Default channel state information (CSI)-reference signal (RS) beam

A method for wireless communication by a user-equipment (UE), comprising:

• receiving an indication of a plurality of beam configurations;
• determining whether the plurality of beam configurations are different than a first beam configuration for processing at least one channel state information (CSI)-reference signal (RS);
• selecting a second beam configuration for processing the at least one CSI-RS based on the determination;
• receiving the at least one CSI-RS;
• and
• processing the at least one CSI-RS based on the selected second beam configuration,
• wherein the second beam configuration for processing the at least one CSI-RS is selected based on the determination if a period between the reception of the at least one CSI-RS and reception of downlink control information (DCI) that schedules resources for the at least one CSI-RS is less than a beam switching threshold.

A method for wireless communication, comprising:

• determining whether a plurality of beam configurations configured for transmission of one or more downlink (DL) signals are different than a first beam configuration for transmission of at least one channel state information (CSI)-reference signal (RS), the one or more DL signals to be transmitted in the same symbol as the at least one CSI-RS;
• selecting a second beam configuration for transmission of the at least one CSI-RS based on the determination;
• and
• transmitting, to a user-equipment (UE), the at least one CSI-RS based on the selected second beam configuration,
• wherein the second beam configuration for transmission of the at least one CSI-RS is selected based on the determination if a period between the reception of the at least one CSI-RS and reception of downlink control information (DCI) that schedules resources for the at least one CSI-RS is less than a beam switching threshold.
