Method and apparatus for receiving system information in wireless communication system
First Claim
1. A method for receiving system information at a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a subframe; and
performing blind decoding for a physical broadcast channel (PBCH) in a predetermined resource region of the subframe, based on a plurality of sequences masked on cyclic redundancy check (CRC) parity bits,wherein, when a cell-specific reference signal (CRS) is not present in the subframe,each of the plurality of sequences indicates one of a plurality of demodulation reference signal (DMRS) antenna port sets, oreach of the plurality of sequences indicates one of a plurality of diversity scheme sets, oreach of the plurality of sequences indicates one of a tracking reference signal (TRS) and a DMRS as a type of a reference signal,wherein, when each of the plurality of sequences indicates one of the plurality of diversity scheme sets, a sequence among the plurality of sequences indicates that precoding of the system information has been performed based on the following table;

Abstract
The method for receiving system information by a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of receiving a subframe; and a step of performing, for a physical broadcast channel (PBCH) in a predetermined resource region of the subframe, blind decoding based on a plurality of sequences to be masked to a CRC parity bit. If a cell-specific reference signal (CRS) does not exist in the subframe, each of the plurality of sequences indicates pieces of individual information contained in one or more of a reference signal type set, a demodulation reference signal (DMRS) antenna port information set and diversity scheme information set.

9. A user equipment in a wireless communication, the user equipment comprising:
-
a radio frequency (RF) module; and a processor operably coupled with the RF module, wherein the processor is configured to perform blind decoding for a physical broadcast channel (PBCH) in a predetermined resource region of a received subframe, based on a plurality of sequences masked on cyclic redundancy check (CRC) parity bits, wherein, when a cell-specific reference signal (CRS) is not present in the subframe, each of the plurality of sequences indicates one of a plurality of demodulation reference signal (DMRS) antenna port sets, or each of the plurality of sequences indicates one of a plurality of diversity scheme sets, or each of the plurality of sequences indicates one of a tracking reference signal (TRS) and a DMRS as a type of a reference signal, wherein, when each of the plurality of sequences indicates one of the plurality of diversity scheme sets, a sequence among the plurality of sequences indicates that precoding of the system information has been performed based on the following table;
