1. A method for wireless communication by a user equipment (UE), comprising:receiving reference signals from one or more transmission reception points (TRPs) in a wireless communications network;
pre-selecting, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service;
transmitting an uplink (UL) signal to the first TRP;
receiving, from the first TRP, feedback comprising information about the UL signal; and
determining, based at least in part on the feedback, to select the first TRP from which to receive the wireless service,
wherein, at least one of:
the UE performs the method, without a handover command message, to determine a new TRP to camp on in an operating state in which a context of the UE is not stored in the wireless communications network; or
the UE performs the method, without a handover command message, to determine a new TRP to camp on if the context of the UE is stored in the wireless communications network.
