Abstract
Embodiments of the present disclosure relate to method and apparatus for handing over a UE in an IAB network. According to some embodiments of the disclosure, a UE may: communicate with a first BS via a wireless network node; receive an RRC reconfiguration message for handing over the UE from the first BS to a second BS together with the wireless network node; and in response to receiving the RRC reconfiguration message, maintain an air interface between the UE and the wireless network node while performing the handover from the first BS to the second BS.
Claims20
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- communicate with a first base station (BS) via a wireless network node;
- receive a radio resource control (RRC) reconfiguration message for handing over the UE from the first BS to a second BS together with the wireless network node;
- and
- in response to receiving the RRC reconfiguration message, maintain an air interface between the UE and the wireless network node while performing the handover from the first BS to the second BS.
A first base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the first BS to:
- transmit, to a second BS, a handover (HO) request message for handing over a user equipment (UE) served by a wireless network node from the first BS to the second BS together with the wireless network node;
- and
- receive, from the second BS, a HO request acknowledgement message in response to the HO request message.
A method performed by a user equipment (UE), the method comprising:
- communicating with a first base station (BS) via a wireless network node;
- receiving a radio resource control (RRC) reconfiguration message for handing over the UE from the first BS to a second BS together with the wireless network node;
- and
- in response to receiving the RRC reconfiguration message, maintaining an air interface between the UE and the wireless network node while performing the handover from the first BS to the second BS.
A method performed by a first base station (BS), the method comprising:
- transmitting, to a second BS, a handover (HO) request message for handing over a user equipment (UE) served by a wireless network node from the first BS to the second BS together with the wireless network node;
- and
- receiving, from the second BS, a HO request acknowledgement message in response to the HO request message.
