Abstract: An out-of-service recovery search method includes establishing a frequency list including at least one searchable frequency, searching a suitable cell of a network according to the frequency list when the user terminal is in an out-of-service state, determining at least one first skip condition of the user terminal, performing a full-band power scan mechanism for scanning received signal strength indication (RSSIs) of user terminal supported frequency bands when the at least one first skip condition of the user terminal is absent and no suitable cell of the network is searched within the searchable frequency of the frequency list, skipping the full-band power scan mechanism when the at least one first skip condition of the user terminal is present and no suitable cell of the network is searched within the searchable frequency, and performing an RSSI sniffer for scanning a signal power of each frequency of the searchable frequency.

Abstract: According to at least one aspect, a communication system is provided. The communication system includes a power amplifier configured to amplify an input signal to generate an amplified output signal and provide the amplified output signal to an antenna, a power supply coupled to the power amplifier and configured to provide power to the power amplifier based on a power supply control signal, and a controller coupled to the power supply. The controller is configured to identify a target transmit power level for transmission of a wireless signal, generate the power supply control signal based on the target transmit power level using information indicative of a relationship between the target transmit power level and a setting of the power supply, generate performance information indicative of a characteristic of the communication system when the wireless signal is transmitted, and update the information indicative of the relationship using the performance information.
