Abstract: Certain aspects of the present disclosure relate to methods and apparatus that may be used to perform joint spatial processing for space frequency block coding and/or non-space frequency block coding channels in a wireless communications system. In aspects, apparatus and methods are provided for wireless communications, comprising receiving a signal from a serving cell and zero or more interfering cells, and processing the received signal, wherein the processing includes joint processing of at least two Resource Elements (REs), selected to conform to a Space Frequency Block Coding (SFBC) scheme in which transmitted data is modulated across two REs, to detect an interfering cell signal and canceling of the detected interfering cell signal from the received signal.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for performing joint demodulation using a Max-Log MAP algorithm in wireless communications systems. An exemplary method generally comprises receiving a signal comprising one or more serving streams and one or more interfering streams; and processing the signal by performing joint demodulation using a max log map (MLM) algorithm for at least one of the one or more serving streams or at least one of the one or more interfering streams.
