Abstract

The present disclosure relates to a communication scheme for convergence of an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and security related service, or the like) on the basis of a 5G communication technology and an IoT related technology. The present invention provides a method and an apparatus for efficiently transmitting or receiving system information by using a preamble in a next generation mobile communication system.

Claims10

Dependent claims

A method performed by a terminal in a wireless communication system, the method comprising:

receiving, from a first base station of a first radio access technology (RAT), first configuration information on a measurement, the first configuration information including first information on a first threshold for identifying whether to perform the measurement and second information on a measurement object;
identifying a RAT of a frequency to be measured based on the second information;
in case that the identified RAT of the frequency is the first RAT, identifying whether a reference signal received power (RSRP) for a primary cell (PCell) of the first base station is lower than the first threshold based on the first information and performing the measurement on the frequency of the first RAT based on the RSRP being lower than the first threshold;
and
in case that the identified RAT of the frequency is a second RAT, performing the measurement on the frequency of the second RAT, based on the second RAT being indicated in the second information.

A terminal in a wireless communication system, the terminal comprising:

a transceiver;
and
a controller configured to:
control the transceiver to receive, from a first base station of a first radio access technology (RAT), first configuration information on a measurement, the first configuration information including first information on a first threshold for identifying whether to perform the measurement and second information on a measurement object,
identify a RAT of a frequency to be measured based on the second information,
in case that the identified RAT of the frequency is the first RAT, identify whether a reference signal received power (RSRP) for a primary cell (PCell) of the first base station is lower than the first threshold based on the first information and perform the measurement on the frequency of the first RAT based on the RSRP being lower than the first threshold, and
in case that the identified RAT of the frequency is a second RAT, perform the measurement on the frequency of the second RAT, based on the second RAT being indicated in the second information.
