Abstract
A method of multicast data delivery in a radio resource control (RRC) inactive state includes receiving, by a user equipment (UE) in an RRC connected state, an RRC release message indicating transitioning of the UE from the RRC connected state to an RRC inactive state and receiving, while in the RRC inactive state, multicast data in response to joining a multicast group and receiving multicast configuration parameters.
Claims20
A method of multicast data delivery in a radio resource control (RRC) inactive state, comprising the steps of:
- receiving, by a user equipment (UE) in an RRC connected state, an RRC release message indicating transitioning of the UE from the RRC connected state to an RRC inactive state;
- and
- receiving, while in the RRC inactive state, multicast data in response to joining a multicast group and receiving multicast configuration parameters,
- wherein the multicast configuration parameters are conveyed in the RRC release message and comprise a first set of parameters for multicast reception in the RRC connected state and a second set of parameters for multicast reception in the RRC inactive state, the second set of parameters including paging occasion information and semi-persistent scheduling information for multicast reception in the RRC inactive state.
A method of multicast data delivery in a radio resource control (RRC) inactive state, comprising the steps of:
- receiving, by a user equipment (UE) in an RRC connected state, an RRC release message indicating transitioning of the UE from the RRC connected state to an RRC inactive state;
- and
- receiving, while in the RRC inactive state, multicast data in response to joining a multicast group and receiving multicast configuration parameters;
- wherein, while in the radio resource control (RRC) inactive state and after receiving the RRC release message, the user equipment (UE):
- joining the multicast group;
- or
- receiving the multicast configuration parameters, or both:
- wherein joining the multicast group, while the user equipment (UE) is in the radio resource control (RRC) inactive state, occurs based on a random access process,
- wherein receiving the multicast configuration parameters, while the user equipment (UE) is in the radio resource control (RRC) inactive state, occurs based on the random access process, and
- wherein receiving the multicast configuration parameters, while the user equipment (UE) is in the radio resource control (RRC) inactive state, occurs based on a message B (MsgB) of a two-step random access process or a message 4 (Msg4) of a four-step random access process.
A method of multicast data delivery in a radio resource control (RRC) inactive state, comprising the steps of:
- receiving, by a user equipment (UE) in an RRC connected state, an RRC release message indicating transitioning of the UE from the RRC connected state to an RRC inactive state;
- and
- receiving, while in the RRC inactive state, multicast data in response to joining a multicast group and receiving multicast configuration parameters;
- wherein, while in the radio resource control (RRC) inactive state and after receiving the RRC release message, the user equipment (UE):
- joining the multicast group;
- or
- receiving the multicast configuration parameters;
- or
- both;
- and
- wherein joining the multicast group, while the user equipment (UE) is in the radio resource control (RRC) inactive state, occurs based on a configured grant.
A method of multicast data delivery in a radio resource control (RRC) inactive state, comprising the steps of:
- receiving, by a user equipment (UE) in an RRC connected state, an RRC release message indicating transitioning of the UE from the RRC connected state to an RRC inactive state the RRC release message further conveying multicast configuration parameters;
- and
- in response to joining a multicast group, determining a bandwidth part (BWP) for reception of paging information and multicast data during the RRC inactive state based on the multicast configuration parameters conveyed in the RRC release message, the multicast configuration parameters including paging occasion information and semi-persistent scheduling information for multicast reception in the RRC inactive state;
- and
- receiving the paging information and the multicast data via the determined BWP.
