1. A method comprising:receiving at a user equipment a configuration of multiple sounding reference signal parameter sets each set including a timing indication;
receiving at the user equipment being configured with the sounding reference signal parameter sets a grant that allocates multiple uplink subframes;
based on the grant, determining whether at least one of the multiple allocated uplink subframes is shortened such that uplink transmission is prohibited in only a portion thereof, and, if affirmative, which of the multiple uplink subframes are shortened;
determining from the grant that a sounding reference signal is requested;
determining from the grant a selected one of the sounding reference signal parameter sets;
identifying one uplink subframe based on the determination which of the multiple allocated uplink subframes are shortened and the timing indication of the selected sounding reference signal parameter set; and
transmitting the sounding reference signal as requested by the grant in the identified uplink subframe.
