Abstract: Techniques for supporting distributed multiple-input multiple-output (MIMO) transmissions are described. In one design, a user equipment (UE) determines channel estimates for multiple cells and reports the channel estimates. The UE thereafter receives a data transmission sent by the multiple cells to the UE based on the channel estimates. The data transmission may include at least one data stream, and each data stream may be sent by one cell or the multiple cells to the UE. In another design, a UE determines first and second channel estimates for first and second cells, respectively, and reports the channel estimates. The UE then receives a first data transmission sent by the first cell to the UE based on the first channel estimate. The UE also receives a second data transmission sent by the second cell to another UE and steered away from the UE based on the second channel estimate.

Abstract: In accordance with a method for reducing interference in a wireless communication system, information about at least one disallowed beam corresponding to at least one served user may be determined. Scheduling decisions for served users may be made so as to avoid transmissions via the at least one disallowed beam. Data may be transmitted to users in accordance with the scheduling decisions.

Abstract: A method of wireless communication is disclosed that includes receiving detected channel information from a plurality of access terminals; selecting a set of access terminals from the plurality of access terminals based on the received channel information; creating a beamforming vector for each access terminal in the set of selected access terminals; and transmitting a signal using at least one of the created beamforming vectors. An apparatus for performing the method is also disclosed herein.

Abstract: Systems and methods for providing coverage to a first cell through a first antenna system and coverage to a second cell through a second antenna system. Data is also processed for transmission to a mobile device in the first cell using the first and second antenna systems.

Abstract: In accordance with a method for distributed beamforming based on carrier to caused interference, a base station may receive channel state information from users. The base station may select a codeword from a codebook. The codeword may be selected so as to maximize a utility function that is based on a signal-to-caused-interference-plus-noise ratio. The base station may use the codeword for beamforming.
