PILOT SIGNAL ENHANCEMENTS FOR A WIRELESS COMMUNICATION SYSTEM |
摘要 |
In a method and apparatus suitable to convey timely information for facilitating accurate reception of transmitted data, a pilot signal is modulated to convey information. The information may facilitate efficient interpretation of an associated traffic signal. Modulation of a pilot signal frame may be limited to ensure early detection, and/or to minimize impairment of pilot functionality. In one embodiment, a Secondary Pilot Channel (SPICH) is transmitted at one of several selectable power levels to boost effectiveness of a phase reference, and is modulated to indicate the selected level. Such timely information enable prompt optimal combining of the SPICH with a primary Pilot Channel (PICH), and/or permits processing efficiencies for an associated traffic channel. Pilot signal frames may be transmitted at a predetermined level during a detection preamble portion of a frame to endure accurate and early detection, and at a more optimal level thereafter. |
