Pilot PN Sequence. A pair of modified maximal length PN sequences with period 2
15
used to spread
the Foward CDMA Channel and the Reserve CDMA Channel. Different base station are identified by
different pilot PN sequence offsets.
Pilot PN Sequence Offset Index . The PN offset in units of 64 PN chips of a pilot, relative to the zero
offset pilot PN sequence.
PN Chip. One bit in the PN sequence.
PN Sequence. Pseudonoise sequence. A periodic binary sequence.
Power Control Bit. A bit sent in every 1.25ms interval on the Forward Traffic Channel to signal the
mobile station to increase or decrease its transmit power.
Power Control Group . A 1.25ms interval on the Forward Traffic Channel and the Reverse Traffic
Channel.
See also Power Control Bit.
Power-Down Registration. Au autonomous registration method in which the mobile station registers
on power up.
PPM. Parts per million.
Preamble . See Access Channel Preamble and Traffic Channel Preamble.
Primary CDMA Channel. A CDMA Channel at a pre-assigned frequency assignment used by the
mobile station for initial acquisition. See also Secondary CDMA Channel.
Primary Paging Channel (CDMA). The default code channel (code channel 1) assigned for paging
on a CDMA Channel.
Primary Traffic. The main traffic stream carried between the mobile station and the base station,
supporting the active promaty service option, on the Traffic Channel. See also Secondary Traffic,
Signaling Traffic, and Servic3e Option.
Private Long Code . The long code characterized by the private long code mask. See also Long
Code.
Private Long Code Mask. The long code mask used to form the private long code. See also Public
Long Code Mask and Long Code.
Public Long Code. The long code characterized by the public long code mask.
Public Long Code Mask. The long code mask used to form the private long code. The mask contains
the ESN of the mobile station. See also Private Long Code Mask and Long Code.
Punctured Code. An error-correcting code generated from another error-correcting code by deleting
(i.e., puncturing) code symbols from the code output.
Quick Repeats . Additional transmissions of identical copies of a message within a short interval to
increase the probability that the message is received correctly.
Receive Objective Loudness Rating (ROLR). A perceptually weighted transducer gain of telephone
receivers relating electrical excitation from a reference generator to sound pressure at the earphone.
The receive objective loudness tating is normally specified in dB relative to one Pascal per millivolt.
