Abstract
Systems, apparatuses, and methods for a handover procedure in heterogeneous networks are provided. In particular, an intermediate handover (IHO) is introduced. Certain aspects of the disclosure involve, a method, performed at a first base station of a wireless communications network. An indication that a user equipment (UE) is receiving coverage signal from a second base station can be received. A data packet destined for the UE can be transmitted to the second base station. A communications link with the UE can be maintained after transmitting the data packet to the second base station.
Claims29
A method performed at a first base station of a wireless communications network, the method comprising:
- receiving an indication that a user equipment (UE) is receiving coverage signal from a second base station;
- forwarding information destined for the UE to the second base station;
- and
- maintaining a communications link with the UE after forwarding the information to the second base station.
A method performed at a first base station of a wireless communications network, the method comprising:
- receiving a request for an intermediate handover (IHO) from a second base station;
- accepting the request to perform the IHO;
- receiving a data packet destined for a UE from the second base station;
- transmitting the received data packet to the UE;
- and
- maintaining a communications link with the UE after receiving the data packet from the second base station.
A base station in a wireless communications network, the base station configured to:
- receive an indication that a user equipment (UE) is receiving coverage signal from a second base station;
- forward information destined for the UE to the second base station;
- and
- maintain a communications link with the UE after forwarding the information to the second base station.
