Abstract

A base station, a user equipment (UE), a transmission control method for the base station and a data transmission method for the UE are provided. The base station generates an uplink (UL) resource association message that indicates the association between multiple downlink (DL) transmit (Tx) beams and multiple UL beam recovery resources. The base station transmits the UL resource association message to the UE. Upon detecting that a DL Tx beam failure event occurs on a beam pair link with the base station, the UE performs an UL transmission on a first UL beam recovery resource of the UL beam recovery resources. The base station transmits, in response to the UL transmission of the UE, a beam configuration message to the UE, so as to configure a first DL Tx beam associated with the first UL beam recovery resource into the beam pair links.
