Provided are wireless communication methods and corresponding base stations and user terminals. The wireless communication method performed by the base station includes generating indication information indicating a support capability of the base station for user terminals of different heights and/or types; and transmitting the indication information to user terminals within a cell managed by the base station. The wireless communication method performed by the user terminal includes receiving indication information indicating a support capability of a base station for user terminals of different heights and/or types; and selecting a portion of information that matches its own height and/or type from the indication information.

A synthetic reception strength value in a case of synthesizing indirect waves of radio waves generated due to an obstruction is calculated for each piece of receive antenna coordinate information in consideration of a phase of each indirect wave. Relation information indicating relation between input information and teaching information is generated. The input information is the synthetic reception strength value for each piece of the receive antenna coordinate information corresponding to transmit antenna coordinate information. The teaching information is information indicating a reception state of the radio waves being calculated using a method of actually measuring the radio waves output by the transmit antenna at a position of a receive antenna or a method other than the method of the actual measurement. Strength of the radio waves is estimated by calculating the information indicating the reception state of the radio waves by using the transmit antenna coordinate information for evaluation and the generated relation information.

Methods and apparatus for facilitating the deployment of a wireless extender in combination with a base station at a customer premises are described. Support is provided for data rate testing in combination with configuring one or more aspects of the system such as wireless extender and/or base station transmission power level. By using testing a system can be deployed where one or more devices may use transmission power levels which are less than the maximum permitted transmission power level while still supporting an expected data rate corresponding to a subscriber service level in a reliable manner. In various embodiments DFS channel black and/or white lists are generated for each link taking into consideration the determined transmit power to be used for a given link.

The disclosure provides a method of operating a communication network. The method includes receiving input data related to a state of the communication network and determining an implementation policy for the communication network based on the input data. The implementation policy is a set of features for forming one or more communication links in the communication network over a time interval. The one or more communication links includes at least one communication link between a terrestrial terminal and a high-altitude platform terminal. Determining the implementation policy is based at least in part on utility values of previous policies. The utility values of previous policies are derived using simulation and/or real-world implementation of the previous policies. The communication network is then operated to implement the implementation policy in the time interval.
