METHOD AND APPARATUS FOR PREVENTING INTER-CELL INTERFERENCE IN A HETEROGENEOUS NETWORK SYSTEM
First Claim
1. A method of configuring a subframe arrangement, which is configured by an interfered cell in a wireless communication system, comprising the steps of:
- receiving a subframe arrangement information including a first bitmap for defining a subframe pattern for the interfered cell and a second bitmap for defining an HARQ (hybrid automatic repeat and request) process pattern of the interfered cell from an interfering cell;
configuring the subframe arrangement of the interfered cell based on the first bitmap and the second bitmap; and
performing a scheduling for a user equipment belonging to the interfered cell using the configured subframe arrangement,wherein a downlink signal of the interfering cell is not transmitted in one or more subframes designated by the subframe pattern for the interfered cell and wherein a size of the second bitmap is 8 bits.

Abstract
The present application relates to a method for a victim cell to construct a subframe alignment in a wireless communication system. More particularly, the method comprises the following steps: receiving, from an interfering cell, subframe alignment information including a first bitmap for defining a subframe pattern for the victim cell and a second bitmap for defining a hybrid automatic repeat and request (HARQ) process pattern of the victim cell; constructing a subframe alignment of the victim cell on the basis of the first bitmap and second bitmap; and performing scheduling for a terminal in the victim cell using the constructed subframe alignment. A downlink signal of the interfering cell may not be transmitted in one or more subframes designated by the subframe pattern for the victim cell, and the second bitmap has a size of 8 bits.

10. A base station device in a wireless communication system, comprising:
-
a receiving module configured to receive a subframe arrange information including a first bitmap for defining a subframe pattern for the base station device and a second bitmap for defining an HARQ (hybrid automatic repeat and request) process pattern of the base station device from an adjacent base station; a processor configured to configure the subframe arrangement of the interfered cell based on the first bitmap and the second bitmap; and a transmitting module configured to transmit a downlink signal to a user equipment belonging to the base station device in one or more subframes designated by the subframe arrangement, wherein a downlink signal of the adjacent base station is not transmitted in one or more subframes designated by the subframe pattern for the base station device and wherein a size of the second bitmap is 8 bits. - View Dependent Claims (11, 12, 13, 14, 15)
