Embodiment Construction

[0020] The invention will now be described with reference to the drawings, wherein like reference numerals designate like or corresponding parts throughout the different figures.

[0021] The present invention provides a new approach to the scheduling of uplink channels such as E-DCH. In the example below, the RNC determines the credit value assigned to each UE and then notifies the Node B of the credit value. The Node B can then use these credits to schedule when and at what data rate or transmit power the UE can send data. Alternatively, the RNC informs the UE (via Node B) of the scheduled credit value. The UE can then use the credit as a probability or apply the credit to the scheduling command received from the Node B. The above-mentioned explanation will be further explained with reference to the accompanying drawings.

Abstract

A method of uplink transmission scheduling for a network including at least one radio network controller (RNC), at least one user equipment (UE), and a plurality of Node Bs. The method includes determining a parameter to be applied to an uplink transmission schedule of the at least one UE based on an interference effect caused by the at least one UE to a scheduling Node B or to neighboring Node Bs.

Description

technical field [0001] The present invention relates to wireless communication systems, and more particularly, to a Node B scheduling method applicable to uplink channels, which can reduce the variation of uplink interference in a wireless communication system. Background technique [0002] In radio (wireless) mobile communication systems, the concept of the enhanced uplink dedicated channel (E-DCH) discussed is to address the demand for high-speed uplink. As we all know, a typical wireless communication system network includes multiple mobile stations (MS), multiple base stations (BS), base station controller (BSC), mobile switching center (MSC), packet data serving node (PDSN) or interworking function ( IWF), Public Switched Telephone Network (PSTN), and Internet Protocol (IP) networks. [0003] In Universal Mobile Telecommunications System (UMTS), base stations are called Node Bs, mobile terminals, subscriber units, etc. are called User Equipments (UEs), and base station...
