Abstract:
A method may be provided to operate a wireless terminal in communication with a network node. The method may include receiving a Physical Downlink Control Channel, PDCCH, order from the network node. The PDCCH order may include an identification for a Random Access CHannel RACH occasion to be used for a RACH message 1 preamble transmission. Moreover, the identification may include a first index that indicates a set of RACH occasions and a second index that indicates the RACH occasion associated with the set. The method may also include transmitting a Message 1 preamble to the network node using the RACH occasion responsive to the PDCCH order.
