An electronic device that assesses communication performance is described. During operation, the electronic device receives information specifying a location in an environment. For example, the information may correspond to user-interface activity associated with a user interface. Notably, the user interface may include an augmented reality and the user-interface activity may include defining the location, such as by dropping a pin in the augmented reality. Then, the electronic device provides the information to an access point and/or a controller of the access point, where the location is within communication range of the access point. Next, the electronic device receives, from the access point and/or the controller, measurements of one or more communication performance metrics at or proximate to the location during a time interval. Moreover, the electronic device provides a graphical representation of the communication performance at or proximate to the location based at least in part on the measurements.

The disclosure provides methods and apparatuses for performing beam alignment. In some embodiments, a method of performing beam alignment by a user equipment (UE) of a wireless network, includes determining, by the UE based on a plurality of parameters associated with the UE, a first quality level of a connection of the UE in a first orientation and at a geographical location. The connection uses a first beam from at least one network entity of the wireless network.

The second quality level of the second orientation exceeds the first quality level. The method further includes changing, by the UE, an orientation of the UE from the first orientation to the second orientation.

Channel state determination is performed at a user equipment (UE) of a mobile network. The UE determines one or a plurality of time intervals that may be used for channel measurements, performs a plurality of signal power measurements associated each to one of the time intervals to be used for channel measurement and generates a channel state information as a function of the plurality of the signal power measurements. Information comprising an indication of a plurality of time intervals that may be used for received signal power measurements is generated and sent from an access node (eNB) to the UE. The eNB evaluates a measurement report, received from the UE, that comprises received signal power measurements associated each to one of the time intervals.
