| 20110007673 | Method and Apparatus for Acquiring Resource Allocation of Control Channel - A method of acquiring a resource allocation of a control channel includes acquiring a resource region of the control channel in a second subframe based on a first resource allocation of the control channel, acquiring a resource region of a second downlink channel in the second subframe based on the resource region of the control channel, and receiving a second resource allocation of the control channel on a third downlink channel in the second subframe. The third downlink channel is indicated by the second downlink channel. | 01-13-2011 |

| 20100027446 | Method of Transmitting Scheduling Information In TDD System - A method of transmitting scheduling information in time-division-duplex(TDD) system is provided. The method comprises configuring a radio frame, the radio frame comprising at least one downlink subframe and at least one uplink subframe, wherein a downlink subframe is reserved for downlink transmission and an uplink subframe is reserved for uplink transmission, and transmitting scheduling information on a downlink control channel in a downlink subframe, the scheduling information comprising an uplink indicator and uplink resource assignment, the uplink indicator indicating which at least one uplink subframe the uplink resource assignment is valid for. Data can be efficiently transmitted by using an uplink indicator which indicates a specific location of a subframe. | 02-04-2010 |
| 20110216713 | Method Of Transmitting Scheduling Request Signal - A method of transmitting a scheduling request signal, wherein the scheduling request signal is used to request a radio resource for uplink transmission in a wireless communication system is provided. The method includes configuring a physical uplink control channel (PUCCH) for transmission of a scheduling request signal in a subframe, the subframe comprising two consecutive slots, a slot comprising a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols, the scheduling request signal being carried by a presence or absence of transmission of the PUCCH, wherein at least one SC-FDMA symbol is assigned for transmission of a sounding reference signal, and transmitting the scheduling request signal and the sounding reference signal in the subframe. Scheduling request signal can be transmitted without interference with other control signals such as sounding reference signal that are transmitted on the same control channel with the scheduling request signal. | 09-08-2011 |

| 20100008435 | METHOD FOR TRANSMITTING ACK/NACK SIGNAL AND METHOD FOR ESTABLISHING THE SIGNAL TRANSMISSION - A method for transmitting an ACK/NACK signal and a method for establishing the signal transmission are disclosed. A system for the method determines whether the ACK/NACK signal is repeatedly transmitted or not according to channel environments of a user, and transmits the ACK/NACK signal according to the determined result within a single TTI. Areas unused for transmitting the ACK/NACK signal are allocated for data, resulting in an increased reception reliability of the ACK/NACK signal. | 01-14-2010 |

| 20090209247 | METHOD FOR TRANSMITTING AND RECEIVING CONTROL INFORMATION THROUGH PDCCH - A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions. | 08-20-2009 |

| 20120033650 | FLEXIBLE ALLOCATION OF CONTROL SIGNAL RESOURCES - A wireless communication system is disclosed. The method for processing a downlink subframe at a user equipment in a wireless communication system includes receiving information associated with a PHICH duration, receiving a subframe that includes a PHICH, a PDCCH, and a PDSCH, and obtaining the PDSCH after a lapse of the PDCCH duration. If the PHICH duration is larger than the PDCCH duration, the obtaining of the PDSCH is performed in consideration of PHICH resources in a duration that corresponds to the PHICH duration but not to the PDCCH duration. | 02-09-2012 |
