摘要： Methods and devices configured to apply a power back-off (PBO) to limit a radio frequency (RF) transmitter power up to a first limit, where the first limit is below a pre-defined RF power limit; accumulate a difference between RF transmission power spent transmitting data and the pre-defined RF power limit over a duration to produce an accumulated energy budget; and once the accumulated energy budget reaches a pre-defined energy credit value, remove the PBO and allow RF transmitter power exceeding the pre-defined RF power limit until the accumulated energy budget meets a threshold.

摘要： A device including one or more processors configured to: determine a disconnection margin value based on: a current transmission operation state including one or more transmission control parameters, and a current transmission rate; receive a power back-off (PBO) request including a PBO value; perform a comparison of the PBO value to the disconnection margin value; and determine whether to apply a PBO according to the PBO request based on the comparison.

摘要： To control transmit power in a wireless device, the wireless device sends a data indication signal to the network adaptor. The data indication signal can indicate a transmission status of data to be transmitted and being located in at least one queue of a network stack of a computing device of wireless device. The network adaptor can determine using a time-averaged specific absorption rate (SAR) function, a transmit power for wireless transmission of data in the network adaptor by considering at least the data in the network adaptor and the at least one data indication signal.

摘要： Device and methods to receive an instruction to apply a requested power back-off (PBO) for transmitting a data packet at an adjusted transmission power adapted from a current transmission power; estimate a first energy quantity for transmitting the data packet based on the adjusted transmission power and a first estimated length of time for transmitting the data packet at the adjusted transmission power; determine the second transmission power that is greater than the adjusted transmission power and estimate a second energy quantity based on the second transmission power and a second estimated length of time for transmitting the data packet at the second transmission power, where the second energy quantity is less than the first energy quantity; and apply the second PBO based on the second transmission power for transmitting the data packet instead of applying the requested PBO.

摘要： Devices and methods for providing communication channel congestion levels to determine whether to apply power and/or time back-offs, and if so, how to apply said back-offs. The device may be configured to estimate a congestion level of a communication channel, wherein the congestion level indicates an availability for transmissions over one or more time periods; determine a projected time back-off for an ensuing packet transmission based on the congestion level; and determine whether to apply a transmission back-off based on the projected time back-off and a transmission energy budget based on one or more time-averaging specific absorption rate (TAS) parameters for regulating a radiation exposure to a user of the device.

摘要： Performing a synchronization to allow a second wireless communication circuit of a wireless device operating in a second wireless communication network to operatively coexist with a first wireless communication network of the wireless device operating in a first wireless communication network in one or more wireless communication channels according to a time division multiplexing (TDM), wherein the method includes determining whether the one or more wireless communication channels are busy comprising determining whether a packet has been detected by the wireless device in the one or more wireless communication channels and/or determining whether the wireless device has sensed energy in the one or more wireless communication channels when one or more back-off counters associated TDM plan is zero; and granting to the second communication network, in response to determining the one or more wireless communication channels are busy, use of the one or more wireless communication channels.
