TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD
First Claim
1. A radio communication terminal comprising:
- a controller, which,in response to receiving signaling specific to the radio communication terminal, determines a base sequence group based on the received signaling; and
in response to not receiving signaling specific to the radio communication terminal, determines a base sequence group which is allocated to a cell that contains the radio communication terminal;
wherein the controller, in operation, generates a sounding reference signal (SRS) using the determined base sequence group; and
a transmitter, which is coupled to the controller and which, in operation, transmits the generated SRS.

Abstract
A terminal device is equipped with: a sequence determination unit that determines a sequence number with a different pattern than the assignment pattern for the sequence number assigned to the cell in which the host device resides; a reference signal generation unit that generates a reference signal for a sequence group corresponding to the sequence number that has been determined; and a wireless transmission unit that transmits the reference signal that has been generated to a base station. The sequence determination unit employs a configuration whereby, with the sequence number assigned to the cell in which the host device resides as a cell-specific sequence number, a dynamic offset which periodically changes over time and for which the same value is not consecutive is added to the cell-specific sequence number, thereby determining a sequence number which never overlaps with the cell-specific sequence number.

10. A radio communication terminal comprising:
-
a receiver, which, in operation, receives an instruction specifically signaled to the radio communication terminal by a Radio Resource Control (RRC) layer, the instruction including a parameter of a sequence number; a controller, which is coupled to the receiver and which, in operation, configures a sequence number based on the received instruction, ignoring a sequence number allocated to a cell that contains the radio communication terminal, and generates a Sounding Reference Signal (SRS) of a sequence group corresponding to the configured sequence number; and a transmitter, which is coupled to the controller and which, in operation, transmits the generated SRS. - View Dependent Claims (11, 12)
