TestMAC

TestMAC is a developer tool for testing the system in a controlled environment. It functions as the L2/L1 interface, which schedules packets according to a predefined launch pattern.

Functional blocks of TestMAC are displayed in the following figure. TestMAC is responsible for scheduling DL packets and validating received UL messages.

TestMAC uses a predefined launch pattern for scheduling. The launch pattern defines the TDD pattern across multiple frames and the test vectors (TVs) used on each slot.

The test vectors contain the L1 configuration for each PHY channel in a given slot. TestMAC obtains the slot timing from L1 via L2 adapter. The timing is indicated by the slot indication message.

TestMAC prepares the FAPI message according to the L1 configuration contained in the TV. If a given slot is an UL, TestMAC parses the corresponding TV and compares the received data with the expected values included in the TV.
