CDMA2000 Channel Naming Conventions

CDMA2000 Channel Naming Conventions

Many cdma2000 standards refer to logical channels, physical channels, or both. The following naming conventions apply to all cdma2000 standards.

1 Logical Channel Naming Convention
A logical channel name consists of three lower case letters followed by “ch” (channel). A hyphen is
used after the first letter. Table 1Table 1shows the naming conventions for the logical channels that
are used in this family of standards.

Table 1. Naming Conventions for Logical Channels
First LetterSecond Letter Third letter
f = Forward d = Dedicated t = Traffic
r = Reversec = Commons = Signaling

For example, the logical channel name for the Forward Dedicated Traffic Channel is f-dtch.

2 Physical Channel Naming Convention
Physical channels are represented by upper case abbreviations. As in the case of logical channels,
the first letters in the names of the channels indicate the direction of the channel (i.e., forward or
reverse) and is followed by a hyphen. Table 2Table 2 shows the names and meanings of all the
physical channels designated in cdma2000.

Table 2. Physical Channel Names
Channel Name¹ Physical Channel
F/R-FCH Forward/Reverse Fundamental Channel
F/R-DCCH Forward/Reverse Dedicated Control Channel
F/R-SCCH Forward/Reverse Supplemental Code Channel
F/R-SCH Forward/Reverse Supplemental Channel
F-PCH Paging Channel
F-QPCH Quick Paging Channel
R-ACH Access Channel
F/R-CCCH Forward/Reverse Common Control Channel
F/R-PICH Forward/Reverse Pilot Channel
F-APICH Dedicated Auxiliary Pilot Channel
F-TDPICH Transmit Diversity Pilot Channel
F-ATDPICH Auxiliary Transmit Diversity Pilot Channel
F-SYNCH Sync Channel
F-CPCCH Common Power Control Channel
F-CACH Common Assignment Channel
R-EACH Enhanced Access Channel
F-BCCH Broadcast Control Channel
F-PDCH Forward Packet Date Channel
F-PDCCH Forward Packet Data Control Channel
R-ACKCH Reverse Acknowledgement Channel
R-CQICH Reverse Channel Quality Indicator Channel
F-ACKCH Forward Acknowledgement Channel
F-GCH Forward Grant Channel
F-RCCH Forward Rate Control Channel
R-PDCH Reverse Packet Data Channel
R-PDCCH Reverse Packet Data Control Channel
R-REQCH Reverse Request Channel

1 The notations “F/R” and “Forward/Reverse” represent two different
physical channels (i.e., one forward channel and one reverse
channel)

For example, the physical channel name for the Forward Fundamental Channel is F-FCH.
