Description / Abstract:

Overview

The following are the requirements of the cdma2000 Test Data Service Option Revision A:

• Connects the Service Option at the Multiplex Sublayer.

• Supports both forward and reverse links (asymmetric and symmetric).

• Does bit-wise comparison of the received frame with the locally generated/expected frame to detect the undetected bit errors that are not detected by frame quality bits.

• Maintains separate sets of error statistics for the FCH/DCCH and SCH(s) and responds with this information when queried by the base station.

• Defines a single service option, and sets up different RCs and service configurations on the two links through service negotiation.

• May include simultaneous primary and secondary traffic (for example, can run Markov service [SO 54] on the Fundamental Channel and TDSO on the Supplemental Channel).

• Can be carried by all RC combinations on the reverse/forward links as defined under cdma2000.

• Requires separate channel IDs to differentiate between the Fundamental Channel (FCH), Dedicated Control Channel (DCCH), Supplemental Channel(s) (SCH's).

• Is able to handle multiframe interleaving over 40 ms and 80 ms intervals in the physical layer for SCH.

• Does not preclude a future extension to support flexible/variable rate.

• Allows two types of ON/OFF traffic models to be selectable (Only for FCH, DCCH and SCH):

- Deterministic frame activity given by TX_ON and TX_OFF

- Random frame activity with average frame activity D and average burst length B, in units of Physical Layer frames

• Supports two source types of bits for frame generation (Only for FCH, DCCH and SCH):

- Selectable byte pattern

- Pseudo-random bits

• Supports 5 ms FCH/DCCH frames testing using Layer 3 Signaling mini messages

• Supports testing of all the new physical channels introduced in cdma2000 Revisions C and D
