Disclosed are an active antenna device and a test method therefor, for resolving the problem that existing large-scale active antennae cannot be tested by using a traditional test method due to no traditional antenna connectors. The active antenna device comprises: a transceiver array, a radio frequency calibration and test distribution network unit, an antenna passive distribution network unit, an antenna array, and S test connectors, wherein the radio frequency calibration and test distribution network unit is connected to the transceiver array through N data channels and M calibration channels respectively and is connected to the test connectors, and the antenna passive distribution network unit is connected to the radio frequency calibration and test distribution network unit through N data channels and is connected to the antenna array through P data channels, N being a positive integer greater than or equal to 1, M being a positive integer greater than or equal to 1, P being a positive integer greater than or equal to 1, and S being a positive integer greater than or equal to 1.

Active antenna device and test method therefor

A method and device for reporting a capability of UE. A UE receives a capability querying message from a base station, and sends a capability reporting message to the base station. The capability reporting message contains multi-TA capability information of the UE through at least one of an explicit mode and an implicit mode.
