Embodiment Construction

[0282] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0283] The "data" mentioned herein refers to service data such as physical layer transport block, which is different from control signaling and other signaling or information for indication such as downlink control channel or downlink control information on the physical layer. The embodiment of the present invention is aimed at the problem of low ...

Abstract

Provide a data transmission method and device, wherein the method includes: the UE determines the transport block size TBS; the UE determines the time domain resources and frequency resources for transmitting the physical downlink shared channel PDSCH, and the PDSCH is used to transmit the transport block; The UE receives the transport block on the time domain resource and frequency resource. The data transmission method and device provided can reduce the control signaling overhead, thereby improving the transmission efficiency of the system.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data transmission method and device. Background technique [0002] The development of communication technology is going from the communication between people, to the communication between people and things, and then to the communication between things. Along with the diversification of communication forms, the content of communication also presents diversification. From the size of the data packet, the communication of the small data packet is becoming an important part of the communication business. For example, the machine type communication (MTC for short) discussed by the 3rd Generation Partnership Project (3GPP for short) standard organization currently limits the transport block size (TBS for short) of its physical layer. ) does not exceed 1000 bits (bits). The existing system uses a downlink control information format (DCI format for short) when scheduling / controlli...
