摘要： This application provides an information transmission method and apparatus. The method includes: receiving first configuration information, where the first configuration information includes a first duration, a second duration, and a first cycle, the first duration is less than the first cycle, and the first duration starts at a start moment of the first cycle; and when a time unit corresponding to an end of the first duration is not later than a time unit corresponding to an end of the second duration, and acknowledgment information is a negative acknowledgment NACK, skipping monitoring, in a next time unit of the time unit corresponding to the end of the second duration, retransmission scheduling control information corresponding to the acknowledgment information. According to technical solutions of this application, power consumption overheads caused by sleep interruption of a receive end due to reception of retransmitted data can be reduced, and reliable data transmission can be ensured.

摘要： This application relates to a communication method and device. A first terminal device sends first SCI in N first time units, where the first SCI indicates first configuration information, the first configuration information includes a resource of a first periodic transmission, the first periodic transmission includes M transmissions, a transmission cycle of the first periodic transmission is a first cycle, the M transmissions include P transmission time units, N is an integer greater than or equal to 1, M is an integer less than or equal to P, and P is an integer greater than N. The first terminal device sends, in N second time units, second SCI associated with the first SCI. The first terminal device does not need to send SCI for all transport blocks of a service of the first periodic transmission. For a second terminal device, a quantity of times of monitoring a control channel and decoding the SCI is reduced, so that power consumption of the second terminal device can be reduced. In addition, because a quantity of pieces of the SCI sent by the first terminal device is reduced, transmission overheads can also be reduced.
