Embodiment Construction

[0069] Referring to the accompanying drawings, preferred embodiments of the present invention will now be described in detail. In these drawings, the same or similar elements are denoted by the same reference numerals even if described in different drawings. In the following description, detailed descriptions of some known functions and configurations incorporated with the present invention are omitted for conciseness.

[0070] First, an exemplary method of applying an uplink power offset value according to an embodiment of the present invention will be described with reference to FIGS. 5A to 6B .

[0071] 5A to 5D show examples of setting the transmission power of the uplink channels of UL_DPCCH and HS-DPCCH in the HSDPA mobile communication system. In particular, FIG. 5A shows an example of setting the transmission power of UL_DPCCH. The transmission power of UL_DPCCH usually has a constant value within one slot, and is basically set to P (unit dB). P is a value determine...

Abstract

A radio network controller (RNC) transmits a power offset for controlling transmission power of an uplink high speed dedicated physical control channel (HS-DPCCH) when a user equipment (UE) enters a handover region, in a mobile communication system including the RNC, a Node B connected to the RNC, and the UE located in one of at least two cell areas occupied by the Node B. The Node B transmits data to the UE over a high speed downlink shared channel (HS-DSCH) and the UE transmits information indicating reception of the data to the Node B over the uplink HS-DPCCH. The RNC informs the UE of a power offset for determining a transmission power increment of the uplink HS-DPCCH, if it is determined that the UE is located in the handover region. The RNC informs the Node B of the power offset so that the Node B can determine a threshold value for determining information indicating reception of the data, depending on the power offset.

Description

[0001] Pursuant to 35 U.S.C. §119, this application claims the title "Apparatus and method for transmitting and receiving uplink power offset information in a mobile communication system supporting HSDPA" filed at the Korean Ministry of Industrial Property on February 17, 2002 ”, and assigned priority to application Serial No. 2002-8873, the contents of which are hereby incorporated by reference. [0002] technical fields [0003] The present invention relates to a power control device and method for a high-speed dedicated physical control channel used in a mobile communication system supporting high-speed downlink packet access (HSDPA), and more particularly to an uplink power offset value for sending and receiving An apparatus and method for transmitting a high-speed dedicated physical control channel. Background technique [0004] HSDPA provides high-speed data transmission to user equipments (UEs) through the high-speed downlink shared channel (HS-DSCH) and its associated...
