Description

一种信道盾量指示 COI的上报方法及用户设备 技术领域
本发明涉及通信技术领域，特别涉及一种信道质量指示 CQI的上报方法及 用户设备。 背景技术
随着通信技术的飞速发展， 宽带码分多址 （Wideband Code Division Multiple Access, WCDMA )作为第三代移动通信系统的主流技术之一， 在全 球范围内得到了广泛的研究和应用。 在通用移动通信系统（Universal Mobile Telecommunications System, UMTS ) 中， 为了提升下行吞吐速率， 引入了多 流传输机制机制 （ Multi-Flow , MF ) , 又称高速下行分组接入多点传输 ( High-speed Downlink Packet Access multipoint transmission , HSDPA-MP-Tx )。
MF机制中包含多种传输模式， 主流的传输模式包括单频-双小区 SF-DC ( Single Frequency-Double Cell ) 模式， 双频 -3小区 DF-3C ( Double
Frequency-3Cell )模式， 双频 -4小区 DF-4C ( Double Frequency-4Cell )模式。 其中单频-双小区 SF-DC的架构如图 la所示。
在图 la中表示的是 Inter-NodeB SF-DC (即两个小区属于不同的 NodeB )的 情况，其中，服务高速下行共享信道小区（ Serving High Speed Downlink Shared Channel cell , Serving HS-DSCH cell ) 对应的基站称为服务基站（Serving
NodeB), 辅助服务高速下行共享信道小区 （ Assisting Serving HS-DSCH cell ) 对应的基站称为辅助服务基站（ Assisting Serving NodeB ), 服务基站和辅助服 务基站均与基站控制器（RNC )连接， 并且通过 HS-DSCH与用户设备 UE进行 数据传输。
在现有技术中， UE周期性的通过 HS-DSCH的上行高速专用物理控制信道
( High Speed Dedicated Physical Control Channel, HS-DPCCH )上才艮信道质量 指示 （Channel Quality Indicator, CQI ), 基站根据 CQI调度下行数据； SF-DC 中两个小区的 CQI ( CQI1 , CQI2 )是通过联合编码方式在同一个传输时间间 隔 （TTI ) 内上报给基站。
而对于 DF-3C的架构如图 lb所示， 图 lb表示的是 Inter-NodeB DF-3C (即三 个小区属于不同 NodeB )的情况，与 SF-DC类似，在频点 fl时， Serving HS-DSCH cell对应的基站称为服务基站 （Serving NodeB ), 与之对应的配对频点 f2上的 小区称为第二服务高速下行共享信道（Secondary Serving HS-DSCH ) 小区， 第二服务高速下行共享信道小区也对应服务基站； Assisting Serving HS-DSCH 小区对应的基站称为辅助服务基站 （Assisting Serving NodeB )。 在图 lb中， CELL1和 CELL3称为一个组（ group ), 同一 group小区的 CQI是釆用联合反馈方 式， 即 CELL1和 CELL3的 CQI釆用联合反馈， CELL2 的 CQI单独反馈， 但均 为单一的周期性反馈。
再请参考图 lc所示， 为 DF-4C的架构图， 表示的是 Inter-NodeB DF-4C (即 4个小区属于不同 NodeB ) 的情况， 与 DF-3C类似， 在频点 fl时， Serving HS-DSCH cell对应的基站称为服务基站（ Serving NodeB ), 与之对应的配对频 点 £2上的小区称为第二服务高速下行共享信道（ Secondary Serving HS-DSCH ) 小区， 第二服务高速下行共享信道小区也对应服务基站； Assisting Serving HS-DSCH小区对应的基站称为辅助服务基站（Assisting Serving NodeB ), 与 Assisting Serving HS-DSCH小区对应的配对频点 f2上的小区称为辅助第二服 务 HS-DSCH小区（ Assisting Secondary Serving HS-DSCH Cell ),辅助第二服务 HS-DSCH小区同样也对应辅助服务基站。 在图 lc†， CELL1和 CELL3称为一 个组（ group ), CELL2和 CELL4称为一个 group, 同一 group小区的 CQI是釆用 联合反馈方式， 即 CELL1和 CELL3的 CQI釆用联合反馈， CELL2 和 CELL4的 CQI釆用联合反馈方式， 但均未单一的周期性反馈。
