Apparatus and Method for Sounding Reference Signal Transmission and Apparatus and Method for Sounding Reference Signal Reception

摘要

A method of Sounding Reference Signal (SRS) transmission in a User Equipment (UE) in a communications system using multiple antennas and SRS hopping, the method comprising: identifying a transmission time point of the SRS; setting a transmission band for 5 transmitting the SRS; generating the SRS to be transmitted to a base station; determining an antenna index for transmitting the SRS; and transmitting the SRS to the base station according to the determined antenna index, wherein the antenna index is determined by a function based on the transmission time point, the number of SRS transmission bands allocated to the UE and an SRS bandwidth configuration. ---~~~1 -- --- -- -- --- - C., czCm .2 c= E c= = >% rnn E-E oc C=
