Problems solved by technology

[0008] An object of the present invention is to provide a channel establishment method for multi-carrier HSDPA, to solve the technical problem that single-carrier HSDPA only considers the transmission control of a single carrier in the prior art and cannot meet the control requirements of multi-carrier HSDPA
[0009] Another object of the present invention is to provide a multi-carrier downlink packet data transmission method to solve the technical problem in the prior art that it is difficult to increase the peak transmission rate of user packet data

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] see figure 1 , which is a flowchart of a multi-carrier HSDPA channel establishment method provided by the present invention. it includes:

[0031] S110: Determine the number of channel resources used for HSDPA in the cell;

[0032] S120: Find N carriers from the cell according to the number of channel resources required in step S110;

[0033] S130: Allocate the HSDPA channel resources of the cell as HS-DSCH channels and uplink and downlink control channels;

[0034] S140: When the user terminal initiates the HSDPA request and is allowed, the network side allocates the HS-DSCH channel used by the terminal, the HS-SCCH channel and the paired HS-SICH channel that the terminal needs to monitor for the user terminal.

[0035] For downlink packet data transmission of a single carrier, the channel resources of the cell are time slots and code channels. For multi...

Abstract

The invention discloses method for building HSDPA channel of multicarrier, and method for transmitting down going packet data of multicarrier. The method for building the channel includes steps: (1) determining number of resources in use for HSDPA channel in cell; (2) according to number of channel resources required by step (1), finding out N pieces of carrier in cell, the resources of N pieces of carrier constitutes resources of HSDPA channel in this cell; (3) assigning resources of HSDPA channel in this cell into HS-DSCH channel and up / down control channels; (4) when user terminal initiates HSDPA request, and the request is allowed, network side assigns HS-DSCH channel used by this terminal, HS-SCCH channel needed to be monitored by this terminal and paired HS-SICH channel for user's terminal. The method raises peak transmission rate of user packet data, optimizes resources, and further raises resource throughput of system.

Description

technical field [0001] The present invention relates to the field of communications, in particular to HSDPA (High Speed ​​Downlink Packet Access) technology, in particular to a multi-carrier HSDPA channel establishment method and a multi-carrier downlink packet data transmission method. Background technique [0002] The ability to support high-speed mobile packet data services is one of the most important features of the 3G system. The WCDMA R99 version can provide a data rate with a peak rate of 2Mbps, which is basically sufficient for most existing packet services. However, for many data services that require high traffic and delay, such as video, streaming media, and downloading, the system needs to provide higher transmission rates and shorter delays. [0003] For this reason, the HSDPA technology is a technology introduced by the 3GPP organization in the R5 version. HSDPA not only supports high-speed asymmetrical data services, but also minimizes the operator's invest...
