LTE operation in white spaces

摘要

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).

主权项

1. A method for reassigning a secondary communication channel, comprising:
operating one or more secondary communication channels having a first priority at a 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 spaces, 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 spaces; and reassigning the one or more secondary communication channels from the white space to at least one of the one or more unused sections of the white space.
