Frequency Block Emphasis for Priority Data Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with narrow antenna bandwidth, such as those implementing LTE standards, amplitude variation across OFDMA resource blocks can lead to weak or improper reception of priority data due to its location within the spectrum, causing communication inefficiencies.
Innovation Solution
The electronic device identifies subsets of frequency blocks containing higher priority data and emphasizes these blocks through baseband filtering and antenna matching networks to increase their amplitude and center the output frequency response, ensuring higher signal quality and reduced retransmissions.

If narrow bandwidth antennas are used in electronic devices, then device size is reduced, but amplitude variation across OFDMA resource blocks increases causing improper reception of priority data
Solution Approach 1:
The patent applies local quality by adjusting the amplitude of specific frequency blocks (resource blocks) individually based on their content priority. High-priority data in frequency blocks experiencing amplitude attenuation are identified and their amplitudes are boosted selectively, rather than uniformly adjusting all frequencies. This resolves the contradiction by maintaining device compactness while locally correcting reception quality issues in affected frequency regions.
Solution Approach 2:
The patent changes the amplitude parameter of specific frequency blocks dynamically based on detected signal conditions and data priority. By monitoring the received signal and identifying which resource blocks contain high-priority data that are affected by amplitude variation, the system adjusts transmission parameters to compensate for the narrow bandwidth antenna's frequency response characteristics, thereby maintaining reliable reception despite physical constraints.
2Device complexity
If amplitude variation across resource blocks is not compensated, then device complexity is reduced, but data communication efficiency decreases due to retransmissions
Solution Approach 1:
The patent implements preliminary action by detecting and identifying high-priority data in frequency blocks before transmission or during initial reception processing. By pre-identifying which resource blocks contain critical information and predicting which frequencies may be affected by amplitude variation, the system prepares compensation strategies in advance, avoiding the need for complex real-time corrections and reducing retransmissions, thus improving communication efficiency without excessive complexity.
Solution Approach 2:
The patent employs feedback mechanisms where the receiver monitors the quality of received data in different frequency blocks and sends feedback information about reception conditions and priority data identification to the transmitter. This feedback loop enables the transmitter to adjust its signal characteristics for subsequent transmissions, compensating for amplitude variation effects and improving overall communication efficiency through iterative optimization rather than complex upfront processing.

AI summary
A method is performed in an electronic device for emphasizing frequency blocks containing priority data. The method includes: determining to communicate data in a plurality of allocated frequency blocks; identifying a first subset of the plurality of allocated frequency blocks that contain data having a higher priority than data in a second subset of the plurality of allocated frequency blocks; and emphasizing, during data communication, the first subset of the plurality of allocated frequency blocks, which contain the data having the higher priority, over the second subset of the plurality of allocated frequency blocks.