然而， 本发明人在实现本发明实施例中的技术方案的过程中发现， 在 MF 机制下， 不管在哪种 UE釆用单一的周期性反馈方式上报 CQI, 例如固定釆用 2ms的上报周期， 那么不管是否有需要， UE都会上报， 那么就使得上行控制 信道的开销较大。 发明内容

实施例一
本实施例是站在 UE侧对本发明进行描述，如图 2所示，本发明实施例提 供一种 CQI的上报方法， 应用于多流传输 MF机制中， 该方法包括：
步骤 101 : 用户设备获得多流传输中服务小区的服务小区 CQI和辅助服 务小区的辅助服务小区 CQI;
步骤 102:在服务小区的服务小区 CQI和辅助服务小区 CQI至少一个 CQI 满足触发上报条件时， 用户设备向基站上报服务小区 CQI和 /或辅助服务小区 CQI, 以减少上行控制信道开销。
其中， 在本发明实施例中， 服务小区和辅助服务小区在不同的传输模式 下， 含义稍有不同， 相应的， 服务小区 CQI和辅助服务小区 CQI在不同的传 输模式下含义也稍有不同。
在 Inter-NodeB SF-DC传输模式下，服务小区即为服务高速下行共享信道 小区 （ Serving HS-DSCH cell ), 后称为小区 1 , 辅助服务小区即为辅助服务高 速下行共享信道小区 （ Assisting Serving HS-DSCH cell ), 后称为小区 2, 相应 的，服务小区 CQI即为服务高速下行共享信道小区 CQI( Serving HS-DSCH cell CQI ), 后称为 CQI1 , 辅助服务小区 CQI即为辅助服务高速下行共享信道小 区 ( Assisting Serving HS-DSCH cell CQI ), 后称为 CQI2; 进一步， 在该传输 模式下， CQI1和 CQI2通过联合编码方式在同一个 TTI内上报给服务基站和 辅助服务基站， 即 CQI1和 CQI2为一个 CQI组， 进行联合上报。
在 Inter-NodeB DF-3C传输模式下， 服务小区包括小区 1和第二服务高速 下行共享信道小区 （Secondary Serving HS-DSCH cell ), 其中， 第二服务高速 下行共享信道小区后称为小区 3; 辅助服务小区即为小区 2; 相应的， 服务小 区 CQI包括 CQI1和第二服务高速下行共享信道小区 CQI, 其中， 第二服务 高速下行共享信道小区 CQI后称为 CQI3 , 而辅助服务小区 CQI即为 CQI2; 进一步， 在该传输模式下， CQI1和 CQI3为一个 CQI组， 进行联合上报给服 务基站， CQI2自身为一个 CQI组， 进行单独上报给辅助服务基站。
在 Inter-NodeB DF-4C传输模式下， 服务小区包括小区 1和小区 3 , 辅助 服务小区包括小区 2 和辅助第二服务 HS-DSCH 小区 （Assisting Secondary Serving HS-DSCH Cell ), 其中， 辅助第二服务 HS-DSCH小区后称为小区 4; 相应的， 服务小区 CQI包括 CQI1和 CQI3 , 辅助服务小区包括 CQI2和辅助 第二服务 HS-DSCH小区 CQI, 其中，辅助第二服务 HS-DSCH小区 CQI后称 为 CQI4; 进一步， 在该模式下， CQI1和 CQI3为一个 CQI组， 进行联合上报 给服务基站， CQI2和 CQI4为一个 CQI组， 进行联合上报给辅助服务基站。
在具体实施过程中， 步骤 101具体可以通过如下公式来计算获得 CQI:
CQI = (^)CP1CH +MPO + \0x\ogw (\6) + 4.5
N。 ，其中， （ Ec/No ) CPICH是公共导频信 道（ Common Pilot Channel; CPICH )信噪比， MPO是偏值。
在实际运用中， 还可以釆用其他获取 CQI值的方法， 这部分为本领域技 术人员所熟知的内容， 所以在此不再赘述。
当在步骤 101中获取到服务小区 CQI和辅助服务小区 CQI之后， 接下来 就执行步骤 102: 即在所述服务小区的服务小区 CQI和辅助服务小区 CQI至 少一个 CQI满足触发上报条件时，用户设备向基站上报服务小区 CQI和 /或辅 助服务小区 CQI, 以减少上行控制信道开销。 其中， 基站具体为服务基站和 / 或辅助服务基站。 需要说明的是， 所述减少上行控制信道开销是相对于现有 技术的单一固定周期上报 CQI的技术方案而言。
在具体实施过程中， 步骤 102具有多种不同的实施形态， 以下将举例对 不同的实施形态进行详细描述。
第一实施形态， 步骤 102具体为： 达到第一上报周期时， 用户设备判定 服务小区 CQI和辅助服务小区 CQI中至少有一个 CQI与该一个 CQI的前一次 上报的 CQI的差值大于或等于门限值， 则按照第一上报周期上报该一个 CQI 所在的 CQI组； 或
