Communication techniques

Aspects provide methods for controlling user equipment operation in a wireless communications network configured to support communication with the user equipment according to a communication mode which utilises repetition of messaging; computer program products and network nodes operable to perform those methods. One method comprises: determining a modulation and coding regime to be used by the user equipment; identifying a repetition regime to be implemented by the user equipment in conjunction with the modulation and coding regime; and communicating an indication of the determined modulation and coding regime and identified repetition regime to the user equipment. Aspects recognise that when implementing a coverage enhanced region within a network it is possible that fixed repetition levels can be defined for CE-MTC UE. Those fixed repetition levels can be implemented by a network and recognise differences between the CE-MTC UE radio condition. That is to say, the number of repetitions used may correspond to radio condition being experienced at a machine-type communication device: those in poorer coverage regions will be selected to receive a greater number of repetitions than those in a better radio coverage region. The granularity of such repetition levels may subject to a given operator's implementation of a coverage enhanced region. The first aspect recognises that it is possible to implement varying repetition levels for user equipment operating in the coverage enhanced region supported by a network access node. Those varying repetition levels can be configured at the network access node; for example, an eNodeB.
