Benefits of technology

[0008] Embodiments of the present invention provide for determining whether an insufficient guard band exists in a spectrum carrying potentially interfering signals and allocating a temporary guard band to spectrally separate the two signals, thereby reducing or preventing inter-signal interference.

Problems solved by technology

In some circumstances, a signal at one end of a block of spectrum may be interfered by a signal of the different type from a neighboring block of spectrum.
If the higher power signal spills over into the adjacent band, reception of signals within the band may be hampered.

Embodiment Construction

[0023] In the following description, reference is made to the accompanying drawings which illustrate several embodiments of the present invention. It is understood that other embodiments may be utilized and mechanical, compositional, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of the embodiments of the present invention is defined only by the claims of the issued patent.

[0024] Embodiments of the present invention provide for determining whether an insufficient guard band exists in a spectrum carrying potentially interfering signals and allocating a temporary guard band to spectrally separate the two signals, thereby reducing or preventing inter-signal interference. Some embodiments provide for systems communicating band allocations near a band edge. The system may be integrated with a neighboring system to pr...

Abstract

Embodiments of the present invention provide for determining whether an insufficient guard band exists in a spectrum carrying potentially interfering signals and allocating a temporary guard band to spectrally separate the two signals, thereby reducing or preventing inter-signal interference.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not applicable. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to communication systems and more particularly to guard bands between a first mode and a second mode of communication. [0004] 2. Description of the Related Art [0005] Wireless service providers are often provided one or more blocks of spectrum. Often one block of spectrum neighbors another block of spectrum carrying a different signal type. In some circumstances, a signal at one end of a block of spectrum may be interfered by a signal of the different type from a neighboring block of spectrum. For example, the different signal time may be transmitted with a much higher power. If the higher power signal spills over into the adjacent band, reception of signals within the band may be hampered. [0006] One solution to reduce interference between signals from neighboring blocks of spectrum is for a permanent guard band t...
