Abstract

See full text

A communications system including an infrastructure equipment, forming part of a mobile communications network, that transmits and receives data to/from a user device via a wireless access interface using a plurality of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers that extend across a first bandwidth. The infrastructure equipment is configured to transmit repeatedly signals representing a same instance of user device payload data in a second bandwidth less than and within a first bandwidth, and includes a subset of the OFDM subcarriers. The user device is configured to receive one or more of the signals repeatedly transmitted across the second bandwidth, to store in a memory signals representing the repeatedly transmitted signals received across the second bandwidth and to combine the stored signals, and to detect the user device payload data from the combined signals, the user device having been provided with an indication of the second bandwidth.
