Methods and Apparatuses for Determining a Placement and Duration of a Transient Period of an On/Off Time Mask for Uplink Transmission

A wireless device, comprising:

• a receive;
• a transmitter;
• and
• processing circuitry coupled to the receiver and the transmitter, the processing circuitry configured to:
• receive, via the receiver, an uplink grant from a network node, the uplink grant scheduling one or more uplink transmissions by the wireless device;
• select an ON/OFF time mask to use for transmitting the one or more uplink transmissions;
• and
• determine, based on the received uplink grant, an allowed placement of a transient period of the selected ON/OFF time mask and a duration of the transient period to use for the one or more uplink transmissions.

A network node, comprising:

• a receiver;
• a transmitter;
• and
• processing circuitry, the processing circuitry configured to:
• determine a position of a reference symbol in one or more uplink transmissions to be scheduled for a wireless device;
• and
• send, via the transmitter, an uplink grant to the wireless device for scheduling the one or more uplink transmissions, the uplink grant indicating the determined position of the reference symbol in the one or more uplink transmissions.
