TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

摘要

A first UL-DL configuration configured by using a common RRC message is set; it is determined whether or not the number of enhanced control channel elements in one enhanced physical downlink control channel set in a subframe is set to 0 in a case where an index of an uplink control channel resource is determined, based on whether or not the subframe is a predetermined special subframe in the first UL-DL configuration; a second UL-DL configuration indicated by downlink control information which is transmitted on a physical downlink control channel is set; and in a case where the second UL-DL configuration is set, determination is performed based on whether or not the subframe is the predetermined special subframe in the second UL-DL configuration.

主权项

1. A terminal device comprising:
a higher layer processing unit that sets a first UL-DL configuration configured by using a common RRC message; and a control unit that determines whether or not the number of enhanced control channel elements in one enhanced physical downlink control channel set in a subframe is set to 0, based on whether or not the subframe is a predetermined special subframe in the first UL-DL configuration, in a case where an index of an uplink control channel resource is determined, wherein in a case where a second UL-DL configuration indicated by downlink control information which is transmitted on a physical downlink control channel is set, the control unit sets the number of enhanced control channel elements in the one enhanced physical downlink control channel set in the subframe, to 0 in a case where the index of the uplink control channel resource is determined in a case where the subframe is the predetermined special subframe in the second UL-DL configuration, and the predetermined special subframe is a subframe including three regions which are a region (DwPTS) in which downlink transmission is performed, a guard period (GP), and a region (UpPTS) in which uplink transmission is performed, in this order.
