Abstract

A method for receiving a measurement report includes: transmitting, by an apparatus including a coexistence manager (CM), a measurement request message for acquiring a measurement report from at least one device that uses a channel in a TV band to a coexistence enabler (CE); and receiving, by the apparatus, a measurement response message including the result of the measurement results from the CE. The measurement request message includes a first element indicating which of a primary detection, a detection of a device that uses the TV band, and a channel load measurement is requested. The measurement request message includes at least one of a start frequency, an end frequency, a channel list, and a measurement time related to the measurement, and the measurement report includes at least one selected from among the result of primary detection, the result of the detection of the device that uses the TV band.

Claims

1. A method for obtaining a measurement report, the method comprising:

transmitting, from an apparatus including a coexistence manager (CM) to a coexistence enabler (CE), a measurement request message for obtaining a measurement report from one or more devices using television (TV) bands,

wherein the measurement request message includes a measurement type field indicating what type of measurement is requested among plural types of measurements,

wherein the plural types of measurements include a first type for a detection of a device using TV bands, and a second type for a channel load measurement, and

wherein the measurement request message further includes a start frequency, an end frequency, one or more channel numbers, and a scheduled measurement time;

receiving, by the apparatus from the CE, a first measurement confirmation message to confirm reception of the measurement request;

receiving, by the apparatus from the CE, a measurement response message including the measurement report, after the scheduled measurement time,

wherein the measurement report includes at least one of a result of the detection of the device using TV bands and a result of the channel load measurement;

receiving, by the apparatus from the CE, a resource reconfiguration request message including information regarding a type of the device, registered geographical location, maximum power level, and channel load; and

transmitting, from the apparatus to the CE, a resource reconfiguration response message including information on an allocated resource and maximum power level.

2. The method of claim 1, further comprising:

transmitting, from the apparatus to the CE, a second measurement confirmation message to confirm a reception of the measurement report.

3. The method of claim 1, wherein the measurement report is used to make a decision related to coexistence.

4. The method of claim 1, wherein the CM performs at least one of:

generating a coexistence white space map;

making a decision for coexistence for the one or more devices; and

exchanging information required for the coexistence.

5. The method of claim 1, wherein the one or more devices use different types of network technologies.

6. The method of claim 1, wherein the scheduled measurement time includes at least one of a measurement start time indicating when to start the measurement and a measurement duration.

7. A method for transmitting a measurement report, the method comprising:

receiving, by an apparatus including a coexistence enabler (CE) and from a coexistence manager (CM), a measurement request message for obtaining a measurement report from one or more devices using television (TV) bands,

wherein the measurement request message includes a measurement type field indicating what type of measurement is requested among plural types of measurements,

wherein the plural types of measurements include a first type for a detection of a device using the TV bands, and a second type for a channel load measurement, and

wherein the measurement request message further includes a start frequency, an end frequency, one or more channel numbers, and a scheduled measurement time;

receiving, from the apparatus via the CM, a first measurement confirmation message to confirm reception of the measurement request;

transmitting, from the apparatus to the CM, a measurement response message including the measurement report after the scheduled measurement time,

wherein the measurement report includes at least one of a result of the detection of the device using TV bands and a result of the channel load measurement

transmitting, from the apparatus to the CM, a resource reconfiguration request message including information regarding a type of the device, registered geographical location, maximum power level, and channel load; and

receiving, by the apparatus from the CM, a resource reconfiguration response message including information on an allocated resource and maximum power level.

8. The method of claim 7, further comprising:

receiving, from the CM, a second measurement confirmation message to confirm a reception of the measurement report.

9. The method of claim 7, wherein the measurement report is used to make a decision for coexistence.

10. The method of claim 7, wherein the CM performs at least one of:

generating a coexistence white space map;

making a decision for coexistence for the one or more devices; and

exchanging information required for the coexistence.

11. The method of claim 7, wherein the scheduled measurement time includes at least one of a measurement start time indicating when to start the measurement and a measurement duration.
