20160022578 | POLYPEPTIDE BASED BLOCK COPOLYMER AND THE PROCESS FOR THE PREPARATION THEREOF, AND THE POLYMER MICELLES USING THE SAME - The present disclosure relates to a polypeptide based block copolymer having biodegradability due to peptidase, and a process for the preparation thereof, and polymer micelles using the same. The block copolymer according to the present disclosure is a block copolymer of a polyethylene glycol-based compound having properties such that the solubility for water is different depending on the pH, but cannot form micelles due to a self-assembly phenomenon; and a polyglutamic acid-based compound formed using an aminolysis reaction of glutamic acid and tertiary amine in which the end of one alkyl group is substituted with NH | 01-28-2016 |
20150117300 | METHOD FOR TRANSMITTING DOWNLINK SIGNAL AT A RELAY NODE IN A WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR - A method for transmitting downlink signals at a source base station in a wireless communication system is disclosed. The method comprises transmitting a downlink signal to an end user and at least one relay; receiving a negative response signal from the end user; receiving a positive response signal and channel status information about a channel between the at least one relay and the end user, wherein the at least one relay overhears the negative response signal; and scheduling a specific relay having the best channel status of the at least one relay to re-transmitting the downlink signal to the end user. | 04-30-2015 |
