Codebook Based Precoding and Power Allocation for MU-MIMO Systems for Sum Rate Maximization
Article
  • Sep 2019
In this paper, we study the problem of downlink (DL) sum rate maximization in codebook based multiuser (MU) multiple input multiple output (MIMO) systems. The user equipments (UEs) estimate the DL channels using pilot symbols sent by the access point (AP) and feedback the estimates to the AP over a control channel. We present a closed form expressi...

... A novel transmitting antenna configuration scheme enabling MU-MIMO concurrent transmission with reduced overhead is proposed in 802.11 ay systems [14]. Codebook-based precoding and power allocation scheme to maximize the sum rate of an MU-MIMO system is developed based on the closed-form sum rate expression [15]. The main lobe interference is mitigated by using a joint frequency and time domain resource allocation scheme [16]. ...
