Application: Base station, mobile station, communication system, and communication method (Patent ID: US20230397134A1)

The patent filed by Fujitsu Ltd. describes a base station capable of transmitting a synchronization signal at regular intervals in multiple cycles. The base station includes a processor that continuously transmits the synchronization signal in radio signals and controls the radio measurement of a connected mobile station to detect the synchronization signal based on scaled first and second information. The mobile station is then prompted to perform cell selection or re-selection based on reception quality criteria and a measurement cycle determined by multiplying a standard cycle by an integer.

The base station further enables the mobile station to measure a signal from a second cell, different from the first cell, for cell selection or re-selection. Additionally, the base station can generate notification information for the mobile station, including the first information, to facilitate scaling of the second information related to the radio measurement cycle. The synchronization signal and broadcast information can be cyclically transmitted in the first cell using beam sweeping or beam spanning. In a communication system, the base station transmits the synchronization signal, prompts the mobile station to detect it based on second information, and initiates cell selection or re-selection based on reception quality criteria and a scaled measurement cycle.
