Abstract
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.
Claims12
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.
A terminal in a wireless communication, the terminal comprising:
- a transceiver;
- and
- at least one processor configured to:
- control the transceiver to communicate 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;
- control the transceiver to receive, 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;
- release the first radio bearer based on the indication to perform full configuration;
- establish the second radio bearer for communicating with the second base station, based on the second configuration information;
- and
- control the transceiver to communicate with the second base station based on the second PDCP SN size for the second radio bearer.
