Patent number: 9356739Abstract: A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.Type: GrantFiled: February 17, 2014Date of Patent: May 31, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Johan Torsner, Janne Peisa, Maria Edvardsson, Christer Edholm, Erik Dahlman, Stefan Parkvall
