Patent number: 8855639Abstract: A handover performing method and a method of allocating a connection identifier (CID) at the time of handover are disclosed. The method includes transmitting a handover request message to a serving base station, and receiving a handover response message including CID update information used in a target base station from the serving base station. At this time, the CID update information may include a transport CID (TCID) allocation start position and a TCID allocable value used in the target base station. Accordingly, it is possible to minimize service delay of a mobile station by providing a method of updating the CID of the mobile station for performing fast handover.Type: GrantFiled: November 24, 2008Date of Patent: October 7, 2014Assignee: LG Electronics Inc.Inventors: Ae Ran Youn, Ki Seon Ryu, Hee Jeong Cho, Tae Gon Kong

Patent number: 8798087Abstract: A group scheduling method, a method for selectively receiving information elements according to group scheduling, and a Mobile Station (MS) are provided. The group scheduling method schedules allocation of resources to a plurality of mobile stations by dividing the plurality of mobile stations into at least one group. The group scheduling method includes enabling an index element in a group index corresponding to a group to which a mobile station (MS) scheduled to transmit data belongs and placing a group allocation information element including the group index at the beginning of a MAP. In this method, group scheduling information is transmitted to MSs using a group allocation IE to prevent the MSs from reading unnecessary information transmitted every frame, thereby reducing power consumption of the MSs.Type: GrantFiled: December 2, 2008Date of Patent: August 5, 2014Assignee: LG Electronics Inc.Inventors: Ae Ran Youn, Hee Jeong Cho, Tae Gon Kong

Patent number: 8738982Abstract: A data processing method and a data re-transmission method in a broadband wireless access system are disclosed. A transmitting side generates a coded block set including coded blocks of a predetermined number and the coded blocks are transmitted to first and second base stations. The transmitting side sets a timer after transmitting a last coded block of the coded blocks. The coded blocks received by the second base station are transmitted to the first base station, and the transmitting side receives a control signal indicating whether there is a transmission error from the first base station.Type: GrantFiled: April 18, 2008Date of Patent: May 27, 2014Assignee: LG Electronics Inc.Inventors: Tae Gon Kong, Yong Ho Kim
