Features for increasing sounding reference signal (SRS) resource capacity for wireless communications may include introducing a larger comb size with comb hopping, providing support to determine the slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC), applying RB level frequency hopping within an SRS resource across different symbols, and/or applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource. The TD-OCC may be applied to SRS for codebook, non-codebook and antenna switching, and may also be applied simultaneously with comb hopping and/or RB level hopping in certain scenarios.
