20110003553 | APPARATUS AND METHOD FOR ALLOCATING DOWNLINK CONTROL CHANNEL - A method for allocating a downlink control channel in a fractional frequency reuse (FFR) system, includes: dividing a service frequency band of the system into a plurality of frequency partitions including a first frequency partition corresponding to a first frequency reuse factor, a second frequency partition corresponding Kth frequency reuse factor, and a third frequency partition; setting a transmission power level for each of the plurality of divided frequency partitions; allocating a downlink common control channel including non-user specific (NUS) control information common to every user to a particular frequency partition corresponding to the highest transmission power level among the set transmission power levels; and transmitting the NUS control information through the particular frequency partition. | 01-06-2011 |
20120120902 | APPARATUS AND METHOD FOR ALLOCATING ONE OR MORE RESOURCES TO REDUCE RESOURCE HOLE IN A WIRELESS ACCESS SYSTEM - Disclosed is a method for receiving allocated resources, by a terminal, in a wireless access communication system. In particularly, the present invention is to provide a method for receiving one or more resources in a wireless access communication system, the method comprising: receiving a control message from a network; checking the received control message whether the control message includes resource shift information; and receiving the one or more resources according to the resource shift information if it is checked that the control message includes the resource shift information, wherein the resource shift information comprises at least one of a resource shift indicator, a resource shift offset and a feedback allocation information. | 05-17-2012 |
20130279362 | Method and Apparatus for Selecting a Node in a Distributed Multi-Node System - This specification relates to a method for selecting a node in a serving cell in a distributed multi-node system, the method being characterized by comprising the steps of: receiving a channel state information reference signal of each node in the serving cell from a base station; measuring a signal intensity or interference level about the respective nodes through the received channel state information reference signal; and determining at least one valid node from among the respective nodes based on the measured result, wherein the signal intensity or the interference level is expressed in any one of channel state information reference signal received power (CSI-RSRP), channel state information reference signal received quality (CSI-RSRQ), and channel state information reference signal's signal intensity (CSI-RSSI). | 10-24-2013 |
