Patent number: 8437317Abstract: A wireless communication system including transmitters for determining a transmission rate for an associated receiver according to channel state information fed back from associated receivers, and transmitting packets at the determined transmission rate. In a communication method, a transmitter groups packets to be transmitted to the receivers according to transmission rates, and generates frames configured by packets with an identical transmission rate. The transmitter aggregates frames with different transmission rates into one transmission burst, and sends the transmission burst. The data communication method based on packet aggregation can efficiently manage resources by determining transmission rates for reception stations (STAs) on the basis of feedback channel state information in a transmission STA, aggregating packets to be transmitted to the reception STAs to form a packet group, and transmitting packet groups with different transmission rates using one multi-rate aggregation (MRA) burst.Type: GrantFiled: September 9, 2005Date of Patent: May 7, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Hun Jang, Jong-Ae Park, Dong-Jun Lee, Jin-Bong Chang, Young-Soo Kim

Patent number: 8416809Abstract: Disclosed is a receiver for configuring a Block Acknowledgement (BA) frame in a wireless communication system for acknowledgement of a data transmission from a transmitter. The receiver receives a Block Acknowledgement Request (BAR) frame in the data transmission from the transmitter and determines an overall size of a bitmap for the BA frame from the BAR frame to acknowledge the data transmission. The receiver configures the BA frame of the response to include the bitmap having the determined overall size, and transmits the configured BA frame to the transmitter. The bitmap of the BA frame includes bits representing reception results of packets of the data transmission received from the transmitter.Type: GrantFiled: September 16, 2009Date of Patent: April 9, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Hun Jang, Jong-Ae Park, Dong-jun Lee, Jin-Bong Chang, Yoong-Soo Kim

Patent number: 8068476Abstract: A method is provided for efficiently allocating a transmission period in a wireless network system. An access point (AP) transmits a PSMP frame indicating a downlink period provided to each station (STA) and a minimum amount of an uplink period allocated to each STA, and at least one sub PSMP frame indicating an uplink period additionally provided for an STA that transmitted a resource request message for remaining queued data in the uplink period indicated by the PSMP frame. If the uplink period indicated by the PSMP frame is insufficient to transmit the queued data, the STA transmits a data unit including a part of the queued data and a resource request message for the remaining queued data in the uplink period. After transmitting the resource request message, the STA receives the sub PSMP frame after the full period indicated by the sub PSMP frame, and transmits the remaining queued data to the AP in the uplink period indicted by the sub PSMP frame.Type: GrantFiled: October 17, 2006Date of Patent: November 29, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Hun Jang, Jong-Ae Park, Dong-Jun Lee, Young-Soo Kim, Hyo-Sun Hwang
