Abstract: An apparatus and a method for transmitting/receiving a signal in a MIMO(Multiple Input Multiple Output) mobile communication system are provided to control a MIMO scheme adaptively in consideration of initial transmission and retransmission when the MIMO mobile communication system uses an HARQ(Hybrid Automatic Repeat reQuest) scheme. A controller(123) determines an HARQ scheme to be used for a transmission signal, and determines a MIMO scheme to be used for the transmission signal correspondingly to the determined HARQ scheme. An encoder encodes the transmission signal according to the determined HARQ scheme. A mapper(115) maps a signal output from the encoder according to the determined MIMO scheme. A transmitter(119) transmits a signal output from the mapper. If the determined HARQ scheme is an IR(Incremental Redundancy) scheme, the controller determines the MIMO scheme to be an SM(Spatial Multiplexing) scheme. If the determined HARQ scheme is a CC(Chase Combining) scheme, the controller determines the MIMO scheme to be an STTD(Space Time Transmit Diversity) scheme.

Abstract: PURPOSE: A method for detecting and controlling an ink level in an ink jet printer is provided to utilize residual ink by checking an amount of ink remaining in an ink cartridge when the ink level in the ink cartridge drops below a predetermined level. CONSTITUTION: A method for detecting and controlling an ink level in an ink jet printer includes the steps of detecting the ink level in an ink cartridge(S10) and checking whether the ink level in the ink cartridge is below a predetermined level(S20). If the ink level in the ink cartridge is below the predetermined level, a line print is carried out(S30) and a printing density is detected(S40). Then, the detected printing density is compared with a reference printing density(S60). If the detected printing density is lower than the reference printing density, a minute ink level is calculated(S70). Then, it is determined whether the calculated minute ink level requires a printing density compensation algorithm(S80).
