| 20090097447 | METHOD AND APPARATUS FOR ALLOCATING RESOURCES OF A CONTROL CHANNEL IN A MOBILE COMMUNICATION SYSTEM USING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING - A method is provided for allocating resources of a control channel in a mobile communication system using Orthogonal Frequency Division Multiplexing (OFDM). The method includes, when a time index and a frequency index of available Resource Elements (REs) are defined as l and k, respectively, dividing the available REs in a two-dimensional structure of (k, l); and time-first-allocating each RE to a plurality of RE groups while increasing the time index l for each frequency index k from an initial value up to a predetermined range. | 04-16-2009 |
| 20100322174 | METHOD AND APPARATUS FOR A MOBILE SELECTION BASED INITIAL ACCESS SCHEME IN A MULTICARRIER SYSTEM - A method and apparatus for initial access of a mobile device in multi-carrier system. A base station transmits initial access resource information about the entire system band to the mobile device through a specific carrier to which the mobile device tries initial access. The mobile device determines an uplink initial access band by using received initial access resource information. The base station enables initial access through a predefined downlink response band. | 12-23-2010 |
| 20110038303 | METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING CONTROL CHANNEL - A method and apparatus for transmitting/receiving control channels through a wireless backhaul in an OFDM-based communication system including relay nodes is provided. A method for transmitting a control channel includes arranging control resources for at least one receiver; sorting the control resources and null resources in a control channel region; rearranging the control resources to be distributed and the null resources to be adjacent to the distributed control resources; and mapping the control resources and null resources to the control channel region. | 02-17-2011 |
| 20110044391 | METHOD AND APPARATUS FOR CONFIGURING CONTROL CHANNEL IN OFDM SYSTEM - A control channel configuration method and apparatus is provided for supporting Inter-Cell Interference Coordination (ICIC) in an OFDM-based communication system. The control channel configuration method includes determining a Resource Block (RB) to be used for configuring control channels; configuring the control channels by mapping the control channels in a data channel region within the RB; and transmitting the configured control channels, wherein configuring the control channels includes mapping the control channels in units of Resource Element Groups (REGs) formed by binding one or more Resource Elements (REs) in a time domain-preferred allocation manner within the same RB. | 02-24-2011 |
| 20110085506 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING MULTI-USER CONTROL CHANNELS IN A WIRELESS COMMUNICATION SYSTEM WITH MULTIPLE ANTENNAS - Provided are a method and apparatus for transmitting and receiving multi-user control channels through a data channel region in a wireless communication system using multiple antennas. Further provided is a definition of a new search space for control channel candidates. In the transmitting method, a base station forms control channels for a plurality of user equipment each of which is composed of at least one resource block, performs a mapping for the control channels by dividing a space of the same transmission region in a data channel region of a sub-frame, and then multiplexes the control channels with data channels in the data channel region of the sub-frame and to transmit the multiplexed control channels. | 04-14-2011 |
| 20110243059 | APPARATUS AND METHOD FOR INTERLEAVING DATA IN A RELAY PHYSICAL DOWNLINK CONTROL CHANNEL (R-PDCCH) - A wireless network comprising a first base station operable to communicate with mobile stations and a plurality of relay stations for providing bi-directional communication between the first base station and a plurality of mobile stations. The first base station transmits a relay physical downlink control channel (R-PDCCH) in the downlink to the plurality of relay stations. The R-PDCCH comprises: i) a first search space comprising downlink (DL) grants associated with the plurality of relay stations; and ii) a second search space comprising uplink (UL) grants associated with the plurality of relay stations. | 10-06-2011 |
| 20110249582 | CHANNEL STATE INFORMATION REQUEST/FEEDBACK METHOD AND APPARATUS - A Channel State Information (CSI) request/feedback method and apparatus for a wireless communication system supporting carrier aggregation or bandwidth extension are provided. A base station sets a CSI request field of an Uplink (UL) grant for scheduling UL transmission on a UL Component Carrier (CC) corresponding to a Downlink (DL) CC of which CSI is requested, to a request value. The UL grant is transmitted to a terminal. | 10-13-2011 |
| 20110249633 | METHOD OF TRANSMITTING AND RECEIVING CONTROL INFORMATION BASED ON SPATIAL-MULTIPLEXING GAIN - A control information transmission and reception method based on a spatial-multiplexing gain, are provided. The control information may be transmitted by obtaining the spatial-multiplexing gain using an E-PDCCH region, and thus, a transmission efficiency of the control information may be improved. The common control information used for decoding the E-PDCCH may be transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information. Information associated with an indicator indicating whether the E-PDCCH is to be used during a subsequent resource allocation period may be transmitted, and thus, whether decoding with respect to the E-PDCCH is to be performed during the subsequent allocation period may be determined. | 10-13-2011 |
