Communication Apparatus Queue-Based Wake-Up Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, particularly in IoT devices and IEEE 802.11ba standard compliant systems, face inefficiencies in power consumption and communication band usage due to frequent wake-up frames being transmitted for each bufferable unit, leading to potential communication band tightness and increased power consumption.
Innovation Solution
A communication apparatus with a selection unit that determines whether to transmit a wake-up frame based on the amount of data accumulated in the transmission queue, using a power-efficient communication unit to optimize communication band usage and reduce power consumption by selectively transitioning between wake-up and doze states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a WUR wake-up frame is transmitted each time a bufferable unit is received, then data transmission reliability is improved, but communication band efficiency deteriorates
Solution Approach 1:
The patent merges multiple wake-up frame transmissions into a single transmission by accumulating bufferable units in a transmission queue and selecting whether to transmit based on the accumulated amount, thereby combining multiple potential transmissions into one efficient operation
Solution Approach 2:
The patent performs preliminary accumulation of bufferable units in the transmission queue before deciding on wake-up frame transmission, allowing the system to prepare data in advance and make informed decisions about when to transmit
2Productivity
If the primary connectivity radio is frequently transitioned to awake state, then data transmission capability is improved, but power consumption increases
Solution Approach 1:
The patent accumulates bufferable units in the transmission queue before triggering a wake-up frame transmission, allowing the system to prepare data in advance and reduce unnecessary frequent transitions of the primary connectivity radio to awake state
Solution Approach 2:
The patent implements periodic checking of the transmission queue and selective transmission based on accumulated data amount, creating a rhythm of transmission that avoids continuous or overly frequent wake-up frame transmissions
3Loss of time
If wake-up frames are transmitted frequently, then data delivery timeliness is improved, but communication band usage efficiency deteriorates
Solution Approach 1:
The patent accumulates bufferable units in the transmission queue before transmission, preparing data in advance to enable timely delivery when transmission conditions are favorable, while avoiding unnecessary transmissions
Solution Approach 2:
The patent dynamically adjusts transmission behavior based on the accumulated data amount in the transmission queue, making adaptive decisions about when to transmit wake-up frames rather than using a fixed transmission schedule

AI summary
If a communication apparatus is to transmit data to another communication apparatus and communication via a communication unit included in the other communication apparatus is not performable, whether or not to transmit a frame for causing a transition to a state where the communication via the communication unit included in the other communication apparatus is performable is selected based on an amount of data accumulated in a transmission queue in which the data is stored.
