Terminal and communication method
A terminal includes a reception unit configured to receive information for allocating uplink transmission from a base station; a control unit configured to determine a CP extension value in a case where a parameter for calculating the CP extension value is not configured by the base station upon receiving the information; and a transmission unit configured to execute the uplink transmission by applying the determined CP extension value.
1. A terminal comprising:
a reception unit configured to receive a parameter for calculating a cyclic prefix (CP) extension value; and
a control unit configured to determine the parameter for calculating the CP extension value, based on a timing advance value in a case where information of the parameter for calculating the CP extension value is not configured.
2. The terminal as claimed in claim 1 , wherein the control unit determines a value of the parameter such that the value is a maximum integer value that satisfies a condition formula including the timing advance value.
3. The terminal as claimed in claim 1 , wherein the parameter for calculating the CP extension value is C2 and C3.
4. The terminal as claimed in claim 2 , wherein the parameter for calculating the CP extension value is C2 and C3.
5. A system comprising:
a base station that includes
a transmission unit configured to transmit information of a parameter for calculating a cyclic prefix (CP) extension value, to a terminal; and
the terminal that includes:
a reception unit configured to receive the information of the parameter for calculating the CP extension value; and
a control unit configured to determine a value of the parameter for calculating the CP extension value, based on a timing advance value in a case where the information of the parameter for calculating the CP extension value is not configured.
