Abstract
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting sounding reference signal (SRS) resources with frequency hopping. In some implementations, a user equipment (UE) may use different SRS ports, different antenna ports, different numbers and sizes of SRS resources, different periodicities, different offsets, different transmission comb values, different number of symbols, different power control parameters, and/or different transmission comb offset values for SRS transmissions on different frequency subbands of the frequency hopping pattern to ensure that sounding operations cover all antennas of the UE, cover the entire frequency range of interest, and provide sufficiently dense SRS transmissions from which a base station can determine the best channel for DL transmissions while also using a minimum amount of SRS resources and consuming minimal power in the UE.
