1. A mobile device for transmitting data to and receiving data from infrastructure equipment including
transmitter circuitry configured to transmit the data to the mobile device; and
controller circuitry configured to control the transmitter circuitry to transmit a first position reference signal in a first subframe and a second position reference signal in a second subframe, wherein the second position reference signal is a time adjusted version of the first position reference signal, the amount of time adjustment being determined by dividing the sample time at which the mobile device samples the position reference signal a number of time adjustments to be made plus one,
the mobile device comprising:
receiver circuitry configured to receive data from the infrastructure equipment; and
controller circuitry configured to:
control the receiver circuitry to receive the first position reference signal in the first subframe and the second position reference signal in the second subframe;
sample the channel impulse response of the first position reference signal and the channel impulse response of the second position reference signal at the sampling rate;
combine the sampled channel impulse response of the first position reference signal and the sampled channel impulse response of the second position reference signal to form a combined signal; and
determine a time of provision of the combined signal based on the combination of the sampled channel impulse response of the first position reference signal and the sampled channel impulse response of the second position reference signal.
