Abstract
User Equipment (UE) selects a Sounding Reference Signal (SRS) pattern and transmits orthogonal frequency-division multiplexing (OFDM) symbols according to the selected SRS pattern. The OFDM communication system wirelessly receives data from the UE and processes the data to detect the OFDM symbols. The detected OFDM symbols are processed to identify the selected SRS pattern. An impulse response matrix is generated based on the selected SRS pattern. Additional data based on the impulse response matrix can be transferred to the UE.
