1. A transmitting device comprising:
a buffer configured to store transmission data;
a first layer processor configured to execute processing for a packet data convergence protocol (PDCP) layer on the transmission data;
a second layer processor configured to execute processing for a medium access control (MAC) layer on the transmission data; and
a transmitter configured to transmit the transmission data processed by the first layer processor and the second layer processor; and
a receiver configured to receive, via a radio resource control (RRC) signal, information indicating a second discard time that is shorter than a first discard time in the PDCP layer, wherein
the first layer processor is configured to discard the transmission data stored in the buffer when the second discard time expires,
the first discard time is selected from any of a plurality of first candidates,
the second discard time is selected from any of a plurality of second candidates, and
a first minimum value among the plurality of first candidates is larger than a first maximum value among the plurality of second candidates.
