セルラ通信システムにおける通信資源の時分割

Title:

セルラ通信システムにおける通信資源の時分割

Document Type and Number:

Japanese Patent JP4388704

Kind Code:

B2

Abstract:

An apparatus and method permit a first, fully loaded base station (13) controlled by a first operator to utilise the unused resources of a second base station (15) controlled by a second operator in a time division duplex cellular communications system. The first base station (13) monitors broadcast channel of the second base station (15) and identifies time slots within the time frame structure and at an assigned carrier frequency which are unused by the second base station (15). It then calculates a new time frame structure and sets up a communications link with a subscriber (17) on the assigned carrier frequency during those time slots which avoid contention with the operations of the second base station (15). The invention, advantageously, does not require synchronisation of the different operator's base stations (13, 15).
