Signaling protocol for a noisy communications channel |
August 27, 1996 |
| The retransmission of signaling messages that data terminals (e.g., modems) might exchange prior to exchanging user data is controlled by arranging a data terminal that receives multiple copies of the same signaling message so that it saves only the first copy thereof, but transmits a re |

Retransmission protocol for wireless communications |
August 22, 1995 |
| The throughput of a radio transmission link is enhanced by arranging a transmitter of data packets so that it responds to the transmission window closing by repeatedly retransmitting all unacknowledged data packets and doing so until the window reopens or a receiver status message ac |
