COOPERATIVE TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method, apparatus, and computer program for cooperative transmission are provided. A re-transmitter for a data packet determined as not having been received at a re- ceiver correctly is selected amongst the potentialre- transmitters in a cooperative transmission mode. In more detail, the re-transmitter is selected amongst an original transmitter of the data packet and assisting transmitters configured to assist transmission of the original transmit- ter. The assisting transmitters receive the data packet in the original transmission, unless errors occur in the reception at a given assisting transmitter, and are candidates for the retransmission in case the original transmission results in erroneous reception at the receiver.
