Uplink multi-beam operation

A method for wireless communication, comprising:

• receiving, by a user equipment (UE), downlink control information (DCI) indicating that an uplink data signal is to be transmitted using two or more transmission beams during different transmission time intervals (TTIs) and at least one sounding reference signal (SRS) resource indicator, the SRS resource indicator comprises an index to power control parameters;
• determining, based at least in part on the at least one SRS resource indicator, a transmission beam cycling scheme for the uplink data signal;
• and
• transmitting, based at least in part on the power control parameters, a plurality of repetitions of the uplink data signal, wherein each repetition is transmitted on a different TTI using a different one of the two or more transmission beams based at least in part on the transmission beam cycling scheme.

A method for wireless communication, comprising:

• receiving a grant indicating resources for an uplink data transmission;
• receiving at least one sounding reference signal (SRS) resource indicator, the SRS resource indicator comprises an index to power control parameters;
• determining a default beam cycling scheme for uplink control signals;
• determining, based at least in part on the default beam cycling scheme for a control channel, a beam cycling scheme for the uplink data transmission;
• and
• transmitting, based at least in part on the power control parameters, a plurality of repetitions of the uplink data signal, wherein each repetition is transmitted on a different transmission time interval (TTI) using a different one of two or more transmission beams based at least in part on the determined beam cycling scheme for the uplink data transmission.

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, by the apparatus, a downlink control signal comprising one or more sounding reference signal (SRS) resource indicators, the SRS resource indicator comprises an index to power control parameters, the downlink control signal indicating that an uplink control signal is to be transmitted using two or more transmission beams during different transmission time intervals (TTIs);
• identify the two or more transmission beams based at least in part on the downlink control signal;
• and
• transmit, based at least in part on the power control parameters, a plurality of repetitions of the uplink control signal, wherein each repetition is transmitted on a different TTI using a different one of the two or more transmission beams based at least in part on the downlink control signal.
