Inventor: ITO TAKUMI
IPC: H04L1/02
Filed: 2005-02-14
Abstract: It is possible to provide a reception device capable of demodulating a signal with a very simple configuration. The reception device (1) includes N reception antennas (11-1 to 11-N). Each of the reception antennas (11-1 to 11-N) receives a signal. A channel coefficient estimation device (12) estimates a channel coefficient from the signal received by each of the reception antennas (11-1 to 11-N) and outputs it. A QR decomposition device (13) performs QR decomposition by inputting a channel matrix having channel coefficients as elements and outputs Q matrix and R matrix. A QH operation device (14) multiplies the complex conjugate transposed matrix of the Q matrix by inputting the Q matrix and the reception signal and outputs converted signal z. A transmission sequence estimation device (15) inputs the converted signal z and the R matrix and estimates the transmission sequence. ® KIPO & WIPO 2007

Title: Communication apparatus and method for supporting fast handover transparent to mobile station
Inventor: JANG HEE JIN

Filed: 2007-03-16
Abstract: An access router and a method for processing handover by using the same are provided to minimize the loss of data, of which destination is a mobile station, during handover of the mobile station, thereby reducing the latency of the handover. In order to buffer data to be transmitted an MS(Mobile Station) during a handover of the MS, a pAR(previous Access Router) establishes a tunnel with at least one access router, nAR(new Access Router) adjacent to the pAR. If it is determined that the MS moves or will move from the pAR to the nAR, the pAR buffers the data to be transmitted to the MS(414). The MS moves from the pAR to the nAR(413). When the MS requests authentication to the nAR, an authentication process with respect to the MS is performed through the nAR and an AAA(Authentication, Authorization, and Accounting) server(416,417). When sensing that the MS moves to the nAR, the nAR identifies a previous access router of the MS by comparing a MAC(Media Access Control) address of the MS with a MAC address of the MS, which is received from the pAR. The nAR transmits a HO-Completed message to the identified access router, the pAR(418). The pAR receiving the HO-Completed message identifies data, of which destination is the MS, from the buffered data, referring to the identifier of the MS included in the HO-Completed message. The pAR transmits the identified data to the nAR(419). The nAR transmits the received data to the MS(420).

Title: A method for transmitting and receiving data in a communication system
Inventor: CHOI JIN GHOO
IPC: H04L1/00
Filed: 2007-04-04
Abstract: A method and an apparatus for transmitting/receiving data in a communication system are provided to obtain user multiplexing effect by allowing a multicast or single user to use extra power. A terminal requests joining from a base station providing a multicast service, and joins a corresponding multicast group after authentication. When the terminal successfully receives a certain number of frames continuously, it transmits a flag bit to the base station(410) because there is a high probability that there is a user who has a channel gain worse than that of the terminal, and transitions to a non-feedback state(415). If the number of successful receptions of frames is smaller than the certain number, the terminal remains in a feedback state and feeds back its CQI(Channel Quality Indication) to the base station.
