1. A terminal device for use with a wireless telecommunications system, the terminal device comprising:
a receiver;
a transmitter; and
circuitry configured to:
conduct a first measurement, including a plurality of measurements taken at a first rate, of a first parameter of a cell specific reference signal (CRS) transmitted by first infrastructure equipment of the wireless telecommunications network and received by the receiver, the first parameter being a reference signal received power (RSRP) or a reference signal receive quality (RSRQ) of the CRS;
determine whether the first parameter meets a predetermined criteria;
in a case that the first parameter is determined to meet the predetermined criteria, conduct a second measurement, including a plurality of measurements taken at a second rate higher than the first rate, of a second parameter of a mobility reference signal (MRS) transmitted by second infrastructure equipment of the wireless telecommunications network and received by the receiver, the second parameter being a RSRP or a RSRQ of the MRS; and
in a case that the first parameter is determined to not meet the predetermined criteria, reconduct the first measurement at the first rate of the first parameter of the CRS, wherein
the first infrastructure equipment currently serves the terminal device and the second infrastructure equipment serves an area neighboring a service area of the first infrastructure equipment.
