Abstract

A wireless telecommunications method, a computer program product and network nodes are disclosed. The wireless telecommunications network node method comprises on a failure to establish a connection after initiating a RACH procedure, repeatedly transmitting a RACH preamble signature using a defined set of resource blocks of an uplink channel. In this way, when a conventional RACH procedure fails to establish a connection with the network, a modified RACH procedure is instead initiated. This modified RACH procedure transmits a RACH preamble signature repeatedly using a repeating set of resource blocks which are repeatedly allocated from the uplink channel. This enables the RACH preamble signature to be repeatedly transmitted so that the energy from these repeated transmissions may be combined by the network in order to detect the presence of the RACH preamble signature transmitted by network nodes in a poor coverage area such as, for example, an MTC device located in a basement.
