Patent KR-20100028124-A (KR)
Title: Cellular mobile communication system
Inventor: ISHIKURA KATSUTOSHI
IPC: H04B1/707
Filed: 2006-07-31
Abstract: A cellular mobile communication system has a problem that communication quality is lowered by increase of an attenuation amount of a desired signal and increase of an interfering signal amount at a position apart from a base station and high-speed data communication becomes difficult. To solve this problem, when a mobile station M is at a location D where the radio attenuation is small, the mobile station M uses an OFDM signal to transmit data x, y, z via a traffic channel all at once so that data communication is performed at the maximum communication speed. On the other hand, when the mobile station M moves from the location D to a location E which is far from any of the base stations A, the mobile station M divides B, C, the data x, y, z into three and, by using a diffusion OFDM signal having a high interference resistance, increases the interference resistance, and transmits data x, y, z almost simultaneously from the three base stations A, B, C, thereby realizing equivalence of high-speed data transmission.

Title: Methods and apparatus for successive interference cancellation based on rate capping in peer-to-peer networks
Inventor: LI JUNYI
IPC: H04B1/10
Filed: 2008-07-06
Abstract: In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation (SIC). The first receiver device receives a first transmission request from a first transmitter device indicating that the first transmitter device intends to transmit traffic to the first receiver device. Similarly, the first receiver device receives a second transmission request from an interferer second transmitter device. The first receiver device then determines a transmission rate cap for the interferer second transmitter device based on the signal strengths of the first and second transmission requests and sends it to the interferer second transmitter device. The transmission rate cap is a maximum rate at which the first receiver device can reliably decode traffic signals from the second transmitter device.

Title: Methods for the identification of polypeptide antigens associated with disorders involving aberrant cell proliferation and compositions useful for the treatment of such disorders
Inventor: LEVINSON ARTHUR D
IPC: G01N33/68
Filed: 2002-09-04
Abstract: Methods and compositions for the development of effective cancer therapies using mitotic inhibitors which have limited general toxicity to normal, non-cancerous cells and tissues are provided. The methods and compositions utilize cytotoxic compounds comprised of a cell-binding agent (e.g., antibodies) conjugated to an anti-mitotic compound (e.g., maytansinoids). The invention further provides antibodies which are substantially incapable of inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC), thereby ensuring that the therapeutic effect is mediated primarily by the anti-mitotic component of the cytotoxic compound, rather than by indirect cell killing via ADCC and/or CDC. The antibodies of the invention further are capable of differentiating between polypeptide antigens which are more highly expressed on proliferating cancer cells as compared to proliferating non-cancer cells.
