Release Assistance Indication Assertion for Wireless Transceiver Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies do not provide techniques for endpoints to determine when and how to assert a release assistance indication (RAI) to terminate data session windows early, leading to inefficient power consumption in battery-powered devices.
Innovation Solution
A computer-implemented method that identifies data to be transmitted and, upon determining no further data is ready, instructs the transceiver to end the data session window early and transition to a lower power state, using techniques such as sending a command signal or embedding an RAI bit in data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transceiver remains active throughout the entire time slot to ensure no incoming transmission is missed, then communication reliability is improved, but power consumption increases significantly
Solution Approach 1:
The endpoint performs preliminary actions by transmitting all anticipated data before the time slot ends and asserting RAI to terminate the time slot early. This allows the transceiver to switch to lower power state before the scheduled end time, reducing power consumption while maintaining communication reliability through proper data transmission completion.
Solution Approach 2:
The system uses feedback mechanisms where the endpoint monitors data transmission status and uses this information to determine when to assert RAI. The network node also provides feedback through the time slot structure, allowing the endpoint to optimize power consumption based on actual transmission needs while ensuring reliable communication.
2Productivity
If the endpoint keeps the transceiver active during the entire time slot, then data transmission completeness is ensured, but battery lifetime is reduced
Solution Approach 1:
The endpoint transmits all data that needs to be sent during the time slot before asserting RAI to terminate the time slot early. This preliminary data transmission ensures completeness while enabling early transceiver shutdown, thereby extending battery lifetime for battery-powered devices.
Solution Approach 2:
The system changes the time slot duration parameter by allowing early termination through RAI assertion. This parameter change enables the transceiver to operate in lower power state for a longer effective duration, extending battery lifetime while maintaining data transmission completeness through proper data buffering and transmission management.
3Use of energy by moving object
If the endpoint asserts RAI to terminate the time slot early, then power consumption is reduced, but the complexity of determining when and how to use RAI increases
Solution Approach 1:
The endpoint performs self-service by autonomously determining when to assert RAI based on its own data transmission status. The endpoint monitors its data buffer and transmission progress, making decisions about RAI assertion without requiring complex external control or network coordination, thereby reducing overall system complexity while achieving power savings.
Solution Approach 2:
The patent extracts the RAI assertion logic from complex network-controlled mechanisms and simplifies it to endpoint-autonomous decision-making based on local data transmission status. This extraction reduces the complexity of determining when and how to use RAI by focusing on simple local conditions rather than complex network-state coordination.

AI summary
Techniques for transmitting data include one or more processors of a computing device included in a network device identifying data to be transmitted; and while a data session window is open: transmitting, using a transmitter of the network device, the data to a transceiver that is included in the network device and is separate from the one or more processors, wherein the transceiver is configured to transmit the data outside of the network device; and in response to determining that there is no additional data to be transmitted, (a) delaying for a period of time, and (b) after the period of time, instructing the transceiver to end the data session window early and transition to a lower power state.
