Calculating timing offset in wireless communications

A user equipment device, for use in a cellular communications network, the user equipment device comprising:

• communication circuitry configured for communicating with base stations in the cellular communications network;
• and
• processing circuitry operatively associated with the communication circuitry and configured to:
• detect a timing signal from a serving base station;
• obtain timing information from at least one other base station;
• set a value for a transmission time offset based on the detected timing signal from the serving base station and the timing information obtained from the at least one other base station;
• and
• transmit signals to the serving base station using the set value for the transmission time offset, wherein to transmit the signals to the serving base station, the processing circuitry is configured to transmit the signals to the serving base station with a power that is determined based on an uncertainty in the set value for the transmission time offset.

A method of operation of a base station in a cellular communications network, the method comprising:

• instructing a device to:
• detect a timing signal from the base station;
• obtain timing information from at least one other base station;
• set a value for a transmission time offset based on the detected timing signal from the base station and the timing information from the at least one other base station;
• and transmit signals to the base station using the set value for the transmission time offset, wherein instructing the device to transmit the signals to the base station comprises instructing the device to transmit the signals to the base station with a power that is determined based on an uncertainty in the set value for the transmission time offset.
