20090310553 | MOBILE STATION, BASE STATION, AND METHOD FOR UPLINK SERVICE - The present invention relates to a mobile station, a base station, and a method for an uplink service that provides a high-speed data service between the base station and the mobile station in a wireless communication system. A method for providing an uplink service in a mobile station includes, after TCP data are received from a base station, measuring a partial round trip time which is a time until ACK which is a response to the received TCP data is inputted into an uplink transmission MAC buffer, transmitting information on the measured partial round trip time to the base station, receiving resource allocation information—unicast resource allocation information for transmitting the ACK to the base station in the mobile station—from the base station, and transmitting the ACK of the TCP data received from the base station on the basis of the resource allocation information to the base station. | 12-17-2009 |
20100111045 | BASE STATION AND METHOD FOR PROVIDING UPLINK SERVICE - A method for providing uplink service from a base station to a terminal includes: transmitting information on a TCP packet and a dedicated code to a terminal; receiving a code number from the terminal using the dedicated code; searching a requesting bandwidth for the code number and allocating resources to the terminal; and receiving the ACK packet for the TCP packet through the allocated resources from the terminal. | 05-06-2010 |
20100284332 | METHOD FOR TRANSMITTING AND RECEIVING DATA IN MULTI CARRIER WIRELESS ACCESS SYSTEM - There is provided a method in which a base station transmits downlink data in a wireless access system supporting multi-carriers. The method comprising negotiating with a terminal about a sleep mode parameter including information on a sleep window and a listening window, if the terminal is operating in a sleep mode, transmitting information on a carrier used for data transmission among the multi-carriers to the terminal through at least one of a medium access control (MAC) header, a MAC control message, and a control channel and transmitting data to the terminal based on the information during the listening window. Accordingly, waste of radio resources can be prevented by making efficient use of the multi-carriers even though the terminal is operating in the sleep mode. | 11-11-2010 |
20100285831 | METHOD OF PERFORMING HANDOVER IN MULTI CARRIER WIRELESS ACCESS SYSTEM - There is provided a method for handover of a terminal in a wireless access system using multi-carrier operation. The method comprises: receiving a handover command message from a serving base station; and performing network reentry to a target base station based on the handover command message, wherein the handover command message includes information required for handover to the target base station and information on whether the target base station supports handover using multi-carriers. Accordingly, it is possible to efficiently perform the handover in the wireless access system supporting the multi-carriers. | 11-11-2010 |
20100331018 | TERMINAL, METHOD FOR MANAGING THEREOF, BASE STATION AND METHOD FOR MANAGING THEREOF - A method for managing a terminal operated in an idle state is provided. The method includes entering a femto cell, determining whether a femto base station managing the femto cell has the same paging group as a macro base station managing a macro cell overlapping the femto cell, transmitting a first ranging code triggering a paging enable state to the femto base station if it is determined that the paging group is the same as the determination result, and receiving a paging message from the femto base station. | 12-30-2010 |
20110149898 | APPARATUS AND METHOD FOR MANAGING MULTI-CARRIER - An apparatus for managing a multi-carrier in a communication system supporting the multi-carrier receives channel quality information of multi-carriers from a terminal and directs the terminal to change a primary carrier from a current primary carrier to one carrier of the multi-carriers on the basis of reference information including channel quality information. | 06-23-2011 |
20110216684 | MULTI-CARRIERS MANAGING DEVICE AND METHOD AND SLEEP MODE OPERATING METHOD OF TERMINAL - A multi-carriers management device of a communication system supporting multi-carriers requests a terminal attempting to enter a sleep window to change a primary carrier, and transmits a control message to the terminal through the changed primary carrier during the sleep window. | 09-08-2011 |
20120106516 | METHOD AND APPARATUS FOR TRANSMITTING NEIGHBOR BASE STATION INFORMATION PERFORMED BY MACRO BASE STATION IN WIRELESS COMMUNICATION SYSTEM - Provided is a method for requesting neighbor base station information by user equipment in a wireless communication system. The method includes: searching neighbor base stations targeted for a handover; transmitting a list request message including preamble information about a neighbor base station searched by the user equipment among the neighbor base stations and a neighbor base station list request indicator indicating a request for information about the neighbor base station to a serving base station; and receiving a list response message including an identification information and system information of the neighbor base station from the serving base station. | 05-03-2012 |
20120108238 | METHOD FOR OPERATION OF FEMTO BASE STATION BASED ON RADIO ACCESS SYSTEM - A method for opearation of femto base station (BS) is provided. The method includes: transmitting the first low duty operation (LDO) pattern information, which includes length information of an available interval (AI) where the femto BS is activated and length information of an unavailable interval (UAI) where the femto BS is inactivated, to user equipment (UE) and operating based on the first LDO pattern where the first LDO cycle, a sequence of the AI and the UAI, is repeatedly arranged. The first LDO pattern information further including a superframe offset as information for leading a start point of the first LDO cycle. | 05-03-2012 |
20120113943 | HANDOVER METHOD IN WIRELESS COMMUNICATION SYSTEM - Disclosed is a method of a handover in a wireless communication system. The method includes transmitting a handover request message to the service BS, and receiving a handover command message from the service BS in response to the handover request message. Multi-carriers are assigned to a terminal in advance right before a handover, and all or some of the multi-carriers are activated right after the handover. Therefore, multi-carrier are effectively utilized. | 05-10-2012 |
20120115481 | METHOD FOR PROVIDING AND RECEIVING RELIABLE SERVICE IN WIRELESS COMMUNICATION SYSTEM - A method for providing reliable wireless service in a femto system is provided. The method includes broadcasting information about out-of-service, which notifies that an air interface based on the femto BS is disabled, to user equipment (UE); and disabling the air interface. The information about the out-of-service comprising an identifier about a recommended BS that is another BS which the UE can enter. | 05-10-2012 |
20120176985 | METHOD OF UPDATING SYSTEM INFORMATION IN WIRELESS COMMUNICATION SYSTEM - The present invention provides a method of a Base Station (BS) updating system information using a superframe structure in a wireless communication system, comprising transmitting a primary header including system scheduling information pertinent to an update of the system information and transmitting an updated secondary header. The system scheduling information comprises secondary header change state information indicating a change state of the updated secondary header, secondary header applying information indicating whether the secondary header change state information is applied to a current system, and a secondary header change indicator indicating the updated secondary header. | 07-12-2012 |
