Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, a user equipment (UE) may receive a downlink (DL) scheduling command to schedule a DL data transmission from a base station. The UE may identify a scheduled slot for transmission of hybrid automatic repeat request (HARQ) feedback corresponding to the DL data transmission based on a received slot of the DL data transmission and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified from a value set based on an indicator comprised in the DL scheduling command, or may be identified using the various other techniques described herein.

The number of uplink subframes may be indicated by the uplink scheduling parameter.
