Abstract

The embodiment of the present invention discloses a method and device for determining time domain resources, which are used to solve the transmission problem caused by the unclear determination parameter K of the time domain interval in the related art. The method is performed by a terminal device, and includes: determining a second time domain resource occupied by second information corresponding to the first information according to the first time domain resource occupied by the first information and a parameter K; wherein, the K is It is predefined or configured; or the K is indicated by the first information; or the K is obtained according to the processing time of the first information. The embodiment of the present invention solves the transmission problem caused by inconsistent understanding of the parameter K between terminal devices; meanwhile, the terminal device can also transmit the second information through the second time domain resource, thereby improving communication effectiveness.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for determining time domain resources. Background technique [0002] In order to improve the reliability and effectiveness of sidelink (sidelink, or called secondary link / side link / side link / direct communication link / SL) transmission, the NR system introduces sidelink hybrid automatic repeat request ( Hybrid Automatic Repeat reQuest, HARQ). In sidelink transmission, the sending device can send data / control information to the receiving device, and the receiving device judges whether the data / control information is successfully received. If the data / control information is successfully received, the receiving device feeds back ACK to the sending device; otherwise, it feeds back NACK. [0003] Before the receiving device feeds back the ACK / NACK, it usually needs to determine the time domain resource occupied by the Physical Sidelink Feedba...
