A method of transmitting at least one data stream using superposition coding (SPC) in a wireless communication system is disclosed. More specifically, a method includes receiving feedback information from at least two access terminals (ATs), assigning the at least two ATs as a first AT or a second AT based on the feedback information, wherein the first AT has a smaller path loss than that of the second AT, and the second AT has a larger path loss than that of the first AT, channel coding the at least one inputted data stream by a channel coding scheme, modulating the at least one data stream using layered modulation scheme, allocating wireless resources to symbols of the first AT and the second AT, and transmitting the symbols to at least one of the first AT and the second AT according to the allocated wireless resources.

A method of transmitting and receiving data using superposition modulation in a wireless communication system having multiple antennas is disclosed. More specifically, the method comprises encoding the at least one inputted data stream by a channel coding scheme, puncturing the at least one inputted coded data stream into at least two sub-streams, layer-modulating the at least two sub-streams using layer-modulation schemes, transmitting the layered-modulated sub-streams via the multiple antennas, wherein transmission power of each antenna is based channel condition, and receiving by at least one user the layered-modulated sub-stream, wherein the each user uses different demodulation scheme.

A method of transmitting data by at least one access terminal (AT) in a wireless communication system is disclosed. More specifically, the method includes ceasing all transmissions by the at least one AT during a duration corresponding to a duration used by an access node (AN) to transmit a superframe preamble, wherein the superframe comprises a plurality of physical frames.
摘要:
A method and apparatus for randomizing access probes from co-located mobile terminals in order to reduce collisions is provided. By each mobile terminal or group of mobile terminals computing a random delay between a minimum delay value and a maximum delay value and using the random delay to delay the starting time of access probes, collisions between access probes from different mobile terminals may be reduced.

A method for receiving data at different frequencies includes receiving a first transmission packet including data at a first carrier frequency, and receiving a second transmission packet comprising data at a second carrier frequency. The method further includes maintaining communication with transmission entities which transmit the first and second transmission packets, and identifying reception quality of the first and second transmission packets. In addition, a method for retransmitting subpackets includes transmitting a first subpacket of a packet transmission from at least two transmitting entities. Upon receiving a non-acknowledgement NACK generated responsive to the first subpacket, the method further includes alternating transmission of subsequent subpackets from different transmitting entities. Upon receiving an acknowledgement ACK generated responsive to any subpackets of the packet transmission, the method further includes transmitting a first subpacket of a new packet transmission.

A method of receiving an acknowledgement (ACK) signal from at least one access terminal (AT) in a wireless communication system is disclosed. More specifically, the method includes transmitting at least one packet via a packet data channel from an access network (AN), receiving at least one ACK signal from the at least one AT using same channelization resources, wherein each AT is assigned a code specific to each AT, and identifying the ACK signal corresponding to the transmitted packet from the received at least one ACK signal.

A method of executing to battery power consumption between an access terminal (AT) and an access network (AN) in a wireless communication system is disclosed. More specifically, the method includes transmitting a notification message to the AN, receiving a confirmation message from the AN, and entering the power-saving mode according to the determined power saving mode. Here, the notification message includes at least one of battery life information and a power-saving mode request, and the confirmation message includes a determined power saving mode which is based on the at least one of battery life information and the power-saving mode request.
