Wireless Electronic Apparatus Response Frame Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication techniques that transmit data to multiple base stations simultaneously increase overhead due to sequential Ack frame reception from each base station, compromising communication reliability.
Innovation Solution
An electronic apparatus that overlaps the transmission period of response frames from multiple wireless base stations, allowing simultaneous Ack frame reception without increasing overhead, by configuring the apparatus to transmit Ack frames after a short inter-frame spacing, ensuring reliable communication without sequential time-sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless terminal sequentially refers to responses from multiple wireless base stations in a time-sharing manner, then the overhead is increased, but the communication reliability is improved through multiple base station transmission
Solution Approach 1:
The patent merges the response frames from multiple wireless base stations into a single time slot by overlapping their transmission periods. The wireless terminal receives multiple response frames simultaneously during the same time period, and only one response frame is selected for data extraction. This combining approach eliminates sequential time-sharing, reduces overhead time, and maintains communication reliability through multiple base station participation.
2Loss of time
If response frames from multiple wireless base stations are transmitted simultaneously with overlapping periods, then the overhead is reduced, but interference between responses may occur
Solution Approach 1:
The patent applies preliminary action by having wireless base stations pre-coordinate their response frame transmission timing before actual data transmission. The base stations are configured to transmit response frames in overlapping time periods that are预先 arranged, ensuring that the wireless terminal can receive them simultaneously without unexpected interference. This pre-planned timing coordination eliminates random interference while maintaining reduced overhead.

AI summary
According to one embodiment, an electronic apparatus includes a receiver and a transmitter. The receiver is configured to receive, from a first wireless apparatus, a first physical frame including a destination address receivable by a second wireless apparatus different from the electronic apparatus. The transmitter is configured to transmit, to the first wireless apparatus, a first response frame including first information regarding the first physical frame, if the first physical frame is successfully received. A transmission period of the first response frame at least partially overlaps with a transmission period of a second response frame including second information regarding the first physical frame received by the second wireless apparatus.
