LG-TM250
Idle Handoff. The act of transferring reception of the Paging Channel from one bass station to another, when
the mobile station is in the Mobile Station Idle State.
Implicit Registration. A registrationachieved by a successful transmission of an origination or page response
on the Access Channel.
Interleaving. The process of permuting a sequence of symbols.
kHz. Kilohertz (10 3
Hertz).
ksps. Kilo-symbols per second (10 3
symbols per second).
Layer 1. See Physical Layer.
Layer 2. Layer 2 provides for the correct transmission and reception of signaling messages, including partial
duplicate detection. See also Layering and Layer 3.
Layer 3. Layer 3 provides the control of the cellular telephone systems. Signaling messages originate and
terminate at layer 3. See also Layering and Layer 2.
Local Control. An optional mobile station feature used to perform manufacturer-specific functions.
2
A PN sequence with period 24 -1 that is used for scrambling on the Forward CDMA Channel and spreading on
the Reverse CDMA Channel. The long code uniquely identifies a mobile station on both the Reverse Traffic
Channel and the Forward Traffic Channel. The long code provides limited privacy. The long code also
separates multiple Access Channels on the same CDMA channel. See also Public Long Code and Private Long
Code.
Long Code Mask. A 42-bit binary number that creates the unique identity of the long code. See also Public
Long Code, Private Long Code, Public Long Code Mask, and Private Long Code Mask.
LSB. Least significant bit.
Maximal Length Sequence (m-Sequence). A binary sequence of period 2n-1, n a positive integer, with no
internal periodicities. A maximal length sequence can be generated by a tapped n-bit shift register with linear
feedback.
Mcps. Megachips per second (10 6
chips per second).
Mean Input Power. The total received calorimetric power measured in a specified bandwidth at the antenna
connector, including all internal and external signal and noise sources.
Mean Output Power. The total transmitted calorimetric power measured in a specified bandwidth at the
