Method and apparatus for transmission and reception of data in communication system
The disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies.
1. A method performed by a terminal in a communication system, the method comprising:
identifying a counterpart of a communication of the terminal as another terminal;
obtaining at least one parameter for identifying a data rate for the communication; and
identifying the data rate based on the at least one parameter and following equation:

a transceiver; and
a controller coupled with the transceiver and configured to:
identify a counterpart of a communication of the terminal as another terminal,
obtain at least one parameter for identifying a data rate for the communication, and
identify the data rate based on the at least one parameter and following equation:
