20120294153METHOD AND APPARATUS FOR REPORTING CHANNEL STATUS INFORMATION IN A WIRELESS COMMUNICATION SYSTEM - A base station in a downlink of a wireless communication system requires downlink channel status information of terminals to transmit link-adaptive transmission to the terminals. This channel status information is generated as a terminal receives a reference signal to be transmitted via the downlink, and fed back to the base station through a control channel of the uplink. Therefore, an increase in the transmission cycle of the reference signal and the feedback cycle of the channel status information may increase a difference between the channel status having been fed back from a terminal to the base station and the channel status at the point when data is actually transmitted to the terminal, thereby causing inefficient link-adaptive transmission and deteriorating the system performance. The present invention thus provides a method and apparatus for designing an uplink periodic feedback structure for reducing the channel status difference in case a reference signal for the estimation of a downlink channel status is transmitted over a prolonged cycle, and distributing a feedback overhead of terminals in terms of the system.11-22-2012

20110267955Monitoring pattern separation between component carriers based on user equipment RF layout - A network learns a user equipment's capability information whether the UE is capable of simultaneous and independent operation in multiple component carriers. The network configures a monitoring (e.g., discontinuous reception, RSRP/RSRQ measurements, PDCCH reception) pattern for each of multiple component carriers CCs that are configured for the UE in dependence on the received capability information. The capability information derives from the UE's RF layout; if the capability information says the UE is capable of such simultaneous and independent operation the network can assign for the CCs different monitoring patterns that are independent of one another and the UE will have no gaps where it cannot take or send a measurement. This knowledge is particularly useful if the CCs are frequency non-contiguous with one another. If the capability information says the UE is not so capable, the network must assign monitoring patterns to that UE for all its configured CCs that are not independent of one another.11-03-2011
