Abstract:
1. A method for providing an acknowledgement (ACK)/negative acknowledgement (NACK) report from a first radio node to a second radio node, comprising: the first radio node transmitting over a radio channel data blocks to the second radio node; the second radio node receiving a signal from the first radio node; detecting that some data blocks are correctly received and some data blocks are not correctly received; generating an ACK/NACK message identifying correctly received data blocks as void and not correctly received data blocks as NACKed, where void means that no ACK/NACK information is provided such the second radio node does not confirm in the ACK/NACK message that a data block is correctly received from the first radio node; the second radio node sending the ACK/NACK message to the first radio node; the first radio node receiving and decoding the ACK/NACK message and setting the data blocks identified as NACKed to be retransmitted by the first radio node; and the first radio node transmitting the data blocks set to be re-transmitted to the second radio node, wherein the first radio node's determination of which data blocks to re-transmit is independent of a round trip time (RTT) associated with the first radio node sending a block, the second radio node receiving the data block, the data block being processed to determine if it is correctly received, generation of an ACK/NACK message for that data block, transmitting the ACK/NACK message, and receiving the ACK/NACK message at the first radio node.
