Front loaded csi-rs based feedback

A first user equipment (UE) for wireless communication in a bundled Transmission Time Interval (TTI) comprising at least a first TTI and a second TTI, the first UE comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, at the first UE, a first data transmission directly from a second UE in the first TTI;
• receive, at the first UE, a first reference signal directly from the second UE;
• transmit a feedback to the second UE based on the first reference signal;
• and
• receive a second data transmission from the second UE in the second TTI or a subsequent TTI, the second data transmission having one or more transmission parameters adapted based on the feedback transmitted to the second UE.

A method of wireless communication at a first user equipment (UE) in a bundled Transmission Time Interval (TTI) comprising at least a first TTI and a second TTI, the method comprising:

• transmitting a first data transmission directly to a second UE in the first TTI;
• transmitting a first reference signal directly to the second UE;
• receiving a feedback from the second UE based on the first reference signal;
• adapting one or more transmission parameters based on the feedback received from the second UE;
• and
• transmitting a second data transmission to the second UE in the second TTI or a subsequent TTI, the second data transmission having the one or more transmission parameters adapted based on the feedback received from the second UE.
