| 20090262671 | APPARATUS AND METHOD FOR ALLOCATING UPLINK RESOURCES IN A WIRELESS COMMUNICATION SYSTEM - An apparatus and a method for allocating an uplink resource in a wireless communication system that uses a Half duplex-Frequency Division Duplex (H-FDD) scheme. The apparatus includes a controller and a message generator. The controller determines a resource allocation scheme enabling an F-FDD mobile station to allocate uplink bursts to a first group and a second group using one MAP message. The message generator generates a MAP message indicating the resource allocation scheme determined by the controller. | 10-22-2009 |
| 20090274227 | APPARATUSES AND METHODS FOR TRANSMISSION AND RECEPTION IN A CODEBOOK BASED CLOSED-LOOP (CL)-MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) SYSTEM - Apparatuses and methods for transmission and reception in a Closed-Loop (CL)-Multiple Input Multiple Output (MIMO) system are provided. A codebook generation method includes determining weight vectors v | 11-05-2009 |
| 20100014462 | METHOD AND APPARATUS FOR RECOGNIZING MULTICAST AND BROADCAST SERVICE REGION IN BROADBAND WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for recognizing a Multicast and Broadcast Service (MBS) region in a broadband wireless communication system are provided. In the method, whether a next MBS MAP message transmission point of a first frame and an MBS data burst transmission point indicated by MBS burst assignment information of a second frame match with each other in a third frame is determined. When matching with each other in the third frame, a control message including information for determining a starting point of an MBS region is generated. The generated control message is transmitted during one of the first and second frames. | 01-21-2010 |
| 20110090884 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING SYSTEM INFORMATION IN BROADBAND WIRELESS COMMUNICATION SYSTEM - An apparatus and method for transmission/reception of system information in a broadband wireless communication system are provided. An operation of a Base Station (BS) in a broadband wireless communication system includes determining whether to apply a system configuration corresponding to a previous value of a Secondary-Super Frame Header (S-SFH) change count changed according to update of system information and, when applying the system configuration corresponding to the previous value of the S-SFH change count, setting a parameter representing the applied system configuration to a first value and, when applying a system configuration corresponding to a current value of the S-SFH change count, setting the parameter to a second value, and transmitting a Primary-Super Frame Header (P-SFH) including the S-SFH change count and the parameter set to the first value or the second value. | 04-21-2011 |
| 20110093757 | METHOD AND APPARATUS FOR HANDLING ERRORS IN A SYNCHRONOUS UL HARQ PROCESS - An apparatus and method for handling an error that may occur during a HARQ process are provided. The method includes determining that an UpLink (UL) HARQ burst has been transmitted on a first resource, determining if the UL HARQ burst has been received, determining if the first resource for UL HARQ burst transmission needs to be changed, and transmitting feedback information regarding receipt of the UL HARQ burst and whether the first resource needs to be changed. | 04-21-2011 |
| 20110110301 | APPARATUS AND METHOD FOR TRANSMITTING SIGNAL IN WIRELESS COMMUNICATION SYSTEM - An apparatus and a method for transmitting control information in a small base station of a wireless communication system are provided. In the method, when the small base station operates in a Low Duty operation Mode (LDM) in a superframe, a control signal including LDM operation information is generated. Only a subframe via which a preamble, a control signal including the LDM operation information, and a SuperFrame Header (SFH) are transmitted is transmitted during the superframe. When the small base station operates in a normal operation mode in a superframe, at least one of the control information and data is transmitted via at least one subframe of the superframe. | 05-12-2011 |
| 20110296270 | Apparatus and method for resource segmentation in wireless communication system - An apparatus and a method segment an allocated resource in data transmission in a wireless communication system. When a size of transmission data is large, the data information bit is distributed to one or more forward error correction (FEC) blocks with consideration of a size of the data information bit. A number of data tones is determined based on control information with respect to each of the one or more FEC blocks. The data information bit distributed to the one or more FEC blocks is mapped into a data tone with consideration of the number of data tones determined for each of the one or more FEC blocks. | 12-01-2011 |
| 20110305214 | APPARATUS AND METHOD FOR CAPABILITY NEGOTIATION FOR HYBRID AUTOMATIC REPEAT REQUEST PARAMETER IN BROADBAND WIRELESS COMMUNICATION SYSTEM - A technique for supporting newly defined Hybrid Automatic Repeat reQuest (HARQ) categories without an occurrence of an interpretation error when using a legacy Mobile Station (MS) and a legacy Base Station (BS) in a broadband wireless communication system is provided. A method of transmitting a capability negotiation message includes determining an HARQ parameter set to be allocated, setting a value of a second field for informing whether to indicate an HARQ parameter set which corresponds to an index greater than a maximum value that can be indicated by using a first field for indicating an index of the HARQ parameter set, and transmitting the capability negotiation message including the second field. | 12-15-2011 |
