This work deals with the problem of radio resource\udallocation in a point-to-point multiple-input multiple-output\ud(MIMO) communications system with feedback of channel state\udinformation. A total pool of radio resources (power and transmission\udtime) is allocated among training, feedback, and data\udtransmission phases in order to maximize system performance\udin terms of throughput. The energy consumption associated to\udthe base band signal processing and decoding is also evaluated.\udThis resource allocation problem is studied analytically in a twoway\udtime division duplex (TDD) communications scenario with\udtime correlated channels, where the effect of feedback errors and\udfeedback delay is also taken into account.
