USER MOBILITY METHOD AND DEVICE
A base station (BS), a User Equipment (UE), and a method performed by a BS and/or a UE are provided. The method includes transmitting, by the BS, a Radio Resource Control (RRC) message to a User Equipment (UE), the RRC message indicating whether at least one of a Radio Link Control (RLC) entity and a Packet Data Convergence Protocol (PDCP) entity is to be reestablished, wherein the RRC message configures the UE to reestablish the RLC entity in a case that the RRC message indicates that the RLC entity is to be reestablished, and the RRC message configures the UE to reestablish the PDCP entity in a case that the RRC message indicates that the PDCP entity is to be reestablished.
1 . A method performed by a base station, the method comprising:
transmitting a Radio Resource Control (RRC) message to a User Equipment (UE), the RRC message indicating whether at least one of a Radio Link Control (RLC) entity and a Packet Data Convergence Protocol (PDCP) entity is to be reestablished, wherein
the RRC message configures the UE to reestablish the RLC entity in a case that the RRC message indicates that the RLC entity is to be reestablished, and
the RRC message configures the UE to reestablish the PDCP entity in a case that the RRC message indicates that the PDCP entity is to be reestablished.
2 . A base station, comprising:
transmitting circuitry configured to transmit a Radio Resource Control (RRC) message to a User Equipment (UE), the RRC message indicating whether at least one of a Radio Link Control (RLC) entity and a Packet Data Convergence Protocol (PDCP) entity is to be reestablished, wherein
the RRC message configures the UE to reestablish the RLC entity in a case that the RRC message indicates that the RLC entity is to be reestablished, and
the RRC message configures the UE to reestablish the PDCP entity in a case that the RRC message indicates that the PDCP entity is to be reestablished.
3 . A User Equipment (UE), comprising:
receiving circuitry configured to receive, from a base station, a Radio Resource Control (RRC) message; and
processing circuitry, coupled to the receiving circuitry, configured to:
determine whether the RRC message includes a first indication indicating that a Radio Link Control (RLC) entity is to be reestablished;
reestablish the RLC entity in response to determining that the RRC message includes the first indication;
determine whether the RRC message includes a second indication indicating that a Packet Data Convergence Protocol (PDCP) entity is to be reestablished; and
reestablish the PDCP entity in response to determining that the RRC message includes the second indication.
