Method of transmitting and receiving scheduling information in a wireless communication system
First Claim
1. A method of performing a procedure for transmitting PDCCH signal from a network of a wireless communication system, the method comprising transmitting a subframe including a control information transmission region, wherein the control information transmission region comprises starting OFDM symbols and includes a plurality of sub-control regions;
- identifying a partial set of the plurality of sub-control regions, which are allocated to user equipment (UE); and
transmitting the PDCCH signal for the UE via the partial set of entire the plurality of sub-control regions;
wherein the PDCCH signal includes scheduling information for the UE, and wherein each sub-control region constituting the control information transmission region is an independent control channel.

7. A method of performing a procedure for receiving PDCCH signal at a user equipment in a wireless communication system, the method comprising:
-
receiving a subframe including a control information transmission region, wherein the control information transmission region comprises starting OFDM symbols and includes a plurality of sub-control regions; monitoring only a partial set of the plurality of sub-control regions for receiving the PDCCH signal; identifying, in the monitored partial set of the plurality of sub-control regions at least one sub-control region allocated to the user equipment; receiving scheduling information for the user equipment, through the allocated at least one sub-control region; and if scheduling information allocated to the user equipment is detected in the allocated at least one sub-control region, performing an operation in accordance with the scheduling information, wherein each sub-control region constituting the control information transmission region is an independent control channel. - View Dependent Claims (8, 9, 10, 11)
