In contrast to the 4G LTE, one of the key requirements of 5G and beyond networks is ultra-high reliability. Towards this end, we investigate the problem of scheduling with joint power allocation for multi-user multiple-input multiple-output (MU-MIMO)

A wireless powered communication network (WPCN) is considered, which has a hybrid access point (H-AP) and two users with energy harvesting capabilities. The H-AP transfers energy to the users during downlink (DL) transmission, and the users transmit
