  • Patent number: 7954041
    Abstract: An apparatus and method are provided for transmitting a signal in a communication system using a low density parity check (LDPC) code. An LDPC codeword is generated by encoding an information word at a coding rate. A puncturing pattern is generated when a hybrid automatic repeat request (HARQ) scheme to be applied to the LDPC codeword is an incremental redundancy (IR) scheme. An additional pattern is generated when the HARQ scheme to be applied to the LDPC codeword is a partial chase combining (CC) scheme. A signal is transmitted by applying the puncturing pattern to the LDPC codeword at an associated coding rate when the HARQ scheme to be used is the IR scheme. A signal is transmitted by applying the additional pattern to the LDPC codeword at an associated coding rate when the HARQ scheme to be used is the partial CC scheme.

  • Patent number: 7953458
    Abstract: A method for controlling a sleep mode operation by a mobile station (MS) in a communication system. In the sleep mode operation control method, after entering a sleep mode, the MS transitions to an awake state in a listening interval. When there is data to transmit or receive to/from a base station (BS) in the awake state, the MS causes a neutral interval following the listening interval to transition to the awake state, and transmits or receives the data. The neutral interval is an interval where transition to the awake state and sleep state is available according to the data transmission/reception of the MS operating in the sleep mode.