若达到第一上报周期时，用户设备判定服务小区 CQI和辅助服务小区 CQI 中所有 CQI与各自前一次上报的 CQI的差值均小于门限值， 则不上报服务小 区 CQI和辅助服务小区 CQI。
在 Inter-NodeB SF-DC传输模式下， 步骤 102具体为： 达到第一上报周期 时，用户设备判定 CQI1和 CQI2中至少有一个 CQI与该一个 CQI的前一次上 报的 CQI的差值大于或等于门限值， 则按照第一上报周期上报该一个 CQI所 在的 CQI组； 若达到第一上 >¾周期时， 用户设备判定 CQI1和 CQI2中所有 CQI与各自前一次上报的 CQI的差值均小于门限值， 则不上报服务小区 CQI 和辅助服务小区 CQI。
具体来说， 在 Inter-NodeB SF-DC传输模式下， 步骤 101 中获得的 CQI 为 CQI1和 CQI2, 那么在步骤 102中， 假设第一上报周期为 2毫秒（ms ), 达 到第一上报周期时， 用户设备判断 CQI1与前一次上报的 CQI1的差值是否大 于等于门限值， 例如， 步骤 101获得的 CQI1为 7 , 前一次上报的 CQI1为 9, 那么差值为 2,假设门限值为 1 ,那么判断的结果就是该差值是大于门限值的， 为一个肯定的结果； 类似的， 用户设备还判断 CQI2与前一次上报的 CQI2的 差值是否大于或等于门限值。
在实际运用中， 为了节约资源和时间， 可以先判断 CQI1和 CQI2中的任 意一个， 如果结果是肯定的， 例如前述 CQI1与前一次上报的差值为 2, 大于 门限值 1 ,那么就可以不再判断 CQI2 ,然后直接按照 2ms的上报周期上报 CQI1 和 CQI2。 如果对于 CQI1或 CQI2的判断结果是否定的， 那么接下来再判断 另一个， 例如先判断 CQI1 , 如果结果是否定的， 那么就再继续判断 CQI2, 如果对 CQI2的判断结果是肯定的，那么就按照 2ms的上报周期上报 CQI1和 CQI2, 而如果 CQI2的判断结果也是否定的， 即 CQI1和 CQI2与各自前一次 上报的 CQI值均小于门限值， 那么就不上报 CQI1和 CQI2, 即不上报 CQI1 和 CQI2。 然后再重复执行步骤 101和步骤 102。
当然， 在另一实施例中， 用户设备也可以同时判断 CQI1和 CQI2。
在 Inter-NodeB DF-3C传输模式下， 步骤 102具体为： 达到第一上 期 时， 用户设备判定 CQI1和 CQI3、 CQI2中至少有一个 CQI与该一个 CQI的 前一次上报的 CQI的差值大于或等于门限值， 则按照第一上报周期上报该一 个 CQI所在的 CQI组；若达到第一上报周期时，用户设备判定 CQI1和 CQI3、 CQI2中所有 CQI与各自前一次上报的 CQI的差值均小于门限值， 则不上报 服务小区 CQI和辅助服务小区 CQI。
具体来说， 在 Inter-NodeB DF-3C传输模式下， 服务小区 CQI包括 CQI1 和 CQI3 , 辅助服务小区 CQI为 CQI2, 那么在该模式下， 用户设备利用与上 述类似的判断方法判断 CQI1和 CQI3、CQI2中是否有至少一个 CQI与前一次 上报的 CQI的差值大于或等于门限值， 假设判断的结果表示 CQI1和 CQI3、 CQI2中有一个满足判断条件， 如果满足判断条件的是 CQI1和 /或 CQI3 , 那 么就上报 CQI1和 CQI3的 CQI组， 而不上报 CQI2; 如果满足判断条件的是 CQI2, 那么就上报 CQI2, 而不上报 CQI1和 CQI3的 CQI组； 如果所有 CQI ( CQI1、 CQI2、 CQI3 )都不满足判断条件， 那么就不上报所有 CQI。
在 Inter-NodeB DF-4C传输模式下， 步骤 102具体为： 达到第一上 期 时， 用户设备判定 CQI1和 CQI3、 CQI2和 CQI4中至少有一个 CQI与该一个 CQI的前一次上报的 CQI的差值大于或等于门限值， 则按照第一上报周期上 报该一个 CQI所在的 CQI组； 若达到第一上报周期时， 用户设备判定 CQI1 和 CQI3、 CQI2和 CQI4中所有 CQI与各自前一次上 >¾的 CQI的差值均小于 门限值， 则不上报服务小区 CQI和辅助服务小区 CQI。
