A user terminal includes: a reception section that receives a downlink signal including a demodulation reference signal; a signal separation section that separates the demodulation reference signal from the downlink signal based on an expansion pattern obtained by applying a set expansion method to expand a basic pattern; and a channel estimation section that uses the demodulation reference signal to compute a channel estimation value. The basic pattern indicates resource elements to which a demodulation reference signal of 8 layers is mapped, and the expansion pattern indicates resource elements to which a demodulation reference signal of 16 layers is mapped.
