Abstract: Method, apparatus, and computer program product for a user equipment in a wireless communications system to receive configuration information that has one or more TCI-states. With this configuration information, the user equipment can then determine inactivity on TCI-states. Based on that determination, the user equipment enables either a discontinuous monitoring or a cessation of monitoring on those TCI-states. Each TCI-state corresponds to a radio beam and also corresponds to an antenna panel. By reducing such monitoring, the use equipment can deactivate antenna panels corresponding to the TCI-states. The determination can be done through the use of a timer with various time thresholds based on the TCI-state. The activity being transmitted on those beam can be scheduling received by the user equipment from a network element such as a base station. The TCI-states can also be grouped and the functionality of the invention dealt with on a group basis.

Abstract: Handover failure modes are identified by logging information associated with at least one of a handover failure or a radio link failure. The information identifies whether or not a user equipment was engaged in an exchange of at least one of data traffic or control traffic with a network at the time that the handover failure or radio link failure occurred. The information is stored in a non-transitory computer-readable medium, and the information is reported to the network. The information is reported using a radio link failure or connection failure information signaling message. The severity of the handover failure or radio link failure is evaluated based upon the information.
