Abstract

The 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. A method for transmitting information in a communication system is provided. The method includes receiving information for allocating at least two transmission resources, allocating at least two transmission resources, identifying a data unit corresponding to at least one logical channel, determining a size of the data unit, which is to be transmitted based on a size of the allocated at least two transmission resources, and transmitting data to a receiver based on the determined size of the data unit.

Claims8

Dependent claims

A method by a transmitter to transmit information in a communication system, the method comprising:

receiving information for allocating at least two transmission resources;
determining whether a transmission time interval (TTI) or a numerology corresponding to the at least two transmission resources are the same;
identifying at least one data unit corresponding to a plurality of logical channel;
determining each size of each data unit corresponding to each of the plurality of logical channel to be transmitted based on a total size of the at least two transmission resources, in case that the TTI or the numerology corresponding to the at least two transmission resources are the same;
allocating the at least one data unit to the at least two transmission resources based on the size of the data unit to be transmitted in the plurality of logical channel,
wherein a data unit allocable without segmentation among the at least one data unit is allocated to the at least two transmission resources based on the size of the data unit to be transmitted in the plurality of logical channel;
allocating data to the plurality of the logical channel based on each size of each data unit and the total size of the at least two transmission resources;
segmenting a data unit of data units not allocated to the at least two transmission resources based on a size of a transmission resource with a smallest size;
and
transmitting the data to a receiver.
