9. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:
-
send a first configuration parameter value to a first antenna of a wireless network so that a configuration of the first antenna changes based on the first configuration parameter value at a first time; send a second configuration parameter value to the first antenna of the wireless network so that the configuration of the first antenna changes based on the second configuration parameter value at a second time after the first time; if a performance metric value of the wireless network associated with the second configuration parameter value crosses an operational condition and if the first antenna has available resources for achieving a predefined performance improvement for the wireless network, send the first configuration parameter value to the first antenna of the wireless network so that the configuration of the first antenna changes based on the first configuration parameter value at a third time after the second time; if (1) the performance metric value of the wireless network associated with the second configuration parameter value crosses the operational condition, (2) the first antenna does not have adequate available resources for achieving the predefined performance improvement for the wireless network, and (3) a second antenna of the wireless network has available resources for achieving the predefined performance improvement for the wireless network, send a third configuration parameter value to the second antenna so that a configuration of the second antenna changes based on the third configuration parameter value at the third time; and if the performance metric value of the wireless network associated with the second configuration parameter value does not cross the operational condition, send a fourth configuration parameter value to the first antenna of the wireless network so that the configuration of the first antenna changes based on the fourth configuration parameter value at the third time. - View Dependent Claims (10, 11, 12, 13, 14, 15)
