Classification: CPC H | IPC H

Claim 0:
1. A communications apparatus, comprising a processor, wherein the processor is coupled to a memory, and configured to execute instructions stored in the memory, to enable the apparatus to implement the following:
obtaining one or more candidate time domain resources for transmitting a reference signal in one or more time units; and
receiving downlink control information, wherein the downlink control information comprises first indication information and transmission information of a first channel, and the first indication information is used to indicate one or more pieces of the following information:
a time domain resource of a first reference signal, wherein the time domain resource of the first reference signal is one or more time domain resources in the one or more candidate time domain resources;
a time domain resource of a second reference signal, wherein the time domain resource of the second reference signal is one or more symbols in a time domain resource on which the first channel is located; and
a time domain resource on which no reference signal exists in the one or more time units;
wherein the one or more candidate time domain resources comprise a time domain resource determined based on a symbol configuration set in the one or more time units;
wherein the symbol configuration set is a subset or a universal set of a symbol configuration list, wherein each symbol configuration in the symbol configuration list includes index information of a start symbol, information about a quantity of consecutive symbols, and information about a slot offset value corresponding to a time domain resource occupied by an uplink channel or a downlink channel, or each symbol configuration in the symbol configuration list includes information about a slot offset value and a start and length indicator value corresponding to a time domain resource occupied by the uplink channel or the downlink channel, wherein the symbol configuration set is divided into one or more symbol configuration subsets, and the one or more candidate time domain resources are determined based on the one or more symbol configuration subsets; and
wherein the first indication information indicates only a symbol configuration set; and wherein the apparatus is further enabled to implement:
selecting one or more of the candidate time domain resources corresponding to the first and/or the second reference signal and checking whether uplink or downlink configuration of the selected one or more of the candidate time domain resources is consistent with the corresponding reference signal.
