Method and apparatus for storing mobile station physical measurements and MAC performance statistics in a management information base of an access point
View Patent ↗A method and wireless communication system for requesting and obtaining transmit power control (TPC) information. The system includes at least one access point (AP) and at least one wireless transmit/receive unit (WTRU). When the AP decides to adapt the transmit power level of the WTRU, the AP transmits a TPC request frame to the WTRU. In response to receiving the TPC request frame, the WTRU performs one or more physical measurements and sends a TPC report frame back to the AP.
1. A method for use in an access point (AP), the method comprising:
receiving a request from a network management entity (NME) for management information base (MIB) information;
communicating, in response to the request from the NME , a first message from a first management entity to a second management entity, wherein the first and second management entities are in the AP;
communicating, in response to the first message, a measurement request to a wireless transmit/receive unit (WTRU) from the second management entity;
receiving a measurement report from the WTRU at the second management entity; and
storing the measurement report in a MIB of the AP, wherein the stored measurement report is available to the NME.
2. The method of claim 1 , further comprising:
communicating a second message confirming receipt of the first message from the second management entity of the AP to the first management entity of the AP.
3. The method of claim 1 , wherein the measurement report includes an absolute value of a requested measurement.
4. The method of claim 1 , wherein the measurement report includes a statistical average of a requested measurement.
5. The method of claim 1 , wherein the measurement report includes a histogram of values of a parameter over time.
6. The method of claim 1 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a signal-to-noise indicator.
7. The method of claim 1 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a received channel power indicator (RCPI).
8. The method of claim 1 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a link measurement.
9. The method of claim 1 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a clear channel assessment (CCA) busy fraction.
10. The method of claim 1 , wherein the measurement request is a request for a stored measurement of a parameter.
11. The method of claim 1 , wherein the measurement request is a request to perform a new measurement of a parameter.
12. An access point (AP) comprising:
a first management entity configured to:
receive a request from a network management entity (MNE) for management information base (MIB) information; and
communicate a first message in response to the request from the NME;
a second management entity configured to:
receive the communicated first message;
initiate the communication of a measurement request to a wireless transmit/receive unit (WTRU) in response to the first message, and
receive a measurement report from the WTRU,
wherein the first management entity comprises a MIB configured to store the measurement report, and wherein the stored measurement report is available to the NME.
13. The AP of claim 12 wherein the second management entity is further configured to:
communicate a second message confirming receipt of the first message from the second management entity to the first management entity.
14. The AP of claim 12 , wherein the measurement report includes an absolute value of the requested measurement.
15. The AP of claim 12 , wherein the measurement report includes a statistical average of a requested measurement.
16. The AP of claim 12 , wherein the measurement report includes a histogram of values of a parameter over time.
17. The AP of claim 12 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a signal-to-noise indicator.
18. The AP of claim 12 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a received channel power indicator (RCPI).
19. The AP of claim 12 , wherein the measurement request includes a request for a measurement of a parameter, and wherein the parameter includes a link measurement.
20. The AP of claim 12 , wherein the measurement request includes a request for a measurement of a parameter, and
wherein the parameter includes a clear channel assessment (CCA) busy fraction.
21. The AP of claim 12 , wherein the measurement request is a request for a stored measurement of a parameter.
22. The AP of claim 12 , wherein the measurement request is a request to perform a new measurement of a parameter.
23. The method of claim 1 further comprising:
communicating the measurement report to the first management entity.
24. The AP of claim 12 , wherein the second management entity is further configured to communicate the measurement report to the first management entity.
25. The method of claim 1 , wherein the measurement report contains transmit power information or link margin information of the WTRU.
26. The AP of claim 12 , wherein the measurement report contains transmit power information or link margin information of the WTRU.
