Abstract

A method comprising determining that interference may occur in a wireless network an apparatus is connected to, obtaining a first link that is of a first type, obtaining a second link that is of a second type, determining data to be transmitted from the apparatus to another apparatus connected to the wireless network, determining that a transmission occurs in the first link and transmitting the data in the second link, wherein the transmission in the first link has a longer duration than transmitting the data in the second link and the transmission in the first link and transmitting the data in the second link overlap in time.

First claim

The invention claimed is:

1. An apparatus, comprising:
at least one processor; and
at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
determine that interference may occur in a wireless network the apparatus is connected to, wherein determining that interference may occur in the wireless network the apparatus is connected to comprises detecting a jammer;
obtain a first link that is of a first type;
obtain a second link that is of a second type;
determine data to be transmitted to another apparatus connected to the wireless network;
determine that a transmission occurs in the first link; and
transmit the data in the second link during the transmission in the first link wherein the transmission in the first link has a longer duration than transmitting the data in the second link and the transmission in the first link and transmitting the data in the second link overlap in time, such that the transmitting the data in the second link is completed prior to completion of the transmission in the first link, and wherein the transmission in the first link comprises transmitting the data in the first link using a modulation and coding scheme that has a lower data rate than a modulation and coding scheme of the second link.

2. The apparatus according to claim 1 , wherein the apparatus operates in a multi-link mode and the first link and the second link are part of a multi-link operation.

3. The apparatus according to claim 1 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus to postpone channel access after detecting the jammer.

4. The apparatus according to claim 1 , wherein transmitting the data in the second link is initiated when the transmission in the first link is ongoing.

5. The apparatus according to claim 1 , wherein obtaining the first link and obtaining the second link are performed jointly.

6. The apparatus according to claim 1 , wherein the first link and the second link are obtained based, at least partly, on received signal strength, bandwidth aggregation opportunities or a guaranteeing condition associated with time.

7. The apparatus according to claim 1 , wherein the transmission occurring in the first link is caused by a further apparatus, which is different than the apparatus and the another apparatus.

8. The apparatus according to claim 7 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus to acquire a duration of the transmission occurring in the first link, that is caused by the further apparatus, and to determine the duration of transmitting the data in the second link based on the acquired duration of the transmission occurring in the first link.

9. The apparatus according to claim 1 , wherein the jammer is a reactive jammer.

10. The apparatus according to claim 9 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus to obtain at least one further link that is of the first type after determining that the jammer is capable of transmitting in a number of links that is higher than a determined number of links of the first type.

11. The apparatus according to claim 1 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus to obtain at least one further link that is of the first type.

12. A method, comprising:
determining that interference may occur in a wireless network an apparatus is connected to, wherein determining that interference may occur in the wireless network the apparatus is connected to comprises detecting a jammer;
obtaining a first link that is of a first type;
obtaining a second link that is of a second type;
determining data to be transmitted from the apparatus to another apparatus connected to the wireless network;
determining that a transmission occurs in the first link; and
transmitting the data in the second link during the transmission in the first link, wherein the transmission in the first link has a longer duration than transmitting the data in the second link and the transmission in the first link and transmitting the data in the second link overlap in time, such that the transmitting the data in the second link is completed prior to completion of the transmission in the first link, and wherein the transmission in the first link comprises transmitting the data in the first link using a modulation and coding scheme that has a lower data rate than a modulation and coding scheme of the second link.

13. The method according to claim 12 , wherein the method operates in a multi-link mode and the first link and the second link are part of a multi-link operation.

14. The method according to claim 12 , further comprising postponing channel access after detecting the jammer.

15. The method according to claim 12 , wherein transmitting the data in the second link is initiated when the transmission in the first link is ongoing.

16. The method according to claim 12 , wherein obtaining the first link and obtaining the second link are performed jointly.

17. The method according to claim 12 , wherein the first link and the second link are obtained based, at least partly, on received signal strength, bandwidth aggregation opportunities or a guaranteeing condition associated with time.

18. A non-transitory computer readable medium comprising program instructions for causing an apparatus to perform at least the following:
determining that interference may occur in a wireless network an apparatus is connected to, wherein determining that interference may occur in the wireless network the apparatus is connected to comprises detecting a jammer;
obtaining a first link that is of a first type;
obtaining a second link that is of a second type;
determining data to be transmitted from the apparatus to another apparatus connected to the wireless network;
determining that a transmission occurs in the first link; and
transmitting the data in the second link during the transmission in the first link, wherein the transmission in the first link has a longer duration than transmitting the data in the second link and the transmission in the first link and transmitting the data in the second link overlap in time, such that the transmitting the data in the second link is completed prior to completion of the transmission in the first link, and wherein the transmission in the first link comprises transmitting the data in the first link using a modulation and coding scheme that has a lower data rate than a modulation and coding scheme of the second link.
