Abstract

提供一种在通用地面无线接入UTRA时分双工TDD高码片速率HCR系统中，在下行高速物理共享信道HS－PDSCH停止发送期间在用户终端UE侧计算信道质量指示CQI的方法，包括步骤：UE在HS－PDSCH停止发送期间，获得有关无线信道环境的变化的信息；UE在HS－PDSCH发送期间，根据在上述步骤中所获得的无线信道环境的变化的信息产生CQI参考值，根据在HS－PDSCH发送期间无线信道环境的变化对所述CQI参考值进行修正以得到CQI修正值，并基于该CQI修正值得到正确的CQI最终值。本发明还提供用于实现上述方法的装置、无线通信系统和程序产品及其存储介质。本发明的方法使得UE在HS－PDSCH停止发送期间，也能够正确地估计信道质量指示CQI。
