Abstract
A method in a wireless terminal of a telecommunications system comprises the steps of using an enhanced physical downlink control channel to receive a downlink assignment of one or more downlink messages relating to a random access procedure, prior to an enhanced physical downlink control channel being formally configured for use with the wireless terminal. A corresponding method in a network node of a telecommunications system comprises the steps of transmitting a downlink assignment of one or more downlink messages relating to a random access procedure to a wireless terminal using an enhanced physical downlink control channel, ePDCCH, prior to the enhanced physical downlink control channel being formally configured for use with the wireless terminal. This has the advantage of relieving a PDCCH bottleneck of the telecommunications system.
