US 2018/0323939 A1 · METHOD AND APPARATUS FOR SCHEDULING UPLINK TRANSMISSIONS WITH REDUCED LATENCY

Abstract

A configuration can be received from a network. The configuration can enable a device to receive downlink transmissions with different TTI lengths. A first downlink assignment can be received. The first downlink assignment can indicate downlink resources for a first downlink transmission corresponding to a first TTI length. A second downlink assignment can be received. The second downlink assignment can indicate downlink resources for a second downlink transmission corresponding to a second TTI length. The first and the second downlink transmissions can be received. A number of acknowledgment bits needed can be determined in response to the first and second downlink transmissions at least based on the second downlink assignment. The acknowledgment bits can be transmitted in response to the first and second downlink transmissions in an uplink control channel associated with the second downlink assignment. The first and the second transmit time interval lengths can be different.
