Problems solved by technology

In the connection mode, in the non-cell dedicated channel state, there is no suitable channel for the terminal to report the downlink channel quality indicator to the node B, and only the terminal directly transmits the measurement result to the radio network controller through the signaling of the radio resource control layer , the transmit power situation is known only to the radio network controller, but not to the node B

no. 1 example

[0029] Such as figure 2 Shown is the frame structure of the high-speed forward access channel data frame. The data frame includes a frame header and a payload, wherein the payload includes a plurality of transmission blocks or protocol data units, and transmit power level (Transmit Power Level, TPL) information, and the TPL information unit is existing in the existing protocol , refers to the reference transmit power level of the corresponding high-speed forward access channel during the current transmission time interval, which is -13 (negative) in this example.

no. 2 example

[0031] Such as image 3 Shown is the frame structure of the high-speed forward access channel data frame. The data frame includes a frame header and a payload, wherein the payload includes a plurality of transport blocks or protocol data units, and reference power adjustment value information (reference power adjustment, RPA), and the RPA information unit is existing in the existing protocol refers to the reference power correction value corresponding to the calculation of the transmission power, and the value is 0 in this example.

no. 3 example

[0033] Such as Figure 4 Shown is the frame structure of the high-speed forward access channel data frame. The data frame includes a frame header and a payload, wherein the payload includes multiple transport blocks or protocol data units, the frame header includes a downlink channel quality indicator (Downlink Channel Quality Indicator, CQI, hereinafter referred to as CQI), and the CQI information unit is the present If there is an existing protocol, it is an indication value of the channel quality, which is 15 in this example.

[0034] In the above example, the transmission power information encapsulated in the frame header or payload can be any one of the transmission power level, reference power correction value or downlink channel quality indication, and according to any one of these parameters, the offset value can be determined as After encoding, the offset value is a value without a unit. The mapping relationship between this unitless value (encoded value) and the sp...

Abstract

The present invention provides a transmitting method of emitting power of high speed forward access channel data, including following steps:(1) encapsulating emitting power information in the high speed forward access channel data frame by the wireless net controller; (2) the wireless net control transmitting high speed forward access channel data frame carrying with emitting power information to the node B by IUB interface user surface between the wireless net controller and the node B. The invention makes node B acquire emitting power information.

Description

technical field [0001] The present invention relates to a transmission power transmission method of data in a wireless communication system, and in particular to a high-speed forward access channel data transmission method in a non-community-dedicated channel state in a connection mode using the high-speed downlink packet data access feature Transmission method of transmit power. Background technique [0002] The two basic modes of operation of a terminal are idle mode and connected mode. The connection mode can be further divided into different states: URA_PCH state (Universal mobile telecommunication system Radio access network Register area Paging Channel, universal mobile communication system radio access network registration area paging channel state, hereinafter referred to as URA_PCH), CELL_PCH state (CELLPaging Channel, cell Paging channel state, hereinafter referred to as CELL_PCH), CELL_FACH state (CELL Forward Access Channel, cell forward access channel state, he...
