Abstract
A method is provided a wireless system for reliably transmitting context information in robust header compression at low signal energies. More particularly, the methodology of the invention provides an elongated virtual Transmission Time Interval (Super TTI) for the first few (in particular, the first) non-compressed packet (that includes upper layer headers) of a packet stream transmitted using ROHC compression. Improved reception reliability for the uncompressed packet, in particular to decode the headers, results by application to the Super TTI of a combination of TTI Bundling techniques, RLC segmentation and association with multiple HARQ processes and use of enough HARQ rounds.
