Description

一种上行功率控制方法、 系统、 设备及计算机存储介质 技术领域
本发明涉及通信技术， 具体涉及一种上行功率控制方法、 系统、 设备 及计算机存储介质。 背景技术
图 1为现有技术中长期演进（ LTE， Long Term Evolution ) 系统时分双 工 （ TDD， Time Division Duplex )模式的帧结构示意图， 所述帧结构又称 为第二类帧结构 （frame structure type 2 )。 在所述帧结构中， 一个 10ms的 无线帧被分成两个半帧， 每个半帧的长度为 5ms， 包含 5个长度为 1ms的 子帧。 表 1 为上下行配置示意表， 每个子帧的作用如表 1 所示， 其中， D 表示子帧用于下行传输， U表示子帧用于上行传输， S表示特殊子帧且包含 三个特殊时隙， 即下行导频时隙 （DwPTS， Downlink Pilot Time Slot )、 保 护间隔（ GP， Guard Period )和上行导频时隙（ UpPTS， Uplink Pilot Time Slot )。
Figure imgf000002_0001
从表 1 可以看出， 当不同小区釆用不同的上下行配置时， 终端在某些 上行子帧进行上行传输只会受到其他小区终端上行传输产生的上行干扰， 在另一些上行子帧进行上行传输则可能会受到其他小区基站下行传输产生 的下行干扰。
现有 LTE 系统的上行功率控制机制包括开环功率控制和闭环功率控 制， 其中闭环功率控制又包括累计功率调整和绝对功率调整。 为了克服下 行干扰的影响， 基站可以把上行子帧划分为两个子帧组， 功率调整过程在 两个子帧组上分别进行， 从而可以有效调整终端在属于不同子帧组的上行 子帧上的上行发射功率， 以提升终端的上行传输性能， 尤其是受到下行干 扰的上行子帧上的上行传输性能。
当基站釆用表 1 中的上下行配置方式 0 时， 基站通过下行控制信息 ( DCI , Downlink Control Information ) 格式 0/3/3 A/4 (即 DCI Format 0/3/3 A/4 )发送的传输功率控制（ TPC， Transmit Power Control )命令 ( TPC command )会应用于两个上行子帧， 并且这两个上行子帧属于不同的子帧 组， 导致终端在这两个子帧上的功率调整量相同， 与上文所述的在两个子 帧组上分别进行功率调整的技术思想不符。 其中， 对于 DCI format 3/3A， 目前还没有有效的方案来解决这一问题。 发明内容

在无线帧#N上， eNBl在特殊子帧 1上通过 DCI Format 3发送给终端 UE1的 TPC命令 (假设为 TPC1 )会应用于上行子帧 7和 8; eNBl在特殊 子帧 1上通过 DCI Format 3发送给终端 UE2的 TPC命令（假设为 TPC2 ) 同样会应用于上行子帧 7和 8， 所述过程为现有技术， 此处不在赘述。
本实施例中， eNBl通过重用 DCI Format 3中的 TPC命令域向 UE1、 UE2另外发送一个 TPC命令 (假设为 TPC5 ) ， 用于指示 TPCl、 TPC2所 应用的上行子帧， 也就是说， eNBl发送给 UE1、 UE2的指示信息为同一个 指示信息 TPC5， 如图 10所示， 那么：
UE1根据 TPC5的取值获取 TPC1所应用的上行子帧，如表 2所示， TPC5 的取值所对应的上行子帧由系统配置； 4叚设 TPC5 的取值为 01， 则 TPC1 所应用的上行子帧为子帧 8; 据上述假设， 假设 TPC5的取值为 01， 则 TPC2所应用的上行子帧同样为 子帧 8。
本实施例中， UE1、 UE2还接收 eNBl发送的携带两个 TPC命令索引 的 RRC信令，这两个 TPC命令索引用于供 UE1、UE2从接收到的 DCI Format 3中获取两个 TPC命令。
UE1确定其在上行子帧 8上的功率调整量为 TPC1所对应的功率调整 量； UE2确定其在上行子帧 8上的功率调整量为 TPC2所对应的功率调整 量。
实施例九：
本实施例中， 基站 eNBl釆用表 1中的 TDD上下行配置 0， 并且 eNBl 设置上行子帧分组， 确定上行子帧 2和 7属于上行子帧组一， 确定上行子 帧 3、 4、 8、 9属于上行子帧组二， 基于 TPC命令的功率调整过程在这两 个上行子帧组上分别进行。
在无线帧#N上， eNBl在特殊子帧 1上通过 DCI Format 3A发送给终端 UE1的 TPC命令（假设为 TPC1 )会应用于上行子帧 7和 8， 所述过程为现 有技术， 此处不在赘述。
