Abstract

Methods and devices configured to perform wireless communications, the methods and devices configured to monitor a frequency band for one or more other Radio Access Technologies (RATs); determine one or more periods of a reduced interference with the one or more other RATs in one or more frequencies of the monitored frequency band; and communicate a first signal during the one or more periods in the more or more frequencies, and communicate a second signal in the frequency band based on the communication of the first signal.

First claim

What is claimed is:

1. A communication device configured to perform wireless communications, comprising:
a detector configured to monitor a frequency band for one or more other Radio Access Technologies (RATs);
a determiner configured to determine one or more periods of reduced interference with the one or more other RATs in one or more frequencies of the monitored frequency band; and
a communicator configured to communicate a first signal during the one or more periods of reduced interference in the one or more frequencies of the monitored frequency band, and communicate a second signal in the monitored frequency band based on the communication of the first signal, wherein the first signal is a control signal and the second signal is a data signal.

2. The communication device of claim 1 , wherein the communicator is configured to communicate the first signal and the second signal on different frequencies of the frequency band; and wherein the second signal is communicated during the one or more periods of reduced interference.

3. The communication device of claim 1 , wherein the first signal is an acknowledgment (ACK) signal.

4. The communication device of claim 1 , wherein the first signal is a negative acknowledgement (NACK) signal.

5. The communication device of claim 1 , wherein the determiner is configured to determine an energy for each of the one or more frequencies of the frequency band.

6. The communication device of claim 5 , wherein the determiner is configured to determine the one or more periods of reduced interference by comparing the energy of each of the respective frequencies of the one or more frequencies to a power threshold.

7. The communication device of claim 6 , wherein the determiner is configured to initiate a back off period on the respective frequency when the respective energy is greater than the power threshold.

8. The communication device of claim 7 , wherein the back off period is determined based on a frame length for the RAT corresponding to the first signal and the second signal.

9. A communication device configured to communicate via at least a first Radio Access Technology (RAT) and a second RAT, the communication device comprising:
a minislot determiner configured to determine a plurality of minislots for each slot of a plurality of slots in a wireless communication frame of the first RAT, wherein the duration of each of the plurality of minislots is based on a duration of communicating via the second RAT based on at least one second RAT communication protocol; and
a scheduler configured to schedule communications for the first RAT using the plurality of slots or the plurality of minislots, wherein communications for the first RAT are prevented during slots or minislots associated with communications for the second RAT based on the at least one second RAT communication protocol.

10. The communication device of claim 9 , wherein the duration of each of the minislots is a multiple of the duration of communicating via the second RAT based on the second RAT communication protocol, wherein the duration of communicating via the second RAT is a minimum duration according to the at least one second RAT communication protocol.

11. The communication device of claim 9 , wherein the scheduler is configured to schedule a substantially equal number of the plurality of slots or the plurality of minislots for communications of the first RAT and for communications of the second RAT.

12. The communication device of claim 9 , further comprising:
a sharer configured to share the schedule of the communications of the first RAT with a peer device.

13. A communication device comprising:
an acquirer configured to acquire radio link measurement information for each of a plurality of frequency bands;
a prioritizer configured to prioritize the plurality of frequency bands based on their respective radio link measurement information;
a preferred band determiner configured to determine a preferred band from the plurality of frequency bands by determining that at least one of the plurality of frequency bands fulfills a minimum requirement for sending an intended transmission; and
a distributor configured to distribute the intended transmission for communication based to the preferred band on the preferred band determiner's determination.

14. The communication device of claim 13 , wherein the radio link measurement information includes at least one of an available frequency; a maximum radio frequency (RF) output power; a power budget; bandwidth; band-specific power amplifier (PA) duty cycles; desired Quality of Service (QoS) information including at least one of data rate, latency, or jitter buffer; channel characteristics; regulatory requirements; or information about the reachability of one or more desired receivers.

15. The communication device of claim 13 , wherein the preferred band determiner is configured to determine the minimum requirement for the intended transmission based on a type of operation to be sent via the intended transmission or based on a maximum potential coverage of each of the plurality of frequency bands.

16. The communication device of claim 13 , further comprising:
a transceiver configured to receive radio link information for each of the plurality of frequency bands and transmitting the intended communication.

17. A communication device comprising:
a physical display configured to provide a discovery/mesh area of a graphical user interface; and
one or more processors configured to:
display via the discovery/mesh area of the graphical user interface, a plurality of nodes, wherein a first node of the plurality of nodes represents the communication device; and
display via the discovery/mesh area of the graphical user interface one or more node connectors, wherein the one or more node connectors are configured between the first node and one or more peer nodes from the plurality of nodes.

18. The communication device of claim 17 , wherein the one or more processors are configured to display one or more secondary node connectors between at least one of the one or more peer nodes and one or more further nodes of the plurality of nodes, wherein each of the one or more further nodes represents a respective further device, wherein each of the secondary node connectors is a line representing a wireless link between the peer device and the respective further device.

19. The communication device of 17 , wherein the one or more processors are configured to display via the physical display a mesh toggle wherein the discovery/mesh area of the graphical user interface includes the mesh toggle.

20. The communication device of 17 , wherein the one or more processors are configured to select at least one of the plurality of nodes; and provide via the physical display a node information display area associated with the selected node.
