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 ConventionA 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 ChannelsFirst LetterSecond Letter Third letterf = 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 ConventionPhysical 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.

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.
