A system and method are disclosed for estimating the location of a satellite terminal. The terminal is selected from among a plurality of terminals, and one or more position estimates are generated for a satellite which provides service to the terminal. The position estimated can be generated, for example, by performing a first one or more iterative grid searches over a plurality of potential position estimates for the satellite. A location estimate is subsequently generated for the terminal by performing a second one or more iterative grid searches over a plurality of potential location estimates for the terminal.

Systems and methods are provided for optimizing channel bandwidth while increasing downlink multi-user, multiple-input, multiple-output (DL MU-MIMO) gain. Depending on the access point (AP) platform, for example, APs exhibit certain characteristics regarding DL MU-MIMO gain as a function of the number of DL MU-MIMO clients associated to the AP. Accordingly, APs can be configured to operate in accordance with an algorithm that checks the number of DL MU-MIMO capable clients are associated to an AP, and dynamically switch between single- and dual-radio modes of operation to take advantage of those DL MU-MIMO gains.

A cell reselection control method comprises transmitting from a base station configured to manage a cell belonging to a first frequency, to a radio terminal selecting the cell as a serving cell while being in an idle mode, an intra-frequency redistribution parameter for redistributing the radio terminal to another cell belonging to the first frequency, and an inter-frequency redistribution parameter for redistributing the radio terminal to a second frequency different from the first frequency, receiving, by the radio terminal, the intra-frequency redistribution parameter and the inter-frequency redistribution parameter, and selecting, by the radio terminal, a redistribution target by using at least one of the intra-frequency redistribution parameter and the inter-frequency redistribution parameter, the redistribution target being a frequency or a cell provided with highest priority for cell reselection.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of controlling timer T3440 or T3540 in a User Equipment, UE, the timer being operable to guard a time during which the UE maintains a certain type of connection to a telecommunication network, wherein the timer has a default first time period in the absence of a first condition and a second condition being met, wherein if both the first condition and the second condition are met, then the first default time period is extended to a second time period.

A cell reselection control method according to one embodiment is a method in a mobile communication system. The cell reselection control method a step A of transmitting through a use of broadcast signaling, by a base station, as a redistribution parameter used for a redistribution function, a first redistribution parameter applied to a radio terminal in a first coverage and a second redistribution parameter applied to a radio terminal in a second coverage outside the first coverage, a step B of acquiring, by a radio terminal in an idle mode in the second coverage, the second redistribution parameter transmitted in the step A, and a step C of performing, by the radio terminal, cell reselection using the second redistribution parameter acquired in the step B. The redistribution function is a function of distributing cells and/or frequencies which a plurality of radio terminals in an idle mode reselects by cell reselection. The second coverage is a coverage extended by an enhanced coverage function including repetitive transmissions.

The method includes: A control device that obtains path loss data of a wireless access point AP set, where the AP set includes a plurality of APs, and the path loss data includes a path loss between any two of the plurality of APs. The control device obtains a first calibration group based on the path loss data, and sends first calibration information to a management AP of the first calibration group, where the management AP of the first calibration group is an AP that performs calibration management in the first calibration group. By implementing the foregoing method, the control device may divide a plurality of APs into a plurality of calibration groups based on path loss data between the APs, to decrease a coupling degree between the calibration groups.
