Example Embodiment

The method for fast processing MAC-hs packet data as shown in Fig. 3 and Fig. 4 is unique in that it includes the following steps: First, in layer one, receive MAC-hs (Media Intervention Layer-High Speed) packet data. Specifically, in order to facilitate the reception and subsequent processing, the MAC-hs packet data can only be received after it passes the CRC, that is, the cyclic redundancy check is correct. Of course, considering the difference of data in actual operation, in order to better carry out the inspection, adaptive modulation and coding (AMC), hybrid automatic repeat request (HARQ) and high-order modulation can be used for verification.

Next, extract the header information (Header) of the MAC-hs packet data. Specifically, the protocol is used to decode the header information of the entity to which the MAC-hs packet data belongs, and obtain the required version flag (VF), queue number (QueueID), transmission sequence number (TSN), size indicator (SID), The number ...

Abstract

The invention relates to a method for quickly processing MAC-hs package data, belonging to the field of telecommunication. The method is characterized by comprising the following steps: receiving the MAC-hs package data in a layer I, solving the head information of the MAC-hs package data to obtain a queue number; then, respectively storing the data in MAC-d format; rearranging the data of the MAC-d format in each queue; and finally, sending the rearranged data in MAC-d format to a layer II. The invention quickly processes the MAC-hs package data in the layer I and reduces high-speed data transmission; in addition, the process totally depends on hardware so as to reduce requirements on a processor and comply with the requirements of high-speed performance and low energy consumption of mobile communication.

Description

A Method of Quickly Processing MAC-hs Packet Data technical field The present invention relates to a method for processing high-speed downlink packet access (HSDPA, HighSpeedDownlinkPacketAccess) in a TD-CDMA mobile station system in a Time Division Duplex Code Division Multiple Access system (TD-SCDMA), in particular to a A method for quickly processing MAC-hs packet data belongs to the field of electrical communication. Background technique In the time division duplex code division multiple access system, in order to meet the user's growing demand for high-speed packet data services, and to better compete with other wireless technologies supporting data services, 3GPP released the fifth version (Rel5) introduced HSDPA technology. Specifically, HSDPA adopts Adaptive Modulation and Coding (AMC) and Hybrid Automatic Repeat Request (HARQ) technologies. At the same time, it introduces high-order modulation (16QAM) and adds a MAC-hs entity for fast data scheduling, which can...
