SYSTEMS AND METHODS FOR RETRANSMISSION WITH ON-LINE RECONFIGURATION
First Claim
1. A method implemented in a transmitter of a digital subscriber line (DSL) system, comprising the steps of:
- encoding a data stream into a plurality of first frames according to a framing configuration;
obtaining a request for an on-line reconfiguration of the framing configuration from a receiver;
suspending the encoding of the data stream into the first frames in response to the request;
retransmitting at least one of the first frames to the receiver during a retransmission time period that commences relative to the suspending of the encoding of the data stream into the first frames;
resuming the encoding of the data stream into a plurality of second frames according to a modified framing configuration consistent with the on-line reconfiguration; and
transmitting the second frames to the receiver upon expiration of the retransmission time period.

Abstract
Disclosed are various embodiments for performing retransmission with on-line reconfiguration. A data stream is encoded into first frames according to a framing configuration. A request is obtained for an on-line reconfiguration of the framing configuration from a receiver. The encoding of the data stream into the first frames is suspended in response to the request. One or more first frames are retransmitted to the receiver during a retransmission time period that commences relative to the suspending of the encoding of the data stream into the first frames. The encoding of the data stream into second frames is resumed according to a modified framing configuration consistent with the on-line reconfiguration. The second frames are transmitted to the receiver upon expiration of the retransmission time period.

15. A system, comprising:
a transmitter for transmitting a data stream over a communications channel to a receiver, the transmitter comprising; a framing encoder configured to encode the data stream into a plurality of frames according to a framing configuration; and reconfiguration logic that performs an on-line reconfiguration of the communications channel, the reconfiguration logic comprising; logic that suspends operation of the framing encoder according to the framing configuration; logic that enables retransmission of at least one of the frames encoded according to the framing configuration during a retransmission state that commences relative to the operation of the framing encoder being suspended; logic that resumes operation of the framing encoder according to a modified framing configuration consistent with the on-line reconfiguration; and logic that disables transmission of frames encoded according to the modified framing configuration until the retransmission state ends. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A system, comprising:
a receiver for receiving a data stream over a communications channel from a transmitter, the receiver comprising; logic that transmits a request for an on-line reconfiguration of the communications channel to the transmitter; logic that obtains at least one retransmitted frame of the data stream from the transmitter after the request is transmitted, the at least one retransmitted frame being framed according to a first framing configuration; logic that obtains an indication that signals that the on-line reconfiguration is to take effect in a predefined number of discrete multi-tone (DMT) symbols, wherein no initially transmitted frames of the data stream are obtained before the on-line reconfiguration takes effect after obtaining the indication; and logic that obtains at least one frame of the data stream from the transmitter when the on-line reconfiguration takes effect, the at least one frame being framed according to a second framing configuration that is consistent with the on-line reconfiguration. - View Dependent Claims (25, 26, 27)
