Please, how can the channel matrix be calculated in case of intercell interference. and the numerical values of the variables in the formula:

i + ∑(j=1, j≠i)^K

where 𝑯_𝒊𝒊 and 𝑯_𝒊𝒋 are the channel matrix between 𝑩𝑺𝒊 and 𝑪𝑼𝑬𝒊, CUEj (i, j ∈ {1, 2, . . . , K} , 𝑖≠𝑗.

𝑽𝒊 of dimension 𝑀 × 𝑑𝑖 and 𝑉𝑗 of dimension 𝑀 × 𝑑𝑗 are 𝑩𝑺𝒊 and 𝑩𝑺𝒋 respectively,

si with dimension di × 1 is the downlink data vector signal BSi

𝑛_𝑖 is additive white Gaussian noise.
