Abstract

In a non-limiting and exemplary embodiment, a method is provided for arranging multi-channel wireless communications, comprising: determining a first dedicated channel for a first apparatus from a set of channels, receiving an indication of a second dedicated channel for a second apparatus, and communicating with the second apparatus on the first dedicated channel and on the second dedicated channel, wherein a first communications event on the first dedicated channel and a second communication event at the second dedicated channel are carried out at least partially simultaneously.

First claim

The invention claimed is:

1. A method, comprising:
determining, by a first apparatus, a first dedicated channel of the first apparatus from a set of channels;
receiving, by the first apparatus, an indication of a second dedicated channel of a second apparatus, wherein the indication of the second dedicated channel is received in a broadcast message for local wireless device presence advertisement or a response to a broadcast device discovery request; and
transmitting, by the first apparatus, data frames to the second apparatus at least partially simultaneously on the first dedicated channel and on the second dedicated channel, wherein the first apparatus and the second apparatus are mobile terminals,
wherein the second dedicated channel of the second apparatus is not a dedicated channel of the first apparatus and the first dedicated channel of the first apparatus is not a dedicated channel of the second apparatus.

2. The method of claim 1 , further comprising transmitting an indication of the first dedicated channel to the second apparatus.

3. The method of claim 1 , further comprising:
selecting the second dedicated channel for communication with the second apparatus based on receiving the broadcast message on the second dedicated channel.

4. The method of claim 3 , wherein the broadcast message comprises a beacon frame.

5. The method of claim 1 , wherein the first dedicated channel is determined based on sensed channel utilization.

6. The method of claim 1 , wherein the first apparatus and the second apparatus are mesh points.

7. The method of claim 6 , wherein the first apparatus maintains information on dedicated channels of mesh points with which the first apparatus has peered, and the first apparatus monitors the first dedicated channel and the dedicated channels of the mesh points with which the first apparatus has peered.

8. 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 to, with the at least one processor, cause the apparatus at least to:
determine a first dedicated channel of the apparatus from a set of channels,
receive an indication of a second dedicated channel of a second apparatus, wherein the indication of the second dedicated channel is received in a broadcast message for local wireless device presence advertisement or a response to a broadcast device discovery request, and
transmit data frames to the second apparatus at least partially simultaneously on the first dedicated channel and on the second dedicated channel, wherein the apparatus and the second apparatus are mobile terminals, wherein the second dedicated channel of the second apparatus is not a dedicated channel of the apparatus and the first dedicated channel of the apparatus is not a dedicated channel of the second apparatus.

9. The apparatus of claim 8 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to: transmit an indication of the first dedicated channel to the second apparatus.

10. The apparatus of claim 8 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:
select the second dedicated channel for communication with the second apparatus based on receiving the broadcast message on the second dedicated channel.

11. The apparatus of claim 10 , wherein the broadcast message comprises a beacon frame.

12. The apparatus of claim 8 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to: determine the first dedicated channel based on sensed channel utilization.

13. The apparatus of claim 8 , wherein the apparatus and the second apparatus are mesh points.

14. The apparatus of claim 8 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to: maintain information on dedicated channels of mesh points with which the apparatus has peered, and
the apparatus is configured to monitor the first dedicated channel and the dedicated channels of the mesh points with which the apparatus has peered.

15. The apparatus claim 8 , wherein the apparatus is a communications device comprising a transceiver for communicating according to an IEEE 802.11ac standard, and the channels are IEEE 802.11ac channels.
