Abstract

A method, an apparatus, and a computer program product for wireless communication are provided. In one implementation, an apparatus includes a processing system configured to transmit a scanning schedule to one or more devices, the scanning schedule comprising one or more candidate channels and a scan period corresponding to at least a first device of the one or more devices, and receive a report from the first device in response to the scanning schedule, wherein the report indicates a load on at least one of the one or more candidate channels during the scan period.

First claim

What is claimed is:

1 . An apparatus for wireless communication, comprising:
a processing system configured to:
transmit a scanning schedule to one or more devices, the scanning schedule comprising one or more candidate channels and a scan period corresponding to at least a first device of the one or more devices; and
receive a report from the first device in response to the scanning schedule, wherein the report indicates a load on at least one of the one or more candidate channels during the scan period.

2 . The apparatus of claim 1 , wherein the processing system is further configured to schedule at least a second device of the one or more devices for data transmission service between the second device and the apparatus during the scan period associated with a load scanning operation by the first device.

3 . The apparatus of claim 1 , wherein the scanning schedule further comprises a second scan period corresponding to at least a second device of the one or more devices.

4 . The apparatus of claim 3 , wherein the processing system is further configured to receive a second report from the second device in response to the scanning schedule, wherein the second report indicates a load on at least one of the one or more candidate channels during the second scan period.

5 . The apparatus of claim 3 , wherein the processing system is further configured to schedule the first device for data transmission service between the first device and the apparatus during the second scan period associated with a load scanning operation by the second device.

6 . The apparatus of claim 1 , wherein the first device is an access terminal, and the apparatus is an anchor access point that supports a channel hopping operation of a hopping access point.

7 . The apparatus of claim 1 , wherein the first device is an access terminal, and the apparatus is a hopping access point.

8 . An apparatus for wireless communication, comprising:
a processing system configured to:
receive a scanning schedule from a device, the scanning schedule comprising one or more candidate channels and a scan period corresponding to the apparatus;
measure a load on at least one of the one or more candidate channels during the scan period in response to receipt of the scanning schedule; and
report the measured load on at least one of the one or more candidate channels to the device.

9 . The apparatus of claim 8 , wherein the scanning schedule further comprises a second scan period corresponding to at least a second apparatus.

10 . The apparatus of claim 9 , wherein the apparatus is scheduled for data transmission service between the apparatus and the device during the second scan period associated with a load scanning operation by the second apparatus.

11 . The apparatus of claim 8 , wherein the apparatus is an access terminal, and the device is an anchor access point that supports a channel hopping operation of a hopping access point.

12 . The apparatus of claim 8 , wherein the apparatus is an access terminal, and the device is a hopping access point.

13 . A method of wireless communication at an apparatus, comprising:
transmitting a scanning schedule to one or more devices, the scanning schedule comprising one or more candidate channels and a scan period corresponding to at least a first device of the one or more devices; and receiving a report from the first device in response to the scanning schedule, wherein the report indicates a load on at least one of the one or more candidate channels during the scan period.

14 . The method of claim 13 , further comprising:
scheduling at least a second device of the one or more devices for data transmission service between the second device and the apparatus during the scan period associated with a load scanning operation by the first device.

15 . The method of claim 13 , wherein the scanning schedule further comprises a second scan period corresponding to at least a second device of the one or more devices.

16 . The method of claim 15 , further comprising:
receiving a second report from the second device in response to the scanning schedule, wherein the second report indicates a load on at least one of the one or more candidate channels during the second scan period.

17 . The method of claim 15 , further comprising:
scheduling a first device for data transmission service between the first device and the apparatus during the second scan period associated with a load scanning operation by the second device.

18 . The method of claim 13 , wherein the first device is an access terminal, and the apparatus is an anchor access point that supports a channel hopping operation of a hopping access point.

19 . The method of claim 13 , wherein the first device is an access terminal, and the apparatus is a hopping access point.

20 . A method of wireless communication at an apparatus, comprising:
receiving a scanning schedule from a device, the scanning schedule comprising one or more candidate channels and a scan period corresponding to the apparatus; measuring a load on at least one of the one or more candidate channels during the scan period; and reporting the measured load on at least one of the one or more candidate channels to the device.

21 . The method of claim 20 , wherein the scanning schedule further comprises a second scan period corresponding to at least a second apparatus.

22 . The method of claim 21 , wherein the apparatus is scheduled for data transmission service between the apparatus and the device during the second scan period associated with a load scanning operation by the second apparatus.

23 . The method of claim 20 , wherein the apparatus is an access terminal, and the device is an anchor access point that supports a channel hopping operation of a hopping access point.

24 . The method of claim 20 , wherein the apparatus is an access terminal, and the device is a hopping access point.

25 . An apparatus for wireless communication, comprising:
means for transmitting a scanning schedule to one or more devices, the scanning schedule comprising one or more candidate channels and a scan period corresponding to at least a first device of the one or more devices; and means for receiving a report from the first device in response to the scanning schedule, wherein the report indicates a load on at least one of the one or more candidate channels during the scan period.

26 . An apparatus for wireless communication, comprising:
means for receiving a scanning schedule from a device, the scanning schedule comprising one or more candidate channels and a scan period corresponding to the apparatus; means for measuring a load on at least one of the one or more candidate channels during the scan period in response to receipt of the scanning schedule; and means for reporting the measured load on at least one of the one or more candidate channels to the device.

27 . A computer-readable medium storing computer executable code for wireless communication at an apparatus, comprising code for:
transmitting a scanning schedule to one or more devices, the scanning schedule comprising one or more candidate channels and a scan period corresponding to at least a first device of the one or more devices; and receiving a report from the first device in response to the scanning schedule, wherein the report indicates a load on at least one
