Abstract

Claims (53)

1 . A communication method, performed by a first access point device, comprising:

obtaining first frequency usage record information, wherein the first frequency usage record information is used to indicate frequency occupancy in an available frequency band, and the available frequency band and a terahertz frequency band at least partially overlap; and

determining an operating frequency of the first access point device according to the first frequency usage record information;

wherein obtaining the first frequency usage record information comprises:

receiving the first frequency usage record information on a set broadcast frequency.

2 . The communication method according to claim 1 , wherein the frequency occupancy at least indicates an occupied frequency in the available frequency band, and the operating frequency of the first access point device belongs to a frequency that is not comprised in the first frequency usage record information in the available frequency band.

3 . The communication method according to claim 2 , wherein the frequency occupancy further indicates an unoccupied frequency in the available frequency band.

4 . The communication method according to claim 2 , wherein determining the operating frequency of the first access point device according to the first frequency usage record information comprises:

determining a first frequency according to the first frequency usage record information, wherein the first frequency belongs to a frequency that is not comprised in the first frequency usage record information in the available frequency band;

sending a frequency occupation request, wherein the frequency occupation request comprises indication information of the first frequency;

obtaining second frequency usage record information, wherein the second frequency usage record information is generated according to the frequency occupation request; and

in response to determining that the second frequency usage record information comprises a usage record indicating that the first access point device occupies the first frequency, determining the first frequency as the operating frequency of the first access point device.

5 . The communication method according to claim 4 , wherein the communication method further comprises:

sending the second frequency usage record information, wherein the second frequency usage record information comprises a usage record associated with the operating frequency of the first access point device, and the first frequency usage record information.

6 . The communication method according to claim 5 , wherein the usage record indicating that the first access point device occupies the first frequency comprises an identifier of the first access point device and the indication information of the first frequency.

7 . The communication method according to claim 1 , wherein the communication method further comprises:

sending a first signal on the operating frequency of the first access point device, wherein the first signal is used to establish a communication connection with a terminal.

8 . The communication method according to claim 1 , wherein the communication method further comprises at least one of the following:

receiving a first frequency release notification from an access network device, wherein the first frequency release notification is used to indicate the first access point device to release the operating frequency of the first access point device; or

sending a second frequency release notification, wherein the second frequency release notification is used to notify that the first access point device will release the operating frequency of the first access point device; or

receiving a third frequency release notification, wherein the third frequency release notification is used to notify that an operating frequency of a second access point device will be released.

9 . The communication method according to claim 1 , wherein the first frequency usage record information comprises at least one frequency usage record, and each frequency usage record comprises an identifier of an access point device and indication information of a used frequency.

10 . A communication method, performed by an access network device, comprising:

obtaining first frequency usage record information, wherein the first frequency usage record information is used to indicate frequency occupancy in an available frequency band, and the available frequency band and a terahertz frequency band at least partially overlap; and

sending the first frequency usage record information;

wherein sending the first frequency usage record information comprises:

periodically broadcasting the first frequency usage record information on a set broadcast frequency.

11 . The communication method according to claim 10 , wherein obtaining the first frequency usage record information comprises:

obtaining frequency allocation record information of at least two access network devices, wherein the frequency allocation record information is used to indicate frequencies allocated by the at least two access network devices; and

obtaining the first frequency usage record information according to the frequency allocation record information.

12 . The communication method according to claim 10 , wherein the communication method further comprises:

receiving a frequency occupation request from a first access point device, wherein the frequency occupation request comprises indication information of a first frequency, and the first frequency belongs to a frequency that is not comprised in the first frequency usage record information in the available frequency band;

generating second frequency usage record information based on the frequency occupation request;

sending the second frequency usage record information.

13 . The communication method according to claim 12 , wherein generating the second frequency usage record information based on the frequency occupation request comprises:

in response to determining that the first frequency for the frequency occupation request from the first access point device and a first frequency for a frequency occupation request from another access point device at least partially overlap, adding a usage record associated with a frequency corresponding to an earlier frequency occupation request indicated by a timestamp to the first frequency usage record information, to obtain the second frequency usage record information.

14 . The communication method according to claim 10 , wherein the communication method further comprises at least one of the following:

sending a first frequency release notification to an access point device, wherein the first frequency release notification is used to indicate the access point device to release an operating frequency; or

receiving a second frequency release notification from the access point device, wherein the second frequency release notification is used to notify an access network device that the access point device will release the operating frequency.

15 . The communication method according to claim 10 , wherein the frequency occupancy at least indicates an occupied frequency in the available frequency band.

16 . The communication method according to claim 15 , wherein the first frequency usage record information comprises at least one frequency usage record, and each frequency usage record comprises an identifier of an access point device and indication information of a used frequency.

17 . A communication apparatus, comprising:

one or more processors; and

a memory for storing processor-executable instructions;

wherein the one or more processors are collectively configured to load and execute the processor-executable instructions to implement the communication method according to claim 10 .

18 . A communication apparatus, comprising:

one or more processors; and

a memory for storing processor-executable instructions;

wherein the one or more processors are collectively configured to load and execute the processor-executable instructions to:

obtain first frequency usage record information, wherein the first frequency usage record information is used to indicate frequency occupancy in an available frequency band, and the available frequency band and a terahertz frequency band at least partially overlap; and

determine an operating frequency of a first access point device according to the first frequency usage record information;

wherein the one or more processors are further collectively configured to load and execute the processor-executable instructions to:
