Title:
RANDOM ACCESS COLLISION DETECTION POSTPROCESSING METHOD FOR IMPROVING USER ACCESS RATE
Document Type and Number:
WIPO Patent Application WO/2007/065291
Kind Code:
A1
Abstract:
A random access collision detection postprocessing method for improving user
access rate including the steps: base station operates received random access
signal to obtain corresponding correlation peak window, front window and back
window and determines the pseudorandom sequence code selected by access user
terminal and then said base station decides whether the taps satisfying collision
decision condition exists out of correlation peak window or not, if not, it decides
that said pseudorandom sequence code access is successful; otherwise it decides
that the collision exists in pseudorandom sequence code access records all taps
positions satisfying collision decision condition and detects whether identical
collision occurs again or not, and if it is, it decides that said collision is caused
by individual user multipath by oneself, and that said pseudorandom sequence
code access is successful; otherwise it decides that multi-user access collision
exists. Said method can improve greatly user access rate without reducing collision
detection probability thereby enhance performance and treatment efficiency
in mobile communication system.
