1. A method of controlling an infrastructure equipment forming part of a wireless communications network, the method comprising:
forming one or more beams which can be used by the infrastructure equipment to transmit data to one or more communications devices via a wireless access interface provided by the wireless communications network, each of the beams having a different angular bias with respect to a location of the infrastructure equipment,
transmitting, using a first of the beams, data to one of the communications devices,
changing, dependent on one or more sets of predetermined conditions being met, a beam width of the first of the beams, wherein the beam width increases relative to each previous beam width as a number of Physical Random Access Channel (PRACH) transmission attempts increases, and
re-transmitting, using the first of the beams having the changed beam width, the data to the one of the communications devices.
