We study mutually unbiased bases in ℂd ⊗ ℂ2ld′ . A systematic way of constructing mutually unbiased maximally entangled bases (MUMEBs) in ℂd ⊗ ℂ2ld′ (l ∈ ℤ+) from MUMEBs in ℂd ⊗ ℂd′(d′ = kd,k ∈ ℤ+), and a general approach to construct mutually unbiased unextendible maximally entangled bases (MUUMEBs) in ℂd ⊗ ℂ2ld′ (l ∈ ℤ+) from MUUMEBs in ℂd ⊗ ℂd′(d′ = kd + r,0 < r < d) have been presented. Detailed examples are given.
