Multi-Band Transceiver Configuration to Reduce Idle Listening Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-band communication devices experience high idle listening power consumption due to simultaneous idle listening on multiple frequency bands, which is a challenge in wireless networks.
Innovation Solution
Implementing a multi-band communication device with transceiver circuitries that can change configurations based on AP configuration information, designating a Primary band for essential communication and Secondary bands for data transmission, and using a multi-band announcement frame to manage radio activation and deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simultaneous idle listening on multiple frequency bands is implemented, then multi-band communication capability is improved, but power consumption increases
Solution Approach 1:
The patent segments the frequency bands into Primary band and Secondary bands. The STA performs idle listening only on the Primary band while Secondary bands are deactivated during idle periods. This segmentation allows the device to maintain multi-band communication capability through configuration information received from the AP, while significantly reducing power consumption by listening on only one band at a time.
2Adaptability or versatility
If transceiver circuitries are configured for multiple frequency bands, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic configuration of transceiver circuitries based on received configuration information from the AP. The band configuration circuitry dynamically activates or deactivates specific transceiver circuitries depending on whether data transmission is required on Primary or Secondary bands. This dynamic approach allows the system to maintain versatility when needed while reducing operational complexity during idle periods.

AI summary
A multi-band communication device includes: one or more transceiver circuitries, each of which in operation transmits and receives data on a plurality of channels in different frequency bands; and a band configuration circuitry operative to change a configuration of any one of the transceiver circuitries based on configuration information received from a multi-band Access Point (AP). The configuration information specifies one of the frequency bands as a Primary band and the other frequency bands as Secondary band(s). The transceiver circuitry operating on the Primary band is used as a default circuitry for communication with the AP.
