5. An apparatus for transmitting timing information, comprising at least one processor configured to:
carry timing information by using a demodulation reference signal (DMRS); and
transmit the DMRS carrying the timing information to a terminal,
wherein the timing information comprises half frame timing information,
wherein the at least one processor is configured to carry the timing information by using a DMRS sequence of the DMRS,
wherein the at least one processor is configured to carry the timing information by using the DMRS by:
in condition that a number of candidate synchronization signal blocks is 4, defining four different DMRS sequences to be in one-to-one correspondence with four synchronization signal blocks,
wherein the DMRS sequence is mapped to a resource comprising in a part of physical broadcast channel (PBCH) symbols, a part of resource elements (REs) in a frequency band outside a synchronization signal to which the DMRS sequence is mapped; and in remaining PBCH symbols, a part of REs in a PBCH bandwidth to which the DMRS sequence is mapped.
 
7. An apparatus for determining timing information, comprising at least one processor configured to:
receive a demodulation reference signal (DMRS) transmitted by a base station; and
determine timing information carried in the DMRS,
wherein the timing information comprises half frame timing information,
wherein the at least one processor is configured to determine the timing information carried in the DMRS by using a DMRS sequence of the DMRS,
wherein the at least one processor is configured to determine the time information by using the DMRS sequence of the DMRS by:
when a number of candidate synchronization signal blocks is 4, determining the time information by using four different DMRS sequences being in one-to-one correspondence with four synchronization signal blocks,
wherein the DMRS sequence is mapped to a resource comprising in a part of physical broadcast channel (PBCH) symbols, a part of resource elements (REs) in a frequency band outside a synchronization signal to which the DMRS sequence is mapped; and in remaining PBCH symbols, a part of REs in a PBCH bandwidth to which the DMRS sequence is mapped.
