Patent number: 11601832Abstract: 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: GrantFiled: July 16, 2021Date of Patent: March 7, 2023Assignee: Cypress Semiconductor CorporationInventors: Prasanna Kumar Sethuraman, Rajendra Kumar Gundu Rao, Ayush Sood, Paul Strauch

Publication number: 20220286975Abstract: Disclosed are methods and systems for tailoring the transmit power of a wireless device to the parameters of the device such as the process split, voltage, and temperature. The device may identify one or more parameters of the device such as identifying the process split, or sensing the operating voltage or temperature. The device may determine an updated transmit power based on the known parameter values identified and any unknown parameter values. The updated transmit power is determined to be a maximum transmit power that meets one or more target transmit metrics, such as EVM and spectral mask, when the device transmits based on the known parameter values and across a range of variations of the unknown parameter values. The device may adjust its transmit power based on the updated transmit power periodically.Type: ApplicationFiled: March 24, 2022Publication date: September 8, 2022Applicant: Cypress Semiconductor CorporationInventors: Ayush Sood, Kamesh Medapalli, Rajendra Kumar Gundu Rao, Patrick Cruise, Roshni Sulekhakumari, Manoj George
