Patent number: 10972973Abstract: Two methods for energy-efficient idle listening enhancement for WLAN systems are provided. The first method performs a change of operation of a station (STA) from an active mode to an idle listening mode without notifying the change to an access point (AP) associated with the STA. In the idle listening mode, the AP may transmit frames to the STA using a higher bandwidth, but the STA can only sense channels in a lower bandwidth to save energy. The second method transmits a frame to the AP associated with the STA to notify the AP the change of operation of the STA from the active mode to the idle listening mode. In the idle listening mode, the AP may transmit frames to the STA using the lower bandwidth, and the STA can only sense channels in the lower bandwidth to save energy.Type: GrantFiled: October 2, 2019Date of Patent: April 6, 2021Assignee: Cypress Semiconductor CorporationInventors: Kamesh Medapalli, Rajendra Kumar Gundu Rao, Xianmin Wang, Sangho Seo

Publication number: 20200396625Abstract: Disclosed are methods and systems for delaying packet transmissions over a wireless communication channel until a more favorable channel condition is detected. A device may measure a channel metric when it receives periodic beacon signals. The device may compare the channel metric against a programmed metric threshold. If the channel metric is less than the metric threshold, the device may delay the transmission of a packet until a later transmission window or transmit opportunity (TXOP) when the channel metric rises above the metric threshold, indicating the presence of a more favorable condition for transmission, or until a preconfigured timeout period elapses before the more favorable condition is found.Type: ApplicationFiled: June 14, 2019Publication date: December 17, 2020Applicant: Cypress Semiconductor CorporationInventors: Prasanna Kumar Sethuraman, Rajendra Kumar Gundu Rao, Ayush Sood, Paul Strauch
