摘要： A system and method for using a NxN multiple input, multiple output (MIMO) data packet signal transceiver for testing multiple data packet signal transceivers. In accordance with one exemplary embodiment, a NxN MIMO access point can be used for simultaneous testing of multiple single input, single output (SISO) data packet signal transceivers. Selective data packet signal corruption (e.g., in the form of data packet signal attenuation), allows for individual testing of the transmit signals from respective ones of the data packet signal transceivers.

摘要： A method for facilitating wireless testing of a radio frequency (RF) signal transceiver device under test (DUT). Using multiple antennas within a shielded enclosure containing the DUT, multiple wireless RF test signals resulting from a RF test signal radiated from the DUT are captured and their respective signal phases are controlled prior to being combined to form a composite RF signal. This process is repeated until power level differences between signal power levels at respective pairs of a selected number of RF signal frequencies have values between predetermined minimum and maximum values, thereby providing compensation for the multipath signal environment within the shielded enclosure, and thereby simulating a wired test signal path during wireless testing of the DUT.

摘要： System and method for facilitating testing of multiple data packet signal transceivers involving data-packet-signal replication and one or more status signals indicating successful and unsuccessful receptions of confirmation signals. Based upon the one or more status signals, one or more control signals cause the replicated data packet signals to be distributed to the devices under test (DUTs) such that, following successful and unsuccessful receptions of confirmation signals, corresponding replicated data packet signals are caused to fail to conform in part or to conform, respectively, with a predetermined data packet signal standard.

摘要： A method for controlling block error rate (BLER) testing of a cellular communication device for a system having a fixed number of BLER data packets. Alternating sequences of downlink (DL) data packets have packet identifiers with a first state, and are separated by additional sequences of DL data packets having packet identifiers with a second state, thereby enabling control of BLER testing of the device to ensure a reliable accumulated count of DL data packets received by the device having packet identifiers only with the second state.

摘要： Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) in which test data packets with varying power levels are transmitted to the DUT for testing the DUT while still ensuring that the DUT remains in receive (RX) mode and is prevented from searching for another data packet signal. Alternatively, in the event that the DUT becomes unresponsive due to searching for another data packet signal, multiple test data packets with sufficient signal power levels to ensure reception by the DUT are transmitted to the DUT to cause the DUT to cease searching for another data packet signal and return to RX mode.

摘要： 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.
摘要翻译：一种使用从接入点到移动终端的下行链路（DL）信号传输以及从所述移动终端到所述接入点的上行链路（UL）信号传输的无线通信测试的方法。无线信号环境中的LTE移动设备的精确块错误率（BLER）测试是通过防止相同的下行链路（DL）数据块的重复传输来实现的，所述相同的下行链路（DL）数据块通常将在接收到负的UL确认（NACK）的上行链路（UL）这是由于先前的DL数据传输解码失败所致，从而产生准确反映数据接收错误的累积NACK计数。
