Abstract

Provided are a method and an apparatus for processing uplink data. In particular, a method of a terminal for processing uplink data may include receiving configuration information for indicating uplink transmission configuration for an LTE-WLAN Aggregation (LWA) bearer from a base station; determining an uplink transmission path for the LWA bearer based on the configuration information and a transmittable data amount; and transmitting uplink data to the base station through the determined uplink transmission path, wherein the LWA bearer is a bearer configured to transmit the uplink data using at least one of a base station radio resource and a Wireless Local Area Network (WLAN) radio resource.

First claim

The invention claimed is:

1. A method of processing uplink data by a terminal, the method comprising:
receiving configuration information for indicating uplink transmission configuration for an LTE-WLAN Aggregation (LWA) bearer from a base station;
determining an uplink transmission path for the LWA bearer based on the configuration information and a transmittable data amount; and
transmitting uplink data to the base station through the determined uplink transmission path,
wherein the LWA bearer is a bearer configured to transmit the uplink data using at least one of a base station radio resource and a Wireless Local Area Network (WLAN) radio resource, and
wherein the determining of a transmission path comprises setting the uplink transmittable data amount as 0 and reporting to an MAC entity set to use the base station resource when the uplink transmittable data is less than the threshold value, and when the path assignment information indicates the WLAN radio resource to use for uplink data transmission.

2. The method of claim 1 , wherein the configuration information includes at least one of path assignment information for indicating an uplink transmission path of the LWA bearer and a threshold value.

3. The method of claim 2 , wherein the determining of a transmission path comprises determining the uplink transmission path in accordance with a result of comparing the uplink transmittable data amount with the threshold value.

4. The method of claim 2 , wherein the determining of a transmission path comprises determining the uplink transmission path based on the path assignment information when the uplink transmittable data amount is less than the threshold value.

5. The method of claim 1 , wherein the determining of a transmission path comprises reporting the uplink transmittable data amount to a Medium Access Control (MAC) entity set to use the base station radio resource when the uplink transmittable data is greater than the threshold value.

6. A method of receiving uplink data by a base station, the method comprising:
transmitting configuration information for indicating uplink transmission configuration for an LTE-WLAN Aggregation (LWA) bearer to a terminal; and
receiving uplink data through an uplink transmission path for the LWA bearer, where the uplink transmission path is determined based on the configuration information and an uplink transmittable data amount of the terminal,
wherein the configuration information includes at least one of path assignment information for indicating the uplink transmission path of the LWA bearer and a threshold value, and
the LWA bearer is a bearer configured to receive the uplink data using at least one of a base station radio resource and a Wireless Local Area Network (WLAN) radio resource, and
wherein the terminal is configured to determine the uplink transmission path to set the uplink transmittable data amount as 0 and report to an MAC entity set to use the base station resource when the uplink transmittable data amount is less than the threshold value and when the path assignment information indicates the WLAN radio resource to use for uplink data transmission.

7. The method of claim 6 , wherein the terminal is configured to determine the uplink transmission path in accordance with a result of comparing the uplink transmittable data amount with the threshold value.

8. The method of claim 6 , wherein the terminal is configured to determine the uplink transmission path based on the path assignment information when the uplink transmittable data amount is less than the threshold value.

9. The method of claim 6 , wherein the terminal is configured to determine the uplink transmission path to use the base station radio resource or the WLAN radio resource when the uplink transmittable data amount is greater than the threshold value.

10. A terminal for processing uplink data, the terminal comprising:
a receiver configured to receive configuration information for indicating uplink transmission configuration for an LTE-WLAN Aggregation (LWA) bearer from a base station;
a controller configured to determine an uplink transmission path for the LWA bearer based on the configuration information and a transmittable data amount; and
a transmitter configured to transmit uplink data to the base station through the determined uplink transmission path,
wherein the LWA bearer is a bearer configured to transmit the uplink data using at least one of a base station radio resource and a Wireless Local Area Network (WLAN) radio resource, and
wherein the controller is configured to determine the uplink transmission path to set the uplink transmittable data amount as 0 and report to an MAC entity set to use the base station resource when the uplink transmittable data amount is less than the threshold value and when the path assignment information indicates the WLAN radio resource to use for uplink data transmission.

11. The terminal of claim 10 , wherein the configuration information includes at least one of path assignment information for indicating an uplink transmission path of the LWA bearer and a threshold value.

12. The terminal of claim 11 , wherein the controller is configured to determine the uplink transmission path in accordance with a result of comparing the uplink transmittable data amount with the threshold value.

13. The terminal of claim 11 , wherein the controller is configured to determine the uplink transmission path based on the path assignment information when the uplink transmittable data amount is less than the threshold value.

14. The terminal of claim 10 , wherein the controller is configured to determine the uplink transmission path to transmit the uplink transmittable data to a Medium Access Control (MAC) entity set to use the base station radio resource when the uplink transmittable data amount is greater than the threshold value.
