Downlink Transmission Model Sample Clauses

Downlink Transmission Model. ‌ 1k Nk Let denote the aggregate beamformer from all RRHs towards the k-th IT as wk = [wH , · · · , wH ]H ∈ CMN×1, where wnk ∈ CM×1 is the beamforming vector from the n-th RRH to the k-th IT, k ∈ Li. Similarly, the aggregate channel between all RRHs 1k Nk and the k-th IT is denoted as hk = [hH , · · · , hH ]H ∈ CMN×1, where hnk ∈ CM×1 is the channel vector between the n-th RRH and the k-th IT, k ∈ Li. The received signal at the k-th IT, k ∈ Li is given by zk = hHwksk + ∑ hHw js j + nk, ∀k ∈ Li (3.3) k k

Downlink Transmission Model. ‌ 1i Ni The aggregate beamforming vector from all the RRHs towards the i-th IT, i ∈ Li, as wi = [wH,··· , wH ]H ∈ CMN×1 is denoted, where wni ∈ CM×1 is the beamformer 1e Ne from the n-th RRH towards the i-th IT. ve = [vH , · · · , vH ]H ∈ CMN×1 represents the aggregate beamforming vector from all the RRHs to the e-th active ET. Similarly, let hni ∈ CM×1 represent the channel vector between the n-th RRH and the i-th IT, the aggregate channel vector between all the RRHs and the i-th IT is denoted by hi = [hH,··· , hH ]H ∈ CMN×1. The received signals at the i-th IT, i ∈ Li, is then 1i given by Ni yi = hH wis[IT] + ∑ hH w js[IT] + ∑ hHves[ET] + ni, (4.1) j/=i ∈Xx