具体来说， 在 Inter-NodeB DF-4C传输模式下， 服务小区 CQI包括 CQI1 和 CQI3 , 辅助服务小区 CQI包括 CQI2和 CQI4, 那么在该模式下， 用户设备 利用与上述类似的判断方法判断 CQI1和 CQI3、 CQI2和 CQI4中是否有至少 一个 CQI与前一次上报的 CQI的差值大于或等于门限值， 假设判断的结果表 示 CQI1和 CQI3、 CQI2和 CQI4中有一个满足判断条件， 如果满足判断条件 的是 CQI1和 /或 CQI3 , 那么就上报 CQI1和 CQI3的 CQI组， 而不上报 CQI2 和 CQI4的 CQI组；如果满足判断条件的是 CQI2和 /或 CQI4,那么就上报 CQI2 和 CQI4的 CQI组，而不上报 CQI1和 CQI3的 CQI组；如果所有 CQI ( CQI1、 CQI2、 CQI3、 CQI4 )都不满足判断条件， 那么就不上报所有 CQI。
由以上描述可以看出， 在本实施例中， 只有在当前 CQI与前一次上 "^的 CQI的差值大于或等于门限值时， 即当前 CQI和前一次上 "^的 CQI的差异比 较大时， 才会上报 CQI, 而在差异不大时， 就不上报 CQI, 所以相比一个固 定周期上 >¾的方法， 能够减少上行控制信道的开销。
步骤 102的第二实施形态， 在本实施例中， 用户设备每上 一次 CQI, 就启动或重启第一定时器， 在第一定时器运行期间， 用户设备按照前述第一 实施形态中的方法上 >¾ CQI。 如果直到第一定时器满时， 所有 CQI与各自前 一次上报的 CQI的差值均小于门限值， 那么在第一定时器满时， 就上报所有 CQI。
结合第一实施形态，步骤 102具体还包括：在按照第一上报周期上报 CQI 组时启动或重启第一定时器； 在第一定时器满时， 用户设备上 ^该 CQI组； 其中第一定时器的初始值大于第一上^^周期。
继续先以 Inter-NodeB SF-DC传输模式为例进行说明，假设第一上报周期 为 2ms, 而第一定时器的初始值为 10ms。 达到第一上报周期时， 用户设备判 断的结果是 CQI1和 CQI2中至少有一个 CQI与该一个 CQI的前一次上报的 CQI的差值大于或等于门限值， 那么就以 2ms上报 CQI1和 CQI2的 CQI组， 并启动或重启第一定时器，假设为正计时的方式， 即从 0ms到 10ms的时间增 力口。
假设在 2ms时， 用户设备判断的结果是否定的， 即所有 CQI与各自前一 次上报的 CQI的差值均小于门限值， 那么就不上报 CQI1和 CQI2的 CQI组； 然后在 4ms时， 用户设备判断的结果是肯定的， 那么就要上报 CQI1和 CQI2 的 CQI组， 在上报时， 第一定时器又被重启， 又从 0ms开始计时， 重复上述 过程直至某一次在整个第一定时器运行期间， 用户设备对所有的 CQI的判断 结果都是否定的， 即在整个第一定时器运行期间， 用户设备都没有上报 CQI1 和 CQI2的 CQI组，那么在第一定时器满时，就上报所有 CQI1和 CQI2的 CQI 组， 并重启第一定时器， 重复上述过程。 其中， 第一定时器的初始值大于第 一上报周期。
对于 Inter-NodeB DF-3C传输模式和 Inter-NodeB DF-4C传输模式， 情形 与 Inter-NodeB SF-DC传输模式类似，只是对应每个 CQI组都会配置一个第一 定时器， 即对每个 CQI组每上报一次 CQI, 都会启动或重启与该 CQI组对应 的第一定时器， 在整个第一定时器运行期间， 用户设备按照第一实施形态上 报该 CQI组， 该对应的第一定时器满后， 用户设备上报该 CQI组， 并重启该 对应的第一定时器， 重复上述过程。
具体来说， 例如以 Inter-NodeB SF-DC传输模式为例， 假设第一上报周期 为 2ms, 达到第一上报周期时， 用户设备判断的结果是 CQI1与前一次上报的 CQI1的差值大于门限值， CQI4判断的结果也是肯定的， 那么就上报 CQI1和 CQI3的 CQI组， 并启动或重启 CQI1和 CQI3的 CQI组对应的第一定时器； 也上报 CQI2和 CQI4的 CQI组， 并启动或重启 CQI2和 CQI4的 CQI组对应 的第一定时器。
假设在第 2ms时， 用户设备判断的结果是 CQI1与前一次上报的 CQI1的 差值大于门限值， 而 CQI4与前一次上报的 CQI4的差值小于门限值， 那么就 上报， CQI1和 CQI3的 CQI组， 并重启 CQI1和 CQI3的 CQI组对应的第一 定时器， 而不上 ^艮 CQI2和 CQI4的 CQI组， 那么 CQI2和 CQI4的 CQI组对 应的第一定时器就还处于运行阶段。 如果， 在 CQI2和 CQI4的 CQI组对应的 第一定时器运行到第 4ms时，用户设备再次判断 CQI2和 CQI4中是否其中有 一个 CQI与该一个 CQI前一次上报的 CQI的差值大于或等于门限值，如果结 果是肯定的， 例如 CQI2满足判断条件， 那么， 就上报 CQI2和 CQI4的 CQI 组， 而 CQI2和 CQI4的 CQI组对应的第一定时器又被重启，又从 0ms开始计 时，重复上述过程直至某一次在整个 CQI2和 CQI4的 CQI组对应的第一定时 器运行期间， 用户设备对所有的 CQI的判断结果都是否定的， 即在整个第一 定时器运行期间，用户设备都没有上报 CQI2和 CQI4的 CQI组，那么在 CQI2 和 CQI4的 CQI组对应的第一定时器满时， 就上报 CQI2和 CQI4的 CQI组， 并重启 CQI2和 CQI4的 CQI组对应的第一定时器， 重复上述过程。 其中， 第 一定时器的初始值大于第一上报周期。
