Controlling data transmission rate on the reverse link for each mobile station in a dedicated manner
Patent number: 7898952Abstract: The data transmission rate on the reverse link in a mobile communications system is controlled by determining an interference level at a base station due to signals from all mobile stations served by the base station, and determining a transmission energy level required for each mobile station. The interference level is compared with the transmission energy level to obtain a comparison result for each mobile station, and each mobile adjusts its data transmission rate based upon the comparison result, which is sent via a common channel on a forward link to each mobile station in a dedicated manner. Thereafter, packet data is transmitted on the reverse link in accordance with the adjusting so that data throughput can be maximized.Type: GrantFiled: February 26, 2007Date of Patent: March 1, 2011Assignee: LG Electronics Inc.Inventors: Ki Jun Kim, Young Cho Kim, Young Jo Lee, Jong Hoe An, Young Woo Yun, Young Jun Kim -

Patent number: 7308104Abstract: Disclosed are a forward multiple scrambling code generating method and apparatus in a communication system. Each base station uses primary scrambling codes and an associated one of secondary scrambling code sets, each consisting of a plurality of secondary scrambling codes. When an n-th one of the primary scrambling codes is to be generated, an initial value of the scrambling code generator is set with a binary value of “n,” so that a desired primary scrambling code is generated using the initial value. When an n-th one of the secondary scrambling codes in an m-th one of the secondary scrambling code sets is to be generated, an initial value of the scrambling code generator is set with a value obtained by shifting the n-th primary scrambling code by m times, thereby generating a desired secondary scrambling code.Type: GrantFiled: August 15, 2000Date of Patent: December 11, 2007Assignee: LG Information & Communications, Ltd.Inventors: Ki Jun Kim, Young Jo Lee, Young Cho Kim

Patent number: 6820231Abstract: Disclosed is a method of transmitting data in a communication system. A receiving part determines an optimum data transmission rate in accordance with the change of the channel environment of the receiving part, and provides the determined data transmission rate to a transmitting part. The transmitting part processes the data to be transmitted according to the transmitted optimum data transmission rate, and transmits the processed data to the receiving part. The transmitting part applies a different data coding rate or modulation type to the data to be transmitted in accordance with the determined data transmission rate. Since the optimum data transmission rate is determined in accordance with the change of the channel environment of the receiving part, an improved data throughput and re-transmission probability can be obtained with a reduced delay. Also, the insufficiency of memory capacity in the receiving part can be solved.Type: GrantFiled: May 30, 2001Date of Patent: November 16, 2004Assignee: LG Electronics Inc.Inventors: Young Jo Lee, Young Cho Kim
