1. A method of operating a wireless terminal in communication with a network node, the method comprising:
receiving a Physical Downlink Control Channel, PDCCH, order from the network node, wherein the PDCCH order includes an identification for a Random Access CHannel, RACH, occasion to be used for a RACH message 1 preamble transmission, wherein the identification includes a first index that indicates a set of RACH occasions and a second index that indicates the RACH occasion associated with the set; and
responsive to the PDCCH order, transmitting a Message 1 preamble to the network node using the RACH occasion indicated by the first and second indexes together.
