Power Allocation Schemes for Multicell Massive MIMO Systems [PDF]
arXiv, 2015 This paper investigates the sum-rate gains brought by power allocation strategies in multicell massive multipleinput multiple-output systems, assuming time-division duplex transmission. For both uplink and downlink, we derive tractable expressions for the achievable rate with zero-forcing receivers and precoders respectively.
