20100091902 | METHOD OF TRANSMITING DATA TO MITIGATE INTRERENCE - A method of transmitting data using hybrid automatic repeat request (HARQ) is provided. The method includes transmitting an initial data, receiving a retransmission request for the initial data, generating a retransmission data by shifting the phase of the initial data on signal constellation and transmitting the retransmission data. Inter-cell interference or intra-cell interference can be mitigated. | 04-15-2010 |
20100208673 | Method of Allocating Resource in Wireless Communication System - A method of allocating resources in a wireless communication system includes allocating a plurality of physical resource blocks, each of which includes a plurality of sub-parts, to a virtual resource block, and mapping the virtual resource block to the plurality of physical resource blocks, wherein the virtual resource block is mapped to the sub-parts located in different positions in the range of each physical resource block. The number of resource elements allocated for the virtual resource block is constantly maintained. | 08-19-2010 |
20100208678 | Method of Transmitting Data Based on Adaptive Modulation and Coding - A method of transmitting data is provided. The method includes generating a frame, the frame comprising a data burst, a submap and a map wherein the submap indicates a resource allocation state of the data burst, and the map indicates a differential adaptive modulation and coding (AMC) level for the submap, and transmitting data using the frame, wherein the differential AMC level is information on change in an AMC level applied to the submap comparing with other submap in a different frame. High-speed data transmission is realized and limited radio resources can be more efficiently used. | 08-19-2010 |
20100208779 | Transmitter for Reducing Channel Selectivity - A transmitter for reducing time selectivity and/or frequency selectivity in a wireless communication system includes a plurality of transmit antennas, a phase shifter which is disposed for each transmit antenna and is configured to shift a phase of data transmitted through the transmit antenna by a phase shift value, and a channel selectivity processor configured to obtain the phase shift value by using a channel phase value fed back from a receiver. | 08-19-2010 |
20100211842 | METHOD OF TRANSMITTING DATA USING CONSTELLATION REARRANGEMENT - A data retransmission method using hybrid automatic repeat request (HARQ) includes transmitting a data block, receiving a retransmission request signal for the data block, generating a retransmission block by performing swapping or inversion between bits constituting the data block according to the retransmission request signal, and transmitting the retransmission block. | 08-19-2010 |
20100254342 | METHOD OF ALLOCATING RESOURCES IN WIRELESS COMMUNICATION SYSTEMS - A method of allocating resources in a wireless communication system includes dividing an available frequency band on a logical plane into a distributed zone and a localized zone, dividing the distributed zone into a plurality of subparts in time domain, and dividing the distributed zone and the localized zone into a distributed zone and a localized zone on a physical plane. The plurality of subparts included in one distributed zone on the logical plane is mapped to a different distributed zone on the physical plane. | 10-07-2010 |
20110194502 | METHOD FOR TRANSMITTING VOIP PACKET - A method for transmitting a voice over Internet protocol (VoIP) packet includes allocating a radio resource for VoIP packet transmission to a user, transitioning a VoIP service from a talk period, in which the VoIP packet is transmitted using the radio resource, to a silence period in which the VoIP packet is not transmitted, releasing the radio resource during the silence period, and transitioning the VoIP service to the talk period by reallocating the radio resource. Limited radio resources can be further effectively used. | 08-11-2011 |
20110207496 | METHOD AND DEVICE FOR DATA TRANSMISSION IN MULTIPLE CARRIER WAVE SYSTEM - Provided are a method and a device for data transmission in a multiple carrier wave system. With respect to a carrier wave that includes a first guard band, a data band, and a second guard band on a frequency domain, at least one guard physical resource unit (guard PRU) is allocated to at least one of said first guard band and said second guard band, said guard PRU is mapped to a contiguous resource unit (CRU), and data are transmitted via the CRU to which said guard PRU is mapped. The CRU to which said guard PRU has been mapped is mapped to a contiguous logical resource unit (CLRU). The index of the CRU to which said guard PRU has been mapped and the index of the CRU to which the PRU of said data band has been mapped may be continuous. | 08-25-2011 |
