    摘要: A method for the dynamic configuration of a test chamber for wireless communications is provided. The method includes identifying a current test project to be performed on a test device. The test device is disposed within a test chamber for evaluating one or more interactions of the test device with a wireless communication network. The method also includes determining a test configuration of a wireless connection interface of the test chamber based on the identified current test project and then sending a control signal to the wireless connection interface to set the wireless connection interface to the test configuration. In operation, the test configuration of the wireless connection interface controls which of a plurality of wireless signals of the wireless communication network are emitted within an interior the test chamber.

    摘要: In at least one embodiment, a system for enabling wireless communication for a vehicle is provided. At least one controller to generate first information for the vehicle for transmission to at least one surrounding vehicle or an infrastructure external to the vehicle and to receive second information. The remote active antenna assembly to receive the first information over a cable and wirelessly receive over a wireless communication protocol, a control indicative of the remote active antenna assembly being in one of a transmit mode or a receive mode. The remote active antenna assembly to wirelessly transmit, via a remote active element, the first information in response to the control signal indicating that the remote active assembly is in the transmit mode and to wirelessly receive, via the remote active element, the second information in response to the control signal indicating that the remote active assembly is in the receive mode.

    摘要: There is disclosed a method of operating a radio node arrangement in a radio access network. The method includes receiving signaling from a plurality of antennas, the signaling representing transmissions received by the plurality of antennas; performing a transformation of the signaling into a test beam space representation, the test beam space representation pertaining to a subset of reception beams selected from a set of reception beams; and determining a reception quality representation of the test beam space representation. The method includes, if the reception quality representation fulfils a quality requirement condition set, performing further processing based on the test beam space representation; or otherwise, amending the subset of reception beams and returning to receiving signaling and/or performing a transformation. The disclosure also pertains to related devices and methods.

    摘要: An example method for testing a base station that supports multi-carrier transmission using multiple transceiver units comprises transmitting an interfering test signal in one or more transmit bands for the base station apparatus, using the multiple transceiver units and the antenna array, where the interfering test signal has a total EIRP at least approximately equal to the sum of the respective rated maximum EIRPs for each of the predetermined number of simultaneous carriers. This example method further comprises transmitting a desired test signal to the base station apparatus, in a receive band for the base station apparatus, using a test signal generator and a test antenna separate from the base station apparatus, and evaluating a receiver sensitivity for the base station apparatus, based on the desired test signal, while the interfering test signal is being transmitted.

    摘要: A multi-panel base station test system includes a base station radio unit configured with a plurality of antenna panels positioned at a first end of a test chamber of the multi-panel base station test system. The multi-panel base station test system includes a plurality of test antennas positioned at a second end of the test chamber opposing the first end. The multi-panel base station test system includes a microwave lens positioned between the plurality of antenna panels and the plurality of test antennas in the test chamber. The microwave lens is configured to focus respective beams transmitted from each of the plurality of antenna panels toward respective focal points associated with each of the plurality of test antennas based on steering of the plurality of antenna panels.
