Abstract:
A system and a method for transmitting and receiving data in a communication system are provided to minimize the power consumption of an MS(Mobile Station) by using a downlink scheduling scheme and an uplink power control scheme when the MS is in a battery shortage state. An MS in a dormant or idle state compares its residual battery capacity with a preset threshold. If it is confirmed that the residual battery state is smaller than or equal to the preset threshold(405), the MS transmits a MOB_LBAT_IND(Mobile Lack Battery Indication) message to a BS(Base Station)(407). Receiving the MOB_LBAT_IND message, the BS judges that the MS is in a battery shortage state(409), and transmits a MOB_LBAT_ACK(Mobile Lack Battery Acknowledgement) message to the MS(411). Receiving the MOB_LBAT_ACK message, the MS transits to the battery shortage state(413).
