摘要： The present invention relates to user equipment (UE) having at least two transmit antennas that are capable of transmitting RF signals to a base station, which selects either an open-loop mode or a closed-loop mode depending on how the RF signals from the UE are changing. In the closed-loop mode, the base station periodically evaluates the RF signals from the UE and selects which of the UE's transmit antennas are to be used. This information is then sent to the UE. If the base station determines that the RF signals from the UE are changing too rapidly for effective control, then the base station selects the open-loop mode, such that the UE selects which of the UE's transmit antennas are to be used.

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.

摘要： Spatial multiplexing and transmit diversity can improve the capacity of a wireless communication system. The system and method adapts communication schemes for communication systems with multiple antennas utilizing at least two transmission modes. The at least two transmission modes can, but are not necessarily, used for uplink communications. The two transmission modes may be chosen from the group consisting of a single antenna mode, a diversity mode a spatial multiplexed mode and a mixed diversity and spatial multiplexed mode. The at least two transmission modes may involve adaptation among multiple transmitters. At least one receiver may indicate a transmission mode to be used by a transmitter for a subsequent transmission. A transmitter may determine a transmission mode to be used for a subsequent transmission. The transmission mode can be based on channel sounding.