而在 CQI2和 CQI4的 CQI组对应的第一定时器运行到第 4ms时， CQI1 和 CQI3的 CQI组对应的第一定时器因为被重启，这时运行到了第 2ms,那么 用户设备再次判断 CQI1和 CQI3中是否其中有一个 CQI与该一个 CQI前一次 上报的 CQI的差值大于或等于门限值， 如果结果是肯定的， 例如 CQI1满足 判断条件， 那么， 就上报 CQI1和 CQI3的 CQI组， 而 CQI1和 CQI3的 CQI 组对应的第一定时器又被重启， 又从 0ms开始计时， 重复上述过程直至某一 次在整个 CQI1和 CQI3的 CQI组对应的第一定时器运行期间，用户设备对所 有的 CQI的判断结果都是否定的， 即在整个第一定时器运行期间， 用户设备 都没有上报 CQI1和 CQI3的 CQI组， 那么在 CQI1和 CQI3的 CQI组对应的 第一定时器满时， 就上报 CQI1和 CQI3的 CQI组， 并重启 CQI1和 CQI3的 CQI组对应的第一定时器， 重复上述过程。
通过本实施例， 可以避免长时间不上报 CQI而影响下行调度。
第三实施形态， 在本实施例中， 步骤 102具体包括： 当用户设备收到基 站发送的下行数据或 CQI激活指令时， 启动或重启第二定时器；
在第二定时器运行期间， 用户设备按照第一上报周期上报 CQI;
在第二定时器满后，
达到第一上报周期时， 用户设备判定服务小区 CQI和辅助服务小区 CQI中至少有一个 CQI与该一个 CQI的前一次上 ^的 CQI的差值大于或等于 门限值， 则按照第一上报周期上报该一个 CQI所在的 CQI组； 或
若达到第一上报周期时， 用户设备判定服务小区 CQI和辅助服务小 区 CQI中所有 CQI与各自前一次上报的 CQI的差值均小于门限值，则不上报 服务小区 CQI和辅助服务小区 CQI;
其中， 第二定时器的初始值大于第一上报周期。
即在本实施例中， 不管用户设备是从服务小区还是辅助服务小区接收到 下行数据包、 或者是接收到基站发送的 CQI激活指令时， 都会启动或重启第 二定时器； 在第二定时器运行期间， 就按照第一上报周期上报所有 CQI; 而 在第二定时器满后， 就按照第一实施形态中的方法进行上报。 因为有接收到 下行数据或 CQI激活指令， 则表示这时需要频繁上报 CQI, 而在第二定时器 满后， 在没有接收到下行数据或 CQI激活指令之前， 就表示这时对 CQI的需 求不是很高， 所以较佳的， 第二定时器的初始值大于第一上报周期的值， 例 如第一上报周期为 2ms, 而第二定时器的初始值为 8ms。
进一步， 在第二定时器满后， 以第一实施形态中的方法上报 CQI, 使得 CQI上报更加符合实际需要， 进而进一步减少上行控制信道的开销。
同样， 本实施例中的方法适用于前述三种传输模式。
第四实施形态， 在本实施例中， 步骤 102具体为： 用户设备接收到多流 传输中的服务小区和辅助服务小区中任一小区发送的 CQI激活指令或下行数 据时， 以第一上报周期上报服务小区 CQI和辅助服务小区 CQI。 其中， CQI 激活指令可以但不限于通过高速共享控制信道指令（ HS-SCCH order )来承载。 比如收到服务小区的激活指令或下行数据时， 则立即上报 CQI, 然后以第一 上报周期周期性的上报 CQI。
例如在 Inter-NodeB SF-DC传输模式下， 用户设备接收到小区 1或小区 2 中任一小区发送的 CQI 激活指令或下行数据， 就以第一周期上报 CQI1 和 CQI2。 第一周期例如为 2ms。
在 Inter-NodeB DF-3C传输模式下， 用户设备接收到小区 1、 小区 2、 小 区 3 中任一小区发送的 CQI激活指令或下行数据， 就以第一周期上报 CQI1 和 CQI3、 CQI2。 第一周期例如为 2ms。
类似的， 在 Inter-NodeB DF-4C传输模式下， 用户设备接收到小区 1小区 2、 小区 3和小区 4中任一小区发送的 CQI激活指令或下行数据， 就以第一周 期上报 CQI1和 CQI3、 CQI2和 CQI4。 第一周期例如为 2ms。
在进一步的实施例中， 用户设备在接收到服务小区中任一服务小区发送 的 CQI去激活指令， 则用户设备进入去激活状态， 不上报服务小区 CQI和辅 助服务小区 CQI。 其中， CQI去激活指令可以但不限于通过 HS-SCCH order 来承载。
