Wireless Device Reporting Time Window for D2D Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices face inefficiencies in reporting to wireless communication networks, particularly in device-to-device communication, leading to increased power consumption and overhead due to periodic reporting requirements, even when out of coverage or in idle mode.
Innovation Solution
Implementing a reporting time window mechanism that allows wireless devices to transmit reports during scheduled data transmissions, reducing the need for separate communication initiations and minimizing power consumption by combining report transmissions with existing data exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices transmit reports periodically to the network, then the network receives timely information, but power consumption increases and communication overhead increases
Solution Approach 1:
The patent implements periodic reporting action by configuring a reporting time window that repeats at defined intervals. The wireless device determines whether to transmit the report based on whether it is scheduled for transmission within the current reporting time window, creating a periodic reporting mechanism that balances timeliness with energy efficiency.
Solution Approach 2:
The patent introduces dynamic adaptation by allowing the wireless device to flexibly determine report transmission timing within the configured reporting time window based on scheduled data transmissions. This dynamic approach enables the device to combine report transmissions with existing data exchanges when possible, reducing unnecessary transmissions and power consumption while still delivering information timely.
2Reliability
If wireless devices initiate separate communication for report transmission, then reports are delivered reliably, but communication overhead increases
Solution Approach 1:
The patent merges report transmission with scheduled data transmissions by allowing the wireless device to determine whether data transmission is scheduled within the reporting time window. When data transmission is scheduled, the report is transmitted together with the data, combining two communication tasks into one and reducing overhead while maintaining reliable report delivery.
Solution Approach 2:
The patent enables the scheduled data transmission to serve multiple functions: transmitting both user data and the measurement report simultaneously. This multi-functionality approach allows a single communication initiation to accomplish both data transfer and reporting tasks, reducing the number of separate communication procedures needed.
3Reliability
If wireless devices transmit reports when out of coverage, then reporting completeness is maintained, but power consumption increases due to re-establishing contact
Solution Approach 1:
The patent applies preliminary action by configuring the reporting time window and transmission conditions in advance while the device is in coverage. When the device goes out of coverage, it can determine whether report transmission is scheduled within the pre-configured window and execute accordingly, avoiding the need to re-establish contact just for reporting and thus reducing power consumption while maintaining reporting completeness.

AI summary
A system includes a network node configured for operation in a wireless communication network. The network node includes radio circuitry and processing circuitry. The processing circuitry is configured to determine a measurement period and an associated reporting window to be used by a wireless device for generating and sending charging reports indicating Device-to-Device (D2D) communications activity by the wireless device. The processing circuitry is further configured to transmit configuration information via the radio circuitry. The configuration information indicates the measurement period and the reporting window.
