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. See IEEE Standard 269-1992,
IEEE Standard 661-1979, CCITT Recommendation P.76, and CCITT Recommendation P.79.
Registration. The process by which a mobile station identifies its location and parameters to a base station.
Registration Zone. A collection of one or more base stations treated as a unit when determining whether a
mobile station should perform zone-based registration.
Release. A process that the mobile station and base station use to inform each other of call disconnect.
