Claim
1. A method for determining frame timing, comprising:
receiving, by a terminal device, beam-specific information sent by a network device through a beam, the beam-specific information comprising a sequence number of a time-domain location where a synchronization signal is sent through the beam;
determining, by the terminal device, a time-domain offset between the synchronization signal and the frame timing according to a correspondence of a sequence number of the beam, the sequence number of the time-domain location where the synchronization signal is sent and the time-domain offset; and
determining, by the terminal device, the frame timing according to the time-domain offset.
2. The method of claim 1, wherein the beam-specific information further comprises a system bandwidth indication field, and
the method further comprises:
determining, by the terminal device, according to the system bandwidth indication field, a total bandwidth occupied by a signal received through the beam and a frequency-domain offset between a central frequency point of the total bandwidth and a central frequency point of a cell.
3. The method of claim 1, wherein the beam is a beam of a plurality of beams in a cell where the terminal device is, and synchronization signals sent through different beams have different time-frequency offsets relative to the frame timing.
4. The method of claim 1, wherein the receiving, by the terminal device, the beam-specific information sent by the network device through the beam comprises:
searching, by the terminal device, a search region belonging to the terminal device to acquire the beam specific information.
5. A method for determining frame timing, comprising:
determining, by a network device, a time-domain location where a synchronization signal is sent through a beam of a plurality of beams;
sending, by the network device, the synchronization signal and beam-specific information to a terminal device, wherein the beam-specific information comprises a sequence number of the time-domain location where the synchronization signal is sent through the beam, and the sequence number of the time-domain location is used by the terminal device to determine a time-domain offset between the synchronization signal and the frame timing and determine the frame timing.
6. The method of claim 5, wherein the beam-specific information further comprises a system bandwidth indication field, and the system bandwidth indication field is used to instruct the terminal device to determine, according to the system bandwidth indication field, a total bandwidth occupied by a signal received through the beam and a frequency-domain offset between a central frequency point of the total bandwidth and a central frequency point of a cell.
7. The method of claim 5, wherein synchronization signals sent through different beams have different time-frequency offsets relative to the frame timing.
8. A terminal device, comprising:
a processor; and
a transceiver coupled with the processor,
wherein the processor is configured to receive, through the transceiver, beam-specific information sent by a network device through a beam, the beam-specific information comprising a sequence number of a time-domain location where a synchronization signal is sent through the beam;
determine a time-domain offset between the synchronization signal and frame timing according to a correspondence of a sequence number of the beam, the sequence number of the time-domain location where the synchronization signal is sent and the time-domain offset; and
determine the frame timing according to the time-domain offset.
9. The terminal device of claim 8, wherein the beam-specific information further comprises a system bandwidth indication field, and
the processor is configured to:
determine, according to the system bandwidth indication field, a total bandwidth occupied by a signal received through the beam and a frequency-domain offset between a central frequency point of the total bandwidth and a central frequency point of a cell.
10. The terminal device of claim 8, wherein the beam is a beam of a plurality of beams in a cell where the terminal device is, and synchronization signals sent through different beams have different time-frequency offsets relative to the frame timing.
11. The terminal device of claim 8, wherein the processor is configured to search a search region belonging to the terminal device to acquire, through the transceiver, the beam specific information.
12. A network device, comprising:
a processor;
a transceiver coupled with the processor,
wherein the processor is configured to determine a time-domain location where a synchronization signal is sent through a beam of a plurality of beams; and
send, through the transceiver, the synchronization signal and beam-specific information to a terminal device, wherein the beam-specific information comprises a sequence number of the time-domain location where the synchronization signal is sent through the beam, and the sequence number of the time-domain location is used by the terminal device to determine a time-domain offset between the synchronization signal and frame timing and determine the frame timing.
13. The network device of claim 12, wherein the beam-specific information further comprises a system bandwidth indication field, and the system bandwidth indication field is used to instruct the terminal device to determine, according to the system bandwidth indication field, a total bandwidth occupied by a signal received through the beam and a frequency-domain offset between a central frequency point of the total bandwidth and a central frequency point of a cell.
14. The network device of claim 12, wherein synchronization signals sent through different beams have different time-frequency offsets relative to the frame timing.
