摘要： Techniques for rank adaptation and multiple-stream reverse link communications in a wireless access network are disclosed. A remote unit transmits one or more reverse link data streams using separate identifiers to a base station. The number of reverse link data streams may be determined according to feedback from the base station or it may be determined by testing one or more multiple-antenna transmit hypotheses. The base station may estimate channel conditions using information obtained from the one or more reverse link data streams and may determine a spatial rank of the communication channel. The remote unit may perform separate error control and power control processes for each reverse link data stream in cooperation with the base station.

摘要： A method for use by a remote unit in an Evolution Data Optimized (EVDO) network includes sending transmissions to a base station, each of the transmissions corresponding to a respective one of multiple hypotheses of multiple antenna usage. The method also includes receiving feedback from the base station in response to the transmissions, the feedback being uninformed of multiple antenna usage and using the feedback to select at least one of the hypotheses. The method further includes transmitting data using a multiple-antenna scheme associated with the selected hypotheses.

摘要： Systems and methodologies are described that facilitate constructing unitary matrices that may be utilized in linear precoding for multiple-input multiple-output (MIMO) wireless communication systems. Each unitary matrix may be generated by combining (e.g., multiplying) a diagonal matrix with a Discrete Fourier Transform (DFT) matrix. The unitary matrices may be utilized to provide feedback related to a channel and/or control transmission over a channel based upon obtained feedback.

摘要： Techniques to enhance the performance in a wireless communication system using segments called subbands and using precoding are shown. According to one aspect, the bandwidth for transmission to an access terminal is constrained to a preferred bandwidth which is less than the bandwidth available for transmission to an access terminal and precoding information related to the subcarriers within the constrained bandwidth is provided to a transmitter. The precoding information related to the subcarriers within a constrained bandwidth provides feedback about the forward link channel properties relative to different subbands and may be fed back on a channel associated with the bandwidth.
