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.

Claims

1. A method by a terminal, comprising:

identifying at least one logical channel for an uplink transmission, based on a first time duration for each logical channel and a second time duration 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 from the at least one logical channel based on the allocation of the uplink resources.

2. The method of claim 1, wherein the first time duration for each logical channel includes a maximum time duration allowed for transmission for each logical channel.

3. The method of claim 2, wherein identifying of the at least one logical channel comprises:

determining whether each maximum time duration for the at least one logical channel is larger than or equal to the second time duration for the uplink resources; and

selecting the at least one logical channel for the uplink transmission if each maximum time duration for the at least one logical channel is larger than or equal to the second time duration for the uplink resources.

4. The method of claim 1, further comprising:

receiving a first message for configuring a logical channel, the first message including first information on the first time duration for the logical channel.

5. The method of claim 1, further comprising:

receiving a second message for allocating the uplink resources, the second message including second information on the second time duration for the uplink resources.

6. 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.

7. A terminal, comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to;

identify at least one logical channel for an uplink transmission, based on a first time duration for each logical channel and a second time duration 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 from the at least one logical channel based on the allocation of the uplink resources.

8. The terminal of claim 7, wherein the first time duration for each logical channel includes a maximum time duration allowed for transmission for each logical channel.

9. The terminal of claim 8, wherein the controller is configured to control to:

determine whether each maximum time duration for the at least one logical channel is larger than or equal to the second time duration for the uplink resources; and

select the at least one logical channel for the uplink transmission if each maximum time duration for the at least one logical channel is larger than or equal to the second time duration for the uplink resources.

10. The terminal of claim 7, wherein the controller is further configured to control to:

receive a first message for configuring a logical channel, the first message including first information on the first time duration for the logical channel.

11. The terminal of claim 7, wherein the controller is further configured to control to:

receive a second message for allocating the uplink resources, the second message including second information on the second time duration for the uplink resources.

12. The terminal of claim 7, 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.
