System and method for dynamic feature selection based on latency discovery

Aspects of the subject matter described herein are directed towards indicating to a communications network the bandwidth capability data of a user equipment (mobile) device. This allows distinguishing between legacy user equipment that does not support larger bandwidths from newer user equipment that does. A network can thus limit the bandwidth via one of its supported bandwidth parts to a user equipment's bandwidth capability data, such as the maximum supported static bandwidth part of the legacy user equipment. At the same time, larger bandwidths can be assigned to user equipment devices capable of supporting larger bandwidths. Information elements can be used to communicate the bandwidth data from the user equipment to the network, e.g., during initial communications or as requested by the network. Once obtained, the bandwidth data of a user equipment device can be maintained by the network and forwarded to a target cells as part of cell handovers.

Aspects of the subject disclosure may include, for example, obtaining first positional information comprising a location of a non-stationary entity mobile within an environment, the first positional information obtained from a service provider monitoring a positional status of the non-stationary entity within the environment. A path of the non-stationary entity is predicted according to the first positional information. A delivery device mobile within the environment is directed according to the predicted path to deliver an item to the non-stationary entity. Second positional information is obtained, identifying a location of the delivery device within the environment. A separation distance is calculated between the location of the non-stationary entity and the location of the delivery device within the environment and a delivery opportunity is detected based upon the separation distance not exceeding a threshold distance. Other embodiments are disclosed.

The disclosed technology is directed towards switching the primary cell in a carrier aggregation scenario to improve performance. Measurement data of a mobile device (user equipment) is evaluated with respect to one or more various criteria such as cell carrier bandwidth, cell carrier load, cell-related capability and other carrier data (e.g., dynamic spectrum sharing versus clean, time division duplex or frequency division duplex), and others.
