Abstract
A method and apparatus for measurement by a terminal and a base station in a wireless communication system supporting carrier aggregation are provided. The method for measurement by the terminal includes receiving, from a base station, a measurement interval for a secondary cell in a deactivated state, acquiring a measurement period based on the measurement interval, and measuring a signal of the secondary cell in the deactivated state, based on the measurement period. The measurement period is acquired by multiplying the measurement interval by a predefined value greater than 1.
Claims9
A method for measurement by a terminal in a wireless communication system supporting carrier aggregation, the method comprising:
- determining a first measurement period based on a discontinuous reception (DRX) cycle in case that a secondary cell is in an activated state;
- determining a second measurement period based on information on a measurement interval in case that the secondary cell is in a deactivated state, the information being received from a base station;
- and
- measuring a signal of the secondary cell, based on the determined first or second measurement period,
- wherein the second measurement period is determined by multiplying the measurement interval by a predefined value greater than 1.
A terminal in a wireless communication system supporting carrier aggregation, the terminal comprising:
- a transceiver;
- and a controller coupled with the transceiver and configured to:
- determine a first measurement period based on a discontinuous reception (DRX) cycle in case that a secondary cell is in an activated state,
- determine a second measurement period based on information on a measurement interval in case that the secondary cell is in a deactivated state, the information being received from a base station, and
- measure a signal of the secondary cell, based on the determined first or second measurement period, wherein the second measurement period is determined by multiplying the measurement interval by a predefined value greater than 1.
A base station in a wireless communication system supporting carrier aggregation, the base station comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- configure discontinuous reception (DRX) related parameters, and
- receive, from a terminal, a measurement result for a secondary cell,
- wherein a first measurement period for the secondary cell is determined based on a DRX cycle in case that the secondary cell is in an activated state,
- wherein a second measurement period for the secondary cell is determined based on information on a measurement interval in case that the secondary cell is in a deactivated state, the information being provided by the base station, and
- wherein the second measurement period is determined by multiplying the measurement interval by a predefined value greater than 1.
