Method and apparatus for measuring channel state information |
摘要 |
A method and apparatus for transmitting in a multi-antenna communication system (100). Each of a plurality of antennas (116,122) are assigned with a different one of a plurality of groups of sub-bands. The plurality of groups of sub-bands each include a different sub-set of the plurality of sub-bands, where the plurality of sub-bands of a first group are non-contiguous. Transmitting from the plurality of antennas (116) and simultaneously using the plurality of groups of sub-bands, where transmitting from each antenna (116) occurs on the group of sub-bands assigned to the antenna (116). A base station for use in the multi-antenna communication system (100) including a first processor (332) for pre-conditioning transmission data, assigning a plurality of pilot symbols to the plurality of transmit antennas (116), and assigning a plurality of sub-channel sub-sets to the plurality of antennas (116). The plurality of antennas (116) transmit each of the assigned plurality of pilot symbols over their respectiven assigned sub-channel sub-sets. |
