Precoding Matrix Continuity Detection for Channel Estimation

The patent applies dynamics by making the precoding matrix selection adaptive and variable across frequency resources. The base station dynamically selects precoding matrices based on channel conditions, and the mobile station adaptively determines smoothing applicability based on continuity detection between adjacent frequency resources. This dynamic adaptation allows the system to optimize reception power through dedicated beam forming while maintaining channel estimation accuracy by adjusting smoothing processing according to actual continuity conditions.

The patent applies local quality by enabling the mobile station to perform local determination of smoothing applicability for each frequency resource based on detected continuity of precoding matrices. Instead of uniformly applying smoothing across all frequencies, the system selectively applies smoothing only where precoding matrices are continuous, while avoiding smoothing where discontinuities exist. This localized adaptive approach ensures high channel estimation accuracy across varying channel conditions.

The patent applies self-service by enabling the mobile station to autonomously detect continuity of precoding matrices between adjacent frequency resources and independently determine whether smoothing processing should be applied. The base station transmits only necessary indication information, while the mobile station performs the complex tasks of continuity detection and smoothing determination without requiring base station intervention. This self-service mechanism reduces overall system complexity while maintaining high adaptability to changing channel conditions.
