METHOD FOR TRANSMITTING UPPERLINK SOUNDING REFERENCE SIGNAL FOR LTE SYSTEM Russian patent published in 2017 - IPC H04B7/208 

FIELD: radio engineering, communication.

SUBSTANCE: method for transmitting the upperlink sounding reference signal comprises indexing symbols of single-carrier frequency-division multiple access (SC-FDMA) in one radio signal frame for transmitting the sounding reference signal (SRS) as a number k, calculating a value of n_SRS in accordance with the number k and the sequence number of the radio signal frame for the transmission of the SRS, determining the sequence number of the initial subcarrier in the frequency domain converted from the time domain SRS symbol with n_SRS, and transmitting the SRS by the subcarrier with a specific sequence number. Before transmitting the SRS, the initial frequency position for the SRS should be changed according to the specific frequency hopping pattern to ensure that the UE can uniformly probe the entire SRS frequency hopping bandwidth after several soundings.

EFFECT: implementation of frequency hopping of the upperlink transmission signal.
