The channel model between the base station (BS) and the user 𝑘 can be expressed as the formula, where 𝐡_(𝑏𝑠,𝑘)¡ôℂ^(𝑁_𝐵¡¿1), 𝐡_(𝑏𝑠,𝑙)¡ôℂ^(𝑁_𝐵¡¿1), and ℎ_(𝑙,𝑘) respectively denote the channel vector from the BS to the user 𝑘, from the BS to the RIS, and from the RIS to the user 𝑘. Considering the conditions of hardware loss, the phase-independent amplitude model of RIS can be obtained as the formula.
