Patent number: 11029748Abstract: Systems, methods, and apparatus for adaptively modifying latency times governing entry of a PCIe interface into low power states are described. A method performed by a controller of a PCIe interface includes determining that a burst of data is being transmitted on a PCIe link, configuring a timer to signal when an entry latency period has elapsed after determining that a PCIe link has entered an idle state, causing one or more circuits of the PCIe interface to enter a low-power state when the timer signals that the entry latency period has elapsed before the PCIe link becomes active, and increasing the entry latency period when a number of entries of the PCIe interface to the low-power state that occurs during transmission of the burst of data exceeds a threshold maximum number.Type: GrantFiled: March 15, 2016Date of Patent: June 8, 2021Assignee: QUALCOMM IncorporatedInventors: Neven Klacar, Muralidhar Krishnamoorthy, Hariharan Sukumar

Patent number: 10728870Abstract: Methods and apparatus are provided for avoiding attempts by a UE to attach to a RAT network when that RAT network is unavailable. According to certain aspects, the UE may detect scenarios when the RAT network is unavailable and take preemptive action to prevent the UE from attempting to acquire service on that RAT. For example, the UE may effectively remove that RAT from a list of supported RATs by sending a UE capability message indicating that RAT is not supported, which may prevent network-initiated transitions of the UE to that RAT. The UE may also remove the unavailable RAT from an internal list of supported RATs, which may prevent UE-initiated transitions to that RAT.Type: GrantFiled: October 7, 2013Date of Patent: July 28, 2020Assignee: QUALCOMM IncorporatedInventors: Abhishek Bhatnagar, Shyamal Ramachandran, Vitaly Drapkin, Vamsi Krishna Dokku, Hariharan Sukumar, Zhong Ren, Vidula Rajeev Kurundkar

Patent number: RE49591Abstract: Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.Type: GrantFiled: July 28, 2021Date of Patent: July 25, 2023Assignee: QUALCOMM IncorporatedInventors: Vinod Harimohan Kaushik, Uppinder Singh Babbar, Andrei Danaila, Neven Klacar, Muralidhar Coimbatore Krishnamoorthy, Arunn Coimbatore Krishnamurthy, Vaibhav Kumar, Vanitha Aravamudhan Kumar, Shailesh Maheshwari, Alok Mitra, Roshan Thomas Pius, Hariharan Sukumar
