Abstract

A method and apparatus may be configured to monitor a first channel allocated to proximity-based services within a cluster. The method may also include transmitting, if the user device is not receiving transmissions on the first channel, an indication that the receiving user device is not receiving transmissions on the first channel allocated to the proximity-based services within the cluster. The method may also include receiving an indication of a second channel allocated to the proximity-based services within the cluster.

Claims

1. A method, comprising:

monitoring, by a receiving user device, a first channel allocated to proximity-based services within a cluster;

transmitting, if the user device is not receiving transmissions on the first channel, an indication that the receiving user device is not receiving transmissions on the first channel allocated to the proximity-based services within the cluster; and

receiving an indication of a second channel allocated to the proximity-based services within the cluster.

2. The method according to claim 1, wherein the second channel allocated to the proximity-based services within the cluster is a relaying channel for transmissions of a cluster head of the cluster.

3. The method according to claim 1, wherein the indication is transmitted to a cluster head of the cluster.

4. The method according to claim 1, further comprising:

monitoring at least one of the following;

the first channel allocated to the proximity-based services within the cluster and the second channel allocated to the proximity-based services within the cluster.

5. The method according to claim 1, further comprising:

monitoring the first channel allocated to the proximity-based services within the cluster and the second channel allocated to the proximity-based services within the cluster; and

determining at least one of the monitored channels to be used for reception.

6. The method according to claim 1, wherein, after the indication of the second channel allocated to the proximity-based services within the cluster is received, the method further comprises:

transmitting an indication that the second channel is not needed anymore, if transmissions are received on the first channel allocated to the proximity-based services within the cluster.

7. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to

monitor a first channel allocated to proximity-based services within a cluster;

transmit, if the apparatus is not receiving transmissions on the first channel, an indication that the receiving user device is not receiving transmissions on the first channel allocated to the proximity-based services within the cluster; and

receive an indication of a second channel allocated to the proximity-based services within the cluster.

8. The apparatus according to claim 7, wherein the second channel allocated to the proximity-based services within the cluster is a relaying channel for transmissions of a cluster head of the cluster.

9. The apparatus according to claim 7, wherein the indication is transmitted to a cluster head of the cluster.

10. The apparatus according to claim 7, wherein the apparatus is further caused to monitor at least one of the following:

the first channel allocated to the proximity-based services within the cluster and the second channel allocated to the proximity-based services within the cluster.

11. The apparatus according to claim 7, wherein the apparatus is further caused to:

monitor the first channel allocated to the proximity-based services within the cluster and the second channel allocated to the proximity-based services within the cluster; and

determine at least one of the monitored channels to be used for reception.

12. The apparatus according to claim 7, wherein the apparatus is, after the indication of the second channel allocated to the proximity-based services within the cluster is received, further caused to:

transmit an indication that the second channel is not needed anymore, if transmissions are received on the first channel allocated to the proximity-based services within the cluster.

13. A method, comprising:

receiving an indication that a receiving user device is not receiving transmissions on a channel allocated for proximity-based services within a cluster;

monitoring the channel allocated for the proximity-based services within a cluster and whether the channel is not usable for the receiving user device; and

providing relaying services for proximity-based service transmissions to the receiving user device.

14. The method according to claim 13, further comprising:

providing the relaying services to at least one cluster member other than the receiving user device.

15. The method according to claim 13, wherein the providing of the relaying services further comprises allocating a channel for the relaying services.

16. The method according to claim 13, wherein the providing of the relaying services further comprises allocating a channel for the relaying services, the method further comprising:

receiving an indication that transmissions are received on the channel allocated for proximity-based services, and

releasing the channel allocated for the relaying services.

17. The method according to claim 13, further comprising:

providing the relaying services by using groupcasting and/or broadcasting.

18. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to;

receive an indication that a receiving user device is not receiving transmissions on a channel allocated for proximity-based services within a cluster;

monitor the channel allocated for the proximity-based services within a cluster and whether the channel is not usable for the receiving user device; and

provide relaying services for proximity-based service transmissions to the receiving user device.

19. The apparatus according to claim 18, wherein the apparatus is further caused to provide the relaying services to at least one cluster member other than the receiving user device.

20. The apparatus according to claim 18, wherein the providing of the relaying services further comprises allocating a channel for the relaying services.

21. The apparatus according to claim 18, wherein the providing of the relaying services further comprises allocating a channel for the relaying services, the apparatus is further caused to:

receive an indication that transmissions are received on the channel allocated for proximity-based services, and

release the channel allocated for the relaying services.

22. The apparatus according to claim 18, wherein the apparatus is further caused to:

provide the relaying services by using groupcasting and/or broadcasting.
