Abstract
A method and apparatus for layer 2 mobility is provided. Method for lower layer mobility includes receiving from a base station a first RRC message and a second RRC message, receiving from the base station a first MAC CE, performing DRX operation based on the first DRX configuration information and the first identifier, receiving from the base station a second MAC CE, and performing DRX operation based on the second DRX configuration information and the second identifier. The first MAC CE comprises an identifier related to a first configuration information. The first configuration information comprises the first identifier and the first DRX configuration information.
Claims2
A method performed by a terminal, the method comprising:
- receiving, by the terminal from a base station:
- a first identifier;
- first configuration information;
- a second identifier;
- and
- second configuration information;
- receiving, by the terminal from the base station, a first Medium Access Control (MAC) Control Element (CE), wherein the first MAC CE comprises an identifier related to configuration information, and wherein the identifier related to configuration information indicates the first identifier;
- triggering, by the terminal in response to the first MAC CE, a random access procedure:
- transmitting, by the terminal to the base station in response to the first MAC CE, an uplink message, wherein:
- the uplink message comprises the identifier related to configuration information;
- and
- the identifier related to configuration information indicates a specific identifier corresponding to applied configuration;
- performing a Discontinuous Reception (DRX) operation based on the first configuration information;
- receiving, by the terminal from the base station, a second MAC CE, wherein the second MAC CE comprises the identifier related to configuration information, and wherein the identifier related to configuration information indicates the second identifier;
- transmitting, by the terminal to the base station and in response to the second MAC CE, the second uplink message, wherein:
- the second uplink message comprises the identifier related to configuration information;
- and
- the identifier related to configuration in the second uplink message indicates a second specific identifier corresponding to applied configuration;
- and
- performing a DRX operation based on the second configuration information.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive a signals;
- and
- a controller configured to control the transceiver to:
- receive, from a base station:
- a first identifier;
- first configuration information;
- a second identifier;
- and
- second configuration information;
- receive, from the base station, a first Medium Access Control (MAC) Control Element (CE), wherein the first MAC CE comprises an identifier related to configuration information, and wherein the identifier related to configuration information indicates the first identifier;
- trigger in response to the first MAC CE a random access procedure;
- transmit to the base station in response to the first MAC CE an uplink message, wherein:
- the uplink message comprises the identifier related to configuration information;
- and
- the identifier related to configuration information indicates a specific identifier corresponding to applied configuration;
- perform a Discontinuous Reception (DRX) operation based on the first configuration information;
- receive, from the base station, a second MAC CE, wherein the second MAC CE comprises the identifier related to configuration information, and wherein the identifier related to configuration information indicates the second identifier;
- transmit to the base station in response to the second MAC CE a second uplink message, wherein:
- the second uplink message comprises the identifier related to configuration information;
- and
- the identifier related to configuration in the second uplink message indicates a second specific identifier corresponding to applied configuration;
- and
- perform a DRX operation based on the second configuration information.
