Abstract
Official abstract text for this publication.
The present specification relates to a communication method and a communication device, and a random access method of a user equipment (UE), according to one embodiment of the present specification, comprises the steps of: sensing a random access trigger in a connected state; determining the type of the random access trigger when the random access trigger is sensed; and performing congestion control if the type of the random access trigger is a preset type.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method by a terminal in a wireless communication, the method comprising: communicating with a first base station based on a first packet data convergence protocol sequence number (PDCP SN) size for a first radio bearer, the first radio bearer being configured based on first configuration information; receiving, from the first base station, a control message for a handover from the first base station to a second base station, wherein the control message includes an indication to perform full configuration and second configuration information, the second configuration information including information on a second PDCP SN size for a second radio bearer; releasing the first radio bearer based on the indication to perform full configuration; establishing the second radio bearer for communicating with the second base station, based on the second configuration information; and communicating with the second base station based on the second PDCP SN size for the second radio bearer.
