A number of RBs to be occupied by a data burst to be transmitted is determined. A first variable indicative of a number of mini frames to be occupied by the data burst is determined based on a resource amount corresponding to the number of RBs and an available resource amount of the mini frame. A second variable is determined based on the number of RBs and the first variable. MAP is transmitted that includes the first variable, the second variable, and information indicating RBs where a resource is allocated in a mini frame first located in a time domain among the mini frames to be occupied by the data burst.Type: GrantFiled: June 19, 2009Date of Patent: January 1, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Young-Bo Cho, Hee-Won Kang, Seong-Hyeon Chae

Patent number: 8316270Abstract: An apparatus and a method for supporting an HARQ scheme in a wireless communication system are provided. In a method for operating a base station, whether a resource used for a system of a different standard and a resource used for one of an HARQ reply and an HARQ retransmission packet by a synchronous HARQ scheme collide with each other is estimated. A collision packet ID is allocated to an HARQ subburst corresponding to one of an HARQ reply and an HARQ retransmission packet estimated to collide, and an offset of the one of the HARQ reply and the HARQ retransmission packet is changed. A MAP message including at least one of the collision packet ID, and changed offset information is generated. The MAP message is transmitted.Type: GrantFiled: April 16, 2009Date of Patent: November 20, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Seong-Hyeon Chae, Hee-Won Kang, Young-Bo Cho
