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 20240137081 titled 'ELECTRONIC DEVICE PERFORMING PRECODING DETECTION FOR ADAPTIVE CHANNEL ESTIMATION AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes an electronic device that calculates metrics based on cross correlation of reference signal symbols in different precoding resource block groups to determine a channel estimation mode.
- The electronic device calculates an intra metric based on cross correlation of first reference signal symbols in a first 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 a second precoding resource block group adjacent to the first group along a frequency axis.
- The device compares the intra and inter metrics to determine a channel estimation mode with respect to 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.
