A multicast data packet is received from a base station through a downlink multicast transmission channel. If the multicast data packet has never been successfully decoded before, the multicast data packet is decoded and the success/failure in decoding the multicast data packet is determined. Upon the failure in decoding the multicast data packet, a NACK signal indicating the failure in decoding the multicast data packet is generated with sequences, the number of which is equal to the number of antennas of the user terminal. The NACK signal is transmitted to the base station through a shared feedback channel. If the user terminal has at least two antennas, sequences corresponding to the at least two antennas are orthogonal to each other and constitute sequence signals. | 09-16-2010 |

20090103437 | Method of transmitting/receiving data in sensor network for reducing overhearing of sensor nodes - Provided is a method of transmitting/receiving data in a sensor node for reducing overhearing of sensor nodes, and a sensor network which implements the method. A sender node having transmission data from among a plurality of nodes which perform a low power listening (LPL) operation in an asynchronous manner at predetermined time intervals, generates a long preamble including short preambles, each having information including a destination address of the transmission data, a remainder of the long preamble, and a length of the transmission data, and sequentially transmits the second preamble and the transmission data. A receiver node from among the plurality of nodes determines whether a valid signal is sensed during an active state in the LPL operation. If it is determined that the valid signal is sensed, the receiver node receives the short preamble transmitted from the sender node. The receiver node determines a duration time of a deactivated state of the receiver node based on the received first preamble, thereby reducing overhearing in the sensor network. | 04-23-2009 |
