Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] Figure 5 is a schematic diagram of a parallel baseband processing device 500 according to an embodiment of the present invention.

[0043] According to an embodiment of the first aspect of the present invention, a parallel baseband processing device 500 for performing N-bit parallel baseband processing on a transport block in a system using a block coding algorithm for channel coding is provided, where N is greater than 1 .

[0044] In a wireless communication system, the physical layer receives data streams from the MAC sublayer in the form of transport blocks, and these data streams are processed by the baseband at the physical layer to provide transmission services on the wireless link. The baseband processing may be baseband processing for uplink transmissions or baseband processing for downlink transmissions. Block coding algorithms refer to c...

Abstract

The invention provides a method and device for performing N bit parallel baseband processing on a transmission block in a system for coding a channel by using a block coding algorithm. The method comprises the following steps of: performing bit filling operation on the transmission block, then performing error check operation, and finally performing code block partition operation. The bit fillingoperation in the code block partition operation in the prior art is independent and performed before the error check operation, thus N bit parallel baseband processing of a single circuit can be realized before Turbo coding under the condition that extra control signaling and hardware implementation complexity are not increased.

Description

technical field [0001] The present application relates to a method and device for parallel baseband processing, in particular to a method and device for parallel baseband processing in a system using a block coding algorithm for channel coding. Background technique [0002] The goal of the 3GPP Long Term Evolution (3rd Generation Partnership Project, Long Term Evolution) is to provide a higher data transmission rate and a smaller data transmission delay. With the help of technologies such as multiple antenna MIMO (Multiple Input Multiple Output) and 64QAM modulation, LTE R8 (Release 8) can provide a maximum downlink data throughput rate of more than 300 Mbps and a user data transmission delay of less than 5 ms at a bandwidth of 20 MHz. In the LTE Advanced stage, it will support a downlink transmission rate exceeding 1Gbps. These performance indicators undoubtedly put forward high requirements for the development of LTE system equipment, especially in the baseband processing...
