摘要:
A method of transmitting or receiving uplink signals in a wireless communication system and an apparatus therefor are provided. In one aspect of the method of transmitting the uplink signals, a base station determines whether each of user equipments uses an orthogonal frequency division multiple access (OFDMA) scheme or a single carrier-frequency division multiple access (SC-FDMA) scheme in uplink transmission. Further, the base station transmits scheduling information containing information regarding the determined multiple access scheme to the user equipments, and thus reports a multiplexing scheme to be used by each user equipment. In addition, each user equipment transmits the uplink data to the base station by multiplexing the uplink data by using the OFDMA scheme or the SC-FDMA scheme according to the scheduling information.

A cogeneration system including an engine, which drives a generator to generate electricity, a cooling/heating unit, which includes at least one compressor, a four-way valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, to establish a heat pump type refrigerant cycle, and a refrigerant over-heating unit to supply heat of cooling water used to cool the engine to a suction-side refrigerant line of the compressor of the cooling/heating unit, and to supply heat of exhaust gas discharged from the engine to the suction-side refrigerant line of the compressor and to a discharge-side refrigerant line of the compressor. In accordance with the cogeneration system, it is possible to maximize absorption of the waste heat of the engine while preventing compressor malfunction, and thus, to increase the refrigerant condensing temperature of the indoor heat exchanger. Thus, an enhancement in heating performance is achieved.
