或多个载波对应的信道状态信 息 CSI进程, 其中至少一个载波对应配置的信道状态信息 CSI进程的 数量可以大于用户设备 UE的信道状态信息 CSI进程处理能力中该载 波对应的信道状态信息 CSI进程数量。
可选的, 基站为用户设备 UE 配置的一个或多个载波对应信道状 态信息 CSI进程的数量的和, 小于等于用户设备 UE的信道状态信息 CSI进程处理能力中包括的各载波对应的信道状态信息 CSI进程数量 的和。 这样, 基站可以根据用户设备 UE的信道状态信息 CSI进程处 理能力, 在为用户设备 UE配置信道状态信息 CSI进程时, 使用户设 备 UE在支持的多个载波间共享信道状态信息 CSI进程处理能力, 且 保证用户设备 UE能够处理基站配置的所有的信道状态信息 CSI进程。

例如, 用户设备 UE上报信道状态信息 CSI进程处理能力为: 用 户设备 UE最多支持 2个成员载波, 当用户设备 UE被配置了 2个 CC 时, 在每一个 CC上都支持 1个信道状态信息 CSI 进程。 那么用户设 备 UE能够支持的信道状态信息 CSI进程总数最大为 2。 当基站将 CC1 和 CC2 同时配置给用户设备 UE 时, 基站在 CC1 上可以为用户设备 UE配置一个信道状态信息 CSI进程 1 , 在 CC2上也可以为用户设备 UE配置一个信道状态信息 CSI进程 2。 用户设备 UE根据基站配置, 在 CC1上测量信道状态信息 CSI进程 1 , 在 CC2上测量信道状态信息 CSI进程 2 , 并将两个信道状态信息 CSI进程的测量结果上报。 当基站 只将 CC1配置给用户设备 UE时, 基站可以在 CC1上为用户设备 UE 配置 2个信道状态信息 CSI进程 (大于用户设备 UE上报的信道状态 信息 CSI进程处理能力中一个 CC上支持的 1个信道状态信息 CSI进 程, 小于等于用户设备 UE上报的信道状态信息 CSI进程处理能力用 户设备 UE在所有 CC上支持的总信道状态信息 CSI进程数即 2个信道 状态信息 CSI进程) 。 用户设备 UE根据基站配置, 在 CC1上测量信 道状态信息 CSI进程 1和信道状态信息 CSI进程 2 , 并将两个信道状 态信息 CSI进程的测量结果上报。
又例如, 用户设备 UE上报信道状态信息 CSI进程处理能力为: 用户设备 UE最多支持 2个成员载波, 当用户设备 UE被配置了 2个 CC时, 在每一个 CC上都支持 3个信道状态信息 CSI 进程。 那么当用 户设备 UE被配置了 2个 CC时用户设备 UE能够支持的信道状态信息 CSI进程总数为 6。 当 CC1、 CC2同时被配置给用户设备 UE时, 基站 可以在 CC1上为用户设备 UE配置信道状态信息 CSI进程 {信道状态信 息 CSI1 , 信道状态信息 CSI2 , 信道状态信息 CSI3 } , 在 CC2上为用户 设备 UE配置信道状态信息 CSI进程 {信道状态信息 CSI4 ,信道状态信 息 CSI5 , 信道状态信息 CSI6}。 用户设备 UE根据基站配置, 在 CC1 上测量信道状态信息 CSI 进程 { 信道状态信息 CSI1 , 信道状态信息 CSI2 ,信道状态信息 CSI3 } ,在 CC2上测量信道状态信息 CSI进程 { 信 道状态信息 CSI4 , 信道状态信息 CSI5 , 信道状态信息 CSI6} , 并将 6 个信道状态信息 CSI进程的测量结果上报。 当基站只将 CC1配置给用 户设备 UE时,基站可以在 CC1上配置 6个信道状态信息 CSI进程(大 于用户设备 UE上报的信道状态信息 CSI进程处理能力中 CC1上支持 的 3个信道状态信息 CSI进程, 小于等于用户设备 UE上报的信道状 态信息 CSI进程处理能力用户设备 UE在所有 CC上支持的总信道状态 信息 CSI进程数即 6个信道状态信息 CSI进程 ) 。 用户设备 UE根据 基站配置,在 CC1上测量信道状态信息 CSI进程 { 信道状态信息 CSI1, 信道状态信息 CSI2, 信道状态信息 CSI3, 信道状态信息 CSI4, 信道 状态信息 CSI5, 信道状态信息 CSI6}, 并将 6个信道状态信息 CSI进 程的测量结果上报。
