METHOD FOR RECEIVING OR TRANSMITTING BROADCAST SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
First Claim
1. A method for receiving broadcast signal through a new carrier type (NCT) in a wireless communication system, the method being performed by a user equipment and comprising:
- blind-decoding a physical broadcast channel (PBCH) received from a base station; and
acquiring the number of antenna ports and system information of the base station from the PBCH,wherein the blind decoding is performed within a candidate range for the blind decoding of the PBCH corresponding to a partial area of a downlink subframe, andwherein the candidate range is an area from which a symbol section of the downlink subframe to which a physical downlink control channel (PDDCH) of a neighboring base station is mapped is excluded, and is indicated by the base station in advance.

Abstract
A method for receiving a broadcast signal through a new carrier type (NCT) in a wireless communication system according to one embodiment of the present invention is executed by a terminal and comprises the steps of: blind-decoding a physical broadcast channel (PBCH) received from a base station; and acquiring a number of antenna ports and system information of the base station from the PBCH, wherein the blind decoding is executed within a candidate range for the blind decoding of the PBCH corresponding to a partial area of a downlink subframe, and the candidate range is an area in which a symbol section is excluded in a downlink subframe to which a physical downlink control channel (PDDCH) of a neighboring base station is mapped, and can be indicated by the base station in advance.

7. A method for transmitting broadcast signal through a new carrier type (NCT) in a wireless communication system, the method being performed by a base station and comprising:
-
receiving information on a position of a symbol of a downlink subframe, to which a physical downlink control channel (PDCCH) of a neighboring base station is mapped, from the neighboring base station to mitigate interference on a user equipment; and transmitting a physical broadcast channel (PBCH) to the user equipment within a candidate range for blind decoding of the PBCH corresponding to a partial area of the downlink subframe, wherein the candidate range is an area from which a symbol section of the downlink subframe to which the PDDCH of the neighboring base station is mapped is excluded, and is indicated to the user equipment in advance. - View Dependent Claims (8, 9, 10, 11, 12)
