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, the first MAC CE comprises an identifier related to the first configuration information, applying the first configuration information at a first point of time, receiving from the base station a second MAC CE, and applying the second configuration information at a second point of time. The first point of time is determined based on a number of a first slot and HARQ feedback transmission for first MAC CE. The second point of time is determined based on a number of a second slot and HARQ feedback transmission for second MAC CE.
Claims2
A method performed by a terminal, the method comprising:
- receiving, by the terminal from a base station, a first Radio Resource Control (RRC) message, wherein the first RRC message comprises first configuration information, and wherein the first configuration information is related to a first set of serving cells;
- receiving, by the terminal from the base station, a second RRC message, wherein the second RRC message comprises second configuration information, and wherein the second configuration information is related to a second set of serving cells;
- 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 the first configuration information;
- starting application of the first configuration information at a first point of time, wherein the first point of time is determined based on a number of a first slot and Hybrid Automatic Repeat Request (HARQ) feedback transmission for the first MAC CE, and wherein the first slot is an uplink slot related to the HARQ feedback transmission for the first MAC CE;
- receiving, by the terminal from the base station, a second MAC CE, wherein the second MAC CE comprises an identifier related to the second configuration information;
- and
- starting application of the second configuration information at a second point of time, wherein the second point of time is determined based on a number of a second slot and HARQ feedback transmission for the second MAC CE, and wherein the second slot is an uplink slot related to HARQ feedback transmission for the second MAC CE.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controller configured to control the transceiver to:
- receive, from a base station, a first Radio Resource Control (RRC) message, wherein the first RRC message comprises first configuration information, and wherein the first configuration information is related to a first set of serving cells;
- receive, from the base station, a second RRC message, wherein the second RRC message comprises second configuration information, and wherein the second configuration information is related to a second set of serving cells;receive, from the base station, a first Medium Access Control (MAC) Control Element (CE), wherein the first MAC CE comprises an identifier related to the first configuration information;
- start application of the first configuration information at a first point of time, wherein the first point of time is determined based on a number of a first slot and Hybrid Automatic Repeat Request (HARQ) feedback transmission for the first MAC CE, and wherein the first slot is an uplink slot related to the HARQ feedback transmission for the first MAC CE;
- receive, from the base station, a second MAC CE, wherein the second MAC CE comprises an identifier related to the second configuration information;
- and
- start application of the second configuration information at a second point of time, wherein the second point of time is determined based on a number of a second slot and HARQ feedback transmission for the second MAC CE, and wherein the second slot is an uplink slot related to HARQ feedback transmission for the second MAC CE.
