Abstract:
A terminal device includes a processor and a memory connected to the processor, wherein the processor executes a process including: receiving a resource specifying signal that specifies a random access resource used to transmit a preamble for random access; selecting one preamble from a plurality of preamble candidates previously acquired; and transmitting the selected preamble by using a random access resource arranged in timing based on a reception timing of the resource specifying signal.
