3GPP44.060General Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 17TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The MAC procedures defined in this sub-clause are applicable in packet transfer mode. They are applicable in dual transfer mode, if both the network and the mobile station support DTM.

The procedures in this sub-clause (clause 8) shall not be used to change the frequency allocation of the carrier supporting the dedicated resources for the mobile station in dual transfer mode. None of the PACKET DOWNLINK ASSIGNMENT, the MULTIPLE TBF DOWNLINK ASSIGNMENT, the PACKET UPLINK ASSIGNMENT, the MULTIPLE TBF UPLINK ASSIGNMENT, the PACKET TIMESLOT RECONFIGURE or the MULTIPLE TBF TIMESLOT RECONFIGURE messages shall include frequency parameters for the carrier supporting the dedicated resources when they are sent to a mobile station in dual transfer mode.

NOTE: The network may use the DTM procedures on the main DCCH (the DTM ASSIGNMENT COMMAND message), if the radio resources for the RR connection and one or more TBF(s) need to be changed (see 3GPP TS 44.018).
