Claim of US Patent No. 10,893,510

1. A method for transmitting a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/non-acknowledgement (NACK), the method performed by a user equipment (UE) and comprising:receiving a time division duplex (TDD) uplink (UL)-downlink (DL) configuration for a serving cell, which is a frequency division duplex (FDD) based cell;
receiving an HARQ subframe offset related to the TDD UL-DL configuration for the serving cell; and
transmitting the HARQ ACK/NACK on an uplink subframe of the serving cell,
wherein the uplink subframe of the serving cell is a FDD subframe,
wherein the uplink subframe of the serving cell is determined based on the HARQ subframe offset and the TDD UL-DL configuration for the serving cell, and
wherein an uplink signal is not transmitted to the serving cell on a subframe other than the uplink subframe of the serving cell determined based on the HARQ subframe offset and the TDD UL-DL configuration for the serving cell.
