Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a transmitting UE. The transmitting UE transmits a reference signal and data to one or more receiving UEs. The transmitting UE receives one or more response signals from the one or more receiving UEs on a particular resource element. Each of the one or more response signals represents at least one of (a) a respective indication based on a measurement at a respective receiving UE, of the one or more receiving UEs, transmitting the each response signal and (b) a respective acknowledgment from the respective receiving UE associated with the data. The transmitting UE determines a transmission power at the transmitting UE based on the respective indications. The transmitting UE transmits data to the one or more receiving UEs at the transmission power.

Abstract: Techniques and examples of overhead reduction for linear combination codebook and feedback mechanism in mobile communications are described. A user equipment (UE) receives from a base station of a network one or more reference signals via a communication link between the UE and the base station. The UE constructs a channel state information (CSI) feedback by utilizing a correlation of channel responses in a frequency domain to reduce feedback overhead. The UE then transmits the CSI feedback to the base station.
