Abstract
In the present application, disclosed a method for a terminal setting a search region for a downlink channel in a wireless communication system. More specifically, the method comprises the steps of receiving from a base station information related to a starting symbol of the search region by way of upper layer signaling; setting the search region by using the information related to the starting symbol; and receiving the downlink control channel by performing blind coding on the search region, wherein the starting symbol of the search region changes according to the characteristic of a subframe which receives the downlink control channel.
Claims11
A method of setting a search space, which is set by a user equipment (UE) to detect a downlink control channel in a wireless communication system, the method comprising:
- receiving information on a starting symbol of the search space for an enhanced downlink control channel in a data region of a subframe from an epode B;
- and
- monitoring the enhanced downlink control channel by performing blind decoding on the search space which is set using the information on the starting symbol,
- wherein, when a downlink bandwidth assigned to the UE is greater than a threshold value, the starting symbol of the search space is determined as a symbol having an index #n indicated by the information on the starting symbol, and
- wherein, when the downlink bandwidth is smaller than the threshold value, the starting symbol of the search space is determined as a symbol having an index #n+1.
A user equipment in a wireless communication system, the user equipment comprising:
- a receiver configured to receive information on a starting symbol of a search space for an enhanced downlink control channel in a data region of a subframe from an eNode B;
- and
- a processor configured to monitor the enhanced downlink control channel by performing blind decoding on the search space which is set using the information on the starting symbol,
- wherein, when a downlink bandwidth assigned to the user equipment is greater than a threshold value, the starting symbol of the search space is determined as a symbol having an index #n indicated by the information on the starting symbol, and
- wherein, when the downlink bandwidth is smaller than the threshold value, the starting symbol of the search space is determined as a symbol having an index #n+1.
