摘要： A device and method for connecting to a WiMAX network can determine an initial signal strength as a function of an uplink propagation path loss between a mobile device and a base station, a noise and interference level value for the base station, a normalized carrier-to-noise value for ranging, and an offset value. If a connection is not established at the initial signal strength, a signal can be retransmitted at a signal strength equal to the initial signal strength plus a step value, where the step value can be determined by designating a fixed number of steps to be used before reaching maximum transmission power.

摘要： In a method of assigning cell reselection parameters to be utilized by user devices served by a first cell associated with a first tracking area, that a first signal frequency is associated with a second tracking area different than the first tracking area is determined. Based on a determination that the first signal frequency is associated with the second tracking area different than the first tracking area, a first set of one or more reselection parameters is assigned to the first signal frequency.

摘要： Systems, methods, and other embodiments associated with scheduling of measurement gaps and on-duration intervals for a wireless station are described. According to one embodiment, a controller for controlling a station that wirelessly communicates with a base station is disclosed. The station is within a wireless range of the base station and one or more neighboring stations. The controller includes a scheduling logic configured to control the station, while the station is in an idle mode, to receive control information from the base station by scheduling a period of time for an on-duration interval. The scheduling logic is configured to control the station to listen to the one or more neighboring stations by scheduling a period of time for a measurement gap. The measurement gap is scheduled to avoid overlapping with the on-duration interval.
