Method and apparatus for time efficient retransmission using symbol accumulation
Abstract
The invention relates to a method and apparatus for data transmission comprising the steps of encoding a first set of data symbols to provide a first set of encoded symbols and a second set of encoded symbols; transmitting the first set of encoded symbols in a first frame; encoding a second set of data symbols to provide a third set of encoded symbols; determining whether the first frame failed to decode; determining a minimum retransmission power level for the second set of encoded symbols if the first frame failed to decode; and transmitting the second set of encoded symbols and the third set of encoded symbols in a second frame if the first frame failed to decode. Efficient transmission of data is achieved by determining a minimum retransmission power level in the event transmitted encoded symbols fail to decode.

Tandbergs Patentkontor AS, 0306 Oslo (54) Description Radio communication with time-saving transmission by collecting characters / symbols (57) Summary Effective transmission of data by means of symbol accumulation, where data packets received with errors are sent again at a lower level for the energy per digit, but simultaneously with a new data packet and in the same sequence or frame as this one. A receiving site, which may be a stationary station (6) on a communication network, receives the data transmission and retransmission, demodulates the signals, and separates the received data into a new and a retransmitted packet. Then, the energy of the transmitted packet is accumulated with the energy already accumulated for the packets received with errors, after which the accumulated packet is decoded, all at the destination. The accumulation gene of the additional energy provided by the subsequent transmissions improves the likelihood of proper decoding. The transmission capacity can then be improved since packets received with errors are re-transmitted together with the main transmission of the new data packet. The capacity is brought to a maximum since the transmission of the packet that was first received with errors occurs at a lower energy level than in the transmission of the new packet.
