Embodiment Construction

[0027] In one embodiment of the invention, the network is a UMTS network applying WCDMA technology. In the following, the structure of a UMTS network is briefly discussed with reference to FIG. 1 .

[0028] WCDMA can be structurally divided into a Core Network (CN) 100 , a UMTS Terrestrial Radio Access Network (UTRAN) 120 and User Equipment (UE) 140 . The core network and UTRAN are part of the network infrastructure of the wireless telecommunication system.

[0029] The core network comprises a Serving GPRS Support Node (SGSN) 102 connected to the UTRAN via an lu PS interface. The SGSN represents the central point of the packet switched domain of the core network, and the main task of the SGSN is to send / receive packets to / from user equipments using UTRAN. The SGSN may contain subscriber and location information about user equipment.

[0030] The UTRAN may include at least one Radio Network Subsystem (RNS) 122A, 122B, each RNS including at least one Radio Network Controller...

Abstract

A transmitter is included in a mobile communication network. The transmitter is included configured to transmit to a receiver a data channel and a first control channel controlling data transmissions on the data channel, transmit, on the first control channel, an indicator indicating that there is data transmission to the receiver on the data channel. The transmitter also is configured to omit data transmission on the data channel.

Description

technical field [0001] The invention relates to power control of control channels in mobile communication networks. Background technique [0002] High Speed ​​Downlink Packet Access (HSPDA) is a key feature of Wideband Code Division Multiple Access (WCDMA) that provides high data rate transmission in the CDMA downlink to support multimedia services. Downlink data transmission is provided by a High Speed ​​Physical Shared Control Channel (HS-SCCH) for HS-DSCH and a High Speed ​​Physical Downlink Shared Channel (HS-DSCH) associated with the control channel. The control channel provides the terminal with information that data for that terminal has arrived on the data channel. [0003] The prior art does not introduce a power control mechanism for the control channel prior to data transmission on the data channel. The power of the control channel can be adjusted by applying an open and closed power control mechanism only when data transmission has started. [0004] One of the...
