Claim 16:
17. A communications method, comprising:
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; or
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 apparatus is enabled to further implement:
dividing the symbol configuration set into one or more symbol configuration subsets; and
determining the one or more candidate time domain resources based on the one or more symbol configuration subsets;

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.
