Abstract: A testing apparatus obtains user equipment (UE) parametric measurements with unknown and/or unavailable authentication and security information. The testing apparatus may obtain uplink and downlink parameters of a wireless device after the wireless device initiates registration while an associated timer is activated, enabling the testing apparatus to obtain additional measurement information without security information about the tested wireless device. The apparatus may also measure the UE's transmitted power level prior to the initiation of the authentication procedure. The testing apparatus may determine if a wireless device is to be tested at another frequency pair. If so, the testing apparatus redirects the wireless device to a radio resource at the other frequency pair. The testing apparatus then obtains uplink and downlink parameters for the wireless device by performing pre-registration and intra-registration measurements at the other frequency pair.

Abstract: A method for wireless communications testing using downlink (DL) signal transmissions from an access point to a mobile terminal and uplink (UL) signal transmissions from said mobile terminal to said access point. Accurate block error rate (BLER) testing of LTE mobile devices in a wireless signal environment is enabled by preventing repeated transmissions of the same downlink (DL) data block that would normally follow reception of uplink (UL) transmissions of negative UL acknowledgments (NACKs) caused by failures to decode prior DL data transmissions, thereby producing cumulative NACK counts accurately reflecting data reception errors.

Abstract: Method for testing one or more of a group of radio frequency (RF) data packet signal transceiver devices under test (DUTs) with reduced signal interference from the remaining DUTs. A tester broadcasts a signal containing power control instructions about uplink signal power characteristics for communication with the tester. For example, for the LTE 3GPP standards, such characteristics could include power ramping step size, preamble initial received target power or maximum number of preamble transmissions for uplink signals transmitted from the DUTs. Following initiation of communication between the tester and one or more DUTs, the tester broadcasts a signal containing power control instructions to instruct the remaining DUTs to transmit any future signals with different uplink signal power characteristics.

Abstract: Method for calibrating an over-the air (OTA) test system for testing multiple radio frequency (RF) data packet signal transceiver devices under test (DUTs), as well as using such a calibrated OTA test system for performing such tests. Calibration is achieved by placing a known good device (KGD) in multiple defined locations within the OTA test system, radiating the KGD with RF test signals at each location, and collecting from the KGD at each location channel quality information identifying optimal RF test signal sub-band channels for ensuring reliable communications within the test system. Use of such system includes placing multiple DUTs at the defined locations within the OTA test system and communicating with them wirelessly via the identified optimal RF test signal sub-band channels.

Abstract: A communication controller and a method is provided for synchronizing a wireless communication device and a wireless communication network having two or more transmit antennas, which support transmit diversity. The communication controller and method generally provide for receiving a reference signal from the wireless communication network via each one of at least a pair of the two or more transmit antennas. A preferred phase offset is then determined for the at least pair of transmit antennas, and then transmitted to the wireless communication network.
