LTE operation in white spaces
First Claim
1. A method for reassigning a contiguous secondary communication channel, comprising:
- operating one or more secondary communication channels having a first priority at a contiguous secondary frequency range within a white space having a continuous frequency range;
detecting an arrival of one or more primary user signals within the white space, wherein the primary user signals have a higher priority than the first priority and wherein the primary user signals have a primary frequency range that conflicts with the secondary frequency ranges and that provide for one or more unused sections of the white space; and
reassigning the one or more contiguous secondary communication channels from the white space to at least one of the one or more unused sections of the white space.

Abstract
One embodiment of the present invention relates to a method for efficient reassignment of a secondary communication channel (having a first priority) within a white space, upon arrival of a conflicting primary user signal (having a second priority higher than the first priority). In particular, the method comprises reassigning a secondary communication channel to unused portions of one or more white spaces remaining after the arrival of one or more primary users. For example, in one embodiment wherein one or more secondary communication channels are operated at contiguous secondary frequency ranges within a white space, a primary/incumbent user may arrive at a frequency range that conflicts with the secondary frequency range and that generates unused frequency portions of the white space(s). The secondary communication channel may be reassigned to the unused frequency portions of the white space (e.g., forming a non-contiguous secondary communication channel, forming a secondary communication channel having a reduced bandwidth).

1. A method for reassigning a contiguous secondary communication channel, comprising:
-
operating one or more secondary communication channels having a first priority at a contiguous secondary frequency range within a white space having a continuous frequency range; detecting an arrival of one or more primary user signals within the white space, wherein the primary user signals have a higher priority than the first priority and wherein the primary user signals have a primary frequency range that conflicts with the secondary frequency ranges and that provide for one or more unused sections of the white space; and reassigning the one or more contiguous secondary communication channels from the white space to at least one of the one or more unused sections of the white space. - View Dependent Claims (2, 3, 4)

5. A method for constructing a non-contiguous secondary communication channel, comprising:
-
operating one or more secondary communication channels having a first priority at a contiguous secondary frequency range within a white space; detecting an arrival of a primary user signal within the white space, wherein the primary user signal has a higher priority than the first priority and wherein the primary user signal has a primary frequency range that conflicts with the contiguous secondary frequency range and that provides for unused sections of the white space; and reassigning the one or more secondary communication channels to one or more non-contiguous secondary communication channels comprising non-contiguous frequency spectrums within the unused sections of the white space, which have a contiguous bandwidth smaller than the contiguous secondary frequency range. - View Dependent Claims (6, 7, 8, 9, 10)

11. A communication circuit, comprising:
-
a frequency reassignment circuit configured, upon arrival of a primary user signal within a white space having a continuous frequency range, to reassign a contiguous secondary communication channel, operating within the white space, to a non-contiguous secondary communication channel having a non-contiguous frequency spectrum within the white space; wherein the primary user signal has a first priority and the secondary communication channel has a second priority less than the first priority, and wherein the non-contiguous secondary communication channel is assigned to have frequencies that are different than a frequency range of the primary user signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
