Problems solved by technology

[0007] It can be seen from the above description that the relevant specifications in 3GPP use 13BIT to define the content of the RI field, and do not consider reducing the load of downlink signaling as much as possible; and the relevant specifications in 3GPP stipulate that each time slot is divided into data based on HSDPA The code channel resources must be the same, which makes resource allocation for HSDPA-based data inflexible

Embodiment Construction

[0012] The core of the present invention is to use the code channel number and the code channel offset to indicate the code channel resources allocated to the data based on HSDPA when performing data transmission based on HSDPA, and the sending end will use the code channel number and the code channel offset based on The HSDPA data are sent to the receiving end respectively; the receiving end receives the corresponding HSDPA-based data according to the received code channel number and code channel offset.

[0013] In the present invention, the code channel offset includes two kinds of start code channel offset and end code channel offset. In this embodiment, the present invention uses the starting code channel offset as an example to describe the technical solution provided by the present invention.

[0014] The present invention uses the number of code channels and the code channel offset to indicate the code channel resources allocated to the data based on HSDPA when transmi...

Abstract

This invention provides a data transmitting method based on high speed down grouped inputting, including the following processes: confirm the emitting end as the code track that needs being sent to the receiving end based on high speed down grouped connected data constant distribution; confirm the number of the code tracks and the side-play amount; the emitting end sends the number of code tracks, the code track's side-play amount and the data based on high speed down grouped connection to the receiving end; the receiving end receives the corresponding data based on high speed down grouped connection according to the relating number of code tracks and side-play amount. This invention reduces the down loading, improves the agility of the data transmission based on high speed down grouped connection.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data transmission method based on high-speed downlink packet access. Background technique [0002] In the communication system, because the HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) technology based on the shared code channel can greatly improve the downlink capability of the communication system, the HSDPA technology has attracted extensive attention. The relevant specifications in 3GPP (Third Generation Partnership Project) have carried out detailed regulations on HSDPA. [0003] The realization of data transmission based on HSDPA requires corresponding signaling support, wherein the correct transmission of TFRI (Transport Format Resource Indicator) in the downlink signaling is necessary for the correct demodulation of HSDPA-based packet data packets during transmission to important. TFRI includes 3 parts: RI (Resource In...
