RANDOM ACCESS METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18681464 titled 'RANDOM ACCESS METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation: The patent application describes a method and apparatus for random access in a wireless communication system. It involves a terminal transmitting a random access preamble to a network, monitoring downlink control information, and receiving downlink data based on scheduling information.
- Uses subcarrier spacing exceeding a predetermined threshold value for transmitting random access preamble.
- Monitors downlink control information based on a specific radio network temporary identifier (RNTI).
- Receives downlink data channel based on scheduling information included in the DCI.
- Determines specific RNTI using a modulo operation with 2M−K as a divisor, where M is associated with an offset value for distinguishing the type of random access procedure, and K is an integer exceeding 12.

Original Abstract Submitted
Disclosed are a method and apparatus for performing random access in a wireless communication system. A method by which a terminal performs a random access procedure in a wireless communication system, according to an embodiment of the present disclosure, comprises the steps of: transmitting a random access preamble to a network from a slot based on a subcarrier spacing (SCS) exceeding a predetermined threshold value; monitoring downlink control information (DCI) based on a specific radio network temporary identifier (RNTI) corresponding to the random access preamble; and receiving a downlink data channel from the network, on the basis of scheduling information included in the DCI, wherein the specific RNTI is determined on the basis of a value derived via a modulo operation using 2M−K as a divisor, M is associated with an offset value for distinguishing the type of the random access procedure, and K may be an integer exceeding 12.
