The wireless device detects a triggering event related to a procedure for a handover from a source network node to a target network node in which the wireless device relies on downlink beam selection. The wireless device determines measurement information to include in a message to send to the target network node. The measurement information is obtained by measuring one or more beams according to at least one of a radio link management configuration, a beam management configuration, and a measurement configuration. In response to detecting the triggering event, the determined measurement information in the message is sent to the target network node. ## Claims ### Claim 1 A method performed by a wireless device in a network, the method comprising: detecting a triggering event related to a procedure for a handover from a source network node to a target network node in which the wireless device relies on downlink beam selection; determining measurement information to include in a message to send to the target network node, the measurement information obtained by measuring one or more beams according to at least one of a radio link management configuration, a beam management configuration, and a measurement configuration; and in response to detecting the triggering event, sending the determined measurement information in the message to the target network node. ### Claim at position 2 -15.
