ELECTRONIC DEVICE PERFORMING PRECODING DETECTION FOR ADAPTIVE CHANNEL ESTIMATION AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18492187 titled 'ELECTRONIC DEVICE PERFORMING PRECODING DETECTION FOR ADAPTIVE CHANNEL ESTIMATION AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes an electronic device that calculates channel estimation metrics based on cross-correlation of reference signals in different precoding resource block groups to determine the channel estimation mode for a target resource element.
- The device calculates an intra-metric based on cross-correlation of first reference signal symbols in a precoding resource block group to which a target resource element belongs.
- It calculates an inter-metric based on cross-correlation of second reference signal symbols in an adjacent precoding resource block group along a frequency axis, in proximity to the target resource element.
- The device compares the intra-metric and inter-metric to determine the channel estimation mode for the target resource element.

Original Abstract Submitted
An electronic device includes processing circuitry configured to calculate an intra metric based on cross correlation of first reference signal symbols (RSs) included in a first precoding resource block group (PRG) to which a target resource element (RE) belongs, calculate an inter metric based on cross correlation of one or more second RSs and one or more among the first RSs, the one or more second RSs being included in a second PRG adjacent to the first PRG along a frequency axis of a physical channel, the one or more second RSs being in proximity to the target RE, and the physical channel being received from a base station, compare a first ratio between the intra metric and the inter metric with a threshold ratio to obtain a comparison result, and determine a channel estimation mode with respect to the target RE based on the comparison result.
