Abstract: The transmission of stand-alone, aperiodic CSI reports from a UE in carrier aggregation in an LTE network is optimized. The coding rate is indirectly controlled by varying the number of RBs allocated for the CSI report transmission. Two sets of serving cells are established, and the payload of each set is approximated. For each allowable number of RBs and each payload size, a threshold SINR is determined and stored. An initial number of RBs is selected, based on the number of cells. The actual SINR is measured, and compared to the threshold SINR for the number of RBs and payload size. The number of RBs to be allocated is varied based on the comparison, by varying an index into an array of allowable numbers of RBs. Link adaptation is performed based on observed decoding errors, in an outer loop control algorithm that prevents wind up. An optimization for the particular case of one PCell and one SCell is also presented.

Abstract: The present invention provides a method and an apparatus of relaying data in a wireless communication system based on Time Division Duplex (TDD). A relay station receives downlink data from a base station in an uplink subframe and relays the downlink data to at least one mobile station. Accordingly, the efficiency of resource allocation for a relay station can be improved.

Abstract: Reporting tools used to manage an asynchronous transfer mode (ATM) network. Tools include a trunk inventory reporting tool, a trunk utilization reporting tool, an exceptions reporting tool and a flow control processor activation utility. Reports generated by these the tools include information about the operation and capacity of trunks, switches and user network interfaces.
