A wireless device determines spatial characteristics of reference signals at different frequencies using a mapping function that correlates frequency-dependent characteristics.

Patentradars sammanfattning

The invention relates to a method and system for determining spatial characteristics of reference signals across different frequencies in wireless communications. A wireless device measures spatial characteristics (such as phase or amplitude) of first reference signals at a first frequency, then applies a mapping function dependent on both frequencies to predict corresponding spatial characteristics of second reference signals at a second frequency. This mapping approach eliminates the need for independent measurement of reference signals at every frequency, improving system efficiency.
