Abstract: A method by a user equipment (UE) in a wireless communication system includes: receiving a first physical downlink shared channel (PDSCH) transmission and a second PDSCH transmission that carry a same transport block (TB) and are associated with a first transmission configuration indicator (TCI) state and a second TCI state, respectively; determining a transport block size (TBS) of the first PDSCH transmission; and determining low-density parity-check (LDPC) base graph corresponding to the transport block based on the determined TBS for each of the first PDSCH transmission and the second PDSCH transmission, wherein the determined TBS of the first PDSCH transmission is applied to the second PDSCH transmission.

Abstract: An apparatus for driving a steering shaft in a motor-driven power steering system may include a pinion gear having a joining protrusion and a power transmission bearing member provided with a joining groove to be removably inserted with the joining protrusion of the pinion gear, wherein the power transmission bearing member rotates integrally with the pinion gear by being joined each other when the pinion gear is disengaged from a flywheel ring gear of an engine and thereby transmits rotation force of the power transmission bearing member to the wormwheel connected with a steering shaft.
