Data transmission method, device and readable storage medium

Abstract

The disclosure discloses a data transmission method, which belongs to the technical field of wireless communication. The method includes: receiving scheduling information sent by a base station in a PDCCH, the scheduling information is used to schedule the transmission of at least two data blocks; acquiring a transmission narrowband set; acquiring a size parameter of an alternate transmission unit; according to the transmission narrowband set and the alternate The size parameter of the transmission unit is to transmit at least two data blocks alternately with the base station by frequency hopping. The disclosure realizes the scheduling of repeated transmission and frequency hopping transmission of multiple data blocks between the terminal and the base station at the same time through the scheduling information in one PDCCH.

Description

technical field

[0001] The present disclosure relates to the technical field of wireless communication, and in particular to a data transmission method, device and readable storage medium. Background technique

[0002] With the continuous development of the Internet of Things, the application of Machine Type Communication (MTC) technology is becoming more and more extensive.

[0003] In related technologies, in order to save scheduling resources and terminal power consumption, the base station in the MTC scenario can schedule the transmission of multiple data blocks in one scheduling; in order to increase the time diversity effect and improve transmission efficiency, in the multi-data block scheduling There is also a requirement to use an alternate transmission mechanism, and at the same time, in order to ensure cross-subframe channel estimation and symbol combination gain, a data block also requires multiple repeated transmissions.

[0004] However, there is no solution fo...
