摘要：
A pilot transmission in a multiple antenna closed loop transmission time multiplexes a beam-specific pilot and an antenna-specific pilot in two short blocks of one uplink sub-frame. The beam-specific pilot is transmitted as an in-band pilot with the same beam as data to provide optimal data demodulation/estimation. The antenna-specific pilot is transmitted as an out-band pilot to provide optimal beam selection.