本实施例中， 由于 DCI Format 3A中的一个 TPC命令只有 lbit， 所以 eNBl通过重用 DCI Format 3A中的 TPC命令域向 UE1另外发送两个 TPC 命令（假设为 TPC5、 TPC6 ) ， 用于指示 TPC1 所应用的上行子帧， 如图 11所示， 包括：
UE1根据 TPC5、 TPC6的取值获取 TPCl所应用的上行子帧， 表 6 为 TPC5和 TPC6的取值对应的子帧索引示意表， 如表 6所示， TPC5、 TPC6 的取值所对应的上行子帧由系统配置；
假设 TPC5的取值为 0， TPC6的取值为 1， 则二者联合指示了 TPC1所 应用的上行子帧为子帧 8。 引
0 0 子帧 7 (或前一个子帧， 或属于上行子帧组一的子帧）
0 1 子帧 8 (或后一个子帧， 或属于上行子帧组二的子帧）
1 0 子帧 7和 8 (或前后两个子帧， 或属于上行子帧组一的 子帧以及属于上行子帧组二的子帧）
1 1 保留
表 6
本实施例中， UE1还接收 eNBl发送的携带三个 TPC命令索引的 RRC 信令， 这三个 TPC命令索引用于供 UE1从接收到的 DCI Format 3A中获取 三个 TPC命令。
UE1确定其在上行子帧 8上的功率调整量为 TPC1所对应的功率调整 量。
实施例十：
本实施例中， 基站 eNBl釆用表 1中的 TDD上下行配置 0， 并且 eNBl 设置上行子帧分组， 确定上行子帧 2属于上行子帧组一， 确定上行子帧 3、 4、 7、 8、 9属于上行子帧组二， 基于 TPC命令的功率调整过程在这两个上 行子帧组上分别进行。
在无线帧#N上， eNBl在特殊子帧 1上通过 DCI Format 3发送给终端 UE1的 TPC命令 (假设为 TPC1 )会应用于上行子帧 7和 8; eNBl在特殊 子帧 6上通过 DCI Format 3发送给 UE1的 TPC命令 (假设为 TPC2 )会应 用于下一个无线帧 #N+1的上行子帧 2和 3， 所述过程为现有技术， 此处不 在赘述。
在本实施例中， eNBl在下行子帧 0上通过 DCI向 UE1发送 TPC命令 (假设为 TPC1* ) ， 用于在上行子帧 4上对物理上行控制信道 PUCCH进 行功率调整； eNBl在特殊子帧 1上通过 DCI向 UE1发送 TPC命令 (假设 为 TPC2* ) ， 用于在上行子帧 7上对物理上行控制信道 PUCCH进行功率 调整； eNBl在下行子帧 5上通过 DCI向 UE1发送 TPC命令 (假设为 TPC3* ), 用于在上行子帧 9上对物理上行控制信道 PUCCH进行功率调整； eNBl在 特殊子帧 6上通过 DCI向 UE1发送 TPC命令 (假设为 TPC4* ) ， 用于在 无线帧 #N+1的上行子帧 2上对物理上行控制信道 PUCCH进行功率调整。
由于上行子帧 4/7/9属于上行子帧组二， 可能会受到严重的下行干扰， 影响 PUCCH的上行传输性能，所以可以考虑限制 PUCCH仅在属于上行子 帧组一的上行子帧上传输， 那么：
由于 TPC1 */TPC2*/TPC3*在对应的上行子帧 4/7/9上并不会得到利用， 可以进一步考虑把这些 TPC命令应用到指定上行子帧的物理上行共享信道 PUSCH上， 例如：
场景一，把 TPC1 *重用到上行子帧 7的 PUSCH上，通过指示信息或通 过系统预定义的方式把 TPC1应用到上行子帧 8上， 如图 12所示； UE1确 定其在上行子帧 7上的功率调整量为 TPC1 *所对应的功率调整量， 确定其 在上行子帧 8上的功率调整量为 TPC1所对应的功率调整量；
或者， 场景二， 把 TPC2*重用于到上行子帧 7的 PUSCH上， 通过指示 信息或通过系统预定义的方式把 TPC1应用到上行子帧 8上，如图 13所示； UE1确定其在上行子帧 7上的功率调整量为 TPC2*所对应的功率调整量， 确定其在上行子帧 8上的功率调整量为 TPC1所对应的功率调整量；
或者， 场景三， 把 TPC3*重用到无线帧 #N+1的上行子帧 2的 PUSCH 上， 通过指示信息或通过系统预定义的方式把 TPC2应用到无线帧 #N+1的 上行子帧 3上， 如图 14所示； UE1确定其在无线帧#N+l的上行子帧 2上 的功率调整量为 TPC3*所对应的功率调整量，确定其在无线帧#N+l的上行 子帧 3上的功率调整量为 TPC2所对应的功率调整量；
