METHOD FOR TRANSCEIVING CONTROL INFORMATION, AND APPARATUS FOR SAME

摘要

The present invention relates to a wireless communication system. In detail, provided are a method by which a terminal receives a control channel signal in a wireless communication system, and an apparatus for same, including the steps of: receiving a subframe including a plurality of control channel sets, wherein each control channel set includes a plurality of control channel candidates; and monitoring at least one control channel set in the subframe for receiving the control channel signal, wherein the plurality of control channel candidates are scrambled by a scrambling sequence having a control channel set-specific initialization value in each control channel set.

1. A method of receiving a control channel signal by a user equipment in a wireless communication system, the method comprising:
receiving a subframe containing a plurality of control channel sets, wherein each of a plurality of the control channel sets contains a plurality of control channel candidates; and monitoring at least one control channel set in the subframe for receiving the control channel signal, wherein a plurality of the control channel candidates in each of a plurality of the control channel sets are scrambled by a scrambling sequence containing cinit of a following equation as an initialization value:
cinit=X·214+q·213+└ns/2┘·29+IDk  Equation where, X is to an integer containing 0, q is to an integer containing 0, ns is a slot number in a radio frame, IDk is identification information defined for a control channel set #k, and └ ┘ is a flooring function.