例如在 Inter-NodeB SF-DC传输模式下， 用户设备接收到小区 1发送的 CQI去激活指令， 就不上报 CQI1和 CQI2。 在实际运用中， 也可以由小区 2 发送 CQI去激活指令。
在 Inter-NodeB DF-3C传输模式下， 用户设备接收到小区 1和 /或小区 3 中发送的 CQI去激活指令， 就不再按照第一周期上报 CQI1和 CQI3、 CQI2。 在实际运用中， 也可以由小区 2发送 CQI去激活指令。
类似的， 在 Inter-NodeB DF-4C传输模式下， 用户设备接收到小区 1和 / 或小区 3发送的 CQI去激活指令， 就不上报 CQI1和 CQI3、 CQI2和 CQI4。 在实际运用中， 也可以由小区 2或小区 4发送 CQI去激活指令。
通过本实施例， 只有在接收到 CQI激活指令或下行数据时， 才上报 CQI, 在接收到 CQI去激活指令时， 就不上报 CQI, 所以也能够减少不必要的上行 控制信道的开销。
进一步， 在以第一上报周期上报 CQI时， 还可以进一步结合第一实施形 态中的方法来上 CQI, 以进一步减少上行控制信道的开销。
第五实施形态， 在本实施例中， 步骤 102具体包括： 用户设备在接收到 多流传输中的服务小区和辅助服务小区中任一小区发送的 CQI激活指令时， 启动或重启第三定时器；
在第三定时器运行期间， 以第一上报周期上报服务小区 CQI和辅助服务 小区 CQI;
在第三定时器满后，用户设备进入 CQI去激活状态，不上报服务小区 CQI 和辅助服务小区 CQI; 或者用户设备以第二上报周期上报服务小区 CQI和辅 助服务小区 CQI, 其中第二上报周期大于第一上报周期。 其中， CQI激活指 令可以但不限于通过高速共享控制信道指令（ HS-SCCH order ) 来承载。
在本实施例中， 用户设备接收 CQI激活指令后， 立即上报 CQI, 并启动 或重启第三定时器， H没第三定时器的初始值为 10ms, 在第三定时器运行期 间， 用户设备以 2ms的第一周期上 所有 CQI, 而当第三定时器满后， 用户 设备就自动进入去激活状态， 不上报所有 CQI, 直至再次收到 CQI激活指令， 再重启第三定时器， 重复上述过程即可。 比如用户设备进入 CQI去激活状态 后， 收到基站发送的 CQI激活指令或下行数据， 则立即上报 CQI并重启该第 三定时器， 并且定时器运行期间后继续以该第一周期周期性地上报 CQI。
在另一实施例中， 当第三定时器满时， 用户设备以第二上报周期上报服 务小区 CQI和辅助服务小区 CQI, 其中第二上报周期大于第一上报周期。 第 二周期例如为 16ms。
在本实施例中， 不需要基站发送 CQI去激活指令， 用户设备可以自适应 进入去激活状态， 所以可以减少信令交互。
较佳的， CQI激活指令和 CQI去激活指令由服务小区发送， 当然， 在实 际运用中， 也可以由辅助服务小区发送。
同样， 本实施例中的方法适用于前述三种传输模式。
进一步， 在以第一上报周期和第二周期上报 CQI时， 同样也可以结合第 一实施形态中的方法进行上 ·¾。
在前述第四实施形态和第五实施形态中， 由服务小区或辅助服务小区发 送 CQI激活指令， 触发用户设备上报 CQI, 而服务小区或辅助服务小区具体 为在有下行数据发送给该用户设备时， 下发 CQI激活指令给用户设备； 或当 服务小区和辅助服务小区持续一定时间没有数据发送给用户设备时，下发 CQI 去激活指令给用户设备。 第六实施形态， 在本实施例中， 步骤 102具体为： 用户设备接收到服务 小区和辅助服务小区分别发送的调整 CQI周期指令时， 则以调整 CQI周期指 令中包含的最小 CQI周期为上报周期上报服务小区 CQI和辅助服务小区 CQI。
例如 CQI上报周期预配有 2ms、 8ms、 16ms, 以 Inter-NodeB DF-3C传输 模式为例， 小区 1发送给用户设备的调整 CQI周期指令中包含的 CQI周期为 2ms,而小区 2发送给用户设备的调整 CQI周期指令中包含的 CQI周期为 8ms, 那么用户设备就以 2ms为上报周期上报所有 CQI。
进一步， 在以最小 CQI周期上报 CQI时， 同样也可以结合第一实施形态 中的方法进行上报。
调整 CQI周期指令可以但不限于通过高速共享控制信道指令（ HS-SCCH order ) 来承载。 比如 HS-SCCH order 中有两个值， "上升（UP )" 和 "下降 ( Down )" , UP就表示配置的较长 CQI上报周期（比如 16ms ), down表示配 置的较短 CQI上报周期。再比如， HS-SCCH order中有三个值， "上升（UP )"、 "保持（Hold )" 下降（Down )" , UP就表示配置的较长 CQI上报周期 （比 如 16ms ), down表示配置的较短 CQI上报周期， Hold就表示用配置的 CQI 上报周期中间值来上报 CQI (比如 8ms )„
