20110090858 | METHOD AND APPARATUS FOR ALLOCATING COMMUNICATION RESOURCES USING VIRTUAL CIRCUIT SWITCHING IN A WIRELESS COMMUNICATION SYSTEM AND METHOD FOR TRANSMITTING AND RECEIVING DATA IN A MOBILE STATION USING THE SAME - A method and apparatus using Virtual Circuit Switching (VCS) in a new scheme are provided for allocating and employing resources by combining Circuit Switching (CS) and Packet Switching (PS), in which a base station allocates resources of a dedicated channel using the CS to a user and then transmits data on the dedicated channel. When data is not transmitted to the user, the base station allocates the allocated dedicated channel resources for resources of a shared channel and transmits data of a different user. Therefore, system capacity can be increased and a waste of communication resources can be minimized in a wireless communication system for frequently transmitting a small amount of traffic that is sensitive to a delay time. | 04-21-2011 |
20110188399 | APPARATUS AND METHOD FOR ALLOCATING RESOURCES IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS MOBILE COMMUNICATION SYSTEM - A method for receiving resources allocated from a base station by a terminal in an OFDMA mobile communication system. The method includes receiving, for a data channel, a number of first components, which indicates an amount of resources used with a first resource allocation scheme, and a number of second components, which indicates an amount of resources used with a second resource allocation scheme, from the base station over a common control channel; determining first and second identifier lengths of channel elements for the first and second resource allocation schemes according to the number of first components and the number of second components; receiving resource allocation information including an identifier indicating at least one channel element allocated to the terminal, over a data control channel using one of the identifier lengths; and transmitting and receiving data over a resource of a channel element indicated by the received identifier. | 08-04-2011 |
20130208687 | APPARATUS AND METHOD FOR PERFORMING RESOURCE ALLOCATION AND COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM, AND SYSTEM USING SAME - Methods and apparatus are provided for transmitting and receiving uplink data in a wireless communication system. Hopping-related information is received at a mobile station from a base station. Resource allocation information is received at the mobile station from the base station. The uplink data is transmitted from the mobile station to the base station through at least one resource determined based on a sequence for global hopping and a sequence for local hopping, if global hopping and local hopping are enabled | 08-15-2013 |

20100095182 | Apparatus and method for transmitting/receiving broadcast data in a mobile communication system - A method and apparatus for transmitting a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ) are provided. The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval. | 04-15-2010 |
20100111211 | Apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas - An apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas are provided. A receiver estimates a fading channel of received data, selects a weight set relative to a maximum data transmission rate from at least one weight set with elements of a plurality of orthogonal weight vectors, and transmits feedback information including the selected weight set and channel-by-channel state information to a transmitter. The transmitter demultiplexes data to be transmitted on a basis of the feedback information into at least one sub-data stream, multiplies each sub-data stream by an associated weight, and transmits the data. | 05-06-2010 |

The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval. | 09-02-2010 |
20110235540 | TRANSMISSION/RECEPTION APPARATUS AND METHOD FOR SUPPORTING MIMO TECHNOLOGY IN A FORWARD LINK OF A HIGH RATE PACKET DATA SYSTEM - Methods and apparatus are provided for transmitting and receiving data in a communication system with a plurality of antennas. Data and a first pilot are generated. The first pilot is transmitted at a first position in a frequency domain that corresponds to a position of the generated data in the frequency domain and at a first position in a time domain that is with the generated data, in every transmission time interval of the data. A second pilot is generated. The second pilot is transmitted at predetermined second positions in the time domain and the frequency domain, in a transmission time interval that is predefined by a transmitter and a receiver. | 09-29-2011 |
20140307615 | Apparatus and Method for Transmitting/Receiving Multiuser Packet in a Mobile Communication System - An apparatus and method is provided for generating one packet with transmission data and transmitting the packet from an access network transceiver system (ANTS) to a plurality of access terminals (ATs) in a mobile communication system including the ATs and the ANTS which are capable of performing packet data communication with ATs located in coverage thereof. The method includes the steps of generating a medium access control (MAC) header including information on a receiving AT's address, a length and format for transmission data, generating a MAC payload, by consecutively connecting data units to be transmitted to the receiving AT, and generating a MAC trailer. The ANTS pads ‘0’ bits to the MAC header if a predetermined MAC size is greater than a sum of lengths of the MAC header, the MAC payload and the MAC trailer. | 10-16-2014 |
