1. A method comprising:
receiving first information for a set of uplink (UL) bandwidth parts (BWPs) of a serving cell, wherein the set of UL BWPs includes more than one UL BWP;
receiving second information, for each UL BWP from the set of UL BWPs, for sounding reference signal (SRS) resource sets;
receiving third information that provides:
a first periodicity for SRS transmissions only in an active UL BWP, and
a second periodicity for SRS transmissions in each UL BWP from the set of UL BWPs;
determining, for each UL BWP from the set of UL BWPs, corresponding first SRS resources from the SRS resource sets;
transmitting a first SRS in the active UL BWP according to the first periodicity; and
transmitting a second SRS, in each UL BWP from the set of UL BWPs, according to the second periodicity and using the corresponding first SRS resources.
