Telecommunication control method, telecommunication system, and base station apparatus involving an intercell interference control technique

摘要

A telecommunication control method for a heterogeneous network is provided. Uplink interference created by first user equipment (MUE) connected to a first-type cell (MeNB) is detected at the second-type cell (HeNB). The second-type cell reports the interference pattern of the detected interference to the first-type cell. The first-type cell identifies the interfering first user equipment based upon the interference pattern. The first-type cell notifies the second-type cell of the scheduling information of the interfering first user equipment. The second-type cell determines scheduling for second user equipment (HeUE) connected to the second-type cell based upon the scheduling information of the first user equipment.

主权项

1. A telecommunication control method in a heterogeneous network, comprising:
at a second-type cell, detecting uplink interference created by first or first set of user equipments connected to a first-type cell; reporting an interference pattern of the detected interference from the second-type cell to the first-type cell; at the first-type cell, identifying the interfering first or first set of user equipments based upon the interference pattern; at the first-type cell, notifying the second-type cell of scheduling information of the first or first set of user equipments; and at the second-type cell, determining scheduling for second or second set of user equipments connected to the second-type cell based upon the scheduling information of the first or first set of user equipments.
