Abstract
During data transmission to a remote unit (113) utilizing a supplemental, high-speed data channel (105), data transmission stops due to all data being communicated to the remote unit (113) or because of an interruption in transmission. In the situation where all data has been transmitted to the remote unit (113) the remote unit (113) will drop the supplemental channel (105) prior to acknowledging reception of the last frames transmitted, and acknowledgment will take place utilizing the low-speed fundamental channel (103). In the situation where an interruption occurs, data transmission will continue utilizing a fundamental channel (103) if less than a predetermined amount of data remains to be transmitted.
Claims18
A method for data transmission within a broad-band communication system, the method comprising the steps of:
- transmitting data utilizing a second channel and a second encoding scheme;
- receiving an interruption in the transmission of data utilizing the second channel and the second encoding scheme;
- ceasing transmission of the data utilizing the second channel and the second encoding scheme;
- and
- continuing transmission of the data utilizing a first channel and a first encoding scheme.
A method for data transmission within a broad-band communication system, the method comprising the steps of:
- transmitting data utilizing a second channel and a second encoding scheme;
- determining when a plurality of data has been transmitted;
- ceasing transmission of the data utilizing the second channel and the second encoding scheme when the plurality of data has been transmitted;
- and
- receiving an acknowledgment of reception of the plurality of data;
- and
- re-transmitting the plurality of data utilizing a first channel and a first encoding scheme based on the acknowledgment.
A method for data transmission within a broad-band communication system, the method comprising the steps of:
- determining that a data transmission needs to take place utilizing a second channel;
- determining if the second channel is available;
- and
- transmitting data utilizing a first channel and a first encoding scheme when the second channel is unavailable, otherwise transmitting data utilizing the second channel and a second encoding scheme when the second channel is available.
An apparatus for data transmission within a broad-band communication system, the apparatus comprising:
- supplemental channel circuitry outputting data over a high-speed second channel with a second encoding scheme;
- a controller outputting an indication to stop transmission of data over the second channel with the second encoding scheme;
- and
- fundamental channel circuitry outputting the data over a first channel with a first encoding scheme when the data output over the high-speed second channel has been stopped.
