Introduction

C#&A is a comple' radio communication system $ith many

functions and in6ol6ed in radio parameters.

Radio communication system includes normal cell operation and

U8 call processes. U8 call process is closely related to radio

resource management from start to end; so C#&A radio

parameters can be classified as follo$s according to purpose.

Common signal channel parameters of cell

he )rotocol of radio communication system has been

impro6ing and de6eloping continuously due to subscribers

increasing requirements to ser6ice quality; so the radio

Basic principle

After introducing /+#)A; the ma'imum different bet$een /+-

)#+C/ and #)C/ is that /+-)#+C/ has no concept on macro

di6ersity; but its follo$ing #)C/ has the macro di6ersity

concept.

1 . /+#)As hando6er characteristic

he physics channel related to /+-#+C/ does not support

the soft hando6erD Because the code resources consumed

by /+-#+C/ are relati6ely many; and /+-#+C/

transmission is based on the grouping dispatch; it cannot

guarantee that many cells can transmit data for one

subscriber at the same time.

/+-#+C/ supports fast cell selectionD +elect the cell $ith

the best channel condition to take as /+-#+C/s ser6ing

cell; in order to guarantee the data continuity and high

data throughput.

Follo$ing #)C/ supports the soft hando6er.

the same frequency /+-#+C/s ser6ing cell change.

Under same frequency; $hen the hando6er e6ent among

frequencies occurs; conduct the different frequency /+-#+C/s

ser6ing cell change.

Because there is also different support attribute bet$een

ser6ing cell and goal cell; the receding from /+-#+C/ to #C/

$ill be follo$ed during hando6er.

f it is soft hando6er; then it is necessary to conduct the

reconfiguration to the multilink of mass macrodi6ersity. f it is

hard hando6er; then the hard hando6er $ill be follo$ed $ith
