To improve spectral efficiency of Device-to-Device multicast (D2DM) communication. we study the joint optimization of subcarrier and power allocation in D2DM communications underlaying cellular system with extremel large-scale multi-input-multi-output (XL-MIMO) in this paper. Specifically. we aim to maximize the aggregate multicast data rate of all D2D groups (DGs) while guaranteeing ... https://ashleyshomestores.shop/product-category/square-counter-tbl-set-5-cn/
