Data transmission method combating degradation of the quality of service
First Claim
1. A system for transmitting data over a physical resource, comprising:
- a first layer configured to manage the physical resource and to guarantee a quality of service;
a first sub-layer configured to supply a transmission support in accordance with the quality of service and to segment the data into transmission units, the first sub-layer reducing a size of at least one of the transmission units when transmission conditions on the physical resource are degraded;
a second sub-layer configured to transmit at least one of the transmission units over the physical resource during each of transmission time intervals, the transmission time interval being a periodic time interval during which the second sub-layer is allowed to access the physical resource; and
a physical layer configured to perform error correction coding or decoding of the data, whereinthe first layer guarantees the quality of service by assigning a set level to the ratio of received signal power to noise plus interference,in the case of degradation of the transmission conditions the transmission power of a transmitter is increased so as to maintain the quality of service, andthe size of each of the transmission units is reduced when the transmission power reaches a maximum value.

Abstract
A system for transmitting data over a physical resource including a layer configured to manage the physical resource and to guarantee a quality of service, and a first sub-layer configured to supply a transmission support in accordance with the quality of service and to segment the data into transmission units. The first sub-layer reduces a size of at least one of the transmission units when transmission conditions on the physical resource are degraded. A second sub-layer is configured to transmit at least one of the transmission units over the physical resource during each of transmission time intervals. The transmission time interval is a periodic time interval during which the second sub-layer is allowed to access the physical resource. A physical layer is configured to perform error correction coding or decoding of the data.
