Abstract: The present disclosure relates to random access in mobility in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device comprises: receiving, from a network, skip information for a random access channel (RACH) and information for a revert timer; performing a RACH-less handover to a target cell based on the skip information and starting the revert timer; determining that the RACH-less handover stops while the revert timer is running; and upon an expiry of the revert timer, transmitting a random access preamble with a ramped transmission power, wherein the ramped transmission power is higher than an initial transmission power of the random access preamble.

Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: receiving system information including a threshold for the EDT; determining whether or not a condition for initiating the EDT is satisfied, by comparing the threshold for the EDT with a size of data for transmission; if the condition is satisfied, performing the EDT; and if the condition is not satisfied, performing a radio resource control (RRC) connection establishment or resume procedure.

Abstract: A method and apparatus for provision of random access channel (RACH) related information for connection failure detection in a new radio access technology (NR) is provided. For example, a first gNB receives, from a wireless device, random access channel (RACH) related information and cell information for a radio link failure (RLF), and transmits, to a second gNB, the RACH related information and the cell information for the RLF. For another example, a gNB central unit (gNB-CU) of a first gNB receives, from a second gNB, RACH related information and cell information for RLF, and transmits, to a gNB distributed unit (gNB-DU) of the first gNB, information for an RACH configuration based on the RACH related information and the cell information for the RLF.

Abstract: The present disclosure relates to handling a connection re-establishment in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving a conditional mobility command; initiating a conditional mobility based on the conditional mobility command; performing a radio link monitoring (RLM) on a source cell during the conditional mobility; and performing a radio resource control (RRC) re-establishment based on that the conditional mobility fails and a radio link failure (RLF) occurs as a result of the RLM.
