General Description

This document specifies procedures for Radio Link Protocol Type 3. Radio Link Protocol Type 3 is used with a cdma2000®¹ Traffic Channel to support CDMA data services. For the remainder of this chapter, Radio Link Protocol Type 3 shall be called RLP.

RLP provides an octet stream transport service over forward and reverse traffic channels. RLP is unaware of higher layer framing; it operates on a featureless octet stream, delivering the octets in the order received.

RLP has procedures to substantially reduce the error rate exhibited by CDMA traffic channels. There is no direct relationship between higher layer packets and the underlying traffic channel frames; a large packet may span multiple traffic channel frames, or a single traffic channel frame may contain all or part of several small higher layer packets.

Section 2 is a general description of RLP that defines its use by any service option for which it is suited. Section 3 defines the RLP procedures for encrypted or non-encrypted applications. Section 4 defines the RLP frame formats.

Some features require capabilities first available in cdma2000 Release A. Systems supporting only cdma2000 Release 0 do not support the following:

• Radio Configurations greater than 5.

• Multiplex options 0x704 and 0xf20.

• Variable Length Frame Mode (VLF).

Some features are included for support of capabilities first available in cdma2000 Release C. Systems supporting cdma2000 Release 0 or cdma2000 Release A or cdma2000 Release B but not cdma2000 Release C do not support the following:

• Multiplex option 0xf00.
