Abstract

An electronic device may receive aggregated data including a plurality of data blocks via a first link among a plurality of wireless communication links from a second electronic device connected to the electronic device via the plurality of wireless communication links, may transmit information indicating a failure to receive a target block among the plurality of data blocks to the second electronic device via a second link among the plurality of wireless communication links based on reception of the target block failing, and may receive the target block from the second electronic device via the second link.

First claim

What is claimed is:

1. An electronic device comprising:
a communication module comprising communication circuitry configured to exchange data with an external device;
at least one processor comprising processing circuitry; and
memory,
wherein the memory stores instructions that, when executed by the at least one processor, cause the electronic device to:
receive aggregated data via a first link among a plurality of wireless communication links from a second electronic device connected to the electronic device via the plurality of wireless communication links, the aggregated data comprising a plurality of data blocks;
transmit to the second electronic device via a second link among the plurality of wireless communication links, before a last data block of the aggregated data is received via the first link, information indicating a failure to receive a target block among the plurality of data blocks based on reception of the target block failing; and
receive the target block from the second electronic device via the second link.

2. The electronic device of claim 1 , wherein the second link is used for receiving only the blocks among the plurality of data blocks that were not received via the first link.

3. The electronic device of claim 1 , wherein when executed by the at least one processor, the instructions cause the electronic device to:
operate a preset timer based on the reception of the target block failing;
transmit information indicating a failure to receive a second target block and the target block to the second electronic device via the second link, based on reception of the second target block failing before the timer expires; and
receive the target block and the second target block from the second electronic device via the second link.

4. The electronic device of claim 3 , wherein when executed by the at least one processor, the instructions cause the electronic device to transmit the information indicating the failure to receive the target block to the second electronic device via the second link, based on reception of a block other than the target block not failing before the timer expires.

5. The electronic device of claim 1 , wherein when executed by the at least one processor, the instructions cause the electronic device to:
operate a preset timer based on the reception of the target block failing;
restart the timer based on reception of a second target block failing before the timer expires;
transmit information indicating a failure to receive the target block and the second target block to the second electronic device via the second link, based on reception of a block other than the target block and the second target block not failing before the timer expires; and
receive the target block and the second target block from the second electronic device via the second link.

6. The electronic device of claim 1 , wherein the first link and the second link are configured to share the memory for an access category (AC) or a traffic identification (TID) of the aggregated data.

7. The electronic device of claim 6 , wherein when executed by the at least one processor, the instructions cause the electronic device to arrange at least one data block received via the first link and the target block received via the second link in the memory based on sequence numbers.

8. The electronic device of claim 1 , wherein when executed by the at least one processor, the instructions cause the electronic device to:
determine whether the second link allows retransmission of a data block that fails to be received via the first link in a process of establishing the second link with the second electronic device; and
transmit the information indicating the failure to receive the target block to the second electronic device via the second link, based on the second link allowing the retransmission of the data block.

9. The electronic device of claim 8 , wherein information about whether the second link allows the retransmission of the data block that fails to be received is included in a beacon transmitted by the second electronic device.

10. The electronic device of claim 1 , wherein when executed by the at least one processor, the instructions cause the electronic device to:
determine a duration of a session for the reception of the target block based on the reception of the target block failing;
generate the information indicating the failure to receive the target block to include information about the duration of the session;
transmit the information indicating the failure to receive the target block to the second electronic device via the second link; and
receive the target block from the second electronic device via the second link during the duration of the session.

11. The electronic device of claim 10 , wherein when executed by the at least one processor, the instructions cause the electronic device to determine the duration of the session based on at least one of a quantity of data of the target block, a transmission rate of the first link, and a transmission rate of the second link.

12. An electronic device comprising:
a communication module comprising communication circuitry configured to exchange data with an external device;
at least one processor comprising processing circuitry; and
memory,
wherein the memory stores instructions that, when executed by the at least one processor, cause the electronic device to:
transmit aggregated data via a first link among a plurality of wireless communication links to a second electronic device connected to the electronic device via the plurality of wireless communication links, the aggregated data comprising a plurality of data blocks;
receive information indicating a failure to receive a target block among the plurality of data blocks from the second electronic device via a second link among the plurality of wireless communication links; and
transmit the target block to the second electronic device via the second link,

wherein the information indicating the failure to receive the target block is received from the second electronic device via the second link before a last data block of the aggregated data is transmitted to the second electronic device via the first link.

13. The electronic device of claim 12 , wherein the second link is used for receiving only the blocks among the plurality of data blocks that were not received via the first link.

14. The electronic device of claim 12 , wherein
the information indicating the failure to receive the target block comprises information about a duration of a session, and
wherein when executed by the at least one processor, the instructions cause the electronic device to transmit the target block to the second electronic device via the second link during the duration of the session.

15. The electronic device of claim 12 , wherein the first link and the second link are configured to share the memory for an access category (AC) or a traffic identification (TID) of the aggregated data.

16. The electronic device of claim 12 , wherein when executed by the at least one processor, the instructions cause the electronic device to:
determine whether the second link allows retransmission of a data block that fails to be received via the first link in a process of establishing the second link with the second electronic device; and
receive the information indicating the failure to receive the target block from the second electronic device via the second link, based on the second link allowing the retransmission of the data block.
