(QCOM WCDMA SOFT HANDOFF PATENT)
METHOD AND APPARATUS FOR SOFT HANDOFF IN A CDMA COMMUNICATION SYSTEM
Patent Number: WO0191338
Publication date: 2001-11-29
Inventor(s): WILLENEGGER SERGE; GRILLI FRANCESCO; TERASAWA DAISUKE
Applicant(s):: QUALCOMM INC (US)
Requested Patent: WO0191338
Application Number: WO2001US16225 20010518
Priority Number(s): US20000576063 20000522
IPC Classification: H04B7/26 ; H04J3/06
EC Classification:
Equivalents:

Abstract
--------------------------------------------------------------------------------
A novel and improved method and apparatus, in a WCDMA communication system (100),
for informing a mobile station (101) of a downlink data frame time offset by determining
the downlink data frame time offset, and transmitting the downlink data frame time
offset via an Active Set Update message transmitted from a cell (102 or 103) to mobile
station (101). Once an Active Set Update message is received, the data frame time
offset information is provided to a timing block (201) which may determine data frame
boundary of each downlink signal. Timing block (201) may then adjust the PN sequence
timing corresponding to the downlink signal associated with the data frame time offset
such that corresponding data symbols in each data frame are correctly soft combined in
a combiner (210).
