摘要： A network element in a first cell in a wireless telecommunication network is provided. The network element comprises a processor configured such that the network element provides uplink and downlink grants in the first cell, wherein the first cell is a low-power cell within the coverage area of a second, high-power cell, and wherein the first cell acts as a secondary cell and the second cell acts as a primary cell in a carrier aggregation mode, and wherein at least one uplink control signal is received by one of only the first cell or both the first cell and the second cell.

摘要： A user equipment (UE) receives, from a wireless access network node of a source cell, a Radio Resource Control (RRC) message identifying a subframe containing information relating to an uplink grant to be sent by a target cell. The UE detects the uplink grant in the identified subframe transmitted by a target wireless access network node of the target cell. The UE sends, in response to the UE successfully accessing the target cell or detecting the information relating to the uplink grant, an RRC message to the target cell to handover from the source cell to the target cell.

摘要： 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.
