Appl. No.:

11/367498

Inventors:

Supratik Bhattacharjee - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04W 4/00

US Classification:

370329, 370278, 370252, 370528

Abstract:

A terminal communicates with a first wireless network and obtains a list of cells in a second wireless network to measure. The terminal operates in a compressed mode and receives multiple transmission gap pattern sequences for different measurement purposes, e. g. , RSSI measurements, BSIC identification, and BSIC re-confirmation. The terminal utilizes each transmission gap for its designated purpose or an alternate purpose. For each transmission gap, the designated purpose for the transmission gap is ascertained, and whether the transmission gap is usable for an alternate purpose is also determined based on at least one criterion. The transmission gap is used for the alternate purpose if the at least one criterion is satisfied and is used for the designated purpose otherwise. For example, a transmission gap designated for RSSI measurement may be used for BSIC identification, a transmission gap designed for BSIC identification or BSIC re-confirmation may be used for RSSI measurement, and so on.

International Classification:

H03D 1/06

US Classification:

375348

Abstract:

A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.
