Sony patents method for phones to switch radio settings while idle
Sony describes a way for mobile devices to receive instructions from a cell tower while they are in a low-power 'idle' or 'inactive' mode. The device can switch between two specific radio frequency bands that overlap in time and frequency, allowing it to stay connected without fully waking up.
In the filing’s own words
A method of operating a communications device configured to transmit signals to and/or to receive signals from wireless communications networks is provided. The method comprises operating in one of an idle state and an inactive state and, when operating in the one of the idle state and the inactive state, receiving, via a broadcasted signal from the wireless communications network, a configuration of at least two bandwidth parts, BWPs, for use by the communications device in transmitting signals to and/or receiving signals from the wireless communications network while remaining in the one of the idle state and the inactive state. Radio resources forming a first of the BWPs at least partially overlap in both frequency and time with radio resources forming a second of the BWPs. The first BWP and the second BWP have a same numerology.
What exactly they claim (claim 1)
1. A method of operating a communications device configured to transmit signals to and/or to receive signals from a wireless communications network, the method comprising: operating, by the communications device, in one of an idle state and an inactive state and, when operating in the one of the idle state and the inactive state, receiving, via a broadcasted signal from the wireless communications network, a configuration of at least two bandwidth parts (BWPs) for use by the communications device in transmitting signals to and/or receiving signals from the wireless communications network while remaining in the one of the idle state and the inactive state, the communications device, while remaining in the one of the idle state and the inactive state, adapting between the at least two BWPs, wherein radio resources forming a first of the BWPs at least partially overlap in both frequency and time with radio resources forming a second of the BWPs, and wherein the first BWP and the second BWP have a same numerology.
