Abstract:
1. A method implemented in a wireless device assembly, the wireless device assembly configured to communicate wirelessly with one or more other devices, the method comprising: receiving, at the wireless device assembly, a first signal from a host assembly, wherein the host assembly is communicatively coupled to the wireless device assembly (i) via a first interface and (ii) via a second interface, wherein the first signal indicates a request for the wireless device assembly to enter a host sleep mode of operation, wherein while the wireless device assembly is in the host sleep mode of operation, the wireless device assembly can initiate communication with the host assembly via the first interface only after receiving a second signal via the second interface, wherein the second signal indicates a request to exit the host sleep mode of operation; in response to the wireless device assembly receiving the first signal, transmitting, via the first interface, a third signal from the wireless device assembly to the host assembly, wherein the third signal indicates entry of the wireless device assembly into the host sleep mode of operation; subsequent to the wireless device assembly transmitting the third signal to the host assembly via the first interface, having the wireless device assembly enter into the host sleep mode of operation; while the wireless device assembly is operating in the host sleep mode of operation, receiving the second signal from the host assembly; transmitting, via the first interface, a fourth signal to the host assembly, wherein the fourth signal is responsive to the second signal; and exiting the host sleep mode of operation in response to receiving a fifth signal from the host assembly, wherein the fifth signal is responsive to the fourth signal.
