Abstract

A method in a user equipment (UE) for determining a transmission data block size is provided. The method includes: obtaining parameters for data transmission, the parameters including at least the number of layers, the number of allocated resource blocks, modulation order and code rate; determining the effective number of resource elements; based on the obtained parameters and the determined An effective number of resource elements is used to determine a transport block size; and one of transmitting and receiving data is performed based on the determined transport block size.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 473,839, entitled "Transmission Data Block Size Determination," filed in the U.S. Patent and Trademark Office on March 20, 2017, the contents of which are incorporated herein by reference. technical field [0003] This specification relates generally to wireless communication systems, and in particular to determining transport block sizes within such systems. Background technique [0004] In 3GPP (3rd Generation Partnership Project), there are studies on new protocols collectively called New Radio (NR) interface for 5G. Various terms are used in the art for this new next generation technology. The terms NR and 5G will be used interchangeably in this disclosure. Also, a base station may be referred to as a gNB instead of an eNB. Alternatively, the term transmit-receive point (TRP) may also be used. [0005] slot structure [0006] NR slots consist of several...
