Radio acces bearer support enhancements
The present document is a technical report that summarises the work on the UTRAN Release 2000 work item "Radio Access Bearer Support Enhancements". The work items comprises of five areas of study:
1) Robust header compression
2) PDCP multiplexing
3) Variable Iu frame formats and unequal error protection over Uu
4) Channel type switching per logical channel
5) Header removal
Each study area includes the requirements of the proposed feature, a description of the basic mechanism and a discussion of the issues involved. A recommended solution is provided and impacts to other RAN WGs are analysed.