第七实施形态， 在本实施例中， 步骤 102具体为用户设备接收到服务小 区发送的指示迁入长 CQI周期的指令时，以长 CQI周期上报服务小区 CQI和 辅助服务小区 CQI。 周期为 16ms, 短 CQI周期为 2ms。 用户设备如果接收到服务小区发送的指示 迁入长 CQI周期的指令时，就以长 CQI周期上报服务小区 CQI和辅助服务小 区 CQI, 即 16ms。
相应的， 在用户设备接收到服务小区发送的指示迁入短 CQI周期的指令 时， 就以短 CQI周期上报服务小区 CQI和辅助服务小区 CQI。
在本实施例中， 通过长短周期交叉使用， 减少上行控制信道的开销。 可以结合第一实施形态中的方法进行上报。
第八实施形态， 与第七实施形态类似， 只是在本实施例中， 用户设备在 接收到服务小区发送的指示迁入长 CQI周期的指令时， 启动第四定时器； 若 在第四定时器运行期间， 用户设备未收到下行数据或辅助服务小区发送的指 示迁入短 CQI周期的指令时，以长 CQI周期上报服务小区 CQI和辅助服务小 区 CQI。
即在本实施例中， 用户设备在接收到服务小区发送的指示迁入长 CQI周 期的指令时， 并不立即以长 CQI周期上报 CQI, 而是启动或重启第四定时器， 判断在第四定时器运行期间， 是否有接收到下行数据或辅助服务小区发送的 指示迁入短 CQI周期的指令， 如果有， 则表示当前不宜迁入长 CQI周期， 如 果没有， 那么就表示暂时不需要频繁上报 CQI, 那么就在第四定时器满时， 以长 CQI周期上报 CQI。
进一步， 在用户设备迁入长 CQI周期后， 如果接收到服务小区发送的指 示迁入短 CQI周期的指令， 或者接收到服务小区或辅助服务小区发送的下行 数据时， 就迁入短 CQI周期， 以短 CQI周期上报 CQI。
在本实施例中， 通过长短周期交叉使用， 减少上行控制信道的开销。 进一步， 在第七实施形态和第八实施形态中， 在以长 CQI周期上 "^ CQI 或以短 CQI周期上 CQI时， 同样也可以结合第一实施形态中的方法进行上 报。
具体来说， 以长 CQI周期上报 CQI具体包括： 达到长 CQI周期时， 用户 设备判定服务小区 CQI和辅助服务小区 CQI中至少有一个 CQI与该一个 CQI 的前一次上报的 CQI的差值大于或等于门限值， 则按照第一上报周期上报该 一个 CQI所在的 CQI组； 或达到长 CQI周期时， 用户设备判定服务小区 CQI 和辅助服务小区 CQI中所有 CQI与各自前一次上报的 CQI的差值均小于门限 值， 则不上报服务小区 CQI和辅助服务小区 CQI。
而以短 CQI周期上报 CQI具体包括： 达到短 CQI周期时， 用户设备判定 服务小区 CQI和辅助服务小区 CQI中至少有一个 CQI与一个 CQI的前一次上 报的 CQI的差值大于或等于门限值， 则按照第一上报周期上报一个 CQI所在 的 CQI组； 或达到短 CQI周期时， 用户设备判定服务小区 CQI和辅助服务小 区 CQI中所有 CQI与各自前一次上报的 CQI的差值均小于门限值，则不上报 服务小区 CQI和辅助服务小区 CQI。
第九实施形态， 在本实施例中， 步骤 102具体包括： 用户设备在接收到 服务小区或辅助服务小区发送的下行数据时， 启动或重启第五定时器； 在第 五定时器运行期间， 用户设备按照短 CQI周期上报服务小区 CQI和辅助服务 小区 CQI; 在第五定时器满后， 用户设备按照长 CQI周期上报服务小区 CQI 和辅助服务小区 CQI; 或者用户设备进入去激活状态， 不上报服务小区 CQI 和辅助服务小区 CQI。
进一步， 为了避免用户设备在第五定时器满后， 以长 CQI周期上报 CQI 的时间过长影响下行调度， 在用户设备按照长 CQI周期上报服务小区 CQI和 辅助服务小区 CQI后， 该方法还包括： 用户设备在接收到服务小区发送的迁 入短 CQI周期的指令或 CQI激活指令时， 以短 CQI周期上报服务小区 CQI 和辅助服务小区 CQI。
在本实施例中， 通过长短周期交叉使用， 减少上行控制信道的开销。 可以结合第一实施形态中的方法进行上报。
第十实施形态， 在本实施例中， 用户设备侧分别为服务基站和辅助服务 基站分别启动一个定时器 T1和定时器 T2, 定时器 T1和定时器 T2分别基于 服务基站和辅助服务基站发送的下行数据包启动或重启； 服务基站和辅助服 务基站也分别启动定时器 T1和定时器 T2, 定时器 T1和定时器 T2定时器均 满后， 按照长 CQI周期上报 CQI。
即当用户设备接收到服务基站发送的第一下行数据时， 启动或重启定时 器 T1 , 当用户设备接收到辅助服务基站发送的第二下行数据时， 启动或重启 定时器 T2;
