摘要:
A method and system for selecting a thermally optimal airlink for a portable computing device includes monitoring a temperature of the portable computing device as well as determining if the portable computing device has reached a threshold temperature range. Next, an estimated volume of data to be sent over one or more airlinks may be calculated in addition to determining an estimated duration for the data using one or more airlinks. A quality of service needed for the data in connection with the one or more airlinks may be determined. With this estimated data, one or more available airlinks for the data to be transmitted may be compared. After this comparison, one or more thermally optimal airlinks may be selected based on the estimated volume, estimated data rate, and estimated duration. Determining if the portable computing device is proximate to an operator may be used when considering airlinks.
摘要:
A method and system for reducing thermal load by monitoring temperatures within a portable computing device and, based on those temperatures, controlling a battery charge function are disclosed. The method includes monitoring a power management integrated circuit ("PMIC") to determine if it is generating excess thermal energy that is contributory to an elevated temperature in a physically proximate application specific integrated circuit ("ASIC"). If so, and if the excess thermal energy is attributable to an ongoing battery recharge operation executed by the PMIC, a thermal policy manager module may execute a thermal mitigation technique algorithm to override the PMIC battery recharge function. One exemplary thermal mitigation technique may include a reduction of current sent to the battery, thus slowing the charge cycle and reducing the generation of excess thermal energy.
摘要:
A method and system for managing one or more thermal policies of a portable computing device (PCD) includes monitoring temperature of the portable computing device with internal thermal sensors and external thermal sensors. If a change in temperature has been detected by at least one thermal sensor, then a thermal policy manager may increase a frequency in which temperature readings are detected by the thermal sensors. The thermal policy manager may also determine if a current temperature of the portable computing device as detected by one or more of the thermal sensors falls within one or more predetermined thermal states. Each thermal state maybe assigned a unique set of thermal mitigation techniques. Each set of thermal mitigation techniques may be different from one another. The sets of thermal mitigation techniques may differ according to quantity of techniques and impacts on performance of the PCD.

A technique for uplink data throttling includes buffer status report (BSR) scaling. A target data flow rate may be determined based on at least on condition of a wireless device. The buffer status report may be adjusted to cause the target flow rate and transmitted by the wireless device. The wireless device may then receive a flow control command based on the buffer status report.
