Time-division multiplexing sounding reference signal ports

A method of wireless communication at a user equipment (UE), comprising:

• spatial time-division multiplexing a plurality of sounding reference signal (SRS) ports based on a transient period between two consecutive symbols of the plurality of spatially time-division multiplexed SRS ports, each of the plurality of SRS ports being associated with at least one of a set of orthogonal weights, the set of orthogonal weights corresponding to phase shifting, wherein the transient period starts from a transient start time and is provided for the phase shifting between the two consecutive symbols;
• and
• transmitting, to a base station, a plurality of SRSs via the plurality of spatially time-division multiplexed SRS ports simultaneously, each of the plurality of SRSs including at least two SRS repetitions.

A method of wireless communication at a base station (BS), comprising:

• transmitting, to a user equipment (UE), a configuration of spatial time-division multiplexing for the UE to spatially time-division multiplex a plurality of sounding reference signal (SRS) ports, each of the plurality of SRS ports being associated with at least one of a set of orthogonal weights, the set of orthogonal weights corresponding to phase shifting, and wherein a transient period is set between two consecutive symbols of the plurality of spatially time-division multiplexed SRS ports, wherein the transient period starts from a transient start time and is provided for the phase shifting between the two consecutive symbols;
• and
• receiving, from the UE, a plurality of SRSs via the plurality of spatially time-division multiplexed SRS ports simultaneously, each of the plurality of SRSs including at least two SRS repetitions.
