The method includes: configuring the common control information to be received by a mobile station belonging to the second communication system; and transmitting the common control information through the resource allocation area for the second communication system included in one of the uplink sub-frame and the downlink sub-frame. | 09-11-2008 |
| 20080279143 | METHOD FOR SUPPORTING SHORT LATENCY DATA TRANSMISSION IN A MOBILE COMMUNICATION SYSTEM - A method for supporting short latency data transmission in a mobile communication system is provided. A frame is divided into an uplink subframe and a downlink subframe. Each of the uplink and downlink subframes includes at least one zone for the short latency data transmission and each of the at least one zone includes a first channel for indicating data resource assignment, a second channel over which to transmit data, or a third channel for feedback signal reception. The method includes indicating a location and a size of the second channel using the first channel included in any one of the at least one zone by a transmitting end, transmitting data over the second channel, and receiving feedback information for the data, which has been transmitted over the second channel, over the third channel. | 11-13-2008 |
| 20080291884 | System and method for transmitting/receiving signal in communcation system - A system and method are disclosed for transmitting/receiving a signal in a communication system in which a first communication system and a second communication system coexist, the second communication system being evolved from the first communication system and being capable of using a control signal and a broadcast signal used in the first communication system. The method of transmitting a signal includes the steps of transmitting a first message including common control information and frame control information for the first communication system in a first frame, transmitting a second message including common control information and frame control information for the second communication system in a second frame, and signaling location information of the transmitted second message in the second frame. | 11-27-2008 |
| 20090196367 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING REFERENCE SIGNAL IN A COMMUNICATION SYSTEM - An apparatus and method for transmitting/receiving a reference signal in a communication system are provided, in which a transmitter determines first and second different transmit power values for first and second pilot tones residing in one of the substantially same time resource and the substantially same frequency resource among pilot tones included in a data area in a subframe having time and frequency resources, and transmits the first pilot tone with the first transmit power value and the second pilot tone with the second transmit power value. The first transmit power may be a reference transmit power value and the second transmit power may be a product between a weight and the reference transmit power value. | 08-06-2009 |

The method includes performing a subband-based permutation on resources for composing a subchannel; selecting one or more subbands as resources for a band selection subchannel from the resources passing through the subband-based permutation; composing the band selection subchannel using at least one of the selected subbands; performing a resource allocation unit based permutation on resources not selected for the band selection subchannel; composing a resource allocation unit based diversity subchannel using subband remained in the selected subbands after the band selection subchannel is composed and at least one of the resource allocation units of the resources passing through the resource allocation unit based permutation; and composing a tone-based diversity subchannel by performing a tone-based permutation on resources remained after the resource allocation unit based diversity subchannel is composed. | 09-10-2009 |
| 20100227638 | METHOD AND APPARATUS FOR POWER CONTROL IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus for power control in a wireless communication system are provided. A Mobile Station (MS) operation method for power control in a wireless communication system includes assigning an UpLink (UL) control channel to the MS from a Base Station (BS), determining a location to receive a Transmit Power Control (TPC) command based on the UL control channel, and receiving a TPC command in the determined location and increasing or decreasing transmit power, thus advantageously being capable of reducing an overhead for power control command assignment information. | 09-09-2010 |
| 20100329201 | METHOD AND APPARATUS FOR TRANSMITTING PAGING CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting paging control information in a wireless communication system are provided. A method of operating a Base Station (BS) for paging in a superframe-based wireless communication system includes determining a paging listening interval, determining an interval of at least one or more subframes before the paging listening interval, as a paging control listening interval, and, during the paging control listening interval, broadcasting a paging control message. | 12-30-2010 |
| 20110053626 | Resource allocation apparatus and method for reducing overhead in mobile communication system - A method and apparatus change resource allocation to reduce overhead in a mobile communication system. The method of operating a base station for changing a fixed resource allocation to reduce overhead in a mobile communication system includes determining whether a plurality of fixed resource allocations collide in a fixed resource allocation period. If the fixed resource allocations collide, at least one fixed resource allocation among the plurality of fixed resource allocations is cancelled in the fixed resource allocation period and a determination is made on whether to reallocate the at least one fixed resource allocation before a next fixed resource allocation period. If the at least one fixed resource allocation is reallocated before the next fixed resource allocation period, a control message containing reallocation information changed with respect to the at least one fixed resource allocation is transmitted to a corresponding mobile station. Accordingly, a location of an allocation resource region based on a fixed resource allocation can be effectively changed by using minimum control information. | 03-03-2011 |
| 20110110339 | APPARATUS AND METHOD FOR ALLOCATING RESOURCE USING CODEBOOK BASED ON RESOURCE SIZE AND BURST SIZE IN BROADBAND WIRELESS COMMUNICATION SYSTEM - An apparatus and method for allocating resources by using a codebook based on a resource size and a burst size in a broadband wireless communication system are provided. A method of operating a Mobile Station (MS) includes receiving a group configuration message from a Base Station (BS), wherein the group configuration message includes an N-bit first bitmap for indicating that M resource sizes are supported in the group among N resource sizes supported for group resource allocation, where M is less than N, and receiving a group resource allocation message from the BS, wherein the group resource allocation message includes a second bitmap for indicating a size of a resource allocated to a corresponding MS among MSs for which resource allocation is determined. | 05-12-2011 |
