The UE may receive an indication of a parameter d to use for determining a start of a reference UL resource (RUR). The parameter d may be UE-specific. The UE may further receive a physical downlink control channel (PDCCH) that includes a downlink control information (DCI) to indicate that a UL transmission is to be canceled in a RUR. The UE may determine a starting symbol of the RUR based on the parameter d. In embodiments, the UE may scale the parameter d based on a first subcarrier spacing (SCS) associated with the parameter d and a second SCS associated with the uplink transmission to obtain a scaled parameter d′ that is used to determine the starting symbol of the RUR. Other embodiments may be described and claimed. ## Claims ### Claim 1 One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to: receive an indication of a parameter d that is associated with a first subcarrier spacing (SCS);
