Method and apparatus for transmitting data in a mobile communication system
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.
1. A method by a terminal, comprising:
configuring a plurality of time durations for uplink transmission;
receiving a first message for allocating uplink resources, the first message including information indicating a time duration, allowed for the uplink resources, among the plurality of time durations;
identifying at least one logical channel satisfying a condition based on a comparison between maximum time duration allowed for each logical channel and the time duration allowed for uplink resources;
allocating the uplink resources to the identified at least one logical channel based on a predetermined order of priority; and
transmitting data on the uplink resources, the data being generated based on the at least one logical channel.
2. The method of claim 1 , wherein identifying of the at least one logical channel comprises:
selecting the at least one logical channel if each maximum time duration for the at least one logical channel is larger than or equal to the time duration for the uplink resources.
3. The method of claim 1 , further comprising:
receiving a second message for configuring one or more logical channels, the second message including the maximum time duration allowed for each logical channel.
4. The method of claim 1 , wherein a logical channel for an uplink common control channel (UL-CCCH) is higher priority than a logical channel for a buffer status report (BSR) or a power headroom report (PHR), based on the predetermined order of priority.
5. A terminal, comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
configure a plurality of time durations for uplink transmission,
receive a first message for allocating uplink resources, the first message including information indicating a time duration allowed for the uplink resources, among the plurality of time durations,
identify at least one logical channel satisfying a condition based on a comparison between maximum time duration allowed for each logical channel and the time duration allowed for uplink resources,
allocate the uplink resources to the identified at least one logical channel based on a predetermined order of priority, and
transmit data on the uplink resources, the data being generated based on the at least one logical channel.
6. The terminal of claim 5 , wherein the controller is configured to control to:
select the at least one logical channel if each maximum time duration for the at least one logical channel is larger than or equal to the time duration for the uplink resources.
7. The terminal of claim 5 , wherein the controller is further configured to control to:
receive a second message for configuring one or more logical channels, the second message including the maximum time duration allowed for each logical channel.
8. The terminal of claim 5 , wherein a logical channel for an uplink common control channel (UL-CCCH) is higher priority than a logical channel for a buffer status report (BSR) or a power headroom report (PHR), based on the predetermined order of priority.
