Patent ID: 8711832

Claim:
A method for controlling decoding to save power of a modem chip in a wireless communication system, comprising the steps of: measuring a Signal-to-Noise Ratio (SNR) of a radio signal received from a base station at a current time; determining format information of a packet to be received based on a total number of slots occupied by the packet to be received; determining, according to at least one of the format information and the measured SNR, a threshold number of slots of the packet to be received before decoding the packet, the threshold being less than the total number of slots occupied by the packet; determining whether to decode a received data associated with the packet by comparing the threshold with a number of received slots of the packet; storing the received data without decoding when the number of received slots is determined to be less than or equal to the threshold; and decoding the received data to recover the packet when the number of received slots is determined to be greater than the threshold.
