US 2007/0167191 A1 · Method and arrangement for minimizing intracell interference in a data transmission system

Abstract

The invention refers to an arrangement and a method for minimizing intracell and/or intercell interference for a data transmission system comprising a scheduler (2). A first base station (BS) receives information from user equipments (UE1-UE4) in a first cell (1), by means of a first antenna system (Rx, Tx). The scheduler (2) identifies the position of each user is and allots a first time slot (TS1) to at least one user equipment (UE1) in a first cell segment (CS1) in the first cell (1). The scheduler (2) also allots the first time slot to at least one user (UE3) equipment in a second cell segment (CS2) in the first cell (1). The antenna system (Rx, Tx) then sends information from the base station (BS) simultaneously to all user equipments (UE1, UE3) allotted to the first time slot.

Method for minimizing intracell and/or intercell interference for a data transmission system comprising a scheduler that manages at least a first cell by communicating with a first base station communicating with a number of user equipments in the first cell via a first antenna system effective in one or more cell segments covering certain directions in the first cell, where the method comprises the steps of;

the first base station receiving information from the user equipments in the first cell, by means of the first antenna system;
the first base station communicating the information to the scheduler;
the scheduler identifying each user equipment in the first cells;
the scheduler identifying in which cell segment each user is positioned;
the scheduler allotting a first time slot to at least one user equipment in a first cell segment in the first cell;
the scheduler allotting the first time slot also to at least one user equipment in a second cell segment in the first cell;
the antenna system sending information from the base station simultaneously to all user equipments allotted to the first time slot.
