Abstract
The present disclosure relates to A method of a user equipment, UE, the method comprising: receiving data of a multicast, from an access network node, using a repeat request process when the UE is in a radio resource control, RRC, connected state; transitioning into an RRC inactive state; and receiving the multicast, from the access network node, when the UE is in the RRC inactive state; wherein the UE uses the same repeat request process used to receive the multicast in the RRC connected state to receive data of the multicast when the UE is in the RRC inactive state.

1-26. (canceled)
A method performed by a mobile device, the method comprising:
- keeping, with an access network node, a service continuity for multicast reception by using a multicast radio bearer (MRB) configured as downlink (DL) only Radio Link Control-Unacknowledge Mode (RLC-UM) entity for point-to-multipoint (PTM) transmission during transition between a Radio Resource Control (RRC) inactive state and a RRC connected state, wherein
- a Protocol Data Convergence Protocol (PDCP) count value on the mobile device corresponding to the MRB is maintained during the transition between the RRC inactive state and the RRC connected state.
A method of an access network node, the method comprising:
- keeping, with a mobile device, a service continuity for multicast reception by using a multicast radio bearer (MRB) configured as downlink (DL) only Radio Link Control-Unacknowledge Mode (RLC-UM) entity for point-to-multipoint (PTM) transmission during transition of the mobile device between a Radio Resource Control (RRC) inactive state and a RRC connected state, wherein
- a Protocol Data Convergence Protocol (PDCP) count value on the mobile device corresponding to the MRB is maintained during the transition between the RRC inactive state and the RRC connected state.
A mobile device comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to keep, with an access network node, a service continuity for multicast reception by using a multicast radio bearer (MRB) configured as downlink (DL) only Radio Link Control-Unacknowledge Mode (RLC-UM) entity for point-to-multipoint (PTM) transmission during transition between a Radio Resource Control (RRC) inactive state and a RRC connected state, wherein
- a Protocol Data Convergence Protocol (PDCP) count value on the mobile device corresponding to the MRB is maintained during the transition between the RRC inactive state and the RRC connected state.
