Title:
TERMINAL AND COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP2018067774
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress an increased calculation amount and interference between users.SOLUTION: A terminal 200 includes: a radio receiver unit 101 which receives a plurality of spatially multiplexed data signals which are MU-MIMO (Multi User-Multiple Input Multiple Output) transmitted from a base station; an inter-user interference power estimation unit 209 which estimates inter-user interference power using the transmission weight of another terminal which is MU-MIMO transmitted; a signal separation unit 212 which generates a reception weight using the inter-user interference power to separate the plurality of data signals using the reception weight; and a demodulation unit 213 which demodulates each of the plurality of separated data signals to calculate a soft decision value, and generates a soft decision weight using the inter-user interference power and the reception weight, to weight the soft decision value using the soft decision weight.SELECTED DRAWING: Figure 3
