Spectrum Allocation for Base Station

摘要

Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.

主权项

1. A base station, comprising:
a radio transceiver; a spectrum virtualization module configured to exchange physical baseband signals with the radio transceiver, the spectrum virtualization module further configured to perform baseband signal shaping to convert the physical baseband signals into and from virtual baseband signals generated according to one or more virtual frequency bands of a wireless transmission protocol of the spectrum virtualization module; and a spectrum manager including a decision module, the decision module configured to determine, based on one or more transmission policies, a spectrum allocation that maps one or more physical frequency bands available in a geographic area of the base station to the one or more virtual frequency bands in accordance with the wireless transmission protocol for baseband signal shaping by the spectrum virtualization module.
