Abstract

Disclosed are an interference reporting and resource adjustment method and apparatus, the method comprising: a node reporting, when determining that there is interference, interference indication information to a base station, wherein the interference indication information comprises: an interfered resource, and a signal to interference and noise ratio; after receiving the interference indication information, the base station determining, when it is determined that there is interference according to the signal to interference and noise ratio, the other nodes using the interfered resource; and adjusting a resource used by the other nodes, so as to avoid interference. By means of the present invention, resource collision can be reduced, so that the resource adjustment efficiency of a communication system is improved, and the requirements for applications with characteristics of low time delay and high reliability can be met.

First claim

The invention claimed is:

1. A method for adjusting an available by a base station resource, comprising:
receiving interference indication information reported by a first node, wherein the interference indication information comprises a resource with interference, a Signal to Interference plus Noise Ratio (SINR), and position information of the first node with respect to other nodes;
determining other nodes concurrently accessing the resource with interference upon determining from the SINR that there is interference;
instructing the other nodes to report their position information based on the determination; and
adjusting the available resource accessed by the other nodes according to the position information reported by the other nodes, and the position information of the first node to avoid the interference.

2. The method according to claim 1 , wherein the resource accessed by the other nodes is adjusted by adjusting a resource accessed by a node farther from the first node among the other nodes.

3. The method according to claim 1 , wherein interference indication information further comprises information about a second node capable of correct decoding despite the interference; and
the resource accessed by the other nodes is adjusted by adjusting a resource accessed by a node failing to decode among the other nodes.

4. The method according to claim 1 , wherein the method further comprises:
notifying a node among the other nodes, for which a resource is adjusted, of an adjusted resource.

5. A method for reporting interference, comprising:
determining, by a first node, that there is interference; and
reporting, by the first node, interference indication information to a base station to request the base station to adjust an available resource accessed by other nodes concurrently accessing a resource with interference, wherein the interference indication information comprises the resource with interference, a Signal to Interference plus Noise Ratio (SINR), and position information of the first node with respect to other nodes;
wherein reporting the interference indication information to the base station to request the base station to adjust the available resource accessed by the other nodes concurrently accessing the resource with interference, comprises:
reporting the interference indication information to the base station to request the base station to determine the other nodes concurrently accessing the resource with interference, and to adjust the available resource accessed by the other nodes concurrently accessing the resource with interference according to position information reported by the other nodes and the position information of the first node, upon determining from the SINR that there is interference.

6. The method according to claim 5 , wherein when received signal power is above a received signal threshold, and the SINR is below an SINR threshold, it is determined there is interference.

7. The method according to claim 5 , wherein the interference indication information further comprises information about a second node capable of correct decoding despite interference.

8. A base station for adjusting a resource, comprising at least one processor and a memory; wherein:
the memory is configured to store computer readable program codes; and the at least one processor is configured to execute the computer readable program codes to:
receive interference indication information reported by a first node, wherein the interference indication information comprises a resource with interference, a Signal to Interference plus Noise Ratio (SINR), and position information of the first node with respect to other nodes;
determine other nodes concurrently accessing the resource with interference upon determining from the SINR that there is interference;
instruct the other nodes to report their position information based on the determination; and
adjust the available resource accessed by the other nodes according to the position information reported by the other nodes, and the position information of the first node to avoid the interference.

9. The base station according to claim 8 , wherein the at least one processor is further configured to execute the computer readable program codes to: adjust the resource accessed by the other nodes by adjusting a resource accessed by a node farther from the first node among the other nodes.

10. The base station according to claim 8 , wherein the at least one processor is further configured to execute the computer readable program codes to:
upon determining that the interference indication information further comprises information about a second node capable of correct decoding despite the interference, adjust the resource accessed by the other nodes by adjusting a resource accessed by a node failing to decode among the other nodes.

11. The base station according to claim 8 , wherein the at least one processor is further configured to execute the computer readable program codes to: notify a node among the other nodes, for which a resource is adjusted, of an adjusted resource.

12. The method according to claim 2 , wherein the method further comprises: notifying a node among the other nodes, for which a resource is adjusted, of an adjusted resource.

13. The method according to claim 3 , wherein the method further comprises: notifying a node among the other nodes, for which a resource is adjusted, of an adjusted resource.

14. The base station according to claim 9 , wherein the at least one processor is further configured to execute the computer readable program codes to: notify a node among the other nodes, for which a resource is adjusted, of an adjusted resource.

15. The base station according to claim 10 , wherein the at least one processor is further configured to execute the computer readable program codes to: notify a node among the other nodes, for which a resource is adjusted, of an adjusted resource.
