Apple patents method to wake phones faster for 5G messages
Apple describes a way for cell towers to send specific signals to phones that are in low-power mode. This helps the phone quickly sync with the network to receive important updates or messages.
In the filing’s own words
An example method for wireless communication includes: transmitting by a base station, to a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); transmitting the CSI-RS and TRS based on the transmitted resource information to the user device, wherein the user device has exited the reduced power state; determining whether there is paging information to transmit in a first physical downlink shared channel (PDSCH) transmission for the user device; transmitting a downlink control information message, wherein the downlink control information message is based on the determination that there is paging information for the user device, and wherein the user device has synchronized with the base station; and transmitting the first PDSCH transmission, based on the determination that there is paging information for the user device.
What exactly they claim (claim 1)
1. A method for performing a paging operation by a base station, comprising: transmitting a dedicated system information block (SIB) comprising resource information for receiving a tracking reference signal (TRS) by two or more user devices in a reduced power state; transmitting the TRS based on the transmitted resource information to a user device of the two or more user devices, wherein the user device exits the reduced power state to synchronize with the base station; transmitting a downlink control information message in a physical downlink control channel (PDCCH) to the user device; transmitting paging information in a physical downlink shared channel (PDSCH) transmission based on the downlink control information message; and establishing a Radio Resource Control (RRC) connection between the user device and the base station based on the paging information.
