Repetitive transmission for NB-IoT
First Claim
1. A terminal device for use with a wireless telecommunications network, the terminal device comprising:
- a receiver; and
a controller operable to control the receiver to receive data from the wireless telecommunications network, wherein the data is transmitted using a candidate of a radio search space, the radio search space being defined by a plurality of candidates and each candidate of the radio search space being defined by a set of time and/or frequency radio resources for use in repetitions, the repetitions corresponding to in repeatedly transmitting the data a number of times associated with that candidate, and wherein the controller is operable to control the receiver to attempt to receive the data from each candidate of the radio search space;
whereinthe controller is operable to determine the radio search space based on a predetermined radio search space and one or more multiplier values, wherein the number of times that data is repeatedly transmittable using each candidate of the radio search space is determined using multiplication of a predetermined number of times that data is repeatedly transmittable using a corresponding candidate of the predetermined radio search space with a respective one of the multiplier values, wherein each of the one or more multiplier values is variable based on a value of each of one or more predetermined parameters, andin response to a coverage level resulting in the repetitions exceeding a predetermined threshold, the controller is operable to automatically apply power boosting on a physical resource block in which a paging search space is transmitted.
