Title:
WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2022021695
Kind Code:
A
Abstract:
To provide a wireless communication system that has an option that achieves frame synchronization control by wire in addition to frame synchronization control in wireless communication, and uses synchronization control by wire in a wireless communication section where there is a lot of interference.SOLUTION: In a wireless communication system, a BS (Base Station) has a synchronization control option by wire in addition to synchronization control by wireless. When the BS adopts the synchronization control option by wire by an instruction or the like from a BSM (BS Master), the BS first performs synchronization control by wire, and then performs the synchronization control by wireless when the synchronization control by wire cannot be performed. A BS (wired slave) 1b resets a self-propelled counter unit 115 by a synchronization code received by wire and transmits a reset counter value to a BS (wired master), and in turn the BS (wired master) detects a delay time.SELECTED DRAWING: Figure 6
