Abstract

The embodiment of the invention provides a hybrid automatic repeat request (HARQ) transmission control method and device. The method comprises the following steps: acquiring an initial transmission parameter of initial data transmission of a terminal, wherein the initial transmission parameter comprises a multiple access sequence identification number and a lead code identification number of the initial data transmission; according to the multiple access sequence identification number and the lead code identification number, determining a time-frequency parameter for HARQ retransmission of theterminal, wherein the time-frequency parameter at least comprises a time domain offset value and a frequency domain offset value; carrying the time-frequency parameter in a retransmission parameter used for indicating the terminal to perform HARQ retransmission, and indicating the retransmission parameter to the terminal. The embodiments of the present invention solve the problem in the prior artthat in a 5G communication system, a terminal uses a grant free mode for transmission, and retransmission easily causes time-frequency resources and MA signal conflicts.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to a hybrid automatic repeat request (HARQ) transmission control method and device. Background technique [0002] With the continuous development of mobile Internet technology and Internet of Things technology, there is a corresponding demand for fifth-generation mobile communication network (5G) technology. In 5G technology, mobile communication scenarios have been divided according to existing requirements, including enhanced mobile broadband (Enhance Mobile Broadband, eMBB), massive Machine Type of Communication (mMTC) and ultra-high reliability and low Delayed communication (Ultra-Reliable LowLatency Communication, URLLC) and other scenarios. [0003] In the 5G communication system, the reliability and delay of wireless communication are required to be higher. In the three scenarios of eMBB, mMTC and URLLC, in order to improve spectrum ut...
