Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure relates to a method for quickly and efficiently allocating uplink transmission resource to data of a terminal.

Description

technical field [0001] Various embodiments of the present disclosure relate to a method for allocating uplink transmission resources to data and transmitting the data in a mobile communication system. Background technique [0002] In order to meet the demand for wireless data services that has increased since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, 5G or pre-5G communication system is also called "super 4G network" or "post-LTE system". 5G communication systems are considered to be implemented in higher frequency (mmWave) frequency bands, such as the 60GHz band, in order to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (Full Dimensional MIMO, FD-MIMO), array antenna, analog beam Shaped, massive antenna technology is discussed...
