Abstract
Frequency spectrum of wireless transmission signals are allocated based on availability and regulatory requirements. To ensure transmission signals are within designated channel boundary, user equipment utilizes processing circuitry coupled to a transceiver to pre-compensate for estimated frequency shift at the time of transmissions. Certain guard bands are provided such that the actual transmission signals with the frequency pre-compensation are within the designated channel boundary. Additionally, or alternatively, the user equipment utilizes the processing circuitry to pre-compensate for estimated time shift based on a crystal drift using temperature measurement.
