Sounding reference signal resource interference randomization

An apparatus comprising memory coupled to a processor, the processor configured to:

• receive a first sounding reference signal (SRS) hopping identifier;
• use a first initialization seed for a first pseudo-random sequence, based at least in part on the first SRS hopping identifier;
• generate the first pseudo-random sequence, based at least in part on the first initialization seed;
• and
• generate, for transmission, a first SRS transmission in a first SRS resource;
• wherein:
• the first SRS transmission is transmitted in accordance with at least one of a first transmission comb offset, or a first cyclic shift, that is determined based at least in part on the generated first pseudo-random sequence;
• and
• the first SRS hopping identifier corresponds to a first uplink (UL) bandwidth part (BWP) in a first cell.

An apparatus comprising memory coupled to a processor, the processor configured to:

• receive a sounding reference signal (SRS) hopping identifier;
• receive an SRS resource mapping configuration that includes a number of consecutive symbols for SRS transmission and an SRS repetition factor;
• use an initialization seed for a pseudo-random sequence, based at least in part on the SRS hopping identifier;
• generate the pseudo-random sequence, based at least in part on the initialization seed;
• generate, for transmission, a first SRS transmission in a first symbol;
• and
• generate, for transmission, a second SRS transmission in a second symbol;
• wherein:
• the first SRS transmission is transmitted in accordance with at least one of a first transmission comb offset, or a first cyclic shift, that is determined based at least in part on the generated pseudo-random sequence;
• the second SRS transmission is transmitted in accordance with a same transmission comb offset, or a same cyclic shift as the first SRS transmission, based at least in part on the SRS repetition factor;
• and
• the number of consecutive symbols for SRS transmission is greater than the SRS repetition factor.
