Method for base station transmitting downlink control channel in wireless communication system and apparatus for same
First Claim
1. A method for receiving a downlink control channel from a base station (BS) at a user equipment (UE) in a wireless communication system, the method comprising;
- receiving the downlink control channel using an aggregation of one or more resource units from the BS,wherein each of the one or more resource units comprises one or more resource sub-units,wherein, when a downlink bandwidth is equal to or larger than a first threshold value or when a number of available resources for the downlink control channel is smaller than a second threshold value, a number of the resource sub-units constituting each of the one or more resource units is determined to be a value larger than 1.

Abstract
In the present invention, a method for a base station transmitting a downlink channel is disclosed. More particularly, the method comprises the steps of: dividing each of one or more resources blocks, which are allocated for the downlink control channel, into a predetermined number of subsets; deciding the number of subsets that comprise a resource allocation basic unit for the downlink control channel, based on a start symbol and/or an end symbol of the downlink control channel; mapping a transmission resource on the downlink control channel as the resource allocation basic unit comprising the predetermined number of subsets; and transmitting the downlink control channel by using the transmission resource that is mapped.
