In some aspects, a transmission configuration is determined based on a set of beams downlinking the base station to the user device and carrying a set of data. The determined transmission configuration is the applied to a transceiver of the user device, which then transmits another set of data carried by another set beams uplinking the user device to the base station. |

System and method for performing measurements of antenna under test offset from center of quiet zone
A system and method are provided to determine equivalent isotropic radiated power (EIRP), effective isotropic sensitivity (EIS) and/or signal quality of a DUT in a test chamber, where the DUT has an AUT that has beam-forming capability and is offset from a center of a quiet zone of the test chamber. The method includes establishing a connection with the DUT using a far-field probe antenna in a far-field of the test chamber relative to the AUT so that the AUT forms a beam in a beam peak direction towards the far-field probe antenna; locking the beam of the AUT in the beam peak direction to prevent subsequent beam forming; and performing a near-field measurement of the EIRP, the EIS and/or the signal quality of the AUT with the beam locked in the beam peak direction using a near-field probe antenna in a near-field of the test chamber. |

Generalized beam management framework
Various aspects of the technology described herein are directed towards a generalized beam management framework in which beam management takes into account interference to steer a beam. Aspects comprise configuring a report request comprising a resource setting with channel state information-reference signal resource data and an associated report setting with parameter data corresponding to the one or more channel state information-reference signal resources. The report request is configured to instruct a user equipment device to include interference information when performing user equipment device beam management and reporting. Upon receiving the report request, the user equipment performs a beam measurement operation that includes interference information when generating the beam management report sent to the network device. |
