Abstract

This application provides a method for configuring a sidelink resource and a communication apparatus. A transmit end user may indicate, by using SCI based on a preempted COT, that last several symbols in a slot are blank symbols, and a receive end may perform LBT in the COT based on a reserved blank, to implement COT sharing. In addition, after the COT is preempted, the transmit end user may flexibly configure periodicity information of a PSFCH resource, and send the periodicity information of the PSFCH resource to a receive end user. With reference to frame structure information, a position of a PSFCH slot in a slot in a corresponding direction can be calculated by users of the transmit end and the receive end by using a modulo operation, to feed back HARQ information in a corresponding slot in which the PSFCH exists.

Claims9

Dependent claims

A method for configuring a sidelink resource, comprising:

receiving first sidelink control information (SCI) in a first slot of a channel occupancy time (COT), wherein the first SCI comprises first indication information, the first indication information indicates whether a blank symbol exists in the same first slot of the COT, wherein the first slot is one of a plurality of slots within the COT, and different slots within the COT have varying blank symbol configurations, and the blank symbol is located in one of N last symbols of the same first slot, wherein N is a natural number;
determining, based on the first indication information, whether the blank symbol exists in the same first slot;
determining a quantity of blank symbols in the same first slot based on the first indication information and a subcarrier spacing of the same first slot in response to the first indication information indicating that the blank symbol exists in the same first slot of the COT;
and
performing listen before talk (LBT) or transmit or receive switching on the blank symbols of the same first slot of the COT.
