Abstract
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.
Claims20
A wireless device comprising:
- a network adaptor;
- a computing device operably coupled to the network adaptor, the computing device configured to:
- send at least one data indication signal to the network adaptor, the at least one data indication signal indicating a transmission status of data to be transmitted and being located in at least one queue of a network stack of the computing device, the layer being at least one of a medium access control (MAC) layer or a layer above the MAC layer;
- wherein the network adaptor is configured to:
- determine, in a MAC or physical (PHY) layer of the network adaptor using a time-averaged specific absorption rate (SAR) function, a transmit power for 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.
A method comprising:
- obtaining, by a network adaptor from a computing device, at least one data indication signal indicating a transmission status of data to be transmitted and being located in at least one queue of a network stack of the computing device, the layer being at least one of a medium access control (MAC) layer or a layer above the MAC layer;
- determining, in a MAC or physical (PHY) layer of the network adaptor in a MAC or physical (PHY) layer, a transmit power for transmission of data in the network adaptor, using a time-averaged specific absorption rate (SAR) function that considers at least the data in the network adaptor and the at least one data indication signal.
A non-transitory computer-readable medium containing instructions that when executed by at least one processor cause the at least one processor to:
- obtain, from a computing device, at least one data indication signal indicating a transmission status of data to be transmitted and being located in at least one queue of a network stack of the computing device, the layer being at least one of a medium access control (MAC) layer or a layer above the MAC layer;
- determine, in a MAC or PHY layer of network adaptor, by using a time-averaged specific absorption rate (SAR) function, a maximum transmit power for transmission of data in the network adaptor based at least on the data in the network adaptor and the at least one data indication signal.
