Embodiment Construction

[0033] In view of the existing processing flow for receiving service data sent by the base station, the baseband chip in the user equipment needs to cache the entire TB of data, thereby occupying more chip memory. After research, the inventor provides a service data receiving in the communication system The method and the baseband chip realize that when the user equipment receives the service data sent by the base station, the cache of the baseband chip only needs to save part of the CB data, and does not need to reserve the storage space of the entire TB data, thereby saving the memory of the baseband chip .

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 2 What is shown is a schematic flowchart of a specific implementation manner of a method for receiving...

Abstract

The invention discloses a method and a device for receiving service data in a communication system, and a baseband chip. The receiving method comprises the following steps of: receiving the service data, wherein the service data comprises a plurality of data blocks of which each comprises an information code and a check code; performing primary check and secondary check on the service data; and outputting a preset number of information codes which pass the primary check and are subjected to the secondary check. By the technical scheme, a memory of the baseband chip is saved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for receiving business data in a communication system, a receiving device, and a baseband chip. Background technique [0002] Long Term Evolution (LTE, Long Term Evolution) is the evolution of the third generation of mobile communications (3G), which improves and enhances the air access technology of 3G, adopts Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) technology and Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) is the only standard for its wireless network evolution. Under the 20MHz spectrum bandwidth, it can provide a peak rate of 300Mbit / s downlink and 150Mbit / s uplink, while improving the performance of cell edge users, increasing cell capacity and reducing system delay. Compared with 3G, LTE has the advantages of high communication rate, high spectrum utilization, low wireless ...
