Problems solved by technology

Although this method can flexibly calculate TBS according to resource allocation, the obtained TBS may be any byte, which obviously does not adapt to the characteristics of NR that only verify and optimize code blocks of a specific length, so that the performance of transmission blocks cannot be guaranteed.

Abstract

The present invention provides a method, an apparatus and a device for determination of the size of a transport block, and relates to the technical field of communication. The method, the apparatus and the device for determination of the size of the transport block are used for ensuring the performances of a transport block in an NR (New Radio) system. The method comprises the steps of: determining the initial size of a transport block; comparing the initial size of the transport block with a threshold value to obtain a comparison result; according to the comparison result, performing quantification of the initial size of the transport block to obtain the initial size of the transport block after quantification; and according to the initial size of the transport block after quantification,determining the final size of the transport block. The method, the apparatus and the device for determination of the size of the transport block are mainly applied in the 5G NR.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and equipment for determining the size of a transport block. Background technique [0002] In LTE (Long Term Evolution, long term evolution), the size of the transport block carried by the data channel can be obtained by looking up a table. LTE data channel resource allocation is based on PRB (Physical Resource Block, physical resource block) pair (pair). When designing the TBS (Transport Block Size, transmission block size) table, it is assumed that each PRB pair can be used for the data channel. The number of REs (Resource Elements, resource units) to be transmitted is fixed. [0003] However, resource allocation of data channels in NR (New Radio, new air interface) is more flexible. For example, one time slot may be allocated for one time slot, one or more symbols, or resources of multiple time slots. Since the resource scheduling in NR is mo...
