20080240022 | Method for Allocating and Accessing Radio Resources in Ofdma System - Disclosed is a method for allocating and accessing downlink resources in the OFDMA communication system. In the resource allocation method, bursts having the same modulation and channel encoding level are arranged in a predetermined temporal order on a physical layer. Information on the allocated unit resources is included in a common control block and is transmitted to a subscriber station, and the subscriber station then detects a number of the allocated unit resources to thus check the range of bursts to be received by the subscriber station. Therefore, power consumption by the subscriber station is reduced and signaling overheads of the common control information and unneeded residual resources are decreased. | 10-02-2008 |
20080287138 | Method for Requesting and Reporting Channel Quality Information in Wireless System and Apparatus Thereof - The subscriber station of claim 15, wherein the uplink data includes data to be transmitted, and a header having information on the data and the subscriber, and the uplink data generator adds the subheader includDisclosed is a method and device for requesting and reporting channel quality information in a mobile communication system. An uplink radio resource for a subscriber station having data to transmit is allocated and a CQI indicator for requesting channel quality information is added to the allocation information to be transmitted to a subscriber station. The subscriber station having received the uplink radio resource allocation information generates channel quality information by measuring the radio channel quality for communication with the base station according to existence of the indicator and transmits desired uplink data having the generated channel quality information to the base station. As a result, the seamless and efficient channel quality report can be performed in the wireless communication system, and the optical modulation and the channel coding level can be adapted for the subscriber to transmit or receive the data corresponding to the channel quality. ing the channel quality information to the header of the uplink data. | 11-20-2008 |
20090067374 | Method for Traffic Indication and Channel Adaptation for Sleep Mode Terminals, and an Apparatus Thereof - The traffic indication and channel adaptation apparatus for a subscriber station in a sleep mode according to the present invention includes: a channel resource allocator for generating resource allocation information allocating an uplink channel resource to the subscriber station; a traffic indication and channel adaptation controller for generating a traffic indication message transmitted with the resource allocation information to the subscriber station, and providing a downlink data having a transmission level determined by applying an AMC level according to a CQI report message transmitted from the subscriber station; a transmitter for transmitting the uplink resource allocation information, the traffic indication message, and the downlink data to the subscriber station; and a receiver from receiving a CQI codeword or a CQI report message. | 03-12-2009 |
20090175178 | Method and apparatus for requesting and reporting channel quality information in mobile communication system - Disclosed is a method and device for requesting and reporting channel quality information in a mobile communication system. A base station a locates a dedicated feedback channel for channel quality information report to an uplink radio resource, transmits the allocation information to subscriber stations, and generates a CQI report message to request channel quality information from the subscriber stations. The subscriber stations receive the CQI report message from the base station, measures a radio channel quality for communication with the base station, generates channel quality information, generates a CQI response message including the channel quality information, and transmit-the CQI response message to the base station through a dedicates feedback channel designated in the allocation information. | 07-09-2009 |
20110305218 | METHOD FOR REQUESTING AND REPORTING CHANNEL QUALITY INFORMATION IN WIRELESS PORTABLE INTERNET SYSTEM - A method for requesting and reporting channel quality information (CQI) in a wireless portable Internet system is disclosed. Timing of a channel quality information request by a base station is determined, existence of an automatic repeat request acknowledgment (ARQ_ACK) message of downlink data is determined on requesting the channel quality information from the subscriber station, the automatic repeat request acknowledgment message and the radio resource for the channel quality report to the subscriber station is allocated, the automatic repeat request acknowledgment message and the channel quality report information is received, and a modulating and coding level of downlink data is determined by extracting the channel quality report information form the automatic repeat request acknowledgment message. | 12-15-2011 |

20130314373 | TOUCH DETECTING DEVICE USING SENSOR PAD SCRAMBLE - A capacitive type touch detecting device includes a first sensor pattern sub-group including a plurality of sensor pads, a second sensor pattern sub-group adjacent to the first sensor pattern sub-group in a second axis direction, a third sensor pattern sub-group adjacent to the first sensor pattern sub-group in the first axis direction, and a fourth sensor pattern sub-group adjacent to the second sensor pattern sub-group in the first axis direction. The sensor pads belonging to the first and third sensor pattern sub-groups are electrically connected, and the sensor pads belonging to the second and fourth sensor pattern sub-groups are electrically connected. A sequence in which the sensor pads belonging to the first and third sensor pattern sub-groups are connected is different from that in which the sensor pads belonging to the second and fourth sensor pattern sub-groups are connected. | 11-28-2013 |
20130314374 | TOUCH DETECTING DEVICE AND METHOD USING GROUP IDENTIFICATION - A capacitive type touch detecting device has one or more sensor pattern groups disposed in a row or column direction. A capacitive type touch detecting device for the sensor pattern groups is formed in a single layer, and thus it is possible to reduce production costs, and to simplify a manufacturing process. Further, the capacitive type touch detecting device requires a relatively smaller number of signal wires than a structure in which the signal wires are formed on the respective sensor pads, and thus a space for the signal wires can be minimized. | 11-28-2013 |
