METHOD OF TRANSMITTING UPLINK SOUNDING REFERENCE SIGNAL FOR LTE SYSTEM Russian patent published in 2013 - IPC H04B7/208 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a method of transmitting an uplink sounding reference signal (SRS), which includes indexing single carrier frequency division multiple access (SC-FDMA) symbols within a single radio frame for transmitting a SRS in form of a number k, calculating a value of nSRS according to number k and an index number of the radio frames for transmitting the SRS, determining the index number of a frequency-domain start sub-carrier mapped from time-domain SRS symbol with nSRS, and transmitting the SRS through the sub-carrier with the determined index number. Before transmitting the SRS, the start frequency position for SRS should be changed according to the specific frequency-hop pattern to ensure that the UE may uniformly sound the entire SRS frequency-hop bandwidth after multiple soundings.

EFFECT: high accuracy of signal transmission.
