Method of facilitating testing of multiple time-division-duplex (TDD) data packet signal transceivers

摘要

Method and system for facilitating testing of multiple time-division-duplex (TDD) data packet signal transceivers. Replicas of a data packet signal are transmitted by a tester to multiple TDD devices under test (DUTs), where the replicated signal is either a null or TDD data packet signal. In one embodiment, replica null data packet signals are transmitted for a predetermined time interval sufficient for the DUTs to synchronize with the tester. In another embodiment, following successful and unsuccessful receptions of responsive signals from respective DUTs indicating successful reception of their respective replica TDD data packet signals and, therefore, synchronization with the tester, corresponding replica TDD data packet signals are provided with data packet signal characteristics causing such replica data packet signals to fail to conform or to conform, respectively, with a predetermined data packet signal standard. Following synchronization, test and responsive data packet signals can be exchanged between the tester and DUTs.

1. A method of facilitating testing of multiple time-division-duplex (TDD) data packet signal transceivers, comprising:
providing a plurality of outgoing data packet signals for a plurality of TDD data packet signal transceivers, wherein each one of said plurality of outgoing data packet signals corresponds to a common data packet signal comprising at least one of
a null data packet signal, anda TDD data packet signal with a data packet signal characteristic;when said common data packet signal comprises a null data packet signal, continuing to provide said plurality of outgoing data packet signals for a predetermined time interval; and when said common data packet signal comprises a TDD data packet signal, responding to successful and unsuccessful receptions of respective ones of a plurality of responsive signals from said plurality of TDD data packet signal transceivers by providing one or more of said plurality of outgoing data packet signals, wherein
each one of said plurality of responsive signals is indicative of a successful reception of a valid data packet by a corresponding one of said plurality of TDD data packet signal transceivers, andfollowing a successful reception of one of said plurality of responsive signals from a corresponding one of said plurality of TDD data packet signal transceivers, a corresponding one of said plurality of outgoing data packet signals is provided with said data packet signal characteristic such that said corresponding one of said plurality of outgoing data packet signals fails to conform with a predetermined data packet signal standard, andfollowing an unsuccessful reception of one of said plurality of responsive signals from a corresponding one of said plurality of TDD data packet signal transceivers, a corresponding one of said plurality of outgoing data packet signals is provided with said data packet signal characteristic such that said corresponding one of said plurality of outgoing data packet signals conforms with said predetermined data packet signal standard.
