Title:
RANDOM ACCESS PROCEDURE IN NEXT GENERATION NETWORK
Document Type and Number:
Japanese Patent JP2023017872
Kind Code:
A
Abstract:
To provide an enhanced random access procedure that supports beam formation for new radio (NR) networks.SOLUTION: An NR node transmits downlink transmission beams during downlink sweep sub-frames. User equipment selects an optimal downlink transmission beam transmitted by a cell during the downlink sweep sub-frame, and determines an optimal downlink reception beam from the optimal downlink transmission beams. The user equipment determines a random access preamble and a physical random access channel (PRACH) resource through resource selection from the optimal downlink transmission beam, and transmits the random access preamble to the NR node with the determined PRACH resource.SELECTED DRAWING: Figure 37
