METHOD FOR USER EQUIPMENT MANAGING CONNECTION WITH SMALL CELL IN HETEROGENEOUS CELL ENVIRONMENT

摘要

Disclosed are a macro cell base station and a method for managing a connection with a small cell by: receiving a first measurement report message of the small cell from user equipment and deciding an activation of the connection with the small cell based on same; transmitting to the small cell a message indicating the activation of a connection with the user equipment, when the small cell has a different cell ID from a cell ID of the macro cell; receiving from the small cell a message for indicating scheduling for the user equipment; and indicating to the user equipment the connection with the small cell.

1. A method for managing connection between a macro cell and a small cell of a user equipment (UE) with dual connectivity in a heterogeneous cell deployment in which the macro cell and the small cell coexist, the method comprising:
receiving a first measurement report message about the small cell connected to the UE, from the UE; determining to activate connection with the small cell based on the first measurement report message; when the small cell has a different cell ID from a cell ID of the macro cell, transmitting a SCell activation indicator message for a command for activating connection with the UE, to the small cell; receiving a SCell activation response message for a command for scheduling the UE, from the small cell; and commanding the UE to activate connection with the small cell.
