Abstract

Systems and methods of handling satellite channel and LTE coexistence are provided. A first device can identify at least one first frequency band. The first device can determine that at least one second frequency band of a plurality of second frequency bands overlaps with the at least one first frequency band. In response to determining that the at least one second frequency band overlaps with the at least one first frequency band, the first device transmits a message including an identifier of the first device and an indication of the at least one second frequency band to a second device. The second device receives the message. The second device, in response to receiving a channel request from the first device, allocates, from the plurality of second frequency bands, a second frequency band different from the at least one second frequency band.

First claim

1 .- 20 . (canceled)

21 . A device, comprising:
one or more processors, one or more circuits, or any combination thereof configured to: identify at least one first frequency band; responsive to identifying the at least one first frequency band, transmit a plurality of channel requests to another device; receive, from the another device, allocation of a maximum number of second frequency bands that are available for the another device to allocate after transmitting the plurality of channel requests to the another device; and determine that at least one second frequency band among the second frequency bands allocated by the another device overlaps with the at least one first frequency band identified by the device.

22 . The device of claim 21 , wherein the at least one first frequency band comprises a Long-Term Evolution (LTE) frequency band, and the at least one second frequency band comprises a transponder frequency band.

23 . The device of claim 21 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
responsive to determining that the at least one second frequency band overlaps with the at least one first frequency band, indicate that the at least one second frequency band is in-use by the device.

24 . The device of claim 21 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
responsive to determining that the at least one second frequency band overlaps with the at least one first frequency band, indicate that the at least one second frequency band is in-use by the device without decoding a stream associated with the at least one second frequency band.

25 . The device of claim 21 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
identify the at least one first frequency band by scanning first frequency bands at a boot time of the device.

26 . The device of claim 21 , wherein the allocation of the maximum number of the second frequency bands that are available for the another device to allocate is in response to the plurality of channel requests made by the device.

27 . The device of claim 23 , wherein the at least one second frequency band is indicated as in-use at a boot time of the device.

28 . The device of claim 27 , wherein the boot time is a first boot time, and the at least one second frequency band is indicated as in-use until a second boot time of the device.

29 . A device comprising:
one or more processors, one or more circuits, or any combination thereof configured to: identify at least one first frequency band; determine that the at least one first frequency band overlaps with at least one second frequency band among a plurality of second frequency bands; transmit, to another device, a first message comprising an indication of the at least one second frequency band; identify another first frequency band different from the at least one first frequency band; determine that the another first frequency band overlaps with another second frequency band among the plurality of second frequency bands, the another second frequency band different from the at least one second frequency band; and transmit, to the another device, a second message comprising an indication of the another second frequency band.

30 . The device of claim 29 , wherein the at least one first frequency band comprises a Long-Term Evolution (LTE) frequency band, and the at least one second frequency band comprises a transponder frequency band.

31 . The device of claim 29 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
identify the at least one first frequency band by scanning first frequency bands associated with a Long-Term Evolution (LTE) module.

32 . The device of claim 29 , wherein the device comprises a set-top box (STB), and the another device comprises an Out Door Unit (ODU).

33 . The device of claim 29 , wherein the first message is transmitted to the another device via a coax cable.

34 . A device comprising:
one or more processors, one or more circuits, or any combination thereof configured to: receive, from another device, a first message comprising an indication of at least one second frequency band, the at least one second frequency band overlapping with at least one first frequency band; and in response to receiving the first message comprising the indication of the at least one second frequency band, store the indication of the at least one second frequency band in a list of overlapping second frequency bands, the at least one second frequency band being associated with the another device.

35 . The device of claim 34 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
in response to receiving a channel request from the another device, allocate a second frequency band different from the at least one second frequency band.

36 . The device of claim 34 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
receive a second message from the another device, the second message comprising an indication of another second frequency band different from the at least one second frequency band; and update the list of overlapping second frequency bands in response to receiving the second message.

37 . The device of claim 34 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
receive a second message from the another device, the second message indicating no overlapping second frequency band associated with the another device; and update the list of overlapping second frequency bands by removing the indication of the at least one second frequency band from the list of overlapping second frequency bands.

38 . The device of claim 34 , wherein each second frequency band in the list of overlapping second frequency bands is associated with at least one device, the at least one device including the another device.

39 . The device of claim 34 , further comprising the one or more processors, the one or more circuits, or the any combination thereof configured to:
receive a channel request from a device other than the another device; determine that the device other than the another device is not associated with second frequency bands in the list of overlapping second frequency bands; and allocate a next available second frequency band from a plurality of second frequency bands responsive to the channel request.

40 . The device of claim 34 , wherein the at least one first frequency band comprises a Long-Term Evolution (LTE) frequency band, and the at least one second frequency band comprises a transponder frequency band.
