Method for a UE for requesting a channel state information reference signal (CSI-RS) or a sounding reference signal (SRS)

An apparatus for wireless communication, comprising:

• at least one processor;
• a transceiver communicatively coupled to the at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• transmit a message that requests a scheduling entity to schedule a transmission of a reference signal for the apparatus, wherein the message includes one or more spatial quasi co-location (QCL) indications;
• obtain an assignment of resources for the transmission of the reference signal in response to the message, wherein the assignment of resources specifies at least one of the one or more spatial QCL indications;
• and
• transmit the reference signal based on the assignment of resources, wherein the apparatus transmits the reference signal using one or more transmission directivity patterns compatible with the specified at least one of the one or more spatial QCL indications.

A method of wireless communication, comprising:

• obtaining, at a scheduling entity, a message that requests the scheduling entity to schedule a transmission of at least one reference signal for a scheduled entity, wherein the message includes one or more spatial quasi co-location (QCL) indications;
• transmitting, from the scheduling entity, a first assignment of resources to the scheduled entity for the transmission of the at least one reference signal in response to the message wherein the first assignment of resources indicates that the at least one reference signal is to be transmitted using one or more transmission directivity patterns, at least one of the one or more transmission directivity patterns being compatible with at least one of the one or more spatial QCL indications;
• and
• obtaining, at the scheduling entity, the at least one reference signal from the scheduled entity.