在定时器 T1和 /或定时器 T2运行期间，用户设备以短 CQI周期上报 CQI; 在定时器 T1和定时器 T2均满后， 用户设备按照长 CQI周期上 CQI。 而为了服务基站和辅助服务基站能够得知当前的 CQI上报周期， 那么服 务基站和辅助服务基站侧也分配配置定时器 T1和定时器 T2, 并在分别发送 第一下行数据和第二下行数据时启动或重启定时器 T1和定时器 T2, 服务基 站和辅助服务基站通过 RNC进行交互， 以告知对方自身侧的定时器是在运行 或已截止， 那么在接收到对方发送的定时器情况， 再根据自身侧的定时器运 行状况， 就可以得知当前的 CQI上报周期。
在本实施例中， 通过长短周期交叉使用， 减少上行控制信道的开销。 可以结合第一实施形态中的方法进行上报。
通过以上对各个实施形态的详细描述可以看出， 本发明实施例中， 在服 务小区的服务小区 CQI和辅助服务小区 CQI至少一个 CQI满足触发上报条件 时， 用户设备向基站上报服务小区 CQI和 /或辅助服务小区 CQI, 以减少上行 控制信道开销， 即在本实施例中， 不再像现有技术一样， 釆用一个固定周期 上报 CQI, 不管基站是否需要， 例如每 2ms上报一次， 而本发明实施例是在 服务小区的服务小区 CQI和辅助服务小区 CQI至少一个 CQI满足触发上报条 件时才上报， 在满足 CQI触发上报条件的情况下上报 CQI, 使得 CQI上报更 符合实际情况， 既满足需要， 又减小了上行控制信道的开销。

在以上各实施例中， 在不冲突的情况下， 可以相互组合实施。 适用于本实施例的用户设备， 通过前述对 CQI的上报方法的详细描述， 本领 域技术人员可以清楚的知道本实施例中用户设备的实施方法， 所以为了说明 书的简洁， 在此不再详述。
本发明实施例中提供的一个或多个技术方案， 至少具有如下技术效果或 优点：
本发明实施例中， 在服务小区的服务小区 CQI和辅助服务小区 CQI至少 一个 CQI满足触发上报条件时，用户设备向基站上报服务小区 CQI和 /或辅助 服务小区 CQI, 以减少上行控制信道开销， 即在本实施例中， 不再像现有技 术一样， 釆用一个固定周期上报 CQI, 不管基站是否需要， 例如每 2ms上报 一次， 而本发明实施例是在服务小区的服务小区 CQI和辅助服务小区 CQI至 少一个 CQI满足触发上报条件时才上报， 在满足 CQI触发上报条件的情况下 上报 CQI, 使得 CQI上报更符合实际情况， 既满足需要， 又减小了上行控制 信道的开销。
本领域内的技术人员应明白， 本发明的实施例可提供为方法、 系统、 或 计算机程序产品。 因此， 本发明可釆用完全硬件实施例、 完全软件实施例、 或结合软件和硬件方面的实施例的形式。 而且， 本发明可釆用在一个或多个 其中包含有计算机可用程序代码的计算机可用存储介质 (包括但不限于磁盘 存储器、 CD-ROM、 光学存储器等）上实施的计算机程序产品的形式。
本发明是参照根据本发明实施例的方法、 设备（系统）、 和计算机程序产 品的流程图和 /或方框图来描述的。 应理解可由计算机程序指令实现流程图 和 /或方框图中的每一流程和 /或方框、 以及流程图和 /或方框图中的流程 和 /或方框的结合。 可提供这些计算机程序指令到通用计算机、 专用计算机、 嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器， 使得通 过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流 程图一个流程或多个流程和 /或方框图一个方框或多个方框中指定的功能的 装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设 备以特定方式工作的计算机可读存储器中， 使得存储在该计算机可读存储器 中的指令产生包括指令装置的制造品， 该指令装置实现在流程图一个流程或 多个流程和 /或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上， 使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的 处理， 从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图 一个流程或多个流程和 /或方框图一个方框或多个方框中指定的功能的步 骤。
尽管已描述了本发明的优选实施例， 但本领域内的技术人员一旦得知了 基本创造性概念， 则可对这些实施例做出另外的变更和修改。 所以， 所附权 利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。 脱离本发明实施例的精神和范围。 这样， 倘若本发明实施例的这些修改和变 型属于本发明权利要求及其等同技术的范围之内， 则本发明也意图包含这些 改动和变型在内。
