Publication number: 20200274592Abstract: This disclosure provides methods, devices and systems for obtaining and providing channel feedback. In some implementations, a beamformee provides channel feedback to a beamformer that enables the beamformer to construct and independently precode two or more different sets of spatial streams for transmission to the beamformee. The independent precoding of the different sets of spatial streams ensures that the decodings of the different sets of spatial streams may be decoupled from one another at the beamformee. To provide the channel feedback, the beamformee partitions a channel estimate into two or more sub-estimates prior to performing a channel decomposition. In some implementations, the beamformee determines null-space-based projections of the sub-estimates before performing the channel decomposition.Type: ApplicationFiled: February 5, 2020Publication date: August 27, 2020Inventors: Yashwanth MANDULA, Gopala Krishna Murthy VEMULA, Suresh CHANDRASEKARAN, Ashutosh Deepak GORE, Swaroop VENKATESH, Louay JALLOUL, Ahmad Abdulrahman MOHAMMED, Yen-Feng LEE, Pedram PAYSARVI HOSEINI, Chi-Lin SU, Youhan KIM
