Abstract
A radio access network node generates a physical random access channel configuration and transmits the configuration to a user equipment. The user equipment may use multiple and different uplink resources indicated in the configuration to transmit multiple preamble portions to the radio access network node based on signal strengths corresponding to available downlink beams. The preamble portions may be the same preamble, different preambles assigned in the configuration to a beam ranking index that are to be transmitted in different uplink resources associated with downlink beams ranked by the user equipment according to signal strength, or different parts of a long spread-preamble. The radio access network node may combine the preamble portions to obtain a single preamble or may request a strongest beam indication from the user equipment if a preamble portion was received in a signal corresponding to a less-than-strongest downlink beam available to the user equipment.
