|1. (WO2017033837) USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD|
|Applicants:||NTT DOCOMO, INC.
|Title:||USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD|
The present invention appropriately performs random access even when a reduced transmission time interval (TTI) is applied. The present invention has: a control unit that controls communications that use a plurality of cells that include at least two cells that have different TTIs; a transmission unit that transmits a random access preamble; and a reception unit that receives a response signal for the random access preamble. The control unit performs control such that a response signal for a random access preamble transmitted using a first cell is received using a second cell.
