Abstract
A method for receiving a radio resource control (RRC) message by a user equipment (UE) is described. The method includes receiving an RRC connection reconfiguration message including mobility control information. In response to receiving the RRC connection reconfiguration message including mobility control information, a medium access control (MAC) entity of a secondary cell group (SCG) is released if any MAC entity of the SCG is established. In response to receiving the RRC connection reconfiguration message including mobility control information, a MAC entity of a master cell group (MCG) is reset.
Claims15
A method for receiving a radio resource control (RRC) message by a user equipment (UE), comprising:
- receiving an RRC connection reconfiguration message including mobility control information;
- starting synchronizing to a downlink of a target primary cell (PCell) in a case that the RRC connection reconfiguration message including the mobility control information is received;
- and
- resetting a medium access control (MAC) entity of a master cell group (MCG) and a MAC entity of a secondary cell group (SCG) if any MAC entity of the SCG is configured in the case that the RRC connection reconfiguration message including the mobility control information is received,
- wherein the MAC entity of the MCG and the MAC entity of the SCG are configured for the UE, the MCG includes at least one PCell, and the SCG includes at least one primary SCell (PSCell).
A user equipment (UE) for receiving a radio resource control (RRC) message, comprising:
- a processor;
- and
- memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
- receive an RRC connection reconfiguration message including mobility control information;
- start synchronizing to a downlink of a target primary cell (PCell) in a case that the RRC connection reconfiguration message including the mobility control information is received;
- and
- reset a medium access control (MAC) entity of a master cell group (MCG) and MAC entity of a secondary cell group (SCG) if any MAC entity of the SCG is configured in the case that the RRC connection reconfiguration message including the mobility control information is received,
- wherein the MAC entity of the MCG and the MAC entity of the SCG are configured for the UE, the MCG includes at least one PCell, and the SCG includes at least one primary SCell (PSCell).
A non-transitory, tangible computer-readable medium for receiving radio resource control (RRC) message by a user equipment (UE), comprising executable instructions for:
- receiving an RRC connection reconfiguration message including mobility control information;
- starting synchronizing to a downlink of a target primary cell (PCell) in a case that the RRC connection reconfiguration message including the mobility control information is received;
- and
- resetting a medium access control (MAC) entity of a master cell group (MCG) and MAC entity of a secondary cell group (SCG) if any MAC entity of the SCG is configured in the case that the RRC connection reconfiguration message including the mobility control information is received,
- wherein the MAC entity of the MCG and the MAC entity of the SCG are configured for the UE, the MCG includes at least one PCell, and the SCG includes at least one primary SCell (PSCell).
