Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate with a first network device in a first communications system (e.g., a non-standalone (NSA) system) prior to initiating a handover to a second communications system (e.g., a standalone (SA) system). In some examples, the UE may receive a first tracking reference signal (TRS) from the first network device using a first transmission configuration indicator (TCI) state. The first network device may include an indication of the first TCI state in a control message. The UE may initiate a handover from the first network device to the second network device. Subsequent to the handover, the UE may receive a second TRS from the second network device. The UE may receive the second TRS using the first TCI state based on determining that one or more antenna port configuration conditions are satisfied.
