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.

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.
