TERMINAL DEVICE, WIRELESS TRANSMISSION METHOD, BASE STATION DEVICE, AND CHANNEL ESTIMATION METHOD

摘要

In the present invention, when CoMP is applied, it becomes possible to allocate a UE-dedicated reference signal sequence and transmit/receive wireless signals without causing an increase in inter-cell interference. The present invention adopts a configuration such that when cooperative reception by a plurality of base stations is not applied, a reference signal sequence determined from a selection baseline value corresponding to the number of a sequence group allocated to a cell belonging to the device in question is selected from among a plurality of selection baseline values as a reference signal sequence for non-cooperative reception, whereas when cooperative reception by a plurality of base stations is applied, a reference signal sequence determined from one or more intermediate selection baseline values set between two adjacent selection baseline values corresponding to the number of a sequence group allocated individually to a terminal device is selected among the plurality of selection baseline values as a reference signal sequence for cooperative reception differing from the reference signal sequence for non-cooperative reception, and a reference signal is generated on the basis of the selected reference signal sequence.
