Embodiment Construction

[0044] In the following description, the present invention will provide a method for determining the HS-PDSCH power offset for HSDPA services, and a method that enables Node B and UE to share the determined HS-PDSCH power offset through signaling processing Methods.

[0045] 1. The first embodiment

[0046] In the first embodiment of the present invention, the HS-PDSCH power offset is determined by the CRNC, which controls the Node B that transmits the HS-PDSCH. A method will be described below, that is, the CRNC transmits the HS-PDSCH power offset to the Node B through the NBAP message, and transmits the HS-PDSCH power offset to the UE through the RNSAP or RRC message.

[0047] As described in conjunction with prior art ( Figure 1 to Figure 4 ), the CRNC determines the power allocated to the HSDPA service within the total power range available to the Node B. That is to say, CRNC determines the total transmission power that can be used by HS-SCCH and HS-PDSCH, and keeps th...

Abstract

In an asynchronous CDMA mobile communication system supporting HSDPA (High Speed ​​Downlink Packet Access), in order to allocate power to the High Speed ​​Physical Downlink Shared Channel (HS-PDSCH), it is necessary to determine the power offset and provide the determined power offset to the node B and User Equipment (UE). To this end, the HS-PDSCH power offset is determined by the controlling radio network controller (CRNC) and the Node B, and the determined HS-PDSCH power offset is communicated to the UE or the Node B.

Description

[0001] According to the provisions of 35U.S.C§119, this application requires the name "Method for Determining Power Offset of HS-PDSCH in an Asynchronous CDMA Mobile Communication System and its signaling method" and Signaling Method Therefor), filed with the Korean Intellectual Property Office on May 11, 2002, and assigned serial number No. 2002-26055, the contents of which are incorporated herein by reference. . technical field [0002] The present invention generally relates to a downlink packet in a Code Division Multiple Access (Code Division Multiple Access, hereinafter referred to as "CDMA") mobile communication system using High Speed ​​Downlink Packet Access (hereinafter referred to as "HSDPA") The communication method, in particular, relates to a method for allocating power of a High Speed ​​Physical Downlink Shared CHannel (hereinafter referred to as "HS-PDSCH"). Background technique [0003] The mobile communication system has developed from an early circuit-bas...
