Digital cellular telecommunications system (Phase 2+); Rate adaption on the Mobile Station - Base Station System (MS-BSS) interface (V10.0.1; 3GPP TS 44.021 version 10.0.1 Release 10)
"The present document defines the rate adaptation functions to be used in PLMN Mobile Stations (MS)s for adapting terminal interface data rates to the Mobile Station - Base Station System (MS-BSS) interface data rates in accordance with 3GPP TS 43.010 [3]. The provision of these functions will depend on the services a particular station is designed to support. NOTE 1: The present document should be considered together with 3GPP TS 48.020 [9] (Rate Adaptation on the BSS-MSC Interface) to give a complete description of PLMN rate adaptation. NOTE 2: The Gb interface does not play any role in the scope of the present document although the term ""A/Gb mode"" is used."
