Problems solved by technology

[0015] The purpose of the present invention is to provide a method and device for allocating multi-carrier HSDPA control channels for downlink packet data transmission, so as to solve the problem that single-carrier HSDPA only considers the service transmission channel coding process of a single carrier in the prior art and cannot meet the requirements. Technical Problems of Control Requirements of Multi-carrier HSDPA

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] The present invention provides a service transmission channel coding processing method and a corresponding coding device suitable for multi-carrier HSDPA. By adopting the coding scheme of the present invention, HSDPA packet data transmission under multi-carrier can be realized, thereby improving the peak transmission rate and frequency utilization rate of the system. The invention discloses three multi-carrier HSDPA service transmission channel coding processing methods and corresponding coding devices provided by the invention. method one

[0039] see figure 2 , which is a flow chart of the first multi-carrier HSDPA service transmission channel coding processing method provided by the present invention.

Abstract

The invention discloses three schemes for processing channel coding suitable to packet data transmission of multicarrier HSDPA. First scheme: dividing data into N groups, adding CRC to each group of data, sectionalizing code block, encoding channel, treating rate match, carrying out scrambling and interlacing process for N group of matched data, dividing data into N groups again, then rearranged by QAM constellation and mapped to physical channel for transmitting. Second scheme: dividing data needed to send through HS-DSCH channel into groups, carrying out process for encoding each route of data according to single carrier HSDPA, and then through physical channel of a carrier to carry out transmission. Third scheme: N pieces of carrier channel considered as a whole are sent to physical layer, then carrying out process from adding CRC to rearranging QAM constellation, grouping data after rearrangement of QAM constellation, mapping the grouped data to carrier channel for transmission.

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 service transmission channel coding processing method and coding device. 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 investment cost while gr...
