    摘要: The present invention provides different scheduling criteria depending on overall system performance in an effort to maintain fairness among mobile terminals and sustain a required QoS level. The invention is particularly effective for multi-carrier systems, wherein scheduling must also take into consideration the carrier used to transmit the scheduled data. In one embodiment, the present invention determines the spread of throughput rates for all mobile terminals being served by a given base station and bases the scheduling criteria thereon. Preferably, a standard deviation calculation is used to measure the throughput spread. The standard deviation of throughput associated with a collective group of mobile terminals is indicative of the differences between the lowest and highest throughputs with respect to the average throughput for the collective group of mobile terminals.

    摘要: Node-B transmits a power profile of each frequency of transmission data as a step function to a UE. Each UE measures the amount of interference of a received signal, evaluates SINR over the entire frequency band with the power of the received signal, and transmits the evaluation result to Node-B. Node-B evaluates the interference profile in Node-B from the information about the SINR transmitted from the UE and the power of the transmission signal, and determines the frequency profile of the power of the signal transmitted to the UE.

    摘要: A new method of performing interference estimation to allow the data packets to be efficiently delivered in an OFDM system. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. Based on the estimated interference, the CIR can be determined by the BTS based on channel response estimates made by the BTS, or by the MS based on channel response estimates made for the uplink assuming a symmetrical channel. Numerical results show that the CIR estimation error could be very small if a sub-channel is considered as the minimum transmission unit. In terms of the aggregate throughput, the interference estimation method can provide a significant gain.

    摘要: A scheduler in a base station determines or estimates a cumulative throughput based on the scheduling criteria used by the base station. Based on the cumulative throughput for each slot, the mobile terminals are divided into one of two groups. The first group is provided for mobile terminals having a lower throughput, while the remaining mobile terminals are placed in a second group associated with higher throughput. The mobile terminal in the first group having the lowest throughput has data scheduled for transmission on the next slot over the best available carrier. The remaining mobile terminals in the first group are iteratively scheduled for transmission on the best remaining carriers, until no mobile terminals remain. Once scheduling for the first group is complete, scheduling for the second group can take place. Preferably, scheduling for the second group is performed to maximize throughput on the remaining carrier or carriers.
