Abstract
A method and apparatus schedule uplink transmissions with reduced latency. A first downlink transmission can be received at a device in a first downlink TTI of a first duration in a first downlink subframe. A second downlink transmission can be received in a second downlink TTI of a second duration in a second downlink subframe. The first downlink TTI and second downlink TTI may not overlap. A first HARQ-ACK feedback and a first HARQ-ACK PUCCH resource can be determined in response to receiving the first downlink transmission in the first downlink TTI. The first HARQ-ACK PUCCH resource can be mapped to REs in a first uplink TTI of a third duration in a first uplink subframe. A second HARQ-ACK feedback and a second HARQ-ACK PUCCH resource can be determined in response to receiving the second downlink transmission in the second downlink TTI. The second HARQ-ACK PUCCH resource can be mapped to REs in a second uplink TTI of a fourth duration in the first uplink subframe. The first UL TTI can include a temporal portion that overlaps the second UL TTI. The first HARQ-ACK PUCCH resource or the second HARQ-ACK PUCCH resource can be selected based on at least the determined second HARQ-ACK …
