We investigate the effect of feedback delay on the outage probability of multiple-input single-output (MISO) fading channels. [...] Key Method With perfect CSIR, under a short-term power constraint, we determine: (a) the outage probability for beamforming with imperfect CSIT (BF-IC) analytically, and (b) the optimal spatial power allocation (OSPA) scheme that minimizes outage numerically. Results show that, for delayed CSIT, BF-IC is close to optimal for low SNR and uniform spatial power allocation (USPA) is…Expand

TLDR
Analysis of energy-efficient transmission strategies for a closed-loop downlink multiple-input-single-output (MISO) system shows that the EE- oriented design leads to a longer training duration than the SE-oriented design in general, and the transmission strategies are extended from single-user single-service to multiuser mixed-service scenarios.
