Embodiment Construction

[0041] Hereinafter, specific exemplary embodiments of the present invention will be described with reference to the accompanying drawings. As described above, the same components are denoted by the same reference numerals in the drawings. Also, in the following description, detailed descriptions of known functions and configurations incorporated herein are omitted for conciseness.

[0042] Figure 4 shows an E-DCH UE moving in a network including cells that support E-DCH and cells that do not support E-DCH. Reference numerals 401 and 403 indicate cells supporting E-DCH (e.g., cells under the control of a Node B according to the 3GPP Release 6 standard), while reference numeral 402 indicates a cell not supporting E-DCH (e.g., in 3GPP Release 6 standard). Cells under the control of R99 / 4 / 5 Node B). A UE supporting E-DCH (hereinafter referred to as 'E-DCH UE') 411 moves from cell 401 to cell 402 , and an E-DCH UE 412 also moves from cell 402 to cell 403 .

[0043] Therefore, in...

Abstract

A method and an apparatus for uplink data transmission using an enhanced uplink dedicated channel (E-DCH) in a mobile telecommunication system which employs a code division multiple access (CDMA) scheme are provided. User equipment (UE) located in a handover area related to a cell supporting the E-DCH and a cell not supporting the E-DCH configures a radio bearer including the E-DCH and a radio bearer including an uplink dedicated channel (DCH) such that they are mapped to one uplink logical channel, and transmits uplink data through any one radio bearer selected by the UE or a serving radio network controller (SRNC). Thus, a delay time due to radio bearer reconfigurations and signaling overhead for the radio bearer reconfigurations are reduced.

Description

technical field [0001] The present invention relates to Wideband Code Division Multiple Access (hereinafter referred to as 'WCDMA') communication systems. More specifically, the present invention relates to a method for selectively using enhanced uplink when a user equipment (hereafter referred to as 'UE') traverses a network comprising cells that support E-DCH and cells that do not support E-DCH A method and apparatus of a dedicated channel (hereinafter referred to as 'EUDCH' or 'E-DCH') or an uplink dedicated channel (hereinafter referred to as 'DCH') as a transmission path for uplink data transmission. Background technique [0002] Universal Mobile Telecommunications Service (hereinafter referred to as 'UMTS') is a third generation mobile telecommunications system based on the European Mobile Telecommunications System. That is, UMTS is a system based on Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS) employing a WCDMA scheme. UMTS p...
