WIRELESS COMMUNICATIONS RECEIVER EMPLOYING QUICK PAGING CHANNEL SYMBOLS |
摘要 |
A system for efficiently employing a quick paging channel signal to determine the presence of a forthcoming primary paging channel in a wireless communications system employing a quick paging channel and a primary paging channel. The system includes a first mechanism for selectively processing a first quick paging channel symbol and/or a second quick paging channel symbol of a received signal based on a first decision parameter and/or a second decision parameter and providing a first indication in response thereto. A second mechanism processes the first quick paging channel symbol in response to the first indication and provides a second indication in response thereto indicating whether a forthcoming primary paging channel signal should be received and processed. A third mechanism processes the second quick paging channel symbol in response to the first indication and the second indication and provides a third indication in response thereto specifying whether the primary paging channel should be received an processed. In a specific embodiment, the system is adapted for use with a mobile station and further includes a fourth mechanism for selectively employing the third mechanism when the second indication does not indicate that the forthcoming primary paging channel should be received and processed. The first decision parameter <i>CSI1</i> is representative of a quality of a signal environment through which the received signal propagates and is described by the equation (I) where <i>E</i>pilot1 represents the normalized pilot energy of a portion of the pilot signal associated with the first quick paging symbol, and <i>Î</i>o1 represents a total energy of a portion of the received signal associated with the first quick paging symbol. |
