Abstract
An apparatus and method for controlling decoding in a wireless communication system are provided. Data is received in a slot associated with a packet to be received. A threshold is determined according to format information of the packet. It is determined whether to decode the received data by comparing the threshold with the number of slots received in relation to the packet. The received data is stored without decoding, if the number of the received slots is less than or equal to the threshold. The received data is decoded to recover the packet, if the number of the received slots is greater than the threshold.
Claims12
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.
An apparatus for controlling decoding to save power of a modem chip in a wireless communication system, comprising:
- a threshold decider for 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, and determining, according to at least one of the format information and the 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;
- a control signal generator for determining whether to decode a received data by comparing the threshold with a number of received slots of the packet and generating a control signal according to a result of the determination;
- and
- a decoder for 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.
