Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a flow chart showing a method for transmitting data using a high-speed-downlink shared channel in a cell-forward access channel state according to the present invention. Such as figure 1 Shown, the method in this embodiment comprises the following steps:

[0025] Step S102, the radio network controller sends the configuration information required to transmit data using the high-speed-downlink shared channel in the cell-forward access channel state to the user equipment through a system broadcast message, and the user equipment feeds back measurement information to the base station;

[0026] Step S104, the base station selects the transmission parameters of the high-speed-downlink shared channel according to the measurement information fed back by the user equipment and the measurement results obtained by the base station, and se...

Abstract

The invention provides a method of transmitting data through high speed down sharing channels under the state of district-forward accessed to the channel, comprising: 1. a wireless network controller transmits arrangement information required to transmit the data to a user device through high speed down sharing channels under the state of district-forward accessed to the channel; 2. a base station selects transmission parameter under high speed downstream to share the channel according to the measurement information fed by the user device, and transmits the transmission parameters through the high speed-charging control channel to the user device; 3. the user device detects the high speed-sharing control channel, when the user device detects that, special high speed transmission network tempory identification is present in the high speed sharing control channel, the user device receives the data transmitted on the high speed-down sharing physics channel. According to the invention, data transmission delay is efffectively reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, relates to a method for transmitting data by using a high-speed-downlink shared channel in the state of a cell-forward access channel. Background technique [0002] Currently, in the time division duplex (Time Division Duplex, TDD) standard, the high-speed downlink shared channel (HS-DSCH) is only used in the state of the cell dedicated channel (CELL_DCH), and the network side is establishing the downlink HS-DSCH related information for the UE. When radio bearers are used, a set of high-speed-shared control channel (HS-SCCH), high-speed-shared indication channel (HS-SICH), and high-speed-radio network temporary identifier (H-RNTI) are pre-configured for the UE. This group of HS-SCCH / HS-SICH channels is shared by multiple UEs, and the H-RNTI is dedicated to the UE. The UE judges whether this transmission is directed to itself by identifying the H-RNTI on the HS-...
